Description

Technical Field

[0001] This utility model relates to the field of tortoise shell glue extraction, evaporation and concentration technology, specifically a tortoise shell glue extract evaporation and concentration device. Background Technology

[0002] Tortoise shell glue is an important raw material for traditional Chinese medicine. Its preparation process requires the evaporation and concentration of the aqueous extract. Existing evaporation and concentration equipment, such as single-effect evaporators, has problems such as low thermal energy utilization and low evaporation efficiency. The steam is directly condensed and discharged after evaporation, and the large amount of latent heat it carries is not effectively recovered, resulting in high energy consumption costs. In addition, the equipment structure is often not compact enough, and the gas-liquid separation effect is poor, which may affect the quality of the concentrated product.

[0003] Therefore, there is an urgent need for a special evaporation and concentration equipment for tortoise shell glue extract that can effectively recover and utilize waste heat, improve evaporation efficiency, and has a compact and reasonable structure. Utility Model Content

[0004] (a) Technical problems to be solved The purpose of this invention is to overcome the shortcomings of the existing technology and provide an evaporation and concentration device for tortoise shell glue extract.

A gas-liquid separator is fixed above the fixed frame via fixing bolts and a fixing plate. A heat exchanger is fixed within the fixed frame. A supporting plate is provided within the fixed frame, and a circulating pump is fixed above the supporting plate. A water tank is fixed above the fixed frame. The concentration tank is connected to the gas-liquid separator via an evaporation pipe, which has an upward inclination angle, allowing the condensate in the gas-liquid separator to flow back to the gas-liquid separator by gravity. A concentration tank; the side of the gas-liquid separator is connected to the inlet of the heat exchanger via a gas pipe; a water inlet pipe and an exhaust pipe are fixedly connected to the side of the heat exchanger; the heat exchanger is also connected to a spiral pipe, which is wound around the outer surface of the liquid inlet pipe of the concentration tank, the water inlet end of the spiral pipe is connected to the heat medium outlet of the heat exchanger, and the water outlet end of the spiral pipe is connected to the upper part of the water tank; the water inlet end of the circulation pump is connected to the bottom end of the water tank via a connecting pipe, and the water outlet end of the circulation pump is connected to the water inlet pipe of the heat exchanger.

[0006] Furthermore, the bottom of the concentration tank is fixed with an outlet pipe for discharging the concentrated liquid and an inlet pipe for inputting the extract to be concentrated.

[0008] Furthermore, the support plate is fixedly connected to the fixing frame by fixing bolts.

[0009] (III) Beneficial Effects: Compared with existing technologies, this tortoise shell glue extract evaporation and concentration equipment has the following advantages: I. This utility model utilizes the steam generated from the concentration tank, which is separated into gas and liquid, and then enters a heat exchanger to transfer heat to the circulating cooling water. The heated cooling water is no longer directly discharged or cooled, but flows into a spiral pipe to preheat the cold extract that is about to enter the concentration tank. This design realizes the cascade utilization of the system's waste heat, greatly reduces the energy required to heat the fresh extract, and significantly improves the thermal efficiency of the entire system.

[0010] Second, this invention features a preheated liquid feed that enters the concentration tank at a higher initial temperature, shortening the heating time within the tank and accelerating water evaporation, thereby improving concentration efficiency.

Detailed Implementation

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0014] like Figure 1-5 As shown, this utility model provides a technical solution: an evaporation and concentration device for tortoise shell glue extract, the main body of which is a rigid fixed frame 1 and a support leg 17. A concentration tank 3 is fixedly installed on the support leg 17. The concentration tank 3 is firmly connected to the fixed frame 1 by a fixing ring 4 welded to its outer wall and by fixing bolts 5.

[0015] Above the mounting bracket 1, a gas-liquid separator 7 is installed using fixing bolts 5 and a fixing plate 18. The inlet of the gas-liquid separator 7 is connected to the top of the concentration tank 3 via an evaporation pipe 6. It is worth noting that the evaporation pipe 6 is installed at a certain upward angle, with its high end connected to the gas-liquid separator 7 and its low end connected to the concentration tank 3. This slope design is to allow the condensate separated in the gas-liquid separator 7 to flow back to the concentration tank 3 automatically by gravity, thus preventing liquid from accumulating in the gas-liquid separator 7.

