Description

Technical Field

[0001] The present invention relates to the technical field of air flow mills, and specifically refers to a high-efficiency air flow mill equipment, which can grind and lift materials deposited in a grinding chamber as needed, and can effectively solve the problem of material blockage in the classifying wheel, thereby significantly improving the material grinding effect and grinding efficiency. Background Art

[0002] A jet mill utilizes high-speed airflow to grind the surface of materials. This process utilizes the high-speed rotating flow field generated by the airflow, causing the material to continuously rotate, collide, and rub against each other, thereby grinding and pulverizing the material. Existing jet mills are equipped with a classifying wheel on top. This wheel is driven by a classifying motor. Materials that meet the required particle size are classified by the classifying wheel and discharged through the corresponding discharge pipe. Materials that do not meet the required particle size are returned to the mill's grinding chamber for further pulverization.

[0003] The existing classifying wheel for air flow mill generally includes a fixed plate that is connected to the output shaft end of the classifying motor. A plurality of spacers are arranged at intervals on the fixed plate. The gaps between two adjacent spacers are used to classify the material. The material that meets the particle size requirements enters the classifying wheel through the gaps between the two adjacent spacers and is discharged along the corresponding discharge pipe. Since the material is easily attached to the spacers when flowing between the two adjacent spacers, the problem of material blockage often occurs as the running time of the classifying wheel increases. Moreover, since some materials with larger particles are easily deposited in the crushing chamber on the lower side of the crushing nozzle when being thrown downward by the classifying wheel, in order to improve the crushing effect, it is necessary to grind and lift this part of the material, so as to lift the deposited material upward and re-enter the high-pressure airflow for re-crushing. However, this lifting process will significantly increase the concentration of the material in a short period of time, thereby causing a significant increase in the blocking rate of the classifying wheel, which is very troublesome.

[0004] Therefore, the purpose of this invention is to design a highly adaptable air flow mill that can effectively grind and lift the deposited materials on demand, and can automatically clear the grading wheel, thereby effectively preventing the grading wheel from being significantly blocked, so as to ensure that the materials that meet the particle size requirements can be continuously and effectively output smoothly, thereby significantly improving the crushing effect and efficiency of the materials. Summary of the Invention

[0005] In view of the technical problems existing in the above-mentioned prior art, the present invention provides a high-efficiency air flow mill device, which can effectively solve the technical problems existing in the above-mentioned prior art.

[0006] The technical solution of the present invention is:

[0007] A high-efficiency air jet mill device, comprising:

[0009] The crushing mechanism includes a plurality of crushing nozzles and a grinding disc arranged at different heights on the lower side of the crushing chamber. Compressed air is transmitted through the crushing nozzles to form a supersonic airflow to cause the material to collide and crush. A plurality of crushing pieces are arranged alternately up and down on the periphery of the grinding disc. Driven by a corresponding drive motor, the grinding disc drives the crushing pieces to grind and lift the material deposited at the bottom of the crushing chamber.

[0010] A grading wheel is disposed in the sorting chamber and driven by a corresponding grading motor.

[0011] The blockage clearing mechanism includes a support ring plate fixed to the inner side of the middle part of the partition, and a support shaft fixed to the center of the fixed plate. The end of the support shaft is equipped with a support member through a one-way bearing. The outer end of the support member can be movably abutted against the support ring plate. The outer end of the support member is fixed with elastic paddles on both sides extending between two adjacent partitions.

[0012] The support members are arranged in a cross shape, and the outer ends of the support members are respectively rollingly mounted with support balls whose outer ends abut against the support ring plate.

[0013] The sorting chamber of the air flow mill body is externally connected to a discharge pipe, and the upper part of the crushing chamber of the air flow mill body is externally connected to a feed pipe; a corresponding annular air bag is fixedly sleeved on the air flow mill body, and the annular air bag is connected to an external air compressor, and the crushing nozzle is connected to the annular air bag through a corresponding conducting pipe.

[0014] One end of the spacer that is not fixed to the fixed plate is fixed with a connecting ring plate that is located in the discharge pipe and is arranged with a gap between the discharge pipe and the spacer.

