Abstract
The utility model relates to a powder separation device for a disintegrating machine, which is characterized in that a grading wheel is arranged in a barrel body (2) of a disintegrating machine. The lower side of the shaft center of the grading wheel is connected with a grading wheel shaft (3), and a plurality of grading wheel vanes (5) which use the grading wheel shaft as a center to radiate in a radial direction are arranged on the grading wheel. A powder outlet barrel body (9) is arranged above the grading wheel, and an airtight gap (1) is arranged between the lower end surface of the powder outlet barrel body (9) and the upper end surface of the grading wheel. The utility model can simultaneously disintegrate and separate powder, and can be used for industries of medicines, chemical engineering, etc.
Description
In the prior art, the powder pulverizer generally is with high pressure draught material to be pulverized, and does not reach material fluidisation in staving of grinding particle size, is subjected to the impact of air-flow repeatedly and reaches the granularity of regulation at last.But owing to being full of in the staving that powder and material are housed high pressure draught is arranged, so the pressure in the staving is very big, generally need drives bucket after pulverizing end and take out a powder, so structure causes the complex procedures that material is pulverized, and can only pulverize long processing time one barrel by one barrel.
The purpose of this utility model is to provide a kind of powder separation device that can make the powder separation that reaches designated size go out the pulverizer of bucket while pulverizing.
The technical solution of the utility model is: grading wheel is arranged in the pulverizer staving, the below, axle center of described grading wheel is connected with the classification wheel shaft, it is the radially grading wheel blade penetrated of the width of cloth of center with the classification wheel shaft that described grading wheel is provided with a plurality of, described grading wheel top is the dust outlet staving, is provided with the hermetic seal gap between the lower surface of dust outlet staving and the grading wheel upper surface.
The utility model compared with prior art has following advantage:
(1). because grading wheel is connected with the classification wheel shaft of below, when grading wheel rotates at a high speed, can make the thin particle of a part enter the grading wheel internal cavity by the gap between the grading wheel blade, be subjected to barrel effect of inner high voltage gas, particle can enter the dust outlet staving again, the grading wheel rotating speed is high more, then isolated finer particles.
(2). the hermetic seal gap between dust outlet staving and the grading wheel blows out owing to high pressure draught portals from air-flow, so between dust outlet staving and grading wheel, can form the hermetic seal gap, can stop not separated powder directly to enter the dust outlet staving in the gap thus, not influence the rotation of grading wheel again.
The utility model will be further described below in conjunction with drawings and Examples:
Accompanying drawing 1 is structure master's cutaway view of the present utility model;
Accompanying drawing 2 is the A-A direction cutaway view (amplifying the back) of accompanying drawing 1; Wherein:
[1]. the hermetic seal gap; [2]. the pulverizer staving; [3]. the classification wheel shaft; [4]. the grading wheel internal cavity; [5]. the grading wheel blade; [6]. air-flow portals; [7]. the pressure air cavity; [8]. the air-flow hand-hole; [9]. the dust outlet staving; [10]. support mast.
Embodiment: referring to accompanying drawing 1 and accompanying drawing 2, grading wheel is arranged in the pulverizer staving [2], can rotate in this staving.The below, axle center of described grading wheel is connected with classification wheel shaft [3], make that grading wheel can high speed rotating, it is the radially grading wheel blade [5] penetrated of the width of cloth of center with the classification wheel shaft that described grading wheel is provided with a plurality of, described grading wheel top is dust outlet staving [9], is provided with hermetic seal gap [1] between the lower surface of dust outlet staving [9] and the grading wheel upper surface.The radial width of described grading wheel blade [5] is 18～22 centimetres, the controllable rotation speed of grading wheel is built in about 3500 rev/mins like this, the radial width of grading wheel blade [5] is more little, then the grading wheel rotating speed of Yao Qiuing is high more, and the powder that only reaches the designated size requirement could enter dust outlet staving [9] by grading wheel.The outside of described dust outlet staving [9] is provided with the pressure air cavity [7] of annulated column shape, this pressure air cavity [7] is provided with forced draft hand-hole [8], this air-flow hand-hole [8] can be imported compressed air, the bottom of this pressure air cavity [7] is annular and is provided with a plurality of air-flows portal [6], these air-flows portal [6] can form the hermetic seal of annular, stop powder to enter dust outlet staving [9], but do not influence the rotation of grading wheel through hermetic seal gap [1].Described each air-flow portal [6] be positioned at the top of grading wheel blade [5], air-flow portal [6] be vertical direction, the end opening of described dust outlet staving [9] is facing to the grading wheel internal cavity [4] of grading wheel hollow.Be convenient to the classified cavity [4] of taking turns of particle and enter dust outlet staving [9].
Claims (5)
1. the powder separation device of a pulverizer, it is characterized in that: grading wheel is arranged in the pulverizer staving [2], the below, axle center of described grading wheel is connected with classification wheel shaft [3], it is the radially grading wheel blade [5] penetrated of the width of cloth of center with the classification wheel shaft that described grading wheel is provided with a plurality of, described grading wheel top is dust outlet staving [9], is provided with hermetic seal gap [1] between the lower surface of dust outlet staving [9] and the grading wheel upper surface.
