Description

Technical Field

[0001] The utility model belongs to the technical field of transportation packaging bags, and particularly relates to a high-temperature resistant and moisture-proof railway car transportation bag. Background Art

[0002] When transporting powdery or granular materials by railway, railway car transportation bags are needed. In order to prevent material leakage, avoid material moisture, and improve the wear resistance of the bag body, a double-layer bag body is usually adopted, with a PE film as the inner layer and a PP cloth as the outer layer. An inlet pipe is connected to the bag body. In order to ensure the smooth discharge of the gas in the bag during the feeding process, in the prior art, several inlet pipes are usually directly used as exhaust pipes. Since the inlet pipe is a cylindrical pipe without shielding, the material is very easy to leak from the inlet pipe used as the exhaust pipe during the feeding process, increasing the material loss. In addition, since the inlet pipe is a double-layer structure, during the feeding process, once the inner layer and the outer layer of the inlet pipe are separated, the material is very easy to be discharged into the gap between the inner layer and the outer layer of the bag body, causing a large amount of waste of the material, and seriously affecting the feeding speed and the service life of the transportation bag. Summary of the Invention

[0003] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a high-temperature resistant and moisture-proof railway car transportation bag, which can avoid material leakage during the feeding process, improve the feeding speed, and extend the service life of the transportation bag.

[0004] The technical solution adopted by the utility model to solve its technical problems is: a high-temperature resistant and moisture-proof railway car transportation bag, including a bag body connected with an inlet pipe, both the bag body and the inlet pipe are composed of an inner layer and an outer layer, the inner layer is a PE film layer, and the outer layer is a PP cloth layer. The characteristics are that: an exhaust pipe is also connected to the bag body, and a filter screen is arranged in the exhaust pipe; the length of the inner layer of the inlet pipe is greater than the length of the outer layer of the inlet pipe, and the end of the inner layer of the inlet pipe is turned outwards to form a folded section, and the folded section is connected to the outer wall of the outer layer of the inlet pipe.

[0005] Further, the top of the folded section overlaps with the top of the outer layer of the inlet pipe.

[0006] Further, the folded section is fixedly stitched to the outer layer of the inlet pipe.

[0007] Further, the filter screen is a PP cloth with mesh holes.

[0008] Further, the filter screen is fixedly stitched to the top end of the exhaust pipe.

[0009] Further, the inlet pipe and the exhaust pipe are arranged at the top of the bag body along the length direction of the bag body, and the inlet pipe and the exhaust pipe are arranged at intervals.

[0010] Further, pipe mouth binding straps are fixedly connected to the outer walls of the inlet pipe and the exhaust pipe.

[0011] Further, the outer layer of the bag body includes a cylindrical side wall. A top wall is connected to the top opening of the cylindrical side wall by a sewing thread, and a bottom wall is connected to the bottom opening by a sewing thread. The cylindrical side wall has a flange extending beyond the sewing thread, and multiple suspension straps are sewn on the flange.

[0012] Further, the multiple suspension straps are evenly distributed along the flange.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. Since an exhaust pipe is also connected to the bag body and a filter screen is provided in the exhaust pipe, the filter screen can effectively block material leakage while ensuring the exhaust effect, thereby ensuring the feeding effect. Since the folded section formed by turning the outer end of the inner layer of the feeding pipe outward is connected to the outer wall of the outer layer of the feeding pipe, the inner layer and the outer layer of the feeding pipe cannot be separated from each other, thereby ensuring the stability of the feeding pipe during the feeding process, preventing materials from being wrongly discharged between the inner layer and the outer layer of the bag body, thus improving the feeding speed and extending the service life of the transport bag.

[0015] 2. Since the top of the folded section of the inner layer of the feeding pipe overlaps with the top of the outer layer of the feeding pipe, the feeding port of the feeding pipe is a three-layer structure, greatly improving the strength of the feeding port, preventing damage to the feeding port and material leakage, and improving the feeding reliability.

[0016] 3. Since the folded section is fixedly sewn to the outer layer of the feeding pipe, the inner layer and the outer layer of the feeding pipe are firmly fixedly connected together, and the processing is convenient and the strength is reliable.

[0017] 4. Since the filter screen is a PP cloth with mesh holes, it is simple to manufacture, low in cost, and more convenient for production and use.

[0018] 5. Since the filter screen is fixedly sewn to the top end of the exhaust pipe, it not only ensures the stable connection between the filter screen and the exhaust pipe, but also facilitates the cleaning of the filter screen, preventing the mesh holes from being blocked and affecting the exhaust effect.

[0019] 6. Since the feeding pipe and the exhaust pipe are arranged at intervals, the air squeezed by the materials inside the bag body during the feeding process can be discharged from the exhaust pipe in a timely and uniform manner, thereby ensuring the feeding speed.

[0020] 7. Since the pipe orifice binding straps are fixedly connected to the outer walls of the feeding pipe and the exhaust pipe, the feeding pipe and the exhaust pipe can be tied and closed after feeding, preventing material leakage during transportation.

