Description

Technical Field

[0001] The present invention relates to the technical field of plate evaporators, in particular to an assembled plate evaporator and a rapid heat exchange structure thereof. Background Art

[0002] Heat exchange processes are widespread in industrial production and daily life. Evaporators, as key equipment for achieving this heat exchange, play a vital role in numerous fields, including refrigeration, chemical processing, and food processing. Plate evaporators are a widely used type of evaporator due to their high heat transfer efficiency, compact structure, small footprint, and ease of disassembly and cleaning.

[0003] In view of the above-mentioned related technologies, it was found that the traditional plate evaporator has some shortcomings in structural design and assembly methods. In terms of assembly, when installing the heat exchange plate group of the previous plate evaporator, the installation process between the movable pressure plate and the connecting baffle is relatively cumbersome. Due to the lack of an effective pre-pressing structure, when installing the long bolts connecting the movable pressure plate and the connecting baffle, it takes a lot of effort to adjust the position and spacing between the two, which not only increases the difficulty of installation, but also greatly reduces the installation efficiency. Moreover, during the installation process, the heat exchange plates are prone to mutual misalignment, which will cause uneven flow channels of cold and hot media between the heat exchange plates, affecting the uniformity and efficiency of heat transfer, and thus reducing the heat exchange performance of the entire evaporator.

[0004] In terms of structural stability, the frame design of traditional plate evaporators is not rational, resulting in inadequate support and positioning of the movable pressure plate and heat exchange plate assembly. The movable pressure plate does not slide smoothly on the frame, making accurate position adjustment difficult, which affects the assembly accuracy of the evaporator. Furthermore, the heat exchange plate assembly is prone to displacement during operation, resulting in reduced sealing performance and an increased risk of cold and hot medium leakage. This not only reduces evaporator reliability but also potentially damages the production environment and equipment. Summary of the Invention

[0005] In order to achieve the effects of flexible and accurate installation as well as convenient and safe use, the present application provides an assembled plate evaporator and a rapid heat exchange structure thereof.

[0006] The present invention is achieved in that:

[0007] An assembled plate evaporator and a rapid heat exchange structure thereof include an equipment frame, a movable pressure plate is installed on the equipment frame, and a connecting baffle is fixedly installed on the outer end of the equipment frame, the equipment frame includes a main frame frame and a sub-frame plate, the sub-frame plate is horizontally arranged at the lower end of the main frame frame, and the sub-frame plate is fixedly connected to the main frame frame, a heat exchange plate group is arranged between the movable pressure plate and the connecting baffle, and the two sides of the heat exchange plate group are respectively fitted and fixed with the movable pressure plate and the connecting baffle, a limited upper plate assembly is installed between the main frame frame and the upper end surface of the heat exchange plate group, and a limited lower plate assembly is installed between the sub-frame plate and the lower end surface of the heat exchange plate group.

[0008] By adopting this technical solution, the main frame and auxiliary frame structure of the equipment rack provide a stable support framework for the entire evaporator. A heat exchange plate assembly is installed between the movable pressure plate and the connecting baffle, and the heat exchange plate assembly is limited by the upper and lower limit plate assemblies. This ensures the stable installation of the heat exchange plate assembly, prevents displacement during installation and operation, and improves the overall stability and reliability of the evaporator.

[0009] Furthermore, the main frame includes a horizontal rod and a vertical rod frame. The vertical rod frame is vertically installed at one end of the horizontal rod, and the vertical rod frame and the horizontal rod are integrally formed. A connecting seat is also fixedly installed on the lower end surface of the vertical rod frame.

[0010] By adopting the above technical solution, the horizontal and vertical rods of the main frame are integrally formed, which enhances the structural strength of the main frame. The setting of the connecting seat facilitates the connection and fixation of the main frame to other components or the ground, further improving the stability of the equipment rack.

[0011] Furthermore, a positioning middle groove is opened in the middle of the vertical rod frame, and a flip bracket is installed in the positioning middle groove.

When in use, the rotating seat of the flip bracket can be rotated in the positioning middle slot to facilitate adjustment of the position of the auxiliary pressure plate. The provision of an operating head facilitates adjustment by better rotating the rotary holding screw with a tool, so that the auxiliary pressure plate can press the movable pressure plate or other components, playing an auxiliary fixing role and enhancing the tightness of the connection between the components. This makes it easier to connect the movable pressure plate and the connecting baffle with long bolts.

