Abstract
The utility model provides a spiral shell centrifuge inlet pipe anti-sticking blocks up device crouches, includes inlet pipe, main shaft and frame, and the inlet pipe is fixed in the frame, and the inlet pipe is installed in the hole of main shaft feed end through preventing stifled cover, prevent that the hole of preventing stifled cover is the screw hole, and its right-hand member is tubaeform. The feeding pipe is fixed on the frame and is arranged in the inner hole of the main shaft through the anti-blocking sleeve, so that in the working process, the solid-liquid mixture in the feeding cavity can continuously permeate between the feeding pipe and the anti-blocking sleeve, the anti-blocking sleeve rotates at a high speed along with the main shaft, and the solid-liquid mixture permeating between the feeding pipe and the anti-blocking sleeve is continuously pushed to the feeding cavity, the solid-liquid mixture can be effectively prevented from entering between the anti-blocking sleeve and the feeding pipe, the friction of solid particles in the solid-liquid mixture on the feeding pipe is reduced, and the blocking phenomenon between the feeding pipe. Practical use verifies that the centrifuge has smooth feeding, no blockage and difficult abrasion of the feeding pipe in the working process.
Description
Technical field
The utility model relates to a kind of horizontal screw centrifuge, relates in particular to the feed arrangement of horizontal screw centrifuge.
Background technology
Horizontal screw centrifuge is a kind of totally-enclosed equipment that can carry out Separation of Solid and Liquid continuously, it is compared with belt filter press with plate and frame type filter-press, it is little to have floor space, the capital construction cost is low, treating capacity is big, and good separating effect need not wash by water in the work, can realize cleaning processing, and advantage such as easy to operate.Horizontal screw centrifuge all comprises case, bearing block, differential mechanism, rotary drum, screw feeder, feed pipe, screw feeder is made up of main shaft and spiral push-pads, it is the high accuracy shaft like parts that all fine and its outer round surface of static and dynamic equilibrium is provided with flight, end at main shaft offers the axis hole of being convenient to the feed pipe feeding, the outer round surface of helical pitches such as spiral push-pads ground distribution main shaft, the decanting zone is to wait cylindrical, the tapered distribution of dry section, in the decanting zone, main shaft is provided with discharging opening, high order end in the decanting zone is provided with the liquid phase outlet, extreme end at dry section is provided with the solid phase outlet, main shaft is fixed on the frame by two bearing blocks, rotary drum is tubbiness, be rotatably supported on the screw feeder, differential mechanism drives screw feeder and rotary drum, feed pipe is sleeved on the feed end of screw feeder, in the course of the work, feed pipe is fixed on the frame, main shaft is with respect to the feed pipe high speed rotating, owing to constantly be pressed into solidliquid mixture to be separated in the feed pipe, along with solidliquid mixture constantly is pressed into, the pressure of solidliquid mixture improves constantly between rotary drum and the screw feeder, solidliquid mixture constantly is penetrated between feed pipe and the main shaft inwall, solid particle in the solidliquid mixture carries out the brute force friction to feed pipe, not that the damage feed pipe is exactly the wear spindle endoporus, influence the normal service life of centrifuge, this is the existing ubiquitous technical barrier of horizontal screw centrifuge.
The utility model content
In order to overcome existing horizontal screw centrifuge above shortcomings, eliminate the obstruction between feed pipe and the main shaft endoporus, reduce wear, goal of the invention of the present utility model is to provide a kind of anti-block device for horizontal centrifugal machine feeding tube.
The technical scheme that the utility model is taked is:
Described anti-block device for horizontal centrifugal machine feeding tube, comprise feed pipe, main shaft and frame, feed end at main shaft offers the axis hole of being convenient to install feed pipe, feed pipe is fixed on the frame, feed pipe is installed in by anti-blocking cover in the endoporus of main shaft feed end, and the endoporus of described anti-blocking cover is a left handed threaded hole.
Further, described anti-blocking cover is made up of left end cap, threaded sleeve, loudspeaker cover, and the loudspeaker cover is fixed on the right-hand member of threaded sleeve, and left end cap is fixed on the left end of threaded sleeve, is provided with bearing and sealing ring between left end cap and the feed pipe.
Further, the endoporus of described threaded sleeve is left-handed trapezoidal thread or left-handed rectangular thread, and its helical pitch is 4～8 millimeters.
Because feed pipe is fixed on the frame, feed pipe is installed in the main shaft endoporus by anti-blocking cover, in the course of the work, the meeting of the solidliquid mixture in the feed cavity constantly is penetrated between feed pipe and the anti-blocking cover, the anti-blocking cover that endoporus is provided with left hand thread rotates at a high speed with main shaft, the solidliquid mixture that constantly will be penetrated between feed pipe and the anti-blocking cover is pushed feed cavity to, can prevent effectively that solidliquid mixture from entering between anti-blocking cover and the feed pipe, solid particle has been eliminated the stifled phenomenon of card between feed pipe and the main shaft to the friction of feed pipe in the minimizing solidliquid mixture.Use checking through reality, the charging of this device is smooth and easy, does not have the stifled phenomenon of card, and feed pipe is not easy to wear.
