Description

Technical Field

[0001] The present application belongs to the technical field of stirring and mixing, and relates to a liquid raw material batching and mixing device. Background Art

[0002] Existing mixing devices for stirring and mixing high-viscosity liquids include a mixing barrel and a frame agitator. Various materials are put into the mixing barrel, and the frame agitator is rotated to stir the mixed materials. Compared with conventional stirring blades, frame agitators are mostly square-shaped. The frame agitator can stir a larger amount of materials, and the gap between it and the inner wall of the mixing barrel is smaller. It has a better stirring effect on the materials near the inner wall of the mixing barrel and is more suitable for stirring high-viscosity liquids.

[0003] However, when agitating, the frame agitator has a poor agitation effect in the middle area of ​​the frame agitator. Summary of the invention

[0004] Aiming at the problem that the existing frame-type agitator has poor stirring effect, a liquid raw material batching and mixing device is provided.

[0005] The present application provides a liquid raw material batching and mixing device, which is specifically implemented by the following technical solutions: A liquid raw material batching and mixing device comprises a mixing barrel, a stirring shaft, a stirring tube, a first motor and a support frame, the mixing barrel having a feed port and a discharge port, the support frame being externally fixed, the first motor being mounted on the support frame, the output shaft of the first motor being fixed with a first pulley and a second pulley; the stirring shaft and the stirring tube being coaxially arranged with the mixing barrel, the stirring shaft passing through the stirring tube, the stirring shaft being rotatably arranged relative to the stirring tube, the upper ends of the stirring shaft and the stirring tube being both located outside the mixing barrel, the upper end of the stirring tube being fixed with a third pulley, the upper end of the stirring tube being fixed with a fourth pulley, the first pulley and the third pulley being driven by a belt, the second pulley and the fourth pulley being driven by a belt, and the rotation speed of the stirring tube being greater than the rotation speed of the stirring shaft; the lower end of the stirring tube being fixed with a frame-type agitator located in the mixing barrel, the lower end of the stirring shaft being fixed with a stirring structure located in the middle area of ​​the frame-type agitator.

[0006] Through the above technical scheme, by setting up a stirring structure, which is located in the middle area of ​​the frame agitator, the material in the middle area of ​​the frame agitator can be stirred, and the stirring of the frame agitator itself can be coordinated to improve the mixing and stirring effect of the materials in the mixing barrel.

[0007] Furthermore, since the rotation speed of the frame agitator is greater than the rotation speed of the stirring structure, there is a speed difference between the two, which facilitates secondary stirring of the material, speeds up the flow of the material, and improves the stirring effect.

[0008] Optionally, the outer circumference of the stirring shaft is connected to the inner circumference of the stirring tube via a plurality of first bearings, a mounting cylinder is fixed to the support frame, the lower end of the mounting cylinder is fixed to the upper end of the mixing barrel, the mounting cylinder is sleeved on the stirring tube, and the outer circumference of the stirring tube is connected to the inner circumference of the mounting cylinder via a plurality of second bearings.

[0009] Through the above technical solution, by providing a mounting barrel, the coaxiality between the stirring shaft, the stirring tube and the mounting barrel is improved, thereby improving the rotational stability of the stirring shaft and the stirring tube.

[0010] Optionally, the stirring structure includes a plurality of groups of first blades, each group of first blades is arranged at intervals along the length direction of the stirring shaft, and a group of first blades includes a plurality of first blades evenly arranged around the circumference of the stirring shaft.

[0011] Optionally, it also includes a second motor, a first rotating shaft and multiple second rotating shafts, the stirring structure includes an inner mixing cylinder and multiple suction cylinders, the inner mixing cylinder is coaxially arranged with the mixing barrel, the upper end of the inner mixing cylinder is fixed to the lower end of the stirring shaft, the upper port of the inner mixing cylinder is lower than the liquid level of the mixing barrel, one end of the suction cylinder is connected to the outer wall of the inner mixing cylinder, the inner cavity of the suction cylinder is connected to the inner cavity of the inner mixing cylinder, multiple groups of suction cylinders are arranged at intervals along the axial direction of the inner mixing cylinder, and one group of suction cylinders includes multiple suction cylinders evenly arranged around the circumference of the inner mixing cylinder; the first rotating shaft passes through the inner mixing cylinder, and the first rotating shaft is coaxially rotatably connected to the inner mixing cylinder, and the second motor drives The first rotating shaft is driven to rotate, and the rotation direction of the first rotating shaft is opposite to the rotation direction of the inner mixing drum. The first rotating shaft is coaxially fixed with a first spiral piece, and the rotating first spiral piece is used to drive the material in the inner mixing drum to move downward and be discharged to the lower part of the inner cavity of the mixing barrel through the lower port of the inner mixing drum; the second rotating shaft passes through the suction cylinder, and the second rotating shaft is coaxially rotatably connected with the suction cylinder, the second rotating shaft is coaxially fixed with a second spiral piece, a second bevel gear is provided at one end of the second rotating shaft, the first spiral piece is fixed with a first bevel gear meshing with the second bevel gear, and the rotating second spiral piece is used to drive the material in the suction cylinder to move into the inner mixing cylinder.

