Description

A bag filter

technical field

The utility model relates to the technical field of chemical equipment, in particular to a bag filter.

Background technique

The bag filter is the most commonly used dust removal device at present. Its working mechanism is: the coarse particles in the dust-containing gas collide with the inner wall of the dust-removing bag and fall directly into the ash hopper, and the fine particles in the dust-containing gas are filtered through the dust-removing bag, thereby realizing the dust removal of the dust-containing gas. However, the dust accumulation on the bag is difficult to clean up during the operation of the bag filter of the prior art, which brings great inconvenience to continuous production. Therefore need badly a kind of bag filter that can conveniently remove dust.

Utility model content

The technical problem to be solved by the utility model is to provide a bag filter that is easy to use, has good dust removal effect and is easy to clean.

A bag filter, characterized in that: at least two dust bags are arranged on the upper side of the dust collector, an air inlet is arranged on the lower side of the dust collector, an air outlet is arranged on the upper side of the dust collector, and an air outlet is arranged on the upper side of the dust collector. A sealed door is set on the side of the lower part of the dust collector, a through hole is set in the middle of the sealed door, a sealing cover is set in the through hole, a filter screen is set on the lower part of the dust collector, and a dust leakage port is set on the filter screen. There is an inverted cone-shaped ash hopper connected to the lower part of the dust collector, a valve is arranged at the lower end of the inverted cone-shaped ash hopper, and a support frame is evenly arranged around the dust collector; The hole passes through the matching dust removal pipe, and the dust removal pipe can pass through the through hole. At the other end of the dust removal pipe, there is a hollow support tube in the middle. The top of the suction pipe is provided with a suction head.

A blower device is arranged at the inner upper end of the dust remover.

The filter screen is detachable.

The utility model has the advantages of:

The utility model has the advantages of simple structure, convenient operation, simple opening of the airtight door, cleaning dust accumulated on the cloth bag by using a vacuum cleaner, low maintenance cost, greatly reducing labor burden, can be widely used, and has certain market promotion value.

detailed description

In order to better understand the technical solution of the utility model, the technical solution provided by the utility model will be described in detail below in conjunction with the accompanying drawings. The following example is only used to further illustrate the utility model, but should not be interpreted as the limitation of the utility model.

A bag filter, as shown in Figures 1-2, at least two dust bags 4 are arranged on the inner upper side of the dust collector 1, and an air inlet 2 is arranged on the lower side of the dust collector 1, and an air inlet 2 is arranged on the upper side of the dust collector 1. An air outlet 3 is provided on the side, a sealing door 8 is provided on the lower side of the dust collector 1, a through hole 8-1 is provided in the middle of the sealing door 8, and a sealing cover 8-2 is provided in the through hole 8-1. The lower part of the device 1 is provided with a filter screen 5, and an ash leakage port 5-1 is arranged on the filter screen 5, and an inverted cone-shaped ash hopper 6 connected with the lower part of the dust collector 1 is provided under the filter screen 5. The lower end of the ash bucket 6 is provided with a valve 6-1, and a support frame 7 is evenly provided around the dust collector 1; a vacuum cleaner 12 is provided as a set, and the dust collector 12 is provided with a dust removal pipe whose outer diameter matches the inner diameter of the through hole 8-1. 11. The dust removal pipe 11 can pass through the through hole 8-1, and the other end of the dust removal pipe 11 is provided with a central hollow support pipe 10, and on the support pipe 10 is provided with a central hollow telescopic dust suction pipe 10-1 , the top of the retractable dust suction pipe 10-1 is provided with a dust suction head 9.

The inner upper end of the dust remover 1 is provided with a blower device.

The filter screen 5 is detachable.

During specific use, as shown in Figure 1, dusty air enters the dust collector 1 from the air inlet 2 provided on the lower side of the dust collector 1, and when passing through the filter screen 5, large particles are blocked from falling into the inverted cone-shaped ash hopper 6. Then the preliminarily filtered air passes through the dust-removing cloth bag 4, and the dust is blocked and falls, and falls into the inverted cone-shaped ash hopper 6 from the ash leakage port 5-1 provided on the filter screen 5. The clean air after dedusting is discharged from the air outlet 3 . During use, dust often accumulates on the dust-removing bag 4, which will affect the dust-removing effect. At this time, the airtight door 8 can be opened, the dust removal pipe 11 can be passed through the through hole 8-1 on the airtight door 8, the dust suction head 9 can be aligned with the inner side of the dust bag 4, the vacuum cleaner 12 can be opened, and the middle part set on the support pipe 10 The hollow telescopic dust suction pipe 10-1 moves up and down with the dust suction head 9 while moving up and down, and the dust accumulation inside the dust removal bag 4 is cleaned up. Then take out the support pipe 10 and the dust suction head 9, and close the airtight door 8 to continue working. The dust in the inverted cone ash hopper 6 can be discharged after the valve 6-1 is opened.

The utility model has the advantages of simple structure, convenient operation, simple opening of the airtight door, cleaning dust accumulated on the cloth bag by using a vacuum cleaner, low maintenance cost, greatly reducing labor burden, can be widely used, and has certain market promotion value.
