Abstract
The utility model discloses a grading device, and in particular discloses a boiling air current crushing and grading device which comprises a crushing chamber and four nozzles arranged in the crushing chamber. The device is characterized in that three nozzles are arranged above the crushing chamber in a regular triangle of mutual spacing 120 degrees, the directions of the nozzles incline downwards from 10 degrees to 40 degrees, the other nozzle jetting air current upwards in a pulse type is installed at the bottom of the crushing chamber and the right lower part of the other three nozzles. The crossing range formed by the air current jetted by the four nozzles is larger, collide opportunity for materials is more, therefore, compared with the prior device, the product produced by adopting the boiling air current crushing and grading device has finer granularity (5000-10000 meshes), more uniform distribution, and more regular shape.
Description
(1) technical field
The utility model relates to a kind of grading plant, particularly a kind of boiling type jet mill grinding device.
(2) background technology
In the material grinding process, gases at high pressure enter Jet Mill, spray through special nozzle to form the ultrahigh speed air-flow, drive through adding the material high-speed motion that feed bin enters, and the material of high-speed motion runs foul of each other, and reaches the purpose of pulverizing.Four nozzles of boiling type jet mill grinding device pulverizing chamber are levels, distribute in opposite directions at present, the crosspoint scope that the air-flow of such four nozzles ejection forms is little, the material collision opportunity is little, and the finished product granularity of production is thin inadequately, skewness, pattern are irregular.
(3) summary of the invention
The utility model provides a kind of and has put rationally, pulverized boiling type jet mill grinding device completely in order to remedy the deficiencies in the prior art.
The utility model is achieved by the following technical solution:
A kind of boiling type jet mill grinding device, comprise four nozzles in pulverizing chamber and the pulverizing chamber, its special character is: wherein three nozzles are the triangular arrangement of spending space 120 above pulverizing chamber, nozzle is directed downwards 10 degree-40 degree that tilt, another make progress the nozzle of pulsed jet-stream wind be installed in pulverizing chamber bottom, three nozzles under.
Operation principle of the present utility model: be provided with the high pressure admission nozzle of arranging in opposite directions around the pulverizing chamber of boiling type jet mill grinding device, penetrate from nozzle, form supersonic flow through purifying with dry compressed air through particular design.Material bumps at high velocity air intersection point center, is pulverized in moment.Particle through pulverizing rises to grading room with air-flow, and qualified particle enters cyclone separator with air-flow, finally obtains required product, and tail gas enters deduster and discharges.
The turbine type hierarchy system that is provided with in grading room can obtain several microns even finer powder.When pulverized material is subjected to the promotion of ascending air in the pulverizing chamber, will be subjected to the effect (i.e. centrifugal intertia force and the gas-flow resistance that produces by the turbine rotation) of two kinds of different power of centrifugal force field at the same particle of turbine rotation section edge.When particle was big, suffered centrifugal force was greater than resistance, and bulky grain flies to the grading room wall along the turbine tangential direction, returns pulverizing chamber then and is pulverized again.When particle hour, this moment centrifugal force less than resistance, granule enters turbine inside with ascending air, is collected as qualified products through cyclone separator.
The utility model adopts four nozzles, and wherein three are triangular form arrangement (space 120 is spent) above pulverizing chamber, and nozzle is directed downwards 10 degree-40 degree, and bottom the another nozzle was installed in, the pulsed jet-stream wind made progress.The crosspoint scope that the air-flow of such four nozzles ejection forms is bigger, and the material collision opportunity is more, therefore adopts the finished product of the utility model production to compare granularity thinner (5000-10000 order) with old device, is more evenly distributed, pattern is more regular.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the schematic top plan view of putting of original nozzle;
Fig. 2 is the perspective diagram of original pulverizing chamber;
Fig. 3 is the schematic top plan view of putting of the utility model nozzle;
Fig. 4 is the perspective diagram of the utility model pulverizing chamber.
Among the figure, 1 pulverizing chamber, 2 nozzles.
(5) specific embodiment
Fig. 1, Fig. 2 are the structure before improving, four nozzles 2 of boiling type jet mill grinding device pulverizing chamber 1 are levels, distribute in opposite directions, the crosspoint scope that the air-flow of such four nozzles, 2 ejections forms is little, the material collision opportunity is little, and the finished product granularity of production is thin inadequately, skewness, pattern are irregular.
Fig. 3, Fig. 4 are a kind of specific embodiment of the present utility model.This embodiment comprises four nozzles 2 in pulverizing chamber 1 and the pulverizing chamber 1, wherein three nozzles 2 are the triangular arrangement of spending space 120 above pulverizing chamber 1, nozzle 2 is directed downwards 10 degree-40 degree that tilt, another make progress the nozzle 2 of pulsed jet-stream wind be installed in pulverizing chamber 1 bottom, three nozzles 2 under.The crosspoint scope that the air-flow of such four nozzles ejection forms is bigger, and the material collision opportunity is more.
Claims (1)
1. boiling type jet mill grinding device, comprise four nozzles (2) in pulverizing chamber (1) and the pulverizing chamber (1), it is characterized in that: wherein three nozzles (2) are arranged at the triangular that pulverizing chamber (1) top is space 120 degree, nozzle (2) is directed downwards 10 degree-40 degree that tilt, another make progress the nozzle (2) of pulsed jet-stream wind be installed in pulverizing chamber (1) bottom, three nozzles (2) under.
