Description

An environmentally friendly pulse dust collector

technical field

The utility model relates to the field of grain screening, in particular to a pulse dust collector.

Background technique

In the process of grain storage or seed processing, it is necessary to use cleaning equipment to screen and remove heavy impurities, light impurities and moldy grains mixed in grains.

In traditional air separation specific gravity cleaning equipment, materials generally pass through a vertical air sieve or a horizontal air sieve, and then enter the specific gravity table for specific gravity separation, or enter into grading screening. In order to carry out the air selection, the cleaning equipment is generally equipped with a spiral dust collector, but the spiral dust collector can only filter dust particles above 10 microns, and a large amount of smoke will be blown out of the air outlet of the fan, which cannot meet the national environmental protection monitoring requirements.

Utility model content

The technical problem to be solved by the utility model is to provide a pulse dust collector which can further reduce the smoke and dust content in the exhaust gas of the spiral dust collector.

The technical scheme adopted by the utility model is: a pulse dust collector, which comprises a casing, an air inlet arranged on the casing, a dust collecting drawer arranged at the bottom of the side of the casing, a pulse valve arranged in the casing, and an air inlet arranged on the casing. The dust filter cartridge connected with the pulse valve;

In the utility model, the inner space of the casing is divided into an air inlet chamber and a dust removal chamber through a partition plate in the casing, the pulse valve is arranged in the air inlet chamber, the dust removal filter cartridge is arranged in the dust removal chamber, and the dust collecting chamber is arranged in the dust collecting chamber. The drawer is located at the bottom of the dust chamber.

The pulse valve of the utility model is arranged on the partition between the air inlet cavity and the dust removal cavity.

One end of the dust filter cartridge of the utility model is fixed on the partition plate and communicated with the pulse valve, and the other end is fixed on the inner wall of the casing.

The dust removal filter cartridge of the utility model is arranged obliquely, and one end connected with the pulse valve is higher than the other end.

In the utility model, an equipment cavity is separated from the lower end of the air inlet cavity by a partition plate, a centrifugal fan is arranged in the equipment cavity, and the centrifugal fan and the air inlet cavity are communicated with the air inlet cavity through the ventilation holes arranged on the partition plate.

The dust-removing chamber of the utility model is in the shape of a funnel, and the dust-collecting drawer corresponds to the bottom outlet of the dust-removing chamber.

The shell of the utility model is square.

The positive effect of the utility model is as follows: the utility model is connected with the air outlet of the spiral dust collector, and the gas discharged from the spiral dust collector is further dedusted through the pulse valve and the dust removal filter cartridge, so that the exhaust gas has a lower soot content and is more efficient. Meet the national environmental protection requirements. At the same time, it is equipped with a centrifugal fan, which can increase the ventilation volume and realize a larger ventilation volume in the case of a small volume. The utility model has compact structure and small volume, and is convenient to be matched with other equipment of the cleaning machine.

Detailed ways

As shown in Figures 1 and 2, the utility model includes a square shell 1, an air inlet 2 arranged on the upper end of the side wall of the shell 1, a dust collection drawer 3 arranged at the bottom of the side of the shell 1, The pulse valve 5 in 1 and the dust filter cartridge 6 communicated with the pulse valve 5. The air inlet 2 can be communicated with the air outlet of the spiral dust collector to collect the gas discharged from the spiral dust collector and enter the utility model for further dust removal work, so that the final exhaust gas smoke and dust are less and meet the national environmental protection requirements.

In the casing 1, the inner space of the casing 1 is divided into an air inlet chamber 4, a dust removal chamber 7 and an equipment chamber 9 by a partition plate. The pulse valve 5 is installed in the space between the air inlet chamber 4 and the dust removal chamber 7. The separator is located in the air inlet chamber 4 , the dust filter cartridge 6 is arranged in the dust chamber 7 , one end of which is fixed on the separator and communicated with the pulse valve 5 , and the other end is fixed on the inner wall of the housing 1 . A centrifugal fan 8 is arranged in the equipment cavity 9 , and there are ventilation holes on the partition between the equipment cavity 9 and the air inlet cavity 4 , and the centrifugal fan 8 communicates with the air inlet cavity 9 through the ventilation holes.

The dust-removing filter cartridge 6 is arranged obliquely, and one end connected with the pulse valve 5 is higher than the other end. Correspondingly, it is used to collect the smoke and dust after being screened by the pulse valve 5 and the dust filter cartridge 6, and the dust collection drawer 3 can be pulled out of the housing 1, so that the smoke and dust in the dust collection drawer 3 can be cleaned regularly, and the operation is simple and convenient.

The above embodiments are only used to illustrate the technical solutions of the present invention, but not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that the foregoing embodiments can still be used for The recorded technical solutions are modified, or some technical features thereof are equivalently replaced; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions in the embodiments of the present invention.
