DETAILED DESCRIPTION

[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0049] See also Figures 1 to 10In an embodiment of the present invention, a filter device for air intake pretreatment includes: a partition 4, an air supply hood 7 and an electrostatic adsorption device 28, a pump air assembly, a first drive assembly, a second drive assembly and a side plate 26.

[0050] The air intake pre-treatment filter device 1 is provided with an air inlet 101 and an air outlet 102;

[0051] The partition plate 4 is arranged in the air intake pre-treatment filter device 1, and a filter screen 5 is detachably mounted on the partition plate 4;

[0052] The air supply hood 7 and the electrostatic adsorption device 28 are respectively arranged on both sides of the filter 5, wherein the electrostatic adsorption device 28 is provided with multiple groups of electrode needles 2801 on the side facing the filter 5. The multiple groups of electrode needles 2801 can increase the effective adsorption area of ​​the electrostatic adsorption device 28, so that the electrostatic adsorption device 28 can adsorb more dust particles at a time, thereby avoiding the situation where the adsorption effect of the electrostatic adsorption device 28 decreases after dust particles accumulate to a certain extent on the electrostatic adsorption device 28 due to the effective adsorption capacity of the electrostatic adsorption device 28.

[0053] It is worth noting that the exhaust gas to be treated enters the air pretreatment filter device 1 from the air inlet 101 and is discharged from the air outlet 102. During this process, the exhaust gas to be treated can pass through the filter 5, so that the dust particles in the exhaust gas to be treated are filtered out, and the electrostatic adsorption device 28 is located on the side of the filter 5 close to the air inlet 101, and the air supply hood 7 is located on the side of the filter 5 facing the air outlet 102, and the air supply hood 7 is in a state of being in contact with the filter 5.

[0054] The air pump assembly is connected to the air delivery cover 7, and the air pump assembly includes two sets of air pump structures, and an abutment member 13 is elastically provided at one end of the air pump structure;

[0055] The pump air structure includes a pump cylinder body 8 fixedly connected to the air supply hood 7, two groups of one-way valves 9 are arranged on the pump cylinder body 8, and a sealing plug 10 is sealingly and slidably installed in the pump cylinder body 8, and the sealing plug 10 is connected to a connecting shaft 11 that passes through the pump cylinder body 8. It should be noted that the conduction directions of the above-mentioned two groups of one-way valves 9 are opposite, and the conduction direction of one group of one-way valves 9 is from the outside to the inside of the pump cylinder body 8, and the conduction direction of the other group of one-way valves 9 is from the inside of the pump cylinder body 8 to the outside (air supply hood 7).

[0056] The connecting shaft 11 is sleeved with a first spring 12, one end of the first spring 12 is connected to the sealing plug 10, and the other end is connected to the inner wall of the pump cylinder body 8;

[0057] See also Figure 6 and Fig.11, one end of the connecting shaft 11 away from the sealing plug 10 is slidably connected to the abutment 13, the abutment 13 and the connecting shaft 11 are connected via a second spring 14, and a stopper 1301 is provided on the abutment 13. In the initial state, the stopper 1301 is in a state of abutting the connecting shaft 11, and at this time the second spring 14 is in a stretched state, so that in the initial state, the abutment 13 can have a good stability, ensuring that it can cooperate with the first driving assembly to realize the action;

[0058] A first inclined surface 1302 is disposed at one end of the abutment member 13 away from the second spring 14 .

[0059] When in use, when the first driving component is actuated, it can abut against one of the abutment members 13 and drive the connecting shaft 11 connected thereto to actuate. At this time, the connecting shaft 11 can drive the sealing plug 10 to move away from the one-way valve 9 to suck external air into the pump cylinder 8 while compressing the second spring 14. When the abutment 13 moves to the end of the stroke, it will separate from the first driving component. At this time, the second spring 14 can release elastic potential energy and compress the air in the pump cylinder 8 into the air supply hood 7, thereby increasing the pressure in the air supply hood 7 instantly. This can enable the air in the air supply hood 7 to move along the direction of the filter screen 5, and the dust particles adhering to the filter screen 5 can be separated from the filter screen 5 and adsorbed by the electrostatic adsorption device 28, effectively preventing the dust particles from accumulating on the filter screen 5, resulting in a decrease in the filtering effect of the filter screen 5, thereby improving the filtering effect and enabling the waste gas to be treated to pass through the filter screen 5 faster.

[0060] Furthermore, since two sets of air pumping structures are provided, during the reciprocating action of the first driving component, the two sets of air pumping structures can be driven alternately to operate, so that under the trend of the two sets of air pumping structures, the air supply hood 7 can continuously deliver compressed air to the filter 5, and ensure that when the air supply hood 7 and the electrostatic adsorption device 28 move along the length direction of the filter 5, all the dust adhering to one side of the filter 5 can be blown away and separated from the filter 5, and adsorbed by the electrostatic adsorption device 28, so that the dust particles adhering to one side of the filter 5 can be evenly processed.

