Abstract

Usage: for separation of liquid heterogeneous systems in the field of centrifugal forces. Essence: in a hydrocyclone comprising a cylindrical conical body (1) and a cylindrical conical insert (3) located inside it, the taper angles of the outer surface of the insert and the working surface of the body are made with a ratio of 1: 1.4-1: 2. In the conical part of the insert (3), tangential slit holes (5) are made, facing the direction of movement of the initial flow, and inside the drain pipe (4) of the insert (3) there is a conical cup (7) with recesses (11) on the side, surface and adjacent flat cut-offs (8) located in the direction of flow to the recesses of the glass. Due to the difference in taper angles of the insert and the housing, particle acceleration increases. In addition, further separation is carried out inside the drain pipe (4) of the insert (3). 1 s.p. f-ly, 3 ill.

Description

The invention relates to devices for separating liquid heterogeneous systems in the field of centrifugal forces and can be used in the food industry, in particular when clarifying grape must, beer, etc., and in a number of other industries.

The aim of the invention is to reduce energy consumption and simplify the design of the known hydrocyclone while maintaining the cleaning efficiency of the initial suspension.

Figure 1 shows a hydrocyclone made according to the invention, a General view; figure 2 is a section aa in figure 1; in Fig.3 - conical glass 7 in Fig.1.

The hydrocyclone contains a cylindrical conical housing 1 with a tangentially installed inlet pipe 2, a cylindrical conical insert 3 mounted coaxially inside the housing and secured from the side of the cylindrical part to the housing 1. Moreover, the taper angles of the cylindrical conical insert and the working surface of the housing are made in the ratio 1: 1.4- 1: 2 and. are respectively 22 and 30 °. - 22 and 44 °. A drain pipe 4 is made along the axis of the cylinder-conical insert 3, the lower part of which is conical. In the conical part of the cylindrical conical insert 3, tangential slotted holes 5 are made, facing the direction of motion of the initial flow. From the top of the conical part of the housing 1, a sand pipe 6 is installed. Inside the drain pipe 4 there is a conical glass 7 with recesses 11 on the side surface and flat cut-offs 8. located in the direction of flow and adjacent to the recesses 11 of the conical glass

7. The sand pipe 9 of the cylinder-conical insert 3 is located concentrically in the sand pipe 6 of the housing 1.

The hydrocyclone works as follows.

The initial suspension under pressure enters through a tangentially installed inlet pipe 2 into the annular cavity formed by the lateral surfaces of the coaxially arranged cylindrical-conical insert 3 and the cylindrical-conical body 1, and acquires a rotational spiral-like motion around the insert 3. In this case, under the action of centrifugal forces, heavier particles discarded to the inner walls of the housing 1, moved to the top of the cone and removed through the sand pipe 6. Due to the fact that the taper angles of the cylindrical the inserts and the working surface of the body are made with a ratio of 1: 1.4-1: 2, the cross section of the annular cavity at the top of the conical part of the hydrocyclone decreases sharply, and the cleaned liquid containing fine particles passes through the tangential slots - 5 into the drain pipe 4 and acquires sunrise general rotational motion. Since the radius of rotation of the stream is sharply reduced, the particle acceleration is greatly increased. In this case, fine particles under the action of centrifugal forces are thrown to the walls of the drain pipe 4 and, under the action of gravity, slide to the conical glass 7. Then, through vertical slots 10, formed with an inner pen 0

The main features of the drain pipe 4 and flat cut-offs 8 adjacent to the recesses 11 of the conical cup 7 fall into the sand pipe 9 and are removed from the hydrocyclone.

Thus, the invention saves energy by 15-20% and simplifies the design of the known hydrocyclone, while maintaining high separation efficiency.
