Description

Technical Field

[0001] This utility model relates to the technical field of silicon monoxide production equipment, specifically to a vacuum resistance furnace. Background Technology

[0002] With the development of science and technology, the manufacturing field has put forward higher requirements for lithium-ion battery materials. Among them, silicon monoxide has always been a key research direction. Although silicon monoxide has good electrochemical performance, the preparation method of silicon monoxide is too harsh and the equipment requirements are high. It is necessary to convert the raw materials silicon and silicon dioxide into silicon monoxide vapor under certain temperature and vacuum conditions, and then condense it to finally prepare silicon monoxide material. In the current technology, vacuum resistance furnace is often used to prepare silicon monoxide material.

[0003] Chinese utility model patent document CN217504369U discloses a vacuum resistance furnace for high-efficiency production of silicon monoxide. This device uses a first electric cylinder mounted on the top of a support base to extract a finished product collector from the furnace body. A first motor mounted on the bottom of a fixed plate drives a power gear to mesh with a rotating gear, thus rotating the finished product collector. A power mechanism mounted between the two base plates drives a slide to slide to the right on a slide rod, causing the fixed plate connected to the left end of the base to tilt downwards. The tilt angle is adjusted by a second electric cylinder mounted on the top of a rotating block, facilitating the extraction of silicon monoxide by the operator. This method is time-saving, labor-saving, and highly flexible. However, the finished product collector used for silicon monoxide condensation cannot be disassembled during use, meaning that silicon monoxide can only be extracted from the collector before the next silicon monoxide preparation can begin, affecting work efficiency. Furthermore, the finished product collector is directly exposed to the outside environment during silicon monoxide extraction, causing the silicon monoxide to be exposed to air throughout the extraction process, affecting the purity of the silicon monoxide product. Utility Model Content

[0004] The purpose of this invention is to provide a vacuum resistance furnace that solves the problem in the prior art where the finished product collector for condensing silicon monoxide in the vacuum resistance furnace cannot be disassembled, resulting in the need to extract silicon monoxide from the finished product collector before the next silicon monoxide preparation can be carried out, thus affecting work efficiency.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A vacuum resistance furnace includes a frame and a vacuum resistance furnace body located at the top of the frame. One end of the vacuum resistance furnace body has a furnace opening. A sealing plate for closing the furnace opening is located at the top of the frame near the furnace opening via a drive assembly. A finished product collector is detachably installed on the side of the sealing plate facing the furnace opening. A connecting groove is formed on the side of the sealing plate facing the furnace opening. Limiting grooves communicating with the connecting groove are symmetrically arranged on the left and right sides of the connecting groove on the sealing plate. A connecting block is inserted into the connecting groove. Limiting blocks inserted into the limiting groove are symmetrically arranged on the left and right sides of the connecting block on the limiting groove. The side of the connecting block facing the furnace opening is fixedly connected to the finished product collector. A locking assembly for preventing the limiting block from sliding out of the limiting groove is located above each limiting groove on one side of the sealing plate.

[0006] A further technical solution is that the drive assembly includes a lead screw and a servo motor. Two guide rails are symmetrically arranged on the top of the frame near the furnace opening. A slider is slidably connected on each guide rail. The top of the sliders are connected to the same mounting plate. The side of the mounting plate facing the furnace opening is fixedly connected to the sealing plate. The lead screw is rotatably located between the two guide rails, and a drive block is threadedly connected to its outer side. The top side of the drive block is fixedly connected to the top side of the mounting plate. The servo motor is located at one end of the top of the frame, and its output shaft is drivenly connected to one end of the lead screw.

[0007] A further technical solution is that the locking assembly includes a locking element, and a sealing plate located above the limiting groove is rotatably connected to a rotating bolt via a bearing. The end of the rotating bolt facing the furnace opening is fixedly connected to one end of the locking element, so that the other end of the locking element is set vertically downward.

[0008] A further technical solution is that the top side wall of the limiting groove has an installation port, the other end of the rotating bolt rotates and passes into the installation port, and a cam is fixedly sleeved on its outer side. The cam's protrusion faces the same direction as the end of the locking member away from the rotating bolt. When the end of the locking member away from the rotating bolt is set vertically downward, the cam's protrusion protrudes from the installation port and is placed in the limiting groove.

[0009] A further technical solution is that a sealing ring is provided at one end of the vacuum resistance furnace body to surround the furnace opening, and a sealing ring groove is provided on the side of the sealing plate facing the furnace opening to surround the connecting groove, and the ring diameter of the sealing ring is the same as the ring diameter of the sealing ring groove.

