Description

Technical Field

[0001] The invention relates to the technical field of recycling construction waste, and in particular to a recycling device for mixed construction waste materials. Background Art

[0002] With the continuous construction and development of cities, a large amount of construction raw materials is needed. In the process of increasing buildings, a large amount of construction waste will be generated accordingly. Therefore, the generated construction waste needs to be recycled. Among them, the mixed construction waste contains many different raw materials. When recycling construction waste, it will first be classified. After a series of operations, different raw materials such as metals, wood and concrete blocks will be recycled. Among them, when metals are classified, they need to be crushed first, and then the metal objects are collected by magnetic separation after crushing.

[0003] Magnetic separation usually uses a magnetic separator, which uses the attraction of the magnetic field to metal particles to separate metal from non-metallic particles. However, after the magnetic separator separates the metal, some concrete slag and other non-magnetic materials will still remain on the metal surface. Therefore, the separated metal objects need to be additionally processed. Currently, metals are usually cleaned physically or chemically. Physical cleaning usually requires the use of a brush or sandpaper to polish the metal surface, while chemical cleaning requires the use of a detergent to clean the metal objects. Although the above cleaning methods can separate metal objects from concrete slag, physical cleaning is not only slow, but also inefficient in processing large amounts of metal and concrete residues. Chemical cleaning may cause corrosion to the metal surface, affecting the recovery quality and reuse value of the metal objects. Therefore, a new type of construction waste mixed material recycling equipment is needed to solve the above problems. Summary of the invention

[0039] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0040] Please refer to Figure 1 , provides a construction waste mixed material recycling equipment, including a frame 1, a trough body 2 is fixedly installed on the frame 1, a magnetic separation device 3 is rotatably provided on the trough body 2, the trough body 2 and the magnetic separation device 3, the space between the trough body 2 and the magnetic separation device 3 is a separation area, one side of the trough body 2 is a feeding chamber, and the other side is a discharging chamber, a scraper plate 4 is vertically installed on the inner wall of the other side of the trough body 2, and two groups of material boxes 7 for aggregate are plugged into the bottom end of the other side of the trough body 2. In this embodiment, the specific composition and specific principle of the magnetic separation device 3 are the existing technology well known in the art, so they will not be described in detail here.

[0041] Please refer to Figure 1-10 Two groups of switchable magnetic components are provided in the discharge chamber, each group of magnetic components includes an outer frame 11 and an electromagnetic rod group 12 installed on the outer frame 11, the electromagnetic rod group 12 includes multiple groups of electromagnetic rods, and there is a certain distance between the multiple groups of electromagnetic rods, wherein a support frame 13 is provided at the bottom of each group of outer frames 11, and slide bars 14 are fixed at the bottom of both ends of each group of support frames 13, and slideways 15 compatible with the slide bars 14 are provided on the front and rear inner walls of the discharge chamber, and the slide bars 14 are slidably connected in the corresponding slideways 15, and the slideways 15 are inclined in design, and a switching mechanism is provided between the two groups of slide bars 14 on the same side, so that the two groups of magnetic components can be used alternately through the switching mechanism.

[0042] Specifically, the switching mechanism includes two groups of inclined rods 21. The ends of the two groups of sliding rods 14 on the same side away from the support frame 13 are fixed with inclined rods 21. Multiple groups of tooth blocks 22 are fixed below the sides where the two groups of inclined rods 21 are close to each other. A gear 23 adapted to the tooth block 22 is rotatably connected to the slot body 2 through a bearing. Through the mutual cooperation of the inclined rod 21, the tooth block 22 and the gear 23, the magnetic attraction component located above moves downward through the corresponding slideway 15 after carrying a certain weight, and the gear 23 is controlled to rotate through the cooperation of the inclined rod 21 and the tooth block 22, thereby controlling the magnetic attraction component located below to rise. There are two groups of inclined limiting rods 24, the inclination angle of the limiting rods 24 is consistent with that of the inclined rods 21, and a first slider 25 is fixed to the side of the inclined rods 21 close to the limiting rods 24. A slide groove 241 is provided on the inner wall of each group of limiting rods 24 away from the trough body 2, and the first slider 25 is slidably connected in the slide groove 241. A first spring 26 is welded between the first slider 25 and the inner wall of the slide groove 241. After the metal objects collected on the magnetic absorption component below are cleaned up, the elasticity of the first spring 26 can pull the magnetic absorption component below to rise along the trajectory of the slideway 15 to the middle part of the slideway 15 for standby (refer to the attached manual). Fig. 9 ), when the upper magnetic component moves down after bearing a certain weight, the lower magnetic component can rise in time, and there will be no large gap in the middle when the two groups of magnetic components are alternating, thereby avoiding the need to shut down and switch the equipment during the collection of metal objects, thereby improving the collection efficiency to a certain extent.

