Description

Technical Field

[0001] This utility model belongs to the field of biomass pellet cooling and conveying devices, specifically, it relates to a biomass pellet cooling and conveying device. Background Technology

[0002] Biomass fuels are increasingly being used in industrial and civilian sectors. After processes such as crushing, mixing, extrusion, and drying, biomass fuel pellets at high temperatures need to be naturally cooled before they can be transported and packaged.

[0003] Chinese Patent No. CN222081614U discloses a biomass fuel biomass pellet cooling and conveying device. The device involves feeding biomass fuel biomass pellets into the feed pipe, turning on the cold air fan to discharge cold air into the tank through the air inlet pipe, starting the first motor to make the rotating shaft drive the spiral blades to rotate. Due to the nature of the spiral blades, the biomass fuel biomass pellets are rotated and turned while moving, allowing the cold air to come into better contact with them. The hot air is discharged from the air outlet pipe, and the valve is opened to discharge the cooled biomass fuel biomass pellets from the feed pipe.

[0004] However, the aforementioned biomass fuel biomass pellet cooling and conveying device drives the biomass fuel biomass pellets to move by driving spiral blades inside the tank, and then introduces air through the air inlet pipe at the end of the tank. This easily leads to the gas flowing in the upper part of the tank, resulting in a poor cooling effect on the biomass fuel biomass pellets conveyed in the lower part of the tank.

[0005] In view of this, this utility model is proposed. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a biomass pellet cooling and conveying device.

[0007] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0008] A biomass pellet cooling and conveying device includes a tank, a guide cylinder rotatably fitted inside the tank, a drive mechanism for driving the guide cylinder to rotate at one end of the tank, an auger blade inside the guide cylinder, multiple convex strips arranged circumferentially on the inner wall of the guide cylinder, an air outlet pipe rotatably fitted inside the tank, a first servo motor for driving the air outlet pipe to rotate on the inner wall of the tank, a fan on one side of the tank, the air outlet end of the fan fitting into the end of the air outlet pipe extending out of the tank, and multiple air outlet holes evenly distributed on the outer side of the air outlet pipe.

[0009] Optionally, multiple stirring blades are provided on the outside of the air outlet pipe, and there is a first distance between the outside of the stirring blades and the inner wall of the auger blades.

[0010] Optionally, the inner wall of the tank is provided with two first bearings, and the guide cylinder is fixed inside the two first bearings.

[0011] Optionally, the drive mechanism includes a second servo motor located on the outside of the tank, a gear located at one end of the output shaft of the second servo motor extending into the tank, and an external gear ring fixedly sleeved on the guide cylinder, with the gear meshing with the external gear ring.

[0012] Optionally, mounting holes are provided on both sides of the tank body, and a second bearing is provided in the mounting hole, with the vent pipe fixed in the two second bearings.

[0013] Optionally, a feed hopper is provided at the first end of the tank, and the feed hopper is connected to the guide cylinder.

[0014] Optionally, a discharge port is provided at the second end of the tank body. The discharge port is connected to the guide cylinder, and the height of the bottom surface of the inner wall of the discharge port gradually decreases from the end closer to the guide cylinder to the end farther away from the guide cylinder.

[0015] Optionally, an air vent valve is connected to the second end of the tank body, and the air vent valve is connected to the guide cylinder. Two bases are provided at the bottom of the tank body, and the height of the tank body and the guide cylinder gradually decreases from the end near the feed hopper to the end near the discharge port.

[0016] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0017] A fan drives cold air through multiple vents in the vent pipe inside the tank, directly blowing it onto the biomass pellets on the inner wall of the feed cylinder. This improves the heat dissipation of the biomass pellets. The drive mechanism is activated, causing the feed cylinder and auger blades to rotate, which in turn transports the biomass pellets within the feed cylinder. The feed cylinder also drives the convex strips to rotate, facilitating the upward movement of the biomass pellets, followed by rolling and tumbling. This improves the uniformity and effectiveness of heat dissipation. The first servo motor drives the vent pipe to rotate, further enhancing the uniformity of heat dissipation for the biomass pellets.

Detailed Implementation

[0026] The present invention will now be described in further detail with reference to the accompanying drawings.

[0027] Please see Figure 1-3 As shown, this embodiment provides a biomass pellet cooling and conveying device, including a tank 1, a guide cylinder 2 rotatably fitted inside the tank 1, a drive mechanism 3 for driving the guide cylinder 2 to rotate at one end of the tank 1, an auger blade 4 inside the guide cylinder 2, a plurality of protrusions 5 arranged circumferentially on the inner wall of the guide cylinder 2, an air outlet pipe 6 rotatably fitted inside the tank 1, a first servo motor 7 for driving the air outlet pipe 6 to rotate on the inner wall of the tank 1, a fan 8 on one side of the tank 1, the air outlet end of the fan 8 is attached to the end of the air outlet pipe 6 that extends out of the tank 1, and a plurality of air outlet holes are evenly distributed on the outer side of the air outlet pipe 6.

