Technical field
The utility model relates to automatic backwashing filter, relates 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.
The utility model content
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.
The technical solution of the utility model 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 utility model:
The utility model 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.
