Description

Technical Field

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

[0002] Plate evaporators, as a commonly used high-efficiency heat exchanger in the industrial field, have been widely used in chemical reaction systems, food deep processing, and pharmaceutical purification processes due to their core advantages of compact structure and high heat transfer coefficient. Their core structure consists of multiple sets of corrugated metal plates stacked in an orderly manner. The plates are sealed by special sealing components, and then pressed and tightened by a rigid frame and high-strength clamping bolts to form independent and closed fluid channels. During operation, the material to be evaporated flows stably in the channels between the plates and efficiently transfers heat with the heating medium in the channel on the other side, quickly completing the evaporation heat exchange process and precisely adapting to the heat exchange efficiency and process stability requirements of various industries.

[0003] Plate heat exchangers are a type of high-efficiency indirect heat exchanger. Their core principle is to transfer heat between two fluids, cold and hot, through metal heat transfer plates. The core component is a corrugated metal heat transfer plate. Sealing gaskets at the edges of the plates divide the space between them into alternating flow channels, allowing the cold and hot fluids to flow in their respective channels. Heat is first transferred from the hot fluid to the hot side of the plate via convection, then conducted through the plate to the cold side, and finally transferred to the cold fluid via convection, completing the entire heat exchange process. The high efficiency stems from the corrugated plates increasing the heat transfer area and promoting turbulence in the fluids. Simultaneously, the cold and hot fluids often flow in opposite or cross-flow patterns, maximizing the average temperature difference, thus resulting in high heat exchange efficiency.

[0004] Plate heat exchangers are highly efficient heat exchange devices, with their core advantages being high heat exchange efficiency, compact structure, and convenient maintenance. They are assembled from multiple corrugated metal plates, and the flow channels formed between the plates allow the medium to flow in a turbulent state, increasing the heat exchange contact area and reducing thermal resistance. Furthermore, the detachable assembly structure simplifies maintenance; simply loosening the bolts allows for the removal of the plates for cleaning and replacement, significantly reducing maintenance costs. They are widely used in heat exchange scenarios with small to medium temperature differences and flow rates, such as in food processing and chemical industries, making them a preferred device that balances high efficiency and practicality. However, traditional manual tightening methods can lead to inconsistent sealing, resulting in leaks and excessive scale buildup that is difficult to clean. To address this, an evaporator has been proposed. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] Example:

[0041] An evaporator, reference Figure 1 and Figure 2 and Figure 4 The system includes a bridge 1, which serves as a connecting unit. A vibration mechanism 2 is fixedly connected to the outer wall of the bridge 1 to shake off scale and increase convenience. A retaining post 8 is installed below the bridge 1 to fix the internal equipment. A narrow plate 3 is fixedly connected to one side of the bridge 1 for support. A wide plate 4 is fixedly connected to the other side of the bridge 1 to fix the outlet and inlet. A discharge port 7 and a feed port 6 are fixedly connected to the outer wall of the wide plate 4 to provide a channel for materials. Multiple plates 9 are slidably connected to the outer wall of the retaining post 8 for heat exchange.

[0042] Specifically, bridge 1 serves as the core connection, ensuring the overall equipment functions as a single unit. The vibration mechanism 2 on the outer wall of bridge 1 reduces the difficulty of manually cleaning scale and increases convenience. The clamping column 8 below bridge 1 has the effect of fixing the internal equipment. The narrow plate 3 on one side of bridge 1 also serves as a support. The wide plate 4 on the other side of bridge 1 provides working space for the inlet and outlet. The discharge port 7 and inlet 6 on the outer wall of the wide plate 4 are the pipes for material flow. The multiple plates 9 on the outer wall of the clamping column 8 have the function of heat exchange.

