Description
Technical Field
[0001] This utility model relates to the field of chemical equipment technology, specifically to a cylindrical structure with built-in turbulence-disrupting and baffle functions. Background Technology
[0002] In industrial production such as chemical, pharmaceutical, and food processing, reaction vessels, mixing tanks, or heat exchangers are core equipment, and their shell structure design directly affects production efficiency and product quality. In traditional jacketed reaction vessels, the heat transfer medium (such as chilled water or heat transfer oil) flowing within the jacket is prone to laminar flow or "short-circuiting" due to the large cross-section of the flow channel and lack of guidance. This means the fluid tends to follow the path of least resistance, resulting in insufficient heat exchange between the fluid and the shell wall, creating heat exchange dead zones within the jacket. This leads to uneven temperature distribution of the material inside the shell, affecting the reaction rate, mixing effect, and the uniformity and quality of the final product. To enhance heat exchange, existing technologies sometimes incorporate complex serpentine coils inside the shell. However, this not only significantly increases manufacturing costs and cleaning difficulty but may also occupy effective volume and adversely affect the flow field of the internal agitator.
[0003] Therefore, this utility model designs a cylindrical structure with built-in turbulence and baffle functions. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a cylindrical structure with built-in turbulence and baffle functions, which is compact, has high heat exchange efficiency, uniform temperature control, and strong practicality.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a cylindrical structure with built-in turbulence-inducing and baffle functions, comprising an outer jacket head, an inner cylinder head, an outer jacket cylinder, a staggered cylinder, guide plates, lugs, a grounding plate, a dished head, lifting lugs, a stirrer, a permanent magnet explosion-proof motor, a flange, and a flange cover. The outer jacket cylinder is coaxially arranged outside the staggered cylinder, forming a jacket space for the flow of the heat transfer medium. Multiple guide plates are arranged within the jacket space, distributed circumferentially along the cylinder, to force the heat transfer medium within the jacket to flow along a predetermined path and enhance turbulence. The bottom of the outer jacket cylinder is welded with an outer jacket end cap, and the bottom of the plum blossom bar cylinder is welded with an inner cylinder end cap. The outer jacket cylinder and the plum blossom bar cylinder together constitute the main cylinder. The lower side of the main cylinder is provided with a thermometer interface, and the upper side is provided with lugs and grounding plates for support and grounding. The top of the main cylinder is provided with a dished end cap. One side of the top of the dished end cap is provided with a lifting lug and multiple inlets, and the other side is provided with a manhole and a sight glass through a flange and a flange cover. The permanent magnet explosion-proof motor is fixed to the top of the dished end cap, and its output shaft is connected to the agitator. The agitator's agitator shaft passes through the central seal of the top of the dished end cap and extends into the interior of the main cylinder.
[0006] Preferably, both the outer jacket head and the inner cylinder head are spherical crown-shaped heads to provide good pressure resistance.
[0007] Preferably, the inlet includes, but is not limited to, a pressure equalization port, a feed port, a dripping port, a water inlet, a discharge port, a nitrogen port, and a pressure gauge interface.
[0008] Preferably, the bottom center of the main cylinder is provided with a discharge port, a chilled water outlet is provided on one side of the discharge port, and a chilled water inlet is provided on the upper side wall of the main cylinder, forming a heat transfer medium circulation channel within the jacket.
[0009] Preferably, the outer or inner wall surface of the plum blossom-shaped cylinder is provided with raised ribs or grooves, which increase the effective heat exchange area of the cylinder and enhance the turbulence of the fluid on both the inner and outer sides of the cylinder.
[0010] This utility model has the following beneficial effects:
[0011] 1. By cleverly setting the guide plate in the jacket space, the flow state of the heat transfer medium (such as chilled water) is forced to change from laminar flow to turbulent flow, and the fluid travel and disturbance are increased, which effectively destroys the fluid boundary layer, eliminates the heat exchange dead zone, and makes the heating or cooling of the cylinder wall more uniform and efficient.
[0012] 2. The turbulence and baffle functions are integrated into the outer jacket, eliminating the need for complex heat exchange coils inside the cylinder. This maintains a clean internal space, facilitates thorough material discharge and in-line cleaning (CIP) of the equipment, and reduces manufacturing costs and maintenance difficulty.
