Description

Technical Field

[0001] This invention belongs to the technical field of substrate glass or cover glass channel equipment, specifically relating to a method for installing and adjusting a platinum channel stirring rod. Background Technology

[0002] During normal use of the substrate glass or cover glass channel equipment, the platinum channel stirring rod is installed on the channel stirring mechanism. The channel stirring mechanism drives the platinum stirring rod to rotate in the molten glass in the platinum channel stirring tank at the speed and direction required by the process, thereby homogenizing the molten glass in the stirring tank, further improving the quality of the molten glass and meeting the process requirements.

[0003] Platinum stirring rods are core equipment in the channel industry, playing a decisive role in channel processes. The installation and adjustment methods of the stirring rod directly determine its performance. Due to the small gap between the platinum stirring rod and the inner wall of the mixing tank, improper installation and adjustment will severely affect the stirring effect of the platinum stirring rod, thereby impacting the quality of the molten glass in the mixing tank and seriously affecting the normal production process of the channel. On the other hand, improper installation and adjustment can easily lead to scratches between the stirring rod blades and the inner wall of the mixing tank. Platinum scraped off and entering the molten glass in the mixing tank will also cause a decline in the quality of the molten glass, resulting in defects such as platinum particles or rhodium lines in the product. In addition, because the mixing tank wall is thin, scratches on the inner wall of the mixing tank can easily cause leakage of molten glass. The leaked molten glass will corrode the refractory material on the outside of the platinum channel, seriously affecting the service life of the platinum stirring rod, the mixing tank, and the refractory material of the channel. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention aims to provide a method for installing and adjusting a platinum channel stirring rod, so as to solve the technical problems such as the stirring rod blades scraping against the inner wall of the stirring tank and the leakage of molten glass, which are caused by improper installation and adjustment of the stirring rod, resulting in a decline in the quality of molten glass.

[0005] To achieve the above objectives, the present invention employs the following technical solution:

[0006] This invention discloses a method for installing and adjusting a platinum channel stirring rod, comprising the following steps:

[0007] S1: First, perform preparatory installation work for the installation and adjustment of the platinum channel stirring rod; then place the platinum stirring rod in the installation position, connect the top connecting flange of the stirring rod to the connecting flange of the stirring mechanism, and connect the top connecting flange of the stirring rod to the top of the platinum stirring rod.

[0008] S2: Rotate the connecting flange of the stirring mechanism at a constant speed, measure the runout of the bottom blade end face of the platinum stirring rod, and adjust until the runout is ≤0.8mm;

[0009] S3: Adjust the lifting device of the stirring mechanism to make the stirring mechanism drive the platinum stirring rod to descend slowly. Stop the descent of the platinum stirring rod when the bottom blade of the platinum stirring rod just enters the inner wall of the stirring tank, and adjust the front-back and left-right gap deviation between the outermost edge of the bottom blade of the platinum stirring rod and the inner wall of the stirring tank to ≤1mm.

[0010] S4: Adjust the lifting device of the stirring mechanism to make the stirring mechanism drive the platinum stirring rod to descend slowly. After checking and confirming that the position of the platinum stirring rod has descended to the working position required by the process, lock the locking device of the stirring mechanism. The installation and adjustment of the platinum channel stirring rod is now complete.

[0011] Furthermore, in S1, the preparatory installation work for installing and adjusting the platinum channel stirring rod includes the following steps:

[0012] S11: First, check and confirm that the construction and installation of the channel mixing tank meet the requirements, and that the top of the mixing tank is covered with protective material for protection; check and confirm that the installation of the channel mixing mechanism meets the requirements and that it operates normally, measure the end face runout of the mixing mechanism connecting flange ≤0.03mm, and check and confirm that the center of the mixing mechanism connecting flange coincides with the center of the mixing tank.

[0013] S21: Raise the connecting flange of the stirring mechanism to the position close to the top dead center of the stirring mechanism and lock it. Measure and confirm that the distance from the bottom of the connecting flange of the stirring mechanism to the top of the stirring tank is 80-120mm longer than the total length of the platinum stirring rod.

[0014] S31: Check and confirm that the relevant dimensions of the platinum stirring rod meet the requirements, and that the dimensions of the top connecting flange of the stirring rod, the connecting flange of the stirring mechanism, and the insulating flange are matched.

[0015] Furthermore, in S1, the top connecting flange of the stirring rod and the connecting flange of the mechanism are connected by several insulating connecting devices; the insulating connecting devices include connecting bolts, nuts, gaskets and insulating sleeves, and the top connecting flange of the stirring rod and the connecting flange of the mechanism are bolted together by bolts, nuts and gaskets placed between them; insulating sleeves are placed at the bottom and top of the connecting bolts.

