Description

Technical Field

[0001] This utility model relates to the field of centrifuge technology, and in particular to a centrifuge feeder. Background Technology

[0002] There are two main types of feeding methods for bottom-discharge centrifuges: one is feeding through the side wall of the feeding pipe, which can easily cause uneven grain distribution and thus cause the drum to shake; the other is feeding through a slanted disc, where the material is distributed evenly along the axial direction of the drum by a high-speed rotating, slanted disc.

[0003] The main structure of a swashplate feeder typically includes an inner cone and an outer cone. The outer cone is coaxially fitted around the inner cone, and the annular cavity formed between the outer and inner cones is the feeding chamber. Material enters the feeding chamber from the feed pipe and is then ejected outward from the discharge port. Existing swashplate feeders often suffer from insufficient roundness and concentricity of the inner and outer cones. At high speeds, material entering the feeder tends to wobble, affecting both the uniformity of material distribution and the normal operation of the equipment, thus reducing its production efficiency. Utility Model Content

[0004] In response to the shortcomings of existing inclined disc feeders, the applicant provides a centrifuge feeder with a reasonable structure, which improves the roundness and concentricity of the inner and outer cones, prevents the feeder from shaking, ensures material uniformity, and improves production efficiency.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A centrifuge feeder includes an outer cone and an inner cone. A feeding chamber and a discharge channel are provided between the outer cone and the inner cone. The discharge channel is connected to the feeding chamber. Several guide ribs are provided between the outer cone and the inner cone. The guide ribs divide the feeding chamber into several feeding zones, and each feeding zone is connected to the discharge channel.

[0007] As a further improvement to the above technical solution:

[0008] The surface of the guide rib is parallel to the axis of the fabric distributor.

[0009] One side of the guide rib is fixed to the outer cone, and the other side is fixed to the inner cone.

[0010] The guide rib plate has a curved surface that convexes in the direction of the material distributor's rotation.

[0011] The guide rib plate has an extension on the corresponding discharge channel, which is inserted into the discharge channel.

[0012] One side of the protrusion is fixed to the outer cone, and the other side is fixed to the inner cone.

[0013] The guide ribs are located in the lower middle part of the fabric cavity and are evenly distributed along the circumference.

[0014] The small end of the outer cone tube is turned inward along the radial direction to form a first inner flange, and the large end of the outer cone tube is turned outward along the radial direction to form a first outer flange; the outer cone tube, the first inner flange, and the first outer flange are integrally formed, and the outer cone tube is connected to the first inner flange and the first outer flange by rounded corners.

[0015] The inner cone has a second inner flange formed by turning the small end of the inner cone inward along the radial direction, and a second outer flange formed by turning the large end of the inner cone outward along the radial direction. The inner cone, the second inner flange, and the second outer flange are integrally formed, and the inner cone and the second inner flange and the second outer flange are respectively connected by rounded corners.

[0016] There is a gap between the first outer flange of the outer cone and the second outer flange of the inner cone, which forms the discharge channel.

[0017] The beneficial effects of this utility model are as follows:

[0018] This invention incorporates several guide ribs within the feeding chamber and discharge channel, supporting the outer and inner cones. On one hand, these guide ribs enhance the strength, roundness, and concentricity of the outer and inner cones, preventing the feeder from swaying during high-speed rotation, ensuring normal equipment operation, and improving production efficiency. On the other hand, the guide ribs divert and guide material to various feeding zones, resulting in more uniform material distribution and improved equipment stability, further enhancing production efficiency.

[0026] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0027] like Figure 1 , Figure 2 As shown, this utility model provides a feeder 10 for centrifuge feeding, including an outer cone 1 and an inner cone 2. The outer cone 1 is coaxially sleeved on the outside of the inner cone 2, and there is a cavity between the outer cone 1 and the inner cone 2, which forms a feeding cavity 4. There is a gap between the bottom sides of the outer cone 1 and the inner cone 2, which forms a discharge channel 5, which connects the feeding cavity 4 to the external environment of the feeder 10. Several guide ribs 3 are evenly spaced along the circumference in the lower middle part of the feeding cavity 4, which divide the lower middle part of the feeding cavity 4 into several feeding sections 41, each of which is connected to the discharge channel 5.

