Description

Technical Field

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

[0002] Currently, horizontal screw centrifuges are generally used for solid-liquid separation.

[0003] In existing technologies, horizontal centrifuges utilize the centrifugal force generated by a high-speed rotating drum to trap solid particles in the suspension within the drum and automatically discharge them to the drain and slag outlets set on the drum under the action of force. However, vibration occurs during operation and cannot be adjusted. For example, in published document CN215694873U, the vibration generated during operation is transmitted downward to a buffer mechanism, thereby solving the problem of vibration affecting the operation of the device. Since the drum is fixedly set in a horizontal state and the angle cannot be adjusted, poor separation effect and sludge accumulation and blockage of the conveying pipeline will occur.

[0004] Therefore, the applicant hereby submits this application. Utility Model Content

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments:

[0024] See Figures 1-6An adjustable support structure and centrifuge are disclosed, including a centrifuge and a base 1. The centrifuge includes a housing 2, and a rotating drum 3 is arranged inside the housing 2. The rotating drum 3 is the core component of the centrifuge. It achieves the separation of solid-liquid, liquid-liquid and solid-liquid-liquid mixtures by centrifugal force generated by high-speed rotation. A spiral pusher 17 for conveying sludge and providing a drainage channel is arranged inside the rotating drum 3. The spiral pusher 17 is usually composed of spiral blades and an inner cylinder and is stably installed inside the rotating drum 3 by a shaft.

[0025] One end of the drum 3 is connected to the main motor 4, which is connected to the output shaft of the main motor 4 via the transmission belt 20. The main function of the main motor 4 is to drive the drum 3 to rotate. When the main motor 4 starts, it will drive the drum 3 to rotate at high speed, thereby generating a strong centrifugal force. A gearbox is set between the auxiliary motor 5 and the drum 3. The auxiliary motor 5 is responsible for controlling the input shaft speed of the differential, and transmitting the torque to the screw feeder 17 at a specific speed ratio through the differential.

[0026] Specifically, since the drum 3 is fixed in a horizontal position and the angle cannot be adjusted, the separation effect will be poor, and the sediment will accumulate and block the conveying pipe. The base 1 is equipped with a fixing part 9 and a hydraulic cylinder 6. The auxiliary motor 5 is located on the fixing part. The piston rod 7 of the hydraulic cylinder 6 is equipped with a base plate 8. The main motor 4 is located on the base plate 8. In order to prevent the centrifuge from shifting under high speed rotation, the base plate 8 can be fixed to the end of the piston rod 7 of the hydraulic cylinder 6. The rise or fall of the piston rod 7 of the hydraulic cylinder 6 can drive the angle adjustment of one side of the centrifuge. The main motor 4 can be fixedly installed on the base plate 8. After the centrifuge is placed on the fixing part 9 and the base plate 8, the centrifuge is in a horizontal position.

[0027] To enable solid-liquid separation, a feed inlet 22 is provided at the front end of the drum 3. The main function of the feed inlet 22 is to introduce the material into the centrifuge for separation. A liquid discharge port 18 and a slag discharge port 19 are provided at the bottom of the drum 3. The slag discharge port 19 is located at the front end of the screw conveyor 17, close to the feed inlet 22. The liquid discharge port 18 is located at the tail end of the screw conveyor 17. The liquid discharge port 22 is located at the center or tail end of the centrifuge and is used to discharge the separated liquid. The slag discharge port 19 is located on the periphery of the centrifuge and is used to discharge the solid.

[0028] To improve the stability of the centrifuge during high-speed rotation, rods 10 are installed on the centrifuge casing 2, as shown in the figure. Rods 10 are installed on both sides of the casing 2. One end of each rod 10 is fixed to the casing 2, and the other end is rotatably connected to a connecting block 11. A support block 12 is installed on the connecting block 11. The connecting block 11 and the support block 12 can be fixed together by screws or welding. A groove 21, which is an arc-shaped groove, is provided below the support block 12. A protrusion 13 is provided at the bottom of the support block 12, which slides on the arc-shaped groove. The support block 12 slides on the arc-shaped groove by adjusting the angle of the centrifuge through the rising or falling of the piston rod 7 of the hydraulic cylinder 6. The support block 12 ensures the centrifuge remains stable during high-speed rotation. A linear module 14 is provided on one side of the tank 21. The linear module 14 includes a slider 15, on which a cylinder 16 is fixed. When the support block 12 changes position, the linear module 14 can be operated remotely to adjust the slider 15 to the front of the support block 14. The piston rod of the cylinder 16 then contacts the support block 12, clamping the support block and achieving stability. This improves the stability of the centrifuge during operation and reduces vibration. The adjustment and movement of the linear module 14 can be adapted to the length of the arc-shaped tank, and the contact height of the piston rod of the cylinder 16 can be adapted to the adjustment height of the support block 12.

[0029] Working principle: The centrifuge initially operates in a horizontal position. Since the centrifuge is fixed in a horizontal position, the angle cannot be adjusted, resulting in poor separation effect. When the oil cylinder 6 starts to work, its piston rod 7 rises or falls, which drives the angle adjustment of one side of the centrifuge. The support block 12 also adjusts its angle accordingly. The linear module 14 drives the cylinder 16 to adjust its position according to the position of the support block 12. The piston rod of the cylinder 16 abuts against the support block 12 and clamps it, which solves the problem of centrifuge angle adjustment and the stability of the support block 12.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
