Description

(54) SEPARATOR

one

The invention relates to a technique for separating ice from the solutions from which it is formed, and can be used in food concentrating plants and desalination plants.

Known ice separator containing a cylindrical body, a piston, with located on it inlet and exhaust valves, a conical chamber with partitions, a knife device located on the drive shaft 1.

However, the known separator has a low productivity due to the small living cross section of the through-holes for discharging ice-water pulp and low separation capacity due to the fact that squeezing the ice-mortar pulp occurs without washing, increasing the loss of ice concentrate.

The purpose of the invention is to increase the separator performance, its reliability and the degree of separation.

This goal is achieved by the fact that the knife device is made in the form of a cone, the base of which is connected to the end surface of the housing, the partition is made spiral, and the surface of the knife device is perforated.

The separator is equipped with a conical frame with a grid and ribs mounted on the piston, as well as ribs located on the conical part of the body.

In addition, the spiral partition in the conical chamber is made of elastic, antifriction and hydrophobic material, and the ribs of the conical frame are installed above the grid of the frame.

Claims (6)

The separator consists of a cylinder 1 with an expanding taper in the upper part and protruding in the same area in the cylinder 1 to its forming ribs 2, extending upwards. A rotating cone head 3 is installed on the cylinder 1 with slots 4 for the passage of ice and cutting blades 5 embedded in these slots 4 so that the cutting edge protrudes beyond the inner surface of the head 3. The latter is made, for example, porous or with holes 6 , overlaid with the bottom of grid 7, do not penetrate the ice crystals. The head 3 is driven through a drive shaft 8, which is fitted with a gland 9. A cone chamber 10 is installed over the rotating head 3 on the mounting flange of the cylinder 1 with a flush water inlet nozzle 11 and a freshwater pulp outlet 12. Inside the conical chamber 10 a spiral partition 13 is installed, made of an elastic, antifriction and hydrophobic material, for example a fluoroplastic. The spiral partition 13 has an increasing from the inlet 11 to the outlet 12 of the spiral pin. A movable piston 14 is moved inside cylinder 1 with a conical frame 15 installed on it (or a truncated cone of porous material), between the ribs 16 of which is a mesh 17, which protects against the ingress of ice crystals, self-acting exhaust valves 18 installed on the horizontal surface of the piston 14 The piston rod 19 of the piston 14 has an internal channel 20 through which the ice-slurry flows to the self-acting inlet valve 21 installed in the upper part of the conical frame 15. When the separator is operating during the piston stroke 14 Downward, an ice-mortar pulveriver enters through channel 20 of rod 19 to self-acting inlet valve 21. By the action of the pressure difference of the pulp in channel 20 of rod 19 and cylinder 1 of the separator, valve 21 opens and passes the pulp into the cylinder 1. With piston 14 running upwards the inlet valve 21 closes and the process of compressing the ice-slurry pulp begins. In this case, the concentrate, mixed with a certain amount of wash water passing through the upper layers of ice, is filtered on the grid 17 of the conical frame 15 and through the self-acting exhaust valves 18 is discharged from the separator cylinder 1. Pressed by the piston 14 and washed with water flowing through the porous head 3 (or the holes 6 in the head, covered with mesh 7), the ice crystals are cut by the rotating blades 5 and through the slits 4 are pushed into the flow of wash water passing through the channel formed by the conical chamber 10 and a spiral partition 13 in it. The pulp formed from the water-ice is removed through the nozzle 12 from the separator. The supply of water for washing and transporting ice is carried out through the nozzle 11. Making the knife device in the form of a cone leads to an increase in the proportion of the living section of the through-holes for draining the ice-water slurry, without changing the diameter of the cylindrical part of the casing, and thereby increases specific performance separator. Uniform irrigation of ice crystals with wash water through a water-permeable conical head, carried out simultaneously with a cut of these crystals, contributes to an increase in the degree of separation of the original pulp. Installing a ribbed cone with a grid of the frame on the piston improves the reliability of the exhaust valves due to the absence of ice crystals in the burned out concentrate and provides the same hydraulic resistance of the ice mass to the flush liquid and the cooled concentrate, which reduces the possibility of local washing out of the crystals the cylindrical part of the separator body due to the formation in sea of compacted surface areas and ultimately results in same to improve the performance section, eat your seperator ability. Installing the ribs on the cone section of the separator body improves the conditions for maintaining the ice and its cut without creating a change in the flow rate of pressing concentrate and wash water, and performing a spiral partition of elastic, anti-friction and hydrophobic material reduces the back flow of the wash water, friction spirals on a rotating cone head and simplifies the construction of the separator according to the conditions of its assembly and operation.
