[0002] Wet grinding is an efficient crushing and mixing process, which is widely used in the fields of ceramic powders, nanomaterials, etc. The characteristic of wet grinding is that the particle size is finer. When the sample is ground to a fine state, it is affected by the intermolecular force and agglomerated. However, the grinding aid can break this force and grind the sample to a finer state. Water as a grinding aid can reduce the phenomenon of material sticking to ball stones and the inner wall of the cylinder, increase the movement speed of the ball mill, shorten the ball milling time of the material, and improve production efficiency.

[0003] In combination with the above, it is necessary to explain that the wet grinding discharge is usually discharged together with the grinding aid, but in the prior art, the powder with the grinding aid is often transported by pipeline after the discharge.

DETAILED DESCRIPTION

[0028] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Embodiment 1: In order to solve the problem that the particle size of the discharge material and the quality of the ground product are limited due to the inability to accurately control the operating parameters, the following technical solution is proposed:

[0030] Reference Figure 1 - Figure 8 As shown, the adaptive discharging structure based on the wet grinding process in this embodiment includes a discharging box 1, a control panel is arranged on the discharging box 1, a feeding pipe 2 and a discharging pipe 3 are respectively arranged horizontally and staggered at both ends of the discharging box 1, an inner drum 5 is rotatably installed in the middle of the discharging box 1 through a rotating ring 18, and a rotary filter assembly 4 is rotatably arranged in an annular array inside the inner drum 5;

[0031] The rotary filter assembly 4 includes a coaxially arranged rotor 1 8 and a rotor 2 15, a synchronization rod 44 is installed between the rotor 1 8 and the rotor 2 15, a primary filter plate 6 and a secondary filter plate 7 are installed outside the rotor 1 8 and the rotor 2 15, respectively, and a primary filter base net 16 and a secondary filter base net 17 are respectively arranged on the primary filter plate 6 and the secondary filter plate 7;

[0032] Reference Figure 5 and Figure 6 As shown, a main drive gear plate 41 is arranged on the outer side of the discharge box 1 corresponding to the inner drum 5, each synchronous rod 44 extends to the two ends of the discharge box 1 and is respectively connected with a front driven drive plate 42 and a rear driven drive plate 43, a pair of main drive gear plates 41 and a plurality of groups of front driven drive plates 42 and rear driven drive plates 43 are meshed, a rotating rod 9 is installed in the middle of the inner drum 5, and the rotating rod 9 extends to the outer end of the inner drum 5 and is rotatably connected to the discharge box 1;

[0033] Reference Figure 1 and Figure 8As shown, a motor 20 is installed on the outside of the discharge box 1, the output end of the motor 20 is connected to the rotating frame 19, the inner end of the rotating frame 19 is connected to the outer side of the inner drum 5, and a motor 21 is arranged on the inner side of the motor 20, and the motor 21 drives the main drive gear plate 41 to rotate;

[0034] Structural principle: During the wet grinding process, the inner drum 5 is impacted by the wet material to complete the self-rotation, and the primary filter plate 6 and the secondary filter plate 7 are used to complete the filtering purpose during the self-rotation, so that the finished wet material after grinding can achieve the control of the discharge particle size after the pre-set filtering parameters, avoiding the problem that the quality of the finished grinding product is affected; an integrated module is added to perform intelligent parameter control on the above-mentioned discharge particle size control, and the control panel is built-in with the integrated module, which includes an opening detection unit, a variable angle analysis unit, a variable angle execution unit and a processor that are connected in communication;

[0035] The opening detection unit is used to obtain the expansion angle value ZJ and the rotation speed value HS of the primary filter plate and the secondary filter plate during wet grinding, and send the expansion angle value ZJ and the rotation speed value HS to the variable angle analysis unit through the processor, wherein the expansion angle value ZJ includes the gap angle between the adjacent groups of primary filter plates 6 and the secondary filter plates 7, specifically the angle value between the sides of the adjacent groups of primary filter plates 6 and the secondary filter plates 7, and the rotation speed value HS includes the rotation speed of the rotary filter assembly driven by the impact of the wet material in the return box;

[0036] The variable angle analysis unit immediately analyzes the wet grinding discharging process based on the received opening angle value and rotation speed value. The specific analysis process is: Construct the calculation formula of the opening coefficient KZ Wherein a>b>0, and k>0, a and b are preset proportional coefficients, k is a preset fault tolerance factor coefficient, and the start-up coefficient is compared and analyzed with the preset start-up threshold of the processor;

