Description

Technical Field

[0001] This utility model relates to the field of dust removal technology in processing workshops, and more specifically, to a bag filter dust collector for equipment processing workshops. Background Technology

[0002] In equipment processing workshops, various mechanical processing processes such as cutting, grinding, and welding generate a large amount of dust. This dust not only contains metal shavings and sand particles, but may also contain chemical substances. If not treated, it will cause many hazards to the workshop environment and the health of personnel. On the one hand, the diffused dust reduces visibility in the workshop, which can easily lead to operational errors and safety accidents. On the other hand, long-term inhalation of dust can damage workers' respiratory tract and lungs. In addition, the random emission of dust can also pollute the surrounding atmospheric environment. Baghouse dust collectors have emerged to address this issue. With their high-efficiency dust removal capabilities, they create a clean and safe production space for the workshop.

[0003] Existing baghouse dust collectors used in processing workshops generate complex and diverse dust due to the characteristics of the processing technology. This makes it extremely easy for dust particles to adhere to the outer surface of the dust collector bags. Moreover, these particles have strong adhesion, and conventional cleaning methods are ineffective, making cleaning extremely difficult. Each dust removal operation is not only cumbersome but also requires machine shutdown, which undoubtedly increases downtime and seriously affects the production efficiency of the workshop. Therefore, improvements and optimizations are needed. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a bag dust collector for equipment processing workshops, which has the advantages of precise automatic control.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bag filter dust collector for a processing workshop, comprising a dust collection box, an annular groove on the inner side of the dust collection box, a supporting plate slidably mounted on the inner side of the annular groove, a fixing plate fixedly sleeved on the inner wall of the dust collection box and flush with the bottom side of the annular groove, a spring fixedly connected between the fixing plate and the supporting plate in a circumferential array, a first electrical connection device fixedly mounted on the left and right sides of the inner side of the supporting plate, a second electrical connection device fixedly mounted on the left and right sides of the bottom side of the annular groove and corresponding to the first electrical connection device, and a circular groove on the outer surface of the supporting plate in a circumferential array. The dust collector is arranged in an array. A bag support is fixedly installed inside the circular groove, and a dust collector bag is snapped into the inside of the bag support. Multiple fixed supports are fixedly installed on the inner wall of the dust collector, and the fixed supports are located above the support plate. An annular connecting pipe is fixedly connected to the inner side of the fixed support. Multiple first connecting pipes are fixedly connected to the outer surface of the annular connecting pipe, and the first connecting pipes extend to the inner side of the dust collector bag. Air jets are fixedly installed on the outer surface of the first connecting pipes, and the air jets are arranged in a linear array on the outer surface of the first connecting pipes. An air jetting mechanism is fixedly installed at the top of the dust collector. The air jetting mechanism and the annular connecting pipe are connected through a conveying pipe. A dust discharge mechanism is fixedly installed on the inner wall of the dust collector.

[0006] As a preferred embodiment of this utility model, the dust removal mechanism includes an annular bracket fixedly installed on the inner wall of the dust collector, and the annular bracket is located directly below the bag support. Multiple branch pipes are fixedly connected to the inner side of the annular bracket, and the ends of the branch pipes are fixedly connected to and communicate with the conversion connectors. Dust discharge ports are opened on the lower outer surface of the branch pipes in a linear array. An outer pipe is fixedly connected to the outer surface of the dust collector, and the outer pipe extends through the dust collector and the annular bracket to the inner side of the conversion connector and communicates with it.

[0007] As a preferred technical solution of this utility model, the jet mechanism includes an air compressor fixedly installed on the top of the dust collection box, and the air compressor has extension pipes on the left and right sides. The ends of the air compressor extension pipes are fixedly connected to fans and are interconnected. The fans and the annular connecting pipe are interconnected through a conveying pipe. The bottom of the dust collection box is fixedly installed with a connecting component, and the connecting component is conical in shape.

[0008] As a preferred embodiment of this utility model, a dust collection box is fixedly installed at the bottom of the connecting component, and the dust collection box is interconnected with the connecting component and is rectangular in shape.

[0009] As a preferred embodiment of this utility model, the bottom of the dust collection box is fixedly connected to a discharge pipe and the discharge pipe is interconnected with the dust collection box, and a valve is threadedly connected inside the discharge pipe.

[0010] As a preferred embodiment of this utility model, the fixing plate is annular in shape and does not contact the bag support and the dust collector bag.

