Description

Technical Field

[0001] This utility model relates to the field of dust removal technology, and in particular to a modular combined bag filter dust removal system. Background Technology

[0002] The existing Chinese patent application number 202323406311.1 discloses a dust removal system for a small pulse bag filter, including an outer shell and an air outlet located at the upper outer side of the outer shell, and an air inlet located at the lower outer side of the outer shell. A dust funnel is fixedly installed at the lower end of the outer shell. A dust removal mechanism is provided inside and outside the upper end of the outer shell. A sealing partition is fixedly installed at the upper inner end of the outer shell. The sealing partition has several equally spaced through holes. Several equally spaced filter bag frames are installed on the lower surface of the sealing partition. A filter bag is fixedly fitted onto the outer surface of each filter bag frame. A dust removal component is provided on the outer side of the filter bag. A support leg is fixedly installed on the outer side of the dust funnel. A dust outlet is provided at the lower end of the dust funnel.

[0003] The aforementioned technology, which cleans the filter bag surface by installing a lead screw on the outside of the bag and using the lead screw to drive the cleaning components, achieves a certain degree of cleaning effect. However, in actual use, the lead screw and other components are constantly exposed to a dusty and harsh environment, which easily damages the lubrication measures on the lead screw. This leads to frequent shutdowns for maintenance, thus affecting the efficiency of the bag filter. Therefore, to solve the above-mentioned technical defects, we propose a modular combined bag filter cleaning system. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a modular combined bag filter dust removal system.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A modular combined bag filter dust collector cleaning system includes a casing containing the main body of the bag filter. An inner moving seat and an outer moving seat are respectively provided on the inner and outer sides of one side wall of the casing. A matching magnetic suction plate is provided between the inner and outer moving seats. A cleaning ring is fitted onto the outer ring of the filter bag inside the casing. The cleaning ring is connected to the inner moving seat via a mounting bracket. A pneumatic assembly is provided on the rear side of the casing, and the output end of the pneumatic assembly is connected to the outer moving seat. A connecting cylinder is provided at the upper end of the casing. One end of the connecting cylinder is connected to a pump. Several dust blowing pipes and drive pipes are provided on the outer ring of the connecting cylinder. The dust blowing pipes are connected to the interior of the casing, and the other end of the drive pipes is connected to an adjacent pneumatic assembly.

[0007] Preferably, the pneumatic assembly includes a mounting cylinder, a drive rod, and a tension spring. The mounting cylinder is mounted on the side of the housing. The upper end of the drive rod is slidably disposed inside the mounting cylinder. The lower end of the drive rod is connected to an adjacent external moving seat. The tension spring is located inside the mounting cylinder and its upper end is connected to the mounting cylinder through a connecting bracket. The lower end of the tension spring is connected to the drive rod. The end of the drive tube away from the communicating cylinder is connected to the mounting cylinder.

[0008] Preferably, the outer circumference of the connecting cylinder is provided with several quick connectors, and the connecting cylinder is connected to the dust blowing pipe and the drive pipe through the quick connectors.

[0009] Preferably, a pressure relief pipe is installed on the body of the drive pipe, and the bodies of the dust blowing pipe, the drive pipe, and the pressure relief pipe are all equipped with regulating valves.

[0010] Preferably, the inner wall of the housing is provided with several sets of limiting blocks, and each set of limiting blocks is located at both ends of the stroke of the inner moving seat.

[0011] Preferably, a guide rod is slidably provided at the end of the mounting bracket away from the inner moving seat, and the upper end of the guide rod is connected to the inner wall of the housing.

[0012] Preferably, the outer side of the housing is provided with a protective cover corresponding to the external moving seat, and the cover is a transparent cover.

