DETAILED DESCRIPTION OF THE EMBODIMENTS

[0032] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0033] Referring to Figure 1 - Figure 2 , an embodiment provided by the present utility model: a drying device for producing fused magnesia, including a processing box 1. A drying shell 2 is fixedly connected inside the processing box 1. A feed pipe 3 is fixedly connected to the right end of the upper surface of the drying shell 2. The left end of the drying shell 2 is provided with an open structure. An outlet is opened on the left side of the processing box 1. A sealing door is hinged at the outlet. When the sealing door is closed, the inside of the processing box 1 and the drying shell 2 can be sealed to avoid heat loss. A sealing sleeve is sleeved on the upper end of the feed pipe 3 to seal the upper end of the feed pipe 3. A stirrer 4 is arranged inside the drying shell 2. The stirrer 4 includes a motor and an auger. When the motor is started, the auger can be driven to rotate, and then the fused magnesia raw materials entering the inside of the drying shell 2 through the feed pipe 3 can be turned over. When the motor continuously drives the auger to rotate forward and backward, the raw materials can be driven to move back and forth left and right and turn over inside the drying shell 2, so as to uniformly and completely dry the raw materials. This is a simple prior art in this field and will not be elaborated here. An electric heater is fixedly connected to the bottom surface of the drying shell 2. When the electric heater is started, it can dry the fused magnesia raw materials located inside the drying shell 2.

[0034] Referring to Figure 3 - Figure 5, at the upper end surface of the right inner wall of the drying housing 2, an exhaust pipe 5 is fixedly connected. An air inlet 6 is opened at the bottom end of the exhaust pipe 5. The upward floating water vapor generated during the drying and processing inside the drying housing 2 can enter the exhaust pipe 5 through the air inlet 6. Oblique plates 7 are fixedly connected to both the front and rear ends of the air inlet 6. One end of the oblique plate 7 away from the air inlet 6 is fixedly connected to the inner wall of the drying housing 2. When the water vapor floats upward, it can completely enter the interior of the exhaust pipe 5 along the bottom inclined surface of the oblique plate 7, which can improve the dehumidification efficiency inside the drying housing 2 and prevent the excessive humidity inside the drying housing 2 from affecting the drying efficiency and effect during the drying process. A circulation pipe 8 is arranged outside the processing box 1. The right rear end of the circulation pipe 8 penetrates through the right surface of the processing box 1. The right rear end of the circulation pipe 8 is fixedly connected to the right end of the exhaust pipe 5. The left end of the exhaust pipe 5 penetrates through the processing box 1, and the left end of the exhaust pipe 5 is fixedly connected to the left rear end of the circulation pipe 8. The interiors of the exhaust pipe 5 and the circulation pipe 8 are interconnected to form a complete circulation loop. A circulation pump 9 is fixedly connected to the front end of the circulation pipe 8. When the circulation pump 9 is started, it will extract the water vapor floating at the upper end inside the drying housing 2 from the left end of the air inlet 6 and enter it into the circulation pipe 8 for circulation processing. A moisture-proof unit is arranged at the left rear end of the circulation pipe 8.

[0035] The moisture-proof unit includes a fixed housing 81, which is fixedly connected to the left rear end of the circulation pipe 8. Both the left and right ends of the fixed housing 81 are arranged in an open structure. The addition of the fixed housing 81 will not affect the integrity of the circulation loop. A slot 82 is opened on the inner bottom surface of the fixed housing 81, and a threaded groove 83 is opened on the upper inner wall surface of the fixed housing 81. A stud 84 is threadedly connected to the upper end inside the fixed housing 81 through the threaded groove 83. When the stud 84 is screwed into the threaded groove 83, it can seal the upper end of the fixed housing 81. A rotating rod 85 is fixedly connected to the bottom end of the stud 84, and the bottom end of the rotating rod 85 is inserted into the interior of the slot 82. The provided slot 82 can limit the bottom end of the rotating rod 85, so that the rotating rod 85 remains stable during use. A sponge ball 86 is rotatably connected to the outer side of the rotating rod 85. The sponge ball 86 can rotate around the rotating rod 85. A sponge rib 87 is fixedly connected to the outer side of the sponge ball 86. When the airflow blows the sponge rib 87, it can drive the sponge ball 86 to move synchronously. A guide plate 10 is fixedly connected to the left end surface of the rear inner wall of the exhaust pipe 5. The front end of the guide plate 10 is arranged in a structure inclined towards the left center inside the exhaust pipe 5.

[0036] When the circulating pump 9 starts to pump air and water vapor, the air flow can be guided by the guide plate 10 and then blown to the right front end of the sponge ball 86. At this time, the air flow will drive the sponge ball 86 to rotate by blowing the sponge convex strip 87 located at this position. The surface of the rotating sponge ball 86 will come into full contact with the extracted gas, improving the moisture-proof effect of the sponge ball 86. Furthermore, it can avoid the situation that the right end of the sponge ball 86 absorbs moisture faster than other parts because it is the first to come into contact with the gas, which may affect the service life and use effect of the sponge ball 86. When the sponge ball 86 is completely filled with moisture, the staff can turn the stud 84 to quickly disassemble and replace the sponge ball 86, which is easy to operate.

[0037] Refer to Figure 6 , on the upper surface of the right inner wall of the drying housing 2, a fixing plate 11 is fixedly connected. The fixing plate 11 is located at the upper right side of the exhaust pipe 5. At the upper end of the fixing plate 11, a telescopic rod 12 is fixedly connected. A spring 13 is sleeved outside the telescopic rod 12. At the upper end of the telescopic rod 12, a protective plate 14 is fixedly connected. The upper end of the spring 13 is fixedly connected to the bottom surface of the protective plate 14, and the bottom end of the spring 13 is fixedly connected to the upper surface of the fixing plate 11. The protective plate 14 is located directly below the feed pipe 3. When the protective plate 14 moves downward under impact, it can compress the spring 13, causing the spring 13 to generate elastic potential energy. Both the front and rear ends of the protective plate 14 are inclined downward, and a rubber plate 15 is fixedly connected to the upper end of the protective plate 14.

[0038] When the fused magnesia raw material is added into the drying housing 2 through the feed pipe 3, the provided protective plate 14 can protect the right end of the exhaust pipe 5, preventing the raw material from hitting the right end of the exhaust pipe 5 and causing damage to the exhaust pipe 5. And through the double buffering of the rubber plate 15 and the spring 13, the impact force on the protective plate 14 is buffered and offset, extending the service life of the protective plate 14. When the raw material hits the protective plate 14, it can slide down along the inclined surfaces at the front and rear ends of the protective plate 14, preventing the raw material from not being completely dried inside the drying housing 2.

[0039] Working principle: When the fused magnesia raw materials are added into the drying housing 2 through the feeding pipe 3 for drying treatment, the water vapor generated during the drying process will float upward and enter the exhaust pipe 5 through the air inlet 6 along the inclined surface of the inclined plate 7. Subsequently, the circulation pump 9 can be started to extract the water-containing air to make it circulate. When the air flow reaches the sponge ball 86 through the diversion of the guide plate 10 during the flowing process, it will drive the sponge ball 86 to rotate, so that the surface of the sponge ball 86 can completely absorb the moisture, reduce the humidity in the drying housing 2, avoid the influence of excessive humidity on the drying efficiency and effect. At the same time, the hot air can return to the drying housing 2 to reduce the loss of heat. When the surface of the sponge ball 86 is full of moisture, the stud 84 can be turned to disassemble and replace the sponge ball 86.

[0040] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
