[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0019] See also Figures 1-6 as well as Figure 10 The present invention provides a technical solution: a complete set of equipment for removing impurities and cleaning concrete mortar recycled from construction solid waste, comprising a feed hopper 1 and a material selection trough 4; a receiving trough 2 is installed at the bottom of the feed hopper 1, and a material selection trough 4 is installed at one end of the receiving trough 2. The receiving trough 2 and the material selection trough 4 are internally movably connected with a screw shaft 201 for spiral feeding, and a plurality of water-permeable holes are opened on the surface of the screw shaft 201 to facilitate the reciprocating flow of water in the receiving trough 2 and the material selection trough 4; the front and rear ends of the screw shaft 201 near the material selection trough 4 are connected to a bracket 8, and a thin-walled gear ring 801 is fixed to the outside of the bracket 8, a water collecting bin 5 is fixed under the material selection trough 4, a scum cover 6 is fixed on the top of the material selection trough 4, and slag discharge channels 601 are connected to both sides of the scum cover 6.

[0020] During specific implementation, the crushed construction solid waste is introduced into the receiving trough 2 along the feed hopper 1. Since the upper layer of the selection trough 4 is provided with a scum cover 6 above the liquid surface, when debris enters the selection trough 4, the debris floating on the upper layer of the liquid surface will be concentrated in the scum cover 6, and then the rotating spiral shaft 201 drives the bracket 8 and the thin-walled gear ring 801 to rotate. When rotating, the thin-walled gear ring 801 can engage with the two sets of transmission gears 703 on the upper side, thereby driving the two scraping shafts 702 to rotate.

[0021] See also Figures 1-10 , the interior of the scum cover 6 is provided with a debris removal mechanism 7 for removing solid waste floating debris in the water, and the debris removal mechanism 7 includes two scraping shafts 702 symmetrically distributed on the inner side of the scum cover 6, and transmission gears 703 meshing with the thin-walled gear ring 801 are fixed at both ends of the scraping shaft 702, and a direction adjustment seat 704 is connected to one of the scraping shafts 702, and adjusting wheels 705 are installed on both sides of the scraping shaft 702 close to the slag discharge channel 601, and a cross arm 709 is placed on the upper part of the circumferential side of the adjusting wheel 705. The two ends of the cross arm 709 are slidably connected to a push-pull arm 707 driven back and forth by the adjusting wheel 705, and the push-pull arm 707 is also provided with a scooping plate 711 for scooping up the upper debris on the water surface; A motor 712 is mounted on one end of the top wall of the scum cover 6 . A bearing seat is mounted on one end of the top wall of the scum cover 6 . A brush rod 713 is connected to the bearing seat and docked with the output end of the motor 712 .

[0022] In specific implementation, when the scooping plate 711 on the toggle member 710 is flipped forward from the suspended placement to the horizontal placement, the scooping plate 711 will scoop up the large debris floating on the upper layer of the water surface, and finally lift the debris horizontally to the upper side of the scum cover 6. At this time, the motor 712 drives the brush rod 713 to rotate to clean and sweep the debris away from the water surface; when the scooping plate 711 on the toggle member 710 is flipped back from the horizontal placement to the suspended placement, the scooping plate 711 will be reset to the suspended placement angle to facilitate subsequent scooping of debris, ensuring that the impurity removal and cleaning equipment can efficiently remove debris floating on the upper layer of the water surface during the process of washing and sorting debris.

[0023] See also Figure 5-Figure 9 , the two parallel scraping shafts 702 are movably connected with a clamping seat 701, one end of the clamping seat 701 is fixed to the inner wall of the scum cover 6; the adjustment seat 704 is installed on the inner wall surface of the scum cover 6, and the inner wall of the circumferential side of the adjustment seat 704 is connected to a reversing bevel gear 7041, and the axial ends of the interior of the adjustment seat 704 are provided with driving bevel gears 7042 that mesh with the reversing bevel gear 7041, and the two driving bevel gears 7042 are respectively fixed with a front shaft and a rear shaft arranged coaxially; One of the scraper shafts 702 is divided into a front shaft body, a middle scraper paddle and a rear shaft body by two adjusting seats 704. The front shaft end of the scraper shaft 702 and the rear shaft end of the scraper shaft 702 are respectively fixed to the front shafts of the driving bevel gears 7042 of the two adjusting seats 704, and the two ends of the middle scraper paddle of the scraper shaft 702 are respectively fixed to the rear shafts of the driving bevel gears 7042 of the two adjusting seats 704. When the front shaft body and the rear shaft body of the scraper shaft 702 with the adjusting seat 704 are rotating forward, the meshing transmission of the two driving bevel gears 7042 and the reversing bevel gear 7041 can make the middle scraper paddle rotate in opposite directions to the front shaft body and the rear shaft body.

