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 pulverizing chamber as needed, and can effectively solve the problem of material blockage of a grading wheel, thereby significantly improving the pulverizing effect and pulverizing efficiency of the material. Background Art

[0002] Airflow mill is a processing method that uses high-speed airflow to grind the surface of materials. It uses the high-speed rotating flow field generated by the airflow to make the materials rotate, collide and rub continuously in the airflow, thereby achieving the purpose of grinding and crushing the materials. The upper part of the existing airflow mill is equipped with a corresponding classification wheel, which is driven by a classification motor to rotate. The materials that meet the particle size requirements are classified by the classification wheel and then discharged along the corresponding discharge pipe. The materials that do not meet the particle size requirements are returned to the grinding chamber of the airflow mill for re-crushing.

[0003] The existing classifying wheel for air flow mill generally includes a fixed plate connected to the output shaft end of the classifying motor, and a plurality of spacers are arranged on the fixed plate in an interval state. The materials are classified through the gap between two adjacent spacers. The materials that meet the particle size enter the classifying wheel through the gap between the two adjacent spacers and are discharged along the corresponding discharge pipe. Since the materials are easy to adhere 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; and since some materials with larger particles are easy to form deposits 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 the materials to lift the deposited materials upwards, so that they re-enter the high-pressure airflow for re-crushing. However, the lifting process will significantly increase the concentration of the materials in a short 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 and effectively clear the classifying wheel, thereby effectively preventing obvious blockage of the classifying wheel, ensuring that 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.

[0012] The fixing members are respectively provided with corresponding locking long holes, and the mounting plate after the height adjustment is fixed and locked on the locking long holes of the fixing members through the cooperation of corresponding locking bolts and corresponding gaskets.

[0013] The middle part of the driving shaft is rotatably mounted with a corresponding supporting sleeve, and the bottom of the mounting groove of the fixing member is upwardly fixedly connected with a fixing convex edge for supporting the supporting sleeve.

[0016] Advantages of the present invention: 1) The present invention is provided with a grinding cutter disc on the basis of the existing pulverizing nozzle. Driven by a corresponding driving 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; The present invention is provided with a clearing mechanism on the basis of the existing 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, and 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 supporting shaft in a one-way rotational manner, when the grading motor stops, when the grading wheel connected to the output shaft end of the grading motor decelerates rapidly, the support member unidirectionally rotatably mounted on the supporting shaft continues to rotate rapidly around the supporting 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 and clear the blockage of each spacer, so as to realize automatic clearing of the grading wheel, thereby effectively preventing the grading wheel from being significantly blocked, so as to effectively ensure that the material meeting the particle size can be continuously and effectively output smoothly, thereby significantly improving the crushing effect and crushing efficiency of the material.

[0017] 2) The support members of the present invention 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. 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.

[0018] 3) The upper ends of the support columns of the present invention are respectively fixedly mounted with corresponding electronic weighing devices, and the outer side walls of the jet mill body are respectively fixedly connected with corresponding ear plates corresponding to the support columns, and the ends of the ear plates not connected to the jet mill body are respectively mounted on the electronic weighing devices. When the total weight values ​​obtained by the electronic weighing device reach the set value G 1 When the amount of material deposited at the bottom of the crushing chamber is relatively large, the drive motor starts to drive the grinding cutter and the crushing sheet to grind and lift the material deposited at the bottom of the crushing chamber until the total weight value obtained by the electronic weighing device is lower than the set value G. 2 Then close it, so as to effectively and accurately control the material raising process, so as to grind and raise the materials deposited at the bottom of the crushing chamber as needed.

[0019] 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, the outer sides of the fixing parts are respectively provided with corresponding embedding grooves, the ends of the ear plates are respectively fixed with mounting plates adapted to the embedding grooves of the fixing parts, a driving shaft is rotatably mounted on the bottom side of the fixing parts, 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 connection, the upper ends of the support guide blocks are respectively provided inwardly inclined, the bottom ends of the two sides of the mounting plate are respectively provided in inclined shapes adapted to the upper ends of the support guide blocks, and inverted T-shaped slots for movably engaging the support guide blocks are provided. In order to ensure the crushing effect and weighing accuracy of the material, the installation position of each ear plate used for installing the air flow mill body has 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.

[0020] 5) The drive shaft of the present invention is rotatably mounted with a corresponding support sleeve in the middle, and the bottom of the mounting groove of the fixing member is fixedly connected upward with a fixed convex edge for supporting the support sleeve. The support sleeve and the fixed convex edge are used to ensure the support of the drive shaft, thereby preventing the drive shaft from excessive deformation and ensuring the practical effect of the present invention.

[0021] 6) Since there is a significant amount of vibration during the material crushing process, it will have an adverse effect 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 airflow mill body and is fixed downward with a corresponding fixed box body. The bottom of the ear plate extends through and extends to the top of 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 damping particles for vibration reduction. 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, the ear plate can be stably supported and installed; 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 with 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, so as to further improve the weighing accuracy of the present invention, and then assist in improving the crushing efficiency and crushing effect of the material.

