Description

Technical Field

[0001] The invention relates to the technical field of drum dryers, in particular to a rotary joint used for a novel drum dryer. Background Art

[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. The main forms of intermittent dryers on the market are: box dryers, rake dryers, double-cone rotary dryers, stirring dryers, spiral cone dryers, 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 external atmosphere; the second is to have an air inlet and outlet isolation function to enable the air inlet and outlet of the drum to be sequentially changed. Currently, there is no rotary joint on the market that can have the above two functions at the same time. Therefore, it is urgent to design a rotary joint for the new drum dryer. Summary of the invention

[0004] The object of the present invention is to provide a rotary joint for a novel drum dryer to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a rotary joint for a new drum dryer, comprising a main body, wherein two main bodies are provided, and the main bodies are connected to each other through springs, a static ring is provided on the side of the main body away from the spring, and a dynamic ring is provided on the side of the static ring away from the spring, the dynamic ring is connected to a main shaft through a bearing, an air guide pipeline is provided on the main shaft, a partition is fixedly installed at the middle position inside the static ring, a permanent magnet core is provided inside the main body, and an oil seal is provided between the main body and the main shaft.

[0006] Preferably, the interior of the static ring is divided into an upper air chamber and a lower air chamber by a partition, and the upper air chamber and the lower air chamber are of the same size.

[0007] Preferably, an air outlet is fixedly installed on the top of the upper air chamber, and an air inlet is fixedly installed on the bottom of the lower air chamber.

[0008] Preferably, a plurality of air guide pipes are provided, and the air guide pipes are fixedly connected to the upper air chamber and the lower air chamber respectively.

[0009] Preferably, two upper air chambers and two lower air chambers are provided respectively, and the air outlet and the air inlet are symmetrically arranged up and down.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] The rotary joint used for the new drum dryer has a moving ring connected to the main shaft and rotates synchronously with the main shaft. The moving ring has holes along the circumference, which are respectively connected to the air guide pipes. The static ring is fixed and a partition is arranged in the diameter direction of the static ring. The static ring is divided into two upper and lower chambers along the axial direction. The two chambers are respectively connected to the dryer air inlet pipe and the exhaust pipe. The air guide pipe is used to introduce dry gas into the dryer drum and discharge wet gas from the dryer drum. As the dryer drum rotates, the air inlet and air outlet of the dryer drum It keeps changing, but the air holes located in the lower semicircle of the drum are always kept in the air intake state, and the air holes located in the upper semicircle of the drum are always kept in the air outlet state, forming an airflow from bottom to top in the drum, making the material present an approximate fluidized state or boiling state, and the moisture containing the solvent (or water) is discharged out of the device through the exhaust holes to achieve material drying. As a whole, it is suitable for processing lightweight materials, materials that are easy to fly, materials that are easy to agglomerate, materials that are easy to hang on the wall, paste-like materials and other difficult-to-handle materials. At the same time, it has high drying efficiency and is easy to use. The special gas distributor is not easy to be blocked, and the gas distributor is evenly distributed without dead angles, which can reduce hanging on the wall and increase flux.
