The filter that present water treatment field generally uses has more medium filter and soft filtering material filter, the filtrate that the former adopts mostly is quartz sand, anthracite, garnet and walnut shell etc., latter's filtrate is soft filtrates such as synthetic fibers, as fibrous nodules (comprising the comet type corpus fibrosum) etc.Common soft filtering material filter utilizes filtrate deadweight and waterpower compression filter material layer at present, and filtering accuracy preferably can reach median particle size≤3 μ m, is better than more medium filter.But filter effect is all undesirable, and two kinds of filters all can not reach the filtering accuracy requirement of suspension≤1mg/L, median particle size≤1 μ m to the clearance of suspension and suspended particle diameter index.If require to reach this index request, then must adopt membrane technology, and adopt the technical scheme of membrane technology to exist film to pollute and the cleaning problem, that is that all right is ripe or investment is too high in the industrial applications of some industry.For this reason, the applicant has applied for that on August 13rd, 2002 application number is 02125489.3, name is called the Chinese patent of " a kind of fiber ball filtering device ", this patent provides a kind of machinery compressible fiber ball filter, filtering accuracy preferably can reach the filtering accuracy requirement of suspension≤1mg/L, median particle size≤1 μ m, reach the level of micro-filtration membrane, the technical scheme of this patent application simultaneously exists equipment to install that floor space is big, the device space is high, is not suitable for the problem of large-scale municipal water treatment.
Summary of the invention
At above-mentioned problems of the prior art, the purpose of this utility model provides the compressible filter of upward flow, and it is by changing the direction of a stream of water, make filtering accuracy higher, the rate of filtration is faster, changes the draining tank structure simultaneously, and the equipment that dwindled is installed floor space and space.
For realizing above-mentioned goal of the invention, the technical solution of the utility model realizes as follows:
The compressible filter of upward flow, it comprise draining tank and join with it by water inlet pipe, drainage goes out pipe and backflushing water intake pipe, the water circuit system that washback drainpipe is formed, but in draining tank, be equipped with the porous plate of barrier filtrate and the porous pressing plate of compressible filtrate, pressing plate is connected with its power transmission shaft that moves up and down of support, power transmission shaft is connected with the transmission mechanism that is fixed on the outer top of draining tank, its design feature is, described draining tank adopts the filter tank form, filtrate adopts soft filtrates such as fibrous nodules, water inlet pipe is located at the lower end of draining tank, and drainage goes out the upper end that pipe places draining tank.
According to above-mentioned technical scheme, the profile of described draining tank is rectangular cylinder or square column, is built up by steel or civil engineering batching commonly used.
According to above-mentioned technical scheme, in the described draining tank lower end, porous plate below be provided with the air diffuser that can connect source of the gas.
According to above-mentioned technical scheme, described transmission mechanism adopts the type of belt drive of worm gear, worm screw, adopts between porous pressing plate and the power transmission shaft linkage section to be threaded.
The utility model has adopted above-mentioned structure, and can make the direction of current in the whole drainage process is to move from bottom to top, has guaranteed that filtering accuracy can reach the level of micro-filtration membrane, and the rate of filtration also can be brought up to 80m/h.Because unit filter area water yield height, the utility model can replace the product with micro-filtrate membrane filtration fully.For the large-scale water processing filtering system of a plurality of filters of needs, each filter tank of the present utility model can be integrated and build up a big filter system, thereby reduce the floor space that equipment is installed.
Below in conjunction with accompanying drawing and concrete embodiment the utility model is described further.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is applied to the mounting arrangement figure of large-scale water treatment system for the utility model.
The specific embodiment
Referring to Fig. 1, the compressible filter of upward flow, what draining tank 1 adopted is the filter tank form, its profile is rectangular cylinder or square column, is built up by civil engineering batching commonly used.Filtrate adopts soft filtrates such as fibrous nodules, but in draining tank 1, be equipped with the porous plate 6 of barrier filtrate and the porous pressing plate 7 of compressible filtrate, porous pressing plate 7 is threaded with supporting to adopt between its power transmission shaft that moves up and down 8, power transmission shaft 8 is connected with the transmission mechanism 9 that is fixed on draining tank 1 outer top, what transmission mechanism 9 adopted is the type of belt drive of worm gear, worm screw, water inlet pipe 2 is located at the lower end of draining tank 1, drainage goes out the upper end that pipe 3 places draining tank 1, is provided with the air diffuser 10 that can connect source of the gas in draining tank 1 below lower end, the porous plate 6.
In order to be suitable for the demand of large-scale water treatment system, the pool wall of the utility model draining tank 1 can adopt reinforced concrete structure to build up and a plurality of draining tank 1 horizontally-arrangeds, vertical setting of types all are listed as, as shown in Figure 2.In the middle of two horizontally-arranged draining tanks 1, pipeline enclosure is set, is beneficial to the layout of upper and lower water route and valve, adopt this form to save area more than traditional a plurality of steel material pressure filter combinations.
When using the utility model, before normal filtration, transmission mechanism 9 starts, and drives porous pressing plate 7 and moves down certain size, compresses the filtering accuracy of soft filtrate to 1 μ m.Transmission mechanism 9 is shut down then, opens the valve that drainage goes out pipe 3 and water inlet pipe 2 and begins to filter, and is generally filter cycle 8-24 hour.When draining tank 1 loss of flood peak reached 5-10 rice, screening system began backwash.At this moment, close drainage and go out the valve of pipe 3 and water inlet pipe 2, open the valve of set washback drainpipe 5 that is connected with draining tank 1 and backflushing water intake pipe 4, transmission mechanism 9 starts makes porous pressing plate 7 be moved upward to desired location, starts the water pump that joins with backflushing water intake pipe 4 and carries out air-water backwashing 20min with air blast that air diffuser 10 joins.Leave standstill soft filtrate and make it sedimentation; close the valve of backflushing water intake pipe 4 at last; open the valve of water inlet pipe 2; starting transmission mechanism 9 makes porous pressing plate 7 move down certain size; compress the filtering accuracy of soft filtrate to 1 μ m, transmission mechanism 9 slows down and shuts down, and opens the valve that drainage goes out pipe 3; close the valve of washback drainpipe 5, recover normal filtration.
Whole filtration system can intermittent duty, also can move continuously.When intermittent duty, the draining tank 1 in several square filter tanks is by automatic or manual control carrying out simultaneously air-water backwashing; When taking to move continuously, the draining tank 1 in several square filter tanks can carry out air-water backwashing successively by automatic control system, and guarantees that the whole system treatment effeciency is constant, is that single pond rate of filtration suitably improves.
The utility model is equally applicable to the pressurized tank filtered version.
