Description

Technical Field

[0001] This utility model relates to the field of pellet mill technology, and in particular to a pellet mill discharge mechanism. Background Technology

[0002] Biomass pellets are a common form of biomass energy, typically made from waste crop straw, sawdust, and other biomass materials through processes such as crushing, pressing, and molding. They can be used to replace traditional fossil fuels and have advantages such as being environmentally friendly and renewable, thus having broad application prospects in the energy field.

[0003] The granules produced by existing pellet mills contain a lot of dust. When the granules are discharged from the discharge port of the pellet mill, the dust in the granules is easily blown away, causing pollution and health risks to the working environment and operators. At the same time, the dust adhering to the surface of the granules reduces the appearance and quality of the granules. Utility Model Content

This addresses the technical problems in the prior art where the pellet material after being pressed by the pellet mill contains a lot of dust, and when the pellet material is discharged from the discharge port of the pellet mill, the dust in the pellet material is easily blown away, causing pollution and health risks to the working environment and operators. At the same time, the surface of the pellet material is covered with dust, which reduces the appearance and quality of the pellet material.

Detailed Implementation

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0016] This utility model embodiment provides a discharge mechanism for a pellet mill, such as... Figure 1As shown, the system includes a discharge box 1, with a feeding plate 2 inclined inside the discharge box 1. A feeding pipe 3 is located above the upper end of the feeding plate 2, and the upper end of the feeding pipe 3 extends out from the inside of the discharge box 1 through the top plate of the discharge box 1. A discharge port 11 is located at the bottom of the discharge box 1. A blower 4 is installed in the discharge box 1 below the feeding pipe 3. An air intake 12 is located in the discharge box 1 opposite to the blowing direction of the blower 4. The air intake 12 is connected to a dust collector 5. The granular material discharged from the pellet mill can fall onto the feeding plate 2 through the feeding pipe 3. The granular material falling onto the feeding plate 2 can roll off the feeding plate 2 and be discharged through the discharge port 11. At the same time, the blower 4 can blow away the dust in the granular material. The dust can be blown into the air intake 12 and collected by the dust collector 5. This can avoid the dust in the granular material from causing pollution and health risks to the working environment and operators. It can also prevent dust from adhering to the surface of the granular material, ensuring that the appearance and quality of the granular material meet the requirements.

[0017] It should be noted that the bottom of the discharge box 1 is provided with a slope 13, and the discharge port 11 is located at the lower position of the slope 13, which can facilitate the discharge of granular materials rolling down from the discharge plate 2 from the discharge port 11.

[0018] In this embodiment, the angle between the feeding plate 2 and the horizontal plane is 30-45 degrees. At the same time, a vibration motor can also be installed on the feeding plate 2. The vibration motor can make the feeding plate 2 vibrate, which is beneficial for the granular material to roll off the feeding plate 2 and avoid the accumulation of granular material on the feeding plate 2.

[0019] In this embodiment, the feed pipe 3 is equipped with a control valve 6 for controlling the opening and closing of the internal channel of the feed pipe 3, such as... Figure 2 As shown, the control valve 6 includes a baffle 61, which is connected to a drive assembly 62 for rotating the baffle 61 to control the opening or closing of the bottom opening of the feed pipe 3. Simultaneously, several detection probes 63 are evenly spaced from top to bottom on the side wall of the feed pipe 3. The detection probes 63 are infrared sensors or laser sensors. The detection probes 63 and the drive assembly 62 are electrically connected to a controller 64. The detection probes 63 are used to detect the amount of granular material inside the feed pipe 3. The controller 64 receives the detection signals from the detection probes 63 and controls the drive assembly 62 to adjust the rotation angle of the baffle 61 based on the detected signals, thereby controlling the opening of the bottom opening of the feed pipe 3. This controls the feeding speed of the granular material. When there is a large amount of granular material inside the feed pipe 3, the opening of the bottom opening of the feed pipe 3 can be increased to increase the feeding speed and prevent the accumulation of granular material on the pellet mill. When there is a small amount of granular material inside the feed pipe 3, the opening of the bottom opening of the feed pipe 3 can be decreased to reduce the feeding speed and improve the dust removal effect from the granular material.

[0020] As for the drive component 62, it only needs to be able to drive the baffle 61 to rotate. Therefore, it is not limited to a specific structure. For example, in some embodiments, the drive component 62 is one of an electric motor, a hydraulic motor, or a pneumatic motor.

[0021] In this embodiment, a rotating shaft 611 is provided on one side of the baffle 61. The rotating shaft 611 is rotatably installed on the bottom opening side of the feed tube 3. The driving assembly 62 includes a rotating plate 621. The rotating plate 621 has a strip-shaped sliding hole 6211 along its length. A slider 622 is movably provided inside the strip-shaped sliding hole 6211. The slider 622 is connected to a lifting device 623 for driving the slider 622 to move up and down. The lifting device 623 is one of a cylinder, a hydraulic cylinder, or an electric telescopic rod. The slider 622 can be driven to move up and down through the lifting device 623. At the same time, the slider 622 can slide inside the strip-shaped sliding hole 6211. The slider 622 can drive the rotating plate 621 to rotate, thereby driving the baffle 61 to rotate.

[0022] Specific principle: During use, the feed pipe 3 is connected to the discharge port of the pellet mill. The pellets discharged from the pellet mill can fall onto the feed plate 2 through the feed pipe 3. The pellets on the feed plate 2 can roll down and be discharged through the discharge port 11. At the same time, the blower 4 can blow away the dust in the pellets. The dust can be blown into the air intake 12 and collected by the vacuum cleaner 5. This can avoid the dust in the pellets from causing pollution and health risks to the working environment and operators. It can also prevent dust from adhering to the surface of the pellets, ensuring that the appearance and quality of the pellets meet the requirements. At the same time, the detection probe 63 is used to detect the amount of pellets inside the feed pipe 3. The controller 64 receives the detection signal from the detection probe 63 and controls the drive component 62 to adjust the rotation angle of the baffle 61 through the detected signal, so as to control the opening of the bottom opening of the feed pipe 3. This controls the feeding speed of the granular material. When there is a lot of granular material inside the feed pipe 3, the opening of the bottom opening of the feed pipe 3 can be increased to increase the feeding speed of the granular material and avoid the accumulation of granular material on the pellet mill. When there is a little granular material inside the feed pipe 3, the opening of the bottom opening of the feed pipe 3 can be decreased to reduce the feeding speed of the granular material and improve the dust removal effect in the granular material.

[0023] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
