Description

Technical Field

[0001] The present invention relates to the field of air jet mills, and specifically refers to an efficient air jet mill device. Background Art

[0002] An air jet mill device is a mechanical device that uses high-speed air flow to superfine crush powder materials. Its core principle is to accelerate particles through the kinetic energy of the air flow and make them collide with each other, rub against each other, or impact a fixed target surface, thereby achieving the crushing and refinement of the materials.

[0003] The existing air jet mill devices have the following defects: before several portions of powder materials collide with each other and are crushed, each portion of powder material cannot be reciprocally impacted and rubbed first, then continuously collided, and the powder materials collide with each other; it is impossible to fully, efficiently, and continuously process each portion of powder material before it collides with other portions of powder materials, and it is impossible to make several portions of powder materials all meet the required particle size requirements after they collide with each other and are crushed.

[0004] Designing an efficient air jet mill device to address the problems existing in the above-mentioned prior art is the objective of the research of the present invention. Summary of the Invention

[0005] In view of the problems existing in the above-mentioned prior art, the present invention aims to provide an efficient air jet mill device that can effectively solve at least one of the problems existing in the above-mentioned prior art.

[0006] The technical solution of the present invention is as follows: An efficient air jet mill device, comprising: A processing housing, a collection box is arranged on the top end surface of the processing housing, a plurality of guide pipes are arranged around in the processing housing, the plurality of guide pipes are simultaneously communicated with the collection box, a plurality of crushing pipes are arranged around in the processing housing, one end of the crushing pipe is communicated with the guide pipe, the other end of the crushing pipe bends upwards and warps, a plurality of inlet pipes are arranged on the processing housing, one end of the inlet pipe is communicated between the guide pipe and the crushing pipe, and the other end of the inlet pipe penetrates out of the processing housing; several impact flow grinding plates are arranged vertically side by side in the crushing pipe, flow holes are arranged on the impact flow grinding plates, and a plurality of flow holes are arranged staggeredly left and right; the several impact flow grinding plates are used for reciprocally impacting and rubbing the powder material when the high-speed air flow drives the powder material into the crushing pipe. Inside the processing housing and between several of the pulverizing tubes, an uncrushed discharge housing is provided, which is communicated to the outside of the processing housing. Inside the processing housing, several spiral tubes are provided, which are communicatively arranged between the pulverizing tubes and the uncrushed discharge housing. The cross-sectional specification of the spiral tubes gradually decreases towards the uncrushed discharge housing. During the powder that has undergone reciprocating impact and friction enters the spiral tubes, the powder is continuously collided by the inner wall of the spiral tubes and also collides with each other. The several spiral tubes are used to form multiple high-speed airflows in the uncrushed discharge housing with intersecting directions, increased flow velocity, and inclined upward at a predetermined angle.

[0007] Furthermore, between several of the material guiding tubes and the collection box inside the processing housing, a uniform dispersion and pushing device is provided, which is used to uniformly and dispersedly convey the powder in the collection box into each material guiding tube.

[0008] Furthermore, a two-way blade is rotatably arranged in the lower flow hole of the upper and lower two flow holes. A first rotating motor is arranged in the upper impact and friction plate of the upper and lower two impact and friction plates. The first rotating motor is in transmission connection with the two-way blade. A filter screen is arranged above the uppermost impact and friction plate inside the pulverizing tube. The two-way blade is used to continuously rotate and generate an upward airflow when the uniform dispersion and pushing device uniformly and dispersedly conveys the powder in the collection box into each material guiding tube, so as to slap the powder when the high-speed airflow drives the powder through the impact and friction plate, so as to supplement the kinetic energy lost when the high-speed airflow passes through the impact and friction plate. The filter screen is used to intercept the powder that has not reached the predetermined particle size after undergoing reciprocating impact and friction by several impact and friction plates, so as to leave the powder that has not reached the predetermined particle size inside the pulverizing tube. The two-way blade is used to continuously rotate and generate a downward airflow when the uniform dispersion and pushing device does not uniformly and dispersedly convey the powder in the collection box into each material guiding tube, so that the powder that has not reached the predetermined particle size is finally brought downward by the downward airflow between the pulverizing tube and the material guiding tube.

