Description

Technical Field

[0001] The present invention relates to the technical field of float glass production, and specifically relates to an apparatus and method for operating graphite bars in a tin bath of float glass.

[0002] Article. Background Art

[0003] For the production of ultra-clear float glass, it is necessary to continuously clean the surface of the transition rollers to reduce the adhesion of tin oxides and sulfides on the roller surface, make the lower surface of the glass substrate clean and transparent, and obtain high-quality glass substrates. The transition roller area of ultra-clear float glass is a relatively enclosed space, and the cleanliness of the transition roller surface is the key to obtaining high-quality glass substrates. However, during the production process, due to the long pusher (6.5 - 7 meters), the front end of the pusher is likely to rub against the surface of the transition roller, causing damage to the surface of the transition roller; moreover, when inserting the graphite bar, it is easy to bring the sealing and heat-insulating mastic onto the roller surface and remain on the roller surface, forming surface defects such as bruises and dot-shaped adhesives on the lower surface of the glass substrate.

[0004] Chinese Patent: Lever-type wiping roller device for float glass transition roller table (Application No.: 201020616692.X) discloses a lever-type wiping roller device for float glass transition roller table, which includes a wiping roller graphite bar, a graphite bar groove block for fixing the graphite bar, the graphite bar groove block is connected to the pusher of the graphite bar groove block, the pusher passes through the linear motion guiding groove, and the other end of the pusher is hinged to one end of the lever mechanism, and the other end of the lever mechanism is connected to the counterweight combination block. This utility model can quantify the force of the pusher and can effectively and conveniently adjust the fitting of the graphite bar and the roller surface; this structure can ensure that the graphite bar is always in close contact with the roller surface without excessive friction causing abnormal rotation of the roller path, and its structure is simple and the operation is convenient. However, this patent does not solve the technical problems that when adding and replacing the graphite bar, the pusher is likely to rub against the surface of the transition roller and the graphite bar is easy to bring the sealing and heat-insulating mastic onto the roller surface. Summary of the Invention

[0005] The purpose of the present invention is to overcome the deficiencies in the prior art that when replacing the graphite bar, the pusher is likely to rub against the surface of the transition roller, causing damage to the transition roller; and the graphite bar is easy to bring the sealing and heat-insulating mastic onto the roller surface, and provides an apparatus and method for operating graphite bars in a tin bath of float glass. By setting the convex block at the end of the pusher, a safety space between the pusher and the roller surface of the transition roller is left, reducing the risk of rubbing against the surface of the transition roller during the replacement of the graphite bar. By setting the shielding device along the lower edge of the left U-shaped groove, it can well prevent the sealing mud and heat-insulating cotton from being brought onto the roller surface and can also fix the position of the pusher, thereby improving the production efficiency.

[0006] In order to achieve the above invention purpose, the present invention provides the following technical solutions:

[0007] A device for a graphite bar in the operation of a float glass tin bath, comprising a transition roller, a U-shaped groove, a spring gasket, a graphite bar, a knife-shaped steel sheet and a push rod.

[0008] Both ends of the transition roller are provided with transmission mechanisms, and the transmission mechanisms drive the transition roller to rotate.

[0009] The U-shaped groove is located below the transition roller. The top of the U-shaped groove is open. Both ends of the U-shaped groove are provided with U-shaped groove sealing ports, and sealing mud is provided at the U-shaped groove sealing ports.

[0010] The spring gasket is placed at the bottom of the U-shaped groove.

[0011] The graphite bar is arranged on the spring gasket in the U-shaped groove, and a groove is provided on the side of the graphite bar.

[0012] The knife-shaped steel sheet is arranged above the sealing port. The knife-shaped steel sheet is detachably connected to the U-shaped groove.

[0013] One end of the push rod is provided with a head, and a convex block is provided on the head. The convex block can be inserted into the groove.

