Rotary joint for novel roller dryer

Abstract

The invention discloses a rotary joint for a novel roller dryer. The rotary joint for the novel roller dryer comprises two main bodies, wherein the two main bodies are connected with each other through a spring; a static ring is arranged on the side, away from the spring, of each main body; a movable ring is arranged on the side, away from the spring, of each static ring; and the movable rings areconnected with a main shaft through bearings. According to the rotary joint for the novel roller dryer, movable rings are connected with the main shaft and rotate synchronously with the main shaft, and holes are formed in the movable rings along the circumference and communicate with air guide pipelines respectively; and the static rings are fixed, a partition plate is arranged in the diameter direction of each static ring and axially divides into an upper cavity and a lower cavity, the two cavities are connected with an air inlet pipe and an exhaust pipe of the dryer respectively, and the air guide pipelines are used for guiding dry air into a dryer roller and exhausting wet air out of the dryer roller to achieve the drying of materials, so that the whole device is suitable for treatinglight materials which are easy to fly, easy to cake, easy to hang on the wall, pasty and difficult to treat, and is high in drying efficiency and convenient to use at the same time.

Description

technical field [0001] The invention relates to the technical field of drum dryers, in particular to a rotary joint for a new drum dryer. Background technique [0002] Drying is an important unit operation in industrial production. It is widely used in chemical industry, medicine, light industry, biology, traditional Chinese medicine, food, agricultural product processing and other fields. At present, the main forms of intermittently operated dryers on the market are: box drying Dryer, rake dryer, double cone rotary dryer, stirring dryer, spiral cone dryer, etc. [0003] The new drum dryer requires that the rotary joint must have the following two functions at the same time: one is to have a radial sealing function to isolate the gas inside the dryer from the outside atmosphere; The air port and the air outlet are changed in sequence. At present, there is no rotary joint that can have the above two functions at the same time on the market. Therefore, it is urgent to design ...

Problems solved by technology

[0003] The new drum dryer requires that the rotary joint must have the following two functions at the same time: one is to have a radial sealing function to isolate the gas inside the dryer from the outside atmosphere; The air port and the air outlet are changed sequentially. At present, there is no rotary joint that can have the above two functions at the same time on the market. Therefore, it is urgent to design a rotary joint for a new type of drum dryer.
