Technical Field

[0001] This utility model relates to the field of capacitor processing equipment technology, and more specifically, to a capacitor electrolyte filling device. Background Technology

[0002] Electrolyte is the medium used in capacitor products. It provides ion channels for the normal operation of the positive and negative electrodes. There are various methods to fill the capacitor with electrolyte, among which direct filling is a relatively common technique. In the electrolyte filling process, the deviation in the filling amount will directly affect the performance and quality of the capacitor. Therefore, enterprises need to design a device that can quantitatively fill electrolyte to meet the needs of experiments and production. Utility Model Content

[0003] The purpose of this invention is to address the needs of the prior art and provide a filling device for capacitor electrolyte. This invention is designed with a filling device to perform the filling operation of electrolyte. The filling device has a second liquid chamber with a fixed capacity. When filling electrolyte, only the second liquid chamber is connected to the liquid outlet pipe to achieve the purpose of quantitative output of electrolyte. This invention can well meet the needs of laboratory and industrial applications.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A capacitor electrolyte filling device includes a support, a storage tank, and a filling device. The storage tank is vertically installed on the side of the support, and the filling device is connected to the bottom of the side wall of the storage tank. A control element is installed inside the filling device, and a liquid outlet pipe is connected to the bottom of the filling device. The control element controls whether the filling device is connected to the storage tank and whether the liquid outlet pipe is opened to output electrolyte. A platform is installed directly below the liquid outlet pipe.

[0006] Furthermore, the filling device includes a tube body, a base sealed at the bottom of the tube body, a partition plate connected and installed inside the tube body, which divides the inside of the tube body into a first liquid chamber and a second liquid chamber. An inlet pipe interface is connected to the side wall of the tube body. One end of the inlet pipe interface is connected to the first liquid chamber, and the other end is connected to a storage tank. The partition plate has a second through hole, and the base has a first through hole. The opening and closing of the first and second through holes are controlled by the control element. The outlet pipe is threaded to the base and connected to the first through hole.

[0007] Furthermore, the first through hole and the second through hole are not opened simultaneously.

[0008] Furthermore, the control element includes a control push cylinder and a connecting rod. The control push cylinder is installed on the top of the outer side of the tube body, and the connecting rod is installed vertically inside the tube body. The top end of the connecting rod is connected to the piston rod end of the control push cylinder, and the bottom end of the connecting rod extends to the second liquid chamber. A first sealing plug and a second sealing plug are fixedly connected to the outer wall of the connecting rod. Both the first sealing plug and the second sealing plug are located in the second liquid chamber.

[0009] Furthermore, the distance between the first sealing plug and the second sealing plug is less than the distance between the partition plate and the base.

[0010] Furthermore, both the first and second sealing plugs have a tapered shape, and the first and second sealing plugs are installed facing away from each other.

[0011] Furthermore, a horizontal seat is fixedly connected to the side of the bracket, and the liquid storage tank is installed vertically through the horizontal seat. A lifting cylinder is installed below the liquid storage tank, and the piston rod end of the lifting cylinder is connected to the bottom of the liquid storage tank. A replenishment pipe interface is installed on the top of the liquid storage tank.

[0012] Furthermore, a stroke control mechanism is installed on the side of the bracket. The stroke control mechanism includes a limit frame and a switch. The side of the limit frame is bolted to the bracket. The top surface of the limit frame blocks the descent path of the liquid storage tank. The switch is installed on the top surface of the limit frame, and the switch circuit is connected to the control element.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figure 1 The illustrated capacitor electrolyte filling device includes a support 1, a storage tank 2, and a filling device 3. The storage tank 2 stores the electrolyte to be filled and is vertically installed on the side of the support 1, which stabilizes the storage tank 2. The filling device 3 is connected to the bottom of the side wall of the storage tank 2 and is connected to the storage tank 2 via a pipeline. A control element 4 is installed inside the filling device 3, and a liquid outlet pipe 5 is connected to the bottom of the filling device 3. The control element 4 controls whether the filling device 3 is connected to the storage tank 2 and whether the liquid outlet pipe 5 is opened to output electrolyte. When the filling device 3 is not dispensing liquid, it needs to be connected to the storage tank 2 to replenish the electrolyte inside the filling device 3. When the filling device 3 is dispensing liquid, the connection between the filling device 3 and the storage tank 2 is cut off. At this time, the electrolyte output from the dispensing pipe 5 is the liquid stored inside the filling device 3. This design can form a quantitative output effect of electrolyte to meet production needs (the filling volume error can be controlled within 1%). In this utility model, a platform 12 is installed directly below the dispensing pipe 5. The platform 12 is used to place the cylindrical metal container shell of the capacitor. The top of the cylindrical metal container of the capacitor is open to facilitate injection filling.

