Abstract
Description
Technical Field
[0001] This utility model belongs to the field of biomass pellet drying technology, specifically, it relates to a drying device for biomass pellet production. Background Technology
[0002] Biomass pellets are made from agricultural materials such as rice husks, straw, sawdust, peanut shells, and branches. These materials are processed into fuel through crushing, drying, and extrusion processes, thus replacing traditional fossil fuels. They are widely used in processing and production because they do not pollute the environment and are renewable resources.
[0003] Chinese utility model patent CN220417924U discloses a drying device for biomass pellet production, including a shell. A motor is fixedly connected to the top of the shell, and a connecting shaft is fixedly connected to the output shaft of the motor. A contact block is rotatably connected to the outer wall of the connecting shaft, and the contact block is fixedly connected to the inner wall of the shell. A filter plate is elastically connected to the top of the contact block via a return spring. A contact tube is fixedly connected to the lower surface of the filter plate. A crushing plate is fixedly connected to the outer wall of the connecting shaft, and a fixing plate is fixedly connected to the upper inner wall of the shell. The powder on the filter plate contacts and impacts the upper surface of the filter plate, which can break up some of the clumps of powder. Finally, the powder is completely broken up by the alternating crushing plate and the fixing plate, which can effectively improve the efficiency of subsequent drying and make the drying effect better.
[0004] The aforementioned existing technology also has the following drawbacks: the powder needs to be filtered with the biomass pellets beforehand, which increases the filtration process and requires two drying devices to dry the biomass pellets and powder, thus increasing production costs. Utility Model Content
[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.
[0006] To address the issue raised in the background art that the powder needs to be filtered with biomass pellets beforehand, which increases the filtration process and requires two drying devices to dry both the biomass pellets and the powder, thus increasing production costs, the present invention adopts the following technical solution.
[0007] A drying device for biomass pellet production includes a mounting base plate, with supporting vertical plates fixedly connected to both sides of the upper end of the mounting base plate. A connecting outer cylinder is detachably connected to the upper end of the supporting vertical plates. A sealing lid is rotatably connected to the outer wall of the connecting outer cylinder. A rotating inner cylinder is rotatably connected to the inside of the connecting outer cylinder. There is a space between the outer wall of the rotating inner cylinder and the inner wall of the connecting outer cylinder. Multiple filter grids are provided on the rotating inner cylinder. A rotating assembly is installed on one side of the upper end of the mounting base plate, which causes the rotating inner cylinder to rotate inside the connecting outer cylinder. A drying assembly is installed on one side of the upper end of the mounting base plate, which delivers hot air into the connecting outer cylinder.
[0008] Preferably, a crushing component is installed on the rotating inner cylinder to crush the powder.
[0009] Preferably, the outer wall of the outer cylinder is provided with vent holes, and a filter element is provided on the vent holes. A lifting plate is fixedly connected to the inner wall of the rotating inner cylinder.
[0010] Preferably, the rotating assembly includes a drive motor, a drive sprocket, a linkage chain, a meshing sprocket, and a transmission rod. The inner cylinder is fixedly connected to the outer wall of the connecting outer cylinder, and the transmission rod extends through the connecting outer cylinder. The outer wall of the transmission rod is fixedly connected to the meshing sprocket. The upper side of the mounting base plate is detachably connected to the drive motor. The rotating end of the drive motor is detachably connected to the drive sprocket. The outer walls of the drive sprocket and the meshing sprocket are sleeved with a linkage chain. The rotation of the drive motor drives the drive sprocket to rotate, and the linkage chain drives the meshing sprocket to rotate.
[0011] Preferably, the crushing assembly includes connecting vertical plates and crushing rollers. Opposite connecting vertical plates are fixedly connected to both sides of the outer wall of the rotating inner cylinder, and a crushing roller is rotatably connected between the two connecting vertical plates. The crushing roller contacts the inner wall of the connecting outer cylinder. When the rotating inner cylinder rotates inside the connecting outer cylinder, it drives the crushing roller to rotate. The friction between the crushing roller and the inner wall of the connecting outer cylinder causes the crushing roller to rotate.
[0012] Preferably, the drying assembly includes a hot air blower and a hot air duct. The hot air duct is detachably connected to the air outlet end of the hot air blower. The hot air duct passes through the inner wall of the connecting outer cylinder and is flush with the inner wall of the connecting outer cylinder. A filter screen is detachably connected to the end of the hot air duct located inside the connecting outer cylinder. The hot air blows hot air into the interior of the connecting outer cylinder and the rotating inner cylinder through the hot air duct.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] 1. The drive motor in the rotating assembly rotates, driving the drive sprocket to rotate. The linkage chain drives the meshing sprocket to rotate, which in turn causes the inner cylinder to rotate. The rotation of the inner cylinder causes the powder particles to fall from the filter grid into the interior of the connecting outer cylinder. The hot air blown by the hot air fan in the drying assembly is blown into the interior of the connecting outer cylinder and the rotating inner cylinder through the hot air pipe, which can dry the biomass particles and powder inside. The filter screen can prevent powder from entering the interior of the hot air pipe. Thus, a single device can achieve the effect of drying biomass particles and powder simultaneously, reducing production and operating costs.
[0015] 2. The vent holes prevent excessive pressure inside the outer cylinder, and the filter element prevents powder from being blown out.
[0016] 3. Through the set crushing component, the rotating inner cylinder drives the crushing roller to rotate when it rotates inside the connecting outer cylinder. The crushing roller rotates due to the friction between the crushing roller and the inner wall of the connecting outer cylinder, thereby crushing more powder that falls into the inner wall of the connecting outer cylinder, thus improving the drying effect of the powder.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0027] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.
[0028] like Figure 1 The diagram shows a preferred embodiment of a drying device for biomass pellet production. This embodiment includes a mounting base plate 100. Supporting vertical plates 101 are fixedly connected to both sides of the upper end of the mounting base plate 100. A connecting outer cylinder 102 is detachably connected to the upper end of the supporting vertical plates 101. The outer wall of the connecting outer cylinder 102 has ventilation holes, each with a filter element. A rotating inner cylinder 200 is rotatably connected inside the connecting outer cylinder 102. A space exists between the outer wall of the rotating inner cylinder 200 and the inner wall of the connecting outer cylinder 102. Multiple filter grids 201 are provided on the rotating inner cylinder 200. The outer wall of the connecting outer cylinder 102 is rotatably connected to… The device has a sealed lid 103, and a hot air blower 300 is installed on one side of the upper end of the mounting base plate 100. The hot air blower 300 introduces hot air into the connecting outer cylinder 102. In this embodiment, the biomass pellets to be dried are placed inside the rotating inner cylinder 200. The rotation of the rotating inner cylinder 200 causes the powder particles to fall from the filter grid 201 into the connecting outer cylinder 102. The hot air blown into the connecting outer cylinder 102 by the hot air blower 300 dries the biomass pellets and powder. The vent holes prevent the pressure inside the connecting outer cylinder 102 from becoming too high, and the filter element prevents the powder from being blown out. Thus, a single device can be used to dry both biomass pellets and powder simultaneously, reducing production and operating costs.
[0029] like Figure 2 As shown, this is a schematic diagram of the lifting plate structure in this embodiment. The inner wall of the rotating inner cylinder 200 is fixedly connected to the lifting plate 202. In this embodiment, the lifting plate 202 can lift the biological particles inside the rotating inner cylinder 200 to a higher position during the rotation of the rotating inner cylinder 200. When the lifting plate 202 rotates to an inclined downward position, the lifted biological particles fall downward. Combined with the hot air from the hot air blower 300, the drying effect of the biological particles can be better.

