Description

Technical Field

[0001] The utility model belongs to the technical field of belt cleaning, and in particular relates to a belt sticking material cleaning device. Background Art

[0002] Currently, ironmaking operations require the use of belt conveyors to transport sticky materials. After a period of operation, a significant amount of material can remain stuck to the belts. If not promptly cleaned, this can negatively impact subsequent transport, reducing the conveyor's transport capacity and increasing power consumption. However, existing methods for cleaning belts primarily utilize high-pressure water flushing. While this can flush away the sticky material, it also wets the belt surface, causing the material to continue to adhere to the belt surface during subsequent transport, creating a sticky material cycle. This approach is unsatisfactory and needs improvement. Utility Model Content

DETAILED DESCRIPTION

[0018] The present invention is described in further detail below with reference to the accompanying drawings and specific embodiments:

[0019] like Figures 1 to 4 As shown, a belt sticky material cleaning device includes a device body disposed below a belt 1 of a belt conveyor. The device body includes a material frame 2. The top of the material frame 2 is open, and a first hydraulic cylinder 3 is vertically fixedly mounted on the upper left side of the inner bottom, and a second hydraulic cylinder 4 is vertically fixedly mounted on the upper right side of the inner bottom. The piston rod of the first hydraulic cylinder 3 faces upward and is horizontally fixedly connected to a transverse air pipe 5. The left end of the transverse air pipe 5 is connected to the air outlet of an air pump 7 fixed to the inner bottom of the material frame 2 through a hose 6, and the right end is horizontally fixedly connected to a longitudinal air pipe 8. The upper portion of the longitudinal air pipe 8 is fixedly connected to a plurality of first nozzles 9 spaced apart along its length. The tail ends of the first nozzles 9 are arranged upward and tilted toward the right end of the belt 1. The piston rod of the second hydraulic cylinder 4 is upward and fixedly connected to the transmission box 10. A motor 11 is fixedly mounted on the inner bottom of the transmission box 10. The output shaft of the motor 11 is coaxially fixedly connected to a crankshaft 12. The crankshaft 12 is rotatably connected to the side wall of the transmission box 10 and has a plurality of first connecting rod journals 13 and second connecting rod journals 14. The first connecting rod journals 13 and the second connecting rod journals 14 are of different heights and are staggered. A first connecting rod 15 is installed on the first connecting rod journal 13, and a second connecting rod 15 is installed on the second connecting rod journal 14. There is a second connecting rod 16, the top end of the first connecting rod 15 is hinged with a first slide 17, the top end of the second connecting rod 16 is hinged with a second slide 18, the first slide 17 and the second slide 18 are both slidably sleeved with the top of the transmission box 10, and the top end of the first slide 17 extends out of the transmission box 10 and is detachably connected to a first scraper 19, the top end of the second slide 18 extends out of the transmission box 10 and is detachably connected to a second scraper 20, and the top ends of the first scraper 19 and the second scraper 20 can both abut against the lower surface of the belt 1;

[0020] To clean the belt 1, first operate the first hydraulic cylinder 3, extending its piston rod. This moves the transverse air pipe 5 upward until the distance between the first nozzle 9 and the belt 1 is optimal. Next, operate the motor 11, rotating the crankshaft 12 to a certain angle. This, in conjunction with the corresponding connecting rod journals, connecting rods, and slides, raises all first scrapers 19 to their highest position. Next, operate the second hydraulic cylinder 4, extending its piston rod, which moves the entire transmission case 10 upward until the first scrapers 19 contact the belt 1. After that, the belt 1 and the air pump 7 work, and the multiple first scrapers 19 can be used to achieve multiple effective scraping and cleaning processes on the belt 1, and the materials adhered to the belt 1 can be scraped and cleaned into the material frame 2. Then, the air pump 7 provides wind power, and the multiple first nozzles 9 are used to reversely purge the belt 1, and the materials adhered to the belt 1 are blown and cleaned into the material frame 2 again. Under the cooperation, the belt 1 can be cleaned more cleanly and the dryness of the surface of the belt 1 can be ensured. The effect of solving the sticky materials is more ideal and more conducive to subsequent transportation. After a period of use, the motor 11 can be operated to drive the crankshaft 12 to rotate 180 degrees, and the second scraper 20 can be raised until it contacts the belt 1, so that the first scraper 19 is lowered to the lowest position, and the scraping and cleaning is continued by the second scraper 20. The first scraper 19 can be disassembled and replaced as needed through the detachable connection between the corresponding scraper and the corresponding slide. After the second scraper 20 has been used for a period of time, the motor 11 can be operated again to switch, thereby allowing the first scraper 19 and the second scraper 20 to work alternately, which can better ensure the scraping and removing effect. In addition, the configuration of the first hydraulic cylinder 3 and the second hydraulic cylinder 4 can flexibly adjust the distance between the first nozzle 9 and the first scraper 19 or the second scraper 20 and the belt 1, so that the entire device can be flexibly adapted to the actual height of the belt 1, making the overall use more flexible, convenient, and practical. The motor 11 can be a conventional stepping motor with a brake function to achieve the corresponding angle of rotation and position locking after rotation.

