Description

Cleaning device behind sieve of bent sieve

Technical Field

The utility model relates to a sieve and strain production and processing technical field, in particular to belt cleaning device behind sieve of bent sieve.

Background

The pressure curved sieve is a high-efficiency sieving device provided with a 120-degree arc-shaped pressure curved sieve surface, and wet materials are separated and classified by pressure. The material enters the concave screen surface from the tangential direction of the screen surface at a certain speed (15-25M/S) from the nozzle, the material is subjected to the action of centrifugal force, gravity and resistance of the screen bars to the material on the screen surface due to a higher feeding speed, the sharp cutting edge of the screen bar can cut the material in the process that the material flows from one screen bar to the other screen bar, at the moment, starch and a large amount of water in the material pass through the screen slits to become undersize materials, and fiber fine slag flows out from the tail end of the screen surface to become oversize materials.

The size of the gap between the screen bars is 0.050mm, 0.075mm and 0.1 mm. After the screen surface is used for a period of time, because the gaps between the screen bars are very small, the gaps are easily plugged by fiber fine slag, so that the screening effect of the screen surface is reduced, and the service life of the screen surface is reduced. The current industry practice is that an operator holds a high-pressure water gun to wash a screen surface from the front door direction to wash away fiber fine slag, and partial areas cannot be washed by manual washing. But the gap shape between the grating is similar trapezoidal, is trapezoidal minor face from the direction of the front door, is trapezoidal long limit from the direction of the back door, dashes the thin sediment of fibre from the direction of the front door, and the effect is not as good as back door direction and washes far away. And because the machine is shut down when washing, the valve of sieve case feeding is operated in the front door direction, if wash from the back door direction, must also have 1 workman to be responsible for operating the valve in the front door direction, increase labour cost.
