[0027] For a better understanding of the present invention, the following embodiments are further explanations of the present invention, but the content of the present invention is not limited to the following embodiments.

[0028] like Figures 1 to 4 As shown, a sewage treatment filtering structure includes: a base 1, a processing box 2, a filtering component 3, a hanging plate 4 and a telescopic rod 5.

[0029] The treatment box 2 is fixed on the base 1, and the filter assembly 3 for filtering sewage is installed in the treatment box 2. The filter assembly 3 includes an outer frame plate 31, a filter side net 32 ​​and a filter bottom net 33. The outer frame plate 31 is installed in the treatment box 2 so as to be movable up and down. The filter side net 32 ​​and the filter bottom net 33 are both installed in the outer frame plate 31. The lower end of the filter side net 32 ​​is inclined toward the sewage flow direction in the treatment box 2. The filter bottom net 33 is arranged below the filter side net 32 ​​to receive impurities dropped from the filter side net 32. The sewage is filtered through the filter side net 32. The filtered impurities will stay on the filter side net 32, or fall onto the filter bottom net 33 under the action of gravity, which is convenient for later collection and cleaning; wherein, the filter side net 32 ​​is tilted toward the flow direction of sewage in the treatment box 2, which can not only increase the filtering area, but also facilitate the filtered impurities to fall on the filter bottom net 33; the filter bottom net 33 is fixedly connected to the bottom of the outer frame plate 31, and the filtered impurities are deposited on the filter bottom net 33. When the filter assembly 3 extends out of the top groove 21, the impurities on the filter bottom net 33 will be taken out together, which is convenient for cleaning the impurities. Among them, the filter bottom net 33 can be set horizontally or tilted at a certain angle. Different setting schemes can be selected according to the sewage state, which is simple and efficient. At the same time, the hanging plate 4 is connected to the top of the outer frame plate 31 and is located above the treatment box 2. The telescopic rod 5 is installed on the base 1 and the top of the telescopic rod 5 is connected to the hanging plate 4, which is used to drive the hanging plate 4 to move up and down. The top of the treatment box 2 is provided with a top groove 21 for the outer frame plate 31 to pass through.

[0030] In order to improve the efficiency and effect of sewage filtration, a plurality of filter assemblies 3 are arranged in the treatment box 2, and a hanging plate 4 is connected to the top of the outer frame plate 31 of each filter assembly 3, and the hanging plate 4 is installed on the base 1 so as to be movable up and down through a telescopic rod 5; and the hanging plate 4 is installed on the base 1 so as to be movable up and down through two telescopic rods 5, and the two telescopic rods 5 are respectively located on opposite sides of the treatment box 2. It can filter sewage multiple times, and the hanging plate 4 is driven to move up and down by the two telescopic rods 5, which is more stable and safe, and the telescopic rod 5 can be a cylinder or a hydraulic cylinder, which can achieve the desired purpose.

[0031] like Figure 2 and Figure 4 As shown, the outer frame plate 31 is an inverted U-shaped structure, and track bars 34 are provided on the two opposite outer side walls of the outer frame plate 31. The inner wall of the processing box 2 is provided with a track groove that cooperates with the track bar 34. The track bar 34 can slide inside the track groove to ensure stable sliding of the filter assembly 3.

[0032] At the same time, a resisting sealing strip 22 is provided at the bottom of the processing box 2 and is in contact with the bottom of the filter assembly 3 to ensure a good sealing effect.

[0033] like Figures 1 to 4 As shown, the top of the outer frame plate 31 is connected to the hanging plate 4 through a hanging component 6. The hanging component 6 includes a hanging head 61, a hook 62 and a push-in block 63. The hanging head 61 is arranged on the top of the outer frame plate 31, the hook 62 is arranged on the hanging plate 4, the hanging head 61 is hooked on the hook 62, the push-in block 63 is arranged on the side where the hook 62 contacts the hanging head 61, and the hanging head 61 is provided with a push-in slot 64 for accommodating the installation block to be inserted, so as to ensure the stability of the connection; the hanging head 61 and the hook 62 are detachably connected together, and both the hanging head 61 and the hook 62 are L-shaped structures, which are convenient for installation and disassembly.

[0034] The suspension assembly 6 further includes a limit screw 65 and a limit head 66. The limit screw 65 can be moved up and down and adjusted to be installed on the hanging plate 4 and located above the hanging head 61. The limit head 66 is fixed at the bottom of the limit screw 65. When the limit screw 65 moves downward, the limit head 66 abuts against the hanging head 61, and the hanging head 61 is limited and pressed against the hook 62 to prevent the hanging head 61 from being separated from the hook 62, thereby further improving the stability of the connection. The hanging plate 4 is provided with a threaded hole 41 that cooperates with the limit screw 65, and the bottom of the threaded hole 41 is provided with a clearance groove 67 for the limit head 66 to be embedded. When the filter assembly 3 is fully raised, the limit screw 65 can be loosened, the limit head 66 can be stored in the clearance groove 67, and then the hanging head 61 can be lifted upward to separate the insertion block and the insertion hole, and then the hanging head 61 can be separated from the hook 62, so that the filter assembly 3 can be removed.

[0035] When sewage passes through the filter assembly 3, the impurities therein will be intercepted by the filter side net 32, thereby filtering out the impurities, and these impurities will fall onto the filter bottom net 33 and gradually settle down. After a certain period of time, the personnel can start the telescopic rod 5 and extract the filter assembly 3 together with the impurities on the filter bottom net 33 from the inside of the treatment box 2 through the hanging plate 4, so as to remove the impurities.

[0036] The above is only a preferred implementation of the present utility model, which certainly cannot be used to limit the scope of rights of the present utility model. It should be pointed out that for ordinary technicians in this technical field, several improvements and changes can be made without departing from the principle of the present utility model, and these improvements and changes are also regarded as the protection scope of the present utility model.
