Technical Field
[0001] This utility model relates to the technical field of aluminum ash ball mill screening equipment, specifically designed as an aluminum ash screening machine and aluminum ash ball mill screening equipment that do not require frequent shutdowns. Background Technology
[0002] Aluminum ash ball milling and screening equipment typically includes a ball mill, a conveyor, and a screening machine. The ball mill is responsible for grinding the aluminum ash, while the conveyor feeds the ground aluminum ash into the screening machine for sieving. The screening machine usually has multiple aluminum ash discharge sections to discharge aluminum ash of different particle sizes after sieving. For example, it may have three discharge sections (front, middle, and rear) to discharge extremely fine, relatively fine, and relatively coarse aluminum ash, respectively. Normally, workers install bags at each discharge port to collect the aluminum ash. When subsequent processing steps are not strict about the particle size of the aluminum ash, the fine aluminum ash discharged from the extremely fine and relatively fine discharge sections can be mixed and used. Whenever a bag is full of aluminum ash, workers must use a forklift to remove it and install a new bag at the same discharge section. To avoid leakage of aluminum ash from the bagless discharge section during bag replacement, which would result in resource waste, workers must stop the screening machine each time a bag is replaced. However, in actual operation, the filling rate of each bag is different and the filling time is not uniform. This means that after the staff has finished replacing one bag and restarted the screening machine, the other bags may be filled up very quickly, causing the staff to frequently stop the machine to replace the bags. Utility Model Content
[0003] The technical problem this invention aims to solve is to provide an aluminum ash screening machine that does not require frequent shutdowns. When subsequent processing steps do not have strict requirements on the particle size of the aluminum ash, workers can change the bags used to collect fine aluminum ash without stopping the screening operation. This invention also provides an aluminum ash ball mill screening device that includes the aforementioned aluminum ash screening machine.
[0004] To solve the above-mentioned technical problems, the present invention provides an aluminum ash screening machine that does not require frequent shutdowns. It is equipped with a fine aluminum ash discharge section for discharging fine aluminum ash and a coarse aluminum ash discharge section for discharging coarse aluminum ash. There are multiple fine aluminum ash discharge sections arranged in parallel. Below the multiple fine aluminum ash discharge sections, there is a strip-shaped receiving plate in the front-to-back direction to receive the fine aluminum ash. The rear end of the receiving plate extends backward to the rear of the last fine aluminum ash discharge section. A conveying mechanism is installed on the receiving plate to send the fine aluminum ash backward to the rear end of the receiving plate. A fine aluminum ash collection bag is hung at the rear end of the receiving plate to collect the fine aluminum ash sent to the rear end of the receiving plate.
[0005] Furthermore, the receiving plate is a "U" shaped plate that is low in the middle and high on the left and right sides.
[0006] Furthermore, a guide is provided at the rear end of the receiving tray. The guide is aligned with the fine aluminum ash collection bag to guide the fine aluminum ash from the rear end of the receiving tray to the fine aluminum ash collection bag. A spare fine aluminum ash collection bag is also hung at the rear end of the receiving tray. The guide is an exposed movable part that can be switched to be aligned with the spare fine aluminum ash collection bag to guide the fine aluminum ash to the spare fine aluminum ash collection bag.
[0007] Furthermore, the receiving tray has a drop port at the rear end for fine aluminum ash to fall down. The guide is specifically a guide tube, which is rotatably installed at the rear end of the receiving tray. Its inlet end is connected to the drop port, and its outlet end is aligned with the fine aluminum ash collection bag, guiding the fine aluminum ash falling down from the drop port to the fine aluminum ash collection bag. The guide can be rotated to be aligned with a spare fine aluminum ash collection bag, thereby guiding the fine aluminum ash to the spare fine aluminum ash collection bag.
[0008] Furthermore, a mounting frame is provided, on which the receiving plate is mounted. The bottom of the mounting frame is equipped with casters, which can move the receiving plate away from below the fine aluminum ash discharge section.
[0009] Furthermore, the conveying mechanism includes a spiral conveying rod in the forward and backward direction and a drive motor that drives the spiral conveying rod.
