    • 专利摘要:
    A feeder apparatus for transferring particulate material and water from a sump outlet to the inlet of a pump is formed in the sump by making a well at the outlet of the sump and placing an impeller in the well. A partition is formed separating the inlet to the feeder from its outlet, the partition having a height equal to or exceeding that of the water level in the sump. The outlet from the sump is connected to a channel which has a continually decreasing cross-sectional area, the terminus of which is connected to the inlet of the pump. A fluid jet can be mounted at the inlet of the feeder for reducing the concentration of particulate fluids at the pump inlet or for fluidizing the particles at the entrance of the pump.

    The invention relates to constructions of thickeners and can be used to separate solid particles suspended in a liquid from a liquid in wastewater treatment processes. 5
    Known thickener ’containing a housing with a bottom and a lifting pump with a suction pipe [1 |.
    In the known thickener, there is no regulation of the sludge density, insufficient thickening is carried out and poor conditions for the removal of sludge take place.
    In order to intensify thickening and improve the output of sludge, the thickener (5 is equipped with a vertical baffle separating the sludge collection and outlet chamber from which the lifting pump is located, a mixing chamber made in the bottom under 20 vertical baffle and connected to the pump suction pipe, and a mixing device located in the rescue chamber.In addition, the mixing device is made in the form of curved blades mounted on a vertical shaft, with the aim of converting the sludge into pseudogap condition, thickened with aeration pipe, 30 • P TB
    the output end of which is installed in the mixing chamber.
    In FIG. 1 shows a proposed thickener, longitudinal section} in FIG. 2 is a section AA of FIG. 1 J in FIG. 3 - section BB of figure 1.
    The thickener consists of a housing 1 with a bottom 2, a lifting pump 3 with a suction pipe 4, vertical. a partition 5, separating from the housing a chamber 6 for collecting and removing sludge, in which the lifting pump 3 is located. In the bottom 2, a mixing chamber 7 is made under the vertical partition 5, connected to the suction pipe 4 of the pump 3. A mixing device 8 is placed in the mixing chamber 7, made in the form of curved blades 9, mounted on a vertical shaft 10. In the mixing chamber 7, the output end of the aeration pipe 11 is installed.
    The thickener works as follows.
    The crushed material enters the housing 1 together with water in the form of a suspension. The crushed material tends to settle and fall out on the bottom 2, where it accumulates on the inclined planes 12 and moves to the chamber 7. The engine 13 rotates the shaft 10 through the coupling 14. The blades 9, rotating, move the crushed material and water inside the chamber 7 and feed to nozzle 4 of the pump 3 *
    A nozzle 11 is supplied aerating liquid or gas.
    The sludge in the fluidized state is sucked off by the pump 3 and through the pipe 15 is discharged from the thickener.
