[0002] In the glass production process, the furnace is a key piece of equipment used for glass heat treatment. When problems such as cracking, burning, or fire leakage occur in the furnace, the existing repair method is to shut down the furnace, wait for it to cool, and then apply mud for repair. This repair method is not only time-consuming, but also requires a large amount of energy to restore the furnace to the required temperature when restarting it, resulting in energy waste. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a mud gun for kiln repair, which can repair the kiln during hot operation.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a mud gun for kiln repair, comprising a piston, a tube body, and a discharge pipe fitting that is detachably disposed at one end of the tube body;

[0005] The piston includes a push rod and a push head disposed at one end of the push rod. The push head includes two horn-shaped sealing gaskets disposed opposite each other and a support block disposed in the horn-shaped sealing gaskets. The sidewall of the horn-shaped sealing gaskets abuts against the inner wall of the tube body. The push rod is used to drive the push head closer to or away from the discharge tube.

[0006] Furthermore, the pusher also includes a sealing gasket, which is disposed between two flared sealing gaskets, and the sidewall of the sealing gasket abuts against the inner wall of the tube.

[0007] Furthermore, the push rod is provided with a screw that passes through the flared sealing gasket and the support block, and a first nut is threaded onto the screw, the first nut abutting against the support block.

[0008] Furthermore, the discharge pipe includes a connecting pipe and a discharge pipe, wherein the connecting pipe is threadedly connected to the pipe body, and the discharge pipe is detachably connected to the connecting pipe.

[0009] Furthermore, the discharge pipe fitting also includes a threaded connector and a second nut. The threaded connector has a through hole that connects to the inner cavity of the pipe body. One section of the threaded connector is threadedly connected to the connecting pipe. The inlet end of the discharge pipe is inserted into the through hole. The second nut is sleeved on the discharge pipe and is threadedly connected to the other section of the threaded connector. A limiting ring is provided on the pipe wall of the discharge pipe between the second nut and the threaded connector.

[0010] Furthermore, the aforementioned mud gun for kiln repair also includes an operating handle threadedly connected to the end of the tube body away from the discharge pipe, wherein the push rod extends through the operating handle into the inner cavity of the tube body, and the operating handle is used to drive the push rod into the inner cavity of the tube body.

[0011] Furthermore, the operating handle includes a trigger hinged to the operating handle, a mounting block for threaded connection to the pipe body, and a first return spring;

[0012] The top of the trigger abuts against a first push plate, the first push plate having a first through hole for the push rod to pass through, the push rod passing through the first through hole and the mounting block in sequence and extending into the inner cavity of the tube body, and the first return spring being disposed between the first push plate and the mounting block;

[0013] When the trigger swings away from the tube body, the trigger pushes the first push plate, causing the first push plate to tilt toward the push head.

[0028] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0029] Please refer to Figures 1 to 3 As shown, this utility model discloses a mud gun for kiln repair, comprising a piston 1, a tube 2, and a discharge pipe 3 detachably disposed at one end of the tube 2; the piston 1 includes a push rod 11 and a push head 12 disposed at one end of the push rod 11, the push head 12 includes two flared sealing gaskets 121 disposed opposite to each other, and a support block 122 disposed in the flared opening of the flared sealing gaskets 121, the side wall of the flared sealing gaskets 121 abutting against the inner wall of the tube 2, and the push rod 11 being used to drive the push head 12 to approach or move away from the discharge pipe 3.

[0030] Working principle: Slurry is conveyed by a pusher head 12 driven by a pusher rod 11 installed inside the tube body 2. During operation, slurry is first poured into the inner cavity of the tube body 2. The flared sealing gasket 121 equipped with the pusher head 12 prevents slurry leakage, and the support block 122 added inside the flared sealing gasket 121 maintains its shape, ensuring a tight seal when the pusher head 12 moves. After the slurry is filled, the discharge pipe 3 is installed. Pushing the pusher rod 11 forces the slurry through the pusher head 12 into the discharge pipe 3, allowing repair personnel to directly use a slurry gun to repair the kiln.

[0031] It is worth noting that, please refer to Figure 3As shown, the support block 122 includes a bowl-shaped steel gasket 7 and a disc-shaped steel gasket 8. The disc-shaped steel gasket 8 is disposed at the bottom of the inner cavity of the horn-shaped sealing gasket 121, and the bowl-shaped steel gasket 7 is disposed at the horn opening of the horn-shaped sealing gasket 121 with the bowl opening facing the disc-shaped steel gasket 8.

[0032] In some implementations, please refer to Figure 3 As shown, the pusher head 12 also includes a sealing gasket 123, which is disposed between two flared sealing gaskets 121, and the sidewall of the sealing gasket 123 abuts against the inner wall of the tube body 2. The sealing gasket 123 further ensures the sealing performance of the pusher head 12 within the inner cavity of the tube body 2.

