Description

Technical Field

[0001] This invention relates to the field of vacuum insulation panel production technology, specifically to a waste gas treatment device used in the production of vacuum insulation panels. Background Technology

[0002] Vacuum insulation panels are currently the best-performing new type of high-efficiency thermal insulation material. The core of this material is a combination of a high vacuum environment, a low thermal conductivity core material, and a high-barrier encapsulation film, which achieves a thermal insulation effect far superior to traditional insulation materials (polyurethane, rock wool, polystyrene board, etc.). It is widely used in cold chain, construction, home appliances, new energy and other fields with high requirements for thermal insulation and space.

[0003] Vacuum insulation panels generate certain waste gas and particulate dust during production. Currently, most cleaning methods involve filtering with filter cartridges and membranes. However, after prolonged filtration, the accumulated dust particles can easily cause blockages, affecting the filtration effect and efficiency. Furthermore, the filter cartridge is usually located in the same space as the ventilation pipe. When workers clean the dust particles, it can easily cause secondary dust generation and dust particle leakage, posing certain inconveniences and potential hazards. Summary of the Invention

Detailed Implementation

[0024] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0025] like Figure 1-7As shown, a waste gas treatment device for the production of vacuum insulation panels includes a treatment section 1. Waste gas enters the treatment section 1 and is filtered within it before being discharged. A filter section 2 is provided within the treatment section 1 to filter the waste gas and separate solid particles, thus preventing floating particles from being emitted. The filter section 2 includes a filter element 21 disposed within the treatment section 1. A fixing frame 22 is provided within the filter element 21. Several equally spaced slots 23 are formed on the surface of the fixing frame 22. Waste gas enters the interior of the fixing frame 22 through the filter element 21 and the slots 23. Solid dust particles are adsorbed onto the surface of the filter element 21, facilitating the filtration of the waste gas. A fixing plate 25 is fixedly connected to the bottom end of the filter element 21 for mounting the bottom of the treatment section 1. The filter element 21 is sealed at one end. A soft brush 9 is installed inside the processing unit 1, located directly below the filter element 21. The filter element 21 can be raised, lowered, and rotated. When the filter element 21 descends to the soft brush 9, rotating the soft brush 9 cleans the surface of the filter element 21, allowing it to be reused. This prevents excessive dust from clogging the filter element 21 and affecting its filtration effect and efficiency. A sealing box 4 is slidably connected inside the processing unit 1, with the soft brush 9 located inside. The bottom of the sealing box 4 is open, allowing it to be in both open and closed states. As the filter element 21 moves from top to bottom, the sealing box 4 switches between these two states. When the sealing box 4 is open, the filter element 21 enters it, and then the sealing box 4 closes, effectively preventing dust leakage when cleaning the dust on the filter element 21.

[0026] like Figure 1-4 As shown, the processing unit 1 includes a processing box 11, with a partition 12 fixedly connected inside the processing box 11. The top of the fixing frame 22 is fixedly connected to the bottom surface of the partition 12. The partition 12 can divide the processing unit 1 into an air inlet chamber and an air outlet chamber. An air inlet pipe 13 is fixedly connected to the surface of the processing box 11 and is connected to the air inlet chamber. An air outlet pipe 14 is fixedly connected to the surface of the processing box 11 and is connected to the air outlet chamber. A one-way valve is installed on the air outlet pipe 14 so that gas can only be discharged from the air outlet chamber and cannot enter. Inside the exhaust chamber, a through hole 15 is provided in the partition 12, and the through hole 15 is located inside the filter section 2. The inlet chamber and the outlet chamber are connected through the through hole 15. The exhaust gas enters the inlet chamber through the inlet pipe 13, and then the external negative pressure device is connected to the outlet chamber. At this time, the exhaust gas can enter the outlet chamber through the filter element 21, the through groove 23 and the through hole 15 under the action of pressure. The dust will be filtered on the surface of the filter element 21. Finally, the exhaust gas is discharged from the outlet pipe 14, thus making it convenient to filter the particulate dust in the exhaust gas.

[0027] like Figure 2-4As shown, the filter element 21 is provided with several baffles 24 that are adapted to the through groove 23. The baffles 24 can rotate to block the through groove 23, so that the exhaust gas cannot enter the fixed frame 22. At this time, the filter element 21 can be raised and lowered for cleaning.

[0028] like Figure 2-4 As shown, the processing box 11 is equipped with a drive unit 3, which can drive the baffle 24 to rotate and the filter element 21 to rotate. When the filter element 21 is filtering, it rotates so that the dust is evenly distributed on the surface of the filter element 21, preventing the dust from accumulating locally, affecting the service life of the filter element 21, and reducing the cleaning efficiency of the filter element 21. The drive unit 3 includes a servo motor 31 fixedly connected to the processing box 11, and the output end of the servo motor 31 extends into the processing box 11. The output end of the servo motor 31 is fixedly connected to a connecting shaft 32, and the bottom end of the connecting shaft 32 passes through the through hole 15 and extends to the bottom of the fixing plate 25. A fixing ring 33 is rotatably connected to the surface of the connecting shaft 32 through a one-way bearing, and the fixing ring 33 is fixedly connected to the baffle 24. When the connecting shaft 32 rotates forward, it can drive the fixing ring 33 to rotate. A first sliding groove 34 is opened on the surface of the connecting shaft 32, and a sliding rod 35 is slidably connected in the first sliding groove 34. The sliding rod 35 is connected to the fixing plate 25 through a one-way bearing 36. When the connecting shaft 32 rotates in reverse, it can drive the fixing plate 25 to rotate. Then, the rotation of the fixing plate 25 can drive the filter element 21 to rotate, thereby facilitating the rotation of the baffle 24 or the fixing plate 25.

