Description

Technical Field

[0001] The utility model relates to a partition wheel discharger, in particular to a discharger suitable for discharging formulated powder materials. Background Art

[0002] The current partition wheel discharger includes a cylinder body and a partition wheel. The partition wheel is rotatably arranged in the inner cavity of the cylinder body. The outer periphery of the cylinder body is provided with a feed channel and a discharge port that are respectively communicated with the inner cavity. The feed channel is in the shape of a straight circular cylinder (as can be seen in Figure 10 shown, that is, any cross-section from the inlet end of the feed channel 111 to the position leading to the partition wheel 2 is a circular cross-section with equal diameter), and it is applicable to the discharging occasions of general granular materials.

[0003] In view of the above structure of the partition wheel discharger, when it is applied to the discharging occasion of formulated powder materials with a certain humidity and viscosity, since the formulated powder materials are always transported in the feed channel with a fixed shape and then enter the partition wheel, the formulated powder materials do not form lateral fluidity in the feed channel, and it is easy to form bridging and agglomeration effects, affecting the discharging uniformity of the partition wheel. Especially in the battery production industry, the battery materials involve formulated powder materials, and the dosing amount of the formulated powder materials requires high precision and also requires uniform spreading during dosing. The above partition wheel discharger cannot meet the discharging requirements of the formulated powder materials in the battery production industry. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a discharger suitable for discharging formulated powder materials with reasonable structure, reducing the possibility of powder agglomeration and improving discharging uniformity.

[0005] The purpose of the utility model is achieved as follows:

[0006] A discharger suitable for discharging formulated powder materials includes a cylinder body and a partition wheel. The partition wheel is rotatably arranged in the inner cavity of the cylinder body. The outer periphery of the cylinder body is provided with a feed channel and a discharge port that are respectively communicated with the inner cavity. A lofting deformation section is arranged between the outer end and the inner end of the feed channel, and one end of the lofting deformation section close to the partition wheel is deformed along the axis direction of the partition wheel.

[0007] The purpose of the utility model can also be solved by the following technical measures:

[0008] As a more specific solution, the cross-section of the lofting deformation section is elliptical to avoid forming dead corners in the feed channel.

[0009] As a further solution, the feed channel further includes a cylindrical section. The cylindrical section is connected to the outer end of the lofting deformation section. The two ends of the lofting deformation section are gradually transitioned. The major axis of the cross-section of the lofting deformation section gradually increases and the minor axis gradually shortens from the end close to the cylindrical section to the end close to the cylinder body.

[0010] As a further solution, a plurality of hoppers are evenly distributed on the outer periphery of the dividing wheel, and both ends of the hopper extend along the axis direction of the dividing wheel. The length of the major axis of the ellipse of the cross-section of the lofting deformation section is less than or equal to the length between both ends of the hopper, so as to prevent materials from falling into the gap between the end face of the dividing wheel and the inner cavity of the cylinder body.

[0011] As a further solution, the cross-sectional areas of any two cross-sections of the lofting deformation section are equal, or among any two cross-sections of the lofting deformation section, the cross-sectional area near the outer end is equal to or less than the cross-sectional area near the inner end, so as to prevent the situation of four-sided extrusion when the material passes through the lofting deformation section. The equality here means equal under rough measurement (for example, in millimeters, the difference in the long and short axis dimensions of the calculated area is within 1 millimeter).

[0012] As a further solution, the inner diameter of the cylindrical section is greater than the diameter of the dividing wheel.

[0013] As a further solution, the cross-sectional area of the lofting deformation section near one end of the dividing wheel is greater than or equal to the cross-sectional area of the cylindrical section, so as to ensure that when the material entering the feeding channel is input to the dividing wheel through the lofting deformation section, there is no simultaneous four-sided extrusion, preventing material agglomeration.

[0014] As a further solution, a first flange is provided at the outer end of the feeding channel, and a plurality of connecting holes are evenly distributed on the surface of the first flange.

[0015] As a further solution, the connecting holes are arc-shaped.

[0016] As a further solution, the discharge port is rectangular, and a discharge pipe is connected to the outer end of the discharge port, and a second flange is provided at the outer end of the discharge pipe.

[0017] As a further solution, the cylinder body is horizontally arranged, and the feeding channel and the discharge port are respectively distributed above and below the outer periphery of the cylinder body.