[0037] The comparison and analysis process is as follows: the variable angle analysis unit receives the deployment angle value and the rotation speed value, and obtains the opening and turning coefficient after numerical calculation of the deployment angle value and the rotation speed value. When the opening and turning coefficient is greater than the opening and turning threshold, it indicates that the wet material discharge speed of the current return material box 1 is reduced and a blockage occurs. At this time, a rising angle variable gap signal is generated and sent to the variable angle execution unit;

[0038] When the start-up coefficient is within the start-up threshold, it means that the wet material discharge speed in the current return box 1 is normal and no signal is generated;

[0039] When the opening coefficient is less than the opening threshold, it means that the discharge speed of the wet material in the current return box 1 is increased, and a no-load operation condition is generated. At this time, a decreasing angle gap signal is generated and sent to the angle-changing execution unit;

[0040] When the variable angle execution unit receives the angle-raising and gap-changing signal, it will send a control signal to the motor 21, and the motor 21 will drive the main drive gear disc 41 to rotate clockwise. At this time, the main drive gear disc 41 drives the driven drive disc 42 meshing with it to rotate, and the driven drive discs 42 on both sides rotate in opposite directions. Under the action of the synchronous rotation of several groups of rotary filter components, the "angle-raising" action with the gap between the primary filter plate 6 and the second filter plate 7 as the "angle" is achieved, that is, the expansion of the single group of filter gaps; the synchronous motor 1 20 is started, and the motor 1 20 drives the inner drum 5 to rotate, and an external force is applied to the rotary filter component while the wet material impacts the rotary filter component, thereby finally improving the smooth filtering effect of the discharge particle size and avoiding blockage;

[0041] When the variable angle execution unit receives the angle reduction gap change signal, it will send a control signal to the motor 21. The motor 21 drives the main drive gear plate 41 to rotate counterclockwise. At this time, the main drive gear plate 41 drives the driven drive plate 42 meshing with it to rotate, and the driven drive plates 42 on both sides rotate in opposite directions. Under the action of the synchronous rotation of several groups of rotary filter components, a "lowering angle" action with the gap between the primary filter plate 6 and the second filter plate 7 as the "angle" is achieved, that is, the reduction of the single group of filter gaps; the starting action of the motor 1 20 is stopped synchronously, and the inner drum 5 completes the rotation action only under the action of the wet material impacting the rotary filter component, and completes effective filtration in combination with the multiple filtering structures of the primary filter plate 6 and the second filter plate 7.

[0042] Basic principle: For the wet material discharge process in the wet grinding process, the integrated module is combined with the structural design of the variable-angle rotary filter component. After the wet material is discharged, the current filtration speed can be intelligently determined according to the expansion angle and rotation speed of the rotary filter component in the discharge box. Combined with the parameter determination of the expansion angle value and the rotation speed value, the control signal output is realized by the opening coefficient control, and finally the expansion angle adjustment and rotation speed adjustment of the rotary filter component are completed to achieve dynamic adjustment of uniform filtration and discharge; at the same time, it can also effectively prevent the problem of low wet material discharge efficiency caused by overload discharge or no-load operation, and finally achieve the precise control of the discharge particle size of the wet grinding wet material product by using the expansion angle adjustment and rotation speed adjustment method under the premise that the other parameters are fixed values, thereby improving the quality of the ground products.

[0043] Embodiment 2: This embodiment further optimizes the discharge structure of the discharge box 1 in Embodiment 1:

[0044] Reference Figure 3 As shown, the outer ends of the primary filter plate 6 and the secondary filter plate 7 fit with part of the structure inside the discharge box 1, and the primary filter base mesh 16 and the secondary filter base mesh 17 on the primary filter plate 6 and the secondary filter plate 7 are arranged in the feeding direction of the feed pipe 2 side;

[0045] A discharge gate 10 is horizontally installed on one side of the discharge box 1 close to the discharge pipe 3, and an overflow sealing plate 11 is movably installed on the upper end of the discharge gate 10. An electric push rod 12 is installed on the upper end of the discharge box 1 corresponding to the discharge pipe 3, and a connecting rod 13 connected to the overflow sealing plate 11 is installed on the output end of the electric push rod 12.

