[0001] This utility model relates to the field of adhesive mixing technology, and in particular to an adhesive mixing reaction vessel. Background Technology

[0002] In a broad sense, a reaction vessel is a container that carries out physical or chemical reactions. Through structural design and parameter configuration, it achieves the heating, evaporation, cooling, and low-to-high-speed mixing functions required by the process. It is widely used in petroleum, chemical, rubber, pesticide, dye, pharmaceutical, and food industries. It is a pressure vessel used to complete processes such as hydrogenation, hydrocarbonation, polymerization, and condensation, such as reactors, decomposition tanks, and polymerization kettles. The materials generally include carbon manganese steel, stainless steel, zirconium, nickel-based alloys, and other composite materials. Adhesives are intermediates that connect two materials. They are mostly in the form of water-based agents and belong to the category of fine chemicals. There are many types of adhesives, and different adhesives require the use of corresponding reaction vessels for production.

[0003] In related technologies, Chinese utility model patent application number 202322165008.0 discloses a glue reaction vessel with sufficient convection, which discloses a technical solution that drives two flow-dividing arc plates to move linearly and reciprocally in the radial direction through a gear and rack transmission mechanism. However, the flow-dividing arc plates have the defect that the disturbance direction is unidirectional and the disturbance effect is poor for mixing multiple glue liquids. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a glue mixing reactor, which is beneficial for improving the turbulence effect on the glue and thus improving the production quality of the glue.

[0005] The adhesive mixing reactor of this utility model includes: a cylindrical body with a mixing chamber inside, the mixing chamber being connected to an inlet and an outlet; a stirring assembly including a reversible motor, a drive shaft, and a radial turbulence impeller, the reversible motor being connected to the upper end of the cylindrical body, one end of the drive shaft being connected to the output end of the reversible motor, the drive shaft passing through the mixing chamber, and the radial turbulence impeller including a plurality of first blades connected around the outer periphery of the drive shaft; and a flow-dividing assembly including a first connecting plate, a second connecting plate, and two flow-dividing plates, the first connecting plate and the second connecting plate being connected to opposite sides of the drive shaft and located on the same horizontal plane, the radial extension length of the first connecting plate being greater than the radial extension length of the second connecting plate, the two ends of the flow-dividing plates being arranged in the vertical direction, the two flow-dividing plates being connected to the upper ends of the first connecting plate and the second connecting plate, respectively, and the radial turbulence impeller being disposed between the two flow-dividing plates.

[0006] The adhesive mixing reactor according to the embodiments of this utility model has at least the following beneficial effects: A mixing chamber is provided inside the cylinder, and the adhesive to be mixed can be introduced into the mixing chamber from the inlet. A forward and reverse motor can drive the drive shaft to rotate in the forward or reverse direction. The drive shaft can drive the radial turbulence impeller and the flow-dividing assembly connected thereto to rotate. Specifically, the flow-dividing assembly includes a first connecting plate, a second connecting plate, and two flow-dividing plates. The first connecting plate and the second connecting plate are respectively connected to the opposite sides of the drive shaft and are located on the same horizontal plane. The upper ends of the two flow-dividing plates are respectively connected to the upper ends of the first connecting plate and the second connecting plate, and the radial turbulence impeller is disposed between the two flow-dividing plates. With the rotation of the drive shaft, the radial turbulence impeller can achieve radial turbulence of the adhesive. The mixing reactor turbulently directs some of the adhesive solution radially towards the flow divider assembly. The two flow dividers rotate with the drive shaft, thus turbulenting and agitating the adhesive solution near the cylinder wall. The radial extension length of the first connecting plate is greater than that of the second connecting plate, thereby offsetting the turbulent circumferences of the two flow dividers. The turbulent circumference of the flow divider connected to the first connecting plate is located outside the turbulent circumference of the flow divider connected to the second connecting plate, improving the flow divider assembly's effect on the adhesive solution. The mixed adhesive solution can then flow out of the mixing chamber from the outlet. In other words, the adhesive mixing reactor, through the cooperation of the stirring assembly and the flow divider assembly, improves the stirring and flow divider effect on the adhesive solution, achieving thorough mixing.

[0007] According to some embodiments of the present invention, the stirring assembly further includes an axial turbulence impeller, which is connected to the drive shaft and located between two flow dividers.

[0008] According to some embodiments of the present invention, the axial turbulence impeller is disposed above the radial turbulence impeller.

