A transportation device for phosphate production with a drying function

Abstract

The present invention relates to the technical field of phosphate production, and particularly to a transportation device for phosphate production with a drying function. It includes a mobile rack, an electric push rod, and a support frame. Electric push rods are installed on both mobile racks, and a support frame is connected between the telescopic rods of the electric push rods. A movable frame is slidably arranged on the support frame. By preliminarily drying the phosphate during transportation, the present invention effectively reduces the moisture content in the phosphate, especially for the part that fails to be fully centrifuged dry in the central area of the centrifuge filter bag, improving the overall solid-liquid separation effect. Moreover, since the moisture content of the phosphate entering the drying equipment is significantly reduced, the time required for the subsequent drying step is greatly shortened, improving production efficiency. The reduction of drying time directly leads to a decrease in energy consumption. For factories with large-scale production, this not only means cost savings but also contributes to environmental protection and the achievement of sustainable development goals.

Description

Technical Field

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

[0002] As an important chemical raw material, phosphate has a wide range of applications in multiple fields such as agriculture and industry. In the process of phosphate production, solid-liquid separation is a crucial step, which directly affects the quality and production efficiency of the final product. Traditionally, solid-liquid separation of phosphate is achieved in a solid-liquid centrifuge, where the liquid is separated from the solid phosphate by centrifugal force, and the solid phosphate remains in the centrifuge filter bag for recovery.

[0003] However, the existing process flow and technical means have certain limitations, especially facing challenges in 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 materials near the rotation center are subjected to a smaller centrifugal force, resulting in insufficient dehydration of the phosphate in this area and containing more residual liquid. When the residual liquid of the phosphate in the central area of the centrifuge filter bag is too much, it will not only affect the efficiency and quality of the subsequent drying step, prolong the drying time, but also increase energy consumption and raise production costs.

[0004] To address these problems, a transportation device for phosphate production with a drying function is 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 the quality of the product. This transportation device can perform preliminary drying treatment on the phosphate during the transfer process from the centrifuge to the drying equipment, reduce its water content, and then shorten the subsequent drying time, reduce energy consumption and production costs. Summary of the Invention

[0005] In view of this, the present invention provides a transportation device for phosphate production with a drying function, which can solve the drawbacks in the current phosphate production process that due to the possible insufficient dehydration of the phosphate in the central area of the centrifuge filter bag and containing more residual liquid, it not only affects the efficiency and quality of the subsequent drying step, prolongs the drying time, but also increases energy consumption and raises production costs.

[0006] The technical solution is as follows: A transportation device for phosphate production with a drying function includes a moving frame, electric push rods, and a support frame. Electric push rods are installed on both of the two moving frames. A support frame is connected between the telescopic rods of the electric push rods. A movable frame is slidably arranged on the support frame. A translation mechanism for driving the movable frame to translate is also arranged on the support frame. A toothed ring is rotatably arranged on the movable frame. A rotation mechanism for driving the toothed ring to rotate is also arranged on the movable frame. A locking mechanism is arranged on the toothed ring. The locking mechanism is used to fasten the U-shaped rod connecting the centrifuge filter bag to the fixed frame, so as to drive the transportation of the phosphate in the centrifuge filter bag. A first servo motor is installed on the movable frame. A stirring frame is also rotatably installed on the movable frame. The stirring frame is used to stir the phosphate in the centrifuge filter bag. The stirring frame is connected to the output shaft of the first servo motor. Air outlet holes are spacedly arranged on the stirring frame. A channel is opened inside the stirring frame. The channel is communicated with the air outlet holes. A hollow frame is connected to the movable frame. The hollow frame is rotatably connected to the stirring frame and is communicated with the channel. An air delivery mechanism and an exhaust mechanism are also arranged on the movable frame. The air delivery mechanism is used to input hot air into the hollow frame. The hot air heats the residual liquid in the centrifuge filter bag through the channel and the air outlet holes. The exhaust mechanism is used to discharge the steam in the centrifuge filter bag.

[0007] Further explanation: The translation mechanism includes a lead screw, a second servo motor and a gearbox. Lead screws are symmetrically and rotatably arranged on the support frame. The movable frame is threadedly connected to the lead screws. Second servo motors are symmetrically arranged on the support frame. Gearboxes are also symmetrically arranged on the support frame. The input end of the gearbox is connected to the output shaft of the second servo motor. The output end of the gearbox is connected to the lead screw.

[0008] Further explanation; The rotation mechanism includes a third servo motor and a full gear. A third servo motor is installed on the movable frame. A full gear is connected to the output shaft of the third servo motor. The full gear meshes with the toothed ring.