[0012] Through the above technical scheme, the stirring shaft, the stirring tube and the first rotating shaft rotate at the same time, the stirring tube drives the frame agitator to rotate, the stirring shaft drives the inner mixing cylinder and the suction cylinder to rotate around the axis of the inner mixing cylinder, the first rotating shaft drives the first spiral piece to rotate, and through the cooperation of the first bevel gear and the second bevel gear, the second rotating shaft and the second spiral piece are driven to rotate around the axis of the suction cylinder. In this process, the rotating second spiral piece sucks the material near the barrel mouth of the suction cylinder into the suction cylinder, that is, the material near the inner wall of the mixing barrel will be sheared by the frame agitator and then sucked into the suction cylinder. At the same time, the rotating suction cylinder also stirs the material in the middle area of ​​the frame agitator, and the surrounding The upwardly moving suction cylinder can circumferentially absorb the material on the inner wall of the mixing barrel to reduce the dead angle of absorption. Secondly, the rotating second spiral piece moves the material in the suction cylinder into the inner mixing barrel, and the rotating first spiral piece is used to drive the material in the inner mixing barrel to move downward and discharge it to the lower part of the inner cavity of the mixing barrel through the lower port of the inner mixing barrel. After being discharged from the lower port of the inner mixing barrel, the material is sheared by the frame agitator again, and the material in the lower part of the mixing barrel is forced to move upward to the vicinity of the inner wall of the mixing barrel, and finally it is absorbed by the suction cylinder again to form a circular movement of the material, thereby greatly improving the flow speed, flow range and stirring frequency of the material, thereby improving the stirring effect.

[0013] In this way, by arranging the suction cylinder, the inner mixing cylinder, the first spiral sheet and the second spiral sheet, a circular movement of the material is formed. In one circular movement, the material will successively undergo the primary shearing of the frame agitator, the stirring and mixing of the rotating suction cylinder, the convergence and counter-mixing in the inner mixing cylinder, and the secondary shearing of the frame agitator, thereby greatly improving the flow speed, flow range, and stirring frequency of the material, thereby improving the stirring effect.

[0014] Optionally, the suction cylinder extends radially along the inner mixing cylinder, and one end of the suction cylinder is fixed to the outer wall of the inner mixing cylinder. A group of suction cylinders includes two suction cylinders, and a wing is fixed to the outer wall of the suction cylinder. The wing is inclined, and the inclination angles of the wing of two adjacent suction cylinders are opposite. The wing has a first curved surface and a second curved surface, wherein the area of ​​the first curved surface is larger than that of the second curved surface, and the first curved surface of one of the two suction cylinders in the same group is located on the upper surface of the wing, and the second curved surface is located on the lower surface of the wing, and the first curved surface of the other suction cylinder is located on the lower surface of the wing, and the second curved surface is located on the upper surface of the wing.

[0015] Through the above technical solution, when the suction cylinder rotates circumferentially around the inner mixing cylinder, due to the inclined setting of the winglets, the material is resisted by the inclined winglets when flowing along the second curved surface, and the material flows slowly to form a high-pressure area at the second curved surface. Since the area of ​​the first curved surface is larger than that of the second curved surface, the material flows along the first curved surface, and the material flows faster to form a low-pressure area. According to Bernoulli's principle, the fluid with a large flow rate has a smaller pressure, so the material in the high-pressure area will be offset and mixed to the low-pressure area. Moreover, since the inclination angles of the wings of two adjacent suction cylinders are opposite, and the first curved surface and the second curved surface of two adjacent wings are in opposite positions, the material will reciprocate along the axial direction to mix, thereby further improving the stirring effect.

