Abstract

A common rotary vane wheel feeder has the worst problem that vanes are abraded too fast, and generally, machine halt maintenance, vane overlaying, machining and the like are needed after a machine runs for a few months. A carbon black rotary vane wheel adjustable vane feeder is composed of a shell, an end cover, an vane wheel frame, adjustable vanes, an vane wheel shaft, studs, plug screws, a transmission device, an end cover adjusting pad and the like. The vane wheel frame is a framework for the vanes to be mounted and is a winding reel shaped like a barrel, and baffles are arranged at the two ends of the vane wheel frame. A plurality of lift-and-right through vane grooves distributed radiately are formed in the vane wheel frame, the adjustable vanes are mounted in the vane grooves, and the vane grooves and the adjustable vanes are connected and adjusted through two studs. Two plug screw holes are formed in the shell, and directly face the two studs on the adjustable vanes. The radial positions of the vanes can be adjusted by putting a socket head wrench from the plug screw holes to rotate the studs. A few times of vane adjustment and maintenance need to be carried out in one or two years, the trouble of equipment demounting, overlaying, machining and the like every time is avoided, maintenance fees can be lowered, and maintenance time can be saved.

Description

Carbon black rotary blade adjustable vane loader

Technical field

The present invention relates to a kind of carbon black production equipment, especially rotary blade loader.

Background technology

Known carbon black rotary blade loader is by housing, with the impeller of several stationary blades, end cap, bearing arrangement, shaft sealer, the compositions such as transmission device; Principle of work is: transmission device impeller is rotated in cylindrical shell, and the carbon black powder falling into from top hopper fills in interlobate space, with blade rotary, falls into below feeding equipment; During loader work, can be by upper, below air pressure cuts off, and plays the effect of lock gas.The greatest problem of rotary blade loader is that the blade wear of impeller is too fast, and blade severe wear had both affected feed efficiency, affected again air locking energy; The rotary blade loader that carbon black industry is used, generally turning round 2～3 months will shutdown maintenance, whole loader need to be removed, again impeller is removed, on blade radial top, carry out weld deposit repairing, then Vehicle Processing again, then install the running of resuming production; Each maintenance is pretty troublesome very expensive very time-consuming.

Summary of the invention

In order to improve the too fast problem of rotary blade loader blade wear, the invention provides the adjustable rotary blade loader of a kind of blade radial; When blade tip may wear to a certain degree, can implement radiai adjustment to blade, make up in time wearing and tearing vacancy, and reach the object that detaching equipment just can not keep in repair.

The technical solution adopted for the present invention to solve the technical problems is: carbon black rotary blade adjustable vane loader is by housing, end cap, impeller frame, adjustable vane, paddle shaft, bearing arrangement, axle end sealing device, thru-bolt, plug screw, driving device, the compositions such as end cap adjusting pad, is characterized in that: impeller frame is the impeller framework that adjustable vane is installed, and there is the spool of baffle plate at shape approximation thick cyclinder two ends; On impeller frame, there are several radial distribution, axially penetrating, go deep into the blade groove in cylindrical wall, plate shaped adjustable vane can be radially movable in blade groove; In the aspect of adjustable vane Ban center, there are two upper and lower penetrating threaded holes; Also there are two radially screws baseplane at the blade groove of impeller frame; The in-built adjustable vane of each blade groove on impeller frame, by two thru-bolts the two connection with adjustable vane is regulated.Its feature also has: on the bus on the horizontal section on the face of cylinder of cylindrical shell, have two spiro pluging holes, when adjustable vane is still in level attitude, these two spiro pluging holes face two thru-bolts installing on adjustable vane, in housing outside, from spiro pluging hole, inwardly put in inner-hexagon spanner and rotate thru-bolt, can regulate adjustable vane radial position.

The invention has the beneficial effects as follows, can be set as 1～2 year the service life of the adjustable vane of loader; When blade tip may wear to a certain degree, as long as the short period shuts down, unload two plug screws on lower house, just energy adjusting vane; In one to two year, only carry out simple blade adjustments and safeguard, remove each detaching equipment from, the complicated maintenance such as built-up welding processing, also can reduce service expenditure, saves maintenance time.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, the present invention is further described.

1. housings in figure, 2. end cap, 3. impeller frame, 4. adjustable vane, 5. paddle shaft, 6. bearing arrangement, 7. axle end sealing device, 8. thru-bolt, 9. plug screw, 10. driving device, 11. end cap adjusting pads.

The specific embodiment

Fig. 3, in Fig. 4, housing (1), end cap (2), impeller frame (3), adjustable vane (4), paddle shaft (5), bearing arrangement (6), setting-up procedure and the constructional feature of thru-bolt (8) and end cap adjusting pad (11) are: first paddle shaft is installed on impeller frame, thru-bolt is put in adjustable vane, then adjustable vane is installed on impeller frame, rotate thru-bolt, the other end of thru-bolt is twisted into the connection that completes adjustable vane and impeller frame in the bolt hole of impeller frame; Then four combinations that connected are above put in housing, refilled two ends end cap, bearing arrangement etc.; Last hand turning, regulates each adjustable vane; Make they and body clearance minimum, but rotate and not till larger resistance with hand; By end cap adjusting pad (11), to regulate the gap of two end cap and impeller frame more afterwards.

In Fig. 4, two head threads of thru-bolt (8), one, an impeller frame adjustable vane even even, two can be an anti-positive screw thread; Also can be the screw thread of same rotation direction, but same rotation direction screw thread must be that pitch is unequal.

Fig. 3, in Fig. 5, the lateral length of adjustable vane (4), should slightly be shorter than the width of impeller frame, makes blade two ends not exceed impeller frame.

Fig. 2, in Fig. 7, while needing adjusting vane (4), blade will be aimed at the screw of plug screw (9); This needs impeller frame slow rotation so that visual inspection; The motor inverter that the adjusting of rotating speed is carried by equipment is controlled.
