Description

Technical Field

[0001] This utility model relates to the technical field of baghouse dust collectors, specifically to a compartmentalized pulse cleaning linkage mechanism for a baghouse dust collector. Background Technology

[0002] Baghouse dust collectors are a type of high-efficiency air purification equipment widely used in industrial production processes. They capture solid particles in the air through filter bags, thereby purifying the gas. When the compartments become clogged, a dust removal mechanism is often required.

[0003] The existing dust removal linkage mechanism blows air from the inside to the outside of the filter bag through a pulse air head fixed above the compartment, causing the dust attached to the outer surface of the filter bag to be blown off. However, most filter bags are relatively long, and the pulse air head is located at the top of the filter bag, which causes the blown air to gradually weaken as it moves along the filter bag, making it difficult to clean the dust at the bottom of the filter bag.

[0004] The aforementioned dust removal linkage mechanism suffers from a certain distance between the pulse air blowing head and the bottom of the filter bag, making it difficult to clean the dust at the bottom of the filter bag, thus reducing the effectiveness of the device. Utility Model Content

[0005] This utility model proposes a compartmentalized pulse cleaning linkage mechanism for a bag filter, which solves the problem in the prior art where the pulse blowing head is a certain distance from the bottom of the filter bag, making it difficult to clean the dust at the bottom of the filter bag.

[0006] The technical solution of this utility model is as follows: A compartmentalized pulse cleaning linkage mechanism for a bag filter, including a mounting plate, and further comprising:

[0007] The connecting ring is slidably connected to the mounting plate. A blocking rod passes through the inside of the connecting ring. One end of the blocking rod passes through the connecting ring and into the mounting plate. The pulse blowing head is installed at the top of the blocking rod. The blocking plate is installed on the outer surface of the blocking rod. A connecting frame is sleeved on the outer surface of the blocking rod. A first transmission rod is rotatably connected inside the connecting frame. A fan blade is installed on the outer surface of the first transmission rod. The fixing frame is installed on the lower surface of the connecting frame. A breathable sheet is installed on the inner side of the fixing frame. The bottom end of the first transmission rod is rotatably connected to the inside of the breathable sheet. A cloth bag is installed on the lower surface of the connecting ring. An auxiliary cleaning mechanism is set on the lower surface of the breathable sheet.

[0008] As a preferred embodiment of the bag filter compartment pulse cleaning linkage mechanism of this utility model, in order to facilitate the reciprocating screw to drive the moving tube to reciprocate, the auxiliary cleaning mechanism includes a mounting frame, a reciprocating screw, a moving tube and a limiting block. The mounting frame is installed on the lower surface of the air vent plate, the reciprocating screw is rotatably connected in the mounting frame, the moving tube is set on the outer surface of the reciprocating screw through a screw nut, and the limiting block is slidably connected in the mounting frame through a connecting groove.

[0009] As a preferred embodiment of the bag filter compartment pulse cleaning linkage mechanism of this utility model, in order to enable the fan blades to drive the reciprocating screw to rotate, the front of the limiting block is installed on the outer surface of the moving tube, and the top of the reciprocating screw is installed on the bottom of the first transmission rod.

[0010] As a preferred embodiment of the bag filter compartment pulse cleaning linkage mechanism of this utility model, in order to facilitate the cleaning of the lower layer of the filter bag, the limiting block is internally rotatably connected to a second transmission rod, and a cleaning plate is installed on the outer surface of the second transmission rod.

[0011] As a preferred embodiment of the bag filter compartment pulse cleaning linkage mechanism of this utility model, in order for the transmission gear to better drive the second transmission rod to rotate, a transmission gear is installed on the outer surface of the second transmission rod, and a rack is installed on the outer side of the mounting bracket.

[0012] As a preferred embodiment of the compartment pulse cleaning linkage mechanism of the bag filter of this utility model, in order to clean both sides of the lower layer of the filter bag, the transmission gear meshes with the rack, and the number of the cleaning plate, the second transmission rod, the transmission gear and the rack are all two sets.

