Pure-bolt-connection pulse bag type dust collector

Abstract

The invention belongs to the technical field of protection devices, and specifically relates to a pure-bolt-connection pulse bag type dust collector, which comprises a frame shell, a filtering bag assembly, a blowing and ash removal device and an ash discharge device, wherein the filtering bag assembly and the ash discharge device are arranged in the frame shell, the blowing and ash removal deviceis arranged below the outer side, the filtering bag assembly arranged in a lower box body is used for supporting filtering bags, the filtering bags are tensioned and kept in a certain shape in the filtering and ash removal state so as to prevent the filtering bags from being folded and damaged, the blowing and ash removal device is used for removing accumulated ash on the surface of a cloth bag,and the ash discharge device is used for achieving mechanical ash discharge. According to the invention, all parts of the equipment are made of galvanized materials, and the whole structure does not adopt welding, so that all defects caused by welding are eliminated, the paint spraying procedure is thoroughly removed, and the environmental pollution caused by paint spraying is avoided; and the filtered gas is concentrated towards the center of the airflow partition plate, so the phenomenon that no gas penetrates through the filtering bag on the edge is avoided so as to improve the utilizationrate of the filtering bag to the maximum degree and effectively improve the dust removal efficiency of the equipment.

Description

technical field [0001] The invention belongs to the technical field of protective devices, and in particular relates to a purely bolt-connected pulse bag dust collector. Background technique [0002] The bag filter, also known as filter dust collector, is a dry high-efficiency dust collector, which uses a bag filter component made of fiber braid to capture solid particles in dusty gas. The principle of action is that the dust particles are intercepted when they collide with the fibers due to the inertial force when they go around the filter cloth fibers. Because of its large air volume, small footprint, high dust removal efficiency, simple structure and many other advantages, the pulse bag filter is widely used in metallurgy, machinery, cement, construction, food, pharmaceuticals, light industry, electric power and other industries. It has played a great role in removing dust pollution, protecting environmental sanitation, and improving working conditions. [0003] The fol...

Problems solved by technology

[0004] (1) The ash outlet of the ash hopper is a round mouth structure with a small diameter. The way of ash outlet is to flow out naturally from the ash outlet. Under the premise of ensuring that the side plate of the ash hopper does not store ash, a sufficient flow angle must be ensured, which is bound to Will cause the hopper height to be too high

[0005] (2) Most of the equipment is welded. During the welding process, due to the local heating of the connected components and uneven cooling after welding, welding residual stress and welding deformation will occur, which will affect the design size, stability, fatigue strength and aesthetics of the components. Sexuality and corrosion resistance have a significant impact

In order to avoid rain leakage and rust, the entire equipment needs to be painted and anti-corrosion, which consumes a lot of manpower and material resources, resulting in high overall costs, and the welded integrated structure is not conducive to later maintenance and product upgrades.
