Description

Technical Field

[0001] The utility model relates to the technical field of concrete sand and gravel devices, and particularly relates to a device for recycling waste slurry water of sand and gravel in a concrete mixing plant. Background Technique

[0002] In the environment of the great development of urbanization, the development and application of resource-saving and environment-friendly products have become more and more common. Concrete mixing plants are in a core position in the commercial concrete industry, undertaking the important task of supplying commercial concrete for housing construction projects and infrastructure construction projects, and the output has been increasing year by year. After the tank trucks of commercial concrete mixing plants transport the concrete to the construction site for pouring and then return to the mixing plant, it is necessary to add water to the tank to wash out the residual concrete in the tank, thus generating waste slurry and waste water. The environmental protection problems such as the difficulty of discharging and treating the waste slurry and waste water seriously restrict the long-term development of commercial concrete mixing plants. Recycling the waste slurry water can effectively solve the discharge of waste water and waste slurry, which not only conforms to the national and company's environmental protection development strategies, but also will bring certain economic benefits to the company.

[0003] Chinese patent document CN219217796U discloses a device for recycling waste slurry water of sand and gravel in a concrete mixing plant, which relates to the field of concrete sand and gravel devices. It includes a collection cylinder, and also includes a reaction component and a precipitation component.

Detailed implementation mode

[0025] The technical means, creative features, achieved purposes and effects realized by the present utility model are easy to understand. The present utility model will be further described below in conjunction with the detailed implementation mode.

[0026] As Figure 1 shown, a device for recycling and reusing sand, gravel and waste slurry water in a concrete mixing plant includes a filtering device 1. The upper end of the filtering device 1 is fixedly connected with a feed hopper 6. The middle part of the lower end of the filtering device 1 is fixedly connected with a connecting pipe 7. The lower end of the connecting pipe 7 is fixedly connected with a reaction device 2. The upper end of the reaction device 2 is fixedly connected with an acid adding device 3. The left end of the reaction device 2 is fixedly connected with a sand and gravel collecting device 8. The right end of the reaction device 2 is fixedly connected with a liquid pumping pump 4. The right end of the liquid pumping pump 4 is fixedly connected with a precipitation device 5.

[0027] As Figure 2 shown, the filtering device 1 includes a filter box 11. The left inner wall of the filter box 11 is fixedly connected with a first filter plate 12. A second filter plate 13 is arranged below the first filter plate 12. The middle parts of the front and rear ends of the second filter plate 13 are fixedly connected with vibration motors 17. The front and rear ends of the second filter plate 13 are fixedly connected with two fixed columns 14. One end of the fixed column 14 is fixedly connected with a telescopic spring 15. One end of the telescopic spring 15 is fixedly connected with the inner wall of the filter box 11. The surface of the fixed column 14 is movably connected with a fixed sleeve 16. The telescopic spring 15 is located inside the fixed sleeve 16. One end of the fixed sleeve 16 is fixedly connected with the inner wall of the filter box 11. The left end of the filter box 11 is provided with a discharge port 18.

[0028] In this embodiment, the waste slurry water enters the inside of the filter box 11 through the feed hopper 6. The waste slurry water reaches the second filter plate 13 through the first filter plate 12. The vibration motor 17 is controlled to vibrate, so that the fixed column 14 squeezes the telescopic spring 15 inside the fixed sleeve 16, and further makes the second filter plate 13 vibrate back and forth inside the filter box 11. It can not only filter out the sand and gravel, but also shake off the waste slurry water attached to the sand and gravel, improving the recycling efficiency.

[0029] As Figure 3 shown, the reaction device 2 includes a reaction barrel 21. A stirring motor 22 is fixedly connected to the lower end of the reaction barrel 21. The output end of the stirring motor 22 is fixedly connected to a rotating shaft 23. Stirring blades 24 are fixedly connected to the surface of the rotating shaft 23.

