Description

00 00 WITH

The invention relates to agriculture, in particular for separating the solid phase from suspensions, for example, in classifying liquid manure in wastewater treatment plants of livestock breeding complexes, and can be used to classify sludge and pulp.

The purpose of the invention is to improve the quality of classification by increasing the uniformity of the mixture feed to the sieve while reducing the overall dimensions of the JO device by varying the mixture head.

FIG. 1 shows the device, a general view; in fig. 2 - part of the receiving tank

SI overflow threshold 9 across the entire width of the sieve 3.

The overflow threshold 9 with the lower edge 10 covers part of the sieve 3. The sieve 3 is located obliquely at an angle, ensuring that they move the liquid manure under the action of gravity forces. Under the sieve 3 is a tray 4 for the filtrate. In the lower part of the pallet 4 is installed a pipe 11 for draining the filtrate.

The device works as follows.

Liquid manure, supplied under pressure (from the pump) through the inlet nozzle 5, enters the lower part of the receiving tank 2 and through the openings 7 of the „„ „city 6 and free spaces between
