Description

TECHNICAL FIELD

[0001] The utility model relates to the field of lead-zinc ore dressing, in particular to a lead-zinc ore preselection dust removal equipment. BACKGROUND

[0002] In the process of lead-zinc ore dressing, mineral substances (ore, etc.) are conveyed to the ground in the mine by a conveyor, and then subjected to crushing, primary selection, flotation and other processes until the requirements are met. In this process, the ore is conveyed by a conveyor.

[0003] In order to improve the raw ore grade of the selected ore and reduce the discharge amount of tailings sand into the tailings pond, a waste throwing device is added so that the thrown waste rock can be sold as building stone, thereby increasing the economic benefits of the concentrator, reducing the discharge amount of tailings sand, and increasing the service life of the tailings pond.

[0004] During the waste throwing process, a large amount of dust is generated, so a corresponding bag dust collector is installed on each waste throwing process to absorb the dust.

[0005] However, after a long period of work, it was found that when cleaning the discharge port at the bottom of the bag dust collector, the dust accumulated inside was so much that the operator would still be covered in dust during cleaning, and the surrounding environment would be polluted.

[0006] Therefore, a discharge structure that is easy to operate and avoids secondary pollution is needed. UTILITY MODEL CONTENT

[0007] The utility model aims to provide a lead-zinc ore preselection dust removal equipment.

[0008] The utility model is implemented by the following technical solutions:

[0009] A lead-zinc ore preselection dust removal equipment includes a bag dust collector and a discharge hopper. The discharge hopper is fixedly installed at the bottom of the bag dust collector. A rotating ring is embedded on the outside of the discharge hopper. A movable rod is inserted into the rotating ring in a sliding connection. A blocking block is embedded at the bottom end of the discharge hopper. An L-shaped connecting rod is fixedly connected to the center of the bottom end of the blocking block. A dovetail groove is arranged at the top end of the L-shaped connecting rod. A dovetail block is slidingly connected in the dovetail groove. The top end of the dovetail block is fixedly connected to the bottom end of the movable rod. Locking bolts are screwed onto the rotating ring.

[0010] Preferably, a fixed ring is fixedly sleeved on the outer wall of the rotating ring. A plurality of clamping blocks are arranged in the fixed ring. An adjusting screw is rotatably connected to the side wall of each clamping block. One end of each adjusting screw passes through the corresponding fixed ring and is threadedly connected thereto.

[0011] Preferably, the top end of the blocking block is conical, and the top end of the blocking block is fixedly connected with two anti-blocking rods, the anti-blocking rods are in the shape of H as a whole, and one of the vertical rods of the anti-blocking rods is arranged in an inclined manner and is arranged in close contact with the inner wall of the discharge hopper.

[0012] The utility model discloses the advantages of: through being provided with the moving rod, utilize the moving rod to drive L type connecting rod to descend, thereby drive the blocking block to descend, thereby realize the discharge work, be provided with the fixed ring, utilize locking screw and clamping block to make the collection bag not need handheld and can fix, like this realize simple sealing, thereby avoid appearing secondary pollution, and be provided with two anti-blocking rods, after rotating, make the anti-blocking rod also follow rotation, thereby avoid appearing the condition of blocking, can also make the cleaning can be more clean.