[0009] Further explanation: The locking mechanism includes a first mounting frame, a first hook plate, a first torsion spring, a support bar, a second hook plate, a second torsion spring, a second mounting frame and a limiting member. First mounting frames are spacedly installed at the bottom of the toothed ring. A first hook plate is rotatably arranged on the first mounting frame. A first torsion spring is connected between the first hook plate and the first mounting frame. A support bar is hooked on the first hook plate. A groove is opened on the support bar. The groove is adapted to the U-shaped rod. A second hook plate is rotatably installed on the support bar. A second torsion spring is installed between the second hook plate and the support bar. Second mounting frames are also spacedly installed at the bottom of the toothed ring. The second hook plate is hooked on the second mounting frame. A limiting member is arranged at the bottom of the toothed ring. The limiting member is used to limit the first hook plate and the second hook plate.

[0010] Further explanation: The limiting member includes a clamping plate, a first spring and a clamping rod. The clamping plates are slidably arranged at intervals at the bottom of the toothed ring. The number of clamping plates is the sum of the numbers of the first mounting frame and the second mounting frame. The bottom of the clamping plate is set as an arc surface, and the arc surface at the bottom of the clamping plate is used to contact the U-shaped rod. A first spring is connected between the clamping plate and the toothed ring, and a clamping rod is connected to the clamping plate. Card slots are formed on both the first hook plate and the second hook plate. By inserting the clamping rod into the card slot, the first hook plate and the second hook plate are limited.

[0011] Further explanation: The air delivery mechanism includes an air pump, a heater and an air delivery pipe. An air pump and a heater are installed on the movable frame. The air outlet of the air pump is communicated with the inlet of the heater, and the outlet of the heater is communicated with the hollow frame through the air delivery pipe.

[0012] Further explanation: The exhaust mechanism includes an exhaust pipe and a fan. An exhaust pipe is installed on the movable frame. The exhaust pipe is used for discharging the steam in the centrifuge filter bag. A fan is installed on the exhaust pipe, and the fan is used for sucking the steam in the centrifuge filter bag into the exhaust pipe.

[0013] Further explanation: It further includes a blocking mechanism. The blocking mechanism includes a diaphragm, a sealing gasket and a second spring. A diaphragm is connected to the bottom of the movable frame. The diaphragm is used to block the steam in the centrifuge filter bag from being discharged. A sealing gasket is connected to the bottom end of the diaphragm, and a second spring is connected between the sealing gasket and the bottom of the movable frame.

[0014] The beneficial effects of the present invention are as follows: 1. By performing preliminary drying treatment on the phosphate during transportation, the present invention effectively reduces the moisture content in the phosphate, especially for the part in the central area of the centrifuge filter bag that fails to be fully dewatered, improves the overall solid-liquid separation effect, and since the moisture content of the phosphate entering the drying equipment is significantly reduced, the time required for the subsequent drying step is greatly shortened, the production efficiency is improved, and the reduction of the drying time directly leads to the reduction of energy consumption. For large-scale production factories, this not only means cost savings but also contributes to environmental protection and the achievement of sustainable development goals.

[0015] 2. The present invention integrates a variety of automated components (such as servo motors, air pumps, heaters, etc.), realizing an integrated operation process from solid-liquid separation to preliminary drying and then to final drying, reducing manual intervention and improving the automation level of the production line.

[0016] 3. By setting the blocking mechanism, the present invention can use the diaphragm to block the steam from being discharged between the bottom of the movable frame and the top of the fixed frame, thereby protecting the parts of the locking mechanism to prevent corrosion risks caused by steam residue on the parts of the locking mechanism.

[0032] See Figure 2As shown in the figure, the translation mechanism includes a lead screw 501, a second servo motor 502, and a gearbox 503.

The input end of the gearbox 503 is connected to the output shaft of the second servo motor 502, and the output end of the gearbox 503 is connected to the lead screw 501. By using the second servo motor 502 to drive the lead screw 501 to rotate through the gearbox 503, the lead screw 501 can drive the movable frame 4 to translate on the support frame 3.

[0033] See Figure 3 As shown in the figure, the rotation mechanism includes a third servo motor 701 and a full gear 702. The third servo motors 701 are symmetrically installed on the left and right sides of the top of the movable frame 4. The output shaft of the third servo motor 701 is connected to the full gear 702, and the full gear 702 meshes with the toothed ring 6. By driving the full gear 702 to rotate through the third servo motor 701, the full gear 702 can drive the toothed ring 6 to rotate.

