[0002] Wastewater treatment equipment can effectively treat domestic sewage and industrial wastewater in urban areas, preventing sewage and pollutants from flowing directly into water bodies. It is of great significance for improving the ecological environment, enhancing the city's image, and promoting economic development. The horizontal screw centrifuge is a type of screw discharge sedimentation centrifuge. The slag is pushed to the small end of the drum by the blades on the screw pusher and discharged through the discharge port. The liquid phase overflows through the overflow hole at the large end of the drum. This cycle continues to achieve the purpose of continuous separation.

[0003] Chinese patent application number 201820100946.9 discloses a horizontal screw centrifuge for sludge treatment, including a liquid phase outlet, a shock absorber, heat sink, a feeding screw, a drum, and a fixed base. The fixed base is located at the bottom of the centrifuge body, and a shell is located at the top of the centrifuge body. A support column is located at the upper end of the fixed base, and a shock absorber is installed inside the support column. This utility model has a scientific and reasonable structure, is easy to operate, and is equipped with heat sinks to accelerate the machine's heat dissipation and extend its service life. The shock absorber can buffer the mechanical damage caused by vibration during machine operation. The metal rubber filter screen can filter fine particles, improve liquid precision, and is corrosion-resistant, impact-resistant, and easy to clean. The grouting material can increase friction and achieve a shock-absorbing and stabilizing effect. The fixed base, feed inlet, liquid phase outlet, and solid phase outlet are all coated with silicon carbide powder, which can improve their wear resistance and extend their service life.

[0024] 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.

[0025] like Figure 1-6 As shown, this utility model provides a technical solution: including a main body component 1, a rotating drum component 2 is provided at the top inside the main body component 1, and a liquid filter component 3 is provided on one side of the bottom inside the main body component 1;

[0026] The main component 1 includes a machine base 101, and a housing 102 is fixedly installed on the top of the machine base 101. A liquid outlet 103 and a solid outlet 104 are respectively opened on both sides of the bottom surface of the housing 102.

[0027] The drum assembly 2 includes two bearing seats 201, and a drum body 202 is rotatably mounted between the two bearing seats 201. A spiral feeder is provided inside the drum body 202, and a liquid phase outlet 203 and a solid phase outlet 204 are respectively opened at both ends of the drum body 202.

[0028] The liquid filtration assembly 3 includes a liquid phase tube 301, a filter plate 302 is fixedly installed in the middle of the liquid phase tube 301, a collection box 303 is fixedly installed on one side of the liquid phase tube 301, the filter plate 302 includes an outer filter plate 3021, an inner groove is formed in the outer filter plate 3021, an inner filter plate 3022 is slidably installed in the inner groove, a sliding groove is formed on one side of the inner groove, a threaded rod 3023 is rotatably installed in the sliding groove, a connecting slider 3024 is threadedly sleeved on the rod body of the threaded rod 3023, and one side of the connecting slider 3024 is fixedly connected to one side of the inner filter plate 3022.

[0029] In this embodiment, drive motors 105 are fixedly installed on both sides of the top surface of the machine base 101. A belt 106 is driven to one end of the output shaft of the drive motor 105. Feed pipes 205 and transmission rods 206 are respectively provided at the center of both ends of the drum body 202. The drum body 202 is rotatably installed inside the machine housing 102. The top end of the liquid phase pipe 301 is fixedly connected to the bottom surface of the liquid outlet 103. The drive motor 105 provides power to the belt 106. One belt 106 drives the spiral feeder to move, while the other... A belt 106 drives the rotating drum 202 to move. The rotating drum 202 and the screw conveyor rotate at high speed in the same direction with a certain differential speed. The material is continuously introduced into the conveying screw conveyor through the feed pipe 205. After acceleration, it enters the rotating drum 202. Under the action of centrifugal force, the heavier solid phase is deposited on the wall of the rotating drum 202 to form a sludge layer. The conveying screw continuously pushes the deposited solid phase to one end of the rotating drum 202 and discharges it out of the machine through the solid outlet 104. The lighter liquid phase forms an inner liquid ring and is discharged from the liquid outlet at the other end of the rotating drum 202.

[0030] Both the liquid phase tube 301 and the collection box 303 have a connecting port 304 on their mating surfaces. The interior of the liquid phase tube 301 is interconnected with the interior of the collection box 303 through the connecting port 304. The separated solid phase can also enter the collection box 303 through the connecting port 304 under the action of the inclined filter plate 302, and the screened solid phase is collected by the collection box 303.

[0031] The filter plate 302 is inclined, and the bottom surface of the collection box 303 is threaded with a threaded cover 305. One end of the threaded rod 3023 extends to the outside of the liquid phase pipe 301, and a knob 3025 is fixedly installed at the extended end of the threaded rod 3023. The knob 3025 drives the threaded rod 3023 to rotate. The rotation of the threaded rod 3023 can drive the connecting slider 3024 threaded on it to move. The movement of the connecting slider 3024 can drive the inner filter plate 3022 to move. By controlling the movement of the inner filter plate 3022, the filter holes opened on the top surface of the inner filter plate 3022 and the outer filter plate 3021 can be changed from complete overlap to partial overlap, thereby changing the filter diameter. This allows the centrifuge to adapt to the liquid phase filtration needs of different sludge, improving the practicality of the machine.

[0032] In operation, the drive motor 105 provides power to the belt 106. One belt 106 drives the screw conveyor to move, while the other belt 106 drives the drum 202 to move. The drum 202 and the screw conveyor rotate at high speed in the same direction with a certain differential speed. The material is continuously introduced into the screw conveyor through the feed pipe 205, and after acceleration, it enters the drum 202. Under the action of centrifugal force, the heavier solids are deposited on the wall of the drum 202 to form a sludge layer. The conveying screw continuously pushes the deposited solids to one end of the drum 202 and discharges them out of the machine through the solid outlet 104. The lighter liquids form an inner layer. The liquid ring is discharged from the drain port at the other end of the drum body 202. The discharged liquid phase will enter the liquid phase pipe 301 through the liquid phase outlet 203. During the process of the liquid phase passing through the liquid phase pipe 301, the liquid phase is screened by the filter plate 302, so that the solid phase in the liquid phase is separated again, which enhances the separation effect between the solid phase and the liquid phase. The separated solid phase can also enter the collection box 303 through the connecting port 304 under the action of the inclined filter plate 302. The collection box 303 collects the screened solid phase. The collected solid phase can be discharged by opening the threaded cover 305 for centralized treatment.

[0033] Meanwhile, the screening aperture of the filter plate 302 can be adjusted according to screening requirements. Specifically, the knob 3025 is manually turned, which drives the threaded rod 3023 to rotate. The rotation of the threaded rod 3023 can drive the connecting slider 3024 threaded on it to move. The movement of the connecting slider 3024 can drive the inner filter plate 3022 to move. By controlling the movement of the inner filter plate 3022, the filter holes opened on the top surface of the inner filter plate 3022 and the outer filter plate 3021 can be changed from complete overlap to partial overlap, thereby changing the filter aperture. This allows the centrifuge to adapt to the liquid phase filtration requirements of different sludge, improving the practicality of the machine.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
