Description

Technical Field

[0001] This invention relates to the field of solid waste treatment technology, and in particular to a device and method for treating construction solid waste. Background Technology

[0002] With the acceleration of urbanization, the construction industry has ushered in unprecedented development. However, the large amount of construction waste generated in this process will impose a serious burden on the environment if it is not properly handled.

[0003] When processing concrete, jaw crushers are usually used to break it up and separate it from the reinforcing steel. However, due to the limited crushing range of jaw crushers, some concrete will still remain on the reinforcing steel after crushing. Further processing of the concrete on the reinforcing steel is required. The uneven distribution of the concrete residue on the reinforcing steel makes the subsequent cleaning steps cumbersome and inefficient. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a device and method for treating construction solid waste.

[0005] The technical implementation of the present invention is as follows: a construction solid waste treatment device includes a frame and a cleaning mechanism disposed on the frame. The cleaning mechanism includes a feed plate and a lower file plate fixedly connected to the frame. The feed plate and the lower file plate are connected. A swing frame is hinged inside the frame and located above the lower file plate. An upper file plate is slidably mounted on the swing frame. A compression spring is provided between the upper file plate and the swing frame. A drive mechanism for controlling the sliding of the upper file plate is provided on the frame. A limiting mechanism for limiting the upper file plate is provided on the swing frame.

[0006] In a preferred embodiment of the present invention, the driving mechanism includes hydraulic cylinders symmetrically mounted on the frame, a connecting plate fixedly connected to the telescopic end of the hydraulic cylinder, a driving plate hinged to the connecting plate, and driving rods symmetrically fixedly connected to the swing frame to cooperate with the driving plate.

[0007] In a preferred embodiment of the present invention, the driving mechanism further includes a support rod fixedly connected to the connecting plate, and a first convex shaft cooperating with the support rod is fixedly connected to the driving plate.

[0008] In a preferred embodiment of the present invention, the driving mechanism further includes an inclined plate symmetrically fixed to the frame, and a second convex shaft that cooperates with the inclined plate is symmetrically fixed to the upper file plate.

[0009] In a preferred embodiment of the present invention, the upper file plate is provided with a through groove, the limiting mechanism includes an I-beam frame slidably connected in the through groove, a tension spring is provided between the I-beam frame and the through groove, pins are symmetrically fixed on the I-beam frame, and pin holes matching the pins are symmetrically opened on the swing frame.

[0010] In a preferred embodiment of the present invention, the limiting mechanism further includes a telescopic rod symmetrically fixed to the swing frame, a tension spring is provided between the telescopic end and the fixed end of the telescopic rod, a third convex shaft is fixedly connected to the telescopic end of the telescopic rod, a limiting frame is symmetrically fixed inside the frame, and a blocking block that cooperates with the third convex shaft is elastically slidably connected inside the limiting frame.

[0011] In a preferred embodiment of the present invention, a support frame that cooperates with the I-beam is symmetrically fixed to the frame.

[0012] In a preferred embodiment of the present invention, guide rails are symmetrically fixed to the frame, and fourth convex shafts that move within the guide rails are symmetrically fixed to the upper file plate.

[0013] In a preferred embodiment of the present invention, a plurality of breaking needles are slidably connected through the upper file plate, and a return spring is provided between the plurality of breaking needles and the upper file plate.

[0014] In a preferred embodiment of the present invention, a method for treating construction solid waste using a waste treatment device includes the following steps: S1: Control the extension end of the hydraulic cylinder to extend, so that the drive plate presses against the drive rod. The drive rod drives the swing frame to rotate, and the swing frame drives the upper file plate to move until the drive plate disengages from the drive rod, so that the upper file plate hits the steel bar to achieve the initial removal of concrete. S2: The upper file plate is limited by the pin. When the swing frame rotates and resets, the pin is disengaged from the pin hole of the swing frame by the cooperation of the I-beam frame and the support frame, so that the upper file plate and the lower file plate cooperate to remove the concrete on the steel bar. S3: Through the cooperation between the third convex shaft and the blocking block, and the cooperation between the guide rail and the fourth convex shaft, the sliding trajectory of the upper file plate is restricted when the compression spring is released, thus ensuring the effective removal of concrete.

