Description
Technical field
The utility model relates to water filtration device, relates in particular to a kind of fabric filter in the water filtration device.
Background technology
At present; The most general water filtration device was a sand cylinder filter plant during water treatment was filtered, and its principle is to rely on the filtration layer of sand machinery interception in the cylinder body to remove suspended particulate substance in the water, but the dirt of tackling in the layer of sand is when too many; Pressure in the sand cylinder increases; Need this moment opening backwashing function, dirt is split away off from sand grains emit, thereby realize the function of layer of sand filtration, purification once more.The shortcoming of this sand cylinder filter plant: equipment size is big, and capital construction and installation cost are high; Unit filtering surface filtering traffic is less, and holding filth capacity is less; The filtered water loss is big, and operating cost is high, and is easy to generate " running husky " phenomenon; Need frequent backwash, backwashing time is long, and the backwash displacement is big; The backwash of sand cylinder generally needs more than 20 minutes, and backwash in 12 hours once; " waterpower sub-sieve " phenomenon can take place in sand grains after the backwash, and the heavy particle of bulky grain is sunken to the bottom, and the particle of granule light specific gravity is positioned at top, and so the sub-sieve order is unfavorable for that very layered filtration purifies.
Summary of the invention
In order to solve the problems of the prior art, the utility model provides a kind of fabric filter.
The utility model provides a kind of fabric filter; Comprise the filtration cavity, be provided with fibre filtering core in the said filtration cavity, the top of said filtration cavity is communicated with inlet pipeline; The bottom of said filtration cavity is communicated with outlet pipeline, and said filtration cavity is communicated with counter-flushing pipeline.
As the further improvement of the utility model, said inlet pipeline comprises main water inlet tube and the purification water inlet pipe that is communicated with said main water inlet tube, and said main water inlet tube is connected with water pump.
As the further improvement of the utility model, said outlet pipeline comprises and purifies water pipe that the said water pipe that purifies is provided with first valve.
As the further improvement of the utility model, said counter-flushing pipeline comprises backwash air inlet pipe that is communicated with the bottom of said filtration cavity and the backwash drainpipe that is communicated with the top of said filtration cavity.
As the further improvement of the utility model, said backwash drainpipe is communicated with blow-off pipe through second valve.
The beneficial effect of the utility model is: through such scheme, can filter through fibre filtering core, size is little, and cost is low; Unit filtering surface filtering traffic is more, and holding filth capacity is more; The filtered water loss is little, and operating cost is low, is not easy to produce " running husky " phenomenon; Do not need frequent backwash, backwashing time is short, and the backwash displacement is little; Helping layered filtration purifies.
Description of drawings
Fig. 1 is the structural representation of a kind of fabric filter of the utility model.
The specific embodiment
Below in conjunction with the description of drawings and the specific embodiment the utility model is further specified.
Drawing reference numeral among Fig. 1 is: water pump 1; Main water inlet tube 2; Purify water inlet pipe 3; Filter cavity 4; Fibre filtering core 41; Purify water pipe 5; Backwash drainpipe 6; Blow-off pipe 7; Backwash air inlet pipe 8.
As shown in Figure 1, a kind of fabric filter comprises and filters cavity 4; Be provided with fibre filtering core 41 in the said filtration cavity 4; The top of said filtration cavity 4 is communicated with inlet pipeline, and the bottom of said filtration cavity 4 is communicated with outlet pipeline, and said filtration cavity is communicated with counter-flushing pipeline.
As shown in Figure 1, said inlet pipeline comprises main water inlet tube 2 and the purification water inlet pipe 3 that is communicated with said main water inlet tube 2, and said main water inlet tube 2 is connected with water pump 1.
As shown in Figure 1, said outlet pipeline comprises and purifies water pipe 5 that the said water pipe 5 that purifies is provided with first valve.
As shown in Figure 1, said counter-flushing pipeline comprises backwash air inlet pipe 8 that is communicated with the bottom of said filtration cavity 4 and the backwash drainpipe 6 that is communicated with the top of said filtration cavity 4.
As shown in Figure 1, said backwash drainpipe 6 is communicated with blow-off pipe 7 through second valve.
A kind of fabric filter that the utility model provides; At first; Water inlet gets into fibre filtering core 41 through main water inlet tube 2, purification water inlet pipe 3 from the top of filtering cavity 4 through water pump 1 pressurization, the staple fibre of fibre filtering core 41 built-in uniquenesses, and Cheng Yousong is to tight array structure from top to bottom; Thereby oarse-grained suspension can be intercepted at the top of fibre filtering core 41; Short grained suspension is intercepted at the middle part and the bottom of fibre filtering core 41, thereby fully realizes the function that the whole district effectively filters, and the water behind fibre filtering core 41 effective filtration, purifications flows out from the water pipe 5 that purifies of the bottom of filtration cavity 4.
When the needs backwash, this moment is from filtering the top pressurization water inlet of cavity 4, simultaneously from the bottom through backwash air inlet pipe 8 air feed; Realize water, the common backwash of gas; So not only can significantly reduce the backwash water amount, and backwash effect is better, and for fibre filtering core 41; Because its structure is that to attend Panasonic tight; The dirt separation that then water, gas backwash are adhered to fiber more easily thoroughly from the bottom comes, and last backwashing water is discharged from the backwash drainpipe 6 at the top of filtering cavity 4, and the equipment that so guarantees is continuous, permanent possesses good filtration, purification function.
The advantage of a kind of fabric filter that the utility model provides is:
(1) equipment volume is little
Under equal filtering traffic situation, the floor space of fabric filter is about 1/4～1/10 of sand cylinder or other filter, and capital construction and installation cost greatly reduce.
(2) filter effect is better
The fabric filter retaining power is sand cylinder or other filter about 7 times, and filtering accuracy approximately improves an one magnitude.
(3) water, gas synergy are adopted in backwash, and washing time is short, water loss is few
The fabric filter backwash process is about 8 minutes, and backwash in about 2 days once.
(4) strainability is stable
Generally after using about half a year to one year, filter effect is degenerated rapidly for sand cylinder or other filter, causes that to filter water outlet not up to standard, and the fiber alignment structure of the built-in uniqueness of fabric filter can guarantee that the several years uses and property retention is stable.
(5) equipment life is long, easy and simple to handle.
Fabric filter approximately can reach 8～10 years projected life, and daily operation and maintenance is simple and convenient, and need not the professional and technical personnel can operate.
(6) the filtered water loss is little, and energy consumption is low.
The processing cost of ton water approximately is about 0.3 yuan.
Above content is the further explain that combines concrete preferred implementation that the utility model is done, and can not assert that the practical implementation of the utility model is confined to these explanations.For the those of ordinary skill of technical field under the utility model, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be regarded as belonging to the protection domain of the utility model.