[0021] 8. Since the cylindrical side wall of the outer layer of the bag has a flange that extends beyond the suture line and the sling is sewn on the flange, compared with the prior art where the connecting band is sewn on the outer wall of the bag and the sling is sewn on the connecting band, the flange and the cylindrical side wall in the present utility model are integral, thus greatly improving the connection strength between the sling and the outer side of the bag, avoiding damage to the bag due to excessive pulling force during transportation, and ensuring the transportation safety of the material.

[0022] 9. Since multiple slings are evenly distributed along the flange, the pulling force of the slings on the flange is more uniform, avoiding damage to the bag caused by local stress and extending the service life of the bag.

[0023] 10. The present utility model effectively solves the problem of material leakage of using the feed pipe as the exhaust pipe by connecting an exhaust pipe to the bag and setting a filter net on the inner wall of the exhaust pipe; turning the outer end of the inner layer of the feed pipe outward and fixing it to the outer layer of the feed pipe, ensuring that the material can only flow into the inner cavity of the bag along the inner wall of the inner layer of the feed pipe, further solving the problem of material leakage, and is worthy of popularization and use in the industry.

[0028] When the present utility model is in a working state, the end close to the ground is defined as the bottom end or the lower end, and correspondingly, the other end far from the ground is defined as the top end or the upper end.

[0029] The following further describes the present utility model in combination with the embodiments of the drawings:

[0030] As Figure 1As shown, the utility model provides a high temperature resistant and moisture proof train skin transport bag, a feeding pipe 2 is connected to the bag body 1, the bag body 1 and the feeding pipe 2 are both composed of an inner layer and an outer layer, the inner layer is a high temperature resistant and moisture proof PE film layer, and the outer layer is a high strength and wear resistant PP cloth layer. The bag body 1 is also connected to the exhaust pipe 3, and a filter screen 4 is connected to the inner wall of the exhaust pipe 3. The filter screen 4 is a PP cloth with meshes, and the filter screen 4 is sewn and fixed to the top of the exhaust pipe 3. Of course, the filter screen 4 can also be connected to other positions inside the exhaust pipe 3, but it is easier to clean when sewn to the top of the exhaust pipe 3. In order to improve the feeding efficiency, the feeding pipe 2 and the exhaust pipe 3 are arranged at the top of the bag body 1 along the length direction of the bag body 1, and the feeding pipe 2 and the exhaust pipe 3 are arranged at intervals.

[0031] like Figure 2 As shown, the length of the inner layer of the feed pipe 2 is greater than the length of the outer layer of the feed pipe 2, and the end of the inner layer of the feed pipe 2 is folded outward to form a folded section 20, and the folded section 20 is fixedly connected to the outer wall of the outer layer of the feed pipe 2 through a suture line, and the end of the folded section 20 has a flash that exceeds the suture line. In order to improve the strength of the feed port, the top of the folded section 20 overlaps with the top of the outer layer of the feed pipe 2, so that the feed port has a three-layer structure. Similarly, in order to improve the stability of the exhaust pipe 3, the exhaust pipe 3 is also composed of an inner layer of a PE film and an outer layer of a PP cloth. The exhaust pipe 3 is set to the same folding structure as the feed pipe 2, which will not be repeated here. The outer walls of the feed pipe 2 and the exhaust pipe 3 are fixedly connected with a pipe mouth tie 7. After the feeding is completed, the feed pipe 2 and the exhaust pipe 3 are respectively tied and closed by the pipe mouth tie 7, which can prevent material leakage during transportation.

[0032] The outer layer of the bag body 1 includes a cylindrical side wall 10, the top opening of the cylindrical side wall 10 is connected to the top wall by a suture line, and the bottom opening is connected to the bottom wall by a suture line. The cylindrical side wall 10 has a flash 5 beyond the suture line, and a plurality of slings 6 are sutured on the flash 5, and the plurality of slings 6 are evenly distributed along the flash 5. During the material transportation process, the slings 6 evenly pull the flash 5 extending from the cylindrical side wall 10, effectively preventing the outer layer of the bag body 1 from being torn, thereby extending the service life of the transport bag and ensuring the transportation safety of the materials.

[0033] Specific implementation of the utility model:

[0034] In use, first fully open the bag body 1 and set it on the inside of the railway wagon, arrange the bag body 1 to match the internal space of the railway wagon, and fix the sling 7 on the corresponding hanging ring of the railway wagon. Connect the feed pipe 2 to the discharge pipe of the discharging device and start feeding. Since the folded section of the inner layer 21 of the feed pipe is connected to the outer wall of the outer layer 22 of the feed pipe, the material can only flow downward along the inner wall of the inner layer 21 of the feed pipe into the cavity of the bag body 1. During the feeding process, the air in the inner cavity of the bag body 1 is discharged through the exhaust pipe 3. Since a filter screen 4 is provided in the exhaust pipe 3, the filter screen 4 can not only meet the exhaust requirement but also effectively prevent the material in the bag body 1 from leaking through the exhaust pipe 3. After the feeding is completed, use the pipe mouth binding band 7 to tie and close the feed pipe 2 and the exhaust pipe 3 respectively to prevent material leakage during transportation.

Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes.