[0015] Compared with the prior art, the present invention has the following advantages: 1. This invention, by setting up a cleaning mechanism, when cleaning steel bars with residual concrete, controls the extension of the hydraulic cylinder to extend the swing frame, which drives the upper file plate to move. Then, the swing frame, under the influence of the weight of the upper file plate, quickly rotates downward and smashes onto the steel bar, which can initially remove the residual concrete from the steel bar. By setting up a driving mechanism, the upper file plate can slide along the swing frame, so that the upper file plate, together with the lower file plate, can further remove the residual concrete from the steel bar, ensuring the cleaning effect of residual concrete.

[0016] 2. By setting up an I-beam frame and a pin, when the swing frame rotates and resets, the support frame provides support for the I-beam frame, which enables the pin to disengage from the pin hole of the swing frame, thus automatically releasing the limit on the upper file plate.

[0017] 3. By setting a third convex shaft and a blocking block, when the swing frame rotates and resets, the blocking block can limit the swing frame through the third convex shaft and the telescopic rod, thereby limiting the sliding trajectory of the upper file plate and ensuring the file removal effect on concrete.

[0020] Although the invention may be described with respect to specific applications or industries, those skilled in the art will recognize its broader applicability. Those skilled in the art will understand that terms such as "above," "below," "upward," "downward," etc., are used to describe the drawings and not to indicate a limitation on the scope of the invention as defined by the appended claims. Any numerical designations such as "first" or "second" are merely illustrative and not intended to limit the scope of the invention in any way.

[0021] Example 1 A type of equipment for treating construction solid waste, such as Figure 1 and Figure 2 As shown, the device includes a frame 1 and a cleaning mechanism mounted on the frame 1. The cleaning mechanism includes a feed plate 201 and a lower file plate 202 fixedly connected to the frame 1. The feed plate 201 is fixedly connected to the left side of the lower file plate 202. A swing frame 203 located above the lower file plate 202 is hinged inside the frame 1. An upper file plate 204 is slidably mounted on the swing frame 203. A compression spring is provided between the left side of the upper file plate 204 and the outer wall of the swing frame 203. A drive mechanism is provided on the frame 1 to control the upper file plate 204 to slide along the swing frame 203. A limiting mechanism is provided on the swing frame 203 to limit the upper file plate 204.

[0022] like Figure 1 and Figure 3 As shown, the drive mechanism includes hydraulic cylinders 301 symmetrically mounted on the frame 1. A connecting plate 302 is fixedly connected to the telescopic end of the hydraulic cylinders 301. A drive plate 303 is hinged to the right side of the connecting plate 302. A drive rod 304 that cooperates with the drive plate 303 is symmetrically fixedly connected to the swing frame 203.

[0023] like Figure 3 As shown, the drive mechanism also includes two support rods 401 fixed to the opposite sides of the two connecting plates 302, and a first convex shaft 402 that cooperates with the support rods 401 is fixed to the opposite sides of the two drive plates 303.

[0024] like Figure 4As shown, the drive mechanism also includes a slant plate 501 symmetrically fixed to the frame 1, and a second convex shaft 502 that cooperates with the slant plate 501 is symmetrically fixed to the left side of the upper file plate 204.

[0025] like Figures 4-6 As shown, the upper file plate 204 has a through groove, and the limiting mechanism includes an I-beam frame 601 that is slidably connected in the through groove. A tension spring is provided between the bottom of the I-beam frame 601 and the bottom of the inner wall of the through groove. Pins 602 are symmetrically fixed on the I-beam frame 601, and pin holes matching the pins 602 are symmetrically opened on the outer wall of the swing frame 203.

[0026] like Figure 7 and Figure 8 As shown, the limiting mechanism also includes telescopic rods 701 that are symmetrically fixed to the bottom of the outer wall of the swing frame 203. A tension spring is provided between the telescopic end and the fixed end of the telescopic rod 701. A third convex shaft 702 is fixed to the near side of the telescopic ends of the two telescopic rods 701. A limiting frame 703 is symmetrically fixed to the frame 1. A blocking block 704 that cooperates with the third convex shaft 702 is elastically slidably connected in the horizontal direction inside the limiting frame 703.

