Description

Technical Field

[0001] This utility model relates to the field of chromium-free passivating agent processing technology, specifically to a chromium-free passivating agent mixing and quantitative feeding device. Background Technology

[0002] Chromium-free passivating agents are a type of metal passivating agent. The function of metal passivating agents is to form an inorganic protective film on the metal surface. This protective film can significantly improve the corrosion resistance of the metal, protect its color, and enhance its appearance. Chromium-free passivating agents are more environmentally friendly than traditional metal passivating agents because they do not contain chromium. During processing, they need to be mixed and quantitatively fed. A search revealed that patent CN221413002U3 discloses a chromium-free passivating agent mixing and quantitative feeding device, including a movable box with symmetrically fixed upper parts inside the box. A metering cup is fixedly connected to the bottom of the metering cup, and a conveying pipe is fixedly connected to the bottom of the conveying pipe. An electronic ball valve is fixedly connected to the bottom of the two electronic ball valves, and a mixing cup is fixedly connected to the bottom of the mixing cup. The mixing cup is also fixed to the moving box. A feeding device is fixedly connected to the bottom of the mixing cup. During use, the flow rate is controlled by the electronic ball valve, and the feeding is relatively slow. This can easily cause caking in the metering cup, which can lead to poor filling. Therefore, a chromium-free passivating agent mixing and metering feeding device is designed to facilitate unblocking during filling, avoid caking, and improve the smoothness of filling.

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. Example

[0022] Please see Figure 1-4A chromium-free passivating agent mixing and quantitative feeding device includes a mixing tank 1, a quantitative filling structure at the top of the mixing tank 1, a mixing structure inside the mixing tank 1, and a feeding valve 2 fixedly connected to the bottom of the mixing tank 1. The quantitative filling structure includes a fixed seat 3 that can be locked onto the top of the mixing tank 1. Two feeding channels 4 are symmetrically opened on the fixed seat 3. Each of the two feeding channels 4 is sealed and slidably fitted with a position-adjustable sealing adjustment slider 5. A quantitative hopper 6 is fixedly installed above the opposite side of the two feeding channels 4. The bottom of the quantitative hopper 6 is sealed and rotatably connected to a rotating cylinder 7 with a feeding port 8 at the bottom. A clearing mechanism is fixedly connected to the rotating cylinder 7. The device also includes a clearing drive mechanism that drives the rotating cylinder 7 and the clearing mechanism to rotate as a whole. A filling channel is formed between the sealing adjustment slider 5 and the feeding channel 4. When the rotating cylinder 7 rotates, the feeding port 8 intermittently communicates with the filling channel.

[0023] Specifically, the unblocking mechanism includes a central shaft 14 fixedly installed in the middle of the rotating drum 7, and a guide screw belt 15 fixedly installed on the central shaft 14. When the rotating drum 7 is driven to rotate, the central shaft 14 and the guide screw belt 15 can be driven to rotate as a whole, so that the material at the bottom of the quantitative hopper 6 can be unblocked through the rotating guide screw belt 15 to avoid the phenomenon of caking.

[0024] Specifically, the unblocking drive mechanism includes a feeding drive motor 10 fixedly mounted on a fixed base 3, a transmission shaft 9 rotatably connected between two feeding valves 2 through a sealed passage, and a transmission assembly 1 connecting the output shaft of the feeding drive motor 10 to the transmission shaft 9. Both ends of the transmission shaft 9 are respectively connected to the central shafts 14 on both sides through a transmission assembly 2. A sealing cover 13, fixedly connected to a metering hopper 6, is fitted around the outside of the transmission assembly 2. The feeding drive motor 10 is rotatably connected to the sealing cover 13. Further, the transmission assembly 1 includes two shafts respectively fixedly mounted on the output shaft of the feeding drive motor 10 and the transmission shaft 9. The transmission assembly includes two bevel gears 11 fixedly mounted on the ends of the transmission shaft 9 and the central shaft 14, and the two bevel gears 12 mesh with each other. When the feeding drive motor 10 is started, the output shaft of the feeding drive motor 10 rotates. Through the meshing of the two bevel gears 11, the transmission shaft 9 is driven to rotate. Through the meshing of the two bevel gears 12 at both ends, the central shaft 14 on both sides is driven to rotate. This, in turn, drives the rotating cylinder 7 and the guide screw belt 15 in the two metering hoppers 6 to rotate as a whole, ensuring the intermittent filling and material unblocking functions.

[0025] Specifically, the mixing structure includes a support frame 19 fixedly installed inside the mixing tank 1. A stirring shaft 20 is rotatably connected to the support frame 19, and a mixing and stirring ribbon 21 with a sliding fit against the inner wall of the mixing tank 1 is fixedly installed at the bottom. A lower locking block 22 is fixedly installed at the top of the stirring shaft 20. A mixing and stirring motor 25 is fixedly installed on the fixed base 3. A stirring drive shaft 24 is fixedly installed at the bottom output shaft of the mixing and stirring motor 25. An upper locking block 23 that can engage with the lower locking block 22 is fixedly installed at the bottom end of the stirring drive shaft 24. When the mixing and stirring motor 25 is started, it is convenient to drive the stirring drive shaft 24 to rotate. Through the cooperation of the upper locking block 23 and the lower locking block 22, the stirring shaft 20 and the mixing and stirring ribbon 21 are rotated as a whole.

[0026] Specifically, a diffuser blade 18 is provided below the packing channel and is rotatably connected to the fixed base 3. The diffuser blade 18 facilitates the dispersion of materials coming down from the packing channel, reducing the mixing difficulty of the mixing structure.

[0027] Specifically, an adjusting screw 16, which is threadedly connected to the fixed seat 3, is rotatably connected to the side of the sealing adjusting slider 5 away from the packing channel. An adjusting knob 17 is fixedly installed on the end of the adjusting screw 16 away from the sealing adjusting slider 5. By rotating the adjusting knob 17, the adjusting screw 16 can be easily rotated forward and backward, thereby driving the sealing adjusting slider 5 to move towards the packing channel, and thus adjusting the size of the packing channel.

[0028] Specifically, positioning ears are fixedly installed at the four corners of the fixed base 3, and multiple positioning screws 26 that slide and cooperate with the positioning ears are fixedly installed on the top of the mixing tank 1. It also includes positioning nuts 27 that can lock the positioning ears on the top of the mixing tank 1 and are threadedly engaged with the positioning screws 26. Through the cooperation of the positioning ears, positioning screws 26 and positioning nuts 27, the fixed base 3 can be easily locked on the top of the mixing tank 1.

[0029] In use, first move the device to a position above the feeding valve 2 where it is above the filling port. Then adjust the distance between the two sealing adjustment sliders 5 and the middle position to adjust the size of the filling channel. Next, offset the feeding port 8 from the filling channel. Then pour the two chromium-free passivating agent raw materials into the metering hopper 6 respectively. Then start the unblocking drive mechanism to drive the rotating drum 7 and the unblocking mechanism to rotate as a whole, so that the feeding port 8 can be intermittently connected to the filling channel, allowing the material to be intermittently filled into the mixing tank 1. At the same time as filling, the unblocking mechanism can unblock the material at the bottom of the metering hopper 6 to prevent caking. Through the mixing structure, the material entering the mixing tank 1 can be mixed as a whole. After mixing, the feeding valve 2 can be opened to perform the feeding operation.
