A first feature being "below", "below" and "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.
[0022] During the production of granular silicon, a lot of powder will accumulate in the horizontal pipes and cannot be carried to the downstream equipment with the airflow. Therefore, during each shutdown and maintenance period, the powder accumulated in these horizontal pipes needs to be cleaned; because the horizontal pipes are long and the amount of powder is large, the operator is generally required to wear protective clothing and dust masks for manual cleaning. During the cleaning process, the powder near the deep part of the pipe is more difficult to clean, and some even directly adhere to the inner wall of the pipe, requiring manual cleaning by the staff, which is more laborious.
[0023] See also Figure 1 The present application provides a device for cleaning powder in a pipeline, including a push rod 1, a push plate 2 and a blowing device 3. An air inlet channel is provided inside the push rod 1, the push plate 2 is installed at one end of the push rod 1, and the blowing device 3 is installed on the push plate 2. A plurality of air outlet holes 30 are provided on the blowing device 3, and each air outlet hole 30 is arranged in a divergent shape on the blowing device 3, and the air inlet channel is connected to each air outlet hole 30.
[0024] During use, the staff holds the push rod 1 and extends one end provided with the push plate 2 into the depth of the pipeline, and scrapes out the granular silicon powder in the depth through the push plate 2. During the cleaning process, for the granular silicon powder adhering to the inner wall of the deep pipeline, the air pump can be connected to the push rod 1, and high-pressure air is sent to the blowing device 3 through the air pump. The high-pressure air will be blown out from the various air outlets 30 of the blowing device 3, thereby blowing off the granular silicon adhering to the inner wall of the pipeline. This device can facilitate the staff to clean the powder deep in the pipeline, and can also blow off the powder on the inner wall of the pipeline, so that the cleaning effect is better and labor-saving.
[0025] In order to facilitate carrying and transportation, in some embodiments, the push rod 1 is detachably connected to the push plate 2. When it is needed to be used, the push plate 2 and the push rod 1 are disassembled and reassembled when used.
[0026] Specifically, a blind hole is provided on the push plate 2, an internal thread is provided in the blind hole, an external thread is provided on the pipe wall at one end of the push rod 1, and one end of the push rod 1 is threadedly connected in the blind hole.
[0027] In order to facilitate the adjustment of the length of the push rod 1 so that the extension length of the push plate 2 can be adjusted, in some embodiments, the push rod 1 includes a plurality of segmented tubes 10, and each segmented tube 10 is detachably connected.
[0028] Specifically, an outer wall at one end of the segmented pipe 10 is provided with an outer thread, and an inner wall at the other end of the segmented pipe 10 is provided with an inner thread. The segmented pipes 10 are connected in sequence through threaded connection, and the segmented pipes 10 are connected in sequence to form an air intake channel therein.
[0029] In order to improve the sealing performance between the segmented pipes 10 , in some embodiments, a sealing gasket is provided between two adjacent segmented pipes 10 , so as to effectively prevent the gas in the air intake passage from leaking from the connection gap between the two adjacent segmented pipes 10 .
[0030] In order to facilitate the connection with the air pump, a connecting nozzle is installed at one end of the push rod 1 away from the push plate 2, and the connecting nozzle is used to connect the air pipe on the air pump.
[0031] In some other embodiments, an air intake pipe is provided in the air intake passage, and the air intake pipe is connected to each air outlet hole 30 .
[0032] In this way, the air intake passage only serves as a passage for installing the air intake pipe, and the air intake pipe is directly connected to the air outlet 30 on the blowing device 3 and the air pump, so that the disadvantage of air leakage between the segmented pipes 10 can be completely avoided.
[0033] In some embodiments, the push plate 2 is a fan-shaped structure. The arc edge of the push plate 2 is used to correspond to the inner wall of the pipeline. When the staff pulls the push rod 1, the powder is brought out through the push plate 2.
[0034] In some embodiments, the blowing device 3 is a conical structure, and each air outlet 30 is provided on the conical surface of the blowing device 3. This makes it easier to extend the push plate 2 into the deep part of the pipeline.

A first channel 300 is opened in the middle of the blowing device 3. A plurality of divergent second channels 301 are arranged inside the blowing device 3. The second channels 301 form air outlet holes 30 on the cylindrical conical surface of the blowing device 3.
[0036] In addition, since the push rod 1 is arranged at a position close to the center of the circle on the push plate 2, the first channel 300 of the blowing device 3 and the air intake channel inside the push rod 1 are offset from each other. In some embodiments, the first channel 300 is arranged as a curved structure to connect the air intake channel inside the push rod 1, and a corresponding through hole is provided on the push plate 2, so that the curved first channel 300 is connected to the through hole and the air intake channel.
[0037] Of course, the specific shape of the blowing device 3 is not limited, and it can also be set as a cylindrical structure, and then a circle of air outlet holes 30 are circumferentially arranged on the cylindrical blowing device 3 for air outlet.
