Background
The horizontal screw centrifuge is a settling equipment with horizontal screw discharging and continuous operation. The working principle is that the rotary drum and the spiral pusher rotate at a high speed in the same direction at a certain rotation speed difference, materials are continuously introduced into a material distribution bin of the spiral pusher through a feeding pipe, enter the rotary drum after being accelerated, heavy solid matters are deposited on the wall of the rotary drum to form a slag layer under the action of centrifugal force, and the spiral pusher continuously pushes the deposited solid matters to the conical end of the rotary drum and pushes the solid matters out of the machine through a slag outlet. The feeding mode adopts the feeding of the small end of the spiral pusher, the length of a feeding pipe can be reduced, the breakage of the feeding pipe is avoided, but a large amount of material accumulation is generated when partial materials enter a space between the outer side of the distributing device and a mandrel of the spiral pusher in a countercurrent mode, and therefore the bearing at the small end of the spiral pusher is damaged after the bearing is subjected to material feeding due to sealing failure; meanwhile, a large amount of accumulated materials can cause the spiral pusher to generate eccentric force, increase the operation load and the vibration intensity of the centrifugal machine and influence the service life of equipment.

If the feeding amount exceeds the rated processing amount of the horizontal screw machine, the feeding amount is considered to be too large, the rebounded materials cannot flow back to the material distribution bin along the conical surface too much, the materials exceeding the rated processing amount of the horizontal screw machine flow reversely along the feeding direction over the conical surface, two sections of grooves are arranged on the conical body, second outlets for preventing a small amount of reverse flow materials from being accumulated are symmetrically arranged in the middle of each groove, and the small amount of reverse flow materials can enter the rotary drum from the second outlets.
