Description

Technical Field

[0001] This utility model relates to the field of silo equipment technology, specifically to a conical discharge valve for discharging materials from a silo. Background Technology

[0002] According to the Chinese utility model patent with publication number CN217599420U, entitled "A Conical Feeding Valve for Automatic Discharge of a Mobile Silo", the lifting mechanism can effectively lift the conical spinning part, which rises and falls within the mobile silo, thereby controlling the gap between the spinning part and the pipe outlet. The powder is discharged from the silo along the inner wall of the pipe and the edge of the spinning part. Relying solely on the gap between the conical valve and the pipe wall to regulate the flow rate can easily lead to material impact and flow rate fluctuations at high flow rates, making it difficult to achieve precise graded control. Therefore, we propose a conical feeding valve for silo discharge. Utility Model Content

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] See attached document Figure 1-5In this embodiment, a conical discharge valve for discharging materials from a silo is provided, including a pipe 1 and a conical valve 3 that slides along the axial direction of the pipe 1. A sealing ring 13 is also provided on the inner wall of the pipe 1, distributed radially thereon. The sealing ring 13 is used to limit the position of the conical valve 3. When the conical valve 3 contacts the sealing ring 13, the material in the pipe 1 is subjected to gravity, causing the conical valve 3 to press against the sealing ring 13. This limits the position and also blocks the gap between the pipe 1 and the sealing ring 13. When the conical valve 3 is lifted upwards, a groove 14 opened along the path on the sealing ring 13 will allow the material falling onto the sealing ring 13 to fall off the groove 14, preventing material accumulation on the sealing ring 13. Through the limiting cooperation between the conical valve 3 and the sealing ring 13, the weight of the material causes the conical valve 3 to press tightly against the sealing ring 13, completing the sealing of the gap in the pipe 1. Simultaneously, the opening of the groove 14 causes the accumulated material to automatically fall off, achieving the purpose of preventing material blockage and ensuring sealing reliability.

[0026] A flange ring 11 is connected to the top of pipe 1. Multiple discharge pipes 12 are connected between the flange ring 11 and pipe 1, and are arranged around pipe 1 in a gradient distribution. When the cone valve 3 is not raised, the material will fall from the discharge pipe 12 into pipe 1 and press against the cone valve 3. At this time, the cone valve 3 and the sealing ring 13 abut against each other to form a seal. When the cone valve 3 is gradually raised, a gap will be generated between pipe 1 and cone valve 3, and the material will flow out from the gap. As the cone valve 3 continues to rise, the edge of the cone valve 3 will rise to the lowest position of the discharge pipe. The upper part of the material pipe 12 is connected to the pipe 1. While the material is discharged from the gap between the pipe 1 and the cone valve 3, it is also discharged from the pipe connected between the discharge pipe 12 and the pipe 1. By continuing to raise the cone valve 3, the discharge pipe 12 can be opened step by step, thus controlling the speed of material discharge. Through the linkage between the raising and lowering of the cone valve 3 and the gradient discharge pipe 12, the pipes of the discharge pipe 12 and the pipe 1 are connected step by step when the cone valve 3 is raised. This realizes the dual-channel graded discharge of material from the gap and the discharge pipe 12, achieving the purpose of precise control of the discharge flow rate.

[0027] To facilitate the lifting of the cone valve 3, a central sleeve 2 for the lifting arm 21 to rotate is provided inside the pipe 1. The central sleeve 2 extends outward from the pipe 1 and has a rotating shaft 22 on it. The lifting arm 21 rotates around the rotating shaft 22. A handle 24 is connected to the outer end of the lifting arm 21, and the inner end of the lifting arm 21 extends towards the center of the cone valve 3, corresponding to the lifting rod 31 connected to the center of the cone valve 3. A bearing wheel 23 is also connected to the bottom of the lifting rod 31. The lifting arm 21 extends to the bottom of the bearing wheel 23. When the lifting arm 21... When rotating around the pivot 22, the lifting arm 21 and the bearing wheel 23 engage to make the lifting rod 31 rise and fall within the central sleeve 2, that is, the lifting rod 31 rises and falls within the pipe 1, thereby controlling the rise and fall of the cone valve 3 within the pipe 1. Through the lever engagement between the lifting arm 21 and the bearing wheel 23, turning the handle 24 drives the lifting arm 21 to rotate around the pivot 22, causing the end of the lifting arm 21 to push against the bearing wheel 23, driving the lifting rod 31 to rise and fall within the central sleeve 2, thereby completing the smooth lifting / lowering of the cone valve 3 and achieving the purpose of adjusting the valve opening with effort.
