Description

Technical Field

[0001] The utility model relates to the technical field of stainless steel pickling and passivation equipment, in particular to a pickling and passivation device which is convenient for internal cleaning. Background Art

[0002] Stainless steel is the abbreviation of stainless acid-resistant steel. Steel that is resistant to weak corrosive media such as air, steam, water, or has stainless properties is called stainless steel. Due to its excellent corrosion resistance, high temperature stability, high hardness, and good aesthetics, it is widely used in processing parts of mechanical equipment such as construction and decoration, chemical and food processing, medical equipment, aerospace, etc.

[0003] In order to clean and protect the stainless steel surface, improve the corrosion resistance of stainless steel and increase its service life before the stainless steel raw materials leave the factory, the pickling passivation process will be adopted. The pickling stage mainly removes the oxides, pollutants and other impurities on the surface of the stainless steel by immersing the stainless steel in an acidic solution. This can purify the stainless steel surface, eliminate surface defects, and create a clean foundation for subsequent processing steps. Pickling can also improve the appearance of stainless steel, giving it a smoother and brighter surface.

[0004] In the process of realizing the present invention, the inventors found that the prior art had the following problems: 1. Compared with the static immersion method, the centrifugal flushing can completely decompose the medium solution on the surface of the raw material to achieve an ideal passivation effect, but many stainless steel raw materials are large in specifications, and this passivation method is only suitable for small parts; 2. The raw materials are usually passivated immediately after processing, and metal debris will inevitably be generated during the immersion and flushing process, which is easy to remain inside the immersion tank. Utility Model Content

[0005] The purpose of the utility model is to provide a pickling and passivation device that is easy to clean inside, so as to solve the problem that the centrifugal pickling and passivation equipment proposed in the above background technology is only suitable for small-sized raw materials, and most of the pickling and passivation equipment is easy to accumulate metal debris inside and is difficult to clean. In order to achieve the above purpose, the utility model provides the following technical solutions: a pickling and passivation device that is easy to clean inside, including a base, a vibration mechanism is welded on the top of the base, a storage box is provided at one end of the vibration mechanism, a passivation tank is fixedly connected to the top of the base, a metal basket and a roller brush are respectively provided above the passivation tank, the metal basket is fixedly connected to the transmission assembly through a quick-release assembly, and the transmission assembly is located above the metal basket and the roller brush;

[0006] The transmission assembly includes a stand, which is fixedly connected to the top of the base, one end of the stand is fixedly connected to a servo motor, the output end of the servo motor is fixedly connected to a lead screw, the lead screw is threadedly connected to a first nut and a second nut respectively, the first nut and the second nut are fixedly connected to a metal basket and a roller brush respectively through a hydraulic telescopic rod opened at the bottom thereof.

[0007] Further preferably, the stand is in a U-shape, with both ends of the stand away from both sides of the passivation tank, and the lead screw is rotatably connected to the inside of the stand, while the metal basket and the roller brush form a horizontal transmission structure above the passivation tank through the first nut and the second nut respectively.

[0008] Further preferably, the second nut is fixedly connected to the A interface through a hydraulic telescopic rod, and the A interface is plug-connected to the B interface, and the A interface and the B interface are respectively threadedly connected to the limit pins through the threaded holes opened therein, and the B interface is fixedly connected to the top of the roller brush through the mounting bracket.

[0009] Further preferably, the roller brush forms a lifting structure through a hydraulic telescopic rod, and the roller brush is rollingly connected in the mounting frame, and the roller brush is made of fiber material, and the roller brush is movably placed inside the storage box.

[0010] Further preferably, the quick-release assembly is provided with a U-shaped slot, and the U-shaped slot is fixedly connected to the bottom of the first nut through a mounting frame and a hydraulic telescopic rod, and the U-shaped slot is engaged with a card block, and the card block is fixedly connected to both ends of the metal basket through a tension spring and a mounting frame, and the metal basket is made of stainless steel with a hollow surface.

[0011] Further preferably, the vibration mechanisms are symmetrically distributed about the vertical center line of the passivation tank, and the interior of the vibration mechanism is fixedly connected to a cam through a motor provided therein, and the cams are respectively attached to the two ends of the outer wall of the passivation tank, and the passivation tank is made of aluminum alloy, and a discharge port is provided on one side of the passivation tank.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] In the utility model, the metal basket and the roller brush are driven by the first nut and the second nut to perform the operation process in different time periods in different categories. The metal basket is mounted on the transmission component through the quick-release component, which is not only convenient for the overall placement and removal of the raw materials, but also convenient for the separate cleaning of the inside of the metal basket after the filter holes of the metal basket are effectively intercepted and removed. The roller brush can be lowered into the passivation tank through the hydraulic telescopic rod. During the transmission process of the second nut, the bottom wall of the passivation tank can be cleaned in a rolling state due to its own movable structure with the mounting frame. The metal waste that cannot be discharged from the discharge port of the passivation tank and the solution on the surface of the passivation tank are adsorbed onto the surface of the roller brush, which solves the problem that the bottom position cannot be reached during manual cleaning and manual cleaning is required.

