Description

Technical Field

[0001] The invention relates to the technical field of mixing devices, in particular to an electrolyte online mixing module. Background Art

[0002] Electrolyte is one of the main raw materials for battery production. It mainly realizes the conductive function, allowing the current to flow unimpeded in the battery, thereby generating electrochemical reactions and realizing the charging or discharging function of the battery.

[0003] Traditional electrolyte configuration mainly uses a feed pipe to send materials to a stirring tank for stirring and mixing. Since the raw materials need to be concentrated in the stirring tank, in order to produce a large amount of electrolyte at one time, the volume of the stirring tank needs to be large enough, which leads to a relatively large overall electrolyte production line, which in turn leads to problems such as large equipment space occupation and high production line construction costs, as well as low equipment utilization and poor quality stability caused by intermittent operation. There are also safety hazards caused by the presence of a large number of solvents on site. To this end, in response to the above problems, an electrolyte online mixing module is designed to better meet actual use needs. Summary of the invention

[0004] The object of the present invention is to provide an electrolyte online mixing module to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an electrolyte online mixing module, comprising a mounting frame and a feed pipe, the mounting frame is fixed with a feed pipe, and each feed pipe is installed with a pressure regulating valve, a flow meter, a flow regulating valve, a switch valve and a check valve, the feed pipe is interconnected with the feed port of a static mixer through a check valve, the discharge port of the static mixer is interconnected with the heat exchanger through a conduit, a spoiler mechanism and a diverter mechanism are installed in the heat exchanger, the heat exchanger is interconnected with a pump through a conduit, and the pump is connected with a three-way valve through a conduit.

[0006] Preferably, the feed pipe is connected to the nitrogen pipe through a switch valve. Through the above structure, the air in the pipeline can be emptied to avoid the influence of impurities in the external air on the mixing of materials, thereby ensuring the production quality.

[0007] Preferably, a water inlet is provided on the lower side of the heat exchanger, and the water inlet is interconnected with the cooling water inlet pipe, a water outlet is provided on the upper side of the heat exchanger, and the water outlet is interconnected with the cooling water return pipe, a liquid inlet is provided on the lower left end of the heat exchanger, and the liquid inlet is interconnected with the static mixer discharge port through a conduit, a liquid outlet is provided on the upper left end of the heat exchanger, and the liquid outlet is interconnected with the pump through a conduit, the water inlet, the cooling water inlet pipe, the liquid inlet and the cooling water return pipe can ensure the normal flow of cooling water, and the inlet and the outlet can ensure the normal entry and exit of materials, thereby providing a basic guarantee for the temperature control of materials.

[0008] Preferably, a heat exchange tube is installed in the heat exchanger, and the right end of the heat exchange tube is interconnected with the guide box. A partition is also fixed in the heat exchanger, and the partition separates the heat exchange tube into upper and lower parts. The heat exchange tube can be separated by the partition, thereby achieving the separation of materials and ensuring the normal circulation of materials in the heat exchanger.

[0009] Preferably, the spoiler mechanism includes a rotating shaft, a water wheel, a circular plate, a protrusion, a spoiler, a push rod, a sliding rod and a spring. The rotating shaft bearing is connected in the heat exchanger, and a water wheel is fixed on the rotating shaft, and the water wheel is located directly above the water inlet. During the operation of the device, the water flow and the water wheel can provide a basic force for the rotation of the rotating shaft, thereby ensuring the normal operation of the device.

[0010] Preferably, a circular plate is evenly fixed on the rotating shaft, and a convex block with an arc-shaped structure is fixed on the circular plate. The convex block is driven to rotate by the circular plate, which can provide a basic guarantee for the movement of the spoiler.

