Description

Technical Field

[0001] This utility model relates to the field of chemical pickling tank technology, specifically to a self-adaptive chemical pickling tank with adjustable acid concentration. Background Technology

[0002] In industrial fields such as metal processing and electroplating pretreatment, pickling tanks are key equipment for removing oxide scale and rust from the surface of workpieces using acidic solutions.

[0003] Currently, in existing technologies, the concentration of acid in the pickling tank is generally detected by an acidity detector, and the concentration of acid is adjusted based on the detected concentration. However, in this process, since the acidity detector is generally installed in a fixed position, the acid concentration at the bottom of the pickling tank is higher than that at the top, resulting in a large deviation in the detection results and affecting the adjustment of the acid concentration. In view of this, an acid concentration adaptive automatic pickling tank is proposed. Utility Model Content

[0004] The main objective of this invention is to provide an acid concentration-adaptive automatic pickling tank that can solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model proposes an acid concentration-adaptive automatic pickling tank, comprising a tank body, a perforated plate fixedly connected to the inner wall of the tank body, an acidity detector embedded in the tank body, a sealing baffle detachably connected to the tank body, a disturbance component disposed below the perforated plate, and a reflux component and a vibration component disposed on the side wall of the tank body. The disturbance component includes:

[0006] The motor is fixedly mounted on a mounting bracket, and a bevel gear one is fixedly connected to the output shaft of the motor, and the bevel gear one meshes with a bevel gear two;

[0007] A rotating rod is fixed to a bevel gear. The rotating rod passes through the pool body and is rotatably connected to the pool body. The passage is sealed with a sealing element.

[0008] The agitator blade is fixedly connected to the upper side of the rotating rod. The rotation of the motor output shaft drives the first bevel gear to rotate, which in turn drives the second bevel gear to rotate, causing the rotating rod to drive the agitator blade to rotate, thereby agitating the acid solution in the tank and reducing the concentration difference of the acid solution in the pickling tank.

[0009] Preferably, the reflux assembly includes a fixed cylinder, which is fixedly connected to the outer wall of the pool body. The fixed cylinder is penetrated by a rotating shaft and rotatably connected to the rotating shaft. A spiral blade is fixedly connected to the outer wall of the rotating shaft. An outlet and an inlet are provided on the outer wall of the fixed cylinder.

[0010] Preferably, synchronous pulleys are fixedly connected to the outer walls of both the rotating shaft and the rotating rod, and these two sets of synchronous pulleys are connected by a synchronous belt drive. Through the use of the synchronous pulleys and the synchronous belt, the rotating shaft drives the spiral blades to rotate, so that the acid solution added at the inlet can be transported to the outlet for discharge, so that the acid solution at the bottom of the tank and the acid solution at the top of the tank can flow better, further reducing the acid solution concentration difference in the pickling tank.

[0011] Preferably, the liquid outlet is located above the pool body, the liquid inlet is connected to the pool body, and the liquid inlet is located below the through-hole plate.

[0012] Preferably, a disc is fixedly connected to the bottom of the rotating shaft, and a trapezoidal block is fixedly connected to the outer wall of the disc.

[0013] Preferably, the vibration assembly includes a connecting plate, which is fixedly connected to the outer wall of the pool body. The connecting plate is penetrated by a round rod and slidably connected to the round rod. A ring is fixedly connected to the outer wall of the round rod. The ring and the connecting plate are elastically connected by a return spring. A U-shaped piece is fixedly connected to the bottom of the ring, and a rotating wheel is rotatably connected to the U-shaped piece.

[0014] Preferably, an elastic telescopic rod is fixedly connected to the end of the round rod away from the U-shaped part, a striking rod is fixedly connected to the telescopic end of the elastic telescopic rod, and a striking block is fixedly connected to the bottom of the striking rod.

[0015] This invention provides an acid concentration-adaptive automatic pickling tank. It has the following beneficial effects:

[0016] (1) The acid concentration adaptive automatic acid washing tank uses the agitation component, the motor drives the stirring blade to rotate, and stirs the acid solution; the return component uses synchronous transmission to make the spiral blade rotate, and transports the acid solution at the bottom of the tank to the top, promotes the circulation and mixing of the upper and lower acid solutions, greatly reduces the concentration stratification phenomenon, avoids excessive or insufficient acid replenishment due to local concentration deviation, and ensures stable acid washing effect.

[0017] (2) The acid concentration adaptive braking pickling tank uses a vibration component. The rotating shaft drives the trapezoidal block to rotate, and the return spring makes the striking block strike the through plate periodically, shaking off the attached metal impurities and causing them to gather at the sealing baffle, which is convenient for centralized cleaning. There is no need to stop the machine frequently for manual cleaning, reducing production interruption. At the same time, it avoids the deposition of impurities from affecting the activity of the acid, ensuring that the workpiece and the acid are in full contact, and improving the uniformity and efficiency of the treatment.

