Technical Field
[0001] This utility model relates to the field of cast iron pot processing technology, specifically a dust negative pressure recovery device for a cast iron pot rotary polishing equipment. Background Technology
[0002] Polishing is a crucial step in the manufacturing process of cast iron pots. However, traditional rotary polishing equipment for cast iron pots generates a large amount of dust during operation. If this dust is not collected and treated in a timely manner, it will spread into the working environment, causing dust accumulation in the workshop. This not only affects the health of workers but also poses certain safety hazards, such as dust explosions. Furthermore, existing polishing equipment does not have a dust negative pressure recovery device during use.
[0003] In addition, some existing dust collection devices have many problems during use. For example, the coverage of the polishing operation area is not comprehensive enough, resulting in incomplete dust collection. The filter device is inconvenient to clean or replace, and equipment failure is easily caused by filter blockage, which increases maintenance costs and downtime and affects collection efficiency.
[0004] According to the patent application published on the Internet, a positioning mechanism and a polishing device for cast iron pots (authorization announcement number: CN219234945U) are described, the positioning mechanism and the polishing device for cast iron pots include "secondary transmission screw, positioning components" etc., to achieve the polishing work.
[0005] Regarding the above description, the applicant believes the following issues exist:
[0006] This positioning mechanism and cast iron pot polishing equipment utilizes a two-stage transmission screw and positioning components to perform polishing work. During use, the equipment polishes the pot body using abrasive rollers. However, it cannot collect and absorb the dust generated during the polishing process. If this dust is not collected and treated in time, it will spread into the working environment, causing dust accumulation in the workshop. This not only affects the health of the workers but also poses certain safety hazards, such as dust explosions. Therefore, this equipment needs to be improved. Utility Model Content

[0044] Example 2
[0045] Please see Figure 1-7 Furthermore, based on Embodiment 1, the polishing mechanism 3 includes a support frame 31, which is fixedly connected to the rear top of the processing table 1. A second hydraulic cylinder 33 is fixedly connected to the top of the support frame 31, and a moving table 32 is fixedly connected to the bottom of the second hydraulic cylinder 33. A second servo motor 34 is fixedly connected to the left side of the moving table 32, and a rotating rod 35 is fixedly connected to the right side of the second servo motor 34. The right side of the rotating rod 35 is rotatably connected to the inside of the moving table 32. A connecting arm 36 is fixedly connected to the outside of the rotating rod 35, and a polishing wheel 38 is slidably connected to the inside of the connecting arm 36. A fixing pin 37 is threadedly connected inside the polishing wheel 38.
[0046] The moving stage 32 is slidably connected inside the support frame 31, and the fixing pin 37 passes through the connecting arm 36, which facilitates the stability of the polishing wheel 38 and also facilitates installation and disassembly.
[0047] In actual operation, when this device is used to polish cast iron pots, first select a matching fixed platform 226 according to the size of the cast iron pot, and insert the load-bearing frame 225 into the top of the rotating platform 223. The load-bearing frame 225 is fixed by the limiting shaft 224 to ensure the stability of the fixed platform 226. At this time, the cast iron pot can be slidably connected to the inside of the fixed platform 226. The fixed platform 226 is semi-circular and has anti-slip pads on the inside, which can firmly fix cast iron pots of different specifications and prevent displacement during the polishing process.
[0048] After fixing, the first hydraulic cylinder 213 drives the protective frame 214 and the sealing gasket 216 to move, and the protective frame 214 drives the guide rod 212 to slide inside the support frame 211. The support frame 211, guide rod 212, first hydraulic cylinder 213, protective frame 214, air suction hood 215, sealing gasket 216, conveying pipe 217, filter frame 218, fixed shaft 2194 and hose 219 are set in two sets, so that the two sets of protective frames 214 are in contact with each other and slide against each other, which can cover the cast iron pot polishing operation area in all directions.
[0049] At this point, the second hydraulic cylinder 33 can drive the moving table 32 to move up and down, and the second servo motor 34 drives the rotating rod 35 and the connecting arm 36 to rotate. With the help of the polishing wheel 38, the position, angle and pressure of the polishing wheel 38 can be flexibly adjusted according to the shape, size and polishing requirements of the cast iron pot, so as to realize diversified and precise polishing operations, improve the versatility and processing adaptability of the equipment, and the polishing wheel 38 is fixed by the fixing pin 37, which not only ensures stability, but also facilitates replacement. During the polishing process, the first servo motor 221 drives the rotating table 223 at the top of the rotating shaft 222 to rotate, and the fixed table 226 drives the cast iron pot to rotate, so as to realize the comprehensive polishing work.
[0050] During the polishing process, the centrifugal fan 2192 is connected to the conveying pipe 217 via the hose 219 and the tee pipe 2191. Together with the suction hood 215, it creates a strong negative pressure in the polishing area inside the protective frame 214, quickly drawing in the dust generated during polishing. This effectively prevents dust from spreading into the working environment, reducing dust accumulation in the workshop and lowering safety hazards. The filter frame 218, slidably connected inside the conveying pipe 217, filters and collects the absorbed dust. The filtered airflow is discharged through the rear of the centrifugal fan 2192. The filter frame 218 is fixed by the fixed shaft 2194, allowing operators to quickly remove it for cleaning or replacement, reducing equipment malfunctions caused by filter blockage and lowering maintenance costs and downtime. Operators need to periodically clean the dust inside the filter frame 218 by removing the fixed shaft 2194. The transparent protective frame 214 allows operators to observe the cast iron pot polishing process in real time.
[0051] In this application, the two sets of first hydraulic cylinders 213, second hydraulic cylinders 33, first servo motors 221 and 34, and centrifugal fan 2192 need to be connected to the same PLC control system to ensure coordinated operation between the equipment. The PLC control system is existing technology, and those skilled in the art are well aware of the operation method of this system. Furthermore, the first servo motor 221 and the second servo motor 34 are both model 90ST-J03330-EX-380V-AD38 (with explosion-proof effect).
[0052] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
