Description

Technical Field

[0001] The utility model relates to the technical field of pneumatic ash conveying, in particular to a pipeline anti-blocking structure of a pneumatic ash conveying system. Background Art

[0002] The main function of the pipeline anti-blocking structure of the pneumatic ash conveying system is to prevent the ash conveying pipeline from being blocked, ensuring the normal operation and efficient operation of the pneumatic conveying system. In the pneumatic conveying system, dust and particles are transported in the pipeline by the airflow, but due to various reasons, such as dust accumulation, once blockage occurs, it will not only affect production efficiency, but also may cause equipment damage and safety accidents.

[0003] For example, the Chinese patent with publication number CN217200835U proposes a pneumatic conveying system anti-blocking pipeline, which includes a pipeline body, and the pipeline body is fixedly connected to multiple ash discharge pipelines at intervals along the length direction, and each ash discharge pipeline is fixedly connected to an ash discharge valve. The utility model has a reasonable and compact structure, and the arrangement of the ash discharge pipeline and the ash discharge valve significantly reduces the work intensity and work time of the pipe blockage dredging operation, and has the characteristics of high efficiency and safety.

[0004] In the above scheme, only when blockage occurs, the on-duty personnel only need to determine which section of the pipeline is blocked and then perform pressure relief operations. However, there are still the following disadvantages: pressure relief is performed only after blockage occurs in the pipeline, and dredging is still required, which affects work efficiency. Utility Model Content

[0005] The utility model aims to provide a pipeline anti-blocking structure of a pneumatic ash conveying system to solve the problem that only after blockage occurs in the pipeline can pressure relief be performed on it, and dredging treatment is still required, which affects work efficiency.

[0006] In order to achieve the above-mentioned purpose of the utility model, the utility model adopts the following technical scheme: a pipeline anti-blocking structure of a pneumatic ash conveying system, including an ash storage hopper, the ash storage hopper is arranged above the base, a conveying bin is fixedly installed at the discharge port of the base, an ash conveying pipe is fixedly installed on one side of the conveying bin, an ash delivery pipe is fixedly installed on one end of the ash conveying pipe, a driving motor is fixedly installed on the top surface of the base, one end of the driving motor rotating shaft extends to the interior of the conveying bin, a rotating disk is fixedly installed on one end of the driving motor rotating shaft, two scraping rods are fixedly installed on one side of the rotating disk, and the outer wall of the scraping rod is in contact with the inner wall of the ash conveying pipe and the ash delivery pipe.

[0007] Preferably, a stepper motor is fixedly mounted on the top surface of the base, a rotating rod is fixedly mounted on one end of the rotating shaft of the stepper motor, and a plurality of rubber rods are fixedly mounted on the outer wall of the rotating rod.

[0008] Preferably, a support block is fixedly mounted on the top surface of the base, and the rotating rod is rotatably inserted into the interior of the support block.

[0009] Preferably, an air supply pipe is fixedly installed inside the ash conveying pipe, a hot air blower is fixedly installed on the top surface of the base, the other end of the air supply pipe is fixedly installed with the air outlet of the hot air blower, and a partition pipe is fixedly installed inside the ash conveying pipe.

[0010] Preferably, a closed valve is fixedly installed inside the ash conveying pipe.

[0011] Preferably, the outer wall of the partition tube is provided with a dehumidification port, a dehumidification pipe is fixedly installed inside the dehumidification port, an industrial dehumidifier is fixedly installed on the top surface of the base, and one end of the dehumidification pipe is fixedly installed at the air intake port of the industrial dehumidifier.

[0012] Compared with the prior art, the pipeline anti-blocking structure of a pneumatic ash conveying system adopting the above technical solution has the following beneficial effects:

[0013] 1. During use, when the pneumatic ash conveying system is started, it can effectively prevent dust accumulation in the conveying pipeline, and constantly clear the dust that may adhere to and stay on the inner wall of the pipeline, which can more effectively prevent the deposition and agglomeration of materials in the pipeline, and help reduce the frequency of blockage. Therefore, it can reduce production interruptions and downtime caused by clearing blockages, and improve the working efficiency of the pneumatic ash conveying system;

[0014] Second, through the stepper motor, when the stepper motor is started, it drives the rotating rod to rotate, so that the rubber rod knocks the outer wall of the ash conveying pipe and the ash delivery pipe, so that the fine dust inside will not adhere to the inner wall, reducing the possibility of blockage. Through the support block, the rotation of the rotating rod is more stable, playing a supporting role;

[0015] 3. The interior of the ash conveying pipe can be divided through the separation pipe to create a closed space. When the hot air blower is started, hot air can be transported into the interior to heat the interior of the ash conveying pipe, thereby dehumidifying the material entering the ash conveying pipe. When the air pressure between the ash conveying pipe and the separation pipe is too high, the sealing valve opens to discharge the air. When the industrial dehumidifier is started, the moisture inside the ash conveying pipe can be separated and sucked out to keep the interior dry, thereby avoiding excessive moisture in the material and causing caking and blockage.
