Description

Low temperature temperature difference sealing circulating type motor

What the utility model low temperature temperature difference sealing circulating type motor related to is a kind of power take-off of utilizing solar energy and waste gas residual heat to carry out the hot merit converting system.

At present, the power system that the whole world is used is still based on high-temperature heat engine, in consuming a large amount of energy fuels, has 60% heat energy to be dumped, and has caused energy crisis, and environmental pollution is serious, and this has become one of human urgent problem.

The purpose of this utility model is that the hot merit converting system deficiency at above-mentioned high-temperature heat engine provides a kind of low temperature temperature difference sealing circulating type motor, with a kind of simpler and more direct, economical and practical structural type, reach the heat under the low temperature situation---merit conversion purpose.

The purpose of this utility model is achieved in that low temperature temperature difference sealing circulating type motor, have heat collector, vaporizer, reflux pump, condenser, storage battery, inverter, generator, automatic adjusting color controls, be connected with mechanism in the sealed enclosure, form sealed circulation system.Engine body is a cylindrical shape, eccentric shaft, rotor cover are housed in the casing inner cylindrical cylinder, have radial groove on the cylinder, a slide plate that has the top spring is installed in the groove, the slide plate both sides have port to lead to outside the casing, and casing sealing gland and shaft sealing device are equipped with in the casing two ends.

The simple and direct practicality of low temperature temperature difference sealing circulating type engine structure, applied widely, this machine operating temperature is lower, in 40-80 ℃ of temperature range, to the more numerous sense of thermal source, therefore can be used as the spcific power equipment that solar energy utilizes the hot merit converting system of aspect, for alleviating city dweller's power supply, tall building is powered, and solving areas without electricity household electricity problem has certain effect.Also can be used as the special engine that waste gas residual heats such as utilizing the internal-combustion engine boiler carries out the auxiliary power combination, thereby improve the effect of existing heat engine system effectively, reach energy-saving and cost-reducing, reduce and pollute, improve energy utilization rate.This machine is under the sealing cycling condition, adopts low boiling liquid refrigerant and thermal-arrest---the supporting running of condenser system, produces high-pressure gaseous working medium by heat collector absorption heat energy and carries out heat---the merit conversion.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a fundamental diagram of the present utility model.

Fig. 2 is low temperature temperature difference sealing circulating type motor embodiment's a longitudinal section tectonic maps.

Aa among the figure, heat collector Bb, condenser Cc, reflux pump Dd, vaporizer E1E2, two-way switch G, drive wheel H, the generator electric motor I of holding concurrently, inverter J, storage battery K, controller L, gas-liquid separator M, working medium exchanging pump W, motor 1, casing 2, cylinder 3, eccentric wheel rotating shaft 4, rotor sleeve 5, inlet hole 6, exhaust port 7, radial groove 8, slide plate 9, spring 10, output shaft A, hyperbaric chamber B, the middle chamber of pressing.

In Fig. 1, open controller switches (K), by storage battery (J), inverter (1), actuating motor (generator hold concurrently) (H) are started working when system all starts, and electric functions transfers electricity generate function to.Under the effect of sunlight heat or other thermal source, heat collector (A) (a) is heated and produces high-pressure gaseous working medium, through entering motor (W) cylinder to high pressure gas pipeline in, gas-liquid separator (L) rectifying carries out work, gas after the acting is transported to (b) middle condensation of condenser (B) by exhaust duct, gaseous working medium through condenser is reduced into liquid refrigerant because of heat release, by reflow pipe be passed to sealed type reflux pump (C) (c) in, through pressurization be pushed into vaporizer (D) (d) in atomizing enter heat collector (A) and (a) circulate once more.Circular flow constantly and produce power output thus, drive supporting power plant, as drive wheel (G) and generator (H).Because of being two cover circulatory systems in the design, when not having solar irradiation, control two-way switch device (E1, E2) automatically by controller (K) and close first cover system, start exchange working medium pump (M) exchange, when exchange finishes, open second cover system automatically and turn round.Because the work cycle of this machine is carried out in whole sealing status, therefore the useful horsepower of motor (W) be by working medium heat collector (A) (a) and the difference of the temperature of condenser (B) between (b) determined that promptly the inlet pressure of motor (W) and outlet pressure is poor.

In embodiment illustrated in fig. 2, cylindrical cylinder (2) is arranged in the cylindrical casing (1), one of central position assembling has eccentric rotating shaft (3) in the cylinder, on eccentric wheel, be with a rotary sleeve (4) and form rotor, rotor is around rotating center 0, under high-pressure gaseous working medium promotes, being docile and obedient clockwise rolls on the internal surface of cylinder (2), both have a contact straight line is the tangent line of two cylindrical surface, roll and form circumference changeable crescent-shaped space one by one a week, the two ends of cylinder form cylinder working chamber by the cylinder head sealing.On casing (1), be provided with high pressure admission hole (5) and middle pressure pore (6), have a radial groove (7) between two holes, a radially slide plate (8) is housed in the groove, spring (9) is equipped with at the top, top end is close to rotor surface all the time in the slide plate, crescent-shaped space is divided into two parts, a part is connected with inlet hole (5) becomes air inlet hyperbaric chamber (A), another part is connected with exhaust port (6) becomes middle pressure air cavity (B), promote the rotor rolling when the cycle of higher pressure gaseous working medium enters hyperbaric chamber, rotor coaxial rotary output axis (10) drives generator (H) work.
