A spiral coil machine

Abstract

A spiral coil machine comprises a rack, a main power system, a coil distance adjustment system and a coil auxiliary positioning system. The main power system comprises a motor which is connected with a vertical main axle by two-level speed reduction, the coil positioner is coaxially connected with the upper end of the main axle and extends outside the upper surface of the rack; the coil distance adjustment system comprises a bracket fixed on the rack, a driving gear which is connected with a speed regulation motor is arranged above the bracket and engaged with and drives a driven gear, the driven gear is coaxially connected with a first vertical screw, the first screw is connected with a frame by an axle sleeve, the frame is arranged on the outer side of the bracket and provided with pulleys. The coil auxiliary positioning system comprises a support frame which is fixed on one side of the frame corresponding with the coil positioner, a second horizontal screw is mounted on the support frame and cooperatively provided with a slider, and a top wheel is mounted on one end of the slider corresponding with the coil positioner by a vertical axle. During the pipeline heating process, the automatic degree is high, the size is accurate, one person can produce the coil at high efficiency, and labor and power are saved.

Description

technical field

[0001] The invention relates to a mechanical device, in particular to a spiral coil machine for making small-diameter spiral coils in ascending heat exchange tubes. Background technique

[0002] At present, the rising pipe of coke oven raw gas in the coking industry is transformed and replaced with a rising pipe heat exchanger with a spiral coil device, which absorbs the heat of raw gas to generate saturated steam, which is energy-saving and environmentally friendly, and has a good market prospect.

[0003] Since there are many stainless steel spiral coils in the production of riser heat exchangers, and the ring diameter is small (the diameter of the stainless steel tube is less than 50mm, and the ring diameter of the spiral coil is greater than 200mm), it is not suitable to use the hot simmering process, and manual simmering or The rolling deformation of the plate rolling machine is relatively large, which is not only time-consuming and labor-intensive, but ...