[0026] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-5This utility model proposes an acid concentration adaptive automatic pickling tank, including a tank body 1, a through-hole plate 2 fixedly connected to the inner wall of the tank body 1, an acidity detector embedded in the tank body 1, a sealing baffle 3 detachably connected to the tank body 1, a disturbance component 4 arranged below the through-hole plate 2, and a reflux component 5 and a vibration component 6 arranged on the side wall of the tank body 1.

[0029] In an embodiment of this utility model, in order to reduce the acid concentration difference in the tank 1, the disturbance component 4 specifically includes a motor 41, a rotating rod 44, and an agitator 45. The motor 41 is fixedly mounted on the mounting frame, and a bevel gear 42 is fixedly connected to the output shaft of the motor 41. The bevel gear 42 meshes with a bevel gear 43. The rotating rod 44 is fixed to the bevel gear 43. The rotating rod 44 passes through the tank 1 and is rotatably connected to the tank 1. Its passage is sealed with a seal. The agitator 45 is fixedly connected to the upper side of the rotating rod 44. When the output shaft of the motor 41 rotates, it drives the bevel gear 42 to rotate, which in turn drives the bevel gear 43 to rotate, so that the rotating rod 44 drives the agitator 45 to rotate, thereby agitating the acid solution in the tank 1 and reducing the acid concentration difference in the pickling tank 1.

[0030] Furthermore, to further reduce the acid concentration difference in tank 1, the reflux assembly 5 specifically includes a fixed cylinder 51, which is fixedly connected to the outer wall of tank 1. The fixed cylinder 51 is penetrated by a rotating shaft 52 and rotatably connected to the rotating shaft 52. A spiral blade 53 is fixedly connected to the outer wall of the rotating shaft 52. An outlet 54 and an inlet 55 are provided on the outer wall of the fixed cylinder 51. Synchronous pulleys are fixedly connected to the outer walls of both the rotating shaft 52 and the rotating rod 44, and these two sets of synchronous pulleys are connected by a synchronous belt drive. The outlet 54 is located above tank 1. The inlet 55 is connected to the tank body 1 and is located below the through plate 2. By using the synchronous pulley and synchronous belt, when the rotating rod 44 rotates, it can drive the rotating shaft 52 to rotate, which in turn drives the spiral blade 53 to rotate, so that the acid solution added by the inlet 55 can be transported to the outlet 54 for discharge. This allows the acid solution at the bottom and top of the tank body 1 to flow better, further reducing the concentration difference of the acid solution in the pickling tank body 1, reducing the concentration stratification phenomenon, avoiding excessive or insufficient acid replenishment due to local concentration deviation, and ensuring stable pickling effect.

[0031] In this embodiment of the invention, a disc 56 is fixedly connected to the bottom of the rotating shaft 52, and a trapezoidal block 57 is fixedly connected to the outer wall of the disc 56. The vibration assembly 6 includes a connecting plate 61, which is fixedly connected to the outer wall of the pool body 1. The connecting plate 61 is penetrated by a round rod 62 and slidably connected to the round rod 62. A ring 63 is fixedly connected to the outer wall of the round rod 62. The ring 63 and the connecting plate 61 are elastically connected by a return spring. A U-shaped piece 64 is fixedly connected to the bottom of the ring 63, and a rotating wheel 65 is rotatably connected to the U-shaped piece 64. The round rod 62 is away from the U-shaped piece 64. One end of the mold 64 is fixedly connected to an elastic telescopic rod 66, and a striking rod 67 is fixedly connected to the telescopic end of the elastic telescopic rod 66. A striking block 68 is fixedly connected to the bottom of the striking rod 67. The rotating shaft 52 drives the disc 56 to rotate clockwise, which in turn drives the trapezoidal block 57 to move. Under the action of the return spring, the rotating wheel 65 drives the round rod 62 to move up and down reciprocally, which in turn causes the striking rod 67 to drive the striking block 68 to strike and vibrate the through hole plate 2, so that the impurities can move to the sealing baffle 3, which facilitates the subsequent centralized treatment of the impurities.

[0032] It should be noted that all the electrical components mentioned above are existing technology products. Those skilled in the art should select, install, and debug the circuits according to their needs to ensure that all electrical appliances function properly. All components are general standard parts or parts known to those skilled in the art, and their structures and principles can be obtained by those skilled in the art through technical manuals or conventional experimental methods. No specific restrictions are imposed here.

[0033] In operation, the output shaft of motor 41 rotates, driving bevel gear 42 to rotate, which in turn drives bevel gear 43 to rotate. This causes rotating rod 44 to drive stirring blade 45 to rotate, agitating the acid solution in tank 1. Simultaneously, through the use of synchronous pulleys and synchronous belts, the rotation of rotating rod 44 drives rotating shaft 52 to rotate, which in turn drives spiral blade 53 to rotate, transporting the acid solution added at inlet 55 to outlet 54 for discharge. This allows for better flow of acid solution at the bottom and top of tank 1, reducing the concentration difference of acid solution in pickling tank 1. Furthermore, the acidity detector enables workers to automatically replenish acid using existing mechanisms such as pumps.
