Detailed Description
The technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings, and it should be understood that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
One embodiment of a storage yard dust suppression apparatus as shown in fig. 1-3 comprises a flexible cover 1 made of a woven cloth of abrasion resistant fibers and a steel truss structure 2. The flexible cover body 1 is provided with a feeding hole and a discharging hole, wherein the feeding hole is correspondingly arranged at the outlet of the blanking hopper 3, the discharging hole is used for outputting materials, the discharging hole extends to a preset distance above the material pile 4 so as to form a relatively closed space above the material pile 4, and the splashing of raised dust during the falling of the materials is reduced as much as possible. Beam structure 2 sets up in the inside of flexible cover body 1, locates the exit position that feed inlet department corresponds blanking fill 3 has the orientation the discharge gate direction extends to make the rectification section 5 of the vertical whereabouts of material and the bearing section 6 with the access connection of rectification section 5, rectification section 5 is straight tube-shape, and bearing section 6 is the frustum form, and the less one end of diameter is connected with rectification section 5, the internal diameter of rectification section 5 is less than the internal diameter of feed inlet to carry out the beam set of certain degree to the material, prevent splashing on a large scale, the internal diameter that bears section 6 is greater than the internal diameter of rectification section 5 plays certain cushioning effect to the whereabouts of material.
In order to adjust the distance between the flexible cover body 1 and the material pile 4 conveniently, a plurality of first connecting rings 7 are arranged on the outer wall of the flexible cover body 1 along the axial direction, as shown in fig. 2 and 3, four first connecting rings 7 are uniformly distributed along the circumferential direction of the flexible cover body 1, a plurality of first connecting rings 7 are arranged at intervals in the axial direction of the flexible cover body 1, four ropes 8 sequentially penetrate through the first connecting rings 7 along the axial direction, one ends of the ropes 8 are fixed with the first connecting rings 7 at the lowest points, the other ends of the ropes are connected with a winch which is arranged on one side of the flexible cover body 1 and serves as a first driving structure 9, under the action of the first driving structure 9, the lengths of the ropes 8 are changed, so that the flexible cover body 1 is stretched or contracted along the axial direction, the distance between the two is kept constant along with the increase of the height of the material pile 4, and the dust suppression.
In order to further accurately control the distance between the flexible cover body 1 and the material pile 4, a distance sensor 10 is further arranged at the discharge port of the flexible cover body 1, the distance sensor 10 is used for monitoring the distance between the surface of the flexible cover body 1 and the surface of the material pile 4 in real time and sending the monitored signal to an external controller in time, the external controller sends an instruction to a first driving structure 9, the first driving structure 9 moves to enable a rope 8 to contract or extend, and therefore the discharge port of the flexible cover body 1 is far away from or close to the surface of the material pile 4.
As shown in fig. 2, the axial length of the beam structure 2 is smaller than the length of the flexible cover 1 when the axial length is adjusted to the minimum, so that the dust suppression effect is ensured, and the equipment cost is reduced.
In order to further prevent that the raise dust is excessive a plurality of shower nozzles 11 still encircle in flexible cover body 1 discharge gate department, shower nozzle 11 locates the bottom of flexible cover body 1, because the material generally can form conical stockpile 4 under the action of gravity, partial material must stretch to the outside of flexible cover body 1 promptly, consequently a plurality of shower nozzles 11 set up and formed round annular fog cover, carries out the omnidirectional to stockpile 4 and sprays. A plurality of second connecting rings 12 are further axially arranged on the outer wall of the flexible cover body 1, the second connecting rings 12 and the first connecting rings 7 are arranged at intervals, a water supply pipe 13 connected with the spray head 11 sequentially penetrates through the second connecting rings 12 to be wound on the outer wall of the flexible cover body, and the water supply pipe and the flexible cover body 1 stretch out and draw back synchronously under the action of a water cable towing device 14.
In order to reduce interference with other equipment operations, the feed inlet of the flexible cover 1 and the inlet of the beam current structure 2 are both connected to a second driving structure 15. The second driving structure 15 is a moving trolley, when the position sensors arranged on the stacker and the scraper conveyor monitor that the two are about to move to the same position, the stacker stops working, the moving trolley drives the flexible cover body 1 and the beam structure 2 to horizontally move to the central root of the stacker, and the flexible cover body 1 and the water supply pipe 13 are all compressed to the minimum length so as to avoid interference.
In order to further improve the dust suppression effect when the space allows, an expansion part with the inner diameter larger than that of the cylindrical main body part is formed at the discharge port of the flexible cover body 1 so as to cover the surface of the material pile 4 as much as possible and prevent the generation of dust.
When materials need to be unloaded, the driving moving trolley drives the flexible cover body 1 and the beam structure 2 to move to the position, opposite to the outlet of the blanking hopper 3, of the bearing section 6 of the beam structure 2, the winch driving rope 8 extends the flexible cover body 1 to the maximum length, the water cable drags the water supply pipe 13 to the maximum length synchronously, then the materials begin to be unloaded, the spray head 11 begins to spray water to the falling materials, the materials vertically enter the interior of the flexible cover body 1 and fall under the guidance of the beam structure 2, and the impact on the inner wall of the flexible cover body 1 is reduced to the maximum extent. Along with the accumulation of materials, when a displacement sensor arranged at the discharge hole of the flexible cover body 1 monitors that the distance between the flexible cover body 1 and the surface of the material pile 4 is smaller than a preset distance, a signal is sent to an external controller, the external controller sends an instruction to a winch and a water cable drags the cable 14, the winch and the water cable drags the cable 14 to move, so that the rope 8 and the water supply pipe 13 contract, and the discharge hole of the flexible cover body 1 is far away from the surface of the material pile 4.
It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications therefrom are within the scope of the invention.
