Description

Technical Field

[0001] This utility model belongs to the technical field of red phosphorus production equipment, and in particular relates to a phosphorus scraping device for a red phosphorus conversion pot. Background Technology

[0002] Currently, the production process for red phosphorus is as follows: yellow phosphorus → melting in a pot → high-temperature conversion → ball milling → alkaline boiling → washing → centrifugal dehydration → vacuum drying → packaging and warehousing. The conversion principle is as follows: the packaged yellow phosphorus is heated to a temperature of approximately 295℃-300℃ for an extended period in the absence of air, which converts it into red phosphorus. After grinding and alkaline boiling, it is then washed, dehydrated, and dried to obtain the finished red phosphorus. The entire red phosphorus production process consists of conversion, ball milling, alkaline boiling, washing, dehydration, drying, and packaging.

[0003] Existing red phosphorus conversion pot scraping devices generally include a sealed conversion pot. For example, patent document with publication number "CN220454259U" discloses a conversion furnace, including a base; a furnace body located on top of the base; a furnace cover detachably installed on top of the furnace body and sealing the furnace body; an exchange pipe installed on top of the furnace cover; a gas outlet pipe installed on top of the furnace cover; a lifting lug fixed to the top of the furnace cover; and a heating mechanism located on top of the base and used to heat the furnace body. The heating mechanism includes a placement seat fixed to the top of the base, the top of which has an installation groove for mounting a device. The furnace is equipped with heating wire one, and a heat-conducting plate is installed in the mounting groove. Using this patented technology, when heating wire one and heating wire two are used to heat the furnace body, they are in close contact with the furnace body, which improves the uniformity of heating of the furnace body. However, in order to make the material in the conversion pot evenly heated, it is common to set up a scraping mechanism in the conversion pot to make the material evenly mixed during heating. However, existing conversion pots are generally round. During the existing red phosphorus generation process, it often adheres to the inner wall surface of the conversion pot. The shape of the existing scraping mechanism is often different from the shape of the inner wall surface of the conversion pot, making it impossible for the scraping mechanism to completely scrape off the material adhering to the inner wall surface of the conversion pot, resulting in material waste. Summary of the Invention

[0004] To solve the above-mentioned technical problems, this utility model provides a red phosphorus conversion pot phosphorus scraping device.

The vertical scrapers are also fixed to one side of the scraping block, and the other side of the scraping block is provided with a secondary scraping blade, and the secondary scraping blade is parallel to the inner wall surface of the pot.

[0007] The number of scraper blocks is multiple, and the ratio of the number of scraper blocks to the number of vertical scrapers is greater than 3:1.

[0008] The projection of the scraper block onto the radial section of the cookware is an L-shape after at least one bend.

[0009] The radial scraper consists of multiple pieces, with adjacent radial scrapers fixed together by a cascaded guide plate, and the main scraping blade is also disposed on the surface of the cascaded guide plate.

[0010] The number of radial scrapers is 8.

[0011] The red phosphorus conversion pot scraping device also includes a pot lid, which covers the open end of the pot, and the spindle passes through the pot lid.

[0012] The red phosphorus conversion pot scraping device also includes a sealing gasket, which is sandwiched between the pot and the pot lid.

[0013] The sealing gasket is made of metal.

[0014] The beneficial effects of this utility model are as follows: by adopting the technical solution provided by this utility model, the outer contour of the scraping device is at least partially parallel to the inner wall surface of the pot, and the outer contour of the scraping device is close to the inner wall surface of the pot, so that the scraping device can rotate along the inner wall surface of the pot, fully and thoroughly scrape off the red phosphorus adhering to the inner wall of the pot, improve the scraping efficiency, reduce material waste, and make the material easy to transfer.

[0017] The technical solution of this utility model will be further described below with reference to the accompanying drawings, but the scope of protection claimed is not limited to the description. This utility model provides a phosphorus scraping device for a red phosphorus conversion pot, such as Figures 1 to 3 As shown, the red phosphorus conversion pot scraping device is used to scrape off the red phosphorus adhering to the inner wall surface of the pot 1. The red phosphorus conversion pot scraping device includes a spindle 3, a radial scraper 4 and a vertical scraper 5. One end of the radial scraper 4 is fixedly connected to the upper end of the spindle 3, the other end of the radial scraper 4 is fixedly connected to one end of the vertical scraper 5, the other end of the vertical scraper 5 is fixedly connected to the lower end of the spindle 3, and at least one side of the vertical scraper 5 is parallel to the inner wall surface of the pot 1. At least one side of the radial scraper 4 is provided with a main scraping blade 6.

[0018] By adopting the technical solution provided by this utility model, the outer contour of the scraping device is at least partially parallel to the inner wall surface of the pot, and the outer contour of the scraping device is close to the inner wall surface of the pot, so that the scraping device can rotate along the inner wall surface of the pot, fully and thoroughly scraping off the red phosphorus adhering to the inner wall of the pot, improving the scraping efficiency, reducing material waste, and making the material easy to transfer.

[0019] Specifically, there are multiple vertical scrapers 5, which are arranged at equal intervals around the core shaft 3. The vertical scrapers 5 are also fixed to one side of the scraping block 7. The other side of the scraping block 7 is provided with a secondary scraping blade 8, and the secondary scraping blade 8 is parallel to the inner wall surface of the pot 1.

[0020] The preferred number of scraper blocks 7 is multiple, and the ratio of the number of scraper blocks 7 to the number of vertical scrapers 5 is greater than 3:1. The projection of the scraper blocks 7 on the radial section of the cookware 1 is an L-shape after at least one bend.

[0021] In addition, there are multiple radial scrapers 4, with adjacent radial scrapers 4 fixed together by cascaded guide plates 9, and the main scraper blade 6 is also disposed on the surface of the cascaded guide plates 9. There are a total of 8 radial scrapers 4. Using the technical solution of this utility model, when the scraping mechanism rotates, the main scraper blade 6 can cut the clumped material and break it up, thereby fully and thoroughly scraping away the material adhering to the inner wall of the pot, making it easier to transfer the material to the next process.
