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] 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 jet 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 two adjacent spacers and are discharged along the corresponding discharge pipe. Since the materials are easily attached to the spacers when flowing between two adjacent spacers, the problem of material blockage often occurs as the running time of the classifying wheel increases. Therefore, it is often necessary to dismantle the machine to clean the classifying wheel, which is very troublesome.

[0004] Therefore, the purpose of the present invention is to design a highly adaptable air flow mill that can automatically and effectively 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.

[0018] 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.

[0019] 3) During the pulverizing process of the airflow mill, some materials will inevitably bypass the location of the pulverizing nozzle and accumulate at the bottom end of the pulverizing chamber, thereby affecting the pulverizing process of the present invention. To this end, a discharge hopper is provided at the bottom of the pulverizing chamber of the present invention, and a pulse nozzle staggered with the pulverizing nozzle is installed on the side wall of the discharge hopper, and the upper end of the support column of the present invention is respectively fixedly installed with a corresponding electronic weighing device upward, and the outer side wall of the airflow mill body is respectively fixedly connected to the outside with a corresponding ear plate corresponding to the support column, and the end of the ear plate not connected to the airflow mill body is respectively installed on the electronic weighing device.

[0020] The material deposited downward is collected through the discharge hopper, and the jet mill body is weighed and installed on the support column. When the total weight value obtained by the electronic weighing device reaches the set value G 1 When the pulse valve opens, the high-pressure gas passes through the pulse nozzle to lift the deposited material, so that the deposited material re-enters the crushing operation until the total weight value obtained by the electronic weighing device is lower than the set value G. 2 Then just close it, so as to effectively improve the crushing efficiency and crushing effect of the materials.

[0021] 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.

[0022] 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.

[0023] 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.

DETAILED DESCRIPTION

[0035] 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 highly adaptable jet mill device, comprising: The jet mill body 1 is supported and installed by a corresponding supporting mechanism 2.

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; The crushing mechanism 5 comprises a plurality of crushing nozzles 501 evenly arranged at the lower side of the crushing chamber 102, and compressed air is transmitted through the crushing nozzles 501 to form a supersonic airflow to cause the material to collide and crush; A classifying wheel 6 is arranged 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 comprises a fixing plate 601 which is transmission-connected to the output shaft end of the classifying motor 7, a plurality of corresponding spacers 602 are fixedly connected at the periphery of the fixing plate 601 in an interval state, and a filter material interval is formed between two adjacent spacers 602; 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 installed 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 meeting the particle size enter the grading wheel 6 through the interval 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.

[0036] The present invention is provided with a 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 intervened to strengthen the support of the spacer 602, and the support shaft 802 is intervened to cooperate with the one-way bearing 9 to realize the one-way 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 installed 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 installed on the support shaft 802 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 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 obviously blocked for a long time, thereby ensuring that the materials meeting the particle size can be continuously and effectively output smoothly, so as to help improve the crushing efficiency of the materials.

[0037] The support member 803 is arranged in a cross shape, and the outer ends of the support member 803 are respectively rollingly mounted with support balls 805 whose outer ends abut against the support ring plate 801. The end of the spacer 602 not fixed to the fixed plate 601 is fixedly connected to a connecting ring plate 603 located in the discharge pipe 3 and arranged with a gap therebetween.

[0038] By introducing the support ball 805, the rolling connection between the support member 803 and the support ring plate 801 is achieved, which can not only maintain the support 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.

[0039] 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 air flow 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.

[0040] 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 pulse valve 13 is opened, the total weight value obtained by the electronic weighing device 202 is lower than the set value G 2 Then close.

[0041] During the pulverizing process of the air flow mill, it is inevitable that some materials will 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, a discharge hopper 10 is provided at the bottom of the pulverizing chamber 102 of the present invention, and pulse nozzles 502 staggered with the pulverizing nozzles 501 are installed on the side walls of the discharge hopper 10, and corresponding electronic weighing devices 202 are fixedly installed upward on the upper ends of the support columns 201 of the present invention, and corresponding ear plates 203 are fixedly connected to the outside of the outer side walls of the air flow mill body 1 corresponding to the support columns 201, and the ends of the ear plates 203 not connected to the air flow mill body 1 are correspondingly installed on the electronic weighing devices 202. The material deposited downward is collected through the discharge hopper 10, and then the air flow mill body 1 can be weighed and installed on the support column. When the total weight value obtained by the electronic weighing device 202 reaches the set value G 1 When the amount of material deposited in the discharge hopper 10 is relatively large, the pulse valve 13 is opened, and the 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 value obtained by the electronic weighing device 202 is lower than the set value G. 2 Then just close it, so as to effectively improve the crushing efficiency and crushing effect of the materials.

