[0021] The present application will be further described in detail below with reference to the accompanying drawings.
[0022] This application discloses an anti-clogging sand screening device for building construction.
[0023] Reference Figure 1 , Figure 2 The anti-clogging sand screening device for building construction includes a sand screening frame 1, on which a sand screening cylinder 2 driven by a motor is rotatably mounted. The sand screening cylinder 2 is inclined downwards, and a feed hopper 3 is fixedly installed on the top of the sand screening frame 1, located on one side of the sand screening cylinder 2. The discharge port at the lower end of the feed hopper 3 extends into the sand screening cylinder 2. By pouring sand and gravel into the feed hopper 3 from the top feed hopper 3, the sand and gravel will eventually be discharged into the sand screening cylinder 2 from the lower discharge port of the feed hopper 3. The outer wall of the sand screening cylinder 2 is equipped with two sections of screens with different aperture sizes. By starting the motor, the sand screening cylinder 2 is driven to rotate. As the sand screening cylinder 2 rotates, the screens can screen sand and gravel of different sizes. Sand and gravel smaller than the mesh size of the screen can pass through the screen and fall from the bottom of the sand screening cylinder 2.
[0024] like Figure 1 , Figure 2 As shown, a first screening bin 11 and a second screening bin 12 are fixedly installed at the bottom of the sand screening frame 1, located below the sand screening cylinder 2. The first screening bin 11 and the second screening bin 12 are arranged sequentially along the length of the sand screening cylinder 2. The first screening bin 11 and the second screening bin 12 are respectively located below the corresponding screens. After being screened by the screens, sand and gravel of the same specification will fall into the corresponding first screening bin 11 or second screening bin 12 respectively. Finally, the sand and gravel of the same specification can be collected uniformly through the first screening bin 11 and the second screening bin 12.
[0025] like Figure 2 , Figure 3As shown, multiple assembly discs 9 are coaxially fixed on the rotating shaft of the sand screening cylinder 2, and the assembly discs 9 are arranged sequentially at intervals along the length of the rotating shaft of the sand screening cylinder 2. Multiple support rods 90 are circumferentially spaced and fixed on the outer wall of the assembly discs 9, and the length of the support rods 90 extends radially along the sand screening cylinder 2. Multiple reinforcing rods 22 are circumferentially spaced on the inner wall of the sand screening cylinder 2, and the length of the reinforcing rods 22 extends along the length of the rotating shaft of the sand screening cylinder 2. The end of the support rod 90 away from the assembly disc 9 is connected and fixed to its corresponding reinforcing rod 22. The screen is fixedly installed on the outside of the reinforcing rod 22. The reinforcing rods 22 and the support rods 90 are used to support and fix the screen to enhance its structural strength.
[0026] like Figure 1 As shown, a dust cover 4 is detachably installed on the sand screening frame 1, covering the top of the sand screening cylinder 2. The bottom wall of the dust cover 4 is fixedly provided with a plurality of threaded posts 40 facing the sand screening frame 1. The sand screening frame 1 is provided with mounting holes 10 corresponding to the threaded posts 40 one by one. The threaded posts 40 are respectively inserted into their respective mounting holes 10. The ends of the threaded posts 40 are threadedly connected with fastening nuts 41 for tightening and fixing the dust cover 4 onto the sand screening frame 1.
[0027] like Figure 2 , Figure 3 As shown, multiple sets of mounting seats 5 are fixedly installed on the inner wall of the dustproof seat 4. The mounting seats 5 are arranged evenly and sequentially along the rotation direction of the sand screening cylinder 2. The mounting seats 5 in the same group are arranged sequentially and sequentially along the length direction of the sand screening cylinder 2, and the central axis of the mounting seat 5 is set along the radial direction of the sand screening cylinder 2. A connecting rod 50 is coaxially arranged inside the mounting seat 5. One end of the connecting rod 50 is limited inside the mounting seat 5, and the other end of the connecting rod 50 extends from the outer wall of the mounting seat 5 and faces the outer wall of the sand screening cylinder 2.
[0028] like Figure 2 , Figure 3 As shown, the connecting rod 50 slides along the central axis of the mounting base 5. A return spring 51 is provided inside the mounting base 5, and the return spring 51 extends and retracts along the sliding direction of the connecting rod 50. One end of the return spring 51 abuts against the inner sidewall of the mounting base 5, and the other end of the return spring 51 abuts against the connecting rod 50. The return spring 51 is used to push the connecting rod 50 to move closer to the sand screening cylinder 2.
