A self-priming fly ash sampling device

Abstract

The invention discloses a self-priming fly ash sampling device, the structure of which includes an air inlet connecting pipe, an air inlet valve, and a pressure gauge. The fly ash sampling device is provided with a check structure and a uniform flow mechanism inside the sampling pipe, and the fly ash Enter the inside of the anti-backflow tube, turn the turning knob to make the first bevel gear rotate, drive the uniform screw to rotate, and connect the rotating shaft to drive the transmission cam to rotate, at this time the transmission pin pushes the reciprocating push rod to move, and the reciprocating push rod drives the ejection plate The fly ash adsorbed on the inner wall of the sampling tube is pushed out, and the fly ash is evenly transmitted; by pressing the traction rod, the traction rod moves on the fixed guide rod, which drives the moving hook to deviate and separates from the fixed hook. The anti-backflow pipe is removed and cleaned to prevent fly ash from flowing back, and evenly push out the fly ash to prevent the fly ash from clogging inside the sampling tube, which affects the quality of fly ash treatment, and enables the staff to loosen and clean the non-return structure, saving labor .

Description

technical field [0001] The invention relates to the technical field of waste incineration fly ash detection, in particular to a self-priming fly ash sampling device. Background technique [0002] Waste incineration fly ash requires a fly ash sampling device to sample the fly ash. However, in the process of sampling the fly ash in the existing fly ash sampling device, the fly ash enters the collection tube from the sampling tube and is prone to backflow, which is difficult. Cleaning, and the fly ash cannot be transmitted evenly inside the sampling tube. Once the fly ash content is large, it will cause blockage inside the sampling tube, causing the fly ash sampling device to fail to work normally. Contents of the invention [0003] (1) Technical problems to be solved [0004] In order to overcome the deficiencies of the existing technology, a self-priming fly ash sampling device is now proposed, which solves the problem that the existing fly ash sampling device is prone to ...

Problems solved by technology

[0004] In order to overcome the deficiencies of the existing technology, a self-priming fly ash sampling device is now proposed, which solves the problem that the existing fly ash sampling device is prone to occur when the fly ash enters the collection cylinder from the sampling pipe during the process of sampling the fly ash. Backflow, difficult to clean, and the fly ash cannot be transmitted evenly inside the sampling tube. Once the fly ash content is large, it will cause blockage inside the sampling tube, resulting in the problem that the fly ash sampling device cannot work normally.
