Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of solution filling, in particular to a solution filling device. Background Art
[0002] In the fields of fine chemicals, electronic packaging and new energy, high-precision filling of solutions such as ink, silica gel, lithium battery slurry, hydrogen fuel cell slurry, etc. is often involved. Traditional high-precision filling generally adopts manual weighing and adding. The operator places an empty beaker on the electronic platform scale, and then pours the required solution from the large solvent barrel into the beaker. When the solution in the beaker reaches the required weight, the solution in the beaker is manually poured into the corresponding production equipment.
[0003] However, there are many inconveniences in the manual weighing and adding method. On the one hand, the accuracy and consistency of manual weighing are poor, and there is a risk of dripping and overflowing of the solution during the transfer process. Moreover, after the solution is poured into the production equipment, there will be a certain amount of wall residue on the beaker. On the other hand, some solutions are flammable and explosive and have strong volatility, which can easily spread outward during the operation process and cause pollution to the production environment. Utility Model Content
[0004] Based on this, it is necessary to provide a solution filling device that can automatically achieve high-precision solution filling in order to solve the above problems.

[0008] a discharge pipeline and a return pipeline connected to one end of the main delivery pipeline away from the liquid storage tank, wherein the discharge pipeline is provided with a discharge control valve, and the return pipeline is provided with a return control valve; and
[0009] The controller is communicatively connected with the delivery pump and the flow meter. The flow meter can send the collected flow data to the controller. The controller can output a shutoff signal to the delivery pump after the flow data reaches a set value.

[0012] In one embodiment, the controller is capable of controlling the on and off of the main control valve, the discharge control valve and the reflux control valve.
[0013] In one embodiment, the main control valve, the discharge control valve and the reflux control valve are all pneumatic valves, and the controller includes a pneumatic component connected to the main control valve, the discharge control valve and the reflux control valve. The controller adjusts the on and off of the main control valve, the discharge control valve and the reflux control valve by controlling the gas flow direction of the pneumatic component.
[0014] In one of the embodiments, a discharge back pressure valve is provided on the discharge pipeline.
[0015] In one embodiment, the end of the reflux line is connected to the liquid storage tank.
[0016] In one of the embodiments, a reflux back-pressure valve is provided on the reflux pipeline.
[0017] In one of the embodiments, two reflux control valves are arranged on the reflux pipeline, wherein one of the reflux control valves is arranged at one end of the reflux pipeline close to the main delivery pipeline, and the other reflux control valve is arranged at the other end of the reflux pipeline, and the reflux back pressure valve is located between the two reflux control valves.

Before filling, open the main control valve and the reflux control valve and close the discharge control valve, and then start the delivery pump until the solution fills all the pipelines. Next, open the main control valve and the discharge control valve and close the reflux control valve, and then start the delivery pump to inject the solvent in the storage tank into the production equipment through the discharge pipeline. After the flow data detected by the flow meter reaches the set value, the controller can turn off the delivery pump to stop filling, without manual weighing and adding. Moreover, since the space in each pipeline is filled in advance, the flow data detected by the flow meter can be infinitely close to the actual filling amount of the solution. Therefore, the above-mentioned solution filling device can automatically achieve high-precision filling of the solution. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] See also Figure 1 , Figure 2 and Figure 3 The solution filling device 10 in the preferred embodiment of the utility model includes a base 100, a main conveying pipeline 200, a discharge pipeline 300, a reflux pipeline 400 and a controller 500.
[0031] The base 100 plays a supporting role, and the main conveying pipeline 200, the discharge pipeline 300, the return pipeline 400 and the controller 500 are all arranged on the base 100. In addition, a liquid storage tank 110 is arranged on the base 100, and the liquid storage tank 110 is used to contain the solution required for production, such as ink, electrolyte, etc. The liquid storage tank 110 includes a tank body and a tank cover, which can provide a relatively closed environment for the solution to prevent the solution from volatilizing.
[0032] In addition, a plurality of detachable legs 111 are installed at the bottom of the tank body of the liquid storage tank 110, and a foot 112 is installed at the bottom of the leg 111, and the liquid storage tank 110 is supported on the base 100 by the foot 112. The foot 112 is used to adjust the height of the liquid storage tank 110 and can level the liquid storage tank 110.
[0033] In this embodiment, the base 100 includes an armrest 120, and a roller assembly 130 is provided at the bottom of the base 100. The armrest 120 is convenient for the operator to hold, so as to push the base 100, and the roller assembly 130 can reduce the friction between the base 100 and the ground during the movement, so as to facilitate the solution filling device 10 to move from any position to the vicinity of the production equipment that needs to be filled with solution.
