Description

Technical Field

[0001] This utility model relates to the field of micro-etching pretreatment technology, specifically a micro-etching pretreatment water washing tank with temperature control function. Background Technology

[0002] Micro-etching pretreatment is a key step in surface treatment processes. It is mainly used to remove oxide layers, contaminants, etc. from the material surface, laying the foundation for subsequent micro-etching processes. Its purpose is to remove oil, dust, oxides, and other impurities from the metal surface, avoiding the influence of impurities on the reaction between the subsequent micro-etching solution and the substrate. Through light etching or physical action, a micro-rough structure is formed on the surface, increasing surface activity and adhesion, improving the bonding force of the plating or coating after micro-etching, adjusting the surface chemical state, and ensuring that the metal surface is in a suitable reactive state, thus ensuring that the micro-etching process is uniform and controllable.

[0003] The water washing process in the micro-etching pretreatment needs to control the water temperature to avoid the residual liquid on the surface crystallizing due to the water temperature being too low, or the surface being too high to accelerate secondary oxidation. Therefore, it is necessary to control the temperature inside the water washing tank of the micro-etching pretreatment, and the liquid in the tank may stratify due to the density difference. Utility Model Content

[0004] The purpose of this invention is to provide a micro-etching pretreatment water washing tank with temperature control function to solve the problem of temperature control and temperature stratification in the water washing tank mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a micro-etching pretreatment water washing tank with temperature control function, including an outer tank and an inner tank, wherein the inner tank is installed at the middle position of the bottom of the outer tank, and further includes a stirring structure for uniformly mixing liquids with different temperatures inside the inner tank.

[0006] The outer wall of the inner tank is fitted with a spiral cooling pipe, and the input end of the spiral cooling pipe is equipped with a water inlet pipe, the output end of the spiral cooling pipe is equipped with a water outlet pipe, and heating rods are installed at both the front and rear ends of the bottom of the inner tank. A temperature sensor is installed on the inner wall of the inner tank, and a support ring is installed on the inner wall of the inner tank above the temperature sensor. A loading plate is provided above the support ring. The stirring structure includes a drive motor, which is installed at the bottom of the outer tank. A drive gear is installed at the output end of the drive motor, and a stirring rod is rotatably installed at the middle position of the bottom of the inner tank. A stirring blade is installed at the top of the stirring rod, and a driven gear is installed at the bottom of the stirring rod.

[0007] Preferably, the front end of the water inlet pipe passes through the outer tank and extends to the front of the outer tank.

[0008] Preferably, the front end of the water outlet pipe passes through the outer tank and extends to the front of the outer tank below the water inlet pipe.

[0009] Preferably, the bottom end of the stirring rod passes through the inner tank and the outer tank in sequence, and the bottom end of the stirring rod extends to the bottom of the outer tank.

[0010] Preferably, the drive gear is located below the driven gear, and the drive gear and the driven gear mesh with each other.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: the drive motor drives the drive gear to rotate, which in turn drives the driven gear to rotate the stirring rod and stirring blades. This causes the stirring blades to stir and mix the liquid inside the inner tank. Subsequently, a temperature sensor detects the temperature of the liquid inside the inner tank. If the temperature is too low, the heating rod can be activated to heat the liquid inside the inner tank. If the temperature is too high, cooling water can be introduced into the spiral cooling pipe through the water inlet pipe. The cooling water cools the liquid inside the inner tank through the spiral cooling pipe surrounding the outer wall of the inner tank. This structure achieves the temperature control function of the washing tank through the action of the temperature sensor, the heating rod, and the spiral cooling pipe. The stirring structure can evenly mix the liquid in the tank, prevent the liquid temperature from separating, and improve the detection accuracy of the temperature sensor.

[0019] The outer wall of the inner tank 4 is fitted with a spiral cooling pipe 2, and the input end of the spiral cooling pipe 2 is equipped with a water inlet pipe 5 and the output end of the spiral cooling pipe 2 is equipped with a water outlet pipe 6. Heating rods 7 are installed at both the front and rear ends of the bottom of the inner tank 4. A temperature sensor 13 is installed on the inner wall of the inner tank 4, and a support ring 14 is installed on the inner wall of the inner tank 4 above the temperature sensor 13. A loading hole plate 3 is set above the support ring 14. The stirring structure includes a drive motor 8, and the drive motor 8 is installed at the bottom of the outer tank 1. A drive gear 9 is installed at the output end of the drive motor 8. A stirring rod 11 is rotatably installed at the middle position of the bottom of the inner tank 4. A stirring blade 12 is installed at the top of the stirring rod 11, and a driven gear 10 is installed at the bottom of the stirring rod 11.

[0020] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the front end of the water inlet pipe 5 passes through the outer tank 1 and extends to the front of the outer tank 1. The front end of the water outlet pipe 6 passes through the outer tank 1 and extends to the front of the outer tank 1 below the water inlet pipe 5. In use, cooling water is introduced into the spiral cooling pipe 2 through the water inlet pipe 5. The cooling water cools the liquid inside the inner tank 4 through the spiral cooling pipe 2 surrounding the outer wall of the inner tank 4, and then can be discharged through the water outlet pipe 6.

[0021] Specifically, such as Figure 2 , Figure 3 and Figure 4 As shown, the bottom end of the stirring rod 11 passes through the inner tank 4 and the outer tank 1 in sequence, and the bottom end of the stirring rod 11 extends to the bottom of the outer tank 1. When in use, the driven gear 10 drives the stirring rod 11 to rotate, and the driven gear 10 drives the stirring blade 12 to rotate, so that the stirring blade 12 stirs and mixes the liquid inside the inner tank 4.

[0022] Specifically, such as Figure 2 , Figure 3 and Figure 4 As shown, the drive gear 9 is located below the driven gear 10, and the drive gear 9 and the driven gear 10 mesh with each other. In use, since the drive gear 9 and the driven gear 10 mesh with each other, the drive gear 9 can drive the driven gear 10 to rotate.

[0023] Working principle: The operator introduces the liquid required for washing into the inner tank 4, starts the drive motor 8, and drives the drive gear 9 to rotate. Since the drive gear 9 meshes with the driven gear 10, the drive gear 9 can drive the driven gear 10 to rotate, which in turn drives the stirring rod 11 to rotate. The driven gear 10 drives the stirring blade 12 to rotate, causing the stirring blade 12 to stir and mix the liquid inside the inner tank 4. Then, the temperature sensor 13 detects the temperature of the liquid inside the inner tank 4. If the temperature is too low, the heating rod 7 can be activated to heat the liquid inside the inner tank 4. If the temperature is too high, cooling water can be introduced into the spiral cooling pipe 2 through the water inlet pipe 5. The cooling water cools the liquid inside the inner tank 4 through the spiral cooling pipe 2 surrounding the outer wall of the inner tank 4, and then it can be discharged through the water outlet pipe 6.
