Description

Silicon micropowder grinder

Technical Field

The utility model relates to the technical field of silicon micropowder, in particular to a silicon micropowder grinder.

Background

The silicon micropowder is micropowder processed from natural quartz or fused quartz (amorphous silicon dioxide obtained by high-temperature fusion and cooling of natural quartz) by multiple processes such as crushing, ball milling (or vibration and jet milling), flotation, acid washing purification, high-purity water treatment and the like; in the silicon micropowder processing process, the silicon micropowder needs to be ground, and when grinding, grinding equipment can not control the whole grinding flow, so that each grinding equipment is independent, and the silicon micropowder is easy to leak, and the working environment is polluted.

Disclosure of Invention

The utility model aims to solve the defects in the prior art and provides a silicon micropowder grinder.

In order to achieve the above purpose, the present utility model adopts the following technical scheme:

the utility model provides a silica powder grinds machine, includes the base and installs the grinding vessel above that, the one end butt joint feed bin of grinding vessel, and one side of grinding vessel is equipped with cyclone, and cyclone passes through the grader and links to each other with the grinding vessel, the other end of grinding vessel links to each other with cyclone through first pipeline, and cyclone's upper end is connected with the dust collection case through the second pipeline.

Preferably, an end cover of the grinding cylinder, which is far away from the storage bin, is provided with a material collecting box, and the material collecting box is communicated with the first pipeline.

Preferably, a filter screen is installed in the material collecting box.

Preferably, two ends of the grinding cylinder are connected with a material pipe, and the material pipe is supported on the base and connected with a driving device on the base.

Preferably, a plurality of spiral blades which are arranged in parallel are connected to the inner wall of the material pipe.

Compared with the prior art, the utility model has the beneficial effects that: the utility model has simple structure, the raw materials enter the grinding cylinder from the bin to be ground, the ground fine particles are sucked into the cyclone separator through the first pipeline under the centrifugal suction force of the cyclone separator and finally enter the dust collecting box to be collected through the second pipeline, meanwhile, the silicon micro powder with larger weight enters the classifier under the action of gravity and then enters the grinding cylinder to be ground again until the ground particle size reaches the requirement.

Drawings

In order to more particularly and intuitively illustrate an embodiment of the present utility model or a technical solution in the prior art, a brief description of the drawings is provided below, which are required to be used in the description of the embodiment or the prior art.

FIG. 1 is a schematic diagram of a structure according to the present utility model;

fig. 2 is an enlarged view of the part a of fig. 1.

In the figure: the device comprises a storage bin 1, a dust collection box 2, a grinding cylinder 3, a cyclone separator 4, a classifier 5, a first pipeline 6, a second pipeline 7, a base 8, a material collection box 9, a filter screen 10, a material pipe 11 and a spiral blade 12.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments.

Referring to fig. 1-2, a silicon micropowder grinder comprises a base 8 and a grinding cylinder 3 arranged on the base, wherein one end of the grinding cylinder 3 is abutted against a storage bin 1, one side of the grinding cylinder 3 is provided with a cyclone separator 4, the cyclone separator 4 is connected with the grinding cylinder 3 through a classifier 5, the other end of the grinding cylinder 3 is connected with the cyclone separator 4 through a first pipeline 6, and the upper end of the cyclone separator 4 is connected with a dust collection box 2 through a second pipeline 7.

In this embodiment, the grinding vessel 3 is kept away from the one end cover of feed bin 1 and is equipped with collection box 9, and collection box 9 and first pipeline 6 intercommunication, collection box 9 play the effect of intercommunication first pipeline 6 and grinding vessel 3, provide the passageway for the material circulation.

In this embodiment, the inside of the collection box 9 is provided with a filter screen 10, and the collection box is discharged from the grinding drum 3 and then filtered by the filter screen 10 to enter the first pipeline 6, thereby playing a role in screening and filtering.

In this embodiment, the both ends of grinding vessel 3 all are connected with material pipe 11, and material pipe 11 supports on base 8 to link to each other with the drive arrangement on the base 8, material pipe 11 is at rotatory in-process, guarantees the entering and the discharge of material, simultaneously, the rotation of liquid level grinding vessel 3 provides the transmission effect.

In this embodiment, the inner wall of the material pipe 11 is connected with a plurality of spiral blades 12 which are arranged in parallel, and in the rotation process of the material pipe 11, the residual silicon micro powder in the material pipe is stirred by the rotation of the spiral blades 12, and enters the grinding cylinder 3 or the filter screen 10, so that the residual silicon micro powder is prevented from being accumulated in the material pipe 11.

In this case, the raw materials get into grinding vessel 3 from feed bin 1 and grind, the tiny granule after grinding is under the effect of cyclone 4 centrifugal suction, inhale cyclone 4 through first pipeline 6 to finally get into dust collection box 2 through second pipeline 7 and collect, the bigger silica flour of counter weight gets into classifier 5 under the effect of gravity simultaneously, reentrant grinding vessel 3 again, until the particle diameter that grinds reaches the needs, this device can once only grind the silica flour raw materials into the silica flour of required particle diameter, realizes once only grinding from the raw materials to the finished product, and efficiency is higher.

The foregoing is only a preferred embodiment of the present utility model, but the scope of the present utility model is not limited thereto, and any person skilled in the art, who is within the scope of the present utility model, should make equivalent substitutions or modifications according to the technical scheme of the present utility model and the inventive concept thereof, and should be covered by the scope of the present utility model.
