Description

Technical Field

[0001] This utility model relates to the field of centrifuge accessories technology, specifically a high-efficiency separation and unloading mechanism for a disc centrifuge. Background Technology

[0002] In the field of centrifuge technology, disc centrifuges, as a highly efficient solid-liquid separation device, are widely used in various industries such as chemical, pharmaceutical, and food. However, traditional disc centrifuges often have some shortcomings in the separation and unloading process, especially when handling centrifuge drums of different diameters, where their adaptability and convenience are limited.

[0003] Traditional disc centrifuges typically use a fixed connection structure to connect the centrifuge drum and the separation mechanism. This structure is often difficult to adapt to centrifuge drums of different diameters, leading to frequent replacement or adjustment of connecting parts during use. This not only increases operational difficulty but also reduces work efficiency. Furthermore, traditional separation mechanisms often suffer from inefficiency during unloading, with filter material and residue easily mixing together, making effective separation and diversion difficult. Therefore, we propose a high-efficiency separation and unloading mechanism for disc centrifuges. Utility Model Content

[0005] The technical solution of this utility model is:

[0006] A high-efficiency separation and unloading mechanism for a disc centrifuge includes an outer cylinder and an inner cylinder located inside the outer cylinder. The bottom of the outer cylinder has an integrally formed bent tube, and the bottom of the inner cylinder has an integrally formed extension tube. The extension tube passes through the bent tube and extends to below the bent tube at its bottom. The diameter of the extension tube is smaller than that of the bent tube. A connecting cloth is installed at the top of the inner cylinder. The connecting cloth is frustum-shaped. A connecting mechanism is installed at the top of the inner cylinder. The bottom of the connecting mechanism is fixedly connected to the top of the inner ring wall of the inner cylinder, and the top of the connecting mechanism is connected to the top of the connecting cloth.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 This utility model provides a technical solution:

[0024] A high-efficiency separation and unloading mechanism for a disc centrifuge includes an outer cylinder 1 and an inner cylinder 4 located inside the outer cylinder 1. A bent tube 3 is integrally formed at the bottom of the outer cylinder 1, and an extension tube 40 is integrally formed at the bottom of the inner cylinder 4. The extension tube 40 passes through the bent tube 3 and extends below the bent tube 3. The diameter of the extension tube 40 is smaller than that of the bent tube 3. A connecting cloth 5 is installed at the top of the inner cylinder 4. The connecting cloth 5 is frustoconical in shape. A connecting mechanism 6 is installed at the top of the inner cylinder 4. The bottom of the connecting mechanism 6 is fixedly connected to the top of the inner ring wall of the inner cylinder 4, and the top of the connecting mechanism 6 is connected to the top of the connecting cloth 5. The connecting mechanism 6 is used to adjust the diameter of the top of the connecting cloth 5. It should be noted that the connecting cloth 5 in this invention is made of elastic fabric. The connecting mechanism 6 can adjust the diameter of the top of the connecting cloth 5, thus adapting to different centrifuge cylinder diameters, increasing adaptability and convenience during use. Furthermore, the inner cylinder 4 and outer cylinder 1 can effectively separate and divert filter materials and residues, increasing efficiency during unloading.

[0025] In a preferred embodiment, a top fixing ring 2 is coaxially welded to the top of the outer cylinder 1, and the top fixing ring 2 has several equally spaced fixing holes. The top connecting ring is used to connect this device to the centrifuge.

[0026] In a preferred embodiment, the connecting mechanism 6 includes a bottom center disk 60, on which at least two connecting rods 61 are welded. A plurality of connecting rods 61 are arranged in a circular array, with one end of each connecting rod 61 away from the bottom center disk 60 fixedly connected to the inner wall of the inner cylinder 4. The bottom center disk 60 and the connecting rods 61 connect the connecting mechanism 6 to the inner wall of the inner cylinder 4, thereby providing stable support for the entire connecting mechanism 6.

