Description

Technical Field

[0001] This utility model relates to the field of chromium-free passivating agent production technology, and in particular to chromium-free passivating agent processing equipment. Background Technology

[0002] The function of metal passivators is to form an inorganic protective film on the surface of die-cast aluminum. This protective film can significantly improve the corrosion resistance of the metal, protect the color of the metal, and enhance its appearance. Chromium-free passivators are more environmentally friendly than traditional metal passivators because they do not contain chromium.

[0003] Patent publication number CN215540197U discloses a stirring device for the production of chromium-free passivation solution, including a stirring drum. A top cover plate is fitted onto the top of the stirring drum, and a stirring sampling tube is installed at the bottom of the top cover plate. Stirring rods are equidistantly mounted around the surface of the stirring sampling tube, and suction nozzles are mounted on the surface of the stirring rods. A sampling hose is installed inside the stirring sampling tube, and a branch pipe is connected to the end of the sampling hose. The end of the branch pipe extends into the interior of the stirring rods and connects to the output end of the suction nozzles. Oxidant delivery pipes are installed on the inner wall of the stirring drum at equal intervals. This utility model, by incorporating a stirring sampling tube, can simultaneously achieve stirring and multi-gradient sampling within the stirring drum, thereby ensuring comprehensive and reliable sampling results. This helps operators obtain accurate test results, avoids over-stirring or under-stirring, and improves stirring efficiency.

[0004] However, the above-mentioned feeding device still has certain shortcomings when adding materials. Generally, when the chromium-free passivating agent processing device is producing chromium-free passivating agent, the addition of sulfuric acid as an oxidant is often done in a single quantitative manner, and the feeding speed cannot be controlled during the addition process. Then, when the materials are mixed and reacted, the materials cannot be mixed and reacted quickly, which affects the production quality of the chromium-free passivating solution and thus reduces the effect of use.

[0033] Two fixed recesses 17 are fixedly connected to the top of the processing barrel 2. A fixed rotating shaft 18 is rotatably connected between the two sides of the inner wall of the fixed recesses 17. A fixed tamping bracket 19 is fixedly sleeved on the outer wall of the fixed rotating shaft 18. A drive assembly is rotatably connected to the bottom of the processing barrel 2. The drive assembly includes a drive rod 20 rotatably connected to the bottom of the inner wall. A drive push plate 21 and a drive stirring bracket 22 are fixedly sleeved on the outer wall of the drive rod 20. One end of the drive rod 20 passes through the processing barrel 2 and the receiving shell 4 and extends into the interior of the receiving shell 4. A drive worm gear 25 is fixedly connected to one end of the drive rod 20. A drive tamping disc 23 is movably sleeved on the outer wall of the drive rod 20. There is a drive retaining ring 24. Inside the receiving shell 4, there are two connecting push rods 26. One end of the connecting push rod 26 passes through the receiving shell 4 and the processing barrel 2 and is fixedly connected to a connecting gasket. The other end of the connecting push rod 26 is fixedly connected to a connecting arc block 27. A connecting spring 28 is movably sleeved on the outer wall of the connecting push rod 26.

A connecting sealing sleeve 29 is provided at the connection between the processing barrel 2 and the connecting push rod 26. The connecting push rod 26 drives the connecting gasket to push the driving tamping disc 23 to move, so that the driving tamping disc 23 can achieve the purpose of tamping and mixing the materials and additives.

[0034] The receiving housing 4 has a movable component connected to its side wall. The movable component includes a movable motor 30 fixedly connected to the side wall of the receiving housing 4. A movable rod 31 is fixedly connected to the output end of the movable motor 30. The end of the movable rod 31 passes through the receiving housing 4 and is rotatably connected to the inner wall of the receiving housing 4. A movable worm gear 32 is fixedly sleeved on the outer wall of the movable rod 31. The movable worm gear 32 is meshed with the drive worm wheel 25. Two movable cams 33 are fixedly sleeved on the outer wall of the movable rod 31. The movable motor 30 drives the movable rod 31 to rotate.

[0035] Working principle: In use, the additive to be added is first discharged into the bottom of the measuring cylinder 8 through the feeding hopper 9. Since the measuring cylinder 8 is equipped with the installation pipe 7, the installation valve on the installation pipe 7 is activated at the same time to control the speed at which the additive or purifying agent passes through the installation pipe 7 and is discharged into the installation channel 6. Then, the regulating motor 13 is started, which drives the regulating gear 15 and the regulating baffle 16 on the regulating rod 14 to rotate. Then, the regulating gear 15 meshes with the two installation gears 11, which drives the installation shaft 10 and the installation baffle on the installation gear 11 to rotate. This makes the two installation baffles and the regulating baffle 16 cooperate in a stepped discharge method, thereby controlling the speed of adding materials.

[0036] Next, the movable motor 30 is started, which drives the movable worm gear 32 on the movable rod 31 to rotate. Then, the movable worm gear 32 also drives the drive worm wheel 25 to rotate, which in turn drives the drive rod 20, the drive push plate 21, and the drive mixing bracket 22 to rotate. The drive mixing bracket 22 then stirs the materials and additives. At the same time, the drive push plate 21 provides a pushing force to its corresponding fixed tamping bracket 19, causing the fixed tamping bracket 19 to tamp and mix the materials back and forth along the direction on the fixed rotating shaft 18.

[0037] Two movable cams 33 are installed on the movable rod 31. The movable cams 33 push the corresponding connecting arc block 27 with a pushing force. Then, the connecting arc block 27 also drives the connecting push rod 26 and the connecting spring 28 to move along the direction of the receiving shell 4 and the processing barrel 2. At the same time, a connecting sealing sleeve 29 is installed between the connecting push rod 26 and the processing barrel 2 to seal the material. Then, the connecting push rod 26 drives the connecting gasket to move. At the same time, the connecting gasket also pushes the driving tamping disc 23 with a pushing force and moves along the direction of the driving rod 20, so that the driving tamping disc 23 further tamps and mixes the material. Then, the driving retaining ring 24 on the connecting push rod 26 acts as a stop to prevent the driving tamping disc 23 from returning to its original position after being pushed, so that the material and additives react fully.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
