Description

Technical Field

[0001] This utility model relates to the field of pellet conveying technology, and in particular to a conveyor for biomass pellet processing. Background Technology

[0002] Biomass pellets are a renewable energy source made from agricultural and forestry waste through cold-forming and densification processes. They are characterized by high combustion efficiency and zero sulfur and phosphorus emissions. The biomass pelleting process involves mixing all components, followed by crushing, drying, and pelletizing.

[0003] A related technology, Chinese patent CN222757315U, discloses a biomass pellet raw material processing auger conveyor. It includes a shell, an auger rotatably mounted inside the shell, a discharge channel on the bottom right side of the shell, and an inlet channel on the top left side of the shell. A baffle is slidably mounted inside the inlet channel, and a rotating rod is rotatably mounted inside the inlet channel. A dispersing rod is installed on the outside of the rotating rod, located below the baffle. Biomass pellets are fed into the inlet channel, and the rotating dispersing rod collidees and disperses the raw material. The auger rotates and conveys the biomass pellets to the discharge channel, exiting the shell. When there is a large amount of raw material in the shell, the baffle moves to reduce the flow space in the inlet channel, controlling the flow speed and preventing the auger from becoming clogged due to excessive raw material.

[0004] In the process of developing this application, the inventors discovered that the technology has at least the following problems: under the obstruction of the baffle, the biomass raw materials in the feed channel will gradually accumulate on the baffle, causing the baffle to easily deform and get stuck, thereby affecting the normal feeding of biomass pellets. Utility Model Content

[0005] To facilitate control of the biomass pellet feeding speed, this application provides a conveyor for biomass pellet processing.

[0006] The technical solution of the conveyor for biomass pellet processing provided in this application is as follows: A conveyor for biomass pellet processing includes a housing, an auger rotatably disposed within the housing, a discharge port at the bottom of the housing, a feed port at the top of the housing, a feeding cylinder disposed above the housing at an incline, a guide port on the side wall of the feeding cylinder, a feeding pipe communicating with the guide port, the bottom end of the feeding pipe communicating with the feed port, and a baffle column slidably disposed within the feeding cylinder, the side wall of the baffle column abutting against the inner wall of the feeding cylinder, the baffle column covering the guide port.

[0007] By adopting the above technical solution, biomass pellets are fed into the feeding cylinder. The biomass pellets slide downwards along the feeding cylinder. When the biomass pellets slide to the guide port, they fall into the feeding pipe. The biomass pellets in the feeding pipe enter the shell from the inlet. The auger inside the shell rotates and transports the biomass pellets to the outlet to be discharged from the shell. When there are many biomass pellets in the shell, the baffle column moves along the feeding cylinder to gradually cover the guide port, reducing the size of the guide port and achieving the effect of controlling the feeding speed of biomass pellets. This reduces the possibility of auger blockage caused by too many biomass pellets in the shell. Furthermore, the force direction of the baffle column is consistent with the direction of movement of the baffle column, making it less likely for the baffle column to get stuck.

[0008] Preferably, a conveying motor is fixedly installed on the housing, the output shaft of the conveying motor passes through the housing, the output shaft of the conveying motor is rotatably connected to the housing, the output shaft of the conveying motor is fixedly connected to one end of the auger, and the other end of the auger is rotatably connected to the housing.

[0009] By adopting the above technical solution, the conveyor motor drives the auger to rotate.

[0010] Preferably, a bulk material motor is fixedly installed on the side wall of the feeding pipe, the output shaft of the bulk material motor passes through the side wall of the feeding pipe, the output shaft of the bulk material motor is rotatably connected to the side wall of the feeding pipe, a bulk material shaft is fixedly installed on the output shaft of the bulk material motor, the bulk material shaft is rotatably connected to the inner wall of the feeding pipe, and several bulk material rods are fixedly installed on the bulk material shaft.

[0011] By adopting the above technical solution, the bulk material motor starts and drives the bulk material shaft to rotate, the rotation of the bulk material shaft drives the bulk material rod to rotate, and the rotation of the bulk material rod disperses the biomass pellets falling into the feed pipe.

