Abstract
Description
Technical Field
[0001] This utility model relates to the field of powder dust collector technology, and more specifically, to an explosion-proof powder dust collector. Background Technology
[0002] An explosion-proof powder dust collector is a dust removal device specifically designed to handle flammable and explosive dust. Its core purpose is to prevent explosions caused by excessive dust concentration encountering a source of ignition during industrial production.
[0003] A search revealed that Chinese patent CN212017174U discloses an explosion-proof water-sealed dust collector. This utility model features a purification chamber and an explosion-proof chamber connected by a fan, with a water tank and an explosion relief port installed on both. While performing dust removal, it also addresses explosion-proof hazards. In this utility model, when dust explodes or burns in the outlet pipe connected to the explosion-proof chamber, the shock wave generated by the explosion causes the explosion relief element (explosion relief plate) to rupture, releasing the explosion pressure and preventing the dust explosion or combustion from reaching the outlet pipe. This prevents explosions or fires in other parts of the extraction system and avoids the escalation of the accident.
[0004] When the above-mentioned dust collector is in use, the air inlet bend is connected to the dust collection pipeline through a flange or butterfly valve, and a filter screen is generally installed inside the air inlet bend to filter the dust. Finally, the dust on the filter screen is removed by pulse jet cleaning. However, the range of pulse jet cleaning is limited. When the filter screen is large, it is inconvenient to clean the dust on the filter screen completely, resulting in poor performance. Utility Model Content
[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an explosion-proof powder dust collector, which aims to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an explosion-proof powder dust collector, comprising a dust collection box, an inlet pipe, an outlet pipe, and a collection hopper. The inlet pipe and the outlet pipe are respectively fixedly connected to both sides of the dust collection box, and the collection hopper is fixedly connected to the bottom of the dust collection box. Two partitions are fixedly connected inside the dust collection box. Multiple filter screens are movably arranged on the top of one of the partitions. A cleaning assembly is arranged between the multiple filter screens. The cleaning assembly includes a motor, a rotating shaft, multiple bevel gear sets, multiple lead screws, multiple sliding frames, multiple brush plates, and multiple sliding rods. The motor is fixedly installed on one side of the dust collection box, and the end of the motor's output shaft is fixedly connected to the rotating shaft. Both ends of the rotating shaft are movably connected to the dust collection box through bearings, and the rotating shaft is connected to the multiple lead screws through multiple bevel gear sets. The bottom ends of the multiple lead screws are movably connected to one of the partitions through bearings, and the bottom ends of the multiple sliding rods are fixedly connected to one of the partitions.
[0007] Furthermore, the top ends of the multiple lead screws and multiple slide rods respectively pass through multiple sliding frames, one side of the multiple brush plates respectively contacts multiple filter screen plates, and the other side of the multiple brush plates is fixedly connected to a clamping plate. Bolts are provided on the multiple clamping plates, and the multiple clamping plates are fixed to the multiple sliding frames respectively by multiple bolts.
[0008] As can be seen, in the above technical solution, rotating the bolt and moving it away from the clamping plate releases the fixation between the sliding frame and the brush plate, allowing the brush plate to be cleaned and replaced.
[0009] Furthermore, limiting plates are movably provided on both sides of the multiple filter plates, and the multiple limiting plates are respectively fixedly installed on the top of the inside of the dust collection box and on the top of one of the partitions.
[0010] It can be seen that the above technical solution is designed to facilitate the positioning of the filter plate.
[0011] Furthermore, the front side of the dust collection box is movably connected to a sealed box door via a hinge, and the sealed box door is located on top of one of the partitions.
[0012] As can be seen, the above technical solution facilitates the disassembly and replacement of the filter screen and brush plate.
[0013] Furthermore, a plurality of discharge pipes are fixedly installed on another partition, and the top ends of the plurality of discharge pipes are fixedly connected to guide hoppers, and the top ends of the plurality of guide hoppers are fixedly connected to one of the partitions, and a solenoid valve is fixedly installed on the plurality of discharge pipes.
[0014] Furthermore, a water inlet pipe is fixedly connected to the other side of the dust collector, a threaded piston is threadedly connected to the center of the bottom end of the collecting hopper, and a support frame is fixedly connected to the outer edge of the bottom end of the collecting hopper.
[0015] As can be seen, in the above technical solution, an external water source can enter the hopper through the water inlet pipe to further treat the dust.
[0016] Furthermore, two pressure relief valves are fixedly installed on the top of the dust collector, and a thermometer is fixedly installed on one side of the dust collector.
[0017] The technical effects and advantages of this utility model are as follows:
[0018] 1. This utility model filters dust through multiple filter screens. The filtered air is discharged through the air outlet pipe, forming a complete air duct. The motor drives the rotating shaft to rotate, which in turn drives multiple lead screws to rotate. The lead screws drive multiple sliding frames and multiple brush plates to move downwards. The brushes on the brush plates clean the dust adhering to one side of the filter screen. This cycle is repeated, which facilitates the comprehensive cleaning of dust on multiple filter screens and has a good effect.
[0019] 2. This utility model opens the solenoid valve, allowing dust to fall into the collection hopper through the discharge pipe. The collection hopper contains water, thus treating the dust. Rotating the threaded piston away from the collection hopper discharges the wastewater. Two pressure relief valves release the pressure inside the dust collector, preventing an explosion. A thermometer monitors the temperature changes inside the dust collector in real time; if the temperature exceeds the set safety range, cooling measures are immediately implemented. The structure is simple and has good explosion-proof performance. Attached Figure Description

The bottom ends of the multiple lead screws 804 are movably connected to one of the partitions 12 through bearings. The bottom ends of the multiple sliding rods 807 are fixedly connected to one of the partitions 12.
[0029] Furthermore, the top ends of multiple lead screws 804 and multiple slide rods 807 respectively pass through multiple sliding frames 805, one side of multiple brush plates 806 respectively contacts multiple filter screen plates 16, and the other side of multiple brush plates 806 is fixedly connected to a clamping plate 808.

[0031] Furthermore, multiple discharge pipes 14 are fixedly installed on another partition 12.