[0034] See Figures 3-6 As shown in the figure, the locking mechanism includes a first mounting bracket 801, a first hook plate 802, a first torsion spring 803, a support bar 804, a second hook plate 806, a second torsion spring 807, a second mounting bracket 808, and a limiting member. Four first mounting brackets 801 are annularly and spacedly installed at the bottom of the toothed ring 6. The first hook plate 802 is rotatably arranged on the first mounting bracket 801. Two first torsion springs 803 are connected between the first hook plate 802 and the first mounting bracket 801. The lower side of the first hook plate 802 hooks the support bar 804. A groove 805 is opened in the middle of the top of the support bar 804, and the groove 805 is adapted to the U-shaped rod 103. The second hook plate 806 is rotatably installed at one end of the support bar 804 away from the first hook plate 802. Two second torsion springs 807 are installed between the second hook plate 806 and the support bar 804. Four second mounting brackets 808 are also annularly and spacedly installed at the bottom of the toothed ring 6, and the upper side of the second hook plate 806 hooks on the second mounting bracket 808. The limiting member includes a clamping plate 8091, a first spring 8092, and a clamping rod 8093. Eight clamping plates 8091 are annularly and slidably arranged at the bottom of the toothed ring 6. The bottom of the clamping plate 8091 is arc-shaped, and the arc-shaped surface at the bottom of the clamping plate 8091 is used to contact the U-shaped rod 103. Three first springs 8092 are connected between the top of the clamping plate 8091 and the toothed ring 6. A clamping rod 8093 is connected to the upper side of the clamping plate 8091, and the bottom of the clamping rod 8093 is beveled. Slots 8094 are opened at the tops of both the first hook plate 802 and the second hook plate 806. By inserting the clamping rod 8093 into the slot 8094, the first hook plate 802 and the second hook plate 806 can be limited.

[0035] See Figure 10As shown in the figure, the air delivery mechanism includes an air pump 1401, a heater 1402, and an air delivery pipe 1403. The air pump 1401 and the heater 1402 are installed on the lower right part of the movable frame 4. The air pump 1401 is located on the right side of the heater 1402. The air outlet of the air pump 1401 is communicated with the inlet of the heater 1402. The outlet of the heater 1402 is communicated with the hollow frame 13 through the air delivery pipe 1403. The air pump 1401 is used to input gas into the heater 1402, so that the heater 1402 heats the gas. Then, the heated gas is input into the hollow frame 13 through the air delivery pipe 1403, so as to deliver hot air into the hollow frame 13.

[0036] See Figure 7 and Figure 9 As shown in the figure, the exhaust mechanism includes an exhaust pipe 1501 and a fan 1502. The exhaust pipe 1501 is installed on the lower left part of the movable frame 4. The exhaust pipe 1501 is used for discharging the steam in the centrifuge filter bag 101. A fan 1502 is installed at the bottom end of the exhaust pipe 1501. The fan 1502 is used to attract the steam in the centrifuge filter bag 101 into the exhaust pipe 1501.

