Description

Technical Field

[0001] This utility model belongs to the technical field of glass processing equipment, and more specifically, it relates to a device for controlling the pH of a glass processing cleaning tank. Background Technology

[0002] Currently, in the touchscreen manufacturing field, AG glass (full Chinese name: anti-reflective glass, English name: Anti-glare glass) is produced in two forms: a spray-type horizontal line and an immersion-type tank line. In the immersion-type tank line, the acid value of the water increases significantly after acid etching and rinsing, making the water weakly acidic, which affects product quality. Diluting with water wastes water resources and increases wastewater treatment costs. In existing AG glass manufacturing processes using immersion-type tank lines, the acid carried into the tank during the rinsing process after acid etching increases the acid value of the tank. With continuous production, the acid concentration gradually increases, significantly impacting product quality. Diluting with water is generally used, but this consumes a large amount of water and generates a large amount of wastewater, resulting in high wastewater treatment costs. This not only wastes water resources but also increases production costs due to wastewater treatment.

[0003] Existing technology includes a device titled "A Self-Cleaning Device for Acidity and Alkalinity Detection," with publication number CN106198688A. This device comprises a mounting housing, an acidity / alkalinity test head, and a processor. The bottom of the mounting housing includes a downward-pointing truncated cone. A square groove is recessed at the bottom of the truncated cone, and a guide groove connected to the upper part of the square groove is recessed on the outside of the truncated cone. The bottom of the acidity / alkalinity test head extends into the square groove. A water tank is arranged around the upper part of the truncated cone, and a curved groove connecting the water tank and the guide groove is recessed on the outside of the truncated cone. A water supply pipe extending downward into the water tank is located at the top of the mounting housing. Through this method, the self-cleaning device for acidity and alkalinity detection utilizes the water supply pipe to fill the water tank. Some of the water in the tank flows through the curved groove into the guide groove and finally into the square groove, cleaning the acidity / alkalinity test head. This method is convenient to operate and highly efficient.

[0004] However, this technology does not address the technical issues and solutions of this application. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a simple structure for controlling the acidity of a glass processing cleaning tank by adding alkali to the cleaning water tank to neutralize the acid in the cleaning water without diluting it with water, thereby meeting the needs of cleaning water, avoiding the adverse effects of substandard water on products, ensuring the quality of cleaning water, saving water resources, and reducing wastewater treatment costs.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] This utility model is a pH control device for a glass processing cleaning water tank. The cleaning water tank is connected to a pump body, the pump body is connected to an alkaline solution storage tank, a pH probe is installed in the cleaning water tank, and the cleaning water tank is also equipped with a stirring blade.

[0008] The cleaning water tank is connected to the pump body through the first pipeline.

[0009] The pump body is connected to the alkali storage tank via a second pipeline.

[0010] The pH probe is connected to the control unit, and the pump body is also connected to the control unit.

[0011] A first solenoid valve is installed on the first pipeline, and a second solenoid valve is installed on the second pipeline.

[0012] A motor is installed on the inner wall of the cleaning tank, and the motor is connected to the stirring blades. The motor is set to tilt towards the bottom of the cleaning tank.

[0013] The first and second solenoid valves are respectively connected to the control components.

[0014] The pump body is a pneumatic pump.

[0015] The cleaning tank has a square cavity structure, and a motor is installed on the inner wall of each side of the cleaning tank.

[0016] The working principle and beneficial effects of this utility model are as follows:

[0017] The pH control device for a glass processing cleaning tank described in this invention includes a pH probe inside the cleaning tank to measure the pH concentration of the cleaning water in real time. An alkali storage tank stores high-purity alkali solution with an alkali content of 40%-60%. The cleaning tank is connected to a pump, which in turn is connected to the alkali storage tank, allowing the required amount of alkali solution to be pumped into the cleaning tank. When the pump starts, it draws the alkali solution into the cleaning tank to neutralize the weak acid. In practical use, the pH probe acts as a detection component, displaying the real-time pH concentration in the cleaning tank and transmitting the signal to a control unit (PLC). When the acid concentration in the cleaning tank exceeds a set range, the control unit activates the pump, drawing the alkali solution from the storage tank into the cleaning tank. When the pH concentration in the cleaning tank reaches the set range, the control unit stops the pump supplying acid. This allows for continuous monitoring of the pH concentration within the cleaning tank and continuous replenishment of the alkaline solution. It reliably neutralizes the cleaning water in the tank, ensuring the pH concentration meets the requirements for glass cleaning. Furthermore, the operation is simple, eliminating the need for large amounts of water to neutralize the acid. Attached Figure Description

[0021] The following description, with reference to the accompanying drawings, provides a more detailed explanation of the specific embodiments of this utility model, including the shape and structure of each component, the relative positions and connections between the parts, the functions and working principles of each part:

