Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, and particularly to a filtering structure of a high-hardness industrial waste gas treatment device. Background Art

[0002] A high-hardness industrial waste gas treatment device is a device that can effectively remove harmful substances in waste gas, especially for treating specific components in high-hardness waste gas. The device adopts advanced physical, chemical or biological treatment technologies to ensure that the waste gas meets the environmental protection discharge standards, while protecting the environment and human health.

[0003] Existing industrial waste gas treatment devices use a filtering structure to filter waste gas. During the use process, dust and particulate matter will gradually accumulate in the filtering structure, resulting in a decline in its filtering efficiency. Therefore, it is necessary to regularly treat the filtering structure. However, when treating the filtering structure, it is necessary to remove the filtering structure from the device, and the operation is relatively cumbersome, with insufficient practicability.

[0004] In view of the above problems, the utility model proposes a filtering structure of a high-hardness industrial waste gas treatment device. Content of the Utility Model

[0005] The purpose of the utility model is to provide a filtering structure of a high-hardness industrial waste gas treatment device. An activity channel is opened on the inner wall of the outer mounting block. A limiting plate is fixedly connected to the opening of the activity channel. One end of the limiting plate is rotatably connected to a threaded rod. An activity block is threadedly connected to the outer wall of the threaded rod. The activity block is slidably connected to the inner wall of the activity channel, thereby solving the problems in the background art.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A filtering structure of a high-hardness industrial waste gas treatment device, including an outer mounting block and a filtering main body arranged in the inner cavity of the outer mounting block. An exhaust main body is arranged at the upper end of the filtering main body. An activity channel is opened on the inner wall of the outer mounting block. A limiting plate is fixedly connected to the opening of the activity channel. One end of the limiting plate is rotatably connected to a threaded rod. An activity block is threadedly connected to the outer wall of the threaded rod. The activity block is slidably connected to the inner wall of the activity channel.

[0007] Further, the end of the activity block away from the activity channel is fixedly connected to the filtering main body.

[0008] Further, the lower end of the exhaust main body is connected to a mounting plate. A filtering groove is opened inside the filtering main body.

[0009] Further, through holes with the same structure as the filtering groove are opened on the outer wall of the mounting plate.

[0010] Further, the lower end of the through hole is axially connected with a first clamping plate and a second clamping plate, and the inner walls of the first clamping plate and the second clamping plate are axially connected with an upper inclined rod A and an upper inclined rod B respectively. A first pressing block is axially connected between the two groups of upper inclined rods A, and a second pressing block is axially connected between the two groups of inclined rods B.

[0011] Further, the first pressing block and the second pressing block are symmetrically distributed about the centers of the first clamping plate and the second clamping plate.

[0012] Further, a return spring is fixedly connected between the first pressing block and the second pressing block.

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

[0014] A filtering structure of a high-hardness industrial waste gas treatment device proposed by the present utility model drives a threaded rod to rotate through an external motor of the threaded rod, so that a moving block moves on the inner wall of a moving channel, and drives a filtering main body to move out from the inner wall of an outer mounting block through the moving block.

It solves the problem that during the use of the filtering structure, dust and particulate matter will gradually accumulate, resulting in a decrease in its filtering efficiency. Therefore, it is necessary to regularly process the filtering structure. However, when processing the filtering structure, it is necessary to disassemble the filtering structure from the device, and the operation is relatively cumbersome and the practicability is insufficient.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-4 , in order to solve the problem that during the use of the filtering structure, dust and particulate matter will gradually accumulate, resulting in a decrease in its filtering efficiency, so it is necessary to regularly process the filtering structure. However, when processing the filtering structure, it is necessary to remove the filtering structure from the device, and the operation is relatively cumbersome and the practicability is insufficient. The following preferred technical solutions are provided:

[0022] A filtering structure of a high-hardness industrial waste gas treatment device, including an outer mounting block 1 and a filtering main body 2 arranged in the inner cavity of the outer mounting block 1. An exhaust main body 3 is arranged at the upper end of the filtering main body 2. A moving channel 4 is opened on the inner wall of the outer mounting block 1. A limiting plate 5 is fixedly connected to the opening of the moving channel 4. One end of the limiting plate 5 is rotatably connected to a threaded rod 6. A moving block 7 is threadedly connected to the outer wall of the threaded rod 6, and the moving block 7 is slidably connected to the inner wall of the moving channel 4.