[0009] Furthermore, the uniform dispersion and pushing device includes a connecting seat, which is arranged inside the processing housing. An input pipe is arranged above the connecting seat. The input pipe passes through the processing housing and is communicatively arranged with the collection box. An electromagnetic valve is arranged on the input pipe. A uniformly dispersed arc plate is rotatably arranged on the top end surface of the connecting seat and below the input pipe. An annular groove is arranged on the top end surface of the connecting seat and outside the uniformly dispersed arc plate. Several pushing blocks connected to the uniformly dispersed arc plate are equidistantly arranged in the annular groove. The pushing blocks are located between adjacent two material guiding tubes. A second rotating motor is arranged between the uniformly dispersed arc plate and the connecting seat. The material guiding tube is communicatively arranged with the annular groove.

[0010] Furthermore, an auxiliary discharging device is provided between the processing housing and the uncrushed discharging housing.

[0011] Furthermore, the auxiliary discharging device includes an impeller rotatably arranged at the inner bottom end of the uncrushed discharging housing, and a third rotating motor is arranged between the impeller and the processing housing.

[0012] Furthermore, a nozzle is arranged on the spiral tube and located inside the uncrushed discharging housing.

[0013] Furthermore, the bottom end faces of several of the impact flow grinding plates are all inclined downward with respect to the axis of the pulverizing tube, the planes where the bottom end faces of two adjacent impact flow grinding plates are located intersect, and the angles between the planes where the bottom end faces of two adjacent impact flow grinding plates are located and the axis of the pulverizing tube are the same.

[0014] Furthermore, an air classifier equipment main body is arranged on one side of the processing housing, and the air classifier equipment main body is communicated with the collecting box.

[0015] Therefore, the present invention provides the following effects and / or advantages: 1) The processing housing is used to carry components and has a predetermined accommodation space, and the collecting box is used to accommodate and store powder materials.

[0016] A plurality of the inlet pipes are simultaneously connected to external equipment. The inlet pipes are used to input high-speed air flow between the guide pipe and the pulverizing tube when the powder materials in the collecting box are conveyed to each guide pipe, so as to accelerate the flow of the powder materials towards the pulverizing tube when the powder materials enter the guide pipe, thereby preventing the powder materials from adhering to the inner wall of the guide pipe and not entering the pulverizing tube, and thus increasing the initial kinetic energy of the materials when they enter the pulverizing tube.

[0017] Several of the impact flow grinding plates are used to make the powder materials be repeatedly impacted and rubbed during the period when the high-speed air flow drives the powder materials into the pulverizing tube, so that the powder materials are pulverized to a predetermined particle size; during the period when the high-speed air flow drives the powder materials into the pulverizing tube, the powder materials cannot completely follow the high-speed air flow due to inertia and impact the impact flow grinding plates to be pulverized, and the pulverized powder materials are rubbed against the bottom end faces of the impact flow grinding plates when flowing with the high-speed air flow to be pulverized; the flow holes are used for the high-speed air flow to drive the powder materials through the impact flow grinding plates.

[0018] During the period when the powder material that has undergone reciprocating impacts and frictions by several impact-flow grinding plates enters the spiral tube, the powder material is continuously collided by the inner wall of the spiral tube and also collides with each other. Since the cross-sectional specification of the spiral tube gradually decreases towards the uncrushed discharge housing, the intensity of the continuous collision of the powder material by the inner wall of the spiral tube gradually increases, and the frequency of the collision between the powder materials gradually increases. As a result, the powder materials all meet the particle size requirements when entering the uncrushed discharge housing; when the powder material that has undergone reciprocating impact crushing and friction crushing by several impact-flow grinding plates enters the uncrushed discharge housing through the spiral tube, a high-speed air flow with an increased flow rate and inclined upward at a predetermined angle is formed; several of the said spiral tubes are used to form multiple high-speed air flows with intersecting directions, increased flow rates, and inclined upward at a predetermined angle within the uncrushed discharge housing. Thus, at the intersection of the multiple high-speed air flows, the powder materials first collide with each other and are crushed and then move upward to the outside of the processing housing.

[0019] In summary: Before the several portions of powder materials collide with each other and are crushed, each portion of powder material can first be reciprocally impacted and rubbed, then continuously collided, and also collide with each other; it can enable each portion of powder material to be fully, efficiently, and continuously processed before colliding with other portions of powder materials, and can enable several portions of powder materials to all meet the required particle size requirements after colliding with each other and being crushed.

