Description

Technical Field

[0001] This utility model relates to the field of cement and ore conveying technology, specifically to a cement and ore conveying device. Background Technology

[0002] In the cement production process, crushed cement ore needs to be transported over long distances by conveyor to proceed to subsequent grinding, calcination, and other processes. Currently, most commonly used conveyors are ordinary belt conveyors. However, when transporting crushed cement ore, the following problems exist: cement ore particles have high hardness and sharp edges, causing friction on the conveyor belt and drive shaft during transportation, shortening the equipment's lifespan; a large amount of dust is generated during transportation, causing environmental pollution; cement ore impacts the conveyor belt at the inlet, causing damage; cement ore particles may slip along the sides of the conveyor belt during transport, resulting in low transportation efficiency and requiring regular cleaning.

[0014] The present invention will now be described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0015] Please see Figure 1-5 This utility model provides a technical solution: a cement ore conveying device, including a conveyor 1, a dust cover 4, and a dust removal mechanism. The dust cover 4 is inverted U-shaped and covers the outside of the conveyor 1. The dust removal mechanism includes a dust isolation cover (not shown in the figure) surrounding the material receiving end of the conveyor 1. The dust isolation cover is connected to the discharge port of the crusher, the ground, and the top surface of the dust cover 4 to prevent dust from escaping. A dust collection box 3 is provided on the outside of the dust isolation cover. A partition plate 32 is provided inside the dust collection box 3 to divide the space inside the dust collection box 3 into a dust collection chamber 33 and a clean chamber 34. The dust collection chamber 33 is located below the clean chamber 34. A dust collection chamber 35 is also connected below the dust collection chamber 33. Several through grooves penetrating its thickness direction are opened on the partition plate 32. Several dust collection bags are provided in the dust collection chamber 33, and the open ends of the dust collection bags penetrate through the through grooves into the clean chamber 34. The dust removal chamber 33 is connected to the internal space of the isolation cover through the air inlet pipe 31. The air outlet of the clean chamber 34 is connected to the negative pressure machine 37. The clean chamber 34 is also equipped with a blow pipe. The lower part of the blow pipe is connected to a blow pipe extending into the through groove. The air outlet of the negative pressure machine 37 is connected to the exhaust pipe 38. The exhaust pipe 38 is equipped with a dust detector. The exhaust end of the exhaust pipe 38 is equipped with a solenoid valve. When the crushed cement ore falls from the crusher onto the conveyor 1, a large amount of dust is generated. The negative pressure is created in the dust collector 3 by the negative pressure machine 37. The dust enters the dust collection chamber 33 along with the air through the air inlet pipe 31, preventing the dust from drifting to the outside and polluting the environment. The air enters the clean chamber 34 through the filter bag 36 and is finally discharged into the exhaust pipe 38. After passing the dust detector test, it is discharged into the atmosphere. The dust cannot pass through the filter bag 36. When the dust accumulates on the filter bag 36, a high-speed airflow is sprayed out through the back-blowing pipe 39 to make the dust fall off and slide into the lower dust collection chamber 35. The opening size of the connection between the dust collection chamber 33 and the dust collection chamber 35 gradually decreases from top to bottom, effectively preventing the dust in the dust collection chamber 35 from drifting back into the dust collection chamber 33.

[0016] Several support frames 12 are arranged in a straight array on both sides of the conveyor 1 in the width direction and along the length direction of the conveyor 1. A rotating drum 13 facing the conveyor belt 11 is rotatably arranged on the support frame 12. The rotating drum 13 is inclined and the height of the end near the center of the conveyor belt 11 in the width direction is lower than the height of the other end. Both sides of the conveyor belt 11 in the width direction are bent upward and contact the upper side of the rotating drum 13. By bending both sides of the conveyor belt 11 upwards into an arc shape, the conveyed material can be effectively prevented from falling off both sides of the conveyor belt 11. The rotating drum 13 supports both sides of the conveyor belt 11 to prevent it from returning to its original shape. At the same time, the rotation of the rotating drum 13 can reduce friction and reduce the wear and tear on the conveyor belt 11 and the rotating drum 13.

[0017] A connecting plate 21 is provided on the top surface of the feeding end of the conveyor 1. An inclined plate 22 is hinged on the connecting plate 21. The inclined plate 22 is inclined outward. Support plates 23 located below the inclined plate 22 are provided on both sides of the width direction of the conveyor 1. A support rod 28 is provided between the support plate 23 and the inclined plate 22. The inclined plate 22 increases the material receiving area and also acts as a buffer for the conveyor belt 11, preventing excessive material from impacting and damaging the conveyor belt 11. The support rod 28 reinforces and supports the inclined plate 22, improving its stability.

[0018] A groove 24 is provided on the upper surface of the support plate 23. A slide rod 25 is provided in the groove 24. A slider 26 is slidably provided on the slide rod 25. One end of the support rod 28 is hinged to the slider 26, and the other end is hinged to the inclined plate 22. A spring 27 sleeved on the slide rod 25 is connected between the slider 26 and the groove wall of the groove 24. A limiting block 29 for limiting the maximum displacement of the slider 26 is also provided in the groove 24. When the material impacts the inclined plate 22 to a certain extent, the inclined plate 22 will tilt under the impact to play a buffering role. During the tilting process, the inclined plate 22 will drive the slider 26 to move outward and compress the spring 27. The elastic potential energy of the spring 27 will offset part of the impact. At the same time, the inclined plate 22 can also return to its original state under the action of the spring 27. The limiting block 29 is used to limit the slider 26 to prevent the compression of the spring 27 from exceeding its maximum limit and causing irreversible damage to the spring 27.

[0019] The dust cover 4 includes a plurality of first cover plates 41 and a plurality of second cover plates 43. The bottom surfaces of both ends of the plurality of first cover plates 41 in the length direction are recessed outward to form a first recessed groove 42. The top surfaces of both ends of the plurality of second cover plates 43 in the length direction are recessed inward to form a second recessed groove 44 corresponding to the first recessed groove 42. The first cover plates 41 and the second cover plates 43 are arranged alternately. The first cover plate 41 and the second cover plate 43 are alternately arranged in their length direction. The first recessed groove 42 and the second recessed groove 44 cooperate with each other to make the installation tighter, effectively preventing dust from leaking out from the gaps, and also facilitating installation and disassembly.

[0020] The dust cover 4 has extension plates 45 extending outward from both bottom ends. The extension plates 45 have several through holes 46 along their length. The extension plates 45 increase the contact area between the dust cover 4 and the ground, reduce the pressure, and prevent the dust cover 4 from sinking. The dust cover 4 is fixed by passing pins through and inserting them into the ground.

[0021] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the scope of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
