Specific embodiment
With reference to the accompanying drawing, the utility model is further described.
As shown in Figures 1 to 4, a kind of drum-type filter device, including slurry vessel 1 and cartridge filter 3, under the cartridge filter 3
Half portion is immersed in the slurry vessel 1, and the slurry vessel 1 is for placing slurries, and interior setting agitating device is for stirring slurry
Uniformly, the cartridge filter 3 is hollow structure, and internal chamber is filter chamber 31, and hollow rotating cylinder is arranged among the filter chamber 31
32,32 surface of rotating cylinder covers metal mesh 34, and 34 surface of metal mesh covers filter cloth 35, and metal mesh 34 is stainless (steel) wire,
For being supported to filter cloth 35.Slurries are from outside discharge machine, filter cake is then retained by filter cloth inside rotating cylinder 32, to make liquid, consolidate
Mutually separated.
In specific implementation, rotating cylinder 32 is set as rotating clockwise, and in order to slow down filter cloth stopping state, improves it and uses the longevity
Life and filter efficiency, the rinse-system 36 of the 3 inner wall upper left corner of the cartridge filter setting multi-angle, 3 inner wall of cartridge filter are right
Revolving scraper system 37 is arranged in side, and the discharging being made of scraper 38 and bottom plate 39 is arranged below the scraper system 37
Slot, the blowpit is used to collect scraper system 37 and filter cake that scraper 38 is unloaded from filter cloth 35, on 3 inner wall of cartridge filter
The discharge nozzle 33 for filter cake to be discharged is installed close to the blowpit terminal position.
The utility model further includes type washing trough 2 and the high-pressure hydraulic pump 4 that is arranged in the type washing trough 2, described to wash
The outside that sink 2 is generally located on cartridge filter 3 is washed, as shown in Fig. 2, the rinse-system 36 includes by the spray of three groups of different angles
The jet pipe group 363 that pipe is constituted, the jet pipe group 363 are connected by high-pressure water pipe 361 with high-pressure hydraulic pump 4, the jet pipe
Group 363 is fixed on 3 inner wall of cartridge filter by fixed block 362, and the jet pipe group 363 includes the first spray from bottom to top
The tangent line folder of pipe 363a, the second jet pipe 363b, third jet pipe 363c, the first jet pipe 363a and 32 direction of rotation of rotating cylinder
Angle is obtuse angle, and the tangent line angle of the second jet pipe 363b and 32 direction of rotation of rotating cylinder is right angle, the third jet pipe
363c and the tangent line angle of 32 direction of rotation of rotating cylinder are acute angle, are rushed from different perspectives to filter cloth by three groups of jet pipes
It washes, so that flushing is more comprehensive, slows down filter cloth blockage.Liquid is extracted from type washing trough 2 by high-pressure hydraulic pump 4 and is carried out
Then pressurization is rinsed filter cloth, so that discharge pressure is bigger, flushing effect is more preferable.
When drum-type filter device is filtered slurries, the scraper for scraping off filter cake damages filter cloth
It is the key factor for influencing filter cloth service life and effect, so being provided with revolving scrape in 38 front end of the utility model scraper
Material system 37, as shown in Figure 3-4, the scraper system 37 by be fixed on 3 inner wall of cartridge filter pedestal 371, be mounted on
The bearing block 372 at shown 371 both ends of pedestal, is arranged at described turn the shaft 373 being mounted between two bearing blocks 372
The blade 374 of the long chip of multiple groups on 373 surface of axis, the blade 374 are distributed by center annular array of 373 central axes of shaft,
The blade 374 is combined by solid scraper plate and the soft tooth of rubber, and scraper plate is close to the part of shaft 373, and the soft tooth of rubber is
Far from shaft 373 close to the part of filter cloth 35.The top of the scraper 38 is soft brush configuration, is driven when being rotated using shaft 373
The shear force of blade 374 scrapes the filter cake on filter cloth 35, while scraper 38 strikes off remaining filter residue on filter cloth 35.

Cloth 35 causes to damage, and 373 rotation direction of shaft and 32 rotation direction of rotating cylinder are on the contrary, as rotating cylinder 32 is set as turning clockwise
Dynamic, then shaft 373 is set as rotating counterclockwise, and the expulsion efficiency of filter cake, reversely rotated direction can be improved in the opposite shear force of rotation
Being on the one hand to, which prevents shaft 373 from filter cake being brought when rotating, causes shaft 373 to the fine crack between shaft 373 and pedestal 371
It is stuck, on the other hand it is convenient for the filter cake scraped falling into blowpit between scraper 38 and bottom plate 3 along the direction that shaft 373 rotates
It is interior.In implementation process, the soft tooth of the rubber of rotation is loosened and is scraped to the filter cake on filter cloth 35, and soft toothing is not easy to filter
Cloth causes to damage, and the soft tooth of the rubber of blade 374 will alleviate lower section scraper 374 to the dynamics of filter cloth 35 scraped.
It is to be appreciated that rotating cylinder 32 includes dispensing head, the compressed air hose for being divided into fan-shaped lattice differing from each other, center
Road, vacuum pipe etc., and be provided as outside cartridge filter 3 373 power of rotating cylinder 32 and shaft transmission system and pipeline it is mating
The devices such as vacuum pump, above-mentioned apparatus and structure are the conventional arrangement of drum-type filter device, are not indicated in attached drawing.
The above only expresses preferred embodiments of the present invention, and the description thereof is more specific and detailed, but not
Therefore it can be interpreted as that a limitation on the scope of the patent of the present invention.It should be pointed out that for the ordinary skill people of this field
For member, without departing from the concept of the premise utility, several deformations can also be made, improves and substitutes, these all belong to
In the protection scope of the utility model.Therefore, the scope of protection shall be subject to the appended claims for the utility model patent.
