Description

Technical Field

[0001] This invention relates to the field of dryer technology, specifically to an ore dryer. Background Technology

[0002] Ore refers to a mineral aggregate from which useful components can be extracted or which has certain usable properties. It can be divided into metallic minerals and non-metallic minerals. After the ore is mined from the mine, it needs to be washed with water by a washing machine before beneficiation and impurity removal to remove impurities such as mud from the ore. The washed ore needs to be dried before it can enter the next stage of beneficiation equipment for beneficiation.

[0003] In existing technologies, rotary drum dryers are commonly used to dry ores. During the process of conveying the ore into the rotary drum dryer, the ore initially accumulates at the bottom of the drum, resulting in uneven distribution. The ore on the outer edges receives the hot air preferentially, while some hot air is blocked from reaching the ore on the inner edges, reducing the amount of heat received. Furthermore, as the ore moves towards the discharge port within the dryer, larger ores cannot be carried to higher positions by the rotating drum. Consequently, larger ores often rise to the middle of the dryer before falling back down, remaining at the bottom of the smaller ores. Therefore, existing rotary drum dryers cannot evenly distribute the ore, resulting in uneven drying and affecting the quality of the ore before it enters the next stage of beneficiation. Summary of the Invention

[0004] The purpose of this invention is to provide an ore dryer to solve the problem of uneven drying caused by the inability of the ore dryer to distribute the ore evenly.

The support ring and the support wheel are slidably connected.

[0026] A drying process based on the aforementioned ore dryer includes the following specific steps:

[0027] A. Start the power unit to make the drying drum rotate, blow hot air into the dryer from the air inlet pipe, and use the diversion component to make hot air flow into each chamber of the drying drum. The hot air is finally dissipated from the air outlet pipe.

[0028] B. The ore to be dried is conveyed from the ore inlet pipe into the dryer. The material control component is started to control the amount of ore to be dried per unit time. The gear component is used to make each flap component flip and stir the ore, and then convey it towards the discharge sealing cover.

[0029] C. Remove the dried ore from the ore outlet pipe.

[0030] Compared with the prior art, the beneficial effects of the present invention are:

[0031] 1. Multiple drying chambers are arranged in a ring array. The ore enters from the inlet pipe and passes through the inlet channel. When the opening of the drying chamber connects with the opening of the inlet channel, the ore falls from the inlet channel into the drying chamber. Then, with the rotation of the drying cylinder, the next drying chamber connects with the inlet channel, and the ore falls into the next drying chamber. In this way, the same mass of ore is divided into multiple portions and dried in the drying cylinder. This can prevent a large amount of ore from accumulating and causing uneven drying.

[0032] 2. By installing an electric telescopic rod and a telescopic baffle, activating the electric telescopic rod can move the telescopic baffle up and down, thereby changing the opening size of the connection between the ore inlet channel and the drying chamber. This controls the amount of ore entering the drying chamber. Furthermore, when the ore passes through the bottom of the telescopic baffle, it is flattened by the baffle, which can prevent different ores from entering the drying chamber at different times due to different mass flow rates, thus avoiding excessive differences in the amount of ore accumulated in different areas of the drying chamber and resulting in uneven ore distribution.

[0033] 3. By setting up a distribution plate, connecting pipe and air distribution pipe, hot air is distributed through the distribution plate. The hot air distributed from the distribution hole flows to the connecting pipe, then from the connecting pipe to the air distribution pipe, and then flows out from the air outlet on the air distribution pipe. The air distribution pipe passes through the middle of the drying chamber, and the hot air dries the ore in the middle, increasing the amount of contact between each ore and the hot air, improving the uniformity of ore drying, and finally the hot air is discharged from the air diffuser pipe.

