Description

Technical Field

[0001] This utility model belongs to the field of brine concentration technology, specifically a salt lake brine concentration device. Background Technology

[0002] Salt lake brine concentration technology is one of the key steps in lithium resource extraction. Salt lake brine is rich in lithium, magnesium and other elements, and is an important source of raw materials for new energy industries such as lithium-ion batteries. However, the concentration of salt lake brine is often low and contains a large number of impurities, so it needs to be concentrated and purified to meet the needs of industrial applications.

[0003] Existing concentration technologies, such as solar evaporation, have long processing cycles and cannot meet the large domestic demand. Alternatively, mechanical steam technology can be used to concentrate brine, but this consumes relatively high amounts of energy, wastes resources, and increases production costs.

[0004] By filtering the brine and enhancing the filtration effect, the filtration time can be shortened. At the same time, excess heat generated by mechanical steam can be recovered and recycled, thereby reducing the cost required for brine concentration. Utility Model Content

[0005] To address the problems mentioned in the background section, this invention provides a salt lake brine concentration device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a salt lake brine concentration device, comprising a water storage tank, a water pump fixed to the outside of the water storage tank, a liquid delivery pipeline provided at one end of the water storage tank, a spiral conveying pipeline connected to one end of the liquid delivery pipeline, a recovery tank installed outside the liquid delivery pipeline, an annular conveying frame connected to one end of the spiral conveying pipeline, a nozzle installed at the bottom end of the annular conveying frame, a concentration tank fixed to the outside of the annular conveying frame, and a recovery mechanism provided inside the annular conveying frame;

[0007] The recycling mechanism includes a fan, a first air guide pipe, and a first solenoid valve. The fan is installed inside the annular conveyor frame. The top of the concentration tank is provided with a first air guide pipe, and the outside of the first air guide pipe is provided with a first solenoid valve. The outside of the recycling tank is connected to a second air guide pipe, and the outside of the second air guide pipe is provided with a second solenoid valve.

[0008] Preferably, the input end of the first gas guide tube is connected to a concentration tank, the output end of the first gas guide tube is connected to a recovery tank, the input end of the second gas guide tube is connected to a recovery tank, and the output end of the second gas guide tube is connected to a concentration tank.

[0009] Preferably, a stirring mechanism is installed on the outside of the water storage tank, a filtration mechanism is provided at the top of the water storage tank, a support frame is fixed inside the concentration tank, a combustion box is fixed at the top of the support frame, a fuel addition pipe is provided at one end of the combustion box, and an exhaust pipe is provided at the other end of the combustion box.

[0010] Preferably, the stirring mechanism includes a servo motor, a connecting rod, and stirring rods. The servo motor is fixed to the outside of the water storage tank, and a connecting rod is fixed to one end of the servo motor. Several sets of stirring rods are fixed to the outside of the connecting rod, and the stirring rods are arranged at equal intervals about the central axis of the connecting rod.

[0011] Preferably, the filtration mechanism includes a mounting frame, filter plates, a connecting plate, and fixing bolts. The mounting frame is located at the top of the water storage tank, and two sets of filter plates are installed inside the mounting frame. A connecting plate is located at the top of the mounting frame, and fixing bolts are located at the top of the connecting plate.

[0012] Preferably, the mounting frame is provided in three sets, the outer wall of the mounting frame is close to the inner wall of the water storage tank, the mounting frame and the water storage tank are slidably connected, and the surface of the filter plate is provided with several sets of holes.

[0013] Preferably, the fuel injection pipe passes through the concentration tank and the combustion chamber, and the output end of the fuel injection pipe is connected to the combustion chamber; the exhaust gas pipe passes through the concentration tank and the combustion chamber, and the input end of the exhaust gas pipe is connected to the combustion chamber.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention, through the coordinated arrangement of a fan, a first air guide pipe, and a first solenoid valve, enables the device to activate the fan when fuel is added and burned inside the combustion chamber, generating heat. This fan directs excess hot air through the first air guide pipe into the recovery tank, utilizing the waste heat generated during the brine concentration process in the combustion chamber. This heats the interior of the recovery tank and the brine transported within the spiral conveying pipe, shortening the concentration time after the brine enters the concentration tank. Furthermore, the user can control the opening and closing of the first and second solenoid valves to determine whether the hot air flows between the recovery tank and the concentration tank or only within the concentration tank. When concentrating the last portion of brine in the storage tank, since there is no brine left in the spiral conveying pipe, the flow of hot air can be cut off. The fan can then be activated to turbulent the hot air inside the concentration tank, allowing the brine to come into contact with the hot air. This facilitates the recovery and utilization of waste heat and enables rapid concentration of the last portion of brine.

