Halfway problem, and filter plate is the main corollary apparatus of plate and frame type filter-press for separation of solid and liquid, filter effect quality and filter
Plate has very big relationship, if there is compared with juicy in the filter residue after separation, will have a direct impact on product quality, is sticked to shadow on filter cloth
Ring discharge rate, increase filter cloth cleaning difficulty, seriously affect production efficiency, thus provide a kind of easy to use, high production efficiency,
The good dehydration device again for filter residue in filter plate of filter residue dehydrating effect.
Summary of the invention
The purpose of the invention is to overcome the deficiencies in the prior art, and provide a kind of easy to use, high production efficiency, filter
The good dehydration device again for filter residue in filter plate of slag dehydrating effect.
The object of the present invention is achieved like this: a kind of dehydration device again for filter residue in filter plate, it includes filter plate,
Fluid hole on the filter plate passes through pipeline and is connected on vacuum pump, offers through-hole on the filter plate avris, described
It is provided with working medium pipeline in through-hole, has the working medium circulated inside the working medium pipeline, is followed by the flowing composition of working medium
The heat pump system of ring, the pipeline are tightly connected with the fluid hole of corresponding each connection, and the heat pump system includes pressure
Contracting mechanism, condensing mechanism, expansion mechanism and evaporation device.
The condensing mechanism is made of working medium pipeline, and the throttling of working medium pipeline is in parallel.
The working medium pipeline is assemblied in inside filter chamber by what through-hole was uniformly adapted to, and the diameter of working medium pipeline is no more than filter
The depth of room.
The heat that the condenser pipe releases is flowed between two filter plates by through-hole, and the inlet air flow of through-hole is much smaller than true
Sky pump goes out air-flow.
Beneficial effects of the present invention: the present invention is to be dehydrated again to filter residue, after filter press squeezes to reach
More low-moisture requirement in filter residue first passes through vacuum pump against the filter residue air-breathing in filter plate, siphons away between filter cloth when in use
Steam reduces the gasification temperature of water so that the cavity between two filter plates forms the state of ultralow pressure, then passes through heat pump cycle system
System absorbs the heat of surrounding, the heat of absorption is transferred completely between two filter chambers by condenser system, so that filtering in two filter plates
The moisture fast vaporizing of slag, then taken away by vacuum pump, so that the moisture in filter residue is lowered again, reach filter residue compared with low moisture
Requirement substantially reduce the processing time of filter residue to mitigate the cleaning difficulty of filter residue and the cleaning difficulty of filter cloth, improve
Production efficiency significantly reduces the moisture in filter residue；Total, the present invention has easy to use, high production efficiency, filter residue de-
The good advantage of water effect.
