Description

Technical Field

[0001] This utility model relates to the field of evaporation crystallization device technology, and in particular to a condensate recovery structure for a triple-effect evaporation crystallization device. Background Technology

[0002] The triple-effect evaporation crystallization unit is a highly efficient and energy-saving solution concentration and crystallization device, widely used in chemical, pharmaceutical, and food industries. This device utilizes the triple-effect evaporation principle, through multi-stage series connection and step-by-step pressure reduction, to fully utilize the latent heat of the steam in the previous effect, significantly reducing energy consumption. The material is evaporated and concentrated sequentially between each effect until it becomes supersaturated and crystals precipitate, ultimately achieving the concentration and crystallization separation of the material. The device has a compact structure, continuous and stable operation, and can effectively improve production efficiency and product purity.

[0003] The triple-effect evaporation crystallization unit mainly consists of a heater, an evaporation system, a crystallization system, a condenser, a circulating pump, a separator, and pipeline valves. The heater provides a heat source to promote material evaporation. The evaporation system concentrates the solution step by step under multi-effect series conditions. The crystallization system controls the temperature and concentration to promote crystal precipitation. The condenser is responsible for recovering secondary steam to generate condensate. The circulating pump ensures continuous flow of material in the system. The separator is used for gas-liquid separation to improve evaporation efficiency. The overall structure is compact, energy-efficient, and suitable for continuous and stable operation.

[0004] Existing triple-effect evaporation crystallization devices have the characteristics of high efficiency, low energy consumption, stable continuous operation, strong material adaptability, and controllable crystallization particle size. However, the condenser load is high in the high-temperature environment of summer, which leads to a decrease in condensation effect. To address this issue, a condensate recovery structure for triple-effect evaporation crystallization devices is proposed. Utility Model Content

[0032] 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.

[0033] Reference Figures 1-3This utility model provides an embodiment of a condensate recovery structure for a triple-effect evaporation crystallization device, comprising a condenser body 1, an input pipe 2 fixedly connected to the input end of the condenser body 1, through which steam in the triple-effect evaporation crystallization device enters the condenser body 1, an output pipe 3 fixedly connected to the output end of the condenser body 1, a secondary condensation assembly installed on the side of the output pipe 3, a cooling fan 4 installed inside the secondary condensation assembly, and a fixing assembly installed inside the cooling fan 4; the secondary condensation assembly includes a heat spreader plate 5, which is located outside the output pipe 3, and uses the heat spreader plate 5 to conduct heat from the output pipe 3; a heat conduction pipe 6 and a mounting bracket 8 are fixedly connected to the top of the output pipe 3, and the heat from the heat spreader plate 5 is conducted through the heat conduction pipe 6; heat dissipation fins 7 are fixedly connected to the side of the heat conduction pipe 6; and the cooling fan 4 is located inside the mounting bracket 8, dissipating heat from the heat conduction pipe 6 and the heat spreader plate 5 with the cooperation of the heat dissipation fins 7 and the cooling fan 4. Both the output tube 3 and the heat pipe 6 are made of copper metal. Copper metal can efficiently conduct heat energy. The output tube 3 is m-shaped. The m-shaped tube can effectively increase the contact area between the output tube 3 and the heat spreader 5, thereby improving the heat conduction efficiency.

[0034] Reference Figure 1 , Figure 4 and Figure 5 The fixing assembly includes a fixing shell 9, which is fixedly connected to the inside of the cooling fan 4, protecting the internal structure. A rod 10 is slidably connected inside the fixing shell 9, and a baffle 11 is fixedly connected to the outside of the rod 10. Moving the baffle 11 moves the rod 10. A movable plate 12 is fixedly connected to the side of the baffle 11, controlling the movement of the rod 10 by moving the baffle 11. A spring 13 is sleeved around the outer periphery of the rod 10, positioned between the fixing shell 9 and the baffle 11. The pressure generated by the interaction of the spring 13 and the baffle 11 causes the rod 10 to move outward. A slot 14 is provided inside the mounting bracket 8, and the rod 10 engages with the slot 14, moving outward to engage inside the slot 14.

[0035] Reference Figure 1 , Figure 4 and Figure 5 The fixed housing 9 has an internal slot 15, and the movable plate 12 is slidably connected inside the slot 15, providing space for the movement of the movable plate 12. A positioning block 16 is fixedly connected to the side of the cooling fan 4, and a positioning groove 17 is provided inside the mounting bracket 8. The positioning block 16 is slidably connected inside the positioning groove 17, and the mounting position of the cooling fan 4 is fixed by the cooperation of the positioning block 16 and the positioning groove 17. A filter 18 is installed at the end of the output pipe 3 to filter harmful substances in the condensate from the output pipe 3.

[0036] Working principle: The steam of the triple-effect evaporation crystallization device enters the condenser body 1 from the input pipe 2, and after condensation, it is output from the output pipe 3. When the uncondensed steam flows in the output pipe 3, the heat is conducted to the heat conduction pipe 6 through the heat spreader plate 5. After the heat dissipation fins 7 and the heat dissipation fan 4 work together, the heat on the heat conduction pipe 6 is dissipated, thereby causing the steam in the output pipe 3 to condense into water. It can help the condenser body 1 to condense under high temperature and high load conditions, ensuring the condensation effect of the device.

[0037] The moving plate 12 moves the baffle 11 and the plug rod 10 towards the center, causing the plug rod 10 to disengage from the slot 14 of the mounting bracket 8. The cooling fan 4 can then be removed for cleaning and maintenance. After cleaning and maintenance, the cooling fan 4 is put back into the mounting bracket 8. With the help of the pressure applied by the spring 13 to the baffle 11, the baffle 11 is forced to move the plug rod 10 outward and into the slot 14, thus achieving quick disassembly and assembly of the cooling fan 4 and improving the efficiency of cleaning and maintenance of the cooling fan 4.

[0038] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