[0014] By adopting the above technical solution, the middle plate and the side plate of the movable pressure plate are connected by bolts, which is convenient for assembly and disassembly. After the long bolts are connected to the installation grooves on both sides of the movable pressure plate, the long bolts can be limited by the limiting pressure blocks on the side plates.

The lower end surface of the middle plate portion is provided with a positioning foot plate, and the positioning foot plate is formed integrally with the middle plate portion, and a matching groove corresponding to the limiting lower plate assembly is opened on the middle plate portion.

[0016] By adopting this technical solution, the guide frame of the middle plate slides with the horizontal rod, allowing the movable pressure plate to move smoothly along the horizontal rod, facilitating adjustment of the position between the movable pressure plate and the heat exchange plate assembly. The provision of the positioning foot plate and the matching groove improves the accuracy and stability of the movable pressure plate installation.

[0017] Furthermore, the connecting baffle includes a main board part, a device top plate and a second positioning foot plate. A cold medium inlet, a cold medium outlet, a hot medium inlet and a hot medium outlet are fixedly installed on the outer surface of the main board part.

The second positioning foot plate is installed on both sides of the lower end surface of the main board part, and the device top plate and the second positioning foot plate are both fixedly connected to the main board part.

[0018] By adopting this technical solution, the main plate of the connecting baffle is equipped with a cold medium inlet, cold medium outlet, hot medium inlet, and hot medium outlet, facilitating the entry and exit of cold and hot media, ensuring optimal heat exchange within the heat exchange plate assembly. The top plate of the equipment is conveniently connected to the horizontal rods. The second positioning foot plate is fixedly connected to the main plate, enhancing the structural strength of the connecting baffle and ensuring its installation stability.

[0019] Furthermore, the limiting upper plate assembly includes a double-headed slide rod, a movable seat plate and a support spring. The movable seat plate is symmetrically installed at both ends of the double-headed slide rod, and the movable seat plate is slidingly connected to the double-headed slide rod. The support spring is fixedly installed between the double-headed slide rod and the movable seat plate.

[0020] By adopting the above technical solution, the movable seat plate of the limiting upper plate assembly can slide on the double-headed slide rod, and the support spring provides elastic support. It can be adaptively adjusted according to the actual size of the heat exchange plate group to ensure effective limitation of the heat exchange plate group, and facilitate the synchronous adaptive changes when the movable pressure plate and the connecting baffle adjust the spacing.

[0021] Furthermore, the movable seat plate includes a top pressure plate, a limit strip and a guide shell for sliding installation of the double-headed sliding rod. The limit strip is evenly arranged on the lower end surface of the top pressure plate, and the guide shell is symmetrically installed on the upper end surface of the top pressure plate, and the top pressure plate, the limit strip and the guide shell are integrally formed.

[0022] By adopting this technical solution, the top pressure plate, limit bar, and guide shell of the movable seat plate are integrally formed, resulting in a simple structure and high strength. The limit bar cooperates with the positioning of the heat exchange plate assembly to further improve the positioning accuracy of the heat exchange plate assembly, effectively preventing installation misalignment and displacement of the heat exchange plate assembly during use. The guide shell ensures stable installation and use on the double-ended slide bar.

[0023] Furthermore, the limiting lower plate assembly includes a horizontal seat plate, a horizontal support rod and a reinforcement frame. The horizontal seat plate is fixedly installed on the lower end of the inner side of the main board part, the horizontal support rod is symmetrically installed on one side of the horizontal seat plate, and the horizontal support rod and the horizontal seat plate are integrally formed, and the reinforcement frame is fixedly installed on the lower end surface of the horizontal seat plate.

[0024] By adopting the above technical solution, by designing the limiting lower plate assembly into a structure that cooperates with a horizontal seat plate, a horizontal support rod and a reinforcement frame, a stable support and limitation is provided for the lower end of the heat exchange plate group during use. The reinforcement frame enhances the bearing capacity of the horizontal seat plate, ensuring the stable operation of the heat exchange plate group.

[0025] A rapid heat exchange structure for an assembled plate evaporator comprises a heat exchange plate group formed by a plurality of heat exchange plates bonded together, wherein the upper end surfaces of the heat exchange plates are provided with positioning grooves corresponding to limit bars.

