Embodiment 1

[0021] Embodiment 1 is basically as attached figure 1 Shown: a dust-free and environmentally friendly powder screw conveying device, including a dust suppression mechanism, a conveying cylinder 1 and a screw shaft. One end of the conveying cylinder 1 is provided with a material inlet, and the other end is provided with a discharge port 2. The screw shaft includes a rotating shaft 14 and the helical blade 13 wound around the outer wall of the rotating shaft 14, the two ends of the rotating shaft 14 run through the two ends of the delivery cylinder 1 and are respectively connected with a motor 15 and a rotary joint 3, and the rotating shaft 14 is rotationally connected with the delivery cylinder 1 through the rotary joint 3.

[0022] The dust suppression mechanism includes a water pipe 6 and a plurality of spray pipes 7 connected to the water pipe 6. The distance between the spray pipes 7 is 2-2.5m. The number of the spray pipes 7 depends on the length of the water pipe 6 inside ...

Embodiment 2

[0025] Embodiment 2, the difference with embodiment 1 is: as Figure 4 As shown, a plurality of fan heads 20 are connected to the inside of the top of the delivery tube 1, and the fan heads 20 are connected with fan blades 19. Cables connected to the fan heads 20 are buried inside the wall of the delivery tube 1, and the free ends of the cables extend to the conveyor. The outside of the tube 1 is connected to the power supply, and the fan heads 20 and the spray pipes 7 are arranged alternately.

Embodiment 3

[0026] The difference between embodiment 3 and embodiment 2 is that the spray pipe 7 is a four-way pipe.

[0027] Taking Embodiment 2 as an example, the specific implementation process is as follows: after the water pipe 6 is connected to the water source, the water flows to the spray pipe 7, and under the action of water pressure, the high-pressure atomizing nozzle atomizes the water and sprays it out. The special feature of this solution is that the spray pipe 7 is located on the upper surface of the water pipe 6, and the water outlet 701 of the spray pipe 7 faces upwards. This design makes the sprayed water mist in the spray pipe 7 face upwards first and then under the force of gravity. Under the action, it flows downward again, so that the sprayed water mist flows out in a parabolic shape. This kind of water mist is relatively dispersed, can spray to a larger area, touch more dust, and achieve a good dust reduction effect. Simultaneously, after the fan head 20 is powered ...

Abstract

The invention discloses a dust-free environment-friendly powder spiral conveying device in the field of powder conveying equipment. The dust-free environment-friendly powder spiral conveying device comprises a conveying cylinder and a spiral shaft located in the conveying cylinder, a feeding port is formed in one end of the conveying cylinder, and a discharging port is formed in the other end of the conveying cylinder. The device further comprises a dust falling mechanism, the dust falling mechanism comprises a water pipe and a plurality of spraying pipes communicated with the water pipe, the spraying pipes are distributed on the upper surface of the water pipe at intervals, water outlets of the spraying pipes face upwards, and high-pressure atomizing nozzles are arranged in the spraying pipes. The water pipe is located above the spiral shaft, one end of the water pipe penetrates out of the conveying cylinder and communicates with a water source, and the other end of the water pipe is a blind end. According to the scheme, the spraying pipes are located on the upper surface of the water pipe, and the water outlets of the spraying pipes face upwards, so that water mist sprayed out of the spraying pipes firstly faces upwards and then flows downwards under the action of gravity, and the sprayed water mist flows out in a parabola shape. Therefore, the water mist is relatively dispersed and can be sprayed to a relatively large range to be in contact with more dust, so that a quite good dust falling effect is achieved.

Description

technical field [0001] The invention belongs to the field of powder material conveying equipment, in particular to a dust-free and environment-friendly powder material screw conveying device. Background technique [0002] The screw conveyor is a kind of machine that uses the motor to drive the screw to rotate and push the material to achieve the purpose of conveying. It can be transported horizontally, inclined or vertically, and has the advantages of simple structure, small cross-sectional area, good sealing, convenient operation, easy maintenance, and convenient closed transportation. A conventional screw conveyor includes an outer cylinder, and a screw conveying shaft is arranged inside the outer cylinder. Both ends of the screw conveying shaft run through the two ends of the outer cylinder and are respectively connected with a driving motor and a rotating wheel, and the driving motor drives the screw conveying shaft to rotate; The two ends of the outer cylinder are resp...