[0021] like Figure 2As shown, the filling device 3 includes a tube body 31, with the upper end of the tube body 31 closed and a base 32 sealed at the bottom. The base 32 is assembled last to facilitate the pre-installation of internal parts of the tube body 31. The base 32 can be sealed by welding or threaded connection. A partition plate 33 is installed inside the tube body 31, dividing the interior of the tube body 31 into a first liquid chamber 311 and a second liquid chamber 312. An inlet pipe interface 34 is connected to the side wall of the tube body 31. 4. One end of the pipe is connected to the first liquid chamber 311, and the other end is connected to the storage tank 2. The inlet pipe interface 34 is always connected to the storage tank 2, so the electrolyte in the storage tank 2 is continuously replenished to the first liquid chamber 311. The partition plate 33 has a second through hole 331, which connects the first liquid chamber 311 and the second liquid chamber 312. When the second through hole 331 is open, the electrolyte in the first liquid chamber 311 enters the second liquid chamber 312. The electrolyte in the second liquid chamber 312 is the final output electrolyte. Because the capacity of the second liquid chamber 312 is fixed, the electrolyte can be quantitatively output. The base 32 has a first through hole 321, and the outlet pipe 5 is threaded to the base 32 and connected to the first through hole 321. When the first through hole 321 is open, the electrolyte in the second liquid chamber 312 is output through the outlet pipe 5. This invention uses a control element 4 to control the opening and closing of the first through hole 321 and the second through hole 331. 1. They do not open simultaneously. That is, when the second through hole 331 is open, the first through hole 321 is closed. At this time, it is used for replenishing electrolyte in the second liquid chamber 312. When the first through hole 321 is open, the second through hole 331 is closed. The closure of the second through hole 331 prevents the electrolyte in the first liquid chamber 311 from entering the second liquid chamber 312. At this time, the electrolyte output from the liquid outlet fitting 5 is the stored electrolyte in the second liquid chamber 312. This stored electrolyte is fixed, so a quantitative output effect can be achieved.

[0022] like Figure 2As shown, the control element 4 includes a control cylinder 41 and a connecting rod 42. The control cylinder 41 is installed on the top of the outer side of the tube body 31, and the connecting rod 42 is installed vertically inside the tube body 31. The top end of the connecting rod 42 is connected to the piston rod end of the control cylinder 41, and the bottom end of the connecting rod 42 extends to the second liquid chamber 312. A first sealing plug 43 and a second sealing plug 44 are fixedly connected to the outer wall of the connecting rod 42. Both the first sealing plug 43 and the second sealing plug 44 are located in the second liquid chamber 312. The extension and retraction of the piston rod of the control cylinder 41 drives the connecting rod 42 to rise and fall, and the first sealing plug 43 and the second sealing plug 44 rise and fall together. The new design places the gap between the first sealing plug 43 and the second sealing plug 44 smaller than the gap between the partition plate 33 and the base 32. This results in only one sealing plug forming a through hole sealing effect during the lifting and lowering movement of the first sealing plug 43 and the second sealing plug 44, thus meeting the design requirement that the first through hole 321 and the second through hole 331 do not open at the same time. In this utility model, both the first sealing plug 43 and the second sealing plug 44 adopt a tapered shape and are installed in a back-to-back manner. The tapered sealing plug has a good sealing effect and can prevent leakage.

[0023] It is more effective to fill the capacitor by bringing the outlet fitting 5 close to the cylindrical metal container of the capacitor. This prevents the electrolyte from splashing out. For this reason, ... Figure 1As shown, this utility model has a horizontal seat 11 fixedly connected to the side of the bracket 1. The liquid storage tank 2 is installed vertically through the horizontal seat 11. A lifting cylinder 6 is installed below the liquid storage tank 2, with the lifting cylinder 6 installed vertically upwards. The piston rod end of the lifting cylinder 6 is connected to the bottom of the liquid storage tank 2. The lifting and lowering of the liquid storage tank 2 is achieved by the extension and retraction of the piston rod of the lifting cylinder 6. The horizontal seat 11 serves to guide the lifting and lowering movement of the liquid storage tank 2. To prevent excessive descent, this utility model has a stroke control mechanism 7 installed on the side of the bracket 1. The stroke control mechanism 7 includes a limit frame 71 and a switch 72. The limit frame 71 is fixedly connected to the bracket 1 with side bolts. The top surface of the limit frame 71 blocks the descent path of the liquid storage tank 2, thus limiting the descent of the liquid storage tank 2 and controlling the approach position of the liquid outlet pipe 5. The limit frame 71 can be adjusted in the height direction of the bracket 1 (e.g., on the side of the bracket 1). (A long groove is provided for installing bolts) to accommodate different feed height requirements. This utility model stipulates that the electrolyte output is not allowed to be opened when the liquid outlet fitting 5 is not lowered to the feed position. To address this, this utility model designs a switch 72 installed on the top surface of the limit frame 71. The switch 72 is a contact-pressing type switch and is semi-embedded. The switch 72 can be retracted into the top surface of the limit frame 71 when pressed. The switch 72 is connected to the control element 4, specifically to the control push cylinder 41 of the filling device 3. The liquid outlet function of the filling device 3 can only be opened after the switch 72 is triggered. The liquid outlet operation is generally set to more than 10 seconds to ensure that the electrolyte flows out smoothly and completely. After the liquid outlet operation is completed, the storage tank 2 rises as a whole. After the switch 72 is reset, it controls the filling device 3 to reset. When the filling device 3 is reset, the first liquid chamber 311 and the second liquid chamber 312 are connected, and the liquid outlet fitting 5 is closed. At this time, the second liquid chamber 312 is replenished with electrolyte.

[0024] This invention can be used for laboratory sample preparation and can also be applied industrially. In industrial applications, the platform 12 can be replaced with a conveyor belt to continuously rotate the cylindrical metal container of the capacitor for filling operations. The liquid level control element is installed inside the liquid storage tank 2, and a replenishment pipe interface 21 is installed on the top of the liquid storage tank 2. When the liquid level in the liquid storage tank 2 drops too much, electrolyte can be replenished in time through the replenishment pipe interface 21.

[0025] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