[0029] like Figure 3 As shown, the sealing box 4 is provided with a connecting part 5, which is used to drive the sealing box 4 to switch between the open and closed states, so that the filter element 21 can easily enter the sealing box 4. When the filter element 21 enters the sealing box 4, it can drive the filter element 21 to rotate, so that the soft brush 9 can more easily clean the surface of the filter element 21. The connecting part 5 includes a reciprocating screw 51 rotatably connected to the bottom end of the connecting shaft 32. A one-way bearing is threaded onto the surface of the reciprocating screw 51, and the outer ring of the one-way bearing is fixedly connected to the lifting plate 52. The forward rotation of the reciprocating screw 51 can drive the lifting plate 52 to move through the one-way bearing. Two connecting rods 53 are hinged to both ends of the lifting plate 52, and the ends of the two connecting rods 53 away from the lifting plate 52 are hinged to the inner wall of the sealing box 4. A second sliding rod 35 is provided on the surface of the reciprocating screw 51. The second slide groove 54 overlaps with the first slide groove 34. A space 56 is provided within the lifting plate 52. A first pulley 57 is fitted onto the surface of the reciprocating screw 51 and is rotatably connected within the space 56. A limit slider 55 is slidably connected within the second slide groove 54 and is fixedly connected to the first pulley 57. A second pulley 58 is rotatably connected within the space 56, and the second pulley 58 is connected to the first pulley 57 via a transmission belt. The lifting plate 52... A servo motor 59 is fixedly connected to the bottom surface of the filter element 21, and the output end of the servo motor 59 extends into the space 56 and is fixedly connected to the second pulley 58. First, the servo motor 59 is started. The rotation of the output end of the servo motor 59 can drive the reciprocating screw 51 to rotate. Then, the forward rotation of the reciprocating screw 51 can drive the lifting plate 52 to move downward. Then, the movement of the lifting plate 52 can push the two sealing boxes 4 to move in opposite directions through the connecting rod 53. When the lifting plate 52 moves to the middle of the sealing box 4, the distance between the two sealing boxes 4 is just slightly larger than the maximum diameter of the filter element 21. At this time, the filter element 21 can fall into the sealing box 4. Then, the lifting plate 52 continues to move, and the two sealing boxes 4 will move closer to each other, thereby sealing the filter element 21 in the sealing box 4. Then, the reciprocating screw 51 is reversed. The reciprocating screw 51 can drive the fixed plate 25 to rotate, thereby enabling the filter element 21 to rotate. This makes it easier to treat the dust on the surface of the filter element 21 and effectively prevents dust leakage. It should be noted that the surface of the reciprocating lead screw 51 is covered with a sealing protective sleeve to prevent dust from damaging the reciprocating lead screw 51.

[0030] like Figure 4 and Figure 6 As shown, the lifting plate 52 is provided with a reset part 6. When the lifting plate 52 moves from bottom to top, it can push the filter element 21 to move upward and reset. At this time, the filter element 21 can be put back on the surface of the fixed frame 22 and continue to filter the exhaust gas, thus making it easy to drive the filter element 21 to reset. The reset part 6 includes an insertion rod 61 rotatably connected to the bottom surface of the fixed plate 25 via an annular groove and an annular slider. The insertion rod 61 can rotate around the axis of the fixed plate 25, and the bottom end of the insertion rod 61 extends into the interior of the sealing box 4. The lifting plate 52 has an insertion hole 62 adapted to the insertion rod 61, and a conical rubber block 63 is fixedly connected in the insertion hole 62. The insertion rod 61 can be inserted into the conical rubber block 63. When the lifting plate 52 moves downward, the insertion rod is stopped by the sealing box 4. 61 will not move up or down. When the lifting plate 52 moves to the middle of the sealing box 4, the filter element 21 enters the sealing box 4. At this time, the bottom end of the insertion rod 61 is located at the top of the conical rubber block 63. Then the lifting plate 52 moves upward, which can push the insertion rod 61 and the filter element 21 to move upward. When the filter element 21 moves to contact the bottom surface of the partition plate 12, the insertion rod 61 will be inserted into the conical rubber block 63. Thus, after cleaning, the lifting plate 52 can easily drive the filter element 21 to reset.

[0031] like Figure 1-4 As shown, a collection section 7 is provided below the processing box 11 to collect the dust cleaned from the surface of the filter element 21, so that workers can carry out centralized processing later. The collection unit 7 includes a collection box 71 fixedly connected to the bottom of the processing box 11. The collection box 71 is connected to the processing box 11 through a connecting port 73, and the connecting port 73 is located below the sealing box 4. A collection box 72 is slidably connected inside the collection box 71. The cleaned dust can fall into the collection box 72 through the connecting port 73. The staff can handle the dust particles by pulling out the collection box 72, thus making it convenient to carry out centralized processing.

[0032] Working principle: First, untreated exhaust gas is injected into the intake chamber. Then, the exhaust gas enters the outlet chamber through the filter section 2. The filter element 21 can filter particulate dust in the exhaust gas. The particulate dust can be adsorbed on the surface of the filter element 21. During processing, the filter element 21 can rotate, which can make the dust evenly distributed on the surface of the filter element 21 and prevent local dust accumulation. After processing, the sealing box 4 is switched to the open state through the drive section 3 and the connecting section 5, and the filter element 21 can enter the sealing box 4. Then the sealing box 4 is closed. At this time, the rotation of the filter element 21, together with the soft brush 9, can clean the dust particles on the surface of the filter element 21. This makes it easy to filter dust particles and clean the filter element 21, thus improving the service life of the filter element 21.
