MD3748G2 - Liquid disperser - Google Patents

Abstract

The invention relates to plants for homogenization, emulsification and dispersion of liquid mixtures and can be used in the food, chemical and petroleum-refining industry.The liquid disperser comprises a cylindrical body (1) with a dispersion chamber D, wherein it is installed a driving shaft (6) with rotor (3), made in the form of disk with cavitators (5), at the same time on the opposite part, on the lateral wall of the body (1) there are also fixed cavitators, and liquid admission (27) and outlet (28) branches. Novelty consists in that the disperser is additionally equipped with suction A, pressure B and reception C chambers, in the suction chamber A it is placed a centrifugal pump (2), consisting of a stator (8) and an impeller (9), as well as is provided with a dividing wall (7) of the reception chamber C and of the dispersion chamber D. The stator (8) of the centrifugal pump (2) is made of the front 13) and back (14) disks, between which it is placed a ring in the form of truncated cone with rectangular holes (12). Between the stator disks it is placed the impeller (9) fixed on the driving shaft (6), made of the front and back disks, the edges of which are joined by a ring, repeating the form of the stator's ring, wherein there are made rectangular holes. The back wall (11) of the stator (8) is equipped with a flange (17), wherein it is installed a spring (19), and pins (18). In the upper part of the back wall (11) of the stator (8) it is made a hole (20) for liquid outlet from the pressure chamber B, made in the stator, into the reception chamber C. The dividing wall (7) of the reception chamber C and of the dispersion chamber D, fixed onto the driving shaft (6), is hermetically sealed at the periphery by a seal ring and is equipped with a flange (22), entering into the flange (17) of the back wall (11) of the stator (8), hermetically sealed by a seal ring (23). Into the dividing wall (7) there are made two recesses, wherein there are installed the pins (18). In the back part of the dividing wall (7) it is made a flange (26), wherein there are made holes (24) identical with the holes (25) made into the rotor (3) of the dispersion chamber D.