[0013] The modular combined bag filter dust collector cleaning system proposed in this utility model has the following advantages:

[0014] 1. In this utility model, the components cooperate with each other so that the components located in the harsh environment inside the casing do not have any precision transmission parts, but are only simple mechanical parts. This not only makes each component more adaptable to the harsh environment inside the casing, but also significantly reduces the frequency of damage and the time and cost of replacement. At the same time, since each pneumatic component is relatively independent, the failure of one pneumatic component will not affect the normal operation of other components. Thus, this solution reduces the cost of use and facilitates the convenience of installation and replacement through modular design.

[0015] 2: In this utility model, the pneumatic components are designed so that the pump can supply or extract gas into the mounting cylinder, thereby controlling the extension or retraction of the drive rod through the inflow and outflow of gas, thus realizing the movement of the outer moving seat. At the same time, the quick connector allows for convenient replacement and disassembly of the pneumatic components when they are damaged, as well as control of their independent movement. The pressure relief pipe allows the gas inside the mounting cylinder to be easily released when the drive rod retracts. The limit block not only restricts the movement of the inner moving seat, but also prevents it from colliding with the end of its stroke, causing the inner moving seat to drive the mounting frame to vibrate. This vibration force can accelerate the cleaning of dust on the cleaning ring and the cloth bag. Attached Figure Description

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1

[0025] Reference Figure 1-6 A modular combined bag filter dust collector cleaning system includes a housing 1 containing the main body of the bag filter. An inner moving seat 2 and an outer moving seat 3 are respectively provided on the inner and outer sides of one side wall of the housing 1. A magnetic suction plate 5 is provided between the inner moving seat 2 and the outer moving seat 3. A cleaning ring 6 is fitted onto the outer ring surface of the filter bag inside the housing 1. The cleaning ring 6 is connected to the inner moving seat 2 via a mounting bracket 7. A pneumatic assembly is provided on the rear side of the housing 1. The output end of the pneumatic assembly is connected to the outer moving seat 3. A connecting cylinder 8 is provided at the upper end of the housing 1. A pump 9 is connected to one end of the connecting cylinder 8. Several dust blowing pipes 10 and drive pipes 11 are provided on the outer ring surface of the connecting cylinder 8. The dust blowing pipes 10 are connected to the interior of the housing 1, and the other end of the drive pipes 11 is connected to the adjacent pneumatic assembly.

[0026] Example 2

[0027] Reference Figure 1-6 While all other parts are the same as in Example 1, the difference between this example and Example 1 is as follows:

[0028] The pneumatic assembly includes a mounting cylinder 12, a drive rod 13, and a tension spring 14. The mounting cylinder 12 is mounted on the side of the housing 1. The upper end of the drive rod 13 is slidably disposed inside the mounting cylinder 12, and the lower end of the drive rod 13 is connected to the adjacent outer moving seat 3. The tension spring 14 is located inside the mounting cylinder 12, and its upper end is connected to the mounting cylinder 12 through a connecting bracket. The lower end of the tension spring 14 is connected to the drive rod 13. The end of the drive tube 11 away from the connecting cylinder 8 is connected to the mounting cylinder 12. The outer ring surface of the connecting cylinder 8 is provided with several quick connectors 15. The connecting cylinder 8 is connected to the dust blowing pipe 10 and the drive tube 11 through the quick connectors 15. With the pneumatic assembly, the pump 9 can deliver or extract gas into the mounting cylinder 12, thereby controlling the extension or retraction of the drive rod 13 through the inflow and outflow of gas, thus realizing the movement of the outer moving seat 3. At the same time, the quick connectors 15 make it convenient to replace or disassemble the pneumatic assembly when it is damaged, and to control its independent movement.

