Description

Technical Field

[0001] The present invention relates to the technical field of air separation equipment, and more specifically, to an air separation device for urban domestic waste. Background Art

[0002] The modernization of industry has led to the large-scale development of enterprises. Large-scale development requires efficient, high-capacity and energy-saving equipment, and the same is true for waste sorting and treatment. Efficient and high-quality waste sorting and treatment can improve social benefits, bring economic benefits, and achieve environmental protection goals. The most commonly used technology for existing waste treatment is the comprehensive waste treatment method, which separates recyclable and reusable materials through mechanical or manual sorting, and treats the remaining materials in a targeted manner; among them, the winnowing machine is one of the main separation equipment in mechanical sorting. It mainly separates light materials in the garbage, such as plastics, for combustion and power generation. Therefore, the separation efficiency of the winnowing machine is a relatively important part of waste sorting.

[0003] A Chinese patent with the authorization publication number CN214052562U discloses a new type of domestic waste air separator, which can ensure the normal operation of the fan circulation system through the circulating air outlet. When the amount of domestic waste to be processed is large, on the one hand, the wind pressure at the adjustable air inlet can be increased by increasing the frequency of the centrifugal fan; on the other hand, the negative pressure inside the bellows can be adjusted by connecting the air induced device to the spare air outlet; thereby achieving the purpose of air separation of excess domestic waste.

[0004] Although this new type of domestic waste air classifier can achieve air classification of excess domestic waste, during the waste sorting process, the heavy waste on the conveyor line is easily entangling with the light waste to form a complex mixture. Specifically, the heavy waste may be wrapped in the light waste, or pressed on the surface of the light waste, which increases the difficulty of separation. When the light and heavy waste are air-separated, it is very easy for this part of the light waste to be mistakenly discharged from the heavy discharge port, affecting the sorting effect.

An impact block 301 is fixedly installed on the upper end of the transmission column 302. A fixed block 314 is arranged on the upper side of the ejection knife 312. The fixed block 314 is fixedly connected to the inner wall of the inner cavity 26, and a spring 2 315 is fixedly installed between the fixed block 314 and the ejection knife 312.

[0034] A fan 11 is fixedly installed on the upper end surface of the outer frame 1, and a blast pipe 12 is connected between the fan 11 and the outer frame 1. A discharge pipe 13 is connected to the right end surface of the outer frame 1. A conveying device 14 is arranged on the lower inner side of the outer frame 1. A motor 15 is fixedly installed on the left end surface of the outer frame 1, and a gear 16 is fixedly installed on the end of the output shaft of the motor 15.

The conveying member 2 is provided with multiple groups of gears 22, which are meshed with each other, and one group of gears 22 is meshed with gear 16.

[0035] First, the pre-treated domestic waste is conveyed into the outer frame 1 through the conveying device 14. Before the domestic waste enters, the motor 15 is started so that the output shaft of the motor 15 drives the gear 16 to rotate. The gear 16 is meshed with the gear 22 fixedly installed at one end of one group of rotating tubes 21, and the gears 22 on each group of rotating tubes 21 are meshed with each other. Therefore, the multiple groups of rotating tubes 21 rotate synchronously, and the turntable 25 fixedly installed on the outer surface of the rotating tube 21 rotates synchronously. When the turntable 25 carries the internal groups of components to rotate to the upper side of the protruding rod 23, the impact block 1 301 on the transmission column 302 will collide with the protruding rod 23 and cause the transmission column 302 to descend. The transmission column 302 synchronously carries the rack 303 to descend, and the rack 303 is meshed with the gear 3 308. The gear three 308 is meshed with the gear four 310, so the gear four 310 and the gear three 308 rotate synchronously, and the gear four 310 is meshed with the teeth 313 on the outer surface of the spring knife 312, so the spring knife 312 will quickly pop out counterclockwise around the fixed column three 311, and then bounce up the light and heavy mixed garbage being transported on the turntable 25, and the steel blades fixedly installed on both sides of the outer surface of the spring knife 312 will synchronously cut the light garbage wrapped around the outer surface of the heavy garbage. As the turntable 25 continues to rotate, the impact block 1 301 and the protruding rod 23 move away from each other. At this time, the transmission column 302 returns to its original position under the action of the spring 1 306, and at the same time cooperates with the spring 2 315 to make the spring knife 312 return to its original position synchronously, so as not to affect the normal operation of the adjacent turntable 25.