[0009] According to some embodiments of the present invention, the axial turbulence impeller includes a plurality of second blades arranged in a helical manner, the plurality of second blades being connected around the outer periphery of the drive shaft.

[0010] According to some embodiments of the present invention, it also includes a circulation pump and a circulation pipe, with both ends of the circulation pipe connected to the upper and lower ends of the cylinder respectively and both communicating with the mixing chamber, and the circulation pump connected to the circulation pipe.

[0011] According to some embodiments of the present invention, the diverter plate is arranged in an arc shape, and the diverter plate is provided with multiple through holes that penetrate radially along the drive shaft.

[0012] According to some embodiments of this utility model, the diameter of the through hole gradually decreases towards the end away from the drive shaft.

[0013] According to some embodiments of the present invention, the surface of the splitter plate facing away from the drive shaft is provided with multiple turbulence blocks.

[0014] According to some embodiments of the present invention, the stirring assembly further includes a bottom stirring block connected to the lower end of the drive shaft.

[0029] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0030] The existing reaction vessel has the defect of insufficient uniform mixing by the stirring mechanism, which can easily lead to substandard product quality and affect the processing quality of the adhesive.

[0031] Reference Figures 1-3 As shown, an embodiment of the adhesive mixing reactor of this utility model is suitable for the thorough mixing of two or more adhesives. The adhesive mixing reactor includes: a cylinder 100, a stirring assembly, and a flow distribution assembly 300.

[0032] Reference Figure 1 and Figure 2 As shown, the cylinder 100 is provided with a mixing chamber 110. The upper end and lower end of the mixing chamber 110 are respectively connected to an inlet 111 and an outlet 112. The adhesive liquid to be mixed can be introduced into the mixing chamber 110 from the inlet 111. The mixing chamber 110 can accommodate the stirring component and the flow distribution component 300 to achieve full mixing of two or more adhesive liquids. The fully mixed adhesive liquid can flow out from the outlet 112.

[0033] Reference Figure 1 and Figure 2As shown, specifically, the stirring assembly includes a first support, a reversible motor 210, a drive shaft 220, and a radial turbulence impeller 240. The first support is connected to the upper end of the cylinder 100, and the reversible motor 210 is connected to the first support, thereby achieving relative fixation between the reversible motor 210 and the cylinder 100. The output end of the reversible motor 210 is connected to the drive shaft 220 to drive the drive shaft 220 to rotate clockwise or counterclockwise in the up-down direction. Specifically, the radial turbulence impeller 240 includes multiple first blades 241. The length direction of the first blades 241 is consistent with the axial direction of the drive shaft 220, and the multiple first blades 241 are connected around the outer periphery of the drive shaft 220. The radial turbulence impeller 240 is connected to the drive shaft 220 and is mainly used to achieve radial turbulence of two or more adhesive liquids for turbulence and stirring.

[0034] Reference Figure 1 and Figure 2 As shown, specifically, the flow splitter assembly 300 includes a first connecting plate 310, a second connecting plate 320, and two flow splitters 330. The first connecting plate 310 and the second connecting plate 320 are straight strips. The first connecting plate 310 and the second connecting plate 320 are respectively connected to the opposite sides of the drive shaft 220. The first connecting plate 310 and the second connecting plate 320 are both located on the same horizontal plane and are both connected to the upper end of the drive shaft 220. The two ends of the flow splitter 330 are arranged in the vertical direction, that is, the length direction of the flow splitter 330 is consistent with the length direction of the drive shaft 220. The upper ends of the two flow splitters 330 are respectively connected to the upper ends of the first connecting plate 310 and the upper ends of the second connecting plate 320. The radial turbulence impeller 240 is located between the two flow splitters 330.

[0035] Reference Figure 1 and Figure 2 As shown, with the rotation of the drive shaft 220, the radial turbulence impeller 240 can achieve radial turbulence of the adhesive liquid, and cause part of the adhesive liquid to flow radially towards the diversion assembly 300. The two diversion plates 330 can rotate with the rotation of the drive shaft 220, thereby achieving turbulence and agitation of the adhesive liquid near the wall of the cylinder 100. The radial extension length of the first connecting plate 310 is greater than the radial extension length of the second connecting plate 320, thereby offsetting the turbulence circumference of the two diversion plates 330.

