Description

Technical Field

[0001] The utility model relates to the technical field of horizontal screw centrifuges, in particular to a horizontal screw centrifuge. Background Art

[0002] The horizontal screw centrifuge is a sedimentation equipment with horizontal spiral unloading and continuous operation. The working principle of this type of centrifuge is: the drum and the spiral rotate at high speed in the same direction with a certain differential speed. The material is continuously introduced into the inner cylinder of the feeding spiral from the feed pipe, and enters the drum after acceleration. Under the action of the centrifugal field, the heavier solid phase is deposited on the drum wall to form a sediment layer. The feeding spiral continuously pushes the deposited solid phase to the cone end of the drum and is discharged from the machine through the slag discharge port. The lighter liquid phase forms an inner liquid ring, which continuously overflows the drum from the overflow port at the large end of the drum and is discharged from the machine through the liquid discharge port.

[0003] The supporting legs of traditional horizontal screw centrifuges are mostly fixed, so that the entire device is in a static state when in use. At this time, the slag flows to the slag discharge port. Since it is in a wet state after being separated from the liquid, the wet slag can easily block the slag discharge port when it accumulates together. In addition, the supporting legs of traditional horizontal screw centrifuges are mostly fixed to the entire device, making it impossible to fine-tune the height of the device. If the supporting legs are damaged, it is more troublesome to disassemble and repair them because they are not fixed. Utility Model Content

In addition, the supporting feet of traditional horizontal screw centrifuges are mostly fixed together with the entire device, and the height of the device cannot be fine-tuned. If the supporting feet are damaged, it is troublesome to disassemble and repair them because they are unchanged. A horizontal screw centrifuge is provided.

When fine-tuning the height of the device through the provided fixed rod, telescopic support leg, vibration chamber, vibration slider, fixing nut, vibration spring and adjustment hole, slide the telescopic support leg outward so that the middle of the vibration slider provided on the upper inner side of the telescopic support leg slides to the position of the adjustment hole on the corresponding position opened on the fixed rod, and then pass the fixing nut through the adjustment hole, the middle of the vibration slider and the adjustment hole on the other side of the fixed rod in sequence, and then seal one end of the fixing nut with a nut, and fix the fixing rod and the telescopic support leg together to fix the adjusted height of the telescopic support leg. When the device is started, the vibration force generated is transmitted to the fixed rod When the device is raised, the vibration slider connected by the fixing nut and the fixing rod will slide up and down in the vibration chamber. The vibration slider sliding up and down will squeeze a vibration spring provided at both ends of the inner side of the vibration chamber. The rebound force of the vibration spring will drive the vibration slider to slide up and down, thereby driving the fixing rod provided on the outside of the fixing nut to vibrate up and down along the telescopic support leg through the fixing nut engaged with the vibration slider, thereby driving the device to vibrate.

When the slag is thrown out through one end of the drum, the flowing hot air flow will preliminarily dry the slag to prevent the slag from being adhered together due to heavy moisture. The dried slag falls into the slag discharge port under the action of gravity and is discharged through the slag discharge port. When the outer surface of the drum is cleaned, The push-pull rod is pushed downward, and the first scraper and the second scraper fixedly connected at the left and right ends of the bottom of the push-pull rod are respectively stuck on the outer surfaces of the left and right ends of the drum in turn.
