Description

Technical Field

[0001] The invention relates to the technical field of glass channels, and in particular to a hot replacement method for a bearing box of a stirring mechanism, stirring equipment and a fixing device. Background Art

[0002] In the production process of substrate glass and cover glass, the platinum channel is the core equipment for the production of substrate glass and cover glass, and the platinum channel agitator is one of the core equipment of the platinum channel. Its main function is to drive the platinum agitator to rotate at a uniform speed in the platinum channel mixing barrel according to the speed and direction required by the production process through the stirring mechanism, thereby homogenizing the glass liquid in the mixing barrel, further improving the quality of the glass liquid and meeting the production and use requirements.

[0003] The platinum channel stirring mechanism works continuously in a harsh environment of high temperature and high humidity. The bearings, oil seals and other parts in the bearing box of the stirring mechanism are prone to failure after long-term use. If the bearings or oil seals in the bearing box of the stirring mechanism fail, it will have a fatal impact on the normal production process of the entire platinum channel, not only causing a significant drop in the yield rate of the entire production line or even no good products, but also seriously affecting the normal service life of the platinum channel. Therefore, if the bearings or oil seals in the bearing box of the stirring mechanism fail, they must be repaired as soon as possible. In the prior art, when replacing the bearing box, the stirrer needs to be raised, rotated, lowered and aligned to adjust the stirring mechanism. In this process, not only will the problem of contamination occur due to the long-term exposure of the stirring rod, but the second entry of the stirring rod into the glass liquid will directly affect the quality of the glass liquid. At the same time, due to the large temperature fluctuations of the stirring rod entering the glass liquid for the second time, it is not conducive to the accuracy and maintenance of the stirring rod. Summary of the invention

[0004] In view of the problem in the prior art that the stirring rod is exposed for a long time when replacing the bearing box of the stirring mechanism, resulting in deformation of the stirring rod that affects the accuracy and life, the present invention provides a hot replacement method for the bearing box of the stirring mechanism, a stirring device and a fixing device.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: The present invention provides a method for hot replacement of a bearing box of a stirring mechanism, comprising: Fix the agitator and keep its position in the mixing barrel unchanged; After the agitator is fixed, separate the agitator from the agitator mechanism bearing box and replace the spare bearing box; After the replacement of the spare bearing box is completed, the fixation of the agitator is released and the hot replacement of the bearing box of the agitator mechanism is completed.

[0006] Optionally, after the agitator is fixed, the stirring part of the agitator is located at the center of the stirring barrel.

[0007] The present invention provides a platinum channel stirring device, comprising a stirring mechanism bearing box, a stirrer, a motor, a bracket and a stirring barrel, wherein the stirring mechanism bearing box is a stirring mechanism bearing box replaced by the method described in claim 1 or 2; The motor, agitator and agitator mechanism bearing box are all arranged on a bracket, the power output end of the motor is connected to the power input end of the agitator mechanism bearing box through a transmission chain, and the power output end of the agitator mechanism bearing box is connected to the power input end of the agitator; the moving end of the agitator extends into the interior of the agitator barrel.

[0008] Optionally, a mixing barrel steel structure is provided around the mixing barrel, and when the agitator is fixed, the agitator is fixed on the mixing barrel steel structure.

[0009] Optionally, a first flange is provided on the top of the agitator, a second flange is provided on the power output end of the bearing box of the agitator mechanism, and the first flange is connected to the second flange by screws.

[0010] Optionally, an insulating flange is provided between the first flange and the second flange.

[0013] Optionally, the fixed connection portion includes a clamping opening arranged at the bottom of the support frame, and a tightening screw is arranged in the clamping opening.

[0014] Optionally, the support frame, the agitator fixing plate and the plurality of supporting square tubes are all connected by screws.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides a method for hot replacement of a stirring mechanism bearing box, wherein the method comprises fixing the stirrer to keep the position of the stirrer in the stirring barrel unchanged; after the stirrer is fixed, separating the stirrer from the stirring mechanism bearing box and replacing the spare bearing box; after the spare bearing box is replaced, releasing the fixation of the stirrer to complete the hot replacement of the stirring mechanism bearing box. The position of the stirrer remains unchanged during the whole process, thereby avoiding contamination caused by exposure of the stirrer during the replacement of the stirring mechanism bearing box, and avoiding deformation of the stirrer due to a large temperature change during the second immersion in the stirring barrel after being separated from the stirring barrel for a long time, which affects the precision and service life of the stirrer. In addition, compared with the traditional replacement method, the method of the present invention is simpler and faster, reduces the difficulty and complexity of operation, and improves work efficiency.

[0016] After the agitator is fixed, the agitator's stirring part is located in the center of the mixing barrel, which can ensure the position and stirring accuracy of the agitator after subsequent installation, so that it is located in the best stirring position to ensure that the material is subjected to uniform force from all directions during the stirring process, thereby achieving more efficient mixing.

[0032] The present invention is further described in detail below in conjunction with specific embodiments, which are intended to explain the present invention rather than to limit it.

