A blowing pipe used in a dust collector
Release time:2022-08-22 Click:494When the bag filter is working, the filter bag will leave fine dust, and it needs to be sprayed with a blowing pipe at certain intervals. The blowing pipe is generally a long circular nozzle. There are several nozzles (ie short blowing pipes). When working, the high-pressure high-speed air flow controlled by the pulse valve enters the long nozzles, and then blows in the opposite direction to the center of the bag through each nozzle to remove the adhesion on the outer surface of the filter bag. to prevent excessive dust from accumulating. Ideally, the short blowing pipe is vertically facing the bag, so that when the compressed air is sprayed, it can form a uniform force on the inner wall of the bag, and the bag will not be blown. However, in the actual working process, the first injection pipe is a round pipe. The injection short pipe welded on the injection pipe is difficult to control the welding quality due to the intersecting line of the two circles, and the injection short pipe may be inclined after welding. Secondly, when replacing the cloth bag, the injection pipe must be disassembled and installed every time. If the installation hole of the connecting flange at the side end of the injection pipe is dislocated, the short injection pipe will be inclined as a whole, but due to the limitation of the installation environment, it is not easy to detect; When the blowpipe is being cut, the round pipe is not easy to locate, which affects the cutting efficiency. These will cause the short blowing pipe not to go down vertically, so that the corresponding cloth bag is easily broken under the injection of compressed air in the short blowing pipe, which affects the normal operation of the production.
In view of the defects existing in the above-mentioned prior art, the technical problem to be solved by the present utility model is to provide a blowing pipe that can always keep the short blowing pipe vertically downward.
This utility model will apply for a patent on November 8, 2021, and the patentee is Ningbo Changqing Environmental Protection Technology Co., Ltd. The product discloses a blowing pipe used in a dust collector, including a long blowing pipe for guiding compressed air, wherein the cross-section of the long blowing pipe is a square outer surface, and one end of the long blowing pipe is fixed with a square The hole flange is fixed with a plug at the other end, and several short spray pipes are fixed on the center line of one side surface of the long spray pipe. By changing the traditional round pipe-shaped injection pipe into a square injection pipe, the cloth bag will not be broken during operation; it is also easy to disassemble and inspect during maintenance; when cutting the injection pipe, It is also easy to operate.
Compared with the prior art, the utility model has the following advantages by changing the traditional round-pipe-shaped injection pipe into a square injection pipe:
1: When welding the short blowing pipe on the long blowing pipe, the original two pipes that are both round pipes are welded to each other, and the accuracy of the intersecting line where the two circles intersect is difficult to ensure. After changing to a square, the welding It is easy to ensure the consistency of product quality, and the short blowing pipe can always be kept vertically downward (with the cloth bag kept vertically downward), and the cloth bag will not be broken by blowing.
2: During maintenance, repair and disassembly, if the square blowing long pipe is dislocated during installation, it will be misaligned by 90 degrees, and it can be checked visually; while the round pipe-shaped long blowing pipe is installed. If dislocation occurs, it is only less than 30 degrees of dislocation, because the space is relatively narrow, it is not easy to check out.