[0010] The present invention relates to an aluminum ash ball milling and screening equipment, comprising a ball mill, a conveyor, and a screening machine. The ball mill grinds the aluminum ash, and the conveyor sends the ball-milled aluminum ash to the screening machine for screening, as described above.
[0011] Normally, the receiving tray receives fine aluminum ash from multiple fine aluminum ash discharge sections. The conveying mechanism then transports this fine aluminum ash to the rear end of the receiving tray, where it is collected by a fine aluminum ash collection bag. When the collection bag is full, workers can replace it without stopping the screening machine; they only need to stop the conveying mechanism. Because the rear end of the receiving tray extends beyond the rearmost fine aluminum ash discharge section, replacing the collection bag at the rear end does not affect the tray's ability to collect fine aluminum ash. In other words, while workers are replacing the collection bag, the receiving tray continues to receive fine aluminum ash from the discharge sections, and this ash is not wasted. Workers simply restart the conveying mechanism to transport the remaining fine aluminum ash to the rear end of the receiving tray for collection by the new collection bag. Since the screening machine does not need to be stopped when the staff changes the fine aluminum ash collection bag, this aluminum ash screening machine does not need to be stopped frequently.

[0022] The present invention will be further described in detail below with reference to specific embodiments.
[0023] First embodiment.
[0024] See aluminum ash ball mill screening equipment Figure 1The system includes a ball mill 100 at the rear, a conveyor 200 in the middle, and a screening machine 300 at the front. Workers pour aluminum ash into the feed inlet 101 at the rear of the ball mill 100, where it is ball-milled. The milled aluminum ash is then discharged through the discharge outlet 102 at the front of the ball mill 100 to the conveyor 200. The conveyor 200 then transports the milled aluminum ash forward to the screening machine 300, where it undergoes multi-stage screening. The screening machine 300 body 1 is existing technology. It is equipped with four aluminum ash discharge sections 11, 12, 13, and 14 arranged in a front-to-back pattern to discharge aluminum ash of different particle sizes. Specifically: ultrafine aluminum ash is discharged from the first discharge section 11, which is closest to the conveyor 200; fine aluminum ash is discharged from the second discharge section 12; standard fine aluminum ash is discharged from the third discharge section 13; and coarse aluminum ash is discharged from the fourth discharge section 14, which is furthest from the conveyor 200. The first, second, and third discharge sections 11, 12, and 13 are all fine aluminum ash discharge sections 10, and the fourth discharge section 14 is a coarse aluminum ash discharge section 20. Since subsequent processing steps do not have strict requirements on the particle size of aluminum ash, the aluminum ash discharged from the three fine aluminum ash discharge sections 10 can be mixed and used. Since the ball mill 100 and the conveyor 200 are existing technologies, they will not be described in detail below. The screening machine 300 will be described in detail.
[0025] Screening machine 300 Figure 2 A bag-hanging rod 3 is provided at the coarse aluminum ash discharge section 20. A coarse aluminum ash collection bag 41 with its opening 410 facing upwards is hung on the bag-hanging rod 3 to collect the coarse aluminum ash discharged from the coarse aluminum ash discharge section 20. A first tray 51 is placed under the coarse aluminum ash collection bag 41, and the first tray 51 has fork slots 511 for forklifts to lift it. See Figure 3 and Figure 4 Below the three fine aluminum ash discharge sections 10, there is a mounting frame 61. A strip-shaped receiving tray 62, oriented front-to-back, is mounted on the mounting frame 61. The receiving tray 62 is a "U"-shaped tray, lower in the middle and higher on the left and right sides. It is located below the three fine aluminum ash discharge sections 10 and receives the fine aluminum ash discharged from them. A spiral conveyor rod 63, oriented front-to-back, is mounted on the receiving tray 62. The front end 611 of the mounting frame 61 extends forward beyond the receiving tray 62 and is equipped with a drive motor 64, which drives the spiral conveyor rod 63. The rear end 612 of the mounting frame 61 extends backward beyond the rearmost fine aluminum ash discharge section 10 (i.e., the first discharge section 11) and is equipped with a bag hanger 65. A fine aluminum ash collection bag 42 is hung on the bag hanger 65. A second pallet 52 is placed under the fine aluminum ash collection bag 42, and a fork slot 521 is formed on the second pallet 52 for forklift lifting. See Figure 5 The receiving plate 62 extends beyond the rearmost fine aluminum ash discharge section 10, located at the rear end 612 of the mounting frame 61 and has a drop opening 623. The fine aluminum ash collection bag 42 has its opening 420 facing upward and aligned with the drop opening 623.