[0014] The device for replacing the graphite bar in the float glass tin bath is arranged on the frame. Among them, one side of the transition roller is connected to the transmission mechanism, and the transmission mechanism drives the transition roller to rotate. A U-shaped groove is arranged below the transition roller. The U-shaped groove is a hollow structure with an open top for placing the graphite bar and the spring gasket. Both ends of the U-shaped groove are provided with U-shaped groove sealing ports. The sealing ports are used to seal the space of the U-shaped groove to create a suitable working environment for the transition roller of the ultra-clear float glass. A groove is provided on the side of the graphite bar to facilitate the placement and removal of the graphite bar from the U-shaped groove. The knife-shaped steel sheet is detachably connected to the upper side of the U-shaped groove sealing port and is used to separate the transition roller and the U-shaped groove sealing port to prevent the push rod from contacting and damaging the transition roller when placing and removing the graphite bar. One end of the push rod is provided with a convex block, and the convex block can be inserted into the groove on the side of the graphite bar to place and remove the graphite bar.

[0015] Preferably, the sealing mud is sealing mud and heat-insulating cotton. The sealing mud and heat-insulating cotton further enhance the sealing performance and heat-insulating performance of the U-shaped groove sealing port.

[0016] Preferably, the height of the spring gasket is adjustable. The spring gasket can keep the graphite bar always in contact with the transition roller, further enhancing the cleaning effect of impurities on the transition roller.

[0017] Preferably, the graphite bar is composed of multiple sections spliced together, and adjacent graphite bars are connected by connecting pieces.

[0018] The multiple-section graphite bars are spliced together by connecting pieces, which can reduce the mass of each graphite bar and facilitate the installation and removal by the staff.

[0019] Preferably, the groove is provided in the lower half of the graphite bar.

[0020] The upper half of the graphite bar will be gradually worn out with the continuous use of the transition roller. Setting the groove in the lower half of the graphite bar facilitates the complete preservation of the groove, and thus facilitates the staff to install and remove the graphite bar.

[0021] Preferably, a handle is provided at one end of the push rod away from the end.

[0022] The end of the push rod is used to cooperate with the groove on the graphite bar for placing and removing the graphite bar, and the handle at the other end facilitates the staff to grip.

[0023] Preferably, a handle is provided on the knife-shaped steel sheet, and the handle is connected to the knife-shaped steel sheet through a connecting rod.

[0024] The knife-shaped steel sheet is in a sheet structure. By inserting the knife-shaped steel sheet, it can prevent the push rod from contacting the transition roller and prevent the sealing mud from falling onto the graphite bar.

[0025] A method for operating a graphite bar in a float glass tin bath includes the following steps:

[0026] S1. Clean the dust and oil stains near the sealing openings of the two-sided U-shaped grooves, open the sealing openings of the U-shaped grooves, remove the sealing mud at the sealing openings, insert the knife-shaped steel sheet above the U-shaped grooves to separate the transition roller and the sealing openings of the U-shaped grooves;

[0027] S2. Insert the push rod into one side of the sealing opening of the U-shaped groove, insert the convex block on the end of the push rod into the groove of the graphite bar, push the push rod towards the other side of the sealing opening of the U-shaped groove, unload the graphite bar in turn at the other side of the sealing opening of the U-shaped groove, and take out the spring gasket;

[0028] S3. Push the clean spring gasket through the sealing opening of the U-shaped groove to the bottom of the U-shaped groove;

[0029] S4. Place the replaced graphite bars into the U-shaped grooves in sequence and place them on the spring gaskets. The graphite bars are connected to each other through the cooperation of the connecting parts and the grooves, and adjust the positions of the graphite bars;

[0030] S5. Pull out the knife-shaped steel sheet, stuff the sealing and heat-insulating mud at the sealing opening of the U-shaped groove, and close the sealing opening of the U-shaped groove to complete the replacement of the graphite bar.

