In such cases, conventionally, an injection nozzle connected to a high-pressure water supply source is attached to the pipe, water is injected while rotating the drum, and the pipe is extended by hand, and the nozzle is moved by moving it back and forth. Was to be washed. In cleaning the rolling rolls, a number of spray nozzles were installed near the rolls, and cleaning was performed by spraying a cleaning liquid.

[0003]

[Problems to be solved by the invention]

 When washing the drum of the above-mentioned conventional drum drying device, the method of supporting the injection nozzle by hand is that the nozzle is easy to move due to the reaction force of the jet, a large force is required, and the nozzle is bounced off by touching the drum. The drum was damaged and uniform cleaning was not possible. In addition, in order to wash uniformly with such a method, the pressure of the injection water had to be reduced and the treatment had to be performed for a long time. In addition, it was not always possible to wash well even after long hours of cleaning.

[0004] Further, in an installation type apparatus for cleaning a rolling roll or the like, when cleaning a large number of rolls, a large number of injection nozzles must be provided. As a result, the capacity of the water supply system had to be increased, and the consumption of water, electric power, etc. increased, and the cost increased.

The jet nozzle 2 has a jet port at its tip so as to jet a cleaning liquid such as cleaning water, an aqueous solution of a surfactant, or a solvent at a high pressure. The liquid pressure of the washing liquid is about 100 to 300 MPa, preferably about 150 to 250 MPa for the drying drum of the paper dryer, although it depends on the rotating drum R to be washed. A flexible tube 10 for supplying a high-pressure cleaning liquid is connected to the rear part of the injection nozzle 2 and connected to a cleaning liquid supply device (not shown). The injection nozzle 2 is attached to the movable table 3 so as to be able to move forward and backward, as described later.

The moving table 3 is formed of a main body 11 which is elongated in a direction in which the injection nozzle 2 is moved, and is provided with the injection nozzle 2, a driving unit 6 and the like. The driving means 6 is formed of a reversible motor 12 having a variable speed reduction function as a driving device, a transmission 13 connected thereto, a shaft 14 driven by the transmission 13, and a shaft 14. It has a female screw member 15 and the like screwed into a male screw. The injection nozzle 2 is attached to the moving table 3 via the female screw member 15. Further, a sliding surface 16 is provided on the main body 11 along the shaft 14, and the rotation of the female screw member 15 is regulated by the sliding surface 16 so as to move. A shaft 14 is attached by a bearing so as to project from the surface of the main body 11. The forward / reverse rotation of the shaft 14 causes the female screw member 15 to move forward / backward, so that the injection nozzle 2 moves forward / backward on the movable base 3.

At least one end of the sliding surface 16 of the movable base 3 is provided with a limit switch (not shown) for stopping the advance of the female screw member 15 and reversing the same. Then, when the injection nozzle 2 reaches the end, the injection is automatically stopped and the injection nozzle 2 is moved backward. As a result, it is possible to automatically perform the cleaning for each movement of the moving table 3. The moving speed of the injection nozzle 2 is set so that the rotation width of the cleaning liquid moves by one rotation of the rotary drum R. At the time of cleaning, the moving speed of the injection nozzle 2 may be kept constant and the number of rotations of the rotary drum R may be changed. For safety reasons, measures such as covering the moving parts of the transmission 13 are taken.

A support member 18 is provided at a lower portion of the main body 11 of the movable base 3, whereby the movable base 3 is mounted on the slide rail 4 via the support member 18 so as to be able to advance and retreat. I have. The support member 18 is provided with an engagement recess 19, and the engagement recess 19 is fitted into a locking ridge 20 provided on the slide rail 4. The moving table 3 is configured to move forward and backward along the slide rail 4 by moving means 5.