[0033] See also Figure 1 The present invention discloses a method for hot replacement of a bearing box of a stirring mechanism, comprising: S1: fix the stirrer 2 to keep the position of the stirrer 2 in the stirring barrel 5 unchanged, specifically: use a special device for fixing the stirrer 2 to fix the stirrer 2 above the stirring barrel 5 to ensure that the stirring part of the stirrer 2 is always located in the center of the stirring barrel 5; S2: After the agitator is fixed, separate the agitator 2 from the agitator mechanism bearing box 1 and replace the spare bearing box. During the replacement of the spare bearing box, the agitator 2 is always located in the mixing barrel 5 and remains unchanged. Repeatedly check to confirm that the agitator 2 fixing device is securely installed and fixed. After the agitator 2 is in the correct position, remove the connecting bolts, nuts, gaskets, spring washers, insulating sleeves, etc. between the top connecting flange of the agitator 2 and the bottom connecting flange of the mixing mechanism bearing box 1. Note that you must work carefully during the entire operation to prevent the connecting parts from falling into or around the mixing barrel 2.

[0034] Check and record the stirring mechanism scale pointer, which is the normal working position of stirrer 2. Loosen the stirring mechanism locking device, manually and slowly raise the stirring mechanism about 10mm, carefully remove the insulation plate between the top connecting flange of the stirrer and the bottom connecting flange of the bearing box, and cover the top of the stirring mechanism with a high temperature resistant protective blanket. At this point, the stirrer and the stirring mechanism bearing box are completely separated.

[0035] Remove the transmission chain of the stirring mechanism, remove all the mounting screws of the stirring mechanism bearing box 1, remove the stirring mechanism bearing box 1 as a whole, and then install the prepared spare bearing box on the stirring mechanism. Use a frame level to measure the verticality of the newly replaced bearing box in the X and Y directions, and make adjustments if necessary. It must be ensured that the verticality of the bearing box in the X and Y directions meets the requirements. Then use a dial indicator to measure the end face runout of the flange at the bottom of the bearing box. If necessary, adjust the stirring mechanism. It must be ensured that the end face runout of the flange at the bottom of the bearing box is ≤0.05mm.

[0036] S3: After the replacement of the spare bearing box is completed, the fixation of the agitator 2 is released, and the hot replacement of the agitator mechanism bearing box 1 is completed. After the replacement of the bearing box is completed, the position limit of the agitator 2 is released, and the position of the agitator 2 is fine-tuned to ensure that it is in the best stirring position. After the replacement of the spare agitator mechanism bearing box is completed, the high temperature protection blanket covering the upper end of the top connecting flange of the agitator 2 is removed, and the insulating flange is placed on the upper end face of the top connecting flange of the agitator. Pay attention to check and confirm that the connection bolt hole positions match, and then manually slowly lower the agitator mechanism, pay attention to carefully observe the position of the bottom connecting flange of the agitator bearing box, and immediately stop the lowering operation of the agitator mechanism when the lower end face of the bottom connecting flange of the bearing box and the upper end face of the insulating flange just touch. Carefully check and measure whether the bottom connecting flange of the bearing box and the insulating flange are concentric in the front, back, left and right positions. If there is eccentricity, the front, back, left and right positions of the agitator mechanism must be adjusted according to the eccentricity direction and the eccentricity amount, and finally ensure that the bottom flange of the bearing box and the insulating flange are concentric and the connection bolt hole positions match. Finally, install the connecting bolts, nuts, gaskets, spring washers, insulating sleeves, etc. between the top connecting flange of the agitator and the bottom connecting flange and insulating flange of the agitator bearing box. After the connection between agitator 2 and the agitator bearing box is completed, check and confirm that the connection is secure, then manually and slowly raise the agitator about 10 mm to release the fixation of agitator 2.

[0037] Check and confirm the position of agitator 2, manually adjust the position of agitator 2 to the normal working position, lock the device, and then install the agitator mechanism transmission chain. The hot replacement of the entire agitator mechanism bearing box is completed. Turn on the platinum agitator according to the production process requirements and resume normal production.

The motor 3, the agitator 2 and the stirring mechanism bearing box 1 are all arranged on the horizontal bracket of the bracket 4. The power output end of the motor 3 is connected to the power input end of the stirring mechanism bearing box 1 through a transmission chain, and the power output end of the stirring mechanism bearing box 1 is connected to the power input end of the agitator 2; the moving end of the agitator 2 extends to the inside of the stirring barrel 5. A stirring barrel steel structure 6 is arranged circumferentially of the stirring barrel 5. When the agitator is fixed, the agitator 2 is fixed on the stirring barrel steel structure 6.

An insulating plate and an insulating sleeve are arranged between the supporting square tube 12 and the supporting frame 10 to ensure mutual insulation between the two. Considering the error of the supporting frame during processing and the deviation when the fixture is installed on site, we prepare several spare insulating plates in advance. The thickness of the insulating plates is 1mm, 2mm, 3mm, 5mm, etc. In order to increase the stability of the supporting square tube 12 and the supporting frame, connecting square tubes are arranged at both ends of the supporting frame 10.
