Abstract
The utility model relates to a scrapper used in a belt filter press. Due to formation of a U-shaped groove in a scrapper body and arced design of the working plane of the scrapper, abrasion and damage to a piece of filtering cloth caused by an ordinary scrapper can be alleviated, the cleaning of adhered substances on the surface of the filtering cloth when the substance is scrapped is effectively improved, and meanwhile, due to design of the arced top, the consumption of the scrapper is reduced, so that reliable and effective working of equipment is achieved.
Description
Technical field
The utility model relates to a kind of scraper, and particularly a kind of scraper using on belt filter press, belongs to environmental protection production technical field.
Background technology
Belt filter press, as the main machine of processing viscosity bulky grain dirt, has a wide range of applications at chemical industry and the metallurgical numerous areas that waits.Scraper is as the higher parts of frequency of utilization on belt filter press, the zone face of its blade face and strainer cooperatively interacts, being bonded in material scraper on strainer from conveyer belt surface, to guarantee that strainer zone face can not cause because of piling up too many granule materials the reduction of transfer efficiency.And the scraper of the belt filter press using in the market generally adopts the materials such as bakelite plate or iron plate to be made, and scraper is fixed on doctor blade holder with bolt, but such arranging can produce following point: due to scraper, adopt the hard wear-resistant materials such as plank to make, its toughness is not good, scraping off in material process, if encounter sharp-pointed, hard object, easily fracture; Scraper originally, in the process contacting with strainer, because material is harder, can cause Stress damage to the filter cloth on strainer, greatly shortens the service life of filter cloth, has improved use cost; Be arranged on scraper on doctor blade holder because angle can not be adjusted, once occur, after blade wears or breach, cannot normally using, can only change.
Utility model content
The technical problems to be solved in the utility model is: a kind of capable of regulating depth stroke is provided and wear and tear little, filter cloth is damaged to little scraper.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of scraper for belt filter press, by scraper body and scraper working face two parts, formed, described scraper body lower end is provided with U-lag, U-lag is equidistantly arranged on scraper body, the side lines of scraper working face from afterbody to top are the arc caving inward, and the top of scraper working face is set to circular arc.Adopt this kind of design, can guarantee that scraper is when work, the contact damage of scraper to filter cloth, the service life of improving filter cloth can be effectively protected in the circular arc design at its top; And the design of the arc of side lines can guarantee that scraper is striking off after material, material can be discharged fast along arc port.Compare with common scraper, there is working face and be subject to that pressure resistance is little, little to the damage of filter cloth, material is discharged advantage rapidly.
The depth degree of depth of described U-lag is 1/2 of scraper body.Adopt this kind of design, can be according to the size of filter press roller, the stroke of flexible modulation scraper, effectively avoids deeply causing not the sordid situation of scraper because of scraper depth; After scraper top may wear to a certain degree, can unclamp the set bolt being fixed in U-lag simultaneously, after scraper is moved in depth, be fixed again, to form, the follow-up wearing and tearing of scraper working face be supplemented.
The material of described scraper is made by ultra high molecular polyethylene.Adopt this kind of design, can reduce the consumption of scraper, reduce production costs.
The utility model is by arranging the arc design of U-lag and scraper working face to scraper, can greatly reduce wearing and tearing and the damage of common scraper to filter cloth, and clean to filter cloth surface adhesive while effectively improving scraper, simultaneously the top design of circular arc can reduce the consumption of scraper, thus realize equipment reliably, effectively work.

Fig. 2 is front view of the present utility model;
Fig. 3 is scraper scheme of installation of the present utility model;
Fig. 4 is work schematic diagram of the present utility model.
Specific embodiment
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, a kind of scraper for belt filter press, by scraper body 2 and scraper working face 1 two parts, formed, described scraper body 2 lower ends are provided with U-lag 3, U-lag 3 is equidistantly arranged on scraper body 2, the side lines of scraper working face 1 from afterbody to top are the arc caving inward, and the top of scraper working face is set to circular arc 4.
The depth degree of depth of described U-lag 3 is 1/2 of scraper body.
The material of described scraper is made by ultra high molecular polyethylene.
Before equipment operation, first scraper is arranged on doctor blade holder, screw is through U-lag and by pressing plate 5 fixed doctor positions, and the side lines arc of scraper working face is outwards placed.During equipment operation, the filter cloth 6 of the top of scraper working face and belt filter press is contacted, along with the rotation of machine, the material being bonded on filter cloth 6 splits away off from filter cloth 6 by scraper, and discharges fast.And U-lag can play when scraper top rapid wear, when effect is struck off in impact, can unclamp screw, scraper entirety is moved inward, proceed operation.
Claims (3)
1. the scraper for belt filter press, by scraper body and scraper working face two parts, formed, it is characterized in that: described scraper body lower end is provided with U-lag, U-lag is equidistantly arranged on scraper body, the side lines of scraper working face from afterbody to top are the arc caving inward, and the top of scraper working face is set to circular arc.
2. scraper according to claim 1, is characterized in that: the depth degree of depth of described U-lag is 1/2 of scraper body.
