Description

Technical Field

[0001] The present invention relates to the technical field of solid-liquid mixing, in particular to a stirring device for solid-liquid mixing. Background Art

[0002] Solid-liquid mixing is the process of blending liquid additives with solid polymer materials through physical or chemical means. It mainly includes two forms: preliminary mixing of solid polymer with liquid additives in an unmelted state, and composite blending of molten polymer with solid additives. This process is widely used in polymer material processing (such as the mixing of PVC and plasticizer DOP) and new energy battery manufacturing (such as the construction of solid-liquid electrolyte systems in semi-solid batteries). The core technology achieves interface mechanical matching and optimizes material properties through microfluidic encapsulation, graded curing and other means.

[0003] In the prior art, when mixing solids and liquids, the mixture often needs to be stirred to ensure that the solids and liquids are fully mixed. However, the liquid vortexes formed by traditional stirring methods generally have a single direction. Therefore, when mixing solids with larger particle sizes, the mixing speed is slow due to the particle size itself. At this time, the single liquid vortex direction will cause the solid particles that have not been mixed in time to continuously dock with the direction of the liquid, and the fixed particles will continue to accumulate into piles or clumps. The accumulated particles and the agglomerated particles are not easy to be broken up and mixed, which will affect the effect of solid-liquid mixing. Summary of the Invention

At this time, since the use spacing of the mixing stirring plates is adjusted and reset under the action of the rebound force of multiple first springs, the originally fixed state of the liquid turbine is changed, and the spacing adjustment operation is repeatedly performed as the shaft tube continues to rotate, so that the direction of the liquid turbine can be repeatedly changed, and the effect of preventing materials with larger particle sizes from accumulating and agglomerating due to the direction of the liquid turbine is achieved.

[0013] By adopting the above technical solution, when the shaft tube rotates, the solid material is passed through the feeding hopper into the interior of the shaft tube, and then the filter bucket inside the shaft tube will separate the large particles and small particles of material, and the rotation of the shaft tube will cause the filter bucket to rotate, while the position of the push plate is always in a fixed state, and then the solid material particles inside the shaft tube will be continuously turned over, thereby preventing the filter bucket from being blocked. At this time, large particles of material will be accumulated above the filter bucket, and small particles of material will enter the bottom of the filter bucket, and then by accelerating the rotation speed of the shaft tube, the multiple sealing plates outside the shaft tube will generate centrifugal force, and then under the cooperation of centrifugal force and counterweight block, when the centrifugal force is greater than the rebound force of the third spring, the sealing plate will rotate open, and at this time the solid particle raw material inside the shaft tube will enter the liquid inside the mixing tank, and then because the large particles of material are above the filter bucket, the large particles of material can be prevented from sinking to the bottom during mixing, and releasing the solid material inside the liquid can prevent the phenomenon that the lighter material particles float on the top of the liquid and are difficult to mix.

[0024] In summary, the present invention mainly has the following beneficial effects:

[0025] 1. The present invention rotates through the shaft tube, and then the two adjustment rings on the outside of the shaft tube will drive multiple first connecting rods and multiple second connecting rods to rotate at the same time, and then the multiple mixing and stirring plates will stir and mix the liquid and solid raw materials inside the mixing tank. During this process, the multiple positioning rods will be continuously squeezed and moved downward, thereby driving the multiple first connecting rods and multiple second connecting rods to rotate, and changing the use spacing between the multiple mixing and stirring plates, so that the originally fixed state of the liquid turbine is changed, and the spacing adjustment operation is repeatedly performed as the shaft tube continues to rotate, so that the direction of the liquid turbine can be repeatedly changed, and the effect of preventing materials with larger particle sizes from accumulating and agglomerating due to the direction of the liquid turbine is achieved.

[0026] 2. The present invention drives the gear to rotate by the driving shaft of the driving motor, and then under the gear meshing transmission action of the gear and the gear ring, the mounting cover drives the shaft tube to rotate, and then the first adjustment plate continuously contacts and squeezes the second adjustment plate. At this time, the second adjustment plate is subjected to downward pressure and drives the adjustment ring to move downward, and squeezes the first springs inside the multiple first mounting seats, and at the same time causes the multiple first connecting rods and the second connecting rods to rotate, changing the use spacing between the multiple mixing stirring plates, thereby preventing the solid particulate material from piling up and agglomerating, and improving its mixing effect.