[0028] The fan 8 drives cold air through multiple air outlets on the air outlet pipe 6 inside the tank 1, directly blowing it onto the biomass pellets on the inner wall of the feed cylinder 2, which facilitates better heat dissipation for the biomass pellets. The drive mechanism 3 is activated to rotate the feed cylinder 2 and the auger blades 4, which in turn transport the biomass pellets within the feed cylinder 2. The feed cylinder 2 drives the convex strips 5 to rotate, which helps the biomass pellets rise and then roll and tumble, thus improving the uniformity and effectiveness of heat dissipation for the biomass pellets. The first servo motor 7 drives the air outlet pipe 6 to rotate, which further improves the uniformity of heat dissipation for the biomass pellets.

[0029] Please see Figure 2-3 As shown, in this embodiment, the outer side of the air outlet pipe 6 is provided with multiple stirring blades 9. There is a first distance between the outer side of the stirring blades 9 and the inner wall of the auger blades 4, which facilitates the rotation of the stirring blades 9 to agitate and turn the biomass particles, thereby improving the dispersion effect of the biomass particles and the heat dissipation effect of the biomass particles.

[0030] Please see Figure 2 As shown, the inner wall of the tank 1 in this embodiment is provided with two first bearings 10, and the guide cylinder 2 is fixed in the two first bearings 10, so as to improve the stability of the rotation of the guide cylinder 2 through the first bearings 10.

[0031] Please see Figure 1-2 As shown, the drive mechanism 3 in this embodiment includes a second servo motor 301 located on the outside of the tank body 1, a gear 302 located at one end of the output shaft of the second servo motor 301 extending into the tank body 1, and an external gear ring 303 fixedly sleeved on the guide cylinder 2. The gear 302 meshes with the external gear ring 303, which facilitates the second servo motor 301 to drive the gear 302 to drive the external gear ring 303, the guide cylinder 2, and the auger blades 4 to rotate.

[0032] Please see Figure 2 As shown, the tank body 1 in this embodiment is provided with mounting holes on both sides. The mounting holes are equipped with second bearings. The air outlet pipe 6 is fixed in the two second bearings, which facilitates the improvement of the rotation stability of the air outlet pipe 6 through the second bearings and improves the stability of the air outlet pipe 6 in contact and communication with the air outlet end of the blower 8.

[0033] Please see Figure 2-3 As shown, in this embodiment, the first end of the tank body 1 is provided with a feed hopper 11, which is connected to the guide cylinder 2, so that the biomass pellets can enter the guide cylinder 2 through the feed hopper 11. The second end of the tank body 1 is provided with a discharge port 12, which is connected to the guide cylinder 2. The height of the bottom surface of the inner wall of the discharge port 12 gradually decreases from the end near the guide cylinder 2 to the end away from the guide cylinder 2, so that the cooled biomass pellets can be discharged through the discharge port 12. The second end of the tank body 1 is connected to an air valve 13, which is connected to the guide cylinder 2, so that the hot air in the upper part of the guide cylinder 2 can be discharged through the air valve 13. The lower part of the tank body 1 is provided with two bases 14. The height of the tank body 1 and the guide cylinder 2 gradually decreases from the end near the feed hopper 11 to the end near the discharge port 12, so that the guide cylinder 2 can tilt to discharge the biomass pellets through the discharge port 12.

[0034] Working principle: Biomass pellets enter the feed cylinder 2 through the feed hopper 11. The blower 8 drives cold air through multiple air outlets on the air outlet pipe 6 inside the tank 1, directly blowing it onto the biomass pellets on the inner wall of the feed cylinder 2, which facilitates better heat dissipation for the biomass pellets. The drive mechanism 3 is activated, and the second servo motor 301 drives the gear 302 to rotate the outer gear ring 303, the feed cylinder 2, and the auger blades 4, which in turn drive the biomass pellets to be conveyed in the feed cylinder 2. The feed cylinder 2 drives the convex strip 5 to rotate, which facilitates the rise of the biomass pellets, and then they roll and tumble, which facilitates better heat dissipation uniformity and heat dissipation effect. The first servo motor 7 drives the air outlet pipe 6 to rotate, which further improves the heat dissipation uniformity of the biomass pellets. The air outlet pipe 6 drives the stirring blades 9 to rotate, which facilitates the stirring and tumbling of the biomass pellets, improving the dispersion effect and heat dissipation effect of the biomass pellets.
