Description
Technical Field
The utility model relates to a pneumatics and vacuum technology field, in particular to control energy storage formula energy-conserving vacuum generator that is used for frequent vacuum chuck to adsorb and vacuum destruction.
Background
In various fields, the vacuum adsorption transfer of products is involved, particularly in the occasions of long-time work and frequent adsorption transfer of small products, and the vacuum pump is not suitable for being equipped with a mechanical vacuum pump with higher power. Because the vacuum pump not only consumes large power in these occasions, but also has higher maintenance cost, the long-time operation can greatly shorten the service life of the vacuum pump, and in these occasions, the compressed air is needed to break the vacuum by positive pressure so as to put down or loosen the product.
In some instances where smaller parts are transported by adsorption, some users may use a vacuum generator (vacuum tube) instead of a vacuum pump. However, the vacuum generator applies the working principle of venturi tube (venturi tube), when the compressed air enters from the supply port, the compressed air generates acceleration effect when passing through the narrow nozzle inside, so as to flow through the diffusion chamber at a faster speed, and drives the air in the diffusion chamber to flow out quickly while passing through the diffusion chamber at an accelerated speed, and because the air in the diffusion chamber flows out quickly along with the compressed air, an instant vacuum effect is generated in the diffusion chamber, when the vacuum pipeline is connected to the vacuum suction port, the vacuum generator can pump vacuum to the vacuum pipeline. After the air in the diffusion chamber flows out of the diffusion chamber along with the compressed air and flows through the diffuser, the air pressure flowing out of the exhaust port is rapidly reduced and is blended into the ambient air because the air circulation space is gradually enlarged. And also generally produces loud noise due to the accelerated flow of air out of the exhaust port. In addition, no matter whether the parts are adsorbed or not, the vacuum generator consumes a large amount of compressed air during working, resource waste is obviously caused, and the requirement on a compressed air pipeline is relatively high.

The air inlet front cover 13 is further provided with an air receiving hole 131, and the air inlet front cover 13 is provided with an air exhaust hole 132 for timely exhausting the air flow discharged from the vacuum generator to the outside.
As shown in fig. 2, the vacuum generator assembly 2 includes a vacuum generator fixing seat 21 and a vacuum generator 22, the vacuum generator 22 is arranged on the vacuum generator fixing seat 21 in an array manner, in this embodiment, 5 vacuum generators 22 are adopted, and are arranged on the vacuum generator 22 in an in-line array manner, so that the requirements are met, the consumption of compressed air can be greatly reduced, and the service life of the vacuum generator 22 can be effectively prolonged. Of course, the number of the vacuum generators 22 is not limited to 5, and may be determined according to practical situations, and is not limited herein. Vacuum generator fixing base 21 has the metal product processing to make, wherein is equipped with a recess 211 on vacuum generator fixing base 21 for with the through-hole switch-on the energy storage cavity apron 12, be equipped with the vacuum generator mounting hole on the recess 211, sealing connection between vacuum generator mounting hole and the vacuum generator 22 to prove the leakproofness.
As shown in fig. 2, the control assembly 3 includes: a pneumatic two-position four-way valve 31, a one-way valve 32, a pressure sensor 33 and an intermediate relay 34; the one-way valve 32 is arranged on the inner side of the energy storage cavity 11, is screwed on the energy storage cavity cover plate, and is used for cutting off a passage between the energy storage cavity 11 and the vacuum generator assembly 2 and ensuring the vacuum degree of the inner side of the energy storage cavity 11.

Specifically, external compressed air enters the input end of the pneumatic two-position four-way valve 31 from the air receiving hole 131 of the air inlet front cover plate 13, at this time, because the vacuum pressure value of the inner side of the energy storage cavity 11 is low, the coil of the pneumatic two-position four-way valve 31 is in a ventilation state without being electrified, the compressed air enters the positive pressure pipeline input port on the energy storage cavity cover plate 12 from the output end of the pneumatic two-position four-way valve 31 through the connecting rubber pipe and then enters the positive pressure cavity of the vacuum generator fixing seat 21 through the air flow hole pipeline 121, the positive pressure cavity is communicated with the air inlet of the single vacuum generator 22, as long as compressed air is input, the vacuum generator 22 starts to work and forms vacuum at the vacuum end, and air in the energy storage cavity 11 is pumped out until the vacuum value set on the pressure sensor 33 (adopting. When the vacuum pressure reaches the upper vacuum limit set value, the vacuum negative pressure sensor sends a signal to electrify the intermediate relay 34, so that the coil of the pneumatic two-position four-way valve 31 is electrified, the valve core moves, the air circuit is disconnected, compressed air can not enter the vacuum generator 22, the vacuum generator 22 stops working, and compressed air is not consumed any more. The one-way valve 32 mounted on the energy storage cavity cover plate 12 and located on the energy storage cavity side is closed to prevent air from entering the energy storage cavity in a reverse direction.
When the vacuum in the energy storage cavity 11 is consumed to the lower limit value of the vacuum pressure set by the vacuum negative pressure sensor, the vacuum negative pressure sensor sends a signal to ensure that the intermediate relay 34 is de-energized, the coil energized valve core of the pneumatic two-position four-way valve 31 is reset, the air passage is switched on, and compressed air enters the vacuum generator 22 to ensure that the vacuum generator 22 starts to work until the vacuum degree in the energy storage cavity 11 reaches the upper limit value of the vacuum negative pressure sensor. When the vacuum generator 22 generates vacuum to store energy in the energy storage cavity 11, the vacuum generator 22 consumes energy of compressed air, and the discharged air is discharged to the atmosphere through the soundproof cotton adhered to the air inlet front cover plate 132. When the pneumatic two-position four-way valve 31 is closed and compressed air cannot pass through, the vacuum generator 22 does not consume the energy of the compressed air, and the vacuum consumption element works by means of the vacuum pressure in the energy storage cavity. The energy-storage type energy-saving vacuum generator is the biggest difference between the energy-storage type energy-saving vacuum generator and a common vacuum generator (vacuum tube) during working. The energy-storage type energy-saving vacuum generator structure has short time for supplementing vacuum pressure, can save more than 50% of compressed air consumption, can greatly relieve the pressure of a compressed air pipeline, and saves energy. And because of taking the sound insulation measure, the sound produced by the high-speed air flow is smaller than that of the common vacuum generator when the vacuum generator works.
