Description

A filter cartridge dust collector

technical field

The utility model belongs to the field of dedusting devices, in particular to a dedusting device used for grain processing and transportation.

Background technique

At present, bag filter is widely used in grain transportation and processing to filter and collect dust. In the prior art, there is a bag filter, the structure of which includes a vertical dust removal cylinder, one end of the dust removal cylinder is provided with an air inlet, and the other end is provided with a fitting port for the bag, and the fitting port is provided with a set for collecting Dust bag. Its shortcoming is that the filter area of a single cloth bag set on the set port of the dust removal cylinder is very small. For example, the filter area of a cylindrical standard cloth bag with a length of 2m and an outer diameter of 120mm is about 0.75m ² , and its working efficiency is too high. Therefore, when dealing with dust with a large air volume, it is usually necessary to increase the size of the dust collector or increase the number of dust collectors to meet the dust removal requirements of the process, resulting in a large footprint and a complex structure for the bag filter. Set outside the metal frame, the cloth bag is likely to rub against the metal frame during the cleaning and disassembly process, resulting in wear and tear, which is not easy to clean. When the bag is damaged and needs to be replaced, it will cause secondary dust and pollute the environment.

On the cylinder, the filtered clean air enters the clean air chamber through the opening of the filter cylinder, and is discharged through the air outlet under the suction of the fan; when the filter cylinder needs to be cleaned, the solenoid valve opens, and the compressed air in the air storage bag enters The spray rod sprays high-pressure air to each corresponding filter cartridge through the nozzle, so that the dust adsorbed on the surface of the filter cartridge vibrates and falls into the dust hopper. Compared with the prior art, the beneficial effect of the utility model lies in that: the deflector first blocks the dust particles with a larger particle size, and then the filter cartridge filters the dust in the dust-containing gas, and the dust removal effect is good; through the pulse controller The opening interval and opening time of the solenoid valve can be adjusted. When the filter reaches a fixed time and the filter cartridge needs to be cleaned, the solenoid valve is opened. After the filter cartridge is cleaned, the solenoid valve is closed again to realize automatic control of dust removal and high working efficiency. The device has a compact structure and Small footprint, easy to clean, high dust removal efficiency, environmentally friendly and clean. The device can be used for filtering and collecting dust during grain transportation and processing.

As a further improvement of the utility model, the filter cartridges in the dust filter chamber are distributed in a rectangular array, and the upper end of each filter cartridge is fixedly connected with the partition plate. The filter cartridges are distributed in a rectangular array with a large filtering area, which can fully filter the dust. The number and size of the filter cartridges can be freely adjusted according to the required filtration accuracy, and the corresponding filter materials can be selected.

As a further improvement of the utility model, the filter cartridge is a folded filter cartridge, and a seal is provided at the connection between the upper end of the filter cartridge and the partition plate. The folded filter cartridge is adopted, which has a large filtering area and good filtering effect. The upper end of the filter cartridge is sealed with the partition plate to prevent dust from entering the clean air room.

As a further improvement of the present utility model, several horizontal spray bars with axes parallel to each other are arranged side by side in the clean air chamber. The rod is provided with several air outlets, and each air outlet is connected with the air inlet of the nozzle. Each nozzle on the spray rod corresponds to each filter cartridge in the dust filter chamber. After the solenoid valve is opened, the compressed air in the air storage bag is released to clean the filter cartridge.

As a further improvement of the utility model, the dust collecting hopper is an inverted cone, and the lower end of the dust collecting hopper is provided with a discharge locker. The unloading air lock can continuously remove the dust collected in the dust hopper in time and play a role of air tightness.

As a preferred solution of the present utility model, a supporting frame is fixedly connected to the side of the dust collecting hopper.

As a further improvement of the utility model, an inspection door is provided on the top of the dust removal box. After opening the inspection door, it is convenient to inspect and maintain the inside of the dust removal box.
