It can be used in high-temperature structural materials and superconducting materials.

[0003] In response, Chinese patent application number CN202322278852.4 discloses a titanium nitride preparation apparatus, comprising: a furnace body with a furnace door movably mounted on its front; a movable structure mounted on the inner side of the furnace body, the movable structure including a fixed block fixedly mounted on the bottom surface of the inner side of the furnace body, a first ceramic roller movably mounted on the top surface of the fixed block via a bearing, a slide rail mounted on one side of the fixed block, a slider slidably mounted on the top surface of the slide rail, a rack plate fixedly connected to the bottom surface of the slider, a rotating block movably mounted on the top surface of the slider via a rotating shaft, and a motor fixedly mounted on the rear wall of the furnace body. This invention, by setting a rotating block on the slider, allows the movement of a graphite boat via the rotating block, enabling convenient automatic removal or placement from the furnace body, improving the ease of graphite boat movement and ensuring the safety of the apparatus.

[0004] The device uses a slider and a rotating block to transport and fix the graphite boat inside and outside the furnace. However, the slider needs to penetrate through the left wall of the furnace, and the heat inside the furnace will dissipate through the penetration, increasing energy consumption. In addition, the hot slider may cause burns when it extends, reducing the user experience of the device.

[0005] Therefore, in order to solve the above problems, a titanium nitride preparation apparatus is proposed. Utility Model Content

[0006] The purpose of this invention is to provide a titanium nitride preparation apparatus to solve the problems mentioned in the background art. In the prior art, the apparatus can transport and fix the graphite boat inside and outside the furnace by means of a slider and a rotating block. However, the slider needs to penetrate through the left wall of the furnace, and the heat inside the furnace will be dissipated through the penetration, which increases energy consumption. In addition, when the hot slider is extended, there is a risk of burns, which reduces the user experience of the apparatus.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a titanium nitride preparation apparatus, comprising: a furnace body, a sliding door installed on the right side wall of the furnace body, a first fixing plate installed on the inner side of the furnace body, a first roller installed on the top surface of the first fixing plate, a second fixing plate fixedly installed on the right side of the furnace body, and a second roller installed on the top surface of the second fixing plate;

[0008] A positioning structure is installed on the inner side of the furnace body. The positioning structure includes a graphite boat, which is movably mounted on the top surface of the first roller. An inclined block is fixedly mounted on the bottom surface of the graphite boat, and a slot is opened on the bottom surface of the inclined block. A fixing block is fixedly mounted on the inner side of the furnace body. A first insertion hole is opened on the surface of the fixing block. An insertion block is slidably mounted on the inner side of the fixing block. A second insertion hole is opened on the surface of the insertion block. A spring is fixedly connected to the bottom surface of the insertion block. A support block is fixedly mounted on the top surface of the second fixing plate. A motor is fixedly connected to the surface of the second fixing plate. A threaded rod is fixedly connected to the output end of the motor. A wedge is threadedly connected to the outer side of the threaded rod.

[0009] A push-pull structure is installed on the positioning structure. The push-pull structure includes a fixing frame, which is fixedly installed on the right side wall of the graphite boat. A slot is opened on the surface of the fixing frame, and an L-shaped push-pull rod is inserted into the right side wall of the second fixing plate.

[0010] Preferably, the top surfaces of the first roller and the second roller are flush and aligned horizontally.

[0011] Preferably, the wedge, the first socket, and the second socket are adapted to each other, the upper end of the first socket communicates with the lower end of the second socket, and the upper end of the wedge is inserted into the slot.

[0012] Preferably, one end of the spring is fixedly connected to the inner wall of the fixing block.

[0013] Preferably, the wedge has a rectangular cross-section and is slidably mounted inside the support block.

[0014] Preferably, the L-shaped push-pull rod is adapted to the slot.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting an L-shaped push-pull rod that can be pushed and pulled, the graphite boat can be pushed into the furnace body or pulled out of the furnace body after the push-pull door is opened, without the need to drill holes on the surface of the furnace body again, which facilitates production and reduces the cost of use. In addition, by inserting the plug into the slot, the graphite boat can be fixed on the first roller, which improves the stability of the device.

[0016] This invention features a positioning structure and a push-pull structure. The graphite boat is placed on the second roller, and the L-shaped push-pull rod is pushed onto the surface of the fixing frame. Rotating the L-shaped push-pull rod causes its end to engage with the inner side of the slot. Continuing to push the L-shaped push-pull rod moves the graphite boat from the second roller to the first roller. As the graphite boat moves on the first roller, the top surface of the insert block rubs against the bottom surface of the inclined block, causing the insert block to retract into the fixing block and compress the spring. When the insert block is vertically aligned with the slot, it is inserted into the slot under the elastic force of the spring, thus fixing the graphite boat and preventing it from shaking inside the furnace. To remove the graphite boat, the motor is started. The motor drives the threaded rod to rotate, and the threaded rod is threadedly connected to the wedge. The rotation of the threaded rod causes the wedge to extend to the left, and the wedge extends into the furnace body and is inserted into the first and second insertion holes. The end of the wedge pushes the inner wall of the second insertion hole, causing the insertion block to descend within the fixed block. The insertion block is then pulled out of the slot, which releases the fixation of the graphite boat and re-locks the end of the L-shaped push-pull rod into the slot. Then, by pulling the L-shaped push-pull rod, the graphite boat can be removed from the furnace body and moved onto the second roller. This achieves convenient loading and unloading of the graphite boat without the need to drill holes in the furnace body, ensuring the furnace body's sealing while reducing energy consumption, and is safer and more practical.

