Description

Technical Field

[0001] This application relates to the field of waste recycling technology, and in particular to a construction waste recycling device. Background Technology

[0002] Recycling construction waste helps reduce resource waste, protect the environment, and promote sustainable development. When recycling metals for fertilizer, the metal parts of construction waste need to be separated from other non-metallic waste. The recycled metal waste can be transformed into raw materials through smelting or refining processes so that it can be used again to produce new metal products. The recycled metal can be used again to manufacture new building materials or other products, which helps reduce dependence on natural resources.

[0003] A search revealed Chinese Patent Publication No. CN218308219U, which discloses a construction waste recycling device. The device includes a movable base, a first drive motor, and a second drive motor. A handle is fixedly installed on one side of the movable base, and a recycling bin is fixedly installed above the movable base. A baffle plate is fixedly installed on one side of the inside of the recycling bin, and a discharge plate is fixedly installed on the side of the inside of the recycling bin away from the baffle plate. First cams are fixed to both ends of the output shaft of the crushing roller. A slot is formed on the surface of the recycling bin below the slot, and a movable mounting plate is slidably connected to the slot. This construction waste recycling device, through the use of the second drive motor and the second cams, facilitates the movement of the discharge plate and the electromagnet discharge plate up and down inside the recycling bin under the action of a second spring. This not only effectively avoids the blockage of construction waste caused by concentrated dumping but also improves the discharge efficiency of the electromagnet discharge plate.

[0004] Regarding the aforementioned related technologies, the inventors have discovered the following drawbacks:

[0005] In this patent, the feeding tray is made of electromagnet to adsorb magnetic materials. However, when the adsorption is saturated, the electromagnet on the feeding tray needs to be de-energized after the cement material flows out before the material can be discharged. This reduces the recycling efficiency. Furthermore, if the material accumulates too thickly during the falling process, some fine and upper magnetic materials may flow out with the feeding tray, resulting in incomplete screening during the recycling process and the loss of some recyclable materials.

[0006] Therefore, in response to the above problems, the applicant provides a construction waste recycling device. Utility Model Content

[0007] In order to solve the problems mentioned in the background art, this application provides a construction waste recycling device.

[0008] This application provides a construction waste recycling device, which adopts the following technical solution:

[0009] A construction waste recycling device includes a second support and a fixed slider. The second support is equipped with an adsorption mechanism for rotating and adsorbing steel bars. The adsorption mechanism includes a first rotating shaft and a second rotating shaft. Electromagnetic column one and electromagnet column two are respectively fixedly connected to the outer circumference of the first rotating shaft and the second rotating shaft. The rotating end of the first rotating shaft is fixedly connected to the rotating end of the second motor.

[0010] The fixed slider is equipped with a discharge mechanism to facilitate the discharge of steel bars. The discharge mechanism includes a multi-stage electric push rod. The output end of the multi-stage electric push rod is fixedly connected to a "U"-shaped frame. Both ends of the "U"-shaped frame are fixedly connected to steel bar discharge trays.

[0011] Optionally, it also includes a feeding box, with support legs fixedly connected to the four corners of the bottom of the feeding box, a placement platform fixedly connected to one side of the support legs, and a spring fixedly connected to the bottom surface of the placement platform, with the top of the spring contacting the bottom surface of the unloading tray.

[0012] Optionally, a bracket is fixedly connected to both sides of the placement platform, a base of a motor is fixedly connected to one side of the bracket, a fixed shaft is fixedly connected to the rotating end of the motor, and cams are fixedly connected to both ends of the fixed shaft. The outer circumferential wall of the cam contacts the bottom surface of the feed tray.

[0013] Optionally, horizontal support rods are fixedly connected to both ends of one side of the placement platform, and the two horizontal support rods are rotatably connected to both sides of the feeding tray.

[0014] Optionally, brackets 2 are fixedly connected to the outer walls on both sides of the feeding tray. The two ends of rotating shaft 1 and rotating shaft 2 are rotatably connected to the corresponding two brackets 2, and the base of motor 2 is fixedly connected to one of the brackets 2.

[0015] Optionally, a driving gear and a driven gear are fixedly connected to one end of the first rotating shaft and the second rotating shaft, respectively, with the driving gear meshing with the driven gear.

