[0019] Example:
[0020] As attached Figure 1 As shown, a long-distance pneumatic conveying stabilization device includes a material drop bucket 1, a material drop pipe 2 is fixed at the lower part of the material drop bucket 1, and is characterized in that a material drop amount controller 3 is installed at the lower part of the material drop amount controller 3, a flange connecting pipe 4 is arranged at the lower part of the material drop amount controller 3, a drop observation connector 5 is installed at the lower part of the flange connecting pipe 4, a Roots blower connecting pipe 6 is connected to the left side of the drop observation connector 5, and a feeding pipe 7 is connected to the right side of the drop observation connector 5; the material drop amount controller 3 includes a mounting shell 31, a mounting groove 32 is opened at the rear end of the lower inner side of the mounting shell 31, a compound threaded adjustment rod 33 is arranged on the inner side of the mounting groove 32, an adjustment knob 34 is fixed to the right side of the compound threaded adjustment rod 33, a connecting rod threaded hole slider 35 is arranged on the left and right sides of the front end of the compound threaded adjustment rod 33, and an opening and closing pouring plate 36 is symmetrically arranged on the left and right sides of the interior of the mounting shell 31.
[0021] As attached Figure 3 As shown, in the above embodiment, specifically, the drop material observation connector 5 comprises a hollow pipe 51, and connecting flanges 52 are respectively integrated on the left and right sides of the outside of the hollow pipe 51, an inclined end feeding pipe 53 is welded on the upper part of the hollow pipe 51, and transparent observation windows 54 are respectively embedded in the front and rear ends of the inner side of the hollow pipe 51.
[0022] In the above embodiment, specifically, the connecting rod threaded hole sliders 35 are respectively threadedly connected to the left and right sides of the exterior of the compound threaded adjustment rod 33 , and the connecting rod threaded hole sliders 35 are inserted into the inner side of the installation groove 32 .
[0023] In the above embodiment, specifically, a limiting connecting rod is integrally provided at the front end of the connecting rod threaded hole slider 35 , and the limiting connecting rod is tightly fitted on the lower part of the opening and closing pouring plate 36 .
[0024] In the above embodiment, specifically, the upper portion of the inclined end feed pipe 53 is bolted to the lower portion of the flange connection pipe 4, and the lower portion of the inclined end feed pipe 53 is inclined toward the lower right portion.
[0025] In the above embodiment, specifically, the Roots blower connecting pipe 6 and the feeding pipe 7 are bolted to the left and right sides of the hollow pipe 51 respectively, and scale lines are engraved on the surface of the transparent observation window 54.
[0026] How it works
[0027] The working principle of the utility model is as follows: the feeding structure on the upper part of the material drop bucket 1 conveys the material downward through the material drop bucket 1, and then the material falls downward through the drop pipe 2 and the flange connection pipe 4, and the airflow from the external Roots blower outlet flows from left to right inside the hollow pipe 51 through the Roots blower connection pipe 6, so that a negative pressure is formed inside the inclined end feed pipe 53, and suction is generated on the falling material. After the material falls to the inside of the hollow pipe 51 through the inclined end feed pipe 53, it is quickly blown away by the airflow and then conveyed to the storage bin through the feeding pipe 7. The staff observes the falling situation inside the hollow pipe 51 through the transparent observation window 54, and The amount of material falling is determined by the scale lines engraved on the surface of the transparent observation window 54. When the position of the material after falling is at the bottom of the scale line, it means that the amount of material falling is large. At this time, the staff can rotate the compound threaded adjustment rod 33 by adjusting the knob 34. The compound threaded adjustment rod 33 drives the connecting rod threaded hole sliders 35 on the left and right sides to move closer to the middle. The connecting rod threaded hole sliders 35 drive the lower parts of the opening and closing pouring plates 36 to move closer to each other, reducing the opening size of the lower inner part of the opening and closing pouring plates 36, thereby reducing the amount of material falling. When the position of the material after falling is at the upper part of the scale line, it means that the amount of material falling is small. The falling amount can be appropriately increased to improve the conveying efficiency.
[0028] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the protection scope of the utility model.
