Description

Technical Field

[0001] This utility model relates to the field of battery production technology, specifically to an adjustable volume feeding device. Background Technology

[0002] Vanadium redox flow batteries (VRBs) are a key technology for large-capacity energy storage power stations and are currently the most widely researched and applied flow battery technology. Unlike lithium batteries used in small applications such as mobile phones, computers, and automobiles, VRBs offer ultra-large capacity and ultra-long charge-discharge times, are safe and reliable, and have virtually unlimited cycle life, thus earning them the reputation of "electricity banks." They are primarily used in building energy storage power stations, replacing generators, and serving as backup power sources.

[0003] The working principle of vanadium battery charging and discharging is to use vanadium ion solutions with different valence states as the active materials for the positive and negative electrodes, respectively, and store them in their respective energy liquid (electrolyte) tanks. During the charging and discharging test of the battery, the energy liquid (electrolyte) is circulated from the external storage tank through the positive and negative electrode chambers of the battery by a pump, and oxidation and reduction reactions occur on the electrode surfaces to realize the charging and discharging of the battery.

[0004] In the electrolyte preparation process, various solutions need to be mixed according to their respective predetermined volumes. However, in existing technologies, the volume of each solution is a predetermined value, resulting in poor measurement accuracy. Furthermore, a large amount of solution may adhere to the sidewalls of the intermediate pipes. Therefore, accurately measuring the solution volume and reducing solution adhesion are urgent problems that need to be solved. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention aims to provide an adjustable volume feeding device. This solution can accurately measure the volume of the solution and reduce the adhesion of the solution.

[0006] This utility model is achieved through the following technical solution:

[0007] An adjustable volume feeding device includes a feeding assembly, the feeding assembly comprising:

[0008] The discharge pipe has a weighing platform enclosed at its upper inlet.

[0009] A measuring hopper is fixed to the weighing platform; the weighing platform has through holes that communicate with both the measuring hopper and the inside of the discharge pipe; the upper inlet of the discharge pipe is also provided with an opening and closing component for closing or opening the through holes.

[0010] A vibratory motor is fixed to an external support, and the output end of the vibratory motor is fixedly connected to the side wall of the discharge pipe.

[0011] Compared to existing technologies, which suffer from poor measurement accuracy due to fixed volumes for each solution and the potential for significant solution adhesion to the sidewalls of intermediate pipes, this invention provides an adjustable volume feeding device. This solution allows for precise measurement of solution volume and reduces solution adhesion. Specifically, the device includes a feeding assembly comprising, from bottom to top, a discharge pipe, a weighing platform, and a measuring hopper. The weighing platform is fixed and seals the upper end of the discharge pipe. The measuring hopper is placed on the weighing platform, and by measuring the weight of the measuring hopper, the volume of the solution inside can be accurately calculated. A through-hole is located at the center of the weighing platform and is sealed by an opening / closing component. When the weighing platform reaches the desired weight, the opening / closing component is activated, allowing the solution inside the measuring hopper to flow through the through-hole into the discharge pipe and fall into a mixing tank below to mix with other solutions to prepare the electrolyte. Secondly, a vibration motor is also provided. The output end of the vibration motor is used to drive the discharge pipe to vibrate. At this time, the weighing platform and the metering hopper above vibrate accordingly, thereby shaking off a large amount of solution adhering to the inner wall of the metering hopper and dripping it down through the through hole, so as to reduce the adhesion of the solution during the transportation process and improve the preparation efficiency. In addition, when the through hole is closed, the solution at the through hole can be used as an error to measure in advance.

[0012] Further optimized, as a specific structure of an opening and closing component, the side wall of the upper opening of the discharge pipe has a through groove, and a sliding rod is slidably connected to the through groove. The end of the sliding rod that extends into the discharge pipe has a closed head.

[0013] A driving component is fixed to the outside of the discharge pipe. The driving component and the sliding rod are connected at one end outside the discharge pipe, and the driving component is used to drive the sliding rod to slide radially along the discharge pipe, thereby causing the sealing head to close or open the through hole. In this design, a sliding rod is provided, and the sliding rod and the through groove are slidably connected. Thus, under the drive of the driving component, the sliding rod can be moved along the discharge pipe to allow the sealing head to close or open the through hole. In addition, a sliding sleeve is fixed on the upper side of the discharge pipe, and the sliding rod passes through the sliding sleeve and is slidably connected to ensure stable sliding of the sliding rod.

[0014] To further optimize the system and improve the sealing performance of the through hole and prevent solution leakage when the through hole is closed, the lower end of the through hole has a downward protrusion, the lower end of the through hole passes through the lower end of the protrusion, and the side of the protrusion facing the through groove is a guide surface.