[0034] The main delivery pipeline 200 is connected to the liquid storage tank 110. Among them, the main delivery pipeline 200 is provided with a delivery pump 210, a main control valve 220 and a flow meter 230. The delivery pump 210 can be a screw pump, a peristaltic pump, etc., and the main control valve 220 can be a pneumatic valve, a solenoid valve or a mechanical valve. When the main control valve 220 is opened, the delivery pump 210 is started to pump the solution in the liquid storage tank 110 into the main delivery pipeline 200, and the flow meter 230 can detect the flow rate of the solution flowing through the main delivery pipeline 200. Specifically, the flow meter 230 can be a mass flow meter, and the flow data collected by it is a mass flow rate. Moreover, the mass flow rate is not affected by factors such as pressure and temperature, and has high accuracy and consistency.
[0035] Of course, if the solution injected into the production equipment needs to be measured in volume, the flow meter 230 can also be a volume flow meter.
[0036] Specifically, the delivery pump 210, the main control valve 220 and the flow meter 230 are connected in sequence, that is, the main control valve 220 is located between the delivery pump 210 and the flow meter 230, and the main control valve 220 and the flow meter 230 can be connected through a hard pipe. The base 100 includes a first bracket 140 and a second bracket 150, the delivery pump 210 can be installed on the first bracket 140, and the main control valve 220 and the flow meter 230 can be installed on the second bracket 150.
[0037] In this embodiment, a pressure sensor 240 is provided at the discharge end of the delivery pump 210, and the pressure sensor 240 can collect the real-time pressure value of the discharge end of the delivery pump 210. According to the real-time pressure value, it can be determined whether the flow of the solution in the main delivery pipeline 200 is stable.
[0038] Specifically, the discharge end of the conveying pump 210 can be provided with a reducer (not marked in the figure) and a tee (not marked in the figure) connected to the reducer, the pressure sensor 240 is connected to one outlet of the tee and installed on the first bracket 140, and the main control valve 220 is connected to the other outlet of the tee.
[0039] In addition, in this embodiment, a main control valve 600 is provided between the main delivery pipeline 200 and the liquid storage tank 110. The main control valve 600 may be a manual ball valve that can be opened and closed manually. When the main control valve 600 is closed, the liquid storage tank 110 is disconnected from the main delivery pipeline 200, making it convenient to maintain the main delivery pipeline 200.
[0040] The discharge pipeline 300 and the reflux pipeline 400 are both connected to the end of the main delivery pipeline 200 away from the liquid storage tank 110. Specifically, another tee (not shown) is installed at the end of the main delivery pipeline 200, and the discharge pipeline 300 and the reflux pipeline 400 are respectively connected to the two outlets of the tee. Further, a discharge control valve 310 is provided on the discharge pipeline 300, and a reflux control valve 410 is provided on the reflux pipeline 400. Both the discharge control valve 310 and the reflux control valve 410 can be pneumatic valves, solenoid valves or mechanical valves.
[0041] When the discharge control valve 310 is opened, the discharge pipeline 300 is opened; when the return control valve 410 is opened, the return pipeline 400 is opened. The discharge control valve 310 and the return control valve 410 can be controlled separately, so that the discharge pipeline 300 and the return pipeline 400 can be opened or closed separately.
[0042] The discharge pipeline 300 is used to communicate with the production equipment, and the solution can be injected into the production equipment through the discharge pipeline 300. Specifically in this embodiment, a discharge back pressure valve 320 is provided on the discharge pipeline 300. The discharge back pressure valve 320 can prevent the solution from flowing back and maintain a constant pressure in the discharge direction, thereby facilitating the smooth injection of the solution.
[0043] The reflux pipeline 400 is used to realize reflux exhaust, and the air in the pipelines of the solution filling device 10 can be discharged through the reflux pipeline 400. Specifically in this embodiment, a reflux back pressure valve 420 is provided on the reflux pipeline 400. Similarly, the reflux back pressure valve 420 can also prevent reflux and maintain a certain exhaust pressure.
[0044] In addition, in this embodiment, two reflux control valves 410 are provided on the reflux pipeline 400, one of which is provided at one end of the reflux pipeline 400 close to the main delivery pipeline 200, and the other reflux control valve 410 is provided at the other end of the reflux pipeline 400, and the reflux back pressure valve 420 is located between the two reflux control valves 410. A third bracket 160 is also provided on the base 100, and the reflux control valve 410 and the reflux back pressure valve 420 close to the main delivery pipeline 200 can be installed on the second bracket 150, and the pipeline between the two reflux control valves 410 can be supported by the third bracket 300.
[0045] The controller 500 may include a touch screen or physical buttons for human-computer interaction, so as to facilitate the operator to input the set value of filling, and also facilitate the operator to input control instructions such as start and stop, and the controller 500 can generate a control signal according to the control instruction. Among them, the controller 500 is connected to the delivery pump 210 and the flow meter 230 for communication, and the flow meter 230 can send the collected flow data to the controller 500, and the controller 500 can output a shut-off signal to the delivery pump 210 after the flow data reaches the set value.