[0020] 2) The uniform dispersion pushing device is used to uniformly and dispersedly convey the powder material in the collection box into each guide pipe, preventing the agglomerated powder material from entering the guide pipe and being unable to be fully crushed when the powder material is crushed, ensuring the continuous entry of the powder material into the guide pipe, and preventing the occurrence of bridging phenomenon when the powder material enters the guide pipe, which may cause the powder material to be unable to be continuously crushed.

[0021] 3) The two-way blades are used to continuously rotate under drive and generate an upward air flow when the uniform dispersion pushing device uniformly and dispersedly conveys the powder material in the collection box into each guide pipe, so as to slap the powder material when the high-speed air flow drives the powder material through the impact-flow grinding plates, thereby causing the powder material to be crushed, to supplement the kinetic energy lost by the high-speed air flow when passing through the impact-flow grinding plates, and thus ensuring that the effect of the powder impacting and rubbing against the impact-flow grinding plates will not significantly decrease when the high-speed air flow drives the powder material to flow upward.

[0022] The filter screen is used to intercept the powder material that has undergone reciprocating impacts and frictions by several impact-flow grinding plates but has not reached the predetermined particle size, so as to leave the powder material that has not reached the predetermined particle size in the crushing pipe.

[0023] The two-way blades are used to continuously rotate under drive and generate a downward air flow when the powder in the collection box is not evenly and dispersedly conveyed to each guide pipe by the uniform dispersion feeding device, so that the powder that does not reach the predetermined particle size is finally carried downward by the air flow to between the pulverizing pipe and the guide pipe. Thus, when the powder in the collection box is evenly and dispersedly conveyed to each guide pipe by the uniform dispersion feeding device, it flows along with the high-speed air flow and is repeatedly impacted and rubbed by several impact flow grinding plates until it reaches the predetermined particle size.

[0024] 4) The feeding pipe is used to convey the powder in the collection box above the uniform dispersion arc plate. The solenoid valve is used to control the powder to be discharged at a predetermined flow rate when the feeding pipe conveys the powder in the collection box above the uniform dispersion arc plate. The uniform dispersion arc plate is used to receive the powder when the solenoid valve controls the powder to be discharged at a predetermined flow rate. The second rotating motor is used to drive the uniform dispersion arc plate to rotate uniformly when the uniform dispersion arc plate receives the powder, so as to centrifugally disperse the powder evenly into the annular groove, preventing the agglomerated powder from entering the guide pipe and not being fully pulverized when the powder is pulverized; several pushing blocks are used to follow the movement of the uniform dispersion arc plate to continuously push the powder into each guide pipe when the powder is centrifugally dispersed evenly into the annular groove, so as to ensure the continuous entry of the powder into the guide pipe and prevent the powder from bridging when entering the guide pipe, resulting in the inability to continuously pulverize the powder.

[0025] 5) The auxiliary output device is used to generate an upward air flow during the upward movement of the powder to the outside of the processing shell, so as to accelerate the movement of the powder to the outside of the processing shell, thereby reducing the adhesion of the powder to the inner wall of the uncrushed discharge shell.

[0026] 6) The nozzle is used to further increase the flow rate of the air flow whose flow rate has been increased by the spiral pipe, so that the mutual collision of the powder at the intersection of multiple high-speed air flows is more intense, thereby increasing the pulverizing effect on the powder.

The objectives and other advantages of the present invention are achieved and obtained by the structures specifically pointed out in the description and the drawings.

