Description

Technical Field

[0001] This utility model belongs to the field of cleaning agent preparation and delivery technology, and in particular relates to a photovoltaic cell cleaning agent preparation and delivery device. Background Technology

[0002] Photovoltaic cell cleaner is a cleaning agent specifically designed for cleaning the surface of photovoltaic panels and their components. It has excellent cleaning ability and can effectively remove various contaminants from the surface of photovoltaic panels, such as dust, oil, bird droppings, and scale, restoring and improving the light transmittance and power generation efficiency of photovoltaic panels.

[0003] During the production of photovoltaic cell cleaning agents, the mixed solution needs to be filtered to remove undissolved impurities. A thickener is added to the mixed solution to make it easier to adhere to the surface of the photovoltaic panel and less prone to runoff. However, this results in poor solution fluidity, slow filtration speed, and low filtration efficiency, thereby reducing the production rate of photovoltaic cell cleaning agents.

[0004] To address the aforementioned issues, this application proposes a photovoltaic cell cleaning agent preparation and delivery device. Utility Model Content

[0005] The purpose of this invention is to provide a photovoltaic cell cleaning agent preparation and delivery device, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a photovoltaic cell cleaning agent preparation and delivery device, comprising a mixing tank and an outlet pipe connected to its bottom, a metering cylinder located below the mixing tank with an inlet pipe at its top, and a filter pipe connected between the inlet pipe and the outlet pipe, wherein a filter element is installed inside the filter pipe, and a piston is installed inside the metering cylinder. When the piston moves downward, it can generate a negative pressure inside the metering cylinder to provide a downward driving force for the filtered solution, accelerating the solution to pass through the filter element. When the piston moves upward, it can discharge the solution from the metering cylinder. A liquid level sensor is installed at the top of the metering cylinder and electrically connected to an electromagnetic valve on the outer wall of the inlet pipe, which can control the closing of the electromagnetic valve to prevent the solution in the metering cylinder from mixing with the solution above when it is discharged.

[0008] Furthermore, an electric push rod for driving the piston movement is provided below the metering cylinder.

[0009] Furthermore, the upper end of the side wall of the metering cylinder is connected to a drain pipe, and the outer wall of the drain pipe is equipped with an electromagnetic valve to control the opening and closing of the drain pipe.

[0010] Furthermore, the top end of the inlet pipe and the bottom end of the filter pipe are connected by a flange.

[0011] Furthermore, the top end of the filter tube is connected to the bottom end of the outlet tube via a flange.

[0012] Furthermore, the liquid level sensor is electrically connected to the electric actuator, which can control the electric actuator to close.

[0013] This utility model has the following beneficial effects:

[0014] This invention creates negative pressure inside the metering cylinder by moving the piston downwards, which in turn drives the filtered solution downwards, accelerating the rate at which the solution passes through the filter element and thus speeding up the filtration process. This, in turn, increases the production rate of the photovoltaic cell cleaning agent. Moving the piston upwards promotes the outward discharge of the solution.

[0015] When discharging, the solution is discharged from the metering cylinder. The liquid level sensor monitors the liquid level in the metering cylinder in real time and sends an electrical signal to control the inlet pipe to close via an electromagnetic valve. After closing, the solution will slowly pass through the filter element, resulting in more thorough filtration. The solution discharged outward will not mix with the solution above, ensuring uniform filtration.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0024] 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.

[0025] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0026] Please see Figure 1-4 As shown, this utility model is a photovoltaic cell cleaning agent preparation and conveying device, including a mixing tank 1 and a liquid outlet pipe 101 connected to its bottom end, a metering cylinder 4 located below the mixing tank 1, with a liquid inlet pipe 3 at its top, and a filter pipe 2 connected between the liquid inlet pipe 3 and the liquid outlet pipe 101. A filter element 11 is installed in the filter pipe 2, and a piston 5 is installed in the metering cylinder 4. When the piston 5 moves downward, it can generate a negative pressure in the metering cylinder 4 to provide a downward driving force for the filtered solution, accelerating the solution to pass through the filter element 11. When the piston 5 moves upward, it can discharge the solution from the metering cylinder 4. A liquid level sensor 10 is installed at the top of the metering cylinder 4 and is electrically connected to an electromagnetic valve 7 on the outer wall of the liquid inlet pipe 3. It can control the closing of the electromagnetic valve 7 to prevent the solution in the metering cylinder 4 from mixing with the solution above when it is discharged.