[0046] It should be noted that: refer to Figure 3 , Figure 4 and Figure 7 As shown, the primary filter base net 16 and the secondary filter base net 17 are both attached and detachable. When the wet material enters the discharge box 1 through the feed pipe 2, it directly impacts the primary filter base net 16 or the secondary filter base net 17, and the primary filter base net 16 and the secondary filter base net 17 are driven to rotate under the continuous impact, thereby completing the filtration, and the discharge particle size is effectively and accurately controlled according to the filter hole diameters of the primary filter base net 16 and the secondary filter base net 17;

[0047] In addition, refer to Figure 1 and Figure 3 As shown, during the discharging process after wet grinding, due to the particle size of the wet material itself, overflow control is performed during the filtration process to ensure that the discharge box 1 always maintains a uniform water level. Specifically, the electric push rod 12 drives the overflow sealing plate 11 and the discharge gate plate 10 to control whether they are closed or not. When the particle size meets the requirements, the discharge gate plate 10 is immediately opened to release all the wet materials.

[0048] Embodiment 3: This embodiment combines Embodiment 1 and Embodiment 2. The use process of the present invention is "the discharge of wet grinding is usually discharged together with the grinding aid". The process and principle of the present invention are as follows:

[0049] Step 1: The wet material enters the discharge box 1 through the feed pipe 2, and the impact rotary filter assembly completes the rotation, and the integrated module obtains the expansion angle value and the rotation speed value through the photoelectric sensor and the camera;

[0050] Step 2: According to the parameter values ​​obtained in real time in the above step 1, substitute them into the opening coefficient calculation formula to obtain the opening coefficient, and compare the opening coefficient with the opening threshold to obtain the rising angle variable gap signal and the falling angle variable gap signal, and synchronously control the motor 1 20 and the motor 2 21 to adjust the deployment angle and the rotation speed respectively;

[0051] Step 3: In step 2, when the angle-raising gap-changing signal is output, a control signal is sent to the motor 21, and the motor 21 drives the main drive gear disc 41 to rotate clockwise. At this time, the main drive gear disc 41 drives the driven drive disc 42 meshing therewith to rotate, and the driven drive discs 42 on both sides rotate in opposite directions. Under the action of the synchronous rotation of several groups of rotary filter components, an "angle-raising" action with the gap between the primary filter plate 6 and the second filter plate 7 as the "angle" is achieved, that is, the expansion of a single group of filter gaps; the synchronous motor 1 20 is started, and the motor 1 20 drives the inner drum 5 to rotate, and an external force is applied to the rotary filter component while the wet material impacts the rotary filter component, thereby finally improving the smooth filtering effect of the discharge particle size and avoiding blockage;

[0052] Step 4: In step 2, when the angle-reducing gap-changing signal is output, a control signal is sent to the motor 21, and the motor 21 drives the main drive gear disc 41 to rotate counterclockwise. At this time, the main drive gear disc 41 drives the driven drive disc 42 meshing therewith to rotate, and the driven drive discs 42 on both sides rotate in opposite directions. Under the action of the synchronous rotation of several groups of rotary filter components, a "angle-reducing" action with the gap between the primary filter plate 6 and the second filter plate 7 as the "angle" is achieved, that is, the reduction of the single group of filter gaps; the starting action of the motor 1 20 is synchronously stopped, and the inner drum 5 completes the rotation action only under the action of the wet material impacting the rotary filter component, and completes effective filtration in combination with the multiple filtering structures of the primary filter plate 6 and the second filter plate 7;

[0053] In summary: In combination with Examples 1, 2 and 3, it can be seen that the present invention is different from the conventional wet grinding discharging structure in that: on the one hand, through the integrated module combined with the structural design of the variable-angle rotary filter assembly, the current filtration speed can be intelligently determined according to the expansion angle and rotation speed of the rotary filter assembly in the discharge box after the wet material is discharged, and the parameter determination of the expansion angle value and the rotation speed value is combined to realize the output of the control signal by the opening coefficient control, and finally the expansion angle adjustment and rotation speed adjustment of the rotary filter assembly are completed to achieve dynamic adjustment of uniform filtration and discharge; on the other hand, it can also effectively prevent the problem of low wet material discharge efficiency caused by overload discharge or no-load operation, and finally achieve the precise control of the discharge particle size of the wet grinding wet material product by using the expansion angle adjustment and rotation speed adjustment methods under the premise that the other parameters are fixed values, thereby improving the quality of the ground products.
