Description

Technical Field

[0001] The utility model relates to the field of cement culvert processing, in particular to a cement culvert heating and shaping device. Background Art

[0002] Cement culvert heating and shaping equipment, also known as steam curing furnace, usually consists of a relatively closed curing room, which can spray high-temperature steam inside to heat and cure the cement culvert that has entered the initial setting period, thereby accelerating the hardening process of cement and improving its strength. However, in the process of placing the cement culvert into the steam curing furnace to accelerate the curing, placing the cement culvert vertically into the steam curing furnace can reduce the deformation of the cement culvert caused by its own weight, but compared with placing the cement culvert horizontally, the steam flow and temperature distribution effect in the steam curing furnace are slightly inferior, which has an adverse effect on production efficiency. Utility Model Content

[0003] In order to overcome the problem that during the process of placing the cement culvert into the steam curing furnace to accelerate the curing, the cement culvert is placed vertically into the steam curing furnace to reduce the deformation of the cement culvert due to its own weight. However, compared with placing the cement culvert horizontally, the steam flow and temperature distribution in the steam curing furnace are slightly inferior, thereby adversely affecting the production efficiency.

[0004] The technical solution of the utility model is: a cement culvert heating and shaping equipment, comprising a lifting component, a steam curing component, and a gas circulation component; the upper end of the lifting component is provided with a steam curing component for heating and shaping the cement culvert; the upper end of the steam curing component is provided with a gas circulation component for making the gas in the equipment flow to achieve uniform heating and prevent condensation water generated due to excessive saturation of water vapor.

[0005] Preferably, the lifting assembly is used to assist in the placement of the cement culvert, the steam curing assembly is used to heat and shape the cement culvert, and the gas circulation assembly is used to make the gas in the equipment flow to achieve uniform heating and prevent condensation caused by excessive saturation of water vapor.

[0006] Preferably, the lifting assembly includes a base, a hydraulic cylinder, a protective ring, a lifting plate, a first air groove, a cushion block, a docking groove, and a second air groove; three hydraulic cylinders are fixedly connected to the base; the outer sides of the upper ends of the hydraulic cylinders are provided with protective rings fixedly connected to the base; and a lifting plate is provided at the upper end of the base. The upper end surface of the lifting plate is lifted to the same height as the upper end surface of the outer wall by the hydraulic cylinder, and after the cement culvert is placed on the lifting plate, the lifting plate is lowered, and the upper end surface of the cement culvert is made to be the same height as the upper end surface of the outer wall, so that the staff can conveniently place the cement culvert inside the equipment.

[0007] Preferably, a first air groove is provided in the middle of the base; three pads are fixedly connected to the lower end of the lifting plate; docking grooves are provided at the lower ends of the pads; and second air grooves are provided between the three pads. By allowing the protective ring to slide in the docking groove, the hydraulic cylinder is prevented from contacting with hot steam.

[0008] Preferably, the steam maintenance component includes an outer wall, a steam nozzle, an annular air pipe, an air inlet pipe, and a threaded groove; the outer wall is fixedly connected to the upper end surface of the base; and a plurality of steam nozzles are fixedly connected to the outer wall.

[0009] Preferably, the outside of the steam nozzle is connected to an annular air pipe, and the annular air pipe is fixedly connected to the outside of the outer wall, and the front end of the annular air pipe is connected to an air inlet pipe; a threaded groove is provided on the outside of the upper end of the outer wall. Hot steam enters the steam nozzle from the outside through the air inlet pipe and the annular air pipe, so that the steam is evenly sprayed to the outside of the cement culvert.

The exhaust fan allows air to enter the inside of the equipment from the one-way valve, and then the air drives the hot steam on the outside of the cement culvert, and then passes through the second air groove and the first air groove from the lower end of the cement culvert to the inside of the cement culvert in turn, so that the hot steam can maintain the inside of the cement culvert. Finally, the hot steam is discharged from the equipment by the exhaust fan to prevent condensation caused by excessive saturation of water vapor.

[0012] Beneficial effects of the utility model:

[0013] 1. By setting up auxiliary placement mechanism and air circulation mechanism, workers do not need to use lifting equipment to lift the cement culvert to the bottom of the equipment during the placement of the cement culvert, thus avoiding the possibility of the cement culvert being scratched by the heating and shaping device when placing the cement culvert. It can also achieve uniform heating of the cement culvert and prevent the condensed water generated by excessive saturation of water vapor from affecting the normal hydration of cement.

[0014] 2. The upper end surface of the lifting plate is lifted to the same height as the upper end surface of the outer wall by the hydraulic cylinder. After the cement culvert is placed on the lifting plate, the lifting plate is lowered to make the upper end surface of the cement culvert and the upper end surface of the outer wall the same height, so that the staff can place the cement culvert inside the equipment conveniently to avoid the possibility of the cement culvert being scratched by the heating and shaping device when placing the cement culvert;

[0015] 3. After placing the cement culvert, dock the threaded cap at the upper end of the outer wall so that the sealing gasket fits the upper end surface of the cement culvert. Then, the hot steam enters the steam nozzle from the outside through the air inlet pipe and the annular air pipe, so that the steam is evenly sprayed to the outside of the cement culvert. Then, the air is allowed to enter the equipment from the one-way valve through the exhaust fan, and then the air drives the hot steam on the outside of the cement culvert, and successively passes through the second air groove and the first air groove from the lower end of the cement culvert to the inside of the cement culvert, so that the hot steam can maintain the inside of the cement culvert. Finally, the hot steam is discharged from the equipment by the exhaust fan, thereby achieving uniform heating of the cement culvert and preventing the condensed water generated by excessive saturation of water vapor from affecting the normal hydration of cement.

By allowing the protective ring 103 to slide in the docking groove 107, the hydraulic cylinder 102 is prevented from contacting with hot steam.

[0026] See also Figure 4-5 In this embodiment, the steam curing assembly 2 includes an outer wall 201, a steam nozzle 202, an annular air pipe 203, an air inlet pipe 204, and a threaded groove 205; the upper end surface of the base 101 is fixedly connected to the outer wall 201; a plurality of steam nozzles 202 are fixedly connected to the outer wall 201.
