Description

The invention relates to equipment for cleaning liquids from mechanical impurities and can be used in wastewater treatment, in agricultural production, etc.

The aim of the invention is to increase the efficiency of cleaning fluid with soils that are prone to sticking.

FIG. 1 shows a diagram of the device, a general view; in fig. 2 is a section A-A in FIG. one; in fig. 3 is a section BB in FIG. one; in fig. 4 shows a section B-B in FIG. one.

The device comprises a screened filter element in the form of a truncated cone 1 with a drive 2 and a screw blade 3, a reservoir 4 for the filtrate and a reservoir 5 for collecting contaminants. The filter element 1 is mounted for rotation around its axis on supports 6 and 7

The actuator 2 is made in the form of tanks 8 attached to the inner surface of a larger base of the filter element (Fig. 2), uniformly placed around the perimeter, the holes in which are located in the direction opposite to the direction of rotation of the filter element, the inlet 9 with the bent end 10 placed above the open part of the containers 8. The screw blade 3 is installed in the form of a screw 11 along the central axis of the filter element with a gap between the outer edges of the turns and the inner surface of the filter element and the top Flax to its wall bracket 12, by the greater base of the filter element.

about

There is a screw auger 11. Under the screw 3 there is a transport tray 14 (fig. 3 and 4) for contamination, which is attached on one side to the wall of the container 5 by means of a bracket 15, the other end of the tray is not fixed and is on the weight. On the outer surface of the outlet pipe 13, a crown of teeth 16 (Fig. 4) is attached, which is in contact with the stop 17. The stop 17 is attached on the bracket 18 to the wall of the container 5. One side of each tooth 16 is inclined to the generator of the cone, and the other is under the straight angle to it, and the stop 17 is made with a bevel corresponding to the inclined side of the tooth 16,

The device works as follows.

The initial fluid through the inlet 9 and the bent end 10 is poured into the container 8 located at the level of the axis of rotation of the filter element 1. The container 8 filled with liquid forces the filter element to rotate the filter element, bringing the next container under the bent end 10 after being filled with liquid, it is lowered, while the previous one reaches the lowest point and is emptied of liquid. Thus, due to the filling and draining of the liquid in the tank 8 and from them the filter element 1 comes into rotational motion. Flowing out of the containers 8, the liquid flows onto the mesh filter element 1 and flows into the tank 4 to collect the filtrate, leaving on the inner surface of the filtering element of the soil, the dimensions of which are larger than the mesh cells. The contaminants remaining on this surface, as the filter element rotates, rise by adhering to the surface to the top point on the surface of the filter element. As the filtering element is shaken by rotating the teeth 16 from the stop 17 as it rotates, when the upper position is reached, the contaminants are torn off and fall into the transport tray 14, to which the shaking forces are also partially transferred, under the influence of which the contaminants are mixed into the central part of the tray and the screw 3 are removed to the outlet nozzle 13. Due to

Since the tray 14 is immobile due to its fastening on the bracket 15 to the wall of the container 5, and the screw 3 rotates, as it is attached by the bracket 12 to the rotating filter element 1, then the contaminants prone to sticking are reliably transported. Making the second ends of the chute 14 and the screw 3 free (loose) ensures that the auger rotates unhindered relative to the transport chute.

The implementation of the screw with a loose lower end (console fastening) when it collides with the tray provides

intense oscillation of the auger, which contributes to the cleaning of its turns from sticking sediment.

Thus, the proposed design allows not only forcibly

to move the sediment to the outlet part by the screw, but at the same time with the in-brush cleaning of the surface of the filter element, side parts of the tray, turns of the screw auger from contamination.
