Description

Technical Field

[0001] This invention relates to the field of coal washing machine technology, specifically to a device for intelligently adjusting the air volume and air pressure of a jigging coal washing machine. Background Technology

[0002] The jigging coal washing machine, also known as the air-pulsating jig, is one of the most widely used gravity separation equipment in coal preparation plants. Its core function is to use air-driven vertical pulsating water flow to achieve the separation of clean coal, middlings, and gangue in raw coal according to density. The existing jigging coal washing machine relies on manual operation for air volume and air pressure adjustment, which requires a high level of skill from the operators. This makes it easy for human factors to affect the instability of sorting accuracy and the recovery rate of clean coal during adjustment, so improvements are needed. Therefore, it is necessary to invent a device for intelligently adjusting the air volume and air pressure of a jigging coal washing machine. Summary of the Invention

[0004] To achieve the above objectives, the present invention provides the following technical solution: a device for intelligently adjusting the air volume and air pressure of a jigging coal washing machine, comprising a cabinet, a Roots blower, an air valve, an air inlet pipe one, and an air inlet pipe two; The Roots blower is fixedly connected to the top of the cabinet. The first air inlet pipe, the air valve, and the second air inlet pipe are fixedly connected in sequence. The end of the first air inlet pipe is fixedly connected to the air outlet of the Roots blower. The cabinet door is equipped with a controller, the cabinet is equipped with a servo motor, the servo motor is equipped with a drive component between the valve stem of the air valve, and the cabinet side is equipped with a flow sensor and a pressure sensor.

[0005] Furthermore, the Roots blower, servo motor, flow sensor, and pressure sensor are all electrically connected to the controller.

[0006] Furthermore, the controller integrates a touch screen.

[0007] Furthermore, the drive component includes a U-shaped frame, which is fixedly connected to the inner wall of one side of the cabinet, and a servo motor is fixedly connected to the bottom of the U-shaped frame. The output shaft of the servo motor is fixedly connected to a threaded rod, which passes through the U-shaped frame.

[0008] Furthermore, a threaded block is sleeved on the outside of the threaded rod, and the threaded block is connected to the threaded rod by threads. A protruding rod is fixedly connected to one side of the threaded block.

