Description

Technical Field

[0001] The present invention belongs to the technical field of construction, and more specifically, particularly relates to a magnetic separation device for construction waste in construction. Background Art

[0002] Construction refers to the production activities in the implementation stage of project construction, which is the construction process of various buildings. It can also be said to be the process of turning the various lines on the design drawings into physical objects at a specified location. It includes foundation engineering construction, main structure construction, roofing engineering construction, decoration engineering construction, etc. Construction is the production activity in which people use various building materials and construction machinery and equipment to build various building products according to a specific design blueprint within a certain space and time. It includes the entire production process from construction preparation, breaking ground to project completion acceptance. In this process, construction preparation, construction organization design and management, earthwork engineering, blasting engineering, foundation engineering, steel bar engineering, formwork engineering, scaffolding engineering, concrete engineering, prestressed concrete engineering, masonry engineering, steel structure engineering, wood structure engineering, structural installation engineering, etc. will be carried out. Many waste materials in construction waste can be reused as renewable resources after sorting, removing and crushing;

[0003] However, the existing magnetic separation devices for construction waste in construction still have the following deficiencies when in use:

[0004] 1. The feeding link lacks an effective control mechanism, resulting in easy accumulation of construction waste during feeding. This not only makes it difficult for the waste to be evenly spread on the conveyor belt and difficult to fully contact the magnetic separation device, causing missed suction of iron-containing impurities and greatly reducing the magnetic separation effect, but also may lead to unstable operation of the equipment and increase the risk of equipment failure;

[0005] 2. During the long-term operation of the equipment, the conveyor belt is extremely vulnerable to damage due to the attachment of impurities. Due to the lack of a convenient cleaning device, the accumulation of impurities not only affects the normal operation of the conveyor belt but also accelerates the wear of the conveyor belt. Frequent replacement of the conveyor belt not only increases the maintenance cost but also reduces the working efficiency of the equipment. Summary of the Invention

[0006] In order to solve the above technical problems, the present invention provides a magnetic separation device for construction waste in construction to solve the above problems.

[0011] Preferably, strip-shaped grooves are opened on the side walls of the feeding boxes, and mounting frames are fixedly installed on the side walls of the feeding boxes.

[0012] Preferably, a driving motor is fixedly installed on the side wall of the mounting frame, and a semi-gear is fixedly installed on the output shaft of the driving motor.

[0013] Preferably, a feeding plate is slidably installed inside the inclined groove.

[0015] Preferably, a rack is fixedly installed on the side wall of the sliding bar, second springs are fixedly installed on both side walls of the sliding bar, and the ends of the two second springs away from the sliding bar are fixed in the inner wall of the strip-shaped groove.

[0016] Preferably, a diversion plate is fixedly installed between the two mounting plates, and the diversion plate is located between the first conveyor belt and the second conveyor belt.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] In the present invention, by providing a first conveyor belt, a feeding box, an inclined chute, a strip-shaped groove, a driving motor, a semi-gear, a feeding plate, a sliding bar, a rack and a second spring, the driving motor will drive the semi-gear to rotate. When the semi-gear rotates to the meshing state with the rack, the rack will be stressed and move horizontally. At this time, the rack will drive the sliding bar to slide inside the strip-shaped groove, and the sliding bar will drive the feeding plate to slide inside the inclined chute. At this time, the two second springs will be compressed accordingly. When the semi-gear rotates to the misaligned state with the rack, the two second springs will restore their deformation, thereby driving the rack and the sliding bar to slide back to the initial position. At this time, construction waste can be put into the feeding box. At this time, under the reciprocating sliding of the feeding plate, the construction waste will be gradually leveled, and then fall onto the first conveyor belt through the gap between the feeding plate and the feeding box. Since the distance between the feeding box and the first conveyor belt is fixed, the paving thickness of the construction waste will also be fixed, making it difficult for the construction waste to accumulate during feeding. The paved construction waste can fully contact the first conveyor belt, and it is not easy to cause the phenomenon of iron-containing impurities leaking and being sucked, enhancing the magnetic separation effect of the equipment;