[0027] 3. The present invention allows solid materials to enter the shaft tube through the feeding hopper as the shaft tube rotates. The filter hopper inside the shaft tube then separates large and small particles. The rotation of the shaft tube causes the filter hopper to rotate, while the push plate remains in a fixed position. The solid material particles inside the shaft tube are then continuously stirred, thereby preventing the filter hopper from clogging. Large particles are then accumulated above the filter hopper, while small particles enter the filter hopper below.

[0028] 4. The present invention accelerates the rotation speed of the shaft tube so that the multiple sealing plates outside the shaft tube generate centrifugal force. Then, under the cooperation of the centrifugal force and the counterweight block, when the centrifugal force is greater than the rebound force of the third spring, the sealing plate will rotate open. At this time, the solid particle raw materials inside the shaft tube will enter the liquid inside the mixing tank. Furthermore, since the large particles of material are above the filter bucket, the large particles of material can be prevented from sinking to the bottom during mixing. In addition, releasing the solid material inside the liquid can prevent the phenomenon that the lighter particles of the material float on the top of the liquid and are difficult to mix.

[0029] 5. The present invention drives the second connecting column and the inner wall cleaning plate through the rebound force of multiple second springs, so that they are always in contact with the inner wall of the mixing tank, and as the shaft tube rotates, the multiple inner wall cleaning plates clean the residual mixture on the inner wall of the mixing tank. The rebound force of the fourth spring makes the bottom cleaning plate always in contact with the bottom of the mixing tank, and then cleans the residual mixture at the bottom of the mixing tank when the shaft tube rotates.

[0030] 6. The present invention heats the mixing tank and the liquid raw materials therein by using multiple heating tubes at the same time, thereby meeting the mixing operation of some materials that require high-temperature mixing. When the liquid raw materials inside the mixing tank are heated, high temperature and high pressure phenomena will be generated, and then the high-pressure gas inside the mixing tank can be discharged through the pressure relief valve to prevent explosion.

The outer circular wall of the shaft tube 11 is rotatably connected to a plurality of sealing plates 20, and the position of the sealing plates 20 corresponds to the position of the discharge holes 44. The outer circular wall of the sealing plate 20 is fixedly installed with a counterweight block 39, and the outer circular wall of the shaft tube 11 is fixedly installed with a second mounting seat 32. The interior of the second mounting seat 32 is slidably connected with an arc-shaped connecting rod 37, one end of the arc-shaped connecting rod 37 is fixedly installed with the counterweight block 39, and the outer circular wall of the arc-shaped connecting rod 37 is movably sleeved with a third spring 38. A positioning rod 29 is fixedly installed inside the feeding hopper 3, and a pushing plate 30 is fixedly installed on the bottom surface of the positioning rod 29. When the shaft tube 11 rotates, the solid material passes through the feeding hopper 3 into the interior of the shaft tube 11, and then the filter bucket 31 inside the shaft tube 11 will separate the large particles and the small particles.

At this time, large particles of material will be accumulated above the fractionating filter hopper 31, and small particles of material will enter the bottom of the fractionating filter hopper 31, and then by accelerating the rotation speed of the shaft tube 11, the multiple sealing plates 20 outside the shaft tube 11 will generate centrifugal force, and then under the cooperation of the centrifugal force and the counterweight block 39, when the centrifugal force is greater than the rebound force of the third spring 38, the sealing plate 20 will rotate open, and at this time the solid particle raw material inside the shaft tube 11 will enter the liquid inside the mixing tank 1, and since the large particles of material are above the fractionating filter hopper 31, the large particles of material can be prevented from sinking to the bottom during mixing, and releasing the solid material in the liquid can prevent the phenomenon that the lighter particles of material float on the top of the liquid and are difficult to mix.

