Once an accident occurs during the acid mixing process, it can easily cause personal injury and environmental pollution. Therefore, those skilled in the art provide an automatic acid mixing protection device for ceramic filter presses to solve the problems mentioned in the background art. Utility Model Content

[0024] Please see Figures 1-5In this embodiment of the present invention, an automatic acid mixing and protection device for a ceramic filter includes a base plate 1. An acid mixing tank 2, a water storage tank 5, and an acid storage tank 6 are respectively connected to the upper surface of the base plate 1. A sealed bearing 3 is embedded in the inner top wall of the acid mixing tank 2, and a stirring mechanism 4 is connected to the inner ring of the sealed bearing 3. Both the upper surfaces of the water storage tank 5 and the acid storage tank 6 are connected to injection ports 7. Metering pumps 8 are installed on the inner bottom walls of both the water storage tank 5 and the acid storage tank 6. The output ends of both metering pumps 8 are connected to delivery pipes 9. The output ends of the two delivery pipes 9 pass through the inner side walls of the water storage tank 5 and the acid storage tank 6, respectively, and extend into the interior of the acid mixing tank 2. Drain valves 1 are respectively connected to the outer surface of the acid mixing tank 2. The acid mixing tank 2 is equipped with a pressure relief valve 11, a concentration sensor 12 is installed on the inner bottom wall, a pressure sensor 13 is installed on the inner top wall, a PLC control box 14 is installed on the upper surface of the base plate 1, and an emergency stop button 15 is installed on the upper surface of the PLC control box 14. The stirring mechanism 4 includes a connecting rod 401 and a drive motor 403. Multiple stirring plates 402 are connected to the outer surface of the connecting rod 401. The top end of the connecting rod 401 is connected to the output end of the drive motor 403. The drive motor 403 can drive the connecting rod 401 and the stirring plates 402 to rotate. In this way, the rotation of the stirring plates 402 can be used to stir the acid solution mixed in the acid mixing tank 2, thereby making the acid solution more uniform.

[0025] The acid mixing tank 2 is made of stainless steel. Both the inner wall and the outer surface of the acid mixing tank 2 are coated with a corrosion-resistant coating. An indicator light 16 is installed on the left side of the PLC control box 14, and a touch screen 17 is installed on the front of the PLC control box 14. A model nameplate 18 is connected to the outer surface of the acid storage tank 6. A buzzer 19 is installed on the upper surface of the acid mixing tank 2. The corrosion-resistant coating on the inner wall and outer surface of the acid mixing tank 2 can give the acid mixing tank 2 a good corrosion resistance effect, thereby increasing the overall service life of the acid mixing tank 2. The touch screen 17 allows operators to easily and intuitively set the acid mixing parameters, and the buzzer 19 can promptly sound an alarm when the device malfunctions.

[0026] An L-shaped connecting frame 20 is connected to the upper surface of the acid mixing tank 2. The bottom surface of the L-shaped connecting frame 20 is connected to the upper surface of the drive motor 403. An observation window 21 is provided on the front of the acid mixing tank 2. The interior of the observation window 21 is connected with transparent glass. Mounting plates 22 are connected to the left and right sides of the base plate 1. Each mounting plate 22 has a set of mounting holes 23. The L-shaped connecting frame 20 can support the drive motor 403, which can make the drive motor 403 run more stably. The observation window 21 allows the staff to easily check the acid ratio inside the acid mixing tank 2. The mounting plates 22 and mounting holes 23 allow the staff to easily fix the device together with the ground.

[0027] The working principle of this utility model is as follows: When using this device, the operator first injects sufficient water and acid into the water storage tank 5 and acid storage tank 6 respectively through the injection port 7. Then, the required acid concentration and other acid mixing parameters are set on the touch screen 17 of the PLC control box 14. At this time, the PLC control box 14 controls the metering pump 8 at the bottom of the water storage tank 5 and acid storage tank 6 to start according to the set parameters, and delivers water and acid to the acid mixing tank 2 through the delivery pipe 9 according to the corresponding ratio. At this time, the 403 drive motor drives the connecting rod 401 and the stirring plate 402 to rotate, thereby stirring the water and acid entering the acid mixing tank 2 to make them fully mixed and uniform. During the process, the concentration sensor 12 inside the acid mixing tank 2 will detect the acid concentration in real time, and the pressure sensor 13 will also monitor the pressure inside the acid mixing tank 2 in real time and feed the data back to the PLC control box 14. If the concentration sensor 12 detects that the acid concentration has not reached the set value, the PLC control box 14 will adjust the working state of the metering pump 8, increasing or decreasing the delivery of water and acid until the concentration meets the requirements. At the same time, if the pressure sensor 13 detects that the pressure inside the acid mixing tank 2 exceeds the safe range, the PLC control box 14 will control the pressure relief valve 11 to open, release the pressure, and immediately stop the operation of the device. The above is the complete operation process of this device.
