Unit fluidization, high-efficiency gas-saving, blockage control, anti-wear, leading automatic embolism full-pipe conveying system

Abstract

The invention discloses a unit fluidifying efficient throttling block-treating wear-resistant leading type automatic plug pipe conveying system which comprises an air supply branch pipe, a blowing pipe, an air escape pipe, a first air cylinder, a second air cylinder, an air guide piston and a balancing piston. The first end of the first air cylinder is fixedly connected to the second end of the second air cylinder, the air guide piston is located in the second air cylinder, the balancing piston is located in the first air cylinder, the air guide piston and the balancing piston are fixedly connected through a piston rod, one end of the air escape pipe in fluid communication to an air escape inlet in the second air cylinder between the air guide piston and the balancing piston, and the otherend of the air escape pipe is in fluid communication to an ash conveying pipe; one end of the blowing pipe is in fluid communication to the ash conveying pipe in front of the air escape pipe along the ash conveying direction while the other end of the blowing pipe is in fluid communication to a blowing hole in the cylinder of the second air cylinder. The unit fluidifying efficient throttling block-treating wear-resistant leading type automatic plug pipe conveying system has the advantages of not plugging the pipe, conveying fluids in a long distance and being low in energy consumption, smallin wear, high in efficiency, large in specific gravity, simple in configuration, loose in mounting condition and the like.

Description

technical field [0001] The invention relates to the technical field of powder or small particle pneumatic conveying. Specifically, it is a unit fluidized high-efficiency air-saving, anti-blocking, anti-wear, leading-type automatic embolism full-pipe conveying system. Background technique [0002] At present, no matter what kind of pneumatic ash conveying, including air supply type, double casing, plunger type, plug column type, dilute phase, traditional so-called dense phase, etc., will cause frequent pipe blockage, serious wear, and large air consumption. Disadvantages, among which pipe blockage and wear are common failures of pneumatic ash conveying systems, are more or less impossible to avoid. Pipe plugging is a frequent and difficult to eradicate failure in the pneumatic ash conveying system. It will happen regardless of the distance of the conveying distance, regardless of the size of the unit, or whether the coal quality is good or bad. It has happened several times...

Problems solved by technology

In the prior art, there are also valves that can control the intermittent supply of air to the ash conveying pipeline (see Chinese patent documents CN207986195U and CN101225897B for details). The overflow of the dust-carrying ash conveying pipe needs to enter the interior of the ash supply valve to trigger the air supply action, but this This kind of air supply valve to the ash conveying pipe and the overflow air path of the ash conveying pipe that triggers the air supply share a section of the air path, so that there is a lot of dust on the air supply path, which seriously pollutes the air supply path and the air supply components. Thereby greatly reducing the reliability of the gas supply action of the gas supply components and the service life of the gas supply components
