Technical Field

[0001] This utility model relates to the field of industrial equipment technology, and in particular to an acid pickling tank. Background Technology

[0002] In the metal processing and chemical industries, pickling is an important process step used to remove oxides, rust, and impurities from metal surfaces. An acid mixing tank is a specialized piece of equipment used to prepare acid solutions. It can mix different types of acids with water or other solvents according to specific requirements and proportions to obtain acid solutions with specific concentrations and properties, meeting the needs of various processes in industrial production, such as pickling, etching, and chemical synthesis.

[0003] Currently, there is a type of pickling acid mixing tank. The tank body is the core part of the acid mixing tank. After various acid mixing materials enter the tank in sequence, in order to ensure that the acid and solvent are fully mixed, a stirring component is generally used to stir the liquid for mixing, or a water pump is used to extract the liquid from the bottom and discharge it to the top for mixing. However, both of these methods will cause damage to the stirring rod and the inside of the water pump due to the corrosiveness of the acid. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides an acid pickling tank, which aims to solve the problem that the acid solution will corrode the electrical equipment used for mixing when the acid solution is mixed.

[0015] 2. In this utility model, the temperature inside the tank is monitored in real time by a thermometer and a data analyzer. When the temperature reaches an abnormal value, the processor sends a signal to the controller to close the valve, stop feeding, and start the second air pump to forcefully extract the gas generated in the tank due to excessive reaction.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Reference Figures 1-3 This utility model provides an embodiment of an acid pickling tank, comprising a base plate 1, a support 2 fixedly connected to the top of the base plate 1, a tank body 3 fixedly connected to the top of the support 2, a cover plate 4 fixedly connected to the top of the tank body 3, an overflow prevention pipe 5 fixedly connected to the right side of the tank body 3, a first exhaust pipe 7 fixedly connected to the top of the cover plate 4, a first air pump 13 fixedly connected to the top of the cover plate 4, an air supply pipe 14 fixedly installed at the output end of the first air pump 13, an air extraction pipe 15 fixedly installed at the input end of the first air pump 13, a component box 6 fixedly connected to the top of the cover plate 4, a uniformly distributed first feed pipe 8 fixedly connected to the front side of the component box 6, a second feed pipe 12 fixedly connected to the rear side of the first feed pipe 8, a valve 9 rotatably connected between the first feed pipe 8 and the second feed pipe 12, and an explosion-proof component provided on the top of the cover plate 4. The explosion-proof component is used to prevent the tank from exploding in case the acid reacts excessively during use.

[0024] Specifically, acid and solution are sequentially fed into tank 3 through multiple first feed pipes 8. A first air pump 13 is installed on the top of the cover plate 4. When the first air pump 13 is activated, it draws air from the top of tank 3 through the air extraction pipe 15 and discharges it to the bottom of tank 3 through the air delivery pipe 14. This allows the acid to be repeatedly mixed by the surging of gas. The gas generated during acid mixing is discharged to the recovery system through the first exhaust pipe 7. After purification, it is discharged outdoors, which solves the problem that acid will corrode the electrical equipment used for mixing during acid mixing.

[0025] Reference Figure 4The explosion-proof component includes a second air pump 17, the bottom of which is fixedly connected to the top of the cover plate 4. An air inlet pipe 18 is fixedly installed at the output end of the second air pump 17, and a second exhaust pipe 21 is fixedly installed at the input end of the second air pump 17. A data analyzer 16 is fixedly connected to the right side of the inner wall of the component box 6. A thermometer 19 is fixedly connected to the bottom of the data analyzer 16, and an alarm 20 is fixedly connected to the top of the data analyzer 16.

[0026] Specifically, the temperature inside the tank 3 is monitored in real time by thermometer 19 and data analyzer 16. When the temperature reaches an abnormal value, processor 11 sends a signal to controller 10 to close valve 9, stop feeding, and start second air pump 17 to forcefully extract the gas generated in the tank 3 due to excessive reaction, thus solving the problem of the acid in the tank 3 exploding due to excessive reaction and pressure rise in the acid mixing tank.

[0027] Reference Figure 2 A controller 10 is fixedly connected to the top of valve 9, and a processor 11 is fixedly connected to the top of controller 10.

[0028] Specifically, the processor 11 sends a signal to the controller 10, which then controls the opening and closing of the valve 9 to control the discharge of the solution.

[0029] Reference Figure 3 The bottom of the gas supply pipe 14 extends through and to the bottom of the inner wall of the tank 3, and the bottom of the suction pipe 15 extends through and to the bottom of the cover plate 4.

[0030] Specifically, when the first air pump 13 is running, the air extraction pipe 15 draws air from the top of the tank 3, and then the gas is discharged to the bottom of the tank 3 by the gas delivery pipe 14 to push the acid liquid to mix.

[0031] Reference Figure 4 The processor 11 is fixedly connected to the data analyzer 16 on the right side. The temperature value is analyzed by the data analyzer 16 and then transmitted to the processor 11.

[0032] Specifically, when the temperature inside tank 3 reaches an abnormal value, the data analyzer 16 transmits the data to the processor 11, and the processor 11 causes the controller 10 to close valve 9 to stop feeding.

[0033] Reference Figure 4 The front side of the second air pump 17 is fixedly connected to the component box 6, and the opening and closing of the second air pump 17 is controlled by fixing the component box 6 to the second air pump 17.

[0034] Specifically, when the temperature inside the tank 3 reaches an abnormal value, the processor 11 controls the second air pump 17 to start, which powerfully pumps air out of the tank 3 to prevent it from exploding.

[0035] Reference Figure 4 The bottom of the air inlet pipe 18 extends through and to the bottom of the cover plate 4. The air inlet pipe 18 is used to extract the gas inside the tank 3.

[0036] Specifically, when the second air pump 17 is started, the gas in the tank 3 is extracted through the air inlet pipe 18, and then the gas is discharged to the recovery system through the second exhaust pipe 21.

[0037] Reference Figure 4 The thermometer 19 extends through the bottom of the cover plate 4 and is used to monitor the temperature inside the tank 3.

[0038] Specifically, the bottom of thermometer 19 is located at the top of tank 3 to monitor the temperature inside tank 3 in real time.

[0039] Working principle: During the preparation of the acid mixing tank, the processor 11 sends a signal to the controller 10, which then controls the opening and closing of the valve 9 to control the discharge of the solution. The acid and solution are sequentially put into the tank 3 through multiple first feed pipes 8 and second feed pipes 12. At the same time, the first air pump 13 is started. The first air pump 13 draws air from the top of the tank 3 through the air extraction pipe 15 and then discharges it to the bottom of the tank 3 through the air delivery pipe 14, so that the acid is repeatedly mixed by the surging of gas. The gas generated during the mixing of acid is discharged to the recovery system through the first exhaust pipe 7. After purification, it is discharged to the outside. Finally, the mixed acid is discharged from the discharge port at the bottom of the tank 3 for use.

[0040] During the acid mixing process, the temperature inside the tank 3 is monitored in real time by thermometer 19 and data analyzer 16. When the temperature reaches an abnormal value, processor 11 sends a signal to controller 10 to close valve 9, stop feeding, and start second air pump 17 to forcefully extract the gas generated in the tank 3 due to excessive reaction, preventing explosion due to increased pressure in the acid mixing tank.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