[0016] Optionally, the first arcuate surface is convexly constructed with a plurality of first wedge blocks arranged at intervals along the length direction of the suction cylinder, the tip of the first wedge block faces the rotation direction of the suction cylinder, and the gap between two adjacent first wedge blocks is set as an acceleration zone; the second arcuate surface is convexly constructed with a plurality of second wedge blocks arranged at intervals along the length direction of the suction cylinder, the thick end of the first wedge block faces the rotation direction of the suction cylinder, and the gap between two adjacent second wedge blocks is set as a deceleration zone.

[0017] Through the above technical solution, when the material passes through the acceleration zone between the first wedge-shaped blocks, the material is squeezed by the side wall of the first wedge-shaped block, the material flow path is reduced, and the material flow rate of the first curved surface is accelerated; when the material passes through the deceleration zone between the second wedge-shaped blocks, the material flows in a diffuse manner, the material flow path is increased, and the material flow rate of the first curved surface is slowed down, thereby increasing the flow rate difference between the material on the first curved surface and the material on the second curved surface, thereby increasing the pressure difference, so as to further increase the reciprocating axial mixing speed and further improve the stirring effect.

[0018] Optionally, one end of the suction cylinder is fixed to the outer wall of the inner mixing cylinder, a rotating cylinder is sleeved on the outer side of the suction cylinder, the rotating cylinder is coaxially rotatably connected to the suction cylinder, a plurality of second blades are fixed to the outer wall of the rotating cylinder, a driven gear is coaxially fixed to the end of the rotating cylinder away from the inner mixing cylinder, the frame agitator is fixed with an annular driving surface gear, the annular driving surface gear is coaxially arranged with the inner mixing cylinder, and the annular driving surface gear is meshed with the driven gear.

[0019] Through the above technical scheme, since the rotation speed of the frame agitator and the rotation speed of the suction cylinder are different, it can be understood that the frame agitator rotates relative to the suction cylinder, so the torque of the frame agitator will be transmitted to the driven gear through the annular active surface gear to drive the rotating cylinder and the second blade to rotate around the axis of the suction cylinder. In this way, the second blade performs the first stirring of the material in the middle area of ​​the frame agitator, and the rotation of the suction cylinder around the inner mixing cylinder performs the second stirring of the material in the middle area of ​​the frame agitator. Under dual-direction stirring, the stirring effect can be greatly improved.

[0020] Optionally, one end of the suction cylinder is fixed to the outer wall of the inner mixing cylinder, a rotating cylinder is sleeved on the outer side of the suction cylinder, the rotating cylinder is coaxially rotatably connected to the suction cylinder, a third spiral sheet is coaxially fixed to the outer circumferential surface of the rotating cylinder, a driven gear is coaxially fixed to the end of the rotating cylinder away from the inner mixing cylinder, the frame agitator is fixed with an annular driving surface gear, the annular driving surface gear is coaxially arranged with the inner mixing cylinder, and the annular driving surface gear is meshed with the driven gear; the rotating third spiral sheet is used to push the material on the outside of the suction cylinder radially outward.

[0021] Through the above technical solution, since the rotation speed of the frame agitator and the rotation speed of the suction cylinder are different, it can be understood that the frame agitator rotates relative to the suction cylinder, so the torque of the frame agitator will be transmitted to the driven gear through the annular active surface gear to drive the rotating cylinder and the third spiral blade to rotate around the axis of the suction cylinder. In this way, the rotating third spiral blade will push the material on the outside of the suction cylinder radially outward, so that the material gathers at the mouth of the suction cylinder to be extracted by the second spiral blade, thereby reducing the situation where the material stagnates near the outer wall of the suction cylinder and cannot enter the flow circulation.

[0022] Optionally, the suction cylinders of two adjacent groups are arranged in a staggered manner along the circumference of the inner mixing cylinder, a third blade is fixed to the outer wall of the suction cylinder, one end of the suction cylinder is hingedly connected to the outer wall of the inner mixing cylinder, and the swing range of the suction cylinder is located in the radial plane of the inner mixing cylinder; a through hole is radially opened on the outer wall of the inner mixing cylinder, the inner cavity of the suction cylinder is connected with the inner cavity of the inner mixing cylinder through the through hole, the second bevel gear is rotatably matched with the inner wall of the through hole, a universal joint is provided in one end of the suction cylinder, and the two ends of the universal joint are respectively connected to the center of the second bevel gear and the second rotating The ends of the shaft are connected; the frame-type agitator is fixed with multiple groups of guide rings corresponding to each group of the suction cylinders, one group of guide rings includes two guide rings, the guide rings are coaxially arranged with the inner mixing cylinder, the guide rings are wavy along their own circumferences, and the guide rings are made of rubber; the frame-type agitator is fixed with a first arc rod and a second arc rod, the first arc rod is used to fix and shape the crest part of the guide ring, and the second arc rod is used to fix and shape the trough part of the guide ring, and the end of the suction cylinder away from the inner mixing cylinder is located in the gap between the two guide rings.

