[0027] Reference below Figures 1 to 4 To describe the pipeline clearing device according to an embodiment of the utility model.

[0028] According to the pipeline unclogging device of the embodiment of the utility model, it includes a drill bit 100, a stirring mechanism 300, a connecting pipe 400 and a blowing assembly 500. The drill bit 100 is connected to a driving motor, and the driving motor drives the drill bit 100 to rotate; the stirring mechanism 300 is arranged behind the drill bit 100 along the forward direction of the drill bit 100, and the stirring mechanism 300 rotates to crush the blockage drilled by the drill bit 100; the connecting pipe 400 is connected to the stirring mechanism 300, and the drill bit 100 and the stirring mechanism 300 penetrate into the pipeline through the connecting pipe 400 for unclogging, and the blowing assembly 500 is arranged behind the drill bit 100 along the forward direction of the drill bit 100, and a plurality of air outlet holes 510 are arranged on the blowing assembly 500.

[0029] For example Figure 1 As shown, the drill bit 100 is arranged at the front, followed by the blowing assembly 500, the stirring mechanism 300 and the connecting pipe 400. The blowing assembly 500 and the stirring mechanism 300 can be arranged in such a way that the blowing assembly 500 is in front and the stirring mechanism 300 is in the back, or the stirring mechanism 300 is in front and the blowing assembly 500 is in the back.

[0030] During operation, the drill bit 100, the stirring mechanism 300 and the blowing assembly 500 enter the powder pipe from the far end of the furnace through the connecting pipe 400, and the drill bit 100 rotates to crush the blockage, so that the entire pipeline dredging device can move forward in the powder pipe, and then the stirring mechanism 300 stirs the crushed coal blocks into small particles of coal powder. After the drill bit 100 reaches the near end of the furnace, the drill bit 100 and the stirring mechanism 300 stop working, and the blowing assembly 500 starts at this time to blow the small particles of coal powder out of the near end of the furnace, and the entire pipeline dredging device turns to the blowing side and moves backward until it finally exits from the powder pipe at the far end of the furnace, thereby clearing the entire powder pipe.

[0031] By adopting the method of blowing and moving backward at the same time, the coal powder near the furnace can be blown out first, thus not hindering the blowing out of the coal powder at the rear.

[0032] Furthermore, the connecting pipe 400 is a stainless steel hose, which makes it easier for the drill bit 100, the stirring mechanism 300 and the blowing assembly 500 to enter the powder hose, and the connection is more stable.

[0033] According to the pipeline clearing device of the embodiment of the utility model, by being configured in this way, at least the following beneficial effects can be achieved: gas is blown out from the blowing assembly 500, forming air pressure in the powder pipe, and the air pressure gradually clears the blockage in the powder pipe, without the need to open a plurality of holes on the powder pipe, thereby avoiding the occurrence of coal powder spraying outward along the openings to pollute the environment, and at the same time achieving the purpose of rapid clearing, reducing labor costs, and avoiding the occurrence of powder pipe damage and coal powder explosion.

[0034] In some specific embodiments of the present invention, the stirring mechanism 300 includes a rotating tube 310 and crushing blades 320 , and a plurality of crushing blades 320 are arranged around the circumference of the rotating tube 310 .

[0035] For example Figure 1 and Figure 2 As shown, the stirring mechanism 300 includes a rotating tube 310 and a crushing blade 320, and a plurality of crushing blades 320 are arranged around the circumference of the rotating tube 310. The stirring mechanism 300 rotates through the rotating tube 310, driving the crushing blades 320 to rotate, so that the crushing blades 320 can break the large-particle coal blocks drilled by the drill bit 100 into fine small-particle coal powder, which is not only convenient for the blowing component 500 to blow the small-particle coal powder into the furnace, but also the coal powder is easier to burn fully after being blown into the furnace, which is convenient for energy utilization.

[0036] Furthermore, the rotating tube 310 is also rotated by a driving motor, and it can share a driving motor with the drill bit 100, or a driving motor can be independently provided for the rotating tube 310.

[0037] Furthermore, the size of the stirring mechanism 300 can be adjusted according to the diameter of the powder hose to ensure that the stirring mechanism 300 can fully clear the powder hose.

[0038] The stirring mechanism 300 adopts the design of the rotating tube 310 and the crushing blade 320, so that the pipeline clearing device can clear the pipeline more fully and facilitate subsequent operations.

[0039] In some specific embodiments of the present invention, the crushing blade 320 is arranged in an arc shape, both ends of the crushing blade 320 are connected to the rotating tube 310, and the middle part is arranged to protrude outward in an arc shape.

[0040] For example Figure 1 and Figure 2 As shown, the crushing blade 320 is arranged in an arc shape, like an arch bridge, with the middle part protruding outward in an arc shape, and both ends are fixedly connected to the rotating tube 310. When the rotating tube 310 rotates, the middle arc part of the crushing blade 320 crushes the blockage into small particles of coal powder.

