TECHNICAL FIELD

[0001] The utility model relates to the technical field of concrete curing, in particular to a device for simulating constant air temperature to cure concrete test blocks. BACKGROUND

[0002] Water bath heating equipment requires a high initial investment, and the operation and maintenance costs are also relatively high. This increases the overall cost of concrete test block curing. Although water bath heating can provide certain temperature control, it is difficult to completely simulate the complex environment of project site construction curing. Especially when considering factors such as humidity, air pressure, etc., the limitations of water bath heating are more obvious. In order to overcome the limitations of water bath heating, the current trend of technological development is to develop new curing devices. These devices can more accurately control the curing environment, including temperature, humidity, etc., thereby better simulating the on-site construction curing environment. New curing devices not only focus on cost control, but also pay attention to improving curing efficiency and quality. By optimizing curing parameters and processes, the curing cycle can be shortened, and the strength and durability of the concrete test block can be improved. With the development of science and technology, intelligent and automated technologies are also increasingly widely used in the field of concrete test block curing. By introducing intelligent devices such as sensors and control systems, real-time monitoring and accurate control of the curing environment can be achieved, improving the accuracy and reliability of the curing. Therefore, it is necessary to design a device for simulating constant air temperature to cure concrete test blocks to solve the above problems under the premise of ensuring efficiency. SUMMARY

[0003] The utility model aims at providing a device for simulating constant air temperature to cure concrete test blocks to solve the problems raised in the background art.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical scheme:

[0005] A device for simulating constant air temperature to cure concrete test blocks, comprising:

[0006] A fan heater is provided with two air inlets and an air outlet, and a carrying strap is also provided on the fan heater.

[0007] A model box is provided with a temperature insulation cover and a temperature controller.

[0008] A heat insulation pipe is connected to one end of the air outlet and the other end of the temperature insulation cover.

[0009] The air return pipe has one end connected to the air inlet and the other end connected to the model box. The heat insulation pipe sends the hot air blown out by the heater into the model box and returns it to the heater for reuse through the air return pipe. The thermostat is used to keep the temperature in the model box constant and to keep the concrete test block placed in the model box warm.

[0010] Preferably, the model box is further provided with a lifting component, which includes a lifting telescopic rod disposed in the model box and a lifting plate disposed on the lifting telescopic rod.

[0011] Preferably, the lifting telescopic rod is used to move the lifting plate, thereby causing the concrete test block placed on the lifting plate to extend or retract into the model box.

[0012] Preferably, the heat insulation cover is further provided with a heat equalization component, which includes a heat equalization ring disposed on the heat insulation cover, a jet plate sleeved on the heat equalization ring, a nozzle disposed on the jet plate, a distribution pipe disposed on the heat insulation cover and communicating with the heat insulation pipe, a ventilation hose disposed on the distribution pipe and communicating with the jet plate, a push plate and a reset plate disposed on the jet plate, a heat equalization telescopic rod disposed on the heat equalization ring and connected to the push plate, and a reset spring disposed on the heat equalization ring and connected to the reset plate.

[0013] Preferably, the air distribution duct is used to receive the hot air supplied by the heat insulation pipe and send it into the jet plate, from which it is ejected from the nozzle. The heat equalization telescopic rod is used to drive the jet plate to move along the heat equalization ring, thereby changing the jet position of the nozzle.

[0014] Preferably, the heat insulation cover is provided with a handle and a sealing ring.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention, through the setting of a warm air blower and a temperature controller, can approximately simulate the curing environment of concrete under most constant air temperatures. It can simultaneously perform curing at multiple different temperatures, is easy to operate, and has low cost. By setting up several nozzles, hot air is evenly dispersed and blown onto the concrete specimen, so that the concrete specimen is heated uniformly. By setting up a heat-uniforming telescopic rod and a return spring, the spray position of the nozzles can be changed to avoid a certain point of the concrete specimen being constantly heated to an excessively high temperature.
