With the adoption of the structure, the faucet is silent when used, and the water curtain is complete during water outlet.

The invention discloses a vibrating type hanging screen for dewatering ore pulp or performing wet screening to ore pulp. A screening machine comprises a rack, a plurality of strands of screening units, a vibration transmission mechanism, an excitation vibration mechanism, a chute in the bottom of the screening machine and an underpinning groove among the strands, wherein each strand of the screening units, hung on the rack, are communicated hollow cavities, vibration screening cavities are segmentally arranged vertically, a screen is arranged on an inclined surface, each vibration screening cavity is of Z-shaped turning, and the excitation vibration mechanism is used for driving vibration transmission frames of all vibration transmission mechanisms to vibrate up and down, and thus, the vibration screening cavities of all screening units on the same vibration transmission frame at the same height vibrate together, and the vibration is transmitted to the screen surface of the vibration screening cavity. Ore pulp is divided into multiple parallel-connection strands to be spread into pulp surfaces respectively due to the spatial structure design, the ore pulp on the screen can be continued and is connected in series to increase the screen penetrating times and the screening penetrating efficiency is improved by high-frequency vibration.

The invention discloses a push-pull hanging and folding screen which is used for dewatering or wet-type screening of ore pulp. The push-pull hanging and folding screen comprises a rack, a plurality of strings of screening units, a push-pull mechanism, a transmission system, a bottom chute and intra-string bottom supporting grooves, the screening units hung on the rack are hollow cavities which are communicated, a movable screening cavity set is arranged vertically in a sectionalized manner, screening nets are arranged on two side faces of screening cavities of the movable screening cavity set, the screening cavities of the movable screening cavity set when being pushed and pulled can be folded in an angle-variable manner, and the transmission system is used to drive each push-pull rod of the push-pull mechanism to be in reciprocating push-pull action to drag the screening cavities positioned at equal-altitude positions of all screening units of a same push-pull rod to be combined together for shaking so as to enable screening faces of the screening cavities to alternate downwards and upwards. Through spatial architecture designing, ore pulp is divided into multiple branches which are parallelly connected to be spread to form ore pulp faces respectively, ore pulp on the screen is continuously connected serially to increase screen permeating times, and an ore pulp layer is turned to improve screen permeating efficiency.

A water-saving self-induction water tap nozzle includes a casing. On inner wall of the casing are opened several small holes led to the front end panel of the casing and on the front end panel of the casing is opened a big hole. A water flow switching body up-down slides in the casing. The hole in the middle of the water flow switching body is in communication with the big hole on the front end panel of the casing and on top of the water flow switching body there is a water-sealing cover for sealing the small holes on the inner wall of the casing. In the hole in the middle of the water flow switching body there is a pressure-bearing moving core, on top of which there is a pressure-bearing board with a throughhole and between the pressure-bearing moving core and the front end panel of the casing is disposed a spring.

The invention relates to a radial flow sedimentation tank into which peripheral water flows and out of which water is drained continuously. The sedimentation tank is characterized in that: the tank body is cylindrical and the lower part is a conical sludge district; by the adoption of the way of water flowing into the tank from periphery, a plurality of water holes for supplying the water to flow into the tank are arranged on a inlet groove; the outlet adopts a cruciform outlet groove for water drainage arranged long the radial direction; outlet weirs are arranged at the two sides of the outlet groove and an adjustable baffle is arranged in the outlet groove; the rate of water flow and the outlet positions of the outlet weirs can be adjusted by regulating the length of the outlet weirs so as to adapt to the change of water flow to keep a best route for the sedimentation of particle substances to enhance the outlet water quality. The adjustable outlet groove which can drain water continuously increases the outlet area to reduce the outlet flow speed, and maintains even distribution of outlet water and the best outlet position; therefore the sedimentation load is increased, the efficiency is enhanced and the investment and floor area are reduced.

The invention relates to the technical field of bathroom accessories, in particular to a shower head with the adjustable water outlet area. The shower head comprises a handle and a water outlet set. The handle comprises a fixed handle and a rotating handle. The water outlet set comprises a fixed water outlet set and more than two movable water outlet sets. A plurality of first water outlet holes are evenly formed in the fixed water outlet set. The first water outlet holes are communicated with a first water inlet channel. A plurality of second water outlet holes are formed in the movable water outlet sets. The second water outlet holes are communicated with a second water inlet channel. The movable water outlet sets can be in stretchy connection to the side edge of the fixed water outlet set. When water flow is connected into the second water inlet channel, the movable water outlet sets stretch in the direction away from the fixed water outlet set. When the water flow is disconnected into the second water inlet channel, the movable water outlet sets retract in the direction towards the fixed water outlet set. Compared with the prior art, the shower head has the advantages that the exquisite structure is utilized for achieving changes of the water outlet area of the shower head, and the requirements of users are effectively met.

The invention provides a tilting plate catalytic reaction tower which comprises a base, wherein a reaction tower main body is arranged on the base; the reaction tower main body consists of a tower bottom, a packing layer and a tower top from bottom to top; a tower bottom seal is arranged at the bottom of the tower bottom; the tower bottom seal is connected with an evacuation or mud discharge valve; an ozone water inlet and a wastewater inlet are formed in a side wall of the tower bottom; catalyst solid packing is filled in the packing layer; a tower top seal head is arranged on the tower top; and a wastewater outlet is formed in a side wall of the tower top. The tilting plate catalytic reaction tower is simple in structure, low in cost and easy to operate and manage and is suitable for sewage treatment, a special structure in the tower and the filled inert noble metal catalyst solid packing are utilized, ozone is subjected to catalytic oxidation to generate hydroxyl radicals to oxidize and degrade readily oxidizable substances in the sewage, and the aim of eliminating organic pollution and odor is achieved. The tilting plate catalytic reaction tower can be combined with an ozone technology and is applied to the field of large-scale sewage treatment.
