The impact pulverizer has the advantages of reasonable structure, proper layout, good tightness, high work efficiency, little power consumption and good quality of machining product without pollution.
Description
The ultrafine crusher of industries such as the utility model relates to and a kind ofly is used to build, metallurgy, chemical industry.
At present, traditional ball mill is to be medium with the steel ball, utilizes collision between steel ball and liner plate, steel ball and the steel ball pulverized material of crushing.The crushing machine of its material can be less than 1/10th, and idle power consumption is very big, and loss of material is also big, and the wearing and tearing of steel ball and liner plate are also more serious simultaneously.And the steel fine powder that worn steel ball gets off can mix in the material, makes the material finished product contain impurity, and quality descends.Dislike the iron material can not adopt this ball mill to pulverize.Traditional ball mill also exists serious problems such as noise is big, dust is many, pollution is heavy, and the infringement workman is healthy.
The purpose of this utility model is to avoid above-mentioned weak point of the prior art, and provide a kind of steel ball medium that do not need, and rational in infrastructure, layout is proper, good airproof performance, work efficiency height, energy consumption is low, pollution-free, powder quality is excellent, install, maintenance, maintenance is the high-speed impact type flour mill very easily.
The purpose of this utility model is to reach by following measure: this impacting type flour mill is to be made of main motor, belt gear, base, bump chamber, suction powder chamber, row's powder chamber, main shaft, upper bearing (metal), lower bearing, feed hopper, meal outlet, air inlet duct and auxiliary-motor.The bump chamber that wherein is positioned at above the base is cylindrical by appearance, and inner chamber is conical down bump chamber body and all is conical with outer surface, inner chamber and goes up the body butt joint of bump chamber and form.And on the circumference that clashes into the chamber intracoelomic cavity down, inlaying the 4-8 piece and making, and having the impingement plate of double wedge by high-abrasive material.Be provided with the collision ring of a circular cone tubular above the impingement plate at these, on the collision ring, also be provided with the dish collision dish that has many apertures on hollow and the peripheral surface simultaneously.Blade-carrying dynamically throw dish below the upper end of main shaft is fixed with it, and allow it be positioned at bump chamber body down.Also on the bump chamber, be provided with in addition and inhale the powder chamber.The row's of being provided with powder chamber again on inhale the powder chamber.Drive the suction impeller of its blade and vertical axis oblique inhaling indoor being equipped with of powder by auxiliary-motor.Drive the air draft impeller of its blade and vertical axis line parallel indoor being equipped with also of row powder by auxiliary-motor.
Can be on the dynamically throw dish in the technical measures of the present utility model, it is at right angles trapezoidal to be fixed with 4-8 its longitudinal section equably along periphery, the acceleration collision block of being made by antifriction alloy.
Can and be provided with one respectively in the body wall of following bump chamber body in the body wall of last bump chamber body in the technical measures of the present utility model and enclose the belt cooling chamber of hollow.
Can below the dynamically throw dish, locate in the technical measures of the present utility model, be provided with the clout porus excretorius in the bottom body wall that clashes into the chamber body down.
Accompanying drawing is a structure chart of the present utility model.
The utility model is described in further detail below in conjunction with embodiment: this flour mill is by main motor (2), belt gear (7), base (12), bump chamber (3), inhales powder chamber (21), row powder chamber (23), main shaft (8), upper bearing (metal) (11), lower bearing (10), feed hopper (1), powder outlet (24), air inlet duct (13) and auxiliary-motor (26) formation as shown in the figure.It is cylindrical by outer surface at first clashing into chamber (3), and inner chamber is the conical chamber body (15) of bump down, all is the butt joint of conical upward bump chamber body (19) with outer surface, inner chamber and forms.Simultaneously on the circumference that clashes into chamber body (15) inner chamber down, inlaying 6 and making, having the impingement plate (16) of double wedge by antifriction alloy.And on these impingement plates (16), also be provided with the collision ring (17) of a circular cone tubular, on collision ring (17), be provided with again a hollow, on the peripheral surface with the dish collision dish (18) of many apertures.Secondly be fixed with small belt pulley (9) in the lower end of main shaft (8), and allow it be positioned at base (12).Be fixed with its periphery that 6 longitudinal sections are housed equably is at right angles trapezoidal in the upper end of main shaft (8), the dynamically throw dish (5) of the acceleration collision block of making by antifriction alloy (4), simultaneously below this dynamically throw dish (5), air draught blade (6) is housed also, and allows it be positioned at bump chamber body (15) down.It three is to be provided with to inhale powder chamber (21) on bump chamber (3).Inhale to be equipped with in the powder chamber (21) and drive the suction impeller (22) of its blade and vertical axis oblique by auxiliary-motor (26).Simultaneously on inhale powder chamber (21) row's of being provided with powder chamber (23) again.In row powder chamber (23), be equipped with also by auxiliary-motor (26) and drive the air draft impeller (25) of its blade and vertical axis line parallel.It four is in the body wall of in the body wall of last bump chamber body (19) and down bump chamber body (15) the belt cooling chamber (20) of a circle to be set respectively.At the place, below of dynamically throw dish (5), be provided with clout porus excretorius (14) at last in the bottom body wall that clashes into chamber body (15) down.
During this flour mill work, mineral aggregate falls on the median surface of dynamically throw dish more equably through the blanking port of feed hopper.Because the high speed rotating of dynamically throw dish is just got rid of the mineral aggregate on the card post on the indoor impingement plate of bump, collision ring, collision dish, makes it to pulverize.Aniseed after the pulverizing under the gravity effect, falls back to again on the dynamically throw dish on the one hand, continues to be got rid of to be up to impingement plate, collision ring, collision dish or other material to collide, and makes it to pulverize again.The elevating screw wind that produces of suction impeller on the other hand, the material of again minority being fallen below the dynamically throw dish sucts, and makes it to continue collision.So material is indoor at bump, constantly pulverized, again constantly indoor the rolling of bump by collision.Only reach the fine silt of release mesh, it is indoor to be inhaled powder by the suction impeller suction, again the row's of entering powder chamber.And then under the effect of air draft impeller, the fine silt that the row's of entering powder is indoor ejects from meal outlet.Do not meet the requirements of material then at the indoor continuation of bump bump, to till qualified.
The utility model has following advantage compared to existing technology: this flour mill is situated between without steel ball Matter, and adopt wind-force and collision to reach the purpose of pulverizing and grinding. Its good airproof performance does not have dirty Dye, be conducive to the healthy of workman, its work efficiency height, energy consumption are low, the product quality that processes Excellent. And this machine is rational in infrastructure, and layout is proper, and operation not only simply but also safety, was installed and maintenance All very convenient. It is a kind of desirable renewal product.
