Description

Technical Field

[0001] The invention relates to the field of belt conveyors, and in particular to a belt conveyor section sealing device. Background Art

[0002] Belt conveyors are suitable for conveying bulk materials and finished products in horizontal and inclined directions. They can also be used for assembly line operations with certain process operations. They have large conveying capacity, low power consumption and wide application. Belt conveyors are continuous conveying machines that use flexible conveying as material carrying and traction components. The conveyor belt rotates around the drive roller and the redirection roller. The upper and lower branches between the two rollers are supported by several rollers. When in use, the material is placed on the conveyor belt, and the friction between the drive roller and the conveyor belt is used to drive the conveyor belt and the material to run. At present, due to the support resistance of the rollers and the installation accuracy, the conveyor belt is prone to vibration and deviation, which will cause the conveyed material to fall off the belt, waste materials and generate dust. In addition, the conveying speed of the belt conveyor itself, the disturbance of the external airflow and the materials on the return belt of the belt will also cause material dust. These dusts will cause workshop environmental pollution and threaten the health of workers. Summary of the invention

[0003] In order to solve the above problems, the present invention provides a belt conveyor section sealing device.

Under the blocking effect, the material will not be scattered from both sides of the conveyor belt 11 due to the vibration or deviation of the conveyor belt 11; a sealing cover plate 14 with an isosceles trapezoidal cross-section is provided between the upper ends of the side brackets 12, and a side sealing plate 15 is connected between the side brackets 12, and the lower end of the side sealing plate 15 extends to the lower support roller 16 of the roller assembly, and the upper end of the side sealing plate 15 is sealed and docked with the edge of the sealing cover plate 14. The sealing cover plate 14 and the side sealing plates 15 on both sides form a relatively closed sealing shell on the outside of the conveyor belt 11, and the sealing shell can prevent the dust generated by transportation from diffusing to the surroundings, and control the dust in the sealing shell and below it, thereby effectively controlling the dust amount in the working environment.

[0016] The tail of the frame is provided with a baffle support 17, to which a material baffle 18 is vertically fixedly connected to the baffle support 17 and blocks the tail of the conveyor belt. A baffle support 17 is provided on one side of the feed port at the rear of the frame, and a material baffle 18 is vertically fixedly connected to the baffle support. The lower end of the material baffle is close to the surface of the conveyor belt at the feed port. The feed port passes through the sealing cover plate upward, and a feed hopper is provided at the upper end of the feed port 302. After the material enters the lower end of the conveyor belt 11 from the feed hopper 302, the material baffle 18 can block the material to prevent the material from slipping from the tail end when it enters the conveyor belt 11. A circular hole is provided in the middle of the baffle support 17, and a vertical long hole 181 is provided at the corresponding position of the material baffle 18. A fixing bolt is installed between the circular hole and the vertical long hole 181, and the vertical long hole 181 can conveniently adjust the height of the material baffle 18.

[0017] The roller assembly includes a transverse roller 191 and two inclined rollers 192 installed on the frame through a roller bracket. The two inclined rollers 192 are symmetrically arranged at both ends of the transverse roller 191. The transverse roller 191 and the two inclined rollers 192 form a V-shaped groove structure. The cross-section of the conveyor belt 11 sleeved in the roller assembly is also V-shaped.

[0018] A long angle iron 201 is fixedly connected between the upper surfaces of the baffle support 121, and the outer end of the flexible baffle 13 is fixedly connected to the inclined side plate of the long angle iron 201 by bolts. The long angle iron 201 can be used to conveniently assemble the flexible baffle 13 to an inclined state so that the lower end of the flexible baffle 13 can be stably pressed against the surface of the conveyor belt 11.

[0019] A square tube 202 is fixedly installed between the upper end surfaces of the several side brackets 12, the side of the sealing cover plate 14 is fixedly connected to the surface of the square tube 202, the upper end of the side sealing plate 15 is fixedly connected to the outer side surface of the square tube 202, and the lower end of the side sealing plate 15 is vertically provided with a folded edge 151 inwardly, and the lower end of the sealing shell formed by the sealing cover plate 14 and the side sealing plate 15 is in an open state. After the sealing shell controls the dust dispersion and generates dust, the dust inside will fall to the lower end of the belt conveyor 01, and the folded edge 151 is used to block the dust and control the falling range of the dust.

[0020] Two channel steel side beams 301 are symmetrically arranged in the middle of the frame, the lower end of the side bracket 12 is fixedly connected to the channel steel side beams 301, the lower support roller 16 of the roller assembly is installed between the two channel steel side beams 301 through the roller support 161, and the lower support roller 16 rolls and supports the conveyor belt 11 below. The frame is tilted and supported by the legs 401 with increasing heights, and the upper ends of the legs are fixedly connected to the channel steel side beams through the connecting seats.

[0021] The working process and principle of the present invention are as follows: start the belt conveyor 01 to tilt and lift the material, and let the material enter the conveying belt 11 from the feed hopper 302 at the bottom thereof. The material will flow downward at the moment it enters the conveying belt 11 (tilted state). At this time, the material baffle 18 blocks the material to prevent the material from sliding off the conveying belt 11. During the process of the material being conveyed forward on the conveying belt 11, the flexible baffles 13 on both sides are pressed against the surfaces on both sides of the conveying belt 11 to form a blocking seal for the material. The material will not fall from both sides of the conveying belt 11 due to the vibration or deviation of the conveying belt 11. During this process, the sealing cover plate 14 and the side sealing plate 15 form a sealed shell on the outside of the conveying belt 11, which effectively controls the dust generated during the conveying process to diffuse outward and control the generation of dust. At the same time, a pipeline can be introduced from the tail of the conveyor to exhaust air outward, so that a slight negative pressure is generated in the sealed shell, and the dust is sucked away and enters the dust removal equipment. After the dust inside the sealed shell is gathered, it will fall down into the recovery container on the ground at the lower end of the belt conveyor 01, and it can be cleaned and recovered regularly.
