Description

Technical Field

[0001] This utility model relates to the field of pipeline sealing technology, and in particular to a device for convenient sealing and conveying of powder materials. Background Technology

[0002] In powder conveying, auger conveyors are frequently used. Auger conveyors can transport powder from the discharge port of equipment A to the feed port of equipment B from bottom to top. They are widely used due to their simple structure and low cost.

[0003] In the process of implementing this solution, the inventors discovered the following problems in the prior art that have not been well resolved: after the auger's pipe is connected to the feed pipes of the two devices, a certain degree of vibration will be generated when the auger rod rotates. The vibration will be transmitted to the sealing gasket or sealant at the pipe connection. Over time, this will cause gaps to appear at the seal, resulting in insufficient sealing. Therefore, this application proposes a device for convenient sealing and conveying of powder. Utility Model Content

[0004] The main objective of this invention is to provide a device for convenient sealed conveying of powder materials, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A device for convenient sealed conveying of powder includes a auger tube. A feed pipe is provided at one bottom end of the auger tube, and a receiving pipe is provided below the feed pipe. Flange connecting plates are fixed to the outer walls of the feed pipe and the receiving pipe at their adjacent ends. A sealing assembly is provided between the feed pipe and the receiving pipe. The sealing assembly includes a flange rubber gasket. An inner wall rubber gasket is provided at both the top and bottom ends of the flange rubber gasket. An inner conical sealing rubber gasket is provided at the end of the inner wall rubber gasket away from the flange rubber gasket. An embedded rubber gasket is provided on the outer wall between the inner wall rubber gasket and the inner conical sealing rubber gasket. An annular embedded groove is carved into the inner wall of the feed pipe and the receiving pipe at their adjacent ends.

[0007] Preferably, the inner wall rubber gasket, the inner conical sealing rubber gasket, and the embedded rubber gasket at the top of the flange rubber gasket are all inserted into the inside of the feed pipe, and the inner wall rubber gasket, the inner conical sealing rubber gasket, and the embedded rubber gasket at the bottom of the flange rubber gasket are all inserted into the inside of the receiving pipe.

[0008] Preferably, the outer walls of the inner wall rubber pad and the inner conical sealing rubber pad are respectively bonded to the inner walls of the feed pipe and the receiving pipe.

[0009] Preferably, the embedded rubber pads are respectively embedded in the annular embedded grooves of the feed pipe and the receiving pipe, and the size of the embedded rubber pads matches the size of the annular embedded grooves.

[0010] Preferably, each of the flange connecting discs has an annular pressing edge at one end, which contacts the top and bottom of the flange rubber gasket, respectively.

[0011] Preferably, bolts are provided between the two flange connecting plates and the flange rubber gasket, and the flange connecting plates and the flange rubber gasket are detachably connected by bolts.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This application improves the feed pipe, receiving pipe, and sealing components, transforming them from a single-layer seal to a multi-layer seal. Even with long-term vibrations transmitted to the feed pipe, receiving pipe, and sealing components, the seals can maintain a good sealing effect and will not easily cause problems such as insufficient pipe sealing that affect the normal conveying of powder.

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] like Figure 1-4As shown, a device for convenient sealed conveying of powder includes a auger pipe 1. A feed pipe 2 is provided at one bottom end of the auger pipe 1, and a receiving pipe 3 is provided below the feed pipe 2. Flange connecting plates 5 are fixed to the outer walls of the feed pipe 2 and the receiving pipe 3 at their adjacent ends. A sealing assembly 4 is provided between the feed pipe 2 and the receiving pipe 3. The sealing assembly 4 includes a flange rubber gasket 41. An inner wall rubber gasket 42 is provided at both the top and bottom ends of the flange rubber gasket 41. An inner conical sealing rubber gasket 43 is provided at the end of the inner wall rubber gasket 42 away from the flange rubber gasket 41. An embedded rubber gasket 44 is provided on the outer wall between the inner wall rubber gasket 42 and the inner conical sealing rubber gasket 43. An annular embedded groove 6 is carved into the inner wall of the feed pipe 2 and the receiving pipe 3 at their adjacent ends.

[0021] Specifically, the inner wall rubber gasket 42, the inner conical sealing rubber gasket 43, and the embedded rubber gasket 44 at the top of the flange rubber gasket 41 are all inserted into the inside of the feed pipe 2. The inner wall rubber gasket 42, the inner conical sealing rubber gasket 43, and the embedded rubber gasket 44 at the bottom of the flange rubber gasket 41 are all inserted into the inside of the receiving pipe 3. The outer walls of the inner wall rubber gasket 42 and the inner conical sealing rubber gasket 43 are respectively bonded to the inner walls of the feed pipe 2 and the receiving pipe 3. The embedded rubber gasket 44 is respectively embedded in the annular embedded groove 6 of the feed pipe 2 and the receiving pipe 3, and the size of the embedded rubber gasket 44 matches the size of the annular embedded groove 6. The flange connecting plate 5 is provided with an annular pressing edge 7 at the end closest to each other. The annular pressing edge 7 contacts the top and bottom of the flange rubber gasket 41 respectively, forming multiple seals.

[0022] Specifically, bolts 8 are provided between the two flange connecting plates 5 and the flange rubber gasket 41, and the flange connecting plates 5 and the flange rubber gasket 41 are detachably connected by bolts 8.

[0023] Working principle: After passing through the auger pipe 1, feed pipe 2, and sealing component 4, the powder is discharged into the receiving pipe 3. The upper inner conical sealing rubber gasket 43, inner wall rubber gasket 42, and flange rubber gasket 41, together with the lower inner wall rubber gasket 42 and inner conical sealing rubber gasket 43, form a guiding effect, allowing the powder to stay away from the gap at the connection between the feed pipe 2 and the receiving pipe 3, increasing the sealing performance. The inner wall rubber gasket 42 and inner conical sealing rubber gasket 43 are respectively bonded to the inner walls of the feed pipe 2 and the receiving pipe 3, increasing the sealing performance. The embedded rubber gasket 44 is embedded in the annular embedded groove 6 of the feed pipe 2 and the receiving pipe 3, which further increases the sealing performance. The flange connecting discs 5 are compressed by the installation of bolts 8, which further increases the sealing effect. The annular pressing edge 7 set at the end face of the flange connecting discs 5 that compresses the flange rubber gasket 41 can form a barrier edge, which further increases the sealing effect. Overall, the transition of powder will not easily cause the sealing performance to be insufficient due to the long-term vibration of the auger.

[0024] This application describes one of the connection points. The other connection point can be implemented in the same way as the technical points of this application. The connection point of the auger conveyor is a disclosed and mature prior art, and will not be described in detail in this application.
