Description

Technical Field

[0001] The invention relates to the technical field of air flow mills, in particular to a highly adaptable air flow mill device. 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] Existing classifying wheels for jet mills typically consist of a fixed plate connected to the output shaft of a classifying motor. Multiple spacers are spaced apart on the fixed plate. The gaps between adjacent spacers are used to classify the material. Material that meets the particle size requirements enters the classifying wheel through the gaps between adjacent spacers and is discharged through the corresponding discharge pipe. Because material easily adheres to the spacers as it flows between them, blockages often occur over extended classifying wheel operation. Consequently, the machine often needs to be disassembled to clean the classifying wheel, which is very troublesome.

[0004] Therefore, the research purpose of this invention is to design a highly adaptable air flow mill that can effectively and automatically clear the classifying wheel, thereby effectively keeping the classifying wheel from being significantly blocked for a long time, ensuring that materials that meet the particle size requirements can be continuously and effectively output smoothly, and thereby assisting in improving the crushing efficiency of the materials.

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

[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] 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.

[0014] A discharge hopper is provided at the bottom of the pulverizing chamber, and a corresponding sealing cover is detachably installed at the discharge port of the discharge hopper. Pulse nozzles staggered with the pulverizing nozzles are installed on the side walls of the discharge hopper. A corresponding annular air bag is fixedly sleeved on the main body of the jet mill, and the annular air bag is connected to an external air compressor. The pulverizing nozzle is connected to the annular air bag through a corresponding first conducting pipe, and the pulse nozzle is connected to the annular air bag through a corresponding pulse valve and a second conducting pipe.

[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 pulse valve opens until the total weight values obtained by the electronic scales are lower than the set value G2 and then closes.

[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] A corresponding arc-shaped top cover is provided on the top of the sorting chamber, and the arc-shaped top cover is configured as an arc structure with the center of the discharge pipe as the center of the circle.

[0020] 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.

[0021] Advantages of the present invention:

[0022] 1) The present invention is provided with a blockage clearing mechanism on the basis of the grading wheel, which includes a supporting ring plate fixedly connected to the inner side of the middle part of the spacer and a supporting shaft fixedly connected to the center of the fixed plate. The support of the spacer is strengthened by the intervention of the supporting ring plate, and the intervention of the supporting shaft can 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 supporting ring plate. Since the support member is mounted on the support shaft in a one-way rotation manner, when the grading motor stops, when the grading wheel connected to the output shaft end of the grading motor quickly decelerates, the support member rotatably mounted on the support shaft in a one-way manner continues to rotate rapidly around the support shaft under the action of inertia force, thereby forming a rotation speed difference with the grading wheel, so as to drive the elastic paddle to pry each spacer to clear the blockage.

[0023] Therefore, the classifying wheel can be automatically cleared while improving its structural stability, so as to effectively prevent the classifying wheel from being blocked for a long time, thereby ensuring that materials that meet the particle size requirements can be continuously and effectively discharged, thereby helping to improve the material 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) During the jet mill pulverization process, some material will inevitably bypass the pulverizing nozzles and accumulate at the bottom of the pulverizing chamber, thereby affecting the pulverizing process of the present invention. To this end, the present invention provides a discharge hopper at the bottom of the pulverizing chamber. Pulse nozzles are mounted on the sidewalls of the discharge hopper, interlaced with the pulverizing nozzles. Furthermore, corresponding electronic scales are fixedly mounted upwardly on the upper ends of the support columns of the present invention. The outer sidewalls of the jet mill body are fixedly connected to the support columns, extending outwardly from the corresponding lugs. The ends of the lugs not connected to the jet mill body are mounted on the corresponding electronic scales.

[0026] The material deposited downward is collected through the discharge hopper, and the air flow mill body is then mounted on the support column with a weighable structure. When the total weight values obtained by the electronic scale reaches the set value G1, it can be determined that the amount of material deposited in the discharge hopper is relatively large. At this time, the pulse valve opens, and high-pressure gas passes through the pulse nozzle to lift the deposited material, allowing the deposited material to re-enter the crushing operation until the total weight values obtained by the electronic scale are lower than the set value G2 and then the valve is closed, thereby effectively improving the crushing efficiency and crushing effect of the material.

[0027] 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.

[0028] 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.

[0029] 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.

DETAILED DESCRIPTION

[0041] To facilitate understanding by those skilled in the art, the structure of the present invention will now be described in further detail with reference to the accompanying drawings.

[0042] Example 1:

[0043] refer to Figure 1-8 , a highly adaptable air jet mill device, 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 from top to bottom. The sorting chamber 101 is externally connected to a discharge pipe 3, and the upper part of the crushing chamber 102 is externally connected to a feed pipe 4;

[0045] The crushing mechanism 5 comprises a plurality of crushing nozzles 501 evenly distributed on the lower side of the crushing chamber 102. Compressed air is transmitted through the crushing nozzles 501 to form a supersonic airflow to cause the material to collide and crush.

