Abstract
The utility model relates to a backwashing water filter with a hand controlled conversion type, composed of a main body, a hand drive part, a backwashing system, and a differential pressure display part. The utility model is used for treatment of industrial waste water or sewage. The hand drive part is provided with a screw rod and a rotating shaft, the backwashing system is provided with a nozzle scanner and a drain valve. When a filter cake deposited on a filter screen, the main body need cleaning. A hand wheel is screwed, diving the screw rod and the rotating shaft to rotate and rise, while the drain valve is opened, pressure difference is formed between the backwashing system and the filter screen, water flows reversely, and the filter cake on the filter screen is washed away. Owing to the hand controlled type, the utility model has the advantages of low product cost, easy maintenance, low water consumption of backwashing, and assurance of water usage of terminal users.
Description
The utility model belongs to the design and the manufacturing technology field of anti-filter rinsed.
Employed anti-filter rinsed in real work mostly adopts single net tube single suction to chew filter, many filter cores type filter etc. at present.Chew formula with regard to single suction, owing to have only a suction to chew,, just must strengthen and inhale the aperture area of chewing, strengthen cleaning arm volume and increase blowoff valve latus rectum for the online filter cake of cleaning and filtering effectively.So just cause complex structure, equipment volume increases, because need a large amount of filtered water to clean, can not guarantee terminal use's water again again.Many filter cores type filter is not because there is a transposer, thus need when cleaning cleaning arm to aim at hole below filter post again and again again, so waste time and energy.So these two kinds of products are very undesirable in actual production.
The purpose of this utility model provides a kind of simple in structure, and water consumption and crushing are little during anti-the cleaning, can guarantee the anti-rinse water filter of manual control shifting type of the normal water of terminal use when cleaning again.
Structure of the present utility model is as shown in drawings: by filter body, hand-drive part, back cleaning system and differential pressure display part constitute.Body (1) is cylindrical, and the upper and lower has end socket.End at body has inlet tube (7), and the other end has outlet (10).One mud hole (12) is arranged in the bottom of body, and an atmospheric valve (4) is arranged at body top.Respectively there is a toroidal membrane top and the bottom in body, have filter screen (9) on the dividing plate.Filter screen is cylindric.The top and the bottom of screen cloth are fixed on the lower clapboard respectively.The above is a main body structure.At the body pars intermedia one turning cylinder (6) is arranged, turning cylinder is a cavity structure.One leading screw (2) is arranged, at leading screw top suit one nut (3) above the turning cylinder.One handwheel (1) is arranged at the top of leading screw.This part is the hand-drive part.Have cleaning arm at the turning cylinder middle part, cleaning arm is a hollow-core construction, is connected with turning cylinder.The cleaning arm front end has to inhale chews scanner (8).It is a plurality of that scanner is chewed in suction, and staggered form is uniform up and down by equal angles around turning cylinder.Have a blowoff valve (13) below the turning cylinder.This part is described to be the back cleaning system structure.On the import and export pipe of body, have Pressure gauge (5).Pressure gauge is the pressure display part.
The utility model is used for the processing of industrial wastewater and sewage, during use is the inlet tube of this product and outlet to be connected on handle on the water water pipe and can work.This moment will be with air emptying in the body.Its method of work is: when water to be processed flows to body from inlet tube, thereby enter the inboard of filter screen, by the outside of pressure current to screen cloth, flow out by outlet again.Impurity in the water then is trapped within the filter screen inboard.When working long hours, accumulate in the cumulative formation filter cake of foreign material of screen pack inboard, the Pressure gauge on inlet tube and outlet can demonstrate pressure reduction like this.When reaching certain value, when influencing terminal use's water, just to clean filter cake.As long as turn handwheel during cleaning, drive leading screw and turning cylinder and rotate, this moment, turning cylinder rose under leading screw drives, below blowoff valve open automatically.Also drive to inhale and chew the scanner rotation.When blowoff valve one is opened, just in back cleaning system, form pressure differential, the state that is just that Water seeks its own level with the screen cloth outside.Like this, the water in the screen cloth outside will instead flow to inhale and chew in the scanner cavity.Clockwise again moving axis flows out along blowoff valve to still dirty.Simultaneously, the filter cake on the screen cloth just can be washed by the anti-water that flows and stream discharge downstream.Suction is chewed scanner with rising on the turning cylinder one circle ratio one circle highland.Filter cake on the screen cloth is also washed round and round.Form the form that transposition is cleaned.Treat that removing finishes, oppositely turn handwheel again, recover former duty again.
The utility model is simple in structure, and is reasonable in design, owing to adopt manual mode, under the situation that does not influence filter effect, greatly reduces product cost, and for ease of maintenaince, fault rate reduces greatly.Owing to adopt a plurality of suctions to chew scanner, make product realize miniaturization in addition.Overcome existing product big and big disadvantage of crushing of water consumption when anti-the cleaning again, guaranteed terminal use's water quality and quantity.
