Description

Technical Field

[0001] This utility model relates to the field of calcium carbonate powder processing technology, specifically an anti-clogging structure for a calcium carbonate powder conveying pipeline. Background Technology

[0002] Calcium carbonate powder, as a common raw material, is widely used in various fields such as building materials, plastics, rubber, and coatings in industrial production. However, during the transportation of calcium carbonate powder, especially when transporting it over long distances or along complex paths through pipelines, the problem of agglomeration due to the moisture content of the powder often arises. Particularly at bends and other turning points, the change in airflow direction and the slowdown in speed can easily cause calcium carbonate powder to stagnate and adhere to the pipe wall, leading to blockages and severely affecting the transportation efficiency and normal operation of the system.

[0003] Traditional solutions mainly include periodically shutting down the machine to clean the inside of the pipes and using vibrators to assist in conveying. However, these methods not only increase maintenance costs but also fail to fundamentally solve the problem. In particular, on continuous production lines, shutdowns for cleaning will cause huge economic losses. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide an anti-clogging structure for a calcium carbonate powder conveying pipeline. This structure automatically removes clumps and deposits at the inner and outer corners of the bends in the pipe section by mechanical means, ensuring smooth material transportation while reducing the frequency of manual intervention and maintenance, and improving the reliability and efficiency of the entire conveying system.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: an anti-clogging structure for a calcium carbonate powder conveying pipeline, including a conveying pipeline, wherein an opening is provided at the outer corner of the bend section of the conveying pipeline, and a dust collection pipe is provided on the bend section, with the opening located inside the port of the dust collection pipe;

[0006] The upper end of the ash collection pipe is provided with a slot at the position where it contacts the conveying pipe. A baffle plate is inserted through the slot, and the two ends of the baffle plate are respectively passed through two slots. A first traction seat is provided on the horizontal section of the conveying pipe. The first traction seat is connected to one end of the baffle plate by a traction rope. A second traction seat is provided on the vertical section of the conveying pipe. The second traction seat is connected to the other end of the baffle plate by a traction rope.

[0007] The baffle includes a dust-blocking area and a dust-passing area of ​​the same size. The dust-passing area is provided with dust-passing holes. The baffle is fitted to the outer corner surface of the bend section.

[0008] In a preferred embodiment, the first traction seat includes a drum portion with a torsion spring, and the traction rope at one end of the baffle is wound around the drum.

[0009] The second traction seat includes a drum section, and the traction rope at the other end of the baffle is wound around the drum. The drum on the second traction seat is driven by a motor to realize the winding and unwinding action.

[0010] In a preferred embodiment, the conveying pipe is further provided with a brush block, and the bottom of the brush block is provided with brush bristles.

[0011] In a preferred embodiment, a pull rope is also wound around the second traction seat. The pull rope passes through the vertical section wall of the conveying pipe and extends into the conveying pipe before being connected and fixed to the ash-brushing block.

[0012] In a preferred embodiment, the top of the brush block is provided with a top rod, and the end of the top rod is provided with a roller. The roller contacts and presses against the inner wall of the conveying pipe.

[0013] In a preferred embodiment, the push rod has a "Y" shaped structure, and two rollers are provided at the upper end of the push rod.

[0014] In a preferred embodiment, the second traction seat includes three rope winding sections located at both ends and the middle of the drum. The two rope winding sections at both ends of the drum are used for winding the traction rope, and the rope winding section in the middle of the drum is used for winding the pull rope.

[0015] The second traction seat has a driven gear at one end, the motor is fixedly mounted on the outer wall of the conveying pipe, and the motor drive shaft has a driven gear that meshes with the driven gear.

[0016] The anti-clogging structure for a calcium carbonate powder conveying pipeline provided by this utility model has the following beneficial effects:

[0017] (1) By setting openings and dust collection pipes at the outer corner of the bend section, and with the design of adjustable baffles, the calcium carbonate powder that has clumped due to water content can be removed in time, avoiding it from adhering to the pipe wall and causing blockage. It is suitable for bend positions where material stagnation is easy to form, and greatly improves the anti-blockage ability of the system.

[0018] (2) The position of the baffle and the action of the brush block are controlled by a motor-driven traction rope system, realizing the automatic cleaning process of the clumps. This not only reduces the need for manual intervention, but also reduces the workload and cost of daily maintenance, and improves the convenience and efficiency of operation;

[0019] (3) By ensuring that the inside of the pipeline is clean and unobstructed, a stable airflow speed can be maintained, and the conveying resistance caused by material retention or blockage can be reduced, thereby ensuring the efficient and continuous transport of calcium carbonate powder, which is especially important for production lines that need to run for a long time.

[0028] In a preferred embodiment, the first traction seat 7 includes a drum portion with a torsion spring, and the traction rope 9 at one end of the baffle 5 is wound around the drum.

[0029] The second traction seat 8 includes a drum portion, and the traction rope 9 at the other end of the baffle 5 is wound around the drum. The drum on the second traction seat 8 is driven by the motor 16 to realize the winding and unwinding action.

[0030] In a preferred embodiment, the conveying pipe 1 is further provided with a brush block 10, and the bottom of the brush block 10 is provided with brush bristles 11.

[0031] In a preferred embodiment, a pull rope 14 is also wound around the second traction seat 8. The pull rope 14 passes through the vertical section wall of the conveying pipe 1 and extends into the conveying pipe 1 before being connected and fixed to the ash-brushing block 10.

[0032] In a preferred embodiment, the brush block 10 is provided with a top rod 12 at its top and a roller 13 at its end. The roller 13 contacts and presses against the inner wall of the conveying pipe 1.

[0033] In a preferred embodiment, the top rod 12 has a "Y" shaped structure, and two rollers 13 are provided at the upper end of the top rod 12.

[0036] The anti-clogging structure for a calcium carbonate powder conveying pipeline disclosed in this invention operates on the following principle during calcium carbonate powder conveying operations:

[0037] During normal conveying, the baffle 5 is in a closed state, that is, the ash blocking area 501 covers the opening 2 to prevent calcium carbonate powder from entering the ash collection pipe 3.

[0038] When cleaning is required, start motor 16 and pull baffle 5 with traction rope 9 to move it so that ash passage 502 is aligned with opening 2, allowing powder adhering to the outer corner of the bend to fall into the ash collection pipe and be collected.
