Technical Field

[0001] The utility model relates to the technical field of water treatment equipment, in particular to an assembled M-shaped filter plate for a filter tank. Background Art

[0002] Nitrogen in wastewater can promote the massive growth of algae, causing eutrophication of water bodies, consuming dissolved oxygen in the water, leading to the destruction of the water ecosystem, and ultimately causing the death of a large number of aquatic organisms. The treatment of nitrogen-containing wastewater has been widely valued both at home and abroad, and the existing sewage treatment systems have been upgraded. Denitrification filters have been widely used due to their high efficiency and economic applicability in denitrification. However, the even distribution of water and air greatly affects the treatment effect of the denitrification filter. Therefore, the research and development of convenient and efficient distribution devices has attracted widespread attention.

[0003] Traditional denitrification filters generally use integrally cast filter plates, filter heads or filter bricks. Both are prefabricated parts and cannot be modified or adjusted according to the actual situation on site. Therefore, the construction requirements of the denitrification filter body are relatively high. Any dimensional deviation or deformation will cause installation, and the pool bottom needs to be leveled before installation. The flatness deviation will greatly affect the uniformity of water and air distribution.

[0004] The invention proposes an assembled M-type filter plate for a filter tank in order to solve the above problems. Utility Model Content

The water is then diffused to the filter material layer through the cross hole at the top. The threaded action between the bolt and the connecting rod allows the bolt to fit tightly with the arc groove, which can limit the position of the semicircular ball to prevent rotation, thereby improving the stability of the splicing of the first M-type filter plate and the second M-type filter plate.

[0020] 2. By setting up a fixing mechanism, the entire M-type filter plate can be quickly fixed on the surface of the pull rod, which is convenient for limiting the position of the M-type filter plate. By pressing the cap inward to compress the first spring and the second spring, and at the same time utilizing the cooperation between the ball, the fixing ring, the connecting block and the cap, the connecting block can be driven to move outward in the fixing block, thereby releasing the limit of the fixing block on the steel ball, thereby separating the clamping block from the steel ball, and the M-type filter plate can be disassembled and replaced.

The provision of the fixing blocks 203 improves the stability of the M-type filter plate.

[0036] The fixing block 203 is internally slidably connected to a connecting block 204. One end of the connecting block 204 is fixedly connected to a first spring 205. The end of the first spring 205 away from the connecting block 204 is fixedly connected to a cap 206. The inner wall of the cap 206 is slidably connected to the connecting block 204.

Then, the bolt 104 is rotated, and the threaded action between the bolt 104 and the connecting rod 105 is used to make the bolt 104 fit tightly with the arc groove 103, so that the position of the semicircular ball 106 can be limited to prevent rotation, thereby improving the stability of the first M-shaped filter, 101 and the second M-shaped filter plate 108 being spliced ​​together;

[0040] Secondly, the entire M-type filter plate is taken out from the denitrification filter tank 201, and then the cap 206 is pressed inward to compress the first spring 205 and the second spring 209. At the same time, the cooperation between the ball 207, the fixing ring 208, the connecting block 204 and the cap 206 can be used to drive the connecting block 204 to move outward in the fixing block 203, thereby releasing the limit of the fixing block 203 on the steel ball 212, thereby disengaging the clamping block 211 from the steel ball 212, and then the M-type filter plate can be disassembled and replaced.
