[0003] When the high temperature resistant and high efficiency air filter is in use, it is driven by the fan of the air handling system or ventilation system where the filter is located to filter the outside air to the filter element and intercept the particulate matter in the air, thereby achieving the purpose of filtering the air.

[0004] Through long-term observation, although the existing air filter can intercept particulate matter in the air, the filter element will gradually accumulate dust during use and needs to be replaced. The filter element installation port of the existing air filter is usually consistent with the width of the filter element, which makes the installation process troublesome. Therefore, a high-temperature resistant and high-efficiency air filter is proposed to solve the above problems. Utility Model Content

[0025] Specific examples are given below.

[0026] like Figure 1-4As shown, a high temperature resistant high efficiency air filter comprises a filter body 1; a filter element 11 is installed in the middle of the filter body 1; two groups of spring rods 12 are fixedly connected to the top of the filter body 1; the output end of the spring rod 12 is fixedly connected to a first pressing plate 13, and the first pressing plate 13 is slidably arranged on the top of the filter body 1; two groups of second pressing plates 17 are fixedly connected to the middle of the first pressing plate 13; two groups of pull ropes 14 are fixedly connected to the end of the first pressing plate 13, and the pull ropes 14 are arranged to penetrate the middle of the filter body 1; a slider 15 is fixedly connected to the bottom of the pull rope 14, and the slider 15 is slidably arranged on the top of the filter body 1 The block 15 is slidably arranged on the outer wall of the filter body 1; a receiving groove 16 is provided in the middle of the slider 15; when working, the staff needs to install the filter body 1 at the vent position, so that when the ventilation device is working, the air will pass through the filter element 11 and perform filtering work. By providing a mounting hole larger than the thickness of the filter element 11 in the middle of the filter body 1, when the filter element 11 is installed inside the filter body 1, the staff can align the filter element 11 with the mounting position, and then place it. At this time, the heavy objects from the outside can be placed in the receiving groove 16 The slider 15 is internally pressed downward by the gravity, and the first pressing plate 13 is pulled toward the side wall of the filter element 11 by the pull rope 14, until the second pressing plate 17 contacts the middle of the filter element 11, and the filter element 11 is fixed by the extrusion force. When the filter element 11 needs to be taken out and replaced, the heavy object is separated from the storage groove 16, and the reaction generated by the spring rod 12 is used to reset it. This step cooperates with the first pressing plate 13 to reduce the staff's time in installing the filter element 11. When installing or removing, due to the narrow installation diameter of the filter element 11, the middle of the filter element 11 may be bent or even damaged during the installation process, and the accumulation of impurities is reduced when the filter element 11 is replaced and cleaned. At the same time, when facing a high temperature environment, the filter element 11 can be frequently replaced to improve the stability of the equipment in a high temperature environment, reduce the temperature rise caused by impurity accumulation, and increase the speed of the staff in installing the filter element 11. The spring rod 12 with elastic force can facilitate the overall reset of the first pressure plate 13, reducing the need for manual reset.

[0027] like Figure 1-3As shown, the top of the spring rod 12 is fixedly connected to a top piece 2; the end of the top piece 2 is fixedly connected to a shielding cloth 21, and the other end of the shielding cloth 21 is fixedly connected to the side wall of the first pressure plate 13; the middle of the output end of the spring rod 12 is fixedly connected to a support rod 22; the middle of the support rod 22 is rotatably connected to a rotating wheel 23, and the rotating wheel 23 is arranged at the bottom of the shielding cloth 21; when working, by arranging a first pressure plate 13 on the top of the spring rod 12, when the first pressure plate 13 as a whole moves toward the side wall of the filter element 11 under the action of a weight, it will pull the shielding cloth 21, so that the shielding cloth 21 can be straightened, so that the unfolded shielding cloth 21 blocks part of the installation hole position, and at the same time the shielding cloth 21 is in When storing, the rotating wheel 23 will directly contact the bottom of the shielding cloth 21, and at the same time support the middle part of the shielding cloth 21. This step cooperates with the shielding cloth 21 to reduce the first pressure plate 13 and gradually approach the middle part of the filter element 11, so that there is a partial gap between its end and the filter body 1. When the filter body 1 is used subsequently, foreign impurities fall into the gap, which makes it difficult to clean the inside of the filter body 1. The rotating wheel 23 can support the shielding cloth 21 in the placed state, reduce the middle part of the shielding cloth 21 and directly contact the output end of the spring rod 12, so that the spring rod 12 will be blocked and stuck during operation.

[0028] like Figure 4 As shown, a slide groove 3 is provided in the middle of the slider 15; a connecting rod 31 is slidably connected to the inner wall of the slide groove 3; a support plate 32 is fixedly connected to the middle of the connecting rod 31; during operation, a slidable connecting rod 31 is provided on the inner wall of the storage groove 16, so that the heavy object placed inside the storage groove 16 is relatively smooth, the staff can pull the connecting rod 31 upwards, and under the action of the support plate 32, the heavy object moves together, and then the heavy object can be taken out. This step is combined with the support plate 32 to reduce the heavy object to a spherical shape or a smooth top, which leads to the problem that the heavy object is difficult to take out later due to lack of a fulcrum.

[0029] like Figure 4 and 5As shown, the inner wall of the filter body 1 is fixed with multiple groups of elastic members 4; the ends of the elastic members 4 are fixed with gaskets 41, and the gaskets 41 are arranged in contact with the pull rope 14; during operation, by arranging multiple groups of elastic elastic members 4 in the middle of the filter body 1, after a heavy object is placed on the inner wall of the storage groove 16, the middle part of the pull rope 14 will contact the gasket 41 of soft material, and at the same time, the middle part of the elastic member 4 will be squeezed and deformed, and then it can slide in the middle part of the gasket 41. This step, together with the gasket 41 of soft material, can reduce the problem that the middle part of the pull rope 14 directly contacts the outer wall of the filter body 1 during use, causing greater wear on the middle part of the gasket 41, and the elastic gasket 41 can reset the working position of the pull rope 14, thereby improving the accuracy during subsequent use.

By providing a slidable connecting rod 31 on the inner wall of the storage groove 16, when the heavy object placed inside the storage groove 16 is relatively smooth, the staff can pull the connecting rod 31 upwards, and under the action of the supporting plate 32, the heavy object will move together, and then the heavy object can be taken out. By providing multiple groups of elastic elastic members 4 in the middle of the filter body 1, after the heavy object is placed on the inner wall of the storage groove 16, the middle part of the pull rope 14 will contact the gasket 41 of the soft material, and at the same time, it will squeeze the middle part of the elastic member 4 to deform. , and then slide in the middle of the gasket 41. By providing a scraper 5 on the side wall of the first pressing plate 13, when the first pressing plate 13 slides in the opposite direction, the dust accumulated on the top of the filter body 1 can be scraped off and collected with the help of the concave scraper 5. By rotating a rotating bead 6 at the end of the connecting rod 31, when the connecting rod 31 moves, the rotating bead 6 will rotate under the action of the friction force of contact with the inner wall of the storage groove 16. By providing a rubber pad 7 of soft material in the middle of the second pressing plate 17, when the second pressing plate 17 moves, the rubber pad 7 will directly contact the filter element 11.
