[0002] The dust conveying and dust removing device mainly relates to a positive pressure dense phase pneumatic dust conveying system, which is a high-efficiency and reliable material conveying system.
[0003] However, the non-pneumatic dust conveying and dust removing device does not have a fluidization facility during the unloading process, and relies on the suction force of the suction and discharge tank truck to perform negative pressure pneumatic dust conveying on the dust generated in the pipeline. UTILITY MODEL CONTENTS
[0004] The main purpose of the utility model is to provide a dust fast flowing negative pressure fluidization device, which can effectively solve the problems in the background art.
[0005] To achieve the above-mentioned purpose, the utility model adopts the technical scheme of:
[0006] A dust fast flowing negative pressure fluidization device, comprising a dust conveying pipeline, a first mounting seat and a second mounting seat are fixedly installed on the outer surface of the dust conveying pipeline, a sealing device is fixedly installed on the upper end of the first mounting seat and the second mounting seat, a connecting pipeline is fixedly installed on the upper end of the first mounting seat, a fixing bolt is installed at the front end of the connecting pipeline, and internal threads are engraved on the inner wall of the connecting pipeline.
[0007] By loosening the fixing bolt on the connecting pipeline, then rotating the rotating handle to rotate the plug out of the connecting pipeline, the pipeline of the suction and discharge tank truck can be connected to the connecting pipeline, so that the suction force of the suction and discharge tank truck can be used to quickly suck external air through the connecting pipeline, forming a spiral air flow in the dust conveying pipeline and quickly removing the accumulated dust in the dust conveying direction.
[0008] Preferably, the sealing device includes a mounting head, a rotating handle fixedly mounted on the upper end of the mounting head, and a plug fixedly mounted on the lower end of the mounting head. The plug is engraved with external threads on the upper surface of the plug, and a bolt hole is formed at the front end of the plug. The mounting head is fixedly mounted to the upper end of the connecting pipe via the plug. After the plug is tightened by the thread, it is locked by the fixing bolt. This double fixing method further improves the stability of the plug after installation. After the plug is installed, it just fills the connecting pipe, preventing dust from easily entering the connecting pipe during operation.
[0009] Preferably, the connecting pipe is inclined at an angle of forty-five degrees.
[0010] Preferably, the external thread and the internal thread are adapted to each other, and the bolt hole and the fixing bolt position correspond to each other front to back.
[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] 1. By setting two connecting pipes at the turning point of the ash conveying pipeline, and the two connecting pipes are installed at a forty-five-degree angle according to the ash conveying direction, during the ash conveying process, once dust accumulation occurs in the bend, loosen the fixing bolts on the connecting pipe, then unscrew the plug column out of the connecting pipe through the rotating handle on the sealing device, and finally connect the pipe of the suction and discharge tanker to the connecting pipe. In this way, the suction force of the suction and discharge tanker can be used to quickly inhale the external air through the connecting pipe, forming a spiral airflow in the ash conveying pipeline, and quickly removing the accumulated dust along the ash conveying direction. Not only does it greatly reduce the probability of dust accumulation in the pipeline and blockage, and there is no ash leakage pollution at the suction and discharge port, but only two pipes need to be added at the pipe bend, which is economical and solves the problem of high cost of adding fluidizing equipment to each non-pneumatic ash conveying system.
[0013] 2. After the plug column is tightened through the thread, it is locked by the fixing bolt. The double fixing method further improves the stability of the plug column after installation. Moreover, after the plug column is installed, the connecting pipe is just filled to prevent dust from entering the connecting pipe when the ash conveying pipe is in operation.
