[0028] The present invention will now be described in further detail with reference to the accompanying drawings.

In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0030] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] like Figure 1 As shown, a pipeline dust cleaning and separation device comprises a mounting frame 1. The mounting frame 1 adopts a hollow circular tube to facilitate the subsequent assembly of various mechanisms.

[0032] The mounting frame 1 is also provided with a plurality of moving mechanisms 3. The moving mechanisms 3 are evenly spaced and distributed in the circumferential direction at both ends of the mounting frame 1. In this embodiment, the number of the moving mechanisms 3 is 6, and the specific number can also be reasonably selected according to actual needs.

[0033] like Figure 2 As shown, the moving mechanism 3 includes a support arm 31 hinged to the mounting frame 1, a third motor 32 is provided on the support arm 31, and one end of the support arm 31 away from the mounting frame 1 is rotatably connected to a second rotating rod 33, a roller 34 is connected to the second rotating rod 33, and the third motor 32 drives the roller 34 to rotate through a third transmission belt 35. The moving mechanism 3 supports the mounting frame 1, and drives the second rotating rod 33 to rotate through the third motor 32 and the third transmission belt 35. During the cleaning process, the roller 34 is attached to the inner wall of the pipe, so that the mounting frame 1 can translate inside the pipe.

[0034] like Figures 3 to 5 As shown, a dust removal mechanism 2 and an anti-adhesion mechanism are provided on the outer side of the mounting frame 1 .

[0035] The dust removal mechanism 2 includes an inner tube 21 disposed in the mounting frame, a fan 22 disposed outside the mounting frame 1, and a telescopic cleaning mechanism 23. The telescopic cleaning mechanism 23 rotates to remove dust from the inner wall of the pipeline. The inner tube 21 has a left chamber 211 and a right chamber 212 that are isolated from each other. The left chamber 211 and the right chamber 212 are separated by a partition 213 in the inner tube 21.

[0036] The air inlet pipe 221 of the fan 22 extends into the left chamber 211, and the air exhaust pipe 222 of the fan 22 extends into the right chamber 212. The fan 22 sucks the gray gas and dust into the left chamber 211 and then discharges the gas into the right chamber 212.

[0037] The gas on the left side of the mounting frame 1 is sucked into the left chamber 211 through the fan 22 and then sent to the right side of the mounting frame 1 from the right chamber 212. A filter screen 27 is also provided in the inner tube 21. The filter screen 27 is located in the left chamber 211 and on the left side of the air inlet pipe 221. The dust entering the left chamber 211 will be intercepted by the filter screen 27 to achieve dust adsorption, thereby completing gas-powder separation.

[0038] The left end of the inner tube 21 extends out of the mounting frame 1, and the rotating block 24 is rotatably connected to the left end of the inner tube 21 through a bearing, so that the rotating block 24 can rotate on the inner tube 21. The mounting frame 1 is also provided with a first motor 25, and the first motor 25 drives the rotating block 24 to rotate through a first transmission belt 26, and the telescopic cleaning mechanism 23 and the left disk 41 are fixedly connected to the rotating block 24. The telescopic cleaning mechanism 23 and the rotating block 24 rotate synchronously and revolve around the inner tube 21, so that the circumference of the inner wall of the pipeline can be cleaned in all directions.

[0039] In this embodiment, the number of telescopic cleaning mechanisms is 2, and the specific number of telescopic cleaning mechanisms can be reasonably selected according to actual needs.

[0040] The telescopic cleaning mechanism 23 includes a spring tube 231 fixedly connected to the rotating block 24, and the spring tube 231 rotates with the rotating block 24 to realize the synchronous rotation of the telescopic cleaning mechanism. A spring 232 is sleeved inside the spring tube 231, and the upper end of the spring 232 is connected to a telescopic rod 233, and the lower end of the spring 232 is connected to the rotating block 24. The top of the telescopic rod 233 is also rotatably connected to a top wheel 234. The spring tube 231 provides an upward thrust for the telescopic rod 233, ensuring that the cleaning brush 237 at the upper end can fit on the inner wall of the pipeline for cleaning. At the same time, the top wheel 234 also contacts the inner wall of the pipeline, ensuring that the telescopic cleaning mechanism can rotate smoothly on the inner wall of the pipeline.

