Description

Technical Field

[0001] This application relates to the field of environmental protection, specifically to a dust collector filter bag that can be automatically cleaned by a program. Background Technology

[0002] Dust collector filter bags primarily rely on the filter bag for dust removal and are mainly used in larger industrial equipment, such as in the chemical industry. Because the emitted flue gas contains a large amount of dust, dust collector filter bags are essential for dust removal. Dust collector filter bags can be divided into internal filters and external filters. In internal filters, the dust-laden airflow enters the filter bag through the top opening and passes through the filter bag to become clean air. In external filters, the dust-laden gas enters the filter bag from the outside and exits through the top opening to form clean air. However, regardless of whether it is an internal or external filter, the essence is to rely on the filtration function of the filter bag to achieve the dust removal effect. Therefore, after a period of use, the filter bags must be cleaned. Otherwise, the filter pores will become clogged, leading to a decrease in dust removal efficiency. Furthermore, under the same ventilation volume, due to the reduced dust removal and ventilation effect of the filter bag, the filter bag will bear a greater thrust generated by the airflow, making it more prone to damage. Most existing dust removal methods use pulse-jet cleaning, but this method, which uses airflow for cleaning, sometimes has insufficient cleaning effect and uneven cleaning effect on different areas of the filter bag. Summary of the Invention

[0003] Purpose of the invention: In order to achieve a more direct dust removal method, this application discloses a dust removal filter bag that can be automatically cleaned by a program.

[0004] Technical Solution: A dust collector filter bag with automatic dust removal capability includes a base plate unit, a cage frame unit fixedly connected to the base plate unit, a filter bag unit installed at the cage frame unit, and a drive unit. The cage frame unit includes an upper circular ring portion, a lower circular ring portion, and multiple supporting vertical rods connected between the upper and lower circular ring portions. The base plate unit includes a circular base plate, a circular base plate, and multiple radial connecting plates connected between the circular base plate and the circular base plate. The radial connecting plates have strip-shaped grooves extending along the length direction of the radial connecting plates, and the strip-shaped grooves penetrate the upper and lower surfaces of the radial connecting plates. The dust collector filter bag also has multiple dust removal units, the number of which is equal to the number of radial connecting plates and they correspond one-to-one. Each dust removal unit includes a filter bag unit installed on the strip-shaped groove. The system includes a slide base, a tapping unit located below and fixedly connected to the slide base to tap the inner side of the filter bag unit, a tension spring connecting the slide base and the end of the strip-shaped slide near the annular base plate, a first fixed pulley mounted on the circular base plate, a second fixed pulley mounted on the annular base plate, and a pull rope connected to the slide base and passing through the corresponding first and second fixed pulleys. The annular base plate is equipped with a rotatable outer rotating ring and a rotatable inner rotating ring. Multiple dust removal units are divided into multiple first dust removal units and multiple second dust removal units. The pull rope of the first dust removal unit is connected to the outer rotating ring, and the pull rope of the second dust removal unit is connected to the inner rotating ring. The driving unit is used to drive the inner and outer rotating rings to rotate.

[0005] Furthermore, the upper annular portion is fixedly connected to the annular substrate.

[0006] Furthermore, the top ends of the first and second fixed pulleys have limiting circular plates.

[0007] Furthermore, the number of the first dust removal units is equal to the number of the second dust removal units, and the two are distributed alternately.

[0008] Furthermore, the number of the supporting vertical rods is greater than or equal to four.

[0009] Furthermore, multiple supporting vertical rods are distributed in a ring with equal spacing.

[0010] Furthermore, the outer rotating ring has multiple first anchor point units, the number of which is equal to the number of first dust removal units and they correspond one-to-one. The pull rope of each first dust removal unit is connected to one of the first anchor point units. The inner rotating ring has multiple second anchor point units, the number of which is equal to the number of second dust removal units and they correspond one-to-one. The pull rope of each second dust removal unit is connected to one of the second anchor point units.

[0011] Furthermore, the first anchor point unit is annular and fixedly connected to the outer rotating ring, and the second anchor point unit is annular and fixedly connected to the inner rotating ring.

[0012] Furthermore, the first anchor point unit protrudes from the inner circumferential surface of the outer rotating ring, and the second anchor point unit protrudes from the outer circumferential surface of the inner rotating ring.

[0013] Furthermore, there are four radial connecting plates, arranged in a ring with equal spacing. There are two first cleaning units and two second cleaning units.

[0014] Furthermore, the length of the tension spring when it does not undergo elastic deformation is less than one-quarter of the length of the strip groove.

[0015] Furthermore, the inner rotating ring is surrounded by the outer rotating ring, the ring base plate has an outer annular groove and an inner annular groove, the outer rotating ring has a plurality of outer sliders that cooperate with the outer annular groove, and the inner rotating ring has a plurality of inner sliders that cooperate with the inner annular groove.