[0031] Preferably, in step S3, the height of the spring gasket is adjusted to 5-6 cm.

[0032] Adjust the height of the spring gasket in the initial state, that is, ensure that the graphite bar contacts the roller surface of the transition roller to obtain a good wiping effect and facilitate the carrying out of the cleaning task.

[0033] Preferably, in the step S4, the distance from the edge of the graphite strip to the sealing opening of the U-shaped groove is 1-3 cm.

[0034] Keeping a certain distance between the graphite strip and the sealing opening of the U-shaped groove facilitates the subsequent setting of sealing mud and heat insulation cotton, and does not affect the cleaning effect of the transition roller.

[0035] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0036] (1) By arranging a knife-shaped steel sheet at the sealing opening of the U-shaped groove, the present invention plays a shielding role to prevent the sealing mud and heat insulation cotton at the top from being brought onto the roller surface of the transition roller; the end bump of the push rod can fix the position of the push rod, leaving a safe space between the push rod and the roller surface of the transition roller, reducing the risk of rubbing against the surface of the transition roller during the operation of the graphite strip.

[0037] (2) By arranging a bump at the end of the push rod, and through the cooperation of the bump and the groove on the side of the graphite strip, the present invention can better take out and place the graphite strip. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] As Figures 1-6 shown, a device for operating graphite bars in a float glass tin bath is provided on a frame 1. One side of a transition roller 2 is connected to a transmission mechanism, and the transmission mechanism drives the transition roller 2 to rotate. A U-shaped groove 3 is arranged below the transition roller 2. The U-shaped groove 3 is a hollow structure with an open top for placing a graphite bar 5 and a spring gasket 4. The spring gasket 4 is designed with an adjustable height, and the spring gasket 4 can keep the graphite bar 5 in contact with the transition roller 2 all the time, enhancing the cleaning effect of impurities on the transition roller 2. A groove 51 is formed on the side surface of the lower half of the graphite bar 5, and the grooves 51 are spliced by connectors to form a graphite bar 5 that meets the length requirement. U-shaped groove sealing openings 31 are arranged at both ends of the U-shaped groove 3. The U-shaped groove sealing openings 31 are used to seal the space between the U-shaped groove 3 and the transition roller 2. Sealing and heat-insulating mud is also arranged at the U-shaped groove sealing openings 31. The sealing and heat-insulating mud is composed of sealing mud and heat-insulating cotton, and the sealing mud and heat-insulating cotton further enhance the sealing performance and heat-insulating ability of the U-shaped groove sealing openings 31, creating a suitable temperature field for the transition roller 2 of ultra-clear float glass.

[0052] The device for replacing the graphite bar 5 in the float glass tin bath is also equipped with auxiliary tools such as a knife-shaped steel sheet 7 and a push rod 6. The knife-shaped steel sheet 7 is a sheet structure, and a handle 71 is arranged at one end. The handle 71 is connected to the knife-shaped steel sheet 7 through a connecting rod 72. One end of the push rod 6 is provided with a head 61, and the other end is provided with a handle 63 for convenient grasping by the staff. A convex block 62 is arranged on the head 61. The convex block 62 can be inserted into the groove 51 on the side surface of the graphite bar 5, facilitating the smooth pushing out of the graphite bar 5 without damaging the transition roller 2. The width of the knife-shaped steel sheet 7 is the same as the width of the top of the U-shaped groove sealing opening 31. A clamping groove is arranged at the top end of the U-shaped groove sealing opening 31, and the knife-shaped steel sheet 7 can be inserted into the clamping groove to prevent the sealing mud and heat-insulating cotton at the top of the U-shaped groove sealing opening 31 from falling onto the graphite bar 5 and polluting the transition roller 2 during the process of penetrating the graphite bar 5. The position of the knife-shaped steel sheet 7 is between the transition roller 2 and the U-shaped groove 3. The convex block at the end of the push rod can prevent the push rod 6 from contacting the transition roller 2 and damaging the roller surface of the transition roller 2 when the graphite bar 5 is taken out.

