Description

Technical Field

[0001] The utility model relates to the technical field of mold temperature controllers, in particular to a high-efficiency, energy-saving and environmentally friendly gas mold temperature controller. Background Art

[0002] The mold temperature controller, also known as the mold temperature controller, was originally used in the temperature control industry of injection molds. Later, with the development of the machinery industry, it was used more and more widely and was widely used in various industries such as plastic molding, die casting, rubber tires, rollers, chemical reactors, bonding, and mixing. Nowadays, the mold temperature controller is generally divided into water temperature controller and oil temperature controller, which usually includes temperature control of heating and freezing.

[0003] At present, in the relevant technology, the mold temperature controller uses heat transfer oil as heat medium and natural gas as energy. The heat generated by the combustion of natural gas is used to heat the heat transfer oil, and the heated heat transfer oil is used to exchange heat with external equipment. In this process, the combustion of natural gas will produce high-temperature flue gas. If the high-temperature flue gas is not utilized, the energy loss will increase. The existing gas-fired mold temperature controller is not convenient for recycling the heat in the high-temperature flue gas generated by the combustion of gas. In view of this, we propose a high-efficiency, energy-saving and environmentally friendly gas-fired mold temperature controller. Utility Model Content

[0007] The heat exchange assembly includes a central axis with both ends fixedly connected to the inner wall of the oil storage cylinder, a spiral heat exchange plate is fixedly arranged on the outer edge surface of the central axis, a plurality of groups of spiral heat exchange tubes are coaxially arranged in the spiral heat exchange plate, a connecting pipe connected to the spiral heat exchange tube is centrally arranged in the central axis, one end of the connecting pipe extends through one end of the oil storage cylinder and is connected to a flue gas pipe, the end of the flue gas pipe away from the connecting pipe is connected to the combustion chamber, and the other end of the connecting pipe is connected to a smoke exhaust pipe extending out of the oil storage cylinder.

[0008] Preferably, the oil circuit structure includes an oil outlet pipe with one end connected to the oil storage tank from the bottom of the outer edge of the oil storage cylinder, and the end of the oil outlet pipe away from the oil storage cylinder is connected to the second flange plate.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. By setting up a heat exchange component, when the combustion cylinder burns gas to heat the heat transfer oil in the heating cylinder, the high-temperature flue gas generated can enter the heat exchange component through the flue gas pipe. Since the heat exchange component is located in the oil storage tank, the high-temperature flue gas can exchange heat with the heat transfer oil in the oil storage tank after entering the heat exchange component, thereby preheating the heat transfer oil in the oil storage tank, making it convenient to recycle the heat in the high-temperature flue gas, which is beneficial to reducing the loss of gas energy and achieving the purpose of high efficiency, energy saving and environmental protection.

By designing the spiral heat exchange plate and the spiral heat exchange tube into a spiral shape, and providing multiple groups of spiral heat exchange tubes, the high-temperature flue gas can enter the connecting tube through the flue pipe, and enter the multiple groups of spiral heat exchange tubes through the connecting tube. The provision of multiple groups of spiral heat exchange tubes is conducive to ensuring that the heat transfer oil in different axial and radial areas in the oil storage tank can be fully exchanged with heat, and by providing the spiral heat exchange tube in the spiral heat exchange plate, the spiral structure of the spiral heat exchange plate is conducive to increasing the heat exchange area with the heat transfer oil, thereby improving the heat exchange effect and realizing full utilization of the heat in the high-temperature flue gas.
