Description

Technical Field

[0001] This utility model relates to the field of concrete treatment, and in particular to a wastewater mixing system for concrete mixing plants. Background Technology

[0002] In recent years, with the increasing public awareness of environmental protection, the environmental issues of concrete mixing plants have received more and more attention. Dust pollution, noise pollution, and wastewater discharge have become important factors restricting the development of traditional concrete mixing plants. Building modern, green, and environmentally friendly mixing plants is an inevitable trend, a necessary requirement for accelerating the construction of a resource-saving and environmentally friendly society, and a key to achieving sustainable development in the concrete industry.

[0003] During the construction of concrete mixing plants, a large amount of wastewater is generated. This wastewater is not only highly alkaline but also contains sand, gravel, and incompletely hydrated cementitious materials. If left untreated, it wastes resources, clogs municipal facilities, and pollutes rivers, seriously harming the environment. Therefore, it is essential to treat and recycle this wastewater, replacing some of the production water. This ensures concrete quality, improves the hygiene of the mixing plant, protects the ecological environment, conserves water resources, and brings economic benefits. Currently, wastewater mixing plants suffer from low wastewater treatment efficiency and are prone to secondary pollution, problems that urgently need to be addressed to promote green and environmentally friendly construction practices.

Detailed Implementation

[0016] The present invention will be further described below with reference to embodiments. The description of the embodiments below is only for the purpose of helping to understand the present invention. It should be noted that, for those skilled in the art, several modifications can be made to the present invention without departing from the principle of the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.

[0017] As one embodiment, this wastewater mixing system for a concrete mixing plant includes a first inlet 1, a control valve 2, a wastewater treatment agent tank 3, a flow guide 4, a mixing motor 7, a drill rod 8, a wastewater pump 10, a PLC intelligent control console 13, a level gauge 15, a wastewater concentration tester 17, a wastewater mixing tank 18, and a containerized structural panel 19.

[0018] The wastewater mixing tank is equipped with a wastewater mixing drill rod 8, on which long mixing blades 5 and short mixing blades 9 are arranged in a crisscross pattern. A flow guide 4 is also arranged near the mixing blades. The mixing motor 7 is welded and fixed by a fixing frame 6. The wastewater treatment agent tank 3 is located at the upper left of the wastewater mixing system and is controlled by a control valve 2 to allow the wastewater treatment agent to flow into the wastewater mixing tank 18. The wastewater mixing tank 18 is connected to a wastewater concentration regulating tank on its right side. The wastewater concentration regulating tank is equipped with a wastewater concentration tester 17 and a level gauge 15. The PLC intelligent electronic control console 13 is located on the right side of the wastewater concentration regulating tank.

[0019] Specifically, the wastewater mixing tank 18 pumps mortar water to the wastewater concentration regulating tank via the wastewater pump 10. When the wastewater concentration tester 17 detects that the wastewater concentration is too high, it automatically opens the clean water inlet 12 to inject clean water until the wastewater concentration meets the requirements for reuse. The PLC intelligent electronic control console 13 can adjust parameters such as the wastewater mixing rate and wastewater concentration regulation according to actual working conditions, reducing the workload of staff. The wastewater mixing system adopts a container design, making it easy to transport, install, and dismantle.

[0020] Example 2

[0021] As another embodiment, this second embodiment, based on the first embodiment, proposes a concrete batching plant wastewater mixing system. The specific steps for wastewater mixing using this system are as follows:

[0022] Wastewater enters the wastewater mixing tank 18 through the first inlet 1. The control valve 2 at the wastewater treatment agent tank is opened, injecting the wastewater treatment agent into the mixing tank 18. The wastewater mixing motor 7 is fixed to the upper part of the mixing tank 18 via a mounting bracket 6. The mixing motor 7 operates at a set mixing rate according to the PLC intelligent control console 13 to prevent wastewater sedimentation. Long mixing blades 5 and short mixing blades 9 are distributed crosswise on the mixing drill rod 8. Guide components 4 are arranged near the mixing blades to ensure uniform mixing of the wastewater treatment agent and wastewater. After mixing, the wastewater is pumped by the wastewater pump 10 to the wastewater concentration regulating tank on the right. A wastewater concentration tester 17 and a level gauge 15 are installed at the bottom of the regulating tank to measure the wastewater concentration and level in real time. When the wastewater concentration is too high, a clean water replenishment device is automatically activated, injecting clean water into the regulating tank through the clean water inlet 12. Once the wastewater concentration reaches the required level, it flows through the outlet 14 into the mixing host or the tanker cleaning pipeline for reuse.

[0023] As an improved embodiment, when the wastewater concentration measured by the wastewater concentration tester 17 is too high in the wastewater concentration regulating tank, the stirring rate of the stirring rod 8 in the wastewater mixing tank can be increased through the PLC intelligent control console 13 to ensure that the wastewater treatment agent reacts fully with the wastewater and reduces the wastewater concentration.

[0024] It should be noted that the parts in this embodiment that are the same as or similar to those in Embodiment 1 can be referred to each other, and will not be repeated in this application.

[0025] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
