Description

Technical Field

[0001] The invention relates to the technical field of polymer flame retardants, in particular to polymer flame retardant spraying equipment for lignite processing. Background Art

[0002] Since the ignition point of lignite is between 260 and 350 degrees Celsius, it is most likely to spontaneously combust. Therefore, flame retardants are usually sprayed on the surface of the coal before it is transported. At the entrance of the belt for transporting coal, a group of nozzles are set up to add coal flame retardants diluted with water to the lignite. However, the existing spraying of lignite flame retardants still has the following problems:

[0003] The existing lignite flame retardant is usually sprayed on the lignite using multiple nozzles. However, since the lignite is easily piled up on each other when being transported to the belt, the subsequent spraying of the flame retardant can only be sprayed on the surface of the lignite located above, resulting in the flame retardant being unable to be evenly sprayed on the lignite. At the same time, since the bottom of the lignite is in contact with the upper surface of the belt, the flame retardant cannot be sprayed completely on the lignite. Therefore, how to reasonably solve this problem is what we need to consider. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings existing in the prior art, and to propose a polymer flame retardant spraying equipment for lignite processing. When spraying the lignite, the device uses a plurality of abutment bars to shake the abutment belt up and down, and cooperates with a rotating rod to drive a plurality of flip plates to rotate, so as to avoid the accumulation of lignite and cause uneven spraying. At the same time, the flip plate rotates horizontally and longitudinally at the same time, turning the lignite over so that all sides of the lignite can be sprayed with the flame retardant.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: it includes two baffles, and belts are commonly provided on the opposite sides of the two baffles, and the lower ends of the two baffles are fixedly connected to two vertical rods, and the lower ends of multiple vertical rods are commonly fixedly connected to a bottom plate, and multiple first magnetic strips are arranged in the belt, and a horizontal plate is fixedly connected between adjacent surfaces of multiple vertical rods, and multiple second magnetic strips are arranged at the lower end of the horizontal plate, and the upper ends of multiple second magnetic strips are elastically connected to the lower end of the horizontal plate through multiple shaking springs, and the upper end of each of the second magnetic strips is fixedly connected to a push rod, and the upper end of each push rod passes through the horizontal plate, and each push rod is slidably connected to the horizontal plate, and the adjacent surfaces of each first magnetic strip located above and the second magnetic strip are attracted to each other anisotropically.

[0007] Preferably, the reciprocating spring is conductive, and the adjacent surfaces of the second magnetic strip located on the far left and the bottom plate are provided with conductive blocks that cooperate with each other.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Example

[0022] Reference Figure 1-3 A polymer flame retardant spraying device for lignite processing comprises two baffles 1, and belts 2 are commonly provided on opposite sides of the two baffles 1, and the belts 2 are made of elastic material, and the lower ends of the two baffles 1 are fixedly connected to two vertical rods 4, and the lower ends of the plurality of vertical rods 4 are commonly fixedly connected to a bottom plate 20, and a plurality of first magnetic strips 3 are provided in the belt 2, and a horizontal plate 5 is fixedly connected between adjacent surfaces of the plurality of vertical rods 4, and a plurality of second magnetic strips 7 are provided at the lower end of the horizontal plate 5, and the upper ends of the plurality of second magnetic strips 7 are elastically connected to the lower end of the horizontal plate 5 through a plurality of shaking springs 8, and the upper end of each second magnetic strip 7 is fixedly connected to a push rod 6, and the upper end of each push rod 6 penetrates the horizontal plate 5, and each push rod 6 is slidably connected to the horizontal plate 5, and the adjacent surfaces of each first magnetic strip 3 and the second magnetic strip 7 located above are anisotropically attracted to each other.

[0023] Among them, the upper ends of the two baffles 1 are fixedly connected with multiple support rods 10, and the upper ends of the multiple support rods 10 are commonly fixedly connected with a mounting block 11, and the lower end of the mounting block 11 is installed with multiple nozzles 12. A sliding cavity 13 is provided in the mounting block 11, and a sliding mechanism is provided in the sliding cavity 13. The sliding mechanism includes a slider 18 arranged in the sliding cavity 13, and the slider 18 is slidably connected to the inner wall of the sliding cavity 13. The right side of the slider 18 is elastically connected to the right inner wall of the sliding cavity 13 through a reciprocating spring 19, and the reciprocating spring 19 is conductive. The adjacent surfaces of the second magnetic strip 7 located on the far left and the bottom plate 20 are provided with mutually matching conductive blocks 9, and an external power supply can be set. The external power supply, the two conductive blocks 9 and the reciprocating spring 19 form a loop through wires.

[0024] Among them, a rotating rod 14 is vertically provided in the sliding cavity 13, the upper end of the rotating rod 14 is fixedly connected to the inner top of the sliding cavity 13, the outer wall of the rotating rod 14 is fixedly connected to the wire wheel 16, a pull rope is wound around the wire wheel 16, and the end of the pull rope away from the wire wheel 16 is fixedly connected to the left side of the slider 18, the outer wall of the rotating rod 14 is elastically connected to the inner top of the sliding cavity 13 through a torsion spring 17, the lower end of the rotating rod 14 extends to the outside and is provided with two flip plates 15, and the two flip plates 15 are symmetrically fixedly connected to the outer wall of the rotating rod 14.