[0013] The working principle and beneficial effects of this utility model are as follows:

[0014] In this invention, the transmission gear moves along the rack, causing the transmission gear to drive the second transmission rod to rotate. The cleaning blade cleans the lower layer of the cloth bag. Compared with the direct pulse blowing of the prior art, this device can be linked with pulse blowing to clean the cloth bag in a coordinated manner, thus improving the cleaning effect of the device.

[0015] In this invention, gas is delivered into the bag via a pulse blowing head, causing the fan blades to drive the first transmission rod to rotate. Compared to the prior art of blowing air directly from the top of the bag, this device enables the first transmission rod to transfer kinetic energy downwards, allowing the first transmission rod and the reciprocating screw to work together to clean the bag and reduce the impact of the gradually weakening wind force on normal dust removal during the downward movement of the gas.

Detailed Implementation

[0022] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0023] like Figures 1-4 As shown, this embodiment proposes a compartment pulse cleaning linkage mechanism for a bag filter, including a mounting plate 1, a connecting ring 2, a blocking rod 3, a pulse blowing head 4, a blocking plate 5, a connecting frame 6, a first transmission rod 7, a fan blade 8, a fixing frame 9, a breathable plate 10, a filter bag 11, and an auxiliary cleaning mechanism.

[0024] like Figure 3As shown, the connecting ring 2 is slidably connected to the mounting plate 1. A blocking rod 3 passes through the inside of the connecting ring 2. One end of the blocking rod 3 passes through the connecting ring 2 and enters the mounting plate 1. The pulse blowing head 4 is installed at the top of the blocking rod 3. The upper surface of the pulse blowing head 4 is connected to the output end of the external pulse blowing device. The blocking plate 5 is installed on the outer surface of the blocking rod 3. A connecting frame 6 is sleeved on the outer surface of the blocking rod 3. The first transmission rod 7 is rotatably connected inside the connecting frame 6. The outer surface of the first transmission rod 7 is equipped with fan blades 8. There are three sets of fan blades 8. The fan blades 8 drive the first transmission rod 7 to rotate under the blowing of the gas. The fixing frame 9 is installed on the lower surface of the connecting frame 6. The inner side of the fixing frame 9 is equipped with a breathable plate 10. Both the breathable plate 10 and the connecting frame 6 have breathable holes. The gas discharged from the pulse blowing head 4 can pass through the breathable holes. The bottom end of the first transmission rod 7 is rotatably connected to the inside of the breathable plate 10. A cloth bag 11 is installed on the lower surface of the connecting ring 2. An auxiliary cleaning mechanism is set on the lower surface of the breathable plate 10.

[0025] like Figure 4 As shown, the auxiliary cleaning mechanism includes a mounting frame 12, a reciprocating screw 13, a moving tube 14, and a limiting block 15. The mounting frame 12 is installed on the lower surface of the ventilated sheet 10. The reciprocating screw 13 is rotatably connected inside the mounting frame 12. The moving tube 14 is set on the outer surface of the reciprocating screw 13 via a screw nut. The limiting block 15 is slidably connected inside the mounting frame 12 via a connecting groove. The front of the limiting block 15 is installed on the outer surface of the moving tube 14. The top end of the reciprocating screw 13 is installed on the bottom end of the first transmission rod 7. A second transmission rod 16 is rotatably connected inside the limiting block 15. A cleaning plate 17 is installed on the outer surface of the second transmission rod 16. The cleaning plate 17 is made of rubber and is relatively soft. The length of the cleaning plate 17 is greater than the radius of the cloth bag 11. The cleaning plate 17 can bend during the rotation of the second transmission rod 16 without damaging the cloth bag 11. During the rotation, the cleaning plate 17 beats the inside of the cloth bag 11 to achieve the function of auxiliary cleaning. The outer surface of the second transmission rod 16 is equipped with a transmission gear 18, and the outer side of the mounting bracket 12 is equipped with a rack 19. The transmission gear 18 meshes with the rack 19. There are two sets of cleaning plates 17, second transmission rod 16, transmission gear 18 and rack 19. It should be noted that the impact force of the gas blown out by the pulse blowing head 4 to the middle and lower layers of the cloth bag 11 is weakened, but it does not disappear completely in the middle and lower layers of the cloth bag 11. Therefore, when the cleaning plate 17 moves to the middle and lower layers of the cloth bag 11, the gas blown in will also play a certain auxiliary role.