[0013] 3. Due to the improved overall temperature uniformity of the cylinder, the reaction or mixing process of the materials inside the cylinder is more precise and controllable, which is conducive to improving product quality and batch stability. Attached Figure Description

[0016] Figure 2 This is a top view of the present invention. Detailed Implementation
[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0018] Reference Figure 1-2This specific embodiment adopts the following technical solution: a cylindrical structure with built-in turbulence and baffle functions, including an outer jacket head 1, an inner cylinder head 2, an outer jacket cylinder 3, a staggered cylinder 4, a guide plate 5, an ear seat 6, a grounding plate 7, a dish-shaped head 8, a lifting lug 9, a stirrer 10, a permanent magnet explosion-proof motor 11, a flange 12, and a flange cover 13. The outer jacket cylinder 3 is coaxially arranged on the outside of the staggered cylinder 4, forming a jacket space for the flow of heat transfer medium; multiple guide plates 5 are arranged within the jacket space, distributed circumferentially along the cylinder, to force the heat transfer medium within the jacket to flow along a preset path and enhance turbulence. The bottom of the outer jacket cylinder 3 is welded with an outer jacket end cap 1, and the bottom of the plum blossom bar cylinder 4 is welded with an inner cylinder end cap 2. The outer jacket cylinder 3 and the plum blossom bar cylinder 4 together constitute the main cylinder. The lower side of the main cylinder is provided with a thermometer interface T1, and the upper side is provided with a lug 6 for support and grounding and a grounding plate 7. The top of the main cylinder is provided with a dished end cap 8. One side of the top of the dished end cap 8 is provided with a lifting lug 9 and multiple inlets 14, and the other side is provided with a manhole and a sight glass through a flange 12 and a flange cover 13. The permanent magnet explosion-proof motor 11 is fixed to the top of the dished end cap 8, and its output shaft is connected to the agitator 10. The agitator shaft of the agitator 10 passes through the central seal at the top of the dished end cap 8 and extends into the interior of the main cylinder.
[0019] It is worth noting that both the outer jacket head 1 and the inner cylinder head 2 are spherical crown-shaped heads to provide good pressure bearing capacity.
[0020] It is worth noting that the inlet 14 includes, but is not limited to, pressure equalization port N1, feed inlet N2, drip inlet N3, water inlet N4, discharge port N5, nitrogen port N6, and pressure gauge interface P.
[0021] It is worth noting that a discharge port N8 is provided at the bottom center of the main cylinder, a chilled water outlet N7a is provided on one side of the discharge port N8, and a chilled water inlet N7b is provided on the upper side wall of the main cylinder, forming a heat transfer medium circulation channel within the jacket.
[0022] In addition, the outer or inner wall surface of the plum blossom bar cylinder 4 is provided with raised ribs or grooves, which increase the effective heat exchange area of the cylinder and enhance the turbulence of the fluid on both the inner and outer sides of the cylinder.
[0023] The working principle of this specific embodiment is as follows: Multiple guide plates 5 are set in the jacket space. When the heat transfer medium (such as chilled water) enters the jacket from the chilled water inlet N7b, its flow path is blocked and guided by these guide plates. Forced turbulence: The guide plates force the fluid to constantly change direction and flow along a tortuous path. This forced path deflection and obstruction transforms the smooth laminar flow into violent turbulence (i.e., disturbance). Elimination of heat transfer dead zone: In turbulent flow, the particles of the heat transfer medium undergo irregular and chaotic motion, resulting in more thorough and frequent contact between the medium and the outer wall surface of the piezoelectric cylinder 4 (i.e., the inner cylinder). This greatly disrupts the heat transfer boundary layer, effectively eliminating the traditional heat transfer dead zone and achieving rapid and uniform heating or cooling of the entire cylinder. Formation of a complete cycle: After sufficient heat exchange, the medium finally flows out from the chilled water outlet N7a, completing a highly efficient heat exchange cycle. Inside the vessel, the working principle is similar to that of a conventional reactor, but it benefits from superior external temperature control: a permanent magnet explosion-proof motor 11 drives the stirrer 10 to rotate, mechanically agitating the materials entering the vessel through the feed inlet (N2, etc.). Due to the extremely high heat exchange efficiency of the external jacket, the temperature of the inner wall of the vessel is very uniform. This ensures that the temperature of the entire reaction system remains highly consistent when the stirrer is mixing materials, avoiding the impact on the reaction rate and product quality caused by localized overheating or undercooling.
[0024] This specific embodiment transforms the flow pattern of the heat transfer medium from inefficient laminar flow to efficient turbulent flow by installing a guide plate within the jacket, thereby achieving uniform and rapid temperature control of the cylinder. This precise external temperature control, combined with efficient internal mechanical stirring, provides a stable and uniform environment for chemical reactions or physical mixing processes within the cylinder, ultimately improving production efficiency and ensuring product quality.
[0025] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
