The mixing tank is composed of a tank (lid) body, upper and lower heads, agitators, supports, transmission devices, shaft sealing devices, etc. It can also be equipped with heating (cooling) devices or metering devices according to process requirements. Among them, the head is an important part of the stainless steel mixing tank, which plays a role of sealing. Today, i will explain how to choose the head in the design of the lower mixing tank.

The head is a part of the mixing tank. According to the different geometric shapes, the head of the mixing tank can be divided into spherical, elliptical, dish, spherical crown, cone shell and flat cover. Among them, spherical, elliptical, Dish-shaped and spherical crown-shaped heads are also collectively referred to as convex heads. In welding, it is divided into butt welding heads and socket welding heads, which are used in various container equipment, such as storage tanks, heat exchangers, reactors, boilers and separation equipment; elliptical heads: concentration ratio hemispherical seals The head is much smaller and easy to be stamped and formed. It is currently one of the most widely used heads in medium and low pressure vessels. Hemispherical head: It is an ideal structure. But the disadvantage is that the depth is large, the punching is more difficult, and the spherical head uses the least materials. Flat head: Due to the large diameter and thickness, there are many difficulties in processing and welding. The flat head uses the most materials. Therefore, considering the strength, structure, and design and manufacture of the mixing tank, it is more reasonable to adopt an elliptical head.

The head is an indispensable and important part of pressure vessel equipment in the food, pharmaceutical, dairy, petrochemical and other industries. When customizing the mixing tank, the choice of the head can be based on the actual production situation to choose the oval, spherical or flat-bottomed head.
