Description

Technical Field

[0001] The utility model relates to the technical field of evaporators, in particular to a device which utilizes the liquid level height in an evaporator to realize automatic brine reflux. Background Art

[0002] Evaporation is the physical process of converting a liquid into a gas. Generally speaking, an evaporator is an object that converts liquid substances into a gas. Industrially, there are numerous evaporators, one of which is used in refrigeration systems. In the salt production process, brine is typically preheated in a preheater before being fed into the evaporator. The brine is then pumped into the preheater via a feed pump, where it circulates before entering the evaporator, where it continues to circulate and produce salt.

[0003] Patent publication number CN220478134U discloses a device that utilizes the liquid level within an evaporator to automatically reflux brine. The device comprises a base plate, a brine reservoir, a first delivery pipe, a feed pump, a second delivery pipe, a preheater, a third delivery pipe, a material pump, a fourth delivery pipe, an electromagnetic reversing valve, a return pipe, a fifth delivery pipe, and an evaporator tank assembly. The patent incorporates an evaporator tank assembly that uses first and second liquid level sensors to detect the liquid level within the evaporator tank and control the return valve, ensuring that brine remains flowing in all pipes, reducing pressure on the pumps and pipes and enabling normal operation of the equipment.

[0004] Although the above device solves the problem of automatic brine reflux, it still has the following shortcomings:

[0005] When the liquid in the evaporator tank flows back to the brine pool through the reflux pipe, since the refluxed liquid from the evaporator tank is the brine that has been heated by the preheater, it will mix with the unheated brine when it flows back into the brine pool again. This causes the refluxed hot brine to need to be heated by the preheater again, resulting in a waste of heat resources and inconvenience. Utility Model Content

[0006] In view of the deficiencies of the prior art, the utility model provides a device which utilizes the liquid level in the evaporator to realize automatic brine reflux, thereby reducing the waste of heat resources.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a device for realizing automatic reflux of brine by utilizing the liquid level height in the evaporator, comprising an evaporator assembly, a reversing valve unit, a reflux end and an evaporation sensor, characterized in that an independent insulation unit is connected to one side of the evaporator assembly, the independent insulation unit comprises an insulation barrel structure, the outer side of the insulation barrel structure is detachably connected to a reflux pipe, the end of the reflux pipe is detachably connected to the reflux end of the outer side of the reversing valve unit, a conveying assembly is connected between the outer side of the insulation barrel structure and the evaporator assembly, and the outer side of the insulation barrel structure is connected to a heat circulation unit.

[0008] Furthermore, the conveying component includes a water pump, a water inlet pipe is connected to one side of the evaporator component, the output pipes at both ends of the water pump are respectively connected to the insulation barrel structure and the water inlet pipe, and the bottom outer wall of the insulation barrel structure is fixedly connected to the insulation barrel sensor, and the insulation barrel sensor is electrically connected to the controller of the water pump through a cable.

[0009] Furthermore, the heat circulation unit includes an insulation circulation pipe and an evaporation circulation pipe, which are respectively sleeved on the outer walls of the insulation barrel structure and the evaporator assembly. A water storage tank is provided on the outside of the insulation barrel structure. Both sides of the water storage tank are fixedly connected with a first delivery pipe. The two first delivery pipes respectively pass through the insulation barrel structure and the evaporator assembly, and the two first delivery pipes are respectively connected to the insulation circulation pipe and the evaporation circulation pipe. A second delivery pipe is fixedly connected between the other ends of the insulation circulation pipe and the evaporation circulation pipe, and a water pump is connected to the water storage tank.

[0010] Furthermore, a first insulation layer is installed on the outside of the insulation barrel structure, and the first insulation layer is sleeved on the outer wall of the insulation circulation pipe.

[0011] Furthermore, a second thermal insulation layer is installed on the outer side of the evaporator assembly, and the second thermal insulation layer is sleeved on the outer wall of the evaporation circulation pipe.

[0012] Furthermore, the return pipe is an insulation pipe.

[0013] Furthermore, the second conveying pipeline is an insulation pipe.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The utility model arranges the heat preservation barrel structure and the return pipe so that the hot water returning from the return pipe can be collected by the heat preservation barrel structure without being mixed with the initial normal temperature brine, so that the heated brine can be collected separately, realizing heat recovery and reducing the waste of heat resources.

The utility model has a simple structure, is easy to operate and has strong practicality. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] like Figures 1 to 5 As shown, a device for realizing automatic reflux of brine by utilizing the liquid level height in the evaporator includes an evaporator assembly 1, a reversing valve unit 2, a reflux end 3 and an evaporation sensor 6. An independent insulation unit is connected to one side of the evaporator assembly 1. The independent insulation unit includes an insulation barrel structure 15. The outer side of the insulation barrel structure 15 is detachably connected to a reflux pipe 7. The end of the reflux pipe 7 is detachably connected to the reflux end 3 on the outer side of the reversing valve unit 2. A conveying assembly is connected between the outer side of the insulation barrel structure 15 and the evaporator assembly 1. The outer side of the insulation barrel structure 15 is connected to a heat circulation unit.

[0024] like Figure 1 As shown, the device for realizing automatic reflux of brine by utilizing the liquid level height in the evaporator in the present invention is similar in structure to the existing device for realizing automatic reflux of brine by utilizing the liquid level height in the evaporator. For example, patent CN220478134U discloses a device for realizing automatic reflux of brine by utilizing the liquid level height in the evaporator. The main improvement of the present invention is to reduce the waste of heat resources.

