Description

Technical Field

[0001] This utility model relates to the field of belt cleaning technology, and more specifically, to a furnace mouth conveyor belt cleaning device. Background Technology

[0002] In the production process of the metallurgical industry, belt conveyors, as the core equipment for material transportation, have long faced the challenges of complex working conditions such as high temperature, high dust, and material adhesion. Especially in the furnace mouth area of ​​pyrometallurgical furnaces, molten material or dust particles can easily adhere to the belt surface. If not cleaned in time, it can lead to belt misalignment and accelerated wear, or even equipment failure or production interruption, seriously affecting operational efficiency and safety.

[0003] Traditional cleaning methods primarily rely on manual shoveling, requiring workers to frequently enter the high-temperature, dusty furnace roof area. This is not only time-consuming and labor-intensive but also poses significant safety hazards. Furthermore, because manual cleaning is mostly limited to the lower part of the conveyor belt, some adhering material is directly scattered to the ground or equipment gaps during belt operation due to gravity, resulting in material waste. The scattered residue requires additional manpower for secondary cleaning, further exacerbating labor intensity and resource consumption, making it difficult to meet the continuous and automated production demands of modern smelting. Utility Model Content

[0004] The purpose of this invention is to provide a furnace mouth conveyor belt cleaning device, which solves the problem of inconvenient cleaning of traditional conveyor belts.

The belt conveyor is driven by a driver to move towards the furnace mouth so that the collection plate abuts against the outer wall of the furnace mouth and rotates, thereby guiding the material cleaned by the scraper into the furnace mouth.

[0006] Furthermore, the aggregate plate includes a guard plate, a guide plate, and an action plate connected in sequence. The guard plate and the guide plate are arranged inside the aggregate bin, and the edge of the guard plate and the connection between the guard plate and the guide plate abut against the inner wall of the aggregate bin. The action plate extends out of the aggregate bin, and a rotating shaft connected to the aggregate bin is provided at the connection between the guide plate and the action plate.

[0007] Furthermore, the upper surfaces of both the guard plate and the guide plate are provided with guide grooves that are recessed towards the center line.

[0008] Furthermore, the angle between the guard plate and the guide plate is obtuse, and the angle between the guide plate and the action plate is acute.

[0009] Furthermore, the scrapers are arranged at an angle towards the furnace opening.

[0010] Furthermore, a roller brush is installed at the rear end of the scraper along the belt running direction in the material collection bin.

[0011] Furthermore, the bottom of the collection bin is equipped with a buffer block that contacts the collection plate.

[0012] Furthermore, the scraper is detachably connected to the collection bin via a slot opened in the side wall of the collection bin.

[0013] This utility model has at least the following advantages and beneficial effects: by integrating the collection bin, scraper and collection plate below the discharge end of the belt conveyor, and utilizing the rotation of the collection plate against the outer wall of the furnace opening, a seamless connection between material cleaning and diversion is achieved, reducing manual intervention and lowering safety risks.

[0019] The specific implementation method is described below with reference to the accompanying drawings.

[0020] Example

[0021] like Figs. 1 to 4As shown in this embodiment, a furnace opening conveyor belt cleaning device is disclosed for cleaning the belt 11 on the belt conveyor 1. It includes a collection bin 2 located below the discharge end of the belt conveyor 1. The collection bin 2 is equipped with a scraper 3 that contacts the lower edge of the belt 11. A collection plate 4 is rotatably connected to the bottom of the collection bin 2. A driver drives the belt conveyor 1 towards the furnace opening 5, causing the collection plate 4 to rotate and abut against the outer wall of the furnace opening 5, thus guiding the material cleaned by the scraper 3 into the furnace opening 5. Specifically, the collection bin 2 is connected to the support of the belt conveyor 1 by welding or by bolts to the ear plates on both sides. The scraper 3 directly contacts the lower edge of the belt 11, removing material adhering to the belt 11. The cleaned material falls onto the collection plate 4 of the collection bin 2. It should be noted that when the belt conveyor 1 is completely away from the furnace opening 5, the collecting plate 4 is not pressed against the furnace opening 5 and falls onto the bottom plate of the collecting bin 2. The motor is started, driving the belt 11 to run, which enables self-cleaning of the belt 11. At this time, the material cleaned off the belt 11 is temporarily stored in the collecting bin 2 on the collecting plate 4. When the driver moves the belt conveyor 1, causing the collecting plate 4 to rotate and press against the outer wall of the furnace opening 5, the material temporarily stored in the collecting bin 2 is poured into the furnace, avoiding material waste. Simultaneously, the belt 11 can be cleaned while conveying material, and the cleaned material is directly guided into the furnace. This achieves seamless integration of material cleaning and flow guidance, reducing manual intervention and lowering safety risks.

