[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1 to 3 This embodiment of a solid-liquid separation type energy-saving and environmentally friendly water treatment equipment includes a treatment tank 1, a horizontal sealing cover 2 on the upper side of the treatment tank 1, a separation mechanism 3 for rapid solid-liquid separation of water on the upper side of the treatment tank 1, and a liquid inlet mechanism 4 for disinfecting the water after solid-liquid separation on the sealing cover 2.

[0021] The separation mechanism 3 includes electric push rods 301 fixed on the left and right sides of the processing tank 1. One end of the output shaft of each of the two electric push rods 301 passes through the sealing cover 2 and extends to the upper side of the sealing cover 2 and is fixed with a connecting plate 302. The bottom end of each of the two connecting plates 302 is vertically fixed with a pull rod 303. One end of each of the two pull rods 303 passes through the sealing cover 2 and extends into the interior of the processing tank 1 and is fixed with a pressing component 304 for pressing the water. A support block 305 is fixed on the outer side of the output shaft of each of the two electric push rods 301. A secondary filter plate 306 is fixed inside the processing tank 1. A primary filter frame 307 is fixed at the center of the upper surface of the secondary filter plate 306. A stirring component 308 for stirring and centrifuging the water is provided on the upper side of the sealing cover 2.

[0022] In this embodiment, the separation mechanism 3 is designed to drive the connecting plate 302 and the pull rod 303 through the electric push rod 301, thereby causing the pressing member 304 to apply pressure to the water, achieving efficient solid-liquid separation. At the same time, in conjunction with the use of the primary filter frame 307 and the secondary filter plate 306, it can effectively remove solid particles of different sizes. The stirring member 308 uses centrifugal force to further accelerate the water separation process. The entire design is compact and highly automated, which not only improves the efficiency of solid-liquid separation, but also ensures that the treated water is purer, demonstrating the advantages of high efficiency, reliability and easy control.

[0023] The pressing component 304 includes a pressing block 3041 that slides against the inner wall of the processing box 1 and the outer surface of the primary filter frame 307. The upper surface of the pressing block 3041 has eight sets of two water-permeable holes 3042. The two water-permeable holes 3042 in each set are distributed in a straight line along their radius. A support base 3043 is fixed between the two water-permeable holes 3042 in each set. Two shafts 3046 are rotatably connected inside each support base 3043. The two shafts 3046 on each support base 3043 are rotatably connected to a connecting rod 3044 via a torsion spring. One end of the connecting rod 3044 is fixed with a sealing plate 3045 that is in contact with the lower surface of the pressing block 3041 and faces the direction of the water-permeable holes 3042.

[0024] It should be noted that the pressing component 304 applies pressure through the pressing block 3041, which slides against the inner wall of the processing tank 1 and the outer surface of the primary filter frame 307, effectively promoting the solid-liquid separation process. The eight sets of water-permeable holes 3042 on the pressing block 3041, with two holes in each set distributed in a straight line along the radius line, ensure that water can pass through evenly and efficiently. The support base 3043 and its internally rotating shaft 3046 and torsion spring mechanism, together with the design of the connecting rod 3044 and the sealing plate 3045, not only enhance the stability of the structure, but also ensure the sealing effect through dynamic adjustment, preventing solid particles from entering the water-permeable holes 3042 and causing blockage, while allowing liquid to pass through smoothly, improving the overall separation efficiency and reliability of the equipment, and demonstrating the advantages of high efficiency, strong adaptability and easy maintenance.

[0025] The stirring component 308 includes a motor 3081 fixed to the upper surface of the sealing cover 2. A hollow rod 3082 with one end extending through and to the lower side of the primary filter frame 307 is rotatably connected to the center of the upper surface of the sealing cover 2 via a bearing. Gears 3083 that mesh with each other are fixed to the outer side of the hollow rod 3082 on the upper side of the sealing cover 2 and the outer side of the motor 3081. A stirring blade A3084 is fixed to the outer side of the hollow rod 3082 and between the sealing cover 2 and the secondary filter plate 306.

[0026] In this embodiment, the stirring element 308 achieves efficient stirring of the sewage treatment process by driving the gear 3083 fixed to the outside of the hollow rod 3082 with a motor 3081 installed on the sealing cover 2. The hollow rod 3082 passes through the sealing cover 2 and extends to the lower side of the primary filter frame 307, on which stirring blades A3084 are fixed. Under the drive of the motor 3081, it rotates, effectively promoting the separation of solid particles and liquid in the sewage, and ensuring the uniform distribution of water flow and treatment efficiency. It is not only compact in structure and stable in operation, but also improves the stirring effect through precise mechanical transmission, enhances the efficiency of solid-liquid separation, and embodies the advantages of high efficiency, high reliability and easy operation.

[0027] It is understood that the hollow rod 3082 includes rod A and rod B, which are slidably connected and do not detach from each other. Furthermore, rod A can rotate with rod B and can move up and down inside rod B. Therefore, a limiting strip is fixed on the outside of rod A, and a limiting groove is fixed on the inner wall of rod B, so that they are positioned to facilitate the movement of the sealing cover 2.

