Description

Technical Field

[0001] The utility model relates to the technical field of dust removal equipment, in particular to a dust collecting device for unloading powder materials on a train. Background Art

[0002] At present, when trains loaded with powder materials are unloading, a large amount of dust will be generated at the bottom. There are two common ways to deal with the dust. One is to build a closed unloading shed at the unloading point to prevent the dust from spreading outward. However, the problem is that the direction of the train entering and exiting cannot be sealed, which will still cause the dust to spread outward. At the same time, if the dust scattered in the unloading shed cannot be cleaned up in time, it will cause secondary dust. The second is to use a dust suppression spray device to spray water mist on the drop point to prevent the dust from spreading outward. However, the liquid sprayed by the dust suppression spray device will affect the material properties and is not conducive to the collection of materials.

[0003] The Chinese patent with application number CN202122711521.6 discloses a split-type mobile dust removal device for a train unloading warehouse, including a left movable cover and a right movable cover that are arranged in a mirror image, wherein the two faces of the left movable cover and the right movable cover that are opposite to each other are both open, and the other faces are all closed; the left movable cover and the right movable cover can both independently perform negative pressure dust suction, and the movable cover and the right movable cover can both move so that the movable cover and the right movable cover are sealed and closed. By moving the left movable cover and the right movable cover relative to each other, the left movable cover and the right movable cover are closed and sleeved on the transferred train materials, thereby forming a relatively sealed space on the transferred train materials, and then performing negative pressure dust removal through the space independently formed by the left movable cover and the right movable cover, which not only has a low cost, but also reduces the power required for negative pressure dust removal, saves energy, reduces the size of wind force, and reduces the discomfort of operators.

[0004] However, the above mobile dust removal device is very inconvenient to use. When the plant is being built, the investment cost is too high, the equipment size is large, and when the equipment fails, it is not easy to repair. Utility Model Content

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Depend on Figures 1 to 5 The invention discloses a transport carriage 2 which moves on a supporting platform 1, wherein the supporting platform 1 is provided with rails on which the transport carriage 2 moves. The supporting platform 1 is provided with a collecting hopper 3 located below the transport carriage 2, and a storage bin can be provided below the collecting hopper 3. The transport carriage 2 discharges materials into the storage bin through the collecting hopper 3. A bag dust collector 4 is provided on one side of the transport carriage 2. The bag dust collector 4 is a prior art and will not be described in detail herein. A centrifugal fan 5 is provided at one end of the bag dust collector 4, and a dust collecting pipe is fixed at the other end of the bag dust collector 4. The dust collecting pipe includes a main pipe 6 connected to the bag dust collector 4. A branch pipe 7 is connected to one side of the top of the main pipe 6, and the transport carriage 2 is located between the main pipe 6 and the branch pipe 7. The bottoms of the main pipe 6 and the branch pipe 7 are respectively connected to a plurality of equally spaced branch pipes 8. A horn cover 9 is fixed to one end of the plurality of branch pipes 8 close to the transport carriage 2. Through the arrangement of the centrifugal fan 5, the bag dust collector 4 and the dust collecting pipe, the horn cover 9 is aligned with the unloading side of the transport carriage 2. The centrifugal fan 5 is started, and the raised dust enters the dust collecting pipe under negative pressure and finally enters the bag dust collector 4. The overall structure is simple and effective, and the construction cost is reduced as much as possible while meeting the dust removal and dust suppression effect, so that the overall dust removal equipment has higher universality;

[0028] If the distance between the horn cover 9 and the transport compartment 2 is fixed, then for different widths of the transport compartment 2, the effect of the horn cover 9 on dust removal and dust suppression will be discounted, and some dust will escape, reducing the use effect of the equipment. The branch pipe 8 includes a fixed pipe 10 and a movable pipe 11, and an accordion cover 12 is fixed between the fixed pipe 10 and the movable pipe 11. Flanges are fixed on the movable pipe 11 and the fixed pipe 10 respectively, and at least three circumferentially evenly distributed connecting rods 13 are fixed on the flange of the movable pipe 11. This arrangement is to ensure the levelness of multiple movable pipes 11 during movement. The accordion cover 12 is stable and will not swing. The connecting rod 13 also serves as a protection for the accordion cover 12. The connecting rod 13 passes through the flange of the fixed tube 10 and is slidably connected thereto. A receiving plate 14 is fixed on the middle movable tube 11. A horizontal electric push rod 15 is fixed on the supporting platform 1. The output end of the electric push rod 15 is fixedly connected to the receiving plate 14. Through the arrangement of the fixed tube 10, the movable tube 11 and the connecting rod 13, workers can directly control the extension and retraction of the electric push rod 15 for transport compartments 2 of different widths, adjust the distance between the speaker cover 9 and the transport compartment 2, and improve the flexibility of the overall equipment.

