Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of grain bins, and more specifically, to a central decompression pipe of a shallow silo with a closure. Background Art
[0002] The central decompression pipe of a shallow silo is a device commonly used in silos and shallow silos. Its main functions are to reduce the breakage rate of grain during storage, reduce the impact of automatic grading, slow down the dynamic load generated by the overall movement of the grain pile during discharge, protect the facilities inside the silo, and extend the service life of the silo and shallow silo. In the existing decompression pipe, the temperature in the central part drops slowly, resulting in an extended ventilation time and increased ventilation energy consumption. The key is that there is an obvious temperature difference between the inside and outside of the grain pile, which easily causes condensation in the grain pile, and then problems such as mildew and insect infestation of the grain occur.
[0003] After retrieval, the Chinese patent with the publication number CN214628250U discloses a ventilation and decompression central pipe for a shallow silo. Through the feeding cone cap and the auxiliary feeding frame at the top of the central pipe body, the grain is evenly fed. The grain falls onto the first anti-breakage cone cap and then slides onto the bottom of the silo through multiple second anti-breakage cone caps, achieving buffer impact, preventing the grain from colliding and breaking, and at the same time preventing the phenomenon of automatic grading of the stored grain in the silo, so that impurities and broken grains are concentrated in the central area, resulting in a small porosity in the central area. At the same time, the central pipe body cooperates with the through holes thereon to assist in air supply to achieve air supply and heat dissipation from the central area of the silo, improving the ventilation effect.
[0004] When the above-mentioned decompression central pipe is in use, the grain falls onto the first anti-breakage cone cap and then slides onto the bottom of the silo through multiple second anti-breakage cone caps. However, the grain directly contacts the first anti-breakage cone cap, which is not convenient for buffering the grain. The pressure of the grain during the falling process is relatively large, which easily causes damage to the cone cap, and the use effect is poor. Content of the Utility Model

[0009] Furthermore, a first connecting plate is fixedly connected to the bottom end of the discharge pipe.
[0010] It can be seen that in the above technical solution, the external pipeline is fixed to the first connecting plate by bolts, which is convenient for transporting grain.

[0013] Furthermore, filters are movably arranged on one side of the plurality of through holes, and the plurality of filters are fixedly embedded and installed on the square pipe.
[0014] It can be seen that in the above technical solution, the plurality of filters block the grain to prevent the grain from entering the connecting pipes.
[0015] Furthermore, air pipes are fixedly communicated with the opposite sides of the two sleeve frames, and second connecting plates are fixedly connected to the opposite ends of the two air pipes.
[0016] It can be seen that in the above technical solution, it is convenient to connect with an external air pipe.

[0030] Furthermore, an air ventilation assembly 7 is arranged outside the square pipe 1. The air ventilation assembly 7 includes two sleeve frames 701 and four connecting pipes 702. The two sleeve frames 701 are respectively fixedly sleeved on the feed pipe 2 and the discharge pipe 5.
