    专利说明:

    The invention relates to devices for separating solids and liquids by centrifugal forces and can be used in the chemical industry, as well as in wastewater treatment techniques.
    The purpose of the invention is to increase efficiency and simplify the design.
    Figure 1 is a schematic representation of the proposed device for separating solids and liquids, the cross section; figure 2 - view aa in figure 1.
    A device for separating solids and liquids includes a primary body 1, a nipple 2 supplying raw materials a pipe 3 for draining a liquid, a pipe
    4d solids removal, conclusion
    5 small particles, cyclones 6 with vertically located bodies and diverting devices 8 connected to the body 1 through an annular inlet device 7. In the upper part of the body 1 there is a receiving chamber
    9 with a bottom wall 10 in which the upper sections 11 of the cylindrical elements 12 are disposed, the upper wall 13, with the upper sections 14 of the cylindrical devices 15 for removing the liquid installed therein. It is preferable that both the bottom wall 10 and the top 13 in order to increase their strength are curved and the vertical distance between them is the same at any point. In this case, the length of all the cylindrical devices 15 for draining the liquid was the same, as a result of which the difference in pressure was avoided.

    elements, which could lead to the effect of pulsation of a liquid and a solid substance between different elements. In the lower sections of the cylindrical elements I2 and cyclones 6} in which a mixture of solids and liquids is attached to a helical motion, stabilizing vortices of devices (not shown) can be located.
    The primary body I is located inside the secondary body 16 and has a solid substance collector 17 and a liquid collector 18 in the lower part, solid conclusions 19 are located in the lower part of cyclones 6, and in the upper part of the cylindrical elements 12 between the walls of the elements and the fixtures 15 for removal of liquid devices 20 are installed to create a vortex motion inside the elements 12. Connection of the housing I with the terminal
    5 is carried out through the conical part of the primary body 21, and tube 3 through the upper section of the apparatus 22. Entering the initial mixture into the cyclone
    6 is carried out through a power supply installed tangentially to their casing.
    Device 23.
    The ratio of length to diameter of cylindrical elements 12 is recommended to be selected in the range of 1-10, preferably 2-5. The ratio of the diameters of the cylindrical elements 12 and the cylindrical devices 15 for drainage, respectively, is 1.2-4, preferably 1.5-2.5. The diameter of the cylindrical element is recommended to take, respectively, 0.05-1 m, preferably 0.1-0.8 m, the diameter of cyclones 6 is usually larger due to the larger amount of solids in the liquid entering the first stage, respectively 0.5-8 m, preferably 1 -6 m
    The initial mixture is fed through pipe 2 into the housing 16 under pressure and enters the cyclone 6 through the feeding devices 23. Due to the tangential arrangement of the feeding devices 23 relative to the cyclones 6, the incoming mixture is twisted and in the cyclone 6 the primary separation of the mixture to the condensed product discharged through Conclusion 19 of the solid substance and the clarified liquid entering through the diverting devices 8 and the annular inlet device 7 connected to them, into the receiving chamber 9. Continuing the movement, the clarified liquid enters black The upper sections 11 into the cylindrical elements 12, where, due to the presence of the device 20 for creating a whirlwind, are also twisted. Fine particles are thrown to the walls of the elements 12, lowered over them and enter the solid collector 17, from which they are discharged through outlet 5 The completely purified liquid through the cylindrical devices 15 for draining the liquid enters the collector 18, from where it is removed through the pipe 3 for draining the liquid.
    Thus, the proposed device allows a significant increase in the efficiency of separation of solids and liquids due to the presence of
