Description

Technical Field

[0001] The utility model relates to the technical field of pulse dust collectors, in particular to a multi-tube pulse dust collector. Background Art

[0002] Pulse bag dust collector is a mechanical shaking type dust collector that can collect and separate dust and particles in the air flow. It mainly uses mechanical vibration to clean the dust. Pulse dust collector is a new type of high-efficiency pulse dust collector improved on the basis of bag dust collector. It combines the advantages of various pulse jet dust collectors with chamber backblowing, overcomes the shortcomings of insufficient chamber cleaning intensity and uneven distribution of inlet and outlet air, and expands the scope of application. When the dust-laden gas enters the dust collector from the air inlet, it first hits the inclined plate and baffle in the middle of the inlet and outlet, and the airflow turns to flow into the ash hopper. At the same time, the airflow speed slows down. Due to inertia, the coarse dust particles in the gas flow directly into the ash hopper, which plays a role of pre-dust collection. The airflow entering the ash hopper then turns upward and passes through the filter bag with a metal skeleton inside. The dust is captured on the outer surface of the filter bag, and the purified gas enters the cleaning chamber above the filter bag chamber and is discharged at the air outlet.

[0003] The pulse dust collector in the prior art adopts a bag type, which has a single dust removal method and poor effect. It is difficult to clean the dust, causing internal dust to fly.

[0004] The patent announcement number CN218046957U was retrieved, and the patent name is a public material of a multi-cyclone pulse dust collector with convenient dust discharge, and specifically discloses a multi-cyclone pulse dust collector with convenient dust discharge, including a pulse box, a dust inlet pipe is installed on one side of the pulse box, a pulse box is installed on the upper end face of the pulse box, an exhaust pipe is fixed on one side of the pulse box, a plurality of dust filter bags are installed on the lower end face of the pulse box, a dust discharge hopper is fixed on the lower end face of the pulse box, guide rails are fixed on both sides of the inner cavity of the pulse box, a sliding sleeve is slidably sleeved on the surface of the guide rail, an annular frame is fixed between the two sliding sleeves, a spring is fixed on the inner cavity of the annular frame, a brush body is fixed on the extended end of the spring, a pneumatic push rod is fixed on the lower end face of the inner cavity of the pulse box, the pneumatic push rod is transmission connected to the annular frame, and a lower bin body is fixed on the lower end face of the dust discharge hopper.

[0005] Through the analysis of the above public materials, it can be known that the device can push the annular frame to move up and down through the pneumatic push rod, so that the brush body installed inside the annular frame can scrape the surface of the dust filter bag to clean it, which can prevent excessive dust from accumulating on the surface of the dust filter bag. When the pulse cannot clean the dust, blockage occurs. At the same time, the liquid pump can spray dust-reducing water in the pulse box to prevent the dust raised in the pulse box from accumulating on the dust filter bag. At the same time, it can also improve the dust removal effect of the gas, making the gas purification more thorough, and the spraying water can be recycled to reduce the water cost of the device. The problem to be solved is that the dust bag cannot be cleaned in time, causing blockage of the dust bag. This method can prevent the dust bag from clogging, but in terms of the dust removal effect, the method is single and the effect is poor. Utility Model Content
