Description

Technical Field

[0001] The utility model relates to a dust collector, in particular to a pulse dust collector with a screening structure, belonging to the technical field of dust collectors. Background Art

[0002] A large amount of dust will be generated during the feed processing, which will not only pollute the environment but also cause harm to human health. Pulse dust collector is a kind of equipment used for air pollution control. It can effectively filter and remove dust in the air by removing dust attached to the filter medium (bag or filter cartridge) by blowing compressed air. Pulse dust collector is suitable for ceramics, chemical, electronics, steel, cement and other industries, and is widely used in dust control in feed processing and other industries. It can also be widely used in various industrial production processes, providing strong support for enterprises to solve dust pollution problems. When using this dust collector, it is also necessary to maintain and service the pulse cleaning system to ensure its normal operation.

[0003] However, the existing pulse dust collectors still have certain problems. Some existing pulse dust collectors used in feed processing do not have a screening structure, which makes dust filtering difficult. In feed processing, it is inevitable that there will be dust particles of different sizes. If the large particles of dust are not screened out first, the pulse device will easily be blocked, requiring staff to clean it many times, wasting a lot of time, resulting in the cancellation of filtering efficiency and unstable operation.

[0004] Therefore, there is an urgent need to improve the pulse dust collector with a screening structure to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of the utility model is to provide a pulse dust collector with a screening structure. When dust gas is inhaled, the dust gas passes through a square tube and enters a filtering square groove arranged in the square tube. By starting the vibration source equipment, the dust particles of different sizes are collected in a dust collecting box after vibration screening through three layers of filter screens. The coarsely screened dust gas then flows to the pulse dust collector through air holes, which greatly improves the efficiency of dust removal and does not cause blockage of the pulse device due to large particles of dust. The utility model has a simple structure and is very practical.

[0006] In order to achieve the above-mentioned purpose, the main technical scheme adopted by the utility model includes: comprising a square tube, a filter square groove is slidably connected on the inner wall of the square tube, three filter screens are clamped in the filter square groove, and the three filter screens are symmetrically arranged.

The through hole No. 1 and the through hole No. 2 are connected, a dust box is clamped on the through hole No. 2, and the lower end face of the filter square groove is connected to a vibration component for vibrating the filter square groove.

[0007] Preferably, the vibration assembly includes a No. 1 spring and a vibration source device component, one end of the No. 1 spring is fixedly connected to the lower end surface of the filter square groove, and the other end of the No. 1 spring is fixedly connected to the upper end surface of the vibration source device component.

[0008] Preferably, buffer columns are fixedly connected to both side walls of the vibration source device, and a No. 2 spring is fixedly connected to one end of the buffer column away from the vibration source device. Spring columns are fixedly connected to both inner side walls of the square tube.

[0009] Preferably, one end of the No. 2 spring away from the buffer column is fixedly connected to the inner top surface of the spring column, and the spring column is slidably connected to the buffer column.

[0010] Preferably, rubber pads are provided on the inner side walls of the No. 1 through hole and the No. 2 through hole.

A No. 1 through hole 4 is provided on one side of the filter square groove 2, and a No. 2 through hole 5 is provided on one side of the square tube 1. The No. 1 through hole 4 and the No. 2 through hole 5 are connected. Rubber pads 13 are provided on the inner walls of the No. 1 through hole 4 and the No. 2 through hole 5.
