Description

Technical Field

[0001] This utility model relates to the field of ternary precursor technology, specifically to an auxiliary stirring device and a reaction vessel. Background Technology

[0002] To reduce the eddies generated by the stirring device in the reactor, baffles can be installed on the inner wall of the reactor, and eddy holes can be opened on the baffles to balance the pressure difference formed on both sides of the baffles.

[0003] For example, Chinese utility model patent CN201620528195.1, entitled "A Reactor for the Production of Environmentally Friendly and Energy-Saving Adhesives," includes a reactor body, a stirring mechanism, a feed inlet, and a discharge outlet. The reactor body includes support legs, a bottom, a cylindrical body, and a top cover. The stirring mechanism includes a speed-regulating motor, a stirring shaft, and a spiral stirring paddle. Three to eight elongated baffles, each 40 to 50 mm wide, are vertically installed on the inner wall of the cylindrical body. A row of vortex holes is evenly spaced along the vertical center line of each baffle. This device is simple in structure, easy to use, and highly practical. The baffles completely eliminate the swirling phenomenon of materials within the reactor, allowing the materials to move in different directions, achieving a uniform mixing effect through up-and-down tumbling. This further increases the dispersion of the materials and the probability of collisions between material molecules, resulting in a more complete reaction and a more significant stirring effect. It can generate good economic benefits and is easy to promote and use.

[0004] In actual production, the intensity of the vortex generated inside the vessel varies due to different stirring speeds. Since the size of the vortex holes on the baffle cannot be adjusted, it is not suitable for the vortices generated at different stirring speeds, resulting in uneven mixing of materials.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] To address the technical problem of uneven material mixing caused by the inability to adjust the size of the vortex holes on the baffle 200, making it unsuitable for vortices generated at different stirring speeds, this invention provides an auxiliary stirring device and a reaction vessel 100. The device enables the detection unit 300 to monitor the stirring speed of the stirring paddle 120 within the vessel body 110, and the adjustment component 400 to adjust the size of the through hole 210 relative to the baffle 200. This allows the vortex hole size to be adapted to the vortices generated at different stirring speeds, thereby eliminating the swirling phenomenon of materials within the vessel body 110 and improving the uniformity of material mixing.

[0027] Please see Figures 1 to 3 , Figure 1 , Figure 2 This is a schematic diagram of the auxiliary stirring device and the reaction vessel 100 in one embodiment of the present invention. The auxiliary stirring device is configured to connect to the reaction vessel 100. The reaction vessel 100 includes a vessel body 110 and a stirring paddle 120. The stirring paddle 120 is rotatably built into the reaction vessel 100. The auxiliary stirring device includes at least one baffle 200 and at least one adjusting component 400. The baffle 200 is connected to the circumferential inner wall of the vessel body 110 and has at least one through hole 210. The adjusting component 400 includes at least one adjusting member 410. The adjusting member 410 is disposed relative to the through hole 210 and connected to the baffle 200. The adjusting member 410 is movable relative to the baffle 200 to adjust the size of the through hole 210 being blocked.

[0028] In this device, compared with the prior art, by adjusting the movement of the component 400 relative to the baffle 200, the size of the through hole 210 that is blocked is adjusted so that the size of the formed vortex hole can be adapted to the vortex generated at different stirring speeds, thereby eliminating the swirling phenomenon of materials in the vessel body 110 and improving the uniformity of material mixing. This solves the technical problem in the prior art where the size of the vortex hole set on the baffle 200 cannot be adjusted, making it unsuitable for the vortex generated at different stirring speeds, thus resulting in uneven material mixing.

[0029] Furthermore, by setting a baffle 200 inside the reactor 100, the turbine inside the reactor can be reduced or eliminated, thereby eliminating the swirling phenomenon of materials inside the reactor body 110. For reference, please refer to Chinese Utility Model Patent No. CN211936894U entitled "An Air Blowing and Stirring Device for Reactor 100" and Chinese Utility Model Patent No. CN211706755U entitled "A Flow Control Device for Reactor 100". Further details will not be provided here.

[0030] In addition, in some embodiments, in order to further improve the uniformity of material mixing, a spiral-shaped stirring paddle 120 can be rotated. This is a conventional setting known to those skilled in the art and will not be described in detail here.

[0031] In this embodiment, the adjusting member 410 includes an adjusting plate 411, which is disposed relative to the through hole 210 and is slidably connected to the baffle 200 along the height direction of the vessel body 110, for adjusting the size of the through hole 210 that is blocked.