[0037] During use, first move the moving frame 1 until the support frame 3 on the electric push rod 2 is 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 inside the centrifuge filter bag 101. Subsequently, use the solid-liquid centrifuge to separate the phosphate and the liquid in the centrifuge filter bag 101, discharging the liquid from the solid-liquid centrifuge while the phosphate remains in the centrifuge filter bag 101. Next, use the second servo motor 502 to drive the lead screw 501 to rotate through the gearbox 503, causing the lead screw 501 to drive the movable frame 4 to translate towards directly above the solid-liquid centrifuge until the movable frame 4 is directly above the solid-liquid centrifuge. Then, drive the full gear 702 to rotate through the third servo motor 701, thereby driving the toothed ring 6, the first mounting bracket 801, the first hook plate 802, and the support bar 804 to rotate (clockwise when viewed from above) until the support bar 804 is not on the same vertical line as the U-shaped rod 103 directly below (to prevent the support bar 804 from colliding with the U-shaped rod 103 after descending). Then, drive the support frame 3, the movable frame 4, the toothed ring 6, the first mounting bracket 801, the first hook plate 802, and the support bar 804 to descend through the electric push rod 2 until the bottom of the support bar 804 contacts the top of the fixing frame 102 on the centrifuge filter bag 101 (the centrifuge filter bag 101, the fixing frame 102, and the U-shaped rod 103 remain stationary). Next, drive the full gear 702 to rotate again through the third servo motor 701, thereby driving the toothed ring 6, the first mounting bracket 801, the first hook plate 802, the support bar 804, the second hook plate 806, the second mounting bracket 808, and the clamping plate 8091 to rotate (clockwise when viewed from above). When the arc surface at the bottom of the clamping plate 8091 contacts the U-shaped rod 103, the U-shaped rod 103 will squeeze the clamping plate 8091 and the clamping rod 8093 to move upward, compressing the first spring 8092, causing the clamping rod 8093 to leave the card slot 8094 of the second hook plate 806, thereby releasing the limit on the second hook plate 806 by the clamping rod 8093. When the U-shaped rod 103 contacts the second hook plate 806, the U-shaped rod 103 will squeeze the second hook plate 806 to rotate, deforming the second torsion spring 807, causing the second hook plate 806 to release the second mounting bracket 808. When the U-shaped rod 103 separates from the arc surface at the bottom of the clamping plate 8091, 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. After that, when the U-shaped rod 103 separates from the second hook plate 806, the second torsion spring 807 returns to its original state, and the second torsion spring 807 drives the second hook plate 806 to reverse and reset, causing the second hook plate 806 to re-hook the second mounting bracket 808. When the second hook plate 806 contacts the inclined surface at the bottom of the clamping rod 8093, the second hook plate 806 will squeeze the clamping rod 8093 and the clamping plate 8091 to move upward, compressing the first spring 8092. When the second hook plate 806 reverses and resets, the first spring 8092 returns to its original state,The first spring 8092 drives the clamping plate 8091 and the clamping rod 8093 to move downward for resetting, so that the clamping rod 8093 is reinserted into the card slot 8094 of the second hook plate 806, thereby limiting the second hook plate 806 by the clamping rod 8093, and thus buckling the U-shaped rod 103 between the first mounting bracket 801, the first hook plate 802, the support bar 804, the second hook plate 806 and the second mounting bracket 808. When the U-shaped rod 103 is directly above the groove 805 of the support bar 804 (as shown in, Figure 6 shown), the third servo motor 701 is driven to stop the rotation of the full gear 702, and then the electric push rod 2 is used to drive the support frame 3, the movable frame 4, the toothed ring 6, the first mounting bracket 801, the first hook plate 802 and the support bar 804 to rise and reset, so that the U-shaped rod 103 is inserted into the groove 805 of the support bar 804, and then the support bar 804 drives the centrifuge filter bag 101 and the fixing frame 102 to rise through the U-shaped rod 103;

[0038] Then, the second servo motor 502 drives the lead screw 501 to reverse through the gearbox 503, causing the lead screw 501 to drive the movable frame 4 to translate towards directly above the drying equipment, thereby driving the toothed ring 6, the first mounting bracket 801, the first hook plate 802, the support bar 804, the U-shaped rod 103, the fixed frame 102, and the centrifuge filter bag 101 to translate, so as to transport the phosphate in the centrifuge filter bag 101 until the movable frame 4 is directly above the drying equipment. During the translation of the movable frame 4 towards directly above the drying equipment, the groove 805 on the support bar 804 can limit the U-shaped rod 103, thereby improving the stability of the U-shaped rod 103, the fixed frame 102, and the centrifuge filter bag 101 and ensuring the smooth transportation of the phosphate. And during this period, the stirring frame 10 is driven to rotate by the first servo motor 9 (rotating counterclockwise when viewed from above), so that the stirring frame 10 stirs the phosphate in the centrifuge filter bag 101. At the same time, the hot air is sent into the hollow frame 13 through the air pipe 1403 by using the air pump 1401 and the heater 1402, and the hot air is discharged into the centrifuge filter bag 101 through the channel 12 and the air outlet holes 11, so as to heat the remaining liquid in the centrifuge filter bag 101, so that the remaining liquid forms steam and is discharged after heating, thereby drying the phosphate in the centrifuge filter bag 101, so as to perform a preliminary drying treatment on the phosphate, reduce its water content, and then shorten the subsequent drying time, reduce energy consumption and production costs. At the same time, the steam in the centrifuge filter bag 101 is attracted into the exhaust pipe 1501 and discharged by the fan 1502. When the movable frame 4 is directly above the drying equipment, the electric push rod 2 is used to drive the support frame 3, the movable frame 4, the toothed ring 6, the first mounting bracket 801, the first hook plate 802, and the support bar 804 to descend, so that the support bar 804 drives the centrifuge filter bag 101 to descend to a suitable position, and then the buckle at the bottom of the centrifuge filter bag 101 is opened, so that the preliminarily dried phosphate in the centrifuge filter bag 101 falls into the drying equipment for subsequent phosphate drying treatment;

