Abstract
The utility model discloses an improved structure of a grinding mill, which comprises a barrel-shaped casing. A feed hole is arranged at the side of the casing and a discharge hole is arranged at the top; a screen is arranged on the discharge hole; an air inlet is arranged at the lower part of the casing; a vertical spindle is arranged in the casing; a throwing disc is fixed at the upper end of the vertical spindle; a grinding teeth ring is correspondingly arranged on the inner wall of the casing around the throwing disc; a clamp ring is fixed at the upper part of the throwing disc; and a retaining ring is fixed at the inner side of the discharge hole. The added clamp ring and the retaining ring have the damping function for the air flow with the grinding materials. The large-particle materials fall off to the throwing disc through collision due to sudden turning of the clamp ring and the retaining ring in the rotating and lifting process of the grinded materials when the discharge hole is in the negative pressure, and only the fine materials are screened by the screen along with the air flow, so that the screening efficiency is improved, and the grinding effect is better.
Description
Technical field
The utility model relates to flour mill.
Background technology
Existing flour mill comprises housing, and described housing sidepiece is provided with charging aperture, the top is provided with discharging opening, goes out charging aperture and is provided with screen cloth, and lower housing portion is provided with air inlet, be provided with vertical spindle in the housing, the upper end of vertical spindle is fixed with the material casting dish, and inner walls is provided with roll flute around material casting dish correspondence.The material casting dish sifts out fine particle through the discharging opening screen cloth after material is thrown to roll flute and ground under the effect of blowing.In blowing to the material of outlet, also include the material of larger particles, influenced screening effeciency, the particle that then much should sift out discharging opening falls the material casting dish again.
The utility model content
Technical problem to be solved in the utility model just provides a kind of abrasive dust better effects if, and the flour mill that screening efficiency is high improves structure.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of flour mill improves structure, the housing that comprises tubbiness, described housing sidepiece is provided with charging aperture, the top is provided with discharging opening, discharging opening is provided with screen cloth, lower housing portion is provided with air inlet, be provided with vertical spindle in the housing, the upper end of described vertical spindle is fixed with the material casting dish, described inner walls is provided with the roll flute circle around material casting dish correspondence, and it is characterized in that: described inner walls is fixed with snap ring on material casting dish top, and described discharging opening inboard is fixed with collar.
Preferably, described housing is provided with feed pipe in the charging aperture outside, and described feed pipe is provided with loading hopper, is provided with screw propulsion rod in the described feed pipe.
Preferably, described vertical spindle is located in the cannulated sleeve, and the vertical spindle lower end passes cannulated sleeve and by belt drives, cannulated sleeve is supported by the gripper shoe that is fixed in the housing, is provided with bearing between described vertical spindle and cannulated sleeve.
The snap ring that the utility model is set up, collar play damping action to the air-flow of carrying comminuting matter secretly.Under the effect of discharging opening place negative pressure (extension set is taken out in the discharging opening connection), by in the comminuting matter rotation uphill process through the unexpected break-in of snap ring, collar, material than coarsegrain falls on the material casting dish again through collision, have only thinner material just to sift out by screen cloth with air-flow, thereby having improved screening efficiency, the abrasive dust effect is better.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further described:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, be the embodiment of a kind of flour mill improvement of the utility model structure, comprise the housing 1 of tubbiness, described housing sidepiece is provided with charging aperture 2, the top is provided with discharging opening 3, discharging opening is provided with screen cloth 31, and lower housing portion is provided with air inlet 7, is provided with vertical spindle 4 in the housing, the upper end of described vertical spindle is fixed with material casting dish 5, described inner walls is provided with roll flute circle 6 around material casting dish correspondence, and described inner walls is fixed with snap ring 11 on material casting dish top, and described discharging opening inboard is fixed with collar 12.Described housing is provided with feed pipe 21 in the charging aperture outside, and described feed pipe is provided with loading hopper 22, is provided with screw propulsion rod 23 in the described feed pipe.Described vertical spindle is located in the cannulated sleeve 9, and the vertical spindle lower end passes cannulated sleeve and by belt drives, cannulated sleeve is supported by the gripper shoe 8 that is fixed in the housing, is provided with bearing between described vertical spindle and cannulated sleeve.
