Example 1
The present embodiment provides a furnace tube cleaning nozzle, as shown in fig. 1 and 2, including:
the middle of the pipe body 1 is provided with a hollow channel;
the cover body 3 is covered on the top of the pipe body 1;
the rotating body 2 is limited by the cover body 3 and fixed on the top of the pipe body 1;
the end of the top of the pipe body 1 is provided with a limber hole 11 leading to the side wall, a hollow runner 20 communicated with the limber hole 11 is arranged in the middle of the rotator 2, the top of the rotator 2 is an inclined plane, a top nozzle 21 is arranged on the inclined plane, a side nozzle 22 is arranged on the side surface of the rotator 2, the communication channels of the top nozzle 21 and the side nozzle 22 and the runner 20 are not coplanar with the vertical surface of the central axis of the rotator 2, and cleaning liquid flows through the hollow channel of the pipe body 1, the limber hole 11 and the runner 20 of the rotator 2 and can drive the rotator 2 to rotate when sprayed out from the top nozzle 21 and the side nozzle 22.
Further, the flow passage 20 has a hemispherical shape. The hemispherical flow passage 20 can store a certain amount of cleaning liquid to achieve the effect of increasing the ejection pressure of the top nozzle 21 and the side nozzle 22.
Further, the angle between the top surface of the rotating body 2 and the vertical plane of the central axis of the rotating body 2 is 30-60 °, such as 30 °, 40 °, 50 °, 60 °, etc.
Further, as shown in fig. 3, the rotating body 2 is further provided with a sliding block 23 on the side surface, and a part of the side nozzle 22 can be shielded by adjusting the position of the sliding block 23, so as to adjust the water spraying amount of the side nozzle 22.
Furthermore, the slide block 23 is provided with a boost groove 24, the boost groove 24 is opened on the side surface of the slide block 23, and the position of the slide block 23 is adjusted so that part or all of the liquid in the side nozzle holes 22 can be ejected from the boost groove 24 to adjust the rotation speed of the rotating body 2.
In the furnace tube cleaning nozzle of the present embodiment, the cleaning liquid can rotate the rotating body 2 when the cleaning liquid flows through the hollow passage of the tube body 1, the water passage 11, and the flow passage 20 of the rotating body 2 and is ejected from the top nozzle 21 and the side nozzle 22. The rotation of the rotating body 2 is completed without additional power equipment, and the cleaning liquid sprayed from the top nozzles 21 and the side nozzles 22 improves the spraying range of the cleaning liquid and improves the cleaning effect.
Example 2
The present embodiment provides a furnace tube cleaning apparatus, as shown in fig. 4, including:
a frame 7;
the supporting frame 6 is positioned in the frame 7 and used for supporting the furnace tube 9 so that the furnace tube 9 is vertically and fixedly arranged, and the opening of the furnace tube 9 is positioned at the bottom;
the lifting cleaning assembly 8 is used for extending into the furnace tube 9 to clean the interior of the furnace tube 9;
the lifting cleaning assembly 8 comprises a lifting driving member 81, a U-shaped tube 82, and a furnace tube cleaning nozzle as described in embodiment 1 disposed at the end of the U-shaped tube 82;
the U-shaped pipe 82 can penetrate through the support frame 6 (the support frame 6 is of a hollow structure) and extend into the furnace tube 9 from the opening at the bottom of the furnace tube, and the lifting driving piece 81 drives the U-shaped pipe 82 to drive the furnace tube cleaning nozzle to do lifting motion in the furnace tube 9.
Further, a flexible baffle 83 is further arranged on the U-shaped pipe 82, and when the U-shaped pipe 82 is lifted to the topmost end, the flexible baffle 83 is used for delaying the outflow of the cleaning liquid so that the space from the flexible baffle 83 to the top of the furnace tube 9 can be filled with the cleaning liquid. Because the nozzle can not directly wash the inner wall of the top of the furnace tube, the flexible baffle 83 is arranged to delay the flow of the cleaning solution, so that when the flexible baffle 83 reaches the top of the furnace tube 9, the cleaning solution flexible baffle 83 delaying the flow speed can fill the space at the top of the furnace tube 9 with the cleaning solution (as long as the inflow speed of the cleaning solution is greater than the outflow speed of the cleaning solution from the flexible baffle 83, the cleaning solution can be filled in a certain time), and thus the top of the furnace tube 9 is washed. The flexible baffle 83 can be filled with the cleaning liquid and deform when continuously filling the cleaning liquid to discharge redundant cleaning liquid (equivalent to a one-way valve), and in addition, the existence of the flexible baffle 83 can also enable the cleaning liquid to flow down along the edge of the flexible baffle 83 to wash the inner wall of the furnace tube.
The flexible barrier 83, as shown in fig. 7, includes: a rigid central tray 831, and a flexible rim 832 at the edge of the rigid tray 831. The flexible rim 832 has radially disposed openings 833. If the amount of cleaning fluid is too great, this may deform the flexible edge 832 under pressure to allow cleaning fluid to flow therefrom. The openings 833 can increase the deformability of the flexible edge 832, making the flexible edge 832 more susceptible to deformation.
