Description

Technical Field

[0001] The invention relates to the technical field of automatic drying of ore particles, in particular to an automatic drying machine for ore particles. Background Art

[0002] The drying of ore particles plays an important role in multiple links and processes. Dry ore particles have better fluidity during crushing, grinding, screening and other processing processes, and are not easy to clog the equipment, thereby improving the operating efficiency and production capacity of the equipment. At the same time, dry ore is also easy to store and transport. Wet ore particles contain moisture, which is easy to form lumps and blockages in the equipment, causing equipment failure and shutdown. In addition, these moisture still requires additional energy to evaporate during the processing process, thereby increasing energy consumption in the production process.

[0003] In the prior art, wet ore particles are generally put into a drum as a whole for continuous stirring, and the wet ore particles are dried in combination with hot drying and air drying. However, the traditional method of drying wet ore particles has the following defects: 1. The size of ore particles generally varies. During the hot drying and air drying process, the time required for the full drying of large ore particles is generally longer than that required for small ore particles. When small ore particles are simultaneously hot dried with large ore particles, the actual drying time of small ore particles will exceed the required time, resulting in low overall drying efficiency and energy waste during the processing process; 2. The surface of wet ore is generally attached with water droplets and larger impurities. During the hot drying and air drying process, the water droplets attached to the surface of the ore particles will increase the energy and time consumed by the drying process, thereby reducing the efficiency of the overall drying process, and then increasing the cost of the overall processing. In addition, larger impurities generally cannot be discharged with the water vapor, resulting in poor uniformity of the overall drying of the ore particles and poor purity after drying.

[0044] See also Figure 6 , Figure 8 and Fig. 9 The shaking and air-drying mechanism 3 includes a shaking frame 31, an air-drying component 32 and a second vibration component 33; the operating frame 1 is provided with a shaking frame 31, the air-drying component 32 is provided above the shaking frame 31, and the lower side of the end of the air-drying component 32 close to the center of the operating frame 1 is provided with a second vibration component 33; the shaking and air-drying mechanism 3 also includes a collecting hopper 34, a first closing component 35 and a sewage hopper 36; the collecting hopper 34 is fixedly provided at the upper end of the operating frame 1, the lower end of the collecting hopper 34 is provided with a first closing component 35, the outer surface of the collecting hopper 34 is fixedly connected to the shaking frame 31, and a sewage hopper 36 for discharging large particles of impurities is fixedly provided on the outer side of the shaking frame 31 below the air-drying component 32.

[0045] See also Figure 6 and Figure 8The air-drying component 32 includes a vibrating hopper 321, a fine screen 322 and a second rotating wheel 323; a vibrating hopper 321 is elastically slidably arranged above the shaking frame 31, a fine screen 322 for screening ore particles and large particles of impurities is fixedly arranged at the bottom of the vibrating hopper 321, and a second rotating wheel 323 is rotatably arranged on both sides of the front and rear ends of the vibrating hopper 321 close to the center of the operating frame 1.

[0046] See also Figure 6 and Figure 7 The second vibration component 33 includes a second rotating seat 331, a second connecting shaft 332 and a second cam 333; the second rotating seat 331 fixed on the upper surface of the shaking frame 31 is symmetrically arranged on the front and rear sides of the inner end of the vibration hopper 321, and a second connecting shaft 332 is rotatably arranged between the second rotating seats 331, and second cams 333 that cooperate with the second rotating wheel 323 for transmission are fixedly arranged at both ends of the second connecting shaft 332.

[0047] See also Fig. 9 The first closing component 35 includes a first closing plate 351 and a first driven shaft 352; the lower end of the collecting hopper 34 is symmetrically rotatably provided with a first closing plate 351 rotatably connected to the front and rear surfaces of the operating frame 1, and the front surface of the first closing plate 351 is fixedly provided with a first driven shaft 352.

[0048] When the balancing hopper 221 screens the wet ore particles under the indirect drive of the driving mechanism 6, the driving mechanism 6 can synchronously drive the second connecting shaft 332 and the second cam 333 to rotate, and the second cam 333 pushes the second rotating wheel 323 to make the vibrating hopper 321 move up and down, and at the same time, the springs on both sides of the vibrating hopper 321 can drive the whole vibrating hopper 321 to shake up and down quickly. When two groups of wet ore particles of different sizes fall into the corresponding vibrating hopper 321 respectively from the first lower hopper 25 and the second lower hopper 26 under the screening of the balancing hopper 221 and the coarse screen 222, the vibrating hopper 321 can screen the wet ore particles by shaking up and down. The wet ore particles are shaken and air-dried to shake off the water droplets attached to their surface. At the same time, the larger impurities on the surface of the ore particles are also shaken off and sieved through the fine screen 322 and finally discharged from the sewage hopper 36. This method of shaking and air-drying the wet ore particles can not only reduce the time consumed by the hot drying mechanism 4 to dry the wet ore particles, but also improve the efficiency of the overall drying process. At the same time, it saves the energy required to evaporate the water droplets on the surface of the wet ore particles, reduces the cost of the overall drying process, and avoids the problem that larger impurities cannot be discharged through water vapor, thereby improving the uniformity of the overall drying of the ore particles and the purity after drying.