[0029] like Figure 2 , Figure 3As shown, a guide wheel 52 is rotatably mounted on one end of the connecting rod 50 facing the sand screening cylinder 2, and the rotation axis of the guide wheel 52 is in the same direction as the rotation axis of the sand screening cylinder 2. Multiple reinforcing rings 20 are coaxially fixed on the outer wall of the sand screening cylinder 2, each opposite to the guide wheel 52, and are arranged at intervals along the length of the sand screening cylinder 2. Under the elastic force of the return spring 51, the guide wheel 52 abuts against the outer wall of its respective reinforcing ring 20.
[0030] like Figure 2 , Figure 3 As shown, multiple circumferentially arranged inclined seats 21 are fixedly installed on the outer circumferential surface of the reinforcing ring 20, and the guide wheels 52 are respectively located on the rotation path of their respective inclined seats 21. When the inclined seat 21 rotates with the sand screening cylinder 2 to be directly opposite the guide wheel 52, the guide wheel 52 will gradually rise along the slope on one side of the inclined seat 21. At this time, the guide wheel 52 will push the connecting rod 50 to gradually compress the return spring 51. When the guide wheel 52 successfully passes the inclined seat 21, the guide wheel 52 will quickly return to its original position under the elastic force of the return spring 51 and impact the reinforcing ring 20. The vibration generated by the impact can shake off some of the sand and gravel stuck on the screen, thereby achieving the effect of preventing blockage.
[0031] like Figure 2 , Figure 3 As shown, a connecting frame 6 is fixedly installed between two adjacent connecting rods 50 in the same group. The connecting frame 6 is located between two adjacent reinforcing rings 20, and the connecting frame 6 connects and fixes each connecting rod 50 in the same group in sequence. The length of the connecting frame 6 extends along the length direction of the sand screening cylinder 2, and a cleaning brush 60 facing the outer wall of the sand screening cylinder 2 is fixedly installed on the connecting frame 6. When the guide wheel 52 contacts the surface of the reinforcing ring 20, the cleaning brush 60 will be inserted into the mesh of the screen. The cleaning brush 60 can clean the surface of the screen in real time, thereby effectively preventing the screen from being blocked by sand and gravel.
[0032] When the guide wheel 52 periodically and rapidly impacts the reinforcing ring 20 under the action of the inclined seat 21, the cleaning brush 60 will periodically push the sand and gravel stuck on the screen out of the mesh under the drive of the connecting frame 6, thereby further improving the screen's anti-clogging effect.
[0033] like Figure 2 , Figure 3 As shown, an extension plate 61 is also fixedly installed on one side of the connecting frame 6, located between two adjacent reinforcing rings 20. Three beating elements 7 are fixedly installed on the extension plate 61, facing the outer wall of the sand screening cylinder 2. The beating elements 7 slide synchronously with the connecting rod 50 and are used to periodically beat the outer surface of the sand screening cylinder 2. Through the beating of the beating elements 7, sand and gravel stuck in the mesh can be shaken off, thereby further improving the anti-clogging effect.
[0034] like Figure 1 As shown, a spray pipe 8 with its spray nozzle facing the sand screening cylinder 2 is also fixedly installed on the inner wall of the dustproof seat 4. The water inlet of the spray pipe 8 is used to connect to an external water pipe. The surface of the screen can be cleaned by spraying through the spray pipe 8.
[0035] The implementation principle is as follows: When the inclined seat 21 rotates with the sand screening cylinder 2 to be directly opposite the guide wheel 52, the guide wheel 52 will gradually rise along the slope on one side of the inclined seat 21. At this time, the guide wheel 52 will push the connecting rod 50 to gradually compress the return spring 51. When the guide wheel 52 successfully passes the inclined seat 21, the guide wheel 52 will quickly return to its original position under the elastic force of the return spring 51 and hit the reinforcing ring 20. The vibration generated by the impact can shake off some of the sand and gravel stuck on the screen, thereby achieving the effect of preventing blockage.
[0036] The cleaning brush 60 can clean the screen surface in real time, effectively preventing the screen from being clogged by sand and gravel. When the guide wheel 52 periodically and rapidly impacts the reinforcing ring 20 under the action of the inclined seat 21, the cleaning brush 60, driven by the connecting frame 6, periodically pushes the sand and gravel stuck on the screen out of the mesh, thereby further improving the screen's anti-clogging effect. Similarly, the beating of the tapping member 7 can shake off the sand and gravel stuck on the screen, further enhancing the anti-clogging effect.
[0037] 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.
