Description

Technical Field

[0001] This utility model belongs to the technical field of chemical evaporation equipment, and in particular relates to an axially adjustable silicon carbide tube thin film evaporation device. Background Technology

[0002] Thin-film evaporation equipment is a highly efficient heat transfer, evaporation, concentration, or separation device, mainly used in industries such as chemical, pharmaceutical, and food processing to handle heat-sensitive, high-viscosity, or easily coking liquid materials.

[0003] The tubes inside the thin-film evaporators commonly used in the market are of fixed length, and the effective evaporation length of the tubes cannot be dynamically adjusted. When processing high-viscosity materials, they are prone to blockage due to high flow resistance, while low-viscosity materials are inefficient due to insufficient evaporation path, which seriously affects continuous production and results in low equipment efficiency and narrow application range. Utility Model Content

[0004] The purpose of this invention is to provide an axially adjustable silicon carbide tube thin film evaporation device to solve the problems existing in the prior art.

[0005] To achieve the above objectives, the present invention employs an axially adjustable silicon carbide tube thin-film evaporation device, comprising an upper tube sheet, an upper silicon carbide tube installed below the upper tube sheet via a flange, a lower silicon carbide tube passing through a clamping plate assembly, the lower silicon carbide tube slidably disposed inside the upper silicon carbide tube, and one end of the lower silicon carbide tube away from the upper silicon carbide tube disposed on the lower tube sheet, a lower ring sleeve disposed around the lower tube sheet, and an electric cylinder disposed inside the lower ring sleeve, the output end of the electric cylinder being connected to the clamping plate assembly, the electric cylinder being able to drive the clamping plate assembly to move up and down, and the upper and lower silicon carbide tubes being adjustable in length by cooperating with the clamping plate assembly.

[0006] Preferably, the clamping plate assembly includes a lower cover plate, a movable plate, and an upper cover plate. The lower cover plate is a concave columnar structure positioned above the electric cylinder. The movable plate is positioned above the lower cover plate, and the upper cover plate is positioned above the movable plate. Rubber sealing strips are provided on the edges of both the upper and lower cover plates.

[0007] Preferably, a compression spring is provided inside the lower ring sleeve, and a humidity sensor is provided on the periphery of the lower ring sleeve.

[0008] Preferably, the lower end of the upper silicon carbide tube has a gradually narrowing opening, and the lower silicon carbide tube is slidably disposed inside the upper silicon carbide tube. The upper end of the lower silicon carbide tube has an flared opening. The narrowing opening and the flared opening cooperate to prevent the upper and lower silicon carbide tubes from separating and maintain a relatively sealed state.

[0009] Preferably, a CNC box is provided on the periphery of the lower ring sleeve, and the CNC box integrates a PLC control system for adjusting various components.

[0010] Preferably, a displacement sensor is provided below the lower cover plate.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] This invention utilizes a telescopic, dual-section silicon carbide tube structure driven by an electric cylinder to achieve dynamic and precise adjustment of the evaporation length, solving the core pain point of traditional fixed tube evaporators. When processing high-viscosity materials, the electric cylinder can move the clamping plate assembly, which in turn moves the upper silicon carbide tubes, shortening the tube length to reduce flow resistance and prevent blockage. For low-viscosity materials, the tubes can be extended to ensure sufficient evaporation. The combination of constriction and expansion ensures sealing while leveraging the excellent properties of silicon carbide material to improve heat transfer efficiency and reduce energy consumption. The modular quick-release structure also shortens maintenance time and reduces overall operating costs. Attached Figure Description

