Description

Technical Field

[0001] The utility model relates to the technical field of sludge treatment, in particular to a sludge purification, concentration and dewatering machine. Background Art

[0002] Sludge treatment is a process of reducing the quantity, stabilizing and rendering harmless of sludge. And the concentration and dewatering of sludge is an important process step widely applied in sludge treatment. Generally, the water content of sludge is relatively high, and it needs to be concentrated and dewatered by flocculants or dehydrating agents before mechanical dewatering. At present, the sludge concentration and dewatering devices on the market mainly achieve the concentration effect by gravity settlement of sludge in a concentration tank.

[0003] The existing patent application number is: CN202223251553.3, and the patent name is: A utility model patent of a sludge concentration and dewatering device. Although this scheme solves the problems of high water content and poor concentration effect of the sludge after being treated by the sludge concentration and dewatering device through a treatment tank and a water pressing mechanism. However, when this sludge treatment equipment is in use, the sludge is injected directly above the filter pressing plate, and the sludge is likely to deposit on the surface of the filter pressing plate. Moreover, during the filter pressing process, sewage continuously overflows from the water overflow hole positions of the filter pressing plate. When draining water, due to a certain height difference between the drain hole and the filter pressing plate, the sewage discharge is not thorough enough, and sewage impurities are likely to remain on the surface of the filter pressing plate, making the hole positions of the filter pressing plate prone to blockage, affecting the working efficiency of the filter pressing plate, and it needs to be improved.

The filter pressing plate 201 is of a hollow structure, and the inner cavity of the filter pressing plate 201 is arranged as a water collecting cavity 203. Overflow holes 2011 for facilitating the overflow of water filtered out from the sludge are arranged at both the upper and lower ends of the water collecting cavity 203; Above the tank body 101, a cleaning brush 204 is arranged for cleaning impurities in the sewage remaining on the surface of the filter pressing plate 201. The brush filaments at the bottom of the cleaning brush 204 are in contact with the surface of the filter pressing plate 201; The cleaning brush 204 is fixed on a rotating support cylinder 205. A push rod 206 is arranged in the inner cavity of the rotating support cylinder 205. The push rod 206 is connected to the telescopic end of the hydraulic rod 202. The rotating support cylinder 205 is connected to a motor 207. The motor 207 is fixedly connected to a support cylinder bracket 208, and the support cylinder bracket 208 is fixed on the inner wall of the tank body 101; The rotating support cylinder 205 is rotatably connected to the support cylinder bracket 208. A driven gear 209 is connected to the top end of the rotating support cylinder 205. The driven gear 209 is connected to a driving gear 210, and the driving gear 210 is connected to the motor 207; The filter pressing unit 200 is arranged above the sludge inlet.

[0034] The drainage unit 300 includes a main drainage pipe 301 and a filter pressing drainage pipe 302. Both the main drainage pipe 301 and the filter pressing drainage pipe 302 are connected to a water pump (not shown in the figure). The main drainage pipe 301 is arranged on the tank body 101 below the sludge inlet. The water inlet of the filter pressing drainage pipe 302 is arranged at the bottom of the inner cavity of the water collecting cavity 203; A pipeline fixing seat 303 is arranged on the inner cavity wall at the top end of the tank body 101.

The filter pressing drainage pipe 302 below the pipeline fixing seat 303 is a corrugated pipe with the functions of stretching and folding, which is used to connect with the filter pressing plate 201 and adapt to the up and down movement of the filter pressing plate 201.

[0035] In this embodiment: During use, sludge enters the tank body 101 through the sludge inlet pipe 102. The highest water level line of the sludge is lower than the inlet of the sludge inlet pipe 102.
