Description

Technical Field

[0001] This application relates to the technical field of boosters, and in particular to a pneumatic booster for conveying slurry in a pipeline. Background Technology

[0002] Currently, during the feeding process of sand mills, liquid and sand are fed together, which can easily clog the feed pipe. In existing technologies, high-pressure water pumps or compressed air are generally used to assist the feeding. However, once the sand blockage is severe, the performance of both methods is unsatisfactory.

[0003] Therefore, there is an urgent need to develop a booster device that has good performance. Utility Model Content

[0004] The purpose of this application is to provide a pneumatic booster for conveying slurry in a pipeline, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this application provides a pneumatic booster for slurry conveying in a pipeline, employing the following technical solution:

[0006] A pneumatic booster for conveying slurry in a pipeline includes a megaphone and a sound wave generator connected to the megaphone. The sound wave generator includes a base, a top cover, a diaphragm, and several steel balls. The base has two concentric outer annular grooves and an inner annular groove. An annular baffle is formed between the inner and outer annular grooves. The height of the annular baffle is lower than the height of the base surface. An air inlet is provided on the side of the base and is connected to the outer annular groove. An air outlet is provided in the middle of the base and is located in the middle of the inner annular groove. Several steel balls are disposed in the inner annular groove. A stepped groove is also provided at the edge of the outer annular groove of the base. The diaphragm is disposed in the stepped groove. The top cover is closed on the base. The diaphragm can move within the stepped groove. The air outlet of the base is connected to one end of the megaphone.

[0007] The amplification tube includes a long tube section, an amplification cavity, and a short tube outlet section that are connected to each other. The sound wave generator is connected to the end of the long tube section, and a flange is installed on the short tube outlet section.

[0008] Preferably, a number of limiting balls are uniformly welded and fixed in the inner annular groove, and a steel ball is placed between adjacent limiting balls.

[0009] By adopting the above technical solution and setting a limiting ball, the steel ball can be limited to avoid multiple steel balls from stacking together. Each steel ball bounces in an independent space, so that it can hit the diaphragm well and make the diaphragm vibrate to produce sound.

[0010] Preferably, in order to ensure a good sealing effect between the base and the top cover, a sealing gasket is provided between the base and the top cover.

[0011] A compressed air intake connector is installed at the air intake port.

[0012] In summary, this application includes at least one of the following beneficial technical effects: the pneumatic booster for conveying slurry in a pipeline is equipped with a sound wave generator. Compressed air is used to blow the diaphragm to vibrate, and the steel balls jump under the influence of the airflow, striking the diaphragm to generate sound waves. After being amplified by the amplifier tube, the sound waves enter the feed pipe with the airflow. When the feed pipe is blocked, the sound waves strike the sand and gravel, causing the sand and gravel to vibrate. Under the blowing of the high-pressure airflow, the vibrating sand and gravel can be easily cleared, resulting in a good boosting effect. Attached Figure Description

[0016] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0017] This application discloses a pneumatic booster for conveying slurry in a pipeline, referring to... Figure 1-2The system includes a megaphone tube 1 and a sound wave generator 2 connected to the megaphone tube 1. The sound wave generator 2 includes a base 21, a top cover 22, a diaphragm 23, and several steel balls 24. The base 21 has two concentric outer annular grooves 25 and an inner annular groove 26. An annular barrier 27 is formed between the inner annular groove 26 and the outer annular groove 25. The height of the annular barrier 27 is lower than the height of the surface of the base 21. An air inlet 211 is provided on the side of the base 21 and is connected to the outer annular groove 25. The air inlet 211 is designed to facilitate the connection of compressed air. A compressed air inlet connector 28 is installed at the base 21. An air outlet 212 is opened in the middle of the base 21. The air outlet 212 is located in the middle of the inner annular groove 26. Several steel balls 24 are arranged in the inner annular groove 26. A stepped groove 213 is also provided at the edge of the outer annular groove 25 of the base 21. A diaphragm 23 is arranged in the stepped groove 213. The top cover 22 is closed on the base 21. A sealing gasket is provided between the base 21 and the top cover 22. The diaphragm 23 can move in the stepped groove 213. The air outlet 212 of the base 21 is connected to one end of the amplifier tube 1.

[0018] Reference Figure 1 The loudspeaker tube 1 includes a long tube section 11, an amplification cavity 12, and a short tube outlet section 13 that are connected to each other. The sound wave generator 2 is connected to the end of the long tube section 11, and a flange is installed on the short tube outlet section 13.

[0019] Reference Figure 2 Several limiting balls 3 are uniformly welded and fixed in the inner annular groove 26, and a steel ball 24 is set between adjacent limiting balls 3.

[0020] By setting a limiting ball 3, the steel ball 24 can be limited, preventing multiple steel balls 24 from stacking together. Each steel ball 24 bounces in an independent space, so that it can hit the diaphragm 23 well, causing the diaphragm 23 to vibrate and produce sound.

[0021] The implementation principle of a pneumatic booster for slurry conveying in a pipeline according to an embodiment of this application is as follows:

[0022] The amplifier tube 1 is connected to the feed pipe of the sand mill via a flange. Compressed air enters the base 21 through the air inlet 211 and exits through the air outlet 212 before entering the feed pipe through the amplifier tube 1, which can achieve basic compressed air propulsion. During this process, the high-pressure airflow can also carry sound waves. When the compressed air enters the base 21, it will blow the diaphragm 23 to shake. At the same time, the steel ball 24 will also collide randomly under the action of the airflow, hitting the diaphragm 23 and generating sound waves. After being amplified by the amplifier tube 1, the sound waves enter the feed pipe with the airflow. When the feed pipe is blocked, the sound waves hit the sand and gravel, causing the sand and gravel to vibrate. The vibrating sand and gravel are easily cleared by the high-pressure airflow.

[0023] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