[0036] A vibrating member 4 is provided inside the ejection assembly 3, and the vibrating member 4 includes an inner cavity 2 410 opened inside the ejection knife 312, a gear ring 401 is provided inside the inner cavity 2 410, and the gear ring 401 is fixedly installed on the outer surface of the fixed column 3 311. A fixed shaft 1 402 is provided on one side of the gear ring 401, and the fixed shaft 1 402 is rotatably connected to the inner cavity 2 410. A gear 5 403 is fixedly installed on the outer surface of the fixed shaft 1 402, and the gear 5 403 is meshed with the gear ring 401.

[0037] A fixed shaft 2 404 is arranged on the front side of the fixed shaft 1 402 , and the fixed shaft 2 404 is rotatably connected to the inner wall of the inner cavity 2 410 . A belt 405 is sleeved between the outer surface of the fixed shaft 2 404 and the outer surface of the fixed shaft 1 402 , and the belt 405 is transmission-connected thereto.

[0038] A cam 406 is fixedly installed on the outer surface of the fixed shaft 404, a cross bar 407 is provided on the lower side of the cam 406, and a plurality of groups of impact blocks 408 are fixedly installed on the lower end surface of the cross bar 407. One end of the impact block 408 extends to the outside of the inner cavity 410, and the impact block 408 is slidably connected to the spring knife 312. A spring 3 409 is fixedly installed between the cross bar 407 and the inner wall of the inner cavity 410.

[0039] When the spring knife 312 deflects around the fixed fixed column three 311, it will synchronously carry the displacement of various groups of internal components. The gear five 403 fixedly installed on the outer surface of the fixed shaft one 402 is meshed with the gear ring 401 fixedly installed on the outer surface of the fixed column three 311, so the fixed shaft one 402 rotates synchronously. The fixed shaft one 402 and the fixed shaft two 404 are connected by the belt 405 transmission, so the fixed shaft two 404 will carry the cam 406 to rotate. The rotation of the cam 406 will hit the cross bar 407, and cooperate with the spring three 409 provided on the cross bar 407 to make the cross bar 407 reciprocate. The multiple groups of impact blocks two 408 fixedly installed on the cross bar 407 reciprocate synchronously, and along with the collision of the spring knife 312 with the light and heavy garbage, they are vibrated synchronously, and then the heavy garbage is vibrated and separated, thereby accelerating the separation of light and heavy garbage.

[0040] The light and heavy garbage separation component also includes an injection component 5 arranged inside the turntable 25, and the injection component 5 includes a curved pipe 501 fixedly installed inside the inner cavity 410, and a piston plate 503 is slidably connected inside the curved pipe 501. A curved rod 502 is fixedly installed between the spring knife 312 and the piston plate 503, and the curved rod 502 is slidably connected to the curved pipe 501.

[0041] An airbag 504 is fixedly installed between the piston plate 503 and the inner wall of the bent pipe 501, a connecting cavity 505 is opened inside the bent rod 502, the airbag 504 is connected with the inner cavity 410 through the connecting cavity 505, the lower end surface of the airbag 504 is connected with an input pipe 506, and the outer surface of the spring knife 312 is opened with multiple groups of spray holes 507, and the multiple groups of spray holes 507 are symmetrically opened on both sides of the impact block 408.

[0042] At the same time, when the ejection knife 312 rotates counterclockwise, it will synchronously carry the curved rod 502 to move, and the piston plate 503 at the other end of the curved rod 502 will slide and move inside the curved tube 501, thereby squeezing the airbag 504, so that the gas inside the airbag 504 enters the interior of the inner cavity 2 410 through the connecting cavity 505, and is ejected from the nozzle on the ejection knife 312 along with the ejection knife 312, so that the light and heavy garbage are separated and the separation is accelerated by the wind.

[0043] The ejection assembly 3 includes a closure member 6 arranged inside the inner wall of the turntable 25, and the closure member 6 includes a slide rail 601 arranged on one side of the transmission column 302, the slide rail 601 is fixedly connected to the inner wall of the inner cavity 410, and a piston plate 602 is slidably connected inside the slide rail 601, and the piston plate 602 is fixedly connected to the transmission column 302, and an airbag 603 is fixedly installed between the piston plate 602 and the inner wall of the slide rail 601.