[0041] like Figure 6As shown, the telescopic rod 233 is connected to a second motor 235, and the upper end of the telescopic rod 233 is connected to a first rotating rod 236. The second motor 235 drives the first rotating rod 236 to rotate through a second transmission belt 238, and a cleaning brush 237 is provided on the first rotating rod 236. The cleaning brush 237 is driven to rotate by the second motor 235, the second transmission belt 238 and the first rotating rod 236. The cleaning brush 237 cleans the inner wall of the pipeline during its rotation. The telescopic cleaning mechanism adopts a cleaning method combining revolution and rotation to further improve the cleaning effect and comprehensively clean the dust inside the pipeline.

[0042] The anti-adhesion mechanism 4 includes a left disc 41 located outside the left chamber 211 and a right disc 42 located outside the right chamber 212. The left disc 41 is close to the entrance of the left chamber 211 and there is a gap between the left disc 41 and the right disc 42 is spaced apart from the exit of the right chamber 212. The right disc 42 is fixedly connected to the mounting frame 1 through a fixing rod 45. The left disc 41 is connected to the rotating block 24 and rotates with the rotating block 24. Both the left disc 41 and the right disc 42 adopt a disc structure that matches the pipeline, and the diameter of the left disc 41 is larger than that of the right disc 42. The left disc 41 is located inside the cleaning brush 237, and a gap is formed between the left disc 41 and the inside of the pipeline for air flow.

[0043] A high-pressure area is formed between the right disk 42 and the left disk 41, and the dust in the blown pipe is collected by the left disk 41. When the fan 22 sucks the gas from the left chamber 211 through the air inlet pipe, the gas separated by the filter 27 will be discharged outward through the right side of the mounting frame 1. Since the areas of the right disk 42 and the left disk 41 are both large, the gas cannot move quickly to the rear side of the movement direction. After the gas is blown to the surface of the right disk 42, it will form a leftward recoil due to the resistance of the right disk 42, thereby forming a high-pressure area between the right disk 42 and the left disk 41, so that the swept dust will not move to the rear side of the movement direction, so that it can be better collected by the left disk 41 to avoid residue inside the pipe.

[0044] The left disc 41 is provided with an extension rod 43 extending into the inner tube 21, and the extension rod 43 is connected with a scraper 44 in contact with the filter 27. The rotation of the left disc 41 drives the extension rod 43 and the scraper 44 to rotate, and the scraper 44 drops the dust adhered to the surface of the filter 27 to avoid clogging of the filter 27, thereby ensuring the suction strength.

[0045] The left outer wall of the mounting frame 1 is also connected to a static eliminator 46. During operation, the static eliminator 46 can be started to ionize the air, and since the right disk 42 forms a recoil airflow to the left, the airflow drives the ionized air to be discharged to the left through the edge of the left disk 41, thereby eliminating the static electricity at the dust and the cleaning brush 237, reducing the adsorption amount of dust after being collected, and reducing the adsorption effect of dust and the cleaning brush 237 due to static electricity, so that the dust on the inner wall of the pipeline can be better removed.

[0046] The working principle of the present invention is: the pipeline dust cleaning and separation device is sent into the pipeline, and the third motor 32 on the moving mechanism 3 drives the roller 34 to rotate, so that the pipeline dust cleaning and separation device moves along the pipeline for cleaning. During the movement of the pipeline dust cleaning and separation device, the first motor 25 drives the telescopic cleaning mechanism 23 to rotate around the inner wall of the pipeline, and the second motor 235 drives the cleaning brush 237 to rotate at the same time to clean the inner wall of the pipeline. During the cleaning process, the fan 22 works synchronously, and the gas containing dust will be sucked into the inner tube 21 by the fan 22, and the dust and gas will be separated by the filter 27 of the inner tube 21, and the gas will be discharged from the right side of the inner tube 21. At the same time, due to the influence of the left disk 41 and the right disk 42, the gas around the mounting frame 1 flows to the left disk 41 under the action of the high-pressure area, and the swept dust is collected by the left disk 41 along the airflow, avoiding dust residue and improving the cleanliness of cleaning.

[0047] In summary, the pipeline dust cleaning and separation device of the present invention forms a high-pressure area inside the pipeline, and uses the airflow generated by the high-pressure area to collect dust in the air, thereby having a good cleaning effect.

[0048] The above description is based on the ideal embodiment of the present invention. Through the above description, relevant personnel can make various changes and modifications without departing from the technical concept of the present invention. The technical scope of the present invention is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