[0033] For the convenience of those skilled in the art to understand, the embodiments will now be further described in detail in conjunction with the drawings for the structure of the present invention: Refer to Figures 1-3 , a high-efficiency jet mill equipment, comprising: Processing housing 2, a collecting box 3 is arranged on the top end surface of the processing housing 2, several feeding pipes 4 are arranged around the inside of the processing housing 2, several of the feeding pipes 4 are simultaneously communicated with the collecting box 3, the processing housing 2 is used for carrying components and has a predetermined accommodation space, the collecting box 3 is used for accommodating and storing powder materials, several pulverizing pipes 5 are arranged around the inside of the processing housing 2, one end of the pulverizing pipe 5 is communicated with the feeding pipe 4, the other end of the pulverizing pipe 5 bends upwards, the pulverizing pipe 5 is located inside the feeding pipe 4, several inlet flow pipes 6 are arranged on the processing housing 2, one end of the inlet flow pipe 6 is communicated between the feeding pipe 4 and the pulverizing pipe 5, the other end of the inlet flow pipe 6 penetrates out of the processing housing 2; several of the inlet flow pipes 6 are simultaneously connected to external equipment, the inlet flow pipe 6 is used for inputting high-speed air flow between the feeding pipe 4 and the pulverizing pipe 5 when the powder materials in the collecting box 3 are conveyed to each feeding pipe 4, so as to accelerate the flow of the powder materials towards the pulverizing pipe 5 when the powder materials enter the feeding pipe 4, thereby preventing the powder materials from adhering to the inner wall of the feeding pipe 4 and not entering the pulverizing pipe 5, so that the initial kinetic energy of the materials is increased when entering the pulverizing pipe 5; several impact flow grinding plates 7 are arranged vertically side by side inside the pulverizing pipe 5, flow-through holes 8 are arranged on the impact flow grinding plate 7, several of the flow-through holes 8 are arranged staggered left and right; several of the impact flow grinding plates 7 are used for making the powder materials be reciprocally impacted and rubbed during the period when the high-speed air flow drives the powder materials into the pulverizing pipe 5, so that the powder materials are pulverized to a predetermined particle size; during the period when the high-speed air flow drives the powder materials into the pulverizing pipe 5, the powder materials cannot completely follow the high-speed air flow due to inertia and impact the impact flow grinding plate 7 to be pulverized, and the pulverized powder materials are rubbed with the bottom end surface of the impact flow grinding plate 7 when flowing with the high-speed air flow to be pulverized; the flow-through hole 8 is used for the high-speed air flow to drive the powder materials through the impact flow grinding plate 7 Inside the processing housing 2 and disposed between several of the pulverizing tubes 5 is an uncrushed discharge housing 9. The uncrushed discharge housing 9 communicates to the outside of the processing housing 2. Inside the processing housing 2 are provided several spiral tubes 10. The spiral tubes 10 are communicatively disposed between the pulverizing tubes 5 and the uncrushed discharge housing 9. The cross-sectional specification of the spiral tubes 10 gradually decreases towards the uncrushed discharge housing 9. During the period when the powder that has undergone reciprocating impacts and friction by several impact flow grinding plates 7 enters the spiral tubes 10, the powder is continuously impacted by the inner wall of the spiral tubes 10 and the powder particles collide with each other. Since the cross-sectional specification of the spiral tubes 10 gradually decreases towards the uncrushed discharge housing 9, the intensity of the continuous impact of the powder by the inner wall of the spiral tubes 10 gradually increases, and the frequency of mutual collisions between the powder particles gradually increases, so that the powder meets the particle size requirements when entering the uncrushed discharge housing 9. When the powder that has undergone reciprocating impact crushing and friction crushing by several impact flow grinding plates 7 enters the uncrushed discharge housing 9 through the spiral tubes 10, a high-speed air flow with an increased flow rate and inclined upward at a predetermined angle is formed. The several spiral tubes 10 are used to form multiple high-speed air flows in the uncrushed discharge housing 9 with intersecting directions, increased flow rates, and inclined upward at a predetermined angle. Thus, at the intersection of the multiple high-speed air flows, the powder particles first collide with each other and are crushed and then move upward to the outside of the processing housing 2.

[0034] Inside the processing housing 2 and disposed between several of the material guiding tubes 4 and the collecting box 3 is a uniform dispersion pushing device. The uniform dispersion pushing device is used to uniformly and dispersedly convey the powder in the collecting box 3 into each material guiding tube 4, prevent the agglomerated powder from entering the material guiding tube and being unable to be fully crushed when the powder is pulverized, ensure the continuous entry of the powder into the material guiding tube, and prevent the powder from bridging when entering the material guiding tube, resulting in the inability of the powder to be continuously pulverized.