[0016] Optionally, the outer circumference of the rotating shaft one and the rotating shaft two are respectively fixedly connected in a ring array with multiple rows of electromagnet columns one and multiple rows of electromagnet columns two. One end of each electromagnet column one and electromagnet column two is close to the bottom inner wall of the feeding tray. There is an electromagnet column one between each row of two adjacent electromagnet columns two. The vertical orthographic projection of each electromagnet column one and electromagnet column two is a triangular structure.

[0017] Optionally, four fixed sliders are fixedly connected to one side of the feeding tray. Two adjacent fixed sliders are slidably connected to the grooves on both sides of the rebar feeding tray. The two rebar feeding trays are located below the rotating shaft one and rotating shaft two, respectively. The base of the multi-stage electric push rod is fixedly connected to one of the brackets two. The fixed sliders, rebar feeding trays and multi-stage electric push rods are all inclined to make the material fall better.

[0018] In summary, this application includes the following beneficial technical effects:

[0019] 1. In this utility model, the motor drives each row of electromagnet columns one and two to approach the top of the feeding tray and then stops. The magnetic material in the material will be attracted by the electromagnet columns one and two vertically set above the feeding tray, which can avoid the accumulation of too much material, which would cause the upper layer or small magnetic material to flow out with the feeding tray, thus resulting in the waste of magnetic material.

[0020] 2. This utility model uses a second motor to drive two electromagnet columns containing magnetic materials to rotate. The controller controls the de-energization of the first and second electromagnet columns, which allows the magnetic materials in the saturated electromagnet columns to fall into the steel bar discharge tray and flow out quickly, thus separating the magnetic materials from the raw materials and accelerating the screening efficiency in the waste recycling process.

Detailed Implementation

[0027] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0028] This application discloses a construction waste recycling device.

[0029] like Figure 1-5 As shown, a construction waste recycling device includes a support frame 4 and a fixed slider 12. The support frame 4 is equipped with an adsorption mechanism for rotating and adsorbing steel bars. The adsorption mechanism includes a rotating shaft 6 and a rotating shaft 10. Electromagnetic columns 7 and 11 are respectively fixedly connected to the outer circumference of the rotating shaft 6 and the rotating shaft 10. The rotating end of the rotating shaft 6 is fixedly connected to the rotating end of the motor 5.

[0030] The fixed slider 12 is provided with a discharge mechanism to facilitate the discharge of steel bars. The discharge mechanism includes a multi-stage electric push rod 15. The output end of the multi-stage electric push rod 15 is fixedly connected to a "U"-shaped frame 14. Both ends of the "U"-shaped frame 14 are fixedly connected to steel bar discharge trays 13.

[0031] Please see Figure 1 and Figure 3 This also includes a feeding box 100, with four support legs fixedly connected to the bottom corners of the feeding box 100. A placement platform 101 is fixedly connected to one side of each support leg. A spring 105 is fixedly connected to the bottom surface of the placement platform 101, with the top of the spring 105 contacting the bottom surface of the unloading tray 3. Support brackets 102 are fixedly connected to both sides of the placement platform 101. A base of a motor 103 is fixedly connected to one side of each support bracket 102. A fixed shaft is fixedly connected to the rotating end of the motor 103, and cams 104 are fixedly connected to both ends of the fixed shaft. The outer circumference of the cam 104 contacts the bottom surface of the unloading tray 3. The placement platform 101... Both ends of one side are fixedly connected to horizontal support rods 2. The two horizontal support rods 2 are rotatably connected to both sides of the feeding tray 3. The motor 103 is externally powered and its stroke is controlled by a controller. When the feeding box 100 is filled with recycled material, the motor 103 is manually controlled by the controller. The motor 103 drives the fixed shaft and cam 104 to rotate. The rotation of cam 104 will cause the feeding tray 3 to vibrate up and down. The spring 105 plays a role in buffering the vibration of the feeding tray 3. As the cam 104 drives the feeding tray 3 to vibrate, the material falls. The feeding tray 3 is tilted to allow the material to fall more effectively.

