Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of sand mill, in particular to an intelligent sand mill based on zirconia bead processing and a method thereof. BACKGROUND

[0002] The sand mill is a device for further grinding of broken mineral materials, and a wear-resistant liner is attached to the inner wall of the mill cylinder. The stirring disc is arranged on the mill shaft penetrating into the cylinder cavity. The mineral slurry is stably conveyed into the mill through the hose pump after being separated. The stirring disc in the mill cylinder is driven by the main shaft to rotate at high speed, so that the high-hardness and wear-resistant grinding medium moves around the shaft and rotates. The mineral particles are subjected to the scouring force of the high-speed moving grinding medium to achieve the grinding process.

[0003] Referring to the horizontal sand mill for pesticide production disclosed in the patent application with the publication number CN118162255A, the present application relates to the technical field of sand mill. When the slurry after sanding is discharged, the small particles in the slurry are discharged, the small particles at the discharge position are reduced, the small particles in the large particles are concentrated too fast to the inside, and then discharged, reducing the sanding effect. By blocking the screen surface screen hole, the speed of the particles gathering to the center is limited during the process of discharging small particle slurry. The screen cylinder cooperates with the groove cylinder to avoid the discharge of small particles, reduce the small particles at the discharge position, and the small particles in the large particles are concentrated too fast to the inside. Subsequently, the discharge reduces the sanding effect. At the same time, the screen cylinder blocks the grinding medium, so that the grinding medium does not exist at the center, avoiding the influence of the grinding medium on the discharge of the slurry.

[0004] In the traditional sand mill, the uneven distribution of zirconia beads and the low efficiency of intermittent addition are the core problems that affect the grinding effect. The static feeding mode easily leads to local accumulation of zirconia beads in the sanding cylinder, causing material stress concentration and container wear. Manual batch addition causes production interruption. The existing technology mainly uses fixed guide plates or vibration assisted distribution, but cannot realize dynamic landing point adjustment. The impact force of vertical feeding can accelerate the breakage of zirconia beads, affecting the uniformity of slurry grinding. In addition, there is a lack of active control mechanism for the motion trajectory of zirconia beads, making it difficult to balance the contradiction between continuous feeding and uniform distribution.

[0005] Therefore, it is necessary to provide an intelligent sand mill based on zirconia bead processing and a method thereof to solve the above technical problems. SUMMARY

[0019] A method of an intelligent sanding machine based on zirconium oxide bead processing, comprising the following steps:

[0020] Step one: inflate the guide piece to expand it into the sanding cylinder;

[0021] Step 2: Select suitable zirconium beads according to the slurry and put them into the conveying cylinder through the feed funnel. The zirconium beads are continuously conveyed by the agitator inside the conveying cylinder.

[0022] Step 3: The zirconium beads that enter the grinding cylinder are continuously and evenly distributed inside the grinding cylinder by the guide.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] 1. Simultaneously, the zirconium beads entering the grinding cylinder are continuously and evenly distributed inside the cylinder by the guide component. At the same time, the transmission component drives the limiting component, causing the guide component to change its arc shape, thus continuously changing the drop point of the zirconium beads. When the slurry is introduced, the stirring component agitates the slurry and zirconium beads together, grinding the slurry. Finally, it is discharged through the slurry outlet pipe. The zirconium beads are more evenly distributed when added by the guide component, and it also ensures that personnel can continuously add zirconium beads, avoiding the need for intermittent addition in multiple batches, which affects efficiency.

[0026] 2. When the zirconium beads inside the conveying cylinder are conveyed by the conveying blades and fall onto the top of the guide airbag, the zirconium beads are fed along the arc-shaped edge of the guide airbag to avoid vertical feeding of the zirconium beads, which would cause them to accumulate and prevent local damage caused by long-term impact. The guide airbag can guide the zirconium beads to slide to both ends of the inside of the grinding cylinder, thereby achieving uniform distribution.

[0027] 3. The telescopic rod drives the rotating ring to reset and rotate, which in turn drives the winding drum to swing the limiting strip left and right at both ends of the guide airbag. This causes the recessed area to change, and the landing points of the zircon beads at both ends to continuously change, achieving uniform distribution while reducing collisions. The accumulation of zircon beads caused by the fixed limiting strip will lead to local stress concentration and accelerated wear of the material. The mechanical linkage mechanism transforms the continuous rotational motion into the periodic oscillation of the limiting strip, fundamentally solving the static accumulation problem. By dynamically controlling the displacement to change the landing point of the zircon beads, the following objectives are achieved: eliminating material accumulation caused by static recesses, reducing collision losses between zircon beads and the container, and improving the uniformity of zircon bead distribution.

