Description

Technical Field

[0001] This utility model relates to the field of belt conveyor technology, and in particular to a belt conveyor with a cleaning and recycling device. Background Technology

[0002] When conveying materials with high moisture content, such as washed coal, on a belt conveyor, some material will always remain on the working surface of the belt. If the residual material enters the belt conveyor rollers, idlers, or the slewing bearings of the belt alignment bracket, it will accelerate the damage to the equipment.

[0003] Currently, the cleaning devices for belt conveyors are limited in function and can typically only clean materials with relatively high dryness levels. If the material is firmly adhered to the belt, conventional brushes are ineffective in removing it. For some stubborn materials, scrapers are usually used to remove them during belt movement. However, because the scrapers are in close contact with the belt, and some materials are severely hardened, the scrapers struggle to remove the material quickly during belt movement, hindering the belt's progress and potentially damaging it. Utility Model Content

[0004] The purpose of this invention is to solve the above-mentioned problems by designing a belt conveyor with a cleaning and recycling device, which solves the problem that existing cleaning devices are unable to clean stubborn materials on the belt.

[0005] To achieve the above objectives, the technical solution of this utility model is a belt conveyor with a cleaning and recycling device, comprising a belt conveyor line and a cleaning mechanism. The cleaning mechanism includes a first cleaning mechanism, a second cleaning mechanism, and a third cleaning mechanism. The first cleaning mechanism, the second cleaning mechanism, and the third cleaning mechanism are arranged below the belt conveyor line and along the belt rotation direction of the belt conveyor line. A return line for receiving the material scraped off the belt is provided below the first cleaning mechanism, the second cleaning mechanism, and the third cleaning mechanism. The first cleaning mechanism includes at least one brush for cleaning the bottom of the belt, the brush extending along the width direction of the belt; The second cleaning mechanism includes a horizontally fixed rotating shaft extending along the width direction of the belt, and a plurality of scraping components rotatably connected to the rotating shaft. The plurality of scraping components are arranged sequentially along the width direction of the belt. The front end of each scraping component has a scraping plate. The scraping plate forms a certain angle with the belt and can contact the bottom of the belt. The center of gravity of the scraping component is away from the scraping plate. The third cleaning mechanism includes a nozzle extending along the width of the belt, the nozzle having a plurality of small holes for spraying water onto the bottom of the belt to clean the bottom of the belt.

[0006] Preferably, the first cleaning mechanism further includes a first fixed frame and a plurality of support plates fixedly mounted on the first fixed frame, each support plate being provided with a brush.

[0007] Preferably, the first cleaning mechanism further includes a first fixed frame, a roller rotatably connected to the first fixed frame, and a motor for driving the roller to rotate. The outer surface of the roller is provided with brushes, and the rotation direction of the roller is the same as the rotation direction of the belt.

[0008] Preferably, the second cleaning mechanism further includes a second fixed frame, the rotating shaft is horizontally fixed on the second fixed frame, and a limit rod is provided on the fixed frame. The limit rod is located above the end of the scraper near the scraper plate or below the end away from the scraper plate.

[0009] Preferably, the scraper includes a rotating plate, the front end of which has a mounting groove, and the scraper is fixedly mounted in the mounting groove by screws.

[0010] Preferably, a counterweight is provided at the end of the rotating plate away from the scraper.

[0011] Preferably, one end of the scraper is bent upward to form a scraping section.

[0012] Preferably, both the rotating plate and the scraper plate have rectangular holes to form a hollow area.

[0013] Preferably, the third cleaning mechanism includes a third fixed frame, the nozzle is fixedly installed on the third fixed frame, and there are multiple nozzles, which are distributed sequentially along the travel direction of the belt.

[0014] Preferably, the material conveying direction of the return line is consistent with the material conveying direction of the belt conveyor.

[0015] Its advantages over existing technologies are: This utility model's belt conveyor uses three cleaning mechanisms to clean materials adhering to the bottom working surface of the belt in a layered manner. During belt movement, the bottom of the belt is first cleaned by a brush, followed by scraping away the material adhering to the belt surface by a scraper. For stubborn clumps adhering to certain localized areas, the scraper will deflect downwards to avoid them, preventing excessive resistance from hindering belt operation and ensuring the normal operation of the belt conveyor. Any remaining stubborn clumps are moistened by water spraying from a nozzle, becoming softer and easily scraped off when the belt passes the location of the scraper again during belt movement. The cleaned material falls onto a return line for recycling. The three cleaning mechanisms can be selectively activated to clean different materials.