[0035] Rotatably disposed in the lower flow hole 8 of the upper and lower two flow holes 8 is a two-way blade 11. Inside the upper impact flow grinding plate 7 of the upper and lower two impact flow grinding plates 7 is a first rotating motor 12. The first rotating motor 12 is in transmission connection with the two-way blade 11. Inside the pulverizing tube 5 and above the uppermost impact flow grinding plate 7 is a filter screen 13; The two-way blade 11 is used to be continuously rotated by driving and generate an upward air flow when the uniform dispersion pushing device uniformly and dispersedly conveys the powder in the collecting box 3 into each material guiding tube 4, so as to slap the powder when the high-speed air flow drives the powder through the impact flow grinding plate 7, thereby pulverizing the powder, to supplement the kinetic energy lost by the high-speed air flow when passing through the impact flow grinding plate 7, so as to ensure that the effect of the powder impacting and rubbing against the impact flow grinding plate 7 does not decrease significantly when the high-speed air flow drives the powder to flow upward; The filter screen 13 is used to intercept the powder materials that have not reached the predetermined particle size after being repeatedly impacted and rubbed by several impact flow grinding plates 7, so as to keep the powder materials that have not reached the predetermined particle size in the crushing pipe 5; The two-way blades 11 are used to continuously rotate and generate a downward air flow when the powder materials in the collection box 3 are not evenly and dispersedly conveyed to each guide pipe 4 by the uniform dispersion feeding device, so that the powder materials that have not reached the predetermined particle size are finally brought to between the crushing pipe 5 and the guide pipe 4 by the downward air flow. Thus, when the powder materials in the collection box 3 are evenly and dispersedly conveyed to each guide pipe 4 by the uniform dispersion feeding device, they flow along with the high-speed air flow and are repeatedly impacted and rubbed by several impact flow grinding plates 7 until they reach the predetermined particle size.

[0036] The uniform dispersion feeding device includes a connecting seat 14, which is arranged in the processing housing 2. Above the connecting seat 14, there is a feeding pipe 15. The feeding pipe 15 passes through the processing housing 2 and is communicated with the collection box 3. An electromagnetic valve 16 is arranged on the feeding pipe 15.

[0037] The feeding pipe 15 is used to convey the powder materials in the collection box 3 above the uniform dispersion arc plate 17. The electromagnetic valve 16 is used to control the powder materials to be discharged at a predetermined flow rate when the feeding pipe 15 conveys the powder materials in the collection box 3 above the uniform dispersion arc plate 17. The uniform dispersion arc plate 17 is used to receive the powder materials when the electromagnetic valve 16 controls the powder materials to be discharged at a predetermined flow rate. The second rotating motor 20 is used to drive the uniform dispersion arc plate 17 to rotate uniformly to centrifugally disperse the powder materials evenly into the annular groove 18 when the uniform dispersion arc plate 17 receives the powder materials, preventing the agglomerated powder materials from entering the guide pipe 4 and not being fully crushed when the powder materials are crushed; several pushing blocks 19 are used to follow the movement of the uniform dispersion arc plate 17 to continuously push the powder materials into each guide pipe 4 when the powder materials are centrifugally dispersed into the annular groove 18 evenly, so as to ensure the continuous entry of the powder materials into the guide pipe 4 and prevent the powder materials from bridging when entering the guide pipe 4 and causing the powder materials to be unable to be continuously crushed.

[0038] A secondary output device is arranged between the processing housing 2 and the uncrushed discharge housing 9.

[0039] The auxiliary discharging device is used to generate an upward air flow during the upward movement of the powder material to the outside of the processing housing 2 to accelerate the movement of the powder material to the outside of the processing housing 2, thereby reducing the adhesion of the powder material to the inner wall of the uncrushed discharging housing 9.

[0040] The auxiliary discharging device includes an impeller 21 rotatably arranged at the inner bottom end of the uncrushed discharging housing 9, and a third rotating motor 22 is arranged between the impeller 21 and the processing housing 2.

[0041] A nozzle 23 is arranged on the spiral tube 10 and inside the uncrushed discharging housing 9.

[0042] The nozzle 23 is used to further increase the flow rate of the air flow whose flow rate has been increased by the spiral tube 10 so that the mutual collision of the powder material at the intersection of multiple high-speed air flows is more intense, thereby enhancing the pulverizing effect on the powder material.

[0043] The bottom end surfaces of several impact flow grinding plates 7 are all inclined downward with respect to the axis of the pulverizing tube 5, the planes where the bottom end surfaces of two adjacent impact flow grinding plates 7 are located intersect, and the angles between the planes where the bottom end surfaces of two adjacent impact flow grinding plates 7 are located and the axis of the pulverizing tube 5 are the same.

[0044] During the period when the high-speed air flow drives the powder material into the pulverizing tube, the powder material is fully and efficiently reciprocally impacted and rubbed by several impact flow grinding plates 7, reducing the number of powder materials that cannot be pulverized to the predetermined particle size.

[0045] An air jet mill equipment main body 1 is arranged on one side of the processing housing 2, and the air jet mill equipment main body 1 is communicated with the collecting box 3. The air jet mill equipment main body 1 is used to crush the powder material and discharge it into the collecting box 3 so that the collecting box 3 can accommodate and store the powder material.
