Description

Technical Field

[0001] The invention relates to the technical field of bag dust collectors, and more specifically to a bag dust collector used for industrial waste gas treatment. Background Art

[0002] Industrial pollution refers to the pollution of the environment by waste gas, waste water and solid emissions generated in the process of industrial production. Pollution is mainly caused by the "three wastes" (waste water, waste gas and waste residue) and various noises in production, which can be divided into waste water pollution, waste gas pollution, waste residue pollution and noise pollution. Among them, industrial waste gas pollution, with the rapid development of industry, a large amount of waste gas will be generated in industrial production. If it cannot be properly treated, it will be discharged into the air, which will not only pollute the environment, but also seriously endanger human health.

[0003] Usually, the excellent filtering effect of bag dust collector on exhaust gas is used to purify industrial exhaust gas. The working principle of bag dust collector is mainly to input exhaust gas into the dust collector, and when the airflow passes through the bag, the bag filters the exhaust gas, so that impurities are left on the inner wall or outer wall of the bag. However, the existing bag dust collector still has the following defects:

[0004] The bags in the existing bag dust collector are mostly cylindrical and equidistantly arranged in the box structure. Usually, after the exhaust gas is filtered, a downward high-pressure airflow is input into the bag to clean the impurities left on the inner wall of the bag. However, the use of a single downward high-pressure airflow can avoid the impurities hidden in the woven grooves of the bag. The effect of this single-direction high-pressure airflow in removing impurities is not obvious. In the long run, it affects the actual filtering effect of the subsequent bag dust collector.

At the same time, the impurities falling to the bottom of the installation cylinder 18 are received and discharged through the impurity removal component.

[0035] See also Figure 1 , Figure 4 , Figure 5 , Figure 6 , Figure 7 as well as Figure 8 As another preferred embodiment of the present application, the auxiliary module includes a hollow tube 19, an exhaust structure and a cleaning structure. The hollow tube 19 is arranged on the dust removal box 2 and is connected to the mounting seat 17 at the end of the mounting tube 18 away from the air outlet.

[0037] In another specific situation of this embodiment, the second groove 34 is located on a side of the guide ring 24 close to the air outlet, and the second groove 34 and the first groove 32 are arranged vertically.

[0038] In actual application, when the No. 1 fan 4 is working, the external exhaust gas is input into the installation tube 18 along the air inlet barrel 5 and the air outlet, and the gas is transmitted from the inside of the installation tube 18 to the outside along the cloth bag 20 to achieve the filtering effect, and when the No. 1 fan 4 stops working, the driving component and the impurity removal component are switched to start working through the control console 3, so as to drive the exhaust structure to work. When the exhaust structure is working, the air in the hollow tube 19 can be input into the impurity removal ring 23 and the guide ring 24. The outgoing airflow is in a vertical state, and the airflow sprayed by the No. 1 nozzle 33 can enter the inner side along the outer side of the cloth bag 20, so as to flush out the impurities attached to the inner side of the cloth bag 20, and when the No. 2 nozzle 35 outputs the airflow, the detached impurities can be blown to the position of the air outlet and received by the impurity removal component. While the driving component controls the operation of the exhaust structure, it can control the movable arm 28, the guide ring 24 and the impurity removal ring 23 to reciprocate in the vertical direction, so as to realize the cleaning of impurities on the inner wall of the cloth bag 20 at different positions.

[0039] See also Figure 1 , Figure 4 , Figure 5 , Figure 6 , Figure 7 as well as Figure 8As another preferred embodiment of the present application, the exhaust structure includes a piston rod 27, a connector 26 and a hose 29. An input hole 31 and an output hole 30 are provided on the hollow tube 19. Both the input hole 31 and the output hole 30 are provided with a one-way valve.

[0041] It should be noted that the power element can be a stepper motor 13 or a servo motor. In the present embodiment, the stepper motor 13 is preferably a stepper motor 13. The stepper motor 13 is arranged on the dust storage box and its output end is connected to the driving roller 14. As for the specific model parameters of the stepper motor 13, the best choice can be made according to the actual situation, and no specific limitation is made here.

[0042] In actual application, the control console 3 controls the stepper motor 13 to be powered on and rotate reciprocatingly, thereby controlling the synchronous rotation of the drive roller 14, and then driving the drive arm 15 to swing continuously. Under the action of the push arm 16, the connecting head 26 and the piston rod 27 can be driven to reciprocate relative to the hollow tube 19, so that the outside air is input into the guide ring 24 and the impurity removal ring 23 along the hose 29, so that the impurities on the inner wall of the bag 20 can be removed and finally fall into the impurity removal component. When the piston rod 27 moves, the position of the movable arm 28 can also be adjusted to realize the adjustment of the position of the guide ring 24 and the impurity removal ring 23.

