Description

Technical Field

[0001] The utility model relates to the technical field of powder conveying pipelines, in particular to an efficient powder conveying pipeline. Background Art

[0002] Powder conveying pipelines are widely used in the conveying of light dry powders such as pulverized coal, petroleum coke powder, chemical powder, metal powder, ceramic powder, alumina, and protein powder. Common powder conveying methods include tube chain conveying, lift conveying, and pneumatic conveying, among which pneumatic conveying is more widely used.

[0003] In the Chinese utility model patent with the publication number CN219057866U, a high-compression powder conveying pipeline is disclosed. By setting a powder conveying pump, the feed pipe at the input end of the powder conveying pump extracts the powder in the storage bin and transports it to the guide pipe through the output end of the powder conveying pump, and then transports it to the powder conveying pipe through the guide pipe. The air flow generated by the Roots blower is transported to the powder conveying pipe through the output end of the Roots blower. The air flow generated by the Roots blower drives the powder in the powder conveying pipe to move to the right and pass through the connecting pipe to be transported to the collection bin. The connection between the pipes can be made more tight by the connecting blocks and connecting grooves provided on the connecting flange, improving the tightness at the pipe connection, preventing environmental pollution caused by leakage at the pipe connection, and at the same time improving the transportation efficiency.

[0004] Regarding the above related technologies, the inventor believes that there are the following defects: when the device transports powder, there may be some agglomerated powders in the powder. The agglomerated powders are prone to form accumulations, thus affecting the transportation of the powder in the pipeline. These powders need to be dispersed. At the end of the transportation, some powders still adhere to the inner wall of the pipeline or accumulate at the bottom of the inner wall of the pipeline, and these powders need to be cleaned to avoid the pollution of the subsequent transported powder by these residual powders.

[0008] The vibration component includes a mounting box and a support plate fixedly connected to the top and bottom of the pipeline respectively. On one side of the inner wall of the mounting box, a moving plate is slidably connected at equal intervals. The bottom end of the moving plate is fixedly connected to an abutting block.

On the front and back surfaces of the pressed block, sliding blocks are fixedly connected. One side of the sliding block is slidably connected to a sliding plate, and the top of the sliding plate is fixedly connected to one side of the inner wall of the mounting box. The support plate is fixedly connected to the front and back surfaces of the inner wall of the mounting box. A linear groove is formed on the surface of the support plate. A moving block is slidably connected in the linear groove. A long rod is fixedly connected to the left side of the moving block. The long rod penetrates through the inside of the moving plate. A connecting rod is rotatably connected to the surface of the moving block. One end of the connecting rod is rotatably connected to a turntable. A fan is sleeved outside the middle shaft of the turntable. An air inlet cylinder is installed outside the fan. The air inlet cylinder is installed on the top of the mounting box. One end of the air inlet cylinder is communicated with one end of a connecting pipe. A communicating pipe is communicated with the right side of the air inlet cylinder. One end of the communicating pipe is communicated with the right side of the air inlet plate.

[0009] As a further improvement of the above solution, a limiting straight groove for the limiting block to slide is formed on the top of the inner wall of the pipeline, ensuring that the limiting block can move along the limiting straight groove without deviation.

[0010] As a further improvement of the above solution, both the abutting block and the pressed block are triangular blocks, and a contact wheel is installed on the surface of the abutting block, facilitating the abutting block to press the pressed block.

[0011] As a further improvement of the above solution, sealing bearings are installed on both the top and bottom of the pipeline, and the middle shaft of the turntable is installed inside the sealing bearings, ensuring the normal operation of the turntable.

[0012] As a further improvement of the above solution, a linear sliding groove for the moving plate to move is formed on one side of the inner wall of the mounting box, ensuring that the moving plate can move normally.

[0013] As a further improvement of the above solution, a through hole for the striking rod to pass through is formed at the bottom of the mounting box, ensuring the normal operation of the striking rod.

[0014] As a further improvement of the above solution, threaded holes are provided on the surfaces of both the scraping plate disc and the pipeline. Bolts are threadedly connected in the threaded holes, facilitating the fixation and movement of the scraping plate disc.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] 1. By setting the vibration assembly in the present utility model, when transporting powder, air is first introduced into the air filling pipe. During the process of air introduction, the air will first enter the air intake cylinder, driving the fan to rotate, so that the turntable drives the moving block to reciprocate through the connecting rod. As a result, the abutting block continuously squeezes the pressed block back and forth. With the acting force of the spring, the striking rod continuously knocks on the surface of the pipeline, thereby realizing that during pipeline transportation, the powder in the pipeline is vibrated by the knocking, the caked powder is shaken loose, reducing the situation of caked powder blockage and improving the transportation efficiency of the pipeline.

[0017] 2. By setting the cleaning assembly in the present utility model, after the pipeline completes the transportation of powder, rotate the air intake plate so that the air intake plate disengages from the scraping plate. Then rotate the bolt to release the restriction between the scraping plate and the pipeline. Then rotate the winding roller, so that the winding roller drives the scraping plate to move through the pulling rope, scraping off the powder attached to the inner wall of the pipeline and accumulated at the bottom of the inner wall of the pipeline, facilitating the cleaning of the powder in the pipeline.