[0016] Furthermore, the driving unit includes a mounting plate fixedly connected to the annular base plate, a drive motor mounted on the mounting plate, a drive gear driven by the drive motor, a driven gear mounted on the mounting plate and meshing with the drive gear, a rotating shaft connecting the driven gear and the mounting plate, and a lever fixed to the rotating shaft and rotating synchronously with the driven gear; a first protrusion is fixed at the outer rotating ring, and a second protrusion is fixed at the inner rotating ring; the lever can abut against the first protrusion to drive the outer rotating ring to rotate, and the lever can abut against the second protrusion to drive the inner rotating ring to rotate.

[0017] Furthermore, a fixing block is fixed at the annular base plate, and an elastic block is inherently present at the fixing block. An outer limiting block capable of abutting against the elastic block is fixed at the outer rotating annular ring, and an inner limiting block capable of abutting against the elastic block is fixed at the inner rotating annular ring.

[0018] This limits the positions of the outer and inner rotating rings, ensuring that the first and second protrusions are always in a state where they can be driven by the lever.

[0019] Furthermore, the end of the lever away from the pivot is arc-shaped.

[0020] Furthermore, both the first protrusion and the second protrusion are cylindrical, with a first circular baffle fixed to the top of the first protrusion and a second circular baffle fixed to the top of the second protrusion.

[0021] Furthermore, the lever can be in a first state and a second state. In the first state, the lever simultaneously abuts against the first protrusion and the second protrusion, so that all the tension springs are stretched. In the second state, the lever abuts against the first protrusion but not against the second protrusion, so that all the tension springs of the first dust removal unit are stretched.

[0022] Furthermore, the striking unit includes a first vertical plate connected to the slide, a horizontal plate connected to the first vertical plate, and a second vertical plate connected to the horizontal plate.

[0023] Furthermore, the elastic block is a rubber block or a sponge block.

[0024] Furthermore, the outer limiting block is fixed at the inner circumferential surface of the outer rotating ring; the inner limiting block is fixed at the outer circumferential surface of the inner rotating ring.

[0025] Furthermore, when both the inner and outer limit blocks abut against the elastic block, all the tension springs are in a state of no elastic deformation.

[0026] Furthermore, the outer circumferential surface of the upper ring portion has an annular groove.

[0027] Furthermore, the filter bag unit includes a bag body and a support ring located at the top of the bag body.

[0028] Furthermore, the bag body has a locking ring that fixes the bag body and the upper circular ring to each other. The locking ring is located below the support ring and is embedded in the circular groove.

[0029] Beneficial effects: Compared with traditional filter bag cleaning methods, the filter bag of this application adopts a more direct tapping cleaning method. It can tap the inside of the filter bag from different directions, thus achieving tapping cleaning. This cleaning method is more direct and can achieve simultaneous tapping cleaning from all directions, as well as sequential tapping cleaning from different directions, resulting in better cleaning performance. Furthermore, since the driving method is a motor drive, the cleaning operation can be controlled more precisely and automatically using program control. Attached Figure Description

[0041] As shown in the figure, this application discloses a dust collector filter bag, which is a single dust collector filter bag. In specific applications, the dust collector filter bag of this application is installed at the corresponding mounting hole position on the mounting plate to form a dust collector filter bag array, thereby achieving a larger dust removal efficiency. The filter bag adopts an external filtration method. After a period of use, a large amount of dust will adhere to the outside of the filter bag, so a dust cleaning operation is required. The dust cleaning method of this application adopts the method shown in the figure, in which the tapping unit directly taps the inside of the filter bag unit. When the inner rotating ring and the outer rotating ring rotate, the pull rope is pulled along the first and second fixed pulleys, thereby moving the slide away from the inside of the filter bag unit, and the tension spring is stretched. Specifically, as shown in the figure, the dust collector filter bag is originally in Figure 1 In the state shown, both the outer and inner rotating rings are not driven, and all the tension springs are not stretched. However, by driving the motor, the lever can abut against the first and second protrusions, thereby driving the outer and inner rotating rings to rotate, thus stretching all the tension springs. Figure 3 In the indicated state, you can then choose to quickly rotate the lever counterclockwise, simultaneously releasing the first and second protrusions. This causes all the tension springs to quickly reset, and all the tapping units tap the inside of the filter bag unit almost simultaneously (with a very short time difference), achieving dust removal. Alternatively, you can choose to continue rotating the lever clockwise. After rotating to a certain angle, the second protrusion will first pass over the free end of the lever (at this time, the first protrusion is still abutted by the lever), thus enabling the tapping units of the second dust removal unit to perform tapping dust removal. After dust removal is complete, the lever can continue rotating clockwise to a certain angle, allowing the first protrusion to also pass over the free end of the lever, thus enabling the tapping units of the first dust removal unit to perform dust removal. After dust removal is complete, the lever can continue rotating clockwise, rotating to... Figure 1 The state shown prepares the system for the next dust cleaning cycle. Each dust cleaning operation can begin with several simultaneous dust cleaning operations involving all the tapping units (this mode cleans dust in all directions, resulting in high cleaning efficiency), followed by several separate dust cleaning operations involving the first and second dust cleaning units (this method provides better cleaning results for the direction being tapped), thus making the dust cleaning more thorough.
