Description

Technical Field

[0001] This utility model belongs to the field of powder conveying equipment, and in particular relates to a sealing joint for filling mobile powder tanks. Background Technology

[0002] A mobile powder tanker truck is a device used to transfer powder raw materials or finished powder products. During actual production, workers connect upstream equipment to the tanks on the mobile powder tanker truck using a flexible baghouse connector, allowing materials to be filled into the tanks.

[0003] However, the existing flexible connection method for cloth bags has problems with poor assembly convenience and inadequate sealing. Therefore, the assembly work between the cloth belt and the tank during filling consumes a lot of time, and after assembly, the powder material can easily escape along the splicing part, thus causing pollution to the surrounding environment. Utility Model Content

[0004] In view of this, the present invention aims to provide a sealing joint for filling mobile powder tanks to solve the above-mentioned technical problems.

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

[0006] A mobile powder tank filling sealing joint includes a joint body and an annular sealing airbag. The joint body has a clamping joint at its top and a support ring at its bottom, with the outer diameter of the support ring being larger than the outer diameter of the joint body. A blocking ring is also provided on the joint body, located between the clamping joint and the support ring, with the outer diameter of the blocking ring being larger than the outer diameter of the support ring. The annular sealing airbag is sleeved on the joint body, located between the support ring and the blocking ring, with the outer diameter of the annular sealing airbag being larger than the outer diameter of the support ring but smaller than the outer diameter of the blocking ring. An air inlet pipe is also provided on the annular sealing airbag, and a receiving hole for accommodating the air inlet pipe is provided on the blocking ring.

[0007] Furthermore, the mobile powder tank filling sealing joint also includes an adjustment component, which includes an adjustment ring and a lifting screw. The adjustment ring is movably sleeved on the joint body and is located between the annular sealing airbag and the support ring. A lifting screw hole is provided on the support ring, and the lifting screw is placed inside the lifting screw hole, with the top end of the lifting screw abutting against the bottom surface of the adjustment ring.

[0008] Furthermore, the adjustment assembly also includes a silicone protective pad located between the adjustment ring and the annular sealing airbag, and an embedding groove for accommodating the adjustment ring is provided on the bottom surface of the silicone protective pad.

[0009] Furthermore, there are two lifting screws, and the two lifting screws are arranged in a mirror image on both sides of the adjusting ring axis.

[0010] Furthermore, the bottom surface of the adjusting ring is provided with a positioning groove for accommodating the lifting screw.

[0011] Furthermore, the mobile powder tank filling sealing joint also includes a material blocking screen, which is detachably installed at the bottom end of the joint body.

[0012] Furthermore, the material-blocking screen is provided with a conical ridge with its tip pointing towards the top of the connector body, and the mesh aperture on the conical ridge is smaller than the mesh aperture in other areas of the material-blocking screen.

[0013] Compared with the prior art, the mobile powder tank filling sealing joint of this utility model has the following advantages:

[0014] (1) The mobile powder tank filling sealing joint of this utility model has an annular sealing airbag on the joint body. In use, the operator first connects the top of the joint body to the fabric belt of the upstream equipment using clamps, then inserts the bottom of the joint body into the feed hole of the mobile powder tank, and then inflates the annular sealing airbag. When the annular sealing airbag expands due to inflation, the gap between the feed hole and the joint body is sealed, thus facilitating a convenient and quick connection between the upstream equipment and the tank, and providing a good seal at the connection point, thereby improving work efficiency and preventing powder material leakage.

[0015] (2) The mobile powder tank filling and sealing joint of this utility model includes an adjustable adjusting ring as its adjusting component. Before use, the operator can drive the adjusting ring to move up and down according to the diameter of the feed hole on the mobile powder tank, thereby limiting the axial expansion space of the annular sealing airbag with the help of the adjusting ring and the blocking ring, so that the annular sealing airbag can obtain a radial expansion degree that matches the diameter of the feed hole after inflation, thus meeting different actual use requirements.

[0016] (3) The mobile powder tank filling sealing joint of this utility model has a material-blocking screen at the bottom of the joint body. By setting the material-blocking screen, lumpy powder materials can be intercepted, avoiding blockage of the feed hole of the mobile powder tank during filling. In addition, the device also has a conical ridge on the material-blocking screen, which can divert the material during the filling process and prevent the material from accumulating and blocking on the material-blocking screen.

[0029] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] A mobile powder tank filling sealing joint, the structure of which can be made of Figures 1-6 The following is an illustration. In this embodiment, the mobile powder tank filling sealing joint includes a joint body 1 and an annular sealing airbag 4. The joint body 1 is used to connect the mobile powder tank with the upstream equipment, and the annular sealing airbag 4 is used to seal the connection part to prevent the powder material from escaping during the filling process.

[0031] Specifically, the top of the connector body 1 is provided with a clamp connector 11, and the bottom of the connector body 1 is provided with a support ring 2 whose outer diameter is larger than that of the connector body 1. A blocking ring 3 with an outer diameter larger than that of the support ring 2 is also provided on the connector body 1. The blocking ring 3 is located between the clamp connector 11 and the support ring 2, and has a receiving hole 31. The outer diameter of the annular sealing airbag 4 is larger than that of the support ring 2 but smaller than that of the blocking ring 3, and the annular sealing airbag is also provided with an air inlet pipe 41. During assembly, the annular sealing airbag 4 is fitted onto the connector body 1 between the support ring 2 and the blocking ring 3, and the air inlet pipe 41 extends along the receiving hole 31 above the blocking ring 3.