[0043] The vibration mechanism 2 includes a drive block 21, which serves as the core power output. A disk 22 is fixedly connected to the drive end of the drive block 21 to transmit force. A connecting rod 24 is rotatably connected to one side of the disk 22, generating motion that drives subsequent equipment. A connecting rod 25 is rotatably connected to the other side of the connecting rod 24 for connection. A fixed seat 27 is rotatably connected to one end of the connecting rod 25 for both connection and fixation. A sliding column 29 is fixedly connected to one side of the locking column 8 to prevent the spring 28 from being thrown out. The outer wall of the sliding column 29 is fitted with the spring 28 to generate a reaction force. A sliding assembly 23 is fixedly connected to the outer wall of the disk 22. To ensure smooth operation of the equipment, the center seat 26 is fixedly connected to the outer wall of the bridge 1, and the connection point allows the connecting rod 25 to move in an arc. The outer wall of the locking column 8 is fixedly connected to the fixing seat 27, which serves to connect and fix. The locking column 8 and the sliding column 29 are slidably connected to the inner wall of the narrow plate 3, generating vibration to shake off the scale. The sliding component 23 includes a cylinder 231, which serves to connect. The cylinder 231 is fixedly connected to the disc 22, which serves to connect and transmit force. The inner wall of the narrow plate 3 is provided with a locking groove 232 and a limiting groove 233 to ensure smooth operation of the equipment. The outer wall of the locking column 8 is fixedly connected to the chassis 234, which serves to fix.

[0044] Specifically, the vibration mechanism 2 includes a drive block 21, which provides the power source for the entire mechanism and outputs driving force through its own operation. A disk 22 is connected to the drive end of the drive block 21, ensuring that the power of the drive block 21 is stably transmitted to the disk 22, causing the disk 22 to rotate synchronously with the drive block 21. A connecting rod 24 is connected to one side of the disk 22, allowing the connecting rod 24 to perform eccentric motion as the disk 22 rotates, converting the circular motion of the disk 22 into the initial power for reciprocating motion. On the other side, a connecting rod 25 is connected. The connecting rod 25 supports the reciprocating motion of the connecting rod 24, avoiding motion interference and ensuring continuous power transmission. One end of the connecting rod 25 is connected to a fixed seat 27, which provides a support point, making the connecting rod 25 move more flexibly and maintaining the stability of the power transmission direction. A sliding column 29 is fixedly connected to one side of the locking column 8, allowing the locking column 8 and the sliding column 29 to move synchronously. The sliding column 29 assists the locking column 8 in maintaining its sliding trajectory. A spring 28 is sleeved on the outer wall of the sliding column 29, which can buffer the sliding column 24. 9. The impact force during sliding is reduced, and the wear of parts is reduced. At the same time, the sliding column 29 is reset. The outer wall of the disc 22 is connected to the sliding component 23. The sliding component 23 rotates with the disc 22 to reduce friction and improve the smoothness of the disc 22's operation. The center seat 26 is connected to the outer wall of the bridge 1, so that the movement of the connecting rod 25 can drive the bridge 1 to vibrate, thus realizing the vibration effect on the bridge 1. The outer wall of the locking column 8 is connected to the fixing seat 27, which has the function of fixing and connecting. The locking column 8 and the sliding column 29 are connected to the inner wall of the narrow plate 3, so that the two slide along the narrow plate 3 in a directional manner, ensuring accurate movement trajectory and improving the operating accuracy of the mechanism. The sliding component 23 includes a cylinder 231, which has the function of connecting as a connection point. The cylinder 231 is fixedly connected to the disc 22, which has the function of connecting and transmitting force, driving the movement of other components. The inner wall of the narrow plate 3 is provided with a locking groove 232 and a limiting groove 233 to ensure the smooth operation of the equipment and extend the service life of the equipment. The outer wall of the locking column 8 is fixedly connected to the chassis 234, which has the function of fixing and increasing the stability of the equipment.

[0045] An evaporator, reference Figure 5 A pressure mechanism 5 is slidably connected to the outer wall of the locking post 8 to press the plate 9. The pressure mechanism 5 includes a support plate 51, which provides support. The support plate 51 is located below the locking post 8. A power block 52 is fixedly connected to the outer wall of the support plate 51. The power core outputs rotational force. A rotating shaft 53 is fixedly connected to the drive end of the power block 52, which transmits force and provides connection. A circular tooth 54 is fixedly connected to the outer wall of the rotating shaft 53, which is rotated along with it. A pressure plate 59 is fixedly connected to the outer wall of the support plate 51 to squeeze the internal equipment. A screw 57 is slidably connected to the inner wall of the pressure plate 59, which serves as the track for the movement of the pressure mechanism 5. A bolt 56 is threadedly connected to the outer wall of the screw 57 for fixing. A gear 55 is fixedly connected to the outer wall of the bolt 56, which meshes with the circular tooth 54. A screw 58 is threadedly connected to the outer wall of the support plate 51 to fix the power block 52.