[0053] Embodiment 2

[0054] A method for operating graphite bars in a float glass tin bath includes the following steps:

[0055] S1. Clean the dust and oil stains near the sealing opening 31 of the right U-shaped groove, open the sealing opening 31 of the U-shaped groove, remove the sealing mud and heat preservation cotton at the sealing opening 31 of the U-shaped groove, and insert the knife-shaped steel sheet 7 above the U-shaped groove 3;

[0056] S2. Insert the convex block 62 at the end 61 of the push rod 6 into the groove 51 of the graphite strip 5, push the push rod 6 towards the other end, sequentially remove the graphite strips 5 at the other end, and take out the spring washer 4;

[0057] S3. Push the clean spring washer 4 into the bottom of the U-shaped groove 3 through the sealing opening 31 of the U-shaped groove;

[0058] S4. Place the replaced graphite strips 5 on the spring washer 4 in the U-shaped groove 3 in sequence. The graphite strips 5 are connected by the connecting piece and the groove 51 in a matching manner, and adjust the position of the graphite strips 5;

[0059] S5. Pull out the knife-shaped steel sheet 7, stuff heat preservation cotton at the sealing opening 31 of the U-shaped groove and apply sealing mud, and close the sealing opening 31 of the U-shaped groove to complete the replacement of the graphite strip 5.

[0060] In step S1, first clean the oil stains and dust near the sealing opening 31 of the U-shaped groove to prevent oil stains and dust from entering the U-shaped groove 3 during the replacement of the graphite strip 5, which may affect the quality of the ultra-clear float glass. Subsequently, open the sealing opening 31 of the U-shaped groove, clean the sealing mud and heat preservation cotton at the top corners of the sealing opening 31 of the U-shaped groove from falling off. After cleaning, insert the knife-shaped steel sheet 7 into the card slot above the U-shaped groove 3 to prevent the remaining sealing mud and heat preservation cotton at the top of the sealing opening 31 of the U-shaped groove from falling off, separate the transition roller 2 and the sealing opening 31 of the U-shaped groove, and prevent the push rod 6 from contacting the transition roller 2.

[0061] In step S2, the staff holds the push rod 6 by hand, inserts the convex block 62 into the groove 51 on the side of the graphite strip 5, and pushes the graphite strip 5 towards the other end. Under the action of the thrust, the graphite strip 5 is pushed out from the sealing opening 31 of the U-shaped groove at the other end section by section. On the other side, the staff, under the protection of the high-temperature protection device, removes the graphite strips 5 section by section. After the graphite strip 5 is taken out, the spring washer 4 at the bottom of the U-shaped groove 3 is evenly pulled out.

[0062] In step S3, the new spring washer 4 is evenly pushed into the entire bottom of the U-shaped groove 3 through the sealing opening 31 of the U-shaped groove, and then the height of the spring washer 4 is adjusted to 6 cm.

[0063] In step S4, the clean graphite strips 5 are pushed into the spring washer 4 in the U-shaped groove 3 section by section in sequence. Each graphite strip 5 is connected by the connecting piece and the groove 51 in a matching manner. After all the graphite strips 5 are placed, adjust the position of the graphite strips 5, and the graphite strips 5 are 2 cm away from the sealing opening 31 of the U-shaped groove.

[0064] In step S5, take out the cutter steel sheet 7, reseal the U-shaped groove seal opening 31, put the sealing clay and the heat-insulating cotton at the U-shaped groove seal opening 31, and then close the U-shaped groove seal opening 31, thus completing the replacement work of the graphite strip 5.

[0065] Steps S1-S5 are the complete method for replacing the graphite strip 5 of the float glass tin bath, where S1-S2 are the methods for taking out the graphite strip 5, and S3-S5 are the methods for placing the graphite strip 5.