[0033] In some implementations, please refer to Figure 3 As shown, the push rod 11 is provided with a screw 111 that passes through the flared sealing gasket 121 and the support block 122. A first nut 4 is threaded onto the screw 111, and the first nut 4 abuts against the support block 122. The push head 12 is installed on the push rod 11 through the cooperation of the screw 111 and the first nut 4.

[0034] In some implementations, please refer to Figure 1 and Figure 4 As shown, the discharge pipe fitting 3 includes a connecting pipe 31 and a discharge pipe 32. The connecting pipe 31 is threadedly connected to the pipe body 2, and the discharge pipe 32 is detachably connected to the connecting pipe 31. Dividing the discharge pipe fitting 3 into a detachably connected connecting pipe 31 and a discharge pipe 32 allows for the replacement of different shaped discharge pipes 32 according to the actual repair situation, thus adapting to different repair environments. For example, a straight discharge pipe 32 can be used for repairs on the surface of the kiln, while a bent discharge pipe 32 can be used for repairs at the corner of the kiln.

[0035] In some implementations, please refer to Figure 4 As shown, the discharge pipe fitting 3 also includes a threaded connector 33 and a second nut 34. The threaded connector 33 has a through hole communicating with the inner cavity of the pipe body 2. One section of the threaded connector 33 is threadedly connected to the connecting pipe 31. The inlet end of the discharge pipe 32 is inserted into the through hole. The second nut 34 is sleeved on the discharge pipe 32 and is threadedly connected to the other section of the threaded connector 33. A limiting ring 321 is provided on the pipe wall of the discharge pipe 32, located between the second nut 34 and the threaded connector 33. By threading the second nut 34 to the threaded connector 33, the second nut 34 is pressed against the limiting ring 321, so that the discharge pipe 32 can be fixed to the connecting pipe 31.

[0036] In some implementations, please refer to Figure 1 and Figure 5As shown, the aforementioned mud gun for kiln repair also includes an operating handle 5 threadedly connected to the end of the tube 2 away from the discharge pipe 3. The push rod 11 extends into the inner cavity of the tube 2 through the operating handle 5, and the operating handle 5 is used to drive the push rod 11 into the inner cavity of the tube 2. During the repair process, the push rod 11 is controlled to extend into the inner cavity of the tube 2 by the operating handle 5, so that the mud material flows out from the discharge pipe 3.

[0037] In some implementations, please refer to Figure 5 As shown, the operating handle 5 includes a trigger 51 hinged to the operating handle 5, a mounting block 52 threadedly connected to the pipe body 2, and a first return spring 53. The top of the trigger 51 abuts against a first push plate 511. The first push plate 511 has a first through hole 6 for the push rod 11 to pass through. The push rod 11 passes through the first through hole 6 and the mounting block 52 in sequence and extends into the inner cavity of the pipe body 2. The first return spring 53 is disposed between the first push plate 511 and the mounting block 52. When the trigger 51 swings away from the pipe body 2, the trigger 51 pushes the first push plate 511, causing the first push plate 511 to tilt towards the push head 12. During use, the repair personnel grip the trigger 51 tightly to drive it away from the pipe body 2, so that the first push plate 511 tilts towards the push head 12 and locks onto the push rod 11. Thus, the first push plate 511 can push the push rod 11 into the inner cavity of the pipe body 2 and compress the first return spring 53. When the repairman releases his hand, the first return spring 53 pushes the first push plate 511 so that the first push plate 511 is perpendicular to the push rod 11, thereby releasing the engagement between the first push plate 511 and the push rod 11, and resetting the trigger 51 and the first push plate 511.

[0038] In some implementations, please refer to Figure 5 As shown, the operating handle 5 also includes a second return spring 54 and a second push plate 55 capable of swinging towards the tube body 2. The second push plate 55 has a second through hole 551 for the push rod 11 to pass through. The second return spring 54 supports the second push plate 55 tilted towards the end of the push rod 11 away from the push head 12, and makes the second push plate 55 abut against the rod body of the push rod 11. By supporting the second push plate 55 tilted towards the end of the push rod 11 away from the push head 12 by the second return spring 54, the push head 12 can only be inserted into the inner cavity of the tube body 2, preventing the push rod 11 from retracting due to the pressure inside the tube body 2 during the trigger 51 reset process. Of course, when it is necessary to withdraw the push rod 11, it is only necessary to press the second push plate 55 to compress the second return spring 54, so that the second push plate 55 is perpendicular to the push rod 11, that is, the axis of the second through hole 551 is parallel to the axis of the push rod 11, thus releasing the unidirectional output restriction of the push rod 11 by the second push plate 55. After the pressure on the second push plate 55 is removed, the second return spring 54 will drive the second push plate 55 to reset, so as to re-establish the unidirectional output restriction of the second push plate 55 on the push rod 11.

[0039] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
