Description

Technical Field

[0001] This utility model relates to the field of heating furnace technology, and in particular to an active cooling temperature adjustable heating furnace. Background Technology

[0002] With the development of technology in the metallurgical industry, heating furnaces are devices that heat materials or workpieces to rolling or forging temperatures. Their structure and working principle can vary depending on the type of heating furnace, but the basic principle is similar. They mainly include a preheating section, a heating section, and a soaking section. The main function of the preheating section is to preheat the materials or workpieces entering the heating furnace, reducing the energy consumption of the entire heating process. Heat is usually transferred through radiation and convection to avoid quality problems caused by uneven temperature. In the production and manufacturing of optical fibers, high-temperature heating is required to melt the preform and draw it into optical fibers.

[0003] Existing heating furnace equipment mainly consists of a shell and heating wires. The material is placed inside the shell and heated at a constant temperature using the heating wires.

[0004] The current shell has poor cooling performance and a long natural cooling time, which affects subsequent processing and use. Utility Model Content

[0005] The purpose of this invention is to provide an active cooling temperature adjustable heating furnace, which aims to solve the problems of poor shell cooling effect and long natural cooling time, which affect subsequent processing and use.

The heat dissipation unit includes an outer shell, a heat dissipation chamber, a base plate, a hydraulic cylinder, a copper ring, multiple heat-absorbing plates, a water inlet pipe, a water outlet pipe, and a connecting seat. The heating wire is disposed on the inner wall of the shell, the heat dissipation unit is disposed on the outer wall of the shell, and the installation unit is disposed on the inner wall of the shell. The outer shell is fixedly connected to the shell and located on the outer wall of the shell. The base plate is slidably connected to the outer shell and located on the inner wall of the shell. The heat dissipation chamber is fixedly connected to the base plate and located above the base plate. The copper ring is fixedly connected to the heat dissipation chamber and located on the inner wall of the heat dissipation chamber. The copper ring is slidably adapted to the housing. The heat dissipation chamber has multiple strip-shaped holes, each of which is adapted to a corresponding heat absorption plate. The heat absorption plates are all fixedly connected to the copper ring and are located on the outer side wall of the copper ring. The water inlet pipe is connected to the heat dissipation chamber and is located on the outer side wall of the heat dissipation chamber. The water outlet pipe is connected to the heat dissipation chamber and is located on the outer side wall of the heat dissipation chamber. The outer shell has symmetrical sliding holes, which are slidably engaged with the water inlet pipe and the water outlet pipe, respectively. The connecting seat is fixedly connected to the base plate and is located below the base plate. The hydraulic cylinder is fixedly connected to the outer shell and is located on the inner bottom wall of the outer shell. The output end of the hydraulic cylinder is fixedly connected to the connecting seat and is located below the connecting seat.

[0007] The heat dissipation unit further includes a fixing frame and a sliding shaft. The fixing frame is fixedly connected to the outer shell and located on the inner top wall of the outer shell. The sliding shaft is fixedly connected to the base plate and located above the base plate, and the sliding shaft is slidably engaged with the fixing frame.

[0008] The heat dissipation unit further includes a first docking ring and a second docking ring. The first docking ring is fixedly connected to the water inlet pipe and is located on the outer wall of the water inlet pipe.

The heat insulation plate is fixedly connected to the housing and located above the housing, and the heat insulation plate is in contact with the heating wire. The mounting bracket is detachably connected to the housing and located above the housing. The locking bolt passes through the mounting bracket and the housing in sequence.

[0011] This utility model discloses an active cooling temperature-adjustable heating furnace. In use, the water inlet pipe needs to be connected to an external water source. The hydraulic cylinder is activated to move the base plate upwards. At this time, the copper ring contacts the shell, and heat is transferred from the heat absorption plate to the heat absorption chamber. The external water source absorbs the heat and discharges it through the water outlet pipe, which can quickly cool the furnace. In this way, the cooling time of the shell is reduced, ensuring the subsequent processing and use of the shell and reducing the workload of the workers. Attached Figure Description
