Description

Technical Field

[0001] This utility model relates to the field of ceramic material production equipment, and in particular to an observation device for a ceramic material sintering pusher furnace. Background Technology

[0002] Pusher furnaces are high-temperature material preparation equipment, especially continuous heat treatment equipment in fields such as ceramics, powder metallurgy, and refractory materials. Pusher furnaces are typically equipped with observation devices to monitor the smooth flow of products within the furnace chamber during operation. However, most existing observation mirrors are directly mounted on the side wall of the pusher furnace. During operation, volatile tar substances are often generated, which can accumulate on the observation mirror as they disperse within the furnace, hindering the observation of the furnace's internal conditions. Summary of the Invention

[0003] The purpose of this invention is to provide an observation device for a ceramic material sintering pusher furnace, which can effectively prevent the observation mirror from being contaminated by the gas inside the furnace and thus affecting the observation effect.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: an observation device for a ceramic material sintering pusher furnace, used to observe the state of products inside the pusher furnace, comprising:

[0005] Mounting plate, the mounting plate being embedded in the side wall of the pusher furnace or being the side wall of the pusher furnace;

[0006] An observation tube is mounted on the mounting plate, with one end connected to the mounting plate being the proximal end and the other end being the distal end;

[0007] An observation mirror is mounted on the distal end of the observation tube;

[0008] The protective mechanism includes an air inlet pipe located on the circumferential surface of the proximal end of the observation tube, and an air source for supplying inert gas into the air inlet pipe.

[0009] Another implementation method is that the observation device for the ceramic material sintering pusher furnace includes a gate valve installed on the observation tube and used to control the on / off state of the proximal or distal end of the observation tube. After the pusher furnace has been running for a long time, a small amount of tar material may still adhere to the observation mirror. Close the gate valve to lock the gas in the pusher furnace, then remove and clean the observation mirror. After cleaning, reinstall the observation mirror and open the gate valve to continue using it.

[0010] Another implementation method is that the observation mirror includes a sealing cap threaded to the distal end of the observation tube, and a mirror body pressed by the sealing cap onto the distal end of the observation tube. The sealing cap has a through hole in the middle of its end face, and the mirror body is sealed to the distal end of the observation tube. The mirror body is made of tempered glass, and under the protection of inert gas, the working conditions inside the pusher furnace can be clearly observed through the through hole and the mirror body.

[0011] Another implementation method is to provide a first sealing ring between the mirror body and the distal end face of the observation tube; this can ensure that the observation mirror is in a sealed state and thus does not affect the atmosphere inside the furnace, maintaining the stability of the atmosphere inside the furnace.

[0012] Another implementation method is to provide a second sealing ring between the inner side of the end face of the sealing cap and the mirror body; this can further ensure that the observation mirror is in a sealed state and thus not affect the atmosphere inside the furnace, maintaining the stability of the atmosphere inside the furnace.

[0013] Another implementation method is that the observation tube includes a first tube body and a union connector. One end of the first tube body is connected to the mounting plate, and this end is the proximal end. The other end of the first tube body is threadedly connected to one end of the union connector, and the other end of the union connector is connected to one end of the gate valve.

[0014] Another implementation method is that the observation tube includes a second tube body with one end threadedly connected to the other end of the gate valve, the other end of the second tube body being the distal end of the observation tube, and the observation mirror being threadedly connected to the other end of the second tube body; by setting a union joint, the gate valve and the first tube body can be quickly installed, and the distance between the observation mirror and the side wall of the pusher furnace can be adjusted, so that the observation mirror is in a position that is easy to observe.

[0015] Another implementation method is to form a raised ring on the circumferential surface of the second tube. The raised ring can prevent the second tube from being over-screwed into the gate valve and causing stripping, and can also prevent the observation scope from being over-screwed into the second tube and causing the scope body to break and be damaged.

[0016] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art: During the operation of the pusher furnace, inert gas is continuously introduced into the observation tube through the air inlet pipe at the near end of the observation tube to form a section of air curtain, preventing tar substances from adhering to the observation mirror and affecting the observation of the working conditions inside the pusher furnace.

