Hierarchical feed tower

Abstract

The invention relates to a hierarchical feed tower. The hierarchical feed tower comprises a barrel body and a hierarchical conical part connected to the lower portion of the barrel body, and the barrel body and the hierarchical conical part are hollow and communicated with each other; an upper feeding hole is formed in the top of the barrel body, and a lower discharging hole is formed in the bottom end of the hierarchical conical part. The hierarchical conical part changes the flow field form of the feed in the feed tower and reduces the friction force and binding force between the powder feed and the inner wall of the tower, and the central flow velocity of the feed in the tower is equal to the peripheral flow velocity during discharging, so that the feed in the tower is in a flowing state. The phenomena of inner wall attachment, caking and the like of the feed in the tower are reduced, the flow field smoothness of discharging is improved, and the feed storage and flowing capabilities of the feed tower are improved.

Description

technical field [0001] The invention belongs to large-scale animal husbandry and breeding equipment, and more specifically relates to a feed tower with a ton-level capacity for storing feed in a feed automatic feeding system. Background technique [0002] The most critical thing in the development of large-scale farms is the feed automatic feeding system, the starting point of the system is as follows figure 1 and figure 2 The feed tower 10 shown is erected on the ground with a vertical support 11, wherein feed is accommodated, and its capacity can reach more than a ton level. [0003] Most feed towers 10 are made of galvanized sheet material or glass fiber reinforced plastics (FRP for short). Its structure comprises a barrel body 12, a conical portion 13 connected under the barrel body 12, an upper material inlet 14 located at the top of the barrel body 11, and a lower discharge opening 15 located at the bottom circle of the conical portion 13. The feed farm uses a feed...

Problems solved by technology

[0004] Due to the materials and manufacturing methods, the inner surface of the feed tower is rough, and the wall thickness is uneven, and there is a large friction and adhesion between the powder (especially dry powder) feed and the inner wall of the barrel. The feed is extremely prone to adhesion to the inner wall and arching in the tower, resulting in problems such as difficulty in discharging, stagnation in discharging, last in first out, mildew of feed, etc.

[0005] In order to solve the above problems, the industry disperses the feed by applying hammering vibration force to the outer wall of the cone of the feed tower, or using airflow to break the condensation of the feed, but the long-term hammering vibration force causes metal fatigue in the feed tower and affects the tank body. The service life may also occur when the condensed and static feed in the tower collapses suddenly, which seriously affects the stability of the discharge.
