Description

The invention relates to the canning industry, namely to the wiping machines.

A well-known wiping machine contains a screen drum, encased in a casing, inside of which there is a shaft with whip holders and tape scourges fixed on them, a pressure hopper, discharge hoppers and a drive.

The disadvantage of the prototype is the low specific wipe capacity, under which the amount of wiped product that has passed through the active sieve area per unit of time rises. This is due to the fact that the raw material picked up by the rapidly rotating scourges, moves at a certain speed from the inlet to the outlet, likewise along the path of wiping the liquid phase separated by centrifugal force. On the way of wiping, the volume of the product varies from the maximum at the inlet to zero at the outlet, as a result of which the centrifugal pressure of the pulp along the sieve also drops from the maximum to zero.

The aim of the invention is to increase productivity.

The goal is achieved by the fact that in a wiping machine containing a screen drum with casing, inside which is installed a shaft with whip holders and tape fasteners fixed on them, a pressure hopper, discharge hoppers and a drive horn, the holders have an annular shape relative to the shaft and are equipped with additional scuttles located radially along the shaft forming the chambers, the shaft being made hollow and having openings for communication with the chambers of the wiping chambers,

15 whips are located two between the wiping chambers, and in each wiping chamber a radial whip is additionally fixed.

FIG. 1 shows a schematic image 20 of the proposed wiper, general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 - sweep the cleaning chamber; in fig. 4 - isometric car.

In addition, within the chambers there are scourges 8 with a zero angle of anticipation for increasing the wiping intensity, and between the chambers on the ring housings 9, band strings are fixed 10 with a negative lm angle of advance n 11 with a positive angle of advance. The pest set is interconnected by ring pins 1U1 and 9. The machine also contains a pressure hopper 12 with an overflow device 13, times the load bins: drain 14 and for waste 15, frame 16, drive 17. High pressure in chambers 5 is provided by the total pressure generated by the centrifugal force of injec tion when the shaft rotates and the hydrostatic pressure of the pulp column is supplied from the pressure hopper. Small works as follows. Pulp from the hopper 12 through the hollow shaft 3 through the holes 4 is fed into the chambers 5 and fills them completely. When the engine is turned on, the wiping process starts, while in the chambers 5 a high pulp pressure is created both by centrifugal inertia and This is due to the hydrostatic head formed by the hopper 12, the pulp level in which is supported by the overflow device 13. Thus, a high-pressure wiping is carried out over the entire cross section of the chambers 5 against the perforated surface of the drum 1. The cleaned pulp is compensated for by entering it from the hopper 12. A certain amount of pulp will penetrate into the gap between the rear end wall 7 of the chamber 5 and the perforated drum 1. This amount of pulp is captured by the scissors 10 with a negative angle of support, further rubbed and moved from the exit to the beginning of the sieve drum, where it is transferred to the pests 11 with a positive angle of advance, which finishes and scraps the waste into the bunker 15. The rubbed mass is removed from the machine through the bunker 14. E An experiment to test the model of an over-pressure wiper, 0.02-0.06 MPa of the wiped product, which is fed over the entire surface of the sieve drum, showed that the specific wiping ability of the sieve with 0.4 mm hole diameter is 10 times larger, than in the T1-KP 2D wiping machine, which is a single row machine with the T1-KPH machine, at its maximum performance. Considering that the design of the proposed wiping machine includes high-pressure chambers, which ensure an even supply of the wiped raw material to the sieve drum over almost its entire area, the specific wiping capacity of the sieve in the machine will be significantly higher than that of the T1-KPH wiper. The use of the proposed design makes it possible to increase the productivity of machines1 1 by 2-6 or more times depending on the type of raw materials being cleaned while maintaining the dimensions of the prototype - T1-KPH machine due to the introduction of high-pressure chambers into the design, as well as the use of scourges coaxial to the machine shaft , intensifying the processes of pulp grinding and cleaning the perforation of the perforated drums. Claims of the Invention The wiping machine contains a screen drum that is encased, inside which a shaft is installed with flap holders and tape scourges fixed on them, a pressure hopper, discharge hoppers and a drive that, in order to increase productivity, the trash holders have an annular relatively the shaft is shaped and provided with additional whips located radially along the shaft forming the chambers, the shaft being hollow and having openings for communication with the chambers of the wiping chambers chi disposed between two wiping chambers, and each chamber further pulping fixed radial whip.
