Description

Technical Field

[0001] The utility model relates to the technical field of silicon monoxide production, in particular to a device for continuous production of silicon monoxide. Background Art

[0002] Silicon monoxide (SiO) is an important inorganic compound and is widely used in the fields of fine ceramic synthesis, optical glass and semiconductor material preparation. At present, the mainstream method for preparing silicon monoxide in industry is to use silicon dioxide (SiO2) and elemental silicon (Si) to react in a high temperature vacuum environment to generate silicon monoxide. Although this method can achieve the preparation of silicon monoxide, it has significant limitations in the actual production process.

[0003] First, after silicon dioxide reacts with elemental silicon in a high-temperature vacuum environment, the generated silicon monoxide exists in a vapor state. After the reaction is completed, it is necessary to wait for the reactor to cool down so that the vapor silicon monoxide gradually condenses into a solid state. This cooling process is not only time-consuming, resulting in low production efficiency, but also more troublesome to remove and clean the silicon monoxide solidified in the reactor, which increases energy consumption and production costs. Secondly, in the prior art, the production of silicon monoxide usually adopts an intermittent production method, that is, after completing a batch of production in a reactor, it is necessary to shut down, clean, reload, and then produce the next batch. This production method cannot achieve continuous production, further reduces production efficiency, and increases the complexity of equipment maintenance. For the problems in the related art, no effective solution has been proposed yet. Therefore, it is necessary to propose a device for continuous production of silicon monoxide to solve the above-mentioned problems. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the existing production method cannot realize continuous production, thereby reducing the production efficiency.

[0005] In order to solve the above technical problems, a technical solution provided by the utility model is:

[0006] A device for continuous production of silicon monoxide includes a reactor body, characterized in that: a feed pipe is fixedly connected to the top of the reactor body, a storage barrel is fixedly connected to the top of the feed pipe, a reaction plate is slidably installed inside the reactor body, a ventilation groove is opened on the surface of the reaction plate, sealing plates are rotatably installed on both sides of the ventilation groove, a blocking plate is fixedly connected to one side of the sealing plate, a limiting groove is opened on the surface of the reaction plate, the limiting groove cooperates with the blocking plate, a sliding groove is opened on the bottom surface of the sealing plate, a transmission block is slidably installed inside the sliding groove, a support frame is fixedly installed on the bottom surface of the transmission block, electric telescopic rods are fixedly installed on both sides of the bottom of the reactor body, the top of the electric telescopic rods slides through the bottom surface of the reactor body and is rotatably connected to the support frame, an exhaust hole is opened on the bottom surface of the reactor body, and a condensing device is installed on one side of the exhaust hole.

[0007] Furthermore, the condensing device includes an exhaust pipe fixedly connected to one side of the exhaust hole, the end of the exhaust pipe is fixedly connected to a condensing box, a water cooling pipe is fixedly installed on the inner wall of the condensing box, and a closing cover is rotatably installed on the top of the condensing box.

[0008] Furthermore, a loading cover is slidably mounted on the top of the storage barrel.

[0009] Furthermore, a feed valve is installed on the surface of the feed pipe, and an exhaust valve is installed on the surface of the exhaust pipe.

[0010] Furthermore, a stabilizing frame is fixedly connected to the bottom surface of the reactor body, and a supporting plate is fixedly connected to the bottom end of the electric telescopic rod.

[0011] Furthermore, one side surface of the material storage barrel, the reaction furnace body and the condensation box is fixedly connected with a vacuum exhaust pipe, and a sealing valve is fixedly installed on the surface of the vacuum exhaust pipe.

[0012] Furthermore, a heating resistor is fixedly mounted on the inner wall of the reaction furnace body.

