Dynamic pressure solid-liquid separator

Abstract

The invention relates to a dynamic pressure solid-liquid separator which is widely applied to solid control of petroleum slurry, purification of shield slurry, sewage treatment and other industry sectors needing solid-liquid separation. The technical scheme is as follows: dynamic excitation is adopted at the same time on the basis of static pressure filtration to realize solid-liquid separation, and a concrete structure comprises the main components including a pressurizing slurry box, a multilayer vertical filter screen mechanism, a dynamic excitation mechanism, a vibration reduction supporting spring, a spiral chip removal mechanism, a complete machine base and the like, wherein the pressurizing slurry box comprises a slurry inlet, a bucket-shaped slurry box, a slurry collecting pipe, a slurry outlet, a net cage hermetic unit and the like; the filter screen mechanism comprises a layered filter screen, a power driving device, a filter screen supporting hinge and the like; the dynamic excitation mechanism consists of a power source and a vibration exciter; the spiral chip removal mechanism consists of a spiral chip pulling compactor, an automatic weighing chip removal valve and a power transmission component; and the vibration reduction supporting spring can be a metal spiral spring or a rubber composite spring. According to working needs, the dynamic pressure solid-liquid separator can also be provided with a gas remover and a pneumatic or hydraulic filter screen cleaner.

Description

technical field [0001] The invention relates to a dynamic pressure solid-liquid separator widely applicable to petroleum mud solid control, shield mud purification, sewage treatment and other industries requiring solid-liquid separation, belonging to the field of solid-liquid separation. Background technique [0002] At present, various static filtration methods have been widely used in sewage treatment technology, mineral processing technology and food processing technology to realize the corresponding solid-liquid separation. Static filtration methods mainly include extrusion filtration, compressed air filtration and vacuum filtration, all of which aim to deliquify the solid-liquid mixed medium. [0003] The filter press made of the principle of extrusion filtration relies on the huge working pressure of the compacting mechanism to dehydrate the pulp between the filter cloths, and can be divided into belt type and frame type from the structure; compressed air filtration an...

Problems solved by technology

[0004] The existing foreign MAX drilling fluid processor is a single-stage vacuum filtration treatment device, which is a static solid-liquid separation equipment. Because the negative pressure difference (vacuum degree) is limited and it is difficult to maintain a constant vacuum degree, at the same time, the treatment of mud The amount is greatly affected by the properties of the mud (viscosity, specific gravity, composition, etc.), so its practical effect is not ideal, and it has not been widely used so far.
