Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a washing device for washing cloth for dewatering or washing provided in a sludge dehydrator or the like.

When dehydrating sludge using a band press type dehydrator or vacuum r-filtration machine, or separating solid and liquid by r-filtration, solid matter adheres to the surface of the cloth or enters the tissue. This causes clogging and reduces the throughput capacity, and this tendency is particularly strong in the case of viscous materials such as sludge.

Therefore, such p-cloths are constantly washed in a series of washes to remove the solid matter adhering to the r-cloth and prevent a decrease in the p-hyperfunction.

Various types of cleaning devices for this purpose have been disclosed, but one is one in which a large number of nozzles for spraying cleaning water are attached to a water pipe having a length spanning the entire width of the sawcloth. It is widely used.

However, since it is expensive to use tap water or gray water as washing water, in most cases supernatant water from the treated material is used. Suspended residue such as dirt enters and clogs the washing water injection nozzle, and in order to clean it, it is necessary to stop the water supply, which has the disadvantage that the operation of the dewatering machine has to be interrupted during that time.

The present invention aims to solve these difficulties, and aims to provide a cloth washing device that can be easily cleaned without interrupting the operation of the dehydrator. The final objective is to provide a spray nozzle that is not clogged with minute dust, and to provide a washing cloth cleaning device that can clean the inside of a water pipe while passing water using a rotary brush having a built-in nozzle base.

Hereinafter, one embodiment of the fabric washing device of the present invention will be described in detail with reference to the drawings. As shown in FIG. Injection nozzles 4, 4 are arranged in sequence, and in particular, the bases of these injection nozzles are bulged toward the inside of the water tube, as shown in the enlarged section in FIG.

A shaft 6 is provided inside the water pipe 1 and is supported by a stamina box 7 and a shaft support 8 so as to be slidable and rotatable. A brush 5 is installed, and a nodle is attached to the end of a shaft 6 led out of the water pipe so that the brush 5 can be moved or rotated along the axis of the water pipe.

Furthermore, a partition wall 9 is provided inside the water pipe between the drain pipe 3 provided in the water pipe 1 and the injection nozzle group 4, and a hole is bored in the center of the partition wall 9 to serve as a valve seat into which the shaft 6 is inserted. The movement of the valve 10, which is attached to the shaft 6, opens and closes the valve seat hole bored in the center of the partition wall.

In the r-cloth washing device constructed in this way, when washing the p-cloth, if the shaft 6 is pushed in to the 6' position, the valve 10 attached to the shaft 6 occupies the 10' position and seals the partition wall 9. , the brush 5 is at the position 5', and in this state, if the supernatant water of the treated raw water is fed at high pressure from the water supply pipe 2, the injection nozzle 4 whose base bulges into the water pipe will send the supernatant water under daily pressure. can be ejected to efficiently wash sawcloth.

If the inlet of the nozzle is blocked by debris in the supernatant water of the stream water during washing of the sawcloth, by moving the shaft 6 using the handle, the brush 5 will be in a position where it can scrub the bulge at the base of the nozzle 4. The brush 5 is rotated through the shaft 6, and the dust that is clogging the nozzle 4 is wiped away by the brush.
At the same time, the valve 10 opens the partition wall and discharges the pressurized supernatant water from the drain pipe 3 to the outside of the water pipe, so that the debris removed from the nozzle inlet is immediately discharged together with the pressurized water to the outside of the water pipe 1, and the handle is returned to its original position. Just by returning the nozzle, the debris that was clogging the nozzle can be completely removed in a very short time.For example, even in band press type dehydrators, there is no need to stop running the P cloth, and sludge is continuously handled during dewatering. The drawbacks of conventional technology, which hindered the various effects obtained by ensuring the same properties, were completely eliminated.

In the device of the present invention, in order to prevent dirt in the pressurized water from entering the nozzle pipe, the base part is bulged into the water pipe to facilitate removal of adhering dirt. can be instantly discharged out of the water pipe, and it goes without saying that modifications or applications derived from the embodiment shown in the above embodiment are included in the technical idea of the present invention.

Claims (1)

[Claims] 1. Injection nozzles with their bases expanded into the inside of the water pipe are arranged in sequence around the body of a water pipe that has a water supply pipe and a drain pipe at both ends, and a central part is arranged inside the water pipe between the group of injection nozzles and the drain pipe. A partition wall is provided with a hole formed as a valve seat hole, and one end of the shaft along the water pipe axis is guided out of the water pipe through a sealing mechanism such as a stuff-in box by inserting the valve seat hole, and the other end is set as appropriate. A plurality of radial brushes having a length reaching almost the inner wall surface of the water pipe and a valve aligned with the valve seat hole are mounted on this shaft so as to be movable and rotatable in the axial direction. When the valve attached to the rod comes into contact with the valve seat hole and is blocked, the brush comes off from the position of the injection nozzle, and when the valve separates from the valve seat hole, the brush occupies a position where it scrapes the bulging base of the injection nozzle. A P cloth washing device characterized by being attached to each.