[0032] During use, operators first connect the clamp connector 11 to the fabric belt of the upstream equipment using clamps. Then, the bottom end of the connector body 1 is inserted into the feed port of the mobile powder tank. Subsequently, air is injected into the annular sealing airbag 4 through the air inlet pipe 41, causing the annular sealing airbag 4 to expand. The inflation of the annular sealing airbag 4 seals the gap between the connector body 1 and the feed port, thus achieving a good sealing effect between the device and the mobile powder tank, preventing powder material from escaping during filling. Compared with existing fabric belt flexible connection methods, this device not only has a good sealing effect but also allows for quick assembly and disassembly through the inflation and deflation of the annular sealing airbag 4, thus offering excellent ease of use.

[0033] Because the feed hole diameters differ on mobile powder tanks of different specifications, in order to improve the adaptability of this device, the mobile powder tank filling sealing joint in this embodiment also includes an adjustment component. Specifically, the adjustment component may include an adjustment ring 5 and a lifting screw 6, wherein the adjustment ring 5 is movably sleeved on the joint body 1 between the annular sealing airbag 4 and the support ring 2, the support ring 2 is provided with a lifting screw hole 21, the lifting screw 6 is placed inside the lifting screw hole 21, and the top end of the lifting screw 6 abuts against the bottom surface of the adjustment ring 5.

[0034] Before use, operators can determine the required radial expansion degree of the annular sealing airbag 4 based on the diameter of the feed hole, and adjust the distance between the adjusting ring 5 and the blocking ring 3 by using the lifting screw 6, thereby limiting the axial expansion space of the annular sealing airbag 4. Since the radial expansion degree of the annular sealing airbag 4 will change after the axial expansion space is limited (when the same volume of gas is filled, the axial expansion space becomes smaller, and its radial expansion degree becomes larger, and vice versa), once the distance between the adjusting ring 5 and the blocking ring 3 is adjusted to a suitable level, inflating the annular sealing airbag 4 will match the actual radial expansion degree of the annular sealing airbag 4 with the diameter of the feed hole, thus achieving a good sealing effect.

[0035] Optionally, to improve the support stability of the adjusting ring 5 for the annular sealing airbag 4, two lifting screws 6 can be provided in the adjusting assembly, and the two lifting screws 6 should be arranged in a mirror image on both sides of the axis of the adjusting ring 5 to ensure that the adjusting ring 5 obtains a balanced lifting effect. Correspondingly, a positioning groove 51 for accommodating the lifting screws 6 can also be provided on the bottom surface of the adjusting ring 5, so as to prevent the end of the lifting screws 6 from slipping or shifting when lifting the adjusting ring 5.

[0036] In addition, to prevent the adjusting ring 5 from scratching the annular sealing airbag 4 during use, the adjusting assembly may also include a silicone protective pad 7. For example... Figure 5As shown, the silicone protective pad 7 is located between the adjusting ring 5 and the annular sealing airbag 4, and an embedding groove 71 for accommodating the adjusting ring 5 is provided on the bottom surface of the silicone protective pad 7. When the axial expansion space of the annular sealing airbag 4 is restricted by the adjusting component, the top and edge of the adjusting ring 5 will enter the embedding groove 71. At this time, the silicone protective pad 7 will wrap around the top and edge of the adjusting ring 5. After the annular sealing airbag 4 is inflated, the silicone protective pad 7 can prevent the adjusting ring 5 from directly contacting the annular sealing airbag 4, thereby protecting the annular sealing airbag 4.

[0037] In actual use, powder materials may clump together. To prevent clumps from clogging the feed hole of the mobile powder tank, the mobile powder tank filling sealing joint in this embodiment may also include a material blocking screen 8, and the material blocking screen 8 is detachably set at the bottom of the joint body 1.

[0038] During the filling of powder materials, the material first passes through the baffle screen 8 before entering the mobile powder tank. During this process, any lumps of material will be intercepted by the baffle screen 8. If the lumps are relatively loose, they will be broken up by impact upon contact with the baffle screen 8, thus smoothly entering the mobile powder tank. If the lumps are relatively compacted, they will be intercepted above the baffle screen 8 to prevent the lumps from clogging the feed port of the mobile powder tank.

[0039] Optionally, to prevent material from accumulating and clogging on the material-retaining screen 8, such as... Figure 6 As shown, the material-blocking screen 8 may be provided with a conical ridge 81 with its tip pointing towards the top of the connector body 1. When powder material comes into contact with the material-blocking screen 8, the conical ridge 81 can divert the material, preventing the powder material from accumulating above the material-blocking screen 8 due to excessive impact force. In addition, the mesh aperture on the conical ridge 81 should be smaller than the mesh aperture in other areas of the material-blocking screen 8, so as to facilitate the rapid passage of the diverted material through the material-blocking screen 8 and prevent the material from accumulating in the bottom area of ​​the conical ridge 81.

[0040] The effects of the above solution are explained below:

[0041] This embodiment provides a mobile powder tank filling and sealing joint, which enables rapid loading and unloading through the inflation and deflation of an annular sealing airbag, improving the convenience of joint assembly. Simultaneously, the inflation and expansion of the annular sealing airbag seals the connection points, resulting in a good sealing effect. Secondly, this device can drive the adjusting ring to rise and fall according to actual needs to adapt to feed holes of different diameters. Furthermore, this device can also block agglomerated materials through a material-blocking screen and divert materials through the conical ridges on the screen, thereby preventing material accumulation and blockage.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