[0044] A storage chamber 605 is provided inside the turntable 25, a connecting tube 604 is provided between the storage chamber 605 and the airbag 2 603, one end of the storage chamber 605 is connected to the slot 316, a closing plate 606 is slidably connected inside the storage chamber 605, and a slot 607 is provided on the outer surface of the closing plate 606 corresponding to the bent rod 502.

[0045] Secondly, when the transmission column 302 descends, it will carry the piston plate 2 602 to slide inside the slide rail 601. The piston plate 2 602 will squeeze the airbag 2 603. The gas inside the airbag 2 603 will enter the storage chamber 605 through the connecting pipe 604, and push out the closing plate 606 inside the storage chamber 605, sealing the gap generated when the spring knife 312 bounces up, thereby preventing fine particles in the garbage from entering the inside of the turntable 25 and affecting the normal operation of the equipment.

[0046] During the garbage sorting process, the heavy garbage on the conveyor line is easily entrained with the light garbage to form a complex mixture. Specifically, the heavy garbage may be wrapped in the light garbage, or pressed on the surface of the light garbage, which increases the difficulty of separation. When the light and heavy garbage are separated by air, it is very easy for this part of the light garbage to be mistakenly discharged from the heavy discharge port, affecting the sorting effect. Therefore, this scheme sets up a light and heavy garbage separation mechanism. When the turntable 25 conveys the garbage, the ejector 312 will contact the garbage and separate the light garbage entrained on the outer surface of the heavy garbage. At the same time, the vibrating component is used to crush the heavy garbage to a certain extent, thereby accelerating the separation of the light and heavy garbage. An additional jet component 5 is provided to perform vertical jetting, and cooperate with the ejection component 3 and the vibrating component to accelerate the separation of the light and heavy garbage.

[0047] Instructions for use: First, the pre-treated domestic waste is conveyed into the interior of the outer frame 1 through the conveying equipment 14.

When the turntable 25 carries the internal groups of components to rotate to the upper side of the protruding rod 23, the impact block 1 301 on the transmission column 302 will collide with the protruding rod 23 and cause the transmission column 302 to descend. The transmission column 302 synchronously carries the rack 303 to descend, and the rack 303 meshes with the gear 3 308. The gear 308 is meshed with the gear 4 310, so the gear 4 310 and the gear 308 rotate synchronously, and the gear 4 310 meshes with the teeth 313 on the outer surface of the spring knife 312, so the spring knife 312 will quickly pop out counterclockwise around the fixed column 311, and then bounce up the light and heavy mixed garbage being transported on the turntable 25, and the steel blades fixedly installed on both sides of the outer surface of the spring knife 312 will synchronously cut the light garbage wrapped around the outer surface of the heavy garbage. As the turntable 25 continues to rotate, the impact block 1 301 and the protruding rod 23 move away from each other. At this time, the transmission column 302 returns to its original position under the action of the spring 1 306, and at the same time cooperates with the spring 2 315 to make the spring knife 312 return to its original position synchronously, so as not to affect the normal operation of the adjacent turntable 25;

[0048] Secondly, when the spring knife 312 deflects around the fixed fixed column three 311, it will synchronously carry the displacement of various groups of internal components.

[0049] At the same time, when the ejection knife 312 rotates counterclockwise, it will synchronously move the curved rod 502, and the piston plate 1 503 at the other end of the curved rod 502 will slide and move inside the curved tube 501, thereby squeezing the airbag 1 504, so that the gas inside the airbag 1 504 enters the interior of the inner cavity 2 410 through the connecting cavity 505, and is ejected from the nozzle on the ejection knife 312 along with the ejection knife 312, so that the light and heavy garbage are separated and the separation is accelerated by the wind.

[0050] Secondly, when the transmission column 302 descends, it will carry the piston plate 2 602 to slide inside the slide rail 601. The piston plate 2 602 will squeeze the airbag 2 603. The gas inside the airbag 2 603 will enter the storage chamber 605 through the connecting pipe 604, and push out the closing plate 606 inside the storage chamber 605, sealing the gap generated when the spring knife 312 bounces up, thereby preventing fine particles in the garbage from entering the inside of the turntable 25 and affecting the normal operation of the equipment.