[0022] Mounting plate 4 is embedded in the side wall of the pusher furnace or is the side wall of the pusher furnace; observation tube 1 is provided on mounting plate 4, with one end connected to mounting plate 4 as proximal end A and the other end as distal end B; observation mirror 2 is installed on the distal end of observation tube 1; the protection mechanism includes an air inlet pipe 31 provided on the circumferential surface of the proximal end of observation tube 1, and a gas source for providing inert gas into air inlet pipe 31 (the gas source can be a gas storage tank containing inert gas, connected to air inlet pipe 31 through a pipe; the gas source is not the focus of this utility model and will not be described in detail here). During the operation of the pusher furnace, Volatile tar substances are usually produced, which can stick to the observation mirror 2 when diffused in the furnace. In order to isolate the tar substances, inert gas is continuously introduced into the observation tube 1 through the air inlet pipe 31 near the end of the observation tube 1 during the operation of the pusher furnace, forming a gas curtain to prevent the tar substances from sticking to the observation mirror 2 and affecting the observation of the working conditions inside the pusher furnace. The air inlet pipe 31 can also be tangent to the inner wall of the observation tube 1, forming a cyclone barrier on both sides of the axis position of the observation tube 1 at the intersection of the air inlet pipe 31 and the side wall of the observation tube 1, thereby improving the blocking effect of the inert gas.

[0023] Specifically: Gate valve 5 is installed on observation tube 1 and is used to control the opening and closing of the near or far end of observation tube 1; after the pusher furnace has been running for a long time, a small amount of tar material may still adhere to the observation mirror 2. Close gate valve 5 to lock the gas in the pusher furnace, then remove and clean the observation mirror 2. After cleaning, reinstall the observation mirror 2 and open gate valve 5 for continued use; The observation mirror 2 includes a sealing cap 21 threaded to the far end of observation tube 1, and a mirror body 22 pressed by the sealing cap 21 onto the far end of the observation tube 1 at the tube opening 10. The end face of the sealing cap 21 has a through hole 23 in the middle, and the mirror body 22 is sealed to the far end of the observation tube 1 at the tube opening 10; The mirror body 22 is made of tempered glass, and under the protection of inert gas, the working conditions inside the pusher furnace can be clearly observed through the through hole 23 and the mirror body 22; A first sealing ring 24 is provided between the mirror body 22 and the end face of the far end of observation tube 1; This ensures that the observation mirror 2 is in a sealed state and does not affect the atmosphere inside the furnace. Maintaining a stable atmosphere inside the furnace; a second sealing ring 25 is provided between the inner side of the end face of the sealing cap 21 and the mirror body 22; this can further ensure that the observation mirror 2 is in a sealed state and thus does not affect the atmosphere inside the furnace, maintaining a stable atmosphere inside the furnace; the observation tube 1 includes a first tube body 11, a union joint 14, and a second tube body 12. One end of the first tube body 11 is connected to the mounting plate 4, and this end is the proximal end; the other end of the first tube body 11 is threadedly connected to one end of the union joint 14, and the other end of the union joint 14 is connected to one end of the gate valve 5. One end of the second tube body 12 is threadedly connected to the other end of the gate valve 5, and the other end of the second tube body 12 is the distal end of the observation tube 1. The observation mirror 2 is threadedly connected to the other end of the second tube body 12; by setting the union joint 14, the gate valve 5 and the first tube body 11 can be quickly installed, and the distance between the observation mirror 2 and the side wall of the pusher furnace can be adjusted, so that the observation mirror 2 is in a position that is easy to observe. A raised ring 13 is formed on the circumferential surface of the second tube 12. The cross-section of the raised ring 13 is approximately hexagonal, which facilitates the rotation of the second tube 12. The raised ring 13 can prevent the second tube 12 from being over-screwed into the gate valve 5 and causing stripping, and can also prevent the observation mirror 2 from being over-screwed into the second tube 12 and causing the mirror body 22 to break and be damaged.
