Description

Technical Field

[0001] The utility model relates to the technical field of concrete waste recycling, and particularly relates to a heavy pressure separation device for concrete waste recycling. Background Art

[0002] Concrete is a commonly used building material, usually composed of cement, aggregates (such as sand and stones), water, and possibly added admixtures and blending materials mixed and stirred in a certain proportion. In the production process of concrete production enterprises, equipment directly contacting concrete such as concrete mixing stations, pump trucks, and tank trucks are required. Since concrete will solidify into hard blocks in a short time and has a certain corrosiveness to steel and paint, after each use, the concrete waste in the above equipment needs to be unloaded and the equipment needs to be cleaned.

[0003] At the same time, during the construction process, the estimated amount of concrete is generally more than the actual required amount. Therefore, there is often surplus concrete. The unloaded concrete waste has been contaminated and exposed to the external environment. The concrete is prone to caking and solidification, and cannot be recycled and reused, resulting in serious waste of production materials, increasing the losses of concrete production enterprises, and direct discharge will pollute the environment.

[0025] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, the technical solution in the embodiment of the present application effectively solves the technical problem that the redundant concrete waste has been polluted and exposed to the external environment, the concrete is easy to agglomerate and solidify, cannot be recycled and reused, resulting in serious waste of production materials, increasing the losses of concrete production enterprises, and direct discharge will pollute the environment. The general idea is as follows:

[0026] In view of the problems existing in the prior art, the utility model provides a heavy pressure separation device for concrete waste recycling, which includes a recycling tank 1. A filtering component is arranged inside the recycling tank 1. The filtering component includes a first filter plate 18, a support shaft 19, and a second filter plate 22. A first stirring rod 17 is fixedly installed at the top end of the support shaft 19. A second stirring rod 21 is fixedly installed on the surface of the support shaft 19. A bottom plate 26 is fixedly installed at the bottom end of the recycling tank 1. A discharge pipe 15 is fixedly installed at the bottom end of the bottom plate 26. The support shaft 19 rotates idly inside the first filter plate 18 and the second filter plate 22. The outer sides of the first filter plate 18 and the second filter plate 22 are fixedly connected to the inner side wall of the recycling tank 1.

[0027] A rotating shaft 23 is rotatably installed inside the bottom plate 26. At least two third stirring rods 24 are fixedly installed on the surface of the rotating shaft 23. The top end of the rotating shaft 23 is fixedly connected to the support shaft 19. At the same time, the third stirring rod 24 itself is bent and fits the inner wall of the rotating shaft 23. A first discharge pipe 13 is fixedly installed on the outer side of the recycling tank 1. A second discharge pipe 14 is fixedly installed on the outer side of the recycling tank 1. A top cover 11 is fixedly installed at the top end of the recycling tank 1. A feeding pipe 12 is fixedly installed at the top end of the top cover 11. A water supply pipe 25 is fixedly installed at the top end of the top cover 11. A flow dividing plate 16 is fixedly installed at the bottom end of the top cover 11.

[0028] Working principle:

[0029] In the first step, a motor is connected to one side of the recycling tank 1. The support shaft 19 is driven to rotate by the motor. The concrete waste is input into the recycling tank 1 from the feeding pipe 12. Water is introduced into the recycling tank 1 through the water supply pipe 25. At the same time, the motor is started. The motor drives the support shaft 19 to rotate. The support shaft 19 rotates idly inside the first filter plate 18 and the second filter plate 22. However, the first stirring rod 17 and the second stirring rod 21 follow the support shaft 19 to rotate. The first stirring rod 17 and the second stirring rod 21 rotate above the first filter plate 18 and the second filter plate 22 respectively. After the concrete waste meets water, sand and stones are separated under the continuous stirring of the first stirring rod 17 and the second filter plate 22. Through the stirring effect, the materials adhered to the sand and stones are more likely to be separated. After the concrete waste first passes through the filtration of the first filter plate 18, the impurities pass through the first filter plate 18 and then continue to fall onto the surface of the second filter plate 22. The stones and sand are respectively isolated on the first filter plate 18 and the second filter plate 22. At the same time, a first discharge pipe 13 and a second discharge pipe 14 are fixedly installed on the outer side of the recycling tank 1. The first discharge pipe 13 and the second discharge pipe 14 are respectively connected to the first filter plate 18 and the second filter plate 22. The waste filtered by the first filter plate 18 and the second filter plate 22 is discharged through the first discharge pipe 13 and the second discharge pipe 14 respectively for classification, and different wastes are introduced into different treatment boxes.

[0030] Second step, a diverter plate 16 is installed at the bottom end of the material conveying pipe 12. The material conveying pipe 12 conveys the concrete waste to the inside of the recycling tank 1. The waste first collides with the diverter plate 16. The top end of the diverter plate 16 is designed in a conical shape to expand the dispersion area of the waste. Through the continuous stirring of the first stirring rod 17 and the second stirring rod 21 and the action of water flow, the sand and stones on the surfaces of the first filter plate 18 and the second filter plate 22 become cleaner. At the same time, the water and other impurities entering the inside of the recycling tank 1 flow to the bottom of the recycling tank 1 under the action of gravity and are discharged through the discharge pipe 15. By setting the third stirring rod 24, the rotating shaft 23 and the third stirring rod 24 are integrally designed. The support shaft 19 drives the rotating shaft 23 to rotate, so that the third stirring rod 24 continuously stirs inside the bottom plate 26 to prevent the impurities in the water from sticking to the bottom of the recycling tank 1. Open the discharge pipe 15 to discharge the sewage and further process it to complete the separation, and collect and reuse the sand and stones in the concrete waste.

[0031] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly illustrating the present invention, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