[0015] The support mechanism includes a plurality of support columns evenly distributed in an annular shape around the air flow mill body, the upper ends of the support columns are respectively fixedly installed with corresponding electronic scales, the outer side walls of the air flow mill body are respectively fixed outward with corresponding ear plates corresponding to the support columns, and the ends of the ear plates not connected to the air flow mill body are respectively installed on the electronic scales, so that the air flow mill body can be mounted on the support columns in a weighable manner; when the total weight values ​​obtained by the electronic scales reaches the set value G1, the drive motor starts and turns off until the total weight values ​​obtained by the electronic scales are lower than the set value G2.

[0016] The top end portion of each supporting plate is movably mounted on the support frame, and the bottom end portion of each supporting plate is movably mounted on the support frame, and the top end portion of each supporting plate is movably mounted on the support frame.

[0017] The fixing members are respectively provided with corresponding locking long holes, and the mounting plate after the height adjustment is completed is fixed and locked on the locking long holes of the fixing members by cooperating with corresponding locking bolts and corresponding washers.

[0018] The middle of the driving shaft is rotatably mounted with a corresponding supporting sleeve, and the bottom of the mounting groove of the fixing member is fixedly connected upward with a fixing convex edge for supporting the supporting sleeve.

[0019] The ends of the ear plates that are not connected to the air flow mill body are respectively fixed downward with corresponding fixed box bodies, and the bottoms of the ear plates respectively extend through and extend above the bottom of the fixed box bodies, and the bottoms of the ear plates are respectively rotatably mounted with corresponding connecting balls, and the bottom ends of the connecting balls respectively roll and abut against the bottoms of the corresponding fixed box bodies, and the fixed box bodies are respectively filled with a number of corresponding damping particles for vibration reduction, and corresponding locking plates are respectively provided on both sides of the fixed box bodies, and the locking plates are fixed to the corresponding electronic scales by corresponding locking bolts.

[0020] The spacers are integrally formed at positions corresponding to the support ring plates and are provided with corresponding reinforcing ribs inwardly. The reinforcing ribs are concavely provided with slots for embedding the support ring plates, and the outer ends of the elastic picks are set into a shape adapted to the reinforcing ribs and the spacers.

[0021] Advantages of the present invention:

[0022] 1) Based on the existing pulverizing nozzle, the present invention adds a grinding cutter disc. Driven by a corresponding drive motor, the grinding cutter disc drives the crushing pieces to grind and lift the materials deposited at the bottom of the pulverizing chamber as needed;

[0023] The present invention is provided with a blocking removal mechanism on the basis of the existing classifying wheel, which includes a support ring plate fixedly connected to the inner side of the middle part of the spacer and a support shaft fixedly connected to the center of the fixed plate. The support ring plate is used to strengthen the support of the spacer, and the support shaft is used to cooperate with the one-way bearing to realize the one-way rotation installation of the support member. The support of the spacer can be further improved by the movable abutment between the support member and the support ring plate. Since the support member is unidirectionally rotatably mounted on the support shaft, when the classifying motor stops, when the classifying wheel connected to the output shaft end of the classifying motor decelerates rapidly, the support member unidirectionally rotatably mounted on the support shaft continues to rotate rapidly around the support shaft under the action of inertia, thereby forming a rotation speed difference with the classifying wheel, so as to drive the elastic paddle to pry each spacer to clear the blockage, thereby realizing automatic clearing of the classifying wheel, thereby effectively preventing the classifying wheel from being significantly blocked, and effectively ensuring that materials that meet the particle size can be continuously and effectively output smoothly, thereby significantly improving the material crushing effect and crushing efficiency.

[0024] 2) The support member of the present invention is arranged in a cross shape, and the outer ends of the support members are respectively rollingly installed with support balls whose outer ends abut against the support ring plate. Through the intervention of the support balls, the rolling connection between the support member and the support ring plate is achieved, which can not only maintain the supporting effect of the support member on the support ring plate, but also reduce the friction when there is a speed difference between the two, so as to effectively ensure the practical effect of the present invention.