[0032] Please see Figure 4The outer walls on both sides of the feeding tray 3 are fixedly connected to brackets 2 4. The two ends of the rotating shaft 1 6 and rotating shaft 2 10 are rotatably connected to the corresponding two brackets 2 4. The base of motor 2 5 is fixedly connected to one of the brackets 2 4. The motor 2 5 is externally powered and its stroke is controlled by a controller.

[0033] Please see Figure 4 A drive gear 8 and a driven gear 9 are fixedly connected to one end of the first rotating shaft 6 and the second rotating shaft 10, respectively. The drive gear 8 meshes with the driven gear 9. The second motor 5 drives the first rotating shaft 6 and the drive gear 8 to rotate. The drive gear 8 meshes with the driven gear 9 and drives the second rotating shaft 10 to rotate.

[0034] Please see Figure 4 The outer circumference of the rotating shaft 16 and rotating shaft 210 are respectively fixedly connected in a ring array to multiple rows of electromagnet columns 17 and multiple rows of electromagnet columns 21. One end of each electromagnet column 17 and electromagnet column 21 is close to the bottom inner wall of the feeding tray 3. There is an electromagnet column 17 interspersed between two adjacent electromagnet columns 21 in each row. The vertical projection of each electromagnet column 17 and electromagnet column 21 is a triangular structure. Both electromagnet columns 17 and electromagnet columns 21 are externally powered. Each row of electromagnet columns 17 and each row of electromagnet columns 21 is controlled by a controller to synchronously turn on and off. The triangular structure of the electromagnet columns 17 and electromagnet columns 21 is mainly to facilitate the material to first pass through the convergence point of the two side lines and then slowly diffuse to both sides, thereby limiting its falling speed and increasing the adsorption effect.

[0035] Please see Figure 4 and Figure 5 Four fixed sliders 12 are fixedly connected to one side of the feeding tray 3. Two adjacent fixed sliders 12 are slidably connected to the grooves 130 on both sides of the rebar feeding tray 13. The two rebar feeding trays 13 are located below the rotating shaft 6 and the rotating shaft 10, respectively. The base of the multi-stage electric push rod 15 is fixedly connected to one of the brackets 4. The fixed sliders 12, the rebar feeding tray 13 and the multi-stage electric push rod 15 are all inclined to make the material fall better.

[0036] The implementation principle of a construction waste recycling device according to an embodiment of this application is as follows:

[0037] When materials are ready to be fed from the feed hopper 100, the controller manually starts the motor 25. The motor 25 drives the rotating shaft 16 and the drive gear 8 to rotate. The drive gear 8 meshes with the driven gear 9 to rotate the rotating shaft 20. The motor 25 drives each row of electromagnet columns 17 and 21 to approach the top of the feed tray 3 and then stops. The controller controls the electromagnet columns 17 and 211 to be energized. At this time, the position of the steel bar discharge tray 13 is pre-positioned by the multi-stage electric push rod 15 to the pushed-out state as shown in the attached diagram of the instruction manual. Figure 5 The state shown.

[0038] After the material enters the feed box 100, the material falls into the feed tray 3 and slides from the high point to the low point as the feed tray 3 is tilted. The magnetic material in the material flowing through the electromagnet column 7 and the electromagnet column 11 will be attracted by the electromagnet column 7 and the electromagnet column 11 above the feed tray 3.

[0039] The controller controls motor 25 to turn on after a certain period of time and drive electromagnet column 17 and electromagnet column 211 to rotate 90 degrees. When electromagnet column 17 and electromagnet column 211, which first adsorb the magnetic material, rotate 270 degrees, the controller controls the output end of the multi-stage electric push rod 15 to enter the input end. The retraction of the multi-stage electric push rod 15 will drive the "U"-shaped frame 14 and the rebar discharge tray 13 to retract. At the same time, the rebar discharge tray 13 will tilt and slide in the fixed slider 12. Finally, the rebar discharge tray 13 will be located in the electromagnet column 17 and electromagnet column 21 containing the magnetic material. The controller controls the electromagnet column 17 and electromagnet column 21 to de-energize again. At this time, the magnetic material will fall from the electromagnet column 17 and electromagnet column 21 and flow out with the tilting setting of the rebar discharge tray 13.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