[0032] The adjusting plate 411 is configured relative to the through hole 210 to open or block the through hole 210. By sliding the adjusting plate 411 along the height direction of the vessel body 110, the area of ​​the adjusting plate 411 relative to the through hole 210 is adjusted, thereby adjusting the size of the through hole 210 that is blocked.

[0033] In one embodiment, please refer to Figure 1 The through hole 210 is oval in shape, and the length direction of the through hole 210 is the same as the height direction of the vessel body 110.

[0034] By setting a through hole 210 in the shape of an oval, and with the length direction of the through hole 210 being the same as the height direction of the vessel body 110, the adjustment range of the through hole 210 can be increased, thereby increasing the uniformity of material mixing.

[0035] In this embodiment, as Figure 2 As shown, the adjustment assembly 400 also includes two fixing bars 420. The two fixing bars 420 are spaced apart on both sides of the adjustment plate 411 and are both connected to the baffle 200. The opposite sides of the two fixing bars 420 are respectively provided with guide grooves, and the two side walls of the adjustment plate 411 are respectively slidably built into the guide grooves.

[0036] The fixing strip 420 is provided on both sides of the adjusting plate 411 and forms a guide groove for guiding the sliding of the adjusting plate 411, which plays a connecting and guiding role in the relative sliding between the adjusting plate 411 and the baffle 200.

[0037] Furthermore, the cross-section of the fixing strip 420 is "L" shaped, and the fixing strip 420 includes a first segment and a second segment arranged perpendicularly to each other. The first segment is parallel to and spaced apart from the baffle 200, and the two ends of the second segment are respectively connected to the baffle 200 and the first segment.

[0038] In one embodiment, please refer to Figure 2 , Figure 3The adjusting plate 411 has at least one spherical groove on the inner wall of the guide groove. The adjusting member 410 also includes at least one rolling part 412. The rolling part 412 is arranged in a one-to-one correspondence with the spherical groove. The rolling part 412 is rotatably built into the spherical groove and abuts against the inner wall of the guide groove.

[0039] By setting a spherical groove and a rolling part 412 that are designed to fit together, the frictional force when the adjusting plate 411 slides relative to the baffle 200 can be reduced, and the smoothness of the sliding of the adjusting plate 411 relative to the baffle 200 can be improved, thereby helping to improve the stability of the device operation.

[0040] Furthermore, the rolling part 412 here is a common and readily available steel ball or iron ball, which is a conventional setting known to those skilled in the art, and will not be described in detail here.

[0041] In one embodiment, please refer to Figure 3 Multiple spherical grooves are provided on both sides of the adjusting plate 411 facing away from each other.

[0042] Rolling parts 412 are provided between the contact surfaces of the adjusting plate 411 and the two fixing bars 420, which can cause the adjusting plate 411 to sway left and right when it slides along the guide groove, thereby improving the stability of the device during operation.

[0043] In this embodiment, the adjustment component 400 further includes a linear drive 430, which has a fixed end and a telescopic end. The fixed end of the linear drive 430 is connected to the baffle 200, and the telescopic end is connected to the adjustment plate 411, which is used to drive the adjustment plate 411 to slide relative to the baffle 200 along the height direction of the vessel body 110.

[0044] The fixed end and telescopic end of the linear drive 430 are connected to the baffle 200 and the adjusting plate 411 respectively. The movement of the telescopic end of the linear drive 430 relative to its fixed end allows the adjusting plate 411 to slide along the guide groove of the wire, thereby driving the adjusting plate 411.

[0045] Furthermore, the linear drive component 430 here is a commonly available and readily procurable push rod motor, hydraulic cylinder, or pneumatic cylinder. The linear drive component 430 is located near the top of the vessel body 110 and has a waterproof effect, making it suitable for use in the vessel's internal environment. This is a conventional configuration known to those skilled in the art and will not be described in detail here.

[0046] In this embodiment, as Figure 1 As shown, the auxiliary stirring device also includes a detection unit 300, which is connected to the vessel body 110 and is used to detect the stirring speed of the stirring paddle 120. The detection unit 300 is also electrically connected to the linear drive component 430.

[0047] In some embodiments, the detection unit 300 in this device is electrically connected to the linear drive 430 through a PLC controller. The stirring speed detected by the detection unit 300 can control the action of the linear drive 430, thereby controlling the size of the through hole 210.

[0048] Furthermore, the detection unit 300 here is a flow rate sensor that is common and readily available on the market, capable of detecting the stirring speed of the mixture in the vessel 110. The PLC controller is a common and readily available device on the market, which is a conventional setting known to those skilled in the art, and will not be described in detail here.

