Filter cloth cleaning device of belt press type dehydrator {omitted}

The present invention relates to a filter cloth cleaning device of a belt press type dehydrator which dewateres sludge generated during wastewater purification treatment to remove water in the sludge, and in particular, improves the cleaning efficiency of the filter cloth, and is easy to maintain and maintain. The present invention relates to a filter cloth cleaning device of a belt press type dehydrator capable of preventing economic loss and of preventing malfunction and departure due to a change in tension of the chain belt.

When industrial wastewater is generated from household sewage or various industries at home, the generated wastewater is collected into a reservoir 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.

In order to remove water in the sludge, the sludge is first introduced into the sludge agitation tank together with the polymer flocculant and reacted to form a suitable floc for dewatering. Then, the sludge is uniformly distributed on the sludge transporting lower filter cloth through the dehydrator steep chute. Transfer.

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. 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.

As an example, the "filter cloth cleaning device of the belt press type dehydrator" registered under Utility Model Registration No. 178979 may be exemplified.

The above-described design makes it possible to clean the filter cloth while the washing nozzle reciprocates while operating the chain belt, which is the conveying means, in one direction.

The cleaning device reciprocates the cleaning nozzle while rotating the chain belt in one direction, thereby eliminating the torque phenomenon generated when the cleaning nozzle is reciprocated by rotating the driving source, ie, the driving motor, forward and backward, respectively, and installed on a pair of chain belts. As a result, the filter cloth is not only improved by washing the filter cloth while moving in the direction crossing each other, and the filter cloth is prevented from being damaged by the frictional wear as the use of the brush is excluded by the cleaning force.

However, the filter cloth cleaning device, first, the washing water sprayed through the nozzle is sprayed only by the pumping pressure of the water pump, when using the cleaning device for a long time, the waste (water) mixed in the wash water is a nozzle Not only has the disadvantage that clogging of the injection nozzle is accumulated, but it also removes contaminants remaining on the filter cloth depending on the injection pressure of the washing water. Have;

Second, the chain belt and the main body, which are the power unit, are integrally constructed so that in the event of a failure, the entire cleaning system must be separated, as well as the labor and labor time required, and the economic burden of maintenance increases. Has disadvantages;

Third, the chain belt is always tensioned even when the washing machine is stopped, which causes the chain belt to be sluggish when it is used for a long time. In addition, the chain belt is rotated at high speed due to the chain belt's slowness. Has a problem that is disengaged from the sprocket.

The present invention devised to solve the disadvantages of the conventional filter cloth cleaning device as described above, it is possible to wash the filter cloth contaminated by the grease by vibration and disturbance, degreasing, emulsification generated from the ultrasonic device installed in the cleaning nozzle, independent Since the cleaning device is assembled by components, it is possible to separate parts in case of failure, minimizing working time, labor, and economic burden due to maintenance, and it is necessary to apply tension to the chain belt only when the cleaning device is operated. It is an object of the present invention to provide a filter cloth cleaning device for a belt press type dehydrator which can prevent the separation phenomenon due to the change in tension of the chain belt.
