The automatic backwash filter of the pipeline-type rotary sieve comprises a shell, a cylindrical sieve, an electric device, a water inlet, a water outlet and a drain outlet, wherein the cylindrical sieve is arranged in the shell; the water inlet, the water outlet and the drain outlet are arranged on the shell; the drain outlet is connected with a drain valve; the electric device is connected with the shell through a connecting shaft; the other end of the connecting shaft passes through the cylindrical sieve and is connected with the shell; the section of the connecting shaft, which is located in the cylindrical sieve, is provided with a valve plate; both ends of the valve plate are connected with the cylindrical sieve; the water inlet and the water outlet are respectively arranged at both ends of the shell and are located at the equal height; and the drain outlet consists of a drain pipeline at one end of the cylindrical sieve. Under the condition that the normal operation of a flushing system of the rotary sieve is not influenced, the pipeline-type rotary sieve can be automatically cleaned by the automatic backwash filter of the pipeline-type rotary sieve. The automatic backwash filter of the pipeline-type rotary sieve is simple in structure, convenient in installation and low in production cost.
Description
Technical field
The present invention relates to automatic backwashing filter, relate in particular to the automatic backwashing filter of duct type rotary sieve.
Background technology
The water screen device is the common apparatus of the industrial department extensive uses such as generating, chemical industry, metallurgy, papermaking, wherein, rotary sieve is requisite drainage dirt cleaner in earth's surface, the thermal power plant water intaking runner, in recent years, in the industrial departments such as chemical industry, metallurgy, papermaking and city water, municipal sewage treatment field, also day by day adopt this equipment.
The interior impurity of certain limit in the current can be tackled and remove to rotary sieve effectively, and in use for some time, the screen pack of rotary sieve can be stopped up by impurity, when reaching certain chocking-up degree, must the foul on the wire side be cleaned.Because it is less to clean the shower nozzle aperture of flushing water system of web plate, shower nozzle is blocked up by dirt easily, in case and shower nozzle stops up, will cause the wire side in this shower nozzle flushing zone to can not get cleaning, thereby have influence on the filter capacity of equipment.
For preventing the generation of above-mentioned situation, common way is to add fixed filter before the flushing water system in the industry.In the prior art, a kind of scheme is to install Y-piece road formula manual filter additional, and (national standard number is another kind of scheme: JB/T10410-2004) in order to install the standard automatic backwashing filter additional.The shortcoming of such scheme is: front a kind of scheme adopts the manual type periodic cleaning, and labour intensity is large; Vertical auto-backwash filter screen in rear a kind of scheme employing standard, its structure is seen Fig. 1, comprise electric device 3 ＇, hand gear 11 ＇ are (when electric device 3 ＇ break down, can use hand gear 11 ＇), outer cylinder body 1 ＇ is (on minute, lower two cylindrical shells), the parts such as cup-strainer core 2 ＇ and base plate 12 ＇ form, the inside of cup-strainer core 2 ＇ is divided into eight equal parts, every five equilibrium is separated by dividing plate 13 ＇, there is eight/part to be connected with the blowdown steel pipe on base plate 12 ＇, described blowdown steel pipe forms sewage draining exit 6 ＇, this described linkage section communicates with the cavity of cup-strainer core 2 ＇, its complex structure, production cost is high, and water inlet 4 ＇ overhead the position is higher with delivery port 5 ＇, the while, the two was not at sustained height, so that occupation area of equipment is large, install complicated.
Summary of the invention
The applicant improves for above-mentioned shortcoming of the prior art, and a kind of automatic backwashing filter of duct type rotary sieve is provided, and it is simple in structure, and is easy for installation, and production cost is low.
Technical scheme of the present invention is as follows:
The automatic backwashing filter of duct type rotary sieve, comprise tubular filter screen, the electric device of shell, enclosure and water inlet, delivery port and the sewage draining exit that arranges at shell, the place is connected with blowoff valve at sewage draining exit, electric device is connected with shell by connecting axle, the connecting axle other end passes the tubular filter screen, and is connected with shell; Connecting axle in connecting axle and tubular filter screen is equipped with valve plate, and the valve plate two ends are connected with the tubular filter screen; Water inlet and delivery port are arranged on the two ends of shell, and are in sustained height; Sewage draining exit is made of the blow-off line of tubular filter screen one end.
Technique effect of the present invention:
The present invention can be in the situation that does not affect the normal operation of main equipment by the design of valve plate and blowoff valve, the web plate of automatic pipe blow-through formula rotary sieve, and it is simple in structure, and production cost is low, and saves human and material resources; Water inlet and delivery port overhead position are higher, and the two is in sustained height, can realize that duct type installs, and easy for installation.

Fig. 2 is structural representation of the present invention and filters working state figure.
Fig. 3 is backwash working state figure of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
See Fig. 2, Fig. 3, the present invention includes tubular filter screen 2, the electric device 3 of shell 1, shell 1 inside and water inlet 4, delivery port 5 and the sewage draining exit 6 that arranges at shell 1,6 places are connected with blowoff valve 9 at sewage draining exit, electric device 3 adopts standard electromotor, electric device 3 is connected with shell 1 by connecting axle 7, connecting axle 7 other ends pass tubular filter screen 2, and are connected with shell 1; With the shaft part that is connected in the tubular filter screen 2 valve plate 8 is housed at connecting axle 7, valve plate 8 two ends are connected with tubular filter screen 2, and valve plate 8 is with the circular arc plate face that matches with tubular filter screen 2 inwalls; Water inlet 4 is arranged on the two ends of shell 1 with delivery port 5, and is in sustained height, all is connected with flange 10 at water inlet 4 with delivery port 5 places; Sewage draining exit 6 is made of the blow-off line of tubular filter screen 2 one ends.
The method of operation of the present invention is as follows:
(1) the filtration course of work of the present invention: see Fig. 2, when the present invention filters work, blowoff valve 9 cuts out, electric device 3 drives valve plate 8 rotations, and valve plate 8 rotations are parallel with the water (flow) direction that enters to its circular arc plate face, and this moment, valve plate 8 was in opening, current enter tubular filter screen 2 by water inlet 4, outside from the self-filtering of tubular filter screen 2 to tubular filter screen 2, and flow to shower nozzle in the outside flushing water system through delivery port 5, water (flow) direction is shown in Fig. 1 direction of arrow.
