Description

Technical Field

[0001] The invention relates to the technical field of building material processing, in particular to a building material recycling and separation mechanism. Background Art

[0002] During or after the construction process, a lot of waste construction materials will be generated. Directly stacking or discarding them will have an impact on the environment and cause a huge waste of resources. Therefore, waste construction materials are usually recycled and reused. Structures such as concrete need to be crushed to reduce the volume of the material and separated.

[0003] The patent publication number is CN117583056A, which is a production equipment for preparing recycled building materials from construction waste. Its structure mainly includes a device shell, and a primary crushing unit for primary crushing of construction waste is arranged on the upper part of the device shell. A conveying adsorption unit and a separation unit for separating iron waste are arranged at the discharge port of the primary crushing unit inside the device shell; the material is crushed by the primary crushing unit to reduce the volume, and the iron waste in the construction waste is removed by the conveying adsorption unit and the separation unit, so as to facilitate the recycling of the iron waste.

[0004] However, the above-mentioned equipment performs a single crushing process through the primary crushing unit, and the crushed materials may be of different sizes. When the iron waste is adsorbed and separated, the larger material is likely to affect the separation effect.

[0044] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0045] Embodiment 1, please refer to the attached drawings, the present invention provides a technical solution:

[0046] A building material recycling and separation mechanism, such as Figure 1 As shown, it includes a cylindrical crushing box 100, a discharge pipe 101 is provided in the middle of the bottom of the crushing box 100, and the bottom surface of the crushing box 100 is inclined toward the discharge pipe 101;

[0047] A feeding device is provided in the middle of the top of the crushing box 100, a fixed cylinder 508 is provided at the center of the upper inner cavity of the crushing box 100, the top of the fixed cylinder 508 is fixedly connected to the bottom of the feeding device, the outer side of the fixed cylinder 508 is rotatably connected to an annular seat 309, and a magnetic separation component is provided at the bottom end of the fixed cylinder 508 and the bottom surface of the crushing box 100;

[0048] A rotating assembly is provided on the inner wall of the crushing box 100 at a position corresponding to the annular seat 309. Four transverse crushing cylinders 300 are evenly arranged along the circumferential direction between the annular seat 309 and the rotating assembly. The center of the inner end of the crushing cylinder 300 is fixedly connected to the annular seat 309 through a connecting column 304, and the lower part of the outer end is fixedly connected to the rotating assembly through a connecting block 305.

[0049] A feed trough 301 is provided in the middle of the top of the crushing cylinder 300, a discharge trough 302 is provided in the middle of the bottom, and a flip-type screening assembly is provided at the bottom of the discharge trough 302. A material crushing assembly is provided inside the crushing cylinder 300, and a crushing drive assembly is provided at a corresponding position on the inner wall of the crushing box 100, and the outer ends of the four material crushing assemblies are all connected to the crushing drive assembly.

[0050] When recycling building materials, the recycled materials are transported to the feeding mechanism through an external conveying device, etc., and after pre-processing, they are fed to both sides of the crushing box 100, so that the materials fall into the two crushing cylinders 300 at the same time, and the four material crushing components are driven simultaneously by the crushing drive component to crush the materials;

[0051] The crushed material falls into the flip screening component through the discharge chute 302, and the flip screening component screens the material, so that the smaller material falls directly onto the magnetic separation component for separation, and the larger material remains in the screening chute 400;

[0052] The annular seat 309 and the four crushing barrels 300 are rotated 90 degrees by the rotating assembly, and the positions of the four crushing barrels 300 and the four flip-type screening assemblies are switched, so that the two flip-type screening assemblies with more materials accumulated can be staggered with the feeding device, and the remaining two crushing barrels 300 and the corresponding flip-type screening assemblies are moved to the lower sides of the feeding device to continue the feeding and primary crushing process;

[0053] The two flip-type screening assemblies offset from the feeding device rotate along the crushing drum 300 and gradually rotate to the top of the crushing drum 300, so that the accumulated larger materials can return to the crushing drum 300 through the feeding trough 301 at the top of the crushing drum 300, and are subjected to secondary crushing treatment by the crushing assembly to ensure the material crushing effect and uniformity of particle size. Then the flip-type screening assembly continues to rotate back to the bottom of the crushing drum 300, so as to return to the bottom of the feeding device again to perform corresponding work.

