Description

Technical Field

[0001] This utility model relates to the field of rubber compound production and processing technology, specifically to a dust removal device for environmentally friendly rubber compound production. Background Technology

[0002] During the production of rubber compound, a large amount of carbon black dust and other dust are generated. This dust not only pollutes the working environment but also poses a serious threat to the health of operators. Currently, the baghouse dust collector structure commonly used in rubber compound production typically consists of several sets of filter bags supported and fixed on a tube sheet located above the housing. The blower pipes are located inside the housing above the tube sheet, and several sets of nozzles on the blower pipes correspond one-to-one with the openings of several sets of filter bags on the tube sheet. However, the openings at the top of the filter bags easily generate a large amount of dust when the filter bags are blown by the nozzles under the action of the electromagnetic pulse valve. After dispersing, some of this dust accumulates on the tube sheet. Traditional baghouse dust collector structures often cannot clean the dust accumulated on the tube sheet in a timely manner, affecting the dust removal effect. In addition, the large amount of dust accumulated on the tube sheet over a long period of time increases the difficulty and time required for subsequent disassembly, cleaning, and replacement of the filter bags. Furthermore, the dust generated during operation can also pose an unnecessary threat to the health of operators. Utility Model Content

[0003] The purpose of this utility model is to provide a dust removal device for environmentally friendly rubber compound production. Compared with the main body of a traditional bag filter, this dust removal device can effectively reduce the probability of dust accumulation on the tube sheet and the second tube sheet during long-term use. It facilitates subsequent cleaning and also effectively reduces the unnecessary impact caused by subsequent disassembly and replacement of the filter bags and their internal support frames. During operation, it is less likely to generate dust by cleaning the dust on the second tube sheet, thus avoiding unnecessary threats to the health of the operators. It further improves the speed of filter bag disassembly and assembly and the dust removal effect of this environmentally friendly rubber compound production dust removal device.

[0004] The technical solution adopted by this utility model to solve the above problems is:

[0005] A dust removal device for environmentally friendly rubber compound production includes a bag filter body, a dust collection box on the bag filter body, a dust removal component and a jet cleaning component on the dust collection box. The dust removal component includes a tube sheet inside the dust collection box, a second tube sheet installed above the tube sheet, several sets of filter bags supported and installed on the second tube sheet, and a bag support frame inside the filter bags. The second tube sheet has several sets of slots formed by multiple sets of horizontally and vertically arranged isolation strips around the opening at the top of the filter bags. The jet cleaning component includes an air storage tank installed on the dust collection box and a jet cleaning pipe connected to it above the tube sheet via multiple sets of electromagnetic pulse valves. The jet cleaning pipe has several sets of first and second jet nozzles respectively positioned above the opening at the top of the filter bags and the slots of the second tube sheet.

[0006] Preferably, the two side walls of the isolation strips corresponding to the plurality of slots are all set as inclined surfaces, and the plurality of second nozzles are arranged above the plurality of intersection points formed by the plurality of horizontally and vertically arranged isolation strips.

[0007] Preferably, the bag support frame includes several sets of connecting rods arranged in an array around the inner wall of the bag, and several sets of connecting rings arranged at intervals around the connecting rods for fixing the several sets of connecting rods, and connecting seats installed at the upper and lower ends of the several sets of connecting rods. The connecting seat located below the first nozzle and connected to the top of the several sets of connecting rods is funnel-shaped.

[0008] Preferably, the top of the dust collector is provided with an opening adapted to the size of the second tube sheet, and a top cover is detachably installed on the opening. The blowing pipe is detachably installed in the dust collector, and the second tube sheet located below the blowing pipe is detachably slidable in the dust collector by having multiple sets of spaced hanging rings arranged around its periphery.

[0009] Preferably, the dust collector is provided with a dust hopper at the bottom and a guide plate is rotatably provided on the dust outlet at the bottom of the dust hopper.

[0010] Compared with the prior art, this utility model has the following advantages and effects:

