Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures associated with the present invention are shown in the drawings, not all of them.

In the description of the present invention, unless otherwise explicitly specified or limited, the terms "connected", "connected" and "fixed" are to be construed broadly, e.g., as being fixedly connected, detachably connected, or integrated; can be mechanically or electrically connected; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meaning of the above terms in the present invention can be understood as a specific case by those skilled in the art.

In the present disclosure, unless expressly stated or limited otherwise, the first feature "on" or "under" the second feature may comprise direct contact between the first and second features, or may comprise contact between the first and second features not directly. Also, the first feature "on," "above" and "over" the second feature may include the first feature being directly above and obliquely above the second feature, or simply indicating that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature includes the first feature being directly under and obliquely below the second feature, or simply meaning that the first feature is at a lesser elevation than the second feature.

In the description of the present embodiment, the terms "upper", "lower", "left", "right", and the like are used in the orientation or positional relationship shown in the drawings only for convenience of description and simplicity of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention. Furthermore, the terms "first" and "second" are used only for descriptive purposes and are not intended to have a special meaning.

Three-product sorting requires separating the material into three products. The product 1 is not blown and enters a chute of the product 1 along the original track, and the chute of the product 1 is close to the position of the nozzle; the product 2 is blown by medium blowing force, the material enters a chute of the product 2, and the chute of the product 2 is positioned in the middle; the product 3 is injected by large injection force, the material enters the product 3 chute, and the product 3 chute is farthest away from the nozzle. The blowing into the product 3 chute is easy to realize, and only the maximum force is needed for blowing. The injection is difficult to enter the chute of the product 2, and the injection force is difficult to control and is difficult to completely match the size of the object block. Too large blowing force can cause the product 2 to enter the chute for the product 3, and too small blowing force can cause the product 2 to enter the chute for the product 1, so that the sorting precision is not high.

The existing three-product dry separator adopts two rows of nozzles to spray, and three spraying force adjustments of large nozzle and small nozzle spraying, large nozzle spraying and small nozzle spraying can be realized through combination. However, in actual separation, the shapes of the blocks are different, the sizes of the blocks are different, and the adjusting range of the three-stage blowing force adjustment is too small, so that the requirements of various blocks cannot be met.

Therefore, the utility model provides a nozzle can realize the multistage adjustable of jetting dynamics, has solved the unmatched problem of jetting dynamics and thing piece shape, and then has improved the sorting precision.

Specifically, as shown in fig. 1 and 2, the nozzle includes a main valve body 100 and a nozzle unit 200. The main valve body 100 includes a main air inlet 110, a main air outlet 120, a plurality of air flow channels 130 and a control valve, each air flow channel 130 is communicated with the main air inlet 110 and the main air outlet 120, and air for blowing the object blocks enters the main valve body 100 from the main air inlet 110, and is exhausted from the main air outlet 120 after flowing through the opened air flow channels 130. Control valves (not shown) are disposed in the gas flow channels 130, and each control valve can control the opening and closing of one gas flow channel 130, so that the control of the gas output of the total gas outlet 120 can be realized by controlling the number of the control valves. The nozzle unit 200 is communicated with the main gas outlet 120, specifically, the nozzle unit 200 is communicated with the main gas outlet 120 through the gas pipeline 140, and the gas sprayed from the main gas outlet 120 is sprayed to the object blocks through the nozzle unit 200, so that the object blocks are sorted. Therefore, the blowing force of the nozzle unit 200 can be controlled by controlling the air output of the main air outlet 120, and then the blowing force can be adjusted according to the size of the object, so that the sorting precision of the product is improved.

Furthermore, all the control valves are independent of each other, and each control valve can be independently opened and closed, so that the multistage adjustment of the blowing force is realized. Optionally, at least four gas flow channels 130 are provided, and the at least four gas flow channels 130 can realize adjustment of four blowing strengths, compared with the prior art that only three-stage blowing strength adjustment can be realized, on one hand, the adjustment direction of the blowing strength is larger, the matching degree of the blowing strength and the size of the object block is improved, and further, the sorting precision of the product is improved; on the other hand, only need a nozzle can realize the regulation of jetting dynamics, compare with the combination formula nozzle that adopts big nozzle + little nozzle among the prior art, reduced the quantity of spare part, be convenient for install. In this embodiment, be equipped with nine gas flow channels 130, set up nine control valves correspondingly, can realize nine grades of regulations of jetting dynamics at least, improved the matching degree between jetting dynamics and the thing piece greatly, and then improved the sorting precision of product. Of course, in other embodiments, the number of the gas channels 130 may be other, such as six, seven, or eight, and the like, and the arrangement is determined according to actual needs.

Alternatively, in one embodiment, the flow areas of the gas channels 130 are the same, and the nozzle force of the nozzle is adjusted only according to the opening number of the control valves, i.e. the number of adjustment steps of the nozzle force is equal to the number of the control valves. In another embodiment, one portion of the plurality of gas channels 130 is a large diameter channel and another portion is a small diameter channel. The nozzle with the structure has the advantages that the adjusting stages of the blowing force are not only related to the number of the control valves, but also related to the number of the opened large-caliber flow channels and small-caliber flow channels, and the adjusting stages of the blowing force are more. Preferably, the large-caliber flow channel and the small-caliber flow channel can be alternately arranged, so that the structural compactness is favorably improved. In other embodiments, the flow areas of the gas channels 130 may be different, some the same, or some different according to actual needs.

Preferably, with continued reference to fig. 2, a plurality of gas flow passages 130 may be spaced along the circumference of main valve body 100, which may improve the compactness of main valve body 100 and further reduce the size of main valve body 100, as compared to being lined up in the same direction.

Further, the control valve may be a manual valve or a solenoid valve. When the control valve is the solenoid valve, can open quantity and control through controller control solenoid valve and open which solenoid valve, intelligent degree is higher, is convenient for realize the quick sorting of product.

The utility model also provides a sorting machine, including foretell nozzle, the product sorting precision of this sorting machine is higher.