[0016] The three cleaning mechanisms in this belt conveyor can effectively remove residual materials on the belt, directly reducing equipment wear, extending service life, reducing maintenance costs, improving operating efficiency, ensuring safe production, improving the working environment, and reducing material loss, among other significant effects.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0020] like Figure 1 , Figure 2 As shown, a preferred embodiment of this utility model proposes a belt conveyor with a cleaning and recycling device, wherein the cleaning and recycling device consists of two parts: a cleaning mechanism and a return line 5. The cleaning mechanism includes three cleaning methods: a first cleaning mechanism 2, a second cleaning mechanism 3, and a third cleaning mechanism 4. The three cleaning mechanisms clean the material on the working surface of the belt 101 in a layered manner.

[0021] The first cleaning mechanism 2, the second cleaning mechanism 3, and the third cleaning mechanism 4 are arranged sequentially along the rotation direction of the belt 101. They respectively use a brush 201 to clean the material at the bottom of the belt 101, a scraper 322 to clean the material at the bottom of the belt 101, and a water spray to clean the bottom of the belt 101.

[0022] The return line 5 is located below the first cleaning mechanism 2, the second cleaning mechanism 3 and the third cleaning mechanism 4. The first cleaning mechanism 2, the second cleaning mechanism 3 and the third cleaning mechanism 4 can be fixedly installed on the return line 5 by connecting plates, or they can be fixedly installed at the bottom of the belt conveyor line 1 by connecting plates, without specific limitations.

[0023] For details, see Figure 3 In this embodiment, the first cleaning mechanism 2 mainly consists of a first fixed frame 21, support plates 22, and brushes 201. The first fixed frame 21 is a frame-shaped structure, and multiple support plates 22 are arranged sequentially and fixed in the hollow area in the middle of the first fixed frame 21. Each support plate 22 is equipped with a brush 201. The brushes 201 are fixed to the support plates 22 with screws and are therefore detachable. The brushes 201 extend along the width of the belt 101, and their length is approximately the same as the width of the belt 101. The brush surface of the brushes 201 faces upwards and is in close contact with the bottom of the belt 101 on the belt conveyor line 1.

[0024] During the movement of the belt 101 of the belt conveyor line 1, the brush 201 will sweep off the material adhering to the bottom working surface of the belt 101, and the swept material will fall onto the return line 5 below.

[0025] See Figure 4 In other embodiments, the first cleaning mechanism 2 may also employ a roller 23 brush. Specifically, the first cleaning mechanism 2 consists of a first fixed frame 21, a roller 23, brushes 201, and a motor 24. The roller 23 is located in the hollow area in the middle of the first fixed frame 21, and the roller 23 is rotatably connected to the first fixed frame 21 via a rotating shaft. Both ends of the rotating shaft are rotatably connected to the first fixed frame 21 via bearings. The motor 24 is mounted on the outside of the first fixed frame 21, and the output end of the motor 24 is connected to one end of the rotating shaft via a coupling. Brushes 201 are distributed on the outer surface of the roller 23, and the axial length of the roller 23 is approximately the same as the width of the belt 101. The brushes 201 on the outer side of the roller 23 are in close contact with the working surface at the bottom of the belt 101.

[0026] During the movement of the belt 101 of the belt conveyor line 1, the motor 24 drives the roller 23 to rotate in the same direction as the belt 101. Therefore, the brush 201 on the outside of the roller 23 will move relative to the belt 101, cleaning the material on the bottom working surface of the belt 101 and achieving a better cleaning effect.

[0027] like Figure 5 As shown, in this embodiment, the second cleaning mechanism 3 mainly consists of a second fixed frame 31, a rotating shaft, and a scraper 32. The second fixed frame 31 comprises two fixed plates and two connecting rods. The two connecting rods are located at both ends of the fixed plates, connecting the two fixed plates together to form a frame structure. The rotating shaft is fixedly installed in the hollow area in the middle of the second fixed frame 31. Both ends of the rotating shaft are fixedly connected to the two fixed plates respectively.

[0028] Multiple scraper components 32 are arranged in sequence along the axial direction of the rotating shaft and are rotatably connected to the rotating shaft.

[0029] See Figure 6 The scraper component 32 consists of a rotating plate 321, a counterweight 323, and a scraper plate 322. The rotating plate 321 has a rotating hole 3211 located near the end of the scraper plate 322, thus ensuring that the center of gravity of the scraper component 32 is close to the end of the counterweight 323. A bearing is installed within the rotating hole 3211, and the rotating plate 321 is rotatably connected to the rotating shaft via the bearing.