[0054] The crushed materials fall onto the magnetic separation component, which adsorbs the iron materials and separates them from other materials such as concrete or stone, thereby achieving the purpose of separation.

[0055] The present invention pre-treats the material through a feeding device, and distributes the material to two conveying drums for crushing, thereby reducing the workload of each crushing component, and recovers and re-crushes the material retained after screening by switching the position of the rotating component and flipping the flip-type screening component, thereby improving the material processing effect; the present invention sets a magnetic separation component at the bottom of the crushing box 100 to separate and process fine materials, thereby improving the separation effect and avoiding the influence of excessive volume on magnetic separation.

[0056] Among them, Figure 3 As shown, the material crushing assembly includes two crushing rollers 303 symmetrically and parallelly arranged inside the crushing barrel 300, the crushing rollers 303 are rotatably connected to the crushing barrel 300, and a worm gear 306 is coaxially fixed to one end of the crushing roller 303 close to the side wall of the crushing box 100, the two worm gears 306 are both located on the outside of the crushing barrel 300, and a vertical worm 307 is meshed between the two worm gears 306, the worm 307 is rotatably connected to the outer end of the crushing barrel 300, and a transmission gear 308 is fixed to the top, and the transmission gear 308 is correspondingly connected to the crushing drive assembly.

[0057] The feeding device transports the material to both sides of the inside of the crushing box 100, and the material falls into the two crushing cylinders 300 at the corresponding positions. The transmission gear 308 is driven by the crushing drive assembly, and then the worm 307 drives the worm wheels 306 on both sides to rotate in the direction of the worm 307 at the same time, thereby driving the two crushing rollers 303 to rotate inward at the same time to crush the material.

[0058] Among them, Figure 2 As shown, the crushing drive assembly includes a first ring 103 fixed to the upper part of the inner wall of the crushing box 100, the inner side of the first ring 103 is rotatably connected to the first gear ring 104, the four transmission gears 308 are all meshed with the inner lower part of the first gear ring 104, and the inner upper part of the first gear ring 104 is meshed with the first gear 109, as shown in FIG. Figure 4As shown, the first gear 109 and the transmission gear 308 are staggered in upper and lower positions to avoid affecting the rotation of the crushing tube 300 and other structures. A motor is connected to the top of the first gear 109, and the motor is fixedly connected to the inner wall of the crushing box 100.

[0059] When the crushing assembly is working, the four transmission gears 308 rotate simultaneously through the drive of the motor and the transmission of the first gear 109 and the first gear ring 104, thereby rotating the worm 307 and driving the worm wheels 306 on both sides to rotate in the direction of the worm 307 at the same time, thereby driving the crushing roller 303 to rotate and crush the material, thereby realizing the synchronous driving of the four crushing assemblies through the crushing drive assembly.

[0060] Among them, Figure 3 As shown, the flip screening assembly includes a screening slot 400 located at the bottom of the crushing cylinder 300, a screen 403 is fixed at the bottom end of the screening slot 400, and fixed blocks 402 are symmetrically fixed on both sides of the top, two flip gear rings 401 are symmetrically arranged and rotatably connected on the outer wall of the crushing cylinder 300, and the two sides of the screening slot 400 are fixedly connected to the bottom inner side of the two flip gear rings 401 through the fixed blocks 402, and lifting plates 405 are symmetrically arranged on both sides of the top of the inner cavity of the crushing box 100, and the two lifting plates 405 are respectively located on both sides of the feeding device, as shown in FIG. Figure 5 As shown, the lifting plate 405 is connected to the top surface of the crushing box 100 through the lifting cylinder 406, and a motor and a flip gear 404 are provided on the lifting plate 405, and the flip gear 404 is correspondingly connected to the flip gear ring 401.

