Description

Technical Field

[0001] This utility model relates to a bag filter dust collector that is easy to disassemble and clean, and belongs to the technical field of bag filter dust collectors. Background Technology

[0002] Industrial production generates a large amount of waste gas containing solid suspended particulate matter. If this waste gas is directly discharged into the atmosphere, it will cause environmental pollution and disrupt the ecological balance. Therefore, this waste gas needs to be treated by dust removal and filtration before being discharged. There are many existing dust removal devices, and bag filters are widely used by large, medium and small enterprises due to their simple structure and ease of use.

[0003] Chinese Patent Publication No. (CN 213253481 U) discloses a bag filter dust collector that is easy to disassemble, belonging to the technical field of bag filter dust collectors. It includes a housing, a dust hopper, and a dust collection box. A sealed door is provided on the side wall of the housing. An exhaust fan is fixedly connected to the top of the housing. An installation frame is provided inside the housing, and an installation plate is fixedly connected to the installation frame. The installation plate has a through hole, and a limiting groove is formed in the wall of the through hole. Two insertion holes are provided on the upper surface of the installation plate, symmetrical about the through hole, and communicate with the limiting groove. A ring is fixedly connected to the top of the filter bag, and two limiting blocks are fixedly connected to the outer wall of the ring, symmetrical about the center of the ring, and the limiting blocks can pass through the insertion holes. This application has the effect of convenient and quick disassembly of the filter bag.

[0004] The bag filter dust collector in the above-mentioned device has a relatively complex installation structure. It cannot fix multiple filter bags at the same time, nor can it release multiple filter bags at the same time. Therefore, when it is necessary to disassemble and install the filter bags in a unified manner, it often takes a lot of time. The process is cumbersome, resulting in high labor costs for disassembly and making it inconvenient for operators to use.

[0005] Therefore, a bag filter dust collector that is easy to disassemble and clean is proposed. Utility Model Content

[0006] In view of this, the present invention provides a bag filter dust collector that is easy to disassemble and clean, so as to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial option.

[0007] The technical solution of this utility model is implemented as follows: A bag filter dust collector that is easy to disassemble and clean includes a filter box.

[0008] More preferably, the output end of the motor is fixedly connected to a connecting rod, and each of the surfaces of the connecting rod is fixedly mounted with a driving bevel gear, and the surfaces of the five driving bevel gears mesh with the surfaces of the five driven bevel gears.

[0009] More preferably, slots are provided on both the front and rear sides of the air guide tube, and the five filter bags are inserted into the inner surface of the bottom of the air guide tube. The five filter bags are interconnected with the air guide tube. Insertion holes are provided on both the front and rear sides of the filter bags, and the insertion rods pass through the inner cavity of the slots and are inserted into the inner cavity of the insertion holes.

[0010] More preferably, the inner cavities of the slot and the socket are both in the same horizontal direction, and the inner cavities of the slot and the socket are interconnected.

Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0028] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0029] Example 1

[0030] like Figure 1-6As shown, this utility model embodiment provides a bag filter dust collector that is easy to disassemble and clean, including a filter box 1. An air inlet 3 is fixedly installed on the left side of the filter box 1, and an exhaust port 4 is fixedly installed on the bottom of the filter box 1. An air guide pipe 7 is connected to the right side of the air inlet 3. Filter bags 8 are provided at the bottom of the air guide pipe 7. A door 5 is movably connected to the front side of the filter box 1 via a hinge. Support frames 6 are fixedly installed on the left and right sides of the bottom of the filter box 1. An installation mechanism 2 is provided on the surface of the filter box 1. The installation mechanism 2 includes a motor 201 and driven bevel gears 204. The motor 201 is fixedly installed on the rear side of the filter box 1. Five driven bevel gears 204 are movably connected to the rear side of the filter box 1. A smooth rod 205 is fixedly installed on the front side of each of the five driven bevel gears 204. A double-ended screw 206 is fixedly installed on the front side of each of the five smooth rods 205. Screw blocks 207 are threadedly connected to the front and rear sides of the surfaces of the five double-ended screws 206. A plug rod 208 is fixedly installed on the right side of the screw block 207. A connecting rod 202 is fixedly connected to the output end of the machine 201. Each surface of the connecting rod 202 is fixedly equipped with a driving bevel gear 203. The surfaces of the five driving bevel gears 203 mesh with the surfaces of the five driven bevel gears 204. Slots 210 are provided on both the front and rear sides of the air guide pipe 7. Five filter bags 8 are inserted into the inner surface of the bottom of the air guide pipe 7, and all five filter bags 8 are interconnected with the air guide pipe 7. Insertion holes 9 are provided on both the front and rear sides of the surface of the filter bags 8. Insertion rod 208... All of them penetrate the inner cavity of the slot 210 and are inserted into the inner cavity of the socket 9. The inner cavities of the slot 210 and the socket 9 are in the same horizontal direction, and the inner cavities of the slot 210 and the socket 9 are interconnected. Limiting rods 209 are fixedly installed in the inner cavity of the filter box 1. The inner surface of the screw block 207 is slidably connected to the surface of the limiting rod 209. The surface of the connecting rod 202 is movably connected to the support plate 211 through the bearing. The front side of the four support plates 211 is fixedly installed on the rear side of the filter box 1.

