Description
Technical Field
The invention relates to the field of processing and forming of pit heat transfer pipes, in particular to an automatic feeding device for a pit heat transfer pipe production line.
Background
Heat transfer is a very common natural phenomenon, a common process in industries such as power, nuclear, electronics, traffic, refrigeration, chemical, petroleum, aerospace, and the like. The heat exchanger plays a key role in the industries, and the heat exchanger not only is an indispensable component for ensuring the normal operation of the whole engineering equipment, but also plays an important part in the whole engineering in the aspects of metal consumption, power consumption, capital investment and the like. Taking a power plant as an example, if a boiler is also used as heat exchange equipment, the capital investment of the heat exchanger accounts for about 70% of the total investment of the power plant; in petrochemical industry, the investment of a heat exchanger is 50% of the total investment; in addition, due to the fact that non-renewable resources such as coal, petroleum, natural gas and the like are reduced day by day in the world, the energy utilization rate of the heat exchanger is improved, and energy waste is reduced. Therefore, the reasonable design of the heat exchanger is very important for saving resources and reducing the material consumption of metal materials. The heat exchange performance of the heat transfer pipe has a decisive effect on the heat exchange performance of the heat exchanger and is a core working element of the heat exchanger, so that the heat energy utilization rate of the heat exchanger can be greatly improved by improving the heat exchange performance of the heat exchange pipe, and the consumption of resources and metal materials is reduced. In order to improve the performance of the heat exchange tube, an enhanced heat transfer technology is often adopted; the so-called intensified heat transfer technology is to strive for more heat transferred by the heat exchanger per unit time and per unit area. Existing enhanced heat transfer techniques include the development of various types of enhanced heat transfer tubes, such as zoom tubes, bellows, spiral grooved tubes, and other types of enhanced heat transfer tubes. The pit heat transfer pipe is a high-efficiency heat transfer pipe which is recently developed at home and abroad and has a plurality of characteristics.
The pit heat transfer pipe as a novel high-efficiency reinforced heat transfer pipe has the following characteristics: 1) when fluid flows through the pit pipe section, due to the separation effect of the boundary layer, the fluid forms a transverse vortex behind the pit, once the vortex is formed, the vortex moves towards the center of the pipe and is gradually enlarged to form a vortex, the vortex increases the mixing operation of the fluid in the boundary layer, and the heat transfer coefficient can be greatly improved; 2) due to the scaling and scouring action of the pit heat transfer pipe, the anti-fouling performance of the inside and the outside of the pipe is excellent; 3) the heat transfer pipe of the pit has stronger thermal stress resistance than that of a common light pipe due to the action of the pit; 4) due to the arrangement form of pits of the pit pipe, the fluid pressure loss can be reduced, and a low-power pump can be selected; 5) the pit heat transfer pipe increases the heat transfer area and enhances the turbulent flow of fluid due to the action of the pits. Therefore, under the condition of the same heat exchange amount, the pit heat transfer pipe can reduce the occupied space volume of the heat exchanger and reduce the weight.
In recent years, many devices for machining and manufacturing pit heat transfer tubes are publicly known in China, such as: a stamping type industrial high-efficiency tube forming table with a patent number of CN2017106146693, a multi-cylinder type T-cell heat transfer tube extrusion forming device with a patent number of CN2017106146640, an interlaced T-cell heat transfer tube extrusion forming device with a patent number of CN201710614666X and a wedge type T-cell heat transfer tube extrusion forming device with a patent number of CN 201710614658.5.
In addition, in recent years, many domestic devices for extruding a pitted pipe are disclosed, such as: a stamping type industrial high-efficiency tube forming table with a patent number of CN2017106146693, a multi-cylinder type T-cell heat transfer tube extrusion forming device with a patent number of CN2017106146640, an interlaced T-cell heat transfer tube extrusion forming device with a patent number of CN201710614666X and a wedge type T-cell heat transfer tube extrusion forming device with a patent number of CN 201710614658.5.
However, although there are many types of pit heat transfer tubes processing and manufacturing devices, manual tube feeding and tube unloading are required during pit tube production and processing, which results in low automation degree of pit tube production line and high pit tube production and manufacturing cost.