[0061] Through the above-mentioned arrangement, when the first driving component is actuated, the sealing plug 10 can be driven to act, and when the abutment member 13 is separated from the first driving component, the second spring 14 releases elastic potential energy to pressurize the air supply hood 7, and the compressed air passes through the filter screen 5 in the reverse direction, so that the dust particles adhering to the filter screen 5 are separated from the filter screen 5 and adsorbed by the electrostatic adsorption device 28, so as to achieve the effect of removing the dust particles adhering to the filter screen 5, avoid the filter screen 5 from being blocked by dust particles due to long-term filtering, improve the filtering effect of the filter screen 5, and increase the speed of the exhaust gas to be treated passing through the filter screen 5.

[0062] See also Figure 3 , Figure 5 , Figure 6 , Figure 7 and Fig.12 The first driving assembly is connected to the air supply hood 7, and the first driving assembly cooperates with the abutment member 13 to alternately drive the two groups of the air pumping structures to operate;

[0063] The first driving assembly includes a bracket 18 fixedly connected to the air supply hood 7, an electric telescopic rod 17 is fixedly mounted on the bracket 18, a sliding connection 1701 is connected to the action end of the electric telescopic rod 17, and the sliding connection 1701 is slidably connected to a guide groove 1801 provided on the bracket 18;

[0064] The sliding connection member 1701 is connected to a transverse rod 19, and abutment wheels 20 are rotatably mounted on both ends of the transverse rod 19;

[0065] The first driving assembly further comprises a trigger structure connected to the abutment member 13, wherein the trigger structure can separate the abutment member 13 from the abutment wheel 20 after the abutment wheel 20 drives the abutment member 13 to move to a predetermined position;

[0066] The trigger structure includes a first protruding shaft 15 rotatably mounted on the abutment member 13 and a trigger member 16 connected to the air supply cover 7. The first protruding shaft 15 cooperates with the trigger member 16 to enable the abutment member 13 to move away from the abutment wheel 20.

[0067] The trigger member 16 is provided with a second inclined surface 1601 on one side facing the first protruding shaft 15 . When the first protruding shaft 15 abuts against the second inclined surface 1601 , the abutting member 13 can slide relative to the connecting shaft 11 and separate from the abutting wheel 20 .

[0068] When in use, the electric telescopic rod 17 drives the transverse rod 19 to move along the length direction of the guide groove 1801, and makes one of the abutting wheels 20 abut against one of the abutting members 13, and drives the abutting members 13 to move, so that the pumping structure connected to the abutting members 13 can draw in air, and with the movement of the abutting members 13, the first convex shaft 15 on the abutting member 13 will abut against the second inclined surface 1601 on the trigger member 16, and make the abutting member 13 move away from the abutting wheel 20 along its length direction, and after the two are separated (the abutting member 13 moves to the other side of the abutting wheel 20), the first spring 12 can release the elastic potential energy, and press the air in the pumping structure into Inside the air supply hood 7, at the same time, the abutment wheel 20 at the other end of the transverse rod 19 can abut against the first inclined surface 1302 on the other group of abutment members 13, and make the abutment members 13 move along their own length until the abutment wheel 20 moves to the other side of the abutment members 13, and then the transverse rod 19 can stop moving, and then move in the opposite direction, to repeat the above process, so as to achieve the purpose of alternately driving the two groups of pumping air structures, and have the effect of continuously delivering compressed air into the air supply hood 7, to ensure that when the air supply hood 7 moves along the length direction of the filter screen 5, the air supply hood 7 can always pump reverse air toward the filter screen 5, so as to separate the dust particles adhering to the filter screen 5 from the filter screen 5.

[0069] Through the above arrangement, when the electric telescopic rod 17 is in motion, the two sets of pumping air structures can be driven alternately to operate so as to continuously deliver compressed air to the air supply hood 7, thereby ensuring that when the air supply hood 7 moves along the length direction of the filter screen 5, the air supply hood 7 can always pump reverse air toward the filter screen 5, so that the dust particles adhering to the filter screen 5 are separated from the filter screen 5, and the dust particles adhering to one side of the filter screen 5 can be evenly processed.

[0070] See also Figure 3-4 , Figure 8 to Figure 10 The second driving assembly is connected to the electrostatic adsorption device 28, and a second convex shaft 25 is formed on the second driving assembly;

[0071] The second driving assembly includes a first linear driving module 6 and a second linear driving module 21 which are arranged on both sides of the filter 5. The first linear driving module 6 is connected to the air supply hood 7. It is worth noting that the first linear driving module 6 and the second linear driving module 21 can act synchronously when they are in motion, so that when the two drive the air supply hood 7 and the electrostatic adsorption device 28 to act, the air supply hood 7 can maintain the same height as the electrostatic adsorption device 28 in real time, and when the air supply hood 7 pumps reverse air, the electrostatic adsorption device 28 can adsorb the dust particles blown away by the reverse air.

