Description
Technical field
The utility model relates to the equipment for separating liquid from solid utilizing filter core to tackle silt in seawater and microorganism, is specifically related to the liquid-purifying peculiar to vessel and the purifier that adopt the nested filter core of stage differential style.
Background technology
Solid-liquid separation technique is the technical method be commonly used in liquid-purifying and process for purifying, wherein utilizes filter element filtering to obtain engineer applied widely as simple and effective separation method a kind of in this technology.Its principle is when solidliquid mixture flows through the cartridge surface being covered with hole, and penetration by liquid hole flows through filter core, and most of solid is due to size, and than hole, large or bridging action to be retained by filter core thus realizes Separation of Solid and Liquid.The size of its mesopore is called the precision of filter core, and precision is higher, and hole is less, and the particle diameter of its solid particle that can retain is also less.
When using filter core to carry out Separation of Solid and Liquid, inevitably produce the situation that filter core blocking affects separation process, this is due in separation process, the solid matter be trapped constantly is accumulated in cartridge surface, make hole more and more less, made flow resistance increasing, and caused overcurrent flow more and more less, finally cause the interruption of separation process.Therefore be the necessary means ensureing normal operation to the backwash of filter core.Namely backwash is removed by the dirt being accumulated in cartridge surface, and form dope and discharge, thus make filter core return to clean conditions, the quality of its developing result directly has influence on the service life of filter core.In order to the carrying out making separation process energy efficient, lasting, when carrying out Separation of Solid and Liquid to certain particular liquid, suitable filter core precision and structure must be selected, should separating effect be ensured, ensure that there is good contamination resistance and backwash effect again.Mentioned above principle is even more important for process seawater.Natural sea-water is a kind of Component comparison complexity and changeable liquid, when sea is tranquiler, solid constituent is wherein zooplankter and phytoplankton mainly, its grain diameter is less, when surge is larger, except in vitro is also mingled with many silt, its grain diameter is biological ten times even more than hundred times.Be directed to the main following several mode again of equipment for separating liquid from solid of process seawater at present, all have certain defect
In order to ensure halobiontic clearance, directly adopt the device of degree of precision filter core, when running at the higher special time of sediment charge or specified sea areas, filter core is easily caused to block serious, backwash process frequent starting, and poor effect, processing procedure is greatly affected.
Adopt the mode of multistage filtering series connection, be about to adopt the device of lower accuracy filter core to connect with adopting the device of degree of precision filter core, prime is for removing silt, and rear class is for removing biology.This form volume is comparatively large, is not suitable for the environment peculiar to vessel of narrow space.
Utility model content
For defect of the prior art, the purpose of this utility model is to provide a kind of stage differential style automatic backwash seawater equipment for separating liquid from solid, and for Seawater Treatment, volume is little, and adapt to marine condition, automaticity is high.
For achieving the above object, the technical scheme that the utility model adopts is as follows:
A kind of liquid-purifying and purifier, comprise body and filter core, also comprise a backwash mechanism;
Described body is a cylindrical shell, for installing described filter core and backwash mechanism, arranging an intermediate plate and housing being divided into two chambeies, be respectively soil chamber and clear water chamber in the middle part of described cylindrical shell, and water inlet connects soil chamber, and delivery port connects clear water chamber;

The pressure reduction of two cavitys detects by the differential pressure pickup connecting soil chamber and clear water chamber in described backwash mechanism, and pressure difference signal is transferred to controller, backwash electric machine rotation is controlled by controller, the rotating suction disc driving suction inlet to be close to filter core lower surface rotates, and then control of sewage disposal valve is opened, under differential pressure action, the water in clear water chamber oppositely flows through filter core successively and exceeds filtering layer and low filter course, is departed from by dirt.
Described body is a cylinder, for installing filter core and backwash mechanism, and carries out the fluid space excessively of filtration treatment as liquid.
Described filter core is cylindrical.
Described filter core is according to pretreatment flow preparation different size and quantity, and multiple filter core is circumferentially uniform.
Inside and outside described filter core, the precision of filter course is differential is an order of magnitude.
After filter process starts, sewage is by the soil chamber of water inlet access to plant, filter core inside is entered through filter core lower surface, from inside to outside through filter course, first oarse-grained pollutant is trapped within internal layer, short grained pollutant is by being retained by skin after internal layer, and clear water is discharged by delivery port by entering clear water chamber after filter core.
The upper surface of described inside and outside filter course is all welded with shrouding, an inner flange is welded in outer filter course lower surface, an outward flange is welded in inner filtration layer lower surface, be bolted, and sealed by rubber sheet gasket, the outward flange of inner filtration layer being welded with threaded connector for being connected and fixed with intermediate plate, enclosing sealing function during connection by the O type of thread-rolling screw connector root, threaded connector lower surface is uncovered as intake tunnel.
Described backwash motor is arranged on body top board, is connected with rotating suction disc by rotating shaft, and the suction inlet of rotating suction disc is close to filter core lower surface, and rotating suction disc is connected with blow-off pipe, and automatic blowdown valve installed by blow-off pipe, and blow-off pipe end is sewage draining exit.
Close after described blowoff valve delayed start-up, a filter-core back-flushing washes end, controls backwash motor and is rotated further, arrive next filter core place and again perform backwash process.
The proximity switch that is located through rotated output signal, and after revolving and turning around all filter-core back-flushings are washed one time, backwash process stopping, when a filter core is when carrying out backwash process, other filter core is still filtering, and whole backwash process does not affect filtration.
The utility model can solve concentration of suspension change greatly and the filtration problem of seawater that differs greatly of grain diameter and the problem of shipborne equipment miniaturization.The mode of differential filtration makes the water environment capacity distribution ratio of filter core comparatively evenly and the particle size that can tackle it separately of the filter core of different accuracy is pointed, and contamination resistance promotes, and resistance rises comparatively slowly, improves filtration continuation.The structure of nested type makes the space shared by filter core of certain filter area reduce, and is conducive to the miniaturization of device, adapts to the high request of environment peculiar to vessel to space utilization.Simultaneously because backwash process is full automatic, decrease the cost that personnel safeguard, improve the reliability of equipment.