[0023] Through the above technical scheme, since the rotation speed of the frame agitator and the rotation speed of the suction cylinder are different, it can be understood that the frame agitator rotates relative to the suction cylinder, so the rotating guide ring will drive the suction cylinder to swing up and down along a wavy path, and combined with the rotation of the suction cylinder around the inner mixing cylinder, the wave-like swing of the suction cylinder is realized, and the torque of the first rotating shaft will be transmitted to the second rotating shaft and the second spiral sheet through the first bevel gear, the second bevel gear and the universal joint, so as to realize the absorption and driving of the material. In this way, the suction cylinder moving in the wavy path will increase the absorption range, thereby improving the mixing and stirring effect.

[0024] Furthermore, by increasing the rotation speed of the first motor, the difference between the rotation speed of the frame agitator and the rotation speed of the suction cylinder around the inner mixing cylinder can be increased, thereby increasing the up and down swinging frequency of the suction cylinder and shortening the distance between the crests and troughs of the suction cylinder on the swinging path, so that the dead angle of the swinging position of the suction cylinder relative to the mixing barrel is smaller and the suction is more complete.

[0025] Furthermore, by controlling the rotation speed of the first motor, the greater the difference between the rotation speed of the frame agitator and the rotation speed of the suction cylinder around the inner mixing cylinder, the greater the driving force of the guide ring on the suction cylinder, so as to increase the swing inertia of the suction cylinder, so that when the suction cylinder is located in the middle position between the crest and the trough of its own path, at this time, the guide ring is not constrained by the first arc rod and the second arc rod, the elastic deformation of the guide ring is maximum, and the guiding effect of the guide ring on the suction cylinder decreases. Therefore, the guide ring will buffer the swing inertia of the suction cylinder, so that the path of the suction cylinder is irregularly wavy, and the blind spot of its swing position relative to the mixing barrel is smaller.

[0026] At the same time, due to the irregular path of the suction cylinder, combined with the buffering of the guide ring and the application of its own elastic force, the instantaneous swing speed of the suction cylinder varies greatly, and the movement and stirring of the suction cylinder causes a large random disturbance to the material, thereby increasing the complexity of the material flow path and further improving the mixing and stirring effect.

[0027] The beneficial effects of this application are: 1. By setting a stirring structure, which is located in the middle area of ​​the frame agitator, the material in the middle area of ​​the frame agitator can be stirred, and the stirring effect of the material in the mixing barrel can be improved by cooperating with the stirring of the frame agitator itself; 2. By setting the suction cylinder, the inner mixing cylinder, the first spiral sheet and the second spiral sheet, the material is circulated and moved. In one circulation, the material will be sheared by the frame agitator, mixed and stirred by the rotating suction cylinder, mixed and mixed by the inner mixing cylinder, and sheared by the frame agitator. This greatly improves the flow speed, flow range and stirring frequency of the material, thereby improving the stirring effect. 3. By setting wings of different shapes to adjust the material flow rate on the upper and lower surfaces of the wings, a high-pressure area is formed at the second curved surface, and a low-pressure area is formed at the first curved surface. According to Bernoulli's principle, the fluid with a large flow rate has a smaller pressure, so the material in the high-pressure area will be offset and mixed to the low-pressure area. In addition, since the inclination angles of the wings of two adjacent suction cylinders are opposite, and the first curved surface and the second curved surface of two adjacent wings are in opposite positions, the material will reciprocate along the axial direction to mix, further improving the stirring effect.

The upper end of the first rotating shaft 15 passes through the first rotating sleeve 154, and the first rotating shaft 15 is rotatably connected to the first rotating sleeve 154, so that the first rotating shaft 15 can rotate relative to the inner mixing drum 12.

