Description

Technical Field

[0001] This utility model relates to the field of centrifugal crushing and separating machine technology, specifically to a centrifugal crushing and separating machine. Background Technology

[0002] Centrifugal crushing and separating machines are widely used for crushing and shaping various slags, including metals, non-metallic ores, building materials, and artificial sand. They also possess the unique function of separating two materials that are bonded together. In recent years, the LXF1595 centrifugal crushing and separating machine has been widely used in highway maintenance work to separate asphalt-attached aggregates. After secondary crushing, the asphalt is separated from the aggregates, allowing for efficient recycling and reuse. This transforms previously waste materials into reusable materials, achieving a reuse rate of over 80%-90%. This reduces highway maintenance costs and addresses the issue of rational resource recycling. Therefore, we have designed a centrifugal crushing and separating machine. Utility Model Content

[0003] The purpose of this invention is to provide a centrifugal crushing and separating machine that has the advantage of peeling off the original attached asphalt, thus solving the problem that when crushing stones with attached asphalt, the asphalt cannot be peeled off, making it impossible to centrally recycle and reuse the asphalt.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a centrifugal crushing and separating machine, including a support frame, a discharge pipe installed inside the support frame, a crushing chamber connected to the top of the discharge pipe, a hydraulic cylinder connected to the left side of the crushing chamber, a U-shaped frame connected to the top of the telescopic end of the hydraulic cylinder, a connecting arm rotatably connected to the inner wall of the U-shaped frame, a connecting frame connected to the side of the connecting arm away from the U-shaped frame, a feed hopper connected to the side of the connecting frame away from the connecting arm, the bottom of the feed hopper extending into the interior of the crushing chamber, a main base connected to the bottom of the discharge pipe, support rods connected to the top and bottom of the left and right sides of the inner wall of the main base, a support sleeve connected between the two support rods, a crushing shaft installed through the two support sleeves, a driven pulley fixedly sleeved on the bottom of the outer side of the crushing shaft, mounting frames connected to the left and right sides of the bottom of the support frame, a crushing motor connected to the top of the mounting frame, and a drive pulley fixedly sleeved on the output end of the crushing motor.

[0005] Preferably, the top of the crushing shaft passes through the feed pipe and extends into the interior of the crushing chamber, and a crushing impeller is connected to the top of the crushing shaft. Several liners are installed on the outer side of the inner wall of the crushing chamber.

[0006] Preferably, a transmission belt is fitted around both the driving pulley and the driven pulley, and the vertical height of the driven pulley is twice the vertical height of the driving pulley.

[0007] Preferably, four support legs are installed on the left and right sides of the bottom of the support frame and between the two mounting brackets.

[0008] Preferably, a number of support blocks are connected to the outer side of the top of the crushing chamber, and two adjacent support blocks form a group. A support shaft is installed through the two support blocks. A connecting sleeve is movably sleeved on the outside of the support shaft and between the two support blocks. A damper is connected to the top of the connecting sleeve. The top of the damper passes through the feed hopper and is threaded with a positioning nut. An elastic washer is sleeved on the top of the damper and between the positioning nut and the feed hopper.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] This invention utilizes a support frame, main base, material discharge pipe, crushing chamber, crushing motor, mounting frame, support rod, driven pulley, driving pulley, support sleeve, crushing shaft, and transmission belt in combination. It has the advantage of separating the original attached asphalt. When the crushing motor operates, the driving pulley, driven pulley, and transmission belt work together to drive the crushing shaft to rotate. The high-speed rotation of the crushing impeller generates centrifugal force, causing the material to move at high speed. This allows the material to be crushed by itself, as well as by relative friction and collision between materials against the inner wall of the crushing chamber, ultimately achieving separation. During the crushing process, two materials that are originally bonded together, due to their different hardness and specific gravity, will generate different speeds and kinetic forces under the same centrifugal force, overcoming the resistance of adhesion and separating. Furthermore, when crushing stone with attached asphalt, the asphalt can be separated and adhered to the crushing wall of the crushing chamber, reducing wear and impact on the equipment wall and extending the equipment's service life.

[0016] The top of the crushing shaft 22 passes through the feed pipe 8 and extends into the interior of the crushing chamber 9. A crushing impeller is connected to the top of the crushing shaft 22. Several liners are installed on the outer side of the inner wall of the crushing chamber 9. The liners improve the wear resistance of the crushing chamber 9 and can also impact the material, resulting in better crushing effect.

[0017] A drive belt 23 is fitted around the outside of both the driving pulley 20 and the driven pulley 19. The vertical height of the driven pulley 19 is twice the vertical height of the driving pulley 20. The two driving pulleys 20 rotate in the same direction.

[0018] Four support legs 6 are installed on the left and right sides of the bottom of the support frame 5 and between the two mounting brackets 17; the support legs 6 can provide support for the support frame 5, thereby supporting the support frame 5.

[0019] Several support blocks 14 are connected to the outer side of the top of the crushing chamber 9, and two adjacent support blocks 14 form a group. A support shaft 12 is installed through the two support blocks 14. A connecting sleeve 13 is movably sleeved on the outside of the support shaft 12 and between the two support blocks 14. A damper 11 is connected to the top of the connecting sleeve 13. The top of the damper 11 passes through the feed hopper 1 and is threaded with a positioning nut 15. An elastic washer is sleeved on the top of the damper 11 and between the positioning nut 15 and the feed hopper 1. The damper 11 can be positioned by the positioning nut 15, so that the crushing chamber 9 and the feed hopper 1 are connected.

[0020] During operation, the external control equipment of the centrifugal crusher controls the two crushing motors 16 to run synchronously. With the cooperation of the driving pulley 20, the driven pulley 19, and the transmission belt 23, the crushing shaft 22 rotates. The centrifugal force generated by the high-speed rotation of the crushing impeller caused the material to move at high speed, allowing it to crush itself and also causing relative friction and collision between materials against the inner wall of the crushing chamber 9, ultimately achieving separation. During the crushing process, two materials that are originally bonded together will generate different speeds and kinetic forces under the same centrifugal force due to their different hardness and specific gravity, overcoming the resistance of adhesion and separating. Furthermore, when crushing stone with attached asphalt, the asphalt can be separated and adhered to the crushing wall of the crushing chamber 9, reducing wear and impact on the equipment wall and extending the service life of the equipment.

[0021] In summary, this centrifugal crusher, through the coordinated use of the support frame 5, main unit base 7, discharge pipe 8, crushing chamber 9, crushing motor 16, mounting frame 17, support rod 18, driven pulley 19, driving pulley 20, support sleeve 21, crushing shaft 22, and transmission belt 23, solves the problem that when crushing aggregates with attached asphalt, the asphalt cannot be separated, thus preventing its centralized recycling and reuse.