[0027] like Figure 7 As shown, a support frame 801 that cooperates with the I-beam 601 is symmetrically fixed on the frame 1. When the I-beam 601 contacts the support frame 801, the pin 602 can disengage from the pin hole of the swing frame 203.

[0028] like Figure 9 As shown, the top of the frame 1 is symmetrically fixed with guide rails 901, and the outer wall of the upper file plate 204 is symmetrically fixed with a fourth cam shaft 902 that moves within the guide rails 901.

[0029] like Figure 10 As shown, a number of breaking needles 1001 are slidably connected through the upper file plate 204. Each of the breaking needles 1001 and the upper file plate 204 is provided with a return spring. The breaking needles 1001 are used to further clean the concrete attached to the reinforcing bars.

[0030] Initially, the compression spring is in the released state, the I-beam 601 abuts against the tops of the two support frames 801, the two pins 602 abut against the outer wall of the swing frame 203, and the tension spring is in the extended state. First, the telescopic end of the hydraulic cylinder 301 is controlled to reciprocate. When the telescopic end of the hydraulic cylinder 301 extends, it drives the drive plate 303 to rise via the connecting plate 302. Subsequently, the two drive plates 303 contact and press against their corresponding drive rods 304. The support rod 401 provides support for the drive plate 303 via the first convex shaft 402. The two drive rods 304, under force, drive the swing frame 203 to rotate upwards. As the swing frame 203 rotates upward, the drive rod 304 gradually slides to the right along the top of the corresponding drive plate 303. The swing frame 203 drives the upper file plate 204 to move upward, and the upper file plate 204 drives the I-beam frame 601 to move upward, moving the I-beam frame 601 away from the two support frames 801. At this time, the steel bars with residual concrete are placed on the unloading plate 201. Under the action of their own weight, the steel bars slide down the unloading plate 201 onto the lower file plate 202. At the same time, the two second convex shafts 502 are squeezed by the two inclined plates 501 respectively. The two second convex shafts 502 drive the upper file plate 204 to slide along the swing frame 203, and the compression spring contracts under force. The two pins 602 align with the two pin holes of the swing frame 203. The tension spring contracts, causing the I-beam 601 to slide. The I-beam 601 drives the two pins 602 to insert into the two pin holes of the swing frame 203, limiting the upper file plate 204. The compression spring remains contracted. At the same time, the drive rod 304 passes over the corresponding drive plate 303. The swing frame 203 rotates rapidly downwards due to the weight of the upper file plate 204. The upper file plate 204 drives the two second convex shafts 502 to move. A gap is created between the second convex shafts 502 and the corresponding inclined plates 501. Subsequently, the I-beam 601 contacts the support frame 801. The support frame 801 is the I-beam 602. 1. Provide support, the swing frame 203 continues to rotate downwards, causing the I-beam 601 to slide along the through groove of the upper file plate 204. The tension spring is stretched under force, and the I-beam 601 drives the pin 602 to slide along the pin hole of the swing frame 203. The upper file plate 204 strikes the steel bar, and the residual concrete on the steel bar is initially removed until the swing frame 203 rotates back to its original position. At this time, the pin 602 disengages from the pin hole, allowing the upper file plate 204 to move. The compression spring is released, causing the upper file plate 204 to slide. The upper file plate 204 and the lower file plate 202 cooperate to remove the residual concrete on the steel bar, further causing the concrete to fall off, until the upper file plate 204 slides back to its original position.

[0031] When the telescopic end of the hydraulic cylinder 301 retracts, the telescopic end of the hydraulic cylinder 301 drives the drive plate 303 to descend through the connecting plate 302. Then, the drive plate 303 contacts the corresponding drive rod 304, and the drive plate 303 continues to descend. The drive plate 303 is squeezed upward by the drive rod 304 and rotates until the telescopic end of the hydraulic cylinder 301 retracts and resets, and the drive plate 303 disengages from the drive rod 304 and rotates to reset.