[0011] As a preferred embodiment of this utility model, the outer surface of the bag support is hollowed out and the bottom is sealed.

[0012] As a preferred technical solution of this utility model, a fixing frame is fixedly sleeved on the outer surface of the dust collection box and located below the outer pipe, and multiple bases are fixedly installed on the bottom side of the outer pipe.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. In this invention, as the dust collector bag passes through its outer surface, the weight of the bag gradually increases, causing the spring to elastically deform. This causes the supporting plate to gradually sink. When it sinks to a certain point, the first and second electrical connection devices will contact each other. At this point, the controller will activate the jet mechanism, which will then transmit the gas through the conveying pipe to the annular connecting pipe, and then from the annular connecting pipe to the first connecting pipe. Finally, the gas is sprayed onto the outer surface of the dust collector bag by the linearly arrayed jet nozzles, causing the dust particles to be blown off. Simultaneously, the weight of the dust collector bag decreases, allowing the spring to elastically release the gas. The force-restoring action allows the support plate to return to its original position, and the elastic deformation of the spring is within the acceptable range. Compared with traditional devices, when the dust removal mechanism sprays dust-laden gas into the dust collection box, the dust particles are adsorbed onto the outer surface of the dust collection bag, increasing its weight. This causes the spring to deform elastically, driving the support plate to sink. This triggers the controller to open the jet mechanism. The gas is transmitted to the first connecting pipe through the conveying pipe and the annular connecting pipe, and then sprayed onto the dust collection bag by the linearly arranged jet nozzles, blowing off the dust. After the dust collection bag loses weight, it returns to its original position by the elastic force of the spring. This design cleverly utilizes mechanical linkage and elasticity principles, achieving precise self-control, high-efficiency dust removal, and ensuring stable operation of the equipment while reducing manual intervention.

[0015] 2. This utility model connects to an external dust collection device via an external pipe. The dust-laden gas is then conveyed through the external pipe to the inside of the conversion connector, and then distributed to multiple branch pipes through the conversion connector. The branch pipes then discharge the dust-laden gas downwards through a linear array of dust discharge ports, gradually rising slowly from bottom to top. This prevents the dust discharge ports from being blocked by dust particles blown down by the jet mechanism. Compared to traditional devices, this device first smoothly guides the gas into the inside of the conversion connector through the external pipe, then precisely distributes it to multiple branch pipes, and finally steadily discharges it downwards through a linear array of dust discharge ports. The dust-laden gas thus slowly rises from bottom to top, ensuring uniform dispersion and improving purification efficiency. On the other hand, it effectively avoids backflow of dust blown down by the jet mechanism, preventing blockage of the dust discharge ports and ensuring continuous and stable operation of the system.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1 to 6As shown, this utility model provides a bag filter dust collector for a processing workshop, including a dust collection box 1. An annular groove 2 is formed on the inner side of the dust collection box 1. A support plate 3 is slidably installed inside the annular groove 2. A fixing plate 5 is fixedly sleeved on the inner wall of the dust collection box 1 and is flush with the bottom side of the annular groove 2. A spring 6 is fixedly connected between the fixing plate 5 and the support plate 3, and the spring 6 is arranged in a circumferential array. A first electrical connection device 4 is fixedly installed on the left and right sides of the inner side of the support plate 3. A second electrical connection device 7 is fixedly installed on the left and right sides of the bottom side of the annular groove 2 and corresponds to the first electrical connection device 4. A circular groove 10 is formed on the outer surface of the support plate 3, and the circular groove 10 is arranged in a circumferential array. A bag support 8 is fixedly installed on the side, and a dust collector bag 9 is snapped into the inside of the bag support 8. Multiple fixed supports 11 are fixedly installed on the inner wall of the dust collector box 1, and the fixed supports 11 are located above the support plate 3. An annular connecting pipe 12 is fixedly connected to the inner side of the fixed support 11. Multiple first connecting pipes 13 are fixedly connected to the outer surface of the annular connecting pipe 12, and the first connecting pipes 13 extend to the inner side of the dust collector bag 9. An air jet head 14 is fixedly installed on the outer surface of the first connecting pipe 13, and the air jet head 14 is arranged in a linear array on the outer surface of the first connecting pipe 13. An air jet mechanism is fixedly installed on the top of the dust collector box 1. The air jet mechanism and the annular connecting pipe 12 are connected through a conveying pipe 17. A dust discharge mechanism is fixedly installed on the inner wall of the dust collector box 1.

