Abstract
The utility model relates to an automatic cleaning filter with two-level filter type, which is used for automatic filtration and removal of impurities in the waste water and other liquids in a water treatment system for environmental protection and production process, thereby ensuring the safe operation of the main equipments. The novel automatic cleaning filter with two-level filter type consists of an electric motor reducer 1, an exhaust valve 2, an end cover 3, a backwash suction nozzle 4, a precision filter element 5, a sewage inlet orifice 6, a water diversion plate 7, a rough filter element 8, an automatic drain valve 9, a hand hole 10, a coupling 11, a hollow shaft 12, a lift lug 13, a clean water outlet orifice 14, a cabinet 15, as well as a differential pressure detection nozzle 16. Being different from the earlier self-cleaning filter with single cylinder, the utility model additionally addes the water diversion plate, the rough filter element and the hand hole, one end of the water diversion plate is connected with the rough filter element, the other end is connected with the sewage inlet orifice, and the rough filter element and the hand hole are arranged at the bottom part of the filter. The utility model can ensure the precision filter element to safely and automatically work for long-term without being damaged.
Description
Technical field
The utility model relates in a kind of environmental protection and the production technology water treatment system, and the automatic fitration that is used for other liquid impurity of waste water is removed, thereby can guarantee the double-stage filtering formula automatic cleaning strainer of main equipment safe operation.
Background technology
The monotubular self-cleaning filter of innovation and creation before the applicant because this kind filter adopts single-stage to filter, promptly only has the smart filter core of a cover in the filter, directly sewage or liquid are carried out disposable filtering.The shortcoming of this filtration is: 1, the backwash suction nozzle is little during smart the filtration, and filtering accuracy is high more, and the suction nozzle hole is more little, can't suck suction nozzle when the backwash and excretes greater than the big impurity of suction nozzle hole, and can cause filtering element (cartridge) to scratch or damage.2, since the treatment sewage pipeline construction may the more residual bulk that is not eliminated kill matter, as: rubble, brick, welding rod, metal stub bar or timber etc., these assorted greatly pieces enter and are easy to cause the backwash arm can't backwash and damage in the filter.3, the single-stage self-cleaning filter is fragile, reliability is low, safety inadequately.
The utility model content
The technical problems to be solved in the utility model is by designing a kind of double-stage filtering formula automatic cleaning strainer thick, the segmentation worker that has.Firm coarse filtration macropore filter core only plays interception function to big impurity and block foreign material, and smart the filtration is the final filtration that has the self-cleaning function.Generally speaking, because block bigger material is few, be simplified structure and security needs, self-cleaning mechanism is not established in coarse filtration, gets final product and only establish labor cleaning's hand hole.This double-stage filtering formula automatic cleaning strainer has overcome the shortcoming of original self-cleaning filter, becomes a kind of novel double-stage filtering formula automatic cleaning strainer that guarantees that the automatic work of smart filter core long-term safety does not damage.
In order to solve the problems of the technologies described above, the utility model design is a kind of by motor reducer, air bleeding valve, end cap, the backwash suction nozzle, smart filtering element (cartridge), sewage is gone into the mouth of pipe, weather board, the coarse filtration heart, automatic blowdown valve, hand hole, shaft coupling, hollow shaft, hanger, the water purification outlet spout, casing, differential pressure detects the novel double-stage filtering formula automatic cleaning strainer that the mouth of pipe is formed, different with monotubular self-cleaning filter before this is: set up weather board, the coarse filtration heart and hand hole, be connected with the coarse filtration heart at described weather board one end, the other end is gone into the mouth of pipe with sewage and is connected, and the coarse filtration heart and hand hole are arranged on the bottom of filter.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
Fig. 1 is the structural representation of novel double-stage filtering formula automatic cleaning strainer.
Situation when Fig. 2 is the smart filtered water stream of the utility model and backwash water filtration and work
Fig. 3 is the filtration of the utility model coarse filtration current and the situation in when work
The specific embodiment
Fig. 1 is the structural representation of novel double-stage filtering formula automatic cleaning strainer.Comprise that motor reducer 1, air bleeding valve 2, end cap 3, backwash suction nozzle 4, smart filtering element (cartridge) 5, sewage goes into the mouth of pipe 6, weather board 7, the coarse filtration heart 8, automatic blowdown valve 9, hand hole 10, shaft coupling 11, hollow shaft 12, hanger 13, water purification outlet spout 14, casing 15, differential pressure and detect the mouth of pipe 16.
The utility model is a kind of double-stage filtering formula automatic cleaning strainer, promptly in same filter compact design thick and smart double-filtration.Its working condition is such, in filtering casing 15 middle and upper parts smart filtering element (cartridge) 5 is housed, and the coarse filtration heart 8 is equipped with in the bottom, and backwash suction nozzle 4 is housed on the hollow shaft 12.During normal filtration, sewage is gone into the mouth of pipe 6 by the sewage on right side and is entered filter, weather board 7 one ends are gone into the mouth of pipe 6 with sewage and are connected, the other end is connected with the coarse filtration heart 8, by weather board 7 the sewage conductance is entered the coarse filtration heart 8 inboards and rises to smart filtering element (cartridge) 5 inboards to the lower end, the water purification of filtering through essence flows out by water purification outlet spout 14 at last.When reaching setting value by the both sides differential pressure detection mouth of pipe 16 detected differential pressures, differential pressure switch just starts filter backwash automatically: motor reducer 1 drives hollow shaft 12 and backwash suction nozzle 4 by shaft coupling 11, simultaneously, automatic blowdown valve 9 makes backwash suction nozzle 4 generation negative pressure because opening, and will be attached to sucking-off of little foreign material particle and the blowdown on smart filtering element (cartridge) 5 inwalls in rotation.The self-cleaning process continued 1-2 minute or owing to the differential pressure return, then self-cleaning finishes.In operation process, filter is when backwash, and except that nearby the smart filtering element (cartridge) 5 of small size is backwash mutually with backwash suction nozzle 4, the smart filtering element (cartridge) 5 of its large tracts of land is still keeping the normal filtration state.Foreign material thick in the sewage are few, consider security of operation, and backwashing mechanism is not established in coarse filtration, and only establishes hand hole 10 in the bottom, and general needs regularly to open hand hole 10 cleanings at initial operating stage and get final product for several times.Get rid of gas in the filter when in addition, air bleeding valve 2 is used for the operation beginning among Fig. 1.End cap 3 and hanger 13 are used for dismounting.When this filter is horizontal work, sewage should be gone into the mouth of pipe 6 and move to the 6a place, air bleeding valve 2 moves to the 2a place, and hand hole 10 moves to the 10a place and gets final product.
Situation when Fig. 2 is the smart filtered water stream of the utility model and backwash water filtration and work
Fig. 3 is the filtration of the utility model coarse filtration current and the situation in when work
In sum, adopt the utility model double-stage filtering formula automatic cleaning strainer, can guarantee that the automatic work of smart filter core long-term safety does not damage.
