Detailed implementation mode

[0054] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0055] Embodiment 1

[0056] A heat pump concentrator efficiency-enhancing waste heat absorption device, as Figure 1 shown, includes: a liquid storage frame 1; a water pipe 2, there are 6 water pipes 2, and 3 adjacent water pipes 2 are respectively arranged on the left and right sides of the liquid storage frame 1; a heat storage cavity 3, there are 3 heat storage cavities 3, and the heat storage cavities 3 are respectively arranged on the liquid storage frame 1; a heat absorption mechanism 4, there are 3 heat absorption mechanisms 4, and the heat absorption mechanisms 4 are also respectively arranged on the liquid storage frame 1, used to absorb the heat outside the evaporator and transfer the heat to the liquid stored in the liquid storage frame 1; a hot air mechanism 5, there are 3 hot air mechanisms 5, and the hot air mechanisms 5 are respectively arranged between the left and right parts of the liquid storage frame 1, used to accelerate the air flow on the surface of the evaporator and prevent frosting on its surface.

[0057] It should be noted that as an energy-saving and efficient industrial device, the heat pump concentrator is mainly used for concentrating liquid materials. The evaporator is one of the core components of the heat pump concentrator, mainly responsible for absorbing low-temperature heat energy to evaporate the water in the liquid material. During the concentration operation, the original liquid is first injected into the distillation kettle. There is a heating component in the distillation kettle to raise the temperature of the original liquid and evaporate the water vapor. The water vapor will enter the evaporator, and the remaining original liquid will form a concentrated liquid after the operation of the distillation kettle. After the concentration is completed, it will be discharged out through the concentrated liquid outlet. When the water vapor enters the inside of the evaporator, the water vapor will be cooled and liquefied and discharged from the distilled water outlet under the action of the water pump and the water tank. During the process of the evaporator reducing the temperature of the water vapor, the cooling device inside the evaporator exchanges heat with the water vapor, and the surplus recovery can be realized through the heat absorption mechanism 4 to assist the distillation kettle in heating the material, thereby improving the efficiency of the heat pump concentrator.

[0058] As Figure 1 and Figure 2 shown, the heat absorption mechanism 4 includes: a contact cavity 41. There are 3 contact cavities 41, and the contact cavities 41 are also slidably arranged on the liquid storage frame 1. The inner sides of the contact cavities 41 are all arc-shaped structures that fit the surface of the evaporator; the first springs 42. There are 9 first springs 42. Every adjacent 3 first springs 42 are in a group, and each group of first springs 42 is respectively arranged between the adjacent contact cavity 41 and the liquid storage frame 1; the liquid leakage channels 43. There are 3 liquid leakage channels 43, and the liquid leakage channels 43 are all arranged on the liquid storage frame 1, and the liquid leakage channels 43 are connected to the adjacent contact cavity 41.

[0059] It should be noted that during the heat pump concentration operation, the device is fixed on the evaporator through the contact cavity 41, and the liquid is injected into the liquid storage frame 1 through the water pipe 2. The contact cavity 41 adopts an arc-shaped structure, and it can closely fit the surface of the evaporator through the elastic pressure of the first spring 42, so as to maximize the contact area and directly absorb the waste heat dissipated from the outer wall of the evaporator. The heat absorbed by the contact cavity 41 will be transferred to the inside of the liquid storage frame 1 to exchange heat with the liquid inside the liquid storage frame 1. At the same time, the heat storage cavity 3 can further store the excess heat to form a heat buffer. The liquid leakage channel 43 can be externally connected to a water pipe to discharge the excess liquid outward to avoid affecting the absorption of the heat on the surface of the evaporator by the contact cavity 41. The heat-absorbed liquid is discharged outward through the water pipe 2 and transfers the heat to the distillation kettle, thereby reducing the heat source consumption of the compressor, shortening the heating time of the compressor, and improving the overall working efficiency of the heat pump concentrator. The liquid heated by the distillation kettle will pass through the condenser. The condenser cools it down and then conveys it back to the inside of the evaporator to cool and liquefy the water vapor again, thus forming a closed cycle.

[0060] As Figure 1 and Figure 3As shown in the figure, the hot air mechanism 5 includes: three first ventilation plate members 51, which are respectively arranged on the right side of the liquid storage frame 1; three second ventilation plate members 52, which are respectively arranged on the left side of the liquid storage frame 1; and six fans 53. Adjacent fans 53 are grouped together, and each group of fans 53 is arranged on the adjacent first ventilation plate member 51.