[0060] The lower end of the first rotating shaft 15 passes through the ring body 211 fixed by the frame agitator 21 and the bottom of the mixing barrel 10 in sequence, and a sealing ring (not shown in the figure) is provided at the part where the first rotating shaft 15 passes through the mixing barrel 10. The second motor 18 is externally fixed, and the output shaft of the second motor 18 is fixed to the lower end of the first rotating shaft 15. The second motor 18 is used to drive the first rotating shaft 15 to rotate, and the rotation direction of the first rotating shaft 15 is opposite to the rotation direction of the inner mixing barrel 12.

[0061] A first spiral blade 151 is coaxially fixed to the first rotating shaft 15 . The rotating first spiral blade 151 is used to drive the material in the inner mixing drum 12 to move downward and be discharged to the lower part of the inner cavity of the mixing barrel 10 through the lower port of the inner mixing drum 12 .

[0062] like Figure 4 As shown, the second rotating shaft 131 passes through the suction cylinder 13, and the second rotating shaft 131 is coaxially arranged with the suction cylinder 13. A third support rod 133 is fixed to the inner wall of the cylinder mouth of the suction cylinder 13, and a second rotating sleeve 134 is fixed to the third support rod 133. One end of the second rotating shaft 131 passes through the second rotating sleeve 134, and the second rotating shaft 131 is rotatably connected with the second rotating sleeve 134, so that the second rotating shaft 131 can rotate relative to the suction cylinder 13.

[0063] like Figure 3 , Figure 5 As shown, a second spiral sheet 132 is coaxially fixed to the second rotating shaft 131, and a second bevel gear 157 is fixed to one end of the second rotating shaft 131 through a fourth support rod 158. The second bevel gear 157 is located at the through hole 155. The second bevel gear 157 is coaxially arranged with the second rotating shaft 131, and the second bevel gear 157 is an annular structure to ensure the passage of materials.

[0064] An annular first bevel gear 156 is fixed to the outer side of the first spiral piece 151. The first bevel gear 156 is coaxial with the inner mixing drum 12. The inner wall of the inner mixing drum 12 is provided with an annular ring groove 150. The first bevel gear 156 is located in the ring groove 150, and the ring groove 150 is communicated with the through hole 155 to ensure that the first bevel gear 156 is meshed with the second bevel gear 157, so that the torque of the second motor 18 can be transmitted to the second rotating shaft 131 through the first rotating shaft 15, so that the second spiral piece 132 rotates. The rotating second spiral piece 132 is used to drive the material in the suction drum 13 to move into the inner mixing drum 12.

[0065] Furthermore, in order to improve the fixing strength of the first bevel gear 156 , the inner circumferential surface of the first bevel gear 156 may also be fixedly connected to the outer wall of the first rotating shaft 15 via a fifth support rod 159 .

[0066] During stirring, the first motor 108 and the second motor 18 are started at the same time, the stirring shaft 105, the stirring tube 106 and the first rotating shaft 15 rotate at the same time, the stirring tube 106 drives the frame stirrer 21 to rotate, the stirring shaft 105 drives the inner mixing drum 12 and the suction drum 13 to rotate around the axis of the inner mixing drum 12, the first rotating shaft 15 drives the first spiral piece 151 to rotate (the direction of rotation of the first spiral piece 151 is opposite to the direction of rotation of the inner mixing drum 12), and the torque of the first rotating shaft 15 is transmitted to the second rotating shaft 131 through the first bevel gear 156 and the second bevel gear 157 to drive the second rotating shaft 131 and the second spiral piece 132 to rotate around the axis of the suction drum 13. Therefore, in the process of the frame stirrer 21 rotating, the suction drum 13 rotating around the axis of the inner mixing drum 12, and the first spiral piece 151 and the second spiral piece 132 rotating, the rotating second spiral piece 132 sucks the material near the barrel mouth of the suction drum 13 into the suction drum 13 (the circulation flow direction of the material is shown in FIG. 1). Figure 3 The material in the mixing barrel 10 is sheared by the frame agitator 21 and then sucked into the suction cylinder 13. At the same time, the rotating suction cylinder 13 also stirs the material in the middle area of ​​the frame agitator 21. Moreover, the circumferentially moving suction cylinder 13 can perform circumferentially moving suction on the material on the inner wall of the mixing barrel 10 to reduce the suction dead angle. Secondly, the rotating second spiral blade 132 moves the material in the suction cylinder 13 into the inner mixing barrel 12, and the rotating first spiral blade 151 is used to drive the material in the inner mixing barrel 12 to move downward and discharge it to the lower part of the inner cavity of the mixing barrel 10 through the lower port of the inner mixing barrel 12. After being discharged from the lower port of the inner mixing barrel 12, the material is sheared by the frame agitator 21 again, and the material at the lower part of the mixing barrel 10 is forced to move upward to the vicinity of the inner wall of the mixing barrel 10, and finally is sucked by the suction cylinder 13 again to form a circular movement of the material, thereby greatly improving the flow speed, flow range, and stirring frequency of the material, thereby improving the stirring effect.

