Description

A mobile manual pulse blowback welding fume purifier

technical field

The utility model relates to the technical field of welding fume purifiers, in particular to a mobile manual pulse blowback welding fume purifier.

Background technique

In recent years, with the rapid development of my country's industry, the environmental protection awareness of the country and the people is also constantly increasing, and the country's environmental protection emission standards are becoming more and more stringent. Welding process is an indispensable link in modern manufacturing industry. A large amount of metal oxide dust will be generated during welding. Most of the dust particles are in the micron level, which not only pollutes the working environment, but also pollutes the working environment for a long time. Working under low conditions can easily cause pneumoconiosis and endanger the physical and mental health of workers.

At present, the commonly used dust removal equipment is: 1. Electrostatic dust collector: Although the filtration accuracy of electrostatic dust collector is relatively high, when the metal oxide accumulates to a certain extent, the electrode plates will break down and discharge, which is prone to danger; 2. Cloth bag Type dust collector: its running resistance is large, it needs to be replaced frequently, and the maintenance cost is high; 3. Cartridge type dust collector: its structure is simple and easy to maintain, but the height of the previous filter cartridge dust collector is too high, and the fan is placed on top. The operation noise of the equipment is high, and the center of gravity of the equipment is too high, so it is easy to overturn during the moving process, posing safety hazards, and the air duct path is long, the wind loss is large, and the performance of the equipment is relatively low.

Utility model content

The utility model aims at the above problems, improves the existing cartridge type dust collector, and designs a welding fume purifier with simple structure, good control effect on welding fume and low operating cost.

In order to solve the above problems, the technical solution of the utility model is as follows: a mobile manual pulse blowback welding fume purifier mainly includes a shell, a cavity I, a cavity II and a cavity III, and the top of the shell is installed with Air inlet and handle, casters are installed at the bottom of the shell, and a control panel is also installed on the shell, an air bag and a pulse valve are installed in the cavity I, a filter cartridge is installed in the cavity II, and the cavity II is located Below the cavity I, a fan assembly is installed in the cavity III, and an air outlet is installed at the connection between the fan assembly and the casing.

Further, a muffler assembly is installed at the air outlet.

Further, the filter cartridge adopts a paper-based film-coated quick-release filter cartridge.

Further, the filter cartridge and fan assembly are vertically installed on the casing.

Further, the top of the cavity I is a sloped structure.

The beneficial effects of the utility model:

(1) The utility model adopts the differential pressure sensor and related electrical components to realize intelligent manual control of backflushing, which can reduce the labor intensity of workers cleaning dust;

(2) The mobile manual pulse back-blowing welding fume purifier provided by the utility model has high dust removal precision, low noise, is movable and easy to use, is not easy to dump, and has strong applicability;

(3) The mobile manual pulse blowback welding fume purifier provided by the utility model has the characteristics of simple structure and small volume, convenient production and use, and low cost.

detailed description

As shown in Figure 1-Figure 5, a mobile manual pulse blowback welding fume purifier mainly includes a housing 1, a cavity I12, a cavity II13 and a cavity III14, and an air inlet is installed on the top of the housing 1 3 and handle 4, casters 6 are installed on the bottom of the housing 1, and a control panel 2 is also installed on the housing 1. The air bag 10 and the pulse valve 11 are installed in the cavity I12, and the filter is installed in the cavity II13. Cylinder 5, cavity II13 is located below cavity I12, fan assembly 8 is installed in the cavity III14, and air outlet 9 is installed at the connection between fan assembly 8 and housing 1. In addition, air inlet 3 can be connected with flexible suction The air arm can rotate 360° to improve the flexibility of the equipment. The handle 4 installed on the top of the housing 1 and the casters 6 at the bottom of the housing 1 facilitate the movement of the equipment. The top of the chamber I12 is a slope structure.

When in use, the fan assembly 8 is turned on, and the external smoke and dust gas enters the interior of the equipment from the air inlet 3 through the inclined surface outside the cavity I12, and then is filtered by the filter cartridge 5, and is sucked into the fan assembly 8. The noise reduction treatment of the component 7 is discharged to the external environment through the air outlet 9, and the caster 6 is installed at the bottom of the housing 1, and the material of the caster is preferably rubber, which is convenient for mobile use.

When a certain amount of welding fume dust has accumulated outside the filter cartridge 5, the pressure difference in the internal cavity of the equipment will be relatively large. When the pressure sensor set value is reached, the equipment will automatically alarm, prompting for manual blowback, and manually press the start button. The gas stored in the gas bag 10 is blown away from the filter cartridge 5 through the pulse valve 11 to blow the accumulated welding fume and dust away from the filter cartridge 5, which greatly improves the cleanliness of the outer surface of the filter cartridge 5 and enables the equipment to continue to operate normally.

The specific implementation of the utility model has been described in detail above in conjunction with the accompanying drawings, but the utility model is not limited to the above-mentioned implementation, within the knowledge of those skilled in the art, you can also Make various changes.

The above specific embodiments are only used to explain the concept of the utility model, rather than to limit the protection of the utility model rights. Any insubstantial changes made to the utility model by using this concept fall within the protection scope of the utility model.
