Description

A Mechanical Vibrating Bag Dust Collector

technical field

The utility model relates to the field of dust collectors, in particular to a mechanical vibration bag type dust collector.

Background technique

The mechanical vibrating bag filter is a bag filter that uses a mechanical vibration device to periodically vibrate the filter bag for dust cleaning. It is widely used in petroleum, chemical, metallurgy, environmental protection, pharmaceutical and other industries. At present, conventional bag-type dust collectors mostly use upper part rapping or waist rapping to clean dust; the airflow direction adopts inner filter operation, and the dust-laden gas flows from the inside of the filter bag to the outside of the filter bag, and the dust is separated in the filter bag. During the operation of the equipment, the dust is easy to agglomerate, and the agglomerated dust adheres to the surface of the filter bag, which reduces the filtering air velocity of the equipment and increases the resistance of the equipment. Moreover, the pressure fluctuates greatly during the operation process, making it difficult to realize the smooth operation of the process equipment.

Contents of the invention

In order to solve the problems in the prior art, reduce dust agglomeration, reduce equipment operation resistance and pressure fluctuation, the utility model provides a mechanical vibration bag type dust collector.

The utility model provides a mechanical vibrating bag-type dust collector, which includes a casing, the top surface of the casing is provided with a purified gas outlet, and the side is provided with a dusty gas inlet, and the casing is provided with a flower plate and a filter bag. The upper end of the filter bag is fixed on the flower plate, and the lower end of the filter bag is fixed on the mechanical vibration device.

The position of the dusty gas inlet located on the side of the housing corresponds to the lower part of the filter bag.

A funnel-shaped ash hopper is also connected to the lower end of the shell, and a dust outlet is arranged below the ash hopper.

The mechanical rapping device is connected with the motor.

Compared with the prior art, the utility model has the following advantages:

1. The mechanical vibrating bag filter designed by this utility model has simple structure and convenient operation.

2. The mechanical vibrating bag filter designed by this utility model, because the dust-containing gas flows from the outside of the filter bag to the inside of the filter bag, the dust is filtered to the outside of the filter bag, and the dust is effectively reduced in the filter bag through the mechanical vibrating device. The agglomeration on the surface effectively reduces the adsorption of agglomerated dust on the surface of the filter bag, reduces the operation resistance of the equipment, and improves the production capacity of the equipment.

3. The mechanical rapping bag filter designed by this utility model has small pressure fluctuations during operation, which is conducive to the stability of equipment and related process operations.

4. In the mechanical rapping bag dust collector designed by the utility model, the filter bag is installed downward from the top of the dust collector, and the replacement of the filter bag and the maintenance of the equipment are convenient.

Detailed ways

Embodiment 1 Concrete structure of the present utility model

As shown in Figure 1, the mechanical rapping bag filter of the present utility model comprises a housing 1, the top surface of the housing 1 is provided with a purified gas outlet 2, and the side is provided with a dusty gas inlet 3, and the housing 1 is provided with Flower plate 5 and filter bag 4, the upper end of the filter bag 4 is fixed on the flower plate 5, and the lower end of the filter bag 4 is fixed on the mechanical rapping device 6. The opening side of the filter bag is connected to the flower plate, and the flower plate has an air outlet corresponding to the position of the filter bag mouth. The filter bag is installed downward from the top of the bag filter, which is easy and convenient to operate.

The position of the dust-laden gas inlet 3 located on the side of the housing 1 corresponds to the lower part of the filter bag 4, so that the dust-laden gas can make full use of the filter bag with a large area, and the dust removal efficiency is high.

A funnel-shaped ash hopper 9 is also connected to the lower end of the housing 1, and a dust outlet 8 is arranged below the ash hopper 9, which is beneficial to dust removal. The mechanical rapping device 6 is connected with a motor 7 .

The mechanical rapping device 7 is arranged at the bottom of the dust collector and can be a conventional structure. For example, the mechanical rapping device includes a rapping frame, a rocking bar and a crank mechanism. The rapping frame is connected with the inner side of the shell through the rocker, and connected with the motor through the crank mechanism, and the lower end of the filter bag is fixed on the rapping frame. In this way, the vibrating frame is driven by the motor to shake, and the vibrating frame drives the filter bag to shake, so that the dust on the filter bag can be separated, fall into the ash hopper, and be removed through the dust outlet.

The dust-laden gas enters the dust collector and flows from the outside of the filter bag 4 to the inside of the filter bag 4. The filtered purified gas passes through the filter bag and is discharged from the purified gas outlet 2 on the top, and the dust is captured on the outer surface of the filter bag 4. The collected dust The ash hopper 9 at the bottom of the dust collector is shaken by the mechanical rapping device 6 and discharged from the dust outlet 8.

The mechanical vibrating bag dust collector designed by the utility model has simple structure and convenient operation; it adopts the filtering method that the dust-laden gas flows from the outside of the filter bag to the inside of the filter bag, which reduces the operating resistance of the equipment and improves the production capacity of the equipment; effectively The agglomeration of dust materials is greatly reduced, and the adsorption of the agglomerated dust on the surface of the filter bag is effectively reduced; the pressure fluctuation is small during the operation, which is conducive to the smooth operation of the process equipment; the filter bag is installed from the top of the dust collector downward, and the filter bag It is convenient for replacement and equipment maintenance.
