Description

Technical Field

[0001] The present invention relates to the technical field related to bottom bulk loading, and in particular to a bottom bulk loading machine provided with a dust collecting mechanism. Background Art

[0002] A bulk loader is a type of packaging equipment. Commonly used bulk loaders include clinker bulk loaders, floor bulk loaders, and side loaders. Floor bulk loaders are primarily used for bulking cement and other powdered materials. They are installed on the ground and are used to load tank containers in vehicles, trains, and other similar applications. Side loaders are primarily used for bulking cement and other powdered materials. They are installed on the side of a cement silo and are used to load tank containers in vehicles, trains, and other similar applications.

[0003] Although the existing bulk loader at the bottom of the silo can collect dust caused by the falling mineral powder in the filling machine, the dust generated after the mineral powder falls into the closed compartment through the filling telescopic pipe cannot be collected. Usually, as the amount of mineral powder injected gradually increases, the dust will escape through the gap between the filling telescopic pipe and the filling port of the closed compartment, which not only pollutes the working environment but also causes waste of resources.

[0004] In order to overcome the above-mentioned defects, reference can be made to the dust collection mechanism of the mineral powder silo bottom bulk loader disclosed in the prior art (application number CN201720072387.0, publication date 2017-08-25). During the filling process, the filling telescopic tube is extended downward and inserted into the filling port on the top of the closed compartment together with the lower dust collecting component. After the mineral powder is separated from the filling telescopic tube and falls into the bottom of the closed compartment, the dust generated during the process is absorbed by the lower dust collecting tube. The structure is simple and can effectively collect the dust generated by the mineral powder falling into the closed compartment through the filling telescopic tube.

[0005] Another example is a bulk loader disclosed in the prior art (application number CN201520418050.1, published on November 18, 2015), which can overcome the dust emission during the loading process of clothing carts, reduce the labor intensity of on-duty personnel, and reduce environmental pollution; and the dust accumulated in the telescopic discharge head can flow back, and the dust accumulation in the telescopic discharge head will not occur;

[0006] At the same time, reference can be made to the prior art (Chinese patent application number CN202221471948.1, published on November 8, 2022) which discloses a dust collecting mechanism for a bulk loader at the bottom of a mineral powder silo. This dust collecting mechanism can spray water out of the water tank, and when rotating, it will increase the spraying range of the water, thereby effectively improving the dust suppression effect.

[0007] Although the existing bulk loader performs subpackaging during bulk loading, a certain amount of powder will remain in the barrel during the bulk loading process. After the staff finishes using it, some of the powder will overflow, which in turn causes dust to overflow.

[0008] Therefore, we proposed a bulk loader with a dust collecting mechanism at the bottom of the warehouse to solve the above problems. Summary of the Invention

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0041] See also Figures 1-11 , the present invention provides the following technical solutions:

[0042] Example 1: In order to facilitate the docking and cutting process, please refer to the attached Figure 1 and attached Figure 2, including a base 1, a dust collecting assembly 2 is installed at one side of the top of the base 1, and the input end of the dust collecting assembly 2 extends into the interior of the fixed cylinder 3, so as to facilitate the collection and treatment of the dust inside the fixed cylinder 3; it also includes: a group of upper connecting cylinders 4 are connected to the outer position of the fixed cylinder 3, and one end of the fixed cylinder 3 passing through the inner position of the base 1 is connected to a stretching tube 5, and the bottom position of the stretching tube 5 is connected to the top position of the bonding disk 6, and the bottom position of the bonding disk 6 is fixed with a lower connecting cylinder 7; the corners around the top of the base 1 are hung at the bottom lower position of the material warehouse by brackets, and valves are provided at the outer positions of the first air pipe 9 and the third air pipe 25. The top position of the upper connecting cylinder 4 is connected to the outlet position of the material warehouse through a flange, and the lower connecting cylinder 7 is conical in shape and inserted into the inlet position of the container. The retractable mechanism includes a telescopic tube 10 connected to the bottom of the first gas pipe 9. A pull ring 11 is fixed to the bottom of the telescopic tube 10. The outer side of the pull ring 11 is embedded in the inner part of a hook ring 12. The bottom of the hook ring 12 is welded to the front and rear sides of the top of the bonding plate 6. The telescopic tube 10 is composed of a thick tube and a thin tube. The thin tube is sealed and slidably installed inside the thick tube. Both the thin tube and the thick tube have gas transmission channels 1001. A conical gasket 1002 is slidably installed at the bottom of the gas transmission channel 1001. The bottom of the conical gasket 1002 is connected to the inside of the thin tube via a return spring 1003. The bottom of the conical gasket 1002 fits into the conical groove. The bottom position of the gas delivery channel 1001 is connected to one end of the second gas delivery pipe 13, and the other end position of the second gas delivery pipe 13 is connected to the inside of the fixed block 14. The bottom position of the fixed block 14 is fixed to the top position of the bonding disk 6. A closed cavity 15 is opened inside the fixed block 14, and a piston 16 is bonded to the bottom end position of the closed cavity 15. The top of the piston 16 is fixed to the bottom position of the spiral sleeve 17. The inner position of the spiral sleeve 17 is spirally connected to the outside of the screw rod 18. The middle position of the screw rod 18 is rotatably set on the outside of the fixed block 14, and the top position of the screw rod 18 is fixed with a rotating gear 19.