The structure of the roller brush that is easy to disassemble is also convenient for its own cleaning. At the same time, a storage box is provided, and another set of roller brushes that can be replaced are placed inside it.

[0014] In the utility model, the motor inside the vibration mechanism drives the cam to rotate while rotating. The cam will alternately knock on the outer wall of the passivation tank during the rotation. The external vibration mechanism will cause the internal solution to vibrate while knocking. Since all the raw materials are piled together, the passivation effect of the raw materials located in the middle of the accumulation point may be relatively poor compared to static immersion. The vibration will cause the solution to produce standing waves, which will have a certain impact on the raw materials immersed inside, so that the solution will evenly hit each position of the raw materials.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figures 1 to 6, the present utility model provides a technical solution: an acid pickling and passivation device convenient for internal cleaning, including a base 1, a vibration mechanism 2 is welded to the top of the base 1, a storage tank 3 is provided at one end of the vibration mechanism 2, a passivation tank 4 is fixedly connected to the top of the base 1, a metal basket 5 and a rotary brush 6 are respectively provided above the passivation tank 4, the metal basket 5 is fixedly connected to a transmission component 8 through a quick-release component 7, and the transmission component 8 is located above the metal basket 5 and the rotary brush 6;

[0024] The transmission component 8 includes a vertical frame 801, the vertical frame 801 is fixedly connected to the top of the base 1, a servo motor 802 is fixedly connected to one end of the vertical frame 801, a lead screw 803 is fixedly connected to the output end of the servo motor 802, the lead screw 803 is respectively threadedly connected with a first nut 804 and a second nut 805, and the first nut 804 and the second nut 805 are respectively fixedly connected to the metal basket 5 and the rotary brush 6 through hydraulic expansion rods 806 provided at their bottoms.

[0025] In this embodiment, as Figure 1 and Figure 3 shown, the vertical frame 801 is in a U shape, and both ends of the vertical frame 801 are far away from both sides of the passivation tank 4, and the lead screw 803 is rotatably connected inside the vertical frame 801. At the same time, the metal basket 5 and the rotary brush 6 respectively form a horizontal transmission structure above the passivation tank 4 through the first nut 804 and the second nut 805; the first nut 804 and the second nut 805 drive the metal basket 5 and the rotary brush 6 to perform operation processes separately in different time periods. The purpose of both ends of the vertical frame 801 being far away from both sides of the passivation tank 4 is to prevent the rotary brush 6 from being obstructed during the transmission of the second nut 805 due to the mounting frame below the first nut 804.

[0026] In this embodiment, as Figure 1 、 Figure 5 and Figure 6 shown, the second nut 805 is fixedly connected to an A interface 807 through a hydraulic expansion rod 806, and the A interface 807 is inserted and connected to a B interface 808. The A interface 807 and the B interface 808 are respectively threadedly connected with a limit pin through the threaded holes provided on them. At the same time, the B interface 808 is fixedly connected to the top of the rotary brush 6 through a mounting frame; after cleaning, it is necessary to clean the debris adsorbed on the surface of the rotary brush 6. The structure of the A interface 807 and the B interface 808 facilitates the disassembly of the rotary brush 6. At the same time, the limit pin can play a fixing role and is not likely to cause the problem of the rotary brush 6 falling off.

[0027] In this embodiment, as Figure 6As shown, the roller brush 6 forms a lifting structure through a hydraulic telescopic rod 806, and the roller brush 6 is connected to the mounting frame in a rolling manner. At the same time, the roller brush 6 is made of fiber material, and the roller brush 6 is movably placed inside the storage box 3; the fiber material has a certain adsorption force, and the total length of the roller brush 6 and the mounting frame fixing it is less than the internal width of the passivation tank 4, and the roller brush 6 can be lowered to the inside of the passivation tank 4 through the hydraulic telescopic rod 806. During the transmission process of the second nut 805, the roller brush 6 can be in a rolling state due to its own movable structure with the mounting frame to clean the bottom wall of the passivation tank 4, and the metal scraps that cannot be discharged from the discharge port of the passivation tank 4 and the solution on the surface wall of the passivation tank 4 are adsorbed to the surface of the roller brush 6, which solves the problem of being unable to reach the bottom position during manual cleaning and automatic cleaning. Since the roller brush 6 is made of fiber material and needs to be drained after cleaning, a storage box 3 is set, and another set of roller brushes 6 that can be replaced is placed inside it.

