They are essential basic materials to ensure the production and operation of the above industries and the technological development. They play an irreplaceable and important role in the development of high-temperature industrial production. In the production process of refractory materials, it is necessary to dry the powdered raw materials.

[0003] For example, the patent document with the announcement number CN217929598U discloses a drying device for refractory material production, which can lift up part of the refractory material through the rotation of the scraper, and then fall down under the action of gravity, so as to lift the refractory material and increase the contact area with the air, thereby improving the drying speed. When the above drying device is used, a certain amount of refractory material is poured into the cylinder, and the refractory material is taken out after drying, and then new refractory material is put in. In this way, continuous drying cannot be carried out, and the discharge is inconvenient, resulting in low overall processing efficiency. Utility Model Content

The plane where the material stripping plates 301 are located has an angle with the plane where the axis of the drying cylinder 3 is located, that is, the material stripping plates 301 are not parallel to the axis of the drying cylinder 3. When the drying cylinder 3 rotates, the material stripping plates 301 strip the refractory materials so as to slowly transport the refractory materials to the discharge end, and the material stripping plates 301 can lift the refractory materials so that the refractory materials can be more fully in contact with the hot air, thereby ensuring the drying effect.

[0028] The feed end of the drying cylinder 3 is rotatably connected to a first fixed plate 4 for feeding and air intake. The first fixed plate 4 is connected to the top of the base 1 by screws. The drying cylinder 3 can rotate relative to the first fixed plate 4. The top of the first fixed plate 4 is connected to a feed hopper 401 by screws. A feed channel 402 connected to the feed hopper 401 is provided inside the first fixed plate 4. A plurality of air inlet holes 403 are provided on the first fixed plate 4. Refractory materials enter the drying cylinder 3 through the feed hopper 401 and the feed channel 402. The air blowing mechanism 5 blows hot air into the drying cylinder 3 through the air inlet holes 403 to dry the refractory materials.

[0029] The blower mechanism 5 is arranged on a side of the first fixed plate 4 away from the drying cylinder 3, and the blower mechanism 5 includes a blower 501, an air inlet pipe 502, and an air hood 503. The blower 501 is connected to the top of the base 1 by screws, one end of the air inlet pipe 502 is connected to the air outlet of the blower 501, and the other end of the air inlet pipe 502 is welded to the air hood 503. The air hood 503 is connected to the side of the first fixed plate 4 away from the drying cylinder 3 by screws.

[0030] The discharge end of the drying cylinder 3 is rotatably connected to a second fixed plate 6 for discharging materials and exhausting air. The second fixed plate 6 is fixedly connected to the support seat 2 via a fixed rod 201. The drying cylinder 3 can rotate relative to the second fixed plate 6. A discharge pipe 601 is welded to the bottom of the second fixed plate 6. An electric-controlled valve is provided on the discharge pipe 601. An air outlet is provided at the top of the second fixed plate 6.

[0031] An exhaust mechanism 7 is provided on the top of the base 1, and the exhaust mechanism 7 includes an exhaust fan 701, an exhaust pipe 702, and a filter box 703.

One end of the exhaust pipe 702 is connected to the air inlet of the exhaust fan 701, and the other end of the exhaust pipe 702 is connected to the air outlet on the top of the second fixed plate 6. The exhaust fan 701 will extract the hot air and dust in the drying cylinder 3 through the exhaust pipe 702, so that the hot air is always in a flowing state to ensure the drying effect. The filter box 703 filters the dust, and the air outlet of the filter box 703 is located on the rear side to prevent the staff from being scalded when loading on the front side.

[0032] A striking mechanism 8 for vibrating the drying cylinder 3 is provided at the top of the base 1. The striking mechanism 8 includes a shell 802 fitted with the drying cylinder 3. A support rod 801 is connected to the bottom of the shell 802 by screws. The support rod 801 is connected to the top of the base 1 by screws to support the shell 802. A rotating shaft 803 is rotatably connected in the shell 802. A plurality of toggle rods 804 distributed in a spiral shape are fixedly connected to the rotating shaft 803. A plurality of steel balls to be toggled by the toggle rods 804 are placed in the shell 802. One end of the rotating shaft 803 extends out of the shell 802 and is fixedly connected to a driven gear 805. The driven gear 805 is meshed with the ring gear 302. When the drying cylinder 3 rotates, the driven gear 805 and the rotating shaft 803 are driven to rotate through the ring gear 302, so that the toggle rod 804 continuously lifts the steel balls, and then the steel balls fall and hit the outer wall of the drying cylinder 3, causing the wall of the drying cylinder 3 to vibrate and shake off the refractory material on the inner wall of the drying cylinder 3.

[0033] One end of the toggle rod 804 is bent into a spoon shape to facilitate lifting the steel ball. A guide groove 8021 corresponding to the toggle rod 804 is provided on the inner wall of the shell 802. The bent end of the toggle rod 804 is located in the guide groove 8021, so that the steel ball is lifted up by the toggle rod 804 along the guide groove 8021. A groove 8041 is provided on the toggle rod 804. When the bent end of the toggle rod 804 is away from the drying cylinder 3, as the bent end of the toggle rod 804 is lifted, the steel ball slides toward the direction of the drying cylinder 3 under the guidance of the groove 8041, thereby hitting the drying cylinder 3. The toggle rod 804 is distributed in a spiral shape on the rotating shaft 803, so that the steel ball hits different positions of the drying cylinder 3 in sequence to prevent the drying cylinder 3 from resonating.

[0034] Working principle: When in use, pour the refractory material into the feed hopper 401, the refractory material enters the drying cylinder 3 through the feed channel 402, the motor 902 drives the active gear 903 to rotate, the active gear 903 drives the ring gear 302 to rotate, the ring gear 302 drives the drying cylinder 3 to rotate, the drying cylinder 3 drives the material stripping plate 301 to rotate, the material stripping plate 301 makes the refractory material gradually move toward the second fixed plate 6, the blower 501 blows air, the electric heating wire in the air inlet pipe 502 is energized, the hot air enters the wind hood 503 and then enters the drying cylinder 3 through the air inlet hole 403, so as to dry the refractory material, the material stripping plate 301 lifts the refractory material, so that the refractory material is repeatedly lifted and dropped in the drying cylinder 3, so that the refractory material is in contact with the hot air more evenly and fully, thereby ensuring the drying effect, and the exhaust fan 701 exhausts air at the same time The hot air and dust in the drying cylinder 3 are sucked into the filter box 703 through the exhaust pipe 702. The filter box 703 filters the dust to reduce environmental pollution. During the rotation of the drying cylinder 3, the ring gear 302 drives the driven gear 805 to rotate, and the driven gear 805 drives the rotating shaft 803 to rotate. The rotating shaft 803 drives the toggle rod 804 to rotate. The bent end of the toggle rod 804 lifts the steel ball. When the steel ball rises to a certain height, it slides down along the groove 8041, thereby hitting the outer wall of the drying cylinder 3. Multiple toggle rods 804 make multiple steel balls hit different positions of the drying cylinder 3 in turn, causing the drying cylinder 3 to vibrate, thereby shaking off the refractory material adhered to the inner wall of the drying cylinder 3. As the drying cylinder 3 rotates, the dried refractory material moves to the second fixed plate 6, and the refractory material is discharged from the discharge pipe 601.
