Vertical rotary valve and continuous cooking equipment

Abstract

The invention provides a vertical rotary valve. The vertical rotary valve can ensure the air tightness of a rotor by arranging sealing pieces at fewer or even the same radial position. The vertical rotary valve includes the rotor and a hollow shaft. The rotor includes an outer peripheral portion, an inner peripheral portion, and a plurality of partition plates, the two ends of each partition plate are connected to the outer peripheral portion or the inner peripheral portion, the rotor is divided into a plurality of bins by the outer peripheral portion, the inner peripheral portion, and the plurality of partition plates; and at least one part of the hollow shaft and the rotor coaxially penetrate through the center of the end of the rotor, the hollow shaft is rotationally connected with the rotor, an opening is formed at the part, located in the rotor, of the hollow shaft, and one or more bins in the multiple bins communicate with the hollow part of the hollow shaft through the opening.

Description

technical field [0001] The present invention relates to a vertical rotary valve, and more specifically, the present invention relates to a vertical rotary valve used in a continuous cooking device. Background technique [0002] In the continuous cooking equipment, the raw materials need to be pressure cooked in the water vapor atmosphere in the pressure cooking tank. In order to supply or discharge the raw materials while maintaining the pressure in the pressure cooking tank, the position where the pressure cooking tank is connected to the upstream and downstream equipment is usually equipped with a rotary valve. The rotary valve can be a vertical rotary valve or a horizontal rotary valve. , In the case of a vertical rotary valve, the raw material enters the pressure cooking tank through the vertical rotary valve for input, and leaves the pressure cooking tank through the vertical rotary valve for discharge. [0003] Existing vertical rotary valves for continuous cooking pl...

Problems solved by technology

However, during the preheating process, because the side close to the rotor has a high temperature and a large amount of thermal expansion, while the side close to the external environment has a low temperature and a small amount of thermal expansion, so the upper and lower covers will have a center close to the rotor and an outer edge away from the rotor. The deformation of the first seal ring in the center is easy to wear, and the sealing effect of the second seal ring at the outer edge is poor