[0023] One end of the moving block 7 away from the moving channel 4 is fixedly connected to the filtering main body 2. The lower end of the exhaust main body 3 is connected to a mounting plate 8. A filtering groove 9 is opened inside the filtering main body 2. Through holes having the same structure as the filtering groove 9 are opened on the outer wall of the mounting plate 8.

[0024] A first clamping plate 10 and a second clamping plate 11 are axially connected to the lower end of the through hole. Upper inclined rods A12 and upper inclined rods B13 are axially connected to the inner walls of the first clamping plate 10 and the second clamping plate 11 respectively. A first pressing block 14 is axially connected between the two groups of upper inclined rods A12, and a second pressing block 15 is axially connected between the two groups of inclined rods B13. The first pressing block 14 and the second pressing block 15 are symmetrically distributed about the centers of the first clamping plate 10 and the second clamping plate 11. A return spring 16 is fixedly connected between the first pressing block 14 and the second pressing block 15.

[0025] Specifically, after the filtering body 2 has been filtering waste gas for a long time, dust and particulate matter will accumulate in the cavity. At this time, an electric motor is externally connected to the threaded rod 6, and the threaded rod 6 is driven to rotate by the electric motor, so that the movable block 7 moves on the inner wall of the movable channel 4. The filtering body 2 is driven by the movable block 7 to move out of the inner wall of the outer mounting block 1, which is convenient for the staff to handle and has strong practicability. It solves the problem that the filtering structure will gradually accumulate dust and particulate matter during use, resulting in a decline in its filtering efficiency. Therefore, the filtering structure needs to be processed regularly. However, when processing the filtering structure, it is necessary to disassemble the filtering structure from the device, and the operation is relatively cumbersome and the practicability is insufficient.

[0026] When the filtering body 2 moves out of the inner wall of the outer mounting block 1, the filtering groove 9 will be separated from the first clamping plate 10 and the second clamping plate 11 at the lower end of the through hole of the mounting plate 8. When separating, it will first be squeezed by the inner wall of the filtering groove 9, driving the first clamping plate 10 and the second clamping plate 11 to rotate at an angle, thereby driving the upper inclined rod A12 and the upper inclined rod B13 to rotate at an angle. The first pressing block 14 and the second pressing block 15 are driven by the upper inclined rod A12 and the upper inclined rod B13 to squeeze the return spring 16. Thus, after complete separation, due to the reaction force of the return spring 16, the first clamping plate 10 and the second clamping plate 11 will be driven to return to their original positions. When the filtering body 2 moves back to the inner wall of the outer mounting block 1 again, similarly, the first clamping plate 10 and the second clamping plate 11 will rotate at an angle. After the filtering groove 9 and the through hole are completely aligned, the first clamping plate 10 and the second clamping plate 11 will be clamped on the inner wall of the filtering groove 9, and the operation is convenient.

[0027] To sum up: After the filtering body 2 has been filtering waste gas for a long time, dust and particulate matter will accumulate in the cavity. At this time, an electric motor is externally connected to the threaded rod 6, and the threaded rod 6 is driven to rotate by the electric motor, so that the movable block 7 moves on the inner wall of the movable channel 4. The filtering body 2 is driven by the movable block 7 to move out of the inner wall of the outer mounting block 1. When the filtering body 2 moves out of the inner wall of the outer mounting block 1, the filtering groove 9 will be separated from the first clamping plate 10 and the second clamping plate 11 at the lower end of the through hole of the mounting plate 8. When separating, it will first be squeezed by the inner wall of the filtering groove 9, driving the first clamping plate 10 and the second clamping plate 11 to rotate at an angle, thereby driving the upper inclined rod A12 and the upper inclined rod B13 to rotate at an angle. The first pressing block 14 and the second pressing block 15 are driven by the upper inclined rod A12 and the upper inclined rod B13 to squeeze the return spring 16. Thus, after complete separation, due to the reaction force of the return spring 16, the first clamping plate 10 and the second clamping plate 11 will be driven to return to their original positions. When the filtering body 2 moves back to the inner wall of the outer mounting block 1 again, similarly, the first clamping plate 10 and the second clamping plate 11 will rotate at an angle. After the filtering groove 9 and the through hole are completely aligned, the first clamping plate 10 and the second clamping plate 11 will be clamped on the inner wall of the filtering groove 9.