[0028] like Figure 1 As shown, the main body of the outer cone 1 is the outer cone cylinder 11, and the main body of the inner cone 2 is the inner cone cylinder 21. The small end of the outer cone cylinder 11 and the large end of the inner cone cylinder 21 are at the top and the large end is at the bottom. The taper of the outer cone cylinder 11 is smaller than the taper of the inner cone cylinder 21. A conical annular cavity with an opening area that gradually narrows from top to bottom is formed between the outer cone cylinder 11 and the inner cone cylinder 21. This cavity is part of the fabric cavity 4.

[0029] like Figure 1 As shown, the outer cone 11 of the outer cone body 1 has a first inner flange 12 formed by radially inwardly turning outward at its small end, and a first center hole 14 is formed inside the first inner flange 12. The outer cone 11 has a first outer flange 13 formed by radially outwardly turning outward at its large end. The outer cone 11, the first inner flange 12, and the first outer flange 13 are integrally formed, and the outer cone 11 is connected to the first inner flange 12 and the first outer flange 13 by rounded corners.

[0030] like Figure 1As shown, the inner cone 2 has a second inner flange 22 formed by radially inwardly turning outward at the small end of the inner cone 21, and a second center hole 24 is located inside the second inner flange 22. The inner cone 21 has a second outer flange 23 formed by radially outward turning outward at the large end of the inner cone 21. The inner cone 21, the second inner flange 22, and the second outer flange 23 are integrally formed, and the inner cone 21 is connected to the second inner flange 22 and the second outer flange 23 by rounded corners.

[0031] like Figure 1 As shown, there is a gap between the first outer flange 13 of the outer cone 1 and the second outer flange 23 of the inner cone 21, which forms the discharge channel 5.

[0032] like Figure 1 , Figure 2 As shown, the guide rib plate 3 is inserted between the outer cone 1 and the inner cone 2. The surface of the guide rib plate 3 is parallel to the axial direction of the distributor 10. One side of the guide rib plate 3 is fixed to the outer cone 1, and the other side is fixed to the inner cone 2. The surface of the guide rib plate 3 is an arc-shaped surface, convex in the direction of rotation of the distributor 10, which facilitates the guiding of materials toward the discharge channel 5. Figure 3 As shown, an outwardly extending portion 31 is provided on the guide rib plate 3, corresponding to the outwardly extending portion 5 of the discharge channel. The outwardly extending portion 31 is vertically inserted into the discharge channel 5. The top side of the outwardly extending portion 31 is fixed to the first outwardly extending edge 13 of the outer cone 1, and the bottom side is fixed to the second outwardly extending edge 23 of the inner cone 2. Several guide rib plates 3 are arranged in the material distribution cavity 4 and the discharge channel 5, supporting the outer cone 1 and the inner cone 2. On the one hand, they can improve the strength, roundness, and concentricity of the outer cone 1 and the inner cone 2, preventing the material distributor 10 from shaking when rotating at high speed, ensuring the normal operation of the equipment, and improving production efficiency. On the other hand, the guide rib plates 3 can divert and guide the material to each material distribution zone 41. The material is sprayed outward through the material distribution zone 41, resulting in higher uniformity of material distribution, which is more conducive to the stable operation of the equipment and improves the production efficiency of the equipment.

[0033] In actual use, the fabric feeder 10, such as Figure 4 As shown, the material distributor 10 is arranged at a certain angle. The feed pipe 20 extends vertically into the material distribution chamber 4 from the first central hole 14 of the outer cone 1. The material distributor 10 is connected to the drive motor 30. When feeding, the drive motor 30 drives the material distributor 10 to rotate at high speed. The material enters the material distribution chamber 4 from the feed pipe 20, is distributed to each material distribution zone 41, and is sprayed outward from the discharge channel 5 into the drum.

[0034] The above description is an explanation of the present utility model and not a limitation thereof. The present utility model can be modified in any form without departing from its spirit.
