Abstract
The utility model relates to a self-suction vertical filter comprising a filter casing, a meshwork filter element, a water inlet, a water outlet, a blow-off pipe, a sewage suction pipe, a cleaning head and an automatic cleaning control device. The utility model is characterized in that: the meshwork filter element is divided into a coarse strainer and a fine strainer, wherein the coarse strainer is horizontally arranged at the water inlet end at the upper side of the fine strainer, the contact surface of the cleaning head and the fine strainer is provided with an arc surface matched with the surface of the fine strainer, the blow-off pipe is provided with a valve, the sewage suction pipe is provided with a motor, and a gearing, a connecting rod and a reducer are arranged between the sewage suction pipe and the motor. Compared with the prior art, because the blow-off pipe rotates through mechanical transmission, the self-suction vertical filter has reliable, steady and constant transmission; because the water inlet is arranged at the upper side and the reducer and the motor are arranged at the side surface through taper gears and the connecting rod, the self-suction vertical filter is convenient to operate and maintain and has a reasonable structure; because the arc surface arranged at the contact surface of the cleaning head and the fine strainer, the self-suction vertical filter has excellent sewage suction effect and small water consumption for sewage discharge.
Description
Technical field:
The utility model relates to a kind of self-priming vertical filter.
Background technology:
At present because the feedback of water resource is general, the scope that technology such as drip irrigation and spray irrigation are used more and more widely, well strainer can dispose the filter screen in different apertures according to actual needs arbitrarily and realize different filtration requirements, but the silt that well strainer in use filters out need carry out frequent clean and influence result of use.
Chinese patent CN2817950Y discloses a kind of full-automatic self-cleaning filter, mainly by filter housing, cylindrical net formula is crossed filter core, water inlet, delivery port, soil chamber, outlet of sewer and cleaning device, described soil chamber and cylindrical net formula are crossed and are divided into two cavitys between the filter core, cylindrical net formula is filtered in-core and is axially arranged with the self-cleaning axle, this self-cleaning axle central shaft is to being tubulose, on axis body, be provided with several and clean suction nozzle, the suction nozzle mouth is pressed close to the net formula and is filtered the in-core wall, one end of self-cleaning axle is provided with sewage outlet, this sewage outlet is located in the soil chamber, on the self-cleaning axle, be provided with the drive unit hydraulic motor that can make the rotation of self-cleaning axle, and the drive unit hydraulic piston that the self-cleaning axle is axially moved back and forth.And this full-automatic self-cleaning filter, dirt sucking tube is done radially in the soil pick-up process and is rotatablely moved, the velocity of rotation instability, speed is with change in pressure, the big velocity of rotation of pressure is fast, soil pick-up is not thorough, the phenomenon that the little velocity of rotation of pressure is slow or the appearance commentaries on classics is motionless, carry out blowdown and have only driving by force to close delivery port, the soil pick-up effect is undesirable, and suction nozzle is cylindrical, the diameter of thin screen pack is very big and the suction nozzle diameter is less, the soil pick-up weak effect, the blowdown water consumption is also big, opens sewage draining exit when closing delivery port, because the caliber of sewage draining exit is very little, the phenomenon that tank body short time internal pressure raises can occur, and it is excessive to form the blowdown water consumption, the phenomenon of underground pipe network instability of flow.
Summary of the invention:
The purpose of this utility model is to provide a kind of machine driving reliable, rational in infrastructure, and soil pick-up is respond well, the self-priming vertical filter that the blowdown water consumption is little.
The utility model comprises that filter housings, net formula cross filter core, water inlet, delivery port, blow-off pipe, dirt sucking tube, cleaning head and clean automaton, it is characterized in that the net formula crosses filter core and be divided into coarse strainer and fie screen, coarse strainer laterally is located at fie screen top inlet end, the contact-making surface of described cleaning head and fie screen is provided with the cambered surface that matches with thin net, establish valve on the blow-off pipe, dirt sucking tube is provided with motor, is provided with transmission device, connecting rod and reductor between described dirt sucking tube and the motor.
Above-mentioned transmission device is the taper travelling gear, also can be worm gear and worm screw.
For making cost of the present utility model lower, easier operation and easy and simple to handle during use, the valve on the dirt sucking tube described in the utility model is preferably electric butterfly valve.
The course of work of the present utility model: water can block big dirt by coarse filtration from water inlet, and general obstruction needs operation for a long time, can reflect by pressure reduction if stop up, the excessive sewage draining exit of opening of pressure reduction cleans, extract coarse strainer out and clean, reinstall after clean, recover operate as normal.The cleaning process of fie screen is that the water through entering fie screen inside after the coarse filtration is blocked in dirt on the fie screen inwall, along with deposit on the growth inwall of time is more and more, it is poor to form the fine-structure mesh external and internal pressure, when pressure differential reaches the set value of differential pressure controller, need the dirt on the inwall is carried out backwash, the pressure reduction of electric control box or time control simultaneously starts, motor rotating band dynamic cycloid pin gear speed reducer, connecting rod, bevel gear rotates dirt sucking tube, rotating all suction nozzles blots the dirt on the fie screen wall only, it is normal that pressure reduction recovers, motor stops operating, and electronic blowdown butterfly valve slowly cuts out.
Compared with prior art, the utility model is because the rotation of blow-off pipe is by machine driving, reliable transmission, stable, average rate are also because water inlet is located at top, reductor and motor are located at the side by angular wheel and connecting rod, Operation and maintenance are convenient, and are rational in infrastructure, also because cleaning head and fine filtering wire side have the cambered surface that matches, soil pick-up is effective, and the blowdown water consumption is little.
