[0023] The utility model provides a powder conveying and cooling device, comprising a conveying pipe 1 and a heat exchange component 3. A cooling component 2 is fixedly installed on the top of the heat exchange component 3.

[0024] The cooling assembly 2 includes a cooling box 21, the conveying pipe 1 passes through the cooling box 21, and the conveying pipe 1 and the cooling box 21 are fixedly connected. A fixed shell 23 is provided at the bottom of the cooling box 21, and the bottom of the cooling box 21 and the top of the fixed shell 23 are fixedly connected through a first water pump 22. An impeller 25 is installed inside the fixed shell 23, and the conveying pipe 1 is used to convey powder.

[0025] The heat exchange assembly 3 includes a water collecting shell 31 and a guide pipe 34. The top of the water collecting shell 31 is fixedly connected to a heat exchange box 32. A filler 33 is installed inside the heat exchange box 32. An exhaust fan blade 36 is installed on the top of the heat exchange box 32. The filler 33 is made of ceramic material. The filler 33 serves to increase the heat exchange area, increase the heat exchange amount and evenly distribute water.

[0026] Furthermore, the cooling box 21 is fixedly installed on the top of the heat exchange box 32, and the part of the conveying pipe 1 located inside the cooling box 21 has an S-shaped curved structure. The cooling box 21 is loaded with coolant, which can cool and dissipate heat for the powder in the conveying pipe 1. The input end of the first water pump 22 is fixedly connected to the bottom of the cooling box 21, and the output end of the first water pump 22 is fixedly connected to the top of the fixed shell 23. The first water pump 22 can pump the coolant in the cooling box 21 into the fixed shell 23.

[0027] Furthermore, a rotating rod 24 is fixedly connected to the center of the impeller 25, and the rotating rod 24 is rotatably installed inside the fixed shell 23. One end of the rotating rod 24 passes through the inner wall of the fixed shell 23 and extends outward. One end of the rotating rod 24 is fixedly connected to the first bevel gear 241. One end of the guide pipe 34 is fixedly connected to the bottom of the fixed shell 23, and the other end of the guide pipe 34 extends to the top of the inner cavity of the heat exchange box 32. A nozzle 341 is fixedly connected to the bottom of the guide pipe 34. The nozzles 341 are evenly arranged in a group. The nozzles 341 can evenly spray the coolant onto the filler 33. When the coolant enters the fixed shell 23, the impeller 25 can rotate under the impact of the coolant. The impeller 25 rotates and drives the rotating rod 24 to rotate synchronously around its own axis.

[0028] Furthermore, a heat dissipation port is provided on the top of the heat exchange box 32, and a support frame 35 is fixedly connected to the top of the heat dissipation port. A fixed shaft 361 is fixedly connected to the center of the exhaust fan blade 36, and the fixed shaft 361 is rotatably connected to the support frame 35.

Preferably, the power transmission member 372 is a belt transmission structure, and the first bevel gear 241 and the second bevel gear 371 cooperate with each other to convert the rotational force of the rotating rod 24 into the rotational force of the transmission rod 37. The power transmission member 372 can convert the rotational force of the transmission rod 37 into the rotational force of the fixed shaft 361, and the rotational force of the fixed shaft 361 can pull the exhaust fan blade 36 to rotate.

[0029] Furthermore, a second water pump 38 is fixedly installed on the surface of the water collecting shell 31, and a connecting pipe 39 is provided between the second water pump 38 and the cooling box 21.

The second water pump 38 can discharge the coolant in the water collecting shell 31 back to the cooling box 21 along the connecting pipe 39.

[0030] The working principle of the present utility model is as follows: during actual operation, the conveying pipe 1 conveys the powder. When the powder passes through the cooling box 21, the coolant in the cooling box 21 cools the powder in the conveying pipe 1. At the same time, the first water pump 22 draws the coolant in the cooling box 21 into the fixed shell 23. The impeller 25 rotates under the impact of the coolant. The impeller 25 rotates and drives the rotating rod 24 to rotate synchronously around its own axis. The rotating rod 24 rotates and drives the transmission rod 37 to rotate synchronously around its own axis through the first bevel gear 241 and the second bevel gear 371. The transmission rod 37 rotates and drives the fixed shaft 361 to rotate synchronously around its own axis through the power transmission member 372. The fixed shaft 361 rotates and drives the exhaust fan blades 36 to rotate synchronously around the axis of the fixed shaft 361.

[0031] The coolant in the fixed shell 23 then enters the heat exchange box 32 along the guide pipe 34, and then the coolant is evenly sprayed to the filler 33 by the nozzle 341, forming a water film and dissipating heat. The rotation of the exhaust fan blades 36 accelerates the flow of air and discharges the hot air from the top of the heat exchange box 32 to the outside. The coolant on the filler 33 enters the water collecting shell 31 under the action of its own gravity. The second water pump 38 discharges the coolant in the water collecting shell 31 back to the cooling box 21 along the connecting pipe 39. This cycle is repeated to prevent the coolant in the cooling box 21 from accumulating heat.