The slide rail 4 is formed of a pipe-shaped member, and is formed of a member longer than the width of the rotary drum R so as to guide the movable table 3 in the longitudinal direction of the rotary drum R. A locking ridge 20 is provided in parallel with the axis of the slide rail 4 so that the movable table 3 does not rotate freely. The slide rail 4 is fixed to the support by the clamp 9 so that the locking ridge 20 is positioned in the required direction so that the injection nozzle 2 is directed to the required position of the rotary drum R. By doing so, the liquid can be ejected in the optimal direction, and a plurality of rotating drums R can be washed only by changing the setting of the slide rail 4 with one setting of the support, so that the cleaning effort is reduced. We can save. The structure is simple because a clamp is used.

The moving means 5 is a device for moving the moving table 3. In the present embodiment, a male screw and a female screw are provided at both ends using a pipe-shaped material so that the movable base 3 can be moved manually, so that a plurality of these can be connected. I have. When the position of the movable base 3 is to be moved far away, it is used by adding a link and lengthening it. With this configuration, it is possible to reduce the size of the storage device by using a simple structure.

When the rotating drum R is washed, first, the moving table 3 is moved so that the injection nozzle 2 is positioned at the near-side end of the moving table 3 and at the near-side end of the rotating drum R. 5 to move to a predetermined start position. Therefore, the rotating drum R is rotated while the spray nozzle 2 is advanced by the drive means 6 at a constant speed from one end of the movable table 3 to the other, and the cleaning liquid is sprayed onto the surface of the rotary drum R for cleaning. When the injection nozzle 2 reaches the end of the moving table 3, the injection of the cleaning liquid is stopped and the injection nozzle 2 is retracted. Further, the moving table 3 is moved by the moving means 5 so that the cleaning nozzle 2 is located at the position of the uncleaned end, and the cleaning is performed. This operation is repeated to wash the rotating drum R from one end to the other.

Next, a method for cleaning using the rotating drum cleaning apparatus configured as described above will be described. First, the columns 8 are fixed to the frames 7 at both ends of the rotary drum R, the slide rails 4 are stretched between the columns 8, and the movable table 3 is installed on the slide rails 4. The slide rail 4 is fixed to the column 8 by the clamp 9 in the direction. Next, the moving means 5 is attached to the moving table 3 and pressed to move the moving table 3 so that the injection nozzle 2 is positioned at the front end of the rotary drum R and fixed.

The cleaning operation is performed by rotating the rotary drum R, injecting the cleaning liquid from the injection nozzle 2, operating the motor, and moving the injection nozzle 2 forward by an injection width, for example, 2 mm per rotation of the rotary drum R. . When the injection nozzle 2 has moved by one stroke on the movable base 3, the limit switch is operated to stop the injection and retreat. At the same time, the moving table 5 is pushed to move the moving table 3 forward by one stroke to fix the moving table 3. Then, the motor is again operated to operate the driving means 6, and the cleaning operation is performed by injecting the cleaning liquid.

The operation of moving and installing the injection nozzle 2 and the operation of cleaning are repeated, and after the cleaning of the rotary drum R from one end to the other is completed, the next rotary drum R is cleaned. In this case, if the support is set so that the adjacent rotating drum R can be washed only by changing the injection direction of the injection nozzle 2, a plurality of drums can be washed with one setting of the support. Labor can be reduced. When the moving table 3 is moved by the moving means 5, if a long roll becomes insufficient, screws may be screwed together.

According to the rotary drum cleaning apparatus of the present embodiment, the labor can be reduced, the drum can be prevented from being damaged, and a favorable uniform Can be washed. As compared with a device having a large number of injection nozzles, the number of injection nozzles can be reduced, the capacity of equipment such as a water supply device can be reduced, and the consumption of water, electric power, etc. can be reduced.

In the above description, an example in which the drum cleaning device is used for cleaning the rotating drum has been described. However, the present invention is not limited to this. Can be applied to In addition, although an example has been described in which the moving means is manually used by being connected by a pipe-shaped member, the moving means may be self-propelled using power. The self-propelled type can reduce the labor required for cleaning. Further, although an example is shown in which one injection nozzle is used, a plurality of nozzles may be provided to the same rotating drum, or may be provided to different rotating drums. In this way, good and quick cleaning can be performed, and the cleaning operation time can be reduced.
