The invention relates to devices for continuous liquid processing of chips, preferably washing and / or impregnation, and can be used in the pulp and paper industry.

The purpose of the invention is to improve the quality of chip processing by improving circulation in a washing or impregnating fluid installation.

FIG. 1 shows a plant for the continuous processing of chips; structural diagram; in fig. 2 shows section A-A in FIG. one; in fig. 3 - view B in fig „2; in fig. 4 is a diagram of the interaction of the blade with scrapers.

The plant for continuous processing of chips contains a housing 1 with nozzles for feeding chips 2 and a liquid 3 and discharging processed chips and waste liquid 4 placed in the housing 1 along its axis a dividing partition 5, part of which is made in the form of a sieve 6, the partition 5, covers continuous the drive chain 7 with scrapers 8 fixed on it, facing one side to the partition wall 5. On the sieve part 6 of the partition wall 5, the Z-shaped blade 9 is hinged to clean the sieve holes 6, The front 10 and rear 11 relative to the rotation of the blade 9 in its transverse section are mounted the pins 12 and 13, and the scrapers 8 with the sides facing the partition 5 have grooves 14 and 15 for the passage of the pins 12 and 13, Mutual

angles between the longitudinal axis of the housing and the lines connecting the center of rotation of the blade with the pins.

the location of the pins 12 and I3 and the slots 14 and 15 is determined by the ratio of 3 g cos &; r-spin l, r coso,;,

r and d are the distances from the axis of rotation of the blade 9 to the pins 12 and 13, fixed respectively on the front 10 and rear P transverse sections of the ramp to the mouth 9;

.y and oL - the angles between the longitudinal

the axis of the housing 1 and the lines connecting the center

rotation of the blade 9 with pins 12 and 13.

The partition wall 5 may have two sections, made in the form of a sieve 6, facing respectively the zones above and below the partition 5 inside the housing 1. In addition, each section 6 is equipped with a blade 9.

The installation works as follows.

By streaming processing (washing or impregnation) of chips through the pipe 2 is fed into the housing 1 filled with process liquid, it fills the gaps between the scrapers 8 and is transported last by means of a continuous drive chain 7 along the trajectory covering the partition 5 to the discharge pipe 4 chesky fluid in the case 1. In about 0

The process of moving inside the chip body 1 is treated with process fluid, which can be used as washing water or impregnating solution, the liquid is fed into the body through the nozzle 3, circulates through the perforations of the sieve 6 and is drained from the installation, for example, into the recirculation system (Fig. 2). When filtering a liquid through a sieve 6, the perforation holes of the latter overlap the chips of chips that are deposited on its surface under the action of a pressure drop, which can be removed using the blade 9.

The blade 9 is driven as follows (Fig. 4). The moving scraper 8 acts on the scythe .12, turning the blade 9 about its axis, the pin 12 at the same time slides along

scraper 8 until it reaches groove 15, pass through it. The next scraper acts on the pin 13, which slides along the scraper until it interacts with the groove 14, the blade 9 in this case being turned in the opposite direction. Then the cycle is repeated.

Thus, due to the shape of the blade 9 and the relative position of the pins 12 and 13 and the groove 14 and 15, when the chain 7 moves with the scrapers 8, the blade 9 receives a reversible circular movement, the bogs working surface of the sieve 6, which improves the circulation conditions of the process fluid through the sieve 6 and, accordingly, improve the quality of chip processing.
