Description

Technical Field

[0001] This utility model belongs to the technical field of evaporators, and in particular relates to a plate evaporator with zoned liquid distribution. Background Technology

[0002] The plate evaporator with zoned liquid distribution is a high-efficiency evaporation device that is an optimized upgrade of the traditional plate evaporator. Its core feature is that through a refined liquid distribution structure design, the heat exchange plate group of the evaporator is divided into different functional areas, and the liquid distribution is differentiated according to the heat exchange requirements and material state (such as concentration and viscosity) of each area. This solves the problems of uneven liquid distribution in traditional plate evaporators, such as local dry walls, low heat exchange efficiency, and material scaling.

[0003] However, it still has the following drawbacks in actual use: Most of the existing plate evaporators with zoned liquid distribution require multiple sets of plug-in shafts and fixing bolts for installation, which is quite cumbersome. At the same time, when tightening the bolts manually, the force of each set of fixing bolts is different, which makes the heat dissipation plate assembly unevenly stressed and prone to deformation or even damage. Utility Model Content

[0004] The purpose of this invention is to provide a plate evaporator with zoned liquid distribution. This invention solves the problem that in the existing solution, each plug shaft needs to be fixed with a bolt individually, which is a cumbersome process. At the same time, it is difficult to uniformly apply force to all support shafts when manually fixing the bolts, and uneven force at different points can easily cause the heat exchange plate assembly to deform or even be damaged.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a plate evaporator with regional liquid distribution, including a main component, a fixing component and an adjusting component. The main component includes a first fixing and pressing plate, one end of which is vertically fixed with a positioning rod, and the outer periphery of the positioning rod is movably connected to a heat exchange plate group and a second fixing and pressing plate. The fixing assembly includes an outer frame fixed to the end of the positioning rod away from the fixing pressure plate. A plug shaft is movably connected to the fixing pressure plate. A plug connector is fixed to one end of the plug shaft that extends into the inner cavity of the outer frame. A spring rod is fixed parallel to the inner cavity of the outer frame. A limiting member that matches the plug connector is fixed to the telescopic end of the spring rod. The outer frame is also threaded with a threaded rod at its center. The end of the threaded rod near the fixed clamping plate is rotatably connected to a contact plate. The contact plate is movably connected to the positioning rod, and the end of the threaded rod away from the contact plate is also fixed with a handle.

[0006] Furthermore, the contact surfaces of the connector and the limiting component are curved.

[0007] Furthermore, the associated plug shafts, plug parts, spring rods, and limiting parts are arranged in a group, with six groups arranged in an array, and three layers arranged in parallel and two columns arranged vertically.

[0008] Furthermore, the adjustment assembly includes a connecting plate, with two parallel limiting members on each layer fixed to the same connecting plate, a rack fixed to the opposite side of each connecting plate, and a gear meshing with the rack rotatably connected to the inner wall of the outer shell on the opposite side of the connecting plate.

[0009] Furthermore, the two racks meshing with the same gear are arranged in a centrally symmetrical manner.

[0010] Furthermore, the adjustment assembly also includes a second handle disposed on the outer surface of the outer frame, the second handle extending into the inner cavity of the outer frame and fixedly connected to one of the gears.

[0011] This utility model has the following beneficial effects: 1. This utility model, through its fixed assembly, allows for easy installation of the heat exchange plate assembly onto the positioning rod, followed by pushing the plug-in shaft into the outer casing. Rotating the handle causes the threaded rod to move axially along the threaded hole of the outer frame. The threaded rod pushes the contact plate along the positioning rod towards the fixed clamping plate, applying pressure to the fixed clamping plate and gradually reducing the distance between the fixed clamping plate until the heat exchange plate assembly is stably clamped. This solves the problem in existing solutions where each plug-in shaft requires individual bolt fixing, which is cumbersome. Furthermore, manual bolt fixing makes it difficult to apply uniform force to all support shafts, leading to uneven stress and potentially deformation or even damage to the heat exchange plate assembly.

[0012] 2. This utility model, through the setting of the adjustment component and the cooperation of multiple sets of gears and racks, enables the device to be disassembled by simply turning the handle two, which simultaneously drives all the limiting parts to disengage from the plug-in parts, thus realizing the disassembly of the device. This greatly improves the convenience of disassembly and solves the problem that the above-mentioned solution is still relatively cumbersome to adjust each set of limiting parts individually.