[0016] Furthermore, the plurality of insulating connection devices are installed diagonally among each other.

[0017] Furthermore, in S1, an insulating flange is provided between the top connecting flange of the stirring rod and the connecting flange of the mechanism; during connection, the insulating flange is first placed between the top connecting flange of the stirring rod and the connecting flange of the stirring mechanism, and then connected by several insulating connecting devices.

[0018] Furthermore, in S2, before manually rotating the connecting flange of the stirring mechanism at a constant speed, ensure that the blades at the bottom of the platinum stirring rod and the top of the stirring tank do not touch, and install the magnetic base and dial indicator at the dial indicator measurement position at the lower end of the platinum stirring rod.

[0019] Furthermore, in S2, the method for adjusting until the runout is ≤0.8mm is as follows:

[0020] If the runout of the bottom blade end face of the platinum stirring rod is greater than 0.8 mm, loosen the insulating connection device to create a gap between the insulating flange and the top connecting flange of the stirring rod. Place the prepared stainless steel or copper sheet between the insulating flange and the top connecting flange of the stirring rod, then tighten the insulating connection device. Measure the runout of the bottom blade end face of the platinum stirring rod again. If the measurement data still does not meet the requirements, repeat the above operation, selecting stainless steel or copper sheets of other thicknesses, or adjusting the placement of the stainless steel or copper sheet until the runout is ≤0.8 mm.

[0021] Furthermore, in S3, before slowly lowering the platinum stirring rod, remove the protective material at the top of the stirring tank and loosen the locking device of the stirring mechanism; when the bottommost blade of the platinum stirring rod just enters the inner wall of the stirring tank, stop the descent of the platinum stirring rod, lock the locking device of the stirring mechanism, measure the minimum distance between the outermost edge of the bottommost blade of the platinum stirring rod and the inner wall of the stirring tank, measure four positions in the front, back, left, and right, and adjust the gap deviation between the outermost edge of the bottommost blade of the platinum stirring rod and the inner wall of the stirring tank to ≤1mm.

[0022] Furthermore, the method for adjusting the front-to-back and left-to-right clearance deviation between the outermost edge of the bottommost blade of the platinum stirring rod and the inner wall of the stirring tank to ≤1mm is as follows:

[0023] If the gap deviation between the left and right positions is greater than 1mm, adjust the left and right adjustment mechanism of the stirring mechanism until the gap deviation between the left and right positions is less than or equal to 1mm.

[0024] If the gap deviation between the front and rear positions is greater than 1mm, adjust the front and rear adjustment mechanism of the stirring mechanism until the gap deviation between the front and rear positions is less than or equal to 1mm.

[0025] Furthermore, in S4, before manually adjusting the lifting device of the stirring mechanism to slowly lower the platinum stirring rod, the locking device of the stirring mechanism is released.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] This invention discloses a method for installing and adjusting a platinum channel stirring rod. This method allows for the installation and adjustment of the platinum stirring rod on the substrate glass or cover glass. It not only enables quick and reliable installation of the stirring rod onto the stirring mechanism but also ensures that the gap between the installed and adjusted platinum stirring rod and the inner wall of the stirring tank meets requirements. This effectively avoids scratching between the stirring rod blades and the inner wall of the stirring tank, eliminating defects such as platinum particles and rhodium lines in the product, thus improving the product qualification rate. It also prevents damage to the platinum stirring rod and stirring bar caused by scratching, as well as leakage of molten glass from the stirring tank. This effectively extends the service life of the platinum stirring rod, the stirring tank, and the refractory material on the outside of the stirring tank, significantly reducing production costs.

[0039] This invention discloses a method for installing and adjusting a platinum channel stirring rod, comprising the following steps:

[0040] Step 1: Check and confirm that the construction and installation of the mixing tank meet the requirements, and cover the top of the mixing tank with protective materials for protection;

[0041] Step 2: Check and confirm that the channel mixing mechanism is installed in accordance with the requirements and operates normally. Measure the runout of the end face of the mixing mechanism connecting flange 3, which must be ≤0.03mm. Check and confirm that the center of the mixing mechanism connecting flange 3 and the center of the mixing tank 8 coincide.

[0042] Step 3: Raise the connecting flange 3 of the stirring mechanism to the position close to the top dead center of the stirring mechanism and lock it. Measure and confirm that the distance from the bottom of the connecting flange 3 of the stirring mechanism to the top of the stirring tank 8 is 80-120mm longer than the total length of the platinum stirring rod 6.