[0026] In this embodiment, as Figure 1As shown, a limiting frame 20 is installed on the upper surface of the mounting plate 1. A first limiting plate 21 is slidably connected inside the limiting frame 20. A limiting pin 22 is threaded through the outer side of the limiting frame 20. One end of the limiting pin 22, threaded into the limiting frame 20, abuts against the first limiting plate 21. The first limiting plate 21 is slidably connected to the mounting plate 1 through an auxiliary groove. A second limiting plate 23 is installed on the lower surface of the first limiting plate 21. A limiting ring 24 is installed inside the second limiting plate 23. The limiting ring 24 is fitted onto the outer surface of the filter bag 11 to control the filter bag 11 during the dust removal process. To prevent the filter bags from swinging around during the dust removal process, the mounting plate 1 has a splicing block 25 slidably connected inside via a splicing groove. A splicing pin 26 passes through the upper surface of the splicing block 25. One end of the splicing pin 26, which passes through the splicing block 25, is threaded into the mounting plate 1. It should be noted that the mounting plate 1 is part of the bag filter. During assembly, multiple sets of mounting plates 1 are connected by splicing blocks 25 and splicing pins 26. The exhaust gas to be treated passes through multiple sets of filter bags 11 to block the dust. The exhaust gas after dust removal is discharged for the next process.

[0027] In this embodiment, the pulse blowing head 4 is connected to an external pulse blowing device to connect multiple sets of mounting plates 1. The splicing block 25 is slid into the mounting plate 1 along the splicing groove. The splicing pin 26 is inserted into the mounting plate 1 through the splicing block 25. Then, the splicing pin 26 is rotated clockwise to fix the splicing block 25 in the mounting plate 1. The first limiting plate 21 is moved downward along the limiting frame 20. The first limiting plate 21 moves downward and passes through the second limiting plate 23, which drives the limiting ring 24 to move downward, so that the operator can adjust according to the length of the cloth bag 11. After adjustment, the limiting pin 22 is inserted into the limiting frame 20 and then rotated clockwise to press against the first limiting plate 21.

[0028] Manipulate the connecting ring 2 to slide into the mounting plate 1, the cloth bag 11 passes through the mounting plate 1 and extends into the limiting ring 24, the auxiliary cleaning mechanism extends into the cloth bag 11, so that the connecting frame 6 contacts the upper surface of the connecting ring 2, manipulate the pulse blowing head 4 to pass the blocking rod 3 through the connecting frame 6 and insert it into the connecting ring 2, and then move downward through the blocking rod 3 to pass through the connecting ring 2 and insert it into the mounting plate 1, so that the blocking plate 5 contacts the connecting frame 6;

[0029] When the filter bag 11 needs cleaning, air is drawn in through an external pulse blowing device and blown out along the pulse blowing head 4 to clean the dust in the upper layer of the filter bag 11. At the same time, the airflow drives the three sets of fan blades 8 to rotate. The fan blades 8 drive the first transmission rod 7 to rotate. The rotation of the first transmission rod 7 drives the reciprocating screw 13 to rotate. The rotation of the reciprocating screw 13 drives the moving tube 14 to move up and down reciprocally through the screw nut. The up and down movement of the moving tube 14 drives the limit block 15 to move up and down along the mounting bracket 12. The up and down movement of the limit block 15 drives the second transmission rod 16 to move up and down. The up and down movement of the second transmission rod 16 drives the... The transmission gear 18 moves up and down, causing it to mesh with the rack 19 and rotate. The rotation of the transmission gear 18 drives the second transmission rod 16 to rotate along the limit block 15. The rotation of the second transmission rod 16 drives the cleaning plate 17 to rotate. During the rotation of the cleaning plate 17, it can also move up and down with the second transmission rod 16. The rotation of the cleaning plate 17 beats the cloth bag. With the help of air circulation, the cleaning plate 17 cleans the dust in the lower layer of the cloth bag 11, so that blowing and beating can be carried out at the same time. This strengthens the linkage between the pulse blowing head 4 and the cleaning plate 17 and improves the cleaning effect of the device.

[0030] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