[0046] The bottom of connecting barrel 5 is provided with limiting piece, the limiting piece is sleeved outside the guide, the bottom of connecting barrel 5 is provided with transmission part, and the transmission part drives the limiting piece to reciprocate.

[0047] In specific implementation, when the sand mill grinds the slurry, it mainly relies on the contact and collision of zirconium beads with the slurry, so the equipment needs to add zirconium beads during preparation, and the amount of zirconium beads added is about 60%-85% of the internal volume of the grinding barrel 2. When adding, it can be poured in batches through the hopper to avoid one-time accumulation, so it often takes a lot of time to add zirconium beads, affecting efficiency. At the same time, if the zirconium beads are added too fast, the zirconium beads may be directly thrown into the grinding cavity, which may cause the lining of the equipment, such as zirconium oxide or tungsten carbide coating, to break due to gravity impact, especially high-hardness zirconium beads such as yttrium-stabilized zirconium beads have greater instantaneous impact force on the cavity. Therefore, in this scheme, the guide is inflated to expand into the grinding barrel 2, and the appropriate zirconium beads are selected according to the slurry, which are thrown into the conveying barrel 4 through the feeding hopper 3, and the zirconium beads are continuously conveyed through the stirring member in the conveying barrel 4. At the same time, the zirconium beads entering the grinding barrel 2 are evenly distributed in the grinding barrel 2 through the guide, and the transmission member drives the limiting member to change the arc of the guide, so that the dropping point of the zirconium beads is continuously changed. The slurry is added, the stirring assembly stirs the slurry and the zirconium beads together, grinds the slurry, and finally discharges through the slurry outlet pipe 201. The zirconium beads are more evenly distributed when added through the guide, and personnel can continuously add zirconium beads, avoiding the need for multiple batches of intermittent addition, which affects efficiency.

[0048] In this embodiment, the stirring member includes a first inner gear ring 402 rotatably connected to the top end inside the conveying barrel 4, and the bottom of the first inner gear ring 402 is fixedly connected with a conveying blade 401, the conveying blade 401 is sleeved outside the connecting barrel 5, and the bottom end of the conveying blade 401 extends to the bottom end of the connecting barrel 5.

[0049] In specific implementation, when the zirconium beads enter the conveying barrel 4 through the feeding hopper 3, the driving motor is started, the output shaft of the driving motor drives the first gear 403 to rotate, the first gear 403 drives the meshingly connected first inner gear ring 402 to rotate, and the fixedly connected conveying blade 401 is driven to rotate when the first inner gear ring 402 rotates, so that the zirconium beads conveyed to the inside of the conveying barrel 4 through the conveying blade 401 are prevented from being blocked during conveying.

[0050] Implementation two: the top of the conveying cylinder 4 is fixedly connected with an air inlet pipe 603 for air inlet, the air inlet pipe 603 passes through the conveying cylinder 4 and extends to the inside of the connecting cylinder 5, the air inlet pipe 603 is connected with the outside air pump, the top of the conveying cylinder 4 is fixedly connected with an air outlet pipe 802, the air outlet pipe 802 extends to the inside of the connecting cylinder 5 and is connected with the connecting cylinder 5, the outside of the air outlet pipe 802 is provided with a control valve 803, and the control valve of the control valve 803 is fixedly connected with a rotating gear 804.

[0051] The guide includes a telescopic air bag 601 fixedly connected to the bottom of the connecting cylinder 5 and connected with the connecting cylinder 5, and the bottom of the telescopic air bag 601 is fixedly connected with a guide air bag 602 in communication, when the gas in the inside of the connecting cylinder 5 fills the inside of the telescopic air bag 601 and the guide air bag 602, the telescopic air bag 601 and the guide air bag 602 are inflated, and the guide air bag 602 extends to the inside of the sanding cylinder 2 and is unfolded.

[0052] In specific implementation, the outside air pump inflates the connecting cylinder 5, the gas in the inside of the connecting cylinder 5 is transported to the inside of the telescopic air bag 601, at this time, the telescopic air bag 601 is inflated downward, and the guide air bag 602 at the bottom of the telescopic air bag 601 is unfolded to both sides, similar to a tile shape, the zirconium beads in the inside of the conveying cylinder 4 are transported to the top of the guide air bag 602 by the conveying blade 401, the zirconium beads are discharged along the arc-shaped edge of the guide air bag 602, the vertical discharge of the zirconium beads is avoided, the accumulation is avoided, the local position is not damaged by long-time impact, the zirconium beads are caused to slide to both ends of the inside of the sanding cylinder 2 by the guide of the guide air bag 602, and thus uniform distribution is achieved.