[0010] Compared with the prior art, the beneficial effects of this utility model are: In use, this invention uses a drive assembly to move a sealing plate away from the open furnace opening. The finished product collector, mounted on the sealing plate, moves out of the vacuum resistance furnace along with the sealing plate. At this point, the locking assembly is unlocked, no longer obstructing the limiting block. Pulling the finished product collector then slides the connecting block out of the connecting groove, and simultaneously, the limiting block slides out of the limiting groove. This allows the condensed finished product collector to be removed and transferred to a glove box (filled with inert gas), facilitating subsequent powder collection and packaging in an oxygen-free and water-free environment. This prevents silicon monoxide from being exposed to air throughout the extraction process, which would affect the purity of the silicon monoxide product. Furthermore, after removing the condensed finished product collector, another finished product collector can be installed before silicon monoxide preparation can proceed. This avoids the inefficiency of existing technologies where silicon monoxide extraction from the finished product collector must be completed before the next silicon monoxide preparation can begin.

Detailed Implementation

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0016] All electrical components involved in this application are prior art. Those skilled in the art understand their connection methods. With the help of those skilled in the art, all electrical components in this application and their compatible power supplies can be connected by wires. According to the actual situation, a suitable controller can be selected to meet the control requirements. For specific connections and control sequences, please refer to the description below. The electrical connection between each electrical component is completed in the order of operation. The detailed connection methods are well known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control.

[0017] Example 1: Reference Figures 1 to 3 This utility model discloses a vacuum resistance furnace, comprising a frame 1 and a vacuum resistance furnace body 2 disposed at the top of the frame 1. One end of the vacuum resistance furnace body 2 has a furnace opening. A heating layer is provided on the inner side wall of the end of the vacuum resistance furnace body 2 away from the furnace opening, so that the heating layer serves as a reaction zone. Simultaneously, a vacuum pump is connected to the end of the vacuum resistance furnace body 2 away from the furnace opening. These are all common technical knowledge to those skilled in the art, and those skilled in the art can directly obtain the corresponding installation relationships and structures based on common knowledge, so they will not be elaborated further here. A sealing plate 3 for closing the furnace opening is provided at the top end of the frame 1 near the furnace opening via a drive assembly. A finished product collector 4 is detachably installed on the side of the sealing plate 3 facing the furnace opening. A connecting groove 5 is opened on the side of the sealing plate 3 facing the furnace opening. A limiting groove 6 connected to the connecting groove 5 is symmetrically arranged on the left and right sides of the sealing plate 3. A connecting block 7 is inserted into the connecting groove 5. A limiting block 8 inserted into the limiting groove 6 is symmetrically arranged on the left and right sides of the connecting block 7. The side of the connecting block 7 facing the furnace opening is fixedly connected to the finished product collector 4. A locking component is provided on one side of the sealing plate 3 above each limiting groove 6 to prevent the limiting block 8 from sliding out of the limiting groove 6. It should be noted that there are multiple finished product collectors 4 connected with connecting blocks 7.

[0018] In this embodiment, the driving component moves the sealing plate 3 to open the unclosed furnace opening, allowing raw materials to be added into the vacuum resistance furnace body 2. Then, the driving component moves the sealing plate 3 to close the furnace opening, and simultaneously, the finished product collector 4 mounted on the sealing plate 3 is placed inside the vacuum resistance furnace body 2. At this point, silicon monoxide can be prepared. After preparation, the driving component moves the sealing plate 3 to open the unclosed furnace opening, and the finished product collector 4, mounted on the sealing plate 3, moves out of the vacuum resistance furnace along with the sealing plate 3. At this point, the locking component is unlocked, no longer obstructing the limiting block 8, and then pulling the finished product collector 4 will connect the connecting block 7. The collector 4 containing the condensed finished product can be disassembled and transferred to a glove box (filled with inert gas) after sliding out of the connecting groove 5 and the limiting block 8 sliding out of the limiting groove 6. This facilitates the subsequent collection and packaging of powder in an oxygen-free and water-free environment, preventing silicon monoxide from being exposed to air throughout the extraction process and affecting the purity of the silicon monoxide product. After disassembling the collector 4 containing the condensed finished product, another collector 4 can be installed before silicon monoxide preparation can proceed. This avoids the situation in the existing technology where silicon monoxide can only be extracted from the collector 4 before the next silicon monoxide preparation can be carried out, which affects work efficiency.