[0061] The material crushed in the crushing barrel 300 falls into the screening trough 400 through the discharge trough 302, and is screened by the screen 403, so that larger materials remain in the screening trough 400. Then, when the crushing barrel 300 switches its position and rotates to the bottom of the flip gear 404, the lifting plate 405 is moved down by the lifting cylinder 406, and the flip gear 404 is meshed with the flip gear ring 401. Then, the motor of the flip gear 404 is started, and the screening trough 400 is rotated along the outer wall of the crushing barrel 300 through the transmission of the flip gear 404 and the flip gear ring 401, and the notch of the screening trough 400 is closed by the outer wall of the crushing barrel 300 until the notch gradually moves to the feed trough 301. The screening trough 400 continues to rotate, and the materials accumulated inside it gradually fall into the crushing assembly in the crushing barrel 300 through the feed trough 301, so as to be subjected to secondary crushing treatment by the crushing assembly, and then the screening trough 400 returns to the bottom of the crushing barrel 300 as it rotates.

[0062] The width and length of the notch of the crushing trough 202 are slightly larger than the width and length of the discharge trough 302, and the width and length of the notch of the feed trough 301 are slightly larger than the width and length of the notch of the screening trough 400, so that the material can smoothly pass through the discharge trough 302 into the screening trough 400, and after being turned over, it is discharged from the screening trough 400 and passes through the feed trough 301 into the crushing cylinder 300. Curved plates can be set on both sides of the top of the screening trough 400 to fit the outer wall of the crushing box 100, such as Fig.10 As shown, when the screening trough 400 slightly slides relative to the discharge trough 302, the curved plate can prevent the material from falling out of the screening trough 400.

[0063] Among them, Figure 7 As shown, the magnetic separation assembly includes a circular feed plate 500 rotatably connected to the bottom end of a fixed cylinder 508, a driving structure is provided in the middle of the top surface of the feed plate 500, and the top surface of the feed plate 500 is inclined downwardly outward, and a first annular electromagnet plate 501 is provided on the top of the feed plate 500, as shown in FIG. Figure 6 As shown, the inner bottom surface of the crushing box 100 is provided with an annular second electromagnet plate 102, and the first electromagnet plate 501 and the second electromagnet plate 102 are electrically connected to a power supply and a switch;

[0064] like Figure 6 As shown, a plurality of vertical rods 502 are fixed to one side of the bottom of the unloading plate 500, and an inclined brush rod 503 is commonly fixed to the bottom ends of the plurality of vertical rods 502. The brush rod 503 is parallel to the bottom surface of the crushing box 100 and the second electromagnet plate 102, and the bottom of the brush rod 503 is in contact with the bottom surface of the crushing box 100 and the second electromagnet plate 102 through evenly distributed bristles.

[0065] After the material is crushed, it falls onto the unloading plate 500 and moves downward along the inclined top surface of the unloading plate 500. During the movement, the first electromagnet plate 501 adsorbs the iron material and the like therein, and then the material falls to the bottom surface of the crushing box 100. When it moves along the inclined surface toward the discharge pipe 101, the second electromagnet plate 102 performs secondary adsorption treatment to make the material separation more complete; when the processing is completed and the material is discharged from the crushing box 100, the first electromagnet plate 501 and the second electromagnet plate 102 are powered off, and the unloading plate 500 is rotated by the driving structure. During the rotation, the material on the first electromagnet plate 501 can fall along the unloading plate 500 and fall to the bottom surface of the crushing box 100. At the same time, the brush rod 503 rotates with the unloading plate 500, and the material on the second electromagnet plate 102 is cleaned by the brush rod 503, so that the iron material on the first electromagnet plate 501 and the second electromagnet plate 102 can be discharged, thereby realizing the separation and separate unloading and discharge of the materials.

[0066] Among them, Figure 8As shown, the feeding device includes a feeding box 200 fixed in the middle of the top of the crushing box 100, a crushing trough 202 is fixed at the bottom of the feeding box 200, the bottom end of the crushing trough 202 extends into the crushing box 100, and the top of the fixed cylinder 508 is fixed in the middle of the bottom of the crushing trough 202, two feeding ports 203 are symmetrically arranged on both sides of the bottom of the crushing trough 202, and both sides of the bottom surface of the crushing trough 202 are inclined toward the two feeding ports 203 respectively, and two crushing wheels 204 are symmetrically and parallelly arranged in the crushing trough 202, the crushing wheel 204 is rotatably connected to the crushing trough 202, and a crushing gear 205 is fixed at one end, the two crushing gears 205 are meshed with each other, and the other end of one of the crushing wheels 204 is connected to a motor.