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0016] Please see Figure 1-5 As shown, this utility model is a plate evaporator with zoned liquid distribution, including a main component 1, a fixing component 2, and an adjusting component 3. The main component 1 includes a first fixing plate 11, one end of which is vertically fixed with a positioning rod 12. A heat exchange plate assembly 13 and a second fixing plate 14 are movably connected to the outer periphery of the positioning rod 12. The first fixing plate 11 and the second fixing plate 14 work together to form a clamping force on the heat exchange plate assembly 13, stably restricting the heat exchange plate assembly 13 between them, preventing the heat exchange plate assembly 13 from shifting position during evaporator operation, ensuring the stability of the internal structure of the evaporator, and facilitating subsequent zoned liquid distribution and heat exchange. The positioning rod 12, with one end vertically fixed to the first fixed clamping plate 11, provides a stable structural foundation and a track for the heat exchange plate assembly 13, the second fixed clamping plate 14, and the contact plate 27 to move stably. This ensures that these parts can move stably along the axial direction of the positioning rod 12, while precisely limiting the movement direction of each part to prevent lateral deviation and ensure the regularity of the overall structure. The heat exchange plate assembly 13 is the core component of the evaporator for heat exchange. Its surface can be divided into zones for liquid distribution. When the liquid flows on the surface of the heat exchange plate assembly 13, it transfers heat with the external heat source or cold source to complete the evaporation process. It is a key component for realizing the core function of the evaporator.

[0017] The fixing assembly 2 includes an outer frame 21 fixed to the end of the positioning rod 12 away from the fixing pressure plate 11. A plug shaft 22 is movably connected to the fixing pressure plate 11. A plug connector 23 is fixed to one end of the plug shaft 22 that extends into the inner cavity of the outer frame 21. A spring rod 24 is fixed parallel to the inner cavity of the outer frame 21. A limiting member 25 that matches the plug connector 23 is fixed to the telescopic end of the spring rod 24. A threaded rod 26 is also threaded to the center of the outer frame 21. A contact plate 27 is rotatably connected to one end of the threaded rod 26 near the fixing pressure plate 14. The contact plate 27 is movably connected to the positioning rod 12. A handle 28 is also fixed to the end of the threaded rod 26 away from the contact plate 27.

[0018] The outer frame 21 provides installation and housing space for components such as the plug-in shaft 22, plug-in piece 23, spring rod 24, limiting piece 25, and threaded rod 26 inside the fixing assembly 2, integrating these components into a single structure. It also provides some barrier against dust and impurities from the external environment, protecting the normal operation of the internal components. One end of the plug-in shaft 22 is movably connected to the fixed clamping plate 11, and the other end extends into the inner cavity of the outer frame 21 and is fixedly connected to the plug-in piece 23. It can move synchronously with the movement of the fixed clamping plate 11. Through cooperation with the limiting piece 25, it initially restricts the position of the fixed clamping plate 11, helping to maintain the stable clamping state of the heat exchange plate assembly 13. The contact surface between the plug-in piece 23 and the limiting piece 25 is an arc surface. This structural design facilitates the contact between the plug-in piece 23 and the limiting piece 25. The relative sliding and engagement between the positioning components 25, when the insertion shaft 22 drives the insertion component 23 to move, the limiting component 25, under the action of the spring rod 24, is in close contact with the insertion component 23, limiting the position of the insertion component 23, thereby restricting the movement range of the fixed pressure plate 11, ensuring the stability of the heat exchange plate assembly 13 clamping. One end of the spring rod 24 is fixed in the inner cavity of the outer frame 21, and the other end is fixedly connected to the limiting component 25, which has an elastic telescopic function. In the natural state, the spring rod 24 pushes the limiting component 25 and the insertion component 23 to fit tightly through its own elastic force, providing continuous pressure to the limiting component 25 and ensuring the limiting effect. When it is necessary to adjust the position of the fixed pressure plate 11, the spring rod 24 can extend and retract with the movement of the limiting component 25, providing buffer and restoring force for the movement of the parts.

[0019] The threaded rod 26 is threadedly connected to the center of the outer frame 21. One end is rotatably connected to the abutment plate 27, and the other end is fixed to the handle 28. When the handle 28 is rotated, the threaded rod 26 can be driven to move axially along the threaded hole of the outer frame 21, thereby pushing the abutment plate 27 to move along the positioning rod 12. After the abutment plate 27 contacts the fixed clamping plate 14, it can apply pressure to the fixed clamping plate 14, further adjusting the distance between the fixed clamping plate 11 and the fixed clamping plate 14, and enhancing the clamping force on the heat exchange plate assembly 13. At the same time, when it is necessary to disassemble or adjust the heat exchange plate assembly 13, the handle 28 can be rotated in the opposite direction to relax the pressure on the fixed clamping plate 14.

[0020] Furthermore, the contact surfaces of the connector 23 and the limiting member 25 are arc-shaped. The arc-shaped design can reduce wear when the two are in contact, extend the service life of the parts, and facilitate direct insertion without rotating the handle 234.

