Technical Field
[0001] This utility model relates to the field of auxiliary components for crushing stone in mines, specifically to a dust removal device for crushing stone in mines. Background Technology
[0002] Existing mining crushers generate a large amount of dust during the crushing process, which escapes from the top of the crusher. This dust not only causes serious pollution when it enters the working environment and the atmosphere, but also poses serious health hazards to construction workers and residents living nearby.
[0003] To remove dust from the air, existing technologies typically involve drawing dust-laden air into a dust collector, where filter elements such as dust filters are used to remove the dust. However, existing dust collectors are designed to handle large amounts of dust generated by crushers, causing the filter elements to experience a significant decrease in dust removal efficiency after a period of use. Since the filter elements are usually fixed inside the dust collector, disassembly and cleaning are inconvenient, making it difficult for the dust collector to operate effectively for extended periods. Utility Model Content
[0004] The purpose of this utility model is to provide a dust removal device for crushed stone in a mine to solve the above-mentioned problems. Several layers of filter dust removal components can be disassembled and assembled on the side of the dust removal box body through a disassembly and assembly assembly. The filtration capacity of the filter elements of the several layers of filter dust removal components increases from top to bottom. In this way, the dust gas is drawn into the dust removal box body through the exhaust pipe. With the help of the several layers of filter elements, the dust gas can be filtered in stages and multiple times, as detailed below.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] The present invention provides a dust removal device for crushed stone in a mine, comprising a dust removal box body, wherein the dust removal box body is a hollow box body, and an exhaust pipe and a draft pipe are respectively fixedly connected to the upper part of one side and the lower part of the other side of the dust removal box body, wherein the draft pipe is a bent pipe with its outer end pointing vertically downward.
[0007] The side of the dust collector body is equipped with several layers of filter dust removal components that can be disassembled and assembled via a disassembly and assembly assembly. These filter dust removal components are used to perform multiple stages of filtration on the passing dust gas.
[0008] Preferably, the outer end of the air intake pipe is fixedly connected to an inverted funnel-shaped wind-gathering hood, and the bottom end of the wind-gathering hood is open.
[0009] Preferably, multiple support legs are vertically fixed around the bottom surface of the dust collection box body.
[0010] Preferably, the filtration and dust removal assembly includes a material passage opening, a storage frame, and a filter element body. The side of the dust collection box body has several material passage openings above the exhaust pipe. The storage frames are all rectangular frames that are open at the top and bottom. The storage frames slide through the corresponding material passage openings and extend into the dust collection box body in a horizontal sliding fit. At the same time, the filter element body is fixedly unfolded and fixed to the inner circumference of the storage frame in a tension fit. A sealing plate is fixedly installed on the outer end face of the storage frame that extends out of the material passage opening. The outer surface of the sealing plate is detachably connected to the dust collection box body through the disassembly and assembly assembly.
[0011] Preferably, the dust collection box body has rectangular frame-shaped limiting flanges placed flat around the perimeter near the material passage opening, and the bottom surface of the material frame and the filter body are supported by the top surface of the corresponding limiting flanges.
[0012] Preferably, the filtration capacity of the filter element body in several layers increases sequentially from top to bottom.
[0013] Preferably, the coverage area of each sealing plate is larger than the corresponding passage opening, a handle is installed in the middle of the outer surface of each sealing plate, and a sealing ring is fixed around the passage opening on the inner surface of each sealing plate, and the sealing ring is attached to and pressed against the side surface of the dust collector body.
[0014] Preferably, each of the disassembly and assembly components includes a fixing block, a mounting plate, and a locking stud. The fixing block is fixedly installed at the front and rear positions of the outer surface of the sealing plate. The top surface of each fixing block has a vertical mating hole, and all mating holes are through holes. The mounting plate is flatly fixed to the outer surface of the dust collector body above the fixing block. The mounting plate has a vertical mounting hole, and the mounting hole and the mating hole are vertically coaxially aligned. Each mounting hole is vertically inserted with a locking stud by means of a threaded engagement, and the lower part of each locking stud coaxially passes through the corresponding mating hole.
[0015] Preferably, all the mating holes are threaded through holes, and all the locking studs pass through the corresponding mating holes in a threaded manner.
