Description

Technical Field

[0001] The utility model relates to the technical field of ferroalloy production, in particular to an automatic cleaning and packaging system for ferrosilicon crushing. Background Art

[0002] Ferrosilicon crushing is a common method in the ferroalloy industry. It mainly consists of a feeding platform, a jaw crusher, a large-angle belt, a circular vibrating screen, an electromagnetic vibrating feeder, a packaging system, a dust removal system and an electronic control system. Ferrosilicon will generate a large amount of ferrosilicon dust in the crushing, screening and packaging links. After being processed by the dust removal system, a large amount of ferrosilicon dust will still float around the equipment, seriously endangering the health of the operators. In the subsequent packaging process of the crushing and screening links, a large amount of dust such as silicon powder, iron powder and iron oxide will be diffused in the air. Although the operators are wearing dust masks, it will still cause certain harm to the body. After the operators inhale these dusts for a long time, they are very likely to develop respiratory diseases. Therefore, further optimizing the automated cleaning and packaging process of ferrosilicon crushing and screening is of great significance to improving the production efficiency of ferrosilicon crushing and screening and improving the production environment.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] A cache silo level display 11 is provided at the front end cache silo 6 of the ferrosilicon crushing and screening body 39, a crusher stall detection sensor 12 is provided on the flywheel side of the crusher 2 of the ferrosilicon crushing and screening body 39, a large-angle belt operation detection sensor 13 is provided at the frame of the large-angle belt 3 of the ferrosilicon crushing and screening body 39, a return belt operation detection sensor 14 and a screen blockage detection sensor 15 are provided on the side of the return belt 4 of the ferrosilicon crushing and screening body 39, a circular vibrating screen 5 is provided with a circular vibrating screen operation status detection sensor 16, and a rear end cache silo level sensor 17 is provided on the side wall of the rear end cache silo 6 of the ferrosilicon crushing and screening body 39.

[0024] The crusher stall detection sensor 12, the high-angle belt operation detection sensor 13, the return belt operation detection sensor 14, the screen blockage detection sensor 15, the circular vibrating screen operation status detection sensor 16 and the rear-end buffer silo level sensor 17 are all connected to the crushing and screening body controller 33.

[0025] A track 38 is fixedly provided at the bottom of the packaging ton bag 9 , and the trolleys 18 are all slidably arranged on the track 38 .

[0026] A trolley weighing sensor 19 is provided at the bottom of the trolley 18, and a trolley return acceleration detection sensor 20 and a trolley return deceleration detection sensor 21 are provided at symmetrical positions on the long side of one side of the track 38, and a trolley loading acceleration detection sensor 25 and a trolley loading deceleration detection sensor 26 are provided at symmetrical positions on the long side of the other side of the track 38, and the trolley weighing sensor 19, the trolley return acceleration detection sensor 20, the trolley return deceleration detection sensor 21, the trolley loading acceleration detection sensor 25 and the trolley loading deceleration detection sensor 26 are all connected to the trolley on-board controller 29.

[0027] A first trolley parking detection point 22 , a second trolley parking detection point 24 , a third trolley parking detection point 27 and a fourth trolley parking detection point 28 are symmetrically provided on the short sides of the track 38 .

[0028] The trolley 18 is provided with an anti-collision detection sensor 23 , and the trolley onboard controller 29 is also connected to a trolley driving actuator 32 .

[0029] The sealing cover 10 is an independently supported steel structure, that is, the side walls are filled with colored steel tiles to close the screening and packaging links. At the same time, a hole is opened on the top and connected to the workshop dust removal system through a pipe to collect the dust in the sealing cover 10. Incisions and canvas curtains are made in the middle of the large-angle belt 3, the middle of the return belt 4, and the intersection of the track 38 and the sealing cover 10. The dust is collected centrally by the workshop dust removal system, thereby preventing the crushed ferrosilicon dust from floating in the working environment.