[0018] The beneficial effects of the present utility model are as follows:

[0019] In this unloader, the lofting deformation section of the feeding channel can improve the lateral fluidity of the materials inside it, thereby destroying the material bridging and agglomeration effects. Moreover, one end of the lofting deformation section close to the dividing wheel is elongated to form a deformation, which can better distribute the materials into the hoppers of the dividing wheel, solving the problem of uneven discharge of the formulated powder materials with a certain humidity and viscosity.

[0030] The present utility model will be further described below in conjunction with the drawings and embodiments:

[0031] Referring to Figures 1 to 7 as shown, a discharger suitable for discharging formulated powder includes a cylinder body 1 and a dividing wheel 2. The dividing wheel 2 is rotatably arranged in the inner cavity 11 of the cylinder body 1. The outer periphery of the cylinder body 1 is provided with a feed channel 111 and a discharge port 112 that are respectively communicated with the inner cavity 11. A lofting deformation section 13 is provided between the outer end and the inner end of the feed channel 111. One end of the lofting deformation section 13 close to the dividing wheel 2 deforms along the axis direction of the dividing wheel 2.

[0032] The cross-section of the lofting deformation section 13 is oval.

[0033] The feed channel 111 further includes a cylindrical section 12. The cylindrical section 12 is connected to the outer end of the lofting deformation section 13. The two ends of the lofting deformation section 13 are gradually transitioned. The major axis of the oval cross-section of one end of the lofting deformation section 13 close to the cylindrical section 12 to its end close to the cylinder body 1 gradually increases (as shown at P2 in Figure 5 ), and the minor axis gradually shortens (as shown at P1 in Figure 4 ).

[0034] A plurality of hoppers 21 are evenly distributed on the outer periphery of the partition wheel 2. Both ends of the hopper 21 extend along the axial direction of the partition wheel 2. The length of the major axis of the elliptical cross-section of the lofting deformation section 13 is less than or equal to the length between both ends of the hopper 21. As shown in Figure 9 the figure, the end of the major axis of the inner cross-section of the feed channel 111 is close to the end of the hopper 21.

[0035] The cross-sectional areas of any two cross-sections of the lofting deformation section 13 are equal.

[0036] The inner diameter d1 of the cylindrical section 12 is greater than the diameter d2 of the partition wheel 2.

[0037] The cross-sectional area of the lofting deformation section 13 near one end of the partition wheel 2 is greater than or equal to the cross-sectional area of the cylindrical section 12. Since the inner cross-section of the cylindrical section 12 is circular, while the inner cross-section of the lofting deformation section 13 is elliptical, and the area of the ellipse is not less than the area of the circle, the material entering the lofting deformation section 13 from the cylindrical section 12 is like being squeezed by the minor axis direction of the elliptical surface (as shown by the arrows T1 and T2 in Figure 8 ), and then deforms in the direction of the major axis of the ellipse (as shown by the arrows F1 and F2 in Figure 8 ), forming a transverse flow relationship, destroying its bridging and agglomeration effects (agglomeration), and being easily dispersed.

[0038] A first flange 121 is provided at the outer end of the feed channel 111, and a plurality of connection holes 122 are evenly distributed on the surface of the first flange 121.

[0039] The connection holes 122 are arc-shaped, facilitating angle adjustment between it and the external material conveying pipe.

[0040] The discharge port 112 is rectangular, and a discharge pipe 14 is connected to the outer end of the discharge port 112. A second flange 141 is provided at the outer end of the discharge pipe 14.

[0041] The cylinder body 1 is horizontally arranged, and the feed channel 111 and the discharge port 112 are respectively distributed above and below the outer periphery of the cylinder body 1.

[0042] Its working principle is: As shown in Figure 8 When the formulated powder material 10 containing a certain humidity and viscosity enters the feed channel 111, it is first conveyed through the cylindrical section 12, and then enters the lofting deformation section 13 for continuous conveyance. After entering the lofting deformation section 13, the formulated powder material 10 is squeezed by the minor axis direction of the elliptical surface (as shown by the arrows T1 and T2 in Figure 8 ), and then deforms in the direction of the major axis of the ellipse (as shown by the arrows F1 and F2 in Figure 8As shown by the arrows F1 and F2, a lateral flow relationship is formed to avoid the bridging and agglomeration effects of the formulated powder material 10. Finally, the formulated powder material 10 falls into the hopper 21 of the dividing wheel 2 from the most flattened position at the lower end of the lofting deformation section 13. Finally, the formulated powder material 10 is discharged from the discharge pipe 14 as the dividing wheel 2 rotates.

Those skilled in the art should understand that the present invention is not limited by the above embodiments.
