[0050] Specifically, the inner wall of the sealing cover 42 and the outer wall of the rotating shaft 7 are sealed by a sealing ring or a packing seal.

[0051] Specifically, the limiting member 81 is a locking screw.

[0052] Preferably, the shaft sleeve 41 is provided with an arc-shaped limiting notch 43, and the two end surfaces of the arc-shaped limiting notch 43 along the circumferential direction are respectively a closed limiting surface 44 and an open limiting surface 45; specifically, in the present application, the arc-shaped limiting notch 43 is provided at the position corresponding to the shaft sleeve 41 and the arc-shaped limiting plate 61, and the two ends of the shaft sleeve 41 are still complete circumferential structures, so as to maintain the guidance of the rotating shaft 7 and the limiting in the radial direction;

[0053] An arc-shaped limit plate 61 is fixedly disposed at the bottom end of the liquid receiving hopper 6, and the rotating shaft 7 is coaxially fixedly disposed on the radial inner side of the arc-shaped limit plate 61;

[0061] Embodiment 2:

[0062] A solid-liquid separation device comprises the solid phase discharge port liquid receiving device of embodiment 1.

[0063] Under normal conditions, the liquid receiving hopper 6 is in a closed state, and the liquid receiving window 4 on the liquid discharge side wall 3 is closed by the liquid receiving hopper 6 to prevent the solid phase material from entering the liquid storage box 5. When cleaning the solid-liquid separation device, loosen the locking screw on the handle 8, turn the handle 8 to drive the liquid receiving hopper 6 to flip to the open state, and then tighten the locking screw; then start the spray cleaning mechanism inside the solid-liquid separation device to achieve spray cleaning.

When the solid-liquid separation device is finished cleaning and the cleaning water no longer flows down, turn the handle 8 in the opposite direction to reset the liquid receiving hopper 6 to the closed state and lock it. Afterwards, the cleaning liquid is sprayed through the inner cleaning pipe 52 above the liquid storage box 5 to clean the inside of the liquid storage box 5.

[0064] The provision of a liquid receiving device at the solid phase discharge port in the solid-liquid separation device can effectively reduce the probability of cleaning water entering the solid phase outlet, thereby reducing the impact on the moisture content of the solid phase, especially for continuous production process conditions, to avoid cleaning water entering the downstream equipment of the solid-liquid separation device, such as dryers, and causing operating failures; it can save the cost of manually opening the cover to clean the block materials formed inside the equipment after the cleaning water enters the solid phase outlet and mixes with the solid phase, thereby ensuring the continuous and stable operation of the equipment.

[0065] The solid phase discharge port receiving device has a self-cleaning function through the setting of the internal cleaning pipe 52, which can prevent the solid phase precipitation mixed in the cleaning water of the solid-liquid separation device from sticking to the wall and clogging, ensuring that the inside of the liquid receiving device is always kept clean, and there is no need to stop the machine separately to clean the materials therein during use.

[0066] Although the above describes the specific implementation mode of the present invention in conjunction with the accompanying drawings, it is not a limitation of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art on the basis of the technical solution of the present invention without creative work are still within the protection scope of the present invention.