[0029] A pressure relief pipe 16 is installed on the body of the drive pipe 11. The bodies of the dust blowing pipe 10, drive pipe 11, and pressure relief pipe 16 are all equipped with regulating valves. The pressure relief pipe 16 allows the gas inside the mounting cylinder 12 to be easily released when the drive rod 13 retracts. Several sets of limiting blocks 17 are provided on the inner wall of the housing 1. Each set of limiting blocks 17 is located at both ends of the stroke of the inner moving seat 2. The limiting blocks 17 not only restrict the movement of the inner moving seat 2 but also prevent collision when the inner moving seat 2 reaches the end of its stroke, thereby preventing the inner moving seat... 2. The mounting bracket 7 vibrates, and this vibration can accelerate the cleaning of dust on the cleaning ring 6 and the cloth bag. A guide rod is slidably provided at the end of the mounting bracket 7 away from the inner moving seat 2. The upper end of the guide rod is connected to the inner wall of the housing 1. The setting of the guide rod improves the stability of the mounting bracket 7 when it moves. A protective cover 4 is provided on the outer side of the housing 1 corresponding to the outer moving seat 3. The cover 4 is a transparent cover. The setting of the protective cover 4 can not only play a certain role in preventing dust from the outer moving seat 3, but also prevent personnel from being injured by touching the moving outer moving seat 3.

[0030] Operating principle and advantages: In the process of using this utility model, each mounting bracket 7 is fitted onto the outside of the bag filter inside the housing 1 via the cleaning ring 6. When the bag needs to be cleaned after a long period of use, high-pressure gas is pumped into the connecting cylinder 8 by the pump 9. Part of this gas enters the upper part of the housing 1 through the dust blowing pipe 10, and then enters the bag, thereby having a backflushing effect on the bag and thus cleaning the bag to a certain extent. At the same time, another part of the high-pressure gas inside the connecting cylinder 8 enters the mounting cylinder 12 through the drive pipe 11. Under the push of the gas, the drive rod 13 extends downward quickly. Since the end of the drive rod 13 is connected to the outer moving seat 3, the drive rod 13 drives the inner moving seat 2 to move synchronously through the cooperation of the outer moving seat 3 and the magnetic suction plate 5, thereby driving the cleaning ring 5 to move downward.

[0031] Furthermore, in the above process, when the drive rod 13 moves to the end of its stroke, the valve is controlled to disconnect the drive pipe 11 from the connecting cylinder 8, while the pressure relief pipe 16 is unobstructed. That is, the high-pressure gas inside the mounting cylinder 12 flows through the drive pipe 11 to the pressure relief pipe 16 and finally flows out from the pressure relief pipe 16. As the high-pressure gas inside the mounting cylinder 12 flows out rapidly, the tension spring 14, which is stretched by the extension of the drive rod 13, continuously retracts. That is, the tension spring 14 drives the drive rod 13 to retract into the mounting cylinder 12, thereby driving the inner moving seat 2 to move upward.

[0032] In summary, this solution, through the cooperation of various components, ensures that the components located in the harsh environment inside the housing 1 do not have any precision transmission parts, but are only simple mechanical parts. This not only allows each component to adapt well to the harsh environment inside the housing 1, but also significantly reduces the frequency of damage and the time and cost of replacement, even if they are damaged. At the same time, because the pneumatic components are relatively independent of each other, the failure of one pneumatic component will not affect the normal operation of other components. Thus, this solution, through its modular design, reduces the cost of use on the one hand, and facilitates the convenience of installation and replacement on the other.

[0033] Furthermore, the pneumatic components are designed such that pump 9 can supply or extract gas into or out of the mounting cylinder 12, thereby controlling the extension or retraction of drive rod 13 through the inflow and outflow of gas, thus enabling the movement of outer moving seat 3. The quick-connect coupling 15 allows for convenient replacement and disassembly of the pneumatic components when damaged, as well as control of their independent movement. The pressure relief pipe 16 allows for easy gas release from the mounting cylinder 12 when drive rod 13 retracts. The limiting block 17 not only restricts the movement of inner moving seat 2 but also prevents it from colliding with the end of its stroke, causing the inner moving seat 2 to vibrate the mounting frame 7. This vibration accelerates the cleaning of dust on the cleaning ring 6 and the cloth bag. The guide rod enhances the stability of the mounting frame 7 during movement. The protective cover 4 not only provides a certain degree of dust protection for outer moving seat 3 but also prevents personnel from being injured by contact with the moving outer moving seat 3.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