[0022] Furthermore, in a specific implementation, the aforementioned collecting plate 4 provided in this embodiment of the present invention includes a protective plate 41, a guide plate 42, and an action plate 43 connected in sequence. The protective plate 41 and the guide plate 42 are arranged inside the collecting bin 2, and the edge of the protective plate 41 and the connection between the protective plate 41 and the guide plate 42 abut against the inner wall of the collecting bin 2. The action plate 43 extends outward from the collecting bin 2, and a rotating shaft 44 connected to the collecting bin 2 is provided at the connection between the guide plate 42 and the action plate 43. Specifically, the collecting plate 4 has a three-fold structure. Both sides of the collecting plate 4 are fitted with the inner wall of the collecting bin 2 with a gap, and the edge of the protective plate 41 abuts against the inner wall of the collecting bin 2, forming a closed space to prevent material leakage in non-discharge mode. Among them, the protective plate 41 is used to prevent the cleaning material from falling into the gap between the collecting bin 2 and the collecting plate 4. The guide plate 42 is used to guide the material flow. In the natural state, it guides the material to move towards the protective plate 41; after the collecting plate 4 abuts and rotates, it guides the material to move towards the furnace opening 5. The action plate 43 plays a linkage triggering role. When the material is continuously conveyed into the furnace, the action plate 43 always abuts against the furnace opening 5 to form an inclined material guiding channel, so as to realize the directional discharge of the material into the furnace.

[0023] Furthermore, in specific implementations, the upper surfaces of the aforementioned guard plate 41 and guide plate 42 provided in this embodiment of the present invention are both provided with guide grooves that are recessed towards the centerline. Specifically, the guide grooves can be V-shaped, utilizing gravity to concentrate the material flow path, guiding the material towards the centerline, avoiding dead corners of accumulation, and reducing sidewall adhesion. It should be noted that the belt conveyor 1 is usually equipped with inclined side plates for centering material collection on both sides, so the material usually adheres to the middle of the belt 11. Therefore, the cleaned-up material mostly falls into the middle of the collecting plate 4. Combined with the setting of the guide grooves, the probability of material entering the gap between the collecting plate 4 and the collecting bin 2 can be further reduced. In addition, the surface of the guide grooves can be coated with a tungsten carbide coating to enhance wear resistance and extend service life.

[0024] Furthermore, in specific implementations, the included angle between the guard plate 41 and the guide plate 42 provided in this utility model embodiment is an obtuse angle, and the included angle between the guide plate 42 and the action plate 43 is an acute angle. The obtuse angle between the guard plate 41 and the guide plate 42 expands the material storage space; the acute angle between the guide plate 42 and the action plate 43 forms a linkage force-applying arm.

[0025] Furthermore, in a specific implementation, the scraper 3 provided in this embodiment of the invention is arranged at an angle towards the furnace opening 5. The synergistic effect of the belt 11's movement direction and the scraper 3's angle enhances scraping force and reduces material residue. Simultaneously, the inclined design reduces the vertical pressure between the scraper 3 and the belt 11, preventing excessive wear and extending the belt 11's lifespan.

[0026] Furthermore, in a specific implementation, a roller brush 6 is provided at the rear end of the scraper 3 along the running direction of the belt 11 in the above-mentioned material collection bin 2 provided in this embodiment of the utility model. The roller brush 6 is located behind the scraper 3 and can remove fine particles or dust that are not treated by the scraper 3, achieving multi-stage cleaning. The brush is made of high-temperature resistant nylon filaments, which adapt to the surface as the belt 11 rotates, avoiding damage from hard friction.

[0027] Furthermore, in a specific implementation, a buffer block 7 is provided at the bottom of the collection bin 2 provided in this embodiment of the present invention to contact the collection plate 4. The buffer block 7 is made of polyurethane or rubber, which effectively alleviates the impact force when the collection plate 4 closes, and reduces noise and structural fatigue.

[0028] Furthermore, in a specific implementation, the scraper 3 provided in this embodiment of the present invention is detachably connected to the collection bin 2 via a slot 20 opened on the side wall of the collection bin 2. By fixing the scraper 3 through the slot 20, worn parts can be replaced without disassembling the entire structure, reducing downtime.
