Detailed Implementation

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.

[0025] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each drawing; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "a" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0026] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0028] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0030] As shown in Figures 1 to 3, a two-in-one transfer valve for transferring toxic powder is shown in one embodiment of the present invention. It includes a transfer valve body 1, a scraping component 2 fixed inside the transfer valve body 1, a connecting component 3 installed at both the upper and lower ends of the transfer valve body 1, and an operating handle 4 installed on the side of the transfer valve body 1.

[0031] The scraping assembly 2 includes a valve plate 21, with a rotating groove 22 inside the valve plate 21. A mounting block 23 is fixed in the rotating groove 22, and a motor 24 is fixed inside the mounting block 23. A rotating shaft 25 is fixed at the output end of the motor 24, and a scraper 26 is fixed on the outside of the rotating shaft 25. The scraper 26 is made of flexible silicone material, which allows it to scrape off highly viscous powder or brittle powder. There are two sets of valve plates 21, and scrapers 26 are installed on the outside of both sets of valve plates 21.

[0032] In some examples, a rotating rod 29 is fixed to the side of the valve plate 21. A wiring groove 210 is provided inside the rotating rod 29. A connecting wire 211 is installed in the wiring groove 210. The other end of the connecting wire 211 is electrically connected to a first conductive plate 212. The rotating rod 29 is fixed on the operating handle 4. When the operating handle 4 is rotated, the first conductive plate 212 on the rotating rod 29 rotates synchronously.

[0033] In some examples, the wiring slot 210 is connected to the rotating slot 22, and the end of the connecting wire 211 away from the first conductive piece 212 is fixed to the motor 24, so that the motor 24 can be rotated by operating the handle 4 to connect the first conductive piece 212 and the second conductive piece 213, thereby allowing power to be supplied to the motor 24 through the connecting wire 211, so that the motor 24 drives the scraper 26 to rotate.

[0034] In some examples, an extension ring 214 is fixed to the outside of the transfer valve body 1, and a second conductive sheet 213 is fixed to the inner wall of the extension ring 214. When the second conductive sheet 213 is connected to the first conductive sheet 212, current can be generated, and power can be supplied to the motor 24 through the connecting wire 211.

[0035] In some examples, four sets of scrapers 26 are provided, which are evenly distributed on the outside of the rotating shaft 25. A guide vane 27 is fixed between two sets of scrapers 26. The guide vane 27 is inclined. A sealing ring 28 is provided at the rotating connection between the rotating shaft 25 and the valve plate 21. The guide vane 27 can generate airflow during the rotation of the scraper 26, thereby cleaning the gap between the valve plate 21 and the transfer valve body 1 and the powder residue on the inner wall. At the same time, when the powder is conveyed in the transfer valve body 1, it can improve the airflow generated by the rotation of the guide vane 27, thereby improving the conveying efficiency of the powder in the transfer valve body 1.

[0036] For example, as shown in Figure 3, when the transfer valve body 1 is needed to transfer toxic powder, the transfer valve body 1 is first installed between the two sets of devices via the connecting assembly 3. Then, when the toxic powder enters the transfer valve body 1, the operating handle 4 is manually rotated, causing the operating handle 4 to drive the rotating rod 29 and the valve plate 21 to rotate, so that the valve plate 21 is in an upright state inside the transfer valve body 1. Then, the first conductive plate 212 on the rotating rod 29 rotates and comes into contact with the extension ring 214 in the second conductive plate 213 on the side of the transfer valve body 1, thereby generating power between the first conductive plate 212 and the extension ring 214, which is then transmitted to the motor 24 via the connecting wire 211, so that the motor 24 can drive the rotating shaft 25 to rotate, thereby causing the scraper 26 and guide vane 2 on the outside of the rotating shaft 25 to rotate. 7. When the scraper 26 rotates, it can clean the powder residue attached to the surface of the valve plate 21. Then, when the scraper 26 rotates, the guide vane 27 rotates to generate airflow, thereby cleaning the powder residue in the gap between the transfer valve body 1 and the valve plate 21. At the same time, when the guide vane 27 rotates, it can accelerate the transfer efficiency of toxic powder inside the transfer valve body 1, thereby improving the transmission of toxic powder. During the transmission process, the scraper 26 and the guide vane 27 clean the surface of the transfer valve body 1 and the valve plate 21, which can prevent powder residue from remaining inside the valve plate 21 and the transfer valve body 1, and can also avoid cross-contamination between different toxic powders. It also saves the need to disassemble the transfer valve body 1 and perform additional cleaning inside the transfer valve body 1.

[0037] As shown in Figures 4 and 5, a two-in-one transfer valve for transferring toxic powder is illustrated in another embodiment of this utility model. It includes a connecting assembly 3 comprising a connector 31. A slide rod 32 is slidably connected inside the connector 31. An outer connecting ring 33 is fixed to one end of the slide rod 32, and an inner connecting ring 34 is fixed to the other end. A threaded groove is formed on the outer side of the outer connecting ring 33, and an internal threaded groove is formed on the inner side of the inner connecting ring 34. When the outer connecting ring 33 is closed, the inner connecting ring 34 is in a separated state. Four sets of both the outer and inner connecting rings 33 and 34 are provided. The connection point between adjacent sets of outer and inner connecting rings 33 and 34 is an inclined surface to prevent jamming during movement.

[0038] In some examples, an elastic sealing block 38 is fixed between the outer connecting ring 33 and the connector 31. The elastic sealing block 38 is used to ensure that the outer connecting ring 33 and the pipeline are directly sealed when the transfer valve body 1 is connected to a larger-sized pipeline.

[0039] In some examples, the connector 31 has a groove 39 inside, and an adjusting plate 35 is slidably connected in the groove 39. The adjusting plate 35 is fixed to the top of the slide rod 32, and a limiting rod 36 is inserted in the adjusting plate 35. A limiting groove 37 is opened at the bottom of the groove 39. By adjusting the sliding adjustment of the adjusting plate 35, the outer connecting ring 33 and the inner connecting ring 34 can slide, thereby changing the size of the connection diameter. After adjustment, the limiting rod 36 can be inserted into the limiting groove 37 to prevent the slide rod 32 from shifting.

[0040] For example, as shown in Figure 5, when the transfer valve body 1 needs to connect to pipelines of different diameters, the sliding rod 32 can be slid in the connector 31 by manually pushing the adjusting plate 35, so that the outer connecting ring 33 and the inner connecting ring 34 move synchronously. When the outer connecting ring 33 moves outward, the elastic sealing block 38 expands outward. When the outer connecting ring 33 and the inner connecting ring 34 move to the appropriate position, the limiting rod 36 in the adjusting plate 35 is pressed down, so that the limiting rod 36 is locked in the limiting groove 37 at the bottom of the sliding groove 39 by the sliding rod 32, so that the diameter of the outer connecting ring 33 matches the pipeline connection. When the pipeline connection is small, the pipeline can be threaded into the inner connecting ring 34, which can improve the connection adaptability of the transfer valve body 1.

[0041] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
