Abstract
The utility model relates to a new improved sand mill, which is mainly used for architectural coating and analogous slurry to be milled and dispersed. The utility model changes the feeding and discharging ways of the present sand mill, cancels the original feeding system of the gear pump, and the feeding and discharging both adopt free fall in order to feed and discharge freely. The feeding way changes from original feeding from bottom to feeding from the top of a cylinder, and the slurry which need mill flows into the cylinder utilizing free fall; the discharging way depends on free fall to expel stuff via small round holes in the chassis of the cylinder, and discharging amount is controlled by the valve in the bottom of the cylinder.
Description
The utility model relates to a kind of improved new sand Mill, is mainly used in the grinding and the dispersion of slurry, particularly is applied to the grinding and the dispersion of building coating and similar material.
At present, both at home and abroad the sand mill that generally uses generally all is made up of feed system and grinding system, and feed system is made up of gear pump and the pipeline that matches and valve; Grinding system is made up of cylindrical shell, bead and dispersion impeller etc.During sand mill work, by gear pump the slurry that needs grind is sent into from the cylindrical shell bottom, dispersion impeller is under the drive of motor, rotation at a high speed in cylindrical shell, drive bead and in cylindrical shell, do irregular movement,, thereby reach the purpose of ground slurry by the frequent collision mutually of bead.Ground slurry is discharged how many how much controlling by the gear pump feeding of discharge from the top of cylindrical shell.By using, mainly there is the shortcoming of two aspects in this sand mill, and the one, the gear pump of feed system breaks down easily, influences the operate as normal of sand mill thus; The 2nd, because the feed system complexity causes the cost of sand mill too high.
The purpose of this utility model is to produce a kind of novel sand mill, and by to grinding system, the particularly improvement of feed system is solved the ubiquitous shortcoming of sand mill of above-mentioned present use.
This sand mill is simple in structure, hazard rate reduces significantly, the product cost reduces significantly, solved owing to now use the sand mill cost too high, cause the unable purchase of many coating material production producers, middle-size and small-size coating material production factory does not use sand mill, causes the low-quality problem of coating products, and economic benefit is apparent in view.
New sand Mill described in the utility model, changed existing charging and marker method with sand mill, cancelled original gear pump feed system, charging and discharge all adopt free drop mode, realize free feed and discharge, feeding manner is changed into by the charging of cylindrical shell top by original bottom feed, utilizes free drop to flow into cylindrical shell, marker method also is to rely on free drop to discharge by the circular hole on the cylindrical shell chassis, how many valve controls bottom cylindrical shell of discharge.Be uniform-distribution with many small sircle holes on the chassis of cylindrical shell, the size of circular hole matches with the size of abrading-ball in the cylindrical shell, passes through to get final product in circular hole not make abrading-ball.Abrading-ball can be glass marble, steel ball or Ceramic Balls etc.
As shown in drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is an A-A profile of the present utility model.
Embodiment below in conjunction with accompanying drawing provides is further described sand mill of the present utility model, and this sand mill comprises cylindrical shell 1, dispersion impeller 2, abrading-ball 3, conical hopper 4, pipeline 5 and valve 6.Cylindrical shell 1 is connected with conical hopper 4, be uniform-distribution with many small sircle holes on the chassis of cylindrical shell 1, the diameter of small sircle hole gets final product less than the diameter of abrading-ball 3 in the cylindrical shell 1, so that abrading-ball 3 is passed through from circular hole, the diameter of small sircle hole can be between 0.05mm～10mm on abrading-ball 3 and cylindrical shell 1 chassis, and the density of small sircle hole can be at 1/cm on cylindrical shell 1 chassis
2～300/cm
2Between, abrading-ball 3 can be glass marble, steel ball or Ceramic Balls etc., dispersion impeller 2 is under motor drives, rotation at a high speed in cylindrical shell 1, drive abrading-ball 3 and in cylindrical shell 1, do irregular movement, the slurry that needs to grind flows freely into by the top of free drop from cylindrical shell 1, by the frequent collision mutually of abrading-ball 3, reaches the purpose of grinding.Ground slurry freely is discharged by the small sircle hole on cylindrical shell 1 chassis, how much being controlled by the valve 6 that is installed in conical hopper 4 bottoms of discharge.
Claims (5)
1, a kind of new sand Mill that is used for building coating and grinding of similar slurry and dispersion, comprise cylindrical shell 1, dispersion impeller 2 and abrading-ball 3, it is characterized in that it has cancelled original gear pump feed system, and charging and marker method have been changed, charging and discharge all adopt free drop, realize free feed and discharge, and charging is on the top of cylindrical shell, discharge is discharged by the small sircle hole on cylindrical shell 1 chassis, and what of discharge are controlled by the valve 6 of cylindrical shell 1 bottom.
2, sand mill according to claim 1 is characterized in that being uniform-distribution with many small sircle holes on the chassis of sand mill cylindrical shell 1.
3, according to claim 1,2 described sand mills, it is characterized in that the diameter of the diameter of small sircle hole on cylindrical shell 1 chassis less than abrading-ball 3 in the cylindrical shell 1, according to the diameter of abrading-ball 3, the small sircle hole diameter is between 0.05 millimeter～10 millimeters.
4,, it is characterized in that small sircle hole density on cylindrical shell 1 chassis is at 1/cm according to claim 1,2 described sand mills
2～300/cm
2Between.
5, sand mill according to claim 1 is characterized in that abrading-ball 3 can be glass marble, steel ball or Ceramic Balls etc.
