Description
Technical field
The present invention relates to filtering technique, specifically a kind of online ingredients, automatic backwash filter.
Background technology
Existing filter kind is a lot, has filter (as Germany, the U.S., Israel etc.) most of price comparisons expensive (every cover price 300,000～2,000,000 dollars) of recoil function.General filtration device structure is whole cartridge type jar, and a filter is set in it, in order to increase filter area, adopts the way of lengthening filter screen path (as: the tortuous setting), and structure is complicated; Recoil by shutting down the change flow direction during flushing; but the dirt that remains in filter screen is difficult to discharge, and have to shut down and overhaul, thereby influence normally carrying out of work; owing to overhaul filter more complicated commonly used; the staff that then needs who has enters a jar interior cleaning, visible poor working environment, and the cleaning difficulty is big; downtime is long; maintenance operating cost height in addition can not online ingredients, thereby perplexs the normal promotion and application of filter always.
Summary of the invention
For the deficiency that overcomes that above-mentioned shutdown overhauls that efficient is low, the cleaning difficulty is big and can not online ingredients, the purpose of this invention is to provide a kind of efficient, easily maintenance, can the clean aqua of online interpolation water purification, the filter of online (not shutting down) automatic backwash.
To achieve these goals, technical scheme of the present invention is: comprise tank body, filter screen, filter screen is installed in tank body; Tank body is a split-type structural, by forming in dust cover, main body, a jar end, every dish, lower partitioning disk tank body is divided into three parts by last, wherein: the main center place is provided with a tubing string, welds every dish with upper and lower, and the tubing string sidewall is provided with ingredients and uses the group hole, described filter screen is distributed in the tubing string periphery, goes up in main body between the lower partitioning disk, the input pipe that communicates with hopper penetrates from the cover cap top, and the centre bore by upper spacer communicates with the tubing string upper end, and the cover cap opener links together dust cover and main body; In the cavity at the bottom of the jar, be tubular structure by motor-driven back washing disc, its upper end is positioned below, tubing string and lower partitioning disk middle part, bottom at the bottom of its lower end is installed in jar, to tank body, and other establishes a pivoted arm by circular hole on the lower partitioning disk and the dynamic sealing-in of filter screen; Establish water inlet at the jar downside wall, above main body wall, set out the mouth of a river;
Described ingredients is with establishing magnetic valve on the input pipe; Install on the input pipe of movable joint outside cover cap; Described opener comprises hydraulic cylinder, pulling force lever, bearing, and wherein: hydraulic cylinder one end is connected on the main body wall, and an end of the other end and pulling force lever joins, and the lever other end and cover cap are connected, and the middle part is hinged at the fulcrum place with the bearing that is installed on the main body; Filter screen links together by differential and upper spacer last in the described main body, be installed together down by skeleton and lower clapboard, on lower clapboard, with the perforate of filter screen installation part;
Bottom and extending outside the tank body at the bottom of described backwash rotating disk is installed in jar by mount pad B, establish blowoff valve or manually-operated gate on the part outside at the bottom of extending jar, backwash rotating disk sidewall is connected and nibbles wheel greatly, installs on the output shaft of motor and nibbles wheel for a short time, at the bottom of nibbling wheel greatly and nibbling wheel for a short time and be engaged in jar in the cavity; On at the bottom of motor output shaft is installed in jar by mount pad A; Other establish armature is installed rotating disk on the output shaft of motor, bottom outer wall at the bottom of bottom outer wall at the bottom of jar, position controlling switch are installed in jar, its position is corresponding at the volley with armature; Be provided with sealing ring between the output shaft of described motor and mount pad A, backwash rotating disk and mount pad B, filter screen and the skeleton; The quantity of described filter screen is 2～12, is distributed in going up between dish, lower partitioning disk in the main body; The number of described armature is identical with the filter screen number, is distributed on the rotating disk; Described gauge tap can be and connects switch, common travel switch or microswitch; Add handle in described cap side walls.
Compared with prior art, the present invention has more following advantage:
1. cost is low, high efficiency.The present invention has changed traditional whole jar core structure, upper top cover has been made into to open at any time, dust cover structure, can open fast and easily and change filter screen and inner the cleaning, shortened the maintenance interval, save maintenance cost 30%～50%; In addition, adopt the multicore filter structure, the large tracts of land exchange, its flow resistance is little, filter efficiency height, water treatment amount are 10～200 tons/h, improve 3～10 times of work efficiency, but again because Hand scarf, can save operation and maintenance cost greatly, can save a large amount of raw material, and then reduce cost, increase economic efficiency the not enough import equipment 1/10th～30 of its cost.
2. simple in structure, intensity is reliable.The present invention adds the thick-wall seamless tubing string with group hole in tank body, weld every dish with upper and lower, make upper and lower every the dish compression strength be multiplied, and welding processing is convenient, and rational in infrastructure, technology is simple, can improve speed of production, guarantee the quality of product again.
3. be convenient to cleaning.The present invention has adopted center antipriming pipe rod structure, major function by magnetic valve causes in thick-wall seamless tubing string through the additive input pipe additive, the liquid that flows out from the group hole and finish through screen filtration evenly mixes, uninterrupted streamlined production process is added in the realization automatic control, solve clean continuously, the clean aqueous process streams water conservancy project skill of automatic control from structure, dissolved a difficult problem that runs in the cleaning in the prior art.
4. long service life.Because filter of the present invention adopts many filter cartridge constructions, thereby flow resistance is little, water inlet, delivery port mounting structure go out on advancing under being, the utilization dirt of its pipeline structure science principle at the bottom of being deposited on naturally under the quiet slow condition of pressure reduction jar that minces has effectively prolonged service life of filter screen when having improved filter efficiency.
5. the present invention is the change on filtration device structure, has wide economic benefit and application prospect.
