Description
Technical Field
[0001] The utility model relates to the technical field of boilers, in particular to a feeding and unloading device for boiler combustion particle materials. Background Art
[0002] Boilers are commonly used heating equipment in northern China. With the increasing awareness of environmental protection and the upgrading of fuels, traditional coal-fired boilers have been abandoned and replaced by biomass boilers that burn biomass.
[0003] Whether it is a traditional coal-fired boiler or a biomass boiler, fuel needs to be added intermittently during operation. Biomass fuel is granular. There are two types of automatic feeding devices for existing boilers. One is an auger-type conveying feeding device. The problem is that the material near the end of the auger will leak out and enter the furnace after transportation, resulting in inaccurate feeding amount, and the feeding amount cannot be accurately controlled; the other is a closed air door type rotary feeding. The problem is that when the rotating mechanism rotates, there is a situation where the material is stuck, such as the detachable and maintainable rotary feeder of the biomass boiler disclosed in China CN211475995.
[0004] Therefore, the applicant has proposed a feeding and unfeeding device having a simple structure, good use effect, capable of accurately controlling the feeding amount, and capable of effectively avoiding material jamming, and a boiler composed of the feeding and unfeeding device. Summary of the invention
[0005] The technical problem to be solved by the utility model is to provide a boiler feeding and unloading device which has simple structure, good use effect, can accurately control the unloading amount and can avoid material jamming during use.
[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0007] A feeding device for a boiler combustion particulate material comprises a silo (4), a feeding pipe, and a feeding mechanism. One end of the feeding pipe is connected to the lower part of the silo (4), and the other end is a material discharge port (1). The feeding mechanism is arranged at the connection between the silo (4) and the feeding pipe or in the feeding pipe. The feeding mechanism comprises a feeding barrel (2). The feeding barrel (2) is in the shape of a tube with two ends closed. The feeding barrel (2) is arranged on a feeding barrel rotating shaft (3) and rotates with the feeding barrel rotating shaft (3). A feeding port (5) is arranged on the barrel wall of the feeding barrel (2). When the feeding port (5) faces the silo, the material in the silo (4) can enter the feeding barrel (2). The feeding barrel (2) continues to rotate. When the feeding port (5) faces the material discharge port (1), the material is discharged from the feeding barrel (2).
[0008] In actual use: the material taking barrel (2) of the feeding and unloading mechanism is arranged between the silo (4) and the unloading pipe, or is arranged in the unloading pipe. Only when the material taking barrel (2) rotates can the material taking and unloading be realized, that is, when the feeding port (5) of the material taking barrel (2) faces the silo (4), the material in the silo (4) falls into the material taking barrel (2) under the action of gravity. When unloading is required, the material taking barrel rotating shaft (3) drives the material taking barrel (2) to rotate, so that the feeding port (5) rotates to the direction of the material discharge port (1). At this time, the material is discharged from the material discharge port (1) under the action of gravity, and the discharged material enters the furnace for combustion.
[0009] The technical effect of the utility model is that the material taking and feeding process is realized by rotating the material taking barrel (2), and during the material taking process, the material will fill the material taking barrel (2), and the material taking barrel (2) continues to be rotated, and there will be no material jamming between the outer surface of the material taking barrel (2) and the inner wall of the silo (4) or the feeding tube. The reason is that when the material taking barrel (2) is filled with material and the material taking barrel (2) continues to be rotated, the external material cannot continue to enter the material taking barrel (2), but is in a state of relative motion, that is, the material storage area is filled with material, and it is in a state of relative friction with the material outside the material storage area, which can effectively avoid the phenomenon of material jamming at the feeding port (5) of the material taking barrel (2).
[0010] As an improvement, the material taking barrel (2) is provided with a plurality of feed ports (5), and the material storage area in the material taking barrel (2) corresponding to each feed port (5) is independent, and when one of the feed ports (5) is facing the silo (4), only one feed port (5) can take material into the material taking barrel (2).
[0011] In actual use, three or four feed ports can be provided, and the storage area corresponding to each feed port (5) is relatively independent, that is, each feed port (5) corresponds to a storage area in its own material collection barrel (2). When the material collection barrel (2) rotates, the feed port (5) located at the top is used for feeding, and the feed port (5) located at the bottom is used for discharging. In this cycle, discharging can be achieved by rotating only half a circle or one-third of a circle.