[0012] Preferably, the feeding cylinder includes a first cylinder and a second cylinder, with the bottom end of the first cylinder and the top end of the second cylinder communicating with each other. The inner diameter of the first cylinder is smaller than the inner diameter of the second cylinder. The baffle column is slidably disposed inside the first cylinder and the second cylinder. The side wall of the baffle column is in contact with the inner wall of the first cylinder, and there is a gap between the side wall of the baffle column and the inner wall of the second cylinder. The guide port is opened on the side wall of the first cylinder. An inlet pipe is connected to the end of the first cylinder away from the second cylinder. A purge air pipe is disposed through the second cylinder. A plurality of purge nozzles are connected to the purge air pipe, and the purge nozzles face the side wall of the baffle column.

[0013] By adopting the above technical solution, biomass pellets are fed into the feed pipe, and the biomass pellets in the feed cylinder fall into the first feed cylinder. The biomass pellets in the first feed cylinder slide down along the first feed cylinder. When the biomass pellets slide to the guide port, the biomass pellets fall from the guide port into the feed pipe. When the baffle column retracts into the second feed cylinder, the purging nozzle purifies the baffle column.

[0014] Preferably, both the first and second material cylinders are inclined, the first and second material cylinders are arranged along the same straight line, and the lengths of both the first and second material cylinders are greater than the length of the baffle column.

[0015] By adopting the above technical solution, it is convenient for the baffle column to move within the first and second material cylinders.

[0016] Preferably, a discharge port is provided through the side wall of the second material cylinder, and a collection bag is connected to the discharge port.

[0017] By adopting the above technical solution, the biomass pellets in the second feed cylinder fall into the collection bag from the discharge port.

[0018] Preferably, a drive piston cylinder is fixedly installed at the end of the second material cylinder away from the first material cylinder. The output shaft of the drive piston cylinder passes through the bottom end of the second material cylinder, and the output shaft of the drive piston cylinder is slidably connected to the bottom wall of the second material cylinder. The output shaft of the drive piston cylinder is also fixedly connected to the baffle column.

[0019] By adopting the above technical solution, the output shaft of the piston cylinder is extended and retracted to drive the baffle column to move.

[0020] Preferably, the end of the baffle post away from the output shaft of the drive piston cylinder has a tapered surface.

[0021] By adopting the above technical solution, when the baffle column is inserted into the first material cylinder from the second material cylinder, the conical surface forms a guide for the baffle column, making it easier for the baffle column to be inserted into the first material cylinder.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up a shell, auger, discharge port, inlet, feeding cylinder, guide port, feeding pipe and baffle column, the feeding speed of biomass pellets can be controlled, reducing the situation of auger blockage caused by too many biomass pellets in the shell. In addition, the force direction of the baffle column is consistent with the movement direction of the baffle column, making it less likely for the baffle column to get stuck. 2. By setting up a bulk material motor, a bulk material shaft, and a bulk material rod, the biomass pellets falling into the feed pipe are broken up; 3. The baffle column is moved by setting a drive piston cylinder. Attached Figure Description

[0027] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0028] This application discloses a conveyor for biomass pellet processing. (Refer to...) Figure 1 The system includes a housing 1, with a discharge port 12 at the bottom and a feed port 11 at the top. A conveyor motor 21 is installed at one end of the housing 1, and the output shaft of the conveyor motor 21 passes through the housing 1 and is rotatably connected to the housing 1. An auger 2 is installed on the output shaft of the conveyor motor 21, and the other end of the auger 2 is rotatably connected to the housing 1. The conveyor motor 21 drives the auger 2 to rotate. A feeding cylinder 3 is disposed above the housing 1 and is inclined by a steel structure support. A guide port 311 is opened on the side wall of the feeding cylinder 3, which is opposite to the feed port 11. A feeding pipe 4 is connected between the guide port 311 and the feed port 11. A baffle post 5 is slidably disposed inside the feeding cylinder 3, with its side wall fitting against the inner wall of the feeding cylinder 3, and the baffle post 5 is used to cover the guide port 311. Biomass pellets are fed into the feeding cylinder 3, and the biomass pellets inside the feeding cylinder 3 slide downwards along the feeding cylinder 3. When the biomass pellets slide to the feed inlet 311, they fall into the feed pipe 4. The biomass pellets in the feed pipe 4 enter the housing 1 through the inlet 11. The auger 2 inside the housing 1 rotates, conveying the biomass pellets to the outlet 12 and discharging them out of the housing 1. When there are many biomass pellets in the housing 1, the baffle column 5 moves along the feed cylinder 3 to gradually cover the feed inlet 311, reducing the size of the feed inlet 311. This controls the feeding speed of the biomass pellets and reduces the risk of the auger 2 becoming clogged due to excessive biomass pellets in the housing 1. Furthermore, the direction of force on the baffle column 5 is consistent with its direction of movement, making it less likely for the baffle column 5 to jam.

