Description

Technical Field

[0001] The utility model belongs to the technical field of filter screen installation, and specifically relates to a multi-polymer air catalyst filter screen. Background Art

[0002] An air catalyst filter is a filter that can absorb harmful gases and odors in the air. It usually uses catalyst materials (such as activated carbon) to absorb gases and use the catalyst to decompose harmful gases into harmless substances. In some industrial applications, it is often necessary to install multiple layers of filters in the equipment to achieve the purpose of purifying the gas.

[0003] Currently, many ways to install filters are to place them directly in a filter chamber or filter box. Generally, the capacity of a filter chamber or filter box is slightly larger than the filter element. This will cause some harmful gases to pass through the gap between the filter element and the filter chamber instead of directly passing through the filter element during use. As a result, these harmful gases cannot be effectively filtered, reducing the filtering effect on harmful air. Utility Model Content

[0004] The purpose of this utility model is to provide a poly-air catalyst filter screen, which can effectively seal the filter element, reduce the gap between the filter element and the filter chamber, avoid the leakage of harmful gases, and prevent the problem of ineffective filtering.

[0007] The fixing assembly includes a connecting plate fixedly connected to the end face of the pressure plate, a same screw is threadedly connected between two connecting plates on the same side, the threads on the side walls of the screw are symmetrically arranged in opposite directions, a support plate is fixedly connected to the end face of the upper pressure plate, the top end of the screw is rotatably connected to the support plate, and the bottom end of the screw is fixedly connected to a hexagonal block.

[0008] The side walls of the pressure plate close to the filter element are respectively fixedly connected with sealing strips, and the sealing strips are all against the corners of the pressure plate.

[0009] The upper and lower side walls of the installation groove are respectively provided with limiting grooves, and the limiting plates are movably connected to the limiting grooves.

[0010] The limiting assembly includes a fixing plate fixedly connected to the side wall of the rectangular frame, a baffle is arranged on the lower side of the fixing plate, the baffle is L-shaped, the top surface of the baffle is equipped with bolts, the top surface of the fixing plate is provided with a plurality of through holes, and the bolts are adapted to the through holes.

[0011] The pressure plate and the limiting plate are both flush with the side wall of the filter element.

[0012] The technical effects achieved by this utility model are:

[0022] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0023] like Figure 1-Figure 6 As shown, a polymer air catalyst filter comprises a rectangular frame 1, the front and rear side walls of the rectangular frame 1 are respectively provided with mounting grooves 2, a filter element 3 is arranged in the mounting groove 2, and pressure plates 4 are respectively arranged on the upper and lower sides of the filter element 3 in the rectangular frame 1, and the side walls of the pressure plate 4 away from the filter element 3 are respectively fixedly connected to two limit plates 5, the limit plates 5 are movably connected to the rectangular frame 1, fixed components are arranged between the two ends of the pressure plate 4, and a limit component is arranged on the front side wall of the rectangular frame 1.

[0024] Among them, the rectangular frame 1 used in this scheme can be used as a sealed chamber or a filter box. In practical applications, the number of rectangular frames 1 can be set to multiple and used in stacking. The filter element 3 of each layer can be set to different filtering functions. The connection method between the rectangular frames 1 can be in the form of screws, welding, clamping, etc.

[0025] like Figure 2 and Figure 5 As shown, the fixing assembly includes a connecting plate 6 fixedly connected to the end face of the pressure plate 4, a same screw rod 7 is threadedly connected between two connecting plates 6 on the same side, the threads on the side walls of the screw rod 7 are symmetrically arranged in opposite directions, a support plate 8 is fixedly connected to the end face of the upper pressure plate 4, the top end of the screw rod 7 is rotatably connected to the support plate 8, and the bottom end of the screw rod 7 is fixedly connected to a hexagonal block 9.

[0026] The side walls of the pressing plate 4 close to the filter element 3 are respectively fixedly connected with sealing strips 10 , and the sealing strips 10 are all against the corners of the pressing plate 4 .

[0027] Specifically, the hexagonal block 9 can be driven by an electric wrench, a manual wrench or other methods; in addition, during use, the screw 7 can also be replaced by a one-way screw 7, so that the pressure plate 4 and the limit plate 5 on one side are in a fixed state, and during the rotation of the one-way screw 7, it is only necessary to drive the pressure plate 4 and the limit plate 5 on one side to move closer to the other side.

[0028] like Figure 4 As shown, the upper and lower side walls of the installation groove 2 are respectively provided with limiting grooves 11, and the limiting plates 5 are movably connected to the limiting grooves 11. By providing the limiting grooves 11, the limiting plates 5 can be limited and accommodated, and can also play a sealing role.

[0029] like Figure 6As shown, the limiting assembly includes a fixing plate 12 fixedly connected to the side wall of the rectangular frame 1, a baffle 13 is arranged on the lower side of the fixing plate 12, the baffle 13 is L-shaped, and bolts 14 are assembled on the top surface of the baffle 13. A plurality of through holes 15 are opened on the top surface of the fixing plate 12, and the bolts 14 are adapted to the through holes 15.

[0030] Specifically, when the distance of the baffle 13 needs to be adjusted, first loosen the bolt 14 to remove the baffle 13, then insert the bolt 14 into the specified through hole 15 according to the required distance, and tighten the nut to fix the baffle 13, so as to adapt to filter elements 3 of different widths and sizes and play a limiting role thereon.

[0031] like Figure 3 As shown, the pressing plate 4 and the limiting plate 5 are flush with the side wall of the filter element 3. After the filter element 3 is fixed, the pressing plate 4 and the limiting plate 5 are tightly attached to the surface of the filter element 3, and the squeeze force of the screw 7 makes the gap smaller, and harmful gases cannot pass through.

[0032] The working principle of the utility model is as follows: when the filter element 3 needs to be installed, the filter element 3 is first inserted into the inner side of the rectangular frame 1 through the installation groove 2, so that the filter element 3 is located between the pressure plates 4 on both sides, and at the same time, the other side of the filter element 3 is against the baffle 13, and then the hexagonal blocks 9 at the four corners are rotated to drive the screw 7 to rotate, and the reverse thread on the screw 7 is used to drive the pressure plate 4 to move relatively, so as to squeeze and fix the filter element 3, and at the same time, the sealing strip 10 and the limit plate 5 can be used to seal the edge position of the filter element 3 to avoid leakage of harmful gases through the gaps, thereby improving the purification efficiency of harmful gases.

[0033] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