[0046] Specifically, the set value is the amount of solution required for a single injection, and the flow data represents the cumulative flow of the solution flowing through the main delivery pipeline 200 within a preset time period. The controller 500 can compare the flow data with the set value, and if the flow data reaches the set value, it can output a shutoff signal to the delivery pump 210 to shut down the delivery pump 210, and the shutoff signal can be a high level signal.
[0047] When filling the solution, first connect the discharge pipeline 300 to the feed port of the corresponding production equipment; then, open the main control valve 220 and the discharge control valve 310 and close the reflux control valve 410, and then start the delivery pump 210 to inject the solvent in the liquid storage tank 110 into the production equipment through the discharge pipeline 300. When the flow data detected by the flow meter 230 reaches the set value, it means that the solution filling amount meets the demand, and the controller 500 can turn off the delivery pump 210 to stop filling. The filling process does not require manual weighing and adding, and the solution can be automatically filled, which can save labor, improve filling efficiency and avoid solution overflow and volatilization.
[0048] Moreover, the data of each filling can be automatically recorded by the controller 500, thereby improving the traceability of each filling batch and realizing humanized and intelligent production.
[0049] Furthermore, before the formal filling, it is necessary to perform a reflux exhaust operation. First, open the main control valve 220 and the reflux control valve 410 and close the discharge control valve 310, then start the delivery pump 210 until the solution fills all the pipes, and the air in the pipes is discharged from the reflux line 400. At this time, all the pipes are filled with solution and there is no extra space. Therefore, when formally filling, no additional solution is needed to fill the pipe, so the flow data detected by the flow meter 230 can be infinitely close to the actual filling amount of the solution, thereby ensuring the accuracy of automatic filling of the solution.
[0050] In this embodiment, the controller 500 can control the main control valve 220, the discharge control valve 310 and the return control valve 410 to be on and off.
[0051] The controller 500 can control the opening and closing of each valve according to the control instructions input by the operator, and can also automatically switch the valve switch state according to the pre-set program. For example, when the operator starts the filling with one button, the controller 500 first controls the opening of the main control valve 220 and the reflux control valve 410 and closes the discharge control valve 310, and then starts the delivery pump 210 for reflux exhaust; after detecting that the state of the solution filling device 10 is stable, the main control valve 220 and the discharge control valve 310 are controlled to open and the reflux control valve 410 is closed, and then the delivery pump 210 is started to officially start the filling.
[0052] Specifically, the pressure sensor 240 is connected to the controller 500 for communication and can send a real-time pressure value to the controller 500. During the reflux exhaust process, the control valve 410 can determine whether the solution filling device 10 has entered a stable state according to the real-time pressure value of the pressure sensor 240 and the real-time flow rate of the flow meter 230. When the above-mentioned real-time pressure value and real-time flow rate are both stable, it means that the filling device 10 has also reached stability.
[0053] Further, in this embodiment, the main control valve 220, the discharge control valve 310 and the reflux control valve 410 are all pneumatic valves, and the controller 500 includes a pneumatic assembly 510 connected to the main control valve 220, the discharge control valve 310 and the reflux control valve 410. The controller 500 adjusts the on-off of the main control valve 220, the discharge control valve 310 and the reflux control valve 410 by controlling the gas flow direction of the pneumatic assembly 510. The opening and closing speed of the pneumatic valve is fast, so that high-frequency switching and precise flow control can be achieved.
[0054] In addition, in this embodiment, the end of the reflux pipeline 400 is connected to the liquid storage tank 110. During the reflux exhaust process, part of the solution will enter the reflux pipeline 400 and be discharged from the end of the reflux pipeline 400. Therefore, by connecting the end of the reflux pipeline 400 to the liquid storage tank 110, the part of the solution can be refluxed into the liquid storage tank 110, thereby avoiding the waste of solution.
[0055] When the above-mentioned solution filling device 10 is used, the discharge pipeline 300 is first connected to the feed port of the corresponding production equipment. Before filling, the main control valve 220 and the reflux control valve 410 are opened and the discharge control valve 310 is closed, and then the delivery pump 210 is started until the solution fills the pipelines at various locations. Next, the main control valve 220 and the discharge control valve 310 are opened and the reflux control valve 410 is closed, and then the delivery pump 210 is started to inject the solvent in the liquid storage tank 110 into the production equipment through the discharge pipeline 300. After the flow data detected by the flow meter 230 reaches the set value, the controller 500 can turn off the delivery pump 210 to stop filling, without manual weighing and adding. Moreover, since the space in each pipeline is filled in advance, the flow data detected by the flow meter 230 can be infinitely close to the actual discharge filling amount of the solution. Therefore, the above-mentioned solution filling device 10 can automatically realize high-precision filling of the solution.
[0056] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0057] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
