Description

Technical Field

[0001] The invention relates to the technical field of phosphate production, and in particular to a phosphate production transportation device with a drying function. Background Art

[0002] As an important chemical raw material, phosphate is widely used in agriculture, industry and other fields. In the phosphate production process, solid-liquid separation is a crucial link, which is directly related to the quality of the final product and production efficiency. Traditionally, the solid-liquid separation of phosphate is achieved in a solid-liquid centrifuge, which uses centrifugal force to separate the liquid from the solid phosphate, so that the solid phosphate remains in the centrifuge filter bag for recovery.

[0003] However, the existing process flow and technical means have certain limitations, especially in terms of improving the solid-liquid separation effect. Specifically, when using a centrifuge to process phosphate, due to the physical property that the centrifugal force increases with the increase of the rotation radius, the material close to the center of rotation is subjected to a smaller centrifugal force, which causes the phosphate in this area to not be fully dried and contains more residual liquid; when there is too much residual phosphate liquid in the center area of ​​the centrifuge filter bag, it will not only affect the efficiency and quality of the subsequent drying steps and prolong the drying time, but also increase energy consumption and push up production costs.

[0004] In response to these problems, a phosphate production transportation device with a drying function has been proposed, aiming to solve the problem of high water content of phosphate after solid-liquid separation, thereby improving the efficiency of the entire production process and product quality. This transportation device can perform preliminary drying treatment on phosphate during the process of transferring phosphate from the centrifuge to the drying equipment, reduce its water content, and thus shorten the subsequent drying time, reducing energy consumption and production costs. Summary of the invention

[0036] When in use, first push the movable frame 1 to move until the support frame 3 on the electric push rod 2 is located directly above the solid-liquid centrifuge and the drying equipment, then pour the liquid containing phosphate into the solid-liquid centrifuge, so that the liquid containing phosphate is in the centrifuge filter bag 101, then use the solid-liquid centrifuge to separate the phosphate and liquid in the centrifuge filter bag 101, so that the liquid is discharged from the solid-liquid centrifuge, while the phosphate remains in the centrifuge filter bag 101, then use the second servo motor 502 to drive the screw rod 501 to rotate through the gear box 503, so that the screw rod 501 drives the movable frame 4 to translate toward directly above the solid-liquid centrifuge until the movable frame 4 is directly above the solid-liquid centrifuge, then through the first servo motor 502, the gear box 503 drives the screw rod 501 to rotate, so that the screw rod 501 drives the movable frame 4 to translate toward directly above the solid-liquid centrifuge, until the movable frame 4 is directly above the solid-liquid centrifuge, The third servo motor 701 drives the full gear 702 to rotate, thereby driving the gear ring 6, the first mounting frame 801, the first hook plate 802 and the support bar 804 to rotate (clockwise when viewed from top to bottom) until the support bar 804 is not in the same vertical line with the U-shaped rod 103 directly below (to prevent the support bar 804 from colliding with the U-shaped rod 103 after it descends), and then the electric push rod 2 drives the support frame 3, the movable frame 4, the gear ring 6, the first mounting frame 801, the first hook plate 802 and the support bar 804 to descend until the bottom of the support bar 804 contacts the top of the fixed frame 102 on the centrifuge filter bag 101 (the centrifuge filter bag 101, the fixed frame 102 and the U-shaped rod 103 are stationary), and then the third servo motor 7 is used again. 01 drives the full gear 702 to rotate, thereby driving the gear ring 6, the first mounting frame 801, the first hook plate 802, the support bar 804, the second hook plate 806, the second mounting frame 808 and the card plate 8091 to rotate (clockwise rotation when viewed from top to bottom).

When the first hook plate 802 is reversed and reset, the first spring 8092 returns to its original state, and the first spring 8092 drives the clamping plate 8091 and the clamping rod 8093 to move downward and reset, so that the clamping rod 8093 is clamped into the clamping groove 8094 of the first hook plate 802 again, so that the clamping rod 8093 limits the first hook plate 802, so that the U-shaped rod 103 leaves from between the first mounting frame 801, the first hook plate 802, the support bar 804, the second hook plate 806 and the second mounting frame 808.Then, the third servo motor 701 drives the full gear 702 to stop rotating, and finally the electric push rod 2 drives the support frame 3, the movable frame 4, the gear ring 6, the first mounting frame 801, the first hook plate 802 and the support bar 804 to rise and reset, so that the bottom of the support bar 804 is separated from the top of the fixed frame 102 on the centrifuge filter bag 101.

[0037] See also Fig.11 As shown, a blocking mechanism is also included, which includes a diaphragm 16, a sealing gasket 17 and a second spring 18; the bottom of the movable frame 4 is connected to the diaphragm 16, and the diaphragm 16 is used to block the discharge of steam in the centrifuge filter bag 101 to prevent the steam from being discharged from the bottom of the movable frame 4 and the top of the fixed frame 102, thereby protecting the parts of the locking mechanism; the bottom end of the diaphragm 16 is connected to the sealing gasket 17; the second spring 18 is connected between the top of the sealing gasket 17 and the bottom of the movable frame 4, and the second spring 18 is located on the outside of the diaphragm 16.

[0038] By setting a blocking mechanism, when the movable frame 4 descends and gradually approaches the centrifuge filter bag 101, the movable frame 4 will drive the diaphragm 16 and the sealing gasket 17 to descend. When the sealing gasket 17 contacts the top of the fixed frame 102 on the centrifuge filter bag 101, the fixed frame 102 will support the sealing gasket 17 to stop the sealing gasket 17 from descending. When the movable frame 4 continues to descend, the second spring 18 is compressed. Under the elastic force of the second spring 18, the second spring 18 will apply pressure to the sealing gasket 17 to make the sealing gasket 17 close to the top of the fixed frame 102, so as to seal the sealing gasket 17 and the top of the fixed frame 102. When the liquid in the centrifuge filter bag 101 forms steam, the diaphragm 16 can be used to prevent the steam from being discharged from between the bottom of the movable frame 4 and the top of the fixed frame 102, thereby protecting the parts of the locking mechanism to prevent the steam from remaining on the parts of the locking mechanism and causing corrosion risks; when the movable frame 4 rises and gradually moves away from the centrifuge filter bag 101, the second spring 18 will gradually return to its original state. After the second spring 18 is reset, the movable frame 4 will drive the diaphragm 16 and the sealing gasket 17 to rise and reset through the second spring 18, so that the sealing gasket 17 is separated from the top of the fixed frame 102 on the centrifuge filter bag 101.
