[0002] Sulfuric acid slag refers to the residue of the process of making sulfuric acid from pyrite, also known as pyrite baking slag or burning slag. It is a kind of chemical waste slag. Experimental research is being conducted on the recovery and production of reduced iron powder, ferric chloride, iron oxide, etc. from sulphuric acid slag by high-temperature and medium-temperature chlorination methods, as well as the recovery of non-ferrous metals such as copper and cobalt.

[0003] However, in actual applications, when most of the existing sulfuric acid slag is discharged, the slag discharge ends of the slag discharge pipes on different production lines are installed together, and then dust reduction is achieved by using atomization combined with humidification and weight increase, so as to achieve the purpose of centralized discharge and centralized treatment. However, due to different stage-by-stage production needs, some slag discharge pipes are in a shutdown state. At this time, when atomization humidification and dust reduction are carried out, the sprayed mist water will still cover the shutdown slag discharge pipes, which will cause a waste of water resources and is not conducive to promotion and use.

[0004] Therefore, those skilled in the art provide a humidification and dust reduction device for sulfuric acid slag discharge to solve the problems raised in the above background technology. Utility Model Content

[0006] A humidification and dust reduction device for sulfuric acid slag discharge provided in the present application adopts the following technical solution: it includes a spray frame, two supporting columns are fixedly connected to the bottom side of the spray frame, and the two supporting columns are symmetrically distributed. A water injection pipe is fixedly connected to the center of the top side of the spray frame, and a plurality of nozzles are rotatably connected to the bottom side of the spray frame. A sealing plate is slidably connected to the inner wall of the spray frame, and a bidirectional screw is rotatably connected to the left side of the spray frame, and both of the sealing plates are helically sleeved with the bidirectional screw.

[0008] Preferably, a sealing round block is rotatably connected to the inner wall of the water injection pipe.

[0009] Preferably, a hexagonal transmission block is fixedly connected to the left end of the bidirectional lead screw.

[0010] In summary, the present application includes the following beneficial technical effects:

[0011] 1. By providing a sealing plate, an external water pipe is injected into the spray frame through a water injection pipe and sprayed out in the form of atomization from the nozzles. In this way, humidification and dust reduction operations can be achieved. During the humidification and dust reduction operations, according to the actual humidification and dust reduction usage requirements covered by the slag discharge, turn the bidirectional lead screw. When the bidirectional lead screw rotates, it can drive two sealing plates to approach each other simultaneously. The moved sealing plates can adjust the number of nozzles spraying water at the same time, thereby achieving the purpose of saving water resources and being conducive to popularization and use.

[0012] 2. By providing a worm and a worm gear, the output shaft of the motor drives the worm, the worm drives the worm gear to rotate, and the worm gear drives the nozzles to rotate.
