[0003] Existing automatic temperature control devices for concrete mixing plants achieve a suitable mixing temperature by heating water and then mixing it with cold water. Traditional mixing involves adding cold water to hot water and using it after temperature detection. However, traditional water mixing is inefficient and cannot meet the needs of today's rapid construction process, thus affecting construction efficiency. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4This utility model provides a technical solution: an automatic temperature control device for production water in a concrete mixing plant, comprising a heating tank 1, a water outlet pipe 2 fixedly connected to the lower end of the heating tank 1, an electromagnetic valve 3 and a water pump 4 fixedly installed on the water outlet pipe 2, a mixing tank 5 fixedly connected to the end of the water outlet pipe 2, a mixing mechanism installed inside the mixing tank 5, a connecting water inlet pipe 7 fixedly connected to the side of the mixing tank 5, one end of the water inlet pipe 7 connected to the heating tank 1, and the other end connected to the mixing tank 5, an electromagnetic valve 3 and a water pump 4 also installed on the water inlet pipe 7, a water pipe 6 fixedly connected to the lower end of the mixing tank 5, an electromagnetic valve 3 and a water pump 4 also installed on the water pipe 6, and a temperature detector 9 fixedly installed on the mixing tank 5; the heating tank 1 is a commonly used automatic temperature control device in concrete mixing plants. One of the devices, the heating tank 1, continuously and automatically heats the water. Automatic heating is a known technology and will not be elaborated on here. This design innovates the piping and mixing method. The outlet pipe 2 at the lower end of the heating tank 1 supplies hot water into the mixing tank 5 through the cooperation of the solenoid valve 3 and the water pump 4. At the other end of the mixing tank 5, the inlet pipe 7 supplies cold water. When the hot and cold water enter the mixing tank 5 at the same time, they are mixed by the mixing mechanism. The temperature detector 9 in the mixing tank 5 monitors the temperature of the water in the mixing tank 5 in real time. When the set temperature is reached, the solenoid valve 3 and the water pump 4 on the water pipe 6 are turned on. Compared with the traditional mixing of cold and hot water, the mixing mechanism can increase the mixing efficiency, thereby achieving a high water efficiency.

[0020] like Figure 4 As shown, the mixing mechanism includes a guide platform 10, which is fixed inside the mixing tank 5. The guide platforms 10 are symmetrically arranged, with their outer ends corresponding to the water outlet pipe 2 and the water inlet pipe 7, respectively. A guide plate 12 is provided below the guide platform 10, and the guide plate 12 is fixedly connected to the inner wall of the mixing tank 5. A gap is provided between the guide plate 12 and the guide platform 10, with a gap of not less than 2 cm. The water from the water outlet pipe 2 and the water inlet pipe 7 is directly impacted onto the guide platform 10 by the action of the water pump 4. The guide plate 12 is fixed at the lower end of the guide platform 10, and there is a gap of not less than 2 cm between the guide platform 10 and the guide plate 12, which changes the columnar water flow into a flat water flow. The hot and cold water can increase the contact area and achieve a rapid mixing effect.

[0021] like Figure 2 and Figure 4As shown, the mixing mechanism also includes a motor 8, which is fixed to the upper end of the mixing tank 5 by a bracket. The output end of the motor 8 is fixedly connected to a rotating rod 13, which passes through the mixing tank 5 and extends to the bottom. A stirring plate 14 is fixedly connected to the side wall of the rotating rod 13 at the bottom of the mixing tank 5, and a through hole 15 is provided on the stirring plate 14. The motor 8 is fixed to the upper end of the mixing tank 5, and the motor 8 drives the rotating rod 13 to rotate. A stirring plate 14 is fixed to the lower end of the rotating rod 13, and a through hole 15 is provided on the stirring plate 14. When the rotating rod 13 rotates, it re-mixes the water that has been initially mixed at the upper end, further improving the mixing rate and thus increasing the mixing efficiency.

[0022] like Figure 4 As shown, the outer end face of the guide platform 10 is provided with an arc-shaped surface 11; the arc-shaped surface 11 can reduce the impact force of water, thereby reducing the noise generated inside and also reducing the impact wear on the guide platform 10.

[0023] like Figure 3 As shown, the temperature detector 9 is a probe type and is located on the side wall of the mixing tank 5, extending to the bottom of the mixing tank 5. The temperature detector 9 is a probe type and extends from the upper inner side of the mixing tank 5 to the bottom. This allows for real-time detection of the internal water temperature without affecting the rotation of the stirring plate 14, thus not affecting the mixing.

[0024] like Figure 4 As shown, the perforation 15 is arranged in a strip shape; the strip-shaped perforation 15 can increase the amount of water flowing through, reduce the shaking of the stirring plate 14, and thus reduce the overall shaking of the mixing tank 5.

[0025] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
