Description

Technical Field

[0001] The utility model relates to the technical field of mineral processing equipment, in particular to a phosphogypsum water washing device. Background Technique

[0002] A phosphogypsum water washing device is a device used to process phosphogypsum, mainly for removing impurities in phosphogypsum to improve its purity. Phosphogypsum is a by-product in the production process of phosphoric acid and usually contains a certain amount of impurities, such as sulfates, organic substances, unreacted phosphates, etc. The water washing device removes these impurities through physical and chemical methods to meet the requirements of subsequent applications.

[0003] Although the current technology has many advantages, the disadvantages of the current technology are that traditional devices are mostly composed of a stirring tank, a sedimentation tank and a filtration tank, which will result in a large floor area required for the device. This may limit the layout and expansion space of other devices or production lines, affecting production efficiency and flexibility. Moreover, in the initial stage of factory construction, a large floor area means a greater investment in the initial stage of factory construction, increasing the investment risk and factory construction cost. At the same time, traditional devices only filter the impurities in the same batch of phosphogypsum, and unstable water washing conditions will cause different particles to be affected to different degrees during the treatment process, resulting in different sizes of phosphogypsum. Different-sized phosphogypsum may cause the surface of the gypsum board to be uneven, affecting the appearance and quality. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a phosphogypsum water washing device to solve the problems put forward in the above background technique.

[0006] As a preferred embodiment, the mixing mechanism includes a second motor. The second motor is provided with a second rotating shaft through an output shaft. The second rotating shaft is movably embedded in the inner surface of the mixing tank. A stirrer is fixedly installed on the outer surface of the second rotating shaft. The bottom of the second motor is fixedly connected to a support plate. The bottom of the support plate is fixedly connected to a plurality of support rods. A plurality of third filtering holes are formed in the outer surface of the mixing tank near the top. A water tank is fixedly connected to one side of the mixing tank near the plurality of third filtering holes. A sewage pipe is fixedly connected to the outer surface of the water tank.

[0009] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0010] The present utility model uses a spiral plate to realize the movement of the product inside the feeding pipe, and then uses the different sizes of the second filtering holes in the material distribution pipe to realize the multi-stage separation and screening of the product. The grading screening can ensure that the final product has a uniform particle size, improve the uniformity of the product to a certain extent, ensure the smooth surface of the gypsum board, and ensure the beauty and quality of the gypsum board to a certain extent. Moreover, this equipment does not add a sedimentation tank and a filtration tank, so it does not require a large floor area, reduces the investment cost in the initial stage of plant construction, and reduces the investment risk to a certain extent.

[0019] As Figure 1 and Figure 2As shown in the figure, the mixing mechanism includes a second motor 6. The second motor 6 is provided with a second rotating shaft 7 through an output shaft. The second rotating shaft 7 is movably embedded in the inner surface of the mixing tank 1. A stirrer 20 is fixedly installed on the outer surface of the second rotating shaft 7. The bottom of the second motor 6 is fixedly connected to a support plate 5. The bottom of the support plate 5 is fixedly connected to a plurality of support rods 4. A plurality of third filter holes 17 are formed in the outer surface of the mixing tank 1 near the top. A water tank 18 is fixedly connected to one side of the mixing tank 1 near the plurality of third filter holes 17. A sewage pipe 19 is fixedly connected to the outer surface of the water tank 18. The second rotating shaft 7 can transmit the power of the second motor 6 to the stirrer 20 to make the stirrer 20 rotate.

[0020] As Figure 2 and Figure 3 shown in the figure, the fixing assembly 10 is fixedly connected to the outer surface of the mixing tank 1. The first rotating shaft 12 is movably embedded in the inner surface of the feeding pipe 21. The first rotating shaft 12 can transmit the power of the first motor 11 to the spiral plate 13 to make the spiral plate 13 rotate.

[0021] As Figure 1 shown in the figure, a plurality of support rods 4 are fixedly connected to the top of the mixing tank 1. The support rods 4 can support the support plate 5 to provide a good working environment for the second motor 6.

[0022] Working principle: This device is a phosphogypsum water washing device. When in use, raw materials of the same batch are introduced into the mixing tank 1, and then water is continuously injected into the mixing tank 1 to keep the water level slightly higher than the third filtration hole 17 all the time. The cooperation of the support rod 4 and the support plate 5 can support the second motor 6, and the second motor 6 is started. The second motor 6 drives the second rotating shaft 7 to rotate through the output shaft, and the second rotating shaft 7 drives the stirrer 20 to stir the raw materials inside the mixing tank 1, so that the raw materials are mixed with water. The impurities that can float on the water surface in the raw materials will enter the water tank 18 through the third filtration hole 17 along with the flow of water, and then the impurities floating on the water surface are discharged by the sewage pipe 19. When the raw materials and water are mixed well, the stirrer 20 is stopped to make the raw materials inside the mixing tank 1 precipitate. The fixed rod 8 and the fixed plate 9 can support the first motor 11, and then the first motor 11 is started. The first motor 11 drives the first rotating shaft 12 to rotate through the output shaft, and the first rotating shaft 12 drives the spiral plate 13 to rotate inside the feeding pipe 21. Then the gate valve 3 is slowly opened, and the raw materials inside the mixing tank 1 will first enter the feeding pipe 2. Because the diameter of the second filtration hole 16 corresponding to the first-stage distribution pipe 15 is very small, the product cannot pass through, and then the water will flow out from the first-stage distribution pipe 15. By controlling the opening degree of the gate valve 3, the water is only discharged from the inside of the first-stage distribution pipe 15. Because of the first filtration hole 14 opened on the spiral plate 13, when the spiral plate 13 rotates, the product in the water can be fished out. And the diameter of the second filtration hole 16 in the distribution pipe 15 gradually increases. Therefore, when the product is driven by the spiral plate 13, the product will enter the distribution pipe 15 and be discharged according to the particle size respectively, and the larger product will be discharged from the feeding pipe 21, realizing the multi-stage separation and screening of products of the same batch. The fixing assembly 10 can provide stability for the device and ensure the normal operation of the device.

[0023] The above are only the preferred embodiments of the present invention, and do not limit the present invention in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
