Fully automatic cleaning filter of the present utility model is widely used in fields such as metallurgy, electric power, petrochemical industry, environmental protection, agricultural water conservancy, is adapted to recirculated water especially and uses, and clean water supplies water, municipal middle water, river water cleaning utilization, and place such as field irrigation.
Description of drawings
Fig. 1 is the structural representation of a kind of fully automatic cleaning filter of the present utility model.
Fig. 2 is the scheme of installation of Fig. 1 filter.
The specific embodiment
Referring to Fig. 1, the utility model is a kind of fully automatic cleaning filter, and it mainly is made up of casing 1, net-filter assembly 2, sewage suction device 3, collecting sewage room 4, rotary motor 5, blowdown apparatus 6, hydroman 7, water inlet pipe 8 and outlet pipe 9.
Casing 1 is the cylindrical shell shape, and casing 1 links to each other with outlet pipe 9 with water inlet pipe 8.Casing 1 is the critical piece of filter, and casing 1 is generally made by the low-carbon (LC) steel.Casing is selected the low-carbon (LC) steel for use, mainly is in order to guarantee product strength and weldability preferably.Casing 1 inner surface and outer surface spraying epoxy polyester material can guarantee that product prevents the casing corrosion under abominable condition of water quality, and the succinct light in casing surface, are convenient to cleaning.Casing 1 is provided with and is used to the movable hand hole that overhauls and maintain, is convenient to operation.The potted component of casing 1 all adopts the oil resistant rubber goods, its good airproof performance, long service life.Position of centre of gravity is provided with suspension ring 11 at the top of casing 1, so that the product lifting is moved.Casing can be made into 1.0MPa, 1.6MPa, three pressure ratings of 2.5MPa by the different product demand.As special requirement, can customize casing separately.
Net-filter assembly 2 is core components of filter.Net-filter assembly 2 is made up of cylindrical shell skeleton, coarse strainer 21 and fie screen 22.The cylindrical shell skeleton is the plastic cylinder skeleton, and the cylindrical shell skeleton especially selects for use engineering plastics to make.Filter screen can be divided into plain net, seat type net, Z type net etc. by different filtering waters and requirement; Filter screen can be selected in 50～3000 micrometer ranges by different filtering accuracies.The coarse strainer of net-filter assembly and fie screen are made by the stainless acid resistant steel material.The filter screen material is all selected stainless acid resistant steel for use, can guarantee intensity that filter screen is enough and durable in use.Filter screen and plastic cylinder skeleton melt technology by high frequency induction thermal, make filter screen and plastic cylinder skeleton strong bonded, guarantee that filter screen does not deform in long-time, aliquation, situation such as come off.Net-filter assembly 2 is placed in the casing 1, and central dividing plate 10 is installed between net-filter assembly 2 and casing 1.
Collecting sewage room 4 is positioned at the rear portion of sewage suction device 3, and collecting sewage room 4 is positioned at casing 1 rear portion simultaneously, and as shown in fig. 1, the rear portion of collecting sewage room 4 in casing 1 formed every putting by rear bulkhead 13.
Hydroman 7 is precise parts of filter.Hydroman 7 is installed in casing 1 outside.Hydroman mainly is that water inlet and the delivery port pressure of accepting filter change, and pressure signal is fed back to the function corresponding element; Simultaneously, hydroman is again a pilot valve of opening blowdown apparatus, and when water inlet, discharge pressure difference reached setting value, the signal of control system was transferred in the blowoff valve, and blowoff valve is opened, thereby finishes the dirt eliminating function of filter; When the Inlet and outlet water pressure differential disappeared, hydroman was a blowoff valve transmission shutdown signal, thereby blowoff valve cuts out.
The course of work of fully automatic cleaning filter of the present utility model is as follows:
After sewage enters cartridge filter, the impurity dirt is tackled by the filter screen on the cylindrical shell and attached on the cylindrical shell filter screen inwall, when the impurity dirt builds up when inwall has influence on filtering traffic, also just form the pressure differential of water inlet end and water side gradually, when pressure differential reaches predetermined value, hydroman is opened blowoff valve automatically, blowoff valve is with after atmosphere communicates, intrasystem water under high pressure will flow to atmosphere along dirt sucking tube, this moment, the dirt sucking tube internal pressure sharply descended, pollution-absorbing nozzle produces very strong flushing current simultaneously, this pressure drop phenomena makes pollution-absorbing nozzle form a strong suction, thereby guarantee that the impurity dirt that pollution-absorbing nozzle will abut in the filter screen inwall develops, and outside dirt sucking tube discharge machine.In the strong suction drainage procedure, the hydraulic motors that is installed on the dirt sucking tube leans on the reaction force of water to form the curve rotation, simultaneously, be positioned at the fluid-operated piston moving linearly of dirt sucking tube afterbody, form pollution-absorbing nozzle shape is rotating in the shape of a spiral and suck motion, thereby guarantee that the every bit in the filter screen can both get effective washing.After finishing a cleaning blowdown process, water inlet end and water side pressure balance, the sewage suction device homing enters another working cycles process again.
Referring to Fig. 2, the mounting means of fully automatic cleaning filter of the present utility model is as follows:
The water inlet pipe 8 and the outlet pipe 9 of filter are installed on the sewage conduct 14, and water inlet pipe 8 is connected water inlet dish valve 15 and water outlet dish valve 16 respectively with outlet pipe 9, and sewage conduct dish valve 17 is being installed on the sewage conduct 14 between water inlet pipe 8 and the outlet pipe 9.When if there is water hammer in system or might backwater phenomenon occurs, on the sewage conduct 14 that is positioned at outlet pipe 9 back, check-valves 18 must be installed.
Certainly, those skilled in the art in the present technique field will be appreciated that, the foregoing description only is to be used for illustrating the utility model, and be not with opposing qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in the scope of the utility model claim conversion, the modification of the foregoing description.