[0046] Specifically, a pressure mechanism 5 is connected to the outer wall of the locking post 8, allowing the pressure mechanism 5 to adjust its position along the outer wall of the locking post 8 to adapt to different working scenarios, while ensuring stable relative movement between the two and avoiding deviation that could affect pressure transmission. The pressure mechanism 5 includes a support plate 51, which serves as the basic load-bearing component of the pressure mechanism 5, providing installation support for subsequent components and maintaining the overall structural integrity of the mechanism. The support plate 51 is located below the locking post 8, and a power block 52 is connected to the outer wall of the support plate 51 to ensure that the power block 52 moves synchronously with the support plate 51. The power block 52 can output driving force to provide a power source for the operation of the pressure mechanism 5. A rotating shaft 53 is connected to the drive end of the power block 52, so that the driving force of the power block 52 is stably transmitted to the rotating shaft 53, driving the rotating shaft 53 to rotate synchronously and avoiding power loss. A circular tooth 54 is connected to the outer wall of the rotating shaft 53 to ensure that the circular tooth 54 rotates synchronously when the rotating shaft 53 rotates. The circular tooth 54 can transmit power through a meshing structure to realize the conversion of power direction or torque. The support plate 51 is connected to a pressure plate 59 on its outer wall, which keeps the pressure plate 59 relatively fixed to the support plate 51. The pressure plate 59 can directly contact the target component and transmit pressure to the target component to achieve the clamping effect. The inner wall of the pressure plate 59 is slidably connected to a screw 57. The sliding connection allows the screw 57 to slide along the inner wall of the pressure plate 59, and the position of the screw 57 can be adjusted to adapt to different clamping requirements. At the same time, the radial displacement of the screw 57 is limited. The outer wall of the screw 57 is threadedly connected to a bolt 56. The axial position of the bolt 56 on the screw 57 can be adjusted by rotating the bolt 56, thereby adjusting the clamping force of the pressure plate 59. The threaded connection has self-locking properties to prevent loosening after clamping. The outer wall of the bolt 56 is connected to a gear 55, which rotates synchronously with the bolt 56. The gear 55 can receive power by meshing with an external transmission component to drive the bolt 56 to rotate, improving the convenience and accuracy of force adjustment. The screw 58 connected to the outer wall of the support plate 51 serves to fix the power block 52.

[0047] The implementation principle of this application embodiment is as follows: When it is necessary to vibrate and descale the plate 9, the drive block 21 set on the bridge 1 is activated. The drive block 21 outputs rotational force to drive the disc 22 to rotate. The disc 22 drives the connecting rod 24 to move through the cylinder 231. The connecting rod 24 pushes the connecting rod 25 to swing around the center seat 26 as the fulcrum. The other end of the connecting rod 25 drives the locking pin 8 to perform high-speed reciprocating linear motion under the guidance of the limiting groove 233 through the fixed seat 27, thereby causing the entire stack of plates 9 to generate high-frequency vibration. The scale attached to the surface of the plate 9 is peeled off due to the vibration. During the vibration, the sliding pin 29 slides stably in the slot 232. When the vibration stops, the elastic force of the spring 28 acts on the chassis 234, causing the locking pin 8 to automatically reset. This synergistic effect solves the problem of manual cleaning of scale in the prior art. The stable operation and convenience of the equipment are achieved through the vibration mechanism 2 and the sliding component 23.

[0048] When the evaporator needs to be clamped, the power block 52 installed on the support plate 51 is activated. The power block 52 is fixed by screws 58. Its output rotation force is transmitted to the circular gear 54 through the rotating shaft 53. The circular gear 54 drives the gear 55 that meshes with it to rotate. The gear 55 then drives the bolt 56 that is fixedly connected to it on the same axis to rotate. Since the bolt 56 and the screw 57 are threaded, the rotation of the bolt 56 will be converted into the linear pushing motion of the pressure plate 59 along the axis of the screw 57. Finally, uniform pressure is applied to the narrow plate 3 and the plate 9, pressing them towards the wide plate 4. The pressure mechanism 5 solves the problem of low efficiency of traditional manual clamping. The material is produced from the inlet 6 after heat exchange through the plate 9.

[0049] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