[0019] Example 2 Based on Example 1, referring to Figures 1 to 3 The drive assembly includes a lead screw 9 and a servo motor 10. Two guide rails 11 are symmetrically arranged on the top of the frame 1 near the furnace opening. A slider 12 is slidably connected to each guide rail 11. The top of the sliders 12 is connected to the same mounting plate 13. The side of the mounting plate 13 facing the furnace opening is fixedly connected to the sealing plate 3. The lead screw 9 is rotatably located between the two guide rails 11, and a drive block 14 is threadedly connected to its outer side. The top side of the drive block 14 is fixedly connected to the top side of the mounting plate 13. The servo motor 10 is located at one end of the top of the frame 1, and its output shaft is drivenly connected to one end of the lead screw 9.

[0020] In this embodiment, when it is necessary to drive the sealing plate 3 to move, the servo motor 10 is controlled to work, the servo motor 10 drives the lead screw 9 to rotate, the lead screw 9 engages with the drive block 14 threadedly, so that the drive block 14 moves along the central axis of the lead screw 9, the drive block 14 drives the mounting plate 13 to move, and then drives the sealing plate 3 to move. By setting the cooperation between the guide rail 11 and the slider 12, the stability of the movement of the mounting plate 13 is ensured.

[0021] Example 3 Based on Example 1, referring to Figure 1 The locking assembly includes a locking element 15. The sealing plate 3 is located above the limiting groove 6 and is rotatably connected to a rotating bolt 17 via a bearing 16. One end of the rotating bolt 17 facing the furnace opening is fixedly connected to one end of the locking element 15 so that the other end of the locking element 15 is set vertically downward.

[0022] In this embodiment, when installing the finished product collector 4, the locking member 15 is rotated so that the end of the locking member 15 away from the rotating bolt 17 is set in a direction away from the center of the sealing plate 3. Then, the connecting block 7 is inserted into the connecting groove 5, and the limiting block 8 is inserted into the limiting groove 6. The locking member 15 is rotated so that the bottom end of the locking member 15 is vertically downward. Since the locking member 15 has its own weight, the bottom end of the locking member 15 will naturally be set vertically downward, blocking the limiting block 8 and preventing the limiting block 8 from sliding out of the limiting groove 6.

[0023] As a preferred embodiment, refer to Figure 1 The top side wall of the limiting groove 6 is provided with an installation port 18. The other end of the rotating bolt 17 rotates and passes into the installation port 18, and a cam 19 is fixedly sleeved on its outer side. The convex head of the cam 19 faces the same direction as the end of the locking member 15 away from the rotating bolt 17. When the end of the locking member 15 away from the rotating bolt 17 is set vertically downward, the convex head of the cam 19 protrudes from the installation port 18 and is placed in the limiting groove 6.

[0024] Specifically, when the connecting block 7 is inserted into the connecting groove 5 and the limiting block 8 is inserted into the limiting groove 6, rotating the locking member 15 so that its bottom end is vertically downward will drive the rotating bolt 17 to rotate. The rotation of the rotating bolt 17 will drive the convex head of the cam 19 to rotate and be placed in the limiting groove 6. At this time, the convex head of the cam 19 abuts against the limiting block 8, thereby limiting the limiting block 8. At the same time, since the cam 19 is fixedly sleeved on the rotating bolt 17, the convex head of the cam 19 abuts against the limiting block 8, causing the cam 19 to be subjected to friction, thereby limiting the rotating bolt 17, making it difficult for the rotating bolt 17 to rotate. Finally, the locking member 15 is limited, ensuring that the bottom end of the locking member 15 is set vertically downward, and the limiting block 8 is blocked stably.

[0025] Example 4 Based on Example 1, referring to Figure 1 A sealing ring is provided at one end of the vacuum resistance furnace body 2 to surround the furnace opening. A sealing ring groove 20 is provided on the side of the sealing plate 3 facing the furnace opening to surround the connecting groove 5, and the ring diameter of the sealing ring is the same as the ring diameter of the sealing ring groove 20.

[0026] In this embodiment, by setting a sealing ring and a sealing ring groove 20, when the sealing plate 3 closes the furnace opening, the sealing ring is placed in the sealing ring groove 20, so that the sealing ring is tightly fitted with the groove wall of the sealing ring groove 20, thus ensuring the sealing performance.

[0027] Although the present invention has been described herein with reference to several illustrative embodiments, it should be understood that many other modifications and implementations can be devised by those skilled in the art, which will fall within the scope and spirit of the principles disclosed herein. More specifically, various variations and modifications can be made to the components and / or layout of the subject matter combination within the scope of the disclosure, drawings, and claims. Besides variations and modifications to the components and / or layout, other uses will be apparent to those skilled in the art.
