[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A sticky dust conveying device with switchable channels comprises a conveying pipe, a connecting shaft, a first conveying channel, a second conveying channel and a feeding pipe, the tops of the first conveying channel and the second conveying channel are fixedly connected with a docking pipe, the conveying pipe and the connecting shaft are integrally formed, a mounting plate is fixedly connected between the two docking pipes, a sealing ring is embedded at one end of the conveying pipe and the connecting shaft, a central shaft is fixedly connected to the bottom of the connection between the conveying pipe and the connecting shaft, and the central shaft passes through the mounting plate, a threaded groove is opened on the outer wall of the central shaft, and a tightening knob is threadedly connected to the outer surface of the threaded groove.

[0007] Furthermore, the top of the material delivery pipe is rotatably connected to a rotating disk, and the feed pipe is connected to the material delivery pipe through the rotating disk.

[0008] Furthermore, a control valve is provided on one side of the feed pipe.

[0009] Furthermore, the butt-jointed tube has an annular slide groove at the top, and a limit baffle is slidably connected in the annular slide groove.

[0010] Furthermore, the limit baffle is an arc-shaped structure.

[0011] Furthermore, the bottoms of the first conveying channel and the second conveying channel are both fixedly connected to two supporting seats.

[0012] Furthermore, one end of each of the first conveying channel and the second conveying channel is provided with a discharge pipe.

[0013] The beneficial effects of the utility model are:

[0014] 1. Through the setting of the conveying pipe and the connecting shaft, the conveying channel can be quickly switched in coordination with the tightening knob and the center shaft, so that the blocked conveying channel can be repaired without stopping the machine, which can ensure the continuous conveying work without causing production interruption.

[0015] 2. Through the coordinated use of the annular slide and the limit baffle, the rotating switching conveying pipe and the connecting shaft can be limited, so that the conveying pipe and the connecting shaft can be aligned with the center of the butt pipe to avoid skewing and gaps, thereby causing leakage and affecting the dust conveying effect.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-Figure 4A viscous dust conveying device with switchable channels comprises a conveying pipe 1, a connecting shaft 2, a first conveying channel 3, a second conveying channel 4 and a feeding pipe 13. The tops of the first conveying channel 3 and the second conveying channel 4 are both connected with a butt pipe 5 through a flange. The conveying pipe 1 and the connecting shaft 2 are integrally formed. A mounting plate 6 is welded between the two butt pipes 5. A sealing ring 7 is embedded at one end of the conveying pipe 1 and the connecting shaft 2. A central shaft 8 is welded at the bottom of the connection between the conveying pipe 1 and the connecting shaft 2, and the central shaft 8 passes through the mounting plate 6. A threaded groove 9 is provided on the outer wall of the central shaft 8, and a tightening knob 10 is threadedly connected to the outer surface of the threaded groove 9. The conveying pipe 1 and the connecting shaft 2 can be used in conjunction with the tightening knob 10 and the central shaft 8 to quickly switch the conveying channel, so that the blocked conveying channel can be repaired without stopping the machine, which can ensure the continuous progress of the conveying work without causing production interruption.

[0023] In the utility model, the top of the conveying pipe 1 is rotatably connected to the rotating disk 14, and the feeding pipe 13 is connected to the conveying pipe 1 through the rotating disk 14. A control valve 15 is provided on one side of the feeding pipe 13, and an annular slide groove 11 is provided on the top of the butt-jointed pipe 5, and a limit baffle 12 is slidably connected in the annular slide groove 11, so that the conveying pipe 1 and the connecting shaft 2 can be aligned with the center of the butt-jointed pipe 5 to avoid skewing and generating gaps, thereby causing leakage. The limit baffle 12 is an arc structure, and two support seats 16 with mounting holes are welded to the bottom of the first conveying channel 3 and the second conveying channel 4, and a discharge pipe 17 is provided at one end of the first conveying channel 3 and the second conveying channel 4.

[0024] The working principle of this embodiment is as follows: during use, when the first conveying channel 3 or the second conveying channel 4 is blocked, the control valve 15 is first closed, and then the tightening knob 10 is turned to loosen it, thereby causing the conveying pipe 1 and one end of the connecting shaft 2 to be separated from the docking pipe 5, and then the conveying pipe 1 and the connecting shaft 2 are rotated so that one end of the conveying pipe 1 is aligned with the top of the unblocked conveying channel, and conversely, one end of the connecting shaft 2 is aligned with the top of the blocked conveying channel, and the limit baffle 12 can slide along the annular slide groove 11, thereby blocking and limiting one end of the conveying pipe 1 and the connecting shaft 2, and finally the tightening knob 10 is turned, and under the action of the threaded groove 9, the central shaft 8 is driven to move downward, so that one end of the conveying pipe 1 and the connecting shaft 2 can be pressed and docked with one end of the docking pipe 5, and then the control valve 15 is opened to ensure the normal transportation of sticky dust, and the blocked conveying channel can be repaired and replaced.

[0025] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