[0049] When the two groups of ore particles of different sizes are all shaken and wind-dried, they will fall into the corresponding collecting hopper 34. At this time, through the cooperation of the driving mechanism 6 and the opening and closing mechanism 5, the two groups of ore particles of different sizes can all enter the corresponding hot drying mechanism 4 for hot drying processing at one time. This operation method can ensure that all ore particles in each group can be hot-dried synchronously, avoiding the problem of different drying time between different ore particles due to the ore particles entering the hot drying mechanism 4 one after another, thereby ensuring the uniformity of the overall drying processing of the ore particles.

[0050] See also Figure 1 and Fig.11 The hot drying mechanism 4 includes a mixing drum 41 and a mixing component 42; the mixing drum 41 is fixedly provided at the lower end of the operating frame 1, and the mixing component 42 is provided in the mixing drum 41; the hot drying mechanism 4 also includes a feeding hopper 43, a hot air blower 44 and a second closing component 45; the feeding hopper 43 is fixedly provided on the upper surface of the mixing drum 41, the hot air blower 44 is fixedly provided on the rear surface of the mixing drum 41, and the second closing component 45 is provided on the lower side of the mixing drum 41.

[0051] See also Fig.11 The stirring assembly 42 includes a stirring shaft 421 and a stirring plate 422 . The stirring shaft 421 is rotatably disposed in the stirring drum 41 , and the stirring plates 422 are evenly and fixedly disposed around the stirring shaft 421 .

[0052] See also Fig.11 and Fig.12 The second closing component 45 includes a second closing plate 451, a slide groove 452 and a second driven shaft 453; the second closing plate 451 is symmetrically slidably arranged on the lower side of the mixing drum 41, and the front and rear surfaces of the second closing plate 451 are symmetrically provided with slide grooves 452 that slide in cooperation with the front and rear surfaces of the operating frame 1, and the front surface of the second closing plate 451 is fixedly provided with a second driven shaft 453.

[0053] When two groups of ore particles of different sizes enter the corresponding mixing drum 41 from the collecting hopper 34 respectively, the hot air blower 44 can be started to heat and dry the ore particles in the mixing drum 41, and at the same time, the driving mechanism 6 drives the stirring shaft 421 and the stirring plate 422 to synchronously stir the ore particles, thereby improving the uniformity of the drying of the ore particles.

[0054] By cooperating with the opening and closing mechanism 5 through the driving mechanism 6, the closing time of the second closing component 45 at the lower side of the mixing drum 41 for hot drying large-particle ore on the left side can be longer than that of the mixing drum 41 for hot drying small-particle ore on the right side, so that the hot drying time of large-particle ore is longer. Under the premise of ensuring the drying quality and uniformity of two groups of ore particles of different sizes, the actual drying time of small-particle ore is reduced, the time and energy consumed by the overall hot drying are reduced, the overall processing efficiency is improved, and the energy distribution during the drying process is optimized, thereby reducing the processing cost.

[0055] While controlling the processing time of two groups of ore particles of different sizes, the driving mechanism 6 can synchronously control the stirring frequency of the stirring shaft 421 and the stirring plate 422, so that the stirring frequency of the stirring plate 422 corresponding to the large-particle ore is higher, thereby further ensuring the quality and uniformity of the thermal drying of the large-particle ore.