[0022] As attached Figure 1As shown, this utility model is a pH control device for a glass processing cleaning water tank. The cleaning water tank 1 is connected to a pump body 2, and the pump body 2 is connected to an alkaline solution storage tank 3. A pH probe 4 is installed inside the cleaning water tank 1, and the cleaning water tank 1 is also equipped with a stirring blade 5. To address the shortcomings of the prior art, an improved technical solution is proposed. In the structural design, a pH probe 4 is added inside the cleaning water tank to measure the pH concentration of the cleaning water in real time. The alkaline solution storage tank 3 is used to store alkaline solution, which is a high-purity alkaline solution with an alkaline content of 40%-60%. Simultaneously, the cleaning water tank 1 is connected to the pump body 2, and the pump body 2 is connected to the alkaline solution storage tank 3. This allows the alkaline solution in the alkaline solution storage tank 3 to be pumped into the cleaning water tank 1 in the required amount. When the pump body 2 is started, it is used to pump the alkaline solution into the cleaning water tank 1 to neutralize the weak acid. In practical use, the pH probe 4 acts as the detection component, monitoring the pH concentration of the water in the cleaning tank 1 in real time and transmitting the pH concentration signal to the control unit (PLC). When the acid concentration in the cleaning tank 1 exceeds the set range, the control unit activates the pump 2, which pumps the alkali solution stored in the alkali solution storage tank 3 into the cleaning tank 1. When the pH concentration in the cleaning tank 1 reaches the set range, the control unit stops the acid supply to the pump 2. This achieves continuous monitoring of the pH concentration in the cleaning tank 1 and continuous replenishment of the alkali solution. Thus, during glass cleaning, the cleaning water in the cleaning tank 1 is reliably monitored and neutralized, ensuring that the pH concentration of the water in the cleaning tank meets the cleaning requirements. Furthermore, the operation is simple, eliminating the need to add large amounts of water for acid neutralization. The pH control device for glass processing cleaning tank described in this utility model has a simple structure. It can neutralize the acid in the cleaning water by adding alkali to the cleaning tank, minimizing the acidity of the water without dilution with water, thus meeting the requirements of cleaning water, avoiding the adverse effects of substandard water on products, ensuring the quality of cleaning water, saving water resources, and reducing wastewater treatment costs.

[0023] The cleaning water tank 1 is connected to the pump body 2 via a first pipe 6. The pump body 2 is connected to the alkali storage tank 3 via a second pipe 7. In this structure, the first pipe 6 connects the cleaning water tank 1 and the pump body 2, and the second pipe 7 connects the pump body 2 and the alkali storage tank 3.

[0024] The pH probe 4 is connected to the control unit, and the pump body 2 is also connected to the control unit. In this structure, the pH probe 4 monitors the pH concentration of the water in the cleaning tank in real time and feeds the value back to the control unit. The control unit then determines whether to start the pump body 2 based on the actual value.

[0025] A first solenoid valve 8 is installed on the first pipeline 6, and a second solenoid valve 9 is installed on the second pipeline 7. The first solenoid valve 8 and the second solenoid valve 9 are respectively connected to a control component. With this structure, the control component can control the opening and closing of the first solenoid valve 8 and the second solenoid valve 9 respectively. When pumping alkali solution is not required, the control component controls the first solenoid valve 8 and the second solenoid valve 9 to close simultaneously. When pumping alkali solution is required, the control component controls the first solenoid valve 8 and the second solenoid valve 9 to open simultaneously. The cleaning water tank 1 is positioned lower than the main body and the alkali solution storage tank 3, allowing the supplied alkali solution to flow into the cleaning water tank 1 from the upper part.

[0026] A motor 9 is installed on the inner wall of the cleaning tank 1, and the motor 9 is connected to the stirring blade 5. The motor 9 is set to tilt towards the bottom of the cleaning tank 1. In this structure, the motor 9 is connected to a control unit. When the alkali solution is supplied, the control unit simultaneously controls the motor to start. The rotation of the motor drives the stirring blade 5 to rotate, stirring the water in the cleaning tank, so that the alkali solution is fully mixed.

[0027] The pump body 2 is a pneumatic pump. In the above structure, the pneumatic pump is controlled to start and stop via a control component. The cleaning water tank 1 has a square cavity structure, and a motor 9 is installed on each side of the inner wall of the cleaning water tank 1. In the above structure, multiple motors can control multiple stirring blades 5, thereby stirring the water in the cleaning water tank from different parts and improving the mixing effect.

[0028] The control component (controller) is a programmable logic controller (PLC) used to control glass processing and cleaning equipment. The control component of this invention is a direct application of existing mature technology and not an improvement.

[0029] The pH control device for glass processing cleaning tanks described in this utility model addresses the problem of increased acid concentration in the tanks after acid etching in the current industry. By adding a pH value probe pump and an alkali storage tank 3, alkali can be added to the tank to neutralize the acid concentration. This not only meets production needs but also reduces water consumption and saves wastewater treatment costs. It also eliminates the need to dilute the acid in the water with pure water, greatly improving the utilization rate of cleaning water.

[0030] The pH control device for a glass processing cleaning tank described in this invention adds a pH probe 4 to the cleaning tank to measure the pH concentration of the cleaning water in real time. An alkali storage tank 3 stores high-purity alkali solution with an alkali content of 40%-60%. Simultaneously, the cleaning tank 1 is connected to a pump body 2, which in turn is connected to the alkali storage tank 3. This allows the alkali solution in the storage tank 3 to be pumped into the cleaning tank 1 in the required amount. When the pump body 2 is started, it pumps the alkali solution into the cleaning tank 1 to neutralize the weak acid. In actual use, the pH probe 4 acts as a detection component, monitoring the pH concentration of the water in the cleaning tank 1 in real time and transmitting the pH concentration signal to the control unit (PLC). When the acid concentration in the cleaning tank 1 exceeds the set range, the control unit controls the pump body 2 to start, pumping the alkali solution stored in the storage tank 3 into the cleaning tank 1. When the pH concentration in the cleaning tank 1 reaches the set range, the control unit controls the pump 2 to stop supplying acid. This allows for continuous monitoring of the pH concentration in the cleaning tank 1 and continuous replenishment of the alkali solution. Thus, during glass cleaning, the cleaning water in the cleaning tank 1 is reliably monitored and neutralized, ensuring that the pH concentration of the water in the cleaning tank meets the cleaning requirements. Furthermore, the operation is simple, eliminating the need to add large amounts of water for acid neutralization.
