Abstract
The utility model discloses a sand mill which comprises an inlet, a main body and an outlet. The inlet is connected with a hopper, and the outlet is connected with a material barrel. An intermediate speed rotating head and a first filtering screen are arranged between the hopper and the inlet sequentially, a second filtering screen is arranged between the outlet and the material barrel, and the hole diameter of the second filtering screen is not lager than 0.1mm. The sand mill can reduce agglomeration degree of materials entering the sand mill and reduce loss of grinding balls, the second filtering screen with the small hole diameter can not fail to intercept the grinding balls, and blocking caused by the fact that the grinding balls are stuck can not happen due to precrushing and filtering.
Description
Technical field
The utility model relates to floor coatings process equipment field, particularly relates to a kind of sand mill that prevents that abrasive media runs off.
Background technology
Sand mill is used for the wet lapping of chemistry painting industry, mainly is made up of body, mill tube, disperser, bottom valve, motor and feeding engine, and the speed of charging is controlled by feed pump, needs through screen pack filtering particle during discharging.Abrasive media generally adopts bead, zirconium silicate pearl, zirconium oxide bead or other.According to difference, can add and subtract abrasive media adjustment in right amount to the coating fineness requirement.The abrasive media diameter is more little, and the coating that makes is finer and smoother.But be to use minimum abrasive media; Run off to prevent abrasive media in discharging screen pack aperture corresponding littler (being generally the 1/2-1/3 of abrasive media diameter); But, very easily stop up the discharging screen pack because the effect of Fan Dewaerli is ground the fine paint powders of disperseing and is prone to produce agglomeration again; Influence discharging speed, production efficiency descends.
The utility model content
The technical problem that the utility model will solve provides a kind of sand mill, can either prevent effectively that abrasive media runs off, and does not influence discharging speed again.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of sand mill, comprise inlet, main body and outlet, and inlet connects hopper, outlet attachment charging basket.Be provided with the middling speed swivel head and first filter screen successively between hopper and the inlet, establish second filter screen between outlet and the material barrel, the second filter screen aperture is not more than 0.1mm.
Preferably, sand mill also comprises the side room that is connected with main body, is provided with the valve of automatic control between side room and the main body.
Preferably, sand mill also comprises the automatic control unit in order to control rotating speed, milling time and said valve folding.
The sand mill of the utility model reduces the reunion degree of the material that gets into sand mill through precomminution and filtration, has reduced the loss of mill ball, makes second filter screen of small-bore neither can leak the obstruction mill ball, also can not stop up because of blocking mill ball.
Description of drawings
Fig. 1 is the structural representation that the utlity model has sand mill one preferred embodiment of filtering function.
The specific embodiment
Below in conjunction with accompanying drawing the preferred embodiment of the utility model is set forth in detail, thereby the protection domain of the utility model is made more explicit defining so that advantage of the utility model and characteristic can be easier to it will be appreciated by those skilled in the art that.
See also Fig. 1, the sand mill 1 of the utility model, inlet connects hopper 2, outlet attachment charging basket 3.Between hopper and sand mill 1 inlet, be provided with the middling speed swivel head 5 and first filter screen 4 successively, the lump material that condenses is pulverized in advance and is got into sand mill 1 through first filter screen 4.
Mill ball in the sand mill 1 is selected wear-resisting zirconia media, and diameter is 0.3-0.4mm.Establish second filter screen, 6, the second filter screens, 6 apertures between sand mill 1 outlet and the material barrel 3 and be not more than 0.1mm, prevent that mill ball is stuck on second filter screen 6.
The sand mill 1 of the utility model, its main body connects side room 7, is used to place interface modifier.The effect of interface modifier is the coacervation again that reduces powder.Be provided with the valve 8 of automatic control between the main body of side room 7 and sand mill 1.
The sand mill 1 of the utility model also comprises automatic control unit.This unit is in order to rotating speed, the milling time of setting sand mill, and the folding of by-pass valve control 7, can be according to each parameter of property settings of material.After material grinds the time of setting through sand mill 1, reach suitable granularity, this moment, by-pass valve control 7 was opened, and injected quantitative interface modifier, and valve-off 7 then, and continuation mixing material can effectively reduce the particle diameter of powder.After accomplishing sand milling, diameter of particle can be successfully through second filter screen, 6 inflow charging baskets 3 much smaller than 0.1mm, and mill ball then is arrested in the sand mill 1 by second filter screen 6.
The sand mill of the utility model reduces the reunion degree of the material that gets into sand mill through precomminution and filtration, has reduced the loss of mill ball; Through adding the device of interface modifier, the powder after preventing to pulverize is conglomerate once more, makes the filter screen of small-bore neither can leak the obstruction mill ball, also can not stop up because of blocking mill ball again.
The above is merely the embodiment of the utility model; Be not thus the restriction the utility model claim; Every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the utility model.
Claims (3)
1. sand mill; Comprise inlet, main body and outlet; It is characterized in that: inlet connects hopper, and outlet attachment charging basket is provided with the middling speed swivel head and first filter screen between said hopper and the inlet successively; Establish second filter screen between said outlet and the material barrel, the said second filter screen aperture is not more than 0.1mm.
2. sand mill according to claim 1 is characterized in that: also comprise the side room that is connected with main body, be provided with the valve of automatic control between said side room and the main body.
