Description

Technical Field

[0001] The invention belongs to the technical field of ceramic product mixers, and in particular, relates to a mixer and a method for producing ceramic products. Background Art

[0002] Before sintering ceramic products, the raw materials need to be evenly mixed. The traditional mixing methods include manual mixing, ball milling mixing and mechanical mixing. For manual mixing, multiple raw material powders are poured into a mixer for mixing to make the multiple powders evenly mixed, and then the materials are repeatedly sieved with a fine-mesh sieve to sieve out the required particle size, and the uniformity of the powder is determined during sieving. This method not only requires a lot of manpower and increases cost investment, but also has strict requirements on the type and particle size of the powder; However, when artificial mixing is used, the mixing uniformity is poor, and the sintered product is prone to unevenness, resulting in product scrapping and increased costs. For ball milling, the uniformity of mixing is greatly improved compared with manual mixing, but some sintered products still have particle agglomeration, indicating that the uniformity of the mixing process does not meet the theoretical requirements. At the same time, one ball milling takes a long time and the powder is limited, which is suitable for experimental research and development but not for mass production, thus causing production limitations. For mechanical mixing, the mixing equipment used in the ceramic industry includes high-speed mixers. Although the loading capacity is large, powder agglomeration still occurs. At the same time, high-speed mixers cannot further reduce the powder particles. Because we propose a mixer that can mix the powder evenly, avoid powder agglomeration, and solve the problem of different particle sizes. Summary of the invention

DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention. Example

[0018] Reference Figure 1-Figure 12 A mixer for producing ceramic products, comprising a mounting frame 1, and also comprising: an inner cylinder 11, a middle cylinder 12, and an outer cylinder 13 which are sleeved in sequence, wherein the inner cylinder 11 is located in the middle cylinder 12, and the middle cylinder 12 is located in the outer cylinder 13, and the inner cylinder 11 is connected to the mounting frame 1 through a fixing rod 15 for supporting and fixing the inner cylinder 11; a stirring and lifting mechanism, located in the inner cylinder 11, for transporting the powder in the inner cylinder 11 to the upper opening of the inner cylinder 11 when stirring; a mesh screen 14, arranged between the inner cylinder 11 and the middle cylinder 12, for screening the powder; a through slot 12 00, the circumference is opened on the middle cylinder 12, so that the agglomerated powder passes through the middle cylinder 12 and enters between the middle cylinder 12 and the outer cylinder 13; the folded wall 131 is respectively opened on the inner wall of the outer cylinder 13 and the outer wall of the middle cylinder 12, and a folded grinding channel 132 is formed between the folded wall 131 on the inner wall of the outer cylinder 13 and the folded wall 131 on the outer wall of the middle cylinder 12, so that when the folded wall 131 on the inner wall of the outer cylinder 13 and the folded wall 131 on the outer wall of the middle cylinder 12 are close to or away from each other, the agglomerated powder entering is dispersed and rubbed through the folded wall 131; When the device is used, the powder materials required for various ceramic products are poured into the inner cylinder 11, and the stirring and lifting mechanism is activated to stir the powder materials in the inner cylinder 11, so that the powder materials in the inner cylinder 11 are lifted toward the upper opening of the inner cylinder 11, that is, the powder materials in the inner cylinder 11 overflow from the upper opening of the inner cylinder 11; When the lifted powder reaches the opening of the inner cylinder 11, the powder falls on the mesh 14 between the inner cylinder 11 and the middle cylinder 12. The powder that meets the particle size of the mesh 14 passes through the mesh 14, while the agglomerated powder and the powder with a larger particle size are blocked by the mesh 14 and then enter the folded line grinding channel 132 between the outer cylinder 13 and the middle cylinder 12 through the through groove 1200. After entering, when the fold line wall 131 on the inner wall of the outer cylinder 13 and the fold line wall 131 on the outer wall of the middle cylinder 12 are close to or away from each other, a grinding effect will be produced on the powder. Figure 5 As shown, when the fold line wall 131 on the inner wall of the outer cylinder 13 and the fold line wall 131 on the outer wall of the middle cylinder 12 are close to each other, the spacing between the adjacent wall surfaces on the fold line wall 131 will increase and decrease, and the powder on the portion where the spacing decreases will disperse the agglomerated powder in the process of reducing the spacing, and at the same time, an upward rubbing effect will be generated between the wall surfaces where the spacing decreases, and then the area where the spacing increases will turn into a spacing decrease, and the powder in the area will be rubbed again, rubbing the powder particles into powder with a small particle size, thereby changing the powder particle size, making the powder particle size uniform and easier to mix evenly.

