Being composed of floor plate, tube body, top cover and vent-pipe, the column heat pipe is a seal chamber with vacuum state inside. Capillary cover is in upper part, and floor plate is in lower part of the tube. There is sintered layer on inner wall of tube and inner surface of floor plate. The sintered layer connected to capillary cover constitute closed cycle channel of working fluid, which is adsorbed by the sintered layer and the capillary cover. The column heat pipe is prepared through steps: coating metal powder, and carrying out high sintering so as to form sintered layer; installing capillary cover and top cover; inserting vent-pipe; under special atmosphere furnace, high temperature brazing forms sealed chamber except vent-pipe; filling liquid heat transfer working medium from vent-pipe, and drawing out air; sealing vent-pipe. Features are: quick heat conducting rate caused by evaporation of working liquid and condensed phase change, small thermal resistance and light weight.

The invention discloses a high-efficient propeller curing furnace. The high-efficient propeller curing furnace comprises a furnace body, a fixing shaft, a first material roller, a second material roller, a first supporting shaft, a second supporting shaft, a first supporting belt, a second supporting belt, multiple first mould racks and multiple second mould racks; the first material roller rotates anti-clockwise to reel the first supporting belt; the second material roller rotate clockwise to reel the second supporting belt; the first and second supporting belt separately drive the first supporting shaft and the second supporting shaft to move downwards; the first and second supporting shafts separately drive the multiple first mould racks and the multiple second mould racks to move downwards; the first material roller rotates clockwise to unreel the first supporting belt; the second material roller rotates anti-clockwise to unreel the second supporting belt; the first and second supporting shafts separately move upwards under the effect of a first elastic component and a second elastic component; the upper and lower mould temperature difference of the mould is small; and requirement to the temperature in a moulding process of a composite-material propeller is met.

The invention discloses a household type high-efficiency water heater, which includes a shell, one end of the water inlet pipe is evenly installed inside the copper water tank, and a heating water pipe is evenly installed. The bottom end is connected with a surrounding water pipe, and the surrounding water pipe surrounds the outside of the copper water tank. The outside of the heating water pipe is fixedly sleeved with a driving leaf. Both ends of the copper water tank are welded with U-shaped wind deflectors near the bottom of the driving leaf. An arc-shaped air deflector is installed between two U-shaped air deflectors. Compared with the prior art, the invention has the beneficial effect of ensuring that the temperature of the top and bottom ends of the heating water pipe is consistent during the heating process, reducing the cost of water heating. Time, improve the efficiency of water heating, and absorb the emitted heat, reduce heat consumption, and reduce the energy consumption rate during heating, and reduce the cost of using water heaters.

The invention relates to a steel ladle baking device with a lifting-adjustable ladle cover outer ring. The steel ladle baking device comprises a rack, rotating arms, a ladle cover, heat accumulation type burners and a ladle cover outer ring adjusting device. The two rotating arms are arranged, one ends of the rotating arms are connected to the rack, and the other ends of the rotating arms are connected to the ladle cover. The four heat accumulation type burners are arranged and are symmetrically fixed to the ladle cover. The ladle cover outer ring adjusting device is fixed to the rotating arms and the ladle cover, and the ladle cover outer ring can move vertically so that the distance between the lower end of the ladle cover outer ring and the gap of a ladle opening can be controlled within 200 mm. Injection openings of the heat accumulation type burners incline by a certain angle, so that combustion flames have a certain angle when injected into the steel ladle, the flames flow and rotate around the surface of the ladle wall when impacting the inner wall of the steel ladle to form multiple vortexes, and flowing of hot flue gas is accelerated. By means of the steel ladle baking device, the rotating arms can drive the ladle cover and the burners to move vertically, the ladle cover outer ring moves so that the air inlet amount cannot change, a temperature field in the steel ladle is improved to a certain degree, and the lining temperature in all height directions is more uniform.
