Description

A kind of vertical sewage sludge or pulp lifter are dehydrated separator

Technical field

The utility model relates to sewage sludge processing equipment technical field, it is specifically related to a kind of vertical sewage sludge or slurry Material promotes dehydration separator.

Background technique

Have in the muddy sludge largely precipitated, such as septic tank, cesspit fresh sewage in conventional sewage processing, And in the sewage after flocculation disposition, there are a large amount of suspension sludge further to dispose.These moisture percentage in sewage sludge are very high, Similar with the excess sludge in sewage plant sedimentation basin, moisture content can reach 99% or so；This kind of Sewage containing the dress particle that suspends Mud quantity is more, volume is big, has to pass through further separation disposition, reduces volume to reduce moisture content realization, facilitates in next step It sets.It simultaneously in wet process powder grinding technics, also needs to be disposed the slurries after having ground, realizes suspended particulates and liquid point From.

The conventional methods disposed at present are that the sewage sludge that these are contained to the dress particle that suspends or slurries are taken with pumping, are sent To the processing of later separation processing equipment.Wherein there are the following problems: first, can not distinguish sewage sludge or slurries, causing to take out Taken amount is big；Second, causing the energy consumption of pump high, most energy consumptions are wasted onto the extraction of liquid, only small part since extraction amount is big Energy consumption is extracted for sludge or slurry；Third, a large amount of muddy sludge or slurries extract the workload for leading to subsequent processing process Greatly, corresponding equipment also needs to configure big volume, high-power, causes whole waste；Fourth, suction pump majority runs at high speed, it is easy to inhale The bulks solid materials such as attached some bricks, stone, the problems such as causing pump seizure and damage；Fifth, suction pump majority is centrifuged using blade Pump, there are sucks sewage/liquid to be easy, and aspirates thick sludge/slurry scarce capacity.

Existing scientific and technical personnel notice that the sewage sludge containing the dress particle that suspends or slurries moisture content height lead to subsequent disposition The big problem of equipment investment, and relevant device is developed, but majority is combined using multiple equipment to reduce moisture percentage in sewage sludge；Such as China Patent 201720981107.8 provides a kind of screw extrusion dehydration device, takes muddy sludge by sewage dirt pumping first Afterwards, then using power device driving helix extrusion device to squeeze sewage sludge has been extracted, sewage is along on cylindrical filtration cartridges Annular water tank filters and goes out, and sludge promoted along main shaft and filters pressing is to 95% moisture content, subsequently enters at follow-up equipment Reason.The technology realizes certain sludge dewatering, and reduce the extraction amount of sludge, but there are the following problems: the first, technique is multiple It is miscellaneous, it is taken using sewage sludge pumping and carries out the dehydration of screw extrusion dehydration device after sludge again to reduce sludge quantity, structure is also complicated； The second, energy consumption is relatively high, and the extraction and minimizing for realizing sludge are combined using multiple equipment；Third does not solve sewage dirt Pump, which runs at high speed, adsorbs the problem of substance such as brick, stone, and the 4th, mud-water separation, separating effect are carried out by the annular water tank on filter cylinder Difference, impure height in water outlet, and low separation efficiency.

201720840643 .6 of patent provides a kind of sewage sludge separator, is mainly used for the muddy extracted Sludge；It includes the hollow axles of an outer side band strainer, drive shaft high-speed rotation by motor, realize that muddy sludge exists Realize mud-water separation under centrifugal force and inside and outside dual screw propulsion.The first, complex process, after taking sludge using sewage dirt pumping It carries out centrifugation and screw extrusion dehydration again to reduce sludge quantity, causes apparatus structure complicated and energy consumption height；Second, it dallies in Axis high-speed rotation realizes centrifugal dehydration, and shaft inertia is big, causes dehydration energy consumption high；Third can not be set on hollow axle Set a large amount of strainers, filter capacity and poor filtration effect；4th, it does not solve sewage dirt pump and runs at high speed and adsorb the objects such as brick, stone Geological Problems.

How for the sewage sludge containing the dress particle that suspends or slurries to develop that a kind of structure is simple, and technical process is reliable, And suspended matter and water/slurry separation are able to achieve to reduce the dehydrating equipment of sewage sludge or slurries amount as a urgent need.
