[0002] Evaporation and concentration equipment is a highly efficient process device used in chemical, pharmaceutical, food, light industry, and environmental protection fields. It achieves continuous, efficient, and low-energy concentration of materials through multi-stage evaporation and concentration. Air-source heat pump evaporation and concentration equipment utilizes air energy as a heat source for evaporation and concentration. Air energy generally refers to the thermal energy in the air; this type of device uses air energy technology to improve energy efficiency and reduce dependence on traditional energy sources.

However, current devices are difficult to disassemble, making internal cleaning and maintenance troublesome, which greatly increases working time and intensity, resulting in low work efficiency. In addition, current devices usually do not have energy recovery functions, which means that the energy of the steam generated during evaporation cannot be recovered and reused, resulting in low energy utilization.

[0004] In response to this technical problem, this application proposes an air-source evaporation and concentration device. Utility Model Content

[0026] 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.

[0027] Reference Figures 1-3 One embodiment of this utility model provides an air-source heat pump evaporation and concentration device, comprising:

[0028] An evaporator 10 is used for evaporating and concentrating liquids. A top cover 2 is connected to the top of the evaporator 10 via a snap-fit ​​assembly, allowing the top cover 2 to be installed onto the evaporator 10 to create a closed state. A sealing ring 14 is fixedly connected to the top side of the evaporator 10. (Refer to...) Figure 4 A sealing groove is provided on the bottom side of the top cover 2, and a sealing ring 14 is inserted into the sealing groove to improve the sealing performance of the evaporator 10. (Refer to...) Figure 5 The top cover 2 is fixedly connected to the front and rear sides with a fixing plate 1, the evaporator 10 is fixedly connected to the front and rear sides with a buckle plate 11, the middle end of the fixing plate 1 is fixedly connected to a round tube 12, the inside of the round tube 12 is slidably connected to a slide rod 18, the bottom end of the slide rod 18 is fixedly connected to an insertion rod 19, one end of the insertion rod 19 is inserted into the middle end of the buckle plate 11, the inside of the slide rod 18 is threadedly connected to a round rod 17, the top end of the round rod 17 is fixedly connected to a rotating ring 16;

[0029] Specifically, rotating the rotating ring 16 causes the round rod 17 to rotate, which in turn causes the sliding rod 18 to slide in the round tube 12, thereby inserting or disengaging the insert rod 19 into the snap plate 11, thus fixing the top cover 2 onto the evaporator 10. After removing the top cover 2, the liquid is poured into the evaporator 10, and then the top cover 2 is installed on the evaporator 10. After the sealing ring 14 is inserted into the sealing groove, it will improve the sealing performance of the evaporator 10, thereby preventing heat from escaping from the gaps and improving the evaporation and concentration efficiency.

[0030] A condenser 7 is used for condensing steam. The condenser 7 and the top cover 2 are connected by a steam pipe 3. A heat pump 6 is installed on the rear side of the condenser 7. The condenser 7 and the heat pump 6 are connected by a metal pipe 5. The rear side of the heat pump 6 and the bottom side of the evaporator 10 are connected by a gas supply pipe 4. A wire mesh plate 13 is slidably connected inside the evaporator 10. A sealing ring 15 is fixedly connected to the bottom side of the top cover 2. A liquid outlet pipe 8 is fixedly connected to the front side of the bottom end of the evaporator 10. A control valve 9 is installed on the top side of the liquid outlet pipe 8. A base plate is fixedly connected to the bottom sides of the evaporator 10, the condenser 7 and the heat pump 6 by a support leg.

[0031] Specifically, the evaporator 10 absorbs heat from the surrounding air to heat the internal liquid, thereby evaporating the water or gaseous substances in the liquid into steam. Liquid droplets mixed in the steam are blocked by the wire mesh plate 13 and continue to evaporate and concentrate. The steam flows into the condenser 7 through the steam pipe 3. The condenser 7 absorbs the heat in the steam, thereby converting the steam into liquid and collecting it. The absorbed heat enters the heat pump 6 through the metal pipe 5. The heat pump 6 pressurizes the heat flow to raise the temperature again and delivers it to the evaporator 10 through the gas supply pipe 4, thereby supplying the evaporator 10 to heat the liquid. After the liquid evaporates and concentrates, the control valve 9 is opened so that the liquid is collected through the liquid outlet pipe 8. The sealing effect of the evaporator 10 is further improved by the sealing ring 15.

[0032] Working principle: Rotating the rotating ring 16 causes the round rod 17 to rotate, which in turn causes the sliding rod 18 to slide in the round tube 12, allowing the insertion rod 19 to insert into or disengage from the snap plate 11, thus fixing the top cover 2 onto the evaporator 10. After removing the top cover 2, the liquid is poured into the evaporator 10, and then the top cover 2 is installed back onto the evaporator 10. The sealing ring 14, after being inserted into the sealing groove, improves the sealing performance of the evaporator 10, and the sealing ring 15 further enhances the sealing effect of the evaporator 10, preventing heat from escaping through gaps. When the evaporator 10 is started, it absorbs heat from the surrounding air to heat the liquid inside. Heating evaporates the water or gaseous substances in the liquid into steam. The liquid droplets mixed in the steam are blocked by the wire mesh plate 13 and continue to evaporate and concentrate. The steam flows into the condenser 7 through the steam pipe 3. The condenser 7 absorbs the heat in the steam, thereby converting the steam into liquid and collecting it. The absorbed heat enters the heat pump 6 through the metal pipe 5. The heat pump 6 pressurizes the heat flow to raise the temperature again and delivers it to the evaporator 10 through the gas supply pipe 4, thereby supplying the evaporator 10 to heat the liquid. After the liquid evaporates and concentrates, the control valve 9 is opened so that the liquid is collected through the liquid outlet pipe 8.

[0033] 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.