[0015] The upper side of the sealing head has a rubber layer, and the upper surface of the rubber layer is higher than the lower end of the protrusion. In this design, the upper side of the sealing head has a rubber layer. When the slide rod slides towards the protrusion, the rubber layer is gradually compressed under the action of the guide surface until the rubber layer is located at the lower end of the protrusion. At this time, the lower end of the protrusion is embedded in the rubber layer to achieve a seal.

[0016] To further optimize the process and prevent the solution from sticking to the rubber layer, a non-stick adhesive is applied to the surface of the rubber layer.

[0017] As a redundancy solution, the drive component is a telescopic cylinder.

[0018] As a further optimization, as a detachable connection method, a clamp is provided on the output end of the vibration motor, and the clamp is tightly wrapped around the discharge pipe.

[0019] To further optimize the process and facilitate the addition of solution to the metering hopper, the feeding assembly also includes an output pipe. The outlet of the output pipe is located above the metering hopper and is used to output liquid into the metering hopper. A solenoid valve is provided at the outlet of the output pipe.

[0020] To further optimize the process and determine the initial amount of solution to be input into the metering hopper, the feeding assembly also includes a control system for controlling the liquid flow rate output by the solenoid valve.

[0021] To further optimize the weighing platform and facilitate verification of its output values, the side wall of the measuring hopper is equipped with a scale for detecting the internal liquid volume.

[0022] To further optimize the process and facilitate the simultaneous addition of multiple required solutions to the mixing tank, a mixing tank is also included. The mixing tank has several feeding components on its top, and the lower end of the discharge pipe in each feeding component is used to output liquid into the mixing tank.

[0023] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0024] This invention provides an adjustable volume feeding device. Using this solution, the volume of the solution can be accurately measured by a weighing platform, and the adhesion of the solution can be reduced by a vibration motor. Attached Figure Description

[0035] The discharge pipe 1 has a weighing platform 2 enclosed at its upper inlet.

[0036] Measuring hopper 3 is fixed on the weighing platform 2; the weighing platform 2 has through holes 201 that communicate with the inside of the measuring hopper 3 and the discharge pipe 1 respectively; the upper inlet of the discharge pipe 1 is also provided with an opening and closing component for closing or opening the through holes 201.

[0037] Vibration motor 4 is fixed to an external support, and the output end of vibration motor 4 is fixedly connected to the side wall of discharge pipe 1.

[0038] Compared to existing technologies, which suffer from poor measurement accuracy due to fixed volumes for each solution and the potential for significant solution adhesion to the sidewalls of intermediate pipes, this invention provides an adjustable volume feeding device. This solution allows for precise measurement of solution volume and reduces solution adhesion. Specifically, the device includes a feeding assembly comprising, from bottom to top, a discharge pipe 1, a weighing platform 2, and a measuring hopper 3. The weighing platform 2 fixes and seals the upper end of the discharge pipe 1. The measuring hopper 3 is placed on the weighing platform 2. By measuring the weight of the measuring hopper 3 using the weighing platform 2, the volume of the solution inside the measuring hopper 3 can be accurately calculated. A through-hole 201 is located at the center of the weighing platform 2 and is closed by an opening / closing assembly. When the weight on the weighing platform 2 reaches the desired level, the opening / closing assembly is activated, allowing the solution inside the measuring hopper 3 to flow through the through-hole 201 into the discharge pipe 1 and fall into the mixing tank below to mix with other solutions to prepare the electrolyte. Secondly, a vibration motor 4 is also provided. The output end of the vibration motor 4 is used to drive the discharge pipe 1 to vibrate. At this time, the weighing platform 2 and the metering hopper 3 above vibrate accordingly, thereby shaking off a large amount of solution adhering to the inner wall of the metering hopper 3 and dripping it down through the through hole 201 to reduce the adhesion of the solution during the transportation process and improve the preparation efficiency. In addition, when the through hole 201 is closed, the solution at the through hole 201 can be used as an error to measure in advance.

In this solution, a slide rod 101 is provided, and the slide rod 101 and the through groove are slidably connected. In this way, under the drive of the driving component, the slide rod 101 can be moved along the discharge pipe 1 so that the sealing head 102 can close or open the through hole 201.

In this design, the upper surface of the sealing head 102 is covered with a rubber layer 103. When the slide rod 101 slides toward the protrusion 202, the rubber layer 103 is gradually compressed under the action of the guide surface until the rubber layer 103 is located at the lower end of the protrusion 202. At this time, the lower end of the protrusion 202 is embedded in the rubber layer 103 to achieve a seal.

[0043] In some embodiments, to prevent the solution from sticking to the rubber layer 103, a non-stick adhesive is attached to the surface of the rubber layer 103.