[0024] During specific implementation, since the two ends of one of the scraper shafts 702 are connected to the adjustment seat 704 for changing the rotation direction, the rotation direction of the front and rear sections of the scraper shaft 702 with the adjustment seat 704 is opposite to the rotation direction of the middle scraper paddle. At this time, when the middle parts of the two scraper shafts 702 rotate on the water surface, they will scrape the floating slag into the upper opening of the slag discharge channel 601, ensuring that small particles of debris floating on the water surface are discharged laterally along the slag discharge channel 601.

[0025] See also Figure 7-Figure 9 A cam groove 706 is formed on one side of the adjusting wheel 705. The cam groove 706 is composed of an arc portion concentric with the scraping shaft 702 and a protruding portion away from the arc portion. One end of the push-pull arm 707 is connected to a pin shaft 708 inserted into the cam groove 706. Racks are symmetrically arranged on the lower surface of the cross arm 709, and a toggle member 710 is movably connected to the side of the push-pull arm 707 close to the cross arm 709. The toggle member 710 includes a tooth column engaged with the rack and an L-shaped toggle rod fixed to the end of the tooth column. The copy plate 711 is fixed to the L-shaped toggle rod of the toggle member 710.

[0026] In specific implementation, when the adjusting wheel 705 pushes and pulls the pin 708 back and forth through the cam slot 706, the pin 708 drives the push-pull arm 707 to move back and forth along the cross arm 709. At this time, the push-pull arm 707 drives the tooth column of the toggle member 710 to engage with the rack on the bottom wall of the cross arm 709, thereby reciprocatingly driving the tooth column to rotate forward and reverse, ensuring that the tooth column can drive the L-shaped toggle lever of the toggle member 710 to rotate back and forth, and then the L-shaped toggle lever can drive the copy board 711 to rotate back and forth; When the two scraper shafts 702 rotate on the clamping seat 701, the adjusting wheels 705 on the two scraper shafts 702 will rotate in opposite directions. When the rotating adjusting wheels 705 are connected to the pin 708 of the push-pull arm 707 through the arc portion of the cam groove 706, the adjusting wheels 705 will not drive the push-pull arm 707 to move along the cross arm 709. At this time, the copying plate 711 on the toggle member 710 will remain suspended. When the pin 708 of the push-pull arm 707 moves from the arc portion of the cam groove 706 to the protruding portion When the push-pull arm 707 is at the farthest end of the protrusion of the cam groove 706, the adjusting wheel 705 will push the push-pull arm 707 to move toward the middle of the cross arm 709. At this time, the copying plate 711 on the toggle member 710 will be flipped from the suspended placement to the horizontal placement in the positive direction; when the pin shaft 708 of the push-pull arm 707 moves from the farthest end of the protrusion of the cam groove 706 to the arc part, the adjusting wheel 705 will pull the push-pull arm 707 to move toward the end of the cross arm 709. At this time, the copying plate 711 on the toggle member 710 will be flipped from the horizontal placement to the suspended placement in the reverse direction.

[0027] See also Figure 1-Figure 3 A slag discharge auger 501 is installed at one end of the water collecting bin 5 away from the material receiving trough 2. The middle part of the slag discharge auger 501 is connected to one end of the material selection trough 4. An inclined discharge port is provided on the upper side of the slag discharge auger 501.

[0028] In specific implementation, when the concrete waste blocks are sent to the interior of the slag discharge auger 501, the concrete waste blocks can be guided from the bottom to the discharge port through the slag discharge auger 501, and the slag washing water at the bottom of the slag discharge auger 501 can be filtered out by transporting the concrete waste blocks upward.

