Description

Technical Field

[0001] This utility model relates to the field of boiler feeding technology, and in particular to a hopper conveying device for an anti-clogging boiler. Background Technology

[0002] Boilers fueled by wood chips have many advantages, such as being low-carbon and environmentally friendly: wood chips are a renewable energy source with low carbon emissions, no sulfur emissions, and low nitrogen oxide emissions when burned, meeting environmental protection requirements and helping to reduce greenhouse gas emissions and air pollution; and having low fuel costs: wood chip fuel costs are generally lower than natural gas and biomass pellets, are more economical than coal, and can utilize local cheap wood resources, which has a positive impact on the local economy, etc.

[0003] When wood chips are used as boiler fuel, existing technologies often employ a combination of a hopper and a conveyor belt to feed the boiler. Specifically, wood chips in the hopper are continuously transported into the boiler via a conveyor belt at the bottom. This feeding method has certain drawbacks. For example, the conveyor belt can easily cause blockages by transporting large amounts of wood chips into the boiler at once, and the wood chips are prone to stagnation within the hopper due to friction from the side walls, affecting the uniformity and continuity of feeding. Therefore, this invention proposes an anti-clogging boiler hopper conveying device to address the shortcomings of existing technologies. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide an anti-clogging boiler hopper conveying device. This device comprises a rotating first anti-clogging roller installed on one side of the outlet end of the feeding conveyor belt, and a rotating second anti-clogging roller installed inside the feeding hopper near the first anti-clogging roller. The first and second anti-clogging rollers can prevent a large quantity of wood chips from being transported into the boiler at once via the feeding conveyor belt, thus preventing boiler feeding blockage. Furthermore, when the first and second anti-clogging rollers rotate, they can disperse the wood chips using multiple sets of dispersing teeth.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A hopper conveying device for an anti-clogging boiler includes a feeding platform, a feeding hopper, and a feeding conveyor belt. The feeding hopper is mounted on the top of the feeding platform via a bracket, and the feeding conveyor belt is located below the feeding hopper. The feeding conveyor belt is mounted to the feeding platform. A mounting frame is symmetrically arranged on one side of the outlet end of the feeding conveyor belt. A first anti-clogging roller is rotatably arranged between the two mounting frames. A second anti-clogging roller is located on the upper inner side of one end of the feeding hopper near the first anti-clogging roller. Connecting seats are provided on the inner walls of the feeding hopper at both ends of the second anti-clogging roller. The two ends of the second anti-clogging roller are rotatably connected to the two connecting seats respectively. Dispersing tooth groups are provided on the outer walls of both the first and second anti-clogging rollers. Multiple dispersing tooth groups are provided, each consisting of multiple dispersing tooth bars.

[0007] A further improvement is that the height of the first anti-clogging roller is lower than the height of the second anti-clogging roller.

[0008] A further improvement is that: both the first and second anti-clogging rollers are equipped with synchronous pulleys on their shaft ends, and a belt connects the two synchronous pulleys; a motor mount is provided on the top of the feeding platform to install a drive motor, and the output end of the drive motor is connected to the shaft end of the second anti-clogging roller.

[0009] A further improvement is that the feeding hopper includes a first side plate, a second side plate, and an end plate. The first side plate and the second side plate are both inclined and symmetrical to each other. An end plate is provided at one end of the first side plate and the second side plate on the side away from the first anti-clogging roller.

[0010] A further improvement is that: the feeding conveyor belt is equipped with auxiliary rollers, and there are multiple sets of auxiliary rollers. Both ends of the multiple sets of auxiliary rollers are equipped with supports that are installed on the feeding platform, and the auxiliary rollers are rotatably connected to the supports.

[0011] A further improvement is that the bracket is provided with fixing holes, and both the first side plate and the second side plate can be detachably installed to the fixing holes by fixing bolts.

[0012] The beneficial effects of this utility model are as follows: This utility model has a rotating first anti-blocking roller on one side of the outlet end of the feeding conveyor belt, and a rotating second anti-blocking roller inside the feeding hopper near the first anti-blocking roller. The first and second anti-blocking rollers can prevent a large amount of wood chips in the feeding hopper from being transported into the boiler at one time through the feeding conveyor belt, causing boiler feeding blockage. When the first and second anti-blocking rollers rotate, they can disperse the wood chips through the dispersing teeth of multiple sets of dispersing teeth, avoiding the wood chips from clogging in the feeding hopper, improving the uniformity of feeding, and achieving stable feeding without jamming.

[0017] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0018] Example 1

[0019] according to Figure 1-3 As shown in the figure, this embodiment proposes an anti-clogging boiler hopper conveying device, including a feeding platform 1, a feeding hopper 2, and a feeding conveyor belt 3. The feeding hopper 2 is installed above the feeding platform 1 via a bracket 15, and the feeding conveyor belt 3 is provided below the feeding hopper 2. The feeding conveyor belt 3 is installed with the feeding platform 1. A mounting frame 4 is symmetrically provided on one side of the outlet end of the feeding conveyor belt 3. A first anti-clogging roller 5 is rotatably provided between the two mounting frames 4. A second anti-clogging roller 6 is provided on the upper inside of one end of the feeding hopper 2 near the first anti-clogging roller 5. Connecting seats 7 are provided on the inner walls of the feeding hopper 2 at both ends of the second anti-clogging roller 6. The two ends of the second anti-clogging roller 6 are rotatably connected to the two connecting seats 7 respectively. Dispersing tooth groups are provided on the outer walls of both the first anti-clogging roller 5 and the second anti-clogging roller 6. Multiple dispersing tooth groups are provided, and each dispersing tooth group is composed of multiple dispersing tooth rods 8.

