DETAILED DESCRIPTION
[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0017] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention.
[0018] Below, the separation device for waste concrete processing according to the embodiment of the utility model is described with reference to the accompanying drawings. Figures 1 to 5As shown, the separation equipment for processing waste concrete includes a fuselage 1 and a feed port 101 arranged on the top of the fuselage 1, and support legs 105 are arranged at the four corners of the bottom of the fuselage 1. The characteristics are: a discharge port 104 is arranged on one side of the bottom of the fuselage 1, and a first shaft rod 3 and a second shaft rod 4 are rotatably installed in the fuselage 1 through bearings, a motor 2 is fixedly installed on the side wall of the fuselage 1, and the output end of the motor 2 is fixedly connected to the first shaft rod 3, and a plurality of supports 8 are also arranged in the fuselage 1, and a sieve plate 7 is installed on each support 8, wherein a bearing is arranged between the first shaft rod 3, the second shaft rod 4 and the fuselage 1, and the first shaft rod 3 and the second shaft rod 4 can rotate in the bearings to prevent the first shaft rod 3 and the second shaft rod 4 from rubbing against the fuselage 1.
[0019] Preferably, a first discharge port 102 is opened on one side of the fuselage 1, and a second discharge port 103 is opened on the other side of the fuselage 1. There are two supports 8, which are staggered up and down, and the apertures of the sieve holes on the two sieve plates 7 increase from top to bottom.
[0020] Preferably, a material guide plate 9 is connected to one side of the bottom of the two supports 8, and the material guide plate 9 is inclined. The two material guide plates 9 are staggered up and down, and one side of the upper material guide plate 9 is connected to the first discharge port 102, and one side of the lower material guide plate 9 is connected to the second discharge port 103.
[0021] Preferably, one end of the sieve plate 7 is hinged to the support 8 , and the other end of the sieve plate 7 is symmetrically provided with a spring 801 , the bottom of the spring 801 is fixed on the support 8 , and the sieve plate 7 can rotate around one side of the support 8 .
[0022] In a specific embodiment: when in use, the crushed waste concrete is poured into the fuselage 1 from the feed port 101, and the concrete will fall onto the upper sieve plate 7. Under the impact of the concrete, the sieve plate 7 will rotate downward and compress the spring 801. After the spring 801 is compressed, a reaction force will be generated to rotate the sieve plate 7 upward, thereby realizing the reciprocating swing of the sieve plate 7 under the action of the spring 801, thereby speeding up the screening speed of the sieve plate 7 for the concrete, reducing the time required for screening, and achieving the effect of improving the screening efficiency. The concrete screened by the upper sieve plate 7 The soil will fall to the lower sieve plate 7 for secondary screening. Since the sieve hole diameter of the lower sieve plate 7 is larger than the sieve hole diameter of the upper sieve plate 7, concrete of different particle sizes can be screened step by step. There is no need to replace the sieve plate 7 during separation. The steps are simple, which improves the efficiency of concrete separation and makes the concrete separation process more convenient. The concrete particles screened by the upper sieve plate 7 will fall on the upper guide plate 9 and be discharged from the first discharge port 102. The concrete particles screened by the lower sieve plate 7 will fall on the lower guide plate 9 and be discharged from the second discharge port 104.
[0023] Preferably, a plurality of support rods 6 are disposed on the side walls of the first shaft rod 3 and the second shaft rod 4 , and the support rods 6 are equidistantly arranged around the side walls. The first shaft rod 3 is located below the feed port 101 .
[0024] Preferably, a first pulley 301 is provided at one end of the first shaft 3, a second pulley 401 is provided at one end of the second shaft 4, and a transmission belt 5 is provided between the first pulley 301 and the second pulley 401 for connection.
[0025] In a specific embodiment: when the crushed waste concrete is separated, by starting the motor 2, the motor 2 will drive the first shaft rod 3 to rotate, and the rotation of the first shaft rod 3 will drive the first pulley 301 to rotate synchronously. Since the first pulley 301 is connected to the second pulley 401 through the transmission belt 5, the rotation of the first pulley 301 will drive the second pulley 401 to rotate synchronously, and the second shaft rod 4 is driven to rotate through the second pulley 401. Since a plurality of support rods 6 are equidistantly arranged on the first shaft rod 3 and the second shaft rod 4, the concrete put into the fuselage 1 can be broken up by the rotating support rods 6 to avoid the phenomenon of concrete agglomeration, thereby improving the screening effect of the screen plate 7 on the concrete.
[0026] Working principle: When in use, the crushed waste concrete is poured into the fuselage 1 from the feed port 101, and the concrete will fall onto the upper sieve plate 7. Under the impact of the concrete, the sieve plate 7 will rotate downward and compress the spring 801. After the spring 801 is compressed, a reaction force will be generated to rotate the sieve plate 7 upward, thereby realizing the reciprocating swing of the sieve plate 7 under the action of the spring 801, thereby speeding up the screening speed of the sieve plate 7 for concrete, reducing the time required for screening, and achieving the effect of improving the screening efficiency. The concrete screened by the upper sieve plate 7 will fall to the lower sieve plate 7 for secondary screening. During the secondary screening, since the sieve hole diameter of the lower sieve plate 7 is larger than the sieve hole diameter of the upper sieve plate 7, concrete of different particle sizes can be screened out step by step. There is no need to replace the sieve plate 7 during separation. The steps are simple, which improves the efficiency of concrete separation and makes the concrete separation process more convenient. At the same time, a first shaft rod 3 and a second shaft rod 4 are arranged in the fuselage 1, and a plurality of support rods 6 are equidistantly arranged on the first shaft rod 3 and the second shaft rod 4. The rotating support rods 6 can break up the concrete put into the fuselage 1 to avoid the agglomeration of the concrete, thereby improving the screening effect of the sieve plate 7 on the concrete.