[0034] 4. By incorporating guide plates, the rotation of the drying drum drives the air distribution pipe and the first transmission gear to move. The first transmission gear meshes with the first gear ring, and as it moves along the inner ring, it rotates, causing the air distribution pipe to rotate. This rotation, in turn, moves the guide plates, which move along the inner wall of the drying chamber, turning the ore inside and increasing the contact between the ore and the hot air, thus ensuring thorough drying.

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] Please see Figures 1 to 10This invention provides a technical solution: an ore dryer, comprising: a support base 1 for supporting the entire dryer and having control components mounted on its surface; a feeding assembly mounted on the surface of the support base 1; and a discharge assembly mounted on the surface of the support base 1. Ore and hot air enter the drying cylinder 2 through the feeding assembly and exit through the discharge assembly. The feeding assembly and discharge assembly are mounted on the support base 1 and do not rotate with the drying cylinder 2. The drying cylinder 2 is installed between the feeding assembly and the discharge assembly. The drying cylinder 2 has multiple annularly arranged drying chambers 3 arranged axially upwards. The same amount of ore is separated by multiple drying chambers 3 to prevent ore accumulation. A material control assembly is installed at the opening on the same side of each drying chamber 3 to control the amount of ore entering the drying chamber 3 and prevent ore from accumulating in different areas. The quantity difference is too large. Each drying chamber 3 is equipped with an axially upward flip plate assembly. The flip plate assembly is used to stir and fry the ore in the drying chamber 3, which helps to increase the uniformity of contact between the ore and the hot air. The gear assembly is installed on the discharge assembly and controls the rotation of the flip plate assembly. The gear assembly is linked with the drying cylinder 2. When the drying cylinder 2 rotates, the flip plate assembly will rotate by the gear assembly, which helps to reduce the setting of the power source. The diversion assembly is installed on one side of the drying cylinder 2 and is rotatably connected to the feeding assembly. The diversion assembly can divert the hot air entering the drying cylinder 2, so that each drying chamber 3 is filled with hot air, improving the uniformity of hot air distribution. The power assembly is installed on the surface of the support base 1 and is used to drive the rotation of the drying cylinder 2. The support assembly is installed on the surface of the support base 1 and is used to support the rotation of the drying cylinder 2.

[0048] For further details, please refer to Figures 1 to 5 The feeding assembly includes a feeding sealing cover 4, an air inlet pipe 5, and a ore inlet pipe 6. The feeding sealing cover 4 is fixedly installed on the surface of the support base 1. A second limiting ring 27 is fixedly connected to the surface of the drying cylinder 2. A second annular limiting groove 29 is provided on the surface of the feeding sealing cover 4 to allow the second limiting ring 27 to rotate, so that the drying cylinder 2 and the feeding sealing cover 4 are connected to each other. The feeding sealing cover 4 does not rotate with the drying cylinder 2 when the drying cylinder 2 rotates. An air inlet channel 22 and an ore inlet channel 23 are provided inside the feeding sealing cover 4. 5 is fixedly installed on the surface of the feed sealing cover 4 and is interconnected with the air inlet channel 22. Hot air is introduced from the air inlet pipe 5 and enters the drying cylinder 2 through the air inlet channel 22. The ore inlet pipe 6 is fixedly installed on the surface of the feed sealing cover 4 and is interconnected with the ore inlet channel 23. The ore inlet channel 23 is interconnected with the drying chamber 3. Ore is conveyed from the ore inlet pipe 6 into the drying cylinder 2 and enters the drying chamber 3 through the ore inlet channel 23. The material control component is located at the connection end between the drying chamber 3 and the ore inlet channel 23. The material control component controls the amount of ore entering the drying chamber 3.

