Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0019] Please see Figure 1-5 This utility model provides a plate evaporator, including an evaporator body 1, an ultrasonic descaling device 2, and a lifting assembly 3; the ultrasonic descaling device 2 is installed on both sides of the evaporator body 1, and the ultrasonic descaling device 2 is distributed in a symmetrical position, and the ultrasonic descaling device 2 descals the evaporator body 1; the bottom ends of the evaporator body 1 are fixedly connected to the base brackets 4, and the lifting assembly 3 is installed on the inner side wall of the base brackets 4, and the lifting assembly 3 is located below the evaporator body 1, and the lifting assembly 3 is used to adjust the height of the evaporator body 1 in contact with the ground.

[0020] The evaporator body 1 serves as the core heat exchange carrier, enabling material evaporation and concentration. The ultrasonic descaling devices 2, installed on both sides of the body and symmetrically positioned above and below, remove scale buildup on the heat exchange surfaces inside the body through ultrasonic vibration. The base brackets 4 at both ends of the bottom of the evaporator body 1 provide support for the equipment. The lifting assembly 3, located on its inner side wall and below the body, adjusts the height of the evaporator body 1 relative to the ground or other objects to meet different installation and usage requirements.

[0021] Ultrasonic descaling avoids the cumbersome process, equipment corrosion, and material contamination associated with traditional manual and chemical descaling methods. It ensures heat exchange efficiency, reduces energy consumption and operating costs, and extends equipment lifespan. The lifting component breaks through the limitations of traditional fixed installation, flexibly adapting to the height requirements of different scenarios, reducing the need for additional support structures, lowering installation and commissioning costs, and improving equipment applicability.

[0022] The ultrasonic descaling device 2 includes a fixing component 21, which is installed on both sides of the evaporator body 1. An ultrasonic vibrating plate 22 is installed on the fixing component 21. An ultrasonic controller 23 is installed on one end surface of the evaporator body 1. The ultrasonic controller 23 is electrically connected to the ultrasonic vibrating plate 22.

[0023] The fixing assembly 21 stably installs the ultrasonic vibrating plate 22 on both sides of the evaporator body 1. The ultrasonic controller 23 (installed on one end surface of the body) is electrically connected to the ultrasonic vibrating plate 22. The controller outputs a control signal to drive the vibrating plate to generate ultrasonic vibration. The vibration is transmitted to the heat exchange area inside the evaporator body 1, causing the scale to detach from the heat exchange surface and realizing the descaling operation.

[0024] The combination of ultrasonic controller 23, ultrasonic vibrating plate 22, and fixing component 21 makes ultrasonic descaling more stable and controllable: the fixing component 21 ensures that the ultrasonic vibrating plate 22 is firmly installed, preventing displacement during vibration and affecting the descaling effect; the ultrasonic controller 23 can precisely adjust ultrasonic parameters to adapt to different scaling levels, improving the targeting and efficiency of descaling; compared with traditional descaling, no manual intervention is required throughout the process, reducing downtime, while avoiding damage to equipment and materials by chemical agents, ensuring production continuity and safety.

[0025] The ultrasonic vibrating plate 22 is positioned 5-8 mm away from the evaporator body 1. The ultrasonic vibrating plate 22 and the plate 104 of the evaporator body 1 are also positioned 5-8 mm apart. This distance allows the ultrasonic vibration generated by the ultrasonic vibrating plate 22 to be efficiently transmitted to the surface of the plate 104, ensuring that the vibration energy is fully applied to the scaling on the plate 104. It also avoids collision and wear caused by direct contact between the ultrasonic vibrating plate 22 and the plate 104, while reserving reasonable space for normal heat exchange of the plate 104, without affecting the flow of materials and heating medium.

[0026] The fixing component 21 includes a fixing frame 211, with a mounting hole 212 at the center of the fixing frame 211. An ultrasonic vibrating plate 22 is embedded in the mounting hole 212. Limiting plates 213 are integrally formed at both ends of the fixing frame 211. Both ends of the limiting plates 213 are attached to the evaporator body 1. The attachment points of the limiting plates 213 and the evaporator body 1 are connected by fasteners 214.

[0027] The mounting hole 212 in the center of the fixing bracket 211 is used to embed and fix the ultrasonic vibration plate 22. The limiting plates 213 integrally formed at both ends of the fixing bracket 211 are attached to the side wall of the evaporator body 1. The limiting plates 213 are fixed to the evaporator body 1 by fasteners 214 (such as bolts), thereby stably assembling the ultrasonic vibration plate 22 on the evaporator body 1, ensuring that the ultrasonic vibration plate 22 will not shift due to vibration during operation, and facilitating disassembly and maintenance in the future. To address the installation stability issue of the ultrasonic vibrating plate 22, the limiting plate 213 increases the contact area with the evaporator body 1, improving the reliability of the fixation. The fastener 214 facilitates the installation, disassembly, and replacement of the ultrasonic vibrating plate 22, reducing maintenance difficulty. The design of the fixing bracket 211 and the mounting hole 212 ensures the precise positioning of the ultrasonic vibrating plate 22, avoiding the impact of installation deviation on the descaling effect and improving the overall stability of the equipment.