[0067] In summary, by setting the suction cylinder 13, the inner mixing cylinder 12, the first spiral sheet 151 and the second spiral sheet 132, a circular movement of the material is formed. In one circular movement, the material will successively undergo the primary shearing of the frame agitator 21, the stirring and mixing of the rotating suction cylinder 13, the convergence and counter-mixing in the inner mixing cylinder 12, and the secondary shearing of the frame agitator 21, thereby greatly improving the flow speed, flow range, and stirring frequency of the material, thereby improving the stirring effect.

[0068] Example 3 The difference between Example 3 and Example 2 is that Figure 6 , Figure 7 As shown ( Figure 6 and Figure 7 The direction of the hollow arrow in the figure is the flow direction of the material relative to the wing 16, and the solid arrow is the direction of the material flowing from the high pressure area to the low pressure area). The outer wall of the suction cylinder 13 is fixed with a wing 16, which is inclined, and the wing 16 of the two suction cylinders 13 in the same group has opposite inclination angles (the inclination directions of the two wing 16 can be seen). Figure 6 and Figure 7 ), the wing 16 has a first curved surface 161 and a second curved surface 162, wherein the area of ​​the first curved surface 161 is larger than that of the second curved surface 162, and the first curved surface 161 of one of the two suction tubes 13 in the same group is located on the upper surface of the wing 16, and the second curved surface 162 is located on the lower surface of the wing 16, and the first curved surface 161 of the other suction tube 13 is located on the lower surface of the wing 16, and the second curved surface 162 is located on the upper surface of the wing 16.

[0069] When the inner mixing cylinder 12 drives the suction cylinder 13 to rotate circumferentially, due to the inclined setting of the wing 16, the material is resisted by the inclined wing 16 when flowing along the second curved surface 162, and the flow speed of this part of the material is slower, so as to form a high-pressure area at the second curved surface 162. Since the area of ​​the first curved surface 161 is larger than the second curved surface 162, the material flows along the first curved surface 161, and the flow speed of this part of the material is faster to form a low-pressure area. According to Bernoulli's principle, the fluid with a large flow rate has a smaller pressure, so the material in the high-pressure area will be offset and mixed into the low-pressure area.

[0070] Furthermore, since the blades 16 of the two coaxial suction cylinders 13 have opposite inclination angles, and the first arcuate surfaces 161 and the second arcuate surfaces 162 of the two adjacent blades 16 are in opposite positions, when the two blades 16 of the same group stir the material in turn, they will drive the part of the material to reciprocate and mix along the axial direction of the inner mixing cylinder 12, thereby further improving the stirring effect.

[0071] Example 4 The difference between Example 4 and Example 3 is that Figure 8 , Fig. 9As shown ( Figure 8 and Fig. 9 The direction of the hollow arrow in the figure is the flow direction of the material, and the direction of the solid arrow is the circumferential movement direction of the wing 16 and the suction cylinder 13). The first arc surface 161 is protruded with a plurality of first wedge blocks 163, and the first wedge blocks 163 are arranged at intervals along the length direction of the suction cylinder 13. The tip of the first wedge block 163 faces the rotation direction of the suction cylinder 13, and the gap between two adjacent first wedge blocks 163 is set as an acceleration zone.

[0072] The second arc surface 162 is protruding with a plurality of second wedge blocks 164, and the second wedge blocks 164 are arranged at intervals along the length direction of the suction cylinder 13. The thick end of the first wedge block 163 faces the rotation direction of the suction cylinder 13, and the gap between two adjacent second wedge blocks 164 is set as a deceleration zone.

[0073] When the inner mixing cylinder 12 drives the suction cylinder 13 to rotate circumferentially, when the material passes through the acceleration zone between the first wedge-shaped blocks 163, the material is squeezed by the side wall of the first wedge-shaped blocks 163, and the material flow path is reduced, so that the material flow rate of the first arc surface 161 is accelerated; when the material passes through the deceleration zone between the second wedge-shaped blocks 164, the material flows in a diffuse manner, and the material flow path is increased, so that the material flow rate of the first arc surface 161 is slowed down, thereby increasing the flow rate difference between the material on the first arc surface 161 and the material on the second arc surface 162, thereby increasing the pressure difference, so as to further increase the reciprocating axial mixing speed and further improve the stirring effect.

