[0027] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0031] See also Figure 1 and Figure 2 The utility model provides a powder transportation device, including a first shell 1, a transportation component 2 and a transmission component 3. A feed port (not shown in the figure) and a discharge port (not shown in the figure) are respectively arranged on both sides of the first shell 1. The transportation component 2 includes a rotating shaft 21, a bearing 22 and a spiral blade 23. The bearing 22 is connected to the rotating shaft 21. A cooling chamber (not shown in the figure) is opened inside the rotating shaft 21. Both ends of the rotating shaft 21 are connected to a conveying pipe (not shown in the figure) for conveying a cooling medium. The conveying pipe is connected to the cooling chamber. The rotating shaft 21 passes through the first shell 1 and is rotatably connected to the first shell 1. The spiral blade 23 is located inside the first shell 1 and is fixedly connected to the rotating shaft 21. The transmission component 3 includes a driving member 31, which is connected to the rotating shaft 21 and is used to drive the rotating shaft 21 to rotate.

[0032] Among them, the position where the feed port is set in the first shell 1 is fixedly connected to the feed pipe 11, and the position where the discharge port is set is fixedly connected to the discharge pipe 12. The first shell 1 is a hollow horizontal tubular structure, and the feed pipe 11 and the discharge pipe 12 are respectively arranged at the top and bottom of the first shell 1, and the feed pipe 11 and the discharge pipe 12 are both vertically arranged; the rotating shaft 21 is made of heat-conducting material, the rotating shaft 21 and the spiral blades 23 are both coaxially arranged with the first shell 1, the spiral blades 23 are welded on the rotating shaft 21, the cooling chamber is coaxial with the rotating shaft 21, and both ends of the cooling chamber are connected to the outside world; two bearings 22 are provided, and the inner walls of the two bearings 22 are respectively fixedly connected to the two ends of the rotating shaft 21.

[0033] In this way, the high-temperature powder is transported to the inside of the first shell 1 through the feed pipe 11, and the driving member 31 drives the rotating shaft 21 to drive the spiral blade 23 to rotate, so that the powder inside the first shell 1 is transported to the discharge pipe 12 by the spiral blade 23, thereby realizing the transportation of the high-temperature powder; the cooling medium is transported to the cooling chamber through the conveying pipe, which can enable the cooling medium with a lower temperature to exchange heat with the rotating shaft 21 with a higher temperature, thereby reducing the temperature of the rotating shaft 21, and further reducing the heat transported from the rotating shaft 21 to the bearing 22, thereby avoiding the bearing 22 being in a high temperature state for a long time and causing the bearing 22 to fail.

[0034] It can be understood that the specific structure and diameter of the feed pipe 11 and the discharge pipe 12 can be adjusted according to actual needs as long as the transportation of high-temperature powder can be achieved. In this embodiment, the feed pipe 11 and the discharge pipe 12 are both flange pipes; the cooling medium can be a fluid with good thermal conductivity such as air and water. In this embodiment, the cooling medium is water; the material of the rotating shaft 21 can be adjusted according to actual needs. In this embodiment, the rotating shaft 21 is made of stainless steel.

[0035] See also Figure 1 In some embodiments, the two ends of the rotating shaft 21 are connected with rotating joints 211, and the rotating joints 211 are connected to the delivery pipeline. The two ends of the rotating shaft 21 extend out of the first shell 1, and the rotating joints 211 are located outside the first shell 1.

[0036] In this way, the conveying pipeline is connected to the rotating shaft 21 through the rotating joint 211, so that the rotating shaft 21 can keep the positions of the rotating joint 211 and the conveying pipeline unchanged during the rotation process, thereby preventing the rotating shaft 21 from driving the conveying pipeline to rotate and affecting the delivery of the cooling medium. During the operation of the rotating shaft 21, the cooling medium can be stably delivered to the cooling chamber, thereby improving the cooling effect of the cooling medium on the rotating shaft 21.

[0037] See also Figure 1 In some embodiments, the bearing 22 is connected to a cooling member 221 for cooling the bearing 22. Two bearings 22 are provided, and one cooling member 221 is connected to each bearing 22.

[0038] In this way, the cooling member 221 can cool the bearing 22 and reduce the temperature of the bearing 22 itself, thereby preventing the powder conveying device from not being able to work normally due to deformation or falling off of the bearing 22 in a high temperature environment.