[0025] 3) The upper ends of the support columns of the present invention are respectively fixedly mounted upward with corresponding electronic scales, and the outer side walls of the airflow mill body corresponding to the support columns are respectively fixedly connected outward with corresponding ear plates, and the ends of the ear plates not connected to the airflow mill body are respectively mounted on the electronic scales. When the total weight values ​​obtained by the electronic scales reaches the set value G1, it can be determined that the amount of material deposited at the bottom of the crushing chamber is relatively large. At this time, the drive motor starts to drive the grinding disc and crushing pieces to grind and lift the material deposited at the bottom of the crushing chamber until the total weight values ​​obtained by the electronic scales are lower than the set value G2, and then the motor is turned off, thereby effectively and accurately controlling the lifting process, so that the material deposited at the bottom of the crushing chamber can be ground and lifted as needed.

[0026] 4) The outer side walls of the air flow mill body of the present invention are respectively fixed with fixing parts corresponding to the ear plates, and the outer sides of the fixing parts are respectively provided with corresponding embedding grooves, and the ends of the ear plates are respectively fixed with mounting plates adapted to the embedding grooves of the fixing parts, and a driving shaft is rotatably mounted on the bottom side of the fixing parts, and driving threads with opposite rotation directions are respectively provided on both sides of the driving shaft, and corresponding support guide blocks are movably mounted on both sides of the driving shaft through threaded connections, and the upper ends of the support guide blocks are respectively provided with inwardly inclined surfaces, and the bottom ends of both sides of the mounting plates are respectively provided with inclined surfaces adapted to the upper ends of the support guide blocks, and are provided with inverted T-shaped slots for movably engaging the support guide blocks. In order to ensure the crushing effect and weighing accuracy of the material, the installation position of each ear plate used for the installation of the air flow mill body must have high accuracy requirements. Therefore, it is necessary to adjust the installation height of each ear plate. By rotating the drive shaft of the present invention, the support guide blocks can be synchronously driven to move toward or away from each other, and then the installation plate can be driven up or down to achieve convenient and high-precision adjustment of the installation height of each ear plate.

[0027] 5) The drive shafts of this invention each have a corresponding support sleeve rotatably mounted in the middle. The bottom of the mounting groove of the fixing member is fixed upwardly with a fixed flange that supports the support sleeve. The intervention of the support sleeve and the fixed flange ensures support for the drive shaft, thereby preventing excessive deformation of the drive shaft and maintaining the practical effect of this invention.

[0028] 6) Since there is a significant amount of vibration during the material crushing process, it will have a negative impact on the weighing accuracy. Therefore, it is necessary to perform vibration reduction and vibration isolation treatment on each ear plate. The ear plate of the present invention is not connected to the end of the air flow mill body and is fixed downwardly with a corresponding fixed box body. The bottom of the ear plate extends through and above the bottom of the fixed box body, and the bottom of the ear plate is respectively installed with a connecting ball that rolls against the bottom of the fixed box body, and the fixed box body is filled with a number of corresponding vibration reduction damping particles. Through the intervention of the fixed box body and the rolling support connection between the ear plate itself and the bottom of the fixed box body, a stable support installation can be formed for the ear plate; and the amount of vibration directly transmitted along the ear plate to the electronic weighing device can be reduced, and most of the vibration is dispersedly transmitted along the solid box body along an extended path. During the vibration transmission process, the friction energy consumption of the vibration reduction resistance particles can form a significant vibration reduction effect, thereby significantly reducing the impact of vibration on the weighing accuracy, further improving the weighing accuracy of the present invention, and then helping to improve the crushing efficiency and crushing effect of the material.

[0029] 7) While the elastic paddle of the present invention can effectively vibrate and separate materials between the spacers when elastically plucking the spacers, this can lead to significant deformation of the spacers over time. To address this, the present invention incorporates a reinforcing rib plate at the corresponding position of the spacer through integrated molding, and embeds the support ring plate into the center of the reinforcing rib plate through an embedded mounting method. This effectively ensures the elastic paddle's ability to pry the spacers, while also effectively resolving the problem of spacer deformation caused by the elastic plucking, thereby further ensuring the practical effects of the present invention.