[0019] In one embodiment, the stirring and lifting mechanism includes a spiral blade 112 mounted on a main shaft 111, one end of the main shaft 111 is rotatably connected to the bottom wall of the inner cylinder 11, and the other end of the main shaft 111 is fixedly connected to the output end of a first motor 113 mounted on the mounting frame 1; The first motor 113 drives the main shaft 111 to rotate, and the main shaft 111 drives the spiral blade 112 to rotate, so that the powder in the inner cylinder 11 is lifted up by the spiral blade 112, that is, transported upward, and the various powders in the inner cylinder 11 are stirred during the transportation process; At the same time, when a variety of powders are poured into the inner cylinder 11, the main shaft 111 is driven to reverse, so that the spiral blades 112 stir the powders in the inner cylinder 11 while rotating without generating a lifting effect, so that the powders are first stirred in the inner cylinder 11 and then lifted.

[0020] In one embodiment, the mesh screen 14 is inclined, the mesh screen 14 is located below the through slot 1200, and the middle cylinder 12 is higher than the inner cylinder 11; The mesh screen 14 is arranged to be inclined, and a certain height difference is formed between the end of the mesh screen 14 inclined toward the outer cylinder 13 and the through groove 1200, so that the powder falling from the inner cylinder 11 onto the mesh screen 14 is first concentrated on the mesh screen 14, and avoids directly entering the fold line grinding channel 132; By setting the height of the middle cylinder 12 to be higher than that of the inner cylinder 11, the powder overflowing from the inner cylinder 11 can be shielded to avoid direct overflow into the fold line grinding channel 132, thereby ensuring the subsequent separation effect of the agglomerated powder and the grinding effect of larger particles.

[0021] In one embodiment, a connecting frame 116 is installed on the main shaft 111 through a limiting groove, and the connecting frame 116 is fixedly connected to the outer cylinder 13. A second motor 118 is symmetrically fixedly connected to the mounting frame 1, and a first eccentric wheel 119 is fixedly connected to the output end of the second motor 118. An annular surface 117 is provided on the connecting frame 116, and the first eccentric wheel 119 corresponds to the annular surface 117. A connecting disk 114 is fixedly connected to the main shaft 111, and a first spring 115 is sleeved between the connecting disk 114 and the connecting frame 116. One end of the first spring 115 is fixedly connected to the connecting disk 114, and the other end of the first spring 115 is fixedly connected to the connecting frame 116, so that when the main shaft 111 drives the outer cylinder 13 to rotate, the first eccentric wheel 119 reciprocates to push the outer cylinder 13 to move up and down; In this embodiment, the mesh screen 14 is fixedly connected to the middle cylinder 12 and the inner cylinder 11 respectively, and the inner cylinder 11 is fixedly connected to the mounting frame 1 via a fixing rod 15; Reference Figure 3 , by starting the second motor 118, the second motor 118 drives the first eccentric wheel 119 to rotate, and the first eccentric wheel 119 reciprocates to push the annular surface 117 on the connecting frame 116; By symmetrically opening limiting grooves on the outer wall of the main shaft 111, the connecting frame 116 is symmetrically fixedly connected to the limiting blocks on the inner wall of the main shaft 111, and the limiting blocks are slidably connected in the limiting grooves, so that when the main shaft 111 rotates, the connecting frame 116 can be driven to rotate together, and when the first eccentric wheel 119 reciprocates to push the connecting frame 116, the connecting frame 116 can slide on the main shaft 111, and the first spring 115 is provided to facilitate the reset of the connecting frame 116, thereby making the outer cylinder 13 reciprocate up and down. This facilitates the fold line wall 131 on the inner wall of the outer cylinder 13 to approach the fold line wall 131 on the outer wall of the middle cylinder 12, and facilitates the rubbing effect on the powder in the fold line rubbing channel 132. At the same time, the outer cylinder 13 can further grind the powder in a rotating state to reduce the particle size and meet the required requirements.

