Description

Technical Field

[0001] The invention relates to the technical field of spiral fin tube auxiliary processing equipment, and in particular to a high-speed steel belt toothing machine used for toothing fins of a spiral fin tube. Background Art

[0002] In recent years, environmental protection and energy conservation have become important directions for the structural adjustment of China's power industry. Under the policy orientation of "promoting large and suppressing small", the thermal power industry has actively promoted the optimization and upgrading of the industrial structure, shutting down a large number of small thermal power units with low energy efficiency and heavy pollution, which has greatly accelerated the replacement of domestic thermal power equipment and boosted the market demand for thermal power equipment. At present, the localization rate of manufacturing of ultra-supercritical 1 million kilowatt thermal power units in my country has reached 100%, and the localization rate of materials has reached more than 90%. By the end of 2008, 11 sets of 1 million kilowatt ultra-supercritical units had been put into commercial operation. Compared with supercritical 600,000 kilowatt units, they save about 550,000 tons of standard coal each year, making a huge contribution to the optimization of thermal power structure, energy conservation and emission reduction in my country's power industry. The large-scale thermal power projects have brought development opportunities for high-end thermal power equipment, and large-scale thermal power equipment such as supercritical steam turbine units have become the focus of development.

[0003] In thermal power generating units, boiler efficiency is an important indicator of the economic operation of the unit. Among all types of boiler heat losses, exhaust heat loss accounts for more than half of the total boiler heat loss [1]. Research results show that for every 30°C increase in exhaust temperature, boiler efficiency decreases by 1% and the unit standard coal consumption increases by 3g / (kW˙h) [2]. The exhaust temperature design value of the current units is about 130°C, but due to coal-fired conditions and power plant operation levels, the actual exhaust temperature is generally around 150°C. Higher exhaust temperatures will lead to lower boiler efficiency, higher annual average coal consumption of the unit, and increased smoke pollutant emissions, affecting the economic operation of the unit and pollutant emission indicators. Therefore, how to effectively recycle exhaust waste heat has become an urgent problem to be solved by thermal power generating units.

[0004] At present, low-temperature economizer technology and low-temperature flue gas treatment technology are the main technologies for flue gas waste heat recovery, and the main heat exchange element is the spiral fin tube. The spiral fin tube is a high-efficiency heat exchange element. Its structure mainly includes: a heat exchange tube, and fins arranged on the outer wall of the heat exchange tube along the axial spiral. The fins are generally made of steel strips. Spiral fin tubes are widely used in various heat exchange equipment. They can not only enhance heat transfer, but also reduce flow resistance, and have relatively high thermal efficiency. Since the application of spiral fin tubes in production practice, people have been discussing its optimal design. A lot of research has been conducted on the geometric dimensions of the fin tubes-wing height, wing pitch, wing thickness and the arrangement of the fin tube bundle to further improve the thermal efficiency. The structural optimization of spiral fin tubes involves many factors. These factors influence and restrict each other, making the structural optimization problem of the spiral fin tube bundle very complicated, with nonlinear and multivariable characteristics. According to research, the spiral fin tube with a toothed structure of fins is the optimal structure, which can not only increase the heat exchange area of ​​the tube bundle, but also reduce the resistance characteristics and reduce ash blockage. Therefore, it is urgent to invent a device that can quickly tooth the steel strip. Summary of the invention

[0026] The working principle of the present invention is as follows:

[0027] First, place the steel strip coil on the discharge tray 14, and then manually pull one end of the steel strip coil through the material strip running buffer 33, the feed flexible guide pressure wheel 16 of the material guide mechanism and the feed flexible guide top wheel 17 to between the lower positioning tooth opening die 4 and the upper positioning guide pressure plate 5 of the tooth opening positioning module, and then start the reduction motor 10 to make the rotating shaft 7 drive each cutter head 9 to complete the tooth opening of the end of the steel strip coil, and then manually pull the end of the steel strip coil with the tooth opening completed to between the belt feeding flexible stop wheel 28 and the belt pulling rigid gear 29 of the servo pulling mechanism, so that the gear teeth of the belt pulling rigid gear 29 fit into the tooth grooves of the toothed steel strip;

[0029] Press the start button to start the reduction motor 10.

When each cutter head 9 rotates with the rotating shaft 7, it will pass through the tooth opening positioning module one by one and open the teeth of the steel belt in the tooth opening positioning module; when all the cutter heads 9 have just rotated through the tooth opening positioning module and completed the tooth opening action of the steel belt in the tooth opening positioning module, each cutter head 9 will continue to rotate with the rotating shaft 7 and pass the proximity switch 31. The main shaft rotates 1 / 3 of a circle for tooth opening, and the remaining 2 / 3 of a circle of the main shaft is idling; when idling, the proximity switch 31 senses and detects the cutter head 9, and at this time the proximity switch 31 will send a material pulling signal to the PLC controller. After receiving the material pulling signal, the PLC controller will control the material pulling servo motor 30 and the material receiving motor 22 to operate. After the material pulling servo motor 30 pulls the toothed steel strip out of the toothing positioning module through the pulling belt rigid gear 29 and pulls a new section of the steel strip to be toothed into the toothing positioning module, the material pulling servo motor 30 stops operating. At the same time, after the material receiving motor 22 drives the receiving tray 20 to rotate and rewind the toothed steel strip, the material receiving motor 22 stops operating. After the material pulling servo motor 30 pulls a new section of the steel strip to be toothed into the toothing positioning module, each cutter head 9 rotates one circle with the rotating shaft 7 to open the teeth of the new section of the steel strip to be toothed that enters the toothing positioning module. This high-speed cycle is continued to achieve rapid tooth opening of the steel strip.

[0030] The invention has the advantages that the teeth of the steel strip can be opened quickly and the tooth opening efficiency is high.
