Description
Technical Field
[0001] This utility model relates to the technical field of port belt conveyor equipment, specifically a cleaning device that can automatically clean frozen coal from the surface of the conveyor belt redirection roller. Background Technology
[0002] Belt conveyors are high-efficiency, continuously operating conveying equipment, widely used in coal unloading ports. The idler rollers are crucial load-bearing and transmission components of the belt conveyor system. Typical conveyor belts are closed loop systems designed for continuous operation; however, this means that a portion of the idler rollers is in constant contact with the coal-carrying surface of the conveyor belt.
[0003] When the coal being transported by the conveyor belt is relatively damp, some wet coal will adhere to the surface of the redirecting drum. When the temperature is above zero degrees Celsius, the adhered wet coal will be thrown off with the operation of the conveyor belt and the redirecting drum, without affecting the operation of the conveyor belt system. However, when the temperature drops below zero degrees Celsius, the wet coal adhering to the surface of the redirecting drum will freeze and gradually accumulate. In winter, the low temperature reduces the elasticity of the conveyor belt. When the frozen coal on the surface of the drum accumulates too much, it will damage the conveyor belt wrapped around the drum. In severe cases, it can cause the entire conveyor belt to tear, resulting in significant economic losses and production stoppage losses.
[0004] Therefore, we propose a cleaning device that can automatically clean frozen coal from the surface of the conveyor belt redirection roller to solve the problems mentioned above. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Example 1: Please refer to Figures 1-3 A cleaning device for automatically cleaning frozen coal on the surface of a deflector roller of a conveyor belt includes a deflector roller body 3 and a cleaning structure 5 disposed on one side of the deflector roller body 3. The cleaning structure 5 is used to clean the surface of the deflector roller body 3. Bearing seats 2 are respectively installed at the front and rear ends of the deflector roller body 3. A support 1 is disposed on one side of the bearing seats 2. The cleaning structure 5 is placed inside the support 1. A heating structure 6 is also disposed inside the support 1. The heating structure 6 is located on one side of the deflector roller body 3. A conveyor belt 4 for conveying coal is disposed on the outer side of the deflector roller body 3.
[0023] The cleaning structure 5 includes a drive shaft 51 and a friction disc 52 disposed on one side of the drive shaft 51. A connecting shaft 54 is disposed on the inner side of the friction disc 52. The connecting shaft 54 is connected to one end of the drive shaft 51. Cleaning blades 55 are evenly distributed on the outer side of the connecting shaft 54. The cleaning blades 55 are used to scrape off the frozen coal on the surface of the redirecting drum body 3.
[0024] The bracket 1 has a base plate 53 on its inner side, and a mounting seat 531 is provided on the base plate 53. The mounting seat 531 is sleeved on the outer side of the drive shaft 51. Fastening bolts 532 are provided on the surface of the mounting seat 531. The fastening bolts 532 are used to fix the mounting seat 531.
[0025] The base plate 53 is a welded steel plate in the shape of an "U". It has mounting holes on its surface. An adjusting bolt 56 is provided on one side of the base plate 53. The adjusting bolt 56 is installed on the side plate of the base plate 53 and presses against the side of the mounting seat 531, which can press the friction disc 52 against the cylinder surface of the redirecting roller body 3.
[0026] Several positioning grooves 541 are evenly distributed on the outer side of the connecting shaft 54. One end of the cleaning blade 55 can be inserted into the positioning groove 541. Screws 542 are evenly distributed on the outer side of the positioning groove 541 to fix the position of the cleaning blade 55, so that the cleaning blade 55 and the connecting shaft 54 are detachably connected and the cleaning blade 55 can be replaced.
[0027] Two sets of base plates 53 are provided, and the two sets of base plates 53 are symmetrically distributed about the center line of the support 1. The base plates 53 are welded to the support 1.
[0028] In this embodiment: the base plate 53 is welded to the inner side of the bracket 1. Then, the drive shaft 51 can be fixed to the base plate 53 using the mounting seat 531 and fastening bolts 532. The adjusting bolts 56 are installed on the side plate of the base plate 53, pressing against the side of the mounting seat 531, which can press the friction disc 52 against the cylinder surface of the redirecting roller body 3. Then, one end of the cleaning blade 55 can be inserted into the positioning groove 541 and fixed with screws 542. Thus, the cleaning blade 55 can be detachably installed on the base plate 53 and pressed against the redirecting roller body 3. The friction disc 52 on the drum body 3 enables relative movement with the redirecting drum body 3. When wet sticky coal is conveyed on the conveyor belt 4 and the wet sticky coal freezes on the surface of the redirecting drum body 3, the cleaning blades 55 that operate relative to the redirecting drum body 3 will cut off the protruding frozen coal to prevent the frozen coal blocks from accumulating too large or too high, thus cleaning the frozen coal. Conversely, when a set of cleaning blades 55 is damaged, the cleaning blades 55 can be removed from the positioning groove 541 for replacement without having to remove the entire cleaning structure 5 for maintenance, effectively reducing costs.
[0029] Example 2: This example is an improvement on Example 1. For details, please refer to [link / reference]. Figure 4 The heating structure 6 includes a heating tube 63 and mounting brackets 62 disposed at both ends of the heating tube 63. A mounting block 61 is disposed at the lower end of the mounting bracket 62. Screws 542 are also disposed on the mounting block 61. The mounting block 61 can be fixed to the bracket 1 by means of the screws 542.
[0030] In this embodiment: the heating tube 63 is placed on one side of the redirecting drum body 3 and inside the conveyor belt 4. The heating structure 6 is then fixed to the bracket 1 using screws 542 and mounting blocks 61. Before cleaning the redirecting drum body 3, the heating tube 63 is turned on so that it can work and generate heat to heat the frozen coal on the redirecting drum body 3, making the frozen coal soft and melt, which is convenient for cleaning. It can also reduce the friction between the cleaning blade 55 and the redirecting drum body 3, thus reducing wear.
[0031] Working principle: The heating pipe 63 is placed on one side of the redirecting drum body 3 and inside the conveyor belt 4. The heating structure 6 is then fixed to the bracket 1 using screws 542 and mounting blocks 61. Before cleaning the redirecting drum body 3, the heating pipe 63 is turned on to generate heat, which softens and melts the frozen coal on the redirecting drum body 3. The drive shaft 51 is fixed to the base plate 53 using the mounting base 531 and fastening bolts 532. Adjusting bolts 56 are installed on the side plate of the base plate 53. On the side of the mounting base 531, the friction disc 52 can be pressed against the cylindrical surface of the redirecting drum body 3, and then one end of the cleaning blade 55 can be inserted into the positioning groove 541 and fixed with screws 542. The cleaning blade 55 can be detachably installed on the base plate 53. The friction disc 52 pressed against the cylindrical surface of the redirecting drum body 3 achieves relative movement with the redirecting drum body 3. When wet sticky coal is conveyed on the conveyor belt 4 and wet sticky coal freezes on the surface of the redirecting drum body 3, the cleaning blade 55, which moves relative to the redirecting drum body 3, will cut off the protruding frozen coal.