[0072] The second linear drive module 21 is connected to the electrostatic adsorption device 28 via an elastic structure, the elastic structure includes a connecting plate 23 fixedly connected to the electrostatic adsorption device 28, the connecting plate 23 is provided with a slide groove 2301 along its length direction, a follower block 22 fixedly connected to the second linear drive module 21 is slidably installed in the slide groove 2301, and the follower block 22 is connected to the inner wall of the slide groove 2301 via a third spring 24;

[0073] The second convex shaft 25 is rotatably connected to the connecting plate 23;

[0074] The side plate 26 is connected to the inner wall of the air intake pre-treatment filter device 1, and the guide groove provided on the side plate 26 cooperates with the second convex shaft 25, so that when the electrostatic adsorption device 28 moves to the end of the stroke, the electrostatic adsorption device 28 performs a vibration action;

[0075] The guide groove includes a first vertical groove 2601 provided on the side plate 26, a second vertical groove 2602 is provided at one end of the first vertical groove 2601, a horizontal groove 2603 is provided at one end of the second vertical groove 2602 away from the first vertical groove 2601, a third vertical groove 2604 is connected to one end of the horizontal groove 2603 away from the second vertical groove 2602, and the third vertical groove 2604 is connected to the second vertical groove 2602 via an inclined groove 2605;

[0076] A deflection member 27 is rotatably mounted at the connection between the inclined slot 2605 and the second vertical slot 2602 . A torsion spring is disposed on the rotation axis of the deflection member 27 so that the end of the deflection member 27 is in contact with the inclined slot 2605 .

[0077] In the initial state, the second convex shaft 25 is at one end of the first vertical slot 2601 away from the second vertical slot 2602. At this time, the third spring 24 is in a stretched state. As the air supply hood 7 and the electrostatic adsorption device 28 move, the dust particles blown away by the reverse airflow will be adsorbed on the electrostatic adsorption device 28. At the same time, when the air supply hood 7 and the electrostatic adsorption device 28 move, the second convex shaft 25 will also move along the first vertical slot 2601. After the second convex shaft 25 moves to the end of the first vertical slot 2601, the second convex shaft 25 can enter the second vertical slot 2602 under the guidance of the deflection member 27, and when the second convex shaft 25 moves to the first vertical slot 2601, the second convex shaft 25 can enter the second vertical slot 2602 under the guidance of the deflection member 27. After reaching the end of the second vertical groove 2602, the third spring 24 can release elastic potential energy and drive the second cam 25 to move along the horizontal groove 2603. When the second cam 25 abuts against the third vertical groove 2604, the electrostatic adsorption device 28 can stop moving instantly and produce a vibration effect. At this time, the dust particles adhering to the electrostatic adsorption device 28 can be separated from the electrostatic adsorption device 28 under the action of the vibration force, so that when the electrostatic adsorption device 28 moves upward, it can maintain a good adsorption effect, thereby preventing the dust particles from adhering to the filter 5 again after the air supply hood pumps reverse air to separate them from the filter 5 due to a decrease in the adsorption effect.

[0078] When the electrostatic adsorption device 28 and the air supply hood 7 move upward, the second cam shaft 25 will move along the third vertical groove 2604 and the inclined groove 2605, and when it abuts against the deflection member 27, it will drive the deflection member 27 to deflect. At this time, the torsion spring can store potential energy, and when the second cam shaft 25 moves upward along the first vertical groove 2601 and separates from the deflection member 27, the deflection member 27 can be reset, thereby realizing periodic guidance of the second cam shaft 25 and ensuring that the electrostatic adsorption device 28 can perform a vibration action when it moves to the lower end of the stroke.

[0079] Through the above-mentioned arrangement, when the air supply hood 7 and the electrostatic adsorption device 28 move to the lower end of the stroke, the third spring 24, the second cam 25 and the horizontal groove 2603 can cooperate to drive the electrostatic adsorption device 28 to perform a movement process of first accelerating and then stopping instantly, and generate vibration. The vibration force is used to shake off the dust adhering to the electrostatic adsorption device 28, so that the electrostatic adsorption device 28 can restore its adsorption performance, thereby preventing the dust particles from adhering to the filter 5 again after the air supply hood pumps reverse air to separate them from the filter 5 due to a decrease in the adsorption effect.

[0080] It should be supplemented that, when the electrostatic adsorption device 28 moves to the lower end of the stroke, the electrostatic adsorption device 28 can be automatically powered off.

[0081] As an embodiment of the present invention, a paint mist catalytic combustion furnace is also proposed, which includes the above-mentioned filter device for air intake pretreatment, and also includes a combustion device 2 and an exhaust device 3.
