Description

Dewatering device for industrial waste treatment

The present invention provides a plurality of compression rollers sequentially arranged, a pair of filter cloth belts parallel to each other along the compression roller with sludge interposed therebetween, and the first compression roller from the final compression roller among the compression rollers. A dewatering apparatus for industrial waste treatment comprising a plurality of guide rollers for circulating the filter cloth belt and a sludge supply unit for supplying sludge to an upper surface of any one of the filter cloth belts introduced into the first compression roller. It is installed in the transverse direction of the belt relates to a dewatering device for industrial waste treatment to improve the operation efficiency by automatically washing the injection nozzle of the shower pipe for spraying the washing water toward the filter cloth belt.

4 is a schematic front view of a conventional dewatering device for industrial waste treatment, FIG. 5 is a cutaway cross-sectional view of the shower pipe of FIG. 4, and FIG. 6 is a cross-sectional view illustrating a brushing state in the shower pipe. As shown in these figures, the dewatering device for industrial waste treatment includes a plurality of sequential rollers 111 to 118 sequentially arranged along the squeezed rollers 111 to 118 with sludge 104 to be squeezed therebetween. A plurality of guide rollers for guiding the circulation of the upper and lower filter belts (102, 103) between the upper and lower filter belts (102, 103) moving in parallel with each other and the first pressing roller (111) from the final pressing roller (118) ( 121 to 126, 131 to 135, tension regulators 127 and 136 for adjusting the tension of the upper and lower filter cloth belts 102 and 103, and an upper surface of the lower filter cloth belt 102 introduced into the first compression roller 111. The sludge supply unit 151 for supplying the sludge 104 to the upper filtration pobelt 103, which is circulated between the guide roller 133 and the guide roller 134, toward the upper filtration pobel 103 The cleaning device 140a for spraying the washing water, the guide roller 122, and the guide roller 123 It is to include a cleaning device 140b is interposed between the) to spray the washing water toward the lower filtration four belts (102). Here, the cleaning devices 140a and 140b have the same structure, and the structure of the cleaning device 140a will be described below.

The cleaning device 140a is installed horizontally in the advancing direction of the upper filtration four belts 140a above the upper filtration four belts 103 and has a shower pipe 141 in which a plurality of injection nozzles 142 are formed, and a shower pipe ( It has a valve member 151 which is installed to be detachable to block the end of 141, and a valve member 145 for opening and closing the inflow of the wash water to the shower pipe 141. The valve member 145 is installed between the shower water supply pipe 147 and the shower pipe 141 for supplying the washing water to the shower pipe 141. On the other hand, when the injection nozzle 142 of the shower pipe 141 is blocked by foreign matter contained in the wash water, the valve device 145 blocks the inflow of the wash water, and a valve member provided at the right end of the shower pipe 141. Opening the 143 to insert the brush 161 into the shower pipe 141 to remove the foreign matter of the injection nozzle 142.

By this configuration, when the sludge 104 is dropped to the upper surface of the lower filter cloth belt 102 by the sludge supply unit 151, the sludge 104 is lower filter cloth belt 102 in accordance with the circulation run of the lower filter cloth belt (102) ) Is conveyed to the end guide roller 126 side. At this time, while the water in the sludge 104 penetrates the lower filtration pobelt 102 by gravity, the dehydration proceeds gradually. In addition, the upper and lower filter cloth belts 102 and 103 pass through the final guide rollers 126 and 135 and are wound on the first compression roller 111, and the interval between the upper and lower filter cloth belts 102 and 103 becomes narrower. The sludge 104 is enclosed between the belts 102 and 103 and is transferred from the final guide rollers 126 and 135 to the first compression roller 111. Next, the upper and lower filter cloth belts 102 and 103 with the sludge 104 interposed therebetween are wound and transported from the first pressing roller 111 to the final pressing roller 118 to each pressing roller 112 to 117. The sludge 104 interposed between the filter cloth belts 102 and 103 is compressed and dewatered.

Through this process, the upper and lower filter cloth belts 102 and 103 are spaced apart from each other while passing through the final pressing roller 118, and the sludge 104 is discharged to the sludge cake 105, which has been dehydrated. The upper and lower filter cloth belts 102 and 103 which have completed the compression are circulated through the first guide rollers 121 and 131 along the respective circulation trajectories, respectively, and upward while passing through the guide rollers 122 and 133, respectively. It is cleaned by the cleaning device (140a, 140b) installed in the drive back toward the final guide rollers (126, 135).

By the way, in the conventional industrial waste treatment dewatering device, the injection nozzles of the cleaning devices installed above each of the upper and lower filter cloth belts for spraying the washing water are clogged by foreign substances contained in the washing water. If the washing water is not sufficiently injected into the filter cloth belt due to clogging of the injection nozzle, the dewatering efficiency of the filter cloth belt may be lowered, which may cause sludge dewatering. Therefore, the valve member provided at the right end of the shower pipe is opened to insert a brush into the shower pipe to remove foreign substances caught in the spray nozzle. However, in order to remove the foreign matter of the injection nozzle, there is an inconvenience in that the brush is inserted in close contact with the inner surface of the shower pipe and the brush is repeatedly flowed along the inner surface of the shower pipe. In addition, the washing operation of the spray nozzle of the shower pipe is made in the state in which the industrial waste treatment dehydration device is stopped, there is a problem that the operation efficiency of the industrial waste treatment dewatering device is reduced.

Accordingly, an object of the present invention is to provide a dewatering device for industrial waste treatment, which can automatically clean the injection nozzle, prevent clogging of the injection nozzle, and improve operation efficiency.