[0020] When the anti-clogging boiler hopper conveying device of this utility model is used for feeding wood chips, the inside of the feeding hopper 2 is used to store wood chip fuel. Then, the feeding conveyor belt 3 located at the bottom of the feeding hopper 2 will drive the wood chip fuel to feed, so as to evenly transport the wood chip fuel into the boiler. In this process, in order to prevent a large amount of wood chip fuel from entering the boiler at one time, the first anti-clogging roller 5 and the second anti-clogging roller 6 can block the wood chip fuel inside the feeding hopper 2 to prevent blockage caused by a large amount of material discharged at one time. When the first anti-clogging roller 5 and the second anti-clogging roller 6 rotate, they can continuously disperse the wood chip fuel through the dispersing toothed rod 8, so that the wood chip fuel enters the boiler in a loose state.

[0021] The first anti-clogging roller 5 is set at a lower height than the second anti-clogging roller 6. This arrangement allows the first and second anti-clogging rollers 5 and 6 to block material discharge at two different heights, preventing blockages caused by a large volume of material being discharged at once.

[0022] Both the first anti-clogging roller 5 and the second anti-clogging roller 6 have synchronous pulleys 9 on their shaft ends, and a belt 10 connects the two synchronous pulleys 9. A motor mount on the top of the feeding platform 1 houses a drive motor 11, and the output end of the drive motor 11 is connected to the shaft end of the second anti-clogging roller 6. When the drive motor 11 is started, the first anti-clogging roller 5 and the second anti-clogging roller 6 rotate synchronously under the transmission of the two synchronous pulleys 9 and the belt 10, thereby continuously breaking up the wood chip fuel using the dispersing toothed rod 8.

[0023] The feeding hopper 2 includes a first side plate 201, a second side plate 202, and an end plate 203. The first side plate 201 and the second side plate 202 are both inclined and symmetrical to each other. The end plate 203 is provided at one end of the first side plate 201 and the second side plate 202 on the side away from the first anti-clogging roller 5. This arrangement of the feeding hopper 2 can effectively ensure that the wood chip fuel is discharged from the outlet end of the feeding conveyor belt 3.

[0024] The bracket 15 is provided with fixing holes, and the first side plate 201 and the second side plate 202 are detachably installed to the fixing holes by fixing bolts 14.

[0025] Example 2

[0026] according to Figure 1-3As shown in the figure, this embodiment proposes an anti-clogging boiler hopper conveying device, including a feeding platform 1, a feeding hopper 2, and a feeding conveyor belt 3. The feeding hopper 2 is installed above the feeding platform 1 via a bracket 15, and the feeding conveyor belt 3 is provided below the feeding hopper 2. The feeding conveyor belt 3 is installed with the feeding platform 1. A mounting frame 4 is symmetrically provided on one side of the outlet end of the feeding conveyor belt 3. A first anti-clogging roller 5 is rotatably provided between the two mounting frames 4. A second anti-clogging roller 6 is provided on the upper inside of one end of the feeding hopper 2 near the first anti-clogging roller 5. Connecting seats 7 are provided on the inner walls of the feeding hopper 2 at both ends of the second anti-clogging roller 6. The two ends of the second anti-clogging roller 6 are rotatably connected to the two connecting seats 7 respectively. Dispersing tooth groups are provided on the outer walls of both the first anti-clogging roller 5 and the second anti-clogging roller 6. Multiple dispersing tooth groups are provided, and each dispersing tooth group is composed of multiple dispersing tooth rods 8.

[0027] The feeding conveyor belt 3 is equipped with auxiliary rollers 12 inside. There are multiple sets of auxiliary rollers 12, and each end of the multiple sets of auxiliary rollers 12 is equipped with a support 13 that is installed on the feeding platform 1. The auxiliary rollers are rotatably connected to the support 13. The multiple sets of auxiliary rollers 12 can assist the operation of the feeding conveyor belt 3, so that the feeding conveyor belt 3 has good support capacity to stably feed wood chip fuel.

[0028] This invention features a rotating first anti-blocking roller 5 on one side of the outlet end of the feeding conveyor belt 3, and a rotating second anti-blocking roller 6 inside the feeding hopper 2 near the first anti-blocking roller 5. The first and second anti-blocking rollers 5 and 6 can prevent a large amount of wood chips in the feeding hopper 2 from being transported into the boiler at once by the feeding conveyor belt 3, causing boiler feeding blockage. When the first and second anti-blocking rollers 5 and 6 rotate, they can disperse the wood chips through multiple sets of dispersing teeth 8, preventing the wood chips from clogging in the feeding hopper 2, improving feeding uniformity, and achieving stable and unobstructed feeding.
