[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; 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.

[0020] Depend on Figure 1 , Figure 2 and Figure 3 The utility model provides a solid-liquid filtering device for sewage treatment. An overflow port is provided on the upper side of the right side wall of the filter box 100. A liquid storage tank 101 is fixedly connected to the right side wall of the filter box 100. The liquid storage tank 101 is connected to the filter box 100. The filtered water is stored and discharged through the liquid storage tank 101. A filter rack 102 is slidably connected to the inner wall of the overflow port. The filter rack 102 is used to separate solid impurities contained in the water. A sewage pipe 103 is fixedly connected to the front and rear side walls of the inner cavity of the filter box 100. The sewage pipe 103 is connected to the sewage pipe 103. 3 is convenient for injecting sewage into the inner cavity of the filter box 100. Both left and right sides of the bottom wall of the sewage pipe 103 are provided with sewage outlets. The bottom wall of the inner cavity of the sewage pipe 103 is inclined, and the inclined setting can avoid impurities remaining in a dead angle. The front and rear side walls of the inner cavity of the filter box 100 are fixedly connected with a drainage pipe 104, which is convenient for discharging solid impurities. The top wall of the drainage pipe 104 is provided with an inlet. The front end of the drainage pipe 104 is fixedly connected with a drainage valve 105. The drainage valve 105 can be opened to discharge impurities from the inner cavity of the filter box 100.

[0021] In this embodiment: sewage enters the inner cavity of the filter box 100 through the sewage pipe 103, and the sewage is discharged through the sewage outlets on both sides. The two sets of sewage outlets can disperse the sewage. Solid impurities such as sand, gravel, sludge, etc. in the sewage will sink to the bottom due to their own weight. The incoming water causes the liquid level to rise, and the liquid level moves to the overflow port for overflow, so that the upper layer of clear water is discharged into the inner cavity of the liquid storage tank, and filtered at the overflow of the filter rack 102 to avoid leakage of solid impurities. When the solid impurities are deposited to a certain thickness, the solid impurities are discharged by opening the impurity discharge valve 105, which can make the device convenient for overflow filtration of sewage and separate the solid impurities in the sewage from water, so as to avoid impurities clogging the filter screen and affecting the filtration efficiency.

[0022] A pushing auger 106 is provided on the rear side wall of the inner cavity of the filter box 100, and a motor 107 is fixedly connected to the rear side wall of the filter box 100, which is convenient for driving the pushing auger 106 to rotate through the motor 107. The output end of the motor 107 is connected to the pushing auger 106, and the pushing auger 106 is located in the inner cavity of the exhaust pipe 104.

[0023] In this embodiment, when too much impurities are accumulated and difficult to discharge, the motor 107 drives the pushing auger 106 to rotate, and the pushing auger 106 pushes the solid impurities to be discharged from the impurity discharge valve 105.

[0024] The left and right sides of the bottom wall of the inner cavity of the filter box 100 are both inclined, and the bottom end of the inclination is located at the inlet.

[0025] In this embodiment, the inclined setting facilitates the collection of settled solid impurities into the inner cavity of the impurity discharge pipe 104, thereby facilitating the discharge of impurities and avoiding the occurrence of dead corners that may cause impurities to remain.

[0026] A snap-in groove is provided on the top wall of the filter box 100 , and a snap-in frame 108 is slidably connected to the inner cavity of the snap-in groove. The snap-in frame 108 is used to support the filter mesh frame 102 , and the filter mesh frame 102 is arranged on the inner wall of the snap-in frame 108 .

[0027] In this embodiment: the card-joint frame 108 is provided to facilitate supporting the filter mesh frame 102 , and the card-joint frame 108 is plugged in and out to facilitate disassembly and assembly of the filter mesh frame 102 , which is beneficial for cleaning and maintenance of the filter mesh frame 102 .

[0028] The front and rear side walls of the inner cavity of the filter box 100 are evenly and fixedly connected with slow-flow strips 109, which facilitate blocking and slowing down the discharged sewage. The cross-section of the slow-flow strips 109 is triangular.

[0029] In this embodiment, the slow-flow strip 109 is provided to block the discharged sewage, reduce the flow of the sewage, and make it easier for solid impurities in the sewage to settle, which is beneficial to improving the separation effect of the device.