[0074] Example 5 The difference between Example 5 and Example 2 is that Fig.10 , Fig.11 As shown, a rotating cylinder 135 is sleeved on the outer side of the suction cylinder 13, and the rotating cylinder 135 is coaxially rotatably connected with the suction cylinder 13. A plurality of second blades 137 are fixed to the outer wall of the rotating cylinder 135, and a driven gear 136 is coaxially fixed to one end of the rotating cylinder 135 away from the inner mixing cylinder 12.

[0075] The frame agitator 21 is welded with an annular driving face gear 22 , which is coaxially arranged with the inner mixing drum 12 , with the tooth surface of the driving face gear 22 facing upward, and the annular driving face gear 22 is meshed with the driven gear 136 .

[0076] Since the rotational speed of the frame agitator 21 is different from that of the suction cylinder 13, it can be understood that the frame agitator 21 rotates relative to the suction cylinder 13. Therefore, the torque of the frame agitator 21 will be transmitted to the driven gear 136 through the annular driving surface gear 22 to drive the rotating cylinder 135 and the second blade 137 to rotate around the axis of the suction cylinder 13. In this way, the second blade 137 performs the first stirring of the material in the middle area of ​​the frame agitator 21, and the circumferentially rotating suction cylinder 13 performs the second stirring of the material in the middle area of ​​the frame agitator 21. Under dual-directional stirring, the stirring effect can be greatly improved.

[0077] Example 6 The difference between Example 6 and Example 5 is that Fig.12 , Fig.13 As shown, a third spiral sheet 138 is coaxially fixed to the outer circumference of the rotating cylinder 135 .

[0078] The torque of the frame agitator 21 is transmitted to the driven gear 136 through the annular driving face gear 22, so as to drive the rotating cylinder 135 and the third spiral blade 138 to rotate around the axis of the suction cylinder 13. In this way, the rotating third spiral blade 138 pushes the material on the outside of the suction cylinder 13 radially outward, so that the material gathers at the mouth of the suction cylinder 13 to be extracted by the second spiral blade 132, thereby reducing the situation where the material stagnates near the outer wall of the suction cylinder 13 and cannot enter the flow circulation.

[0079] Example 7 The difference between Example 7 and Example 2 is that Fig.14 , Fig.15 , Fig.16 As shown, two adjacent groups of suction cylinders 13 are staggeredly arranged along the circumference of the inner mixing cylinder 12, a third blade 130 is fixed to the outer wall of the suction cylinder 13, one end of the suction cylinder 13 is hingedly connected to the outer wall of the inner mixing cylinder 12, specifically, a radially extending connecting cylinder 121 is fixed to the outer wall of the inner mixing cylinder 12, the connecting cylinder 121 is communicated with the inner cavity of the inner mixing cylinder 12 through a through hole 155, a first ear plate 123 is provided at the tube mouth of the connecting cylinder 121, a second ear plate 122 is fixed at the tube mouth of the suction cylinder 13, the first ear plate 123 and the second ear plate 122 are connected by a rotating pin 125, and the rotating pin 125 is horizontally arranged to ensure that the suction cylinder 13 can be hinged and swung up and down relative to the inner mixing cylinder 12, that is, the swing range of the suction cylinder 13 is located in the radial plane of the inner mixing cylinder 12.

[0080] Furthermore, in order to reduce the overflow of materials from the gap between the suction cylinder 13 and the connecting cylinder 121, the tube mouths of the suction cylinder 13 and the connecting cylinder 121 are jointly sleeved and fixed with a bellows 126, which is made of rubber and is bendable to adapt to the swing of the suction cylinder 13. Moreover, the inner wall of the bellows 126 has a blocking effect to ensure that the material in the suction cylinder 13 can enter the connecting cylinder 121 and the inner mixing cylinder 12 through the bellows 126.

[0081] The second bevel gear 157 is rotatably matched with the inner wall of the through hole 155. Specifically, an annular extension ring 173 is fixed to the inner wall of the through hole 155. The extension ring 173 is coaxially arranged with the through hole 155. The port of the extension ring 173 is inserted into the annular groove body 175 opened by the second bevel gear 157. Through this cooperation, the rotational connection of the second bevel gear 157 is realized, and the second bevel gear 157 is fixed with an insertion rod 171 through the sixth support rod 172. The insertion rod 171 is coaxial with the second bevel gear 157.