[0011] Preferably, the spoiler is arranged in the heat exchanger, and the spoiler is slidably connected to the rotating shaft, and a through hole is opened on the spoiler. At the same time, a top rod is fixed to the spoiler, and the top rod and the protrusion are slidably connected. The spoiler can be moved under force through the sliding action between the top rod and the protrusion. Through the action of the spoiler, the cooling water in the heat exchanger can be disturbed, thereby improving the cooling effect.

[0012] Preferably, a sliding rod is fixed on the spoiler, and the sliding rod is slidably connected to the heat exchanger, and one end of a spring is fixed on the sliding rod, and the other end of the spring is fixed in the heat exchanger.

The fixed plate is also fixed with one end of the second cross bar, and the other end of the second cross bar is fixed with a second sealing plug, and the second sealing plug cooperates with the outer arc groove on the diversion box to achieve a sealing effect. At the same time, the length of the second cross bar is greater than the length of the first cross bar. When the sliding bar moves, the fixed plate, the first cross bar, the first sealing plug, the second cross bar and the second sealing plug can be driven to move synchronously. By controlling the first sealing plug and the second sealing plug to seal and separate with the arc grooves at different positions on the diversion box, the outflow position of the cooling water can be controlled, thereby providing a basic guarantee for the uniform dispersion of the cooling water.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The electrolyte online mixing module uses continuous metering and mixing instead of the traditional intermittent stirring kettle, and merges multiple raw material inlet pipes into one into the static mixer. It can realize the rapid switching of different formulas and production capacities according to different proportions and flow rates, without the need to set up a special stirring kettle for mixing and stirring. In this way, stable and continuous production of electrolyte can be achieved, which can not only improve production efficiency, but also greatly reduce the volume of the entire device, save equipment installation space and investment costs, and reduce quality risks and safety risks. The small modular design can flexibly match different process and device requirements to adapt to different production environments. The module is equipped with an online quality detection analyzer (specific gravity, chromaticity, acidity, moisture), which can realize continuous monitoring of mixing quality. The module is equipped with online instruments for process conditions such as pressure, temperature, flow, etc., and remote fully automated one-button operation and real-time automatic adjustment are realized through PLC or DCS system;

[0017] 2. The electrolyte online mixing module improves the heat exchanger structure and can seal and open the arc groove on the diversion mechanism by adjusting the positions of the first sealing plug and the second sealing plug, thereby adjusting the initial position of the cooling water entering the heat exchanger, so that the cooling water can be evenly dispersed inside the heat exchanger, thereby improving the heat exchange effect;

[0018] 3. The electrolyte online mixing module can drive the water wheel to rotate through the action of cooling water, thereby driving the rotating shaft, circular plate and convex block to rotate. With the action of the ejector rod and the spring, the spoiler can stir the water flow inside the heat exchanger, which can increase the contact area and contact time between the water flow and the heat exchange tube, improve the heat exchange effect, and avoid the generation of bubbles due to excessive local water flow temperature, thereby ensuring the safe use of the device.

[0030] When using the electrolyte online mixing module, Figure 1 and Figure 2As shown, multiple feed pipes 2 are respectively connected to different raw material storage devices. When the electrolyte is produced, all the manual valves of the pipeline are first opened, and nitrogen is blown into the pipeline of the entire device through the nitrogen pipe 14. At this time, the gas in the pipeline is discharged to the outside through the air pipe 15, so as to avoid the influence of impurities in the air on the normal reaction of the device.

After the production of the electrolyte is completed, the feeding is stopped, and the manual valve of the nitrogen pipe 14 is opened again, and the nitrogen flushing operation is performed to realize the purging effect of the pipeline to avoid the corrosion of the pipeline by the residual material, thereby extending the service life of the equipment;

