Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0024] Example

[0025] The utility model provides a municipal sewage filtering device, which aims to solve the technical problem that too much impurities adhere to the surface of the filter screen in the prior art will cause blockage and it is inconvenient to clean the surface of the filter screen;

[0026] The utility model provides a technical solution:

[0027] First, see Figure 1-Figure 3A municipal sewage filtering device comprises a filter box 1, one end of the filter box 1 is connected to an inlet pipe 101, sewage enters the filter box 1 through the inlet pipe 101, the end of the filter box 1 away from the inlet pipe 101 is connected to an outlet pipe 102, the sewage flows out through the outlet pipe 102 after being filtered, the filter box 1 is connected to a filter component 2, the filter component 2 is used to filter impurities in the sewage, the filter component 2 comprises a stirring wheel 201, a filter screen 202 located on one side of the stirring wheel 201, and a filter screen 202 located on one side of the filter screen 202. The pull plate 203 at the end, the stirring wheel 201 is located between the filter screen 202 and the water inlet pipe 101. After the sewage enters the filter box 1 from the water inlet pipe 101, it is first stirred by the stirring wheel 201. A motor 2011 is connected to one side of the filter box 1 and located at the position of the stirring wheel 201. The user turns on the motor 2011 to control the rotation of the stirring wheel 201. When the stirring wheel 201 rotates, it drives the sewage in the filter box 1 to flow, and guides the larger impurities in the sewage to the filter screen 202, so that the impurities in the sewage are blocked by the filter screen 202.

[0028] For further information, see Figure 1-Figure 3 , a limiting groove is connected to the inner side of the filter box 1 and at the position corresponding to the filter screen 202. When the filter screen 202 is inserted into the filter box 1, one end of the filter screen 202 is embedded in the limiting groove, which increases the stability of the connection of the filter screen 202 in the filter box 1 and prevents the filter screen 202 from tilting due to the water flow generated when the stirring wheel 201 rotates, allowing impurities in the sewage to directly enter the filter component 3. The end of the filter screen 202 away from the limiting groove passes through one side of the filter box 1 and is fixedly connected to the pull plate 203. After a period of time, the impurities in the sewage will be in the filter screen 202. 02 surface is clogged, the user can pull out the filter screen 202 by pulling the plate 203, so as to clean the impurities on the surface of the filter screen 202, a connecting block is connected between the pulling plate 203 and the filter screen 202, a card slot 1 is provided on the surface of the filter box 1 and at the position corresponding to the connecting block, the thickness of the connecting block is greater than the thickness of the filter screen 202, after the user pushes the filter screen 202 into the filter box 1, the connecting block is embedded in the card slot 1 to block the card slot 1 and prevent the sewage from flowing out of the card slot 1, and a fixing block 2031 is connected to the side of the pulling plate 203 close to the filter box 1.

[0029] Among them, see Figure 2-Figure 3The second card slot is provided inside the fixing block 2031, and both sides of the second card slot are slidably connected with trapezoidal blocks 2032. A spring 2033 is connected between the two sets of trapezoidal blocks 2032. A fixing slot is provided on the surface of the filter box 1 and at the position corresponding to the fixing block 2031. A trapezoidal slot is provided inside the fixing slot and at the position corresponding to the trapezoidal block 2032. When the filter screen 1 202 is pushed into the filter box 1, the fixing block 2031 on one side of the pull plate 203 enters the fixing slot. At the same time, the spring 2033 is compressed, and the two sets of trapezoidal blocks 2032 enter the second card slot. When one end of the filter screen 1 202 is against the inner side of the limiting slot, the trapezoidal block 2032 moves synchronously to the position of the trapezoidal slot. Due to the resilience of the spring 2033 embedded in the trapezoidal slot, one end of the filter screen 1 202 is fixed to one side of the filter box 1 through the trapezoidal block 2032, further increasing the connection stability of the filter screen 1 202 inside the filter box 1.

[0030] Finally, see Figure 1-Figure 2 A filter component 3 is connected to the inside of the filter box 1 and located on one side of the filter component 2. The sewage filtered by the filter mesh 202 flows to the filter component 3 through the mesh gaps between the filter mesh 202. The filter component 3 is used to further filter the sewage. An activated carbon filter layer 103 is connected to the inside of the filter box 1 and located between the filter component 3 and the outlet pipe 102. The sewage can remove the odor in the sewage while filtering harmful substances through the activated carbon filter layer 103, thereby improving the water quality. The filter component 3 is located between the filter component 2 and the activated carbon filter layer 103. The filter component 3 includes multiple groups of filter tubes 301 and filter balls 302 located inside the filter tubes 301. The multiple groups of filter tubes 301 are internally connected with limited block, which is used to filter The impurity ball 302 is limited. When the sewage flows into the filter tube 301, the impurity ball 302 rolls due to the flow of water. At this time, the sewage in the filter tube 301 flows downward from the gap between the inner side of the filter tube 301 and the impurity ball 302 when the impurity ball 302 rolls, and a part of the impurity in the filtered sewage passes through the filter mesh 202. The two ends of the inner part of the multiple groups of filter tubes 301 are connected to the limiting blocks. The limiting blocks prevent the impurity ball 302 from escaping from the filter tube 301 when the water flow is too large. The end of the filter tube 301 close to the activated carbon filter layer 103 is connected to the filter mesh 2 303. The density of the filter mesh 2 303 is less than the density of the filter mesh 202, so that the sewage left by the filter tube 301 is further dust-removed and filtered.

[0031] In addition, it should be added based on the above embodiments that the activated carbon filter layer 103 and the motor 2011 are prior art, and their internal working principles and operating procedures will not be described in detail here.

[0032] The working process of the utility model is as follows: when using the sewage filtering device, the user connects the water inlet pipe 101 to the sewage outlet, and then the user turns on the motor 2011. When the sewage enters the filter box 1 through the water inlet pipe 101, the stirring wheel 201 rotates to guide the impurities in the sewage in the filter box 1 to the filter screen 202. The sewage filtered by the filter screen 202 flows to the filter tube 301 through the mesh gaps between the filter screens 202. At this time, the filter balls 302 in the filter tube 301 roll in the filter tube 301 due to the water flow generated by the rotation of the stirring wheel 201. At the same time, the sewage passes through the inner side of the filter tube 301 and the filter balls 302 when rolling. The gap between the filter balls 302 flows toward the filter screen 2 303, and then the sewage flows through the filter screen 2 303 to the activated carbon filter layer 103, and then flows to the outlet pipe 102 through the activated carbon filter layer 103. When the user needs to clean the filter screen 1 202, the user pulls out the filter screen 1 202 through the pull plate 203. At this time, the two groups of trapezoidal blocks 2032 slide into the second card slot. The user pulls out the filter screen 1 202 for cleaning. After cleaning, the filter screen 1 202 is pushed into the filter box 1. When the two groups of trapezoidal blocks 2032 are embedded in the trapezoidal groove due to the resilience of the spring 2033, the filter screen 1 202 can be fixed.

[0033] The entire operation process is simple and convenient. Compared with the existing sewage filtering device, the utility model can quickly install and disassemble the filter screen one through the design of the fixed block, clean the filter screen one, and avoid blockage caused by excessive impurities adhering to the surface.
