Description

Technical Field

[0001] This utility model relates to the field of construction solid waste treatment technology, specifically to an environmentally friendly commercial concrete waste recycling and reuse equipment. Background Technology

[0002] Commercial concrete, short for ready-mixed concrete, refers to concrete that is pre-mixed at a batching plant and sold as a commodity after being made from cement, aggregates, water, and other materials in a specific ratio. The production of commercial concrete generates a large amount of waste residue containing cement slurry. Traditional landfill disposal methods have several shortcomings: firstly, the high water content of the waste residue can lead to soil pollution due to the alkaline wastewater, which is detrimental to environmental protection; secondly, while direct landfilling is convenient, it wastes resources and prevents the recycling and reuse of the waste residue. To address these issues, the inventor proposes an environmentally friendly commercial concrete waste residue recycling and reuse device. Utility Model Content

[0003] To address the issues of land pollution and resource waste that may result from the current treatment of commercial concrete waste, the purpose of this invention is to provide an environmentally friendly commercial concrete waste recycling and reuse device.

[0004] To solve the above technical problems, this utility model adopts the following technical solution: an environmentally friendly commercial concrete waste recycling and reuse equipment, including a crushing box, an inclined platform fixedly connected to the inner bottom wall of the crushing box, a shell fixedly connected to the outer side wall of the crushing box, a motor installed inside the shell, a first crushing roller fixedly connected to the output shaft end of the motor, a first gear fixedly sleeved on the output shaft of the motor, a second gear meshing with the side wall of the first gear, a horizontal shaft fixedly connected through the middle of the side wall of the second gear, a second crushing roller fixedly connected to the side wall of the horizontal shaft, the first crushing roller and the second crushing roller corresponding to each other and rotating in opposite directions, a guide plate rotatably provided inside the crushing box and below the first crushing roller and the second crushing roller, a water leakage hole penetrating through the side wall of the guide plate, a water storage tank provided below the crushing box, a discharge port penetrating through the lower part of the side wall of the crushing box, the guide plate located inside the discharge port, a feeding platform provided on one side of the discharge port, and a semi-magnetic roller provided at the output end of the feeding platform.

[0005] Preferably, the side wall of the housing is provided with heat dissipation holes, which correspond to the motor. A dustproof mesh is fixedly connected to the port of each heat dissipation hole. A base is provided on the side wall of the motor, and the base is fixedly connected to the inner wall of the housing. The heat dissipation holes allow air to circulate between the inside and outside of the housing to dissipate heat from the motor. The dustproof mesh prevents external dust from entering the housing through the heat dissipation holes. The motor is mounted on the base. Starting the motor causes the first crushing roller and the first gear to rotate. Through the meshing of the first and second gears, the horizontal shaft rotates, which in turn causes the second crushing roller to rotate. The waste residue is crushed by the first and second crushing rollers rotating in opposite directions. The bottom of the box is fixedly connected to the support legs. The side wall of the water storage tank is fixedly connected to the side wall of the support legs. A drain pipe is inserted and fixedly connected to the lower part of the side wall of the water storage tank. A flow valve is provided on the side wall of the drain pipe. The crushing box is hollow. The opening of the water storage tank corresponds to the bottom port of the crushing box. The support legs are used to support the crushing box. When the commercial concrete waste is poured into the crushing box, the wastewater in the waste can fall into the water storage tank through the drain hole. When the waste is squeezed and crushed by the first crushing roller and the second crushing roller, the waste can be further dehydrated. The dehydrated liquid can be collected and stored in the water storage tank through the drain hole on the guide plate, so as to be discharged externally through the drain pipe, avoiding the direct discharge of wastewater and pollution of the environment.

