Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a cloth cleaning device for a filter press.

[Prior Art] A conventional device for cleaning the cloth of a filter press has a cleaning pipe that is movable up and down between opposing open plates, and high-pressure cleaning water is applied from this cleaning pipe to the cloth on the surface of the opposing plates. It is starting to erupt towards.

[Problems to be solved by the invention] However, with conventional devices, when high-pressure washing water is sprayed onto cloth, the cleaning wastewater scatters, resulting in the problem that the area around the filter press gets dirty with the washing wastewater.

Therefore, this invention aims to provide a filter press cloth cleaning device having a structure that can prevent high-pressure cleaning water from scattering.

[Means for solving the problem] In order to solve the above problem, this invention
In a filter press cloth cleaning device, elastic bodies are attached above and below the cleaning pipe, the ends of which come into contact with the cloth on the surface of the opposing plate.

[Function] As mentioned above, if the elastic bodies that come into contact with the cloth on the surface of the plate with both ends facing each other are installed above and below the cleaning pipe, the cleaning waste water that is blown onto the cloth surface and scattered will be absorbed by the upper and lower elastic bodies. Since it collides with the opposing surface, its scattering is prevented.

Further, since the elastic body moves up and down together with the cleaning pipe while contacting the cloth, the surface of the cloth is rubbed by the elastic body, so that sludge deposits are efficiently removed and the cleaning effect is enhanced.

[Example] Hereinafter, an example of this invention will be described based on the accompanying drawings.

The filter press shown in Fig. 1 has a horizontal frame 3 that spans the upper surface of a pair of left and right machine frames 2 and 2' that are erected on a base 1, and a large number of plates 4 on the left and right sides of the horizontal frame 3. Each plate is suspended movably, and a cloth 5 is interposed between each plate 4. During the over-process, each plate 4 is tightened by a cylinder 6 to fix the cloth 5, and the dehydrated cake is discharged or When cleaning the cloth 5, the plates 4 are opened to each other as shown in FIG. 1.

As shown in FIGS. 1 and 2, a sliding frame 7 is provided on the upper part of the horizontal frame 3, and a movable table 9 is movably provided on this frame 7 via rollers 8. As the rollers 8 are rotated by the motor 10, the movable table 9 moves the frame 7 in the length direction and stops at an appropriate position.

Support arms 11 are provided on both sides of the movable table 9, extending from the upper part of the outer side of the plate 4 to the lower part of the plate 4. Both support arms 11 are provided with a chain 12 in the length direction, and a chain 12 is provided between the chains 12. A cleaning pipe 13 is installed, and by rotating one chain 12 by a motor 10', the cleaning pipe 13 moves up and down between the plates 4. The cleaning pipe 13 is provided with nozzles 14 at appropriate intervals and is connected to a flexible cleaning water supply pipe 15, from which high-pressure cleaning water is jetted toward the cloth.

Elastic bodies 16 are attached above and below the cleaning pipe 13 in parallel to the cleaning pipe 13. Both ends of the elastic body 16 are brought into contact with the opposing cloths 5, respectively. As the elastic body 16, a material such as a sponge, rubber, or a brush that does not damage the cloth 5 even when rubbed is used. In the case of this embodiment, mounting brackets 17 and 17' are installed on the upper and lower sides of the cleaning pipe 13, respectively.
Variable springs 18 are installed on both left and right sides of the tips of 7 and 17'.
A brush is attached through the cloth 5 so that the brush comes into pressure contact with the cloth 5.

Further, a drainage toy 19 is provided below the cleaning pipe 13 to prevent cleaning drainage from dripping below the filter press as much as possible.

Next, the operation of this embodiment will be explained.

First, the plate 4 is opened as shown in FIG. 1, and the motor 10 and chain 12 are operated so that the cleaning pipe 13 is located below the opened plate 4. Next, the chain 12 is rotated by the drive of the motor 10, the cleaning pipe 13 is moved up and down, and the surface of the cloth 5 is rubbed with the elastic body 16 (brush), while high-pressure cleaning water is supplied from the nozzle 14 of the cleaning pipe 13. is sprayed to wash the cloth 5. After cleaning, the cleaning pipe 13 is lowered below the plate 4, the next plate 4 is opened, the cleaning pipe 13 is moved below the opened plate 4, and the cloth 5 is removed in the same manner as above. Wash.

[Effect] As described above, the cloth cleaning device of this invention has elastic bodies attached above and below the cleaning pipe, both ends of which contact the cloth on the surface of the opposing plate, so that cleaning can be carried out by the elastic bodies. Splashing of waste water is prevented, and since the surface of the cloth is rubbed by the elastic body, the effect of cleaning the cloth is extremely high.