[0011] This utility model relates to an environmentally friendly dust removal device for rubber compound production. This dust removal device further improves the structure of the dust collection components and the jet cleaning components on the dust collection box of a traditional baghouse dust collector. The dust collection components feature an added structure of a second tube sheet on the tube sheet and several sets of crisscrossing isolation strips forming several sets of slots. Combined with several sets of first nozzles positioned on the top opening of the filter bags in the jet cleaning pipe of the jet cleaning component, this allows for the jet cleaning and filtration of dust adhering to the filter bags. Simultaneously, several sets of second nozzles positioned above the slots in the jet cleaning pipe perform a jet cleaning process on several sets of slots on the second tube sheet. This effectively reduces the probability of dust accumulation on the tube sheet and second tube sheet during long-term use, further improving the efficiency of the jet cleaning component. The improved blowing effect of the components and the dust removal effect of the dust removal components facilitate subsequent cleaning and effectively reduce unnecessary impacts from subsequent operations such as disassembly and replacement of the filter bags and their internal support frames. During operation, it is less likely to generate dust from cleaning the dust on the second tube sheet, thus avoiding unnecessary threats to the health of operators. Simultaneously, it allows several sets of slots on the second tube sheet to maintain a certain level of cleanliness, facilitating the lifting and separation of the filter bags and their internal support frames from the second mounting holes on the second tube sheet, and the disassembly, cleaning, and replacement of the filter bags and their internal support frames after insertion into the first mounting holes on the tube sheet. This further improves the convenience and efficiency of filter bag assembly and disassembly operations. Furthermore, the addition of the second tube sheet on the tube sheet also further enhances the support stability of the filter bags and their internal support frames. Attached Figure Description

Detailed Implementation

[0017] The present invention will now be described in detail with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0018] See Figure 1-4 This embodiment relates to a dust removal device for environmentally friendly rubber compound production, including a bag filter 23 dust collector body. A dust collection box 1 is mounted on the bag filter 23 dust collector body, and a dust removal assembly 2 and a jet cleaning assembly 3 are mounted on the dust collection box 1. The dust removal assembly 2 includes a tube sheet 21 disposed inside the dust collection box 1, a second tube sheet 22 mounted above the tube sheet 21, several sets of filter bags 23 supported on the second tube sheet 22 and installed through the tube sheet 21, and a bag support frame 24 disposed inside the filter bags 23. The second tube sheet... The bag 22 has several sets of slots 220 formed by multiple sets of horizontally and vertically arranged isolation strips 221 around the opening at the top of the bag 23. The blowing assembly 3 includes an air tank 31 installed on the dust collector 1 and a blowing pipe 33 connected to the top of the tube sheet 21 through multiple sets of electromagnetic pulse valves 32. The blowing pipe 33 has several sets of first nozzles 341 and second nozzles 342 respectively set above the opening at the top of the bag 23 and the slots 220 of the tube sheet 22.

