Description

a dust collector

technical field

The utility model relates to a dust remover, in particular to a dust remover used for removing solids in air flow, and belongs to the technical field of dust removal equipment.

Background technique

Dust collectors are widely used and often involve mining, metallurgy, chemical industry, pharmaceuticals, building materials, light industry and other fields. For example, the Chinese invention patent with the application number 201110108073.9 discloses a dust collector, which includes: an upper box with an air outlet on its right side; There is a partition in the middle, which divides the middle box into a left part and a right part. A filter bag frame is set in the left part of the middle box, and a filter bag is arranged on the filter bag frame. In the upper part of the right part of the middle box, A fan is provided, and the lower part is provided with an air inlet; the lower box is arranged on the lower side of the middle box. The dust collector uses a pulse controller to clean the filter bag, and uses a venturi tube to guide the secondary air to strengthen the cleaning of the filter bag. However, in actual use, it is found that the device has a good purification effect, but the treatment efficiency is very low.

Utility model content

The purpose of the utility model is to provide a dust collector to solve the problem of low processing efficiency of the dust collector.

The above-mentioned technical purpose of the utility model is achieved through the following technical solutions:

A dust collector, comprising a box body, an air inlet pipe and an induced draft fan, the air inlet pipe is connected to the air inlet in the middle and upper part of the box body, a filter screen is arranged horizontally above the air inlet in the box body, and the filter screen A porous partition is installed above the porous partition, and a number of blowing pipes connected to the pulse compressed air source are installed above the porous partition. The bottom of the blowing pipe is provided with a number of blowing holes corresponding to the holes on the porous partition. An air outlet is provided on the upper part of the box and on the opposite side of the air inlet, and the air outlet is connected with the suction pipe of the induced draft fan.

When the above technical solution of the utility model is implemented, due to the effect of the induced draft fan, the air containing a lot of dust enters the box from the air inlet. At this time, due to the sudden expansion of the air flow volume, the flow velocity decreases, and part of the dust sinks from the air flow under its own gravity. Most of the remaining dust and particles are caught by the filter screen, and the air passes through the filter screen to complete the filtration. After filtering for a period of time, the filter screen is easily blocked. Therefore, the utility model is also provided with a blowback mechanism for cleaning the filter screen. The blowback mechanism includes a porous baffle and a blowpipe. The blowing pipe is connected with the air blowing device of the pulse source, and the hole of the blowing pipe corresponds to the hole of the partition plate. After filtering for a period of time, the wind from the pulse source blows to the surface of the mesh screen, and the mesh screen will vibrate at a certain frequency, thereby Clean the mesh of the filter screen that is blocked by dust.

As a preference of the above technical solution, the lower part of the box is cone-shaped.

As a preference of the above technical solution, an auger-type ash outlet is installed at the bottom of the box.

As an optimization of the above technical solution, the utility model is composed of a first box body and a second box body connected in series, and is provided with a first induced draft fan and a second induced draft fan; the dust collector also includes a connecting pipe; the inlet The air duct is connected to the upper air inlet of the first cabinet, the air outlet of the first cabinet is connected to the suction pipe of the first induced draft fan, the outlet pipe of the first induced draft fan is connected to the air inlet of the second cabinet, and the second cabinet The air outlet of the body is connected to the suction pipe of the second fan, and the outlet pipe of the second fan discharges the atmosphere.

In summary, the utility model has the following technical effects:

The utility model separates the air and the dust through the mesh screen. Compared with the separation by the filter bag, the utility model has the advantages of large processing capacity and high processing efficiency. Moreover, the filter bag is easier to block holes than the mesh screen, and it is more difficult to handle after the holes are blocked. Although the processing capacity of the filter bag is small and the processing efficiency is low, the processing effect of the filter bag is relatively good. Therefore, the design of the utility model is designed to ensure the processing effect, and the utility model is arranged in series. After the utility model is arranged in series, the effect of secondary dust removal is no less than that of filter bag treatment, and it also has the advantages of large processing capacity and high processing efficiency. Therefore, the designer of the utility model is designed to ensure the filtering efficiency and filtering effect, and a blowback mechanism is also provided to the filtering screen. During the dust removal process, due to the blowback effect of the pulse source, the filter screen vibrates, which can make the filter screen clean while filtering, and at the same time, the vibrating filter screen can also effectively prevent the holes from being blocked.
