Description

A convenient and durable screw pusher

technical field

The utility model relates to the field of concentrators, in particular to a screw pusher.

Background technique

The concentrator is a settling equipment with screw discharge and continuous operation. Its working principle is that the drum and the screw feeder rotate at a high speed in the same direction at a certain differential speed, and the material is continuously introduced into the screw feeder from the feed port. Entering the drum, under the action of the centrifugal force field, the heavier solids are deposited on the wall of the drum to form a sediment layer, and the screw pusher continuously pushes the deposited solids to the cone end of the drum, and passes through the slag outlet. When discharged out of the machine, the lighter liquid phase forms an inner liquid ring, continuously overflows the drum from the overflow port at the large end of the drum, and is discharged out of the machine through the liquid discharge port.

The interior of the central shaft of the screw propeller of the existing centrifugal concentrator is a welded structure, and the welding material and the interior of the central shaft of the spiral propeller together form a distribution bin for relatively uniform distribution of materials. Since the inside of the central shaft of the screw feeder is a welded structure, when the material contains particles with relatively high hardness, the material will wash away the welding material and the inner wall of the central shaft of the screw feeder, which is very easy to cause wear and tear, resulting in the welding material and the screw pusher. The surface of the inner wall of the central shaft of the feeder is washed to form grooves and pits, which will reduce the strength of the screw feeder, destroy the dynamic balance, and aggravate the vibration of the equipment. If the material passes through the welding material, it will damage the bearing system and even cause the entire screw feeder scrapped.

In the utility model, the distributor can be made of metal material or ABS plastic, wherein the distributor made of ABS plastic is not only stronger than the distributor made of metal, but also lighter in weight.

Compared with the prior art, the beneficial effects of the utility model are:

The utility model installs a straight cylindrical material distributor inside the central shaft of the screw pusher through screws, which can prevent the material from directly washing the inner wall of the central shaft of the screw pusher, reduce the wear of the screw pusher, and make it durable. After the distributor is worn out, it can be disassembled and replaced separately without replacing the whole screw pusher, which is very convenient to use.