[0016] Preferably, the top of each locking stud is coaxially fixed to an end head for easy tightening, and each locking stud is coaxially slidably fitted with a washer on the portion between the bottom surface of the corresponding end head and the top surface of the mounting plate.
[0017] In practical application of the above-mentioned dust removal device for crushed stone in mining, the air-collecting hood is suspended at the location where dusty gas needs to be drawn in for dust removal. Then, the exhaust pipe is connected to an external exhaust system. Several layers of filter dust removal components are detachably assembled on the side of the dust collector body via the disassembly and assembly assembly. The filtration capacity of the filter elements in these layers increases progressively from top to bottom.

The assembly and fixing of the filter dust removal assembly within the dust collection box is simple and easy to implement, facilitating quick assembly of the filter dust removal assembly inside the dust collection box for dust purification. Furthermore, since only tightening the locking stud to disengage it from the mating hole allows the storage frame to slide laterally out of the passage opening, the filter dust removal assembly can be removed from the dust collection box. The disassembly of the filter dust removal assembly within the dust collection box is also simple and easy to implement, facilitating subsequent quick removal of the filter dust removal assembly from the dust collection box for regular and thorough cleaning and maintenance, thus contributing to the long-term effectiveness of the filter dust removal assembly.

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0032] See Figures 1-7 As shown, this utility model provides a dust removal device for crushed stone in a mine, including a dust collection box body 1. The dust collection box body 1 is a hollow box. An exhaust pipe 103 and an exhaust pipe 101 are respectively fixedly connected to the upper part of one side and the lower part of the other side of the dust collection box body 1. The exhaust pipe 103 is a curved pipe with its outer end pointing vertically downward. Several layers of filter dust removal components 2 are detachably assembled on the side of the dust collection box body 1 through a disassembly and assembly assembly 3. These components are used to perform multiple stages of filtration of the passing dust gas. Specifically, each filter dust removal component 2 includes a material passage opening 307, a storage frame 304, and a filter element body 305. Several material passage openings 307 are opened on the side of the dust collection box body 1 above the exhaust pipe 101. All 304 are rectangular frames with open top and bottom, and each of the storage frames 304 slides horizontally through the corresponding passage opening 307 and extends into the dust collector body 1. Simultaneously, the inner circumference of each storage frame 304 is flatly unfolded and fixedly fitted with a filter element body 305 using a tension fit. A sealing plate 302 is fixedly installed on the outer end face of each storage frame 304 extending beyond the passage opening 307, and the outer surface of the sealing plate 302 is detachably connected to the dust collector body 1 via a disassembly and assembly assembly 3. The filtration capacity of the multiple filter elements 305 increases progressively from top to bottom. The advantage of this arrangement is that by drawing dusty gas into the dust collector body 1 through the exhaust pipe 101, the multiple layers of filter elements 305 can perform staged and multiple filtrations of the dusty gas.
[0033] See Figures 1-4As shown, the disassembly and assembly assembly 3 specifically includes a fixing block 205, a mounting plate 201, and a locking stud 206. Fixing blocks 205 are fixedly installed at the front and rear positions of the outer surface of the sealing plate 302. Each fixing block 205 has a vertically opening mating hole 204 on its top surface, and all mating holes 204 are through holes. Mounting plates 201 are horizontally fixedly connected to the outer surface of the dust collector body 1 above the fixing blocks 205. Each mounting plate 201 has a vertically opening mounting hole 207, and the mounting hole 207 and the mating hole 204 are vertically coaxially aligned. A locking stud 206 is vertically inserted into each mounting hole 207 via a threaded connection. Furthermore, the lower part of the locking stud 206 coaxially passes through the corresponding mating hole 204. The purpose of this arrangement is that the filter dust removal assembly 2 can be detachably assembled and placed inside the dust removal box body 1 by means of the lateral sliding engagement between the storage frame 304 of the filter dust removal assembly 2 and the passage opening, and the threaded engagement between the locking stud 206 of the disassembly and assembly assembly 3 and the mating hole 204. At the same time, by simply turning the locking stud 206 to separate it from the mating hole 204, the storage frame 304 can be laterally slid out of the passage opening, thereby allowing the filter dust removal assembly 2 to be removed from the dust removal box body 1. The assembly and disassembly of the filter dust removal assembly 2 inside the dust removal box body 1 is simple and easy to implement.