[0012] As an improvement, the inner cavity of the material taking barrel (2) is a material storage area, and the radial cross-section of the material storage area is circular or fan-shaped.
[0013] When the material storage area is circular, the interior of the entire material taking barrel (2) is hollow. When the material storage area is fan-shaped, only this part can store material, and the rest of the part cannot store material.
[0014] As an improvement, the outer surface of the material taking barrel (2) is arranged to fit or be tangent to the inner wall of the material discharging tube. The outer surface of the material taking barrel (2) is tangent to the inner wall of the material discharging tube.
[0015] In actual use: it can prevent the material from leaking due to the gap between the outer wall of the material taking barrel (2) and the material discharge pipe being too large. The above-mentioned "fitting" and "tangent" both refer to the gap being small and not in contact.
[0016] A boiler, characterized in that a feeding device is provided at a feeding place of a furnace, the feeding device having the following structure: comprising a silo (4), a feeding pipe, and a feeding mechanism, one end of the feeding pipe is connected to the lower part of the silo (4), and the other end is a material discharge port (1), the feeding mechanism is provided at the connection between the silo (4) and the feeding pipe, the feeding mechanism comprises a feeding barrel (2), the feeding barrel (2) is in the shape of a tube with two ends closed, the feeding barrel (2) is provided on a feeding barrel rotating shaft (3), and rotates with the feeding barrel rotating shaft (3), a feeding port (5) is provided on the barrel wall of the feeding barrel (2), the feeding barrel (2) rotates, when the feeding port (5) faces the silo, the material in the silo (4) can enter the feeding barrel (2), the feeding barrel (2) continues to rotate, when the feeding port (5) faces the material discharge port (1), the material is discharged from the feeding barrel (2).
[0017] In actual use: the material taking barrel (2) of the feeding and unloading mechanism is arranged between the silo (4) and the unloading pipe, or is arranged in the unloading pipe. Only when the material taking barrel (2) rotates can the material taking and unloading be realized, that is, when the feeding port (5) of the material taking barrel (2) faces the silo (4), the material in the silo (4) falls into the material taking barrel (2) under the action of gravity. When unloading is required, the material taking barrel rotating shaft (3) drives the material taking barrel (2) to rotate, so that the feeding port (5) rotates to the direction of the material discharge port (1). At this time, the material is discharged from the material discharge port (1) under the action of gravity, and the discharged material enters the furnace for combustion.
[0018] The technical effect of the utility model is that the material taking and feeding process is realized by rotating the material taking barrel (2), and during the material taking process, the material will fill the material taking barrel (2), and the material taking barrel (2) continues to be rotated, and there will be no material jamming between the outer surface of the material taking barrel (2) and the inner wall of the silo (4) or the feeding tube. The reason is that when the material taking barrel (2) is filled with material and the material taking barrel (2) continues to be rotated, the external material cannot continue to enter the material taking barrel (2), but is in a state of relative motion, that is, the material storage area is filled with material, and it is in a state of relative friction with the material outside the material storage area, which can effectively avoid the phenomenon of material jamming at the feeding port (5) of the material taking barrel (2).
[0019] As an improvement, the material taking barrel (2) is provided with a plurality of feed ports (5), and the material storage area in the material taking barrel (2) corresponding to each feed port (5) is independent, and when one of the feed ports (5) is facing the silo (4), only one feed port (5) can take material into the material taking barrel (2).
[0020] In actual use, three or four feed ports can be provided, and the storage area corresponding to each feed port (5) is relatively independent, that is, each feed port (5) corresponds to a storage area in its own material collection barrel (2). When the material collection barrel (2) rotates, the feed port (5) located at the top is used for feeding, and the feed port (5) located at the bottom is used for discharging. In this cycle, discharging can be achieved by rotating only half a circle or one-third of a circle.
[0021] As an improvement, the inner cavity of the material taking barrel (2) is a material storage area, and the radial cross-section of the material storage area is circular or fan-shaped.
[0022] When the material storage area is circular, the interior of the entire material taking barrel (2) is hollow. When the material storage area is fan-shaped, only this part can store material, and the rest of the part cannot store material.