[0043] When using the device, first, the base 1 is hung at the bottom of the material warehouse through the brackets at the corners around the top, and the top of the upper connecting tube 4 is connected to the bottom of the material warehouse. After closing the third gas pipe 25 and opening the valve of the first gas pipe 9, the gas supply assembly 8 is then started to allow the first gas pipe 9 connected to the output end of the gas supply assembly 8 to circulate gas. When the gas is transported, the gas will drive the telescopic tube 10 to change its position. At this time, the pull ring 11 fixed at the bottom of the telescopic tube 10 will drive the hook ring 12 to descend. At this time, the hook ring 12 will also drive the fitting plate 6 and the lower connecting tube 7 to change their positions, so that the bottom position of the lower connecting tube 7 fits the inlet position of the container.

[0044] Example 2: In order to solve the problem that the bulk packing machine currently on the market performs subpackaging during bulk packing, but in the process of bulk packing, there will be a certain amount of powder residue in the barrel, and after the staff finishes using it, some of the powder will overflow, which will further cause dust to overflow. Figure 1 -Attached Figure 6 , an air delivery component 8 is fixed at the bottom position of the right end of the base 1, and the output end of the air delivery component 8 is connected to one end position of the first air delivery pipe 9, and the bottom position of the first air delivery pipe 9 is connected to the retractable mechanism, and the bottom position of the retractable mechanism is connected to the outside of the hook ring 12 fixed on the top of the fitting plate 6, and one end of the retractable mechanism is connected to the second air delivery pipe 13. Through the coordinated setting of the retractable mechanism, the limiting mechanism is attached to the outside of the container inlet to avoid the deviation of the lower connecting tube 7 and the overflow of dust; the limiting mechanism includes a rotating gear 19 outside The side is meshed with the outside of the mating gear ring 20, which fixes the top position of the rotating cylinder 21. The bottom position of the rotating cylinder 21 is rotatably mounted inside the bonding disk 6. A conical gear ring 22 is fixed to the outside of the bottom of the rotating cylinder 21. The outer periphery of the conical gear ring 22 is meshed with the outside of the bevel gear 23. The end of the bevel gear 23 is rotatably mounted inside the bonding disk 6 via a support block. The end of the bevel gear 23 is threadedly connected to a limit block 24, and the outer side of the limit block 24 is bonded to the outer side of the container inlet. The middle portion of the limit block 24 is slidably mounted inside the bonding disk 6. Four groups of limit blocks 24 are arranged at equal angles about the center of the rotating cylinder 21. The rotating cylinder 21 is positioned outside the stretch tube 5.

[0045] In addition, when the bottom position of the fitting disk 6 fits in the top position of the container inlet, the telescopic tube 10 will not be able to move in position. The conical gasket 1002 provided inside the telescopic tube 10 is continuously transported by gas, causing the conical gasket 1002 to move in position through the return spring 1003. At this time, the gas inside the gas delivery channel 1001 is transported to the inside of the second gas delivery pipe 13, and is transported to the inside of the fixed block 14 through the second gas delivery pipe 13. In addition, the closed cavity 15 opened inside the fixed block 14 will be filled with gas, and the piston 16 fitted in the inside of the fixed block 14 will move in position, so that the piston 16 drives the spiral sleeve 17 to slide inside the fixed block 14. In addition, the inside of the spiral sleeve 17 has a spiral connection between the outer sides of the spiral rod 18. At this time, the screw rod 18 rotates stably in the internal position of the fixed block 14, and the rotating gear 19 fixed on the top of the screw rod 18 also rotates. At this time, the rotating gear 19 can drive the meshing connection with the matching gear ring 20 to rotate, and the rotating cylinder 21 fixed on the inner side of the matching gear ring 20 rotates in the internal position of the bonding disk 6, and the rotating cylinder 21 fixed at the bottom of the rotating cylinder 21 can also drive the bevel gear 23 to rotate inside the bonding disk 6. Since the end of the limiting block 24 is connected to the rod at the center position of the bevel gear 23 for threaded connection, the limiting block 24 can be moved inside the bonding disk 6. At this time, the outer side of the limiting block 24 can be attached to the outer side of the container inlet, and the purpose of limiting the bonding disk 6 and the lower connecting cylinder 7 is achieved.

