Description

A kind of scraper device and pressing filter with filter cloth cleaning function
Technical field
The utility model relates to filter technical field more particularly to a kind of scraper device with filter cloth cleaning function and Pressing filter.
Background technique
Pressing filter is the mistake being separated by solid-liquid separation for each metalloid or nonmetallic ore pulp and other material slurries such as thin, viscous Filter equipment.Currently, pressing filter will be by filtering, drying, blowback discharging, scraper discharging, discharge, cleaning during shutdown filter when working The courses of work such as cloth.Since during the filtration process, thin, the viscous material of a part can be attached in filter cloth surface or filter opening, anti- It can not be completely fallen off when blowing cake discharge, to block filter opening, the filter efficiency in next cyclic process be caused to reduce.It therefore must Periodic cleaning must be carried out with high pressure water to filter cloth, to guarantee the good air permeability of filter cloth, improve filter efficiency.Original cleaning filter cloth dress It is set to the steel pipe for being provided with multiple spray orifices, is arranged in the filter disc two sides of discharge device for scraper opposite side, is attached to for being cleaned after stopping The regeneration of material on filter disc, filter cloth can only be cleaned after parking, be can not achieve pressing filter and carried out cleaning filter online The drawbacks of cloth blocks after easily leading to filter cloth long time running, and filter effect is deteriorated, and equipment capacity reduces.Realize pressurization Filter carries out cleaning filter cloth online, and after cleaning filter cloth device need to be located at scraper discharging, but filter disc is directly entered after scraper discharging It is for re-filtering in groove body slurry, no space setting cleaning filter cloth device.Therefore, a kind of scraper device for cleaning filter cloth is designed It is imperative.
Utility model content
Purpose of the utility model is to solve disadvantages existing in the prior art, and the one kind proposed has filter cloth clear Wash the scraper device and pressing filter of function.
To achieve the goals above, the utility model adopts the technical scheme that
A kind of scraper device with filter cloth cleaning function, including being separately positioned on the two sides of filter disc and structure pair on groove body Two scraper mechanisms claimed, the scraper mechanism include scraper base, scraper, nozzle and high-pressure hose, and the scraper base is one end Sealing, the other end are equipped with the rhs-structure of water inlet pipe, and described high-pressure hose one end connects water inlet pipe, and the other end connects water injection pipe, The upper end of scraper base is arranged in the scraper, and the lower end of the scraper base is evenly equipped with nozzle along its length, the nozzle Open Side Down, and the scraper base is in tilted layout on groove body, and the blade of the scraper and filter disc setting in a certain angle are described to scrape The point of a knife of knife has at regular intervals with filter disc.
Preferably, the upper end of the scraper base is provided with scraper gusset piece, for coupling scraper, the lower end of the scraper base It is evenly equipped with nozzle bearing, for coupling nozzle.
Preferably, the scraper is fixed by screws on scraper gusset piece.
Preferably, the scraper base is fixed on groove body by scraper base connecting plate.
Preferably, the lower end surface of the scraper base is obliquely installed with groove body top surface in 45 °.
Preferably, the nozzle spray shape is sector.
The utility model also provides a kind of pressing filter, including the above-mentioned scraper device with filter cloth cleaning function.
The utility model has the beneficial effects that
The utility model is provided with nozzle in scraper device, can carry out the regenerability of cleaning filter cloth, filter cloth online Well, high production efficiency, filter cloth service life is long, maintenance cost is low, the labor intensity of worker is low;Scraper base is in tilted layout in groove body On, so that the oblique filter cloth of nozzle, can carry out covering cleaning, and nozzle sprays to obtain the fan-shaped shape of water to filter cloth, there is cleaning model Enclose feature big, that cleaning speed is fast;The blade of scraper and filter disc setting in a certain angle, the point of a knife and filter disc of scraper have certain Spacing is not only able to avoid scraping rotten filter cloth, and scraper can not be caused to remain and block when wiping the filter residue on filter cloth off.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model;
Fig. 2 is sectional view of the Fig. 1 along line A-A.
In figure: 1- groove body, 2- filter disc, 3- high-pressure hose, 4- water injection pipe, 5- scraper base, 6- scraper, 7- nozzle, 8- water inlet Pipe, 9- scraper base connecting plate.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.
As depicted in figs. 1 and 2, a kind of scraper device with filter cloth cleaning function, including be separately positioned on groove body 1 and filter The two sides of disk 2 and two scraper mechanisms of symmetrical configuration, filter cloth is provided on filter disc 2, and two scraper mechanisms are used for filter cloth Filter residue wipe off, specifically, the scraper mechanism includes scraper base 5, scraper 6, nozzle 7 and high-pressure hose 3, the scraper base 5 For an end closure, the other end is equipped with the rhs-structure of water inlet pipe 8, and described 3 one end of high-pressure hose connects water inlet pipe 8, and the other end connects Water injection pipe 4 is connect, the scraper base 5 is in tilted layout on groove body 1 by scraper base connecting plate 9, it is preferred that the scraper base 5 Lower end surface is obliquely installed with 1 top surface of groove body in 45 °, and the upper end of the scraper base 5 is provided with scraper gusset piece, for coupling scraper 6, the scraper 6 is fixed by screws on scraper gusset piece, replacement easy to disassemble, and the blade and filter disc 2 of the scraper 6 are in one The setting of clamp angle, point of a knife and the filter disc 2 of the scraper 6 have at regular intervals, are not only able to avoid scraping rotten filter cloth, and can be Scraper is not caused to remain and block when wiping the filter residue on filter cloth off, the lower end of the scraper base 5 is evenly equipped with spray along its length Mouth 7, Open Side Down for the nozzle 7, and nozzle 7 is fixed on the nozzle bearing of the lower end of scraper base 5, due to inclining for scraper base 5 Tiltedly, so that nozzle 7 is diagonally disposed in 45° angle with filter disc 2, covering cleaning can be carried out to filter cloth, 7 spray shapes of nozzle are Sector, scraper base 5 are in tilted layout on groove body, have the characteristics that clean range is big, cleaning speed is fast.