[0006] Preferably, an electric cylinder is hinged to the inner bottom wall of the crushing box. The electric cylinder includes a telescopic rod, the end of which is hinged to the bottom surface of the guide plate, as shown in Figures 1 and 2. A drainage hole is provided on the guide plate at a position corresponding to the electric cylinder to reduce damage to the electric cylinder when draining water through the hole. When in use, the electric cylinder must be a dustproof and waterproof model. When the electric cylinder is activated, a convex shaft is inserted into the outer wall of the guide plate under the action of the telescopic rod. The convex shaft is rotatably connected to the crushing box, allowing the guide plate to rotate and increase its inclination, so that the crushed material falls from the discharge port. The material is fed onto the unloading platform, where it undergoes magnetic separation to remove iron and other metallic impurities such as reinforcing bars through a semi-magnetic drum. A support is rotatably connected to the side wall of the semi-magnetic drum. An aggregate receiving box is located on one side of the support, and a metal receiving box is located on the other side. The semi-magnetic drum includes a semi-magnetic ring. When metallic impurities and aggregates pass through the semi-magnetic drum, the metallic impurities are attracted to it, while the aggregates fall into the aggregate receiving box for centralized processing. The metallic impurities attracted by the semi-magnetic drum are no longer attracted when they move to the non-magnetic zone and fall into the metal receiving box for centralized processing.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows: it can realize continuous operation of crushing, dewatering and magnetic separation of commercial concrete waste residue, thereby enabling the recycling and reuse of commercial concrete waste residue, improving environmental protection, avoiding the impact of metal impurities on the quality of recycled aggregate, avoiding the waste of resources caused by direct landfilling of commercial concrete waste residue in the traditional way, and also avoiding the land pollution caused by direct landfilling or discharge of alkaline wastewater contained in the waste residue.

[0015] Example: Figures 1-4As shown, this utility model provides an environmentally friendly commercial concrete waste recycling and reuse equipment, including a crushing box 1. An inclined platform 3 is fixedly connected to the inner bottom wall of the crushing box 1. A shell 4 is fixedly connected to the outer side wall of the crushing box 1. A motor 5 is installed inside the shell 4. A first crushing roller 7 is fixedly connected to the output shaft end of the motor 5. A first gear 8 is fixedly sleeved on the output shaft of the motor 5. A second gear 9 meshes with the side wall of the first gear 8. A horizontal shaft 10 is inserted and fixedly connected to the middle of the side wall of the second gear 9. The side wall of the horizontal shaft 10 is fixedly connected to... There is a second crushing roller 11, and the first crushing roller 7 corresponds to the second crushing roller 11 and rotates in the opposite direction. Inside the crushing box 1, below the first crushing roller 7 and the second crushing roller 11, there is a guide plate 12. The side wall of the guide plate 12 is provided with a water leakage hole 13. A water storage tank 16 is provided below the crushing box 1. A discharge port is provided through the lower part of the side wall of the crushing box 1. The guide plate 12 is located inside the discharge port. A discharge platform 18 is provided on one side of the discharge port. A semi-magnetic roller 19 is provided at the output end of the discharge platform 18.

[0016] A heat dissipation hole 23 is provided through the side wall of the housing 4. The heat dissipation hole 23 corresponds to the motor 5. A dustproof net is fixedly connected to the port of the heat dissipation hole 23. A base 6 is provided on the side wall of the motor 5. The base 6 is fixedly connected to the inner wall of the housing 4.

[0017] By adopting the above technical solution, the heat dissipation hole 23 is used to allow air to circulate inside and outside the housing 4 to dissipate heat from the motor 5. The dustproof net is used to prevent external dust from entering the housing 4 through the heat dissipation hole 23. The motor 5 is installed through the base 6. Starting the motor 5 can make the first crushing roller 7 and the first gear 8 rotate. Through the meshing of the first gear 8 and the second gear 9, the horizontal shaft 10 can rotate, which in turn can make the second crushing roller 11 rotate. The waste residue can be crushed by the first crushing roller 7 and the second crushing roller 11 rotating in opposite directions.

[0018] The bottom surface of the crushing box 1 is fixedly connected to the support leg 2. The side wall of the water storage tank 16 is fixedly connected to the side wall of the support leg 2. The lower part of the side wall of the water storage tank 16 is fixedly connected to the drain pipe 17. The side wall of the drain pipe 17 is equipped with a flow valve. The crushing box 1 is hollow. The opening of the water storage tank 16 corresponds to the bottom port of the crushing box 1.