[0026] See Figure 3 and Figure 5 Normally, the receiving tray 62 receives the fine aluminum ash discharged from the three fine aluminum ash discharge sections 10. Because the receiving tray 62 is a U-shaped tray with a lower center and higher left and right sides, the aluminum ash falling onto the receiving tray 62 tends to concentrate in the center and is less likely to fall from the left and right sides. The drive motor 64 and the screw conveyor 63 form a conveying mechanism. When the operator starts the drive motor 64, it drives the screw conveyor 63 to send the fine aluminum ash to the rear end 622 of the receiving tray 62. The fine aluminum ash sent to the rear end 622 of the receiving tray 62 falls through the drop outlet 623 into the fine aluminum ash collection bag 42, which collects the fine aluminum ash. Once the fine aluminum ash collection bag 42 is full, the operator replaces it, as follows.
[0027] See Figure 3 and Figure 4 The operator does not need to stop the screening machine 300 body 1 from screening; they only need to stop the drive motor 64 from driving the screw conveyor 63, thus stopping the conveying mechanism from conveying fine aluminum ash. The operator separates the fine aluminum ash collection bag 42 from the bag hanger 65, then uses a forklift to lift the second pallet 52 and the fine aluminum ash collection bag 42 and move them to another location. A new fine aluminum ash collection bag 42 is then taken out and hung on the bag hanger 65, and a new second pallet 52 is placed under the new fine aluminum ash collection bag 42. Because the rear end 622 of the receiving tray 62 extends beyond the rearmost fine aluminum ash discharge section 10, replacing the fine aluminum ash collection bag 42 located at the rear end 622 of the receiving tray 62 will not affect the receiving tray 62's ability to collect fine aluminum ash. In other words, during the replacement of the fine aluminum ash collection bag 42, the receiving tray 62 can continue to collect the fine aluminum ash discharged from the fine aluminum ash discharge section 10, and this fine aluminum ash will not be wasted. The staff can restart the drive motor 64 to send the fine aluminum ash on the receiving plate to the rear end 622 of the receiving plate 62, where it will be collected by the new fine aluminum ash collection bag 42.
[0028] See Figure 2 and Figure 3 When staff replace the fine aluminum ash collection bag 42, it is not necessary to stop the screening machine 300 body 1 from screening. The screening machine 300 body 1 only needs to be stopped when replacing the coarse aluminum ash collection bag 41. Therefore, the aluminum ash screening machine 300 does not need to be stopped frequently. The specific operation for replacing the coarse aluminum ash collection bag 41 is as follows: First, stop the screening machine 300 body 1 from screening. Then, separate the coarse aluminum ash collection bag 41 from the hanging rod 3. Use a forklift to lift the first pallet 51 and the coarse aluminum ash collection bag 41 and move them to another place. Take out the new coarse aluminum ash collection bag 41 and hang it on the hanging rod 3. Take out the new first pallet 51 and place it under the new coarse aluminum ash collection bag 41.
[0029] See Figure 3 and Figure 6 Hanging rods 3 are also provided at the three fine aluminum ash discharge sections 10, and locking casters 610 are installed at the bottom of the mounting frame 61. The casters 610 are normally locked. If the subsequent processing steps have strict requirements on the particle size of the aluminum ash, resulting in the aluminum ash discharged from the three fine aluminum ash discharge sections 10 not being able to be mixed, the operator's procedure is as follows.
[0030] First, stop the screening operation of the screening machine 300 body 1. Then, release the locking state of the universal wheel 610 and push the mounting frame 61, allowing the mounting frame 61 to move the receiving plate 62, the screw conveyor rod 63, and the drive motor 64 together from under the three fine aluminum ash discharge sections 10. Take out three new fine aluminum ash collection bags 42 and hang them on the bag hanging rods 3 of each fine aluminum ash discharge section 10. Place a second tray 52 under each fine aluminum ash collection bag 42 for support. Figure 6 As shown, this allows for the collection of fine aluminum ash of different particle sizes discharged from the three fine aluminum ash discharge sections 10 using three new fine aluminum ash collection bags 42, thereby achieving classified use.