[0049] For further details, please refer to Figures 2 to 6 The drying cylinder 2 has a ventilation chamber 26, and a dividing frame 38 is provided between the ventilation chamber 26 and the drying chamber 3. The dividing frame 38 can prevent the ore from moving out of the drying chamber 3, and does not hinder the flow of hot air between the drying chamber 3 and the ventilation chamber 26. The ventilation chamber 26 is interconnected with the air inlet channel 22, so that hot air can enter the drying cylinder 2. The flow distribution component includes a flow distribution plate 7, which is fixedly installed on the side of the drying cylinder 2, so that the flow distribution plate 7 can rotate with the drying cylinder 2 when the drying cylinder 2 rotates. The air inlet channel 22 The inner wall of the container is fixedly connected to a first limiting ring 25. The surface of the diversion plate 7 is provided with a first annular limiting groove 24 for the first limiting ring 25 to rotate, so that the diversion plate 7 and the feed sealing cover 4 are connected to each other and can rotate together with the drying cylinder 2. The surface of the diversion plate 7 is provided with a vent hole 20 for connecting the vent chamber 26. The surface of the diversion plate 7 is provided with a plurality of diversion holes 21 arranged in an annular array, and the diversion holes 21 are used to connect the drying chamber 3. The vent hole 20 and the diversion holes 21 are used to divert hot air to each chamber in the drying cylinder 2.

[0050] For further details, please refer to Figure 2 , Figure 3 , Figure 8 and Figure 9 Multiple connecting pipes 8 arranged in a ring array are fixedly installed on the surface of the distribution plate 7, and the connecting pipes 8 are connected to the distribution holes 21. The connecting pipes 8 are rotatably connected to the flap assembly, and the surface of the flap assembly has multiple air outlets 10. The connecting pipes 8 and the air outlets 10 are interconnected. The flap assembly is connected to the distribution plate 7 through the connecting pipes 8, so that hot air can enter between the flap assembly and be dissipated into the drying chamber 3 from the air outlets 10. This allows the hot air to dissipate outward from the center of the drying chamber 3, which is beneficial for uniform heat dissipation. The flap assembly includes a gas distribution pipe 9 and a guide plate 11. The guide plate 11 is fixedly installed on the surface of the gas distribution pipe 9. The presence of the guide plate 11 on the surface of the gas distribution pipe 9 makes the position of the gas distribution pipe 9 tend to be towards the center of the drying chamber 3. The air distribution pipe 9 is rotatably connected to the connecting pipe 8 at one end, which facilitates the rotation of the air distribution pipe 9. The air outlet 10 is opened on the surface of the air distribution pipe 9. The gear assembly includes a first gear ring 19 and a first transmission gear 12. The number of first transmission gears 12 is the same as that of the air distribution pipes 9, and they are fixed at one end of the air distribution pipes 9 respectively. The end of each air distribution pipe 9 is fixed with a first transmission gear 12. When the drying cylinder 2 rotates, the first transmission gear 12 moves along the inner ring of the first gear ring 19, so that each air distribution pipe 9 will rotate synchronously. This can prevent the situation where different air distribution pipes 9 have different rotation speeds, resulting in different drying efficiencies of the ore in different drying chambers 3. The first gear ring 19 is fixedly installed on the discharge assembly, and the first transmission gear 12 and the first gear ring 19 are meshed.

[0051] For further details, please refer to Figure 2 , Figure 4 and Figure 10 The discharge assembly includes a discharge sealing cover 17, a discharge pipe 18, and a venting pipe 14. The discharge sealing cover 17 is fixedly installed on the surface of the support base 1. A third limiting ring 28 is fixedly connected to the surface of the drying cylinder 2. A third annular limiting groove 30 is provided on the surface of the discharge sealing cover 17 to allow the third limiting ring 28 to rotate, so that the drying cylinder 2 and the discharge sealing cover 17 are interconnected. The discharge sealing cover 17 does not rotate with the drying cylinder 2 when the drying cylinder 2 rotates. A discharge channel 31 is provided inside the discharge sealing cover 17, which is interconnected with the drying chamber 3 and the ventilation chamber 26. The discharge pipe 18... The discharge sealing cover 17 is fixedly installed at the bottom and is connected to the discharge channel 31, so that the ore comes out from the discharge pipe 18. The vent pipe 14 is fixedly installed at the top of the discharge channel 31 and is connected to the discharge channel 31, so that hot air comes out from the vent pipe 14. The bottom of the discharge channel 31 is provided with a protective groove 32. The first gear ring 19 is fixedly installed in the protective groove 32, and the protective groove 32 has an opening for the vent pipe 9 and the first transmission gear 12 to move, which helps to protect the first gear ring 19 and the first transmission gear 12 from being damaged by the ore collision.

