Multiple support columns 204 are symmetrically distributed around the axis of the heating barrel 1.

[0027] Furthermore, the sealing cap 201 seals the inside of the heating tank 1 with the sealing strip 203, which facilitates the rapid heating of the solution inside the heating tank 1.

[0028] The inner wall of the heating barrel 1 is fixedly connected to an upper support 205, a heat-concentrating plate 206 and a lower support 207 respectively.

The lower support 207 is located above the electric heating tube 2 and the heat-concentrating plate 206 is located between the lower support 207 and the upper support 205.

[0029] Furthermore, the heat-concentrating plate 206 gathers the heat from the lower electric heating tube 2 towards the center, making the heating barrel 1 more evenly heated.

[0030] To ensure timely removal of heated steam and prevent water vapor from entering the concentration process, thus reducing concentration efficiency and causing scale buildup inside the equipment, a water removal mechanism is installed, as per [reference needed]. Figure 1 and Figures 3-5 The dehydration mechanism includes a concentration tank 3, which concentrates the solution inside the concentration tank 3.

[0031] The dehydration mechanism also includes a stirring rod 301, the surface of which is rotatably connected to the surface of the sealing cover 201. The surface of the sealing cover 201 is fixedly connected to a stirring motor 302 and a temperature controller 303. The output shaft of the stirring motor 302 is fixedly connected to one end of the stirring rod 301 via a coupling. The bottom of the concentration tank 3 is slidably connected to the surface of the lower support 207, and the surface of the concentration tank 3 is slidably connected to the surface of the upper support 205. The stirring rod 301 is located inside the concentration tank 3.

[0032] Furthermore, the concentration tank 3 is easy to load, unload, and clean. The stirring motor 302 stirs the solution inside the concentration tank 3 through the stirring rod 301, so that the solution is heated evenly.

[0036] Furthermore, the gas evaporated inside the concentration tank 3 is liquefied inside the water outlet cylinder through the spiral dewatering pipe 314, thus discharging the water vapor inside the concentration tank 3.

[0037] By setting up a heating mechanism and a dehydration mechanism, the heating mechanism heats the evaporating solution through an electric heating tube 2, and the dehydration mechanism concentrates the solution inside the concentration tank 3 and removes water from the heated and evaporated solution. This solves the technical problem that existing concentration processes are prone to water vapor entering, which leads to reduced concentration efficiency and scale formation inside the equipment, affecting the normal operation of the equipment.

[0038] Working principle:

[0039] Before use, place the concentration tank 3 inside the heating tank 1. The lower surface of the concentration tank 3 is connected to the surface of the lower support 207, and the surface of the concentration tank 3 is connected to the surface of the upper support 205. A sealing groove 202 is provided on the upper end face of the heating tank 1. The end face of the heating tank 1 contacts the top of the sealing cover 201 through a sealing strip 203 provided on the inner wall of the sealing groove 202. The inner wall of the sealing cover 201 is threadedly connected to the surface of the heating tank 1 to maintain the airtightness of the heating tank 1. The solution is injected into the concentration tank 3 through the feed pipe provided above the sealing cover 201. A feed valve is provided on the surface of the feed pipe to control the flow. The opening and closing of the feed pipe is controlled by an electric heating tube 2 installed at the bottom of the heating tank 1, which heats the bottom of the concentration tank 3. A heat-concentrating plate 206 installed on the outside of the concentration tank 3 reflects the heat emitted by the electric heating tube 2 to the surface of the concentration tank 3, uniformly heating the solution inside. A stirring motor 302 installed on the upper surface of the sealing cover 201 drives a stirring rod 301 to rotate, stirring the solution inside the concentration tank 3 to ensure uniform heating and accelerate the heating process. The heated steam is discharged from the concentration tank 3 through an exhaust pipe 308. A one-way valve 311 is installed to prevent water vapor from flowing back into the exhaust pipe 308. After the gas inside the concentration tank 3 is discharged, it enters the air through the pressure relief pipe 307 installed on the surface of the sealing cover 201. The pressure relief valve 310 installed on the surface of the pressure relief pipe 307 maintains the balance between the air pressure inside the concentration tank 3 and the external air pressure. The steam discharged from the exhaust pipe 308 enters the upper end of the spiral dehydration pipe 314 through the one-way valve 311 installed on the surface of the exhaust pipe 308. The steam inside the spiral dehydration pipe 314 is condensed into liquid inside the dehydration cylinder 313 and flows out from the lower end of the spiral dehydration pipe 314, thus clearing the water vapor from the inside of the concentration tank 3. The inability of steam to escape affects the concentration efficiency. Cooling water inside the dewatering cylinder 313 enters from the inlet 315 at the bottom of the dewatering cylinder 313 and exits from the outlet 316 at the top of the dewatering cylinder 313. The temperature of the steam is monitored by the temperature controller 303 set above the sealing cover 201 to prevent the solution from evaporating completely due to excessive temperature. The temperature is controlled to evaporate and concentrate the solution until no liquid is discharged from the spiral dewatering pipe 314. Then the electric heating tube 2 is turned off. After cooling, the concentrated solution is discharged through the discharge pipe 304 at the bottom of the concentration tank 3. The discharge valve 305 set on the surface of the discharge pipe 304 controls the discharge switch.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
