The outer wall of the driving wheel 73 is meshed with a transmission belt 74. The inner surface of the transmission belt 74 is movably connected with a driven wheel 75. The left side of the driven wheel 75 is fixedly connected with a rotating shaft 76. The left end of the rotating shaft 76 is fixedly connected with a centrifugal tank 77. The outer wall of the centrifugal tank 77 is fixedly connected with a plurality of filter meshes 78. The upper surface of the mounting seat 2 is fixedly connected with a tank body 4. The upper side of the outer wall of the tank body 4 is fixedly connected with a water inlet pipe 5. The left side of the mounting seat 2 is fixedly connected with a feed pipe 14. The upper surface of the base 1 is fixedly connected with a support plate 8. By means of the motor 71, the driving shaft 72 can be driven to rotate. The driving shaft 72 drives the driving wheel 73 to rotate. The driving wheel 73 drives the transmission belt 74 to rotate, thereby driving the driven wheel 75 to rotate. The driven wheel 75 drives the rotating shaft 76 to rotate, thereby driving the centrifugal tank 77 to rotate to separate and filter the materials in the centrifugal tank 77. The filtered liquid will be discharged from the inside of the device through a liquid extraction pump 10.

[0025] As Figures 4 - 5As shown in the figure, the utility model provides a technical solution: Preferably, a discharging mechanism 13 is arranged inside the tank body 4. The discharging mechanism 13 includes a rotating column 137. A scraping plate 132 is fixedly connected to the outer wall of the rotating column 137. A plurality of clamping blocks 133 are fixedly connected to the left end of the outer wall of the rotating column 137. A clamping plate 134 is clamped to the outer wall of the clamping block 133. A connecting block 135 is fixedly connected to the lower surface of the clamping plate 134. An electric telescopic rod 136 is fixedly connected to the lower surface of the connecting block 135. The lower end of the electric telescopic rod 136 is fixedly connected to the base 1. The electric telescopic rod 136 is electrically connected to the controller 3 and is electrically connected to an external power supply. A transmission mechanism 131 is arranged at the left end of the rotating column 137. The transmission mechanism 131 includes a driving motor 1311. A rotating rod 1312 is fixedly connected to the output end of the driving motor 1311. A spiral rod 1314 is fixedly connected to the right end of the rotating rod 1312. A guiding plate 1313 is rotatably connected to the outer wall of the rotating rod 1312. The outer wall of the rotating rod 1312 is rotatably connected to the rotating column 137. The outer wall of the guiding plate 1313 is fixedly connected to the rotating column 137. The outer wall of the spiral rod 1314 is rotatably connected to the rotating column 137. An outlet pipe 1315 is fixedly connected to the left end of the rotating column 137. A valve is arranged inside the outlet pipe 1315. A liquid extraction pump 10 is fixedly connected to the lower side of the inner wall of the tank body 4. A liquid extraction pipe 11 is fixedly connected to the input end of the liquid extraction pump 10. A liquid discharge pipe 12 is fixedly connected to the output end of the liquid extraction pump 10. Three spray heads 9 are fixedly connected to the lower end of the water inlet pipe 5. By starting the electric telescopic rod 136, the electric telescopic rod 136 will drive the connecting block 135 to rise or fall, thereby driving the clamping plate 134 to move. The clamping plate 134 cooperates with the clamping block 133 to drive the rotating column 137 to rotate, thereby driving the scraping plate 132 to rotate. When the device is filtering and separating, the opening of the scraping plate 132 faces downward, which can prevent unseparated materials from entering the rotating column 137. After centrifugation is completed, the rotating column 137 can be rotated to drive the scraping plate 132 to rotate, so that the opening of the scraping plate 132 faces upward to scrape the materials and ensure that the materials enter the rotating column 137. Then, through the driving motor 1311, the rotating rod 1312 is driven to rotate, thereby driving the spiral rod 1314 to rotate. The materials will be concentrated in front of the outlet pipe 1315 by the guiding plate 1313, which is convenient for discharging the materials. When the rotating column 137 rotates to make the outlet pipe 1315 at the lowest position, the valve inside the outlet pipe 1315 is opened, and then the materials will automatically be discharged from the outlet pipe 1315. Finally, water is added into the device through the water inlet pipe 5. The scraping plate 132 cooperates with the rotating mechanism 7 to clean the debris on the inner wall of the centrifugal tank 77, which can prevent the debris from corroding the device due to long-term non-cleaning.

[0026] Both the electric telescopic rod and the controller are prior arts and will not be described in detail here.

[0027] Next, specifically describe the working principle of the combined sealing device of the horizontal scraper centrifuge.

[0028] As Figures 1 - 5 shown, the material is now added into the device through the feed pipe 14, and then the motor 71 is started. The motor 71 can drive the drive shaft 72 to rotate, the drive shaft 72 drives the drive wheel 73 to rotate, the drive wheel 73 drives the conveyor belt 74 to rotate, thereby driving the driven wheel 75 to rotate, and the driven wheel 75 drives the rotating shaft 76 to rotate, thereby driving the centrifugal tank 77 to rotate to separate and filter the material in the centrifugal tank 77. The filtered liquid will be discharged from the device through the liquid extraction pump 10. By starting the electric telescopic rod 136, the electric telescopic rod 136 will drive the connecting block 135 to rise or fall, thereby driving the clamping plate 134 to move. The clamping plate 134 cooperates with the clamping block 133 to drive the rotating column 137 to rotate, thereby driving the scraping plate 132 to rotate. When the device is filtering and separating, the opening of the scraping plate 132 faces downward, which can prevent the unseparated material from entering the rotating column 137. After centrifugation, the rotating column 137 can be rotated to drive the scraping plate 132 to rotate, so that the opening of the scraping plate 132 faces upward to scrape the material to ensure that the material enters the rotating column 137. Then, through the driving motor 1311, the rotating rod 1312 is driven to rotate, thereby driving the screw rod 1314 to rotate. The material will be concentrated in front of the discharge pipe 1315 by the guide plate 1313, which is convenient for discharging the material. When the rotating column 137 rotates to make the discharge pipe 1315 at the lowest position, the valve inside the discharge pipe 1315 is opened, and then the material will automatically be discharged from the discharge pipe 1315. Finally, water is added into the device through the water inlet pipe 5. The scraping plate 132 cooperates with the rotating mechanism 7, so that the scraping plate 132 can clean the debris on the inner wall of the centrifugal tank 77, and can prevent the debris from corroding the device due to long-term non-cleaning.

[0029] The above has generally described the present invention in detail, but based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, the modifications or improvements without departing from the spirit of the present invention are within the protection scope of the present invention.