[0028] The fixing component 21 also includes a slot 215 and a block 216. The slot 215 is formed on the side wall of the evaporator body 1, and the block 216 is fixed on the limiting plate 213 and corresponds to the position of the slot 215. The slot 215 is formed on the side wall of the evaporator body 1, and the block 216 corresponding to the position of the slot 215 is fixed on the limiting plate 213. When installing the fixing component 21, the block 216 is first embedded into the slot 215 to achieve initial positioning, and then the limiting plate 213 and the body are further fixed by the fastener 214, forming a double fixing structure of slot 215 positioning + fastener 214 fixing, ensuring that the fixing component 21 is installed accurately and firmly. The double fixing structure improves the installation accuracy and stability.

[0029] The cooperation between the slot 215 and the block 216 can quickly position the fixing component 21, reduce the positional deviation during installation, and improve assembly efficiency. At the same time, it avoids the loosening problem that may occur when relying solely on fasteners 214 for fixing. Especially under the long-term vibration of the ultrasonic vibrating plate 22, it can effectively prevent the fixing component 21 from shifting, ensure stable descaling effect, and reduce the risk of equipment failure.

[0030] The lifting assembly 3 includes two connecting plates 31. The two ends of the two connecting plates 31 are fixed to the inner side of the base frame 4 and are arranged in a symmetrical position. Threaded sleeves 32 are embedded at both ends of the surface of the connecting plates 31. A lead screw 33 is threadedly connected to the threaded sleeve 32. A support plate 34 is movably connected to the bottom of the lead screw 33. An adjusting block 35 is fixedly connected to the top of the lead screw 33.

[0031] Two connecting plates 31 are symmetrically fixed at both ends to the inner side of the base frame 4. The threaded sleeves 32 at both ends of the surface of the connecting plate 31 are threadedly connected to the lead screw 33. The support plate 34 at the bottom of the lead screw 33 is in contact with the ground or other objects. When the adjusting block 35 at the top of the lead screw 33 is rotated, the lead screw 33 moves up and down along the threaded sleeve 32, driving the support plate 34 to rise and fall, thereby changing the height of the connecting plate 31 and the base frame 4 and the evaporator body 1 connected to it, thus achieving height adjustment.

[0032] The mechanical adjustment structure is simple and reliable, and the height adjustment is flexible and controllable: fine-tuning of the height can be achieved by rotating the adjusting block 35, which is convenient to operate and requires no complex power equipment. Anti-slip grooves 5 are formed around the four sides of the surface of the adjusting block 35, and the distance between two adjacent anti-slip grooves 5 is equal.

[0033] The adjusting block 35 has equidistant anti-slip grooves 5 around its surface. When the adjusting block 35 is rotated to adjust the height, the anti-slip grooves 5 increase the friction between the hand or tool and the adjusting block 35, preventing slippage during operation and ensuring stable force can be applied to rotate the adjusting block 35. This allows for precise control of the lifting range of the lead screw 33, thus achieving precise adjustment of the height of the evaporator body 1.

[0034] The evaporator body 1 includes a fixed plate 101, a movable plate 102, and a support plate 103. Multiple sets of plates 104 are installed between the fixed plate 101 and the movable plate 102. The support plate 103 is located at one end near the movable plate 102. An upper guide rod 105 is provided at the top of the fixed plate 101, the movable plate 102, and the support plate 103. A lower guide rod 106 is provided at the bottom of the fixed plate 101, the movable plate 102, and the support plate 103. The fixed plate 101, the movable plate 102, and the support plate 103 are fixedly connected by bolts.

[0035] Multiple plates 104 are installed between the fixed plate 101 and the movable plate 102 to form a heat exchange channel between the material and the heating medium. The support plate 103 is located near the movable plate 102 and together with the fixed plate 101 and the movable plate 102, it forms the main frame. The upper guide rod 105 and the lower guide rod 106 pass through the top and bottom of the fixed plate 101, the movable plate 102, and the support plate 103, respectively, and play a guiding and positioning role for the three. Bolts fix the three together to ensure that the plates 104 fit tightly and avoid leakage of heat exchange medium or material. At the same time, it is convenient to remove the bolts to replace or clean the plates 104.

[0036] The mounting brackets 4 are fixed to the bottom of the fixed plate 101 and the support plate 103 respectively. The ultrasonic vibrating plate 22 is installed on both sides of the plate 104. The mounting brackets 4 are fixed to the bottom of the fixed plate 101 and the support plate 103 respectively, providing stable support for both ends of the evaporator body 1, and ensuring that the evaporator body 1 remains balanced during operation and height adjustment. The ultrasonic vibrating plate 22 is installed on both sides of the plate 104. The ultrasonic vibration generated by it can directly act on the surface of the plate 104, specifically removing the scale on the plate 104, and avoiding the scale from affecting the heat exchange efficiency of the plate 104.

[0037] The vibrating plates are installed directly on both sides of the plate 104, allowing ultrasonic energy to be precisely applied to the scaled areas for more thorough and efficient descaling. Compared to non-targeted installation, this further reduces the impact of scale on heat exchange efficiency, ensuring long-term efficient operation of the equipment. The surface array of the plate 104 features V-shaped flow channels 107, with a width of 8-12mm and a depth of 2-3mm.

[0038] The V-shaped flow channels arrayed on the surface of plate 104 can change the flow direction of the fluid when the material and heating medium flow through plate 104, increase the turbulence of the fluid on the surface of plate 104, prolong the fluid residence time, and improve the heat exchange efficiency between the material and the heating medium. At the same time, the width of 8-12mm and the depth of 2-3mm increase the contact area between plate 104 and the fluid while ensuring smooth fluid flow, further enhancing the heat exchange effect.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
