Embodiment 1

[0016] A kind of salvage equipment for granular materials in liquid, which includes: a liquid pool filled with liquid or an equipment inner cavity, a compressed gas nozzle, a compressed gas source, a discharge port, a fishing pool, a fishing device and a controller, wherein the A fixed liquid level is maintained in the liquid pool or the inner cavity of the equipment, the discharge port is set at the bottom of the liquid pool or the inner cavity of the equipment, and the fishing pool passes through the discharge port and the liquid pool or the inner cavity of the equipment connected, the compressed gas nozzle is installed in the liquid pool or the position where the material is easy to accumulate in the inner cavity of the equipment and the position where the material is easy to accumulate in the fishing pool, and the fishing device is set at the position where the material is easy to accumulate The pool is used to salvage the material in the liquid, and the controller is used ...

Embodiment 2

[0023] Taking the metallurgical slag granulation equipment as an example, the preferred embodiment of the present invention will be further described in detail:

[0024] like figure 1 , 2 As shown, the salvage equipment for granular materials in liquid of the present invention includes: compressed gas nozzle 1, liquid pool 2, discharge port 3, slag removal pool 4, lifting dehydration device 5, liquid medium 6, etc., slag removal pool 4 and The liquid pool 2 is connected through the discharge port 3, the two pools are filled with liquid medium 6, the liquid level is fixed, and the lifting dehydration device 5 is inserted into the slag removal pool 4. After the granular material enters the liquid pool 2, it continues to settle in the liquid medium 6 under the action of gravity, falls to the bottom of the liquid pool 2, and enters the lifting and dehydrating device 5 through the discharge port 3 for lifting and dehydrating operations. When there is too much incoming granular ma...

Abstract

The invention relates to equipment for salvaging granular materials in liquid, comprising a liquid pool or equipment inner cavity containing liquid, compressed gas nozzles, a compressed gas source, adischarge hole, a material salvaging pool, a salvaging device and a controller, wherein a fixed liquid level height is kept in the liquid pool or the equipment inner cavity, the discharge hole is arranged at the bottom of the liquid pool or the equipment inner cavity, the material salvaging pool is connected with the liquid pool or the equipment inner cavity through the discharge hole, the compressed gas nozzles are installed at the position for easy accumulation of materials in the liquid pool or the equipment inner cavity and the position for easy accumulation of the materials in the material salvaging pool, the salvaging device is arranged in the material salvaging pool and used for salvaging the materials in liquid, the controller is used for controlling the compressed gas nozzles to spray compressed gas into the liquid, and the compressed gas is utilized to disturb the liquid to enable the liquid to be in a boiling state, thereby preventing materials from forming shelter materialsand hardening due to the accumulation.

Description

technical field [0001] The invention relates to a device and method for salvaging granular materials in liquids, which uses compressed gas disturbance suspension technology. Background technique [0002] In daily industrial production, during the operation of bucket elevator dehydration equipment, disc elevator, drum filter equipment, etc., it often occurs that the equipment is overloaded and unable to operate due to excessive material accumulation, especially when the above equipment is used in During the production process of metallurgical slag granulation, equipment overload often occurs due to unstable slag incoming material. Metallurgical slag is an inevitable product in the iron and steel smelting production process and one of the main wastes in the metallurgical industry. At present, the utilization rate of slag in our country is low, and most of the slag dumping causes waste of resources, pollutes the environment, destroys the ecological landscape, occupies land, an...