[0053] Anti-accumulation design: the tile-shaped guide structure changes the motion track of the zirconium beads and eliminates the conical accumulation formed by the vertical discharge;

[0054] Wear protection: the air bag is used for buffering to reduce the direct impact of the zirconium beads on the cylinder;

[0055] Uniform distribution: the arc-shaped guide surface causes the material to be uniformly distributed along the circumference of the cylinder, and the grinding efficiency is improved.

[0056] Example three: the limiting piece includes a rotating ring 701, two oppositely arranged winding cylinders 703 are fixedly connected to the bottom of the rotating ring 701, a limiting strip 702 is arranged between the two winding cylinders 703, the two ends of the limiting strip 702 are wound into the inside of the winding cylinder 703, a clockwork spring is fixedly connected between the winding cylinder 703 and the limiting strip 702, when the guide air bag 602 is inflated, the limiting strip 702 tightens the guide air bag 602, and a constraint concave surface is formed on both sides of the guide air bag 602.

[0057] In actual implementation, since the guide air bag 602 needs to guide the zirconium beads to the two ends inside the sanding barrel 2, but the zirconium beads will slide to the two sides of the guide air bag 602, in the scheme, the limiting strip 702 is arranged, when the stretchable air bag 601 and the guide air bag 602 are inflated, the limiting strip 702 between the winding drums 703 is pulled to continuously extend, so that the limiting strip 702 is sleeved outside the guide air bag 602, the limiting strip 702 is tightened on the guide air bag 602, therefore, the position of the limiting strip 702 is lower than other positions, the zirconium beads will slide to the lower position, so that the zirconium beads can smoothly slide to the two ends inside the sanding barrel 2.

[0058] Has the following effects:

[0059] Dynamic limiting mechanism

[0060] When the stretchable air bag 601 and the guide air bag 602 are inflated synchronously, the limiting strip 702 is extended by the winding drum 703;

[0061] The limiting strip 702 adopts a flexible belt structure, and forms a ring-shaped constraint on the guide air bag under the action of air pressure.

[0062] The tightening effect causes the middle part of the guide air bag to be concave, and the gradient slope angle of the two sides is greater than or equal to 15°.

[0063] Fluid dynamics optimization

[0064] The motion trajectory of the zirconium beads conforms to the principle of minimum potential energy, and the zirconium beads preferentially slide along the low-potential energy path formed by the limiting strip 702.

[0065] The radial pressure of the limiting strip 702 needs to be controlled in the range of 0.3-0.5 MPa, to avoid excessive compression affecting the deformation of the air bag

[0066] In the embodiment, the transmission member includes a transmission ring 705, the transmission ring 705 is rotationally connected to the bottom of the connecting barrel 5, the transmission ring 705 is fixedly connected with the conveying blade 401 through a support plate, the transmission ring 705 is fixedly connected with a second inner gear ring 706, the second inner gear ring 706 is internally meshingly connected with a second gear 704, the second gear 704 is rotationally connected with the bottom of the connecting barrel 5, and the bottom of the second gear 704 is fixedly connected with a rotating disc 707.

[0067] The transmission member further includes a connecting rod 709, the connecting rod 709 is fixedly connected with the bottom of the connecting barrel 5, the connecting rod 709 is rotationally connected with a swing plate 712 outside, one end of the swing plate 712 extends to the bottom of the rotating disc 707, a sliding groove is formed in the outer side of the swing plate 712, the bottom of the rotating disc 707 is eccentrically fixedly connected with a sliding shaft 708, the sliding shaft 708 extends to the inside of the sliding groove and is slidingly connected with the swing plate 712, the other end of the swing plate 712 is fixedly connected with a telescopic rod 710, and the telescopic rod 710 is rotationally connected with the rotating ring 701 through a rotating shaft 711.

[0068] In particular implementation, when the recess caused by the limiting strip 702 is in the same position for a long time, local accumulation will inevitably occur. Therefore, in the present scheme, the conveying blade 401 drives the transmission ring 705 to rotate, the transmission ring 705 drives the second inner gear ring 706 fixedly connected inside to rotate, the second inner gear ring 706 meshes with the second gear 704, and then the second gear 704 rotates, when the second gear 704 rotates, the fixedly connected rotating disc 707 rotates, the sliding shaft 708 at the bottom of the rotating disc 707 drives the swing plate 712 to reciprocate around the connecting rod 709, when the connecting rod 709 deflects, the telescopic rod 710 drives the rotating ring 701 to reset and rotate, and then the winding drum 703 drives the limiting strip 702 to swing left and right at both ends of the guide air bag 602, and then the recess changes, so that the landing points of the zirconium beads at both ends change continuously, achieving uniform distribution while reducing collision. The accumulation of zirconium beads caused by the fixed limiting strip 702 will cause local stress concentration and accelerated wear of the material. The mechanical linkage mechanism converts continuous rotary motion into periodic swinging of the limiting strip, fundamentally solving the problem of static accumulation. By changing the landing point of the zirconium beads through dynamic displacement control, the following goals are achieved: eliminating material accumulation caused by static recess, reducing collision loss between zirconium beads and container, and improving zirconium bead distribution uniformity.

