[0021] See also Figures 1 to 3 The utility model provides a technical solution: a device for reducing crucible loss during calcination of magnesium oxide, comprising: a bottom plate 7, a support frame 6 is arranged in the middle of one side of the top of the bottom plate 7, a calcination device 5 is arranged in the middle of one side of the top of the bottom plate 7; a crucible limiting mechanism 4, the crucible limiting mechanism 4 comprises a slide rail 41, a slide rail 41 is symmetrically fixedly installed on one side of the top of the slide rail 41, a slider 42 is symmetrically slidably installed on the top of the slide rail 41, a movable frame 413 is fixedly installed on the top of the slider 42 on the same side, and a movable frame 413 is fixedly installed in the middle of the top of the movable frame 413 There is an arc-shaped limit plate 412, a second slide rail 46 is fixedly installed in the middle of the other side of the top of the bottom plate 7, a second slider 44 is slidably installed on the top of the second slide rail 46, a connecting plate 410 is fixedly installed on the top of the second slider 44, a connecting rod 43 is symmetrically rotatably installed on one side of the connecting plate 410, and the connecting rod 43 is rotatably installed on the other side of the movable frame 413 on the same side away from the side of the connecting plate 410, and a pin shaft 411 is rotatably installed in the middle of the connecting rod 43, and the pin shaft 411 is symmetrically fixedly installed on the other side of the middle of the top of the bottom plate 7; the crucible body 3, the crucible body 3 is arranged at The arc-shaped limiting plates 412 are close to each other on one side, and the staff places the magnesium oxide material in the crucible body 3, and then places the crucible body 3 on the support frame 6. At this time, the piston rod in the electric push rod 45 moves into the inner cavity of the electric push rod 45, and the slider 44 moves along the slide rail 46, and then the connecting rod 43 rotates with the pin shaft 411. At this time, the movable frame 413 cooperates with the slider 1 42 to approach each other on the surface of the slide rail 1 41, and then the arc-shaped limiting plate 412 limits and fixes the crucible body 3, which can ensure that the crucible body 3 is fixed during calcination. The stability during the calcination process can be ensured to prevent the crucible body 3 from falling from the support frame 6 and affecting the calcination of the magnesium oxide material. Ball bearings are arranged inside the slider 1 42 and the slider 2 44, which can convert the sliding friction between the slider 1 42, the slider 2 44, the slide rail 1 41 and the slide rail 2 46 into rolling friction, which is beneficial to improving the moving smoothness of the slider 1 42 and the slider 2 44. After the crucible body 3 is fixed, the calcination equipment 5 can be used to heat and calcine the crucible body 3, thereby realizing the calcination of the magnesium oxide raw material in the crucible body 3.

[0022] The top of the crucible body 3 is symmetrically fixed with a support ear 2, and the other side of the top of the bottom plate 7 is fixedly installed with a protective shell 1. The front and rear sides of the protective shell 1 are provided with a plurality of evenly distributed slots 8. Since the upper part of the crucible body 3 is provided with a support ear 2, after the calcination is completed, the staff can use external auxiliary tools to remove the crucible body 3 to avoid external auxiliary tools clamping the inside of the crucible body 3, causing the internal protective layer of the crucible body 3 to be worn, affecting the service life of the crucible body 3. An electric push rod 45 is fixed to the front of the other side of the top of the bottom plate 7. The driving end of the electric push rod 45 is fixedly installed in the middle of the front side of the slider 44. A limit baffle 47 is fixedly installed on the part, and a guide rod 49 is slidably installed in the middle of the limit baffle 47. The end of the guide rod 49 away from the limit baffle 47 is fixedly installed in the middle of the other side of the connecting plate 410, and a limit block is fixedly installed on the other end of the guide rod 49. A spring 48 is fixedly installed in the middle of the other side of the connecting plate 410, and the end of the spring 48 away from the connecting plate 410 is fixedly installed in the middle of one side of the limit baffle 47. By setting the guide rod 49, when the slider 2 44 drives the connecting plate 410 to move, the guide rod 49 will slide inside the limit baffle 47, and then cooperate with the spring 48 to increase the movement stability of the slider 2 44.

[0023] During actual use, the staff adds an appropriate amount of magnesium oxide raw material into the crucible body 3, and then places the crucible body 3 on the support frame 6. Then, by controlling the electric push rod 45, the slider 44 will move along the slide rail 46, and then the connecting rod 43 will rotate in conjunction with the pin shaft 411. At this time, the movable frame 413 cooperates with the slider 1 42 to approach each other on the surface of the slide rail 1 41, and then the arc-shaped limiting plate 412 will limit and fix the crucible body 3, which can ensure the stability of the crucible body 3 during the calcination process and prevent the crucible body 3 from falling from the support frame 6, which affects the calcination of the magnesium oxide material. After the crucible body 3 is limited, the calcination equipment 5 can be used to heat and calcine the crucible body 3, so as to calcine the magnesium oxide raw material in the crucible body 3. After the calcination is completed, the electric push rod 45 cooperates with the slider 1 42, the slider 2 44 and the connecting rod 43 to separate the movable frame 413 from each other, so as to release the limit of the crucible body 3. At this time, the staff can remove the crucible body 3 by using external auxiliary tools in combination with the support ears 2, so as to avoid the external auxiliary tools directly contacting the surface of the crucible body 3, causing wear on the protective layer of the crucible body 3, and improving the service life of the crucible body 3.

[0024] Although the above describes the illustrative specific implementation methods of the present application so that technicians in this technical field can understand the present application, the present application is not limited to the scope of the specific implementation methods. For ordinary technicians in this technical field, as long as various changes are within the spirit and scope of the present application defined and determined by the attached claims, all application creations using the concept of the present application are protected.
