Description

Technical Field

[0001] The utility model relates to the technical field of bag filters, in particular to DMC series pulse jet bag filters. Background Art

[0002] With the continuous improvement of environmental protection requirements in the industrial production process, bag filters are widely used in various dust control occasions due to their high particulate matter capture ability. However, traditional bag filters have some problems in actual use, especially in the replacement and maintenance of filter bags. Existing bag filters usually adopt complex internal structure designs, making the installation and disassembly processes of filter bags cumbersome and time-consuming. This not only increases the maintenance cost but also may lead to an extended equipment downtime, affecting production efficiency.

[0003] Specifically, the filter bags of traditional bag filters are usually fixed to the frame, requiring professionals for disassembly and assembly, and some external structures may need to be removed during the replacement process, which not only increases the operation difficulty but also may cause secondary pollution or damage to other components. In addition, due to the relatively compact position of the filter bags and limited operating space, the difficulty of maintenance work is further increased. These problems result in a long maintenance cycle, high labor intensity, and potential safety hazards.

[0004] To solve the above problems, we propose the DMC series pulse jet bag filters. This bag filter realizes more convenient replacement and maintenance of filter bags by optimizing the installation method of filter bags. Summary of the Utility Model

[0005] To overcome the disadvantage that the filter bags of traditional bag filters are usually fixed to the frame and are difficult to operate during replacement and maintenance, the utility model provides the DMC series pulse jet bag filters. This bag filter realizes more convenient replacement and maintenance of filter bags by optimizing the installation method of filter bags.

[0006] The technical solution is as follows: The DMC series pulse jet bag filter includes a treatment box. Support frames are fixedly connected to the four corners of the treatment box. A clean gas outlet is communicated with the treatment box. A dirty gas inlet is communicated with the side of the treatment box away from the clean gas outlet. A baffle is slidably connected to the bottom end of the treatment box. Horizontally symmetric opening and closing plates are rotatably connected to the treatment box. Horizontally symmetric guide rails are fixedly connected inside the treatment box. A sliding plate is slidably connected between the horizontally symmetric guide rails. A fixing frame is slidably connected to the sliding plate. A first spring is connected between the fixing frame and the sliding plate at equally spaced intervals. The fixing frame is close to the opening and closing plate. An extrusion rod is fixedly connected to the opening and closing plate. The extrusion rod is in extrusion cooperation with the adjacent contact block. Placement holes are provided at equally spaced intervals on the sliding plate. A cloth bag is placed in each placement hole of the sliding plate. The top end of the cloth bag is pressed by the fixing frame. Pulse jet pipes are fixedly connected inside the treatment box at equally spaced intervals. One end of the pulse jet pipe extends out of the treatment box. A dust shaking component for shaking off the dust on the cloth bag is provided on the sliding plate and the treatment box. A separation component for separating the dirty gas during ash discharge is provided in the lower part of the treatment box.

[0007] Preferably, the dust shaking component includes horizontally symmetric contact rods fixedly connected to the sliding plate. A horizontally symmetric group of vertical rods is fixedly connected to the top end inside the treatment box. A cross plate is fixedly connected between the bottom ends of each group of vertical rods. A vertically symmetric sliding rod is slidably connected to the cross plate. A second spring is connected between the sliding rod and the adjacent cross plate. An extrusion frame is fixedly connected between the vertically symmetric sliding rods. The extrusion frame is in extrusion cooperation with the adjacent contact rod.

[0008] Preferably, the separation component includes an installation frame fixedly connected inside the treatment box. Equally spaced partition plates are rotatably connected to the installation frame. Horizontally symmetric sliding rods are slidably connected to the bottom end of the treatment box. A top plate is fixedly connected between the top ends of the horizontally symmetric sliding rods. The top plate is in extrusion cooperation with the partition plate. Horizontally symmetric push frames are fixedly connected to the baffle.

[0009] Preferably, a transparent observation window is provided on the treatment box.

[0010] Preferably, a handle is fixedly connected to the opening and closing plate.

[0011] Preferably, the side of the push frame close to the sliding rod is inclined, and the push frame is in extrusion cooperation with the adjacent sliding rod.

