Abstract

The utility model relates to a cylinder exhaust recovery energy-saving control device, which comprises an air source, a throttling valve, a cylinder, a pressure switch, a reversing valve, a differential pressure switch, a check valve, a recovery gas tank and the like. When the differential pressure of the upstream and the downstream of the differential pressure switch (7) is less than 0.05MPa, compressed air of an exhaust cavity of a cylinder (3) is recovered to the gas tank (9) through a reversing valve (6), a solenoid valve (10) and a check valve (8); and when the differential pressure of the upstream and the downstream of the differential pressure switch (7) is larger than or equal to 0.05MPa, a reversing valve (10) is controlled to reverse, a left position of the reversing valve (10) is switched on, and the compressed air of the exhaust cavity of the cylinder (3) is exhausted to the atmosphere through the reversing valve (10) so as to realize the switching of exhaust recovery. Compared with the prior art, the device recovers the compressed air of the exhaust cavity of the cylinder as much as possible, and has small influence on kinetic characteristics of the cylinder; and when the exhaust is recovered, the system exhaust recovery rate can reach more than 70%, which indicates that the recovery system not only has an obvious energy-saving effect but also has a good application prospect.

Description

Cylinder exhaust gas recovery energy-saving control device
(1) technical field
The utility model relates to mechanical transmission, field of energy-saving technology, specifically is the power-saving technology in a kind of pneumatic actuator system.
(2) background technique
In modernized country, since use pressurized air as the pneumatic system of working medium have energy-conservation, pollution-free, efficient, low-cost, structure is simple relatively, safe and reliable, can be used for inflammable and explosive and advantage such as radiation risk occasion is arranged, and be widely used in every profession and trade, especially industrial automation field, be the important means of enhancing productivity in each industrial department, the important effect of play more and more in the development of the national economy.Yet, as most widely used executive component---cylinder in the pneumatic system, after it finished a working stroke, the general direct row of pressurized air in the former active chamber of cylinder was to atmosphere, concerning the manufacturing mechanism of long-term operation, caused very big energy loss.We are example with modern mechanical enterprise, and in its energy consumption ratio, compressed-air actuated use accounts for 20% of whole energy consumption, and wherein the exhaust of cylinder reciprocating action has accounted for 12% of integral body.Therefore, cylinder exhaust gas recovery Research on Saving Energy has great energy-saving significance and engineering using value.
(3) summary of the invention
The utility model sets out based on the energy-conservation thought that the portion of energy of utilizing the accumulation of energy gas tank to reclaim the inblock cylinder air cavity is done work again, a kind of new energy-conservation thinking of cylinder exhaust gas recovery has been proposed, promptly the pressurized air of inblock cylinder air cavity is concentrated recovery by exhaust recovery device is set, when gas holder pressure reaches desired pressure value, reclaim gas tank as in the pressure air source utilize again.This energy conserving system can realize that not only the inblock cylinder air cavity has the recovery of the body of calming the anger, and the pressurized air that is recovered in the gas tank can directly be used in pneumatic system without any processing.
The technological scheme that its technical problem that solves the utility model adopts is: cylinder exhaust gas recovery energy-saving control device, comprise compressed gas source (1), one-way throttle valve (2), cylinder (3), pressure switch (4), selector valve (5), it is characterized in that: 1, comprise the recovery switching control, this device is made up of two electric control reversing valves (6), differential pressure switch (7), one-way valve (8), recovery gas tank (9) and single electric control reversing valve (10).2, when differential pressure switch (7) upstream and downstream pressure difference signal during less than 0.05MPa, flow through two electric control reversing valves (6), single electric control reversing valve (10) and one-way valve (8) of cylinder (3) exhaust cavity pressurized air is recycled to gas tank (9); When differential pressure switch (7) upstream and downstream pressure difference signal during more than or equal to 0.05MPa, control single electric control reversing valve (10) commutation, position, single electric control reversing valve (10) left side is connected, and cylinder (3) exhaust cavity pressurized air to atmosphere, is realized the switching of exhaust gas recovery through single electric control reversing valve (10) row.
The utility model compared with prior art can be to the recovery as much as possible of inblock cylinder air cavity pressurized air, and is less to the cylinder moving properties influence again; During exhaust gas recovery, the system exhaust reuse efficiency can reach more than 70%; This shows this reclaiming system, and not only energy-saving effect is remarkable, and has a good application prospect.
(4) description of drawings
Fig. 1 is a fundamental diagram of the present utility model.
(5) embodiment
As shown in Figure 1, known cylinder (3) upstream pressure p 1, reclaim gas tank (9) downstream pressure p 2And differential pressure switch (7) the pressure differential deltap P that passes through the setting of Regulation spring handle SwDuring work, differential pressure switch (7) is detected pressures difference Δ p=p in real time 1-p 2, when pressure difference Δ p reaches set pressure differential Δ P SwDuring=0.05MPa, differential pressure switch (7) sends electrical signal, the switching of control electromagnetic valve (10).
As shown in Figure 1 under the state, cylinder (3) exhaust cavity links to each other with differential pressure switch (7) upstream tube road junction, reclaiming gas tank (9) links to each other with differential pressure switch (7) downstream tube road junction, when magnetic switch (4) when sending signal, solenoid valve (6) switches to right position, if pressure difference Δ p is greater than setting up exhaust gas recovery switching controls pressure differential deltap P between cylinder (3) exhaust cavity and recovery gas tank (9) SwThe time, differential pressure switch (7) output electrical signal is connected the right position of solenoid valve (10), flow through throttle valve (2), selector valve (5), solenoid valve (6) and solenoid valve (10), one-way valve (8) of the pressurized air of cylinder (3) exhaust cavity arranged to gas tank (9), thereby realization exhaust gas recovery, increase gradually along with reclaiming gas in the gas tank (9), gas tank (9) internal pressure is more and more higher, and pressure difference is more and more littler between cylinder (3) exhaust cavity and gas tank (9), reaches or less than setting up pressure differential deltap P until Δ p SwThe time, differential pressure switch (7) stops to export electrical signal, and at this moment solenoid valve (10) resets, and cylinder (3) exhaust cavity residual gas is arranged to atmosphere.Thereby realized the switching controls of cylinder exhaust callback course.
The utility model not only can be realized the real-time switching of cylinder exhaust gas recovery control procedure, and control accuracy is higher, and easy to operate, reliability is better.Calculate by the actual measurement to the reuse efficiency of exhaust recovery system, the system exhaust reuse efficiency can reach more than 70% during exhaust gas recovery, and this shows this reclaiming system, and not only energy-saving effect is remarkable, and has a good application prospect.