[0041] By disposing the arc-shaped crushing blade 320, the stirring mechanism 300 can stir in a powder tube with a relatively large diameter with less material, which is convenient for practical use.

[0042] In some specific embodiments of the present invention, the crushing blade 320 is made of elastic material.

[0043] The crushing blade 320 is made of an elastic material. When there are hard objects such as stones in the powder tube, the crushing blade 320 can reduce the collision with these hard objects, thereby avoiding damage to the crushing blade 320.

[0044] In some specific embodiments of the present invention, the blowing assembly 500 is a ring-shaped structure, the inlet of the air outlet 510 is arranged on the inner wall of the blowing assembly 500 and connected to the connecting pipe 400, and the outlet of the air outlet 510 is arranged on the side end surface of the blowing assembly 500.

[0045] For example Figure 1 and Figure 4 As shown, the air blowing assembly 500 is arranged in an annular shape, the inlet of the air outlet hole 510 is arranged on the inner wall of the air blowing assembly 500, and is connected to the connecting pipe 400, and the outlet of the air outlet hole 510 is arranged on the side end surface of the air blowing assembly 500. When the drill bit 100 stops working and the air blowing assembly 500 starts working, air is pumped into the connecting pipe 400 through the air pump, and the air outlet hole 510 is connected to the connecting pipe 400, so that the gas pumped from the air pump can be blown out from the outlet of the air outlet hole 510, so that the coal powder can be blown into the furnace.

[0046] In some specific embodiments of the present invention, the outlet direction of the air outlet hole 510 is arranged toward the drill bit 100 .

[0047] The outlet direction of the gas outlet hole 510 is arranged toward the drill bit 100 , so that after the gas is blown out from the gas outlet hole 510 , the coal powder can be directly blown into the furnace.

[0048] In some specific embodiments of the utility model, an air outlet pipe 600 is also included. The air outlet pipe 600 is connected and communicated with the connecting pipe 400. A small hole 610 is opened on the side wall of the air outlet pipe 600. The blowing component 500 is sleeved on the air outlet pipe 600 and the small hole 610 is communicated with the air outlet hole 510.

[0049] For example Figure 3 As shown, the air outlet pipe 600 is connected and communicated with the connecting pipe 400, a plurality of small holes 610 are provided on the side wall of the air outlet pipe 600, and the air blowing assembly 500 is sleeved on the air outlet pipe 600 so that the small holes 610 and the air outlet holes 510 can be communicated. When the air blowing assembly 500 is working, the gas reaches the connecting pipe 400 from the air pump, reaches the air outlet pipe 600 from the connecting pipe 400, and reaches the air outlet hole 510 from the small holes 610 of the air outlet pipe 600, so that the gas can be blown out in the powder hose.

[0050] In some specific embodiments of the present invention, a plurality of small holes 610 are arranged around the circumference of the air outlet pipe 600 .

[0051] For example Figure 2 and Figure 3As shown, a plurality of small holes 610 are arranged around the circumference of the air outlet pipe 600 , so that the small holes 610 can be more stably connected with the air outlet hole 510 , which facilitates the gas to enter the air outlet hole 510 from the small holes 610 .

[0052] In some specific embodiments of the present invention, the stirring mechanism 300 includes a rotating tube 310, and the air outlet pipe 600, the rotating tube 310 and the connecting tube 400 are connected and communicated in sequence, and one end of the rotating tube 310 is rotatably connected to the air outlet pipe 600, and the other end is rotatably connected to the connecting tube 400.

[0053] For example Figure 1 As shown, the stirring mechanism 300 includes a rotating tube 310, an air outlet pipe 600, the rotating tube 310 and the connecting pipe 400 are sequentially connected and communicated, one end of the rotating tube 310 is rotatably connected to the air outlet pipe 600, and the other end is rotatably connected to the connecting pipe 400, so that it can rotate in the air outlet pipe 600 and the connecting pipe 400, driving the crushing blade 320 to perform stirring. The blowing assembly 500 is sleeved on the air outlet pipe 600, so that the blowing assembly 500 can be located in front of the stirring mechanism 300, so that the stirring mechanism 300 will not affect the blowing of the blowing assembly 500.

[0054] In some specific embodiments of the present invention, a mounting shell 200 is further included. The driving motor is disposed in the mounting shell 200 . The mounting shell 200 is sleeved on the air outlet pipe 600 and is disposed behind the blowing assembly 500 along the forward direction of the drill bit 100 .

[0055] For example Figure 1 The drive motor is placed in the mounting shell 200, which is sleeved on the air outlet pipe 600 and located behind the air blowing assembly 500 to prevent the drive motor from affecting the air blowing assembly 500 to blow out the coal powder. The mounting shell 200 is sleeved on the air outlet pipe 600, which can make the drive motor more stable. The drive motor can drive the drill bit 100 and the stirring mechanism 300 to rotate at the same time.
