Description

Technical Field

[0001] This utility model relates to the field of urban air pollution control technology, and in particular to an environmentally friendly dust removal device for air pollution control. Background Technology

[0002] After urban air pollution occurs, the air in cities will contain a large amount of harmful dust. In order to clean up the pollutants in the urban atmosphere, it is necessary to use dust removal equipment to collect and remove dust from the air in severely polluted areas.

[0003] Announcement No. CN219231875U proposes an environmentally friendly dust removal device for urban air pollution control. The device uses a centralized gas delivery box installed in the middle of the lower end of the filter screen frame. When gas is conducted into the dust removal box through the centralized gas delivery box, the gas is concentrated in the middle and conducted upwards, preventing the gas from blowing away dust and causing the collected dust inside the box to shake. At the same time, a conical cover plate is installed on the upper part of the centralized gas delivery box. The conical cover plate can carry the dust to both sides and prevent the dust accumulated after filtration from flowing back.

[0004] However, during the implementation of this device, when the filter screen is disassembled and cleaned, a lot of dust adheres to the surface of the filter screen. The shaking caused by disassembly will cause the dust to fall onto the workers and be inhaled, causing harm to the workers. Therefore, an environmentally friendly dust removal device for air pollution control has been proposed to solve the above problems. Utility Model Content

[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution: an environmentally friendly dust removal device for air pollution control, including a shell 1, an air inlet pipe 5 fixedly connected to the surface of the shell 1, a fixed frame 2 slidably connected inside the shell 1, a filter screen 9 fixedly connected inside the fixed frame 2, a baffle 12 fixedly connected inside the shell 1, the baffle 12 being L-shaped, and a shielding plate 13 fixedly connected to the surface of the fixed frame 2, the shielding plate 13 being composed of multiple telescopic sliding plates, and a third spring 18 being provided inside the shielding plate 13. By telescopically extending the shielding plate 13 to cover the filter screen 9, dust is prevented from falling randomly, thus protecting the staff.

[0024] The device draws in outside air through an air intake device and filters dust from the air through filter 9, as described in the comparative case, so it will not be explained further.

[0025] A fixed shell 3 is fixedly connected to the surface of the fixed frame 2. A threaded rod 14 is rotatably connected inside the fixed shell 3. A push rod 16 is threadedly connected to the surface of the threaded rod 14. The push rod 16 is slidably connected to the inside of the fixed shell 3. A limit rod 15 is fixedly connected inside the fixed shell 3. The surface of the limit rod 15 is slidably connected to the inside of the push rod 16. A locking rod 11 is slidably connected inside the outer shell 1. The surface of the locking rod 11 is inclined. By setting the locking rod 11, when the fixed block 10 corresponds to the locking rod 11, the fixed frame 2 is fixed, preventing the fixed frame 2 from sliding out at will. A second spring 17 is fixedly connected to the surface of the locking rod 11. The end of the second spring 17 away from the locking rod 11 is fixedly connected to the outer shell 1. A fixed block 10 is fixedly connected to the surface of the fixed frame 2. A motor 4 is fixedly connected to the surface of the fixed shell 3. The output end of the motor 4 is rotatably connected to the inside of the fixed shell 3, and the output end of the motor 4 is fixedly connected to the threaded rod 14.

[0026] A second limiting rod 8 is fixedly connected to the surface of the fixed frame 2, and the second limiting rod 8 is slidably connected to the inside of the outer shell 1. A first limiting rod 7 is fixedly connected to the surface of the fixed frame 2, and the first limiting rod 7 is slidably connected to the inside of the outer shell 1. A first spring 6 is fixedly connected to the surface of the fixed frame 2, and the end of the first spring 6 away from the fixed frame 2 is in contact with the inside of the outer shell 1. When the fixed frame 2 is located inside the outer shell 1, the first spring 6 is in a compressed state. By setting the first spring 6, when the fixed frame 2 slides out, it can be ejected a certain distance under the elastic force of the first spring 6, making it convenient for the staff to pull it out.

[0027] Working principle: When installing the filter screen 9, the operator pushes the filter screen 9, causing it to slide into the interior of the outer casing 1. This causes the baffle plate 13 on the fixing frame 2 to be blocked by the baffle plate 12. The baffle plate 13 contracts under pressure, and this contraction compresses the third spring 18, thus removing the baffle plate 13 from obstructing the filter screen 9's filtration. When the filter screen 9 needs to be removed for cleaning, the fixing frame 2 is pulled, causing it to slide out of the outer casing 1. Under the elastic force of the third spring 18, the baffle plate 13 returns to its original position, blocking the filter screen 9.

[0028] When the fixed frame 2 is inserted into the outer casing 1, the fixed frame 2 drives the fixed block 10 to move. As a result, the fixed block 10 moves and presses against the inclined surface of the clamping rod 11. The clamping rod 11 moves upward under the force, causing the second spring 17 to deform. When the clamping rod 11 corresponds to the fixed block 10, under the elastic force of the second spring 17, the clamping rod 11 inserts into the interior of the fixed block 10, blocking the sliding out of the fixed frame 2. At the same time, by starting the motor 4, the motor 4 drives the threaded rod 14 to rotate. As a result, due to the blocking of the limiting rod 15 on the pushing rod 16, the pushing rod 16 moves upward with the rotation of the threaded rod 14. As a result, the pushing rod 16 pushes the clamping rod 11, so that the clamping rod 11 moves out of the interior of the fixed block 10 and no longer fixes the fixed frame 2. This allows the fixed frame 2 to be pulled, avoiding the need for the staff to disassemble the filter screen 9 one by one, making it easier for the staff to use.

[0029] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
