The present invention relates to a belt press type sludge dehydrator, and more particularly, to a belt press type sludge dehydrator having an improved structure for washing a filter cloth.

As industrial civilization develops, many industrial wastes (processing sludge, etc.) are generated in many industries, and these industrial wastes are mixed with water and penetrate the surface of the earth or flow into rivers, thereby causing environmental pollution.

Therefore, the belt press type sludge dehydrator was developed to reduce the amount of industrial waste by minimizing the industrial waste contained in the water and deflowing into the surface by collecting the pure sludge by dehydrating the industrial waste. Industrial waste flowing in between the upper and lower filter cloth consisting of filter cloth is used to dewater by rotating and pressurizing at the same time using a plurality of rollers.

Such belt press type sludge dewatering machine needs to clean the sludge attached to the filter cloth in order to increase the dewatering effect of industrial waste. In the related art, the filter cloth is sprayed by spraying high-pressure washing water toward the filter cloth through a plurality of spray nozzles. Washing methods are used.

However, such a conventional belt press type sludge dehydrator has a problem that the high-pressure washing water is injected into the filter cloth through a plurality of injection nozzles, so that the amount of water consumed for washing the filter cloth may increase.

In addition, a lot of chemicals for reprocessing the consumed water can be consumed, it can take a lot of manpower because it is not easy to manage the device, the device can be aged by the sprayed washing water, the power cost of the high-pressure pump There is a problem that the operating cost of the device can be increased because it can be increased.

In addition, noise and gas may be generated when the washing water is sprayed, and odor may be generated by the generated gas.