[0034] See Figures 1-4As shown, the dust collector body 1, the filter dust collection component 2, and the disassembly and assembly component 3 have been optimized as follows: Specifically, the outer end of the air intake pipe 103 is fixedly connected to an inverted funnel-shaped air collecting hood 4, and the bottom end of the air collecting hood 4 is open. Multiple support legs 102 are vertically fixed around the bottom surface of the dust collector body 1. Preferably, the size of the bottom opening of the air collecting hood and the height of the support legs 102 can be freely customized to adapt the dust collector body 1 to use in different processing sites. Optionally, the dust collector body 1 may have rectangular frame-shaped limiting flanges 306 laid flat around its inner circumference near the material passage opening 307. The bottom surfaces of the storage frame 304 and the filter body 305 are supported by the top surfaces of the corresponding limiting flanges 306. Preferably, the bottom surfaces of the storage frame 304 and the filter body 305 are not connected to the top surfaces of the limiting flanges 306. This arrangement facilitates the use of the limiting flanges 306 to provide good and stable support for the storage frame 304 and the filter body 305. Furthermore, the coverage area of the sealing plate 302 is larger than the corresponding passage opening 307. A handle 301 is installed in the middle of the outer surface of the sealing plate 302. A sealing ring 303 is fixed around the passage opening 307 on the inner surface of the sealing plate 302. The sealing ring 303 is attached to and pressed against the side surface of the dust collector body 1. Preferably, when the sealing ring 303 is pressed against the side surface of the dust collector body 1, the inner end face of the storage frame 304 is in contact with the inner surface of the dust collector body 1. This arrangement facilitates the disassembly and assembly of the filter dust collection component 2 by holding the handle 301. At the same time, the sealing ring 303 can seal the area around the passage opening 307 by pressing against the side surface of the dust collector body 1, which helps to reduce gas leakage.
[0035] See Figures 1-7 As shown, specifically in the disassembly and assembly assembly 3, all mating holes 204 are threaded through holes, and all locking studs 206 pass through the corresponding mating holes 204 by thread engagement. This arrangement facilitates the stable assembly of the locking studs 206 and the mating holes 204 by tightening. Furthermore, the top of each locking stud 206 is coaxially fixed to an end head 202 for easy tightening. A washer 203 is coaxially slidably fitted on the portion of the locking stud 206 located between the bottom surface of the corresponding end head 202 and the top surface of the mounting plate 201. This arrangement prevents the locking studs 206 from loosening by tightening the end head 202 and pressing the washer 203 against the surface of the mounting plate 201.
[0036] Using the above structure, in practical use, the dust collection hood 4 is suspended at the position where dusty gas needs to be sucked in for dust removal. Then, the exhaust pipe 101 is connected to the external exhaust equipment. Since several layers of filter dust removal components 2 are detachably assembled on the side of the dust collector body 1 via the disassembly and assembly assembly 3, and the filtration capacity of the filter element bodies 305 of the several layers of filter dust removal components 2 increases progressively from top to bottom, the dusty gas is sucked into the dust collector body 1 through the exhaust pipe 101 via the dust collection hood 4. The multiple layers of filter element bodies 305 can perform multi-stage filtration of the dusty gas, improving the dust removal and purification effect. Furthermore, the horizontal sliding fit between the storage frame 304 of the filter dust removal component 2 and the passage opening, along with the locking screws of the disassembly and assembly assembly 3, further enhances the dust removal and purification effect. The threaded engagement between the column 206 and the mating hole 204 allows the filter dust removal component 2 to be detachably assembled and placed inside the dust collection box body 1. The assembly and fixing method of the filter dust removal component 2 inside the dust collection box body 1 is simple and easy to achieve, facilitating the quick assembly of the filter dust removal component 2 inside the dust collection box body 1 for dust purification. At the same time, since only the locking column 206 needs to be turned to disengage from the mating hole 204, the storage frame 304 can slide laterally out of the passage opening, thereby allowing the filter dust removal component 2 to be removed from the dust collection box body 1. The disassembly method of the filter dust removal component 2 inside the dust collection box body 1 is simple and easy to achieve, facilitating the quick removal of the filter dust removal component 2 from the dust collection box body 1 for regular and thorough cleaning and maintenance, which is conducive to maintaining the long-term use of the filter dust removal component 2.
[0037] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
