[0001] The invention relates to the technical field of water treatment equipment, in particular to water treatment equipment with two-stage solid-liquid separation function. Background Art

[0002] Water treatment methods include physical treatment and chemical treatment. Humans have been treating water for many years. Physical methods include using filter materials with different pore sizes in water treatment equipment to remove impurities from the water through adsorption or barrier methods. The more important adsorption method is adsorption with activated carbon. The barrier method is to pass water through the filter material to prevent larger impurities from passing through, thereby obtaining cleaner water.

[0003] Most traditional water treatment equipment uses a single filter to separate solid impurities from sewage, and is unable to perform multiple separations of impurities in sewage, resulting in smaller suspended particles being discharged directly with the sewage, polluting the surrounding environment, and thus being unable to properly reuse the sewage. At the same time, when using the filter for filtration, traditional water treatment equipment is unable to clean the filter in real time, which can easily cause the mesh to become clogged, affecting the normal solid-liquid separation of impurities in sewage, and directly resulting in poor solid-liquid separation in sewage. To this end, a water treatment equipment with a two-stage solid-liquid separation function is proposed. Summary of the invention

The left side of the first treatment box 2 is fixedly connected with a controller.

[0027] Working principle: the user fixes the external sewage pipe on the docking pipe 6, and then the sewage is quickly transported to the first treatment box 2 through the docking pipe 6. At this time, the filter screen 5 on the annular sealing plate 4 in the first treatment box 2 performs preliminary filtering on the solid impurities in the sewage. Then, the sewage that has undergone preliminary solid-liquid separation is quickly transported to the second treatment box 3 through the drain pipe 7 with the assistance of the guide seat 15 and the first guide inclined plate 16. At this time, the filter screen 5 on the annular sealing plate 4 in the second treatment box 3 performs secondary filtering on the solid impurities in the sewage. At the same time, since the mesh aperture of the upper filter screen 5 is larger than the mesh aperture of the lower one, the two-stage filtration method is used to quickly separate the solid impurities of different specifications in the sewage from the sewage, effectively avoiding the single-aperture filter screen 5 from being unable to block the smaller solid impurities. Then the sewage is quickly discharged through multiple sets of installed pipes;

[0028] At the same time, the user turns on the motor 113 through the controller. With the assistance of the two sets of first sprockets 116 arranged on the first processing box 2, the motor 113 can drive the first auxiliary shaft 115 to rotate, and with the assistance of the two sets of second sprockets 118 and the gear 119, the two sets of cleaning rollers 117 in the first processing box 2 can be driven to rotate. At the same time, with the assistance of the first synchronous wheel 1111 and the second synchronous wheel 1113, the fixed shaft 1112 can be synchronously driven to rotate. Since the driving principles of the guide frame 114 and the cleaning roller 117 on the first processing box 2 and the second processing box 3 are the same, and only rely on the motor 113 to drive The source can make the four groups of cleaning rollers 117 rotate in opposite directions in pairs, and can drive the two groups of guide frames 114 to rotate continuously at the same time. With the assistance of the vertical plate 111, the vertical groove and the connecting block 112, the annular sealing plate 4 and the filter screen 5 can be driven to swing synchronously in the left and right directions continuously with the movable axis as the center, so that the solid impurities blocked on the filter screen 5 are constantly shaken to avoid accumulation on the filter screen 5 and affecting the filtering effect. At the same time, the continuously rotating cleaning rollers 117 can quickly brush away the fine impurities clogging the mesh of the continuously swinging filter screen 5, so that the filter screen 5 can continue to remain transparent, further improving the solid-liquid separation effect of sewage.

[0029] However, as is well known to those skilled in the art, the working principles and wiring methods of the controller and the motor 113 are commonplace, and are conventional means or common knowledge, and will not be elaborated here.