[0025] As the dust removal mechanism gradually sprays dust into the dust collection box 1, the dust-laden particles gradually adhere to the outer surface of the dust collection bags 9. As the dust-laden particles gradually adhere to the outer surface of multiple dust collection bags 9, the weight of the dust collection bags 9 gradually increases, causing the spring 6 to undergo elastic deformation. This causes the support plate 3 to gradually sink. When it sinks to a certain point, the first electrical connection device 4 and the second electrical connection device 7 will come into contact. At this time, the controller will start the jet mechanism, and the gas will be transmitted through the conveying pipe 17 to the annular connecting pipe 12, and then from the annular connecting pipe 12 to the first connecting pipe 13. Afterward, the gas is sprayed onto the outer surface of the dust collection bags 9 by the jet nozzles 14 arranged in a linear array, causing the dust-laden particles to be blown off. At the same time, the weight of the dust collection bags 9 becomes lighter, and the support plate 3 returns to its original position through the elastic force of the spring 6. The elastic deformation of the spring 6 is within the acceptable range.

[0026] As the dust collector bag 9 passes over its outer surface, its weight gradually increases, causing the spring 6 to deform elastically. This causes the support plate 3 to gradually sink. When it sinks to a certain point, the first electrical connection device 4 and the second electrical connection device 7 will come into contact. At this point, the controller will activate the jet mechanism, which will then transmit the gas through the conveying pipe 17 to the annular connecting pipe 12, and then from the annular connecting pipe 12 to the first connecting pipe 13. Finally, the linearly arrayed jet nozzles 14 will spray the gas onto the outer surface of the dust collector bag 9, causing the dust particles to be blown off. As the weight of the dust collector bag 9 decreases, it will recover its elasticity through the spring 6. The reaction causes the support plate 3 to return to its original position, and the elastic deformation of the spring 6 is within the acceptable range. Compared with traditional devices, when the dust removal mechanism sprays dust-laden gas into the dust collection box 1, the dust particles are adsorbed onto the outer surface of the dust collection bag 9, increasing its weight. This causes the elastic deformation of the spring 6 to drive the support plate 3 to sink, triggering the controller to open the jet mechanism. The gas is transmitted to the first connecting pipe 13 through the conveying pipe 17 and the annular connecting pipe 12, and then sprayed onto the dust collection bag 9 by the linearly arranged jet nozzles 14, blowing off the dust. After the dust collection bag 9 loses weight, it returns to its original position by the elastic force of the spring 6. This design cleverly utilizes the mechanical linkage and elastic principle, achieving precise self-control, high-efficiency dust removal, and ensuring stable operation of the equipment while reducing manual intervention.

[0027] The dust removal mechanism includes an annular bracket (18) fixedly installed on the inner wall of the dust collector 1, and the annular bracket 18 is located directly below the bag support 8. Multiple branch pipes 19 are fixedly connected to the inner side of the annular bracket 18. The ends of the branch pipes 19 are fixedly connected to a conversion connector 20 and communicate with each other. The lower outer surface of the branch pipes 19 is provided with a dust discharge port 21 in a linear array. An outer pipe 22 is fixedly connected to the outer surface of the dust collector 1 and extends through the dust collector 1 and the annular bracket 18 to the inner side of the conversion connector 20 and communicate with it.

[0028] When the outer pipe 22 is connected to the outer dust collection device, the dust-laden gas will be transmitted through the outer pipe 22 to the inside of the conversion connector 20, and then transmitted through the conversion connector 20 to multiple branch pipes 19. The branch pipes 19 then discharge the dust-laden gas downward through the dust discharge ports 21 arranged in a linear array, gradually rising slowly from bottom to top to prevent the dust discharge ports 21 from being blocked by dust particles blown off by the jet mechanism.

[0029] The external pipe 22 connects to the external dust collection device, and the dust-laden gas is then conveyed through the external pipe 22 to the inside of the conversion connector 20. After that, it is conveyed through the conversion connector 20 to multiple branch pipes 19, and then the dust-laden gas is discharged downward through the dust discharge ports 21 arranged in a linear array. The gas gradually rises slowly from bottom to top, preventing the dust discharge ports 21 from being blocked by dust particles blown down by the jet mechanism. Compared with traditional devices, this device first smoothly guides the gas into the inside of the conversion connector 20 through the external pipe 22, and then it is precisely distributed to multiple branch pipes 19. Finally, it is steadily discharged downward through the dust discharge ports 21 arranged in a linear array. The dust-laden gas thus slowly rises from bottom to top, which on the one hand ensures that the gas is evenly dispersed and treated, improving the purification efficiency; on the other hand, it effectively avoids the backflow of dust blown down by the jet mechanism and blockage of the dust discharge ports 21, ensuring the continuous and stable operation of the system.