[0023] As an improvement, the outer surface of the material taking barrel (2) is arranged to fit or be tangent to the inner wall of the material discharging tube. The outer surface of the material taking barrel (2) is tangent to the inner wall of the material discharging tube.
[0024] In actual use: it can prevent the material from leaking due to the gap between the outer wall of the material taking barrel (2) and the material discharge pipe being too large. The above-mentioned "fitting" and "tangent" both refer to the gap being small and not in contact.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] The inner cavity of the material taking barrel (2) is a material storage area, and the radial cross section of the material storage area is circular. When the material storage area is circular, the entire interior of the material taking barrel (2) is hollow.
[0033] The outer surface of the material taking barrel (2) is in contact with or tangent to the inner wall of the material discharging tube. The outer surface of the material taking barrel (2) is tangent to the inner wall of the material discharging tube.
[0034] In actual use: it can prevent the material from leaking due to the gap between the outer wall of the material taking barrel (2) and the material discharge pipe being too large. The above-mentioned "fitting" and "tangent" both refer to the gap being small and not in contact.
[0035] In actual use: the material taking barrel (2) of the feeding and unloading mechanism is arranged in the unloading pipe. Only when the material taking barrel (2) rotates can the material taking and unloading be realized. That is, when the feeding port (5) of the material taking barrel (2) faces the silo (4), the material in the silo (4) falls into the material taking barrel (2) under the action of gravity. When unloading is required, the material taking barrel rotating shaft (3) drives the material taking barrel (2) to rotate, so that the feeding port (5) rotates to the direction of the material discharge port (1).

The feeding barrel (2) is arranged on a feeding barrel rotating shaft (3) and rotates with the feeding barrel rotating shaft (3). A feeding port (5) is arranged on the barrel wall of the feeding barrel (2). When the feeding port (5) faces the silo, the material in the silo (4) can enter the feeding barrel (2). The feeding barrel (2) continues to rotate. When the feeding port (5) faces the material discharge port (1), the material is discharged from the feeding barrel (2).
[0039] The inner cavity of the material taking barrel (2) is a material storage area, and the radial cross section of the material storage area is fan-shaped. When the material storage area is fan-shaped, only this part can store material, and the rest of the part cannot store material.
[0040] In actual use: the material taking barrel (2) of the feeding and unloading mechanism is arranged between the silo (4) and the unloading pipe. Only when the material taking barrel (2) rotates can the material taking and unloading be realized. That is, when the feeding port (5) of the material taking barrel (2) faces the silo (4), the material in the silo (4) falls into the material taking barrel (2) under the action of gravity. When unloading is required, the material taking barrel rotating shaft (3) drives the material taking barrel (2) to rotate, so that the feeding port (5) rotates to the direction of the material discharge port (1). At this time, the material is discharged from the material discharge port (1) under the action of gravity, and the discharged material enters the furnace for combustion.
[0041] The outer surface of the material taking barrel (2) is in contact with or tangent to the inner wall of the material discharging tube. The outer surface of the material taking barrel (2) is tangent to the inner wall of the material discharging tube.
[0042] In actual use: it can prevent the material from leaking due to the gap between the outer wall of the material taking barrel (2) and the material discharge pipe being too large. The above-mentioned "fitting" and "tangent" both refer to the gap being small and not in contact.
[0043] The use effect is as follows: the material taking and feeding process is realized by rotating the material taking barrel (2), and during the material taking process, the material will fill the material taking barrel (2), and when the material taking barrel (2) continues to be rotated, there will be no material jamming between the outer surface of the material taking barrel (2) and the inner wall of the silo (4) or the feeding tube. The reason is that when the material taking barrel (2) is filled with material, the material outside cannot continue to enter the material taking barrel (2) and is in a state of relative motion, that is, the material storage area is filled with material and is in a state of relative friction with the material outside the material storage area, which can effectively avoid the phenomenon of material jamming at the feeding port (5) of the material taking barrel (2).
[0044] Example 3: Reference Figure 3 , is a schematic diagram of the structure of Example 3 of the utility model. Compared with Example 1 or Example 2, the difference of this embodiment is that:
