[0002] A large amount of dust will be discharged into the air on large equipment. Generally, a pulse bag filter is used to filter the dust and then discharge the gas discharged from the equipment into the air. The pulse bag filter has the advantages of high dust removal efficiency and strong adaptability, but also has the disadvantages of high equipment cost, high maintenance cost and large floor area. The pulse dust collector generally needs to be installed above the large equipment. Due to the high viscosity of the dust, it is easy to cause the filter cloth to cake, resulting in an increase in the resistance of the dust collector and affecting the dust removal effect. The filter bag needs to be cleaned and replaced frequently. After the above situation occurs, the filter bag needs to be removed from the dust collector and the surface of the filter cloth is rinsed with clean water. After rinsing and drying, it can be used continuously. The maintenance of the dust collector is too frequent. Therefore, for the dust collector used above large equipment, we need a dust collector with a small volume and easy to maintain. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The following will describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention:

[0020] As shown in the figure, a micro pulse dust collector includes a connected filter cylinder body 1 and a gas bag assembly 2. The gas bag assembly 2 includes a gas bag 21. An inflation port 23, a mini ball valve 26 and a gas guide pipe 24 are provided on the gas bag 21. The inflation port 23 is used to inflate the gas bag 21 when the gas in the gas bag 21 is insufficient. The mini ball valve 26 is used to relieve the pressure of the gas bag 21 when the pressure in the gas bag 21 is too high. A pulse solenoid valve 22 is provided on the gas guide pipe 24. The pulse solenoid valve 22 is used to generate a pulse air flow. One end of the gas guide pipe 24 is connected to the gas bag 21 and the other end is connected to the filter cylinder body 1. When the pulse solenoid valve 22 is opened, the high-pressure gas in the gas bag 21 enters the filter cylinder body 1 through the gas guide pipe 24. When the pulse solenoid valve 22 is closed, the gas bag 21 is not connected to the filter cylinder body 1. The filter cylinder body 1 includes a lower cylinder body 11 and an upper cylinder body 12. The lower cylinder body 11 and the upper cylinder body 12 are detachably connected. The upper part of the lower cylinder body 11 is connected to a lower flange 16, and the lower part of the upper cylinder body 12 is connected to an upper flange 15. The lower flange 16 and the upper flange 15 are detachably connected by bolts, and the lower flange 16 and the upper flange 15 are sealed by a sealing ring. An air inlet 13 is provided at the bottom of the lower cylinder body 11. The air containing dust enters the filter cylinder body 1 through the air inlet 13. An air outlet 14 is provided at the top of the upper cylinder body 12. The filtered air is discharged from the filter cylinder body 1 through the air outlet 14. A filter element 5 is detachably connected inside the filter cylinder body 1. The filter element 5 is used to filter the dust in the air. The material of the filter element 5 is PTFE. The filter element 5 includes a filter element inner layer 54, a filter element outer layer 53 and an upper end nut 52. A spray air pipe 51 is provided inside the filter element 5. The spray air pipe 51 is communicated with the gas guide pipe 24. The spray air pipe 51 sprays the high-pressure gas onto the filter element 5, and blows the dust attached to the filter element 5 into the dust collection hopper 18. The dust collection hopper 18 is in the shape of an inverted frustum, and is provided at the lower part of the lower cylinder body 11 and above the air inlet 13. The height of the filter element inner layer 54 is greater than the height of the filter element outer layer 53. In this way, the filter element inner layer 54 can be higher than the filter element outer layer 53 by a section. The part where the filter element inner layer 54 is higher than the filter element outer layer 53 can be screwed tightly with the upper end nut 52. A connecting plate 17 is clamped between the upper end nut 52 and the filter element outer layer 53, forming a state where the filter element 5 is suspended inside the filter cylinder body 1. The connecting plate 17 is annular. The inner circle of the connecting plate 17 is sleeved on the outer circle of the filter element inner layer 54 and the inner circle radius of the connecting plate 17 is smaller than the outer circle radius of the filter element outer layer 53, ensuring that the connecting plate 17 can be clamped and fixed after the upper end nut 52 is screwed tightly close to the filter element outer layer 53. The outer circle radius of the connecting plate 17 is the same as the radius of the upper flange 15 and the connecting plate 17 is arranged between the lower flange 16 and the upper flange 15. Sealing gaskets are provided between the connecting plate 17 and the lower flange 16 and the upper flange 15. When the lower flange 16 and the upper flange 15 are fixed, the connecting plate 17 is fixed together.

[0021] The lower cylinder body 11 is provided with a mounting seat 3 in the direction of the air bag 21. The air bag 21 is fixed on the mounting seat 3 through a mounting plate 25. The height error between the workpiece can be adjusted by a gasket 4 between the mounting plate 25 and the mounting seat 3. The internal communication between the filter cylinder body 1 and the air bag assembly 2 is realized through an air guide pipe 24, and the external fixed connection is realized through the mounting seat 3.

[0022] During use, first connect the filter element 5 with the connecting plate 17. The specific process is that the upper part of the inner layer 54 of the filter element passes through the inner circle of the connecting plate 17, the upper end of the outer layer 53 of the filter element abuts against the lower end of the connecting plate 17, and the upper nut is sleeved on the upper end of the inner layer 54 of the filter element and tightened to realize that the filter element 5 is suspended in the center of the connecting plate 17. Then place the filter element 5 in the lower cylinder body 11. At this time, the outer periphery of the connecting plate 17 is placed on the lower flange 16. Connect the upper cylinder body 12 with the air guide pipe 24, and the air guide pipe 24 is connected with the air spraying pipe. The upper cylinder body 12 is placed on the connecting plate 17 along with the upper flange 15. A sealing gasket is placed between the upper cylinder body 12, the connecting plate 17 and the lower cylinder body 11 to complete the assembly of the filter cylinder body 1. Fix the mounting seat 3 with the lower cylinder body 11, and fix the air bag 21 on the mounting seat 3 through the mounting plate 25. When the filter element 5 can work normally, the pulse solenoid valve 22 is closed, and there is no communication between the air bag 21 and the filter cylinder body 1. Air enters from the air inlet 13, is filtered by the filter element 5 and discharged through the air outlet 14. After the filter element 5 works for a period of time, the filter holes will be blocked by dust. There is no need to remove and clean the filter element. Just start the pulse solenoid valve 22, and the air bag 21 conveys high-pressure gas to the filter element 5 to blow and remove dust from the filter element 5. After that, the filter element 5 can resume normal filtering work. If the filter element 5 needs to be replaced, just remove the old one and install a new one.

[0023] The present utility model provides a micro pulse dust collector, which efficiently removes the dust on the filter element 5 by means of pulse air flow, replacing the original bag dust collector. The noise generated by the pulse jetting method is small, reducing the impact on the surrounding environment; there is no need to frequently clean and replace the cloth bag. Compared with the bag dust collector, it has a smaller volume and is more convenient to maintain.

[0024] The above embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
