The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0035] The following describes an embodiment of the utility model based on its overall structure.

A drain pipe 2 is provided on the other side of the device body 1 so that the liquid can be discharged through the drain pipe 2. Second baffles 10 are installed on both sides of the inside of the feed hopper 5. The bottom of the second baffle 10 is arc-shaped and the top of the second baffle 10 is smooth.

[0039] See also Figure 2 and Figure 4 The filter assembly 9 includes a movable shaft 903 and a connecting shaft 906 disposed inside the device body 1 through a bearing, an inclined plate 901 installed on one side of the inside of the device body 1, and a driving pulley 908 sleeved on one end of the roller shaft 11. A first filter screen 902 is installed at the bottom of the inclined plate 901, and a second filter screen 905 is installed on one side of the first filter screen 902. A scraper plate 904 is installed at the bottom of the movable shaft 903 and the connecting shaft 906. The bottoms of the two scraper plates 904 are in contact with the first filter screen 902 and the second filter screen 905 respectively. When the movable shaft When 903 and the connecting shaft 906 rotate clockwise, they will drive the scraper plate 904 to rotate, and the scraper plate 904 will drive the fixed impurities accumulated on the first filter screen 902 to move.

The outer wall of the rotating shaft 804 is sleeved with a driving bevel gear 810, which meshes with the driven bevel gear 809. The diameter of the driving bevel gear 810 is greater than the diameter of the driven bevel gear 809, which can increase the rotation speed of the driven bevel gear 809, so that the second rotating shaft 807 can rotate quickly. When the first rotating shaft 804 rotates, it will drive the driving bevel gear 810 to rotate, and then drive the driven bevel gear 809 to rotate, and then drive the second rotating shaft 807 to rotate, and then drive the fan blades 808 to rotate.

[0042] Specifically, one end of the first rotating shaft 804 extending to the outside of the air intake box 803 and the outer wall of the driving shaft 6 are both sleeved with a first sprocket 801, and a first chain 802 is meshed and connected between the two first sprockets 801, an air guide pipe 811 is connected between the air intake box 803 and the air guide plate 812, and a plurality of nozzles 813 are installed at the bottom of the air guide plate 812, and an air inlet 805 is opened at the top of the air intake box 803. A plurality of nozzles 813 are equidistantly distributed at the bottom of the air guide plate 812, and the nozzle 813 is located directly above the first filter 902 and the second filter 905, so that external air enters the air intake box 803 through the air inlet 805, and then enters the air guide plate 812 through the air guide pipe 811, and enters the nozzle 813, and then is sprayed out through the nozzle 813, so that the liquid attached to the first filter 902 and the second filter 905 can be blown off.

[0043] Embodiment 2:

[0044] On the basis of the above-mentioned first embodiment, in order to ensure that the solid impurities can smoothly fall onto the inclined plate 901 and then slide into the first filter screen 902 through the inclined plate 901, the following structure is provided.

[0045] Specifically, the filter assembly 9 also includes a first baffle 913 installed on the upper part of the device body 1, and the bottom of the first baffle 913 is arc-shaped. The first baffle 913 is arranged so that solid impurities can fall smoothly onto the inclined plate 901, so that the solid impurities can slide onto the first filter screen 902 through the inclined plate 901.

[0046] Embodiment three:

[0047] On the basis of the above-mentioned embodiment 1, since solid impurities will slide into the discharge port 4 through the discharge plate 907 and then be discharged through the discharge port 4, in order to prevent the impurities from falling directly to the ground, the impurities need to be collected, so the following structure is set.

[0048] See also Figure 1-Figure 3 A collection box 3 is also slidably connected to the lower side of the device body 1. The collection box 3 can collect solid impurities, making it convenient to take out the collection box 3 and pour out the solid impurities collected inside it.

[0049] The working principle of the utility model is as follows: first, the staff can install the device and connect the power supply, then pour the solid and liquid waste into the feed hopper 5, and start the drive motor 13. The drive motor 13 can drive the drive shaft 6 to rotate counterclockwise. After the drive shaft 6 rotates counterclockwise, it will drive the driving gear 14 to rotate counterclockwise, and then drive the driven gear 15 to rotate clockwise, and drive the roller shaft 11 to rotate clockwise. At this time, the roller shaft 11 and the drive shaft 6 simultaneously drive the crushing roller 7 to rotate, and the crushing roller 7 can crush the solid impurities, and the crushed solid will flow to the inclined plate 901 together with the liquid;

[0050] Then, the solid and liquid waste will slide onto the first filter screen 902 through the inclined plate 901. At the same time, as the roller shaft 11 rotates clockwise, it will drive the active pulley 908 to rotate, and then drive the driven pulley 910 to rotate through the belt 909, and then drive the movable shaft 903 to rotate. When the movable shaft 903 rotates clockwise, it will drive the scraper plate 904 to rotate, and the scraper plate 904 will drive the fixed impurities accumulated on the first filter screen 902 to move. As the scraper plate 904 continues to rotate, the impurities will be pushed onto the second filter screen 905. At this time, the connecting shaft 906 will drive the scraper plate 904 to rotate, so that the scraper plate 904 pushes the impurities on the second filter screen 905 to move, so that the solid impurities move on the first filter screen 902 and the second filter screen 905 to achieve the purpose of solid-liquid separation. At the same time, the impurities on the second filter screen 905 will be pushed onto the discharge plate 907 by the scraper plate 904, so that the impurities can be discharged through the discharge port 4 and fall into the inside of the collection box 3;

[0051] At the same time, when the driving shaft 6 rotates, it will drive the first sprocket 801 on the outer wall to rotate, and drive another first sprocket 801 to rotate through the first chain 802, and then drive the first rotating shaft 804 to rotate. When the first rotating shaft 804 rotates, it will drive the active bevel gear 810 to rotate, and then drive the driven bevel gear 809 to rotate, and drive the second rotating shaft 807 to rotate, and then drive the fan blades 808 to rotate, so that external air enters the air intake box 803 through the air inlet 805, and then enters the air guide plate 812 through the air guide pipe 811, and is sprayed out through the nozzle 813, so as to blow off the liquid attached to the surface of solid impurities, and at the same time, the liquid attached to the first filter screen 902 and the second filter screen 905 can be blown off, and the filtered liquid will flow to the lower part of the inner part of the device body 1 and be discharged through the drain pipe 2.