[0039] See also Figure 1 In some embodiments, the cooling member 221 is a cooling sleeve, which is sleeved on the bearing 22. The hollow cooling sleeve is provided with a liquid inlet and a liquid outlet for allowing the cooling medium to flow in the cooling sleeve. The hollow cooling sleeve is sleeved on the bearing 22 and is fixedly connected to the bearing 22.

[0040] It should be noted that when the cooling medium enters the cooling sleeve through the liquid inlet, the cooling medium with a lower temperature can exchange heat with the bearing 22 with a higher temperature, so that the heat transferred from the rotating shaft 21 to the bearing 22 is transferred to the outside through the cooling medium, thereby reducing the temperature of the bearing 22 itself and making the bearing 22 less likely to deform or fall off due to the high temperature environment.

[0041] It is understandable that the cooling member 221 may also be a structure such as a fan, which can reduce the temperature of the bearing 22 without affecting the normal operation of the bearing 22. The specific structure of the cooling member 221 can be adjusted according to actual needs and will not be listed in detail here.

[0042] See also Figure 1 and Figure 2 In some embodiments, the bearing 22 is connected to a support seat 4 for supporting the bearing 22 and the rotating shaft 21. One bearing 22 is connected to one support seat 4, and the support seat 4 is fixedly arranged below the bearing 22.

[0043] In this way, the support seat 4 can stably support the rotating shaft 21 and the bearing 22 and absorb part of the heat of the bearing 22, so that the bearing 22 can work stably and avoid falling off, shaking, etc.

[0044] See also Figure 1 In some embodiments, the powder transporting equipment further includes a second shell 5, one end of which is connected to the first shell 1, the interior of the first shell 1 and the interior of the second shell 5 are independent of each other, and the second shell 5 is provided with a heat dissipation port 51 for transferring the heat transferred from the first shell 1 to the second shell 5 to the outside.

[0045] Partition plates (not shown) are provided at both ends of the first shell 1 to separate the interior of the first shell 1 from the interior of the second shell 5 , and two bearings 22 are fixedly connected to one end of the two second shells 5 facing away from the first shell 1 .

[0046] In this way, when conveying high-temperature powder, the heat of the first shell 1 is transferred to the second shell 5 through the partition, so that the heat can be transferred to the outside through the heat dissipation port 51, further improving the heat dissipation effect, reducing the heat transferred to the bearing 22, and preventing the bearing 22 from being in a high-temperature environment for a long time.

[0047] See also Figure 1 In some embodiments, the heat dissipation port 51 and the feed port are located on the same side of the first housing 1 . That is, the heat dissipation port 51 is disposed on the top of the second housing 5 .

[0048] In this way, the powder delivered to the first shell 1 through the feed pipe 11 has a higher temperature, and the heat is quickly transferred to the outside through the heat dissipation port 51 , which can improve the heat dissipation and cooling efficiency and reduce the heat transferred to the bearing 22 .

[0049] See also Figure 1 In some embodiments, two second shells 5 are provided, and the two second shells 5 are respectively connected to the two ends of the first shell 1, and the first shell 1 is coaxially arranged with the second shell 5. The two second shells 5 have the same length, and the feed pipe 11 and the discharge pipe 12 are respectively arranged at the two ends of the first shell.

[0050] In this way, two second shells 5 are correspondingly arranged at both ends of the first shell 1, so that the heat inside the first shell 1 can be transferred to the two second shells 5 through the two ends of the first shell 1, and transferred to the outside through the two heat dissipation ports 51, so that the heat dissipation is more uniform, and the temperature of the two bearings 22 is reduced, so that the bearings 22 are not easily malfunctioned, deformed, or fallen off due to being in a high temperature environment.

[0051] See also Figure 1 In some embodiments, the transmission assembly 3 further includes a transmission member 32, and the transmission member 32 is connected to the driving member 31 and the rotating shaft 21. Further, the driving member 31 is a reduction motor, and the transmission member 32 is a chain.

[0052] The reduction motor is arranged on one side of the second housing 5 , and the output shaft and the rotating shaft 21 of the reduction motor are fixedly provided with sprockets (not shown in the figure), and the chain is connected to both sprockets, so that the reduction motor can drive the rotating shaft 21 to rotate.

[0053] It is understandable that the specific structures of the transmission member 32 and the driving member 31 can be adjusted according to actual needs and are not limited to reduction motors and chains. It only needs to be able to drive the rotating shaft 21 to rotate, and no further examples are given here.

[0054] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
