Description

Technical Field

[0001] This utility model relates to the technical field of unclogging tools for silica conveying pipelines, and in particular to a self-unclogging device for silica conveying pipelines. Background Technology

[0002] Silica is a white powder, a general term for amorphous silica and silicate products, mainly referring to precipitated silica, fumed silica, and ultrafine silica gel, and also including powdered synthetic aluminum silicate and calcium silicate, etc. In the production process of silica powder, the powder material needs to be transferred multiple times via conveying pipelines. The static electricity generated during the conveying process causes the powder to mainly adhere to the bottom of the inner wall of the conveying pipeline, which easily leads to blockage over long-term operation. In particular, the powder is also affected by gravity, causing self-settlement, resulting in even more powder accumulating at the bottom of the pipeline. Regular cleaning is necessary to prevent blockage. Existing cleaning equipment usually cleans curved pipes; however, it is difficult to avoid using curved pipes in actual transportation. Therefore, this invention improves upon existing equipment to address the above problems. Utility Model Content

[0024] Working principle: When using this utility model, first power is supplied to all electrical equipment. Then, the device is carried to the target pipe opening using the handle. The front end of the device is aligned with the pipe opening and inserted. The rotating rod 7, in conjunction with the support rod 9 and the first spring 11, drives the hard brush 8 to autonomously adapt and abut against the inner wall of the pipe. Then, the roller 18 enters the pipe and, under the action of the second spring 16, fixes the front sleeve 2 and the transmission components inside the front sleeve 2. Then, the device is continuously pushed into the pipe until the pushing belt 30 is completely inside the pipe. At this time, the pushing belt 30 is kept in place by the action of the third spring 20. The first motor 14 and the second motor 22 are started. The first motor 14 drives the front rotating drum 1 to rotate through the gear 13 and the gear sleeve 12, and drives the hard brush 8 to rotate around the front drum shaft 6, thereby cleaning the pipe wall. At the same time, the second motor 22 drives the push belt 30 to rotate through the belt 24 and the worm gear 26, thereby pushing the whole equipment forward. When the equipment enters the curved pipe, because the joint sleeve 3 and the joint shaft 4 are movable sleeve structures, plus the continuous thrust of the rear push component, the equipment can complete a maximum 90-degree turn, thereby realizing the ability to clear blockages in curved pipes.
