Description

Cleaning and water saving device for dehydrator filter cloth

The present invention relates to an apparatus for cleaning a filter cloth of a dehydrator for dewatering sludge removed by a water purification plant and a wastewater treatment apparatus. More specifically, the injection nozzle moves left and right by one-way rotation of the driving motor by structural improvement of the washing apparatus. At the same time, while washing the filter cloth in the front and rear overlap, the manufacturing cost is significantly lowered, and the washing and water-saving device of the dehydrator filter cloth that can reduce the operating cost by high pressure injection of the washing water by the ultrasonic wave.

When industrial wastewater is generated from household sewage or various industries at home, the generated wastewater is collected by a water purification plant to purify various harmful substances contained in the wastewater.

When the wastewater is treated as described above, a large amount of sludge is generated. When treating the sludge, it is important to remove water contained in the sludge.

The sludge separated from the wastewater is first introduced into the sludge agitation tank together with the polymer flocculant and reacted to form a floc suitable for dewatering.Then, the sludge is uniformly distributed on the sludge transporting lower filter cloth through a quick chute of the dehydrator. Transfer to dehydration part.

The upper filter cloth is covered on the upper sludge in the process of being placed on the lower filter cloth and transported to the dewatering part as described above, and the sludge is moisturized in the sludge while passing through the pressing roller of the dehydration part in a state located between the lower filter cloth and the upper filter cloth. This will be dehydrated.

The sludge dehydrated in the dehydration part is discharged to the outside of the dehydrator in the form of a cake, and the sludge from which the moisture is removed is incinerated.

In the process of dewatering the sludge as described above, the sludge of the small particles remain between the upper and lower eyelets of the filter cloth, the washing device is installed on the upper, lower filter cloth transport path to remove them.

As described above, the washing apparatus installed on the transport path of the upper and lower filter cloths has already been conceived in various forms.

For example, a typical washing apparatus is one of which is cut off and the other is connected to a hose to supply the washing water pumped from the water warp pump, and a plurality of spray nozzles spraying the washing water pumped from the water pump to the filter cloth There is a tubular stationary washing apparatus installed side by side, and there is an apparatus for washing while moving the injection nozzle.

The fixed type washing apparatus of the above apparatus has a disadvantage in that the washing water is discharged through a plurality of spray nozzles, so that the waste water treatment cost due to waste and waste of the washing water is increased by using a lot of washing water, and between the nozzle and the nozzle. Its spray pressure is low and the cleaning efficiency is reduced, and there is a disadvantage that the effective cleaning is not done in the form of a band. Excessive use of the washing water adds an overload to the aeration tank or the sump tank, as well as operating and treatment costs. This has the disadvantage of increasing.

The method for solving the drawbacks of the washing device is to move the washing water spray nozzle left and right in the orthogonal direction of the filter cloth to wash, which can reduce the manufacturing cost by using less expensive washing water spray nozzle. In order to increase the injection pressure of the washing water, it is necessary to use a high power water pump, as well as a drawback of increasing the amount of electrical energy used to operate the high power water pump.

In the fixed washing machine and the mobile washing machine having the above disadvantages, the washing water is sprayed only by the pressure of the water pump, so that the waste matter (water) mixed in the washing water accumulates in the nozzle for a long time, so that the clogging of the spray nozzle is prevented. It has a disadvantage that occurs.

The present invention was developed to solve the disadvantages of the conventional filter cloth cleaning device as described above, the simplification of the device by allowing the spray nozzle to move left and right in front and rear and width direction of the filter cloth by one continuous rotation of the drive motor At the same time, the spray nozzles are elliptical with respect to the filter cloth, moving forward, backward, and forward and backward to increase the washing efficiency as well as to increase the washing efficiency. It is an object of the present invention to provide a cleaning and water saving device for a dehydrator filter cloth which can reduce the amount of washing water by high pressure injection of the washing water.