[0028] The primary filter frame 307 is a hollow cylinder with missing upper and lower surfaces. The upper surface of the secondary filter plate 306 has a ring-shaped filter port, and a filter screen is fixed inside the filter port. The upper surface of the sealing cover 2 has two movable ports A for the output shafts of two electric push rods 301 to pass through and two movable ports B for the pull rods 303 to pass through. The electric push rods 301 and movable ports A are fitted with clearance, and the pull rods 303 and movable ports B are fitted with clearance. The outer diameter of the support block 305 is larger than the inner diameter of the movable ports A.

[0029] In this embodiment, the hollow cylindrical structure of the primary filter frame 307 with missing upper and lower surfaces, combined with the filter screen in the annular filter port of the secondary filter plate 306, effectively classifies and filters particles of different sizes in wastewater, thereby improving the solid-liquid separation effect.

[0030] The liquid inlet mechanism 4 includes a liquid storage tank 401 fixed to the upper surface of the sealing cover 2. A water pump 402 is fixed to the front of the liquid storage tank 401. A water inlet pipe 403 is fixedly connected to the water inlet end of the water pump 402. One end of the water inlet pipe 403 passes through and extends into the liquid storage tank 401. A water outlet pipe 404 is fixedly connected to the water outlet end of the water pump 402. One end of the water outlet pipe 404 is rotatably connected to the hollow rod 3082 through a sealed bearing. Two sets of liquid outlet heads 405 are fixedly connected to the outside of the hollow rod 3082 and located below the secondary filter plate 306. A slide table 406 is fixed inside the treatment box 1 and located below the secondary filter plate 306. A stirring blade B407 is fixed to the outside of the hollow rod 3082 and located below the slide table 406.

[0031] It should be noted that the design of the liquid inlet mechanism 4 involves fixing the liquid storage tank 401 and the water pump 402 to the sealing cover 2, and using the water inlet pipe 403 and the water outlet pipe 404 to transport the disinfectant from the liquid storage tank 401 to the hollow rod 3082. The disinfectant is then evenly sprayed onto the sliding table 406 area inside the treatment tank 1 through two sets of liquid outlet heads 405. This design cleverly incorporates the stirring blades B407, which fully stir the water as it flows under the secondary filter plate 306, ensuring that the disinfectant and sewage can be mixed efficiently and improving the disinfection effect. The sealed bearing connection between the hollow rod 3082 and the water outlet pipe 404 ensures the sealing of the liquid transmission and the flexibility of the rotating parts. Overall, this design not only achieves precise dosing and efficient mixing of the disinfectant, but also enhances the overall efficiency and quality of sewage treatment, demonstrating the advantages of compact structure, stable operation, and excellent treatment effect.

[0032] The upper surface of the slide table 406 has a funnel-shaped water tank with an inward concave shape from top to bottom. Each set of liquid outlets 405 has four outlets, and both outlets 405 face the water tank. The back of the treatment box 1 has an inlet and an outlet from top to bottom.

[0033] In this embodiment, the slide table 406 is designed with a water tank with a funnel-shaped cross-section. This concave structure helps to guide the water flow to concentrate and effectively discharge, ensuring that the treated water can flow smoothly. Each set of liquid outlets 405 is provided with four outlets, which are oriented towards the water tank to ensure that the disinfectant can be evenly distributed and fully contact the sewage, thereby improving the subsequent mixing efficiency and treatment effect.

[0034] The working principle of the above embodiments is as follows:

[0035] After the water to be treated enters the treatment tank 1 through the inlet, the motor 3081 starts, driving the hollow rod 3082 and the stirring blades A3084 mounted on it to rotate, stirring the water entering the treatment tank 1. During the stirring process, the water is subjected to centrifugal force, passing through the primary filter frame 307 and reaching the space outside it. This process removes larger solid particles and improves the efficiency of the primary separation through centrifugal force. Then, the electric push rod 301 operates, pushing the connecting plate 302 and the pull rod 303 downward, causing the pressing block 3041 in the pressing member 304 to apply pressure to the water. Under the pressure, the water is forced through the water permeable hole 3042, further realizing solid-liquid separation, and undergoing a second filtration through the secondary filter plate 306 to ensure that even smaller particles can be effectively separated. To facilitate the upward movement of the pressing block 3041, a sealing plate 3045 rotated by a torsion spring is provided at the water permeable hole 3042, allowing it to move upward. Under the force of the water flow, the sealing plate 3045 is pushed open to ensure the smooth movement of the pressing block 3041. After secondary solid-liquid separation, the water pump 402 in the storage tank 401 draws out the disinfectant, which is then transported to the hollow rod 3082 through the inlet pipe 403 and outlet pipe 404. The disinfectant is then sprayed onto the slide table 406 through the outlet head 405 on the hollow rod 3082. The hollow rod 3082 rotates due to the rotation of the motor 3081, further agitating the disinfectant onto the slide table. The water flowing on 406 makes initial contact. After the water reaches the lower space of the treatment tank 1, it is stirred by the stirring blade B407 to fully mix with the disinfectant. The water undergoes a second treatment after the initial mixing treatment, which can effectively improve the efficiency of water treatment. Then the water is discharged from the outlet. When it is necessary to clean the treatment tank 1, the output shaft of the electric push rod 301 moves upward continuously, which can make the support block 305 lift the sealing cover 2, so that the inside of the treatment tank 1 can be cleaned.
