Preferably, the bottom position of the baffle in the vertical state is slightly higher than the spout center position of the nozzle.
The beneficial effects of the invention are mainly represented in the following aspects:
(1) The air pressure detection device on the branch pipeline adopts the vacuum gauge and the pressure gauge, the vacuum gauge and the pressure gauge are connected with the controller, and pressure values detected by the vacuum gauge and the pressure gauge can be fed back to the controller during working. The system can be automatically operated and closed under the unattended condition easily through the simple two meters, so that the air compressor can be prevented from working invalidity under the premise of ensuring that the work is not influenced, and the energy consumption is reduced.
According to the invention, the rotatable and swinging baffle plate is arranged at the outer side of the nozzle end of the nozzle, when the air compressor works normally, the baffle plate is impacted by high-speed air flowing through the nozzle to be in an inclined state, when the air utilization equipment end stops using air, the swinging angle of the baffle plate is detected to be zero by the angle sensor for measuring the swinging angle of the baffle plate at the moment, the swinging angle of the baffle plate is gradually reduced as the air flow rate of the air at the nozzle is continuously reduced, the swinging inclined amplitude of the baffle plate is gradually reduced (the included angle between the inclined state and the initial vertical state is gradually reduced), the spring force of the spring is preset, and when the spring force of the spring to the baffle plate is larger than the impact force of the air to the baffle plate, the baffle plate is quickly restored to the initial vertical state, and the swinging angle of the baffle plate is detected to be zero by the angle sensor for measuring the swinging angle of the baffle plate at the moment, and the controller is used for transmitting a signal for closing the air compressor, so that the energy-saving work of the air compressor is further ensured, and the energy consumption is reduced.
The invention makes double measures for avoiding the air compressor from working inefficiently, and the air compressor can independently exist, thereby reducing the possibility of failure of energy-saving work.
(2) In the invention, the branch pipeline is provided with the electromagnetic valve which is connected with the controller. When the air compressor works normally, the electromagnetic valve is opened, high-speed air is formed by high-pressure air from the air compressor through the nozzle, the air pressure in the main pipeline is reduced, so that air outside the pipeline is sucked into the main pipeline through the branch pipeline, the flow rate of the air is increased, and the conversion from a smaller rated conveying amount to a larger actual conveying amount is realized.
From the above, the invention has the advantages of more reasonable and sufficient utilization of gas, reduced waste, reduced cost, reduced energy consumption, simple structure and reliable and stable operation.
(3) The electromagnetic valve is arranged in the main gas transmission pipeline between the air compressor and the nozzle and close to the nozzle, so that the air pressure detection device can feed back in time when the air pressure in the pipeline is reduced by using air for air equipment, and adverse factors caused by poor tightness of the air inlet end in the main gas transmission pipeline are effectively avoided, thereby reducing the air leakage quantity in the air pressure detection area in the pipeline and maximally preventing the air compressor from working invalidively due to self leakage of air.
(4) In the invention, the nozzle is positioned at one end of the main pipeline of the air transmission close to the air compressor. Through the design, the air from the air compressor is smaller in flow velocity loss when passing through the nozzle, so that the flow of air sucked from the outside of the pipeline is increased, and the distance is shorter when the air is connected with a vacuum gauge, a pressure gauge, an angle sensor and an electromagnetic valve, so that the operation is convenient.
(5) The nozzle is in a reduced diameter shape, and the size of the nozzle end is smaller. Through the design, the high-pressure air can smoothly pass through the nozzle, the excessive loss of the gas flow rate is avoided, the gas has high speed after passing through the nozzle, and the suction force of the air outside the pipeline is larger.
(6) The central axis of the branch pipeline and the gas transmission direction of the main gas transmission pipeline form an obtuse angle, and the angle range is 130-170 degrees. By adopting the design, the gas flow directions in the main pipeline and the branch pipeline are more consistent, and a good foundation is laid for the gas outside the pipeline to smoothly flow into the main pipeline.
(7) The bottom position of the baffle plate in the vertical state is designed to be slightly higher than the central position of the nozzle, so that the blocking of the baffle plate to the gas flow rate in the main gas pipeline is reduced as much as possible on the premise of forming a swing angle, the smooth circulation of high-pressure air is ensured, and useless consumption is avoided.

As shown in fig. 1, the bottom position of the baffle 13 in the vertical state is slightly higher than the center position of the nozzle 11.