[0025] The functional principle of the present invention can be explained by the following operation mode: when the lignite is transported on the belt 2, the flame retardant can be pumped out by the existing pump body, and then sprayed onto the lignite on the belt 2 through multiple nozzles 12;

[0026] In the process of conveying lignite by the belt 2, the plurality of first magnetic stripes 3 will continuously approach and move away from the second magnetic stripe 7. When the first magnetic stripe 3 approaches the second magnetic stripe 7, the adjacent surfaces of the first magnetic stripe 3 and the second magnetic stripe 7 are attracted to each other anisotropically, thereby attracting the plurality of second magnetic stripes 7 to move upward, thereby driving the plurality of abutting rods 6 to move upward and abut the belt 2. When the first magnetic stripe 3 moves away from the second magnetic stripe 7, the plurality of second magnetic stripes 7 drive the abutting rods 6 to move back under the elastic action of the shaking spring 8, and the belt 2 moves back under the elastic action of itself.

[0027] The plurality of first magnetic strips 3 are constantly approaching and moving away from the second magnetic strips 7, so that the plurality of second magnetic strips 7 drive the abutting rods 6 to continuously move up and down, thereby intermittently abutting the belt 2, so that the belt 2 is continuously supported and lowered, so that the lignite on the belt 2 will not be piled up together, ensuring that the flame retardant can be sprayed on each lignite;

[0028] At the same time, the second magnetic strip 7 on the left side vibrates up and down, which causes the two conductive blocks 9 to continuously contact and disengage. When the two conductive blocks 9 contact each other, the reciprocating spring 19 is energized. After the reciprocating spring 19 is energized, according to the electromagnetic effect, each coil will generate a magnetic field, and the magnetic fields generated by every two adjacent coils are in opposite directions. Every two adjacent coils will generate mutual attraction, which will cause the reciprocating spring 19 to contract, drive the slider 18 to move right, and thus pull the pull rope. Since the pull rope is located on the wire wheel 16, the wire wheel 16 will drive the rotating rod 14 to rotate, thereby driving the two flip plates 15 to rotate, disturbing the lignite, and further preventing the lignite from piling up.

[0029] When the two conductive blocks 9 are disengaged, the reciprocating spring 19 is de-energized. After the reciprocating spring 19 is de-energized, it moves back under its own elastic action, thereby loosening the pull rope. After the pull rope is loosened, the rotating rod 14 is no longer restricted by the tension, so that the rotating rod 14 moves back under the action of the torsion spring 17, and the pull rope is wound around the reel 16 again, which is convenient for the next use.

[0030] Compared with the prior art, by arranging a plurality of first magnetic strips 3 on the belt 2, the operation of the belt 2 will continuously bring the plurality of first magnetic strips 3 close to and away from the second magnetic strip 7, so that the second magnetic strip 7 drives the stopper 6 to move up and down to shake the belt 2, thereby avoiding the accumulation of lignite and ensuring that the flame retardant can be sprayed on each lignite;

[0031] The up and down movement of the second magnetic strip 7 causes the two conductive blocks 9 to continuously come into contact and separate, causing the slider 18 to move left and right. As a result, under the action of the torsion spring 17, the rotating rod 14 drives the two flip plates 15 to reciprocate, thereby disturbing the lignite on the belt 2 and further improving the effect of spraying the flame retardant on the lignite. Example

[0032] Reference Figure 4-5 The difference between this embodiment and embodiment 1 is that a vertical cavity 22 is provided in the rotating rod 14, and a piston 23 is provided in the vertical cavity 22. The piston 23 is slidably connected to the inner wall of the vertical cavity 22, and a rack 24 is fixedly connected to the lower end of the piston 23. A cross bar 26 is horizontally provided in the vertical cavity 22, and the two ends of the cross bar 26 are rotatably connected to the left and right inner walls of the vertical cavity 22. A gear 25 matching the rack 24 is fixedly connected to the cross bar 26, and the rack 24 and the gear 25 are meshed with each other. The two ends of the two cross bars 26 extend to the outside and are fixedly connected to the opposite surfaces of the two flip plates 15. The top space of the vertical cavity 22 is connected to the left space of the sliding cavity 13 through the air inlet pipe 21. The two flip plates 15 are rotatably connected to the rotating rod 14 in this embodiment, the bottom space of the vertical cavity 22 is connected to the outside through a short tube, and the left space of the sliding cavity 13 is connected to the outside through a through port.

[0033] In this embodiment, during the movement of the slider 18 to the left and right, since the slider 18 is sealed and slidably connected to the inner wall of the sliding chamber 13, the leftward movement of the slider 18 will reduce the left space of the sliding chamber 13 and increase the air pressure. At this time, the gas in the left space of the slider 18 enters the top space of the vertical chamber 22 through the air inlet pipe 21, so that the piston 23 drives the rack 24 to move downward. When the slider 18 moves to the right, the left space of the sliding chamber 13 increases and the air pressure decreases. At this time, the gas in the top space of the vertical chamber 22 enters the left space of the sliding chamber 13 through the air inlet pipe 21, and the piston 23 moves upward, that is, the left and right movement of the slider 18 drives the piston 23 to move up and down.

[0034] The up and down movement of the piston 23 drives the rack 24 to move up and down, thereby causing the gear 25 to reverse, and then drives the cross bar 26 and the two flip plates 15 to rotate, so that the two flip plates 15 can turn the lignite over, so that each side of the lignite can be sprayed with the combustion agent.

[0035] Compared with the prior art, the left and right movement of the slider 18 drives the piston 23 to move up and down, so that the rack 24 moves up and down to drive the two flip plates 15 to rotate longitudinally, turning the lignite over so that all sides of the lignite can be sprayed with flame retardant.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