[0012] Advantages of the present utility model: The dust-containing gas is introduced into the treatment box through the turbid gas inlet, and the dust-containing gas is filtered by the cloth bag. The dust is intercepted on the outer side of the cloth bag, and the purified gas passes through the cloth bag upward and is discharged through the clean gas outlet. When the dust on the cloth bag continuously increases and affects the filtration, high-pressure gas is ejected one by one through the pulse injection pipe and quickly reaches the top of the filter bag to shake off the dust. When it is necessary to replace and maintain the cloth bag, the opening and closing plate is controlled to rotate backward to open, and then the sliding plate is controlled to drive the cloth bag to move backward and extend. After the fixing frame slides upward and lifts, the cloth bag can be removed from the placement hole of the sliding plate for replacement. After the replacement is completed, the fixing frame presses down on the top of the cloth bag to fix it, realizing more convenient replacement and maintenance of the cloth bag.

Detailed implementation mode

[0023] The present utility model will be further described below in conjunction with the attached drawings and embodiments.

[0024] Embodiment 1: The DMC series pulse jet bag filter, as Figures 1-9 shown, includes a treatment box 1, a support frame 2, a clean air outlet 3, a turbid air inlet 4, a baffle 5, an opening and closing plate 6, a guide rail 7, a sliding plate 8, a fixing frame 81, a first spring 82, a contact block 83, an extrusion rod 84, a cloth bag 9, a pulse jet pipe 10, a dust shaking assembly and a separation assembly. A transparent observation window is provided on the front side of the treatment box 1. Support frames 2 are fixedly connected to the four corners of the lower part of the treatment box 1. The clean air outlet 3 communicates with the upper front side of the treatment box 1. The turbid air inlet 4 communicates with the lower rear side of the treatment box 1. A baffle 5 is slidably connected to the lower side of the treatment box 1. The opening and closing plates 6 which are symmetric left and right are rotatably connected to the rear side of the treatment box 1. A handle is fixedly connected to the middle of the opening and closing plate 6. Guide rails 7 are fixedly connected to the left and right sides of the upper part inside the treatment box 1. A sliding plate 8 is slidably connected between the left and right guide rails 7. A fixing frame 81 is slidably connected to the sliding plate 8. First springs 82 distributed at equal intervals are connected between the fixing frame 81 and the sliding plate 8. Contact blocks 83 which are symmetric left and right are fixedly connected to the rear part of the fixing frame 81. An extrusion rod 84 is fixedly connected to the upper front side of the opening and closing plate 6. The extrusion rod 84 is in extrusion fit with the adjacent contact block 83. Placement holes distributed at equal intervals are formed in the sliding plate 8. A cloth bag 9 is placed in each placement hole of the sliding plate 8. The upper end of the cloth bag 9 is pressed by the fixing frame 81. Pulse jet pipes 10 distributed at equal intervals are fixedly connected to the upper part inside the treatment box 1. The front end of the pulse jet pipe 10 extends out of the treatment box 1. A dust shaking assembly for shaking off the dust on the cloth bag 9 is provided on the sliding plate 8 and the treatment box 1. A separation assembly for separating the turbid air during ash discharge is provided in the lower part inside the treatment box 1.

[0025] When using this device, the staff introduce the dust-containing gas into the treatment box 1 through the turbid gas inlet 4. Large-particle dust will directly fall to the lower part of the treatment box 1, while the fine dust can move upward with the air. The dust-containing gas is filtered by the cloth bag 9. The dust is intercepted on the outer side of the cloth bag 9, and the purified gas passes upward through the cloth bag 9 and is discharged through the clean gas outlet 3. When the dust on the cloth bag 9 continuously increases and affects the filtration, high-pressure gas is ejected one by one through the pulse injection pipe 10 and quickly reaches the top of the filter bag. The high-pressure gas forms a powerful air current, and the shock wave generated by this air current will cause the cloth bag 9 to expand and contract instantaneously, thereby shaking off the dust attached to the surface of the filter bag. The shaken-off dust falls into the lower part of the treatment box 1. The staff can open the baffle 5 to discharge the dust in the lower part of the treatment box 1. When it is necessary to replace and maintain the cloth bag 9, the staff control the opening and closing plate 6 to rotate backward to open. The backward rotation of the opening and closing plate 6 drives the extrusion rod 84 to rotate backward and no longer presses the contact block 83. Then, the staff control the sliding plate 8 to slide backward and pull out, thereby driving the cloth bag 9 to move backward. At this time, the staff control the fixing frame 81 to slide upward, and the first spring 82 deforms. After the fixing frame 81 is lifted upward, the cloth bag 9 can be removed from the placement hole of the sliding plate 8 for replacement. After the replacement is completed, the fixing frame 81 is released. Under the action of the reset of the first spring 82, the fixing frame 81 slides downward accordingly to press the top of the cloth bag 9, thereby fixing the cloth bag 9 on the sliding plate 8. After the maintenance of the cloth bag 9 is completed, the staff control the sliding plate 8 to slide backward to reset, and then control the opening and closing plate 6 to slide backward to close. The backward sliding of the opening and closing plate 6 drives the extrusion rod 84 to rotate backward to press the contact block 83, thereby ensuring the fixing effect of the fixing frame 81 on the cloth bag 9.

