Description

TECHNICAL FIELD

[0001] The utility model relates to cloth bag dust removal technical field especially relates to a kind of spray pipe fixing device. BACKGROUND

[0002] The filter bag of bag-type dust collector is cleaned by compressed air, and the cleaning mechanism is composed of air pocket, spray pipe and electromagnetic pulse control valve, etc. One spray pipe is assembled at the top of the outlet of each row of filter bags in the filter chamber, and a spray port is arranged on the lower side of the spray pipe opposite to the center of the filter bag. Each spray pipe is provided with a pulse valve and is communicated with the compressed air pocket. When cleaning, the electromagnetic valve opens the pulse valve, and the compressed gas passes through each pulse valve in sequence in a very short time, and the air induced by the nozzle on the spray pipe enters the filter bag, forming an air wave, which causes the filter bag to expand and vibrate sharply from the top to the bottom, and the dust on the filter bag is shaken off. Therefore, the fixed installation of the spray pipe is very important for the dust collector.

[0003] For example, the utility model patent with patent number CN212166803U discloses a spray pipe fixing device, which includes a dust removal box, a plurality of dust removal filter bags vertically arranged in the dust removal box, and a plurality of spray pipes installed above the dust removal filter bags in a front-to-back direction and arranged in a left-to-right direction. The length of each spray pipe in the left-to-right direction is the same. The dust removal box has a fixed plate installed at the right end of each spray pipe. The fixed plate has a "Fang" shaped structure with a front-to-back opening to the left. Each fixed plate has an upper clamping groove with a downward opening at the lower part of the corresponding spray pipe.

[0004] In the above-mentioned prior art, the upper and lower fixed plates are connected by bolts. The spray pipes are fitted with the clamping grooves on the upper and lower fixed plates, thereby realizing the fixation of the spray pipes. However, this fixation method requires entering the interior of the dust collector during disassembly and assembly, which poses certain risks. Moreover, the bolts need to be screwed during disassembly and assembly, and the bolts are prone to falling into the dust collector, which reduces the work efficiency and results in poor practicability.