[0022] 7) When the elastic paddle of the present invention elastically pokes the diaphragm, although it can effectively make the material between the diaphragms separate from the diaphragms by means of vibration, the diaphragm may be significantly deformed as the use time increases. To this end, the present invention provides a reinforcing rib plate at the corresponding position of the diaphragm by means of integrated molding, and embeds the supporting ring plate into the middle of the reinforcing rib plate by means of embedding. In this way, the elastic paddle can effectively ensure the elastic poke effect on the diaphragm, and can effectively solve the problem of diaphragm deformation caused by the elastic poke, thereby effectively further ensuring the practical effect of the present invention.

DETAILED DESCRIPTION

[0034] 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 in conjunction with the accompanying drawings: Embodiment 1: refer to Figure 1-8 , a high-efficiency jet mill equipment, comprising: The jet mill body 1 is supported and installed by a corresponding supporting mechanism 2, and the jet mill body 1 comprises a sorting chamber 101 and a crushing chamber 102 which are connected up and down; The crushing mechanism 3 comprises a plurality of crushing nozzles 301 and a grinding disc 302 arranged at different heights at the lower side of the crushing chamber 102. The crushing nozzles 301 transmit compressed air to form a supersonic airflow to cause the material to collide and crush. A plurality of crushing pieces 303 are arranged alternately up and down at the periphery of the grinding disc 302. Under the drive of a corresponding driving motor 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. The classifying wheel 4 is arranged in the classifying chamber 101 and driven by the corresponding classifying motor 5. The classifying wheel 4 comprises a fixing 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 fixing plate 401 in an interval state, and a filter material interval is formed between two adjacent spacers 402. The clearing mechanism 6 includes a support ring plate 601 fixedly connected to the inner side of the middle part of the spacer 402, and a support shaft 602 fixedly connected to the center of the fixed plate 401. The end of the support shaft 602 is equipped 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 extending on both sides to between two adjacent spacers 402.

[0035] The present invention is provided with a grinding cutter disc 302 on the basis of the existing crushing nozzle 301. Driven by the corresponding driving 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 required. In addition, the present invention is provided with a clearing mechanism 6 on the basis of the existing grading wheel 4, which includes a support ring plate 601 fixedly connected to the inner side of the middle of the spacer 402, and a support shaft 602 fixedly connected 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 decelerates rapidly, the support member 603 rotatably mounted on the support shaft 602 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 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, so as to effectively ensure that the materials meeting the particle size can be continuously and effectively output smoothly, thereby significantly improving the crushing effect and crushing efficiency of the materials.

[0036] The support member 603 is arranged in a cross shape, and the outer ends of the support member 603 are respectively rollingly mounted with support balls 605 whose outer ends abut against the support ring plate 601. Through the intervention of the support balls 605, the rolling connection between the support member 603 and the support ring plate 601 is achieved, which can not only maintain the supporting effect of the support member 603 on the support ring plate 601, 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.

[0037] The sorting chamber 101 of the jet mill body 1 is connected to the discharge pipe 8, and the upper part of the crushing chamber 102 of the jet mill body 1 is connected to the feed pipe 9; a corresponding annular air bag 10 is fixedly sleeved on the jet mill body 1, and the annular air bag 10 is connected to the external air compressor, and the crushing nozzle 301 is connected to the annular air bag 10 through a corresponding conducting pipe 11. The end of the spacer 402 that is not fixed to the fixed plate 401 is fixedly connected to a connecting ring plate 403 located in the discharge pipe 8 and arranged with a gap between the discharge pipe 8 and the discharge pipe 8.

[0038] 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 3; 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 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 and clear each spacer 602.

[0039] The support mechanism 2 comprises a plurality of support columns 201 evenly distributed in an annular shape around the airflow mill body 1, and the upper ends of the support columns 201 are respectively fixedly mounted with corresponding electronic weighing devices 202 upwardly, and the outer side walls of the airflow mill body 1 are respectively fixedly connected with corresponding ear plates 203 outwardly corresponding to the support columns 201, and the ends of the ear plates 203 not connected to the airflow mill body 1 are respectively correspondingly mounted on the electronic weighing devices 202, so that the airflow mill body 1 can be weighed and mounted on the support columns 201; when the total weight values ​​obtained by the electronic weighing devices 202 reach the set value G 1 When the driving motor 304 is started, the total weight value obtained by the electronic weighing device 202 is lower than the set value G 2 Then close.

[0040] When the total weight value obtained by the electronic weighing device 202 reaches the set value G 1 When the amount of material deposited at the bottom of the crushing chamber is relatively large, the driving motor 304 is started to drive the grinding blade 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 value obtained by the electronic weighing device 202 is lower than the set value G. 2 Then close it, so as to effectively and accurately control the material raising process, so as to grind and raise the materials deposited at the bottom of the crushing chamber as needed.