[0043] It is worth noting that an infrared transmitter is fixedly installed on the side of each group of outer frames 11 away from the magnetic separation equipment 3, and when the magnetic attraction component descends to the lowest point of the slide 15, a corresponding infrared receiver is installed on the inner wall of the trough body 2 at a position flush with the infrared transmitter. At this time, the infrared receiver can receive the infrared light beam emitted by the infrared transmitter and send a signal to the control device, thereby controlling the electromagnetic rod group 12 to cut off the power. After the electromagnetic rod group 12 is powered off, the electromagnetic rod group 12 will be demagnetized. At this time, the metal objects collected on the surface of the electromagnetic rod group 12 can fall into the corresponding material box 7 for collection. When the magnetic attraction component rises to the middle part of the slide 15 after cleaning, the infrared transmitter is away from the infrared receiver, and the electromagnetic rod group 12 can continue to be powered on to perform normal magnetic attraction work.

[0044] Please refer to Figure 11-14A locking mechanism is provided between the support frame 13 and the slot body 2, and the locking mechanism includes a fixing block 31, wherein the fixing block 31 is provided with four groups, and the four groups of fixing blocks 31 are symmetrically fixed to the front and rear inner walls of the other side of the slot body 2, and are respectively located above the highest point of the slideway 15, and a limiting groove 34 is provided in the fixing block 31, and a locking block 32 is inserted in the limiting groove 34, and a second spring 33 is welded between the locking block 32 and the limiting groove 34, and the inner walls at both ends of the support frame 13 are provided with slots 131 for inserting the locking block 32, wherein the bottom of the locking block 32 and the tops at both ends of the support frame 13 are both inclined designs, and the inclined design The support frame 13 can be made to abut against the inclined surface at the bottom of the locking block 32 during the upward movement, so that when the magnetic attraction component located below is switched to the highest point of the corresponding slide 15 for use, the support frame 13 abuts the locking block 32 and shrinks into the limit groove 34, and when the magnetic attraction component reaches the highest point of the slide 15, the locking block 32 is again inserted into the slot 131 opened on the inner wall of the two ends of the support frame 13 under the control of the second spring 33, so that the magnetic attraction component can self-lock its position after rising to the corresponding height, so that the magnetic attraction component can be automatically put into use without manual operation.

[0045] Among them, a buffer unlocking mechanism is provided between the support frame 13 and the outer frame 11, and the buffer unlocking mechanism is used to release the lock between the support frame 13 and the locking block 32. The buffer unlocking mechanism includes an abutting block 41 slidably connected in each group of slots 131, one end of the abutting block 41 and one end of the locking block 32 inserted in the slot 131 abut each other, and the other end of the abutting block 41 abuts with an extrusion block 43, and the end of the extrusion block 43 abutting with the abutment block 41 are both inclined. The abutment block 41 reciprocates in the slot 131 through the third spring 42, and the extrusion block 43 vertically penetrates the chamber 132 opened in the support frame 13, and the chamber 132 is connected to the slot 131. A vertical rod 44 is fixed on the top of the extrusion block 43, and a fourth spring 45 is wound around the vertical rod 44. Both ends of the spring 45 are welded between the vertical rod 44 and the support frame 13. A buffer rod 46 is also passed through the support frame 13. The top of the buffer rod 46 is fixed to the outer frame 11. A fifth spring 47 is wound around the buffer rod 46. Both ends of the fifth spring 47 are respectively welded between the outer frame 11 and the support frame 13. As more and more metal objects are adsorbed on the surface of the electromagnetic rod group 12, the surface weight of the electromagnetic rod group 12 increases. At this time, the outer frame 11 can control the third spring 42 to contract. As the outer frame 11 continues to move downward, the top of the extrusion block 43 can be squeezed, and the extrusion block 43 can be controlled to squeeze the abutment block 41 to move in the slot 131, thereby pushing out the locking block 32, releasing the fixation of the magnetic attraction component position, so that the magnetic attraction component can move down along the slide 15 under the action of its own gravity.

