Abstract
The utility model relates to a three-roller grinder, which comprises a grinder body, a feed port, a discharge port and a grinding roller set, wherein a discharge device is installed at the discharge port; the grinding roller set is composed of a first roller, a second roller meshed with the first roller and a third roller meshed with the second roller; the axis of the first roller is in hinged connection with the axis of the second roller through a first connecting rod, and the axis of the second roller is in hinged connection with the axis of the third roller through a second connecting rod; a U-shaped cooling water tube is respectively arranged on the inner walls of the first roller, the second roller and the third roller, and the U-shaped cooling water tube penetrates through the grinder body to be connected with a cooling water tank; and a cooler is installed in the cooling water tank. The three-roller grinder adopts the three rollers with a triangular structure, so that the horizontally applied force is reduced, the structure is firmer, and the service life of the grinder is prolonged. The cooler is combined with the rollers, so that the temperature of the rollers can be effectively reduced and the evaporation of a solvent is reduced during the use.
Description
Technical field
The utility model relates to the technical field of machinery, especially a kind of three-roll grinder.
Background technology
Three-roll grinder can be divided into the experiment three-roll grinder and produce two kinds of three-roll grinders.Three-roll grinder is the most effective grinding of high-viscosity material, dispersing apparatus.Be mainly used in the grinding of the liquid slurries such as various paint, printing ink, pigment, plastics, cosmetics, soap, pottery, rubber and plaster material.The three-roll grinder operation principle: the surface of three rollers by the level mutually friction of extruding and friction speed reaches grinding effect.The roller material of three-roll grinder is that chill alloy cast iron centrifugal casting forms, and case hardness reaches more than HS70 °; The diameter of roller is through high-accuracy grinding, and is accurately fine and smooth, and the fineness of grind of material is reached about 15 μ m, therefore can produce the high-quality product of uniform and smooth.Three-roll grinder is the most effective grinding of high-viscosity material, dispersing apparatus.
Design between three rollers that use at present all is on the same level face, this grinder is when grinding, it is mutual, and to be subjected to the line of force to be in the same level face vertical with each roller gravity, wearing and tearing between the aggravation roller, shorten the service life of grinder, carry out in the process of lapping at roller in addition, roller easily is heated, the performance of solvent when causing easily roller to grind, thus product quality affected.
The utility model content
The technical problems to be solved in the utility model is: in order to overcome the problem of above-mentioned middle existence, provide a kind of three-roll grinder, its project organization is reasonable and grinding effect good, long service life.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of three-roll grinder, comprise the grinding body, be opened in and grind charging aperture and the discharging opening on the body and be installed in the grinding roller group of grinding in the body, described discharging opening place is equipped with drawing mechanism, described grinding roller group is by the first roller, the second roller that is meshed with the first roller and the 3rd roller that is meshed with the second roller form, pass through the head rod chain connection between the axle center of the axle center of the first roller and the second roller, pass through the second connecting rod chain connection between the axle center of the axle center of the second roller and the 3rd roller, described the first roller, be provided with U-shaped cooling water pipe on the second roller and the 3rd roller inwall, U-shaped cooling water pipe passes the grinding body and is connected with cooling water tank, and cooler is installed in the cooling water tank.
In order to improve the coating that separates the variable grain size, described drawing mechanism comprises the main funnel that is connected with discharging opening, and the both sides of main funnel offer respectively the left shunt passage and part circulation road on the right side, and the import of described main funnel is greater than the outlet of main funnel.
The beneficial effects of the utility model are: described a kind of three-roll grinder, and three rollers of employing triangular structure, it reduces horizontal force, makes its structure more firm, increases service life of a machine; Utilize cooler to combine with roller, can in use effectively reduce the temperature of roller, reduce the volatilization of solvent; Adopt the funnel-form drawing mechanism, can conveniently separate the coating of different-grain diameter, improve the quality of products, it is simple in structure and easy to use.
Description of drawings
