Description

Technical Field

[0001] The utility model relates to the technical field of biomass particle manufacturing equipment, in particular to a biomass particle cooling bin. Background Art

[0002] Biomass pellets are obtained by cold compacting crushed biomass materials such as straw and forestry waste using rollers and ring dies. This processing method significantly increases the density of the raw materials, making it easier to store and transport, and greatly improves the combustion performance of biomass.

[0003] However, in the production process of biomass pellet fuel, the pellets usually need to go through a heating and drying process after forming to ensure that they are fully burned and release sufficient heat. However, the pellets are at a high temperature after heating, and it takes too long to directly stack them for natural cooling, and the bagging efficiency is low.

[0004] If air cooling is used, it is easy to cause dust to fly, resulting in a very bad working environment for workers. Utility Model Content

[0005] The utility model aims to solve the problems of long cooling time and large air-cooling dust in the production process of biomass particles in the prior art, and proposes a biomass particle cooling bin.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a biomass particle cooling bin, including a cooling bin shell, and also including: a first cooling device, arranged in the cooling bin shell, including a first shell that passes through from top to bottom and a plurality of vertically arranged first cooling plates arranged in the first shell; a second cooling device, including a second shell that is sleeved on the outside of the first shell and a plurality of second cooling plates that are arranged in the second shell and vertically arranged, and a supporting device for driving the second shell to move up and down, and the second cooling plate and the first cooling plate are arranged in a gap; a baffle, arranged below the second cooling device, for sealing the gap between adjacent second cooling plates.

[0007] Preferably, it also includes: a first sealing plug, which is arranged at one end of the second cooling plate close to the first cooling plate and is used to seal the gap between two adjacent first cooling plates when the second cooling plate is close to the first cooling plate.

[0008] Preferably, the cross-section of the first sealing plug is triangular.

[0009] Preferably, the baffle includes a plate body arranged inside the cooling bin shell and a plurality of second sealing plugs arranged on a side of the plate body close to the second cooling device, the second sealing plugs are located between adjacent second cooling plates, and through grooves are provided between adjacent second sealing plugs.

[0010] Preferably, it also includes: a vibration device, which is arranged on the first cooling device and includes a prism-shaped screen and a vibration motor arranged on the screen.

[0011] Preferably, the first shell is connected to the cooling bin shell via an elastic support rod.

[0012] Preferably, a protective plate located outside the second cooling plate is provided on one side of the second shell close to the baffle.

[0013] Preferably, an outward-expanding air guide port is provided on the top of the cooling bin shell.

[0014] Compared with the prior art, the advantages and positive effects of the utility model are:

[0015] 1. Cooling is achieved by setting a cooling plate. The cooling plate can be water-cooled or semiconductor-cooled, which has the advantages of low noise, large temperature difference, and fast cooling. It also avoids the harm of a large amount of dust and noise caused by air cooling to workers and the environment.

[0016] 2. By setting the first cooling plate and the second cooling plate arranged in a gap, the intermediate biomass particles that are not fully cooled between the first cooling plates can fall between the second cooling plates and adhere to the second cooling plates to achieve further cooling, making the cooling more uniform and sufficient.

[0024] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0026] Embodiment 1:

[0027] like Figure 1 and Figure 2 As shown, a biomass particle cooling bin comprises a cooling bin shell 1 for cooling treatment, the processed biomass particles enter from the top feed port of the cooling bin shell 1 and are discharged from the bottom discharge port, the cooling bin shell 1 is provided with a first cooling device 2, a second cooling device 3, and a baffle 4 in sequence from top to bottom, the first cooling device 2 comprises a first shell 2-1 connected to the inner wall of the cooling bin shell 1, and a plurality of vertically arranged first cooling plates 2-2 arranged in the first shell 2-1, the second cooling device 3 comprises a second shell 3-1 sleeved outside the first shell 2-1, a plurality of vertically arranged second cooling plates 3-2, and a supporting device 3-3 arranged on the cooling bin shell 1 for driving the second cooling device 3 to move up and down, the first cooling plate 2-2 and the second cooling plate 3-2 are arranged in a gap, and liquid cooling pipes connected to an external refrigeration device are arranged in the first cooling plate 2-2 and the second cooling plate 3-2, when the biomass particles enter the first cooling device 2 for cooling, the top of the second cooling plate 3-2 blocks the bottom gap between the first cooling plates 2-2 to prevent the biomass particles from being blocked. The biomass particles fall, and at this time, the biomass particles are cooled between the first cooling plates 2-2. Because some of the middle biomass particles are far away from the first cooling plate 2-2, the cooling effect of this part is not good. After cooling for a period of time, the supporting device 3-3 can be a cylinder, and the cylinder body is fixed on the inner wall of the cooling bin shell 1. The cylinder telescopic rod is fixedly connected to the second shell 3-1. Driven by the cylinder, the second cooling plate 3-2 moves downward, and the baffle 4 blocks the gap below the second cooling plate 3-2, and the biomass particles between the first cooling plates 2-2 are blocked. The material particles fall between the second cooling plates 3-2. Because the second cooling plate 3-2 is located in the middle of the first cooling plate 2-2, during the falling process, those biomass particles that were originally located between the two first cooling plates 2-2 and have not been sufficiently cooled will be closer to the second cooling plate 3-2, so that they can be cooled more evenly. After the cooling is completed, the second cooling plate 3-2 rises, and the biomass particles fall from the gap between the second cooling plates 3-2, and after passing through the baffle 4, they fall to the discharge port at the bottom of the cooling bin shell 1 and are discharged.

