Description

Technical Field

[0001] The utility model relates to the technical field of TFT-LCD glass substrates, in particular to a magnetic grid device for removing powder impurities. Background Art

[0002] In glass manufacturing, raw glass delivered from batching may contain metallic impurities and must undergo multiple filtration processes before entering the kiln to prevent these impurities from entering the kiln and potentially causing poor glass quality. In the production of TFT-LCD glass substrates, magnetic grids are crucial for absorbing iron impurities from the raw glass to prevent the formation of iron stones. However, the accumulation of adsorbed matter over time weakens the magnetic grid's adsorption capacity, necessitating regular cleaning and replacement.

[0003] Currently, manual cleaning and replacement are often used in manufacturing, a slow and difficult process that cannot guarantee complete removal of adsorbed materials. Therefore, it is necessary to develop a magnetic grating device for removing impurities that can efficiently and safely clean the magnetic grating on glass substrate production equipment, thereby addressing the above-mentioned shortcomings of the existing technology. Utility Model Content

[0004] The purpose of the present invention is to provide a magnetic grating device for removing powder impurities to overcome the problems existing in the prior art. The present invention can realize online rapid replacement of the magnetic grating, perform efficient and safe cleaning operations, facilitate installation and on-site cleaning, and greatly improve work efficiency.

[0005] In order to achieve the above-mentioned purpose, the technical solutions adopted by the present invention are as follows:

[0006] The suction cup is fixed to the suction cup, and the suction cup is tightened to the suction cup, and the suction cup is tightened to the suction cup.

[0007] Furthermore, a retaining ring is provided at the location where the magnetic tube passes through the sealing cover;

[0008] Furthermore, the sealing cover is provided with a plurality of holes;

[0009] Furthermore, the magnetic block device includes a plurality of magnetic blocks, and fixing plates are respectively installed at both ends of the plurality of magnetic blocks;

[0010] Furthermore, magnetic blocks are installed at both ends of the fixing plate to limit the position;

[0011] Furthermore, a baffle is installed on the pull-out rod inside the middle box, and the baffle is installed in front of the magnetic block device;

[0012] Furthermore, a magnetic block is installed at the front end of the baffle to limit the position;

[0013] Furthermore, an interface flange is provided at the bottom of the connecting port; a feed flange is provided at the top of the feed port, and the connecting port and the feed port are fixedly connected via the interface flange and the feed flange;

[0014] Furthermore, a box flange is provided on the top of the intermediate box body, a blanking flange is provided on the bottom of the feed box body, and the feed box body and the intermediate box body are fixedly connected via the blanking flange and the box body flange;

[0015] Furthermore, a discharge flange is provided at the bottom of the intermediate box body, and the intermediate box body is fixedly connected to the feeding equipment via the discharge flange.

[0016] The above technical solution has the following advantages or beneficial effects:

[0017] The utility model provides a magnetic grating device for removing impurities in powder materials. The box device adopts a multi-component combination design. By arranging the close cooperation of the feed box, the intermediate box and the sealing connection device, the magnetic grating can be replaced online quickly, and efficient and safe cleaning operations can be performed. It is convenient for installation and on-site cleaning, which greatly improves work efficiency. At the same time, it also ensures the overall stability and sealing of the device. The application of the sealing cover and the magnetic clamp effectively prevents the leakage of powder materials during the cleaning process, protects the working environment, and reduces dust pollution. The magnetic tube in the magnetic rod device and the built-in magnetic block device can effectively absorb magnetic impurities in the powder materials, such as iron filings, iron powder, etc. This physical separation method is fast and efficient, significantly improving the purity of the powder; the magnetic rod is connected to the pull-out rod through a handle, and the user can easily operate the handle to control the movement of the magnetic block device in the powder to achieve comprehensive capture of impurities. At the same time, the design of the pull-out rod allows the magnetic block device to extend and retract in the magnetic tube, which is convenient for adjusting the cleaning depth or removing the adsorbed impurities, thereby improving the flexibility and convenience of use; since both the magnetic rod device and the sealing connection device are detachable, the cleaning and maintenance of the equipment become simple and quick. When the magnetic block device on the magnetic rod is full of impurities, it can be easily removed for cleaning without stopping the machine or disassembling the entire device, reducing maintenance costs and downtime.

[0018] Furthermore, the setting of the retaining ring ensures the sealing with the sealing connection cover and the separation of impurities during cleaning. When the pull-out rod is closed, the powder removes impurities in the magnetic area during the falling process. When the impurities need to be cleaned, the magnetic rod is taken out and the pull-out rod is pulled open through the insulating ball on the magnetic rod. The impurities adsorbed on the magnetic tube will automatically fall off as the magnetic tube moves and are collected by the retaining ring, thereby realizing online cleaning and replacement, which helps to maintain the smooth operation of the device and improves the stability of the cleaning efficiency.

[0019] Furthermore, the magnetic block is firmly mounted on the pull-out rod by a fixing plate, which ensures the stability of the magnetic block during the operation of the device and helps prevent the magnetic block from falling off or shifting due to vibration or impact, thereby ensuring the continuity and reliability of the device; the stable magnetic block device can more effectively adsorb magnetic impurities in the powder, and the magnetic block is firmly fixed to maintain consistent magnetic field strength and direction, making the adsorption process more efficient and thorough; at the same time, it also simplifies the installation and replacement process of the magnetic block device. When the magnetic block needs to be repaired or replaced, the operator can easily remove and reinstall the magnetic block without large-scale disassembly of the entire device.

[0020] Furthermore, the design of the magnetic block limiter limits the movement range of the magnetic block on the pull-out rod, preventing the magnetic block from colliding or being damaged under extreme conditions (such as strong vibration), which not only extends the service life of the magnetic block but also reduces replacement costs.

[0021] Furthermore, the installation of the baffle provides an additional support point for the magnetic block device, which helps prevent the magnetic block from shifting or falling off when it absorbs a large amount of impurities or is subjected to external forces, thereby enhancing the stability of the entire magnetic block device; the baffle can also help optimize the impurity removal process. When the magnetic rod device moves in the powder, the baffle can guide the flow of powder, making it easier for magnetic impurities to be absorbed by the magnetic block. At the same time, the baffle can also prevent the absorbed impurities from falling back into the powder during the movement of the magnetic rod device.

[0022] Furthermore, the flange design is added to the bottom of the connection port, the top of the feed port, the bottom of the feed box, and the top and bottom of the intermediate box. First, it can ensure the tight connection between the various parts of the device, and connect them to the corresponding pipes or equipment through bolts or other fasteners, thereby improving the stability of the connection between the entire magnetic grid device and the peripheral system; secondly, the flange connection design makes the installation and disassembly of the magnetic grid device more convenient and quick. When the device needs to be maintained, cleaned or parts are replaced, the device can be easily separated by loosening the fasteners on the flange, further improving efficiency; finally, the flange design can ensure that the device remains sealed during operation to prevent powder leakage or external impurities from entering.
