Description

Technical Field

[0001] This utility model relates to the technical field, specifically to a pressure roller vertical plate structure for a biomass pellet mill. Background Technology

[0002] With increasing emphasis on the environment, higher environmental protection requirements have been put forward for fuels. Biomass pellet fuel made from bamboo powder, wood powder, agricultural and forestry waste, and crop straw is becoming increasingly sought after by businesses. Biomass pellet machines are the main equipment for producing biomass fuel and have become the main research and development focus of major manufacturers.

[0003] Currently, the settings for the pressure rollers, cylinders, and ring dies in biomass pellet mills on the market are relatively outdated. The applicant's prior patent CN202320424597.7, "A Pressure Roller Adjustment Mechanism for a Horizontal Pellet Mill," provides a pressure roller structure and also demonstrates the matching vertical plate structure for the pressure roller of the horizontal pellet mill. However, during use, the applicant found that the material feeding efficiency of the pellet mill inner cylinder with this structure is poor, and it is easy to accumulate material, resulting in a high failure rate. Utility Model Content

[0004] In view of the existing technology, the purpose of this utility model is to provide a pressure roller vertical plate structure for a biomass pellet mill, which can make material feeding easier and smoother, and improve pelleting efficiency.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a pressure roller upright plate structure for a biomass pellet mill, wherein the pressure roller upright plate is provided with an outer cylinder, a screw feeding assembly and at least two eccentric pressure rollers, wherein the eccentric pressure rollers are located at the main shaft holes on the inner side of the outer cylinder pressure roller upright plate, the screw feeding assembly is fixed outside the feed inlet of the pressure roller upright plate, and the two main shaft holes are eccentric relative to the middle of the pressure roller upright plate and are arranged with a height difference in the vertical direction.

[0006] As a further feature of the above scheme, the feed inlet is offset to one side relative to the middle of the pressure roller upright plate and is located at the upper end of one side of the eccentric pressure roller.

[0007] As a further feature of the above scheme, one of the two eccentric pressure rollers is located near the bottom of the outer cylinder, and the other is located at a higher position. The ring mold that is matched with the outer cylinder drives the bottom material to rotate towards the eccentric pressure roller that is closer to the bottom.

[0008] As a further feature of the above scheme, a U-shaped guide plate is provided on the pressure roller plate relative to the feed inlet. The U-shaped guide plate is located below the feed inlet and extends upwards on both sides towards the two eccentric pressure rollers.

[0009] Beneficial effects: The biomass pellet mill of this utility model improves the structure of the pressure roller vertical plate by tilting the two sets of eccentric pressure rollers and offsetting the feed inlet to the center. Furthermore, the U-shaped guide plate directly guides the input material onto the pressure roller. The pressure roller has a large contact area with the raw material, reducing the problem of material accumulation, making it easier to discharge the pellet mill. The combination of the pressure roller and the ring die results in high pelleting efficiency and smoother equipment operation. Attached Figure Description

[0017] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, where there is no conflict, the embodiments and features described in these embodiments can be combined with each other.

[0018] like Figure 1-5 The diagram shows a pressure roller plate structure for a biomass pellet mill. The pressure roller plate 2 is provided with an outer cylinder 5, a screw feeding assembly 6, and at least two eccentric pressure rollers 7. The eccentric pressure rollers 7 are located at the main shaft holes 4 on the inner side of the outer cylinder 5 on the pressure roller plate 2. The screw feeding assembly 6 is fixed outside the feed inlet 3 of the pressure roller plate 2. The two main shaft holes 4 are eccentric relative to the middle of the pressure roller plate 2 and are arranged with a height difference in the vertical direction.

[0019] As a further feature of the above scheme, the feed port 3 is offset to one side relative to the middle of the pressure roller upright plate 2, and is located on the upper end of the eccentric pressure roller 7 on one side.

[0020] As a further configuration of the above scheme, one of the two eccentric pressure rollers 7 is located near the bottom of the outer cylinder 5, and the other is located at a higher position. The ring mold 9 provided with the outer cylinder 5 drives the bottom material to rotate towards the eccentric pressure roller 7 near the bottom.

[0021] As a further feature of the above scheme, a U-shaped guide plate 21 is provided on the pressure roller plate 2 relative to the feed inlet 3. The U-shaped guide plate 21 is located below the feed inlet 3 and extends to the top of the two eccentric pressure rollers 7 on both sides. The U-shaped guide plate 21 prevents the material from the feed inlet 3 from falling directly into the bottom of the ring die 9. The material is pushed to both sides by the screw feeding assembly 6, which reduces the problem of material accumulation.

[0022] like Figure 6 The existing technology shows the structure and positional relationship of the pressure roller plate 2 and the eccentric pressure roller 7. In this solution, the eccentric pressure roller 7 is very prone to material accumulation at the bottom. Excessive material accumulation can easily cause equipment malfunction.

[0023] refer to Figure 1-5 The device structure shown in this embodiment improves the pressure roller plate 2. When the device is running, the material is clamped and pressed by the cooperation of the ring die 9 and the eccentric pressure roller 7, and the material is forced to be squeezed out from the inner wall hole of the ring die 9 to form granules. Compared with the prior art, when the device in this embodiment is running, the raw material is guided by the U-shaped guide plate 21 and the raw material is quickly pressed out and consumed. The stroke of the falling material driven by the ring die 9 is shorter. The material is more easily processed by the eccentric pressure roller 7 near the bottom when the ring die 9 is rotated. The material accumulated inside is also consumed quickly, so it is not easy for material accumulation problems to occur.

[0024] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of this utility model and its equivalents, this utility model also intends to include these modifications and variations.
