[0002] Pneumatic conveying is a specific application of fluidization technology that uses the energy of airflow to convey powdered materials along the airflow direction in a closed pipeline. The pneumatic conveying system has a simple structure, convenient operation, low maintenance cost, low layout restrictions, can be used for horizontal, vertical or inclined conveying, and has a long conveying distance. It can be loaded in one place and unloaded in multiple places. It is currently widely used in power, chemical, tire, pharmaceutical, food processing, mining and other industries. According to the conveying type of the pneumatic conveying system, it can be divided into dilute phase suspension pneumatic conveying and dense phase pneumatic conveying. The research and application of pneumatic conveying systems have been on dilute phase suspension pneumatic conveying for quite some time. At present, the low-speed dense phase pneumatic conveying technology is becoming more and more mature. With computer control, the pneumatic conveying system has a leap-forward development. In addition, the pneumatic conveying device has a simple structure and is easy to operate. It can be used for horizontal, vertical or inclined conveying. During the conveying process, physical operations such as heating, cooling, drying and airflow classification of materials or certain chemical operations can also be carried out simultaneously.

[0020] (III) Beneficial effects

[0021] Compared with the prior art, the present invention provides a self-inductive constant pressure mining material remote pneumatic conveying system, which has the following beneficial effects:

[0022] 1. When the present invention is in use, materials are transported from the feed pipe into the silo, and the materials are scattered in the shell after being transported by the feed mechanism. The feed mechanism uses the compressed gas in the high-pressure gas storage tank as power to continuously transport the materials in the silo into the shell. At the same time, the Roots blower transports the airflow into the shell through the main air duct to transport the materials, so that the materials are transported in the intermediate pipeline and the conveying pipeline (the conveying pipeline is installed between the two intermediate conduits). The entire conveying process is carried out in a closed pipeline without generating dust. During the conveying process, the booster mechanism installed in the intermediate pipeline can increase the conveying air pressure in the conveying pipeline in the intermediate pipeline, and can promote the deposited materials to merge into the airflow in the conveying pipeline. In this way, the deposited materials can be conveyed by secondary pressurization when conveying materials over long distances, avoiding blockage of the conveying pipeline. At the same time, a retention component is provided on one side of the intermediate pipeline. When discharging is required, the retention component can block the airflow to make the materials quickly deposited and discharged to the material unit with the airflow. The discharging speed is fast and not easy to be blocked.

[0023] 2. The feeding mechanism provided in the present invention, when in use, controls the first electric push rod to reciprocate by controlling the host, and the first electric push rod reciprocates to drive the rectangular tube to make the vertical tube and the capillary tube reciprocate, so that the material in the silo can continuously enter the sleeve, and the first solenoid valve and the second solenoid valve can be opened at the same time, and the compressed gas passes through the first solenoid valve and enters the first annular groove and the second annular groove from the high-pressure pipe and blows the blades, and the blades are driven to rotate the ring and the sleeve after being subjected to force, and the sleeve rotates to drive the spoiler teeth to stir the falling material. At this time, the falling materials can be broken up, and at the same time, the gas is discharged into the shell through the conduit after being discharged, and the air pressure in the shell is increased to transport the materials. The compressed gas enters the high-pressure hose and the riser through the second solenoid valve, and a part of the compressed gas in the riser is discharged from multiple capillaries through the rectangular tube, and the other part of the gas is blown toward the materials from the inclined nozzle through the gas distribution head. At this time, the materials can smoothly enter the shell from the sleeve, and when the first electric push rod is in a retracted state, the flow limiting block installed under the gas distribution head can block the materials from entering the sleeve.