[0031] By setting up the installation mechanism 2, the output of the motor 201 causes the driving bevel gear 203 and the driven bevel gear 204 to engage, and the bidirectional screw 206 drives the screw block 207 and the insert rod 208 to move inward, thereby connecting the insert rod 208 to the air guide tube 7 and the filter bag 8. This process makes the installation and removal of the filter bag 8 convenient, allowing for quick assembly and disassembly. It is also convenient for cleaning the filter bag 8 after prolonged use when its surface is covered with dust, making it easy for operators to use. The slot 210 allows for adjustment of the movement direction of the insert rod 208. The limit rod 209 is designed to prevent the insertion rod 208 from shifting during movement, thus affecting the accuracy of its insertion into the cavity of the insertion hole 9. The limit rod 209 also limits the movement of the screw block 207, preventing it from rotating synchronously with the bidirectional screw 206 and affecting the disassembly and assembly of the filter bag 8. The support plate 211 provides support for the connecting rod 202, preventing it from bending due to the weight of the active bevel gear 203 after prolonged use, which would affect the transmission of kinetic energy of the motor 201.

[0032] Example 2

[0033] like Figure 1 and Figure 2 As shown, in one embodiment, a flange 10 is fixedly installed on the left side of the air inlet 3. The surface of the flange 10 is provided with threaded grooves. Anchor bolts 11 are threadedly connected to the front and rear sides of the surfaces of the two support brackets 6. The bottom of the four anchor bolts 11 is threadedly connected to the ground.

[0034] By setting the flange 10, the air inlet 3 can be easily connected to the external pipeline, which facilitates the filter box 1 to filter different types of production equipment. By setting the anchor bolts 11, the equipment can be stabilized as a whole, avoiding accidental collisions due to external factors that could cause the equipment to tip over and affect the overall filtration effect of the equipment.

[0035] In operation, when the filter bag 8 needs to be disassembled and cleaned, the output of the motor 201 causes the connecting rod 202 to drive the active bevel gear 203 to rotate. At this time, the active bevel gear 203 and the driven bevel gear 204 cooperate, and the smooth rod 205 drives the bidirectional screw 206 to rotate synchronously. At this time, the screw block 207 drives the insertion rod 208 to move outward, so that the insertion rod 208 moves out of the inner cavity of the insertion hole 9. Then, the filter bag 8 is grasped and pulled downward to complete the disassembly of the filter bag 8. After completion, the filter bag 8 is reinserted into the inner surface of the air guide tube 7, so that the filter bag 8 and the air guide tube 7 are connected to each other. Then, through the reverse output of the motor 201, the connecting rod 202 drives the active bevel gear 203 to rotate in the opposite direction. At this time, the driven bevel gear 204 synchronously drives the smooth rod 205 and the bidirectional screw 206 to rotate in the opposite direction. At this time, the screw block 207 and the insertion rod 208 move inward, so that the filter bag 8 passes through the inner cavity of the slot 210 and is reinserted into the inner cavity of the insertion hole 9, thus completing the installation of the filter bag 8.

[0036] 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 person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all 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.
