Description

Technical Field

[0001] This utility model relates to the field of alumina ceramic processing technology, specifically a rotary alumina ceramic dryer. Background Technology

[0002] Alumina ceramics are ceramic materials with alumina (Al2O3) as the main component. They have excellent properties such as high hardness, high strength, high temperature resistance, corrosion resistance, and good insulation. Due to their excellent physical and chemical properties, alumina ceramics are widely used in many fields.

[0003] Alumina ceramics are mostly produced by pressing powdered raw materials into shape and then sintering them. To ensure the quality of alumina ceramics, the dryness of the powdered raw materials must be guaranteed, which requires drying treatment. Existing dryers have poor drying efficiency, and because the powdered raw materials are piled up, it is difficult to dry them evenly, resulting in some powdered raw materials not being completely dried, which affects the quality of alumina ceramics. Therefore, further improvements are needed. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides the following technical solution: a rotary alumina ceramic dryer, comprising a mounting base, a drying tank fixedly mounted on the top of the mounting base, a rotating tank rotatably connected inside the drying tank, a feed pipe connected to the left side of the rotating tank, a discharge pipe connected to the right side of the rotating tank, a rotating shaft rotatably connected to the center of the drying tank, and the rotating tank fixedly mounted on the outside of the rotating shaft, a reduction motor fixedly mounted on the right side of the mounting base, and several heating plates fixedly mounted in an array on the inner wall of the drying tank.

[0005] As an optimization, a connector is provided at the connection point between the feed pipe, the discharge pipe, and the rotating tank, and a solenoid valve is installed inside the connector.

[0006] As an optimization, ring rails are fixedly installed on both outer sides of the rotating tank, and supports are fixedly installed in an array on the inner wall of the drying tank corresponding to the ring rails. The supports are rotatably connected to the wheels, and the ring rails are rotatably connected between the wheels. The rotating tank can be supported and positioned by the supports and the wheels.

[0007] As an optimization, four sets of supports are installed around the ring rail array, and the rotating wheel rolls against the outer side of the ring rail corresponding to the support.

[0008] As an optimization, a heating tube is installed inside the wall of the rotating tank, and the heating tube is in the shape of a spiral spring. The raw materials in the rotating tank are further dried by heating through the heating tube, thereby improving the drying efficiency.

[0009] As an optimization, the inner wall of the rotating tank is equipped with stirring blades, and the stirring blades are in the shape of spiral blades. The stirring blades can disperse the powder raw materials inside the rotating tank when it rotates.

[0010] As an optimization, a hot air blower is provided on the right side of the drying tank. An air inlet pipe is inserted into the air outlet of the hot air blower and is inserted into the inside of the rotating shaft. Several sets of exhaust components are installed at equal intervals on the outside of the rotating shaft. When the hot air blower is started, hot air will be discharged along the air inlet pipe and then discharged into the rotating tank through the exhaust components.

[0011] As an optimization, the exhaust component includes a fixing ring fixedly mounted on the outside of the rotating shaft, and nozzles are arrayed on the outer side of the fixing ring.

[0012] The beneficial effects of this utility model are:

[0013] This rotary alumina ceramic dryer uses a heating plate to heat and dry the powder raw materials inside evenly, and then uses a heating tube to further heat and dry the raw materials in the rotating tank. When the rotating tank rotates, the stirring blades can disperse the powder raw materials inside, thereby avoiding local accumulation of raw materials that are not completely dried and improving drying efficiency.

[0014] This rotary alumina ceramic dryer, when the hot air blower is started, will discharge hot air along the air inlet pipe, so that the hot air will be delivered to the nozzles and then sprayed outward. The nozzles arranged around the rotating shaft can evenly dry all spaces in the rotating tank, thus enabling the powder raw materials in the rotating tank to be dried in all directions. The dried material is then discharged into the rotating tank through the exhaust device, and the hot air further accelerates the drying efficiency. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-2 A rotary alumina ceramic dryer includes a mounting base 1, a drying tank 2 fixedly mounted on the top of the mounting base 1, a rotating tank 3 rotatably connected inside the drying tank 2, a feed pipe 4 connected to the left side of the rotating tank 3, a discharge pipe 5 connected to the right side of the rotating tank 3, a rotating shaft 6 rotatably connected to the center of the drying tank 2, and the rotating tank 3 fixedly mounted on the outside of the rotating shaft 6. A geared motor 7 is fixedly mounted on one side of the right end of the mounting base 1, and several heating plates 8 are fixedly mounted in an array on the inner wall of the drying tank 2.

