Description

Technical Field

[0001] The utility model relates to the technical field of material production, in particular to a transmission device for granular materials. Background Art

[0002] The transportation of granular materials by wind conveying is a common method in the material production process. The transmission devices currently used in the prior art are as follows: Figure 1 As shown, it includes a feeding barrel 3, which is a hollow cylindrical body, and has a first port 7 and a second port 8 at both ends of the axial direction, and a feeding through hole 9 whose axis is perpendicular to the axis of the feeding barrel 3 is provided on the side wall of the feeding barrel 3, and the fan 6 is arranged at a position corresponding to the first port 7, and the second port 8 corresponds to the external target position. When working, the granular material enters the inner cavity of the feeding barrel 3 through the feeding through hole 9, and at the same time, the fan 6 emits an airflow to drive the granular material entering the inner cavity of the feeding barrel 3 to move to the external target position through the second port 8. In this way, when the fan 6 conveys the airflow to the inner cavity of the feeding barrel 3, the air pressure inside the feeding barrel 3 is greater than the air pressure outside the feeding barrel 3, which will form resistance to the granular material moving through the feeding through hole 9 to the inner cavity of the feeding barrel 3, resulting in poor input of the granular material into the inner cavity of the feeding barrel 3, thereby affecting the conveying speed.

[0022] In order to make the purpose, technical solution and advantages of the utility model more clear, the following is a further detailed description of the particle material transmission device of the utility model in combination with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0023] like Figure 2As shown, a transmission device for granular materials is used to transport the granular materials produced by the material production equipment 1 into the silo 2. The transmission device for granular materials includes: a feeding cylinder 3, an end plate 4, a wind cylinder 5 and a fan 6. The feeding cylinder 3 is a hollow cylindrical body, and its two axial ends are respectively provided with a first port 7 and a second port 8. The end plate 4 is fixedly connected to the first port 7 to block the first port 7. A feeding through hole 9 is provided on the side wall of the feeding cylinder 3. The feeding cylinder 3 is horizontally arranged below the material production equipment 1, and the feeding through hole 9 corresponds to the material production equipment 1, so that the granular materials discharged from the material production equipment 1 can enter the feeding cylinder 3 through the feeding through hole 9, and the second port 8 corresponds to the silo 2, so that the granular materials in the feeding cylinder 3 can enter the silo 2 through the second port 8. The wind tube 5 is a hollow cylindrical body, and has an air inlet 10 and an air outlet 11 at its two axial ends respectively. The wind tube 5 is arranged inside the feeding tube 3, and its axis coincides with the axis of the feeding tube 3. A mounting through hole 12 whose axis coincides with the axis of the feeding tube 3 is arranged on the end plate 4. One end of the wind tube 5 having the air inlet 10 is tightly connected to the mounting through hole 12. The fan 6 is arranged at a position corresponding to the air inlet 10 to drive the air flow into the wind tube 5 from the air inlet 10 and discharge it from the air outlet 11. In the extension direction along the axis of the feeding tube 3, the minimum distance between the inner wall of the feed through hole 9 and the second port 8 is greater than the distance between the air outlet 11 and the second port 8.

[0024] In operation, when the fan 6 drives the airflow from the air inlet 10 into the inner cavity of the air cylinder 5 and is discharged from the air outlet 11, according to the Venturi principle, a vacuum negative pressure zone is formed in the annular area between the feed hole 9 and the air outlet 11 inside the feeding cylinder 3 and outside the air cylinder 5, so that the granular material discharged from the material production equipment 1 can smoothly enter the feeding cylinder 3 through the feed hole 9, and enter the silo 2 through the second port 8 driven by the airflow, which can improve the smoothness of the granular material entering the feeding cylinder 3 compared with the prior art, thereby ensuring the transmission speed. The fan 6 can be an axial flow fan but is not limited thereto.

[0025] Furthermore, polytetrafluoroethylene is applied on the inner wall of the feeding tube 3 and the outer wall of the air tube 5. This technical solution can prevent the granular material with high viscosity from adhering to the inner wall of the feeding tube 3 and the outer wall of the air tube 5, thereby ensuring the smooth transportation of the granular material with high viscosity.

[0026] As an implementation method, Figure 2 As shown in the figure, the inner cavity of the feeding cylinder 3 is cylindrical, and the outer contour of the air cylinder 5 and the inner cavity of the air cylinder 5 are both truncated cones that gradually taper from the air inlet 10 toward the air outlet 11. The cone angle of the outer contour of the air cylinder 5 and the inner cavity of the air cylinder 5 is α, and 10°≤α≤30°. Figure 1 As shown, the diameter of the air inlet 10 is D1, the diameter of the air outlet 11 is D2, and D1=3×D2. Among them, 50mm≤D2≤100mm, that is, 100mm≤D1≤300mm. At the same time, the inner diameter of the feeding cylinder 3 is D3, and D3=D1+50mm.

[0027] Specifically, Figure 2 As shown in FIG. 1 , the axial length of the air cylinder 5 is L, and 0.5m≤L≤1m. Also, in the extension direction along the axis of the feeding cylinder 3, the distance between the inner wall of the feeding hole 9 and the exhaust port 11 is H, 50mm≤H≤100mm.

[0028] The above-mentioned embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
