Specific embodiment
The utility model is further illustrated with reference to the accompanying drawings and examples.
As shown in figure 1, the filter with scratch device, including tank body 1, liquid feed valve 2, the liquid feed valve 2 is under tank body 1
Portion, also including screen pipe 3, filtrate conduit 4, water pump 5 and scratch device, the top of the tank body 1 and bottom are provided with opening, the tank
The open top of body 1 penetrates filtrate conduit 4 and fixed, the top of the penetrating end of the filtrate conduit 4 connection screen pipe 3, connects in outer one end
Water pump 5, described scratch device one end is sheathed on the outer surface of screen pipe 3 and the other end passes the bottom opening of tank body 1.
Such scheme is main scheme for implementing said method, the bottom of tank body 1 arrange liquid feed valve 2 solution is entered in tank and it is slow on
Required water level is increased to, up and down place is provided with opening to tank body；For solution filtration in tank, the top surface of screen pipe 3 connects filter to screen pipe 3
Liquid pipe road 4, the external connection water pump of filtrate conduit 4 so drives water pump to evacuate, and forms pressure differential so as to realize solution after filtering
Extract out from filtrate conduit 4；After work a period of time, larger particles will form a metafiltration cake on the surface of screen pipe 3 to be affected to filter
Process, is at this moment set in the scratch device of the outer surface of screen pipe 3 by rotation, and then removes the filter cake of attachment so that filter into
Cheng Jixu.In view of the reasonability of scratch device, its one end is sheathed on into the outer surface of screen pipe 3, one end passes the bottom of tank body 1 and opens
Mouth is easy to rotation process.
The scratch device can be that a simple scraper plate and a spin axis are combined, it would however also be possible to employ brush class formation coordinates
Bent axle is realized, and the present embodiment adopts concrete scheme：The scratch device includes fixed mount 8, cock 9, some scraper plates 6 and fixation
Ring 7, the scraper plate 6 scrapes point and is close to the outer surface of screen pipe 3, and it is scraped the back of the body and is connected on the inner ring of retainer ring 7, and the retainer ring 7 connects
The one end of fixed mount 8 is connect, the connection cock 9 of the other end of the fixed mount 8 is fitted in the middle part of the cock 9 with the bottom opening of tank body 1.This
Scheme scrapes efficiency high, and using scraping is rotated back and forth attachment filter cake can be effectively removed；Scraper plate 6 is close to the outer surface of screen pipe 3, can
The blocked up accumulation of filter cake is effectively prevented at the place of being close to, it is scraped the back of the body ring 7 that is connected and multiple scraper plates 6 can be arranged on ring transports jointly
It is dynamic；Connected by fixed mount 8 between retainer ring 7 and cock 9, cock 9 fitted and is sealed on the bottom opening of tank body 1,
Once rotation cock 9, fixed mount 8 drives retainer ring 7 so as to the rotation for realizing scraper plate 6 is scraped.
Cock 9 can be that simple plunger seals, but act on material leakage while also to realize rotating, then described
Cock 9 includes big footpath section and path section, and the big footpath section is located on path section and is revolved using screw thread with the bottom opening of tank body 1
Close.Big footpath section adopts threaded engagement with bottom opening, and the rotation for realizing scraper plate 6 is scraped, while the big footpath section lower section of cock 9 is path
Section, it is ensured that big footpath section is screwed in can also be by fixed path section so as to the big footpath section of fixation in tank body 1；When big footpath section is screwed in tank, quilt
The filter cake and surplus solution that scraper plate 6 is scraped can be by discharging at bottom opening.
In order to coordinate the rotation of cock 9, the fixed mount 8 to include tapered jaw section and straight pawl section, the straight pawl section in four claw type
It is connected on the anchor ring of retainer ring 7, the tapered jaw section connects cock 9.The present embodiment fixed mount 8 is to connect using four paws structure
Intensity is improved, it would however also be possible to employ Three-claw type etc.；It includes straight pawl section and tapered jaw section, and being disposed to of straight pawl section coordinates cock
9 screw-in certain distances prevent fixed mount 8 from blocking the bottom of screen pipe 3, and be connected ring 7 its length of straight pawl section can set as needed
Put, tapered jaw section is used to connect cock 9.
In the present embodiment, the scraper plate 6 has 4, is connected on the inner ring of retainer ring 7 and uniformly circumferentially arranges, the fixation
Ring 7 has 2 to arrange one on the other and the straight pawl section of 7 Connection Bracket of lower section retainer ring 8.The setting of scraper plate 6 is illustrated in figure 2,
Even and direction is unanimously.Ensure that scraper plate 6 is unlikely to break-in or change in rotation using 2 or multiple retainer rings 7 are setting up and down
Shape.
The screen pipe 3 is closed microporous pipe, and top surface is provided with hole and connects filtrate conduit 4.Screen pipe 3 is to adopt polyester
Microporous pipe made by material etc., especially has filtration to ferrous sulfate, and body closing, top surface perforate is used to connect filtrate
Pipeline 4.
To ensure the sealing at the bottom opening of tank body 1, i.e., it is provided with sealing ring 10 at the described bottom opening screw thread of tank body 1.
Sealing ring 10 is adapted the certain sealing of guarantee with spiral lamination.
In view of scraper plate 6 and the friction damage of screen pipe 3, the scraper plate 6 forms angle with the corresponding outer surface of screen pipe 3,
The angle is 30～60 degree.This angle offset scrapes sharp direction, protects scrape point to a certain extent.
The utility model removes filter cake using scraping mode, rational in infrastructure, is effectively reduced filtration because removing used by filter cake
Time, substantially increase operating efficiency.