[0036] Reference Figure 2As shown in the figure, L1 represents the radial extension length of the first connecting plate 310, and L2 represents the radial extension length of the second connecting plate 320. Since the radial extension length of the first connecting plate 310 is greater than that of the second connecting plate 320, the flow divider 330 connected to the first connecting plate 310 is closer to the inner wall of the mixing chamber 110 than the flow divider 330 connected to the second connecting plate 320. This offsets the turbulence circumference of the two flow dividers 330, thereby improving the flow divider assembly 300's flow divider effect on the adhesive.

[0037] Reference Figure 1 and Figure 2 As shown, the turbulent circumferential surface of the diversion plate 330 connected to the first connecting plate 310 is located outside the turbulent circumferential surface of the diversion plate 330 connected to the second connecting plate 320. This can improve the diversion effect of the diversion component 300 on the adhesive liquid and increase the turbulence direction of the diversion component 300. The mixed adhesive liquid can flow out of the mixing chamber 110 from the outlet 112. That is, the adhesive liquid mixing reactor can improve the stirring and diversion effect of the adhesive liquid through the cooperation of the stirring component and the diversion component 300, so as to achieve full mixing of the adhesive liquid.

[0038] Reference Figure 1 and Figure 2 As shown, compared with traditional mixing reactors, the adhesive mixing reactor provided in this embodiment of the present invention can improve the stirring and diversion effect of the adhesive by combining the stirring component and the diversion component 300, so as to achieve full mixing of the adhesive.

[0039] Reference Figure 2 and Figure 3 As shown, it can be understood that the adhesive mixing reactor also includes an axial turbulence impeller 230, which is connected to the drive shaft 220 and located between two flow dividers 330. The axial turbulence impeller 230 includes a plurality of second blades 231 arranged in a spiral pattern, which are connected around the outer periphery of the drive shaft 220.

[0040] Reference Figure 2 and Figure 3 As shown, compared to the radial turbulence impeller 240 which is mainly used to achieve radial turbulence of two or more adhesives, the axial turbulence impeller 230 is mainly used to achieve axial turbulence of two or more adhesives. That is, the stirring assembly can achieve axial and radial turbulence and mixing of two or more adhesives to enhance the stirring effect of two or more adhesives.

[0041] Reference Figure 2 and Figure 3As shown, specifically, the axial turbulence impeller 230 is located above the radial turbulence impeller 240. When the forward and reverse motor 210 drives the drive shaft 220 to rotate, the drive shaft 220 can drive the axial turbulence impeller 230 to rotate, causing the adhesive to flow faster along the length of the drive shaft 220. This allows the adhesive to flow faster to the radial turbulence impeller 240, and the rotation of the radial turbulence impeller 240 enhances the mixing effect of two or more adhesives.

[0042] It should be understood that in some other embodiments, the first blade 241 of the radial turbulence impeller 240 is arranged in an arc shape. By rotating the radial turbulence impeller 240, the radial turbulence effect on the adhesive can be improved, so that the adhesive flows faster towards the radial plane, so that the adhesive flows faster to the diversion component 300. Under the stirring action of the diversion component 300, the diversion effect of the adhesive is improved.

[0043] Reference Figure 2 and Figure 3 As shown, it is understood that in this embodiment, considering that the adhesive deposited at the bottom of the mixing chamber 110 is difficult to be effectively stirred, the adhesive mixing reactor also includes a circulation pump 420 and a circulation pipe 410. The two ends of the circulation pipe 410 are respectively connected to the upper end and the lower end of the cylinder 100 and are both connected to the mixing chamber 110. The circulation pump 420 is connected to the circulation pipe 410.

[0044] Reference Figure 2 and Figure 3 As shown, specifically, the upper and lower ends of the cylinder 100 are respectively provided with a first circulation port and a second circulation port, both of which are connected to the mixing chamber 110. When the circulation pump 420 operates, it can, through pressure transformation, drive a portion of the adhesive solution out of the second circulation port and then through the circulation pipe 410 into the mixing chamber 110 from the first circulation port. That is, through the cooperation of the circulation pump 420 and the circulation pipe 410, the adhesive solution at the bottom of the mixing chamber 110 can circulate through the circulation pipe 410 into the upper layer of the mixing chamber 110, thereby ensuring thorough mixing of two or more adhesive solutions and improving the mixing uniformity of the two or more adhesive solutions.