[0045] Based on the above embodiment, refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 10The outer circular wall surface of the shaft tube 11 is fixedly sleeved with a positioning sleeve 13, and the outer circular wall surface of the positioning sleeve 13 is fixedly mounted with a plurality of first mounting caps 15. The inner circular wall surface of the first mounting cap 15 is movably sleeved with a second spring 35. The interior of the first mounting cap 15 is slidably connected with a second connecting column 36. One end of the second connecting column 36 is fixedly mounted with an inner wall cleaning plate 16. The second connecting column 36 and the inner wall cleaning plate 16 are driven by the rebound force of the plurality of second springs 35 to always fit the inner wall of the mixing tank 1. As the shaft tube 11 rotates, multiple inner wall cleaning plates 16 clean the residual mixture on the inner wall of the mixing tank 1. The outer circular wall of the shaft tube 11 is fixedly sleeved with a mounting bracket 18. The bottom surface of the mounting bracket 18 is fixedly mounted with a plurality of second mounting caps 40. The inner circular wall of the second mounting cap 40 is movably sleeved with a fourth spring 41. The inner circular wall of the second mounting cap 40 is slidably connected with a third connecting column 42. The bottom surface of the third connecting column 42 is fixedly mounted with a bottom cleaning plate 43. The rebound of the fourth spring 41 causes the bottom cleaning plate 43 to be fixedly mounted.

The outer circular wall of the mixing tank 1 is fixedly sleeved with several mounting covers 7, and the interior of the mounting cover 7 is fixedly installed with a heating pipe 8.

[0046] Working principle: Please refer to Figures 1-10As shown, when in use, the staff adds the liquid material into the interior of the mixing tank 1 through the liquid inlet pipe 4, and then the staff drives the shaft tube 11 to rotate by the driving motor 6, and then the staff adds the solid material into the interior of the shaft tube 11 through the feeding hopper 3, and then the filter bucket 31 inside the shaft tube 11 will separate the large particles and small particles of the material, and because the rotation of the shaft tube 11 will cause the filter bucket 31 to rotate, and the position of the push plate 30 is always in a fixed state, and the solid material particles inside the shaft tube 11 will be continuously turned over, thereby preventing the filter bucket 31 from being blocked. At this time, the large particles of material will be accumulated in the filter bucket 3 1, while small particles of material will enter the bottom of the filter bucket 31, and then by accelerating the rotation speed of the shaft tube 11, the multiple sealing plates 20 outside the shaft tube 11 will generate centrifugal force. Then, under the cooperation of the centrifugal force and the counterweight block 39, when the centrifugal force is greater than the rebound force of the third spring 38, the sealing plate 20 will rotate open, and the solid particle raw material inside the shaft tube 11 will enter the liquid inside the mixing tank 1. Since the large particles of material are above the filter bucket 31, the large particles of material can be prevented from sinking to the bottom during mixing, and the solid material released from the liquid can prevent the lighter particles of material from floating on the top of the liquid and being difficult to mix.

[0047] The driving shaft of the driving motor 6 drives the gear 27 to rotate, and then under the gear meshing transmission action of the gear 27 and the gear ring 26, the mounting cover 25 drives the shaft tube 11 to rotate, and then the first adjusting plate 28 will continuously contact the second adjusting plate 45 and squeeze the second adjusting plate 45. At this time, the second adjusting plate 45 is subjected to downward pressure and drives the adjusting ring 14 to move downward, and squeezes the first springs 33 inside the multiple first mounting seats 21, and at the same time causes the multiple first connecting rods 22 and the second connecting rods 23 to rotate, changing the use spacing between the multiple mixing and stirring plates 24, and then when the first adjusting plate 28 and the second adjusting plate 45 are intertwined, the rebound force of the multiple first springs 33 will drive the multiple mixing and stirring plates 24 to reset, and then with the continuous rotation of the shaft tube 11, this movement step will continue to occur, and at this time the direction of the liquid turbine inside the mixing tank 1 will continue to change, thereby preventing the accumulation and agglomeration of solid particulate materials and improving its mixing effect;

[0048] When the materials inside the mixing tank 1 are mixed, the staff can discharge the materials through the discharge valve 12. At this time, the bottom cleaning plate 43 is always attached to the bottom of the mixing tank 1 through the rebound force of the fourth spring 41, and then the residual mixture at the bottom of the mixing tank 1 is cleaned when the shaft tube 11 rotates. The second connecting column 36 and the inner wall cleaning plate 16 are driven by the rebound force of multiple second springs 35 to always attach to the inner wall of the mixing tank 1. As the shaft tube 11 rotates, the multiple inner wall cleaning plates 16 clean the residual mixture on the inner wall of the mixing tank 1.