[0027] This embodiment provides a photovoltaic cell cleaning agent preparation and conveying device. Raw materials are mixed in a mixing tank 1. The resulting solution is filtered through a filter element 11 to remove insoluble impurities. During filtration, the piston 5 moves downwards, creating a negative pressure inside the metering cylinder 4, which provides a downward force to the mixed solution. This accelerates the flow of the mixed solution through the filter element 11, increasing the filtration rate and thus improving the photovoltaic cell cleaning agent preparation rate. The piston 5 moves upwards, promoting solution discharge. A monitoring height is pre-set for the level sensor 10, which monitors the solution in the metering cylinder 4 in real time. When this height is reached, the level sensor 10 sends an electrical signal to close the solenoid valve 7, preventing the solution from mixing with the solution in the filter cylinder during discharge and ensuring filtration efficiency. Simultaneously, the level sensor 10 controls the solenoid valve 7 to control the volume of solution in the metering cylinder 4. During discharge, the piston 5 pushes the solution out of the metering cylinder 4, achieving quantitative discharge.

[0028] The metering cylinder 4 is equipped with an electric push rod 6 below it for driving the piston 5 to move. The piston 5 can be directly driven to move vertically by the electric push rod 6, which is simple to operate.

[0029] The upper end of the side wall of the metering cylinder 4 is connected to a drain pipe 8. The outer wall of the drain pipe 8 is equipped with an electromagnetic valve 9 to control the opening and closing of the drain pipe 8. When discharging, the piston 5 is moved upward by the electric push rod 6, which pushes the solution above the piston 5 upward, so that the solution enters the electromagnetic valve 9 and is discharged.

[0030] The top end of the liquid inlet pipe 3 is connected to the bottom end of the filter pipe 2 by a flange. The flange connection structure is simple, easy to connect, and can be disassembled, making it convenient to remove the metering cylinder 4 for cleaning and maintenance later.

[0031] The top end of the filter tube 2 is connected to the bottom end of the liquid outlet tube 101 by a flange. Both the top and bottom ends of the filter tube 2 are equipped with flanges, so that the filter tube 2 can be disassembled for replacement and cleaning.

[0032] The liquid level sensor 10 is electrically connected to the electric push rod 6 and can control the electric push rod 6 to close. After the liquid level in the metering cylinder 4 reaches the preset value of the liquid level sensor 10, the liquid level sensor 10 controls the electric push rod 6 and the solenoid valve 7 to close synchronously.

[0033] Understandably, this invention can accelerate the filtration rate of the solution, increase the preparation rate of the photovoltaic cell cleaning agent, and prevent the solution being discharged from mixing with the filtered solution, thus ensuring uniform filtration effect.

[0034] A specific application of the operation process in this embodiment is as follows: The solution is mixed and stirred in the mixing tank 1. The mixed solution enters the filter tube 2 through the outlet pipe 101 from the mixing tank 1. The filter tube 2 is equipped with a filter element 11 to filter the solution and remove insoluble impurities. During filtration, the first electromagnetic valve 7 is opened and the second electromagnetic valve 9 is closed. The electric push rod 6 drives the piston 5 to move downward, and a negative pressure is generated in the metering cylinder 4, which makes the filtered solution feel suction, accelerates the solution to pass through the filter element 11, and improves the filtration speed. The liquid level sensor 10 monitors the liquid level in the metering cylinder 4 in real time. After the preset value of the metering cylinder 4 is reached, the sensor sends an electrical signal to control the electric push rod 6 and the first electromagnetic valve 7 to close, controlling the amount of solution entering the metering cylinder 4. The second electromagnetic valve 9 is opened, driving the electric push rod 6 to move the piston 5 upward and send the solution in the metering cylinder 4 into the drain pipe 8, completing the quantitative discharge of the solution.
