It includes a crushing box, and a screening mechanism and a crushing mechanism are installed inside the crushing box. The crushing mechanism is located above the screening mechanism, and a feed pipe is fixedly installed on the top of the crushing box; through the cooperation between the mounting frame and spring 1 and the screen plate and the vibrator, the screen plate vibrates to screen the crushed rubber particles, so that the smaller rubber particles fall from the guide frame and the discharge pipe, and through the cooperation between the slide plate and the inner rod and the spring 2 and the connecting rod, the card plate is separated from the card slot and the fixing of the mounting frame and the bottom frame is released, so that the screen plate can be rotated to facilitate the falling of the larger rubber particles on the screen plate, thereby facilitating the collection of rubber particles of different sizes.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] As attached Figure 1-7 A micro-nano rubber particle crushing device shown in the figure comprises a bottom box 1, a crushing box 2 is supported on the top of the bottom box 1, a top cover 3 is installed on the top of the crushing box 2, a feed port 4 is arranged on the top cover 3, a crushing assembly 12 is rotatably installed in the middle of the top cover 3, a water injection assembly 6 is inserted in the crushing assembly 12, a support frame 5 is arranged on the top cover 3, the top of the water injection assembly 6 is connected to the support frame 5, and a driving assembly 7 meshingly connected to the crushing assembly 12 is installed on the support frame 5; A discharge port 8 is provided on one side of the bottom box 1, a discharge assembly 9 is provided inside the bottom box 1, a chiller 10 is installed at the bottom end of the other side of the bottom box 1, the chiller 10 is connected to a water pump 11, and the water pump 11 is connected to the water injection assembly 6.

[0028] In a specific implementation, rubber particles are put into the crushing box 2 through the feed port 4, and the driving component 7 drives the crushing component 12 to operate. The crushing component 12 crushes the rubber particles, and the rubber particles are dispersed upward by the force of the crushing component 12 during crushing, so that the scattered and falling rubber particles can be crushed again, thereby improving the thoroughness of crushing, so that smaller rubber particles can be crushed. At the same time, the water chiller 10 extracts water from the water tank 15 for cooling, and then pumps it into the water injection component 6 by the water pump 11, and then discharges it into the crushing component 12 from the water injection component 6. During the rotation of the crushing component 12, cold water is sprayed from the top of the crushing component 12, so as to be distributed in the crushing box 2. The rubber particles on the outside of the crushing assembly 12 can be lubricated to reduce the friction between the rubber particles and the crushing assembly 12, reduce the heat generation, and effectively cool the rubber particles to avoid adhesion between the rubber particles, so that it is easier to crush them into the required particle size. In the process of water injection, cold water flows upward from the bottom of the crushing assembly 12, which can cool the crushing knives 1204 installed on the crushing assembly 12 to avoid the rubber particles from adhering to the crushing knives 1204. At the same time, the sharpness of the crushing knives 1204 can be guaranteed by reducing the friction between the rubber and the crushing knives 1204, thereby increasing the service life of the crushing knives 1204. In the process of crushing the rubber particles, the rubber particles fall on the first filter plate 13 after being crushed, and the scraper 1205 can flatten the rubber particles so that the particles that meet the specifications can be quickly screened out from the first filter plate 13 and fall into the discharge bin. After the discharge bin passes through the second filter plate 14 to filter the water into the water tank 15, the discharge assembly 9 automatically discharges the crushed rubber particles from the discharge port 8, realizing automatic unloading, being able to work continuously, improving the crushing efficiency, and being able to separate from water, and the separated water can be recycled.

[0029] A discharge bin is disposed at the top of the bottom box 1 , a water tank 15 is disposed at the bottom of the discharge bin, and a filter block is installed at the water pumping end of the chiller 10 , and the filter block is placed in the water tank 15 .

[0030] A first filter plate 13 is provided between the discharge bin and the crushing box 2 , and a second filter plate 14 is provided between the discharge bin and the water tank 15 . The filter holes formed in the first filter plate 13 have a larger aperture than the filter holes formed in the second filter plate 14 .

[0031] In a specific implementation, the first filter plate 13 can filter rubber particles that meet the size, and the second filter plate 14 can filter out the water in the rubber particles.

[0032] A conical cavity is provided between the discharge bin and the discharge port 8 , and the inner diameter of the discharge bin is larger than the inner diameter of the discharge port 8 .

[0033] In specific implementation, when water leaks in the discharge bin, due to the setting of the conical cavity, the height of the bottom end of the discharge port 8 is higher than the bottom end of the discharge bin, so that the water can be concentrated in the discharge bin and filtered from the second filter plate 14 into the water tank 15, thereby preventing water from flowing out of the discharge port 8 and avoiding waste of water resources.

[0035] The crushing assembly 12 includes a rotating drum 1201, a follower gear 1202, a nozzle 1203, a crushing knife 1204 and a scraper 1205. The rotating drum 1201 is rotatably installed on the top cover 3. The follower gear 1202 is installed on the top of the rotating drum 1201. The follower gear 1202 is meshed and connected with the driving gear 703. A plurality of nozzles 1203 are arranged in a ring shape on the top of the rotating drum 1201. A plurality of crushing knives 1204 are installed on the rotating drum 1201 at the bottom of the nozzle 1203. A scraper 1205 is installed at the bottom of the rotating drum 1201.

[0036] The crushing knife 1204 has a spiral structure, and a slope is provided at the bottom of the scraper 1205 , and one side of the slope is consistent with the direction of the blade of the crushing knife 1204 .

[0037] During specific implementation, the first motor 701 is operated to rotate the driving rod 702, so that the driving gear 703 meshes with the driven gear 1202 to rotate, thereby causing the rotating drum 1201 to rotate, so that the crushing knife 1204 crushes the rubber particles as it rotates. Since the crushing knife 1204 has a spiral structure, the piled rubber particles can be transported upward during the rotation of the crushing knife 1204, so that the rubber particles can be circulated and lifted until they are crushed into particles of a required size and then filtered out from the first filter plate 13, thereby improving the crushing efficiency. In combination with the inclined surface at the bottom of the scraper 1205, when the scraper 1205 rotates, the inclined surface has an oblique downward pushing effect on the rubber particles, so that particles that meet the size can be quickly filtered out from the first filter plate 13, avoiding accumulation in the crushing box 2, and also avoiding clogging of the filter holes, thereby improving the screening efficiency, thereby further improving the crushing efficiency of the rubber particles.

[0040] In specific implementation, water in the water tank 15 is drawn by the chiller 10 for cooling and then transported to the water pipe 602 by the water pump 11, and then enters the annular water cavity from the connecting pipe 603, and then is sprayed from each nozzle 1203 into the crushing box 2, so as to cool the rubber particles in the crushing box 2 and prevent the rubber particles from sticking together.

[0041] The discharge assembly 9 includes a second motor 901 , a rotating rod 902 and a spiral conveying blade 903 . The second motor 901 is installed outside the bottom box 1 . The output end of the second motor 901 is connected to the rotating rod 902 . The spiral conveying blade 903 is installed on the rotating rod 902 .
