Specific Embodiments
[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments with reference to the accompanying drawings in the embodiments of the present utility model. The following embodiments are used to illustrate the present utility model.
[0021] As Figures 1 - 4As shown, the zinc oxide recovery device for blast furnace bag dust containing zinc materials includes a recovery box 10. The cavity of the recovery box 10 is in a hollow state. A reaction box 18 is fixedly installed in the cavity of the recovery box 10. Flow ports 33 are provided on the two side walls of the reaction box 18. A heating device for heating the zinc materials is arranged in the cavity of the reaction box 18. The heating device includes a heating box 19.
[0022] In the specific working process, the reaction box 18 is installed in the cavity of the recovery box 10, and a heating device is arranged on the reaction box 18. The materials in the cavity of the graphite crucible 21 are continuously heated by the heating device, so that the temperature in the cavity of the graphite crucible 21 reaches above 1300 degrees, thereby reducing the zinc in the materials to zinc vapor.
[0023] The heating box 19 is in a concave shape and is fixedly installed in the cavity of the reaction box 18. A semiconductor heating sheet 20 is embedded in the frame of the heating box 19. A graphite crucible 21 is movably installed in the cavity of the heating box 19. The cavity of the graphite crucible 21 is in a hollow state. A crucible cover 22 is arranged on the top wall of the graphite crucible 21, and a hook ring 23 is fixedly installed on the top wall of the crucible cover 22.
[0024] In the specific working process, the graphite crucible 21 arranged in the cavity of the heating box 19 is heated by the semiconductor heating sheet 20, and the crucible cover 22 seals the graphite crucible 21, which can accelerate the rapid increase in the temperature in the cavity of the graphite crucible 21 and accelerate the conversion of zinc in the materials into the required zinc vapor.
[0025] A lifting box 26 is fixedly installed on the top wall of the recovery box 10. The cavity of the lifting box 26 is in a hollow state. A lifting device for making the zinc vapor contact with air is arranged in the cavity of the lifting box 26. The lifting device includes a rotating rod 28.
[0026] In the specific working process, when the value on the thermometer 11 reaches the required temperature, the lifting device lifts the crucible cover 22 and the plugging block 32 upward, so that the zinc vapor enters the cavity of the reaction box 18 and contacts the air entering through the flow ports 33, and the zinc vapor forms zinc oxide.
[0027] The rotating rod 28 is movably installed in the cavity of the lifting box 26. A servo motor 29 is movably installed on one side of the rotating rod 28. The rotating rod 28 is connected to the output end of the servo motor 29. The other end of the servo motor 29 is fixedly installed on the inner wall of the lifting box 26. A first pulley 27 is fixedly installed on the outer wall of the rotating rod 28. A first lifting rope 25 is installed in the cavity of the first pulley 27. One end of the first lifting rope 25 is fixedly connected in the cavity of the first pulley 27. The other end of the first lifting rope 25 passes through the lifting box 26 and the recovery box 10 and extends into the cavity of the recovery box 10. The end of the first lifting rope 25 extending into the cavity of the recovery box 10 is fixedly installed with a lifting hook 24, and the position of the lifting hook 24 corresponds to the position of the hook ring 23.
[0028] The servo motor 29 drives the rotating rod 28 to rotate. The rotation of the rotating rod 28 drives the first pulley 27 and the second pulley 30 to rotate. The rotation of the first pulley 27 retracts and lifts the first lifting rope 25, and the upward movement of the first lifting rope 25 drives the corresponding crucible cover 22 to move upward.
[0029] On the outer wall of the rotating rod 28, two second pulleys 30 are fixedly installed. The two second pulleys 30 are in a parallel state. A second lifting rope 31 is installed in the cavities of the two second pulleys 30. The two second lifting ropes 31 both penetrate through the recovery box 10 and extend into the cavities of the corresponding circulation ports 33. At one end of the two second lifting ropes 31 extending into the cavities of the corresponding circulation ports 33, a blocking block 32 is fixedly installed. The position of the blocking block 32 corresponds to the position of the second lifting rope 31.
[0030] The rotation of the second pulley 30 drives the second lifting rope 31 to retract and lift. The upward retraction and lifting of the second lifting rope 31 drives the blocking block 32 to move upward. The upward movement of the blocking block 32 allows air to enter the cavity of the reaction box 18 through the circulation port 33 and react with the zinc vapor in the cavity of the reaction box 18.
[0031] On the front side wall of the recovery box 10, a thermometer 11 is fixedly installed. On the front side wall of the recovery box 10, a box door 16 is opened. On the front side wall of the box door 16, a second handle 17 is fixedly installed. The position of the reaction box 18 corresponds to the position of the box door 16. On the bottom wall of the reaction box 18, a blanking hole is opened, and the blanking holes are evenly distributed on the bottom wall of the reaction box 18.
[0032] During the specific working process, the thermometer 11 detects the temperature in the cavity of the reaction box 18 in real time. After the zinc vapor forms zinc oxide with air, crystals are formed as the temperature decreases. The zinc oxide crystals move out of the cavity of the reaction box 18 through the blanking holes on the bottom wall of the reaction box 18.
[0033] A collecting device for polymerizing zinc oxide is movably installed in the cavity of the recovery box 10. The collecting device includes a collecting box 12. The collecting box 12 is movably installed in the cavity of the recovery box 10. On the front side wall of the collecting box 12, a first handle 13 is fixedly installed. On the two side walls of the collecting box 12, sliding grooves 14 are opened. On the two inner side walls of the recovery box 10, sliding blocks 15 are fixedly installed. The position of the sliding grooves 14 corresponds to the position of the sliding blocks 15. The sliding blocks 15 are movably installed in the cavities of the sliding grooves 14.
[0034] During the specific working process, the collecting box 12 slides on the sliding blocks 15 through the sliding grooves 14, enabling the collecting box 12 to easily move in or out of the cavity of the recovery box 10. When the collecting box 12 has completed the collection of the zinc oxide crystals, the collecting box 12 is pulled out of the cavity of the recovery box 10, and the zinc oxide in the cavity of the collecting box 12 is collected manually.
