Description

[Technical Field] The present invention relates to a sludge cake hopper leachate collection device,

The present invention relates to a sludge cake hopper leachate collection device, and more particularly, to a sludge cake hopper leachate collection device capable of easily moving a leachate receiver for receiving leachate leaking from a cake hopper without using any electric energy, The present invention relates to a sludge cake hopper leachate collection device capable of improving the convenience of the operator in both cases of loading cakes and collecting leachate.

Raw water or wastewater to be treated in purification plants and wastewater treatment plants contains a large amount of various kinds of solid matters including various organic substances. Such solid matters are accumulated through sedimentation and filtration during the purification process of water, wastewater and wastewater. The accumulation is called sludge.

Currently, sludge generated through various water treatment processes is mostly landfilled with landfills and buried with general garbage, except that only a part of the sludge is used in agricultural land or used as feed for earthworms.

As a result, a large amount of leachate is generated, and there are many problems such as odor due to decay of residual organic matter of the sludge, pollution of the groundwater in the soil, and secondary environmental pollution problem around the landfill.

Therefore, it is preferable that the moisture content of the sludge is as small as possible. Accordingly, the sludge generated through various processes is generally subjected to a dehydration process, and the dehydrated sludge is stored in a cake hopper do.

Although the sludge cake stored in the cake hopper is conveyed to a landfill or the like by a vehicle, the water content of the sludge cake is about 80% even in a state where the sludge cake is stored in the cake hopper, And the remaining water in the sludge cake is leached as time elapses. That is, since the leachate is generated from the sludge cake temporarily stored after dewatering, there are the following problems in storing the sludge cake in the conventional cake hopper.

First, a conventional cake hopper provided for temporarily storing a dehydrated sludge cake before being taken out of the room is discharged through a gate provided under the cake hopper in a state where the vehicle is stopped at a lower portion of the sludge cake, The lower gate of the bottom of the cake hopper, through which the sludge cake is discharged, is provided with a pair of doors that are opened and closed at both sides, and a pair of doors And a pair of driving cylinders.

A gap is formed in the central portion of the gate so that one side of the pair of doors is in contact with each other, and the leachate from the sludge cake flows out through the gap to contaminate not only the cake hopper but also the bottom of the hopper, And the leachate leaking out is a violation of the water quality environmental law, which is subject to legal punishment.