[0030] In specific applications of the present invention, the crushing and screening body sensor group 37 includes a crusher stall detection sensor 12, a high-angle belt operation detection sensor 13, a return belt operation detection sensor 14, a screen blockage detection sensor 15, a circular vibrating screen operation status detection sensor 16, and a rear-end cache silo material level sensor 17 to monitor the operation status of all equipment in the crushing and screening body in real time, and transmit the corresponding signal to the crushing and screening body controller 33. After data processing by the controller, the real-time status is displayed on the crushing and screening body host computer touch screen 34. One end of the return belt 4 is connected to the discharge pipe corresponding to the upper screen of the circular vibrating screen 5, and the other end is connected to the upper feeding port of the crusher 2. One end of the high-angle belt 3 is connected to the discharge port below the crusher 2, and the other end is connected to the entrance of the circular vibrating screen 5. The circular vibrating screen 5 is composed of three sizes of screens with diameters of φ50mm, φ10mm and φ3mm from top to bottom, and four sizes of finished materials are formed through screening. Then press the one-touch start button on the crushing and screening body controller 33 to start the automatic operation program. First, start the jaw crusher 2. When the jaw crusher 2 reaches the normal speed, delay for a period of time before starting the circular vibrating screen 5. When the vibration of the circular vibrating screen 5 reaches a stable state, delay and start the large-angle belt 3 and the return belt 4. At this time, according to the display of the buffer silo material level display 11, start operating the feeding platform 1 to feed the jaw crusher 2 and start the ferrosilicon crushing operation. The ferrosilicon blocks with an outer size greater than 50mm in the upper screen pass through the return material. Pipe 6.3 diverts the material to return conveyor belt 4, returning it to crusher 2 for re-crushing. Ferrosilicon blocks with dimensions of 10-50mm and 3-10mm are diverted to buffer silo 6 for storage via crushing pipe 6.1. Powder blocks smaller than 3mm are diverted via powder pipe 6.2 to powder bags 9.1 for individual packaging. Because the amount of powder is small compared to the amount of finished ferrosilicon blocks, it is typically collected by wrapping. When powder bags 9.1 are full, manual valve 9.2 above them is closed, and powder bags 9.1 can be removed and replaced. Meanwhile, an electromagnetic vibrating feeder 7 is attached to the underside of buffer silo 6 via a spring and turnbuckle bolts. The vibrations of the electromagnetic vibrating feeder 7 cause the ferrosilicon blocks to fall into lower silo 8, where they are then placed into bulk bags 9 for packaging. When the buffer silo material level display 11 shows a high level, the feeding platform 1 stops moving. When the circular vibrating screen 5 is operating normally, the screen blockage detection sensor 15 can indirectly judge the blockage of the circular vibrating screen 5 by detecting the number of ferrosilicon blocks on the return belt 4, without having to go up to the circular vibrating screen 5 for inspection, which provides convenience for maintenance personnel to inspect; the rear-end buffer silo material level sensor 17 monitors the material level height of the buffer silo 6 in real time. When it reaches the set height, it promptly warns the front-end feeding platform 1 and stops the feeding operation to avoid the risk of overflow of the buffer silo 6.

[0031] After the crushing and screening system is operating normally, the rail trolley 18 of the rear-end packaging link runs clockwise to the bottom of the unloading bin 8 to prepare for receiving materials. The rail trolley on-board controller 29 collects the weight data of the rail trolley weighing sensor 19 and transmits the real-time weight data remotely and wirelessly to the crushing and screening body controller 33. After analysis and processing, the crushing and screening body controller 33 outputs a control signal and acts on the electromagnetic vibrating feeder 7 under the buffer bin 6 to make it unload materials quickly and evenly to achieve the set packaging weight. The weight of each packaged ton bag 9 is set by the crushing and screening body upper computer touch screen 34. After the rail trolley 18 detects that the weight reaches the set value, the upper electromagnetic vibrating feeder 7 stops unloading, and the rail trolley 18 starts to move clockwise along the circular track 38. Each rail trolley 18 is independent of each other and is controlled by the crushing and screening body respectively. The device 33 performs wireless remote communication. Taking the rail trolley 18 at position 3# in the figure as an example, when the weight detected by the rail trolley 18 reaches the set value, the electromagnetic vibrating feeder 7 above stops unloading, and the rail trolley 18 starts to move slowly clockwise along the circular track 38. When encountering the rail trolley 18 at position 4#, it is detected by the anti-collision detection sensor 23 and brakes to wait; when no obstacle is detected in front during the movement, it moves at a normal slow speed; when the rail trolley 18 detects the rail trolley return acceleration detection sensor 20 during the movement, it starts to move at a higher speed; when the rail trolley 18 detects the rail trolley return deceleration detection sensor 21 during the movement, it starts to move slowly to the rail trolley second trolley stop detection point 24. If there is no position at the rail trolley second trolley stop detection point 24, it stops at the nearest rail trolley first trolley stop detection point 22. After the packaging ton bags 9 on the rail trolley 18 are manually moved and loaded onto the rail trolley at the first trolley stop detection point 22 and the second trolley stop detection point 24 and new packaging ton bags 9 are placed, the rail trolley 18 continues to move clockwise with the packaging ton bags 9. When it reaches the rail trolley loading acceleration detection sensor 25, it starts to move at a higher speed. When it reaches the rail trolley loading deceleration detection sensor 26, it moves slowly and finally stops at the rail trolley third trolley stop detection point 27 or the rail trolley fourth trolley stop detection point 28 to start a new round of loading. The entire screening and packaging process is carried out in the sealing cover 10, isolating the high noise and high dust environment. The rail trolley 18 automatically transports the packaging ton bags 9 back and forth, which greatly reduces the physical harm of noise and dust to the operator and effectively achieves the purpose of clean packaging. Therefore, the system has good practicality.
