Abstract

The invention relates to agriculture and provides an increase in the efficiency of the separation of liquid manure into fractions. A perforated cylinder 2 is installed in a cylindrical perforated drive drum 1 by means of elastic connections 6. The elastic connection 6 is made in the form of helical conical springs. The larger base of the spring is fixed on the drum 1. The springs are located in radial planes. The springs of each plane are offset circumferentially relative to the springs of the adjacent plane. The stiffness of the springs of one plane is made the same, and in the direction of the nozzle 3 for feeding manure, the stiffness of the springs increases. Manure from the nozzle 3 enters the cylinder 2. The liquid fraction through the perforations of the cylinder 2 enters the inner surface of the drum 1 and is finally clarified. The liquid fraction from the drum enters the collector 7, and the solid fraction goes to the conveyor 8. With a uniform rotation of the drum 1, the cylinder rotates with pulsating oscillatory movements due to the displacement of the center of mass. The rise and discharge of the solid fraction occurs intermittently, which ensures the vibrational oscillations of cylinder 2. 3 Cp f-ly, 4 ill. § (L: l e

Description

The invention relates to devices for clarifying contaminated liquids and can be used in agriculture for the separation of liquid manure into solid and liquid fractions.

The purpose of the invention is to increase the separation efficiency. In FIG. 1 shows a device for separating slurry, a general view; FIG. 2 shows a section A-A in FIG. 1, FIG. 3 shows a section BB in FIG. one; in Fig. - 4 - the same, option.

A device for dividing slurry into fractions contains an inclined perforated drum 1 associated with a drive mechanism (not shown) with perforated cylinder 2 perforated inside it. At one end of drum 1, a manure supply pipe 3 is inserted into the cavity of cylinder 2. The opposite ends of the drum 1 and cylinder 2 are discharge ports 4 and 5 responsibly. The cylinder 2 is attached to the body of the drum 1 by means of elastic links 6, for example conical coil springs, the larger base of which is attached to the drum 1. The springs are located in several radial planes. In this case, the springs located in the same radial plane are displaced along the circumference relative to the springs located in the adjacent radial plane, and are made in the same radial diameter of the drum with the same rigidity, and the length of the drum is variable. At the entrance to the drum in the area of the manure supply nozzle, the stiffness of the springs is greater than its output. Under the action of the weight of the cylinder 2 and the manure mass, the lower springs are compressed and the upper ones are stretched, as a result of which the geometrical axis of the cylinder 2 is located below the axis of the drum 1. Under the drum 1 there is a collection 7 of the liquid fraction, and at the bottom end of the drum transporter. The springs can be made of a strip material (Fig. 4).

The device works as follows.

Liquid manure through pipe 3 is fed into the cavity of the perforated cylinder 2. When the drum 1 rotates, torque is transmitted through elastic links 6 to cylinder 2. Liquid fraction

manure with small particles passes through the cylinder bores and enters the inner perforated surface of the drum 1. As the fluid moves along the drum on a slope, its final clarification occurs. The liquid enters the collector 7, and the solid fraction from cylinder 2 and drum .1 is transported to conveyor 8. During operation, the device at nozzle 3 in cylinder 2 has more (by weight) manure, and at its output end less. But since the spring stiffness decreases at the drum inlet to the drum outlet, the geometric axis of the cylinder is located lower and approximately parallel to the axis of the drum. With a uniform rotation of the drum, the cylinder rotates with a pulsating oscillator. due to unbalance and displacement of the center of mass, as well as due to the fact that the cylinder is elastically fixed to the drum at individual points located offset in the radial planes and the lifting and dumping of the solid fraction from the surface of the drum is not intermittently in the form of individual lumps. Thus, vibratory oscillation of the cylinder is provided.
