Description

Technical Field

[0001] This utility model relates to the field of pneumatic conveying technology, specifically an adjustable airflow amplifier. Background Technology

[0002] In the field of solid material conveying, Roots blowers are commonly used as the power source for dilute phase conveying. However, in some factories, only air compressors, such as screw compressors, are used as the instrument air source for the entire plant. To save costs, air compressors are needed to complete pipeline dilute phase conveying. However, because pipeline dilute phase conveying requires a relatively high air volume and a relatively low pipeline conveying pressure, while air compressors can output higher pressures but lower air volumes, it is inevitable to increase the load and power consumption of the air compressor in order to obtain a higher output air volume for dilute phase conveying. Utility Model Content

[0003] To address the problem of increased load and power consumption caused by air compressors in order to obtain higher output air volume, this invention provides an adjustable airflow amplifier for use with air compressors.

[0021] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Reference Figure 1 As shown, the adjustable airflow amplifier in this embodiment includes: a flow guide pipe 1, a high-pressure airflow pipe 3, an airflow ejector pipe 4, a jet pipe 5, a servo electric cylinder 7, and an airflow diffuser 8.

[0023] The guide pipe 1 is provided with a guide sleeve seat 2 inside. The guide sleeve seat 2 divides the inner cavity of the guide pipe 1 into a high-pressure airflow chamber 100 and a mixed airflow chamber 101. Two sets of pipe interfaces 102 are provided on the side wall of the guide pipe 1, which are respectively connected to the high-pressure airflow chamber 100 and the mixed airflow chamber 101.

[0024] The high-pressure airflow pipeline 3 is connected to the pipeline interface 102 that communicates with the high-pressure airflow chamber 100. The high-pressure airflow pipeline 3 is equipped with a pressure regulating valve 11, a temperature transmitter 12, and a pressure transmitter 13, which can respectively regulate the pressure, detect the temperature, and detect the pressure of the high-pressure airflow.

[0025] The airflow ejector duct 4 is connected to the pipe interface 102 that communicates with the mixing airflow chamber 101. The airflow ejector duct 4 is equipped with a filter 14 and a wind speed transmitter 15, which can filter the introduced air and measure the wind speed respectively.

[0026] The jet pipe 5 penetrates the inner ring of the guide sleeve seat 2. An air inlet 500 is provided on the side wall of the main body located in the high-pressure airflow chamber 100, and a nozzle 6 is provided at its end located in the mixing airflow chamber 101.

[0027] The servo electric cylinder 7 is located at the end of the guide pipe 1 adjacent to the high-pressure airflow chamber 100. The piston rod of the servo electric cylinder 7 extends into the high-pressure airflow chamber 100 and is connected to the adjacent end of the jet pipe 5.

[0028] The airflow diffuser 8 is connected to the end of the guide pipe 1 adjacent to the mixing airflow chamber 101.

[0029] High-pressure airflow from the air compressor is introduced through the high-pressure airflow pipe 3 and then guided into the high-pressure airflow chamber 100 of the guide pipe 1. The high-pressure airflow enters through the inlet 500 on the jet pipe 5 and then exits through the nozzle 6 at the end of the jet pipe 5, entering the mixing airflow chamber 101 of the guide pipe 1. Due to the high velocity of the high-pressure airflow, the airflow ejector pipe 4 can draw in atmospheric air and guide it into the mixing airflow chamber 101 using the principle of an ejector, thus increasing the air volume in the mixing airflow chamber 101. The gas in the mixing airflow chamber 101 is then discharged from the airflow diffuser 8. The gas discharged from the airflow diffuser 8 can serve as a power source for the pipeline dilute phase transport of solid materials. Therefore, it can be seen that a higher output air volume can be obtained for dilute phase transport without increasing the load and power consumption of the air compressor. The distance between the nozzle 6 and the airflow diffuser 8 can be changed by moving the jet pipe 5 driven by the servo electric cylinder 7. As the distance between the nozzle 6 and the airflow diffuser 8 changes, the gas velocity and pressure output by the airflow diffuser 8 will also change. The closer the distance between the nozzle 6 and the airflow diffuser 8, the greater the gas velocity output by the airflow diffuser 8, but the smaller the gas volume. Conversely, the farther the distance between the nozzle 6 and the airflow diffuser 8, the smaller the gas velocity output by the airflow diffuser 8, but the larger the gas volume. This achieves adjustable dilute phase transport gas volume.

[0030] In this embodiment, the guide pipe 1 is also provided with a first sealing ring 9 and a second sealing ring 10 that respectively seal and cooperate with the outer wall of the jet pipe 5 and the outer wall of the piston rod of the servo electric cylinder 7. The first sealing ring 9 and the second sealing ring 10 are both used to prevent high-pressure gas leakage in the high-pressure airflow chamber 100.

[0031] In this embodiment, the port of the internal channel of the airflow diffuser 8 adjacent to the guide pipe 1 is a tapered opening with a gradually narrowing diameter, so that the gas in the mixing airflow chamber 101 can enter the internal channel of the airflow diffuser 8. The port of the internal channel of the airflow diffuser 8 away from the guide pipe 1 is a tapered opening with a gradually widening diameter, so that the kinetic energy of the gas entering the internal channel of the airflow diffuser 8 can be converted into pressure for the dilute phase transport of solid materials through the pipeline.

[0032] The embodiments of the present invention described above do not constitute a limitation on the scope of protection of the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