[0069] In the fourth embodiment, the top of the transmission ring 705 is fixedly connected with a magnetic ring 8, a through slot 801 is provided on the outer side of the connecting cylinder 5, and a magnetic inner gear ring 805 is rotatably connected inside the connecting cylinder 5. The magnetic inner gear ring 805 is magnetically adsorbed with the magnetic ring 8. The third gear 901 is meshingly connected inside the magnetic inner gear ring 805. The bottom of the third gear 901 is fixedly connected with the reciprocating screw rod 902. The connecting cylinder 5 is fixedly connected with the limiting frame 903 inside. The reciprocating screw rod 902 penetrates through the limiting frame 903 and is rotatably connected with the limiting frame 903. The limiting frame 903 is slidably connected with the sliding block 904 inside. The sliding block 904 is fixedly connected with the rack 905 outside. The rack 905 is meshingly connected with the rotating gear 804. When the rack 905 rises, the rotating gear 804 rotates, so that the rotating gear 804 controls the control valve 803 to open. The gas inside the connecting cylinder 5 is discharged through the gas outlet pipe 802.

[0070] In specific implementation, in order to ensure that the falling points at both ends of the guide air bag 602 are adjustable, the present scheme is provided with the gas outlet pipe 802 inside the connecting cylinder 5, and the gas outlet pipe 802 is provided with the control valve 803. When the control valve 803 is opened, the gas inside the connecting cylinder 5, the guide air bag 602 and the telescopic air bag 601 is overflowed, so that the guide air bag 602 is contracted. When the guide air bag 602 is contracted, the falling position of the zirconium beads gradually approaches the discharging position of the conveying cylinder 4. In the present scheme, the magnetic ring 8 is fixedly connected to the top of the transmission ring 705, the magnetic ring 8 drives the magnetic inner gear ring 805 to rotate through magnetic attraction, the magnetic inner gear ring 805 drives the third gear 901 to rotate, the third gear 901 drives the reciprocating screw rod 902 to rotate, and then the reciprocating screw rod 902 drives the sliding block 904 inside the limiting frame 903 to rise, the sliding block 904 drives the rack 905 to rise, and then the rack 905 drives the rotating gear 804 to rotate, so that the control valve 803 on the gas outlet pipe 802 is opened, the gas inside is continuously overflowed, the guide air bag 602 is contracted, and thus the position of the guided discharging of the zirconium beads is adjusted. In the later period, the guide air bag 602 and the telescopic air bag 601 can be contracted through the negative pressure of the air extraction device, so as to avoid affecting the treatment of the slurry of the grinding cylinder 2.

[0071] The working principle of the above scheme is as follows:

[0072] 1. Gas adjusting module

[0073] The gas outlet pipe 802 and the control valve 803 are as follows:

[0074] The gas outlet pipe inside the connecting cylinder 5 is provided with a control valve. When the control valve is opened, the gas inside the guide air bag 602 and the telescopic air bag 601 is discharged, so that the air bag is contracted, and the contraction degree is proportional to the overflow amount of the gas, so as to push the falling position of the zirconium beads to approach the discharging port of the conveying cylinder 4.

[0075] Negative pressure recovery design:

[0076] In the later period, the negative pressure of the air extraction device is formed, so that the air bag is completely contracted and adhered, and mechanical interference to the treatment of the slurry of the grinding cylinder 2 is avoided.

[0077] 2. Magnetic transmission mechanism

[0078] Power transmission chain:

[0079] The magnetic ring 8 on the top of the transmission ring 705 drives the magnetic inner gear ring 805 to rotate through magnetic attraction, and then realizes linear motion through the third gear 901→reciprocating screw rod 902→sliding block 904 inside the limiting frame 903.

[0080] Valve control linkage:

[0081] The rising sliding block 904 drives the rack 905 to move, drives the rotating gear 804 to rotate, and finally opens the control valve 803 of the air outlet pipe 802, forming an automatic response chain of "mechanical movement→gas release→air bag contraction".