[0046] It is worth mentioning that a movable block 411 is fixed to the bottom of the abutment block 41, and the movable block 411 is slidably connected to a track opened on the inner wall of the support frame 13, and a third spring 42 is welded between the inner wall of the track and the outer wall of the movable block 411. When the magnetic attraction component moves down to the bottom along the slide 15 for cleaning, as the metal objects on the surface of the electromagnetic rod group 12 fall into the corresponding material box 7, the fifth spring 47 can be reset at this time, and control the outer frame 11 and the electromagnetic rod group 12 to rise again. When the outer frame 11 and the electromagnetic rod group 12 rise, the fourth spring 45 drives the vertical rod 44 and the extrusion block 43 to reset, and the abutment block 41 can be reset again under the elastic action of the third spring 42 to abut against the extrusion block 43, wherein a stop block is fixed at the bottom of the buffer rod 46 to prevent the buffer rod 46 from detaching from the support frame 13.

[0047] During use, when a certain weight of metal objects are accumulated on the surface of the upper magnetic component, the outer frame 11 and the electromagnetic rod group 12 will slowly move downward. When the outer frame 11 contacts the top of the vertical rod 44, the vertical rod 44 controls the extrusion block 43 to move downward and compresses the fourth spring 45. At this time, the extrusion block 43 can squeeze the abutment block 41 to move, and the movement of the abutment block 41 can push the locking block 32. When the locking block 32 is pushed to leave the slot 131, the upper magnetic component can move downward with the slide 15. At the same time, after the cleaning of the lower magnetic component is completed, it has been pulled to the middle position of the corresponding slide 15 for standby through the elastic control of the first spring 26. Therefore, when When the magnetic attraction component located at the top moves downward, the inclined rod 21 controls the movement of the corresponding tooth block 22 and causes the gear 23 to rotate. With the rotation of the gear 23, the magnetic attraction component located below can be controlled to quickly rise to the highest point of the corresponding slide 15. Moreover, when it is above the magnetic attraction component below to the highest point of the slide 15, during the upward movement of the support frame 13, the inclined surface of the support frame 13 can abut against the inclined surface of the locking block 32, and control the locking block 32 to compress the second spring 33 and return to the limiting groove 34 again. When the support frame 13 stops moving, the locking block 32 can be inserted into the slot 131 opened on the inner wall at both ends of the support frame 13 under the control of the second spring 33, so as to lock the position of the magnetic attraction component.

[0048] Please refer to Figure 15-16A vibrating screen mechanism is also provided in the discharge chamber, and the vibrating screen mechanism includes a vibrating screen plate 5. Support frames are fixed on both sides of the bottom of the vibrating screen plate 5, and rollers 51 are rotatably connected to the support frames through a rotating shaft. Cams 52 are slidably contacted at the bottom of the rollers 51. A shaft 53 is fixed between the two groups of cams 52. One end of the shaft 53 passes through the trough body 2. A motor 54 is installed outside the trough body 2 through a bracket. The output end of the motor 54 is fixed to one end of the shaft 53 through a coupling, and the other end of the shaft 53 is rotatably connected to the trough body 2 through a bearing. A limiting mechanism is provided between the inner wall, the vibrating screen plate 5 and the scraper plate 4, and the limiting mechanism includes a second slider 55 fixed on the outer wall of the vibrating screen plate 5, and the second slider 55 can move within a limited position in a sliding groove 56 provided on the inner wall of the scraper plate 4, and a sixth spring 57 is welded to the bottom of the second slider 55, and the other end of the sixth spring 57 is welded in the sliding groove 56. By utilizing the cooperation between the vibrating screen mechanism and the limiting mechanism, the vibrating screen plate 5 is controlled to move up and down so as to vibrate and screen the metal objects magnetically separated to distinguish concrete slag from metal objects.

[0049] During use, when the motor 54 controls the shaft 53 and the cam 52 to rotate, the vibrating screen plate 5 can move downward in the trough body 2, and at the same time the second slider 55 slides in the sliding groove 56, and the sixth spring 57 contracts. After the vibrating screen plate 5 moves downward, as the cam 52 continues to rotate, the vibrating screen plate 5 vibrates up and down, thereby shaking off the metal objects in the material and the concrete slag mixed in the metal objects, which is convenient for the subsequent collection of the metal objects, and the shaken concrete slag can fall into the corresponding material box 7 for collection.

[0050] It is worth noting that a guide plate 6 is fixed above the inner wall on the other side of the trough body 2, and the guide plate 6 is inclined toward the scraper plate 4. The design of the guide plate 6 can be used to guide the material so that the material falls vertically.

[0051] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
