[0002] Vertical planetary mixer is a kind of engineering machinery, which is mainly used for mixing concrete, dry mortar, refractory materials and chemical raw materials.

[0003] At present, there are two main types of water inlet pipes for traditional vertical shaft planetary mixers on the market. One is to weld a circle of channel steel around the outer circle of the top of the cylinder as a water channel, but the top surface of the channel steel needs to be drilled to connect to the cylinder cover, which will cause water leakage at the connection hole and drilling debris or sealing material debris will easily clog the nozzle. In addition, this structure has problems such as water cannot be drained cleanly in the water channel and cannot be disassembled and replaced after rusting. The other is to set an external annular water pipe on the top of the cylinder cover. This structure will occupy the layout space of feeding metering, is difficult to arrange, and the external pipeline is complicated and unsightly, and inconvenient for the main machine to repair.

[0022] An annular water spray unit is installed inside the cylinder 1, and a number of nozzles 6 are evenly distributed on the annular water spray unit. Each nozzle 6 forms an angle with the horizontal direction, which can transform the horizontal water flow into an annular spray effect, and can spray a uniform water flow, achieving a good mixed infiltration effect.

[0023] The interface pipe 3 is arranged in a horizontal manner, so that the annular water spray unit can be built inside the cylinder 1. This built-in design solution makes the device occupy a relatively small space and is simple and convenient to operate.

[0033] When working, water flows from the interface pipe to the first arc pipe and the second arc pipe in turn, and sprays fine water droplets through the nozzle to form a mixed water flow. The annular tube body formed by the first arc pipe and the second arc pipe realizes the closed circulation of water flow. The setting of the fixed plate can ensure the stability of the spraying effect and is not affected by the vibration of the machine. The spraying is uniform and stable; it avoids the problem of failure of the reducer seal caused by the traditional water nozzle spraying water at the planetary shaft head seal and the reducer slewing bearing seal.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