[0067] When building materials are put into the feed box 200, the two crushing wheels 204 are rotated through the drive of the motor and the transmission of the two crushing gears 205, and the building materials are pre-crushed to break up large pieces of materials, which is convenient for subsequent secondary crushing by the crushing assembly. The pre-crushed building materials are discharged along the bottom of the crushing trough 202 to the feed ports 203 on both sides, and enter the crushing cylinder 300 below for subsequent crushing.

[0068] Embodiment 2: The structure of this embodiment is basically the same as that of embodiment 1, except that Figure 2 As shown, the rotating assembly includes a second ring platform 105 fixed on the inner wall of the crushing box 100, and the inner side of the second ring platform 105 is rotatably connected to a rotating ring plate 106. The lower part of the outer end of the crushing barrel 300 is fixedly connected to the inner side of the rotating ring plate 106 through a connecting block 305, and a second gear ring 107 is fixed to the lower outer side of the rotating ring plate 106, and a second gear 108 is meshed on one side of the second gear ring 107. The second gear 108 is connected to a motor, and the motor is fixed to the inner wall of the crushing box 100.

[0069] When it is necessary to switch the positions of the four crushing cylinders 300, start the motor of the second gear 108, and through the transmission of the second gear 108 and the second gear ring 107, the rotating ring plate 106 drives the four crushing cylinders 300 to rotate 90°, thereby switching the positions of the crushing cylinders 300 and the flip-type screening assembly, so that the crushing wheel 204 can perform primary crushing and secondary recovery crushing in turn.

[0070] Embodiment 3: The structure of this embodiment is basically the same as that of embodiment 1, except that Figure 7As shown, the driving structure includes a rotating column 504 fixed in the middle of the top surface of the unloading plate 500, the rotating column 504 is rotatably connected to the inner side of the fixed cylinder 508, and a vertical rotating shaft 505 is fixed at the center, the top of the rotating shaft 505 extends out of the rotating column 504, and a third gear 506 is fixed thereto, a fourth gear 507 is meshed with one side of the third gear 506, the fourth gear 507 is connected to a motor, and the motor is fixed on the inner wall of the fixed cylinder 508, when it is necessary to rotate the unloading plate 500, the motor is started, and through the transmission of the third gear 506 and the fourth gear 507, the rotating shaft 505 drives the rotating column 504 and the unloading plate 500 to rotate, thereby accelerating the falling of materials on the unloading plate 500.

[0071] Embodiment 4: The structure of this embodiment is basically the same as that of embodiment 1, except that Fig. 9 As shown, sealing assemblies are provided at the positions of the two feed ports 203 on both sides of the bottom of the crushing trough 202, and each sealing assembly includes two sealing plates 206 symmetrically arranged and slidably connected to the bottom of the crushing trough 202, and a plurality of limiting wheels 207 are rotatably connected to the positions of the sealing plates 206 at the bottom of the crushing trough 202 corresponding to the positions of the sealing plates 206, and the tops of the limiting wheels 207 are in contact with the bottom surfaces of the sealing plates 206, and a vertical spring plate 208 is fixed to the top of the outer end of the sealing plate 206, and the spring plate 208 is connected to the side wall of the crushing trough 202 through a spring, and electromagnet blocks 209 are respectively fixed at the relative positions of the spring plate 208 and the side wall of the crushing trough 202, and the electromagnet blocks 209 are electrically connected to a power supply and a switch.

[0072] When the four crushing cylinders 300 need to rotate and switch positions, the two electromagnet blocks 209 at the corresponding positions are energized to attract each other, so that the spring plate 208 compresses the spring and drives the sealing plate 206 to move toward the feed port 203. The sealing plates 206 on both sides are closed to close the feed port 203 and suspend feeding. After the position switching of the crushing cylinder 300 is completed, the electromagnet block 209 is powered off, so that the spring plate 208 drives the sealing plate 206 to move outward under the action of the spring, reopens the feed port 203, and limits the position of the sealing plate 206 during movement through the limiting wheel 207, so that the sealing plate 206 always keeps in contact with the bottom of the crushing trough 202.
