SU1447406A1 - Apparatus for purification of lake salt - Google Patents

Abstract

The invention relates to the purification of lake salt by washing it from water-insoluble residue, salts, magnesium, and allows for an increase in the efficiency of the purification process due to the turbulization of the two-phase flow. The vertical cylindrical body 1 is partitioned along the height of a truncated conical plate (T) 2. In the upper half of T 2, they are perforated with an apex of 3 and are placed in the lower one. concentric rows of fingers (P) 4. Shaft 5 with disks 6 with corrugations and conical nozzles 7 is placed in housing 1. Each of nozzles 7 is made up of two base-conjugated parts. The lower part is made conical with concentric rows of P 9 located on it and installed with a gap above each T 2. Salt particles fall between movable P 9 and fixed P 4 and experience impacts between themselves and between P 4 and 9, then arrive on the disk 6. Under the action of centrifugal force, the particles move to the walls of the housing 1 and are cleaned on the corrugated surface of the disk 6. 1 Cpf-type, 2 Il. S (l

The invention relates to the purification of lake salt by removing it from water-insoluble residue, magnesium salts, and can be used in the salt industry to enrich lake salt.

The purpose of the invention is to increase the efficiency of the cleaning process due to the turbulence of the two-phase flow.

1 shows a general view of the device; on - section aa in figure 1.

The device consists of a vertical cylindrical body 1, partitioned in height by truncated conical plates 2, perforated holes 3 in the upper half, and 2-3 pins of fingers 4, the shaft 5 with disks 6 and conical nozzles 7 are located in the lower half. 8 around the circumference of the cone nozzle is provided with rows of fingers 9. For loading and unloading salt, there are loading U and unloading 11 devices, and for entering the washing liquid apparatus, the nozzle 12 and its removal are the nozzle 13,

The device works as follows.

 The rinsing liquid is supplied to the pipe 12, as the apparatus is filled, the drive shaft 5 is turned on, and then the salt to be cleaned is fed through the loading device 10.

Salt particles, between moving fingers 9 of conical nozzle 7 and non-unfamiliar fingers 4, conical plates 2 experience both impacts between themselves and between fingers, while changing the direction of movement several times, after

As the particles sink into the center of the disk, under the action of centrifugal force they begin to move

along the disk (in a spiral) to the walls of the housing 1 and at the same time they are cleaned of impurities on the corrugated surface. This process is then repeated several times. next steps x