[0031] Second embodiment.
[0032] The second embodiment is largely the same as the first embodiment, except that: see Figure 7 and Figure 8 In the second embodiment, the screening machine 300 has two bag hanging racks 71 and 72 installed at the rear end 612 of the mounting frame 61. Both bag hanging racks 71 and 72 are located at the rear end 622 of the receiving plate 62. Each bag hanging rack 71 and 72 hangs a fine aluminum ash collection bag 42, and a second tray 52 is placed under each fine aluminum ash collection bag 42. An installation tube 67 extends downwards from the rear end 622 of the receiving plate 62 at the drop outlet 623, and a guide tube 68 is rotatably installed on the installation tube 67. Both the installation tube 67 and the guide tube 68 are made of PVC plastic pipes and have a certain degree of elasticity. Figure 9 A retaining ring 670 protrudes from the outer wall of the lower end 672 of the mounting tube 67 towards the outer periphery. An annular groove 680 is formed on the inner wall of the upper end 681 of the guide tube 68. The retaining ring 670 engages with the groove 680, allowing the guide tube 68 to rotate and mount on the mounting tube 67 in this manner. See [link / reference] Figure 8 The upper end 681 of the guide tube 68 serves as the inlet end and the lower end 682 serves as the outlet end. The upper end 671 of the mounting tube 67 is connected to the drop outlet 623, and the lower end 672 is connected to the upper end 681 of the guide tube 68. The lower end 682 of the guide tube 68 is aligned with the opening 420 of the fine aluminum ash collection bag 421 on the left.
[0033] See Figure 4 , Figure 7 and Figure 8Normally, the receiving tray 62 receives the fine aluminum ash discharged from the three fine aluminum ash discharge sections 10. The drive motor 64 and the screw conveyor 63 form a conveying mechanism. When the operator starts the drive motor 64, it drives the screw conveyor 63 to send the fine aluminum ash to the rear end 622 of the receiving tray 62. The fine aluminum ash sent to the rear end 622 of the receiving tray 62 falls from the drop outlet 623 into the guide tube 68. The guide tube 68, as an exposed guide, guides the fine aluminum ash to the left-hand fine aluminum ash collection bag 421. The left-hand fine aluminum ash collection bag 421 collects the fine aluminum ash. In this state, the right-hand fine aluminum ash collection bag 422 serves as a spare fine aluminum ash collection bag. After the left-hand fine aluminum ash collection bag 421 is full, the operator replaces it. The specific operation is as follows.
[0034] See Figure 4 , Figure 7 and Figure 8 The operator does not need to stop the screening machine 300 body 1 from screening. They only need to stop the drive motor 64 from driving the screw conveyor 63, thus stopping the conveying mechanism from conveying fine aluminum ash. Then, they can rotate the guide tube 68 to switch the guide tube 68 to its lower end 682 aligned with the right-hand fine aluminum ash collection bag 422, bag opening 420. Figure 10 As shown, during this process, the receiving tray 62 continues to receive the fine aluminum ash discharged from the three fine aluminum ash discharge sections 10, and this fine aluminum ash is not wasted. The operator restarts the drive motor 64 to send the fine aluminum ash on the receiving tray 62 to the rear end 622 of the receiving tray 62, and then the guide tube 68 guides the fine aluminum ash to the fine aluminum ash collection bag 422 on the right, where it is collected. Then the operator separates the fine aluminum ash collection bag 421 on the left from the hanging bag rack 71, uses a forklift to lift the second pallet 52 on the left and the fine aluminum ash collection bag 421 on the left and moves them to another location. A new fine aluminum ash collection bag 42 is taken out and hung on the hanging bag rack 71 on the left, and a new second pallet 52 is taken out and placed under the fine aluminum ash collection bag 42.
[0035] The above description is merely an embodiment of the present invention and does not limit the scope of patent protection. Any non-substantial changes or substitutions made by those skilled in the art based on the present invention will still fall within the scope of patent protection.