[0061] When the first closing component 35 and the second closing component 45 are to be opened and closed, the driven pulley 5214 and the fourth pulley 5213 are rotated by the driving mechanism 6, and the fourth pulley 5213 cooperates with the third pulley 5212 to enable the second driving member 5217 to drive the second linkage frame 5221 and the second opening and closing frame 5223 to move upward, and the second opening and closing frame 5223 can gradually drive the second driven shaft 453 to move inward through the second pressing groove 5224 on the surface, thereby driving the second closing plate 4 51 gradually closes inwardly, and at the same time, the second synchronous wheel 5215 rotating with the third pulley 5212 can drive the first synchronous wheel 5114 and the second pulley 5113 to rotate synchronously through belt transmission. The second pulley 5113 can cooperate with the first pulley 5112 to enable the first driving member 5116 to drive the first linkage frame 5121 and the first opening and closing frame 5123 to move upward. The first opening and closing frame 5123 can gradually drive the first driven shaft 352 to rotate outward through the first pressing groove 5124 on the surface. The first closing plate 351 is driven to open gradually outwards. This operation mode can realize the synchronous up and down movement of the first opening and closing frame 5123 and the second opening and closing frame 5223. Since the first pressing groove 5124 is an L-shaped inclined groove and the second pressing groove 5224 is an inverted L-shaped inclined groove, when the first opening and closing frame 5123 and the second opening and closing frame 5223 move upward synchronously, the second closing plate 451 can be closed first and the first closing plate 351 can be opened later. When the first closing plate 351 is moved downward, the first closing plate 351 can be closed first and the second closing plate 451 can be opened later. This operation mode can ensure that when the lower end of the collecting hopper 34 is opened to discharge materials, the lower side of the mixing drum 41 is in a closed state, so that the ore particles can stably fall into the mixing drum 41 for heat drying. At the same time, it can ensure that when the lower side of the mixing drum 41 is opened to discharge materials, the lower end of the collecting hopper 34 is in a closed state, so that the wet ore particles to be processed in the collecting hopper 34 will not fall into the mixing drum 41 and cannot be fully heat dried.

[0063] See also Figure 1 and Fig.14 The transmission assembly 62 includes a transmission pulley 621 and a transmission gear 622; a transmission pulley 621 is rotatably provided on the front side of the driving frame 61, and the transmission pulley 621 cooperates with the driven pulley 5214 through a belt for transmission, and a transmission gear 622 is fixedly provided on the rear side of the transmission pulley 621 through a rod.

[0064] See also Fig.14 , the first driving assembly 63 includes a first connecting rod 631, a first half gear 632 and a large matching pulley 633; ​​a first connecting rod 631 is rotatably arranged between the left sides of the front and rear driving frames 61, and the front end of the first connecting rod 631 is fixedly provided with a first half gear 632 that cooperates with the left transmission gear 622 for transmission, and the rear end of the first connecting rod 631 is fixedly provided with a large matching pulley 633; ​​the second driving assembly 64 includes a second connecting rod 641, a second half gear 642, a driven gear 643 and a small matching pulley 644; a second connecting rod 641 is rotatably arranged between the right sides of the front and rear driving frames 61, and the front end of the second connecting rod 641 is fixedly provided with a second half gear 642 that cooperates with the right transmission gear 622 for transmission, and the rear end of the second connecting rod 641 is fixedly provided with a driven gear 643 that cooperates with the driving gear 66 for transmission and a small matching pulley 644 that is driven by a belt with the large matching pulley 633.

[0065] When it is necessary to control the heat drying time of two groups of ore particles of different sizes, the driving motor 65 is started to rotate the driving gear 66, and the driving gear 66 drives the driven gear 643, the second connecting rod 641 and the small matching pulley 644 to rotate, and the small matching pulley 644 drives the large matching pulley 633 and the first connecting rod 631 to rotate through the belt transmission. Since the diameter of the large matching pulley 633 is larger than the diameter of the small matching pulley 644, the rotation speed of the first connecting rod 631 is smaller than that of the second connecting rod 641, so that the first connecting rod 631 is rotated at a speed lower than that of the second connecting rod 641. The rotation speed of the half gear 632 is smaller than that of the second half gear 642. When the first half gear 632 and the second half gear 642 respectively intermittently drive the corresponding transmission gear 622 and the transmission pulley 621 to rotate, the rotation speed of the transmission pulley 621 corresponding to the first half gear 632 is also smaller than that of the transmission pulley 621 corresponding to the second half gear 642. The transmission pulley 621 can drive the driven pulley 5214 to rotate through belt transmission, thereby controlling the opening and closing of the lower end of the collecting hopper 34 and the lower side of the mixing drum 41.

[0066] By presetting the initial positions of the first half gear 632 and the second half gear 642, the drive pulleys 621 corresponding to the first half gear 632 and the second half gear 642 can control the first closing plates 351 at the lower ends of the two collecting hoppers 34 to open synchronously for unloading during the initial unloading. At this time, the lower side of the mixing drum 41 is in a closed state. Since the rotation speed of the drive pulley 621 corresponding to the first half gear 632 on the left side is relatively slow, when the small-particle ore in the right-side mixing drum 41 completes the drying process and is unloaded under the drive of the second opening and closing frame 5223 on the right side, the second closing plate 451 on the lower side of the left-side mixing drum 41 is still in a closed state, so that the large-particle ore in the left-side mixing drum 41 can continue to be hot-dried, thereby extending the hot-drying time of the large-particle ore, ensuring the uniformity of the drying of the ore particles while optimizing the energy consumption distribution during the drying process.

