Description

Technical Field

[0001] This utility model application relates to the field of initiator preparation vessel technology, specifically to an initiator preparation vessel that facilitates reagent mixing. Background Technology

[0002] In the chemical production field, initiator preparation tanks are key equipment for achieving precise proportioning and stable storage of initiators, and are widely used in polymerization reactions, curing, and other processes. Traditional initiator preparation tanks typically employ methods such as stirring and mixing, heating, or cooling to control temperature and ensure the uniformity and activity of the initiator. However, existing initiator preparation tanks have certain shortcomings in practical applications. On the one hand, the mechanical movement of the stirrer and the continuous action of the external heating device during the preparation process can lead to localized temperature increases inside the tank. On the other hand, some initiators are extremely sensitive to temperature and are prone to decomposition reactions when heated inside the preparation tank. Once an initiator decomposes due to heat, it not only alters its chemical composition and the proportion of active ingredients, reducing initiation efficiency, but may also generate harmful byproducts, affecting the normal progress of subsequent chemical reactions, and even leading to problems such as substandard product quality and reduced production efficiency. Therefore, how to solve the problem of initiator decomposition due to heat in the preparation tank and ensure its effectiveness has become an urgent technical challenge.

[0003] Chinese Patent Publication No. CN215693427U discloses an initiator preparation tank for nitrile latex preparation. This tank has a spiral coil on its outer wall and a water bath at the outer end of the coil. Cold water is supplied to the spiral coil from a cold water tank to cool the tank, while hot water is supplied to the water bath to rapidly heat the tank, thus preventing excessive temperature inside the tank from causing initiator decomposition. However, when hot water is injected into the water bath, the hot water is unevenly distributed on the outer wall of the tank, easily leading to localized overheating and initiator decomposition. Therefore, this utility model application provides an initiator preparation tank that facilitates reagent mixing. Utility Model Content

[0004] To address the aforementioned issues, an initiator preparation tank that facilitates reagent mixing is provided. Through a linkage mechanism, the first and second guide plates are rotated, and dynamic adjustment avoids the flow resistance limitations of a fixed guide plate at a single angle. It can optimize the water flow path in real time according to temperature control requirements, resulting in a more uniform distribution of hot water in the water bath. This solves the problems of uneven hot water distribution and easy local overheating leading to initiator decomposition in traditional water baths.

[0005] To address the problems of existing technologies, this utility model application provides an initiator preparation tank that facilitates reagent mixing, comprising a water bath, a tank body coaxially disposed within the water bath, and further comprising a first flow guiding component, a second flow guiding component, and a linkage mechanism. The first flow guiding component is disposed on the inner wall of the water bath, and a first flow guiding plate in the first flow guiding component can oscillate axially around the inner wall of the water bath. The second flow guiding component is disposed on the outer wall of the tank body, and a second flow guiding plate in the second flow guiding component can oscillate axially around the outer wall of the tank body. The linkage mechanism connects the first flow guiding component and the second flow guiding component, and rotating the linkage mechanism can drive the first flow guiding component and the second flow guiding component to rotate in opposite directions.

[0006] Preferably, the first flow guiding component includes a first annular plate, a first gear ring, a plurality of first gears, and a plurality of first flow guiding plates. The first annular plate is disposed at the upper edge of the water bath tank. The first gear ring is rotatably disposed on the first annular plate. The plurality of first gears are evenly and rotatably distributed on the first annular plate. The first gears mesh with the first gear ring. The first flow guiding plates are linked to the first gears. Rotating the first gear ring can drive the first flow guiding plates to swing.

[0007] Preferably, the second flow guiding assembly includes a second annular plate, a second gear ring, a plurality of second gears, and a plurality of second flow guiding plates. The second annular plate is fitted onto the outer wall of the tank. The second gear ring is rotatably disposed on the second annular plate. The plurality of second gears are evenly and rotatably distributed on the second annular plate. The second gears mesh with the second gear ring. The second flow guiding plate is linked to the first gear. Rotating the second gear ring can drive the second flow guiding plate to swing.

[0008] Preferably, the second guide plate is disposed in the gap between two adjacent first guide plates.

[0009] Preferably, there is a first operating gap between the end of the first guide plate away from the inner wall of the water bath and the outer wall of the tank, and a second operating gap between the end of the second guide plate away from the outer wall of the tank and the inner wall of the water bath.

[0010] Preferably, the linkage mechanism includes a first connecting rod, a second connecting rod, and a rotating rod. The first connecting rod is vertically connected to the first gear ring, and the second connecting rod is vertically connected to the second gear ring. The bottom surfaces at both ends of the rotating rod are provided with sliding grooves. The upper ends of the first connecting rod and the second connecting rod are respectively movable and restricted in the sliding grooves. Rotating the rotating rod can drive the first connecting rod and the second connecting rod to rotate in opposite directions.