[0042] The outer wall of the airflow 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, and a corresponding driving shaft member 17 is rotatably installed on the bottom side of the fixing member 15, and the two sides of the driving shaft member 17 are respectively provided with driving threads with opposite rotation directions, and the two sides of the driving shaft member 17 are respectively movably installed by threaded connection. There are corresponding support guide blocks 18, the bottom ends of the support guide blocks 18 can be movably abutted against the bottom of the embedding groove of the fixing member 15, the upper ends of the support guide blocks 18 are respectively arranged in an inward inclined shape, and the bottom ends on both sides of the mounting plate 16 are respectively arranged in an inclined shape adapted to the upper ends 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.

[0043] The fixing member 15 is provided with corresponding long locking holes, and the mounting plate 16 after height adjustment is fixed and locked on the long locking holes of the fixing member 15 by means of corresponding locking bolts 19 cooperating with corresponding gaskets.

[0044] 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 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 to move up or down, so as to achieve convenient and high-precision adjustment of the installation height of each ear plate 203.

[0045] The middle of the driving shaft 17 is rotatably mounted with a corresponding supporting sleeve 20, and the bottom of the mounting groove 1501 of the fixing member 15 is respectively fixedly connected upward with a fixing convex edge 21 for supporting the supporting sleeve 20. The support of the driving shaft 17 is ensured by the intervention of the supporting sleeve 20 and the fixing convex edge 21, thereby preventing the driving shaft 17 from excessive deformation, thereby ensuring the practical effect of the present invention.

[0046] A corresponding arc-shaped top cover 22 is disposed on the top of the sorting chamber 101 , and the arc-shaped top cover 22 is configured as an arc structure with the center of the discharge pipe 3 as the center of the circle.

[0047] Embodiment 2: refer to Fig. 9The difference between this embodiment and the first embodiment is that the ear plate 203 that is not connected to the end of the air flow mill body 1 is fixed downward with a corresponding fixed box body 23, and the bottom of the ear plate 203 extends through and extends to the top of the bottom of the fixed box body 23, and the bottom of the ear plate 203 is rollingly installed with corresponding connecting balls 24, and the bottom ends of the connecting balls 24 roll and abut against the bottom of the corresponding fixed box body 23, and the fixed box body 23 is filled with a plurality of corresponding damping particles 25 for vibration reduction, and corresponding locking plates 26 are respectively arranged on both sides of the fixed box body 23, and the locking plates 26 are fixed to the corresponding electronic weighing device 202 by corresponding locking bolts 27.

[0048] 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 downward with a corresponding fixed box body 23. The bottom of the ear plate 203 extends through and extends above the bottom of the fixed box body 23. The bottom of the ear plate 203 is respectively installed with a connecting ball 24 that rolls against the bottom of the fixed box body 23, and the fixed box body 23 is respectively 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 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 25 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 help improve the crushing efficiency and crushing effect of the material.

[0049] 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.

[0050] Embodiment three: refer to Fig.10 The difference between this embodiment and the first embodiment is that: the spacer 602 is integrally formed with a corresponding reinforcing rib plate 28 at a position corresponding to the elastic pick 804, and the reinforcing rib plate 28 is concavely provided with a groove for embedding the supporting ring plate 801, and the outer end of the elastic pick 804 is set to a shape adapted to the reinforcing rib plate 28 and the spacer 602.

[0051] This is because, when the elastic paddle 804 elastically pokes the diaphragm 602, although it can effectively separate the material between the diaphragms 602 through vibration, as the use time increases, the diaphragm 602 may be significantly deformed. For this reason, the present invention provides a reinforcing rib plate 28 at the corresponding position of the diaphragm 602 through an integrated molding method, and embeds the support ring plate 801 into the middle part of the reinforcing rib plate 28 through an embedded method. In this way, the elastic paddle 804 can effectively ensure the elastic plucking effect on the diaphragm 602, and can effectively solve the deformation problem of the diaphragm 602 caused by the elastic plucking, thereby effectively further ensuring the practical effect of the present invention.

[0052] 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.

[0053] 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.
