Description
Technical Field
The utility model belongs to the technical field of dust collectors, and particularly relates to a dust collector of an air shower.
Background
In the working space with large dust such as brick factories, workers often stick dust, which affects health and is not sanitary. There is currently no solution specifically directed to this situation.
The filter element is a filter bag (a framework is arranged in a filter cloth bag, which is the known technology) or a dust remover of a filter cartridge, one of the key factors of the dust removal efficiency is the effect of back-flushing and dust removing after dust is accumulated on the surface of the filter bag or the filter cartridge, and the most key component for ensuring the dust removing effect to meet the design requirement is a back-flushing nozzle.
Dust collectors of other companies in the market at present use circular pipes 23 with different diameters and lengths of 30-50 mm as back-blowing nozzles as shown in fig. 16, the back-blowing gas flow from common nozzles is narrow as shown in fig. 16 (a), the narrow injection effect of high-pressure gas flow of the common nozzles is not obvious, the amount of gas injected into a cloth bag is small, the venturi nozzles are installed at the inlets of the cloth bag as shown in fig. 16 (b), the gas flow is limited, and the back-blowing effect is very poor as shown in fig. 16 (c), and is mainly shown in the following steps: the bag is not completely pasted during the ash removal, the blowing direction deviates to blow the cloth bag, and the shaking amount is small due to the fact that the quantity of gas entering the cloth bag is small and the cloth bag is not expanded obviously, so that the ash removal effect is not obvious and the like.
The filter element is a filter bag or a filter cartridge dust remover, one of the key factors of the dust removal efficiency is the effect of back-blowing and dust removal from the inlet of the filter bag after dust is deposited on the surface of the filter bag or the filter cartridge, so as to ensure that the dust removal effect reaches the design requirement,
the tightness of the blow-back pipe socket for the connection between the air supply solenoid valve and the blow-back pipe is very important for this.
At present, no back flushing pipe socket commodity of the design exists in the market, dust collectors manufactured by other companies have various and crude connections between a back flushing pipe and an electromagnetic valve, and the defects of the crude connection modes are mainly shown as follows: air leakage is very serious, and the dust cleaning effect of the cloth bag or the filter cylinder is seriously influenced.
The air leakage between the air cylinder and the electromagnetic valve is easy to occur.