The rotating shaft 1001 is connected to the heat exchanger 9 by a bearing, and the water wheel 1002 is fixed on the rotating shaft 1001, and the water wheel 1002 is located directly above the water inlet 901; the rotating shaft 1001 is also evenly fixed with a circular plate 1003, and the circular plate 1003 is fixed with a convex block 1004 with an arc structure. 04; the spoiler 1005 is arranged in the heat exchanger 9, and the spoiler 1005 is slidably connected to the rotating shaft 1001, and a through hole is opened on the spoiler 1005, and a top rod 1006 is fixed on the spoiler 1005, and the top rod 1006 is slidably connected to the protrusion 1004; a sliding rod 1007 is also fixed on the spoiler 1005, and the sliding rod 1007 is slidably connected to the heat exchanger 9, and one end of a spring 1008 is also fixed on the sliding rod 1007, and The other end of the spring 1008 is fixed in the heat exchanger 9; the diversion mechanism 11 includes a diversion box 1101, a fixed plate 1102, a first cross bar 1103, a first sealing plug 1104, a second cross bar 1105 and a second sealing plug 1106, the diversion box 1101 is fixed in the heat exchanger 9, and an arc groove is provided on the diversion box 1101; the fixed plate 1102 is fixed on the left sliding bar 1007, and one end of the first cross bar 1103 is fixed on the fixed plate 1102, and the first cross bar 1103 is fixed on the left sliding bar 1007. The other end of 103 is fixed with a first sealing plug 1104, and the first sealing plug 1104 cooperates with the inner arc groove on the shunt box 1101 to achieve a sealing effect. The fixing plate 1102 is also fixed with one end of a second cross bar 1105, and the other end of the second cross bar 1105 is fixed with a second sealing plug 1106, and the second sealing plug 1106 cooperates with the outer arc groove on the shunt box 1101 to achieve a sealing effect. At the same time, the length of the second cross bar 1105 is greater than the length of the first cross bar 1103;

[0032] When the material in the heat exchange tube 905 is heat exchanged, Figure 1-Figure 7As shown, cooling water enters the diverter box 1101 through the water inlet 901. At this time, under the action of the water flow and in conjunction with the action of the water wheel 1002, the rotating shaft 1001, the circular plate 1003 and the protrusion 1004 can rotate. When the protrusion 1004 contacts and slides with the top rod 1006, the spoiler 1005 is forced to move. In conjunction with the sliding guide effect between the slide bar 1007 and the heat exchanger 9, the stability of the movement of the spoiler 1005 can be ensured. At this time, the spring 1008 is forced to contract. When the protrusion 1004 contacts and slides with the top rod 1006, the spoiler 1005 is forced to move. When the projection 1004 is separated from the top rod 1006, the spoiler 1005 can be reset under the elastic action of the spring 1008. According to the above principle, when the projection 1004 rotates, the spoiler 1005 can make orderly left and right reciprocating motions, and in combination with the through holes on the spoiler 1005, the turbulence of the cooling water in the heat exchanger 9 can be achieved, thereby increasing the contact area and contact time between the cooling water and the heat exchange tube 905, thereby effectively improving the heat exchange effect of the material in the heat exchange tube 905, and on the left When the side sliding bar 1007 slides, the fixed plate 1102 is moved at the same time, thereby driving the first cross bar 1103, the first sealing plug 1104, the second cross bar 1105 and the second sealing plug 1106 to move. When the fixed plate 1102 moves to the left, the first sealing plug 1104 is nested and sealed with the inner groove of the diverter box 1101, and the second sealing plug 1106 is separated from the outer groove of the diverter box 1101, so that the cooling water in the diverter box 1101 enters the heat exchange tube 905 through the outer groove. When the fixed plate 1102 moves to the right, the first sealing plug 1104 is separated from the inner groove of the diverter box 1101, and the second sealing plug 1106 is nested and sealed with the outer groove of the diverter box 1101, so that the cooling water in the diverter box 1101 enters the heat exchange tube 905 through the inner groove, thereby changing the inflow position of the cooling water, and then the cooling water can be more evenly dispersed in the heat exchange tube 905, and then the heat exchange effect can be further improved. The above is the working principle of the electrolyte online mixing module.
