Description

Technical Field

[0001] The invention relates to the technical field of antimony trioxide production equipment, in particular to a calcining furnace for antimony trioxide production. Background Art

[0002] The calcining furnace for antimony trioxide production is a furnace body used to calcine antimony trioxide. Antimony trioxide is an inorganic compound, a natural product called antimony flower, commonly known as antimony white. There are two preparation methods: dry method and wet method. The dry method includes metal antimony method and stibnite method. In the metal antimony method, the material needs to be placed in a calcining furnace for high-temperature heating after a preliminary chemical reaction. During the combustion, a protective film is formed on the surface of antimony trioxide to isolate the air. Antimony trioxide is a toxic substance and is easily gasified in a high-temperature environment.

[0003] The patent number CN218238362U discloses a calcining furnace for producing antimony trioxide. By setting a driving motor, a rotating column and a crushing knife, during the calcining process, the driving motor is controlled to drive the rotating column to rotate, and the rotating column rotates the crushing knife to continuously crush the material in the calcining furnace. At the same time, the oxygen supply box continuously blows oxygen, so that the material is fully in contact with oxygen, thereby improving the production efficiency of the device. However, when the device is actually used, the following defects still exist:

[0004] The above patent mainly crushes the material by a crushing knife and cooperates with oxygen contact to improve the calcination efficiency. However, after the material is crushed, the material placed inside the furnace body is extremely scattered and needs to wait for the furnace to cool down, which makes it extremely difficult to remove the material. At the same time, when the material is crushed, the contact surface between oxygen and the material is not comprehensive, which makes it difficult to ensure uniform calcination of the material. During the processing in the furnace, smoke is easily generated. The direct discharge of this smoke will greatly increase the heat energy loss in the furnace, making it difficult to keep the inside of the furnace warm. At the same time, the discharged smoke not only carries heat, but also contains toxic substances. Direct discharge affects the working environment outside the device and reduces the environmental friendliness of the calcining furnace. Summary of the invention

The oxygen supply device 4 introduces oxygen into the gas guide cylinder 53 through the connecting pipe and discharges it evenly from the multiple exhaust ports 52, so as to allow oxygen to be introduced into the gas guide cylinder 53, thereby causing the oxygen to be discharged from the multiple exhaust ports 52 evenly and cover the material evenly for a reaction.

[0035] As a preferred solution of this embodiment: a through groove is opened at one end of the front side of the furnace body 3, and a heat-resistant sealing pad is provided at the edge of one end of the back side of the sealing door 88. The sealing door 88 and the through groove are sealed to improve the sealing of the structure and the heat resistance of the sealing door.

[0036] As a preferred solution of this embodiment: limiting grooves are provided on both sides of one end of the back side of the sealing door 88, and limiting blocks interconnected with the discharge chute 81 are provided on the inner side of the limiting grooves.

[0037] As a preferred solution of this embodiment: a drain valve is provided on one side of the water tank 25, and the drain valve extends out of the outside of the machine 1, and an isolation net is provided on one side of the inner side of the water tank 25, which can automatically filter impurities in the water liquid, so that the water liquid used in the water circulation remains clean and purifies the flue gas.

[0039] As a preferred solution of this embodiment: an activated carbon mesh layer is provided on the inner side of the exhaust pipe 29, and one side of the exhaust pipe 29 extends out of the machine 1 and is provided with a dustproof net, so as to improve the purification and adsorption effect of the flue gas and increase the exhaust efficiency of the flue gas purification.

[0040] Embodiment 1, as Figure 1-3 As shown, after the material reacts at high temperature in the calcining furnace, the engagement and positioning of the two sets of positioning members 89 can be cancelled, and then the sealing door 88 drives the discharge chute 81 to be withdrawn and separated from the furnace body 3, so as to quickly cool the calcining furnace and the material. After the cooling is completed, an antimony trioxide collection box can be placed on the inner side of the L-shaped bracket 7, and then the discharge valve 84 can be opened to collect the antimony trioxide formed by the reaction, thereby completing the production operation of antimony trioxide, increasing the operability and convenience of taking materials after antimony trioxide processing, and improving the unified collection rate of materials.

[0041] Embodiment 2, as Figure 1-4 As shown, when a high-temperature reaction is carried out in the calcining furnace, the smoke calcined in the furnace body 3 can be actively absorbed through the smoke exhaust pipe 21 and introduced into the insulation pipe 23. During this period, external oxygen is sucked in through the air intake pipe 22 and flows under the spiral structure of the spiral pipe 24. During this period, the smoke entering the insulation pipe 23 is preheated to heat the spiral pipe 24, so that the oxygen is heated and flows into the furnace body 3 from the waste heat conduit 210 to supply hot gas, thereby maintaining the temperature in the furnace body 3 under the structure of waste heat utilization to avoid rapid heat loss. After the flue gas enters the smoke purification chamber, the water in the water tank 25 is pumped out by starting the water pump 27 and sprayed evenly through the watering pipe 28. At the same time, under the filtration of the filter 26, the water is dispersed and covered in the flowing flue gas for purification, so that the flue gas is purified under the coverage of the water and the multiple filter structures of the filter 26, so that the impurities in the flue gas are separated from the gas, and the gas is discharged after purification, while the impurities fall into the water tank 25 together, so that they can be discharged after the water is recycled for many times, thereby increasing the waste heat recovery and smoke purification effect of the calciner flue gas treatment.

[0042] Working Principle: The antimony trioxide is produced in a calcining furnace;

[0043] When using the calcining furnace to process and produce antimony trioxide, first, the sealing door 88 drives the discharge trough 81 to be pulled out and separated from the furnace body 3 under the sliding cooperation of the two sets of guide grooves 87 and the guide blocks, so that the discharge trough 81 is exposed to the outside as a whole. At this time, the material can be placed in it and pushed into the furnace body 3 again for sealing. At the same time, under the engagement and positioning of the two sets of positioning members 89, the sealing door 88 is forced to fit tightly with the furnace body 3 for sealing. At this time, the heating device 83 and the heating structure of the heating tube 82 can be started to heat the material in the discharge trough 81 to a high temperature, so that the antimony trioxide is vaporized when heated. During this period, the servo motor 810 can be started to drive the screw rod 85 to rotate, so that the screw rod 85 drives the internal threaded tube 8 6 and the discharge trough 81 are raised and lowered as a whole at one end of the back of the sealing door 88, so that the inner side of the discharge trough 81 is raised to the pulverizing structure of the pulverizing blade 51. At this time, the start of the driver 56 drives the second gear 57 to mesh with the first gear 55 structure, so that the first gear 55 drives the pulverizing blade 51 to rotate to pulverize and stir the material. During this period, oxygen is supplied to the air guide cylinder 53 through the oxygen supply device 4, so that oxygen is introduced into the rotating air guide cylinder 53 and sent to multiple groups of exhaust ports 52 to spray outward, so that the oxygen can evenly contact the surface of the material with the pulverizing structure, so that the reaction of the material in a high temperature environment is more uniform and efficient, thereby accelerating the progress and quality of antimony trioxide production and improving production efficiency.

[0044] Finally, it should be noted that the above content is only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Simple modifications or equivalent substitutions of the technical solution of the present invention by ordinary technicians in this field do not deviate from the essence and scope of the technical solution of the present invention.