[0046] Example 3: In order to fully carry out dust collection, please refer to the attached Figure 7 -Attached Figure 11The vibration mechanism includes a semi-ring block 26 connected to the end of the third air supply pipe 25, the semi-ring block 26 is fixed at the upper position inside the fixed cylinder 3, and a fitting ball 27 is provided inside the semi-ring block 26 for rolling. A moving block 28 is slidingly provided on the inner side of the semi-ring block 26, and the moving block 28 extends out of the semi-ring block 26. One end position of the moving block 28 is connected to the inner position of the semi-ring block 26 through a return spring 29. Two groups of knocking blocks 30 are fixed on one end of the moving block 28 extending out of the semi-ring block 26. A patch 31 is slidingly provided at one end position of the interior of the semi-ring block 26 away from the third air supply pipe 25. The back position of the patch 31 is connected to the inner position of the semi-ring block 26 through a rubber elastic rod 32. A through hole 33 is provided at the bottom position of the patch 31, and an air outlet 34 is provided at the bottom position of the semi-ring block 26. Two sets of vibration mechanisms are installed around the center of the fixed cylinder 3. A semi-annular block 26 is tilted upward. A third air supply pipe 25 is located on one side of the semi-annular block 26 near a contact ball 27. The outer side of the contact ball 27 fits within an annular groove within the semi-annular block 26. The end of the contact ball 27 that contacts the movable block 28 is curved, and the weight of the contact ball 27 is greater than the elastic force of the return spring 29. The bottom of the rotating cylinder 21 fits within the curved groove within the semi-annular block 26. The maximum deformation distance of the rubber elastic rod 32 is the same as the distance the through hole 33 moves to the air outlet 34. The third air supply pipe 25 is connected to the middle of the first air supply pipe 9. The outlet of the third air supply pipe 25 extends into the top of the fixed cylinder 3 and connects to the semi-annular block 26. The vibration mechanism is installed inside the semi-annular block 26. The arrangement of the vibration mechanism and the air outlet mechanism ensures that any material remaining on the inner wall of the fixed cylinder 3 is fully discharged.

[0047] During the unloading process, the valve of the material warehouse is opened, and the material is unloaded through the upper connecting tube 4, the stretching tube 5 and the lower connecting tube 7. When the material remains in the internal position of the fixed tube 3, the valve of the third gas pipe 25 is opened and the valve of the first gas pipe 9 is closed. At this time, the gas will be transported through the third gas pipe 25. At this time, the gas inside the third gas pipe 25 is transported to the inside of the third gas pipe 25. Since the arc groove opened inside the third gas pipe 25 is fitted with a fitting ball 27, the gas will be transported to the inside of the semi-ring block 26 and push the fitting ball 27. At this time, when the fitting ball 27 rolls, the fitting ball 27 will also squeeze one side of the moving block 28, so that the moving block 28 accumulates force through the return spring 29, and the fitting ball 27 no longer squeezes the moving block 28. When the moving block 28 is reset by the return spring 29, the outer side of the knocking block 30 squeezes one side of the spiral sleeve 17, which can make the semi-ring block 26 vibrate, and the fixed cylinder 3 will also vibrate, so that the residual material inside the fixed cylinder 3 will fall, and the dust collecting component 2 will collect the dust inside the base 1. When the bonding ball 27 moves to one side of the patch 31, the patch 31 can squeeze one side of the rubber elastic rod 32. At this time, the patch 31 will move in position, so that the through hole 33 coincides with the air outlet 34. At this time, the gas inside the semi-ring block 26 will be transported through the air outlet 34. At this time, the gas is transported to the inside of the fixed cylinder 3, so that the material can be fully discharged by vibration and blowing, and the dust can be fully collected by the dust collecting component 2.

[0048] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
