Description

Technical Field

[0001] The utility model relates to a bucket elevator for conveying wet phosphogypsum. Background Art

[0002] Phosphogypsum is a solid waste discharged during the production of phosphate fertilizer and phosphoric acid. In addition to the main component calcium sulfate, phosphogypsum also contains a small amount of phosphoric acid, silicon, magnesium, iron, aluminum, organic impurities, etc. Phosphogypsum is a solid waste discharged during the production of phosphate fertilizer and phosphoric acid. It is a powdery material that exists in the form of particles.

[0003] In the process of transporting phosphogypsum, a bucket elevator is needed to lift the phosphogypsum to a high place. However, the existing bucket elevator is only suitable for transporting dry phosphogypsum. When transporting wet phosphogypsum, a "bucket sticking" phenomenon will occur, which greatly affects the transportation efficiency. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a bucket elevator for conveying wet phosphogypsum, which is used to solve the "bucket sticking" problem generated when conveying wet phosphogypsum.

[0005] In order to solve the above problems, the utility model proposes a bucket elevator for conveying wet phosphogypsum, including a top cover shell, a machine shell, a lifting belt and a hopper. The hopper is fan-shaped, a rotating shaft is installed at one end of the hopper, a scraper is provided at the bottom of the hopper, the upper end of the scraper is fixedly connected to the rotating shaft, and torsion springs and guide wheels are respectively installed at both ends of the rotating shaft. An arc guide bar is provided in the top cover shell, one end of the guide bar is hinged to the top cover shell, a limiting column and a top block are fixedly connected in the top cover shell, an anti-slip column is fixedly connected to the top block and the guide bar, a spring is provided between the top block and the guide bar, the spring is sleeved on the anti-slip column, and the spring pushes the guide bar to be pressed against the guide wheel.

[0006] The beneficial effect of the utility model is that a rotatable scraper is arranged in the hopper, and when the hopper moves to the top of the bucket elevator, the scraper can rotate automatically, and the rotating scraper is used to clean up the materials adhered in the hopper to avoid the bucket sticking phenomenon.

[0014] like Figures 1 to 4 As shown, a bucket elevator for conveying wet phosphogypsum comprises a top cover shell 1, a casing 4, a lifting belt 3 and a hopper 2, wherein the hopper 2 is fan-shaped, a rotating shaft 12 is installed at one end of the hopper 2, a scraper 15 is provided at the bottom of the hopper 2, the upper end of the scraper 15 is fixedly connected to the rotating shaft 12, a torsion spring 14 and a guide wheel 10 are respectively mounted at both ends of the rotating shaft 12, an arc-shaped guide bar 6 is provided in the top cover shell 1, one end of the guide bar 6 is hinged to the top cover shell 1, a limiting column 5 and a top block 7 are fixedly connected in the top cover shell 1, an anti-slip column 8 is fixedly connected to the top block 7 and the guide bar 6, a spring 9 is provided between the top block 7 and the guide bar 6, the spring 9 is sleeved on the anti-slip column 8, and the spring 9 pushes the guide bar 6 to be pressed against the guide wheel 10. In normal state, the spring 9 pushes the guide bar 6 to press on the limit column 5. When the guide wheel 10 passes by the guide bar 6, one end of the guide bar 6 is lifted by the guide wheel 10, so that the spring 9 is compressed.

[0015] When the utility model is used: Figure 1 and 2 As shown, after the wet phosphogypsum is fed into the bucket elevator, the lifting belt 3 moves with the hopper 2 to lift the wet phosphogypsum. When the hopper 2 moves to the position of the arc-shaped guide bar 6 in the top cover 1, the phosphogypsum will be discharged from the bucket elevator discharge hopper 2 due to gravity. Then, the guide wheel 10 at one end of the hopper 2 rubs against the guide bar 6, and rotates with the rotation of the hopper 2. The rotating guide wheel 10 drives the scraper 15 to rotate and the torsion spring 14 to twist through the rotating shaft 12. With the rotation of the scraper 15, the residual phosphogypsum adhered to the hopper 2 is scraped into the discharge hopper 2. When the guide wheel 10 moves out of the guide bar 6, the torsion spring 14 drives the scraper 15 to rebound quickly and hit the hopper 2, so that the phosphogypsum adhered to the scraper 15 is also shaken down, thereby completely shaking off the wet phosphogypsum adhered to the hopper 2.

[0016] A flexible scraper 13 is fixedly connected to the scraper 15, so as to improve the cleaning effect of the hopper 2.

[0017] The scraper blade 13 is made of polytetrafluoroethylene, and the scraper blade 13 is adhered to the scraper plate 15. Polytetrafluoroethylene has a self-lubricating effect, which weakens the adsorption force of phosphogypsum and makes the phosphogypsum adhered to the scraper blade 12 easier to be shaken off.

[0018] A plurality of through holes are provided on the scraper 15. This structure is used to reduce the weight of the scraper 15, lighten the load of the hoist, and increase the service life of the device, and is more conducive to turning over the scraper 15.

[0019] A rubber ring 11 is provided outside the guide wheel 10. The rubber ring 11 increases the friction between the guide wheel 10 and the guide bar 6.

[0020] The above embodiments are only preferred technical solutions of the present invention and should not be regarded as limitations of the present invention. The protection scope of the present invention shall be the technical solutions recorded in the claims, including equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, equivalent replacement improvements within this scope are also within the protection scope of the present invention.
