Description

Technical Field

[0001] The invention relates to the technical field of concrete component curing devices, and in particular to a precast concrete component heating and curing device. Background Art

[0002] Prefabricated concrete parts are called PC components in the field of residential industrialization. Such as prefabricated reinforced concrete column foundation, prefabricated steel structure steel column foundation, street light billboard column reinforced concrete foundation, prefabricated floor slab. The corresponding traditional cast-in-place concrete requires on-site molding, on-site pouring and on-site maintenance. Prefabricated concrete parts are widely used in construction, transportation, water conservancy and other fields, and play an important role in the national economy. Nowadays, when prefabricated concrete components are maintained in winter, PC components often need to be placed in maintenance equipment for maintenance. In the maintenance of components, heating maintenance is usually adopted, mostly steam heating.

[0003] An existing precast concrete component heating and curing device (Announcement No.: CN222431092U) has at least the following disadvantages: the above patent can place the component to be cured between two heat-conducting plates through the coordinated arrangement of a curing box, a door panel, a fixing seat, a plurality of heat-conducting plates, a heating tube and a heating element in an outer protective box, so that the surface of the component can be heated as a whole, thereby avoiding the situation where the upper and lower surfaces of the component are heated unevenly; because when steam is used to heat and cure the concrete component, the temperature in the curing box will continue to rise. When the temperature in the curing box is too high, the cement particles cannot be completely hydrated, thereby affecting the final quality and strength of the overall concrete component. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a precast concrete component heating and curing device.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A precast concrete component heating and curing device comprises a curing box, a curing frame is installed inside the curing box, a sealing door is hinged on the outer surface of the curing box, an evaporation box is fixedly installed on the bottom of the curing box, a plurality of air outlets connected to the evaporation box are evenly penetrated through the bottom of the curing box, a water storage tank connected to the evaporation box is fixedly installed on the outer surface of one side of the curing box, a temperature sensor is fixedly installed on the top wall of the curing box, an electric heating plate is fixedly installed on the bottom wall of the evaporation box, an exhaust pipe is fixedly installed on the outer surface of the curing box near the top thereof, one end of the exhaust pipe away from the curing box is inserted into the water storage tank, and a cooling mechanism is installed on the top of the curing box.

[0007] In this embodiment, the cooling mechanism includes a plurality of spray pipes, and a plurality of spray heads connected to the interior thereof are fixedly installed on the outer surfaces of the plurality of spray pipes, and the spray heads are arranged through the top of the curing box, and water outlet pipes are fixedly installed between the plurality of spray pipes. A piston tube is fixedly installed on the top of the water storage tank, and the water outlet pipe is connected to the interior of the piston tube. A water inlet pipe connected to each other is fixedly installed between the piston tube and the water storage tank, and one-way valves with opposite conduction directions are respectively installed on the water inlet pipe and the water outlet pipe.

[0008] In this embodiment, an energy storage mechanism is installed on the top of the water tank, and the energy storage mechanism includes a gas bottle fixedly installed on the top of the water tank, the bottom of the gas bottle is connected to the interior of the water tank, the top of the gas bottle is fixedly installed with a pressure relief valve connected to the interior, and the top of the gas bottle is fixedly installed with an air outlet pipe connected to the interior, and the air outlet pipe is respectively installed with a driving component and a conducting component.

[0009] In this embodiment, the driving assembly includes a drum fixedly mounted on the air outlet pipe, the drum and the air outlet pipe are connected to each other, an impeller is rotatably mounted inside the drum, a turntable is fixedly mounted at the rotation center of the impeller, and a liquid pumping assembly is installed between the turntable and the piston tube.

[0010] In this embodiment, the pumping assembly includes a rotating rod rotatably mounted on the outer surface of the turntable, and a movable plug that can move up and down is installed on the inner wall of the piston tube. The end of the rotating rod away from the turntable is rotatably mounted on the top of the movable plug.

[0012] In this embodiment, an electromagnet is fixedly mounted on the lower surface of the mounting plate, and an iron block is fixedly mounted on the top end of the sealing plug.

[0013] In this embodiment, two limit plates are symmetrically fixedly installed on the inner wall of the evaporation box on the side close to the water storage tank, and a floating block is slidably installed between the two limit plates and the inner wall of the evaporation box.

[0014] The beneficial effects of the present invention are:

[0015] 1.

The cement particles cannot be completely hydrated due to the excessively high curing temperature, thereby affecting the overall final quality and strength of the concrete components;

[0016] 2. After the water level in the evaporator tank drops, the floating block arranged in the evaporator tank moves down accordingly, so that the floating block connects the water storage tank and the evaporator tank, allowing the water in the water storage tank to enter the evaporator tank, thereby realizing the automatic addition of water in the evaporator tank; after the water level in the evaporator tank rises, the floating block moves up to cut off the connection between the water storage tank and the evaporator tank, thereby preventing all the water in the water storage tank from flowing into the evaporator tank, which increases the energy consumption required for heating by the electric heating plate.

[0038] When the temperature sensor 7 installed on the top wall of the curing box 1 detects that the temperature inside the curing box 1 is too high, the temperature sensor 7 will disconnect the power supply of the electric heating plate 8 through the external controller to stop the generation of steam, and at the same time turn on the electromagnet 25, so that the electromagnet 25 attracts the sealing plug 23 upward through the iron block 26, so that the conducting hole 24 opened on the sealing plug 23 is connected to the air outlet pipe 15, so that the gas with a certain pressure stored in the gas storage bottle 9 can enter the drum 17 through the air outlet pipe 15, so that the flowing gas can blow the impeller 18 to rotate, so that the impeller 18 drives the turntable 19 rotates, so that the rotating turntable 19 can drive the movable plug 14 to perform piston movement in the piston tube 11 through the rotating rod 20, so that the water in the water storage tank 4 can be sucked into the piston tube 11 through the water inlet pipe 12, and then the movable plug 14 presses the water in the piston tube 11 into the multiple spray pipes 27 through the water outlet pipe 13, and then the multiple spray heads 28 spray the water on the surface of the concrete component inside the curing box 1 to cool it down, so as to prevent the concrete component from being unable to be completely hydrated due to the excessively high curing temperature, thereby affecting the final quality and strength of the entire concrete component.