The working principle of the invention is described in detail below with reference to examples:
1) When the air using equipment needs to use air, the air compressor 20 starts to work (at the moment, the electromagnetic valve 50 on the branch pipeline 12 is in a normally closed state, the electromagnetic valve 50 on the main air pipeline 10 is in a normally open state), high-pressure air passes through the nozzle 11 to form high-speed air, the baffle 13 is in an inclined state under the impact of the high-speed air and forms a certain included angle alpha (shown in fig. 2) with the initial vertical state, and the elastic device 60 has a pulling force on the baffle 13, but the pulling force is smaller than the impact force of the high-speed air on the baffle 13; in addition, under the action of the high-speed air, the air in the branch pipeline 12 is sucked into the main air conveying pipeline 10, the vacuum gauge 41 detects a negative pressure value, when the air pressure in the branch pipeline 12 is reduced to the negative pressure a, the pressure value a is fed back to the controller 30, the controller 30 transmits an opening signal to the electromagnetic valve 50 on the branch pipeline 12, the electromagnetic valve 50 on the branch pipeline 12 is opened accordingly, and a large amount of air outside the pipeline is sucked into the main air conveying pipeline 10 through the branch pipeline 12.
2) When the gas using equipment finishes using gas, the air compressor 20 keeps working, the air in the main gas transmission pipeline 10 is gradually increased, the air flow rate at the nozzle 11 is gradually reduced, the gas pressure in the main gas transmission pipeline 10 is increased, the gas pressure in the branch pipeline 12 is also increased, when the gas pressure in the branch pipeline 12 is increased to negative pressure b, the pressure value b is fed back to the controller 30, the controller 30 transmits a closing signal to the electromagnetic valve 50 on the branch pipeline 12, and the electromagnetic valve 50 is closed; after the electromagnetic valve 50 on the branch pipeline 12 is closed, the air pressure in the pipeline is continuously increased, the air flow rate at the nozzle 11 is continuously reduced, on one hand, the impact force of flowing air on the baffle 13 is continuously reduced, so that the swing slant amplitude of the baffle 13 is gradually reduced (the included angle alpha between the slant state and the initial vertical state is gradually reduced), the elastic force of the elastic device 60 (spring) is preset, when the impact force of flowing air on the baffle 13 is smaller than the pull force of the elastic device 60 on the baffle 13, the baffle 13 is quickly restored to the initial vertical state (shown in fig. 1), at the moment, the angle measuring device 70 (angle sensor) detects that the swing angle of the baffle 13 is zero and feeds back the angle value to the controller 30, the controller 30 transmits a closing signal to the air compressor 20, and the air compressor 20 is closed accordingly; on the other hand, the pressure gauge 42 detects a positive pressure value, when the impact force of the flowing gas on the baffle 13 is smaller than the critical point of the tension of the elastic device 60 on the baffle 13, the pressure of the gas in the branch pipeline 12 is increased to a positive pressure c, at this time, the pressure value c is fed back to the controller 30, the controller 30 transmits a signal for closing the electromagnetic valve 50 on the air compressor 20 and the main gas pipeline 10, and then the air compressor 20 is closed, and the electromagnetic valve 50 on the main gas pipeline 10 is closed. In the invention, the elastic force of the elastic device 60 (spring) is preset, and when the pressure of the gas in the branch pipeline 12 is increased to positive pressure c, the tension of the elastic device 60 on the baffle 13 is larger than the impact force of flowing gas on the baffle 13; the two technical schemes for ensuring the energy-saving operation of the air compressor 20 are in parallel operation, and the two technical schemes can independently exist, so that the adverse phenomenon that the energy-saving control of the air compressor 20 fails is effectively reduced or even stopped through the double-insurance design.
3) When the gas using device is used again, the gas in the pipeline flows outwards, the gas pressure is reduced, when the gas pressure in the branch pipeline 12 is reduced to positive pressure d, the pressure value d is fed back to the controller 30, the controller 30 transmits a signal for opening the electromagnetic valve 50 on the air compressor 20 and the main gas pipeline 10, the electromagnetic valve 50 on the main gas pipeline 10 is opened, and the air compressor 20 starts to work.
After the operation of the air compressor 20, the operation is continued according to the principle (1) described above.
The pressures a and b related to the working principle are negative pressures, and the value b is larger than the value a; the pressures c and d are positive pressure, and the value of c is larger than the value of d.