[0041] The outer wall of the airflow mill body 1 is respectively fixed with a fixing member 12 corresponding to the ear plate 203, and the outer side of the fixing member 12 is respectively provided with a corresponding embedding groove 1201, and the end of the ear plate 203 is respectively fixed with a mounting plate 13 adapted to the embedding groove 1201 of the fixing member 12, and a corresponding driving shaft member 14 is rotatably installed on the bottom side of the fixing member 12, and driving threads with opposite rotation directions are respectively provided on both sides of the driving shaft member 14, and the two sides of the driving shaft member 14 are respectively movably installed with a screw thread. Corresponding support guide blocks 15, the bottom ends of the support guide blocks 15 can be moved to abut against the bottom of the mounting groove 1201 of the fixing member 12, the upper ends of the support guide blocks 15 are respectively arranged in an inward inclined shape, and the bottom ends on both sides of the mounting plate 13 are respectively arranged in an inclined shape adapted to the upper ends of the support guide blocks 15, and are provided with inverted T-shaped slots 16 for movably engaging the support guide blocks 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.

[0042] In order to ensure the crushing effect and weighing accuracy of the material, the installation position of each ear plate 203 used for installing the air flow mill body 1 has 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 to move up or down, so as to achieve convenient and high-precision adjustment of the installation height of each ear plate 203.

[0043] The fixing member 12 is provided with corresponding long locking holes, and the mounting plate 13 after height adjustment is fixed and locked on the long locking holes of the fixing member 12 by means of corresponding locking bolts 17 cooperating with corresponding gaskets.

[0044] The middle of the driving shaft 14 is rotatably mounted with a corresponding supporting sleeve 18, and the bottom of the mounting groove 1201 of the fixing member 12 is respectively fixedly connected upward with a fixing convex edge 19 for supporting the supporting sleeve 18. The support of the driving shaft 14 is ensured by the intervention of the supporting sleeve 18 and the fixing convex edge 19, thereby preventing the driving shaft 14 from excessive deformation, thereby ensuring the practical effect of the present invention.

[0045] Embodiment 2: refer to Fig.10The difference between this embodiment and the first embodiment is that the ear plate 203 is not connected to the end of the air flow mill body 1 and is fixed downward with a corresponding fixed box body 20, and the bottom of the ear plate 203 extends through and extends above the bottom of the fixed box body 20, and the bottom of the ear plate 203 is rollingly installed with a corresponding connecting ball 21, and the bottom end of the connecting ball 21 rolls and abuts against the bottom of the corresponding fixed box body 20, and the fixed box body 20 is filled with a plurality of corresponding damping particles 22 for vibration reduction, and corresponding locking plates 23 are respectively arranged on both sides of the fixed box body 20, and the locking plates 23 are fixed to the corresponding electronic weighing device 202 by corresponding locking bolts 24.

[0046] Since there is a significant amount of vibration during the material crushing process, it will have an adverse effect on the weighing accuracy. Therefore, it is necessary to perform vibration reduction and vibration isolation treatment on each ear plate 203. The ear plate 203 of the present invention is not connected to the end of the airflow mill body 1 and is fixed downwardly with a corresponding fixed box body 20. The bottom of the ear plate 203 extends through and extends above the bottom of the fixed box body 20. The bottom of the ear plate 203 is respectively installed with a connecting ball 21 that rolls against the bottom of the fixed box body 20, and the fixed box body 20 is respectively filled with a plurality of corresponding damping particles 22 for vibration reduction. Through 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 stably supported and installed; and the amount of vibration directly transmitted along the ear plate 203 to the electronic weighing device 202 can be reduced, while 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 an obvious vibration reduction effect, thereby significantly reducing the influence of vibration on the weighing accuracy, so as to further improve the weighing accuracy of the present invention, and then assist in improving the crushing efficiency and crushing effect of the material.

[0047] It should be pointed out that the implementation principle and technical effects of this embodiment are the same as those of Embodiment 1. For the sake of brief description, for matters not mentioned in this embodiment, reference may be made to the corresponding contents in Embodiment 1.

[0048] Embodiment three: refer to Fig.10 The difference between this embodiment and the first embodiment is that: the spacer 402 is integrally formed with a corresponding reinforcing rib plate 25 at a position corresponding to the supporting ring plate 601, and the reinforcing rib plate 25 is concavely provided with a slot for embedding the supporting ring plate 601, and the outer end of the elastic paddle 604 is set to a shape adapted to the reinforcing rib plate 25 and the spacer 402.

[0049] This is because, when the elastic paddle 604 elastically pokes the diaphragm 402, although it can effectively make the material between the diaphragms 402 separate from the diaphragms 402 by means of vibration, as the use time increases, the diaphragm 402 may be significantly deformed. To this end, the present invention provides a reinforcing rib plate 25 at the corresponding position of the diaphragm 402 by means of integrated molding, and embeds the support ring plate 601 into the middle of the reinforcing rib plate 25 by means of embedding, so that the elastic paddle 604 can effectively ensure the elastic poke effect on the diaphragm 402, and can effectively solve the problem of deformation of the diaphragm 402 caused by the elastic poke, thereby effectively further ensuring the practical effect of the present invention.

[0050] It should be pointed out that the implementation principle and technical effects of this embodiment are the same as those of Embodiment 1. For the sake of brief description, for matters not mentioned in this embodiment, reference may be made to the corresponding contents in Embodiment 1.

[0051] 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 principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
