Description

Technical Field

[0001] The utility model relates to the field of polishing equipment, in particular to a polishing equipment for processing large-caliber high-temperature resistant flanges. Background Art

[0002] At present, a Chinese utility model with the announcement number CN216542604U discloses a grinding and polishing device for flange processing, including a mounting base, a flange body and a flange connection mechanism, wherein a mounting frame is fixedly mounted on the top of the mounting base, a rotating disk is rotatably connected to the top of the mounting frame, and the flange connection mechanism includes a plug-in rod and a mounting support plate. The grinding and polishing device for flange processing, by setting a flange connection mechanism, when the user is clamping the flange body, the user can directly place the flange body on the top of the rotating disk and pass the plug-in rod through the through hole opened on the flange body. After placement, the electric push rod contracts to complete the rapid clamping of the flange body. When the user needs to flip the flange body, the user can adjust the extension of the electric push rod and take out the flange body to complete the flipping process, so that the device has the advantage of being convenient for the user to take and flip the flange, which is convenient for the user to use;

[0003] Although the existing polishing equipment can limit the flange through the fixed component to prevent the flange from shifting during the polishing process, there are still other problems in the use process, such as slow polishing efficiency. Not only can the top of the flange be polished at a time, the surface of the flange needs to be assisted by other tools for secondary polishing, which will also block the polishing surface of the flange, reducing the polishing quality of the flange. Moreover, it does not have dust collection and purification function. A large amount of dust will be generated in the flange during the polishing process. After the dust is formed, it will fly upward. If the dust is inhaled by people, it will cause damage to the respiratory tract and pollute the surrounding environment. In order to solve the above-mentioned problems, we propose a polishing equipment for large-diameter high-temperature resistant flange processing. Utility Model Content

[0015] The utility model is further configured as follows: the top and the bottom of the activated carbon filter are both clamped with a clamping seat, and the other sides of the two activated carbon filters are bolted to the first fixing frame and the second fixing frame respectively.

[0016] By adopting the above technical solution, the activated carbon filter can be limited by setting the holder to prevent the activated carbon filter from leaking and shifting after being placed.

[0017] The utility model is further configured as follows: a protective net is bolted to one side of the first fixing frame.

[0018] By adopting the above technical solution and setting the protective net, it is possible to prevent foreign objects from entering the axial flow fan through the exhaust slot.

After the first motor is started, it will drive the rotating disk and the flange to rotate, and the fourth motor will drive the threaded plate to move backward. When the threaded plate moves to the right, it will drive the flange to enter the first fixed frame. After the flange enters, the second motor and the third motor are started at the same time. After starting, the second motor and the third motor will drive the first polishing piece and the second polishing piece to polish the surface and top of the flange synchronously, which can achieve a good polishing effect, which not only speeds up the polishing efficiency of the flange, but also ensures the uniformity of the polishing of the flange surface;

[0021] 2. The utility model starts the axial flow fan, which will rotate the internal impeller after starting. The impeller will discharge the air inside the second fixed frame from the exhaust slot when rotating. When the second fixed frame is in a negative pressure state, the dust-containing gas during flange grinding will be sucked in through the suction port. The dust-containing gas will pass through the activated carbon filter when flowing. The activated carbon filter will adsorb and intercept impurities and particulate matter in the gas, and can have the dust collection and purification function to prevent flying dust from being inhaled into the body of surrounding people, and can also improve the surrounding processing environment, with high practicality.
