[0001] The utility model relates to the technical field of adhesive powder transportation, in particular to a leakage-proof device for adhesive powder production and transportation. Background Art
[0002] Cement powder is a new type of gel material used to fill underground or mines. It uses tailings as aggregate and cement as binder. It has the advantages of low water content, strong natural water reducing ability, high density, fast water infiltration rate, good viscosity and strong water resistance. It is widely used in mine filling, underground grouting, road construction and other fields. After production, cement powder needs to be transported.
[0003] When transporting adhesive powder, a common transportation method is to pack the adhesive powder into packaging bags made of sealing materials, and then stack the sealed packaging bags on a transport vehicle for transportation. However, there are still some shortcomings in actual use. For example, when the packaging bags are sealed, due to the presence of air inside the packaging bags, the packaging bags stacked on the lower layer will be squeezed by the weight of other packaging bags during the palletizing operation, causing explosion. Therefore, the air inside the packaging bags must be squeezed out from the feed port before sealing. When the air inside the packaging bags is squeezed out manually, the adhesive powder inside the packaging bags is easily lifted up, causing the air to carry the adhesive powder to escape to the outside, thereby causing waste of adhesive powder.
[0004] Therefore, there is a particular need for a leak-proof device for producing and transporting glue-solid powder to solve the problems existing in the prior art. Utility Model Content

[0021] The above scheme is further described below in conjunction with specific examples. It should be understood that these examples are used to illustrate the present application and are not limited to the scope of the present application. The implementation conditions adopted in the examples can be further adjusted according to the conditions of the specific manufacturer, and the implementation conditions not specified are usually the conditions in conventional experiments.
[0022] Embodiment: A leak-proof device for production and transportation of glue-solid powder, see Figure 1-Figure 5 As shown, it includes a charging bag 1 and a foam sleeve 2. The charging bag 1 is made of waterproof material. The charging bag 1 is internally connected with a foam sleeve 2 for buffering. It also includes an air outlet pipe 6, a filter screen 7, a one-way valve 8, a connecting pipe 9, an air bag 10, and a screw cap 11. The front left side of the foam sleeve 2 is connected with an air outlet pipe 6. The air outlet pipe 6 passes through the outside of the charging bag 1. The air outlet pipe 6 is internally connected with a filter screen 7 for filtering air, and the air outlet pipe 6 is internally connected with a one-way valve 8 for one-way exhaust. The one-way valve 8 is located in front of the filter screen 7, so that the air filtered by the filter screen 7 is discharged from the one-way valve 8. The upper part of the air outlet pipe 6 is connected with a connecting pipe 9, and the upper end of the connecting pipe 9 is connected with an air bag 10. The front end of the air outlet pipe 6 is threadedly connected with a screw cap 11 for sealing. The air inside the foam sleeve 2 is squeezed into the air outlet pipe 6 by folding the feed port of the charging bag 1.
[0023] See also Figure 1-Figure 2 As shown, it also includes a sealed bag opening 3, a first Velcro 4, a second Velcro 5 and a drawstring 12. The left part of the loading bag 1 is connected to the sealed bag opening 3, the outside of the sealed bag opening 3 is connected to the first Velcro 4 distributed up and down, the outside of the loading bag 1 is connected to the second Velcro 5, the upper first Velcro 4 and the lower second Velcro 5 are adhered to each other, so that the sealed bag opening 3 is fixed on the loading bag 1, and the first Velcro 4 and the second Velcro 5 have the same size, and the lower part of the sealed bag opening 3 is connected to the drawstring 12. By pulling the sealed bag opening 3 to cover the feeding port of the loading bag 1, and then folding the sealed bag opening 3 and the feeding port of the loading bag 1, the lower first Velcro 4 and the upper second Velcro 5 are adhered to each other.
[0024] First, the staff puts an appropriate amount of adhesive powder into the charging bag 1 so that the adhesive powder contacts the foam sleeve 2, and then seals the feeding port of the charging bag 1. After sealing, the sealing bag opening 3 is pulled to cover the feeding port of the charging bag 1. At this time, the first Velcro 4 on the upper side is separated from the second Velcro 5 on the lower side, and the rotary cover 11 is turned forward to separate from the air outlet pipe 6. Then, the sealing bag opening 3 and the feeding port of the charging bag 1 are folded to make the first Velcro 4 on the lower side and the second Velcro 5 on the upper side adhere to each other, and then the sealing bag opening 3 is fixed on the charging bag 1 to achieve the effect of sealing the feeding port of the charging bag 1, thereby avoiding leakage of the charging bag 1. When the feeding port of the charging bag 1 is folded, the air inside the foam sleeve 2 is squeezed into the outlet. In the air pipe 6, the filter 7 filters the air so that the glue powder in the air stays in the foam sleeve 2, thereby avoiding waste of glue powder. The filtered air is discharged from the one-way valve 8. After folding the feed port of the loading bag 1, the staff continues to press the airbag 10 to deform it, and then draws the air inside the foam sleeve 2 into the air outlet pipe 6 for discharge, thereby avoiding residual air inside the foam sleeve 2. After all the air inside the foam sleeve 2 is extracted, the staff turns the screw cap 11 backward to close the air outlet pipe 6, and repeats the above steps to continue to stack and transport the glue powder. During transportation, the foam sleeve 2 plays a buffering role, reducing the friction between the glue powder and the loading bag 1, and avoiding the glue powder from wearing the loading bag 1.