[0024] The furnace body 1, sliding door 11, first fixing plate 12, first roller 13, second fixing plate 14, second roller 15, graphite boat 21 and motor 210 used in this application are products that can be directly purchased on the market. Their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be described in detail here.

[0025] A titanium nitride preparation apparatus includes: a furnace body 1, a sliding door 11 installed on the right side wall of the furnace body 1, a first fixing plate 12 installed on the inner side of the furnace body 1, a first roller 13 installed on the top surface of the first fixing plate 12, a second fixing plate 14 fixedly installed on the right side of the furnace body 1, and a second roller 15 installed on the top surface of the second fixing plate 14.

[0026] A positioning structure 2 is installed on the inner side of the furnace body 1. The positioning structure 2 includes a graphite boat 21, which is movably installed on the top surface of the first roller 13. An inclined block 22 is fixedly installed on the bottom surface of the graphite boat 21. A slot 23 is opened on the bottom surface of the inclined block 22. A fixing block 24 is fixedly installed on the inner side of the furnace body 1. A first insertion hole 25 is opened on the surface of the fixing block 24. An insertion block 26 is slidably installed on the inner side of the fixing block 24. A second insertion hole 27 is opened on the surface of the insertion block 26. A spring 28 is fixedly connected to the bottom surface of the insertion block 26. A support block 29 is fixedly installed on the top surface of the second fixing plate 14. A motor 210 is fixedly connected to the surface of the second fixing plate 14. A threaded rod 211 is fixedly connected to the output end of the motor 210. A wedge 212 is threadedly connected to the outer side of the threaded rod 211.

[0027] A push-pull structure 3 is installed on the positioning structure 2. The push-pull structure 3 includes a fixing frame 31, which is fixedly installed on the right side wall of the graphite boat 21. The surface of the fixing frame 31 is provided with a slot 32. An L-shaped push-pull rod 33 is inserted into the right side wall of the second fixing plate 14. The L-shaped push-pull rod 33 can be pushed and pulled. After the push-pull door 11 is opened, the graphite boat 21 can be pushed into the furnace body 1 or pulled out from the furnace body 1. There is no need to drill holes on the surface of the furnace body 1 again, which facilitates production and reduces the cost of use. In addition, the graphite boat 21 can be fixed on the first roller 13 by inserting the insert block 26 into the slot 23, which improves the stability of the device.

[0028] Furthermore, the top surfaces of the first roller 13 and the second roller 15 are flush and aligned left and right, allowing the graphite boat 21 to move back and forth on the first roller 13 and the second roller 15, facilitating the placement and removal of the graphite boat 21 within the furnace body 1.

[0029] Furthermore, the wedge 212, the first socket 25, and the second socket 27 are adapted to each other. The upper end of the first socket 25 communicates with the lower end of the second socket 27. The upper end of the plug 26 is inserted into the slot 23. The wedge 212 can be inserted into the first socket 25 and the second socket 27 so that the plug 26 descends in the fixing block 24 and is pulled out of the slot 23.

[0030] Furthermore, one end of the spring 28 is fixedly connected to the inner wall of the fixing block 24, and the spring 28 provides power for the insertion block 26 to be inserted into the fixing block 24, thereby fixing the graphite boat 21.

[0031] Furthermore, the wedge 212 has a rectangular cross-section and is slidably mounted inside the support block 29. The wedge 212 can slide stably within the support block 29 without rotating.

[0032] Furthermore, the L-shaped push-pull rod 33 is adapted to the slot 32, and the L-shaped push-pull rod 33 can be hooked in the slot 32 to push and pull the graphite boat 21.

[0033] Working principle: When in use, place the graphite boat 21 on the second roller 15, push the L-shaped push-pull rod 33 to push the L-shaped push-pull rod 33 to the surface of the fixed frame 31, and then rotate the L-shaped push-pull rod 33. The end of the L-shaped push-pull rod 33 will be locked inside the slot 32. Continue to push the L-shaped push-pull rod 33 to push the graphite boat 21 from the second roller 15 to the first roller 13. When the graphite boat 21 moves on the first roller 13, the top surface of the insert block 26 will rub against the bottom surface of the inclined block 22. The insert block 26 will then retract into the fixed block 24 and compress the spring 28. When the insert block 26 is aligned vertically with the slot 23, the insert block 26 will be inserted into the slot 23 under the elastic action of the spring 28, thus fixing the graphite boat 21 and preventing the graphite boat 21 from shaking inside the furnace body 1.

[0034] When the graphite boat 21 needs to be removed, the motor 210 is started. The motor 210 drives the threaded rod 211 to rotate. The threaded rod 211 is threadedly connected to the wedge block 212. The rotation of the threaded rod 211 causes the wedge block 212 to extend to the left, and the wedge block 212 extends into the furnace body 1 and is inserted into the first insertion hole 25 and the second insertion hole 27. The end of the wedge block 212 pushes the inner wall of the second insertion hole 27, causing the insertion block 26 to descend within the fixed block 24. The insertion block 26 then... Pulling out of the slot 23 releases the fixation of the graphite boat 21, and then locking the end of the L-shaped push-pull rod 33 back into the slot 32. Pulling the L-shaped push-pull rod 33 allows the graphite boat 21 to be removed from the furnace body 1, and the graphite boat 21 moves onto the second roller 15, enabling convenient loading and unloading of the graphite boat 21. This eliminates the need to drill holes in the furnace body 1, ensuring the sealing of the furnace body 1 while reducing energy consumption, and also improving safety and practicality.