[0016] Inside the fixed frame 1, a heat exchanger 10 is fixedly installed. The gas outlet of the gas-liquid separator 7 is connected to the steam inlet of the heat exchanger 10 through a gas pipe 9. The heat exchanger 10 is usually a shell-and-tube heat exchanger 10, with steam flowing through the shell side and cooling water flowing through the tube side. A water inlet pipe 15 and an exhaust pipe 19 are welded onto the shell of the heat exchanger 10.

[0017] A key innovation of this application is the waste heat recovery system. The heat medium outlet of the heat exchanger 10 (i.e., the high-temperature cooling water outlet after being heated by steam) is connected to a spiral pipe 11. The spiral pipe 11 is tightly wrapped around the outer periphery of the liquid inlet pipe 13 of the concentration tank 3. The end of the spiral pipe 11 is connected to the upper part of the water tank 8 fixed above the mounting frame 1, which can preheat the liquid inlet pipe 13 through the spiral pipe 11.

[0018] Meanwhile, a support plate 12 is fixed inside the fixed frame 1 by fixing bolts 5. The circulation pump 14 is installed on the support plate 12. The inlet of the circulation pump 14 is connected to the bottom of the water tank 8 through the connecting pipe 16, and the outlet of the circulation pump 14 is connected to the water inlet pipe 15 of the heat exchanger 10. In this way, a complete circulating water circuit is formed: cooling water is pumped out from the bottom of the water tank 8 by the circulation pump 14 and enters the tube side of the heat exchanger 10. After absorbing the latent heat of condensation of the steam, the temperature rises and becomes high-temperature water. The high-temperature water then flows into the spiral pipe 11. When it flows in the spiral pipe 11, its heat is transferred through the pipe wall to the room temperature tortoise shell glue extract flowing through the liquid inlet pipe 13 to preheat it. After being cooled, the water flows back to the top of the water tank 8.

[0019] Work process: Start the circulation pump 14 to circulate the cooling water in the loop formed by the heat exchanger 10 and the spiral pipe 11.

[0020] The tortoise shell glue extract at room temperature is fed in through the inlet pipe 13. As it flows through the pipe section wound by the spiral pipe 11, the extract is preheated.

[0021] The preheated extract enters the concentration tank 3 (the concentration tank 3 can be an SN series double-effect concentration tank 3, the entry and exit of the extract in this concentration tank 3 can be controlled by a control valve or a manual control valve, the model is not limited here, its main function is to control the inflow and outflow of the extract), and is further heated to boiling by the built-in heating device (such as heating coil, etc.) to generate steam. At the same time, the temperature and pressure inside the concentration tank 3 are monitored by the temperature sensor and pressure sensor on the top of the concentration tank 3 (the model of the temperature sensor and pressure sensor is not limited here), and the detected values ​​are transmitted to the external display.

[0022] Steam carrying a small amount of liquid droplets enters the gas-liquid separator 7 through the inclined evaporation pipe 6. The droplets are separated and flow back to the concentration tank 3 by gravity, while the dry steam enters the shell side of the heat exchanger 10.

[0023] Inside the heat exchanger 10, steam exchanges heat with the cooling water in the tubes. The steam condenses and releases heat, and the condensate is discharged from the system through the exhaust pipe 19; while the cooling water is heated.

[0024] The heated cooling water flows into the spiral pipe 11 to preheat the cold extract in the liquid inlet pipe 13, thus completing the waste heat recovery.

[0025] The preheated water flows back to the water tank 8, and the extract in the concentration tank 3 is discharged from the outlet pipe 2 after reaching the predetermined concentration.

[0026] Through the above-described process, this application achieves energy recycling, which is particularly suitable for materials such as tortoise shell glue extract that require long-term concentration, resulting in significant energy-saving effects.