[0021] Furthermore, the associated plug-in shaft 22, plug-in component 23, spring rod 24, and limiting component 25 are arranged as a group, with six groups arranged in an array, and three layers arranged in parallel and two columns arranged vertically. The arrangement of multiple groups of fixing components can improve the stability of fixing and the uniformity of fixing pressure, and prevent excessive pressure in a certain place from causing the heat exchange plate group 13 to deform under stress.

[0022] Furthermore, the adjusting assembly 3 includes a connecting plate 31. Two parallel limiting members 25 in each layer are fixed to the same connecting plate 31. A rack 32 is fixed to the opposite face of each connecting plate 31. A gear 33, meshing with the rack 32, is rotatably connected to the inner wall of the outer shell on the opposite face of the connecting plate 31. The connecting plate 31 fixes the two parallel limiting members 25 in each layer into a single unit, allowing the two limiting members 25 in the same layer to move synchronously. A rack 32 is fixed to the opposite face of each connecting plate 31. The inner wall of the outer frame 21... The gear 33 is rotatably connected to the rack 32 and the two racks 32 meshing with the same gear 33 are arranged in a centrally symmetrical manner. When the gear 33 rotates, it can drive the two centrally symmetrical racks 32 to move in opposite directions through the meshing action with the rack 32. Then, through the connecting plate 31, it drives the two limiting members 25 on the same layer to move synchronously in opposite directions, thereby adjusting the position of the limiting members 25 and changing the cooperation state between the limiting members 25 and the plug-in member 23, so as to facilitate flexible adjustment of the position of the fixed pressing plate 11.

[0023] Furthermore, the two racks 32 meshing with the same gear 33 are arranged in a centrally symmetrical manner. Only a centrally symmetrical arrangement can drive the connecting plate 31 to move synchronously and at the same distance, or move close to each other, and ultimately drive the limiting member 25 and the plug member 23 to collide or separate from each other.

[0024] Furthermore, the adjustment component 3 also includes a second handle 34 disposed on the outer surface of the outer frame 21. One end of the second handle 34 extends into the inner cavity of the outer frame 21 and is fixedly connected to one of the gears 33, and the other end extends into the inner cavity of the outer frame 21 and is fixedly connected to one of the gears 33. When the second handle 34 is rotated, the gear 33 connected to it can be directly driven to rotate. Then, through the meshing transmission between the gear 33 and the rack 32, the connecting plate 31 and the limiting member 25 are driven to move, providing a convenient operating component for the operator to adjust the position of the limiting member 25 without the need for other tools, thus simplifying the operation process.

[0025] The specific working principle of this utility model is as follows: Before the evaporator is put into use, the state of the main component 1 needs to be adjusted by adjusting component 3 and fixing component 2 to ensure that the heat exchange plate group 13 is stable and in a suitable working position. The heat exchange plate group 13 can be installed on the positioning rod 12. Then, according to the actual thickness of the heat exchange plate group 13 and the installation requirements, the plug shaft 22 can be pushed into the outer shell. Rotate the handle 28 in the fixing component 2. The handle 28 drives the threaded rod 26 to move axially along the threaded hole of the outer frame 21. The threaded rod 26 pushes the abutment plate 27 to move along the positioning rod 12 towards the fixing pressure plate 14. After the abutment plate 27 contacts the fixing pressure plate 14, continue to rotate the handle 28 so that the abutment plate 27 applies pressure to the fixing pressure plate 14, pushing the fixing pressure plate 14 to move along the positioning rod 12 towards the fixing pressure plate 11, gradually reducing the distance between the fixing pressure plate 11 and the fixing pressure plate 14 until the two stabilize the heat exchange plate group 13.

[0026] After completing the above adjustments, the evaporator can enter normal working condition. The liquid is distributed in different areas on the surface of the heat exchange plate assembly 13 through the preset liquid distribution structure. When the liquid flows on the surface of the heat exchange plate assembly 13, it exchanges heat with the outside to complete the evaporation process. When it is necessary to disassemble the heat exchange plate assembly 13, turn the handle 28 in the opposite direction. The threaded rod 26 drives the contact plate 27 to move away from the fixed clamping plate 14, reducing the pressure on the fixed clamping plate 14. Then turn the handle 34 in the opposite direction. Through the transmission of the gear 33 and the rack 32, the limiting member 25 moves in the opposite direction, releasing the limitation on the plug-in member 23. At this time, the fixed clamping plate 11 and the fixed clamping plate 14 can be pushed to move in opposite directions to remove the heat exchange plate assembly 13.

[0027] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall be protected by the present utility model.