DETAILED DESCRIPTION

[0041] In order to facilitate understanding by those skilled in the art, the structure of the present invention is further described in detail with reference to the embodiments and the accompanying drawings:

[0042] Example 1:

[0043] refer to Figure 1-8 , a high-efficiency air flow mill equipment, comprising:

[0044] The jet mill body 1 is supported and installed by a corresponding supporting mechanism 2. The jet mill body 1 includes a sorting chamber 101 and a crushing chamber 102 connected to each other.

[0045] The crushing mechanism 3 includes a plurality of crushing nozzles 301 and a grinding disc 302 arranged at different heights on the lower side of the crushing chamber 102. Compressed air is transmitted through the crushing nozzles 301 to form a supersonic airflow to cause the material to collide and crush. A plurality of crushing pieces 303 are arranged in an upper and lower staggered manner on the periphery of the grinding disc 302. Driven by corresponding drive motors 304, the grinding disc 302 drives the crushing pieces 303 to grind and lift the material deposited at the bottom of the crushing chamber 102.

[0046] The classifying wheel 4 is disposed in the classifying chamber 101 and driven by a corresponding classifying motor 5. The classifying wheel 4 includes a fixed plate 401 connected to the output shaft end of the classifying motor 5. A plurality of corresponding spacers 402 are fixedly connected to the periphery of the fixed plate 401 in an interval state, and filter material intervals are formed between adjacent two spacers 402.

[0047] The clearing mechanism 6 includes a support ring plate 601 fixed to the inner side of the middle part of the spacer 402, and a support shaft 602 fixed to the center of the fixed plate 401. The end of the support shaft 602 is installed with a support member 603 through a one-way bearing 7. The outer end of the support member 603 can be movably abutted against the support ring plate 601. The outer end of the support member 603 is fixed with elastic paddles 604 on both sides extending between two adjacent spacers 402.

[0048] The present invention is based on the existing crushing nozzle 301, and is additionally provided with a grinding cutter disc 302. Driven by a corresponding drive motor 304, the grinding cutter disc 302 drives the crushing pieces 303 to grind and lift the materials deposited at the bottom of the crushing chamber 102 as needed.

[0049] The present invention is provided with a blockage clearing mechanism 6 on the basis of the existing grading wheel 4, which includes a support ring plate 601 fixed to the inner side of the middle part of the spacer 402, and a support shaft 602 fixed to the center of the fixed plate 401. The support ring plate 601 is used to strengthen the support of the spacer 402, and the support shaft 602 is used to cooperate with the one-way bearing 7 to realize the one-way rotation installation of the support member 603. The support of the spacer 402 can be further improved by the movable contact between the support member 603 and the support ring plate 601. Since the support member 603 is unidirectionally rotatably installed on the support shaft 60 2, therefore, when the grading motor 5 stops, when the grading wheel 4 connected to the output shaft end of the grading motor 5 quickly decelerates, the support member 603 rotatably mounted on the support shaft 602 in one direction continues to rotate quickly around the support shaft 602 under the action of inertia force, thereby forming a rotation speed difference with the grading wheel 4, so as to drive the elastic paddle 604 to pry each spacer 402 to clear the blockage, so as to realize automatic clearing of the grading wheel 4, thereby effectively preventing the grading wheel 4 from being significantly blocked, and effectively ensuring that the material that meets the particle size can be continuously and effectively output smoothly, thereby significantly improving the crushing effect and crushing efficiency of the material.

[0050] The support members 603 are arranged in a cross shape, and support balls 605 are rollingly mounted on the outer ends of the support members 603, whose outer ends abut against the support ring plate 601. The support balls 605 enable rolling engagement between the support members 603 and the support ring plate 601, thereby maintaining the support effect of the support members 603 on the support ring plate 601 and reducing friction when there is a speed difference between the two, thereby effectively ensuring the practical effects of the present invention.

