The technical result of the alleged group of inventions is to increase the degree of loading of containers at the expense of maximum compaction of granular material, without additional surgery to remove residual air (de-aeration), as well as increasing the degree of tightness in their filling.
Brief description of drawings
The invention is illustrated by drawings, where:
Figure 1 shows the design of the device for filling of soft containers of bulk material (General view).
Figure 3 - General view of the device for sealing of the bulk material.
Figure 4 - section a-a in figure 3.
The implementation of the invention
The startup device of soft containers is in the working state the following.
Support ring 12 and upper (working) platform 9 are aligned with one another and at a distance from each other, and made to move in a vertical plane with the help of lifting mechanism 1. Upper platform 9 raised by hoist 1 on a given height corresponding to the height of soft container). The cylinders 11, acting through the ring 12, and through concentric located elastic elements, which are applied spring 10, rejects pressure release levers open 4, made of different size, inward to ensure passage in a loading mouth of soft containers of 6 different sizes. On the lower reference platform) 7 fit the container 6 and is fixed for the lifting loops 5. Then the upper platform 9 falls into the container 6. Pressure release levers open 4 divorce, deviating in the hinges 2 under the influence of the cylinders 11 and rings 12, stretch the container 6, smoothing wrinkles and giving it a working form. Elastic casing 3, sealed upper end on the platform 9 and the lower the leverage 4, is used to ensure tightness of the boot process and exclusion of dust emissions to the atmosphere.
After completion of these operations is filled with a soft container 6 granular material with seal, using the device, shown in figure 3, which has the ability vertical axial displacement within the working platform 9 and rings 12. In figure 2 the dotted outline 13 boot device relative to the bearing rings and working platform.
The sealing device contains a cylindrical body 14, movable items 15, concentrically located on the outside of the case of 14 and executed with the possibility of vertical travel by hydraulic cylinders 16, fixed to the body 14.
In the wall of the case is made of vertical grooves 17 that the body cavity 14 are four mobile working body of 18, the number of which corresponds to the number of moving parts 15.
Each working body of 18 attached to the corresponding rolling element 15 using the rotary axis 19 and spring-loaded 20 to this element.
In the lower part of the case is made discharge port 22 to push the bulk material out of the body cavity 14, 21 bottom of which is made in the form of a cone for compaction of granular material inside the soft container.
Bulk cargo by gravity, gravitational comes through inside the body cavity 14 until its completion. After that, turn actuator cylinder 16, causing moving parts 15 with located on them working bodies 18 spring 20. Working bodies of 18 when moving moving parts 15 up pressed against the inside wall of the housing 14, ensuring the passage of the bulk material, and the motion moving parts 15 down - take the opposite position blocking the cross-section of the case of 14, thereby pushing the cargo out of the body cavity 14 through discharge port 22, which is in its bottom part, and condensing bulk material inside the cavity soft container. For this is the bottom of the boot device 21, made in the form of a cone. In the process of container filling device for sealing synchronously with the top (working) platform 9, rises above the level of the compacted bulk material, and the compact operation is repeated until the full container load, the load control is performed by weight mechanism 8.
After full loading soft container platform 9 rises, loaded container is replaced by empty and the cycle of operations is repeated.
Due to the fact that the container is not saturated with compressed air and that of bulk cargo "squeezed out" of the device for sealing, not falls by gravity from the height, provides a significant reduction in the emission of dust into the atmosphere, leading to a decrease in energy costs for dust suppression.
