Detailed Description
As shown in fig. 1-4, the following is a specific embodiment of the present utility model and the technical scheme of the present utility model is further described with reference to the accompanying drawings, but the present utility model is not limited to these embodiments, and the present utility model includes a conical cylinder 1, and further includes a bottom plate 2 disposed at the bottom surface of the conical cylinder 1, a top plate 3 disposed at the top surface of the conical cylinder 1, a nozzle 4 penetrating through the wall of the conical cylinder 1, a nozzle 5 disposed at the air outlet end of the nozzle 4, a grinding mechanism for grinding powder disposed along the tangential direction of the nozzle 5, the grinding mechanism including a rotation shaft 6 rotatably mounted between the top plate 3 and the bottom plate 2 through a bearing, the rotation shaft 6 being parallel to the central axis of the conical cylinder 1, a grinding wheel 7 disposed on the rotation shaft 6 and movably mounted with the rotation shaft, the conical surface of the grinding wheel 7 being consistent with the conical surface of the conical cylinder 1, the conical surface of the grinding wheel 7 being divided into a plurality of steps, fan blades 8 disposed between the first step and the second step, the fan blades 8 being fixedly mounted with the top plate 7, the fan blades 8 being disposed at the necked-down sections of the grinding wheel 7, the fan blades 8 being smaller than the diameter of the top surface of the adjacent step 7, a diameter of the fan blades being smaller than the top surface of the two step, the top plate 7 being disposed between the first step 7 and the bottom surface of the grinding wheel 7 and the bottom plate 3 being disposed with a spring 11 being disposed between the bottom surface of the grinding wheel 7 and the grinding wheel being not being in the same order as the top plate 11, and being disposed between the top plate and the top plate is disposed between the top plate 3 and the grinding wheel is disposed by a top plate 11 being convenient.
In this embodiment, the air inlet end of the spray pipe 4 is connected with a first-stage air flow pipe 12, the negative pressure part of the throat of the first-stage air flow pipe 12 is connected with a second-stage air flow pipe 13, the negative pressure part of the throat of the second-stage air flow pipe 13 is provided with a feeding hopper 14, and the first-stage air flow pipe 12 and the second-stage air flow pipe 13 are venturi pipes, and the principle is that when the air flow passes through the narrow throat of the pipeline, the air flow can be accelerated due to the restriction of the throat, the throat and the air inlet end of the air inlet pipe form a negative pressure difference, and when the air flow speed of the air inlet end of the air inlet pipeline is increased, the throat forms a larger negative pressure suction force.
When the powder grinding operation is needed, the power supply of the air compressor, the dryer and the powder air flow grinder is started, the high-pressure air flow processed by the compressor, the air storage tank, the freeze dryer and the precise filter enters the air inlet end of the first-stage air flow pipe 12, meanwhile, the powder vacuum feeder starts to feed the powder into the feeding hopper 14, the negative pressure part of the first-stage air flow pipe 12 sucks the powder from the feeding hopper 14 and mixes the powder with the air flow to form an air flow mixture, the air flow mixture enters the negative pressure part of the second-stage air flow pipe 13 and is mixed with the air flow of the second-stage air flow pipe 13, the mixed air flow is further enhanced, the mixed air flow is sprayed out from the nozzle 5, the high-pressure air flow mixture rotates along the tangential direction of the inner wall of the cone and is blown to the fan blades 8, the fan blades 8 rotate under the force to drive the grinding wheel 7 to rotate, the fan blade 8 rotates and generates upward thrust so as to drive the grinding wheel 7 to move upwards along the rotating shaft for a certain distance, the top surface of the grinding wheel 7 extrudes the first spring 9, the first spring 9 generates a reverse acting force on the top surface of the grinding wheel 7, the grinding wheel 7 moves downwards under the action of gravity and spring reaction force, when the bottom surface of the grinding wheel 7 compresses the second spring 10, the second spring 10 generates an upward buffering force on the grinding wheel 7, the grinding wheel 7 moves continuously and axially up and down along the rotating shaft 6, and the circulation is repeated, so that the grinding wheel 7 rotates continuously and moves up and down, the conical surface of the rotating grinding wheel 7 and the conical surface of the conical cylinder 1 are separated from each other, and the purpose of powerful grinding of medicinal powder passing through the contact surface of the two is achieved.
After the air flow sprayed from the nozzle 5 impacts the surface of the grinding wheel 7, after the high-pressure air flow mixture is primarily impacted, one part of the air flow mixture passes through the grinding wheel 7 and the grinding surface of the conical cylinder 1 to be ground, the other part of the air flow mixture passes through the necking part of the grinding wheel 7 to continue rotating, one part of the air flow mixture is further scattered and decomposed along the concave-convex surface of the conical cylinder 1, the rotating air flow impacts the next grinding wheel 7, the finer powder particles are brought to the central discharging pipe 11 to be discharged to the cyclone separator under the action of centrifugal force, and the larger particles continue grinding along the tangential direction.