[0049] In this embodiment, as Figure 1 , Figure 2 As shown, the baffle 200 has multiple through holes 210, which are spaced apart along the length of the baffle 200. The number of adjusting plates 411 corresponds to the number of through holes 210. The adjusting assembly 400 also includes multiple connecting rods 440, which are arranged in pairs. A pair of connecting rods 440 are parallel to each other and spaced apart between two adjacent adjusting plates 411. The two ends of the connecting rods 440 are respectively connected to two adjacent adjusting plates 411.

[0050] Multiple through holes 210 are provided at intervals on the baffle 200, which can effectively eliminate the swirling phenomenon of materials in the vessel 110, allowing the materials to move in different directions, achieving a uniform mixing effect by tumbling the materials up and down, further increasing the dispersion of materials and the probability of collision between material molecules, making the reaction of materials more complete and the stirring effect more significant.

[0051] Furthermore, the adjusting plate 411 is provided in a one-to-one correspondence with the through hole 210, and two adjacent adjusting plates 411 are connected by a connecting rod 440 to form a whole, so that the telescopic end of the linear drive member 430 can simultaneously drive multiple adjusting plates 411 to slide relative to the baffle 200.

[0052] Furthermore, the two connecting rods 440 form a group, and the two connecting rods 440 are parallel to each other and spaced apart between two adjacent adjusting plates 411 to increase the stability of the connection and improve the stability of the device during operation.

[0053] In this embodiment, as Figure 1 As shown, there are multiple baffles 200, which are spaced apart along the circumferential inner wall of the vessel body 110 and are respectively connected to the circumferential inner wall of the vessel body 110.

[0054] By setting multiple baffles 200 at intervals along the circumferential inner wall of the vessel 110, the swirling phenomenon of materials inside the vessel 110 can be effectively eliminated, allowing the materials to move in different directions and achieve a uniform mixing effect by tumbling up and down. This further increases the dispersion of materials and the probability of collisions between material molecules, making the reaction of materials more complete and the stirring effect more significant.

[0055] This utility model also provides a reaction vessel 100, including a vessel body 110, a stirring paddle 120 and the above-mentioned auxiliary stirring device. The interior of the vessel body 110 is hollow. The stirring paddle 120 is rotatably built into the vessel body 110 and connected to the vessel body 110. The baffle 200 is spaced apart from the stirring paddle 120 and connected to the circumferential inner wall of the vessel body 110.

[0056] Furthermore, the vessel body 110 here is a common and readily available sealed tank on the market. The reactor 100 should also include a stirring motor and a feeding structure for adding materials, water, and solutions. The stirring motor and the feeding structure are both connected to the vessel body 110. This is a conventional setting known to those skilled in the art and will not be described in detail here.

[0057] To better understand this utility model, the following is combined with... Figures 1 to 3 The technical solution of this utility model is described in detail below:

[0058] The auxiliary stirring device includes at least one baffle 200 and at least one adjusting component 400. The baffle 200 is connected to the circumferential inner wall of the vessel body 110 and has at least one through hole 210. The adjusting component 400 is movable relative to the baffle 200 to adjust the size of the through hole 210. Compared with the prior art, by adjusting the size of the through hole 210 relative to the baffle 200, the size of the vortex hole can be adapted to the vortex generated at different stirring speeds, thereby eliminating the swirling phenomenon of materials inside the vessel body 110 and improving the uniformity of material mixing.

[0059] In the specific working process of this utility model, the stirring speed of the stirring paddle 120 inside the vessel 110 is first detected by the detection unit 300. The automatic control system identifies whether the size of the through hole 210 needs to be adjusted. Then, the linear drive component 430 drives the adjusting plate 411 to slide relative to the baffle 200 to adjust the size of the through hole 210 that is blocked. This ensures that the size of the formed vortex hole is suitable for the vortices generated at different stirring speeds, thereby eliminating the swirling phenomenon of materials inside the vessel 110 and causing the materials to move in different directions. This achieves a uniform mixing effect by tumbling the materials up and down, further increasing the dispersion of the materials and the probability of collisions between material molecules, making the reaction of the materials more complete and the stirring effect more significant.

[0060] This application, through the above structure, can solve the technical problem in the prior art where the size of the vortex holes provided on the baffle 200 cannot be adjusted, making it unsuitable for vortices generated at different stirring speeds, thus resulting in uneven material mixing.

[0061] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
