The pulverizing strength of the pulverizing blades can be increased by the angle between the pulverizing blades of the high-speed pulverizer and the horizontal level, and meanwhile the material upward throwing strength is also increased; the screen installed on the bottom of the pulverizing cavity can discharge materials reaching the pulverizing requirement after collection by the material aggregating bin, thereby preventing material pulverizing nonuniformity in the pulverizing process.
Description
Technical field
The utility model relates to the device in crushing technology field, is specifically related to a kind of use for laboratory high speed disintegrator.
Background technology
Materials crusher is raw material processing equipment, and its effect is that material is fiercely hit and forms powder article through the hammer leaf of High Rotation Speed.In the crushing chamber of the conventional materials crusher in existing laboratory, be provided with the hammer leaf being arranged on main shaft, main shaft through High Rotation Speed drives hammer leaf High Rotation Speed, processing materials is carried out to fierce strike and form powder, its charging aperture and discharging opening are all set to one, pulverizing meets the requirements of and does not meet the requirements of and is all positioned at cavity, and experimenter can not grasp exactly material by naked eyes and whether reaches requirement completely in crushing process, in the time that powder is detected and affect the judgement of product quality.In addition, existing use for laboratory high speed disintegrator complex structure, has dismounting trouble, the shortcomings such as inconvenient maintenance.
Utility model content
For above-mentioned deficiency of the prior art, the utility model provide a kind of simple in structure, design ingenious, pulverize great efforts, and in crushing process, can will reach pulverize the use for laboratory high speed disintegrator that the material that requires is discharged automatically.
In order to reach foregoing invention object, the technical solution adopted in the utility model is: a kind of use for laboratory high speed disintegrator is provided, it comprises base and crushing chamber, the lower surface middle part of described crushing chamber is fixed with a collecting bin, described crushing chamber is installed in the draw-in groove on base by collecting bin, and the crushing shaft of described crushing chamber is flexibly connected with the motor output shaft in base; On described crushing shaft, be fixed with two pairs of crushing vanes by nut, axisymmetricly, and angle between the every pair of crushing vane and horizontal plane is 12 °-33 ° to every pair of crushing vane;
The inner surface of described crushing chamber is provided with some pulverizing ribs, and the rotation direction of described pulverizing rib is contrary with the direction of rotation of crushing shaft, and the middle part, bottom surface of crushing chamber is provided with a screen cloth; A discharging opening being communicated with collecting bin is installed on described base.
In implementation process, the lid that a diameter is more than or equal to crushing chamber external diameter is installed on preferred described crushing chamber.
In implementation process, the height of preferred described lid is less than or equal to the height of crushing chamber, and on lid, leader is also installed.
In implementation process, some suckers are installed on the bottom surface of preferred described base.
Compared with high speed disintegrator of the prior art, the beneficial effects of the utility model are:
The angle arranging between the crushing vane of this high speed disintegrator and horizontal plane, can increase the pulverizing dynamics of crushing vane, and has also increased the dynamics that material is upwards dished out simultaneously; The screen cloth that install the bottom of crushing chamber, can meet the requirements of pulverizing material and discharge after collecting bin is collected, thereby has avoided in crushing process the pulverizing of material inhomogeneous;
The pulverizing rib rotation direction of crushing chamber inwall is contrary with crushing shaft direction of rotation, can increase like this shock dynamics of powder and crushing chamber inwall and accelerate the pulverizing of material, has accelerated the grinding time of material; Material is installed on base by the collecting bin of crushing chamber below, facilitates the dismounting of crushing chamber, has facilitated when collecting bin is cleared up and has been convenient to keep in repair.

Detailed description of the invention
As shown in Figure 3, this use for laboratory high speed disintegrator comprises base 8 and crushing chamber 3, is provided with a power line 9 being connected with extraneous power supply on described base 8; The lower surface middle part of described crushing chamber 3 is fixed with a collecting bin 6, and described crushing chamber 3 is installed in the draw-in groove on base 8 by collecting bin 6, and the crushing shaft 5 of described crushing chamber 3 is flexibly connected with the motor output shaft in base 8; On described crushing shaft 5, be fixed with two pairs of crushing vanes 4 by nut, every pair of crushing vane 4 axisymmetricly, through experimental results demonstrate, angle between the every pair of crushing vane 4 and horizontal plane is between 12 °-33 ° time, the pulverizing dynamics maximum of crushing vane 4, also increased the dynamics that material is upwards dished out, while producing crushing vane preferably 23 ° simultaneously.
As shown in Figures 2 and 3, the inner surface of crushing chamber 3 is provided with some pulverizing ribs 2, and the rotation direction of described pulverizing rib 2 is contrary with the direction of rotation of crushing shaft 5, and the middle part, bottom surface of crushing chamber 3 is provided with a screen cloth 11; A discharging opening 7 being communicated with collecting bin 6 is installed on base 8.
After screen cloth 11 arranges, after crushing vane 4 is pulverized, pulverizing dynamics meets the requirements of material and can after collecting bin 6 is collected, discharge, thereby has avoided in crushing process the pulverizing of material inhomogeneous.
As shown in Figure 1, in implementation process, on preferred described crushing chamber 3, the lid 1 that a diameter is more than or equal to crushing chamber 3 external diameters is installed, the height of described lid 1 is less than or equal to the height of crushing chamber 3, and on lid 1, leader is also installed; After arranging like this, can avoid the materials from spattering of kicking up through crushing vane 4 to pollute laboratory environment to laboratory.
Motor in base 8, in High Rotation Speed process, can drive base 8 to vibrate, and in order to increase the stability of base 8, in implementation process, some suckers 10 is preferably installed on the bottom surface of base 8.