[0051] The sorting chamber 101 of the jet mill body 1 is externally connected to a discharge pipe 8, and the upper portion of the pulverizing chamber 102 of the jet mill body 1 is externally connected to a feed pipe 9. A corresponding annular air bag 10 is fixedly mounted on the jet mill body 1, and is connected to an external air compressor. The pulverizing nozzle 301 is connected to the annular air bag 10 via a corresponding conducting pipe 11. A connecting ring plate 403, located within the discharge pipe 8 and spaced apart from the discharge pipe 8, is fixedly attached to the end of the spacer 402 not fixed to the fixed plate 401.

[0052] The grading motor 5 drives the grading wheel 4 to rotate, and the material that meets the particle size enters the grading wheel 4 through the gap between two adjacent spacers 402 and is output outward along the discharge pipe 8; when the grading motor 5 stops, the grading wheel 4 connected to the output shaft end of the grading motor 5 decelerates rapidly, and the support member 603 rotatably mounted on the support shaft 602 in one direction continues to rotate rapidly around the support shaft 602 under the action of inertia force, thereby forming a rotation speed difference with the grading wheel 4, so as to drive the elastic paddle 604 to pry each spacer 602 to clear the blockage.

[0053] The support mechanism 2 includes a plurality of support columns 201 evenly distributed in an annular shape around the air flow mill body 1, and the upper ends of the support columns 201 are respectively fixedly installed with corresponding electronic scales 202 upward, and the outer side walls of the air flow mill body 1 are respectively fixed outward with corresponding ear plates 203 corresponding to the support columns 201, and the ends of the ear plates 203 not connected to the air flow mill body 1 are respectively installed on the electronic scales 202, so that the air flow mill body 1 can be weighed and installed on the support columns 201; when the total weight values ​​obtained by the electronic scale 202 reaches the set value G1, the drive motor 304 is started until the total weight values ​​obtained by the electronic scale 202 are lower than the set value G2 and then turned off.

[0054] When the total weight values ​​obtained by the electronic scale 202 reaches the set value G1, it can be determined that the amount of material deposited at the bottom of the crushing chamber is relatively large. At this time, the drive motor 304 is started to drive the grinding disc 302 and the crushing piece 303 to grind and lift the material deposited at the bottom of the crushing chamber 102 until the total weight values ​​obtained by the electronic scale 202 are lower than the set value G2, and then it is closed, thereby effectively and accurately controlling the lifting process, so as to grind and lift the material deposited at the bottom of the crushing chamber as needed.

[0055] The outer side walls of the air flow mill body 1 are respectively fixed with fixing members 12 corresponding to the ear plates 203, and the outer sides of the fixing members 12 are respectively provided with corresponding embedding grooves 1201, and the ends of the ear plates 203 are respectively fixed with mounting plates 13 adapted to the embedding grooves 1201 of the fixing members 12, and the bottom side of the fixing member 12 is rotatably mounted with a corresponding driving shaft 14, and the two sides of the driving shaft 14 are respectively provided with driving threads with opposite rotation directions, and the two sides of the driving shaft 14 are respectively movably mounted with screw threads. The corresponding support guide block 15, the bottom end of the support guide block 15 can be moved to abut the bottom of the embedding groove 1201 of the fixing member 12, the upper end of the support guide block 15 is respectively set in an inward inclined shape, and the bottom end portions on both sides of the mounting plate 13 are respectively set to an inclined shape adapted to the upper end of the support guide block 15, and are provided with an inverted T-shaped slot 16 for movably engaging the support guide block 15; the driving shaft 14 is rotated to drive the support guide blocks 15 to move toward or away from each other, thereby driving the mounting plate 13 to move up or down.

[0056] In order to ensure the crushing effect and weighing accuracy of the material, the installation position of each ear plate 203 used for the installation of the air flow mill body 1 must have high accuracy requirements. Therefore, it is necessary to adjust the installation height of each ear plate 203. By rotating the drive shaft 14 of the present invention, the support guide blocks 15 can be synchronously driven to move toward or away from each other, and then the mounting plate 13 can be driven up or down to achieve convenient and high-precision adjustment of the installation height of each ear plate 203.