[0052] For further details, please refer to Figure 2 , Figure 3 and Figure 7 The material control assembly includes a positioning plate 13, an electric telescopic rod 15, and a telescopic baffle 16. The positioning plate 13 is fixedly installed on the inner wall of the drying chamber 3, and the electric telescopic rod 15 is fixedly installed inside the positioning plate 13. The positioning plate 13 protects the electric telescopic rod 15 and reduces the probability of damage to it. The telescopic end of the electric telescopic rod 15 extends towards the outer ring of the drying cylinder 2, so that when different drying chambers 3 are connected to the ore inlet channel 23, the telescopic baffle 16 always faces downward. The extension of the electric telescopic rod 15 drives the telescopic baffle 16 to move downward. The telescopic end of the electric telescopic rod 15 is fixedly connected to the telescopic baffle 16. By driving the telescopic baffle 16 to move up and down through the electric telescopic rod 15, the size of the opening of the ore inlet channel 23 is changed to control the amount of ore entering.

[0053] For further details, please refer to Figure 1 The power assembly includes a second gear ring 33, a second transmission gear 34, and a motor 35. The motor 35 is fixedly mounted on the surface of the support base 1, and the output shaft of the motor 35 is fixedly connected to the second transmission gear 34. The second gear ring 33 is fixedly sleeved on the surface of the drying cylinder 2, and the second gear ring 33 and the second transmission gear 34 are meshed. When the motor 35 is started, the drying cylinder 2 is rotated through gear transmission.

[0054] For further details, please refer to Figure 1The support assembly includes a support ring 36 and a support wheel 37. The support wheel 37 is fixedly installed on the surface of the support base 1, and the support ring 36 is fixedly sleeved on the surface of the drying cylinder 2. The support ring 36 and the support wheel 37 are slidably connected. The support wheel 37 supports the drying cylinder 2. When the drying cylinder 2 rotates, the support ring 36 and the support wheel 37 rotate relative to each other without affecting the rotation of the drying cylinder 2.

[0055] A drying process based on the aforementioned ore dryer includes the following specific steps:

[0056] A. Start the power unit to make the drying cylinder 2 rotate, and blow hot air into the dryer from the air inlet pipe 5. Use the diversion component to make hot air pass through each chamber of the drying cylinder 2. The hot air is finally dissipated from the air outlet pipe 14.

[0057] B. The ore to be dried is conveyed into the dryer from the ore inlet pipe 6. The material control component is started to control the amount of ore to be dried per unit time. The gear component is used to make each flap component flip over to stir the ore and convey it to the discharge sealing cover 17.

[0058] C. Take out the dry ore from the ore outlet pipe 18.

[0059] Specifically, the ore inlet pipe 6 can be connected to an ore conveying device to convey the ore to be dried into the dryer. The air inlet pipe 5 can be connected to a hot air source to blow hot air into the dryer to dry the ore. The hot air dries the ore. The motor 35 drives the second transmission gear 34 to rotate, the second transmission gear 34 drives the second gear ring 33 to rotate, and the second gear ring 33 drives the drying cylinder 2 to rotate, so that the ore in the drying cylinder 2 is turned over, increasing the contact area with the hot air. The dried ore is discharged from the ore outlet pipe 18. The support roller 37 contacts the support ring 36 to support the drying cylinder 2.