A transmission rod that passes through the outer cylinder 102 is fixedly connected to the outer wall of the rotating inner cylinder 200 near the outer wall of the connecting outer cylinder 102. A meshing sprocket 206 is fixedly connected to the outer wall of the transmission rod. A drive motor 203 is detachably connected to one side of the upper end of the mounting base plate 100. A drive sprocket 204 is detachably connected to the rotating end of the drive motor 203. A linkage chain 205 is sleeved on the outer wall of the drive sprocket 204 and the meshing sprocket 206. In this embodiment, the drive sprocket 204 is driven to rotate by the rotation of the drive motor 203, and the meshing sprocket 206 is driven to rotate by the linkage chain 205, thereby enabling the rotating inner cylinder 200 to rotate.

A crushing roller 208 is rotatably connected between the two connecting vertical plates 207. The crushing roller 208 contacts the inner wall of the connecting outer cylinder 102. In this embodiment, when the rotating inner cylinder 200 rotates inside the connecting outer cylinder 102, it drives the crushing roller 208 to rotate. The friction between the crushing roller 208 and the inner wall of the connecting outer cylinder 102 causes the crushing roller 208 to rotate, thereby enabling more powder falling into the inner wall of the connecting outer cylinder 102 to be crushed, thus improving the drying effect of the powder.

The crushing components include, but are not limited to, the connecting vertical plate 207 and the crushing roller 208. Any component that can crush powder can be used in this embodiment.
[0034] like Figure 4As shown, this is a schematic diagram of the drying component structure in this embodiment. The outlet end of the hot air blower 300 is detachably connected to a hot air pipe 301. The hot air pipe 301 passes through the inner wall of the connecting outer cylinder 102 and is flush with the inner wall of the connecting outer cylinder 102. The end of the hot air pipe 301 located inside the connecting outer cylinder 102 is detachably connected to a filter screen 302. In this embodiment, the hot air blown by the hot air blower 300 through the hot air pipe 301 into the interior of the connecting outer cylinder 102 and the rotating inner cylinder 200 can dry the biological particles and powder inside, and the filter screen 302 can prevent powder from entering the interior of the hot air pipe 301.
