Description

J 1

The invention relates to equipment for washing chips in paper industry.

The circuit of the invention is to reduce the energy intensity of the washing process while simplifying the design of the device.

Figure 1 shows the washer schie, cross section; in Fig.2 a section aa in Fig.1.

The chip washer consists of a body 1 with a loading 2 and a discharge 3 branch pipes installed in the case 1 of the driving drum 4 with blades 5 fixed on its shell and located inside the drum 4 of the discharge screw 6 rigidly connected with it and mounted under the screw 6 of the sieve 7, installed with a gap relative to the shell of the drum 4. In the shell of the drum 4 in the direction of its rotation, in front of the blades 5, loading windows 8 are made. The housing has a branch pipe 9 disposed in its lower part to divert soils; and the washing liquid and the branch pipe 11 for draining excess fluid. The blades 5 are perforated and concave in the direction of rotation of the drum 4. Case 1 has a cavity 12.

Chip washer works as follows.

Contaminated chips through the pipe 2 is fed into the cavity 12 of the housing 1,

652

at the same time, through the nozzle 10, a flushing fluid is supplied under pressure, the jets of which, mixing the chips, wash away contaminating mineral inclusions (stones, sand, etc.) from it, deposited in the lower part of the housing 1 and removed through the port 9. During rotation drum 4 blades 5 grab chips, immersing

it into the washing liquid, the level of which is maintained constant due to the removal of excess liquid through the pipe 11. The washed chips with blades 5 rises above the layer

the washing liquid and when the drum 4 rotates through the loading openings 8 in its shell is fed into the drum 4, where it is picked up by the screw 6 and transported by it to the discharge nozzle 3. During the transportation, the chips are dehydrated first on the perforated blades x 5 and then on the sieve 7, liquid separates from chips, flows through.

the hole of the perforation of the blades 5 and sieve 7.

. Due to the fact that the discharge screw is placed in the cavity of the drum, the device becomes more compact and simple in design. . The drum drive is at the same time the drive of the unloading auger, thereby reducing the energy intensity of the washing process.

Claims (3)