[0013] The beneficial effects of the utility model are:

[0014] The material to be reacted is placed on the reaction plate at the bottom of the reactor body, and vapor silicon monoxide is generated through high temperature and high pressure. At this time, the electric telescopic rod is started to extend, so that the electric telescopic rod drives the reaction plate to move upward in the reactor body by pushing the sealing plate. The rotatably installed sealing plate rotates upward after being pushed, so that the ventilation groove on the reaction plate is opened. After the reaction plate moves upward, the vapor silicon monoxide moves to the bottom of the reaction plate through the ventilation groove. When the reaction plate moves to the top of the reactor body, the electric telescopic rod contracts and drives the sealing plate to rotate downward. Through the mutual cooperation of the upper limit groove and the blocking plate on the reaction plate, the sealing plate rotates and seals the ventilation groove, so that when the reaction plate moves downward, the vapor silicon monoxide below is pushed into the condensing device for condensation and forming. When the reaction plate moves to the bottom of the reactor body, the material can be put into the reaction plate again to realize the continuous production of silicon monoxide, thereby effectively improving the production efficiency of silicon monoxide.

A pair of electric telescopic rods 12 are fixedly installed on both sides of the bottom of the reaction furnace body 1. The top of the electric telescopic rod 12 slides through the bottom surface of the reaction furnace body 1 and is rotatably connected to the support frame 11. The electric telescopic rod 12 is extended and retracted to drive the sealing plate 6 to rotate in the ventilation groove 5, and drive the reaction plate 4 to move up and down in the reaction furnace body 1; an exhaust hole 13 is opened on the bottom surface of the reaction furnace body 1, and a condensing device 14 is installed on one side of the exhaust hole 13 for condensing and molding the generated vapor-state silicon monoxide.

[0028] Among them, a loading cover 15 is slidably installed on the top of the storage barrel 3 for sealing the storage barrel 3; a discharge valve 16 is installed on the surface of the feed pipe 2 for controlling the falling of the reaction material in the storage barrel 3; an exhaust valve 17 is installed on the surface of the exhaust pipe 141 for controlling the emission of vapor silicon monoxide in the reactor body 1; a stabilizing frame 18 is fixedly connected to the bottom surface of the reactor body 1, and a support plate 19 is fixedly connected to the bottom end of the electric telescopic rod 12 to achieve stable support for the reactor body 1 and the electric telescopic rod 12 Example

[0029] like Figure 1 and Figure 5 As shown, this embodiment is obtained by further describing technical features such as the condensing device 14 on the basis of the embodiment one. The remaining technical features are the same as those of the embodiment one, and the similarities are not repeated here. The difference between this embodiment and the embodiment one lies in that: the condensing device 14 includes an exhaust pipe 141 fixedly connected to one side of the exhaust hole 13, and the end of the exhaust pipe 141 is fixedly connected to a condensing box 142, and a water-cooling pipe 143 is fixedly installed on the inner wall of the condensing box 142; a closing cover 144 is rotatably installed on the top of the condensing box 142 for opening and closing the condensing box 142; a vacuum exhaust pipe 20 is fixedly connected to the surface of one side of the storage barrel 3, the reactor body 1 and the condensing box 142, and a heating resistor 22 is fixedly installed on the inner wall of the reactor body 1 for realizing high-temperature heating in the reactor body 1.

[0030] In this embodiment, the water cooling pipe 143 is used to maintain a low temperature inside the condensing box 142 after the cold water is connected. A sealing valve 21 is fixedly installed on the surface of the vacuum exhaust pipe 20 to achieve vacuum suction in the storage barrel 3, the reactor body 1 and the condensing box 142.

When the reaction plate 4 moves to the top of the reactor body 1, the electric telescopic rod 12 is contracted and drives the sealing plate 6 to rotate downward. Through the mutual cooperation of the upper limit groove 8 and the blocking plate 7 on the reaction plate 4, the sealing plate 6 rotates to seal the ventilation groove 5, and then the reaction plate 4 moves downward to push the vapor-state silicon monoxide below into the condensing device 14 for condensation and molding.
