Specific embodiments

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1-4 , the present invention provides a technical solution: a concrete waste separation device for concrete production, including a vertical column 1 and a vibrating screen 3. One end of the vertical column 1 is welded with a spring 2, and one end of the spring 2 is welded with a vibrating screen 3. The surface of the vibrating screen 3 is fixedly installed with a screen mesh 4, both sides of the surface of the screen mesh 4 are fixedly installed with buffer plates 5, a discharge port 6 is arranged on one side of the vibrating screen 3, a feeding hopper 7 is arranged above the vibrating screen 3, a cleaning mechanism 8 is arranged on one side of the vertical column 1, and a screening mechanism 9 is arranged at one end of the vibrating screen 3;

[0021] The screening mechanism 9 includes a screening table 901, a connecting shaft 902, a driving motor 903, a connecting plate 904, a baffle 905, a gauze filter 906, a slag discharge plate 907 and a drain 908. One end of the vibrating screen 3 is fixedly connected to the screening table 901. One end of the screening table 901 is connected to the connecting shaft 902 by bearings. One end of the connecting shaft 902 is connected to the driving motor 903. Both ends of the connecting shaft 902 are sleeved and fixed with the connecting plate 904. A baffle 905 is welded to one side of the connecting plate 904. A gauze filter 906 is fixedly installed on one side of the baffle 905. A slag discharge plate 907 is arranged at one end of the screening table 901. A drain 908 is opened on one side of the screening table 901. Through the settings of the screening table 901, the connecting shaft 902, the driving motor 903, the connecting plate 904, the baffle 905, the gauze filter 906, the slag discharge plate 907 and the drain 908, when in use, the driving motor 903 drives the connecting plates 904 at both ends of the connecting shaft 902 to rotate, so that the connecting plates 904 drive the baffle 905 and the gauze filter 906 to rotate. While the baffle 905 is rotating, the fine residues in the sewage are filtered onto the gauze filter 906. At the same time, the sewage passes through the gauze filter 906 and is discharged from the drain 908 below. The residue part will fall onto the slag discharge plate 907 by rotation and be discharged with vibration, thus completing further separation.

[0022] Further, the buffer plate 5 is inclined and is staggered on both sides of the screen 4. Through the setting of the buffer plate 5, when the concrete waste moves under the jitter of the vibrating screen 3, it will first be blocked by the buffer plate 5, which can slow down the moving speed of the concrete waste, so that the separation is more thorough.

[0023] Further, support members are arranged on both sides of the feeding hopper 7. The feeding hopper 7 is located directly above the screen 4. Through the setting of the feeding hopper 7, when the concrete waste is poured into the feeding hopper 7, it can fall onto the screen 4 below.

[0024] Further, the cleaning mechanism 8 includes a base 801, a water tank 802, a water pump 803, a delivery pipe 804, a connecting pipe 805 and a spray head 806. A base 801 is fixedly installed on one side of the column 1. The water tank 802 is placed on the surface of the base 801. One side of the water tank 802 is connected to the water pump 803. One side of the water pump 803 is connected to the delivery pipe 804. Both ends of the delivery pipe 804 are connected to the connecting pipe 805. A spray head 806 is installed on one side of the connecting pipe 805. Through the settings of the base 801, the water tank 802, the water pump 803, the delivery pipe 804, the connecting pipe 805 and the spray head 806, when in use, the water in the water tank 802 can be pumped out by the water pump 803, then through the delivery pipe 804 and the connecting pipe 805, and finally the concrete waste being screened is washed by the spray head 806, so as to wash away the fine sand on the stones and make the separation more thorough.

[0025] Furthermore, the connecting pipe 805 is located directly above the vibrating screen 3, and the spray nozzles 806 are evenly distributed on one side of the connecting pipe 805. Through the arrangement of the spray nozzles 806, multiple groups of spray nozzles 806 can wash the concrete waste more comprehensively.

[0026] Furthermore, the screening table 901 has a Z-shaped structure, and one side of the connecting plate 904 is close to the right angle of the screening table 901. Through the arrangement of the screening table 901, the screening table 901 can cooperate with the rotating gauze filter screen 906 and the baffle 905 to separate the fine sand.

[0027] Furthermore, the drive motor 903 is fixedly installed on one side of the screening table 901, and the screening table 901 is flush with the lower outlet of the vibrating screen 3. Through the arrangement of the drive motor 903, the baffle 905 and the gauze filter screen 906 on one side of the connecting plate 904 can be driven to rotate.

[0028] Working principle: For the concrete waste separation device used in concrete production, first, the concrete waste to be separated is conveyed to the feeding hopper 7, and then it falls onto the sieve mesh 4 below through the feeding hopper 7. At the same time, the vibration motor on the vibrating screen 3 is started to drive the vibrating screen 3 to vibrate, causing the concrete waste to move. During the movement, through the partition of the buffer plate 5, the moving speed is slowed down. At the same time, the water pump 803 is started to pump the water in the water tank 802 through the water pump 803, then through the conveying pipe 804 and the connecting pipe 805, and finally, the concrete waste being screened is washed through the spray nozzles 806. The fine sand on the stones is washed and falls below the vibrating screen 3, while the stones are discharged through the discharge port 6. The sewage containing fine sand flows below the vibrating screen 3 to the screening table 901. Subsequently, the drive motor 903 is started to drive the baffle 905 and the gauze filter screen 906 on one side of the connecting plate 904 to rotate. During the rotation, the sewage passes through the baffle 905 and then through the gauze filter screen 906. The gauze filter screen 906 separates the fine gravel, and the gravel is thrown onto the slag discharge plate 907 through the rotational inertia. Then, the filtered sewage is discharged through the drain port 908 below.

[0029] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