[0011] Preferably, the initiator preparation tank for easy reagent mixing further includes a cover plate and a limiting rod. The cover plate is disposed at the upper edge of the water bath. The cover plate is provided with a first through groove and a second through groove. The first through groove can accommodate the movement of the first connecting rod, and the second through groove can accommodate the movement of the second connecting rod. The limiting rod is vertically and rotatably disposed on the cover plate, and the upper end of the limiting rod is fixedly connected to the rotating rod.

[0012] Preferably, the initiator preparation vessel for easy reagent mixing further includes a spiral tube, which is densely packed at the top and sparsely packed at the bottom, surrounding the outer wall of the vessel.

[0013] The advantages of this utility model application compared to the prior art are:

[0014] By setting up the first and second flow guiding components, and by setting up multiple flow guiding plates, the hot water flow path in the water bath can be distributed around the outer wall of the tank. The hot water impacts several flow guiding plates and then flows through the gap between the flow guiding plates and the inner wall of the water bath or the outer wall of the tank. At the same time, the flow guiding plates can be rotated under the drive of the linkage mechanism to adjust the angle. Dynamic adjustment avoids the flow resistance limitation of fixed flow guiding plates at a single angle. The water flow path can be optimized in real time according to the temperature control requirements, so that the hot water distribution in the water bath is more uniform. Attached Figure Description

Detailed Implementation

[0023] To further understand the features, technical means, and specific objectives and functions achieved by this utility model application, the following detailed description of this utility model application is provided in conjunction with the accompanying drawings and specific embodiments.

[0024] like Figure 1-7 As shown, this utility model application provides an initiator preparation tank that facilitates reagent mixing, including a water bath 1, a tank body 2 coaxially arranged in the water bath 1, and a first flow guiding component 3, a second flow guiding component 4, and a linkage mechanism 5. The first flow guiding component 3 is disposed on the inner wall of the water bath 1, and the first flow guiding plate 33 in the first flow guiding component 3 can swing axially around the inner wall of the water bath 1. The second flow guiding component 4 is disposed on the outer wall of the tank body 2, and the second flow guiding plate 43 in the second flow guiding component 4 can swing axially around the outer wall of the tank body 2. The linkage mechanism 5 connects the first flow guiding component 3 and the second flow guiding component 4. Rotating the linkage mechanism 5 can drive the first flow guiding component 3 and the second flow guiding component 4 to rotate in opposite directions.

[0025] It should be noted that the water bath 1 has an inlet pipe and an outlet pipe that can be arranged opposite each other. The outlet pipe is close to the upper edge of the water bath 1, and the inlet pipe is close to the bottom of the water bath 1. Hot water is injected into the water bath 1 from the inlet, which can heat the tank 2. When reagents are added to the tank 2, the water bath 1 heats the tank 2, accelerating the reaction rate of the reagents in the tank 2. In order to make the hot water distribution in the water bath 1 more uniform, a first flow guiding component 3 and a second flow guiding component 4 are set. The arrangement of multiple flow guiding plates can make the hot water in the water bath 1 more uniform. The flow path is distributed around the outer wall of the tank 2. Hot water impacts several guide plates and then flows through the gap between the guide plates and the inner wall of the water bath 1 or the outer wall of the tank 2. At the same time, the guide plates can rotate under the drive of the linkage mechanism 5 to adjust the angle. Dynamic adjustment avoids the flow resistance limitation of the fixed guide plate at a single angle. The water flow path can be optimized in real time according to the temperature control requirements. When the guide plate is adjusted to coincide with the radial direction of the tank 2, the gap between the guide plate and the inner wall of the water bath 1 or the outer wall of the tank 2 is minimized, forcing the water flow to pass through the gap laterally, making the hot water diffusion more uniform.

[0026] The structural form of tank 2 is as follows: Figure 1-2As shown, a feed inlet is provided at the top and a discharge outlet is provided at the bottom of the tank 2. The discharge outlet can penetrate the bottom wall of the water bath 1. In order to further increase the contact area between the tank 2 and the hot water in the water bath 1, it is preferable to provide a groove at the bottom of the tank 2. The groove extends along the central axis of the bottom of the tank 2. The stirring mechanism inside the tank 2 can stir the material inside the tank 2.

[0027] The first flow guiding assembly 3 includes a first annular plate 30, a first gear ring 31, a plurality of first gears 32, and a plurality of first flow guiding plates 33. The first annular plate 30 is disposed along the upper edge of the water bath tank 1. The first gear ring 31 is rotatably disposed on the first annular plate 30. The plurality of first gears 32 are evenly and rotatably distributed on the first annular plate 30. The first gears 32 mesh with the first gear ring 31. The first flow guiding plates 33 are linked to the first gears 32. Rotating the first gear ring 31 can drive the first flow guiding plates 33 to swing. Figure 3-4 As shown, the first guide plate 33 assembly can drive the first guide plate 33 to swing within the water bath 1. Rotating the first guide plate 33 can change the size of the gap between the first guide plate 33 and the outer wall of the tank 2, thereby changing the flow path of hot water within the water bath 1. It should be noted that the first gear 32 meshes with the inner ring of the first gear ring 31.

