Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of powder pipe joints, and in particular relates to a powder recovery pipe joint. Background Art
[0002] During the transfer of metal powder or the recovery of powder through a pipeline, when the metal powder recovery barrel is full, it needs to be replaced manually. However, during the replacement process, the residual powder in the pipeline will fall out of the pipe mouth due to the vibration of the replacement action, causing the powder to float. This not only causes the replacement personnel to inhale the powder and endanger their health, but also causes the powder to fall to the ground and become contaminated and cannot be recycled. Utility Model Content
[0003] In view of the above problems, the purpose of the utility model is to provide a powder recovery pipe joint which will not spill powder when the joint is replaced.
[0004] The utility model is realized by the following technical solutions:
[0005] A powder recovery pipe joint, comprising an upper joint, a lower joint, a sealing block and a push rod; the inner side of the bottom opening of the upper joint is a tapered opening, and is movably connected to the top of the lower joint; a hollow structure is arranged inside the lower joint; the push rod is placed on the hollow structure inside the lower joint; the sealing block is connected to the top of the push rod, and the sealing block is located inside the upper joint; the diameter of the sealing block is larger than the minimum inner diameter of the upper joint; after the upper joint is separated from the lower joint, the sealing block moves downward under the action of gravity and seals in the tapered opening at the bottom of the upper joint; after the upper joint and the lower joint are connected together, the top of the push rod can push the sealing block out of the tapered opening of the upper joint; a sealing gasket is arranged at the connection between the upper joint and the lower joint; the hollow structure inside the lower joint is cross-shaped; a sealing ring is installed on the sealing block; the push rod is T-shaped; the outer sides of the upper joint and the lower joint are connected by a clamp.
[0006] Beneficial effects of the utility model:
[0007] The utility model has a simple structure. The sealing block cooperates with the ejector rod so that when the upper joint is connected to the lower joint, powder can pass through normally. When the upper joint is separated, the sealing block blocks the upper joint interface so that the powder will not spill out. BRIEF DESCRIPTION OF THE DRAWINGS
[0008] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0013] The following is a description of the implementation of the present invention by means of specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.
[0014] It should be noted that the structures, proportions, sizes, etc. drawn in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the utility model, so they have no substantial technical significance. Any modification of the structure, change of the proportional relationship or adjustment of the size, without affecting the effects and purposes that can be achieved by the utility model, should still fall within the scope of the technical content disclosed by the utility model. At the same time, the terms such as "upper", "lower", "left", "right", "middle" and so on quoted in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the utility model. The change or adjustment of their relative relationship should also be regarded as the scope of the implementation of the utility model without substantial change of the technical content.
[0015] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. It should be noted that the terms "include", "comprise" or any other variants are intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also includes other elements that are not explicitly listed, or also includes elements inherent to such process, method, article or device.
[0016] like Figure 1-Figure 3 The powder recovery pipe joint shown comprises: an upper joint 1, a sealing ring 2, a sealing gasket 3, a lower joint 4, a sealing block 5, and a push rod 6.
[0017] The bottom of the upper joint 1 is conical and connected to the top of the lower joint 4. The outer sides of the upper joint 1 and the lower joint 4 are connected by a clamp.
[0018] A hollow cross-shaped structure is arranged inside the lower joint 4 .
[0019] The push rod 6 is placed on the cross-shaped structure inside the lower joint 4. In order to ensure the smooth flow of powder in the pipeline, the push rod 6 is T-shaped.
[0020] The sealing block 5 is connected to the top of the push rod 6, and the sealing block 5 is located inside the upper joint 1; the diameter of the sealing block 5 is larger than the minimum inner diameter of the upper joint 1, and is used for when the upper joint 1 and the lower joint 4 are separated, the sealing block 5 moves downward under the action of gravity and seals in the conical opening at the bottom of the upper joint 1 to prevent powder from spilling out.
[0021] After the upper joint 1 and the lower joint 4 are connected together, the top of the push rod 6 can push the sealing block 5 out of the conical opening of the upper joint 1, and the powder can pass normally.
[0022] A sealing gasket 3 is provided at the connection between the upper joint 1 and the lower joint 4 .
[0023] The sealing block 5 is provided with a sealing ring 2 .
[0024] Working principle:
[0025] When in use, the upper joint 1 and the lower joint 4 are connected, and the connection can be fixed by a clamp. At this time, the push rod 6 is located on the cross-shaped structure of the lower joint 4, and the sealing block 5 is pushed out of the cone mouth of the upper joint 1, so that the upper joint 1 and the lower joint 4 are in a connected state. When it needs to be taken out, the upper joint 1 and the lower joint 4 are separated. At this time, due to the influence of gravity, the sealing block 5 moves downward to block the cone mouth of the upper joint 1 to prevent residual powder in the pipeline from spilling out.