[0028] In this embodiment, Figure 4 As shown, the quick-release assembly 7 is provided with a U-shaped slot 701, and the U-shaped slot 701 is fixedly connected to the bottom of the first nut 804 through a mounting frame and a hydraulic telescopic rod 806, and the U-shaped slot 701 is engaged with a clamping block 702, and the clamping block 702 is respectively fixedly connected to the two ends of the metal basket 5 through a tension spring 703 and the mounting frame. The metal basket 5 is made of stainless steel with a hollow surface. The hollow structure of the metal basket 5 allows the solution to fully enter the raw material, and the metal basket 5 is movably framed on the transmission assembly 8 through the quick-release assembly 7, which is not only convenient for the overall placement and removal of the raw material, but also convenient for the separate cleaning of the inside of the metal basket 5 after the filter holes of the metal basket 5 are removed after effectively intercepting a part of the metal scraps.

[0029] In this embodiment, Figure 1 Figure 2 and Figure 6 As shown, the vibration mechanisms 2 are symmetrically distributed about the vertical center line of the passivation tank 4, and the interior of the vibration mechanism 2 is fixedly connected with a cam through the motor provided therein, and the cams are respectively attached to the two ends of the outer wall of the passivation tank 4, and the passivation tank 4 is made of aluminum alloy, and a drainage outlet is provided on one side of the passivation tank 4; the motor inside the vibration mechanism 2 drives the cam to rotate while rotating, and the cam will alternately knock on the outer wall of the passivation tank 4 during the rotation process, and the external vibration mechanism 2 will vibrate the internal solution while knocking, because the raw materials are all piled together, compared with static immersion, the passivation effect of the raw materials located in the middle of the accumulation point may be relatively poor, and the vibration will cause the solution to produce standing waves, which will have a certain impact on the raw materials immersed inside, so that the solution will be evenly hit at each position of the raw materials.

[0030] The use method and advantages of the utility model: The pickling passivation device which is convenient for internal cleaning, when in use, has the following working process:

[0031] like Figure 1, Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, first, the pickling solution is introduced from the top of the passivation tank 4 to two-thirds of the passivation tank 4, effectively ensuring that the internal solution of the vibration mechanism 2 will not splash out due to shaking during operation, and the raw materials to be passivated are placed inside the metal basket 5, and the metal basket 5 is fixed under the mounting frame connected to the first nut 804 by engaging the clamping block 702 to the inside of the U-shaped clamping groove 701, and the motor inside the power vibration mechanism 2 is started to drive the cam to rotate while rotating. During the rotation process, the cam will alternately knock on the outer wall of the passivation tank 4, and the external vibration mechanism 2 will vibrate the internal solution while knocking, and the vibration will cause the solution to generate standing waves. At the same time, under the action of the hydraulic telescopic rod 806, the metal basket 5 drives the raw material into the passivation tank 4, and the solution that generates the standing wave has a certain impact on the raw material immersed inside, so that the solution is evenly hit at each position of the raw material to complete the passivation. After the process, the hydraulic telescopic rod 806 drives the metal basket 5 to rise to the surface of the solution and wait for it to drain. Then, the metal basket 5 is removed by pulling the block 702 to enter the subsequent process. After the internal solution is extracted by connecting the external water pump through the discharge port outside the passivation tank 4, the vibration mechanism 2 is closed, and the servo motor 802 and the screw 803 rotate. During the rotation of the second nut 805, the roller brush 6 can be lowered to the inside of the passivation tank 4 through the hydraulic telescopic rod 806. During the transmission process of the second nut 805, due to its own active structure with the mounting frame, it can be in a rolling state to clean the inner wall of the passivation tank 4, and the impurities hanging on the surface of the passivation tank 4 are adsorbed on the brush, and the first nut 804 is driven together, which will not cause obstruction in the transmission process of the second nut 805. The roller brush 6 adsorbed with impurities can be separated by the lower limit pin A interface 807 and B interface 808, and the roller brush 6 is cleaned. At the same time, the roller brush 6 placed in the storage box 3 can be installed and used alternately.
