Description

An online pulse jet bag filter Technical Field

[0001] This utility model relates to a pulse bag filter, specifically an online cleaning pulse bag filter, belonging to the technical field of pulse bag filters. Background Technology

[0002] Pulse jet baghouse dust collectors are an improved version of baghouse dust collectors, widely used in flue gas dust control. They are characterized by their small size, high efficiency, and large air volume handling capacity, and are applied in various industries. Pulse jet baghouse dust collectors suspend filter bags through a perforated tube sheet.

[0003] The filter bags are mainly fixed inside the tube sheet by a keel frame, and then the dust on the outside of the filter bags is cleaned by pulse valves and blow pipes.

[0004] When using a pulse jet bag filter for dust removal, after prolonged operation, dust that cannot be removed by the pulse valve will accumulate on the filter bags. Furthermore, the filter frame will deform after extended use. Therefore, it is necessary to clean the filter bags and repair or replace the filter frame. Currently, the common practice is to disassemble the pulse valve and blowpipe, and then use tools to pry up the filter bags and filter frame for disassembly. This process is not only cumbersome but also inconvenient for prying up the filter bags and filter frame. Summary of the Invention

[0005] The purpose of this invention is to provide an online pulse jet bag filter to solve the above problems. It can disassemble the filter bag without disassembling the pulse valve and blow pipe, and can also quickly remove the filter bag and the frame, thereby improving the disassembly efficiency of the filter bag.

[0006] This utility model achieves the above-mentioned objectives through the following technical solution: an online pulse jet baghouse dust collector includes a dust collector body. A disassembly structure is installed inside the dust collector body. The disassembly structure includes a fixing plate. The fixing plate is slidably connected to the top of the dust collector body. Multiple fixing slots are arranged in a rectangular array on the fixing plate. A filter bag is detachably connected to each fixing slot. A frame is detachably connected to each fixing slot. A top rod is slidably connected to the bottom of the fixing plate, and the top rod abuts against the filter bag. A bottom plate is fixedly connected inside the dust collector body, and the top rod abuts against the bottom plate. A fixing column is rotatably connected to the top of the fixing plate. A rotating plate is fixedly connected to the top of the fixing column. Multiple contact plates are fixedly connected to the rotating plate in a circular array, and the contact plates abut against the frame. A pulse valve is installed on the side of the dust collector body, and multiple jet pipes are fixedly connected to the pulse valve in a linear distribution.

[0007] Preferably, a limiting structure is installed on the fixing plate, the limiting structure includes a limiting plate, the limiting plate is slidably connected to the fixing column, the limiting plate and the fixing plate abut against each other, and a spring is fixedly connected between the limiting plate and the fixing plate.

[0008] Preferably, the limiting plate has a protrusion, and the fixing plate has a groove inside, and the protrusion and the groove engage.

[0009] Preferably, the protrusions are arranged in a ring array, and the grooves are arranged in a ring array.

[0010] Preferably, the protrusion has an overall arc-shaped structure, and the groove has an overall arc-shaped structure.

[0011] Preferably, a limiting sleeve is fixedly connected to the bottom end of the fixing plate, and the limiting sleeve and the top rod are slidably connected.

[0012] Preferably, a limiting ring is fixedly connected to the top rod, and the limiting ring abuts against the limiting sleeve and the fixing plate respectively.

[0013] Preferably, a guide rod is fixedly connected inside the dust collector body, and a guide groove is provided on the fixed plate, with the guide rod and the guide groove being slidably connected.

[0014] Preferably, a protective cover is fixedly connected inside the dust collector body, and an electric push rod is installed inside the protective cover. The output end of the electric push rod is fixedly connected to the fixed plate.

[0015] Preferably, the top of the protective cover is detachably connected to a mounting plate, and the mounting plate has an overall convex shape.

[0016] The beneficial effects of this utility model are as follows: rotating the rotating plate can drive multiple contact plates to rotate. When the contact plates and the keel frame are separated, activating the electric push rod can drive the fixed plate to slide downward. When the top rod and the bottom plate collide, the fixed plate continues to slide downward, thereby lifting the keel frame and the filter bag from the fixing groove on the fixed plate through the top rod. Therefore, the filter bag can be quickly removed for cleaning. At the same time, the filter bag can be cleaned without disassembling the pulse valve and the blow pipe. When using the dust collector body, the external gas that needs to be dusted enters from one side of the bottom of the dust collector body. The gas can be treated for dust removal through multiple filter bags. By activating the pulse valve, the filter bag can be cleaned through the blow pipe. Attached Figure Description

[0025] As a technical optimization of this utility model, a limiting structure 3 is installed on the fixing plate 201. The limiting structure 3 includes a limiting plate 301. The limiting plate 301 is slidably connected to the fixing post 207. The limiting plate 301 and the fixing plate 201 abut against each other. A spring 302 is fixedly connected between the limiting plate 301 and the fixing plate 201. By the contact between the limiting plate 301 sliding on the fixing post 207 and the fixing plate 201, and the elastic force of the spring 302, the contact plate 209 can be limited.

[0026] As a technical optimization of this utility model, the limiting plate 301 is provided with a protrusion 303, and the fixing plate 201 is provided with a groove 304. The protrusion 303 and the groove 304 are engaged. Multiple protrusions 303 are arranged in a ring array, and multiple grooves 304 are arranged in a ring array. The protrusion 303 and the groove 304 are both arc-shaped. Through the engagement of the protrusion 303 and the groove 304, the contact plate 209 can be fixed to prevent the contact plate 209 from rotating automatically on the fixing plate 201.

[0027] As a technical optimization of this utility model, a limiting sleeve 305 is fixedly connected to the bottom end of the fixing plate 201. The limiting sleeve 305 and the top rod 205 are slidably connected. A limiting ring 306 is fixedly connected to the top rod 205.

[0031] In use, when cleaning the filter bags 203 inside the dust collector body 1 is required, rotating the rotating plate 208 causes multiple contact plates 209 to rotate. After the contact plates 209 separate from the frame 204, activating the electric push rod 309 causes the fixing plate 201 to slide downwards. When the top rod 205 contacts the bottom plate 206, the fixing plate 201 continues to slide downwards, thereby lifting the frame 204 and filter bags 203 from the fixing grooves 202 on the fixing plate 201 via the top rod 205. This allows for quick removal and cleaning of the filter bags 203. Furthermore, the filter bags 203 can be cleaned without disassembling the pulse valve 4 and the blowpipe 5. When using the dust collector body 1, the gas requiring dust removal enters from one side of the bottom of the dust collector body 1, and the multiple filter bags 203 effectively remove dust from the gas. By activating the pulse valve 4, the filter bag 203 can be cleaned through the blow pipe 5. The contact plate 209 can be limited by the contact plate 301 sliding on the fixed column 207 and the contact plate 201, and the elastic force of the spring 302. The contact plate 209 can be fixed by the engagement of the protrusion 303 and the groove 304, preventing the contact plate 209 from rotating automatically on the fixed plate 201. The top rod 205 can be limited by the contact between the limit sleeve 305 and the limit ring 306 fixed on the top rod 205. The fixed plate 201 can be guided and limited by the sliding connection between the guide rod 307 and the guide groove 308. The position of the fixed plate 201 can be adjusted by the electric push rod 309. The electric push rod 309 can be protected by the protective cover 310. The electric push rod 309 can be easily inspected by the mounting plate 311.