[0028] Embodiment 2:

[0029] like Figure 5 As shown, a first sealing plug 3-4 is provided on the top of the second cooling plate 3-2. The first sealing plug 3-4 blocks the bottom gap between the first cooling plates 3-2, so that the second cooling plates 3-2 can be narrower, so that the space between adjacent second cooling plates 3-2 is larger and can accommodate more biomass particles.

[0030] Furthermore, in order to facilitate the biomass particles to fall from between the first cooling plates 2-2, the first sealing plug 3-4 is triangular, which can effectively guide and separate the fallen biomass particles from the middle.

[0031] Embodiment 3:

[0032] like Figure 6 As shown, the baffle 4 includes a plate body 4-1 disposed inside the cooling bin shell 1 and a plurality of second sealing plugs 4-2 disposed on one side of the plate body 4-1 close to the second cooling device 3, the second sealing plugs 4-2 are located between adjacent second cooling plates 3-2, and through grooves are provided between adjacent second sealing plugs 4-2. The second sealing plugs 4-2 are used to seal the gaps between the second cooling plates 3-2, and the through grooves between the second sealing plugs 4-2 can drain the biomass particles to the discharge port at the bottom of the cooling bin shell 1.

[0033] Embodiment 4:

[0034] like Figure 3 As shown, a vibration device 5 is provided on the first cooling device 2, and the vibration device 5 includes a frustum-shaped screen 5-1 and a vibrating motor 5-2. The top platform of the frustum-shaped screen 5-1 can accommodate the biomass particles conveyed by the conveyor belt, so that a smaller feed port can be opened on the top of the cooling bin shell 1 to reduce the emission of dust, and the side of the frustum facilitates the biomass particles to disperse and fall under the vibration of the vibrating motor 5-2, so that they are more evenly dispersed and fall into the first cooling device 2.

[0035] Embodiment 5:

[0036] like Figure 4 As shown, the first shell 2-1 is connected to the cooling bin shell 1 through an elastic support rod, so that the first shell 2-1 can vibrate under the drive of the vibration motor 5-2, thereby facilitating the falling of biomass particles.

[0037] In order to facilitate all the biomass particles falling from the second shell 3-1 to fall into the through grooves on the baffle 4, a protective plate 3-5 located outside the second cooling plate 3-2 is provided on one side of the second shell 3-1 close to the baffle 4.

[0038] In order to facilitate the biomass particles to fall into the first shell 2 - 1 , an outward-expanding guide port 2 - 3 is provided on the top of the cooling bin shell 1 .

[0039] Working process: the finished biomass particles are sent to the feed port in the cooling bin shell 1 through a conveyor belt, and then fall on the prism plane of the screen 5-1. Under the action of the vibrating motor 5-2, the biomass particles pass through the screen 5-1 and are dispersed and fall between the first cooling plates 2-2. At this time, the second cooling plate 3-2 is driven by the supporting device 3-3, and the first sealing plug 3-4 on the top of the second cooling plate 3-2 blocks the gap at the bottom of the adjacent first cooling plate 2-2, and the bottom of the second cooling plate 3-2 is separated from the baffle 4.

[0040] After the first cooling plate 2-2 cools the biomass particles, the biomass particles close to the first cooling plate 2-2 are cooled, but because the middle is far away from the first cooling plate 2-2, the cooling effect is poor. At this time, the second cooling plate 3-2 moves downward under the drive of the supporting device 3-3, and the biomass particles in the middle of the first cooling plate 2-2 fall to the middle of the second cooling plate 3-2, and under the diversion of the triangular first sealing plug 3-4, the biomass particles can be turned over, and the middle part of the biomass particles that have not been fully cooled can be closer to the second cooling plate 3-2, and at this time, the second sealing plug 4-2 of the baffle 4 will block the bottom gap between the second cooling plates 3-2, and after the second cooling plate 3-2 completes the cooling of the biomass particles, the second cooling plate 3-2 rises, and the biomass particles that have completed the cooling fall from the bottom gap of the second cooling plate 3-2, and then fall through the through groove on the baffle 4 to the bottom discharge port of the cooling bin shell 1. At the same time, new biomass particles fall between the first cooling plates 2-2, and at this time, the temperature of the first cooling plates 2-2 is low and the cooling effect is good.

[0041] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