[0043] See also Figure 1-Figure 8 As another preferred embodiment of the present application, the impurity removal component includes an impurity box 8, a No. 2 fan 7 and a connecting box 10. The impurity box 8 and the No. 2 fan 7 are both arranged on the support base 1. The connecting box 10 is arranged on the dust removal box 2 and connects the air outlet and the mounting tube 18. One end of the connecting box 10 is connected to the impurity box 8, and the other end is connected to the No. 2 fan 7.

[0044] In a specific case of this embodiment, the impurity removal component further includes a plurality of partitions, which are arranged between the air outlet and the mounting cylinder 18 to isolate the impurities output by the mounting cylinder 18 from the exhaust gas input by the air outlet.

[0045] In another specific case of this embodiment, the partition includes a collecting box 9, an air intake channel 11 and an impurity removal channel 12. The collecting box 9 is arranged between the air outlet and the mounting tube 18. The air intake channel 11 and the impurity removal channel 12 are both arranged in the collecting box 9 and separated by a partition. The air intake channel 11 is connected to the connecting box 10.

[0046] When the No. 1 fan 4 is working to input the exhaust gas into the air inlet barrel 5, the exhaust gas in the air inlet barrel 5 can enter the mounting tube 18 along the air port and the air inlet channel 11. When the No. 1 nozzle 33 and the No. 2 nozzle 35 respectively guide the airflow to the outer wall and the inner wall of the cloth bag 20, the impurities on the inner wall of the cloth bag 20 can fall into the impurity removal channel 12 under the action of gravity and the traction of the airflow, and when the control console 3 controls the No. 2 fan 7 to be powered on and rotated, the airflow can be input into the connecting box 10. The airflow through the connecting box 10 can drive the impurities in the impurity removal channel 12 to move and finally discharge them into the impurity box 8.

[0047] How this application works:

[0048] By connecting the air inlet barrel 5 and the exhaust gas supply source, and controlling the No. 1 fan 4 to work through the control console 3, the exhaust gas can be input into the installation cylinder 18 through the air port. When the exhaust gas enters the installation cylinder 18 and the air pressure reaches the set value, the air in the installation cylinder 18 is discharged into the dust removal box 2 through the cloth bag 20, and the clean gas after final filtration can be discharged through the exhaust pipe 6. In this process, the drive component and the No. 1 fan 4 are controlled to switch intermittently through the installation platform, and the impurity removal component and the drive component are controlled to work synchronously. The control console 3 controls the stepping motor 13 to reciprocate and rotate, thereby controlling the synchronous rotation of the driving roller 14, and then driving the driving arm 15 to swing continuously. Under the action of the push arm 16, the connecting head 26 and The piston rod 27 reciprocates relative to the hollow tube 19, thereby inputting the outside air into the guide ring 24 and the impurity removal ring 23 along the hose 29. Since the airflows output by the No. 1 nozzle 33 and the No. 2 nozzle 35 are in a vertical state, the airflow ejected by the No. 1 nozzle 33 can enter the inside along the outside of the cloth bag 20, thereby flushing out the impurities attached to the inside of the cloth bag 20, and when the No. 2 nozzle 35 outputs the airflow, the detached impurities can be blown to the position of the air outlet and received by the impurity removal component. While the driving component controls the operation of the exhaust structure, it can control the movable arm 28, the guide ring 24 and the impurity removal ring 23 to reciprocate in the vertical direction, thereby realizing the cleaning of impurities on the inner wall of the cloth bag 20 at different positions. When the No. 1 fan 4 is working to input the exhaust gas into the air inlet barrel 5, the exhaust gas in the air inlet barrel 5 can enter the mounting tube 18 along the air port and the air inlet channel 11. When the No. 1 nozzle 33 and the No. 2 nozzle 35 respectively guide the airflow to the outer wall and the inner wall of the cloth bag 20, the impurities on the inner wall of the cloth bag 20 can fall into the impurity removal channel 12 under the action of gravity and the traction of the airflow, and when the control console 3 controls the No. 2 fan 7 to be powered on and rotated, the airflow can be input into the connecting box 10. The airflow through the connecting box 10 can drive the impurities in the impurity removal channel 12 to move and finally discharge them into the impurity box 8.