[0019] In the present invention, by providing a first conveyor belt, a second conveyor belt, a first collection box, a second collection box, a scraping bar and a diversion plate, during operation, the first conveyor belt will convey the construction waste to the left. At the same time, the iron-containing impurities in the construction waste will be adsorbed by the first conveyor belt, and the construction waste will fall into the diversion plate and be collected in the first collection box through the diversion of the diversion plate. The iron-containing impurities will be conveyed along the first conveyor belt and then contact the scraping bar. At this time, the scraping bar will scrape off the iron-containing impurities on the first conveyor belt and make them fall on the second conveyor belt. At this time, start the second conveyor belt, and the iron-containing impurities will be conveyed to the right and fall into the second collection box for collection, enabling the equipment to automatically classify and collect construction waste and iron-containing impurities in the construction waste during use;

[0020] In the present invention, by providing a first conveyor belt and a scraping bar, when the first conveyor belt is contaminated with impurities after long-term use, it will contact the scraping bar under the continuous transmission of the first conveyor belt. The scraping bar can clean the impurities adhered to the first conveyor belt. And when scraping, the first spring will slightly deform to adjust the position of the scraping bar, making it not easy for the scraping bar to have hard contact with the first conveyor belt and cause damage to it, enhancing the service life of the equipment;

[0021] In the present invention, by providing a first slot, a second slot, a first collection box, a first plug, a second collection box and a second plug, by respectively installing the first plug and the second plug on the first collection box and the second collection box, during installation, the first plug and the second plug can be respectively aligned with the first slot and the second slot and inserted, making the overall installation of the first collection box and the second collection box more convenient and labor-saving.

The two first insertion blocks 18 and the second insertion blocks 21 are respectively slidably installed in the two first slots 13 and the second slots 14. By respectively installing the first insertion blocks 18 and the second insertion blocks 21 on the first collection box 17 and the second collection box 19, during installation, the first insertion blocks 18 and the second insertion blocks 21 can be respectively aligned with the first slots 13 and the second slots 14 and inserted, making the overall installation of the first collection box 17 and the second collection box 19 more convenient and labor-saving;

[0031] A central bar 22 is fixedly installed between the two mounting plates 12. Symmetrically arranged sliding grooves 23 are opened inside the central bar 22. A scraping bar 24 is slidably installed inside the sliding grooves 23. First springs 25 are symmetrically and fixedly installed inside the inner wall of the scraping bar 24. One end of the two groups of first springs 25 away from the scraping bar 24 is fixedly connected to the central bar 22. When impurities adhere to the first conveyor belt 15 after long-term use, at this time, under the continuous transmission of the first conveyor belt 15, it will contact the scraping bar 24. The scraping bar 24 can clean the impurities adhering to the first conveyor belt 15. And when scraping, the first springs 25 will slightly deform to adjust the position of the scraping bar 24, so that the scraping bar 24 is not likely to make hard contact with the first conveyor belt 15 and cause damage to it, enhancing the service life of the device;

[0032] At the upper ends of both mounting plates 12, feeding bins 31 are fixedly installed. An inclined slot 32 is penetrated and opened inside the feeding bin 31. A strip-shaped slot 33 is opened on the side wall of the feeding bin 31. An installation frame 34 is fixedly installed on the side wall of the feeding bin 31. A driving motor 35 is fixedly installed on the side wall of the installation frame 34. A semi-gear 36 is fixedly installed on the output shaft of the driving motor 35. A feeding plate 37 is slidably installed inside the inclined slot 32. A slide bar 38 is fixedly installed on the side wall of the feeding plate 37. The slide bar 38 is slidably installed in the strip-shaped slot 33. A rack 39 is fixedly installed on the side wall of the slide bar 38. Second springs 41 are fixedly installed on both side walls of the slide bar 38. One ends of the two second springs 41 far from the slide bar 38 are both fixed in the inner wall of the strip-shaped slot 33. A drainage plate 42 is fixedly installed between the two mounting plates 12. The drainage plate 42 is located between the first conveyor belt 15 and the second conveyor belt 16. During use, the driving motor 35 can be started first. Under the action of the driving motor 35, the semi-gear 36 will be driven to rotate accordingly. When the semi-gear 36 rotates to the meshing state with the rack 39, at this time, the rack 39 will be stressed and move horizontally. At this time, the rack 39 will drive the slide bar 38 to slide inside the strip-shaped slot 33. At this time, the slide bar 38 will drive the feeding plate 37 to slide inside the inclined slot 32. At this time, the two second springs 41 will be compressed accordingly. And when the semi-gear 36 rotates to the misaligned state with the rack 39, at this time, the two second springs 41 will recover their deformation, and then drive the rack 39 and the slide bar 38 to slide to the initial position. At this time, construction waste can be put into the feeding bin 31. At this time, under the reciprocating sliding of the feeding plate 37, the construction waste will be gradually leveled, and then fall onto the first conveyor belt 15 through the gap between the feeding plate 37 and the feeding bin 31. Since the distance between the feeding bin 31 and the first conveyor belt 15 is fixed, the paving thickness of the construction waste will also be fixed, so that the construction waste is not likely to accumulate during feeding.