[0018] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0019] Example: See attached document Figure 1 - Appendix Figure 5 The present invention provides a device for intelligently adjusting the air volume and air pressure of a jigging coal washing machine, comprising a cabinet 1, a Roots blower 2, an air valve 3, an air inlet pipe 4 and an air inlet pipe 5; The Roots blower 2 is fixedly connected to the top of the cabinet 1. The air inlet pipe 4, the air valve 3, and the air inlet pipe 5 are fixedly connected in sequence, and adjacent pipes are connected by flanges and bolts. The end of the air inlet pipe 4 is fixedly connected to the air outlet of the Roots blower 2, and the two are also connected by flanges and bolts (bolts are not shown in the diagram). A controller 6 is installed on the door of cabinet 1, and the controller 6 integrates a touch screen. A servo motor 7 is installed inside cabinet 1, and a drive component is installed between the servo motor 7 and the valve stem of the air valve 3. A flow sensor 8 and a pressure sensor 9 are installed on the side of cabinet 1, and both the flow sensor 8 and the pressure sensor 9 can be installed on the second air intake pipe. Figure 1 and 4 As shown, it can also be set inside the coal washing machine, depending on the situation. In order to connect the controller 6 to all components, the Roots blower 2, servo motor 7, flow sensor 8 and pressure sensor 9 are all electrically connected to the controller 6. When in use, the end of the second air inlet pipe 5 can be connected to the air inlet of the coal washing machine using flanges and bolts. Then, air can be supplied to the coal washing machine during the sorting process. When supplying air, the Roots blower 2 is controlled to work. Then, under the action of the first air inlet pipe 4, the air valve 3, and the second air inlet pipe 5, air can be supplied to the coal washing machine. When supplying air, the controller 6 collects air volume and air pressure data in real time through the flow sensor 8 and pressure sensor 9 in the air inlet pipe 2 5. At the same time, the controller 6 has pre-stored the optimal air volume and air pressure parameters corresponding to different coal types. When the actual data fed back by the flow sensor 8 and the pressure sensor 9 deviates from the pre-stored parameters, the controller 6 will automatically analyze the deviation. For example, if the raw coal particle size becomes coarser and the air pressure needs to be increased, the controller 6 can control the servo motor 7 to work. Then, under the action of the drive component, the valve stem of the air valve 3 will be driven to increase the opening and closing range of the air valve 3. At the same time, the controller 6 can also adjust the operating frequency of the Roots blower 2 to match the air volume demand. Subsequently, through the continuous feedback of data from the sensors, the controller 6 continuously corrects the instructions to achieve dynamic adaptation of air volume, air pressure and raw coal characteristics. The same applies to reducing air volume and air pressure, which will not be described in detail here. The entire process described above can be monitored in real time via a touchscreen and parameters can be adjusted with a single click, achieving unmanned and precise control. In this embodiment, the driving component includes a U-shaped frame 10, which is fixedly connected to the inner wall of one side of the cabinet 1. The servo motor 7 is fixedly connected to the bottom of the U-shaped frame 10. The output shaft of the servo motor 7 is fixedly connected to a threaded rod 11, which passes through the U-shaped frame 10. A threaded block 12 is sleeved on the outside of the threaded rod 11. The threaded block 12 and the threaded rod 11 are connected by threads. A protruding rod 13 is fixedly connected to one side of the threaded block 12. A connecting rod 14 is provided on one side of the threaded block 12. A sliding groove is provided on the connecting rod 14, and the protruding rod 13 passes through the sliding groove and slides in contact with it. A rotating shaft 15 is fixedly connected between the connecting rod 14 and the valve stem of the air valve 3, and the rotating shaft 15 is embedded in one side of the cabinet 1. It should be noted that when the servo motor 7 is working, it can rotate the threaded rod 11. The rotation of the threaded rod 11 drives the threaded block 12 to move upward, which in turn causes the convex rod 13 to move upward. Since the convex rod 13 passes through the sliding groove on the connecting rod 14, when the convex rod 13 moves upward, it can cause the convex rod 13 and the rotating shaft 15 to rotate around the rotating shaft 15 as the rotation axis. This allows the valve stem of the air valve 3 to rotate, thereby adjusting the opening and closing range of the air valve 3. When the adjustment needs to be smaller, it is only necessary to control the servo motor 7 to rotate in the opposite direction. In addition, the threaded block 12 and the threaded rod 11 are connected by threads, similar to the threaded connection between a bolt and a nut. Moreover, the threaded connection is a self-locking structure. This prevents the threaded block 12 from moving up and down arbitrarily when the air is flowing and comes into contact with the valve plate in the air valve 3, thereby preventing changes in the opening and closing range. In this embodiment, a limiting rod 16 is fixedly connected to the U-shaped frame 10. The limiting rod 16 passes through the threaded block 12 and slides in contact with it. The limiting rod 16 can limit the threaded block 12, thereby making the threaded block 12 move up and down stably. In this embodiment, the threaded rod 11 is connected to the U-shaped frame 10 by a bearing, and the rotating shaft 15 is connected to the cabinet 1 by a bearing. The bearing connection can reduce the wear caused by rotation. In this embodiment, support legs 17 are fixedly connected to the four corners of the bottom of the cabinet 1, and the support legs 17 can support the entire device. In this invention, the model specifications of the controller 6, Roots blower 2, air valve 3, servo motor 7, flow sensor 8 and pressure sensor 9 need to be selected and determined according to the actual specifications of the entire device. Moreover, the above-mentioned components are very mature products in the prior art, so the specific model specifications will not be described in detail. Secondly, the control method of the present invention is automatic control through controller 6. The control circuit of controller 6 can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, the present invention is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail in the present invention. Finally, it is readily apparent that all content not described in detail in this specification, except as described above, is prior art known to those skilled in the art.

[0020] The above are merely preferred embodiments of the present invention. Any person skilled in the art can modify the present invention or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of the present invention fall within the scope of protection claimed by the present invention.