[0045] Reference Figure 2 and Figure 3 As shown, it is understood that the stirring assembly further includes a bottom stirring block 250 connected to the lower end of the drive shaft 220. The bottom stirring block 250 includes a first sub-block 251 and a second sub-block 252. The first sub-block 251 includes a first turbulence section that is inclined from bottom to top in a direction away from the drive shaft 220, and the second sub-block 252 includes a second turbulence section that is inclined from bottom to top in a direction away from the drive shaft 220.

[0046] Reference Figure 2 and Figure 3As shown, as the drive shaft 220 rotates, the bottom turbulence block 332 located at the lower end of the drive shaft 220 also rotates. The bottom turbulence block 332 is mainly used to stir the adhesive at the bottom of the mixing chamber 110, which helps to reduce the mixing dead zone of the adhesive at the bottom of the mixing chamber 110. Furthermore, through the structural design of the bottom stirring block 250, the adhesive at the bottom can partially flow upward, thereby improving the mixing effect of two or more adhesives.

[0047] Reference Figure 2 and Figure 3 As shown, it can be understood that the flow divider 330 is arranged in an outwardly convex arc shape, and the flow divider 330 is provided with multiple channels that penetrate radially along the drive shaft 220. During the rotation of the flow divider 330, the flow divider 330 can not only mix two or more adhesives along the turbulence circumference, but also allow the adhesives to flow out through the through holes 331 on the flow divider 330. This means that the adhesives are first divided and then merged, which can effectively improve the mixing effect of two or more adhesives, so as to achieve full mixing of two or more adhesives.

[0048] Reference Figure 2 and Figure 3 As shown, specifically, the diameter of the through hole 331 gradually decreases towards the end away from the drive shaft 220. During the rotation of the flow divider plate 330, in conjunction with the radial acceleration of the adhesive by the radial turbulence impeller 240, some of the adhesive can pass through the through hole 331. Furthermore, the diameter setting of the through hole 331 allows the adhesive to pass through the through hole 331 at an accelerated speed, thereby enhancing the turbulence of two or more adhesives and improving the mixing effect of two or more adhesives, thus achieving full mixing of two or more adhesives.

[0049] It should be understood that in some other embodiments, when the flow divider 330 rotates with the drive shaft 220, the rotation trajectory of the flow divider 330 acts as a turbulent circumferential surface. In order to increase the flow rate of the adhesive through the through hole 331, the through direction of the through hole 331 is parallel to the tangential direction of the turbulent circumferential surface, so that during the rotation of the flow divider 330, more adhesive in contact with the flow divider 330 can pass through the through hole 331, thereby achieving the diversion and acceleration of the adhesive. By the diversion and re-merging of the adhesive, the mixing effect of multiple adhesives can be improved.

[0050] Reference Figure 2 and Figure 3 As shown, it can be understood that in this embodiment, the surface of the flow divider 330 facing away from the drive shaft 220 is provided with a plurality of turbulence blocks 332. As the drive shaft 220 rotates, the flow divider 330 can rotate in the forward or reverse direction. The plurality of turbulence blocks 332 located on the inner wall of the flow divider 330 facing the mixing chamber 110 can enhance the turbulence and flow divider effect of the flow divider assembly 300 on the adhesive liquid, thereby improving the mixing effect of two or more adhesive liquids.

[0051] Reference Figure 2 and Figure 3 As shown, multiple turbulence blocks 332 located on the same flow divider 330 have constricted ends that narrow away from the drive shaft 220, and the constricted ends of the multiple turbulence blocks 332 are not oriented in the same direction. For example, the constricted ends of some turbulence blocks 332 are arranged facing upwards, and the constricted ends of some turbulence blocks 332 are arranged facing downwards. This can effectively cause the adhesive liquid that is disturbed and diverted by the flow divider 330 to flow in different directions, thereby improving the diversion direction of the adhesive liquid and improving the mixing effect of two or more adhesive liquids.

[0052] Reference Figure 2 and Figure 3 As shown, it is understood that the adhesive mixing reactor has an observation window at the upper end of the cylinder 100, and the observation window is covered with an observation plate. The user can observe the mixing state of the adhesive in the mixing chamber 110 through the observation plate to help the user determine the mixing effect of two or more adhesives.

[0053] Reference Figure 2 and Figure 3 As shown, it is understood that the adhesive mixing reactor is equipped with valves at the inlet 111, outlet 112 and the first circulation port to control the opening and closing of the inlet 111, outlet 112 and the first circulation port, so that the mixing chamber 110 can form a relatively closed chamber to achieve full mixing of two or more adhesives.

[0054] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