[0025] like Figures 1 to 4As shown, when the device of the utility model that utilizes the liquid level height in the evaporator to realize automatic reflux of brine is in use, the reversing valve unit 2 transmits the brine from the reflux end 3, and it will enter the insulation barrel structure 15 through the reflux pipe 7. The insulation barrel structure 15 collects the hot water that has been heated by the preheater. When the brine in the evaporator component 1 evaporates, its liquid level is lower than the evaporation sensor 6. At this time, the conveying unit is started to re-input the hot brine in the insulation barrel structure 15 into the evaporator component 1 until the liquid level is higher than the height of the evaporation sensor 6, and then the output is stopped; the hot water is added to the evaporator component 1 first, thereby reducing the waste of heat resources.

[0026] By setting up the heat preservation barrel structure 15 and the return pipe 7, the hot water returning from the return pipe 7 can be collected by the heat preservation barrel structure 15 without being mixed with the initial room temperature brine, so that the heated brine can be collected separately, realizing heat recovery and reducing the waste of heat resources. By utilizing the transmission of the conveying component, when the evaporator component 1 needs to add brine, hot water is output from the heat preservation barrel structure 15 first, further reducing the waste of heat resources caused by preheater heating.

[0027] like Figure 1 、 Figure 2 、 Figure 3 and Figure 5 As shown, the conveying component includes a water pump 8, a water inlet pipe 9 is connected to one side of the evaporator component 1, the output pipes at both ends of the water pump 8 are respectively connected to the insulation barrel structure 15 and the water inlet pipe 9, and the bottom outer wall of the insulation barrel structure 15 is fixedly connected to the insulation barrel sensor 14, and the insulation barrel sensor 14 is electrically connected to the controller of the water pump 8 through a cable.

[0028] Specifically, when the brine level in the evaporator assembly 1 is lower than the evaporation sensor 6, the evaporation sensor 6 will send a signal to the water pump 8, and the water pump 8 will start and transport the hot brine in the insulation barrel structure 15 to the water inlet pipe 9, and then enter the evaporator assembly 1. This arrangement allows the hot brine in the insulation barrel structure 15 to enter the evaporator assembly 1 first, thereby further reducing the consumption and waste of heat resources.

[0029] like Figure 1 、 Figure 2 and Figure 4As shown, the heat circulation unit includes an insulation circulation pipe 16 and an evaporation circulation pipe 10, which are respectively sleeved on the outer wall of the insulation barrel structure 15 and the evaporator assembly 1. A water storage tank 11 is provided on the outside of the insulation barrel structure 15. Both sides of the water storage tank 11 are fixedly connected with a first delivery pipe 5. The two first delivery pipes 5 respectively pass through the insulation barrel structure 15 and the evaporator assembly 1, and the two first delivery pipes 5 are respectively connected to the insulation circulation pipe 16 and the evaporation circulation pipe 10. A second delivery pipe 13 is fixedly connected between the other end of the insulation circulation pipe 16 and the evaporation circulation pipe 10, and a water pump is connected to the water storage tank 11.

[0030] Specifically, when the insulation barrel structure 15 is storing hot brine, the evaporator assembly 1 performs evaporation and generates heat. At this time, the water pump in the water storage tank 11 works, and the normal temperature water enters the evaporation circulation pipe 10 which is sleeved on the outer wall of the evaporator assembly 1 through the first delivery pipe 5 on one side thereof. The normal temperature water in the evaporation circulation pipe 10 will realize heat exchange with the evaporator assembly 1. The hot water after heat exchange will pass through the second delivery pipe 13 into the insulation circulation pipe 16 which is sleeved on the outer wall of the insulation barrel structure 15. The insulation circulation pipe 16 will always fit with the insulation barrel structure 15, so that the hot water can ensure the temperature of the hot brine in the insulation barrel structure 15, so that the insulation effect of the insulation barrel structure 15 is better, and thus the output temperature of the hot brine can be guaranteed.

[0031] like Figure 1 、 Figure 2 and Figure 3 As shown, a first insulation layer 4 is installed on the outside of the insulation barrel structure 15, and the first insulation layer 4 is sleeved on the outer wall of the insulation circulation pipe 16. Through the arrangement of the first insulation layer 4, the insulation effect of the insulation circulation pipe 16 can be improved.

[0032] like Figure 1 、 Figure 2 and Figure 3 As shown, a second insulation layer 12 is installed on the outside of the evaporator assembly 1, and the second insulation layer 12 is sleeved on the outer wall of the evaporation circulation pipe 10. The second insulation layer 12 can improve the insulation effect of the evaporation circulation pipe 10.

[0033] like Figure 1 、 Figure 2 、 Figure 3 and Figure 5 As shown, the return pipe 7 is provided with a heat preservation pipe. Such arrangement can ensure that the return pipe 7 can guarantee the temperature of the hot brine to the greatest extent when transmitting the hot brine.

[0034] like Figure 4 As shown, the second delivery pipe 13 is a heat-insulating pipe. This arrangement ensures that the brine after heat exchange has good heat-insulating performance as much as possible.

[0035] Among them, the water delivery pump 8, the water extraction pump and the insulation bucket sensor 14 are all existing mature technologies and will not be described in detail here.

[0036] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