[0029] Reference Figure 1 and Figure 2A bulk material motor 41 is installed on the side wall of the feeding pipe 4. The output shaft of the bulk material motor 41 passes through the side wall of the feeding pipe 4 and is rotatably connected to the side wall of the feeding pipe 4. A bulk material shaft 42 is installed on the output shaft of the bulk material motor 41 and is rotatably connected to the inner wall of the feeding pipe 4. Several bulk material rods 43 are installed on the bulk material shaft 42. When the bulk material motor 41 starts, it drives the bulk material shaft 42 to rotate. The rotation of the bulk material shaft 42 drives the bulk material rods 43 to rotate. The rotation of the bulk material rods 43 disperses the biomass pellets falling into the discharge pipe.

[0030] Reference Figure 1 and Figure 3 The feeding cylinder 3 includes a first feeding cylinder 31 and a second feeding cylinder 32, with the bottom end of the first feeding cylinder 31 and the top end of the second feeding cylinder 32 connected to each other. Both the first feeding cylinder 31 and the second feeding cylinder 32 are inclined and aligned along the same straight line. The lengths of both the first feeding cylinder 31 and the second feeding cylinder 32 are greater than the length of the baffle post 5, which is slidably disposed within the first feeding cylinder 31 and the second feeding cylinder 32. The inner diameter of the first feeding cylinder 31 is smaller than the inner diameter of the second feeding cylinder 32. The sidewall of the baffle post 5 is in contact with the inner wall of the first feeding cylinder 31, while a gap exists between the sidewall of the baffle post 5 and the inner wall of the second feeding cylinder 32. A guide port 311 is located on the sidewall of the first feeding cylinder 31, and an inlet pipe 312 is connected to the end of the first feeding cylinder 31 furthest from the second feeding cylinder 32. Biomass pellets are fed into the feed pipe 312, where they fall into the first feed cylinder 31. The pellets slide downwards along the first feed cylinder 31, and when they reach the guide port 311, they fall into the feed pipe 4. A purge air pipe 6 is installed through the second feed cylinder 32, with several purge nozzles 61 connected to it, facing the side wall of the baffle post 5. A discharge port 321 is opened through the side wall of the second feed cylinder 32, with a collection bag 322 connected to it. When the baffle post 5 retracts into the second feed cylinder 32, the purge nozzles 61 purge the baffle post 5, and the biomass pellets in the second feed cylinder 32 fall from the discharge port 321 into the collection bag 322.

[0031] Reference Figure 1 and Figure 3 A drive piston cylinder 51 is installed at the end of the second material cylinder 32 away from the first material cylinder 31. The output shaft of the drive piston cylinder 51 passes through the bottom end of the second material cylinder 32 and is slidably connected to the bottom wall of the second material cylinder 32. The output shaft of the drive piston cylinder 51 is fixedly installed at one end of the baffle post 5, and a tapered surface 52 is formed at the end of the baffle post 5 away from the output shaft of the drive piston cylinder 51. The extension and retraction of the output shaft of the drive piston cylinder 51 drives the baffle post 5 to move. When the baffle post 5 is inserted from the second material cylinder 32 into the first material cylinder 31, the tapered surface 52 guides the baffle post 5, facilitating its insertion into the first material cylinder 31.

[0032] The implementation principle of a biomass pellet processing conveyor according to an embodiment of this application is as follows: Biomass pellets in the feeding cylinder 3 slide downwards along the feeding cylinder 3. When the biomass pellets slide to the guide port 311, they fall from the guide port 311 into the feeding pipe 4. The biomass pellets in the feeding pipe 4 enter the housing 1 from the inlet 11. The auger 2 inside the housing 1 rotates and conveys the biomass pellets to the outlet 12 for discharge from the housing 1. When there are many biomass pellets in the housing 1, the baffle column 5 moves along the feeding cylinder 3 to gradually cover the guide port 311, reducing the size of the guide port 311, thereby controlling the feeding speed of the biomass pellets and reducing the possibility of the auger 2 being blocked due to too many biomass pellets in the housing 1. Furthermore, the force direction of the baffle column 5 is consistent with the movement direction of the baffle column 5, making it less likely for the baffle column 5 to get stuck.

[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
