Description

A self-cleaning bag dust removal device

Technical Field

The utility model relates to the field of bag dust removal equipment, in particular to self-cleaning bag dust removal equipment.

Background technique

Bag dust collector, a dry filter, is a common dust removal equipment in industrial production processes. It is often used to capture fine, dry, non-fibrous dust. After a long period of operation, a thick layer of dust will adhere to the surface of the bag, which will affect the passage of airflow and reduce the dust removal effect. Therefore, it is necessary to remove the dust on the surface of the bag in time. The existing bag dust collector uses the method of spraying pulse airflow to remove dust. The pulse airflow is dispersed through the pipeline to multiple bags to blow off the dust. After the airflow is dispersed, its impact force is greatly weakened. In addition, the bag is long and can only blow the dust on the top of the bag. The dust below is difficult to clean, and the dust removal effect is not good.

Utility Model Content

In order to overcome the problems existing in the background technology, the utility model provides a self-cleaning bag dust removal device to solve the technical problem in the background technology that a lot of dust adheres to the surface of the bag and is difficult to clean.

To achieve the above purpose, the utility model is implemented through the following technical solutions:

A self-cleaning bag dust removal device comprises a box body 1, an ash hopper 2, an air inlet duct 3, an air outlet duct 4, a dust bag 5, and a cleaning mechanism 6; support feet 7 are installed around the bottom of the box body 1, the ash hopper 2 is installed at the bottom of the box body 1, and the ash hopper 2 is connected to the air inlet duct 3; a partition 8 is installed in the box body 1 to divide the box body 1 into an upper box body 101 and a lower box body 102, and the air outlet duct 4 is connected to the upper box body 101; through holes 9 are evenly opened on the partition 8, and dust bags 5 are installed at the bottom of the through holes 9; the cleaning mechanism 6 comprises a cylindrical grid 61, an eccentric shaft 62, and a motor 63; the cylindrical grid 61 is sleeved in the dust bag 5, and is transmission-connected to the motor 63 installed on the top of the box body 1 through the eccentric shaft 62.

Preferably, the air outlet pipe 4 is connected to a negative pressure pump 10 for forming air flow in the box 1 .

Preferably, a dust removal and ash discharge valve 11 is installed at the lower end of the ash hopper 2 to facilitate the discharge of dust in the ash hopper 2.

The beneficial effects of the utility model are as follows: the utility model vibrates and shakes off the dust on the surface of the dust bag through the cleaning mechanism, and drives the cylindrical grid frame to vibrate in the dust bag through the rotation of the eccentric shaft, thereby shaking off the dust. This method has a good dust removal effect and can remove all the dust on the dust bag, thereby realizing the self-cleaning function of the dust removal equipment, and there is no need to open the dust removal equipment for manual cleaning; at the same time, the cylindrical grid frame can also play a supporting role for the dust removal bag, to prevent the air pressure from flattening the dust removal bag when the dust removal equipment is working, causing the bag to lose its dust removal function.

Detailed ways

In order to make the purpose, technical solution and beneficial effects of the present invention clearer, the preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings to facilitate the understanding of technicians.

As shown in Fig. 1-3, a self-cleaning bag dust removal device includes a box body 1, an ash hopper 2, an air inlet duct 3, an air outlet duct 4, a dust bag 5, and a cleaning mechanism 6; support feet 7 are installed around the bottom of the box body 1, the ash hopper 2 is installed at the bottom of the box body 1, and the ash hopper 2 is connected to the air inlet duct 3; a partition 8 is installed in the box body 1 to divide the box body 1 into an upper box body 101 and a lower box body 102, and the air outlet duct 4 is connected to the upper box body 101; through holes 9 are evenly opened on the partition 8, and dust bags 5 are installed at the bottom of the through holes 9; the cleaning mechanism 6 includes a cylindrical grid 61, an eccentric shaft 62, and a motor 63, and the cylindrical grid 61 is sleeved in the dust bag 5, and is connected to the motor 63 installed on the top of the box body 1 through the eccentric shaft 62.

When the dust removal equipment is working, air containing dust and impurities enters the ash hopper 2 from the air inlet pipe 3. The heavier particles such as impurities hit the inner wall of the ash hopper 2 and automatically fall into the ash hopper 2 due to the action of gravity. The lighter dust moves upward into the lower box 102 with the air. The air enters the dust bag 5 from the outer wall of the dust bag 5. The dust is filtered and adsorbed on the outside of the dust bag 5. The clean air enters the upper box 101 from the inside of the dust bag 5 through the through hole 9 on the partition 8 and is discharged from the air outlet pipe 4. into the atmosphere; during the dust removal process, since the airflow flows from the outside of the dust bag 5 to the inside, the columnar grid 61 in the dust bag 5 supports the dust bag 5, preventing the dust bag 5 from being flattened by air pressure and losing its dust removal function; when cleaning the dust after the dust removal is completed, the motor 63 is started, and the motor 63 drives the eccentric shaft 62 to rotate, and the rotation of the eccentric shaft 62 drives the columnar grid 61 to vibrate in the dust bag 5, thereby shaking off the dust attached to the outer wall of the dust bag 5 and dropping it into the ash hopper 2. The columnar grid 61 vibrates in the dust bag 5, thereby shaking off the dust. This method has a good dust removal effect and can remove all the dust on the dust bag 5. At the same time, the columnar grid 61 can also support the dust bag 5, preventing the air pressure from flattening the dust bag 5 when the dust removal equipment is working, causing the bag to lose its dust removal function.

The air outlet pipe 4 is connected to a negative pressure pump 10 for forming an air flow in the box body 1. The negative pressure pump 10 can form a flowing air flow in the box body 1, thereby filtering dust in the air.

The lower end of the ash hopper 2 is provided with a dust removal and ash discharge valve 11 for discharging dust in the ash hopper 2. The dust stored in the ash hopper 2 can be conveniently discharged through the dust removal and ash discharge valve 11.

work process:

The air intake duct 3 of the dust removal equipment is installed in a production workshop such as a factory building, and the air in the workshop is dusted. The negative pressure pump 10 is started to make the dust-containing air in the factory flow outward and first enter the ash hopper 2. The heavier particles such as impurities hit the inner wall of the ash hopper 2 and automatically fall into the ash hopper 2 due to gravity. The lighter dust moves upward into the lower box 102 with the air. The air enters the dust bag 5 from the outer wall of the dust bag 5, and the dust is filtered and adsorbed on the outside of the dust bag 5. The clean air passes from the inside of the dust bag 5 through the through holes on the partition 8 9 enters the upper box body 101 and is discharged into the atmosphere from the air outlet pipe 4; during the dust removal process, since the air flow flows from the outside of the dust bag 5 to the inside, the columnar grid 61 in the dust bag 5 supports the dust bag 5 to prevent the dust bag 5 from being flattened by air pressure and losing the dust removal function; when cleaning the dust after the dust removal is completed, the motor 63 is started, and the motor 63 drives the eccentric shaft 62 to rotate. The rotation of the eccentric shaft 62 drives the columnar grid 61 to vibrate in the dust bag 5, so that the dust attached to the outer wall of the dust bag 5 is shaken off and falls into the ash hopper 2.

Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the utility model.