[0026] By adopting the above technical solution, the heat exchange plate group is composed of several heat exchange plates bonded to each other, and the positioning grooves on the heat exchange plates correspond to the limit strips, which ensures the precise positioning of the heat exchange plates, thereby ensuring a stable sealing connection between the heat exchange plates, and preventing offset and misalignment, so that the cold and hot media can flow evenly between the heat exchange plates, thereby improving the heat transfer efficiency and achieving rapid heat exchange.

[0027] Compared with the prior art, the beneficial effects of the present invention are as follows: the present application installs a movable pressure plate by sliding on the equipment frame and a connecting baffle by fixedly installing on the equipment frame, so that after the heat exchange plate group is installed between the movable pressure plate and the connecting baffle, the movable pressure plate can be pre-pressed by first flipping the bracket on the equipment frame, thereby ensuring that the long bolts between the movable pressure plate and the connecting baffle are installed more easily. Through reasonable structural design and coordination between components, the evaporator can be quickly assembled and disassembled, and the installation and maintenance efficiency of the equipment is improved. At the same time, by installing the limiting upper plate assembly and the limiting lower plate assembly at the upper and lower ends of the equipment frame, it is convenient to better position the heat exchange plate group when installing, and the misalignment of the heat exchange plates can be effectively avoided. The stable connection and precise positioning between the components ensure the stable operation of the heat exchange plate group, improve the uniformity and efficiency of heat transfer, and thus improve the heat exchange performance and reliability of the entire evaporator.

[0050] The device provided in the embodiment of the present invention has the same implementation principle and technical effects as those in Example 1. For the sake of brief description, for matters not mentioned in this embodiment, reference may be made to the corresponding contents in Example 1.

[0051] Reference Figure 1 、 2 and Figure 3 As shown, a rapid heat exchange structure for an assembled plate evaporator includes a heat exchange plate group 4, which is composed of a plurality of heat exchange plates bonded together. Positioning grooves corresponding to the limiting strips 522 are defined on the upper end surfaces of the heat exchange plates. Heat exchange plate group 4 is composed of a plurality of heat exchange plates bonded together, and the positioning grooves on the heat exchange plates correspond to the limiting strips 522, ensuring precise positioning of the heat exchange plates and, in turn, a stable, sealed connection between the heat exchange plates, preventing misalignment and other problems. This allows for uniform flow of cold and hot media between the heat exchange plates, improving heat transfer efficiency and achieving rapid heat exchange.

[0052] Working principle: When assembling a plate-type evaporator, first install the equipment frame 1, and securely connect the main frame 11 and the auxiliary frame 12 together to ensure a secure connection. Secure the connecting seat 113 on the lower end face of the vertical rod frame 112 to the ground or other supporting structure. Sleeve the movable pressure plate 2 on the horizontal rod 111 of the main frame 11, so that the horizontal rod 111 slides with the guide frame 212 on the upper end face of the middle plate 21. Secure the top plate 32 of the equipment connecting the baffle 3 to one end of the horizontal rod 111 with bolts, and install the second positioning foot plate 33 on both sides of the lower end face of the main plate 31 to ensure that the connecting baffle 3 is securely installed. After the limiting upper plate assembly 5 and the limiting lower plate assembly 6 are installed on the equipment frame 1, the heat exchange plate group 4 can be installed between the movable pressure plate 2 and the connecting baffle 3. During installation, the heat exchange plates are fitted one by one, and the lower ends of the heat exchange plates are fitted on the sub-frame plate 12. Then, the upper ends of the heat exchange plates are clamped on the limiting strips 522 of the movable seat plate 52. After all the heat exchange plates are fitted, the flip bracket 13 is flipped to a horizontal position, and the holding screw 133 is rotated by the operating head 135 to make the auxiliary pressure plate 134 press the movable pressure plate 2, and then the heat exchange plate group 4 is stably pressed on the connecting baffle 3 through the movable pressure plate 2. Finally, the movable pressure plate 2 and the connecting baffle 3 are fixedly connected by long bolts.

[0053] In actual use, when the cold and hot media enter the heat exchange plate assembly 4 through the cold medium inlet and hot medium inlet connected to the baffle 3, respectively, the precise positioning and tight fit of the heat exchange plates form uniform flow channels between the cold and hot media. Heat is transferred through the heat exchange plates, achieving heat exchange between the cold and hot media. The upper and lower limit plate assemblies 5 and 6 ensure the stable operation of the heat exchange plate assembly 4, preventing displacement during operation, thereby improving the efficiency of heat transfer and achieving rapid heat exchange. After heat exchange, the cold and hot media flow out through the cold medium outlet and hot medium outlet, respectively.