[0043] Step 4: Check and confirm that the relevant dimensions of the platinum stirring rod 6 meet the requirements, that the dimensions of the top connecting flange 1 of the stirring rod, the dimensions of the connecting flange 3 of the stirring mechanism, and the dimensions of the insulating flange 2 match, and check that the insulating flange 2, insulating sleeve 5, connecting bolts, nuts, gaskets, and installation measuring tools required for the installation of the platinum stirring rod 6 are complete and meet the requirements; among them, the insulating sleeve 5, connecting bolts, nuts, and gaskets constitute several insulating connection devices 4;

[0044] Step 5: Move the platinum stirring rod 6 to the installation position as a whole. Connect the top connecting flange 1 of the stirring rod and the connecting flange 1 of the stirring mechanism together with bolts, nuts, and washers. During connection, place the insulating flange 2 between the top connecting flange 1 of the stirring rod and the connecting flange 3 of the stirring mechanism in advance. Place insulating sleeves 5 at the bottom and top of the connecting bolts. After installation, ensure that the platinum stirring rod 6 and the stirring mechanism are mutually insulated. The insulating connection device 4 is provided with 6 sets. During installation, the 6 sets must be installed diagonally and tightened to ensure that the flange connection is secure and the force is evenly distributed. The above installation process of the platinum stirring rod 6 is as follows: Figure 1 As shown;

[0045] Step 6: After the platinum stirring rod 6 is installed, check and confirm that the blades at the bottom of the platinum stirring rod 6 and the top of the stirring tank 8 are not in contact. Turn the stirring mechanism connecting flange 3 by hand to check and confirm that the platinum stirring rod 6 can rotate freely.

[0046] Step 7: Install the magnetic base and dial indicator to the dial indicator measuring position 7 at the lower end of the platinum stirring rod 6 and adjust it into place. Rotate the stirring mechanism connecting flange 3 by hand at a uniform speed to measure the runout of the bottom blade end face of the platinum stirring rod 6. Adjust the runout of the bottom flange end face of the stirring rod 6 to ≤0.8mm.

[0047] If the runout of the bottommost blade end face of the platinum stirring rod 6 is greater than 0.8mm, loosen the insulating connection device 4 to create a gap between the insulating flange 2 and the top connecting flange 1 of the stirring rod. Place the prepared stainless steel sheet or copper sheet between the insulating flange 2 and the top connecting flange 1 of the stirring rod, and then tighten the insulating connection device 4. Measure the runout of the bottommost blade end face of the platinum stirring rod 6 again. If the measurement data still does not meet the requirements, repeat the above operation, selecting stainless steel sheets or copper sheets of other thicknesses, or adjusting the placement of the stainless steel sheets or copper sheets until the runout is ≤0.8mm. The stainless steel sheets or copper sheets are available in various thicknesses from 0.01 to 0.05mm; select the appropriate thickness based on the runout of the stirring rod blades.

[0048] Step 8: Remove the protective covering from the top of the mixing tank 8, loosen the locking device of the mixing mechanism, and manually adjust the lifting device of the mixing mechanism to slowly lower the platinum stirring rod 6. Carefully observe the relative position between the bottom blade of the platinum stirring rod 6 and the inner wall of the mixing tank 8. Stop the lifting of the platinum stirring rod 6 when the bottom blade of the platinum stirring rod 6 just enters the inner wall of the mixing tank 8. Lock the locking device of the mixing mechanism. Use a stainless steel ruler to measure the minimum distance between the outermost edge of the bottom blade of the platinum stirring rod 6 and the inner wall of the mixing tank. Measure four positions: front, back, left, and right. Ensure that the dimensional deviation of the four measured positions is ≤1mm. If the left and right deviation is >1mm, the left and right adjustment mechanism of the mixing mechanism must be adjusted. If the front and back deviation is greater than 1mm, the front and back adjustment mechanism of the mixing mechanism must be adjusted. Finally, ensure that the front, back, left, and right deviations of the gap between the outermost edge of the bottom blade of the platinum stirring rod 6 and the inner wall of the mixing tank 8 are ≤1mm.

[0049] Step 9: Loosen the locking device of the stirring mechanism, manually adjust the lifting device of the stirring mechanism to slowly lower the platinum stirring rod 6. After confirming that the position of the platinum stirring rod 6 has reached the working position required by the process, lock the locking device of the stirring mechanism. The installation and adjustment of the platinum channel stirring rod are now complete. The adjustment process of the platinum stirring rod 6 is as follows: Figure 2 As shown.
