Description

Technical Field

[0001] This utility model relates to the field of chemical deposition tank technology, and more specifically, to a self-cleaning circulating chemical deposition tank. Background Technology

[0002] Chemical deposition tanks are typically used in processes such as electroplating or chemical vapor deposition. They often contain various chemical residues, such as metal salts, organic matter, or other deposits, which can easily generate corrosive or toxic substances. Currently, most factories still rely on technicians equipped with protective gear to clean chemical deposition tanks manually. This manual cleaning not only poses a risk of injury but is also inefficient due to the generally large size of the tanks.

[0003] To address these issues, a self-cleaning circulating chemical deposition tank is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a self-cleaning circulating chemical deposition tank to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, a self-cleaning circulating chemical deposition tank is provided, including a deposition tank with a drain outlet at the bottom. The deposition tank has an annular structure with a sealed bottom and an opening at the top. The edge of the top of the deposition tank extends outward to form a skirt. An annular groove is formed at the top of the skirt. A transmission belt is installed in the groove. A spray plate and a roller brush are installed on the inner side wall of the transmission belt.

[0006] The spray plate has several nozzles on the side near the inner wall of the sedimentation tank. The top of the roller brush cylinder is connected to a motor, which is connected to the inner wall of the transmission belt via an electric telescopic rod. Brushes are provided on the circumference and bottom of the roller brush cylinder, and an ultrasonic generator is also provided inside the roller brush cylinder.

[0007] The top of the skirt is also provided with a drive mechanism for driving the transmission belt.

[0008] Furthermore, the transmission belt has a ring structure, with the lower half of the transmission belt located in the groove and the upper half located at the top of the skirt.

[0009] Furthermore, the drive mechanism includes a servo motor, a drive gear, and meshing teeth, the meshing teeth being equidistantly arranged along the outer side of the transmission belt, specifically located at the top edge of the outer side of the transmission belt;

[0010] The servo motor is located on the outside of the transmission belt, and the drive gear is fixedly mounted on the top of the servo motor. The drive gear is connected to the transmission belt through meshing gear transmission.

[0011] Furthermore, the inside of the roller brush cylinder is hollow, and an electromagnet is also installed inside the roller brush cylinder. The two ends of the sedimentation tank are semi-circular structures, and the diameter of the roller brush cylinder does not exceed one-quarter of the diameter of the two semi-circles.

[0012] Furthermore, the interior of the spray plate is provided with a water guide pipe connected to the nozzle, and the water guide pipe is fixed to the motor housing by a strap and moves with the motor.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] Because the two ends of the sedimentation tank are designed with a semi-circular structure, the roller brush can rotate smoothly inside the sedimentation tank, thus ensuring that the roller brush can clean every area inside the sedimentation tank. Furthermore, the combination of the drive mechanism and the motor allows the roller brush to revolve and rotate inside the sedimentation tank, which makes the roller brush achieve a better cleaning effect and greatly improves the cleaning efficiency of the sedimentation tank.

[0015] Based on the shape characteristics of the sedimentation tank, the drive mechanism is set at the top of the tank wall. This greatly frees up the space directly above the tank, making it easier to put or take materials into the tank. Attached Figure Description

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

[0021] Those skilled in the art will understand that, unless specifically stated otherwise, the singular forms “a,” “an,” and “described” used herein may also include the plural forms. It should be further understood that the word “comprising” as used in this specification means the presence of the described features, integers, steps, operations, elements, and / or components, but does not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or groups thereof.

[0022] Please see Figure 1-2 As shown, a self-cleaning circulating chemical deposition tank is provided, including a deposition tank 1. The deposition tank 1 has an annular structure with a sealed bottom and an opening at the top. The edge of the top of the deposition tank 1 extends outward to form a skirt 2. An annular groove 3 is provided at the top of the skirt 2. A transmission belt 4 is installed in the groove 3. A spray cleaning plate 5 and a roller brush 6 are installed on the inner side wall of the transmission belt 4.

[0023] The spray plate 5 has several nozzles on one side near the inner wall of the sedimentation tank 1. The top of the roller brush cylinder 6 is connected to a motor 7. The motor 7 is connected to the inner wall of the transmission belt 4 through an electric telescopic rod 8. The circumference and bottom of the roller brush cylinder 6 are provided with brushes. The material of the brushes is a soft brush or a nylon brush. An ultrasonic generator is also provided inside the roller brush cylinder 6.