[0023] Please see Figure 2-3 A connector 9 is provided at the connection between the feed pipe 4, the discharge pipe 5, and the rotating tank 3. A solenoid valve is installed in the connector 9. By inserting the feed pipe 4 into the connector 9, the solenoid valve is opened, and the powder raw material can be conveyed into the rotating tank 3 along the feed pipe 4. After that, the feed pipe 4 is pulled out and the solenoid valve is closed, and the rotating tank 3 is driven to rotate by the rotating shaft 6 to uniformly dry the powder raw material inside. After drying, the discharge pipe 5 is inserted into the connector 9 on the right side to pull out the dried powder raw material.

[0024] Please see Figure 2-3 Both ends of the rotating tank 3 are fixedly installed with ring rails 10. The inner wall of the drying tank 2 is fixedly installed with supports 11 in an array corresponding to the ring rails 10. Four sets of supports 11 are installed around the ring rails 10. The inside of the supports 11 is rotatably connected with a rotating wheel 12, and the ring rails 10 are rotatably connected between the rotating wheels 12. The rotating wheels 12 roll against the outside of the ring rails 10 corresponding to the supports 11. The rotating tank 3 can be supported and positioned by the supports 11 and the rotating wheels 12, so that the rotating tank 3 can rotate inside the drying tank 2.

[0025] Please see Figure 4 The rotating tank 3 is equipped with a heating tube 13 inside its wall. The heating tube 13 is in the shape of a spiral spring. The heating tube 13 heats the raw materials inside the rotating tank 3 to further dry them and improve the drying efficiency. The inner wall of the rotating tank 3 is equipped with a stirring blade 14. The stirring blade 14 is in the shape of a spiral blade. The stirring blade 14 can disperse the powder raw materials inside the rotating tank 3 when it rotates, so as to avoid the accumulation of local raw materials that are not completely dried and improve the drying efficiency.

[0026] Please see Figure 4 A hot air blower 15 is installed on the right side of the drying tank 2. An air inlet pipe 16 is inserted into the air outlet of the hot air blower 15 and the air inlet pipe 16 is inserted into the inside of the rotating shaft 6. Several sets of exhaust components are installed at equal intervals on the outside of the rotating shaft 6. When the hot air blower 15 is started, hot air will be discharged along the air inlet pipe 16 and then discharged into the rotating tank 3 through the exhaust components. The drying efficiency is further accelerated by the hot air.

[0027] Please see Figure 4 The exhaust system includes a fixing ring 17 fixedly installed on the outside of the rotating shaft 6. The outer side of the fixing ring 17 is equipped with an array of nozzles 18. Hot air is delivered through the air inlet pipe 16 and sprayed evenly along the nozzles 18, thereby drying the powder raw materials in the rotating tank 3 in all directions.

[0028] In use, first insert the feed pipe 4 into the connector 9, then open the solenoid valve to feed the powder raw material into the rotating tank 3 along the feed pipe 4. Then pull out the feed pipe 4 and close the solenoid valve. Then the rotating shaft 6 will be driven to rotate by the reduction motor 7, which will cause the rotating tank 3 to rotate in the drying tank 2. At this time, the powder raw material inside can be heated and dried evenly by the heating plate 8. Then the raw material in the rotating tank 3 will be further heated and dried by the heating tube 13. When the rotating tank 3 rotates, the stirring plate 14 can disperse the powder raw material inside the rotating tank 3.

[0029] At the same time, by starting the hot air blower 15, hot air will be discharged along the air inlet pipe 16, so the hot air will be delivered to the nozzle 18 and then sprayed outward. The nozzles 18 arranged in an array around the rotating shaft 6 can evenly dry each space in the rotating tank 3, thereby drying the powder raw materials in the rotating tank 3 in all directions before being discharged into the rotating tank 3 through the exhaust device.

[0030] After drying, the discharge pipe 5 is inserted into the connector 9 on the right side to extract the dried powder raw material.

[0031] In summary, this rotary alumina ceramic dryer can heat and dry the powder raw materials inside evenly through the heating plate 8, and further heat and dry the raw materials in the rotating tank 3 through the heating tube 13. When the rotating tank 3 rotates, the stirring plate 14 can disperse the powder raw materials inside the rotating tank 3, thereby avoiding the accumulation of local raw materials that are not completely dried and improving the drying efficiency.

[0032] By starting the hot air blower 15, hot air will be discharged along the air inlet pipe 16, so the hot air will be delivered to the nozzle 18 and then sprayed outward. The nozzles 18 arranged in an array around the rotating shaft 6 can evenly dry each space in the rotating tank 3, thereby drying the powder raw materials in the rotating tank 3 in all directions. The dried materials are then discharged into the rotating tank 3 through the exhaust device, and the drying efficiency is further accelerated by the hot air.
