Description of drawings
A kind of device structure and process chart that Fig. 1 uses for technology of the present invention.
Fig. 2 has omitted the vertical view of product collecting pit for Fig. 1.
Among the figure, 1-head tank, 2-Wear-resistant sieve guipure, 3-shower, 4-drier, blower fan is swept in 5-blowback, 6-V-type deflector, 7-backwash liquor V-type deflector; 8-screen cloth is scrubbed roller, 9-product collecting pit, 10-crystal to be purified, 11-spray radius.
The specific embodiment
Below in conjunction with accompanying drawing specific embodiment of the present invention is done further to describe in detail.
As depicted in figs. 1 and 2, a kind of continuous belts driven type surface adsorption crystal purifying technique of the present invention is applicable to that plane of crystal contains the purifying of the crystal of water-fast ash content or water-solubility impurity, and its concrete steps are:
1) chooses the Wear-resistant sieve guipure 2 and the cleaning fluid of respective aperture according to the kind of crystal 10 to be purified.Usually, Wear-resistant sieve guipure 2 selects for use aperture and this cleaning size of microcrystal sizable, and cleaning fluid is then selected the pure saturated solution of crystal 10 to be purified for use.For example: when salt was purified, Wear-resistant sieve guipure 2 selection apertures were in 1 ~ 4mm scope, and cleaning fluid adopts saturated NaCl solution; When sucrose was purified, Wear-resistant sieve guipure 2 selection apertures were in 6 ~ 10mm scope, and cleaning fluid adopts saturated sucrose solution; When ammonium sulfate was purified, Wear-resistant sieve guipure 2 selection apertures were in 4 ~ 8mm scope, and cleaning fluid adopts saturated ammonium sulfate solution etc.;
2) deliver to crystal 10 to be purified on the Wear-resistant sieve guipure 2 that recycles continuously from head tank 1; As shown in Figure 2; Under the drive of movable roller, Wear-resistant sieve guipure 2 is delivered to shower 3 belows by the constant speed of 1 ~ 3m/min with crystal 10 to be purified, and shower 3 adopts 2 ~ 4 grades to strengthen hydro-peening effect (present embodiment adopts 4 grades); The flow of every grade of shower 3 is 60 ~ 80L/min; Every grade of shower 3 adopts 3 ~ 5 vaporific nozzles to increase hydro-peening area coverage (present embodiment adopts 3 nozzles), and the flow velocity of each nozzle is 5 ~ 8m/s, with cleaning fluid hydro-peening crystal 10 about 20 ~ 40min to be purified; Simultaneously, the V-type deflector 6 of Wear-resistant sieve guipure 2 belows, shower 3 corresponding position is collected the cleaning fluid behind the hydro-peening, after deposition, filtration, gets into shower 3 again and reuses;
3) crystal behind the hydro-peening continues to carry with Wear-resistant sieve guipure 2, carries out drying to drier 4.Present embodiment adopts the closed drier, is beneficial to the dehydration of crystal, and uses the radiant type mode of heating, avoids impurity to introduce the pollution that causes crystal again, and the dry time is 5 ~ 10min;
4) dried crystal is toppled over (in the present embodiment, the angle of inclination is 75 °) through 2 anti-obliquities of Wear-resistant sieve guipure, and sweeps in blowback under the effect of blower fan 5 and separate with Wear-resistant sieve guipure 2, collects clean crystal with product collecting pit 9.Blower fan 5 power 200kw, rotating speed 450r/s are swept in blowback in the present embodiment;
5) with clean crystal separation after Wear-resistant sieve guipure 2 carry out after cleaning fluid hydro-peening and screen cloth scrub roller 8 and scrub, its mesh is unobstructed, can get into again to recycle.It is 40 ~ 60cm that screen cloth in the present embodiment is scrubbed roller 8 diameters, and backwash shower flow velocity is 5 ~ 8m/s, and the scavenging period of Wear-resistant sieve guipure 2 is 15 ~ 25min; Simultaneously, the backwash liquor V-type deflector 7 of Wear-resistant sieve guipure 2 belows, backwash shower corresponding position reclaims the cleaning fluid that said Wear-resistant sieve guipure 2 is carried out hydro-peening, after deposition, filtration, also reuses.So circulation realizes continuous purification production.
Core of the present invention has been to adopt the purification mode of " hydro-peening-drying-separate with the screen cloth band ", has realized the minimizing of the energy and resource consumption, and the production capacity that crystal is purified is high.So its protection domain is not limited to the foregoing description.Obviously, those skilled in the art can carry out various changes and distortion and do not depart from the scope of the present invention and spirit the present invention.For example: it is said that the concrete equipment of purification is not limited to embodiment, adopts the mechanism and the equipment that satisfy the corresponding steps requirement all to can be used for technology of the present invention; The parameter of each step also can rationally be confirmed according to the kind of crystal 10 to be purified etc.If these changes and distortion belong in the scope of claim of the present invention and equivalent technologies thereof, then the present invention also is intended to comprise these changes and is out of shape interior.