[0027] In a preferred embodiment, a first hydraulic cylinder 62 is fixedly mounted on the top of the bottom center plate 60. A top center plate 63 is fixedly mounted on the top of the piston rod of the first hydraulic cylinder 62. Four second hydraulic cylinders 64 are fixedly mounted on the outer ring wall of the top center plate 63 in a circular array. Each second hydraulic cylinder 64 has an arc-shaped clamping block 65 fixedly mounted on its piston rod, which is connected to the connecting cloth 5. The height of the top center plate 63 can be adjusted by the first hydraulic cylinder 62, thereby adjusting the height of the entire connecting mechanism 6. The position of the arc-shaped clamping block 65 can be adjusted by the second hydraulic cylinders 64, thereby adjusting the top diameter of the connecting cloth 5 connected to the arc-shaped clamping block 65.

[0028] In a preferred embodiment, the bottom of the arc-shaped clamping block 65 has a clamping opening 650 for connecting with the connecting cloth 5, and an anti-slip pad is installed on the inner ring wall of the arc-shaped clamping block 65. The anti-slip pad is used to increase the tightness of the connection between the arc-shaped clamping block 65 and the centrifuge cylinder. It should be noted that since the centrifuge cylinder usually needs to rotate at high speed, a bearing needs to be installed between the inner wall of the arc-shaped clamping block 65 and the outer wall of the inner cylinder 4 to ensure that the centrifuge cylinder can rotate freely.

[0029] In a preferred embodiment, the connecting fabric 5 has an extension block 50 integrally formed between two adjacent arc-shaped clamping blocks 65, and both ends of the extension block 50 are fixedly connected to the arc-shaped connecting blocks located on both sides thereon. The extension block 50 is provided to increase the sealing of the connection between the connecting fabric 5 and the arc-shaped clamping blocks 65.

[0030] In a preferred embodiment, the top of the arc-shaped clamping block 65 protrudes above the piston rod of the second hydraulic cylinder 64. This ensures that the arc-shaped clamping block 65 has sufficient space to connect with the outer wall of the centrifuge drum.

[0031] In a preferred embodiment, when the piston rods of the first hydraulic cylinder 62 and the second hydraulic cylinder 64 are both at their original lengths, the connecting cloth 5 and the extension block 50 are both in an unstretched state. This ensures that the connecting cloth 5 and the extension block 50 can be restored when not in use, preventing them from losing some elasticity due to prolonged stretching.

[0032] When using the high-efficiency separation and unloading mechanism of the disc centrifuge of this utility model:

[0033] First, the entire mechanism is securely connected to the centrifuge via the top fixing ring 2 at the top of the outer cylinder 1 and its fixing holes. This step ensures the stability and safety of the mechanism during subsequent operation.

[0034] Next, based on the diameter of the centrifuge drum, the top diameter of the connecting cloth 5 is adjusted via the connecting mechanism 6. Specifically, the first hydraulic cylinder 62 is activated to adjust the height of the top center plate 63, thus initially setting the overall height of the connecting mechanism 6. Subsequently, four second hydraulic cylinders 64 are activated, driving the four arc-shaped clamping blocks 65 to move radially until they are tightly fitted against the outer wall of the centrifuge drum. The clamping jaws 650 at the bottom of the arc-shaped clamping blocks 65 and the anti-slip pads on the inner ring wall ensure a tight and stable connection with the centrifuge drum, while the presence of bearings ensures that the centrifuge drum can rotate freely without obstruction.

[0035] After the centrifuge starts working, the synergistic action of the inner cylinder 4 and the outer cylinder 1 achieves effective separation of the filtered material and the residue. The extension tube 40 at the bottom of the inner cylinder 4 passes through the bent tube 3 at the bottom of the outer cylinder 1 and extends below it, which can effectively separate the filtered material from the residue.

[0036] In summary, the high-efficiency separation and unloading mechanism of this invention, through the flexible adjustment of the connecting mechanism 6, the separation design of the inner cylinder 4 and the outer cylinder 1, and the ingenious cooperation of the extension tube 40 and the bent tube 3, achieves efficient and stable separation and unloading functions, providing strong support for the application of centrifuges.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
