Description

1296956 IX. INSTRUCTIONS OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION The present invention relates generally to apparatus for sandblasting systems, and more particularly to a device having a synchronized feeder and sandblasting generator. The present invention will be disclosed in conjunction with, but not limited to, a carbon dioxide blasting system having a squeegee that is synchronized to the feeder by a drive belt. [Prior Art] A sand blasting system has existed for several decades. Typically, sand (also known as blasting media) is fed by a feeder into a conveying stream and delivered as entrained grit to a sandblasting nozzle that is directed from the blasting nozzle to a workpiece or other aims. The grit may be stored in a funnel or produced by the grit blasting system and directed to the feeder for introduction into the transport gas. An apparatus for producing carbon dioxide grit is referred to as a squeegee (for example, disclosed in U.S. Patent No. 5,520,572, the disclosure of which is incorporated herein by reference) The tooth is moved over the carbon dioxide block. The sand (also known as the granule) is produced and fed to the inlet of the feed steal. This feeder is disclosed in the sandblasting system filed on April 17, 2002.

The teachings of the present invention can be used in a blasting apparatus in which sand fines I09482.doc 1296956 are produced and directed to a feeder. [Embodiment] In the following, the same reference characters in the several views represent the same or corresponding parts. Again, in the following description, it should be understood, such as before. The terms rear, inner and outer terms and similar terms are terms that are convenient to describe and should not be construed as limiting terms. The use of a device in the present invention is not intended to be limited to the scope of the device or parts thereof described herein, but rather to attach or utilize such devices or portions thereof. The invention will now be described in detail with reference to the drawings. Referring to Figure 1, a blasting system (indicated generally by 2) includes a frame 4 that provides a branch # and "attaches an external panel (not shown) to enclose most of the components. System 2 includes a sandblasting generator 6, feed The controller 8 and the control panel 1 are shown as a doctor blade that is configured to receive a commercially available standard size dry ice cube, for example, a 6" block. Figures 3 and 4 As seen therein, one end of the generator 6 includes a casing 12 in which grit or granules are formed and flowed by gravity to the inlet 14 of the feeder 8. In the case of a squeegee, the casing 12 contains a carryable one. Or a plurality of two or two rotatable loaders (four), the carrier is "reverse to the dry ice block (not shown and moved relative to the dry ice to scrape the particles from the block. The sand is from the mouth to the / The lower inflow into the inlet 14 and into the cavity, the cavity is also referred to as a cavity) is formed in the circumferential surface of the rotor 2G. As shown, the rotor 可由 can be driven directly by the motor 22 (e.g., by the legs 24) or can be indirectly driven by any suitable power transmission configuration. The grit is conveyed to a discharge port 26 of a feeder 8 of 109482.doc 296956, where the grit is introduced into the conveying gas stream, thereby self-hunting to directly or indirectly connect the delivery hose (not shown) to the outlet bee 2 $ Discharge to deliver it to the blast nozzle (not shown). The inlet 埠3 of the feeder 8 is connected to a delivery gas source (not shown) having suitable flow capacity and pressure (e.g., up to 12 5 p s i). The carrier 14 is supported and driven by a shaft 32 that is rotatably supported by the housing 12. The drive pulley 34 is fixed to the shaft 32 with the key 36 preventing rotation therebetween. The drive pulley 34 can be coupled to the shaft 32, such as a spline, in a non-condensing manner using any suitable configuration. The drive pulley 34 is coupled to the end 38 of the rotor 2 by a drive belt 40. The drive pulley 34 includes a plurality of teeth C that engage complementary shaped teeth formed on the inside of the drive belt 4〇. The end portion 38 also includes a plurality of complementary shaped teeth 44 that engage the inside of the drive belt 4 亦可. An idler pulley 46 can also be used. The rotor 20, which is driven by the motor 22, thus drives the carrier 14 and thus drives the working edge 16 at a fixed ratio. This causes the grit generation of the sandblasting generator 6 to be synchronized with the feeding rate of the feeder 8 . By synchronizing the rate at which the sand is produced; and the rate at which the granules are fed to and from the feeder, the blasting is then delivered to the carrier gas, thereby forming a preferred continuous movement, thereby avoiding being at rest and Avoid gathering blocks. In the embodiment shown by the present invention, the ratio is about 1〇:1, wherein the speed of the sand particles is about about 5% of the sand particles per minute to the point of view: the feed gas per minute. Different feed rates may be used depending on the desired feed rate. For example, it may be necessary to use any suitable drive mechanism, such as a chain and a sprocket, when using a higher flow rate nozzle. I09482.doc 1296956 provides a variable transmission that allows easy use of nozzles of different flow rates and delivery of airflow. The motor 22 can be interposed between the shaft 32 and the rotor 20 by a suitable drive mechanism between the shaft 32 and the motor 22 and between the rotor 2 and the motor 22. Any suitable rotary motion and power source can be used. For the purposes of illustration and description, a description of a preferred embodiment of the invention has been presented.