[0030] In this embodiment, by controlling the rotation of the stirring motor 22, the rotating shaft 23 is driven to rotate, and then the stirring blades 24 stir the waste pulp water inside the reaction barrel 21, so that the waste pulp water and the acid solution are fully fused and reacted.

[0031] As Figure 4 shown, the acid adding device 3 includes an acid solution tank 31. An acid inlet pump 32 is fixedly connected to the left end of the acid solution tank 31. A acid guiding pipe 33 is fixedly connected to the left end of the acid inlet pump 32. An anti-corrosion valve 34 is fixedly connected to the surface of the acid guiding pipe 33. An acid inlet head 35 is fixedly connected to the lower end of the acid guiding pipe 33.

[0032] In this embodiment, by opening the anti-corrosion valve 34, the acid inlet pump 32 pumps out the acidic solution from inside the acid solution tank 31, passes through the acid guiding pipe 33 to reach the acid inlet head 35, and finally enters the reaction barrel 21 to reduce the pH value of the waste pulp water.

[0033] As Figure 5 shown, the precipitation device 5 includes a precipitation barrel 51. A limiting groove 52 is formed in the inner right wall of the precipitation barrel 51. A fixing block 53 is fixedly connected to the upper side inside the limiting groove 52. A rotating motor 54 is fixedly connected to the upper end of the fixing block 53. The output end of the rotating motor 54 is fixedly connected to a threaded rod 55. A threaded block 56 is threadedly connected to the surface of the threaded rod 55. A lifting block 57 is fixedly connected to the left end of the threaded block 56. A water pump 58 is fixedly connected to the upper end of the precipitation barrel 51. A telescopic pipe 59 is fixedly connected to the lower end of the water pump 58. The lower end of the telescopic pipe 59 is fixedly connected to one end of the lifting block 57.

[0034] In this embodiment, after the waste pulp water precipitates, by controlling the rotation of the rotating motor 54, the threaded rod 55 rotates on the fixing block 53, and then the threaded block 56 moves inside the limiting groove 52, driving the lifting block 57 to rise and fall, bringing the lower end of the telescopic pipe 59 to the boundary between the mud and water in the precipitation barrel 51, and the water inside the precipitation barrel 51 can be pumped out by the water pump 58.

[0035] The working principle of the utility model is as follows: The waste pulp water enters the interior of the filtration tank 11 through the feed hopper 6. The waste pulp water reaches the second filter plate 13 after passing through the first filter plate 12. The vibration motor 17 is controlled to vibrate, so that the fixed column 14 squeezes the telescopic spring 15 inside the fixed sleeve 16, and then the second filter plate 13 vibrates back and forth inside the filtration tank 11. This can not only filter out the sand and gravel, but also shake off the waste pulp water attached to the sand and gravel, improving the recycling efficiency. By opening the anti-corrosion valve 34, the acid inlet pump 32 pumps out the acidic solution from the interior of the acid solution tank 31, passes through the acid guide pipe 33 to reach the acid inlet head 35, and finally enters the reaction barrel 21 to reduce the pH value of the waste pulp water. By controlling the rotation of the stirring motor 22, the rotating shaft 23 is driven to rotate, and then the stirring blades 24 stir the waste pulp water inside the reaction barrel 21, enabling the waste pulp water and the acid solution to fully react by mixing. After the waste pulp water precipitates, by controlling the rotation of the rotating motor 54, the threaded rod 55 rotates on the fixed block 53, and then the threaded block 56 moves inside the limiting groove 52, driving the lifting block 57 to move up and down, bringing the lower end of the telescopic pipe 59 to the boundary between the mud and water in the sedimentation barrel 51. The water inside the sedimentation barrel 51 can be pumped out through the water pump 58.

[0036] The above text has generally described the utility model in detail. However, based on the utility model, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, modifications or improvements that do not depart from the spirit of the utility model are within the protection scope of the utility model.
