[0034] The inside of the white water recovery chamber 3 has a structure that is lower in the front and higher in the rear. The small gear 10 and the large gear 14 are meshed. The combination of the right screening roller 12 and the left screening roller 13 is inclined. The horizontal included angle between the combination of the right screening roller 12 and the left screening roller 13 and the white water treatment tank 2 is 10° to 15°. The structure of the inside of the white water recovery chamber 3 being lower in the front and higher in the rear is conducive to better flowing of the white water to the water outlet port 4 and is more conducive to recycling and reuse. The combination of the right screening roller 12 and the left screening roller 13 being inclined is conducive to better rolling of the waste materials into the waste collection box 21 under the influence of their own gravity.

[0035] See Figure 3As shown in the figure, the screening roller support assembly 11 includes a fourth mounting base 1101, a support base 1102, a rotating shaft 1103, a roller 1104 and a card slot 1105. The top of the white water treatment tank 2 is fixedly installed with the fourth mounting base 1101 by bolts. The top of the fourth mounting base 1101 is fixedly installed with the support base 1102. The rotating shaft 1103 is rotatably installed inside the support base 1102. The roller 1104 is fixedly installed on the outer side of the rotating shaft 1103.

The card slot 1105 arranged inside the roller 1104 is adapted to the snap ring 16 on the screening roller, which greatly improves the stability of the screening roller, has high practicability and stronger stability.

[0036] The outer filter screen 17 and the inner filter screen 18 have the same structure. The horizontal center lines of the outer filter screen 17 and the inner filter screen 18 are on the same horizontal line. There are two layers of filter screens, which can better filter out impurities, greatly improve the working efficiency, and make the collected white water purer and not easily block the water outlet 4.

[0037] The water inlet 7 is located inside the inner filter screen 18. The cross section of the water inlet 7 is in an "L" shape structure. The water inlet 7 and the inner filter screen 18 do not contact each other, which is beneficial for the white water to better enter the filter screen. And the fact that the water inlet 7 and the inner filter screen 18 do not contact each other improves the working efficiency and speeds up the working process.

[0038] See Figure 7 As shown in the figure, the outer frame assembly 19 includes a first ring 1901, a second ring 1902, a third ring 1903 and a connecting rod 1904. The right side of the left screening roller 13 is fixedly installed with the first ring 1901. The left side of the right screening roller 12 is fixedly installed with the third ring 1903. The second ring 1902 is arranged between the first ring 1901 and the third ring 1903. The connecting rods 1904 are fixedly installed between the first ring 1901, the second ring 1902 and the third ring 1903 by bolts. The centers of the first ring 1901, the second ring 1902 and the third ring 1903 are on the same horizontal line. This setting that the centers are on the same horizontal line is more conducive to ensuring the better installation of the filter screen on the one hand, and on the other hand, it is better to make the whole combination rotate through the connecting rod 1904, which is beneficial for collecting and recycling white water and has a better effect of removing impurities.

[0039] The upper half of the shielding cover 24 is in a "U" shape structure, and the lower half of the shielding cover 24 is in a "︺" shape structure. The lower part of the shielding cover 24 extends into the white water treatment tank 2, which can better completely wrap the filter screen and ensure that the white water is thrown out due to the centrifugal force during the rotation process, greatly improving the stability during collection.

[0040] During use, the snap rings 16 on the outer sides of the left screening roller 13 and the right screening roller 12 are both engaged with the clamping grooves 1105 on the inner part of the roller 1104 in the screening roller support assembly 11. The outer skeleton assembly 19 and the inner skeleton assembly 20 are installed between the left screening roller 13 and the right screening roller 12. The outer filter screen 17 and the inner filter screen 18 are respectively installed on the outer skeleton assembly 19 and the inner skeleton assembly 20. At this time, the material receiving plate 22 on the top of the waste collection box 21 is connected to the installation groove 15 inside the left side of the left screening roller 13. After the installation is completed, the shielding cover 24 is fixed to the top of the installation base three 23. The motor 9 is started to drive the small gear 10 to rotate. The rotation of the small gear 10 drives the meshing-connected large gear 14 to rotate, thereby driving the right screening roller 12 to rotate. The rotation of the right screening roller 12 drives the left screening roller 13 to rotate through the outer skeleton assembly 19 and the inner skeleton assembly 20. At this time, the combination of the right screening roller 12 and the left screening roller 13 rotates.

[0041] In the above process, the water inlet 7 is connected to introduce untreated white water. The untreated white water flows into the inner filter screen 18 through the water inlet 7. Under the action of the inner and outer two-layer filter screens, the waste and the white water are separated. At the same time, due to the inclined setting of the combination of the right screening roller 12 and the left screening roller 13, the waste rolls into the waste collection box 21 under the influence of its own gravity. The material receiving plate 22 on the top of the waste collection box 21 is connected to the installation groove 15 inside the left side of the left screening roller 13, so that the waste can roll into the waste collection box 21 better. And the separated white water flows to the white water recovery chamber 3 through the inner filter screen 18 and the outer filter screen 17. The inside of the white water recovery chamber 3 has a structure with a lower front and a higher rear, so that the treated white water can flow to the water outlet 4 better, which can effectively recycle and collect the white water, is more practical and convenient to use.

[0042] The above shows and describes the basic principle of the present invention. The above is only the preferred embodiment of the present invention and is not used to limit the present invention. The descriptions in the above embodiments and the specification only illustrate the principle of the present invention. Without departing from the scope of the present invention, any modifications, equivalent replacements and improvements made within the spirit and scope of the present invention shall be included in the protection scope of the present invention.
