Detailed Implementation

[0031] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0032] Example 1

[0033] A specific embodiment of this utility model discloses an industrial dust removal device, such as... Figure 1 As shown, the system includes a housing 1, a filter cartridge 2, a dust collection component 3, a connecting pipe 4, and a pre-filtration unit 5. The housing 1 is connected to the dust collection component 3, and the pre-filtration unit 5 is connected to the housing 1 via the connecting pipe 4. These components are used to filter large dust particles in the air. The filter cartridge 2 is located inside the housing 1 and is used to filter the air entering the housing 1. An air outlet is also provided on the housing 1 to discharge the filtered clean air.

[0034] Preferably, the housings of the outer shell 1, the dust collection component 3, and the pre-filter unit 5 are made of PBT (polybutylene terephthalate) material, thereby increasing the strength, fatigue resistance, and aging resistance of the industrial dust removal device and extending its service life.

[0035] For example, the dust collection component 3 is a dust collection box or dust collection container.

[0036] like Figure 1 As shown, the pre-filtration unit 5 includes a cone 51, an air inlet 52, and a particle collection box 53. One end of the cone 51 is connected to the outer shell 1 through a connecting pipe 4, and the other end of the cone 51 is connected to the particle collection box 53. The end of the cone 51 connected to the particle collection box 53 is set in a cone shape, and the air inlet 52 is located in the middle of the cone 51.

[0037] When the industrial dust removal device is in operation, air enters the cone 51 through the air inlet 52, forming a spiral airflow inside the cone 51. This causes large dust particles in the air to move towards the inner wall of the cone 51 under the action of centrifugal force and fall into the particle collection box 53 along the inner wall of the cone 51, thereby removing large dust particles from the air. The air that has had its large dust particles filtered out by the pre-filtration unit 5 enters the outer casing 1 through the connecting pipe 4, and is further filtered by the filter cartridge 2 before being discharged from the air outlet, completing the air dust removal and filtration process.

[0038] Furthermore, such as Figure 2 As shown, the pre-filtration unit 5 also includes a drive assembly 54 and a cleaning assembly 55. The drive assembly 54 and the cleaning assembly 55 are disposed inside the cone 51. The drive assembly 54 is connected to the cleaning assembly 55 and is used to clean the inner wall of the cone 51 to prevent large dust particles from adhering to the wall and affecting the working performance of the cone 51.

[0039] The drive assembly 54 includes a motor 541, a planetary reducer 542, and a lead screw 543. The motor 541 is fixed inside the cone 51. The output shaft of the motor 541 is connected to the lead screw 543 through the planetary reducer 542 to drive the lead screw 543 to rotate and prevent the lead screw 543 from rotating too fast.

[0040] like Figures 2-3As shown, the cleaning assembly 55 includes an inner connecting ring 551, an outer connecting ring 552, and a cleaning part 553. The inner connecting ring 551 is connected to a lead screw 543, and the rotation of the lead screw 543 can drive the inner connecting ring 551 to move up and down. The outer connecting ring 552 is connected to the inner connecting ring 551 by a bearing, and the outer connecting ring 552 can move up and down with the inner connecting ring 551. A fan blade component is provided on the outer connecting ring 552, and the spiral motion of air in the cone 51 can drive the outer connecting ring 552 to rotate. The cleaning part 553 is connected to the outer connecting ring 552 and cooperates with the inner wall of the cone 51. The outer connecting ring 552 can drive the cleaning part 553 to rotate along the inner wall of the cone 51 and move up and down with the inner connecting ring 551, thereby cleaning the inner wall of the cone 51 and causing large dust particles adhering to the inner wall of the cone 51 to enter the particle collection box 53.

[0041] like Figure 3 As shown, the cleaning unit 553 includes a support rod 5531, a spring 5532 and a cleaning rod 5533. The support rod 5531 is connected to the outer connecting ring 552, and the cleaning rod 5533 is hinged to the support rod 5531. One end of the spring 5532 is connected to the support rod 5531, and the other end is connected to the cleaning rod 5533.

[0042] When the cleaning rod 5533 moves to the conical end face of the cone 51, the cleaning rod 5533 is rotated by the inner wall of the cone 51 towards the outer connecting ring 552, which compresses the spring 5532 and keeps the cleaning rod 5533 in close contact with the inner wall of the cone 51 to clean the cone 51; when the cleaning rod 5533 leaves the conical end face of the cone 51, the spring 5532 returns to its original position and causes the cleaning rod 5533 to rotate away from the outer connecting ring 552, so that the cleaning part 553 always remains in close contact with the inner wall of the cone 51.

[0043] Preferably, the cleaning rod 5533 is equipped with a scraper or brush head to better clean large dust particles adhering to the inner wall of the cone 51.

[0044] Preferably, a controller is provided on the motor 541. The controller can control the rotation direction of the motor 541 according to the length of the cone 51, so that the cleaning part 553 moves up and down periodically to clean the cone 51. The controller is prior art and will not be described in detail here.

[0045] It is understandable that the pre-filter unit 5 can also be installed inside the housing 1, thereby saving the space occupied by the industrial dust removal device and increasing its applicability to different spaces.

[0046] Example 2

[0047] A specific embodiment of this utility model discloses an industrial dust removal device. The difference from embodiment 1 is that a gravity sensor is installed in the particle collection box 53 and / or dust collection component 3. When the dust or particulate matter collected in the particle collection box 53 and / or dust collection component 3 reaches a certain weight, the gravity sensor will sound an alarm to remind the user to clean the particle collection box 53 and / or dust collection component 3.

[0048] Compared with existing technologies, the industrial dust removal device of this invention, by setting a pre-filtration unit 5, can filter large particulate dust in the air, thereby preventing large particulate dust from entering the filter cartridge 2 and causing filter cartridge blockage, affecting the filtration effect and service life of the industrial dust removal device, and preventing large particulate dust from entering the outer shell 1, causing wear and tear on the mechanical and circuit structures inside the outer shell 1, leading to malfunctions. The outer shell 1, dust collection component 3, and the shell of the pre-filtration unit 5 of this invention are made of PBT (polybutylene terephthalate) material, thereby increasing the strength, fatigue resistance, and aging resistance of the industrial dust removal device, and extending the service life of the industrial dust removal device. This invention, by setting a drive component 54 and a cleaning component 55, enables the cleaning component 55 to clean the large particulate dust adhering to the inner wall of the cone 51 under the drive of the drive component 54, improving the filtration effect of the pre-filtration unit 5. By setting a gravity sensor in the particle collection box 53 and / or dust collection component 3, the user can be promptly reminded to replace the particle collection box 53 and / or dust collection component 3.

[0049] 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 changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
