Description

Concrete mixing transport vechicle sprays cooling system

Technical Field

The utility model relates to a concrete mixing transport vechicle cooling technical field, specific concrete mixing transport vechicle automatic spray and cooling system that says so, it plays the cooling effect when high temperature weather transportation concrete in summer, less concrete slump loss.

Background

Concrete pumping construction has higher requirements on concrete, and particularly shows that the concrete has better workability and higher fluidity. In the actual construction process, the slump of the fresh concrete is gradually reduced under the influence of factors such as materials, time and the like, in addition, the temperature of the concrete is also an important factor influencing the slump, and the higher the temperature is, the greater the slump loss of the concrete is. Particularly in summer, the outdoor temperature can reach 40 ℃, the surface temperature can reach more than 60 ℃, and the slump loss of the concrete is large under the actions of self hydration heat release and heat absorption of the transportation tank truck.

Disclosure of Invention

In order to reduce because of shining in summer and lead to the problem that the temperature is too high in the concrete transportation jar car, influences the concrete slump, the utility model provides a concrete mixing transport vechicle sprays cooling system can open spraying system when temperature is higher in summer, plays the cooling function, has the effect of wasing the jar body simultaneously in addition, and cyclic utilization is realized to all water usages, avoids extravagant.

The utility model provides a technical scheme that its technical problem adopted is:

the concrete mixing transport vechicle sprays cooling system, its structure includes water tank, spray set, temperature control device, water collection device. The spraying device is a water pipe with a water mist spray head, one end of the water pipe is fixed at the tail part of the tank body, the other end of the water pipe is connected to a water tank of the concrete mixing and transporting truck, and an electromagnetic valve is arranged at the end close to the water tank; the temperature control device feeds the temperature of the tank body back to the PID multi-path controller through a wireless infrared sensor; the collecting device is positioned at the bottom of the tank body and used for collecting water falling from the tank body, and the water level controller inside the tank body can feed back signals to the PID controller when the collecting device is about to be filled with water, so that the water pump connected with the collecting device is started. The good cooling effect to the concrete mixing transport vechicle jar body is realized to circulation like this.

Compared with the prior art, the utility model produced beneficial effect is:

in summer high-temperature weather, the temperature of the tank body of the concrete mixing truck can be effectively reduced, and the slump loss of concrete caused by the temperature is reduced; the structure is simple, the design is automatic, the spraying system can be automatically started to cool in high-temperature weather, and the spraying system can be automatically closed when the temperature is reduced to be below the set temperature, and manual control is not needed; the tank body can be washed and cleaned while the temperature is reduced, so that the tank body is kept clean; the cyclic utilization of water resources of the spraying system is realized, and the waste is reduced.

Drawings

The present invention will be further explained with reference to the drawings and examples.

Fig. 1 is a perspective view of the present invention.

In the figure, 1, a water tank, 2, a water pipe, 3, a water spray nozzle, 4, a temperature sensing element, 5, an electromagnetic valve, 6, a water collecting tank, 7, a water level controller, 8, a water pump, 9, a water return pipe and 10, a PID multi-path controller are adopted.

Detailed Description

For better explanation of the present invention, the technical solution will now be further explained with reference to the specific embodiments and the drawings.

As shown in the attached figure 1, the utility model discloses a concrete mixing transport vechicle sprays cooling system, its structure includes water tank 1, spray set, temperature control device, water collection device.

The spraying device comprises a water pipe 2, a water mist spray head 3 and an electromagnetic valve 5, the front end of the water pipe 2 is fixedly connected with a self-contained water tank of the concrete mixing transport vehicle and controls a water flow switch through the electromagnetic water valve 5, and the tail end of the water pipe is fixed at the tail part of a transport vehicle tank; the water spray nozzles 3 are arranged on the whole water pipe at intervals, and the distance between the water spray nozzles and the tank body is not too far. The temperature control device mainly comprises an infrared temperature sensing element 4 fixed in the middle of the tank body and a PID multi-path controller fixed in a cab; the water collecting device comprises a water collecting tank 6, a water level controller 7 and a water pump 8, water sprayed on the tank body flows to the bottom of the tank body and collects the water collecting tank 6, the water collecting tank is full of water, the water level controller 7 feeds back signals to a PID (proportion integration differentiation) controller, and the water pump 7 pumps the water into the water tank 1 of the concrete mixing truck.

When the concrete is transported in high-temperature weather in summer, the infrared temperature sensing element 4 fixed in the middle of the water pipe 2 converts the temperature into an electric signal and transmits the electric signal to the PID multi-path controller 10, the PID multi-path controller 10 controls the electromagnetic valve 3 to be opened according to the preset temperature, and the water mist spray head 2 sprays water mist to the surface of the tank body to realize the effect of reducing the temperature of the tank body; the water on the surface of the tank body is collected to a collecting water tank 6 positioned at the bottom of the tank body, when the collecting water tank is full of water, a water level controller 7 positioned on the upper edge of the collecting water tank feeds signals back to a PID multi-path controller 10, the PID multi-path controller 10 controls a water pump 8 to be started according to a preset water level, and the collected water returns to the water tank 1 through a water return pipe 9, so that the water is recycled.