[0030] A mounting groove is provided at the upper end of the rotating plate 321. One end of the scraper plate 322 is fixedly installed in the mounting groove with screws, and the other end is bent upwards at a certain arc to form the scraper part 3221. Since the scraper plate 322 will wear down after long-term use, it is detachably mounted on the rotating plate 321 to reduce maintenance costs. In the later maintenance, only the scraper plate 322 needs to be replaced, and it is not necessary to replace the entire scraper part 32.

[0031] The counterweight 323 is installed at the end of the rotating plate 321 away from the scraper plate 322. The counterweight 323 is generally fixed to the rotating plate 321 with screws, and is therefore removable to adjust the center of gravity of the scraper 32. In its natural state, the end of the scraper 322 where the scraper plate 322 is located will tilt upwards, and the scraping part 3221 of the scraper plate 322 will be in close contact with the working surface of the bottom of the belt 101. The end where the counterweight 323 is located will drop downwards, so that the scraper 32 remains tilted.

[0032] The material adhering to the working surface of the belt 101 may clump in some areas due to varying moisture content, and this clumping is uneven. Therefore, during the movement of the belt 101, if a severely hardened clumping appears on the path of a scraper 32 that cannot be completely scraped off, the end of the scraper 32 containing the scraper blade 322 will deflect downwards to avoid the clumping and prevent it from being forcibly scraped off. In areas where there is no severe clumping, the scraper blade 322 of the scraper 32 will continue to remain in contact with the bottom working surface of the belt 101.

[0033] Therefore, when cleaning the belt 101, the multiple scraper components 32 of the second cleaning mechanism 3 will move like piano keys. When encountering severely hardened clumps, they will deflect downwards to avoid them, preventing the belt 101 from being blocked due to high resistance, and ensuring the normal operation of the belt 101 conveyor line 1.

[0034] like Figure 5 As shown, in order to limit the upward deflection of the scraper 322, a limiting rod 33 is also provided on the second fixed frame 31. The limiting rod 33 is located above the end of the rotating plate 321 near the scraper 322. That is, under the action of the counterweight 323, the scraper 322 tilts upward. Under the restriction of the limiting rod 33, the scraping part 3221 of the scraper 322 just contacts the bottom working surface of the belt 101 and forms a certain angle with the working surface, preventing the scraper 32 from becoming vertical and lifting the belt 101, thus failing to scrape the material.

[0035] In other embodiments, the limiting rod 33 can also be set below the end of the rotating plate 321 near the counterweight 323, which can also limit the deflection angle of the scraper 32.

[0036] See Figure 6 Both the rotating plate 321 and the scraper plate 322 have rectangular holes to form a hollow area, so that the material falling onto the scraper 32 can fall through the rectangular holes onto the return line 5 below.

[0037] When the second cleaning mechanism 3 is not in use, the counterweight 323 can be removed, and the rotating plate 321 and the scraper 322 can be kept horizontal. The scraper 322 will disengage from the belt 101.

[0038] like Figure 7As shown, the third cleaning mechanism 4 mainly consists of a third fixed frame 41 and nozzles 42. Multiple nozzles 42 can be provided, distributed sequentially along the travel direction of the belt 101. Generally, at least one nozzle 42 is provided. The nozzles 42 are fixedly mounted on the third fixed frame 41 and extend along the width direction of the belt 101. Several small holes are provided on the surface of the nozzles 42, distributed along the width direction of the belt 101. A water source is connected to the nozzles 42, and the water jet from the nozzles 42 flows towards the working surface at the bottom of the belt 101.

[0039] The water flow will refresh the working surface at the bottom of the belt 101, washing away the materials with high moisture content that are adhering to the belt 101. At the same time, it will moisten the severely solidified clumps, making them soft so that when the moistened clumps reach the location of the second cleaning mechanism 3 again during the operation of the belt conveyor, they can be easily scraped off by the scraper 32.

[0040] The three cleaning mechanisms work together to clean the material on the working surface at the bottom of belt 101.

[0041] The cleaned material will fall onto the return line 5, which is also conveyed by the belt 101. The conveying direction of the return line 5 is the same as that of the belt conveyor 1. Finally, the cleaned material will be conveyed by the return line 5 to the position conveyed by the belt conveyor 1 or to other positions.

[0042] The three cleaning mechanisms can be selectively activated. For loose, non-clumping materials adhering to the belt surface, the first cleaning mechanism 2 can clean them effectively. For materials that are prone to clumping, the second cleaning mechanism 3, or a combination of the second and third cleaning mechanisms 4, can be selected depending on the hardness of the clumps.

[0043] The above technical solution only embodies the preferred technical solution of this utility model. Any changes that may be made by those skilled in the art to certain parts of it embody the principle of this utility model and fall within the protection scope of this utility model.
