Problems solved by technology
The structures of these known dehydrators are all complicated, the volume is relatively large, and the energy consumption is relatively high, which increases the cost of sludge dewatering
At the same time, the sludge output of these devices is discontinuous, and sometimes the waste sludge on the raw surface will produce capillary phenomenon.
[0003] Patent No. CN1666965A discloses a waste sludge dehydration device, which dehydrates various waste sludge produced on the industrial site through cake formation. high

Embodiment Construction
[0016] In order to achieve the above purpose, the present invention includes two parts, a dehydrator body 1 and a purging device 2, wherein the dehydrator body 1 includes a raw liquid inlet 11, a filter element 12, a filtrate pipe 13, a liquid collection pipe 14, a filtrate outlet 15, and a filter cake outlet 16 , raw liquid outlet 17, overflow port 18, purge pipe 19, purge device 2 is made up of valve 21, valve 22, valve 23, filter pump 24 and filtrate tank 25.
[0017] The stock solution is pressed into the dehydrator body 1 through the stock solution inlet 11 for filtration and dehydration. The filtrate passes through the filter core 12 to the filtrate pipe 13 , is collected by the collecting pipe 14 , and is finally recovered in the filtrate tank 26 through the filtrate outlet 15 under the suction of the filter pump 25 . When the stock solution in the dehydrator body 1 is excessive, it returns to the stock solution tank through the overflow port 18 .

The invention provides a plum tube type membrane separation sludge dewatering device, which comprises a dewatering machine body and a blow washing device. The central dewatering part of the dewatering machine body is a plum tube type separation membrane element, and the blow washing device consists of an air washing part and a water washing part. The liquid contact part of the plum tube type membrane separation sludge dewatering device does not use metal at all, the internal material of the machine shell of the dewatering machine body is resin liner; the material of the filer is polypropylene (PP) and the like; and a metal corrosion problem thus is avoided. The sludge dewatering device disclosed by the invention is capable of automatically drying and discharging filter cake obtained after filtration, cleaning filter cloth and the like. Without any driving device, the structure of the device is simple, and the device is capable of handling large filter area. In addition, a sealing part which is very important for the filter is a sealing hose, so leakage-free stable dewatering filtration is realized.
Description
technical field [0001] The invention relates to a sludge dewatering device, in particular to a sludge dewatering device with a quincunx membrane element as the core component, which can dehydrate sludge produced by various waste waters. Background technique [0002] In the process of sewage treatment, a large amount of sludge will be separated and produced. The sludge has a high moisture content and is in a fluid state. The subsequent treatment is very difficult. In order to facilitate the treatment and disposal of the sludge, the sludge needs to be dehydrated. The cost of sludge dewatering accounts for about 15% of the total treatment cost. Therefore, it is very important to reduce the energy consumption of sludge dewatering. At present, the commonly used sludge dewatering equipment mainly includes rolling sludge dewatering machine, belt filter press dewatering machine, plate and frame filter press dewatering machine and traditional extrusion equipment. These known dehydra...