[0021] In this embodiment, a guide plate 21 is fixedly provided on the right side of the bottom of the horizontal air pipe 5. The guide plate 21 is tilted downward toward the right side, which can effectively intercept and guide the material blown down by the first nozzle 9, so that it falls into the material frame 2 more smoothly.

[0022] In this embodiment, the lower part of the longitudinal air pipe 8 is fixedly connected to a second nozzle 22, and the tail end of the second nozzle 22 is tilted downward toward the tail end of the guide plate 21, which can effectively purge the guide plate 21 to prevent materials falling onto the guide plate 21 from sticking and accumulating on the guide plate 21.

[0023] In this embodiment, a dovetail-shaped slot 23 is provided on the top of the first slide 17 and the second slide 18, and a power-off holding electromagnet 24 is built into the first slide 17 and the second slide 18 below the slot 23. The bottom ends of the first scraper 19 and the second scraper 20 are fixedly connected with a magnetic dovetail-shaped plug-in block 25, which is adapted to and plugged into the corresponding slot 23, and the plug-in block 25 can be magnetically connected to the corresponding power-off holding electromagnet 24, so that when replacing the first scraper 19 or the second scraper 20, it is only necessary to first turn on the corresponding power-off holding electromagnet 24 to demagnetize it, release the magnetic connection to the corresponding plug-in block 25, and then pull out the plug-in block 25 from the corresponding slot 23, so that the original first scraper 19 or the second scraper 20 can be removed. After obtaining a new first scraper 19 or second scraper 20, the plug 25 on it can be aligned with the corresponding slot 23 and plugged into place. Then, the circuit of the corresponding power-off holding type electromagnet 24 can be disconnected, so that the power-off holding type electromagnet 24 is magnetic when the power is off. The plug 25 is magnetically fixed, and the new first scraper 19 or second scraper 20 is installed and fixed. The installation is stable and does not affect subsequent use. In this way, the first scraper 19 and the second scraper 20 can be flexibly and conveniently disassembled, assembled and replaced, and the quality of the scraping material cleaning can be better guaranteed, making the entire cleaning device more convenient and practical. The power-off holding type electromagnet 24 is a prior art and is suitable for environments where long-term suction is required. Compared with ordinary electromagnets that generate magnetism when powered on and demagnetize when powered off, it has the opposite characteristics. It has the characteristics of demagnetization when powered on and magnetism when powered off, which can reduce electricity usage and is more practical. The plug 25 can be made of existing conventional magnetic metal materials such as iron.

[0024] In this embodiment, the angle between the first nozzle 9 and the belt 1 is 30 degrees to ensure a better blowing effect.

[0025] In this embodiment, a discharge pipe 27 with a discharge valve 26 is connected to the lower part of one side of the material frame 2 for discharging the cleaned materials received by the material frame 2 when needed.

[0026] In this embodiment, legs 28 are fixedly provided at the four corners of the outer bottom of the material frame 2 to support and fix the material frame 2 .

[0027] The lifting plate 30 is slidably sleeved on the corresponding leg 28, and casters 31 are installed on the bottom of the lifting plate 30 away from the corresponding third hydraulic cylinder 29. When the piston rod of the third hydraulic cylinder 29 is in a retracted state, the bottom end of the caster 31 is higher than the bottom of the leg 28, so that in actual use, the entire cleaning device can be switched back and forth between the supporting fixed state and the mobile walking state, which is convenient for transporting the cleaning device or adjusting the position of the cleaning device according to actual needs, making the use of the entire device more flexible and convenient. Specifically, when the device needs to be moved, the third hydraulic cylinder 29 is operated to extend its piston rod, which can drive the lifting plate 30 to move down until the caster 31 is placed on the ground and the leg 28 is lifted up, and the entire cleaning device can be driven to move flexibly through the cooperation of the four sets of casters 31. After moving into position, it is only necessary to operate the third hydraulic cylinder 29 again to retract its piston rod, thereby driving the lifting plate 30 to move upward until the casters 31 are suspended in the air and the legs 28 are placed on the ground, so that the cleaning device can be re-fixed.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