[0029] See also Figure 1-Figure 3 and Figure 10 An inclined draining platform 502 is provided above both sides of the water collecting bin 5 , and the draining platform 502 is located directly below the slag discharge channel 601 . A strip discharge port is provided on the surface of the water collecting bin 5 near the bottom end of the draining platform 502 .

[0030] In specific implementation, when the scraping shaft 702 guides the scum on the liquid surface downward along the scum discharge channel 601, the water will flow along the inclined draining platform 502 into the water collection bin 5, and the scum will be filtered on the draining platform 502. The impurities on the draining platform 502 can be discharged from the strip discharge port on one side of the water collection bin 5 by using a cleaning tool; In order to facilitate the discharge of sewage from the water collecting bin 5 and the slag discharge auger 501, a sewage valve can be set at the bottom of the water collecting bin 5 for regular sewage discharge. This is an existing technology and will not be elaborated here.

[0031] See also Figure 1 、 Figure 3 and Figure 10 A water pump 503 is installed on one side of the water collecting bin 5, and the water inlet end of the water pump 503 is inserted into the water collecting bin 5; the water outlet end of the water pump 503 is connected to a water supply pipe 504, and the upper end of the water supply pipe 504 is connected to the upper side wall of the scum cover 6 close to the material receiving trough 2.

[0032] During specific implementation, when the spiral shaft 201 rotates and stirs in the material receiving trough 2 and the material selection trough 4, the spiral shaft 201 transports the crushed waste slag along the material receiving trough 2 and the material selection trough 4 toward the slag discharge auger 501, and injects water into the material receiving trough 2, the material selection trough 4 and the slag discharge auger 501 so that the upper liquid surface just submerges the spiral shaft 201. When the rotating scraping shaft 702 discharges the slag on the upper layer of the liquid surface along the slag discharge channel 601 on both sides of the slag cover 6, the water flow for cleaning the waste slag will also be discharged. At this time, the water in the water collection bin 5 is extracted by the water pump 503 and returned to the material selection trough 4 along the water supply pipe 504, ensuring that the water flow in the material selection trough 4 can normally submerge the upper side of the spiral shaft 201.

[0033] See also Figure 1-Figure 3 A filter grid is provided inside the feed hopper 1 for blocking large-volume debris, and a strong magnet is fixed on the inner wall of one side of the feed hopper 1 to magnetically engage with the filter grid.

[0034] In specific implementation, when construction solid waste needs to be recycled, the construction solid waste is sent to the crushing equipment for crushing, so that the internal fillers in the construction solid waste are exposed. When the crushed construction solid waste is introduced into the feed hopper 1, the long steel bars and large-volume waste blocks can be filtered and intercepted through the filter grid, and the strong magnet and the filter grid can be used to magnetically attract the steel bars to prevent them from falling into the receiving trough 2.

[0035] See also Figure 1-Figure 4A base 3 is installed under the feed hopper 1, and the base 3 can support the feed hopper 1 on the top. A driving device 202 for driving the screw shaft 201 to rotate is provided between the base 3 and the feed hopper 1. The driving device 202 includes a motor installed under the base 3 and a synchronization component connecting the motor and the screw shaft 201. The synchronization component adopts a synchronization wheel and a synchronization belt drive or a chain and a sprocket drive; by starting the motor of the driving device 202, the synchronization component is driven to drive the screw shaft 201 to rotate in the receiving trough 2.

[0036] To sum up, the crushed construction solid waste is introduced into the receiving trough 2 along the feed hopper 1, and the synchronous component is driven by starting the motor of the driving device 202 to drive the screw shaft 201 to rotate in the receiving trough 2. The screw shaft 201 transports the crushed waste along the receiving trough 2 and the selection trough 4 to the slag discharge auger 501, and the debris floating on the water surface is removed from the slag cover 6 by the debris removal mechanism 7. When the concrete waste slag block is sent to the inside of the slag discharge auger 501, the concrete waste slag block can be guided from the bottom to the discharge port by the slag discharge auger 501, so that the equipment can use cleaning water to soak the crushed concrete blocks, and then use the cleaning water to efficiently remove the lightweight debris floating in the construction solid waste. The content not described in detail in this description belongs to the existing technology known to professional and technical personnel in this field.