[0030] The jetting mechanism includes an air compressor 15 fixedly installed on the top of the dust collection box 1, and the air compressor 15 has extension pipes on the left and right sides. The ends of the extension pipes of the air compressor 15 are fixedly connected to a fan 16 and are interconnected. The fan 16 and the annular connecting pipe 12 are interconnected through a conveying pipe 17. A connecting component 23 is fixedly installed at the bottom of the dust collection box 1, and the connecting component 23 is conical in shape.

[0031] A connecting component 23 is fixedly installed at the bottom of the dust collection box 1. The connecting component 23 is conical in shape, which can effectively collect the falling dust particles and prevent them from remaining inside the dust collection box 1. The air compressor 15 compresses the air into a high-speed airflow.

[0032] The bottom of the connecting component 23 is fixedly equipped with a dust collection box 24, and the dust collection box 24 is connected to the connecting component 23 and is rectangular in shape.

[0033] By connecting the dust collection box 24 and the connecting component 23, and by making the dust collection box 24 rectangular, dust particles can be effectively collected, preventing dust particles from scattering everywhere.

[0034] The dust collection box 24 is fixedly connected to the bottom of the discharge pipe 25 and the discharge pipe 25 is connected to the dust collection box 24. The discharge pipe 25 is threadedly connected to the valve 26.

[0035] The valve 26 is connected to the internal thread of the discharge pipe 25, which makes it easier to open and close the discharge pipe 25, thereby removing dust particles from the dust collection box 24.

[0036] The fixing plate 5 is ring-shaped and does not contact the bag support 8 or the dust collector bag 9.

[0037] The ring-shaped fixing plate 5 effectively supports the spring 6, preventing the bearing plate 3 from falling unevenly due to insufficient support.

[0038] Among them, the outer surface of the bag support 8 is hollow, and the bottom is sealed.

[0039] The outer surface of the bag support 8 is hollowed out and the bottom is sealed, which can effectively provide support and shape for the dust collector bag 9.

[0040] The outer surface of the dust collector 1 is fixedly fitted with a fixing frame 27 located below the outer pipe 22, and multiple bases 28 are fixedly installed on the bottom side of the outer pipe 22.

[0041] Multiple bases 28 are fixedly installed on the bottom side of the external pipe 22, which can effectively provide stable support for the entire device and avoid being easily affected by external physical factors.

[0042] Working principle and usage process of this utility model:

[0043] As the dust removal mechanism gradually sprays dust into the dust collection box 1, the dust-laden particles gradually adhere to the outer surface of the dust collection bags 9. As the dust-laden particles gradually adhere to the outer surface of multiple dust collection bags 9, the weight of the dust collection bags 9 gradually increases, causing the spring 6 to undergo elastic deformation. This causes the support plate 3 to gradually sink. When it sinks to a certain point, the first electrical connection device 4 and the second electrical connection device 7 will come into contact. At this time, the controller will start the jet mechanism, and the gas will be transmitted through the conveying pipe 17 to the annular connecting pipe 12, and then from the annular connecting pipe 12 to the first connecting pipe 13. Afterward, the gas is sprayed onto the outer surface of the dust collection bags 9 by the jet nozzles 14 arranged in a linear array, causing the dust-laden particles to be blown off. At the same time, the weight of the dust collection bags 9 becomes lighter, and the support plate 3 returns to its original position through the elastic force of the spring 6. The elastic deformation of the spring 6 is within the acceptable range.

[0044] When the outer pipe 22 is connected to the outer dust collection device, the dust-laden gas will be transmitted through the outer pipe 22 to the inside of the conversion connector 20, and then transmitted through the conversion connector 20 to multiple branch pipes 19. The branch pipes 19 then discharge the dust-laden gas downward through the dust discharge ports 21 arranged in a linear array, gradually rising slowly from bottom to top to prevent the dust discharge ports 21 from being blocked by dust particles blown off by the jet mechanism.