[0019] Specifically in this embodiment, such as Figure 1 The dust removal equipment shown here for the production of environmentally friendly rubber compound combines the conventional structure of the main body of the existing bag filter 23 dust collector with an overall structural design. During operation, it can be combined with... Figure 2As shown, the external ventilation duct 4 is connected to the corresponding air inlet 11 and exhaust outlet 12 at the corresponding positions of the dust collection box 1. The fan 5 connected to the ventilation duct 4 connected to the exhaust outlet 12 allows external dust to be drawn into the dust collection box 1 through the air inlet 11. After dust removal, the dust is discharged through the exhaust outlet 12 and the ventilation duct 4 connected to it, and then through the exhaust duct 6 connected to the fan 5. The specific dust removal process is the same as the dust removal principle of the common bag filter 23 dust collector in the prior art. That is, the dust entering the dust collection box 1 through the air inlet 11 can be filtered by several sets of filter bags 23 installed on the tube sheet 21 inside the dust collection box 1 in the dust collection assembly 2 under the action of the fan 5. The filtered impurities can adhere to the filter bags 23. The gas filtered by the filter bag 23 can float above the tube sheet 21 through the bag support frame 24 inside the filter bag 23 and the opening at the top. It is then discharged through the exhaust port 12 and the exhaust pipe 6 connected to the ventilation pipe 4 and the fan 5. While the dust removal component 2 is performing dust removal, the jet cleaning component 3 is also working. The air storage tank 31 can be connected to an external air filling device through an air pipe for filling and emptying. In conjunction with the action of the electromagnetic pulse valve 32, pulse jets can be sprayed into the filter bag 23 through the jet pipe 33 and the nozzle 34 through the opening at the top of the filter bag 23. This causes the impurities attached to the filter bag 23 to fall to the bottom of the dust collection box 1 and be discharged through the ash outlet 140 at the bottom. At the same time, the generated The dust continues to be filtered repeatedly by the filter bag 23 before being discharged. Compared with the traditional filter bag 23 dust collector, this environmentally friendly dust removal equipment for rubber compound production adds a second tube sheet 22 above the tube sheet 21 in its dust removal component 2. The second tube sheet 22 can be adapted to the structure of the tube sheet 21 and cover it. In actual use, the filter bags 23 can be installed by passing through the first mounting hole 211 on the tube sheet 21 and the second mounting hole 222 on the tube sheet 22. At the same time, the bag opening at the top of the filter bag 23 and the ring on the bag opening can be fixed on the second tube sheet 22 by the groove 223 provided on the second mounting hole 222. When the bag support frame 24 is installed inside the filter bag 23, its top... The outer edge of the filter bag 23 can be abutted against the ring body, stabilizing the filter bag 23 and its internal support frame 24 on the second tube sheet 22 above the tube sheet 21. In actual use, the electromagnetic pulse valve 32 causes some of the dust generated when the gas is blown into the filter bag 23 through the blowing pipe 33 and the first nozzle 341 to accumulate in several sets of slots 220 formed by multiple sets of horizontally and vertically arranged isolation strips 221 on the second tube sheet 22. At the same time as the electromagnetic pulse valve 32 is activated, the dust accumulated in the slots 220 on the second tube sheet 22 can be blown away through the blowing pipe 33 and the second nozzle 342, allowing some of the dust to enter the filter bag 23 for filtration in conjunction with the blowing process of the first nozzle 341.Meanwhile, another part of the dust can be discharged externally through the exhaust port 12 and the ventilation pipe 6 under the action of the fan 5. In order to ensure the working stability of the fan 5 and the cleanliness of the discharged gas, dust removal filter elements such as filter screens 7 or filter cartridges can be installed inside the exhaust port 12 and the exhaust pipe 6 respectively. This environmentally friendly dust removal equipment for rubber compound production further improves the structure of the dust removal component 2 and the jet cleaning component 3 on the dust collection box 1 of the traditional bag filter 23 dust collector. The dust removal component 2 features an added structure of several sets of slots 220 formed by a second tube sheet 22 on the tube sheet 21 and multiple sets of horizontally and vertically arranged isolation strips 221. Combined with several sets of first nozzles 341 arranged on the top opening of the tube sheet 23 in the jet cleaning component 3, it can clean and filter the dust attached to the tube sheet 23 by jet cleaning. Simultaneously, the several sets of second nozzles 342 arranged above the slots 220 on the tube sheet 33 can perform a jet cleaning process on the slots 220 on the second tube sheet 22, effectively reducing the probability of dust accumulation on the tube sheet 21 and second tube sheet 22 during long-term use, further improving the jet cleaning effect of the jet cleaning component 3. The dust removal component 2 effectively reduces the impact of subsequent cleaning operations such as disassembly and replacement of the filter bag 23 and its internal support frame 24. During operation, it also minimizes dust generation from cleaning the second tube sheet 22, thus preventing unnecessary health threats to operators. Furthermore, it maintains a certain level of cleanliness in the slots 220 on the second tube sheet 22, facilitating the lifting and separation of the filter bag 23 and its internal support frame 24 through the second mounting holes 222 on the second tube sheet 22 and their insertion into the first mounting holes 211 on the tube sheet 21. This further improves the convenience and efficiency of filter bag assembly and disassembly operations. Moreover, the addition of the second tube sheet 22 on the tube sheet 21 further enhances the support stability of the filter bag 23 and its internal support frame 24.

[0020] The side walls of the isolation strips 221 corresponding to the plurality of slots 220 are all set as inclined surfaces. The plurality of second nozzles 342 are arranged above the plurality of intersection points formed by the plurality of horizontally and vertically arranged isolation strips 221. Specifically, from Figure 2-4As can be seen, the isolation strip 221 with this structure can further reduce the accumulation of dust on the top wall of the isolation strip 221, so that the dust can slide down the inclined walls on both sides of the isolation strip 221 into the slot 220. At the same time, combined with the arrangement of the second nozzle 342, the blowing effect of the second nozzle 342 can be further improved, so that the gas blown out can be guided and distributed to the multiple slots 220 formed around the intersection of the multiple sets of isolation strips 221. This can further expand the blowing range of the second nozzle 342, and the number of second nozzles 342 on the blowing pipe 33 can be appropriately reduced. At the same time, under the guidance of the inclined walls on both sides of the isolation strip 221, the dust accumulated inside the slot 220 can be blown down along the opening at the top of the cloth bag 23 in the middle of the slot 220. This further improves the blowing effect of the blowing assembly 3 and further reduces the phenomenon of dust accumulation on the second tube sheet 22.