[0082] A universal joint 17 is provided at one end of the suction cylinder 13, one end of the universal joint 17 is coaxially fixed with the second rotating shaft 131, and a socket 176 is provided at the other end of the universal joint 17. The plug rod 171 is inserted into the socket 176, and the plug rod 171 can slide relative to the socket 176. The plug rod 171 is also provided with a key block 178, and a key groove 177 is provided on the inner wall of the socket 176. The key block 178 cooperates with the key groove 177 to ensure that the torque of the second bevel gear 157 can be transmitted to the second rotating shaft 131 through the sixth support rod 172, the plug rod 171, and the universal joint 17 in sequence, so as to ensure that the second spiral piece 132 therein keeps rotating during the swinging process of the suction cylinder 13.

[0083] like Fig.15 , Fig.17 As shown, the frame-type agitator 21 is fixed with multiple groups of guide rings 23 corresponding to each group of suction cylinders 13. One group of guide rings 23 includes two guide rings 23. The guide rings 23 are coaxially arranged with the inner mixing cylinder 12. The guide rings 23 are wavy along their own circumference. The guide rings 23 are made of rubber and have a circular cross-section.

[0084] The guide ring 23 is fixed in such a manner that a first arc rod 231 and a second arc rod 232 are welded and fixed to the inner side of the frame agitator 21 through a seventh support rod 233, and the cross-sections of the first arc rod 231 and the second arc rod 232 are C-shaped, and the outer surface of the crest part of the guide ring 23 is bonded to the inner side surface of the first arc rod 231, that is, the first arc rod 231 fixes and shapes the crest part of the guide ring 23; the outer surface of the trough part of the guide ring 23 is bonded to the inner side surface of the second arc rod 232, that is, the second arc rod 232 fixes and shapes the trough part of the guide ring 23, and the end of the suction cylinder 13 away from the inner mixing cylinder 12 is located in the gap between the two guide rings 23.

[0085] Since the rotational speed of the frame agitator 21 is different from that of the suction cylinder 13, it can be understood that the frame agitator 21 rotates relative to the suction cylinder 13. Therefore, the arc surface of the rotating guide ring 23 will force the suction cylinder 13 to swing up and down along a wavy path, and combined with the rotation of the suction cylinder 13 around the inner mixing cylinder 12, the circumferential wavy swing of the suction cylinder 13 is realized, thereby greatly expanding the suction range of the suction cylinder 13, thereby improving the mixing and stirring effect.

[0086] Furthermore, by increasing the rotation speed of the first motor 108, the difference between the rotation speed of the frame agitator 21 and the rotation speed of the suction cylinder 13 around the inner mixing cylinder 12 can be increased, thereby increasing the up and down swinging frequency of the suction cylinder 13 and shortening the distance between the crests and troughs of the suction cylinder 13 on the swinging path, so that the dead angle of the swinging position of the suction cylinder 13 relative to the mixing barrel 10 is smaller, and the suction dead angle is smaller.

[0087] Furthermore, by controlling the rotation speed of the first motor 108, the greater the difference between the rotation speed of the frame agitator 21 and the rotation speed of the suction cylinder 13 around the inner mixing cylinder 12, the greater the driving force of the guide ring 23 on the suction cylinder 13, so as to increase the swing inertia of the suction cylinder 13. Therefore, when the suction cylinder 13 is located in the middle position between the crest and the trough of its own path, at this time, the guide ring 23 is not constrained by the first arc rod 231 and the second arc rod 232, the elastic deformation of the guide ring 23 is maximum, and the guiding effect of the guide ring 23 on the suction cylinder 13 is reduced. Therefore, the guide ring 23 made of rubber material will buffer the swing inertia of the suction cylinder 13, so that the path of the suction cylinder 13 is irregularly wavy, and its swing position blind angle relative to the mixing barrel 10 is smaller.

[0088] At the same time, due to the irregular path of the suction cylinder 13, combined with the buffering of the guide ring 23 and the application of its own elastic force, the instantaneous swing speed of the suction cylinder 13 varies greatly, and the movement and stirring of the suction cylinder 13 has a large random disturbance to the material, thereby increasing the complexity of the material flow path and further improving the mixing and stirring effect.

[0089] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present application.