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1, as Figure 1-5 As shown, the specific design of the aforementioned key components is described below: An axially adjustable silicon carbide tube thin-film evaporator includes an upper tube sheet 1. An upper silicon carbide tube 4 is installed below the upper tube sheet 1 via a flange 12. Individual silicon carbide tubes can be removed individually by disassembling the flange 12 for easy maintenance and replacement. A lower silicon carbide tube 5 is disposed through a clamping plate assembly 6, and is slidably disposed inside the upper silicon carbide tube 4. The end of the lower silicon carbide tube 5 away from the upper silicon carbide tube 4 is disposed on the lower tube sheet 2. A lower ring sleeve 3 is disposed around the lower tube sheet 2, and an electric cylinder 7 is disposed within the lower ring sleeve 3. The output end of the electric cylinder 7 is connected to the clamping plate assembly 6, and the electric cylinder 7 can drive the clamping plate assembly 6 to move up and down. The upper silicon carbide tube 4 and the lower silicon carbide tube 5 can be adjusted in length by cooperating with the clamping plate assembly 6. The tube length is adapted through dynamic adjustment driven by the electric cylinder 7. When the electric cylinder 7 pushes the clamping plate assembly 6 to move, the clamping plate assembly 6 can then drive the upper silicon carbide tube 4 to move up and down, and the lower silicon carbide tube 5 slides inside the upper silicon carbide tube 4, effectively adjusting the evaporation length. This mechanical linkage design enables the equipment to respond to changes in material viscosity in real time. In high viscosity conditions, the tube is shortened to reduce flow resistance, and in low viscosity conditions, the tube is extended to improve evaporation efficiency. These innovations solve the industry pain points of low energy efficiency and poor adaptability of traditional fixed tube evaporators.

[0023] The clamping plate assembly 6 includes a lower cover plate 603, a movable plate 601, and an upper cover plate 602. The lower cover plate 603 is a concave columnar structure positioned above the electric cylinder 7. The movable plate 601 is positioned above the lower cover plate 603, and the upper cover plate 602 is positioned above the movable plate 601. Rubber sealing strips are provided on the edges of both the upper cover plate 602 and the lower cover plate 603. A compression spring 8 is installed inside the lower ring sleeve 3, and a humidity sensor 11 is installed around the lower ring sleeve 3. The lower end of the upper silicon carbide tube 4 has a gradually narrowing constriction 13. The lower silicon carbide tube 5 is slidably positioned inside the upper silicon carbide tube 4, and an flared end 14 is provided at the upper end of the lower silicon carbide tube 5. The constriction 13 and the flared end 14 cooperate to prevent the upper silicon carbide tube 4 and the lower silicon carbide tube 5 from separating, maintaining a relatively sealed state. A CNC box 10 is installed around the lower ring sleeve 3. A PLC control system is used to adjust various components. A displacement sensor 9 is installed below the lower cover plate 603. The electric cylinder 7 drives the lower cover plate 603 to move the moving plate 601 and the upper cover plate 602 up and down as a whole. The displacement sensor 9 provides real-time feedback on the position. The PLC control system dynamically adjusts the length of the tube according to the material characteristics. The concave upper cover plate 602 and lower cover plate 603 can enhance the sealing effect and strengthen the tight connection with the inner tube wall. The rubber sealing strips of the upper cover plate 602 and lower cover plate 603 enhance the sealing effect. The sealing cooperation of the constriction 13 and the expansion 14 forms a double guarantee. The mechanical limit prevents the tube from detaching. The rubber sealing strip can be made of fluororubber material with a temperature resistance of 200℃. The humidity sensor 11 monitors the working environment in real time and forms a closed-loop control system with the CNC box 10 to ensure the sealing reliability under different working conditions. Rubber sealing strips can be installed on the constricted opening 13 and the flared opening 14 to further enhance the sealing effect and completely solve the problem of thermal stress leakage. The modular design shortens the maintenance time. The silicon carbide tube has excellent corrosion resistance and can withstand long-term erosion by strong acids, alkalis and organic solvents, resulting in a long service life. The ultra-high thermal conductivity makes the heat transfer efficiency several times that of stainless steel, perfectly solving the industry pain points of traditional metal tubes such as easy corrosion and poor heat transfer.