[0021] The bag support frame 24 includes several sets of connecting rods 241 arranged in an array around the inner wall of the bag 23, and several sets of connecting rings 242 arranged at intervals around the connecting rods 241 for fixing the connecting rods 241. Connecting seats 243 are installed at the upper and lower ends of the connecting rods 241. The connecting seat 243, located below the first nozzle 341 and connected to the top of the connecting rods 241, is funnel-shaped. Figure 3 As can be seen, the bag support frame 24 adopts the bag support structure commonly used inside the filter bag 23 in the existing technology of the filter bag 23 dust collector. The connecting rod 241 can be welded and fixed to the connecting plate and the connecting seat 243. Based on the traditional bag support structure, the connecting seat 243 installed at the top of several sets of connecting rods 241 is set in a funnel shape, so that it can accumulate the gas sprayed by several sets of first nozzles 341 installed on the upper spray pipe 33. This improves the stability and effectiveness of the gas sprayed from the first nozzle 341 through the funnel-shaped connecting seat 243 into the filter bag 23. It also blocks the opening at the top of the filter bag 23 to a certain extent, effectively reducing the amount of dust below the tube sheet 21 that floats out through the opening at the top of the filter bag 23 and accumulates on the second tube sheet 22 during the dust removal process. This further improves the stability and efficiency of dust filtration and dust removal in the dust collector 1 through the filter bag 23.

[0022] The top of the dust collector 1 has an opening adapted to the size of the second perforated plate 22, and a top cover 13 is detachably installed on the opening. The blowing pipe 33 is detachably installed inside the dust collector 1, and the second perforated plate 22 located below the blowing pipe 33 is detachably slidable inside the dust collector 1 by having multiple sets of spaced hanging rings 224 arranged around its periphery. The opening on the top of the dust collector 1 adapted to the second perforated plate 22 is designed to connect with the top cover 13, which is detachably installed on it by bolts, further improving the dust collection efficiency inside the dust collector 1. The convenience of daily maintenance and subsequent upkeep of the jet-blowing assembly 3 and dust collection assembly 2, combined with the multiple sets of jet-blowing pipes 33 that are detachably connected by a plug-in method and the several sets of first jet-blowing nozzles 341 and second jet-blowing nozzles 342 on them, facilitates disassembly and separation within the dust collection box 1. Thus, after the jet-blowing pipes 33 are disassembled within the dust collection box 1, the hoisting ropes can be connected using external hoisting tools (such as electric hoists, cranes, etc.) on the multiple sets of spaced hanging rings 224 arranged around the second tube sheet 22. Thus, combined with the smooth structure of the inner wall of the dust collector 1 located above the tube sheet 21, during the hoisting process, the second tube sheet 22 can slide upwards along the inside of the dust collector 1 above the tube sheet 21. Simultaneously, combined with the connection method of the filter bags 23 and their supporting frames 24 to the second mounting holes 222 and their upper groove edges 223, several sets of filter bags 23 and their internal supporting frames 24 can follow the second tube sheet 22 upwards through the first mounting holes 211 on the tube sheet 21 until they slide out into the dust collector 1. Finally, combined with... The hoisting process of the hoisting tool allows the second tube sheet 22 and several sets of filter bags 23 and their internal support frames 24 to be disassembled and assembled on the tube sheet 21 of the dust collector box 1, and then placed on the maintenance platform or the ground for cleaning and replacement of the filter bags 23 and their internal support frames 24. This further improves the speed and efficiency of disassembling several sets of filter bags 23 and their internal support frames 24 in the dust collector box 1, further improves the convenience and efficiency of daily maintenance and later maintenance, and meets different maintenance needs.

[0023] The dust collector 1 has a dust hopper 14 at its bottom, and a guide plate 141 is rotatably mounted on the dust outlet 140 at the bottom of the dust hopper 14. The guide plate 141 is driven to rotate by a driving component 15 installed at the bottom of the dust hopper 14. Both the dust collector 1 and the dust hopper 14 have openings on their side walls, and each opening is covered with a cover plate 16. Specifically... Figure 5As can be seen, the structural design of the dust collector 1's bottom ash hopper 14, combined with the guide plate 141 driven to rotate by the drive component 15 on its bottom ash outlet 140, can further improve the stability and efficiency of dust collection and subsequent discharge inside the dust collector 1, meeting different emission requirements. At the same time, the cover plate 16, which is detachably connected to the opening on the side wall of the ash hopper 14 by bolts, facilitates the observation and cleaning of the ash accumulation inside the ash hopper 14. Furthermore, the cover plate 16, which is rotated and locked by hinges and locking bolts on the opening on the side wall of the dust collector 1, along with the multiple sets of handrails installed on the side wall of the dust collector 1, facilitates the observation and subsequent adjustment of the ash accumulation in the filter bags 23 inside the dust collector 1, improving the operational flexibility and stability of this environmentally friendly rubber compound production dust collection equipment.
