Abstract
The invention discloses a five-inch torpedo desanding screen type fully-automatic flushing filter. A cylindrical filter screen, of which the two ends are provided with sealing rings, are mounted at the internal two ends of a tank body through an annular seat and a cover seat, a plastic torpedo screen core is mounted in the filter screen through the cover seat with a drain valve, the front end of the tank body and a water inlet pipe with a high-pressure water intaking hole are integrated through hard connection, the tank body is arranged parallelly, a water outlet pipe with a vertical short pipe and a low-pressure water intaking hole is in soft connection with the tank body through a butterfly valve, and the drain valve of the cover seat is connected to an automatic control system with an electromagnetic head through a water control pipe. According to the five-inch torpedo desanding screen type fully-automatic flushing filter, an automatic cleaning function is achieved, manual operation is not required, the labor intensity is low, the efficiency is high, the change of overflowing boundary conditions is little, the loss of water head is low, energy is saved, the parallel backwashing mode is changed into a single direct flushing mode, the material and annual operation management costs are reduced, and conditions are established and created for filtering stations of contiguous-managed irrigation systems and centralized-managed head systems.
Description
Technical field
The invention belongs to industry and agricultural water conservation defecator, particularly 5 cun of torpedo desanding net formula full-automatic flushing filters.
Background technology
At present in the Treatment of Industrial Water progressively promoted and water-saving irrigation, as waterworks water processes and drip irrigation, the water quality requirement of domestic water and irrigation water is higher, it is necessary to filtered out the impurity in water and silt in advance by filter, in case drip irrigation zone blocks and reaches domestic water standard.The filter that tradition uses is Manual-cleaning well strainer and automatically cleans filter with washing screen, has that monomer uses and used in parallel.Monomer Manual-cleaning well strainer such as filter net jam, when current are not smooth, stops supplying water, carries out manual cleaning, and impact runs well.When manual well strainer used in parallel needs to clean in the course of the work, can first cutting off a well strainer and be carried out, other well strainers are operated, successively Manual-cleaning in turn；Inflow-rate of water turbine can be reduced, reduce work efficiency, time-consuming.Although automatic cleaning screen filter can realize automatically cleaning filter screen, but owing to all being formed by several monomer well strainer parallel combinations, ingredient is many, and volume is big, cross hydrophily body changeable, the loss of flood peak is big, and corresponding power plant power is big, and operating cost is high, consumptive material, uneconomical, and backwash needs filtered clean water, strengthens leaching requirement and processing additional-energy thereof.As a result, causing that application is undesirable, the superiority of water-saving irrigation technique does not well embody, and popularizes and slowly waits series of problems.
Summary of the invention
It is an object of the invention to provide a kind of 5 cun of torpedo desanding net formula full-automatic flushing filters, automatic cleaning function can be realized, need not manual operation, labor intensity is low, and efficiency is high, crosses stream boundary condition with low uncertainty, the loss of flood peak is little and energy-conservation, backwash mode in parallel changes monomer into and flings and wash, and saves material and year operational management expense, and the stem system filter station for the irrigation system managed in flakes and centralized management creates conditions simultaneously.
The object of the present invention is achieved like this: a kind of 5 cun of torpedo desanding net formula full-automatic flushing filters, including with water inlet pipe, with the drainage screen of torpedo web-roll core and ring seat thereof in the cage of the tank body of outlet pipe and in addition blowoff valve and tank body, it is characterized in that: in tank body, one end and the other end are installed with the two cylindrical filter net with sealing ring by ring seat and cage, by being installed with plastic fish Thunder Network core with the cage of blowoff valve in drainage screen, the front one end of tank body and the water inlet pipe with high pressure water intaking hole, integration is formed by Hard link, tank body and tank body are arranged in parallel, with vertical short tube, the outlet pipe in low pressure water intaking hole, realize being flexible coupling by butterfly valve.It addition, the water inlet pipe of tank body one end is water source water supply use, the other end cage with blowoff valve covers, and for sewage effluent, the blowoff valve on cage is connected to Electrical heads at interior automatic control system by water control pipe.
The operation principle of the present invention is: enter from water inlet when the water containing impurity between drainage screen and its torpedo filter element in tank body filter chamber in, water containing impurity from the inwall of drainage screen enter from outer wall flow out time, impurity is then attached on drainage screen inwall, and clean water then flows out from the outer wall of drainage screen.When on inwall, attachment dirt is more, in filter, exocoel produces certain pressure reduction, when pressure reduction reaches preset value, information is passed to controller by the differential pressure pickup of automatic control system, now controller will start Electrical heads according to instruction, blowoff valve is opened, now, the pressured poor reflux of part water of drainage screen outer wall enters into drainage screen inwall, the dirt being adsorbed on inwall is forced to come off, and rely on tank body import the high-speed punching brushing force of confession be flushed to and go out, when washing time reaches preset value, controller instruction Electrical heads closes blowoff valve, terminate blowdown, filter enters normal operating conditions.It is high that the present invention realizes automatic cleaning strainer automaticity, it is not necessary to being equipped with special messenger, only need little water yield and relatively low hydraulic pressure during cleaning, scavenging period is short, and the normal operation of not influential system when cleaning.Filter is uninterrupted normal water supply when cleaning, and the self-cleaning time only needs 20 40 seconds, and normal water supply is not affected.The method controlled can be diversification, and electric-control board can meet various requirement: controlled pressure reduction or time are carried out, and wash number realizes memory and other function.
Present invention achieves automatic cleaning function, need not manual operation, labor intensity is low, efficiency is high, crossing stream boundary condition with low uncertainty, the loss of flood peak is little and energy-conservation, and backwash mode in parallel changes monomer into and flings and wash, saving material and year operational management expense, the foundation for the irrigation system managed in flakes and the stem system filter station of centralized management simultaneously creates conditions.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described.
Fig. 1 is the main TV structure schematic diagram of the present invention.
