Description

The invention relates to purification, wastewater, in particular, devices for separating suspensions and compacting sludge, and can be used to compact sludge in industrial enterprises, such as metallurgical, petrochemical, pulp and paper, etc.

The purpose of the invention is to increase productivity due to the reduction of the production cycle and the production of low residual sludge.

The drawing shows a sludge compactor, longitudinal section.

The device includes a body 1 with a conical bottom, a supply pipe 25, a sealing washer 3, an elastic valve 4, for example, of rubber with a diameter greater than the diameter of the body, a rod 5, a pipe 6 for sludge drainage, an extension 7 in a case made in the form of two cones A large base, a collection of 8 clarified water with a discharge pipe 9, a shut-off valve 10 and check valves 11.

The device works as follows

The housing 1 is filled with the treated suspension through the inlet nozzle 2, the sealing washer 3 with the valve 4 fixed to it with the help of the rod 5 lifting it to the uppermost position, and the valve 4 sealing the gap between the sealing washer 3 and the housing 1. ( The outer diameter of the valve 4 is significantly larger than the internal diameter of the housing. Tightness is created due to the tight fit of the valve face to the inner surface of the housing.

When the puck moves downwards, an overpressure is created in the housing, and additional valve pressure 4 against the walls of the housing 1, 5 occurs. Under the action of overpressure, the air-ear, which is in the pores of the suspension, is compressed, the pores are filled with water and the most increases the mass of the substance, which increases its deposition rate. A decrease in the volume of a substance due to pressure also contributes to an increase in the rate of its settling and a decrease in the residual moisture of the sediment.

The solid phase is assembled in the conical part of the device and viewed out. through the discharge nozzle 6. When after: blowing, moving downwards, the washer goes through expansion 7, while valve 4 is under pressure and due to the elasticity of the material turns in the opposite direction. With further movement, the washers compacting down the washers - a breakthrough of the liquid phase takes place between the housing 1 and the valve 4, with continued removal of the compacted sludge. Upon reaching the lowest position, the sealing washer rises. When this occurs, the initial treated suspension through the inlet nozzle 2 simultaneously occurs by moving the liquid phase to the collector 8, from which it is removed through the outlet nozzle 9. The passage through the expanded: 7, the valve 4 turns back to the supporting surface

The process is repeated with the reciprocating movement of the sealing washer.

Shut-off valves 10 and return valves pap. 11. ensure that the pressure in the housing is maintained at pre-45 parts of 3–10 grams, the cycle of suction of the initial suspension and release of compacted sediment and clarified water