[0022] In one embodiment, referring to Figure 5 , Figure 6 , Figure 8 A third motor 17 is installed on the inner cylinder 11, and a second eccentric wheel 171 is fixedly connected to the output end of the third motor 17. The second eccentric wheel 171 corresponds to the bottom of the middle cylinder 12 and is used to push the middle cylinder 12 to move up and down; The connecting frame 116 is fixedly connected to the outer cylinder 13 and the main shaft 111 respectively, so that when the main shaft 111 rotates, the outer cylinder 13 is driven to rotate through the connecting frame 116. One end of the mesh screen 14 is fixedly connected to the middle cylinder 12. A slider is symmetrically installed at one end of the mesh screen 14 close to the inner cylinder 11. At the same time, a slide groove is symmetrically opened on the outer wall of the middle cylinder 12, and the slider is slidably connected in the slide groove. When the third motor 17 is started, the third motor 17 drives the second eccentric wheel 171 to rotate, so that the second eccentric wheel 171 reciprocates and drives the middle cylinder 12, so that the middle cylinder 12 reciprocates up and down, thereby conveniently driving the folded wall 131 on the outer wall of the middle cylinder 12 to approach or move away from the folded wall 131 on the inner wall of the outer cylinder 13, thereby producing an effect of rubbing the powder in the folded grinding channel 132 upwards, and at the same time, in conjunction with the rotation of the outer cylinder 13, further improving the grinding effect of the powder, thereby improving the uniformity of the powder mixing; At the same time, the reciprocating up and down motion of the middle cylinder 12 can generate vibration, which further promotes the powder on the mesh screen 14 to quickly pass through the mesh screen 14. At the same time, under the vibration, the powder accumulated on the mesh screen 14 can be stratified under the vibration, so that the agglomerated powder is located at the top, which further promotes the powder that falls on the mesh screen 14 of the inner cylinder 11 to quickly pass through the mesh screen 14 for screening, and at the same time facilitates the agglomerated powder and powder with larger particles to enter the fold line grinding channel 132 through the through groove 1200, thereby improving the screening effect.

[0023] In one embodiment, a plurality of mounting grooves 121 are provided on the circumference of the folded wall 131 of the middle cylinder 12, a grinding plate 122 is slidably connected in the mounting groove 121, the grinding plate 122 is connected to the mounting groove 121 via a second spring 126, and a grinding groove 123 is provided on the grinding plate 122, so that when the folded wall 131 on the inner wall of the outer cylinder 13 and the grinding plate 122 are close to each other, the powder in the folded grinding channel 132 is rubbed into round particles; Reference Figure 5 When the folded walls 131 on the middle cylinder 12 and the outer cylinder 13 are close to each other, the distance between the wall surfaces of the folded walls 131 where the grinding plate 122 is located is reduced. At this time, the powder located between the grinding plate 122 and the wall surfaces of the folded walls 131 on the inner wall of the outer cylinder 13 will be squeezed into the grinding groove 123. The grinding groove 123 is a semicircular arc groove concave inwardly into the grinding plate 122. The powder entering the grinding groove 123 will be rubbed when the wall surfaces of the folded walls 131 are close to each other. On the one hand, while reducing the particle size, the powder becomes rounded and the edges and corners are reduced, thereby improving the fluidity of the powder. When mixed with other powders, the fluidity can be improved, making it easier to stir evenly.