[0032] Initially, the third cam 702 is located above the adjacent limit frame 703, and the fourth cam 902 is located at the right end of the adjacent guide rail 901. When the swing frame 203 rotates upward, driving the upper file plate 204 to move, the rotation speed of the swing frame 203 is relatively slow. The swing frame 203 drives the two telescopic rods 701 to move. Because the upward rotation speed of the swing frame 203 is relatively slow, the tension spring remains in a contracted state, keeping the telescopic ends of the two telescopic rods 701 in a contracted state. The telescopic ends of the telescopic rods 701 drive the third cam 702 to move, and the upper file plate 204... 04 drives the two fourth cam shafts 902 to disengage from the two guide rails 901 respectively. When the swing frame 203 rotates downward and drives the upper file plate 204 to move, due to the high speed of the swing frame 203, the telescopic ends of the two telescopic rods 701 extend under the influence of centrifugal force, and the tension springs extend under force. The telescopic ends of the telescopic rods 701 drive the third cam shaft 702 on them to move. Subsequently, the third cam shaft 702 contacts and presses against the adjacent blocking block 704. The blocking block 704 is elastically contracted and slides under force until the swing frame 203 rotates back to its original position. At this time, the blocking block 704... 4. The compression elasticity of the third convex shaft 702 is released, and the sliding reset occurs, with the upper file plate 204 fitting against the outer wall of the third convex shaft 702. The blocking block 704 limits the swing frame 203 through the third convex shaft 702 and the telescopic rod 701, thereby preventing the swing frame 203 from rotating upward when the upper file plate 204 falls on the steel bar. At the same time, the fourth convex shaft 902 is engaged with the left end of the adjacent guide rail 901. When the compression spring is released, causing the upper file plate 204 to slide, the upper file plate 204 causes the two fourth convex shafts 902 to slide along the two guide rails 901 respectively. 01 The sliding trajectory of the swing frame 203 is further limited by the fourth cam shaft 902, thereby ensuring the scraping effect of the upper file plate 204 and the lower file plate 202 on the residual concrete and preventing the upper file plate 204 from being pushed up by the steel bars and concrete. Before the hydraulic cylinder 301 extends again, the tension spring contracts and drives the telescopic end of the telescopic rod 701 to retract and reset. The telescopic end of the telescopic rod 701 drives the third cam shaft 702 to slide away from the limiting frame 703. At this time, the upper file plate 204 has slid and reset, thereby ensuring that the swing frame 203 can rotate smoothly in the future.

[0033] As a further supplement, when the swing frame 203 drives the upper file plate 204 to move, the upper file plate 204 drives several breaking needles 1001 to move. When the swing frame 203 rotates and resets, the several breaking needles 1001 slide downward along the upper file plate 204 under the action of inertia. The reset spring between the breaking needle 1001 and the upper file plate 204 is compressed by force, and the breaking needle 1001 crushes the residual concrete. Then the reset spring is released and drives the breaking needle 1001 to slide and reset. This can prevent dead corners in the cleaning of residual concrete and ensure the cleaning efficiency of residual concrete.

[0034] A method for treating construction solid waste using a waste treatment device includes the following steps: S1: The extension end of the hydraulic cylinder 301 is extended, so that the drive plate 303 presses against the drive rod 304. The drive rod 304 drives the swing frame 203 to rotate, and the swing frame 203 drives the upper file plate 204 to move until the drive plate 303 disengages from the drive rod 304, so that the upper file plate 204 hits the steel bar to achieve the initial removal of concrete. S2: The upper file plate 204 is limited by the pin 602. When the swing frame 203 rotates and resets, the pin 602 is disengaged from the pin hole of the swing frame 203 by the cooperation of the I-beam 601 and the support frame 801, so that the upper file plate 204 and the lower file plate 202 cooperate to remove the concrete on the steel bar. S3: Through the cooperation of the third cam 702 and the blocking block 704, and the cooperation of the guide rail 901 and the fourth cam 902, the sliding trajectory of the upper file plate 204 is restricted when the compression spring is released, so as to ensure the effect of removing concrete.