[0029] refer to Figure 5 to Figure 6 As shown, in order to increase the adjustment degree of the horn cover 9, form a certain angle between the horn cover 9 and the carrying compartment 2, and improve the dust removal efficiency, a spherical compensator 16 is provided at one end of the movable pipe 11 away from the accordion cover 12. The spherical compensator 16 is a prior art and will not be described in detail here. The horn cover 9 is fixedly connected to the rotating end of the spherical compensator 16, and connecting plates 17 are fixed on the branch pipes 8 on both sides. A slide cylinder 18 is fixed on one side of the bottom of the connecting plate 17. A piston rod 19 is slidably connected in the slide cylinder 18. The piston rod 19 is connected to the slide cylinder 18 through a spring. A connecting frame 20 is fixed to the bottom of the horn cover 9. Slide grooves 21 are provided on both sides of the connecting frame 20. A slide rod 22 is fixed to one end of the piston rod 19 close to the slide groove 21. The slide rod 22 slides in the slide groove 21. In the initial state, the spring is in a compressed state, and the piston rod 19 and the slide rod 22 hold the horn cover 9 to make the horn cover 9 in a vertical state.

[0030] A support rod 23 penetrating the connecting plate 17 is fixed to one end of the piston rod 19, and a fixed plate 24 located on the supporting platform 1 is fixed to the end of the support rod 23 away from the piston rod 19. Through the spherical compensator 16, the connecting plate 17 and the piston rod 19, when the electric push rod 15 drives the movable tube 11 to move toward the transport compartment 2, the support rod 23 and the piston rod 19 are in a stationary state. As the movable tube 11 moves, the spring is continuously compressed, and the pull rod also drives the horn cover 9 to deflect inward, with a maximum deflection angle of 15°. This arrangement allows the horn cover 9 to have a higher dust absorption efficiency.

[0031] refer to Figure 7 As shown, in order to further enhance the flexibility of the speaker cover 9, an adjustment plate 25 is fixed to the end of the support rod 23 away from the piston rod 19, and a plurality of waist-shaped grooves 26 arranged up and down are opened on the adjustment plate 25, and the lengths of the plurality of waist-shaped grooves 26 decrease step by step. A vertical plate 27 located on one side of the adjustment plate 25 is fixed to the support platform 1, and a plurality of adjustment holes 28 are opened on the vertical plate 27, which are matched with the waist-shaped grooves 26, respectively. An adjustment pin 29 is inserted in one of the adjustment holes 28, and the adjustment plate 25 and the waist-shaped grooves 26 are adjusted to adjust the speaker cover 9. The groove 26 and the vertical plate 27 are arranged, and the adjusting pin 29 is inserted into different adjusting holes 28 and waist-shaped grooves 26. Due to the different lengths of the waist-shaped grooves 26, when the adjusting pin 29 is inserted in the longest waist-shaped groove 26, the electric push rod 15 moves one meter and the horn cover 9 deflects 5°. When the adjusting pin 29 is inserted in the shortest waist-shaped groove 26, the electric push rod 15 moves one meter and the horn cover 9 deflects 15°. Workers can insert the adjusting pin 29 into the corresponding adjusting hole 28 according to actual needs, thereby further improving the flexibility of the equipment and the dust removal and dust suppression efficiency.

[0032] In order to facilitate the adjustment of the air volume in the multiple branch pipes 8, the multiple fixed pipes 10 are provided with air regulating valves, which are prior art and will not be described in detail here.

[0033] In order to ensure the sealing of the accordion cover 12 and prevent air leakage, the accordion cover 12 is a metal accordion cover 12.

[0034] When the utility model is used:

[0035] First, the carriage 2 moves to the top of the hopper 3, the centrifugal fan 5 is started, the carriage is opened to unload, and the material is guided by the hopper 3 to enter the storage bin downward, and the raised dust is guided by the horn cover 9 and the branch pipe 8 to enter the bag dust collector 4;

[0036] Then, for the transport compartment 2 of different widths, the worker can directly control the extension and contraction amount of the electric push rod 15 to adjust the distance between the speaker cover 9 and the transport compartment 2;

[0037] Secondly, when the electric push rod 15 drives the movable tube 11 to move toward the direction of the transport compartment 2, the support rod 23 and the piston rod 19 are in a stationary state. As the movable tube 11 moves, the spring is continuously compressed, and the pull rod also drives the horn cover 9 to deflect inward, with a maximum deflection angle of 15°. This arrangement allows the horn cover 9 to absorb dust more efficiently;

[0038] Finally, insert the adjusting pin 29 into different adjusting holes 28 and waist-shaped grooves 26. Since the lengths of the waist-shaped grooves 26 are different, when the adjusting pin 29 is inserted in the longest waist-shaped groove 26, the electric push rod 15 moves one meter and the horn cover 9 deflects 5°. When the adjusting pin 29 is inserted in the shortest waist-shaped groove 26, the electric push rod 15 moves one meter and the horn cover 9 deflects 15°. The workers can insert the adjusting pin 29 into the corresponding adjusting hole 28 according to actual needs.
