Description

Technical Field

[0001] This utility model relates to the field of horizontal screw centrifuge technology, and more specifically, to a solid-liquid separation device for a high-speed horizontal screw centrifuge. Background Technology

[0002] A horizontal screw centrifuge is a highly efficient centrifugal separation device. Its working principle involves a drum and a screw rotating at a certain differential speed in the same direction at high speed. Material is continuously introduced into the inner cylinder of the conveying screw through the feed pipe, accelerated, and then enters the drum. Under the action of centrifugal force, the heavier solids deposit on the drum wall, forming a sludge layer. The conveying screw continuously pushes the deposited solids to the conical end of the drum, where they are discharged from the machine through the sludge discharge port. The lighter liquids form an inner liquid ring, continuously overflowing from the large end of the drum through the overflow port and discharged from the machine through the liquid discharge port.

[0003] When using a horizontal screw centrifuge, the centrifuged material is often discharged directly, which can easily clog the discharge port, affecting the normal operation and efficiency of the centrifuge.

These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0025] According to an embodiment of the present invention, a solid-liquid separation device for a high-speed horizontal screw centrifuge is provided.

[0026] Example 1:

[0027] like Figure 1-5 As shown, the high-speed horizontal screw centrifuge solid-liquid separation device according to an embodiment of the present utility model includes a support base 1 and a conveying screw cylinder 2. The conveying screw cylinder 2 is located at the top of the support base 1. One end of the conveying screw cylinder 2 is provided with a feed inlet 3. The top of the support base 1 is provided with a fixed cover 4 covering the conveying screw cylinder 2. The bottom end of the conveying screw cylinder 2 is provided with a discharge mechanism.

[0028] The discharge mechanism includes a discharge shell 5, which is a cavity structure with openings at both ends, and an inclined filter frame 6 is provided inside the discharge shell 5.

[0029] Example 2:

[0030] like Figure 1-5As shown, the discharge shell 5 is located below the filter frame 6 and has an inclined connecting frame 7. The left end of the connecting frame 7 has a connecting shaft 8 that is movably connected to the discharge shell 5. The connecting frame 7 has a spring 9 that is connected to the filter frame 6. The right end of the connecting frame 7 has a sliding hole 10. The sliding hole 10 has a matching sliding shaft 11. One end of the sliding shaft 11 has a vertically arranged movable column 12. The movable column 12 and the sliding shaft 11 have an L-shaped structure. One side of the movable column 12 has a toothed plate 13. The discharge shell 5 has a toothed disc 14 that meshes with the toothed plate 13.

[0031] Example 3:

[0032] like Figure 1-5 As shown, a horizontally arranged connecting rod 15 is provided on the other side of the gear disk 14. A fixed shaft 16 connected to the discharge shell 5 is movably connected to the connection between the connecting rod 15 and the gear disk 14. A stroke hole 17 is provided on the connecting rod 15. A matching sliding column 18 is provided in the stroke hole 17. A turntable 19 connected to one end of the sliding column 18 is provided in the discharge shell 5.

[0033] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0034] In practical applications, materials are conveyed through the feed inlet 3, and then the conveying screw drum 2 rotates to centrifuge the materials. The centrifuged materials are then discharged through the discharge shell 5 at the discharge port. The motor is started to drive the turntable 19 to rotate, and the turntable 19 drives the sliding column 18 to rotate eccentrically. During the movement, the sliding column 18 reciprocates in the stroke hole 17, causing the connecting rod 15 to drive the gear plate 14 to reciprocate around the fixed shaft 16. The gear plate 14 and the gear plate 13 reciprocate in opposite directions, thereby driving the movable column 12 to reciprocate in the up and down direction. The movable column 12 drives the sliding shaft 11 to move in the sliding hole 10, causing the connecting frame 7 to swing back and forth around the connecting shaft 8. This causes the connecting frame 7 to vibrate the filter frame 6 through the spring 9, thereby improving the filtration effect of the filter frame 6.

[0035] In summary, by means of the above-mentioned technical solution of this utility model, the filter frame 6 is tilted by setting the discharge mechanism, which can better achieve solid-liquid separation in light liquid; and the movable column 12 can drive the connecting frame 7 to swing back and forth around the connecting shaft 8 as the axis, so that the connecting frame 7 drives the filter frame 6 to vibrate through the spring 9, thereby improving the filtration effect of the filter frame 6 and preventing the outlet from being blocked.
