Abstract

The utility model relates to a centrifugal chlorine compressor which has few speed-changing components, stable operation, less noise and long life time. Both ends of a high-speed main shaft 6 are respectively provided with a blade wheel 1 and a nitrogen sealing device, the periphery of which is provided with a spiral case 8; a diffuser 11 is arranged in the front of the blade wheel 1; a skewed-tooth-shaped low-speed gear 4 which is connected with a low-speed shaft 9 which is connected with the motor is directly engaged with a skewed-tooth-shaped high-speed gear 5 which is connected with the high-speed main shaft; cross sections are both end parts of the high-speed main shaft 6 form triangles formed by that three outward convex arcs are mutually connected in a kissing mode to be enclosed; a shaft hole, of the blade wheel, which is matched with the high-speed main shaft 6 also forms a triangle formed by that the three outward convex arcs are mutually connected in the kissing mode to be enclosed. The compressor is suitable for the transportation of chlorine liquid or chlorine in middle and long distance.

Description

Chlorine centrifugal compressor

The utility model belongs to compressor, specifically is meant liquid chlorine or chlorine conveying compressor.

The chlorine of liquid chlorine or middle and long distance is carried in the big-and-middle-sized chemical industry for making chlorine and alkali factory production technology, all need use chlorine gas compressor.The running of its liquid chlorine pump of chlorine gas compressor in the prior art relies on a large amount of concentrated sulphuric scids and makes sealing compound and freezing mixture, and it expends height and befouling environment; The turbine chlorine gas compressor is also arranged, though more described liquid chlorine pump makes progress, but still there are many critical defects on its structure, comprise that 1. the Placement of quick runner is the periphery structural type, the dynamic balance that mechanical assemblies is adjusted before its assembling in operation process is vulnerable to destroy, high speed rotating centrifugal force can progressively increase, and easily produces the peril that impeller damages; 2. speed increaser is the two-stage speed change, and volume is big, and movement parts is many, and comprehensive running accuracy is low.

The purpose of this utility model is to provide a kind of sulfuric acid sealing that need not for overcoming above-mentioned defective, and running is steady, and the degree of balance is good, and noise is little, and movement parts is less, the chlorine centrifugal compressor that the life-span is long.

The technical solution of the utility model chlorine centrifugal compressor is that high-speed main spindle two ends on the speed increaser are separately installed with impeller and its periphery of nitrogen envelope device is provided with spiral case being installed on, impeller the place ahead is provided with Diffuser, the lower velocity shaft that connects with motor is installed on the speed increaser, its special way is to be provided with intermeshing low speed gear in the speed increaser and high gear is linked in lower velocity shaft and high-speed main spindle respectively, and high-speed main spindle two end part cross section is that the impeller axis hole that triangle cooperates with it is the triangle axis hole.

Described triangle can be this shape, it is the shape that its three limit surrounds for the evagination camber line, so when overcoming high-speed main spindle and impeller cylndrical surface drawback, can further increase the Percent of contact area between high-speed main spindle and impeller, improve smoothness of operation in conjunction with generation.

The utility model is the setting of employing single-stage speed change at lower velocity shaft with at a high speed, and the low speed gear that promptly connects lower velocity shaft directly meshes with the high gear that connects high speed shaft, and this low speed gear and high gear are preferably helical gear, stable drive like this, and noise is little.

The utility model since high-speed main spindle and impeller in conjunction with adopting triangle cylinder combination, commonly use defectives such as dynamic balancing destructible due to the combination of cylndrical surface, impeller be fragile so can overcome; Owing to be provided with intermeshing low speed gear and high gear is linked in lower velocity shaft and high-speed main spindle respectively in the utility model speed increaser, make to be the transition of single-stage speedup between lower velocity shaft and high-speed main spindle, thereby can reduce transmission part again, reduce volume, reduce noise.

Below in conjunction with description of drawings mode of execution of the present utility model.

Fig. 1 is the utility model chlorine centrifugal compressor structural representation;

Fig. 2 is an impeller axis hole schematic representation.

A kind of chlorine centrifugal compressor of the present utility model, speed increaser 10 tops are provided with high-speed main spindle 6 through bearing 3, high-speed main spindle 6 two ends are separately installed with impeller 1 and nitrogen envelope device 2 its peripheries are provided with spiral case 8, impeller 1 the place ahead is provided with Diffuser 11, speed increaser 10 bottoms are equipped with lower velocity shaft 9 and link through coupling 7 and motor output shaft, be associated with plagiodont low speed gear 4 respectively on lower velocity shaft and the high speed shaft and plagiodont high gear 5 is positioned at speed increaser 10, low speed gear 4 is meshing with each other with high gear 5 and constitutes turn up 22500～2500r/min that the single-stage speed increasing mechanism makes high-speed main spindle 6, high-speed main spindle 6 two end part cross sections are that three evagination camber lines are kissed mutually and connect surround triangular shaped, impeller 1 axis hole of Pei Heing also is that three evagination camber lines are kissed mutually and connect surround triangular shaped with it, as shown in Figure 2.