[0057] The fixing member 12 is provided with corresponding locking long holes, and the mounting plate 13 after the height adjustment is completed is fixed and locked on the locking long holes of the fixing member 12 by corresponding locking bolts 17 cooperating with corresponding washers.

[0058] A corresponding support sleeve 18 is rotatably mounted in the middle of each drive shaft 14. A fixed flange 19 is fixed upwardly to the bottom of each mounting groove 1201 of the fixing member 12, which is used to support the support sleeve 18. The support sleeve 18 and the fixed flange 19 ensure support for the drive shaft 14, thereby preventing excessive deformation of the drive shaft 14 and ensuring the practical effect of the present invention.

[0059] Example 2:

[0060] refer to Figure 10 The difference between this embodiment and the first embodiment is that the ear plates 203 are not connected to the ends of the air flow mill body 1 and are fixed downwardly with corresponding fixed box bodies 20, and the bottoms of the ear plates 203 extend through and extend above the bottom of the fixed box bodies 20, and the bottoms of the ear plates 203 are respectively rollingly mounted with corresponding engaging balls 21, and the bottom ends of the engaging balls 21 respectively roll and abut against the bottoms of the corresponding fixed box bodies 20, and the fixed box bodies 20 are respectively filled with a plurality of corresponding damping particles 22 for vibration reduction, and corresponding locking plates 23 are respectively provided on both sides of the fixed box bodies 20, and the locking plates 23 are fixed to the corresponding electronic scales 202 by corresponding locking bolts 24.

[0061] Because significant vibration occurs during the material pulverization process, which can adversely affect weighing accuracy, each ear plate 203 requires vibration reduction and isolation. The ends of the ear plates 203 not connected to the jet mill body 1 are each fixedly connected downwardly to a corresponding fixed housing 20. The bottoms of the ear plates 203 extend through and above the bottom of the fixed housing 20. Engaging balls 21 are rotatably mounted on the bottoms of the ear plates 203, which roll against the bottom of the fixed housing 20. The fixed housing 20 is then filled with a plurality of corresponding damping particles 22 for vibration reduction. By the intervention of the fixed box body 20 and the rolling support connection between the ear plate 203 itself and the bottom of the fixed box body 20, the ear plate 203 can be firmly supported and installed; and the amount of vibration directly transmitted along the ear plate 203 to the electronic weighing device 202 can be reduced, and most of the vibration is dispersedly transmitted along the solid box body 23 with an extended path. During the vibration transmission process, the friction energy consumption of the vibration-reducing resistance particles 22 can form a significant vibration reduction effect, thereby significantly reducing the influence of vibration on the weighing accuracy, further improving the weighing accuracy of the present invention, and then helping to improve the crushing efficiency and crushing effect of the material.

[0062] It should be noted that the implementation principle and technical effects of this embodiment are the same as those of the first embodiment. For the sake of brief description, for matters not mentioned in this embodiment, reference may be made to the corresponding content in the first embodiment.

[0063] Example 3:

[0064] refer to Figure 10 The difference between this embodiment and the first embodiment is that the spacer 402 is integrally formed with a corresponding reinforcing rib 25 at a position corresponding to the support ring plate 601, and the reinforcing rib 25 is concavely provided with a slot for embedding the support ring plate 601, and the outer end of the elastic paddle 604 is set to a shape adapted to the reinforcing rib 25 and the spacer 402.

[0065] This is because, while the elastic paddle 604 can effectively vibrate the material between the diaphragms 402 to separate them, over time, the diaphragms 402 may be significantly deformed. To address this, the present invention provides a reinforcing rib 25 at the corresponding position of the diaphragm 402 through integrated molding, and embeds the support ring plate 601 into the middle of the reinforcing rib 25 through an embedded mounting method. This effectively ensures the elastic paddle 604's elastic prying effect on the diaphragm 402 and effectively solves the problem of diaphragm 402 deformation caused by the elastic prying, thereby further effectively ensuring the practical effect of the present invention.

[0066] It should be noted that the implementation principle and technical effects of this embodiment are the same as those of the first embodiment. For the sake of brief description, for matters not mentioned in this embodiment, reference may be made to the corresponding contents in the first embodiment.

[0067] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
