Description

Technical Field

[0001] This utility model relates to the field of combustion furnace technology, and more specifically, to an environmentally friendly production combustion furnace for phosphorus pentoxide. Background Technology

[0002] Phosphorus pentoxide is an inorganic compound, a white powder, insoluble in acetone and ammonia, but soluble in sulfuric acid. It is mainly used as a desiccant for gases and liquids, a dehydrating agent in organic synthesis, an antistatic agent for polyester resins, and a refining agent for pharmaceuticals and sugars. It is also a precursor for producing high-purity phosphoric acid, phosphates, phosphides, and phosphate esters. It can be used in the manufacture of phosphorus pentoxide sols and H-type aerosols, and in the production of optical glass, ultraviolet-transmitting glass, heat-insulating glass, microcrystalline glass, and opaque glass to improve the dispersion coefficient and ultraviolet transmittance of glass. Currently, the industrial preparation of phosphorus pentoxide generally employs an oxidative combustion method: using yellow phosphorus as raw material, the yellow phosphorus is heated and melted, then added to a combustion furnace. Dry air is introduced into the furnace to react with the yellow phosphorus and burn, generating phosphorus pentoxide flue gas. The phosphorus pentoxide flue gas is then cooled and settled to produce the finished phosphorus pentoxide product. The combustion furnace is a key piece of equipment in the phosphorus pentoxide production process.

[0003] Typically, an exhaust gas filter is added to the exhaust port of the combustion furnace to filter the exhaust gas, but there are still shortcomings. The exhaust gas filter is prone to clogging, and if the clogging is severe, it will affect the exhaust gas discharge and filtration. Therefore, we provide an environmentally friendly phosphorus pentoxide production combustion furnace. Utility Model Content

[0021] Please see Figures 1 to 4 An environmentally friendly phosphorus pentoxide production combustion furnace includes a furnace body 1 and a treatment box 2. A filter screen 3 is fixedly connected inside the treatment box 2. A movable plate 4 is slidably connected inside the treatment box 2. A groove 5 is formed inside the movable plate 4, and a slider 6 is slidably connected inside the groove 5. A rotating plate 7 is rotatably connected to the outside of the slider 6. Under the action of the groove 5 and the slider 6, when the rotating plate 7 rotates, the movable plate 4 can move up and down inside the treatment box 2. A fixed plate 8 is fixedly connected to the outside of the movable plate 4. A cleaning roller 9 is rotatably connected and works in conjunction with a filter screen 3. A ring 10 is fitted around the outside of the cleaning roller 9 and is slidably connected to the cleaning roller 9. A connecting rod 11 is fixedly connected to the outside of the ring 10 and is fixedly connected to the slider 6. When the movable plate 4 moves up and down, the slider 6 moves left and right in the groove 5, so that the slider 6 can drive the ring 10 to move left and right outside the cleaning roller 9 through the connecting rod 11. This allows the ring 10 to move the bristles on the cleaning roller 9 and prevent impurities from adhering to the cleaning roller 9.

[0022] Furthermore, the outer wall of the slider 6 is in contact with the inner wall of the groove 5, and the slider 6 and the groove 5 are tightly fitted, so that when the rotating plate 7 rotates, it can drive the movable plate 4 to move up and down through the groove 5 and the slider 6. The movable plate 4 then drives the cleaning roller 9 to move up and down through the fixed plate 8, thereby cleaning the filter screen 3.

[0023] Furthermore, a motor 12 is fixedly connected to the outside of the processing box 2. The output shaft of the motor 12 passes vertically through the processing box 2 and extends into the interior of the processing box 2. The output shaft of the motor 12 is rotatably connected to the processing box 2. The rotating plate 7 is fixedly connected to the output end of the motor 12. The motor 12 drives the rotating plate 7 to rotate. The rotating plate 7 drives the movable plate 4 to move up and down through the slider 6 and the slide groove 5.

[0024] Furthermore, the movable plate 4 has a guide groove 13 inside, and a guide rod 14 is slidably connected inside the guide groove 13. The guide rod 14 is fixedly connected to the processing box 2. Since the movable plate 4 needs to move up and down, the guide groove 13 and the guide rod 14 guide and limit the movable plate 4, making the movable plate 4 move up and down more smoothly.

[0025] Furthermore, a gear 15 is fitted on the outside of the cleaning roller 9, and the gear 15 is fixedly connected to the cleaning roller 9. A rack 16 is fixedly connected inside the processing box 2, and the gear 15 and the rack 16 mesh with each other. Through the gear 15 and the rack 16, when the movable plate 4 drives the cleaning roller 9 to move up and down as a whole, the cleaning roller 9 itself will also rotate, thereby cleaning the filter screen 3 better.

[0026] Furthermore, an exhaust pipe 17 is fixedly connected to one side of the treatment box 2, and an intake pipe 18 is fixedly connected to the other side of the treatment box 2. The intake pipe 18 is fixedly connected to the combustion furnace body 1. The exhaust gas discharged from the combustion furnace body 1 enters the treatment box 2 through the intake pipe 18, and then is filtered by the filter screen 3 inside the treatment box 2. Finally, the filtered exhaust gas is discharged from the treatment box 2 through the exhaust pipe 17.

[0027] The steps of using this utility model are as follows: When using this phosphorus pentoxide environmentally friendly production combustion furnace, the exhaust gas of the main body 1 of the combustion furnace enters the treatment box 2 through the air inlet pipe 18. The exhaust gas is filtered through the filter screen 3 in the treatment box 2. The filtered exhaust gas is discharged from the treatment box 2 through the air outlet pipe 17. When it is necessary to clean the filter screen 3, the motor 12 is started to drive the rotating plate 7 to rotate. The rotating plate 7 drives the movable plate 4 to move up and down through the slider 6 and the slide groove 5. The movable plate 4 drives the cleaning roller 9 to clean the filter screen 3 up and down through the fixed plate 8. At the same time, the cleaning roller 9 is driven to rotate by the gear 15 and the rack 16 to improve the cleaning effect. Since the slider 6 moves back and forth in the slide groove 5, the slider 6 can drive the ring 10 through the connecting rod 11 to move the bristles on the cleaning roller 9 back and forth to prevent impurities from adhering to the bristles.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model.