[0028] The second flow guiding assembly 4 includes a second annular plate 40, a second gear ring 41, a plurality of second gears 42, and a plurality of second flow guiding plates 43. The second annular plate 40 is fitted onto the outer wall of the tank body 2. The second gear ring 41 is rotatably mounted on the second annular plate 40. The plurality of second gears 42 are evenly and rotatably distributed on the second annular plate 40, and the second gears 42 mesh with the second gear ring 41. The second flow guiding plates 43 are linked to the first gear 32. Rotating the second gear ring 41 can cause the second flow guiding plates 43 to swing. Figure 3 , Figure 5 As shown, the second flow guiding assembly 4 can drive the second flow guiding plate 43 to swing within the water bath 1. Rotating the second flow guiding plate 43 can change the size of the gap between the second flow guiding plate 43 and the inner wall of the water bath 1, thereby changing the flow path of hot water within the water bath 1. It should be noted that the second gear 42 meshes with the outer ring of the second gear ring 41.

[0029] The second guide plate 43 is disposed in the gap between two adjacent first guide plates 33. The spacing between the first guide plates 33 and the second guide plates 43 allows hot water to pass through the gap between the first guide plate 33 and the outer wall of the tank 2, or the gap between the second guide plate 43 and the inner wall of the water bath 1, and then through the gap between the second guide plate 43 and the inner wall of the water bath 1, or the gap between the first guide plate 33 and the outer wall of the tank 2. Extending the hot water flow path makes the hot water more evenly distributed in the water bath 1.

[0030] There is a first operating gap between the end of the first guide plate 33 away from the inner wall of the water bath 1 and the outer wall of the tank 2, and there is a second operating gap between the end of the second guide plate 43 away from the outer wall of the tank 2 and the inner wall of the water bath 1.

[0031] The linkage mechanism 5 includes a first connecting rod 50, a second connecting rod 51, and a rotating rod 52. The first connecting rod 50 is vertically connected to the first gear ring 31, and the second connecting rod 51 is vertically connected to the second gear ring 41. Slide grooves 520 are provided on the bottom surfaces of both ends of the rotating rod 52. The upper ends of the first connecting rod 50 and the second connecting rod 51 are movable and confined within the slide grooves 520. Rotating the rotating rod 52 can drive the first connecting rod 50 and the second connecting rod 51 to rotate in opposite directions. Figure 1 , Figure 2 and Figure 6 As shown, the operator can rotate the rotating rod 52 to drive the first connecting rod 50 and the second connecting rod 51 to move in opposite directions, thereby causing the first guide plate 33 and the second guide plate 43 to rotate counterclockwise or clockwise at the same time.

[0032] An initiator preparation vessel for easy reagent mixing also includes a cover plate 6 and a limiting rod. The cover plate 6 is disposed at the upper edge of the water bath 1. A first through groove 60 and a second through groove 61 are provided on the cover plate 6. The first through groove 60 can accommodate the movement of a first connecting rod 50, and the second through groove 61 can accommodate the movement of a second connecting rod 51. The limiting rod is vertically and rotatably disposed on the cover plate 6, and a rotating rod 52 is fixedly connected to the upper end of the limiting rod. Figure 1-2 As shown, the cover plate 6 can reduce heat loss in the water bath 1.

[0033] An initiator preparation vessel that facilitates reagent mixing also includes a spiral tube 7, which is densely packed at the top and sparsely packed at the bottom (not shown in the figure) and surrounds the outer wall of the vessel body 2. For example... Figure 7 As shown, the spiral tube 7 preferably has separate hot and cold water channels within its inner cavity. The inlet ends of the hot and cold water channels are connected to the hot water supply pipe and cold water supply pipe, respectively, via solenoid valves. The outlet ends are connected to the hot water return tank and cold water return pipe, respectively. The upper section with a denser pitch increases the upper heat exchange area, while the lower section with a looser pitch reduces the bottom water flow resistance. This, combined with the guide plate, forms a temperature gradient of hot at the top and cold at the bottom, meeting the requirement of maintaining the reaction temperature at the top and allowing solute to settle at the bottom during initiator preparation. A temperature sensor is installed inside the tank 2 to detect the temperature inside the tank 2. When the temperature inside the tank 2 is higher than the standard temperature, cold water is injected into the spiral tube 7 to lower the temperature inside the tank 2. When the temperature is lower than the standard temperature, hot water is injected into the spiral tube 7 to raise the temperature inside the tank 2. The baffle inside the spiral tube 7 forms an independent flow channel, and the hot and cold water flow directions are switched via solenoid valves, achieving temperature switching without emptying the pipeline.

It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model application, and these all fall within the protection scope of this utility model application. Therefore, the protection scope of this utility model application should be determined by the appended claims.