[0067] See also Figure 1 , Figure 4 and Figure 5 The linkage assembly 68 includes a first linkage part 681, a second linkage part 682 and a third linkage part 683; the first linkage part 681 is arranged at the rear end of the right stirring shaft 421, the second linkage part 682 is arranged at the rear end of the left stirring shaft 421, and the third linkage part 683 is transmitted in cooperation with the second linkage part 682 through a belt.

[0068] See also Figure 4 The first linkage part 681 includes a speed-increasing linkage wheel 6811 and a first linkage wheel 6812; the speed-increasing linkage wheel 6811 is fixedly connected to the rear end of the right stirring shaft 421 through a rod, and the rear side of the speed-increasing linkage wheel 6811 is fixedly provided with a first linkage wheel 6812 through a rod and driven by a belt with the driving pulley 67.

[0069] See also Figure 5 The second linkage part 682 includes a second linkage wheel 6821 and a third linkage wheel 6822; the second linkage wheel 6821 is fixedly connected to the rear end of the left stirring shaft 421 through a rod, the second linkage wheel 6821 is transmitted through a belt in cooperation with the speed-increasing linkage wheel 6811, and the rear side of the second linkage wheel 6821 is fixedly provided with a third linkage wheel 6822 through a rod.

[0070] When the driving pulley 67 drives the first interlocking wheel 6812 to rotate through belt transmission, the right stirring shaft 421 rotates accordingly and drives the corresponding stirring plate 422 to stir the small-particle ore in the right stirring drum 41. At the same time, the speed-increasing interlocking wheel 6811 drives the second interlocking wheel 6821 and the left stirring shaft 421 to rotate through belt transmission. Since the diameter of the speed-increasing interlocking wheel 6811 is larger than that of the second interlocking wheel 6821, the rotation speed of the second interlocking wheel 6821 and the left stirring shaft 421 is greater than the rotation speed of the right stirring shaft 421, so that the left stirring shaft 421 and the stirring plate 422 have a higher stirring frequency for large-particle ore, thereby ensuring the quality and uniformity of hot drying of large-particle ore.

[0071] See also Figure 1 , Figure 2 and Figure 6 The third linkage part 683 includes a fourth linkage wheel 6831, a fifth linkage wheel 6832, a sixth linkage wheel 6833, a seventh linkage wheel 6834 and an eighth linkage wheel 6835; the fourth linkage wheel 6831 is fixedly arranged at the rear end of the left second connecting shaft 332 through a rod, and the fourth linkage wheel 6831 cooperates with the third linkage wheel 6822 through a belt for transmission, the fifth linkage wheel 6832 is fixedly arranged at the front end of the left second connecting shaft 332 through a rod, the sixth linkage wheel 6833 is fixedly arranged at the front end of the right second connecting shaft 332 through a rod, and the sixth linkage wheel 6833 cooperates with the fifth linkage wheel 6832 through a belt for transmission, the seventh linkage wheel 6834 is fixedly arranged at the rear end of the right second connecting shaft 332 through a rod, and the eighth linkage wheel 6835 is fixedly arranged at the rear end of the first connecting shaft 232, and the eighth linkage wheel 6835 cooperates with the seventh linkage wheel 6834 through a belt for transmission.

[0072] When the equalizing hopper 221 and the vibrating hopper 321 are to be synchronously driven to vibrate up and down by the driving motor 65, the driving motor 65 is started to make the driving pulley 67 indirectly drive the second interlocking wheel 6821 and the third interlocking wheel 6822 to rotate, and the third interlocking wheel 6822 drives the fourth interlocking wheel 6831 and the second connecting shaft 332 on the left to rotate through belt transmission, thereby driving the left vibrating hopper 321, and the fifth interlocking wheel 6832 that rotates synchronously with the left second connecting shaft 332 drives the sixth interlocking wheel 6833 and the second connecting shaft 332 on the right to rotate through belt transmission, thereby driving the right vibrating hopper 321, and the seventh interlocking wheel 6834 that rotates synchronously with the right second connecting shaft 332 drives the eighth interlocking wheel 6835 and the first connecting shaft 232 to rotate through belt transmission, thereby synchronously driving the vibrating hopper 321 and the equalizing hopper 221. This driving method can realize the overall drying process through a single drive, thereby ensuring the unity and continuity of the overall drying process.