[0024] 3. The present invention is provided with a conveying mechanism. When in use, the compressed gas generated by the Roots blower enters the shell through the main air duct, and the airflow flows into the main pipe through two branch pipes. When the airflow in the main pipe is discharged, it can drive the material in the horizontal pipe to move, and then the first motor is started to drive the first worm to rotate the horizontal axis. The rotation of the horizontal axis drives the blades to promote the airflow, so that the material is further blown away and enters the horizontal pipe to be transported. When the first worm rotates, it drives the first worm wheel to rotate the rotating shaft. The rotation of the rotating shaft drives the second worm to rotate the second worm wheel. The rotation of the second worm wheel drives the supporting shaft to make the rocker arm perform a circular motion. When the rocker arm performs a circular motion, the pin drives the frame to swing the aeration pipe. When the aeration pipe swings, the compressed gas input from the conduit and the soft pipe is discharged through the aeration holes on the aeration pipe. At this time, the compressed airflow can be used to blow up the material falling on the bending plate to avoid the accumulation of materials in the shell and causing blockage.

[0025] 4. The boosting mechanism provided in the present invention, when in use, starts the second motor to drive the first bevel gear to rotate the second bevel gear and the third bevel gear, the second bevel gear rotates to drive the main shaft to rotate the second spoiler, the third bevel gear rotates to drive the sleeve to rotate the first spoiler, and the rotation directions of the first spoiler and the second spoiler are opposite, at this time, the first spoiler and the second spoiler can be used to mechanically boost and convey the material, and when the fourth solenoid valve is opened, the compressed gas enters from the auxiliary air pipe and the air pipe joint and is finally discharged from the through hole on the main shaft, and the discharged compressed gas is tilted to the material in the middle pipe, so that the material can be conveyed in a gas boosting manner, when discharging is required, the second electric push rod is started to extend the valve core into the middle pipe, at this time, the material in the middle pipe and part of the airflow are intercepted and enter the discharge pipe, and finally the airflow and the material are discharged from the elbow to the material unit, when discharging is not required, the valve core moves down to the lower point to block the pipe mouth of the elbow, so that the material and the airflow cannot be discharged to stop discharging.

When the aeration pipe 28 swings, the compressed gas input from the conduit 23 and the soft pipe is discharged through the aeration holes on the aeration pipe 28. At this time, the compressed airflow can be used to blow up the material falling on the bending plate 27 to avoid the accumulation of materials in the housing 1 and blockage.

[0054] A through hole is opened through the center of the main shaft 53, and two flow velocity sensors are fixedly connected to the wall of the intermediate pipe 7. The two flow velocity sensors are respectively located on both sides of the connection between the casing 4 and the intermediate pipe 7. The airflow velocity sensor and the first pressure gauge are fixedly connected to the wall of the intermediate pipe 7.

[0055] The interception assembly includes a valve core 54, which is sleeved in a discharge pipe 6. The lower end of the discharge pipe 6 is fixedly connected to a second electric push rod 5. The output end of the second electric push rod 5 is fixedly connected to the lower end of the valve core 54 through a bracket. The upper end of the valve core 54 is provided with an arc-shaped extension portion. A discharge hole is penetrated through the side wall of the valve core 54, and a bent pipe is fixedly connected to the wall of the discharge pipe 6.

[0056] The booster mechanism provided in the present invention, when in use, starts the second motor 3 to drive the first bevel gear 51 to rotate the second bevel gear 52 and the third bevel gear 50, the second bevel gear 52 rotates to drive the main shaft 53 to rotate the second spoiler 47, the third bevel gear 50 rotates to drive the sleeve 49 to rotate the first spoiler 48, and the first spoiler 48 and the second spoiler 47 rotate in opposite directions, at this time, the first spoiler 48 and the second spoiler 47 can be used to mechanically boost and convey the material, and when the fourth solenoid valve 8 is opened, the compressed gas is connected to the auxiliary air pipe 9 and the air pipe. The compressed gas enters the middle pipe 7 and is finally discharged from the through hole on the main shaft 53. The discharged compressed gas is obliquely blown toward the material in the middle pipe 7, so that the material can be transported in a gas pressurized manner. When discharging is required, the second electric push rod 5 is started to make the valve core 54 extend into the middle pipe 7. At this time, the material in the middle pipe 7 and part of the airflow are intercepted and enter the discharge pipe 6. Finally, the airflow and material are discharged from the elbow to the material unit. When discharging is not needed, the valve core 54 moves down to the lower point to seal the pipe mouth of the elbow, so that the material and airflow cannot be discharged to stop discharging.
