Technical elements:

The invention relates to a screw conveyor in the technical field, in particular to a high-temperature water-cooled screw conveyor with simple structure, circulating cooling water circulates in the conveying pipeline conducts heat exchange with high-temperature materials.

In order to achieve the above purpose, the technology adopts the following technical scheme: a high-temperature water-cooled screw conveyor, including the driving device, screw blades, main shaft conveying pipe, the main shaft is set in the main shaft box. The main shaft comprises a plurality of supporting shafts connected in turn. A hanger is arranged on the support shaft, one end of the hanger is connected with the inner wall of the conveying pipe through a bolt, the hanger is sheathed on the support shaft. The bolt blades are arranged on the branch shaft. The end of the main shaft is connected with the shaft through a coupling. Drive connection. A feeding port is arranged above one end of the driving device of the conveying pipe, an outlet is arranged at the other end of the conveying pipe. The conveying pipe is a double-layer structure, the inner part of the conveying pipe is formed between the cooling cavities, the end of the inner cooling cavity near the driving device is provided with a water pump, the cooling box is located near the driving cavity. At the other end of the internal cooling chamber, the cooling tank is connected to the water pump.

When the required spindle length is long, multiple sub axes can be connected in turn to form a longer spindle. At the same time, due to the length of the auxiliary shaft combination, a hanger is used to support each auxiliary shaft, so as to prevent the connection jumping greatly due to the effect of gravity, which will cause serious damage to the machine during operation. The inner cooling cavity is formed in the conveying pipe, the water pump the cooling bin are connected to make the coolant circulate in the conveying pipe, the heat conduction effect of the conveying pipe is good.

A keyway is arranged at one end of the dividing shaft, a hub is arranged at the other end of the dividing shaft, each dividing shaft is connected by a key. The key connection can be easily disassembled between the split shafts, due to the protection of the hanger, there will be too much vibration between the split shafts.

The lower part of the conveying pipe is also provided with a U-shaped frame for placing the conveying pipe.

A plurality of external connecting rings are arranged above the conveying pipe. It can ensure that the screw conveyor can adapt to different working environment.

Technical features:

1. A high-temperature water-cooled screw conveyor, which is characterized in that it includes a driving device, a spiral blade, a main shaft a conveying pipe, the main shaft is arranged in the conveying pipe, the main shaft includes a plurality of branch shafts, which are connected in sequence; a hanger is arranged on the supporting shaft, one end of the hanger is connected with the inner wall of the conveying pipe through a bolt, the hanger is sheathed on the connecting part of each supporting shaft.

Technical summary

The technology discloses a high-temperature water-cooled screw conveyor, which comprises a driving device, a spiral blade, a main shaft a conveying pipeline. The main shaft is arranged in the conveying pipeline. The main shaft comprises a plurality of branch shafts connected in turn. One end of the hanger is connected to the inner wall of the conveying pipe by bolts, the hanger is sheathed on the open shaft. The bolt blade is installed on the open shaft; one end of the main shaft is connected with the driving device through a coupling. A feeding port is arranged above the outlet, a discharging port is arranged at the other end of the conveying pipe. The conveying pipe is a double-layer structure, an internal cooling cavity is formed between the double-layer structures of the conveying pipe, the internal cooling cavity is close to one end of the driver. The cooling box is provided with "water" at the other end of the internal cooling cavity, the cooling box is connected with the water pump. The invention has the advantages that: (1) the structure is simple can be assembled disassembled according to the length requirements;

(2) The circulating water passes through the conveying pipe, the heat exchange is fast.
