Description

A self-pressurized back-blowing bag dust collector

Technical Field

The utility model belongs to the technical field of bag dust collectors, in particular to a self-pressure back-blowing bag dust collector.

Background Art

The dust bag is the heart of the bag filter, generally called the dust bag or dust filter bag. The dust bag is the key part of the operation of the bag filter. Usually, the cylindrical filter bag is hung vertically in the dust collector. The fabric and design of the dust bag should strive for high-efficiency filtration, easy dust removal and durability. At the same time, the bag filter is often equipped with a backflush mechanism, which is usually realized by pulses and fans. The pulse backflush has a good effect, but the large impact force will affect the service life of the filter bag, while the fan backflush will effectively protect the filter bag.

The existing self-pressure back-blowing bag dust collector uses the self-pressure wind force generated by the back-blowing machine to back-blow the dust filtered on the surface of the filter bag, so as to clean the filter bag. In the back-blowing process, since the airflow discharge port is located at the upper end of the filter bag, the airflow will gradually advance from the upper end to the lower end of the filter bag after it is discharged. During the advancement process, the airflow flow space becomes larger, which will cause the airflow velocity to decrease, thereby affecting the cleaning rate of the filter bag and the back-blowing effect. Therefore, a self-pressure back-blowing bag dust collector is urgently needed to solve the above problem.

In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

As shown in Figures 1, 4 and 5, a self-pressure back-blowing bag dust collector includes a dust removal tank 1, a back-blowing mechanism 6 is installed on one side wall of the dust removal tank 1, and a lifting assembly 8 is arranged on the back-blowing mechanism 6, and the lifting assembly 8 includes: a branch pipe 801, the branch pipe 801 is fixedly connected to the back-blowing mechanism 6; a telescopic folding sleeve 802, the telescopic folding sleeve 802 is fixedly connected to the discharge port of the branch pipe 801; a guide plate 804, the guide plate 804 is fixedly connected to the bottom end of the telescopic folding sleeve 802; a nozzle 805, the nozzle 805 is distributed in a circular shape on the outer wall of the guide plate 804; an electric push rod 803, the fixed part of the electric push rod 803 is fixedly connected to the back-blowing mechanism 6, the output end of the electric push rod 803 is fixedly connected to the guide plate 804, and the electric push rod 803 has two groups.

The specific operations are as follows:

During the backblowing process, the electric push rod 803 can drive the telescopic folding sleeve 802 to extend and retract, thereby changing the position of the guide plate 804 to make it move in the filter bag 10. During the movement, the self-pressurized airflow ejected from the nozzle 805 can backblow and clean the accumulated dust on the surface of the filter bag 10. During the backblowing cleaning process, since the distance between the nozzle 805 and the filter bag 10 does not change, the ejected airflow can be ensured to act on the surface of the filter bag 10 at a higher flow rate, thereby backblowing and cleaning the dust on the surface of the filter bag 10, which can effectively improve the backblowing cleaning effect and cleaning efficiency of the device.

As shown in Figures 1 to 3, as an embodiment, the back-blowing mechanism 6 includes: a supporting plate 601, which is fixedly connected to a side wall of the dust removal tank 1; a back-blowing blower 602, which is fixedly connected to the upper end of the supporting plate 601; a guide pipe 603, which is fixedly connected to the output port of the back-blowing blower 602 and is located inside the dust removal tank 1; and a shunt pipe 604, which is fixedly connected to the guide pipe 603 and forms a "W"-shaped structure with the guide pipe 603.

The specific operations are as follows:

When the filter bag 10 is back-blown and cleaned, the self-pressure wind force generated by the back-blowing blower 602 enters the diversion pipe 604 through the guide pipe 603 and is diverted and enters the nozzle 805 through the branch pipe 801, the telescopic folding sleeve 802, and the guide plate 804 to be sprayed out, thereby acting on the filter bag 10.

As shown in Figure 1, as an implementation mode: an air inlet pipe 2 is welded to the bottom end of one side wall of the dust removal tank 1, an exhaust pipe 7 is welded to the upper end of the side wall of the dust removal tank 1 opposite to the air inlet pipe 2, and connecting flanges are provided at one end of the exhaust pipe 7 and the air inlet pipe 2; a collecting bucket 5 is formed at the bottom end of the dust removal tank 1, and the collecting bucket 5 is a conical structure; a discharge pipe 3 is formed at the bottom end of the collecting bucket 5, and a solenoid valve 4 is installed on the discharge pipe 3 by bolts.

The specific operations are as follows:

The dust-containing gas enters the dust removal tank 1 through the air inlet pipe 2, and the gas after dust removal by the filter bag 10 is discharged through the exhaust pipe 7. The collecting bucket 5 can collect the dust cleaned by backblowing, and the collected dust can be discharged from the dust removal tank 1 through the discharge pipe 3. The solenoid valve 4 controls the on-off of the discharge pipe 3.

As shown in Figures 1 to 3; as an implementation method: a partition 9 is fixed near the upper end of the dust removal tank 1, five groups of filter bags 10 are distributed in a circular pattern on the partition 9, and a telescopic folding sleeve 802 and a guide plate 804 are located in the filter bag 10.

The specific operations are as follows:

The filter bag 10 can filter dust in the dust-laden gas, and the partition plate 9 provides an installation position for the filter bag 10 .

In summary, the working principle of the self-pressure back-blowing bag dust collector is to install and fix the device and connect it to an external power supply. During use, the dust-containing gas enters the dust removal tank 1 through the air inlet pipe 2. At this time, the filter bag 10 filters the dust in the dust-containing gas, and the gas after dust removal by the filter bag 10 is discharged through the exhaust pipe 7. When the filter bag 10 needs to be back-blown and cleaned after the device has been used for a period of time, the back-blowing blower 602 is controlled to work, and the self-pressure wind force generated by it enters the diversion pipe 604 through the guide pipe 603 and is diverted and enters the nozzle 805 through the branch pipe 801, the telescopic folding sleeve 802, and the guide plate 804 to be sprayed out, and then acts on the filter bag 10. During the back-blowing process, the electric push rod 803 The telescopic folding sleeve 802 can be driven to extend and retract, thereby changing the position of the guide plate 804 and making it move inside the filter bag 10. During the movement, the self-pressurized airflow ejected from the nozzle 805 can back-blow and clean the dust accumulated on the surface of the filter bag 10. During the back-blow and clean process, since the distance between the nozzle 805 and the filter bag 10 remains unchanged, the ejected airflow can be ensured to act on the surface of the filter bag 10 at a higher flow rate, thereby back-blow and clean the dust on the surface of the filter bag 10, which can effectively improve the back-blow and clean effect and cleaning efficiency of the device. The back-blown dust falls into the collecting bucket 5 for collection, and then the discharge pipe 3 is opened through the solenoid valve 4, and the collected dust is discharged through the discharge pipe 3.

Many modifications and variations will be apparent to those of ordinary skill in the art.