[0061] It should be noted that as a component for reducing the temperature of water vapor to liquefy it, when the surface of the evaporator interacts with the surrounding water vapor, frosting may occur on its surface, affecting the working efficiency of the heat pump concentrator. By starting the fans 53 on the first ventilation plate member 51, hot air will be formed when the air flow passes through the heat storage cavity 3, and the air duct will be connected to the second ventilation plate member 52, so as to transport the air flow to the easily frosted parts. The warm air flow can accelerate the evaporation of water and prevent low-temperature frosting.

[0062] Embodiment 2

[0063] On the basis of Embodiment 1, as Figure 1 and Figure 4 shown, it further includes a stabilizing mechanism 6, which includes: a mounting frame 61 arranged on the upper left side of the liquid storage frame 1; a first hydraulic cylinder 62 arranged on the mounting frame 61; a pressing plate 63 arranged on the telescopic end of the first hydraulic cylinder 62; two second hydraulic cylinders 64, which are both arranged on the front and rear sides of the pressing plate 63; and two clamping plates 65, which are respectively rotatably arranged on the telescopic ends of the adjacent second hydraulic cylinders 64 and are respectively rotatably arranged on the front and rear sides of the pressing plate 63.

[0064] It should be noted that when fixing this device to the evaporator, the stability of the device can be enhanced through the stabilizing mechanism 6. The first hydraulic cylinder 62 drives the pressing plate 63 to press down, and then the second hydraulic cylinders 64 control the clamping plates 65 to clamp the evaporator from the front and rear sides to ensure its stable contact with the contact cavity 41, thereby enhancing the overall stability of this device.

[0065] As Figure 1 and Figure 5 shown, it further includes a closing mechanism 7, which includes: a driving motor 71 arranged on the upper right side of the liquid storage frame 1; a rotating disk 72 arranged on the output shaft of the driving motor 71; three limit members 74, which are respectively arranged on the right side of the liquid storage frame 1; a blocking disk 73 with three guiding grooves opened thereon, and the blocking disk 73 is slidably arranged on the limit members 74 and is engaged with the rotating disk 72, and the blocking disk 73 can block the first ventilation member.

[0066] It should be noted that when the temperature of the evaporator is too low, the driving motor 71 drives the rotating disk 72, and under the guiding action of the limiting member 74, the blocking disk 73 is pushed to slide, covering the first ventilation plate member 51 to reduce the intake of cold air, thereby maintaining the surface temperature of the evaporator.

[0067] As Figure 1 and Figure 6 shown, it further includes an anti-overflow mechanism 8, and the anti-overflow mechanism 8 includes: threaded members 82, there are 3 threaded members 82, and the threaded members 82 are respectively arranged on adjacent liquid leakage channels 43 in a threaded manner, and the threaded members 82 are all detachable connection structures; connecting rods 81, there are 3 connecting rods 81, and the connecting rods 81 are respectively arranged on the left sides of adjacent threaded members 82, and the connecting rods 81 are all slidably connected to adjacent liquid leakage channels 43; water-absorbing members 83, there are 3 water-absorbing members 83, and the water-absorbing members 83 are respectively arranged on the left sides of adjacent connecting rods 81, and the water-absorbing members 83 are all slidably connected to adjacent liquid leakage channels 43, and the water-absorbing members 83 can absorb the liquid in adjacent liquid leakage channels 43.

[0068] It should be noted that when the liquid flow rate in the liquid leakage channel 43 increases abnormally, the water-absorbing member 83 adsorbs excessive liquid to prevent overflow. The threaded member 82 adopts a detachable design, which is convenient for regularly cleaning or replacing the water-absorbing member 83 and reducing the downtime.

[0069] As Figure 1 and Figure 7 shown, it further includes a heat preservation mechanism 9, and the heat preservation mechanism 9 includes: an installation ring 91, and the installation ring 91 is arranged on the left side of the liquid storage frame 1; a rubber ring 92, and the rubber ring 92 is arranged on the installation ring 91.

[0070] It should be noted that the installation ring 91 and the rubber ring 92 form a composite heat preservation layer, reducing the heat dissipation of the liquid storage frame 1 to the environment, maintaining the stability of the liquid temperature, and improving the utilization rate of waste heat.

[0071] As Figure 1 and Figure 8 shown, it further includes a buffer mechanism 10, and the buffer mechanism 10 includes: buffer members 101, and the buffer members 101 are respectively slidably arranged on the pressing plate 63; second springs 102, there are 4 second springs 102, and the second springs 102 are respectively arranged between the pressing plate 63 and the buffer members 101.

[0072] It should be noted that the buffer members 101 and the second springs 102 can form a shock absorption system to absorb the vibration impact generated when the device holds the evaporator, preventing mechanical stress from damaging the evaporator or the contact cavity 41.

[0073] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes may be made therein without departing from the principles and spirit of the invention, and the scope of the invention is defined by the appended claims and their equivalents.
