A method and unit for the separation of non-ferrous, ferrous and non-metal portions in bulk material handling, particularly for the recycling of materials for subsequent use, wherein the method comprises: the application of eddy currents for the separation of portions of non-ferrous and conductive materials that jump with respect to portions of the remaining material stream; the detection of metals in portions of materials by means of an analysis of the metals using electromagnetic sensors, and the separation of said metals by mechanical expulsion means, achieving the separation of metallic material portions, such as stainless steel, and others from the portions of non-metals. The unit comprises a first conveyor belt of the portions and eddy current (Foucault) separators, while a second conveyor belt includes electromagnetic metal sensors and selective expulsion means which are controlled by said electromagnetic metal sensors.

The invention discloses a bulk material handling system process and bulk material handling equipment. A bulk material handling system comprises a plurality of multi-span material yards, a track operation type material piling machine, a track operation type material taking machine and a transport truck, wherein the track operation type material piling machine is arranged in the plurality of multi-span material yards and is used for piling materials to a material yard; and the track operation type material taking machine is required to be driven onto the transport truck on the end part of the material yard after material taking operation in the material yard is finished, and is transported to other material yards in the plurality of multi-span material yards through the transport truck for continuous operation. In the invention, the problems of high early-stage investment of the bulk material handling equipment, low utilization rate of the equipment during operation and heavy later-stage maintenance tasks of the equipment at present can be solved; and the system and the equipment are easy and convenient to operate, are easy to link through electric control and are particularly suitable for occasions where the equipment in the bulk material handling system has higher vacancy rate in the plurality of multi-span material yards.

A bulk material handling system and method use a horizontal boom frame supporting a conveyor mechanism for bulk material that is slidable relative to the horizontal boom frame. The conveyor mechanism is positioned such that, with bulk material received at a fixed location, or loading axis, on the horizontal boom frame, a portion of the conveyor mechanism will always be positioned to receive bulk material. The horizontal boom frame can also be made rotatable about the loading axis. By rotating the horizontal boom frame and advancing or withdrawing the conveyor mechanism, the discharge point for bulk materials relative to the loading axis can be altered radially and angularly without interrupting the flow of bulk materials through the system. A supply bridge assembly can be employed to bring the bulk materials to the loading axis of the boom.

A bulk material handling system includes a bulk material handling apparatus to convey bulk material and a bulk material handling accessory to aid the bulk material handling apparatus in conveying the bulk material. The bulk material handling accessory includes a controller having one or more sensors. The controller generates a control signal to adjust operation of the bulk material handling accessory based upon at least one status signal of the one or more sensors. The controller also generates the control signal in accordance with a status signal to control signal response pattern defined by system parameter values. The system parameters include a minimum value to define a minimum level of the control signal associated with fail-safe operation and a maximum value to define a maximum level of the control signal associated with stable operation the bulk material handling accessory.

A system is provided for operating a weighing system and a bulk material handling machinery through a single remote terminal, the terminal being a handheld wireless control unit. The hand held wireless control unit includes a transmitter and receiver which use near field communications to send and receive messages to the weighing system and bulk material handling machinery through a junction box (with its own transmitter and receiver) and control relay (with its own receiver). The junction box can be used to configure the weighing system as well as return data about measured weight recorded by the weighing system. The control relay can pass commands to actuation device that engage mechanisms of the bulk material handling machinery, allowing for remote stopping and starting of the machinery. The system provides improved efficiency by allowing wireless operation of components through a single terminal.

The preset invention provides a bulk material handling accessory (6) such as a conveyor belt cleaner (80) for use in connection with a bulk material handling system. The bulk material handling accessory includes a main frame (92), a scraping member (210) including an arm (252) and a scraper blade (214) pivotally attached to the main frame, and a damper mechanism (302) coupled at one end to the main frame and at another end to the scraping mechanism. A mounting mechanism (232) is attached to the main frame for providing linear and rotational movement of the main frame and the associated scraping member and damper mechanism. The damper mechanism includes a damper (304) having a piston (354) and a housing (338) having a fluid chamber (340). The viscosity of the fluid within the fluid chamber is selectively changeable to change the damping characteristics of the damper mechanism to accommodate changes in operating conditions.

A system including a receptacle having an inlet for receiving a poke material therethrough and a carrier for supporting a flexible bag with a closable discharge spout, containing a bulk material to be deposited in such receptacle, and means operable upon a bag loaded with bulk material being supported thereon such spout being aligned with such receptacle inlet and such spout being opening for jostling such bag to enhance the discharge of material through such spout into such receptacle, wherein such carrier and such receptacle are provided with cooperating configurations facilitating the positioning of such carrier relative to such receptacle with said bag spout aligned with such receptacle inlet.

An intermediate bulk storage container (1) for the storage or transport of particulate catalyst material comprises a vessel (2) having an inner wall defining a containment volume for particulate catalyst material. The vessel (20) comprises a cylindrical wall section (22), a top panel (28) closing the upper end of the cylindrical wall section (22) and a conical base section (24) connected to and tapering inwardly away from the lower end of the cylindrical wall section (22). An opening (30) is provided in the top panel (28) of the container (20) for receiving the catalyst material and a closure member (32) is provided for closing the opening (30). An air tight seal is provided when the opening (30) is closed by the closure member (32). A gas duct (38) is in fluid connection with the vessel (20) for supplying an inert gas to the sealed container (20) or removing gas from the vessel (20) to place the container (20) under a vacuum to mitigate the risk of combustion. The gas duct is closed by a valve (40) for transit or storage.

The invention discloses glassware with a triangular block used in the inner part for stirring materials. The glassware comprises a glassware main body, wherein a rotating shaft support rod is transversely and horizontally arranged in the glassware main body, the two ends of the rotating shaft support rod are separately fixed to the inner side walls at the two sides of the glassware main body, the triangular block is pivoted to the rotating shaft support rod, the triangular block is connected to the rotating shaft support rod in a rotating manner, the inner part of the triangular block is a hollow cavity, a rolling ball body is arranged in the triangular block, the upper end of the glassware main body is provided with a bottle cap, a stirring rod is arranged on the bottom end surface of the bottle cap, the arrangement position of the stirring rod is staggered from that of the triangular block, and an ellipsoidal sieve body is further mounted at the lower end of the stirring rod.