[0019] By adopting the above technical solution, the support leg 2 is used to support the crushing box 1. When the commercial concrete waste is poured into the crushing box 1, the wastewater in the waste can fall into the water storage tank 16 through the water leakage hole 13. When the waste is squeezed and crushed by the first crushing roller 7 and the second crushing roller 11, the waste can be further dehydrated. The dehydrated liquid can be collected and stored in the water storage tank 16 through the water leakage hole 13 on the guide plate 12, so as to be discharged externally through the drain pipe 17, thus avoiding the direct discharge of wastewater and pollution of the environment.

[0020] An electric cylinder 14 is hinged to the inner bottom wall of the crushing box 1. The electric cylinder 14 includes a telescopic rod 15, and the end of the telescopic rod 15 is hinged to the bottom surface of the guide plate 12.

[0021] By adopting the above technical solutions, such as Figure 2 as well as Figure 3 As shown, a drainage hole 13 is provided on the guide plate 12 at the position corresponding to the electric cylinder 14 to reduce damage to the electric cylinder 14 when draining water through the drainage hole 13. Furthermore, when using the electric cylinder 14, a dustproof and waterproof model must be selected. When the electric cylinder 14 is started, under the action of the telescopic rod 15, and as... Figure 1 As shown, a convex shaft is inserted into the outer wall of the guide plate 12. The convex shaft is rotatably connected to the crushing box 1, so that the guide plate 12 can rotate to increase the inclination of the guide plate 12, so that the crushed material falls from the discharge port onto the unloading platform 18, and then the crushed material is magnetically separated by the semi-magnetic drum 19 to remove iron and remove metal impurities such as steel bars.

[0022] A bracket 20 is rotatably connected to the side wall of the semi-magnetic roller 19. An aggregate receiving box 21 is provided on one side of the bracket 20, and a metal receiving box 22 is provided on the other side of the bracket 20.

[0023] By adopting the above technical solution, the semi-magnetic roller 19 includes a semi-magnetic ring 24. When metal impurities and aggregates pass through the semi-magnetic roller 19, the metal impurities are attracted by the semi-magnetic roller 19, while the aggregates fall into the aggregate receiving box 21 for centralized processing. Figure 4 As shown, the metal impurities adsorbed by the semi-magnetic roller 19 will no longer be adsorbed when they move to the non-magnetic area with the semi-magnetic roller 19, and will fall into the metal receiving box 22 for centralized processing.

[0024] Working principle: When using this utility model, the waste residue is placed in the crushing box 1. The wastewater in the waste residue can fall into the water storage tank 16 through the water leakage hole 13. At the same time, starting the motor 5 can make the first crushing roller 7 and the first gear 8 rotate. Through the meshing of the first gear 8 and the second gear 9, the horizontal shaft 10 can be rotated, which in turn can make the second crushing roller 11 rotate. The waste residue can be crushed by the first crushing roller 7 and the second crushing roller 11 rotating in opposite directions.

[0025] When the waste residue is squeezed and crushed by the first crushing roller 7 and the second crushing roller 11, the waste residue can be further dewatered. The dewatered liquid can be collected in the water storage tank 16 through the water leakage hole 13 on the guide plate 12, and then discharged through the drain pipe 17 for centralized external treatment, thus avoiding direct discharge of wastewater and pollution of the environment.

[0026] Next, the electric cylinder 14 is activated, and under the action of the telescopic rod 15, and as... Figure 1 As shown, a convex shaft is inserted into the outer wall of the guide plate 12. The convex shaft is rotatably connected to the crushing box 1, allowing the guide plate 12 to rotate and increase its inclination. This allows the crushed material to fall from the discharge port onto the unloading platform 18. When metal impurities and aggregates pass through the semi-magnetic drum 19, the metal impurities are attracted by the semi-magnetic drum 19, while the aggregates fall through the semi-magnetic drum 19 into the aggregate receiving box 21 for centralized processing. Figure 4 As shown, the metal impurities adsorbed by the semi-magnetic drum 19 will no longer be adsorbed when they move to the non-magnetic zone with the semi-magnetic drum 19, and will fall into the metal receiving box 22 for centralized processing, so as to complete the magnetic separation and iron removal of the crushed material and remove metal impurities such as steel bars.

[0027] All standard parts used in this invention can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0028] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