[0024] The top of the skirt 2 is also provided with a drive mechanism for driving the transmission belt 4. The transmission belt 4 rotates in the groove 3 under the action of the drive mechanism. The roller brush 6 revolves synchronously in the sedimentation tank 1 under the action of the transmission belt 4. At the same time, the roller brush 6 rotates on its own axis under the action of the motor 7. When the roller brush 6 is in contact with the inner wall of the sedimentation tank 1, the roller brush 6 uses its revolution and rotation to clean the inner wall of the sedimentation tank 1. During the cleaning process, high-pressure water jets are sprayed out through the nozzles on the spray plate 5 to impact the inner wall of the sedimentation tank 1.

[0025] In this embodiment, the water pipe can be connected to an alkaline water source, an acidic water source, or deionized water as needed. Acidic cleaning agents are suitable for alkaline deposits such as metal oxides and carbonates, while alkaline cleaning agents are suitable for grease, organic matter, or polymer residues.

[0026] The position of the roller brush 6 is adjusted by changing the length of the electric telescopic rod 8. In conjunction with the transmission belt 4, the bottom of the roller brush 6 can contact every corner of the bottom of the sedimentation tank 1. Since the corners of the sedimentation tank 1 are rounded, the roller brush 6 can clean any part of the sedimentation tank 1, avoiding cleaning dead corners. In this embodiment, the diameter of the roller brush 6 is one-quarter of the diameter of the semicircles at both ends of the sedimentation tank 1. That is to say, in conjunction with the electric telescopic rod 8, the roller brush 6 only needs to make two revolutions under the drive of the transmission belt 4 to complete the cleaning of all areas of the sedimentation tank 1.

[0027] like Figure 1 and Figure 2 As shown, the transmission belt 4 has a ring structure, with the lower half of the transmission belt 4 located in the groove 3 and the upper half located at the top of the skirt 2; the drive mechanism includes a servo motor 9, a drive gear 10 and meshing teeth 11, with the meshing teeth 11 equidistantly arranged along the outer side of the transmission belt 4, and the meshing teeth 11 specifically located at the top of the outer side of the transmission belt 4.

[0028] The servo motor 9 is located on the outside of the transmission belt 4. The drive gear 10 is fixedly installed on the top of the servo motor 9. The drive gear 10 is connected to the transmission belt 4 through the meshing teeth 11. Designing the entire drive mechanism above the side wall of the deposition tank 1 can maximize the space in the area directly above the deposition tank 1. The increased space directly above the deposition tank 1 is beneficial for taking out or putting in materials from the deposition tank 1.

[0029] In this embodiment, the inside of the roller brush cylinder 6 is hollow, and an electromagnet and an ultrasonic generator are also provided inside the roller brush cylinder 6. The electromagnet causes the roller brush cylinder 6 to generate magnetism, which can adsorb some of the metal deposits during rinsing; while the ultrasonic generator can remove the tiny deposits in the sedimentation tank 1.

[0030] In this embodiment, the interior of the spray plate 5 is provided with a water guide pipe connected to the nozzle. The water guide pipe is fixed to the housing of the motor 7 by a strap and moves together with the motor 7.

[0031] Work process:

[0032] Taking the cleaning of copper deposition tanks as an example, the deposits are copper oxide and copper carbonate;

[0033] Add a 10% dilute hydrochloric acid solution to the inside of sedimentation tank 1 for soaking;

[0034] First, adjust the roller brush cylinder 6 to fit against the inner wall of the sedimentation tank 1. Then, driven by the drive mechanism, the roller brush cylinder 6 revolves along the inner wall of the sedimentation tank 1. At the same time, driven by the motor 7, the roller brush cylinder 6 rotates on its own axis. After completing one revolution, adjust the length of the electric telescopic rod 8 so that the roller brush cylinder 6 moves by the length of its own diameter. Then, driven by the drive mechanism, it completes one revolution. In this way, the roller brush cylinder 6 completes the cleaning of the sedimentation tank 1.

[0035] Then, the water pipe is connected to clean water for rinsing. During this rinsing process, the drive mechanism is still used to enable the nozzle to rinse every corner of the sedimentation tank 1. Then, the water pipe is connected to a 5% sodium bicarbonate solution for neutralization. Finally, the water pipe is connected to deionized water to rinse the sedimentation tank 1.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