[0046] A classifying wheel 6 is disposed in the sorting chamber 101. One end of the classifying wheel 6 is transmission-connected to the output shaft end of the corresponding classifying motor 7. The classifying wheel 6 includes a fixed plate 601 transmission-connected to the output shaft end of the classifying motor 7. A plurality of corresponding spacers 602 are fixedly connected to the periphery of the fixed plate 601 in an interval state. Filter material intervals are formed between two adjacent spacers 602.

[0047] The clearing mechanism 8 comprises a support ring plate 801 fixed to the inner side of the middle of the spacer 602, and a support shaft 802 fixed to the center of the fixed plate 601. The end of the support shaft 802 is mounted with a support member 803 through a one-way bearing 9. The outer end of the support member 803 can be movably abutted against the support ring plate 801, and the outer end of the support member 803 is fixed with elastic paddles 804 extending between two adjacent spacers 602 on both sides; the grading motor 7 drives the grading wheel 6 rotates, and materials that meet the particle size enter the grading wheel 6 through the gap between two adjacent spacers 602 and are output outward along the discharge pipe 3; when the grading motor 7 stops, the grading wheel 6 connected to the output shaft end of the grading motor 7 decelerates rapidly, and the support member 803 rotatably mounted on the support shaft 802 in one direction continues to rotate rapidly around the support shaft 802 under the action of inertia force, thereby forming a rotation speed difference with the grading wheel 6, so as to drive the elastic paddle 804 to pry each spacer 602 to clear the blockage.

[0048] The present invention is provided with a blockage clearing mechanism 8 on the basis of the grading wheel 6, which includes a support ring plate 801 fixedly connected to the inner side of the middle part of the spacer 602, and a support shaft 802 fixedly connected to the center of the fixed plate 601. The support ring plate 801 is used to strengthen the support of the spacer 602, and the support shaft 802 is used to cooperate with the one-way bearing 9 to realize the unidirectional rotation installation of the support member 803. The support of the spacer 602 can be further improved by the movable abutment between the support member 803 and the support ring plate 801. Since the support member 803 is unidirectionally rotatably mounted on the support shaft 802, when the grading motor 7 stops, when the grading wheel 6 connected to the output shaft end of the grading motor 7 decelerates rapidly, the support member 803 unidirectionally rotatably mounted on the support shaft 802 continues to rotate rapidly around the support shaft 802 under the action of inertia, thereby forming a rotation speed difference with the grading wheel 6, so as to drive the elastic paddle 804 to pry each spacer to clear the blockage. Therefore, the classifying wheel 6 can be automatically cleared while the structural stability of the classifying wheel 6 is effectively improved, so as to effectively keep the classifying wheel 6 from being significantly blocked for a long time, thereby ensuring that the material that meets the particle size can be continuously and effectively output smoothly, thereby helping to improve the material crushing efficiency.

[0049] The support members 803 are arranged in a cross shape, and support balls 805 are rotatably mounted on the outer ends of the support members 803, and the outer ends of the support members 803 abut against the support ring plate 801. The end of the spacer 602 not fixed to the fixed plate 601 is fixed to a connecting ring plate 603 located inside the discharge pipe 3 and disposed with a gap therebetween.

[0050] By intervening with the support ball 805, a rolling connection is achieved between the support member 803 and the support ring plate 801, which can not only maintain the supporting effect of the support member 803 on the support ring plate 801, 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.

[0051] A discharge hopper 10 is provided at the bottom of the pulverizing chamber 102, and a corresponding sealing cover 11 is detachably installed at the discharge port of the discharge hopper 10. Pulse nozzles 502 staggered with the pulverizing nozzles 501 are installed on the side walls of the discharge hopper 10. A corresponding annular air bag 503 is fixedly sleeved on the jet mill body 1, and the annular air bag 503 is connected to an external air compressor. The pulverizing nozzle 501 is connected to the annular air bag 503 through a corresponding first conducting pipe 12, and the pulse nozzle 502 is connected to the annular air bag 503 through a corresponding pulse valve 13 and a second conducting pipe 14.

[0052] 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 pulse valve 13 opens until the total weight values obtained by the electronic scale 202 is lower than the set value G2 and then closes.

[0053] During the pulverizing process of the jet mill, some material will inevitably bypass the location of the pulverizing nozzle 501 and accumulate at the bottom end of the pulverizing chamber 102, thereby affecting the pulverizing process of the present invention. To this end, the present invention provides a discharge hopper 10 at the bottom of the pulverizing chamber 102, and the side walls of the discharge hopper 10 are mounted with pulse nozzles 502 arranged in an alternating manner with the pulverizing nozzles 501. In addition, the upper ends of the support columns 201 of the present invention are respectively fixedly mounted with corresponding electronic scales 202 upwardly. The outer side walls of the jet mill body 1 are respectively fixedly connected to the support columns 201 with corresponding ear plates 203 extending outwardly. The ends of the ear plates 203 not connected to the jet mill body 1 are respectively mounted on the corresponding electronic scales 202. The material deposited downward is collected through the discharge hopper 10, and the air flow mill body 1 is mounted on the support column in a weighable manner. 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 in the discharge hopper 10 is relatively large. At this time, the pulse valve 13 is opened, and high-pressure gas passes through the pulse nozzle 502 to lift the deposited material, so that the deposited material re-enters the crushing operation until the total weight values obtained by the electronic scale 202 are lower than the set value G2 and then closed, thereby effectively improving the crushing efficiency and crushing effect of the material.

