Description
Technical Field
The utility model relates to the field of fluidized bed jet mills, in particular to a material accumulation preventing fluidized bed jet mill.
Background
Fluidized bed fluid energy mill is through being located the lower part and smashing the chamber nozzle and jet out high-speed air current and accelerate the raw materials granule that adds the chamber to the granule collides mutually and is smashed, then rises to hierarchical intracavity and regulates and control ejection of compact granularity through the gradation wheel rotational speed, and qualified farine can follow the discharging pipe ejection of compact, and unqualified powder can fall back and smash the chamber and continue to smash. When the equipment of present mainstream is using, just can appear smashing the effect after the material that needs to smash intracavity lower cone accumulates a certain material level height, so can cause the material to lead to smashing repeatedly grinding sometimes, also can appear some viscidity material reunion and pile up, just need to shut down the clearance for a period of time.
Disclosure of Invention
The utility model aims to provide a material accumulation preventing fluidized bed jet mill.
The innovation point of the utility model is that the fan blows the materials deposited at the bottom of the crushing cavity, the materials are not easy to accumulate at the bottom, the materials at the bottom can easily reach the collision point of the side nozzle, and the materials can be crushed without accumulating to a certain height.
In order to realize the purpose of the utility model, the technical proposal of the utility model is as follows: the utility model provides a prevent long-pending material fluidized bed fluid energy mill, is including smashing the chamber, it is equipped with the side nozzle to smash the chamber lateral wall, it is equipped with the fan to smash the chamber bottom, is equipped with drive fan pivoted drive shaft on the fan, and drive shaft one end is stretched out and is smashed the chamber and be connected with driving motor. The fan blows the materials deposited at the bottom of the crushing cavity, the materials are crushed along with the air flow and are not agglomerated, and the condition of wall sticking and material accumulation is not easy to occur.
Furthermore, smash the chamber bottom and be equipped with the access cover, driving motor fixes on the access cover. When the fan needs to be maintained, the maintenance cover is directly opened, and the operation is fast.
Furthermore, the bottom of the crushing cavity is of a small hemispherical structure, and an air jet is arranged at the joint of the bottom of the crushing cavity and the side wall and enters from the tangential direction of the small hemispherical structure and faces the bottom of the crushing cavity. The volume of the small hemisphere structure is small, the surface is smooth and has no dead angle, and the amount of materials deposited at the bottom is reduced; the air jet blows air, and materials deposited at the bottom of the crushing cavity are easily sprayed to the fan and blown up by the fan, so that the materials reach the collision point of the side nozzle and are crushed.
Further, two or more pairs of side nozzles are distributed, wherein one pair of side nozzles are obliquely arranged downwards, and the other side nozzles are horizontally arranged. The final collision point of the side nozzle inclining downwards is still near the center, but the side nozzle is properly descended compared with the side nozzle arranged horizontally, the crushing effect is not different from that of the original structure, but due to the downward inclination, the collided air flow has a vertical downward component force, the downward flowing air flow reflows along the inside of the cavity under the action of the fan to form a fully fluidized space, so that the crushed raw materials can be crushed without being accumulated to a certain material position, and the viscous materials can be prevented from being accumulated for a long time and being washed by the air flow, and the problem of wall sticking and material accumulation can be reduced.
Furthermore, a rubber scraper tightly attached to the bottom of the crushing cavity is fixedly connected to the driving shaft. When the fan rotates, the driving shaft drives the rubber scraper to rotate, and the bottom of the crushing cavity of the rubber scraper cleans materials adhered to the wall.
The utility model has the beneficial effects that:
1. according to the utility model, the fan blows the materials deposited at the bottom of the crushing cavity, the materials are not easy to accumulate at the bottom, the materials at the bottom can easily reach the collision point of the side nozzle, and the materials can be crushed without accumulating to a certain height.
2. The small hemisphere structure has small volume, smooth surface and no dead angle, and the amount of materials deposited at the bottom is reduced; the air jet blows air, and materials deposited at the bottom of the crushing cavity are easily sprayed to the fan and blown up by the fan, so that the materials reach the collision point of the side nozzle and are crushed.
3. When the fan rotates, the driving shaft drives the rubber scraper to rotate, and the rubber scraper crushes the wall-sticking materials at the bottom of the cavity.
Drawings
FIG. 1 is a schematic structural diagram of the present invention.
Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
Example 1: as shown in fig. 1, a prevent long-pending material fluidized bed fluid energy mill, including smashing chamber 1, it is equipped with side nozzle 2 to smash 1 lateral wall in chamber, side nozzle 2 has laid two pairs or more than two pairs, wherein the slope of a pair of side nozzle 2 is arranged downwards, all the other side nozzles 2 levels are arranged, it is equipped with fan 3 to smash 1 bottom in chamber, be equipped with 3 pivoted drive shaft 4 of drive fan on the fan 3, it hugs closely the rubber scraper 5 who smashes 1 bottom in chamber to go back fixedly connected with on the drive shaft 4, drive shaft 4 one end is stretched out and is smashed chamber 1 and be connected with driving motor 6, it is equipped with access cover 7 to smash 1 bottom in chamber, driving motor 6 is fixed on access cover 7, it is little hemisphere structure to smash 1 bottom in chamber, the junction of smashing 1 bottom and lateral wall is equipped with air jet 8, air jet 8 gets into and smashes 1 bottom in chamber from little hemisphere structure's tangential direction and towards.
When the device works, materials are put into the crushing cavity 1, the horizontal side nozzles 2 spray air flow, the materials are crushed in a fluidized state along with the air flow, the bottom driving motor 6 drives the driving shaft 4 to rotate, the fan 3 and the rubber scraper 5 rotate along with the driving shaft 4, the rubber scraper 5 scrapes wall-sticking materials, the driving fan 3 blows the bottom materials, the air jet 8 also sprays the air flow, the materials are not easy to deposit at the bottom of the crushing cavity 1, the final collision point of the side nozzles 2 which are inclined downwards is still near one point at the center, but the crushing effect is not different from the original structure when being compared with the side nozzles 2 which are horizontally arranged, but the air flow after collision has a vertical downward component due to downward inclination, the air flow which flows downwards flows back along the inside of the cavity under the action of the fan, a fully fluidized space is formed, and the crushed raw materials can not be crushed until a certain material level, viscous materials can not be accumulated for a long time and have airflow scouring, and the problem of wall sticking and material accumulation can be reduced.
The described embodiments are only some embodiments of the utility model, not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
