Description

Technical Field

[0001] This application relates to the technical field of pickling tanks, and in particular to a cleaning mechanism for pickling tanks used in surface treatment. Background Technology

[0002] Pickling tanks are a type of equipment used in metal surface treatment processes. They are mainly used to remove oxide layers, rust, welding slag, and other impurities from metal surfaces through chemical methods. The pickling process usually involves the use of acidic solutions, such as hydrochloric acid, sulfuric acid, or phosphoric acid. These acidic solutions can effectively dissolve oxides and other contaminants on the metal surface, thereby achieving the purpose of cleaning and activating the metal surface.

[0003] As the pickling tank is used, impurities, metal ions and other contaminants will accumulate in it. This not only affects the pickling effect, but may also damage the workpieces being treated. Currently, manual cleaning is often used, which is laborious and inefficient, and there is still room for improvement. Utility Model Content

[0004] In order to reduce the labor costs of manual cleaning and improve cleaning efficiency when cleaning pickling tanks, this application provides a cleaning mechanism for pickling tanks used in surface treatment.

[0005] The cleaning mechanism for a surface treatment pickling tank provided in this application adopts the following technical solution:

[0006] A cleaning mechanism for a pickling tank for surface treatment includes a tank body with a cleaning structure. The cleaning structure includes a drive screw rotatably connected to the upper part of the tank body and driven by a motor, and a cleaning brush driven by the drive screw to slide horizontally. The cleaning brush is disposed inside the tank body and closely attached to the inner sidewall of the tank body. The cleaning brush includes a fixed end connected to the drive screw and a movable end movably connected below the fixed end. A first brush head is fixed on the movable end near the sidewall of the tank body. A movable plate is fixed on the movable end and embedded and positioned inside the fixed end.

[0007] By adopting the above technical solution, the driving screw drives the cleaning brush to slide horizontally along the inner wall of the tank. The first brush head removes impurities, metal ions and other pollutants attached to the inner wall of the tank. The fixed end is connected to the driving screw, and the movable plate realizes the detachable connection between the movable end and the fixed end. Thus, when needed, the movable end can be removed for manual assistance in further cleaning of local areas. This reduces the labor cost of manual cleaning and improves cleaning efficiency when cleaning the pickling tank.

[0008] Preferably, the cleaning brush is arranged opposite to each other in the pool body, including a first brush body and a second brush body. A deformable dovetail block is fixed on the movable end of the first brush body, and a dovetail groove for the dovetail block to be embedded is opened on the movable end of the second brush body. A locking hole is opened through the fixed ends of the first brush body and the second brush body, and a locking bolt can be correspondingly inserted into the locking hole.

[0009] By adopting the above technical solution, through the cooperation of the dovetail block and the dovetail groove and the fixing of the locking bolt, the first brush body and the second brush body can be tightly fixed to each other when needed, which facilitates increasing the cleaning area.

[0010] Preferably, a second brush head is fixed to the movable end adjacent to the first brush head and close to the side wall of the pool body, and a third brush head is fixed to the bottom of the movable end.

[0011] By adopting the above technical solution, the setting of the second and third brush heads increases the cleaning surface of the moving end, assisting the moving end to perform multi-directional cleaning; when cleaning the bottom of the pool, fixing the first and second brush bodies can combine the cleaning area of ​​the third brush head to increase the bottom cleaning area; while when manually assisting in cleaning the left and right side walls of the pool, fixing the first and second brush bodies and using the combination of the second brush head increases the side cleaning area.

[0012] Preferably, the fixed end is connected to the drive screw via a connecting structure.

[0013] Preferably, the connection structure includes a sliding block, a connecting plate, and an extension plate. The sliding block is horizontally slidably disposed on the drive screw and threadedly connected to the drive screw. The connecting plate extends from the sliding block, and the extension plate extends from the side wall of the fixed end. The connecting plate and the extension plate extend towards each other with a vertical offset. The connecting plate and the extension plate are fixed by connecting bolts.

[0014] By adopting the above technical solution, the horizontal movement of the first brush body and the second brush body is achieved by driving the sliding block to slide horizontally through the drive screw; then, by fixing the connecting plate and the extension plate, the fixed end can be detachably connected to the sliding block, which facilitates the removal of the cleaning brush and avoids obstructing the acid washing operation.

[0015] Preferably, a guide rod is fixed to one side of the drive screw, the guide rod passes through the sliding block, and the sliding block slides along the guide rod.

[0016] By adopting the above technical solution, the guide rod is set to maintain the horizontal sliding stability of the sliding block during the threaded engagement between the drive screw and the sliding block, thereby achieving the purpose of driving the movable end to move and clean the inner wall of the tank.

[0017] Preferably, the fixed end has a groove for the movable plate to be inserted, the movable plate is fixed in the groove by an insert bolt, and the end sidewall of the insert bolt is located in the groove.

[0018] By adopting the above technical solution, the embedding groove provides a space for the movable plate, and further fixes the movable plate by embedding bolts to maintain a stable connection between the movable end and the fixed end; at the same time, the end sidewall of the embedding bolt is located in the embedding groove to avoid obstruction when the first brush body and the second brush body are tightly fixed.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] The cleaning brush, driven by a screw, slides horizontally along the inner wall of the tank, removing impurities, metal ions, and other contaminants adhering to the inner wall through the first brush head. The fixed end is connected to the screw, and the movable plate allows for a detachable connection between the movable end and the fixed end, enabling the movable end to be removed when needed for further manual cleaning of specific areas. This reduces the labor required for manual cleaning and improves cleaning efficiency when cleaning acid pickling tanks.

[0021] The addition of the second and third brush heads increases the cleaning surface of the moving end, assisting the moving end in performing multi-directional cleaning.

[0022] By using the dovetail block and dovetail groove and fixing it with locking bolts, the first brush body and the second brush body can be tightly fixed together when needed to increase the cleaning area. When cleaning the bottom of the pool, fixing the first brush body and the second brush body can combine the cleaning area of ​​the third brush head to increase the bottom cleaning area. When manually cleaning the left and right side walls of the pool, fixing the first brush body and the second brush body can increase the side cleaning area by combining the second brush head.