[0016] This invention, through the combination of a servo motor, connecting rod, and stirring rod, enables the device to start the servo motor to drive the connecting rod and stirring rod to rotate, thereby accelerating the filtration rate and shortening the processing time.

[0017] This utility model, through the combination of structures such as mounting brackets, filter plates, and connecting plates, enables the device to take an appropriate number of mounting brackets and install them on the water storage tank, and fix them with connecting plates and fixing bolts. When brine is poured into the water storage tank, the filter plate can filter the brine. Different numbers of mounting brackets can be selected for filtration according to different types of brine, thereby achieving the purpose of facilitating the filtration of brine before processing.

[0027] Using the above scheme: by starting the water pump 4, the brine inside the water storage tank 1 can be transported through the infusion pipeline 5, so that the brine enters the interior of the annular conveyor frame 8 through the spiral conveyor pipeline 6 and is sprayed through the nozzle 9, so that the brine is spread on the surface of the support frame 12 and the combustion box 13 and then concentrated by heat. The concentrated substance is filtered through the holes on the surface of the support frame 12 and falls down for collection.

[0028] like Figures 1 to 6 As shown, the stirring mechanism 2 includes a servo motor 201, a connecting rod 202, and stirring rods 203. The servo motor 201 is fixed to the outside of the water storage tank 1. One end of the servo motor 201 is fixed to the connecting rod 202. Several sets of stirring rods 203 are fixed to the outside of the connecting rod 202. The stirring rods 203 are arranged at equal intervals about the central axis of the connecting rod 202.

[0029] like Figures 1 to 6As shown, the filtration mechanism 3 includes a mounting frame 301, filter plates 302, a connecting plate 303, and fixing bolts 304. The mounting frame 301 is located at the top of the water storage tank 1. Two sets of filter plates 302 are installed inside the mounting frame 301. The mounting frame 301 has three sets. The outer wall of the mounting frame 301 is close to the inner wall of the water storage tank 1. The mounting frame 301 and the water storage tank 1 are slidably connected. Several sets of holes are opened on the surface of the filter plates 302. The top of the mounting frame 301 is provided with a connecting plate 303, and the top of the connecting plate 303 is provided with fixing bolts 304.

[0030] The above solution allows for the installation of a variety of filter plates 302 based on the different types of brine required for concentration, thereby preventing the different densities of impurities in different brines from affecting the quality of subsequent concentration.

[0031] like Figures 1 to 6 As shown, the recycling mechanism 11 includes a fan 1101, a first air guide pipe 1102, and a first solenoid valve 1103. The fan 1101 is installed inside the annular conveyor frame 8. The top of the concentration tank 10 is provided with the first air guide pipe 1102, and the outside of the first air guide pipe 1102 is provided with the first solenoid valve 1103.

This utilizes the residual heat generated during the combustion of the combustion box 13 to concentrate the brine, thereby heating the inside of the recovery tank 7 and the brine transported inside the spiral conveying pipe 6 within the recovery tank 7. This shortens the concentration time of the brine after it enters the concentration tank 10. Furthermore, the user can control the opening and closing of the first solenoid valve 1103 and the second solenoid valve 1105 to control whether the hot air flows between the recovery tank 7 and the concentration tank 10 or only within the concentration tank 10. When concentrating the last portion of brine inside the reservoir 1, since there is no brine inside the spiral conveying pipe 6, the flow of hot air can be cut off. The hot air inside the concentration tank 10 can be turbulent by starting the fan 1101, so that the brine comes into contact with the hot air, thereby accelerating the concentration speed. After the brine is poured into the reservoir 1, the filter plate 302 can filter the brine. Different numbers of mounting brackets 301 can be selected for filtration according to different brines. The servo motor 201 is started to drive the connecting rod 202 and the stirring rod 203 to rotate, thereby accelerating the filtration rate. The water pump transports the brine through the spiral conveying pipe 6, the annular conveying frame 8 and the nozzle 9 and sprays it onto the top of the combustion box 13 for heating and concentration.
