Abstract

1. A BULKER, containing a cylindrical housing, a mechanism for unloading a condensed product with rippers in the outlet neck, a recessed loading device consisting of a cylindrical upper and conical lower parts and having a ring at the bottom base and a baffle disk of the same diameter, characterized in that the purpose of increasing the productivity of the apparatus, the degree of clarification of the suspension, and increasing the reliability of unloading the condensed product, the loading device is equipped with a cylindrical receiver with a receiving cup and a partition placed in it, and with a pipe connecting the receiver to the loading device, the receiving cup is located below the overflow level in the apparatus, the partition is placed along the receiver diameter from its lower base to the overflow level, the pipe connecting the receiver and the loading device , is set at an angle to the horizontal, and the upper parts of the cylindrical receiver and the loading device are provided with snapshots (for the pipes with a tangential water supply). 2. A thickener according to claim 1, wherein the loading device is provided with arcuate partitions placed between the ring and the baffle plate, consumed from the center, and the rippers in the outlet neck are wedge-shaped and angled to the wall of the neck.

Description

1 .1 The invention relates to the field of thickening and clarifying suspensions, namely, thickeners, intended to thicken sludge and clarify slurry waters, and can be used in the coal, mining, chemical g and other industries. The purpose of the invention is to increase the productivity of the apparatus, the degree of condensation of the suspension and increase the reliability of the discharge of the condensed product. FIG. 1 shows a thickener, a cut; in fig. 2 shows section A-A in FIG. one; in fig. 3 - section BB in figure 1 | figure 4 - boot device, the cut; in fig. 5 - receiving funnel, incision; in fig. 6 same, top view. The thickener contains a cylindrical housing 1, along the axis of which a recessed loading device is arranged, consisting of a cylindrical part 2, a conical part 3 and a ring 4. At the top of the cylindrical part 2 there is a tangential nozzle 5 for supplying 1USD. Below the ring 4 of the loading device, there is a baffle disk 6, between the ring 4 and the disk 6 there are placed arcuate partitions 7. Inside the cylindrical receiver 8 there is a receiving cup 9 located below the overflow level in the apparatus, and a partition 10 placed along its diameter bottom base to overflow level. The receiver 8 in its upper part has tangential nozzles 11 for introducing water. In the throat, there are wedge-shaped rippers 12 located 2 at an angle to the wall of the neck and fixed on the shaft of the strokes 13 with the drive 14, Receiver 8 is connected to the cylindrical part 2 of the loading device by the inclined pipe 15. The thickener works as follows. The suspension is fed into the thickener 1 with polymer flocculant additives along the inclined pipe 15 from the receiver 8, into which it is poured from the receiving cup 9. Air bubbles and foam, which is destroyed by water, flow from the suspension underneath. arriving tangentially through the pipes 11. To prevent the liquid from twisting in the receiver 8, a partition 10 is placed above the glass 9, contributing to a more calm overflow, which means better air release. The suspension with the remaining small air bubbles enters through the inclined pipe 15 into the central part 2 of the loading device. The foam released there is destroyed at the top of the cylindrical part 2 by water supplied tangentially through the nozzle 5, and the suspension enters the conical part 3 of the loading device and then through the gap between the ring 4 and the baffle plate 6 is introduced into the thickener deposition zone in the horizontal plane. The arcuate partitions 7 impart a horizontal rotation to the suspensions. The thickened product is moved by the strokes 13 to the outlet neck, in which the wedge-shaped rippers 12 rotate from the actuator 14, drastically reducing the likelihood of clogging of the hole with sediment.
