Description
Technical field
The utility model relates to a kind of sand mill, belongs to such as external coating material production equipment technology such as paint, coating.
Background technology
The alleged sand mill of the utility model also is referred to as ball mill, is that a kind of be used for to surperficial coating material stirred a kind of process equipment of mill such as paint, coating (metope) etc.
Described external coating material is a kind of solid, liquid phase mixture, stir mill repeatedly through sand mill, its solid-phase material is fully disperseed and be evenly distributed in its liquid phase material, thereby improve the uniformity coefficient of described coating material coating and be coated with adhesion strength, and be difficult for producing be full of cracks and the coating quality problem such as peel off on other object (as furniture, machinery part and body of wall in addition) surface.Thereby described sand mill is a kind of requisite visual plant of external coating material preparation.
Because described external coating material is in sand grinding process, can produce certain heat, and the temperature of described external coating material is raise, this not only can cause the volatilization of the liquid phase organic substance in the described external coating material and reduce its content, directly influenced the technical performance of material to be machined, and the solid-phase material cohesion in the material to be machined is lumpd (subparticle), this has equally also influenced the technical performance of described external coating material.For this reason, existing sand mill has been taked the means of cooling to its material to be machined, makes the temperature of material to be machined in sand grinding process, remains in the normal process scope (for example 30～50 ℃).
Yet existing sand mill is Chinese patent publication number CN1754627A for example, and the means of being taked of cooling are to lay the technical measures of cooling-water duct on central shaft.Undoubtedly, this version, complex structure first, central shaft processing technology difficulty is bigger, and cooling water medium import and export place is essential to adopt swivel joint (pipe fitting), and this swivel joint extremely is easy to generate the cooling medium seepage; Second be the mode of center, sand milling chamber cooling owing to what it adopted, thereby it is to the cooling effect of material to be machined, inevitable poor, still do not reach desirable requirement.For this reason, provide a kind of structure simpler relatively, cooling effect is sand mill relatively better, just becomes insider's expectation.
Summary of the invention
The utility model aims to provide a kind of rational in infrastructure, convenient processing and manufacture, and the sand mill of good cooling results to overcome the deficiency of prior art, satisfies the needs of producing the high-quality surface coating material in the industry.
The utility model realizes that the technical though of its purpose is, material to be machined in the sand milling chamber is drawn, and import in the material cooling device, after the heat exchange that is present in the heat exchanger in the described cooling device, the material to be machined that has cooled is imported in the sand milling chamber, constitute the circulation cooling outside the described material to be machined sand milling chamber like this, thereby realize the purpose of this utility model.
Based on above-mentioned technical though, the utility model realizes that the technical scheme of its purpose is:
A kind of sand mill comprises the sand milling device, and its innovative point is, also comprises sand milling material cooling device; Described material cooling device comprises the material cooler bin and is located at the interior heat exchanger of material cooler bin; The cooling medium import and export of heat exchanger respectively pipeline be connected with inlet tube and outlet, and inlet tube and outlet are drawn respectively outside the material cooler bin; Between material cooler bin and sand milling device, pipeline is connected with feed pipe and discharge nozzle respectively, and constitutes material cooler bin inner chamber and sand milling device inner chamber closed loop material channel by feed pipe and discharge nozzle; On the pipeline of feed pipe or discharge nozzle, be provided with material-handling pump.
Can understand by above given technical scheme, the utility model is owing to take the technical scheme of sand milling device extracorporal circulatory system cooling material to be machined, thereby the cooling effect of its material to be machined is significantly improved, especially material to be machined repeatedly into and out of circulation, can effectively improve the sand milling effect of sand milling device, solid-phase material in the material to be machined is evenly dispersed in the liquid phase material more, has further improved the quality of described external coating material; And described cooling device is simple in structure, and processing and manufacturing is easy, there is no fear of producing the cooling medium seepage, and maintaining is also very convenient, thereby has realized the purpose of this utility model.
In technique scheme, the utility model advocates that described material-handling pump is a membrane pump.But be not limited to this.For example adopt slush pump or gear pump etc., also all be fine.
In technique scheme, the utility model advocates that also the cooling medium of described heat exchanger is the water at low temperature of temperature in 1～25 ℃ of scope.The temperature of cooling medium water described here is preferred according to the technical the subject of knowledge and the object of knowledge of described external coating material.By the heat exchange of heat exchanger, the sand milling temperature of material to be machined is remained in 30～50 ℃ of scopes of technological requirement.Here should be noted that under the lower condition of room temperature, particularly in the winter of the northern area of China, the temperature of cooling medium water should appropriateness be heightened.At extremely frigid zones, even cooling medium water can be used instead and be heat medium water, to keep the normal process temperature of sand mill.Thus, described material cooling device also can be referred to as the temperature of charge adjusting device.
In last technical scheme, the utility model advocates that also described heat exchanger is a serpentine heat exchanger, or shell-and-tube exchanger or heat-exchangers of the plate type.But be not limited to this, for example adopt heat exchanger of steam heat warmer structure form or the like, all be fine.Because described serpentine heat exchanger relatively simple for structure, process also easily, be very suitable with it as heat exchanger of the present utility model, thereby the utility model is actively recommended.
The utility model advocates that also the radiating tube of described serpentine heat exchanger is bellows or semicircle pipe.Its purpose is effectively to improve the heat exchange area of described heat exchanger, with the effect that cools of further raising material to be machined.
In technique scheme, the utility model also advocates, described sand milling device is two rollers or multiple roll to rolling formula sand milling device, or radially have the central shaft that grinds bar and sand milling device case inwall set radially grind the mill formula of the stirring sand milling device that pole pair stirs.Certainly, be not limited to this,, all be fine as long as other has the sand milling device in sand milling chamber.
After technique scheme was implemented, what the utility model had was rational in infrastructure, and manufacturing processing is easy, and material to be machined cools effective, and characteristics such as material to be machined quality of finished product good are conspicuous.