[0039] After closing the buckle at the bottom of the centrifuge filter bag 101, the electric push rod 2 is used to drive the support frame 3, the movable frame 4, the toothed ring 6, the first mounting frame 801, the first hook plate 802 and the support bar 804 to rise and reset, so that the support bar 804 drives the centrifuge filter bag 101 to rise. Then, the second servo motor 502 drives the lead screw 501 to rotate through the gearbox 503, so that the lead screw 501 drives the movable frame 4 to translate towards the directly above of the solid-liquid centrifuge, thereby driving the toothed ring 6, the first mounting frame 801, the first hook plate 802, the support bar 804, the U-shaped rod 103, the fixed frame 102 and the centrifuge filter bag 101 to translate until the movable frame 4 is directly above the solid-liquid centrifuge. Then, the electric push rod 2 is used to drive the support frame 3, the movable frame 4, the toothed ring 6, the first mounting frame 801, the first hook plate 802 and the support bar 804 to descend, so that the support bar 804 drives the centrifuge filter bag 101 to descend until the centrifuge filter bag 101 returns to the solid-liquid centrifuge again, and the U-shaped rod 103 leaves the groove 805 of the support bar 804. Then, the third servo motor 701 is used to drive the full gear 702 to rotate again, thereby driving the toothed 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 clamping plate 8091 to rotate (clockwise rotation when viewed from top to bottom). When the arc surface at the bottom of the clamping plate 8091 contacts the U-shaped rod 103, the U-shaped rod 103 will squeeze the clamping plate 8091 and the clamping rod 8093 to move upward, and the first spring 8092 is compressed, so that the clamping rod 8093 leaves the clamping groove 8094 of the first hook plate 802, thereby releasing the limit of the clamping rod 8093 on the first hook plate 802. When the U-shaped rod 103 contacts the first hook plate 802, the U-shaped rod 103 will squeeze the first hook plate 802 to rotate, and the first torsion spring 803 is deformed, so that the first hook plate 802 releases the first mounting frame 801. When the U-shaped rod 103 separates from the arc surface at the bottom of the clamping plate 8091, 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. After that, when the U-shaped rod 103 separates from the first hook plate 802, the first torsion spring 803 returns to its original state, and the first torsion spring 803 drives the first hook plate 802 to reverse and reset, so that the first hook plate 802 hooks the first mounting frame 801 again. When the first hook plate 802 contacts the inclined surface at the bottom of the clamping rod 8093, the first hook plate 802 will squeeze the clamping rod 8093 and the clamping plate 8091 to move upward, and the first spring 8092 is compressed. When the first hook plate 802 reverses and resets, 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 reinserted into the clamping groove 8094 of the first hook plate 802, thereby limiting the first hook plate 802 by the clamping rod 8093, so that the U-shaped rod 103 leaves 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.After that, the third servo motor 701 is used to drive the full gear 702 to stop rotating. Finally, the electric push rod 2 is used to drive the support frame 3, the movable frame 4, the toothed 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.

[0040] See Figure 11 As shown, it further includes a blocking mechanism, which includes a diaphragm 16, a gasket 17 and a second spring 18. A diaphragm 16 is connected to the bottom of the movable frame 4. The diaphragm 16 is used to block the steam in the centrifuge filter bag 101 from discharging, so as to prevent the steam from discharging between the bottom of the movable frame 4 and the top of the fixed frame 102, thereby protecting the parts of the locking mechanism. A gasket 17 is connected to the bottom end of the diaphragm 16. A second spring 18 is connected between the top of the gasket 17 and the bottom of the movable frame 4, and the second spring 18 is located outside the diaphragm 16.

[0041] By setting the 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 gasket 17 to descend. When the gasket 17 contacts the top of the fixed frame 102 on the centrifuge filter bag 101, the fixed frame 102 will hold the gasket 17 to stop the descent of the gasket 17. 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 gasket 17 to make the gasket 17 closely adhere to the top of the fixed frame 102, so as to seal between the gasket 17 and the top of the fixed frame 102. After that, when the liquid in the centrifuge filter bag 101 forms steam, the diaphragm 16 can be used to block the steam from discharging 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 risk. 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 gasket 17 to rise and reset through the second spring 18, so that the gasket 17 is separated from the top of the fixed frame 102 on the centrifuge filter bag 101.

[0042] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention.