At the same time, the iron-containing impurities in the construction waste will be adsorbed by the first conveyor belt 15, and the construction waste will fall into the drainage plate 42 and be collected in the first collection box 17 after being drained by the drainage plate 42. The iron-containing impurities will be conveyed along the first conveyor belt 15 and then contact the scraping bar 24. At this time, the scraping bar 24 will scrape off the iron-containing impurities on the first conveyor belt 15 and make them fall on the second conveyor belt 16. At this time, the second conveyor belt 16 is started, and the iron-containing impurities will be conveyed to the right and fall into the second collection box 19 to be collected, so that the equipment can automatically classify and collect the construction waste and the iron-containing impurities in the construction waste when in use.

[0033] Working principle:

[0034] First step, when in use, the driving motor 35 can be started first. Under the action of the driving motor 35, the semi-gear 36 will be driven to rotate accordingly. When the semi-gear 36 rotates to the meshing state with the rack 39, at this time, the rack 39 will be stressed and move horizontally. At this time, the rack 39 will drive the slide bar 38 to slide inside the strip-shaped groove 33. At this time, the slide bar 38 will drive the feeding plate 37 to slide inside the inclined groove 32. At this time, the two second springs 41 will be compressed accordingly. When the semi-gear 36 rotates to the misaligned state with the rack 39, at this time, the two second springs 41 will restore their deformation, and then drive the rack 39 and the slide bar 38 to slide to the initial position. At this time, construction waste can be put into the feeding box 31. At this time, under the reciprocating sliding of the feeding plate 37, the construction waste will be gradually leveled, and then fall onto the first conveyor belt 15 through the gap between the feeding plate 37 and the feeding box 31. Since the distance between the feeding box 31 and the first conveyor belt 15 is fixed, the paving thickness of the construction waste will also be fixed, so that the construction waste is not easy to accumulate during feeding. The paved construction waste can fully contact the first conveyor belt 15, and it is not easy to cause the phenomenon of leakage and suction of iron-containing impurities, enhancing the magnetic separation effect of the equipment;

[0035] Second step, at this time, start the first conveyor belt 15. The first conveyor belt 15 will convey the construction waste to the left. At the same time, the iron-containing impurities in the construction waste will be adsorbed by the first conveyor belt 15, and the construction waste will fall into the diversion plate 42 and be collected in the first collection box 17 through the diversion of the diversion plate 42. The iron-containing impurities will be conveyed along the first conveyor belt 15 and then contact the scraping bar 24. At this time, the scraping bar 24 will scrape off the iron-containing impurities on the first conveyor belt 15, making them fall on the second conveyor belt 16. At this time, start the second conveyor belt 16, and the iron-containing impurities will be conveyed to the right and fall into the second collection box 19 for collection, so that the equipment can automatically classify and collect the construction waste and the iron-containing impurities in the construction waste during use;

[0036] Third step, when impurities adhere to the first conveyor belt 15 after long-term use, at this time, under the continuous transmission of the first conveyor belt 15, it will contact the scraping bar 24. The scraping bar 24 can clean the impurities adhering to the first conveyor belt 15. And when scraping, the first spring 25 will slightly deform to adjust the position of the scraping bar 24, so that the scraping bar 24 is not easy to have a hard contact with the first conveyor belt 15 and cause damage to it, enhancing the service life of the equipment;

[0037] Fourth step, by installing the first insertion block 18 and the second insertion block 21 on the first collection box 17 and the second collection box 19 respectively, during installation, the first insertion block 18 and the second insertion block 21 can be respectively aligned with the first slot 13 and the second slot 14 and inserted, making the overall installation of the first collection box 17 and the second collection box 19 more convenient and labor-saving.