[0024] An installation cavity is provided on the inner wall of the middle cylinder 12, in which a piston cylinder 124 is installed, a piston rod 1240 having a piston plate at one end is slidably connected in the piston cylinder 124, a first air outlet pipe 12412 is provided in the piston rod 1240, an exhaust hole 125 is provided in the grinding plate 122, one end of the exhaust hole 125 leads to the grinding groove 123, the first air outlet pipe 12412 is connected to the exhaust hole 125 at one end away from the piston cylinder 124, a first air inlet pipe 12411 is installed on the piston cylinder 124, and is connected to the first chamber 1241 of the piston cylinder 124, and a first one-way valve is provided in the first air inlet pipe 12411 and the first air outlet pipe 12412; When the fold line wall 131 is close to each other, the powder between the grinding plate 122 and the fold line wall 131 on the inner wall of the outer cylinder 13 will squeeze the grinding plate 122, so that the grinding plate 122 slides into the mounting groove 121. At this time, one end of the grinding plate 122 will push the piston rod 1240, and the piston rod 1240 squeezes the gas in the first chamber 1241. The gas enters the first air outlet pipe 12412 and enters the exhaust hole 125, and is discharged from the exhaust hole 125, so as to blow away the powder in the grinding groove 123 and avoid affecting the grinding of large particles of powder. When the grinding plate 122 and the fold line wall 131 are separated from each other, the grinding plate 122 is reset under the thrust of the second spring 126, and the piston rod 1240 is pulled at the same time, so that the first air inlet pipe 12411 takes air into the first chamber 1241; In one embodiment, a thrust spring is arranged in the first chamber 1241, and the two ends of the thrust spring are respectively fixedly connected to the piston plate of the piston rod 1240 and the bottom wall of the piston cylinder 124. The piston rod 1240 is attached to one end of the grinding plate 122, which can facilitate the arrangement of multiple piston cylinders 124 on the inner cylinder 11 to provide more gas, and at the same time facilitate the grinding plate 122 to push the piston rod 1240 to slide when entering the mounting groove 121.

[0025] A second air inlet pipe 12421 and a second air outlet pipe 12422 are installed on the piston cylinder 124. The second air inlet pipe 12421 and the second air outlet pipe 12422 both lead to the second chamber 1242 of the piston cylinder 124. One end of the second air outlet pipe 12422 away from the piston cylinder 124 faces the mesh screen 14. The first air inlet pipe 12411 and the second air inlet pipe 12421 both lead to the middle cylinder 12. The second air inlet pipe 12421 and the second air outlet pipe 12422 are both provided with a second one-way valve. When the grinding plate 122 and the folding wall 131 are separated from each other, the grinding plate 122 is reset under the thrust of the second spring 126, and the piston rod 1240 is reset together, and the gas in the second chamber 1242 is squeezed, and the gas is discharged through the second gas outlet pipe 12422 and blown toward the mesh screen 14, accelerating the screening of the materials on the mesh screen 14; At the same time, the first air inlet pipe 12411 and the second air inlet pipe 12421 are both connected to the middle cylinder 12, so that when air is introduced into the first chamber 1241 and the second chamber 1242, the gas in the area between the middle cylinder 12 and the mesh screen 14 can be sucked, so that the powder on the mesh screen 14 can pass through quickly and then reach the middle cylinder 12, thereby speeding up the screening.

[0026] It should be understood that one end of the first air inlet pipe 12411 and the second air inlet pipe 12421 are both provided with filter cotton, which can prevent powdered powder from being sucked into the piston cylinder 124.

[0027] The end of the piston cylinder 124 extends into the middle cylinder 12, and the piston cylinder 124 partially extends into the middle cylinder 12, so that when the mixed powder on the mesh screen 14 passes through the mesh screen 14, it can be blocked by the piston cylinder 124, further improving dispersion, thereby improving the mixing effect.

[0028] The end of the outer cylinder 13 is open, and the lower end of the middle cylinder 12 is open. A bottom plate 120 is installed at the lower end of the middle cylinder 12 to seal the lower end opening of the middle cylinder 12. After the powder is mixed, the bottom plate 120 is removed to facilitate discharge. A collecting box 16 is placed at the lower end of the outer cylinder 13 and the middle cylinder 12 to facilitate the collection of discharged powder.

After the mixing is completed, it is discharged for use.

[0030] The present invention produces a rubbing effect on powder when the folded wall 131 on the inner wall of the outer cylinder 13 and the folded wall 131 on the outer wall of the middle cylinder 12 are close to or away from each other; when the folded wall 131 on the inner wall of the outer cylinder 13 and the folded wall 131 on the outer wall of the middle cylinder 12 are close to each other, the spacing between adjacent wall surfaces on the folded wall 131 will increase and decrease, and the powder on the portion with reduced spacing will squeegee the agglomerated powder in the process of reducing the spacing, and at the same time, an upward rubbing effect will be generated between the wall surfaces with reduced spacing, and then the area with increased spacing will turn into a reduced spacing, and the powder in the area will be rubbed again, and the powder particles will be rubbed into powder with small particle size, and then the particle size of the powder will be changed, so that the powder particle size is uniform and easier to mix evenly.
