DETAILED DESCRIPTION

[0020] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0021] Embodiment 1:

[0022] like Figure 1-4 As shown, Figure 1 This is a schematic diagram of the overall structure of a high-temperature and high-efficiency filter according to the first embodiment of the utility model. Figure 2 It is a structural schematic diagram of the filtering device of the first embodiment of the utility model. Figure 3 This is a schematic diagram of the connection between the mounting plate and the mounting ring of the first embodiment of the utility model. Figure 4 It is a schematic diagram of the connection between the filter element and the mounting ring of the first embodiment of the utility model.

[0023] The utility model provides a high-temperature and high-efficiency filter: comprising a filter cartridge 101 and a mounting plate 102, and also comprising a filtering device, wherein the filtering device comprises a filter element 104, a mounting ring 105, a filter plate 106, a cleaning rod 107, a drive shaft 108, a driving assembly and a fixing assembly, wherein the driving assembly comprises a driving blade 110, a support shaft 111 and a supporting member, wherein the supporting member comprises a support rod 112 and a fixing ring 113, and the fixing assembly comprises a locking bolt 114 and a gasket 115. The above-mentioned scheme solves the problem that although the above-mentioned device reduces the workload of the main filter by setting a pre-filter, it is not convenient to regularly clean the first filter screen and the second filter screen, resulting in the filter residue in the air clogging the filter screen after long-term use, thereby making the filter element unable to filter the air. It can be understood that the present scheme can also be used to solve the problem of facilitating the installation of the filter cartridge.

[0024] In this embodiment, the filtered air drives the driving assembly to drive the cleaning rod 107 on the driving shaft 108 to clean the filter residue on the outside of the filter plate 106, thereby preventing the filter residue from clogging the filter plate 106.

[0025] The mounting ring 105 is fixedly mounted on the mounting disk 102 and is located in the mounting hole 103. A mounting groove 109 is provided in the mounting ring 105. The filter element 104 is embedded in the mounting groove 109. The filter plate 106 is mounted on the mounting disk 102 through the fixing assembly and is close to the mounting hole 103. The drive shaft 108 is rotatably mounted on the mounting disk 102 through the drive assembly and passes through the mounting disk 102. The cleaning rod 107 is fixedly mounted on the drive shaft 108 and is located outside the filter cartridge 101. Four groups of mounting holes 103 are provided in the mounting ring. A group of mounting rings 105 are provided in each group of mounting holes 103. The mounting rings 105 are provided with a plurality of mounting holes 103. The mounting groove 109 is an annular groove, the filter element 104 adopts high temperature resistant glass fiber filter paper, and a group of filter plates 106 are provided on the outside of each group of mounting holes 103, and the filter plates 106 are provided with filter holes. The filter plates 106 are made of polystyrene material and have heat insulation effect. At the same time, the filter plates 106 can increase wind resistance and protect the filter element 104. A brush is provided on the cleaning rod 107. When air is filtered through the filter plates 106 and the filter element 104, the driving shaft 108 is driven to rotate with the cooperation of the driving assembly. The rotation of the driving shaft 108 drives the cleaning rod 107 to rotate, and the filter residue on the outside of the filter plate 106 is cleaned, thereby avoiding the filter residue clogging the filter plate 106.

[0026] Secondly, the support shaft 111 is rotatably installed in the filter cartridge 101 through the support component and is fixedly connected to the drive shaft 108; the drive blade 110 is fixedly installed on the support shaft 111, the support shaft 111 coincides with the axis of the drive shaft 108, and the drive blade 110 is annularly welded on the support shaft 111. The drive blade 110 rotates under the drive of the airflow, and drives the support shaft 111 to rotate under the cooperation of the support component, and the support shaft 111 further drives the drive shaft 108 to rotate, thereby achieving the rotation effect of the drive shaft 108.

[0027] Again, the support rod 112 is fixedly installed in the filter cartridge 101; the fixing ring 113 is fixedly installed on the support rod 112 and is rotatably connected to the support shaft 111. The number of the support rods 112 is four groups, and they are annularly distributed on the outside of the fixing ring 113. The support shaft 111 is installed in the fixing ring 113 through a bearing.

[0028] Finally, the gasket 115 is sleeved on the locking bolt 114, and the locking bolt 114 passes through the filter plate 106 and is threadedly connected to the mounting disk 102. Two groups of gaskets 115 and locking bolts 114 are provided on each group of filter plates 106. Through the cooperation of the gasket 115 and the locking bolt 114, it is convenient to install and disassemble the filter plate 106, and then it is convenient to replace the filter element 104 in the mounting ring 105.

[0029] In this embodiment, when in use, the filter cartridge 101 is connected to the high-temperature air duct. When the air enters the filter cartridge 101, it first passes through the filter plate 106 for initial filtration, and then passes through the filter element 104 on the mounting ring 105 again. The filter element 104 can adsorb tar, soot, dust and lamp particles in the air. When the filtered air passes through the filter element 104, it blows the driving blade 110. The driving blade 110 starts to rotate under the action of the airflow, and drives the support shaft 111 to rotate on the fixing ring 113. The support shaft 111 is fixedly connected with the drive shaft 108, so as to drive the drive shaft 108 to rotate on the mounting disk 102. The rotation of the drive shaft 108 drives the cleaning rod 107 to rotate, and cleans the filter residue on the filter plate 106, thereby preventing the filter residue from clogging the filter plate 106.