[0026] Embodiment 2: On the basis of Embodiment 1, as Figure 7 and Figure 8 shown, the dust shaking assembly includes a contact rod 11, a vertical rod 12, a horizontal plate 13, a sliding rod 14, a second spring 15 and an extrusion frame 16. The front part of the sliding plate 8 is fixedly connected with symmetrically arranged contact rods 11 on the left and right. A group of symmetrically arranged vertical rods 12 are fixedly connected to the upper side inside the treatment box 1. There are two vertical rods 12 in a group. A horizontal plate 13 is fixedly connected between the lower sides of the two vertical rods 12 in each group. The front and rear parts of the horizontal plate 13 are both slidably connected with sliding rods 14. A second spring 15 is connected between the sliding rod 14 and the adjacent horizontal plate 13. An extrusion frame 16 is fixedly connected between the front and rear sliding rods 14. The extrusion frame 16 is in extrusion fit with the adjacent contact rod 11.

[0027] When using this device, the backward sliding of the sliding plate 8 drives the contact rod 11 to move backward. When the contact rod 11 moves backward, it is in extrusion fit with the extrusion frame 16. Under the action of the expansion and contraction of the second spring 15 and the sliding guidance of the sliding rod 14, the extrusion frame 16 will continuously move up and down. By the extrusion fit between the contact rod 11 and the extrusion frame 16, the vibration of the sliding plate 8 can be controlled, thereby shaking off the dust on the cloth bag 9 for replacement.

[0028] As Figure 1 , Figure 2 and Figure 9 shown, the separating component includes an installation frame 17, a partition plate 18, a sliding rod 19, a top plate 20 and a pushing frame 21. An installation frame 17 is fixedly connected to the lower part inside the treatment box 1. The installation frame 17 is rotatably connected with equidistantly distributed partition plates 18. The lower part of the treatment box 1 is slidably connected with symmetrically arranged sliding rods 19 on the left and right. A top plate 20 is fixedly connected between the upper sides of the two sliding rods 19 on the left and right. The top plate 20 is in extrusion fit with the partition plate 18. Symmetrically arranged pushing frames 21 are fixedly connected to the lower side of the baffle 5. The side of the pushing frame 21 close to the sliding rod 19 is inclined. The pushing frame 21 is in extrusion fit with the adjacent sliding rod 19.

[0029] When the device is in use, when the baffle 5 slides backward to open for ash discharge, the pushing frame 21 will also move backward. The pushing frame 21 moves backward to squeeze the sliding rod 19 to slide upward. The sliding rod 19 slides upward to drive the top plate 20 to move upward. The top plate 20 moves upward to drive the partition plate 18 to rotate upward. After the partition plate 18 rotates upward and closes, it cooperates with the installation frame 17 to isolate the upper part of the treatment box 1, preventing the dust-containing gas from blowing downward and affecting ash discharge. When the ash discharge is completed, the baffle 5 slides backward to drive the pushing frame 21 to move backward. When the pushing frame 21 moves backward until it no longer squeezes the sliding rod 19, under the action of gravity, the sliding rod 19 and the top plate 20 move downward accordingly, and the partition plate 18 will also rotate downward to open.

[0030] Although the present invention has been described in detail with reference to the above embodiments, it is obvious to those skilled in the art through the present disclosure that various changes or modifications can be made to the present invention without departing from the principle and spirit scope defined by the claims. Therefore, the detailed description of the embodiments of the present disclosure is only used to explain, rather than to limit the present invention, and the scope of protection is defined by the content of the claims.