[0054] The outer wall of the air flow mill body 1 is respectively fixed with a fixing member 15 corresponding to the ear plate 203, and the outer side of the fixing member 15 is respectively provided with a corresponding embedding groove 1501, and the end of the ear plate 203 is respectively fixed with a mounting plate 16 adapted to the embedding groove 1501 of the fixing member 15. The bottom side of the fixing member 15 is rotatably mounted with a corresponding drive shaft 17, and the two sides of the drive shaft 17 are respectively provided with drive threads with opposite rotation directions, and the two sides of the drive shaft 17 are respectively movably mounted by threaded connection. There are corresponding support guide blocks 18, the bottom ends of the support guide blocks 18 can be moved to abut the bottom of the embedding groove of the fixing member 15, and the upper ends of the support guide blocks 18 are respectively arranged in an inward inclined shape. The bottom ends on both sides of the mounting plate 16 are respectively arranged in an inclined shape adapted to the upper end of the support guide blocks 18, and are provided with inverted T-shaped slots 1601 for movably engaging the support guide blocks 18; the driving shaft 17 is rotated to drive the support guide blocks 18 to move toward or away from each other, thereby driving the mounting plate 16 to move up or down.

[0055] The fixing member 15 is provided with corresponding locking long holes, and the mounting plate 16 after the height adjustment is completed is fixed and locked on the locking long holes of the fixing member 15 by corresponding locking bolts 19 cooperating with corresponding washers.

[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 17 of the present invention, the support guide blocks 18 can be synchronously driven to move toward or away from each other, and then the mounting plate 16 can be driven up or down to achieve convenient and high-precision adjustment of the installation height of each ear plate 203.

[0057] A corresponding support sleeve 20 is rotatably mounted in the middle of each drive shaft 17. A fixed flange 21 is fixed upwardly to the bottom of each mounting groove 1501 of the fixing member 15, providing support for each support sleeve 20. The support sleeve 20 and the fixed flange 21 ensure support for the drive shaft 17, thereby preventing excessive deformation of the drive shaft 17 and maintaining the practical effect of the present invention.

[0058] A corresponding arc-shaped top cover 22 is provided on the top of the sorting chamber 101 . The arc-shaped top cover 22 is configured as an arc structure with the center of the discharge pipe 3 as the center.

[0059] Example 2:

[0060] refer to Figure 9The 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 23, and the bottoms of the ear plates 203 extend through and above the bottom of the fixed box bodies 23, and the bottoms of the ear plates 203 are respectively rollingly installed with corresponding engaging balls 24, and the bottom ends of the engaging balls 24 respectively roll and abut against the bottoms of the corresponding fixed box bodies 23, and the fixed box bodies 23 are respectively filled with a plurality of corresponding damping particles 25 for vibration reduction, and corresponding locking plates 26 are respectively provided on both sides of the fixed box bodies 23, and the locking plates 26 are fixed to the corresponding electronic scales 202 by corresponding locking bolts 27.

[0061] Because significant vibration occurs during the material pulverization process, which can adversely affect weighing accuracy, each lug plate 203 requires vibration reduction and isolation. The ends of the lug plates 203 not connected to the jet mill body 1 are each fixedly connected downwardly to a corresponding fixed housing 23. The bottoms of the lug plates 203 extend through and above the bottom of the fixed housing 23. Engaging balls 24 are rotatably mounted on the bottoms of the lug plates 203, which roll against the bottom of the fixed housing 23. The fixed housing 23 is filled with a plurality of corresponding damping particles 25 for vibration reduction. By the intervention of the fixed box body 23 and the rolling support connection between the ear plate 203 itself and the bottom of the fixed box body 23, 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 25 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 602 is integrally formed with a corresponding reinforcing rib 28 at a position corresponding to the elastic pick 804, and the reinforcing rib 28 is concavely provided with a slot for embedding the support ring plate 801, and the outer end of the elastic pick 804 is set to a shape adapted to the reinforcing rib 28 and the spacer 602.

[0065] This is because, when the elastic pick 804 elastically moves the spacer 602, although it can effectively separate the material between the spacers 602 through vibration, as the use time increases, the spacer 602 may be significantly deformed. For this reason, the present invention provides a reinforcing rib plate 28 at the corresponding position of the spacer 602 through an integrated molding method, and embeds the support ring plate 801 into the middle of the reinforcing rib plate 28 through an embedded method. In this way, it can effectively ensure the elastic moving effect of the elastic pick 804 on the spacer 602, and can effectively solve the deformation problem of the spacer 602 caused by the elastic moving, thereby effectively further 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.
