Abstract

A rotary wheel (10) for mechanical surface processing device has multiple scoops (13) mounted on at least one disc (11) for delivering the sand blasting cleaning materials. The scoops (13) are releasably mounted on the disc (11), and can be fitted on the disc (11) at a basic position and a position relative to the basic position rotating 180 degrees around its middle axes, thereby a rotary wheel (10) can be manufactured for right or left (12) handed operation by turning of the scoops (13).

Description

Runner

The present invention relates to a kind of runner that is used for the mechanical surface treatment device, it has a plurality of camber blades that are arranged at least one dish and is used for the abrasive jet cleaning material is sent away.

This runner has the blade that turns to recessed bending usually to runner, come clean surface especially in the spraying equipment on rolled products surface at centrifugal motion, prove very effective the uniformity of abrasive jet cleaning material and the property easy to wear aspect of runner by a kind of abrasive jet cleaning material of usually forming by metallic particles.In spraying equipment, it is the clockwise direction rotation that a this runner part must be turned right, and a part must the i.e. rotation counterclockwise of left-hand rotation.Therefore up to the present, to having the wheel of camber blades, the runner that manufacturer must provide simultaneously and turn right.And concerning the management with conversion unit different runner type or vane type must be provided.

Task of the present invention is to propose a kind of runner, and it can be converted to left-hand rotation from right-hand rotation fast simply.

This task is to solve by a kind of like this runner that is used for the mechanical surface treatment device, it has a plurality of camber blades that are arranged at least one dish and is used for the abrasive jet cleaning material is sent away, it is characterized in that according to the present invention, blade detachably is installed at least one dish, wherein can be installed on this dish the position of longitudinal axis Rotate 180 ° in the middle of it at relative this home position of a home position with one, thus the runner that can make a kind of runner that can be used for turning left or be used to turn right by the upset of blade.Therefore can repack a right wheel into a left wheel apace in runner of the present invention, vice versa, and needn't runner be removed from equipment for this reason.Two kinds of different runner types needn't be provided now.Blade structure becomes absolute symmetry, thereby produces identical jet performance when turning right with left-hand rotation.

Blade can be provided with projection on its long side surface, this projection can be inserted in the groove in the dish.Here, groove can narrow down gradually to the excircle direction of dish, connects thereby produce a kind of clamping between blade and dish when runner rotates.Drop for fear of blade, can make groove and projection have a kind of dovetail cross-sectional shape.In addition, bottom land can be arranged for example peg made of rubber of elastomeric material, with the projection that increases blade and the friction between the groove.Blade is not only reliably avoided axially dropping but also reliably avoiding radially dropping in the runner installation process thus.

In a kind of runner form of implementation commonly used, blade arrangement is between two dishes.Blade can be between driven master and the shrouding disc at two dishes in runner of the present invention, but wherein blade can be fixed on two dishes by the projection in the insertion groove.Shrouding disc has improved the stability of runner.But, runner also can be only with a dish.

Describe a preferred embodiment of runner of the present invention below in detail by accompanying drawing.

Be illustrated as:

The blade-carrying master plane of Fig. 1 runner of the present invention;

Fig. 2 is along the sectional view of the cutting line II-II of runner shown in Figure 1;

The stereogram of Fig. 3 runner shown in Figure 1.

Runner 10 shown in Figure 1 has a driven dish 11 and the direction of rotation 12 recessed crooked blades 13 to runner 10 that are installed on this dish.Here, blade 13 is installed on the dish 11 and on the shrouding disc 14 shown in Figure 2 replaceably.Blade has projection shown in Figure 2 15 on its long side surface for this reason, and this projection 15 can be inserted in the radial slot 16 (Fig. 1,3) of dish 11.Having only in

dish

11,14 the runner, projection 15 and groove 16 can have a kind of cross section of swallow-tail form, thereby make blade 13 axially dropping along wheel 10 from this groove more not after projection 15 is inserted in the groove 16.By coiling 12 rotation, blade 13 is outwards supported firmly, produces a kind of clamping action thus when groove 16 radially outward narrows down gradually between projection 15 and groove 16.In addition, arrange the braking member 17 that some are made by elastomeric material such as rubber in the bottom of groove 16, increasing the friction between projection 15 and the groove 16, thereby in runner 10 is installed to process on the equipment, avoided blade 13 from groove 16, to skid off.

Convert right wheel if will take turns 10 to from illustrated left wheel, then can simply blade 13 be released from groove 16, longitudinal axis 19 Rotate 180s ° in the middle of it are inserted in the groove 16 with the projection 15 of its another long side surface.

As shown in Figure 2, blade 13 is arranged between master 11 and the shrouding disc 14, wherein fixing can the realization by projection 15 and corresponding groove 16 on two dishes 11,14.Two

dishes

11 and 14 interconnect by the dividing bush between the blade 13 18.

The clear outward appearance of projection 15 on blade 13 that shown of the stereogram of the runner 10 shown in Fig. 3.They become T shape, and wherein T shape bridge 15.1 is as the backstop of the outer boundary 16.1 of groove 16.On other three sides, projection 15 is surrounded by a lid 20, and described lid avoids material granule to invade in the groove 16.

Claims

1. runner that is used for the mechanical surface treatment device, it has a plurality of camber blades (13) that are arranged at least one dish (11) and is used for the abrasive jet cleaning material is sent away, it is characterized in that, blade (13) detachably is installed on the dish (11), wherein can be installed on this dish (11) position of longitudinal axis (19) Rotate 180 ° in the middle of it, thereby can make a kind of runner (10) of left-hand rotation (12) or runner (10) that is used to turn right of can be used for by the upset of blade (13) at relative this home position of a home position with one.
