[0022] Please refer to Figure 1-6, the present utility model provides a technical solution: a device for preparing magnesium oxide, including a base 1. A calcination furnace body 2 is fixedly connected to the top of the base 1. The calcination furnace body 2 is an existing structure and will not be elaborated here in detail. For reference, please refer to the published patent: CN215626834U. Two symmetrical brackets 3 are fixedly connected to the top of the base 1. The cross-section of the bracket 3 is an inverted L shape. A purification box 4 is fixedly connected between the two brackets 3. The interior of the purification box 4 is a hollow structure. A connecting pipe 7 is arranged on one side of the calcination furnace body 2. The interior of the connecting pipe 7 is communicated with the interior of the calcination furnace body 2. The calcination furnace body 2 is connected to the purification box 4 through the connecting pipe 7. The interior of the connecting pipe 7 is communicated with the interior of the purification box 4. Through the connecting pipe 7, the chlorine gas inside the calcination furnace body 2 can be introduced into the interior of the purification box 4 for purification treatment. A first motor 6 is fixedly connected to the top of the purification box 4. The first motor 6 is an existing structure and will not be elaborated here in detail. The output end of the first motor 6 rotates through the top of the purification box 4 and extends into the interior of the purification box 4. A rotating rod 9 is fixedly connected to the output end of the first motor 6. A second motor 8 is fixedly connected to the right side of the purification box 4. The second motor 8 is an existing structure and will not be elaborated here in detail. The output end of the second motor 8 rotates through the purification box 4 and extends into the interior of the purification box 4. A fan 17 is fixedly connected to the output end of the second motor 8. An exhaust pipe 5 is fixedly connected to the left side of the purification box 4. The interior of the exhaust pipe 5 is communicated with the interior of the purification box 4. Two symmetrical U-shaped grooves 13 are opened on the inner wall of the purification box 4. The cross-section of the U-shaped groove 13 is a U shape. A filtering and purifying device is arranged inside the U-shaped groove 13.

[0023] Furthermore, a filter frame 15 is arranged inside the purification box 4. A filter net is arranged inside the filter frame 15. Through the filter net, impurities in the chlorine gas can be filtered. One side of the filter frame 15 is fixedly connected to the outer surface of the purification box 4 through bolts, which is convenient for staff to replace and repair the filter frame 15.

[0024] Furthermore, two symmetrical collecting grooves 19 are opened on the top of the filter frame 15. Mesh holes are opened on the side walls of the two collecting grooves 19. The collecting grooves 19 can centrally collect and process impurities. Through the mesh holes, the collecting grooves 19 can ensure the normal flow of chlorine gas while collecting impurities.

[0025] Furthermore, an activated carbon plate 20 is arranged inside the filter frame 15. The activated carbon plate 20 is located below the filter net. Through the adsorption effect of the microporous structure in the activated carbon plate 20 on the residual chlorine molecules in the chlorine gas, the chlorine gas can be purified to remove the toxic components contained in the chlorine gas. The purified chlorine gas is safely discharged through the exhaust pipe 5. To a certain extent, the purified chlorine gas can reduce the situation that staff's health is affected by inhaling toxic chlorine gas and the environmental pollution.

[0026] Further, the filtering and purifying device includes a U-shaped power frame 12, which is slidably connected to the inside of the U-shaped groove 13. The cross-section of the U-shaped power frame 12 is U-shaped. A power groove 18 is formed at the top of the U-shaped power frame 12. The bottom of the rotating rod 9 is fixedly connected to a transmission rod 10. One side of the bottom of the transmission rod 10 away from the rotating rod 9 is fixedly connected to a power column 11. By rotating the rotating rod 9, the rotating rod 9 drives the transmission rod 10 to perform centripetal rotation. The power column 11 is movably connected to the inside of the power groove 18. The power column 11 can rotate and move inside the power groove 18. A cleaning plate 14 is fixedly connected to the inside of the U-shaped power frame 12. The cleaning plate 14 is slidably connected to the inside of the U-shaped groove 13. A brush is provided at the bottom of the cleaning plate 14.

[0027] The staff starts the first motor 6 through the control device. The output end of the first motor 6 drives the rotating rod 9 to rotate. The rotating rod 9 drives the transmission rod 10 to perform centripetal rotation. The power column 11 drives the power column 11 to perform centripetal motion as well. At the same time, the power column 11 slides inside the power groove 18 and makes the U-shaped power frame 12 perform reciprocating motion. The U-shaped power frame 12 drives the cleaning plate to move. The impurities on the filter net can be cleaned in time through the brush. To a certain extent, when chlorine passes through the filter net, the impurities in the chlorine adhere to the filter net and cause a large amount of accumulation, blocking the filter net holes, and then resulting in a decrease in the ventilation volume and the situation that chlorine accumulates inside the purification box 4 and cannot be discharged. At the same time, the collection groove 19 provided at the top of the filter frame 15 can centrally collect and process the cleaned impurities, reducing the number of times the staff frequently disassembles the filter frame 15 for cleaning, and reducing the labor intensity of the staff to a certain extent.

[0028] Further, a converging frame 16 is fixedly connected to the lower surface inside the purification box 4. The inside of the converging frame 16 is a hollow structure. The inside of the exhaust pipe 5 is communicated with the inside of the converging frame 16. The inner wall of the converging frame 16 is an inclined surface. By rotating the fan 17, the chlorine inside the purification box 4 can be accelerated to flow, reducing to a certain extent the situation that a large amount of chlorine gathers inside the purification box 4 and is discharged out slowly. At the same time, the chlorine is driven by the fan 17 and quickly concentrated through the inclined surface inside the converging frame 16 and quickly discharged from the exhaust pipe 5.

[0029] Working principle: For a device for preparing magnesium oxide of this type, first, the burner inside the calciner body 1 is used to perform high-temperature calcination on the magnesium chloride solution to extract magnesium oxide. During the calcination, toxic chlorine gas is generated inside the calciner body 1. The staff controls the external control device to introduce the chlorine gas into the purification box 4 through the connecting pipe 7, and starts the first motor 6 through the external power supply. The output end of the first motor 6 drives the rotating rod 9 to rotate. The rotating rod 9 drives the transmission rod 10 to perform circular motion rotation. The power column 11 also makes a centripetal motion driven by the power column 11. At the same time, since the power column 11 is arranged on the side far from the rotating rod 9, the power column 11 slides inside the power groove 18 and makes the U-shaped power frame 12 perform reciprocating motion. The U-shaped power frame 12 drives the cleaning plate to move, and the impurities on the filter screen can be cleaned in time through the brush. The collected impurities can be centrally collected and processed through the collection tank 19 arranged at the top of the filter frame 15, reducing the number of times the staff frequently disassembles the filter frame 15 for cleaning and reducing the labor intensity of the staff to a certain extent. After the chlorine gas filtered from impurities undergoes a chemical reaction with the activated carbon plate 20 for purification, the staff controls the external device to start the second motor 8. The output end of the second motor 8 drives the fan 17 to rotate. By the rotation of the fan 17, the chlorine gas inside the purification box 4 can be accelerated to flow, reducing the situation that a large amount of chlorine gas gathers inside the purification box 4 and is discharged slowly to a certain extent. At the same time, the chlorine gas is driven by the fan 17 and quickly concentrates and is discharged from the exhaust pipe 5 through the inclined plane inside the gathering frame 16.