[0060] Multiple drying chambers 3 are arranged in a ring array. With the rotation of the drying cylinder 2, the ore enters from the inlet pipe 6 and passes through the inlet channel 23. When the opening of the drying chamber 3 connects with the opening of the inlet channel 23, the ore falls from the inlet channel 23 into the drying chamber 3. Then the drying cylinder 2 rotates, and the next drying chamber 3 connects with the inlet channel 23, and the ore falls into the next drying chamber 3. In this way, the same amount of ore is divided into multiple portions and dried in the drying cylinder 2, which can prevent a large amount of ore from accumulating and causing uneven drying.

[0061] The ore enters through the inlet pipe 6 and passes through the inlet channel 23. At the connection between the inlet channel 23 and the drying chamber 3, the electric telescopic rod 15 is activated to extend and retract, which can drive the telescopic baffle 16 to move up and down, thereby changing the opening size of the connection between the inlet channel 23 and the drying chamber 3. This controls the amount of ore entering the drying chamber 3. When the ore passes through the bottom of the telescopic baffle 16, it will be flattened by the telescopic baffle 16. This can prevent different ores from entering the drying chamber 3 at different times due to different mass flow rates, which would result in different amounts of ore accumulating in different areas of the drying chamber 3 and cause uneven ore distribution.

[0062] The drying cylinder 2 has a ventilation chamber 26. Hot air enters the air inlet channel 22 from the air inlet pipe 5, and then enters the ventilation chamber 26 from the air inlet channel 22 to dry the ore in the drying chamber 3. The dividing mesh frame 38 between the ventilation chamber 26 and the drying chamber 3 can prevent the ore from moving out of their respective drying chambers 3, and does not hinder the hot air from entering the drying chamber 3. The diverter plate 7 installed at the opening in the air inlet channel 22 that connects to the ventilation chamber 26 can divert the hot air. The hot air flows into the ventilation chamber 26 through the ventilation hole 20, which is the main channel hot air. The hot air flows from the diverter hole 21 to the connecting pipe 8, and then from the connecting pipe 8 to the air distribution pipe 9. Then it flows out from the air outlet 10 on the air distribution pipe 9, passes through the middle of the drying chamber 3, and dries the ore in the middle of the ore, increasing the amount of contact between each ore and the hot air, improving the uniformity of ore drying. Finally, the hot air is discharged from the air diffuser pipe 14.

[0063] When the drying cylinder 2 rotates, the second limiting ring 27 rotates within the second annular limiting groove 29, and the third limiting ring 28 rotates within the third annular limiting groove 30. The rotation of the drying cylinder 2 will cause the diversion plate 7 to rotate together, causing the first limiting ring 25 to rotate within the first annular limiting groove 24. The rotation of the diversion plate 7 will cause the connecting pipe 8, the air distribution pipe 9, and the first transmission gear 12 to move together. The first transmission gear 12 moves along the inner ring of the first gear ring 19. Since the first transmission gear 12 and the first gear ring 19 are meshed, the first transmission gear 12 will rotate when it moves along the inner ring of the first gear ring 19. The rotation of the first transmission gear 12 will cause the air distribution pipe 9 to rotate. The rotation of the air distribution pipe 9 will cause the guide plate 11 to move. The guide plate 11 moves along the inner wall of the drying chamber 3, which can stir up the ore in the drying chamber 3, increase the amount of contact between the ore and the hot air, and make the ore fully dry.

[0064] Multiple guide plates 11 are spirally distributed at equal intervals on the surface of the gas distribution pipe 9, and the guide plates 11 are inclined in the direction of the axis of the gas distribution pipe 9. This allows the ore to slide along the inclined direction of the guide plates 11 when it falls onto the surface of the guide plates 11. This prevents the ore from sticking to the surface of the guide plates 11 when they move along the inner wall of the drying chamber 3, thus failing to achieve the purpose of dispersing the ore and improving the uniformity of ore drying.

[0065] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
