[0028] The swing assembly 16, the outer wall of the nozzle 13 is fixedly connected with a connecting plate 164, and the connecting plate 164 is fixedly connected to the movable plate 163, the movable plate 163 is movably sleeved on the outer wall of the liquid dispensing tube 11, and the movable plate 163 is movably connected to the annular block 14 through a spring 165, the movable plate 163 is in contact with the fixed plate 161, and the fixed plate 161 is fixedly connected to the inner wall of the washing tower body 1, so as to facilitate the movable liquid discharge of the nozzle 13.

[0029] The driving shaft 6 and the liquid outlet pipe 10 are both rotatably connected to the protection frame 8 through bearings, and the outer wall of the protection frame 8 is fixedly connected with a connecting rod 9, which is fixedly connected to the inner wall of the washing tower body 1 to ensure the normal rotation of the driving shaft 6 and the liquid outlet pipe 10.

[0030] The bevel gear set 7 is composed of two meshing bevel gears, wherein the two meshing bevel gears are respectively fixedly sleeved on the outer wall of the driving shaft 6 and the outer wall of the liquid outlet pipe 10, and the rotation of the driving shaft 6 drives the liquid outlet pipe 10 to rotate.

[0031] The liquid dispensing tube 11 is in a "cross" shape.

[0032] The liquid outlet pipe 12 is a corrugated tube, and every two liquid outlet pipes 12 distributed at a distance form a group and are arranged in the tube body of a section of the liquid distribution pipe 11. The two liquid outlet pipes 12 and the nozzles 13 fixedly connected to the lower ends of the liquid outlet pipes 12 are fixedly connected through a connecting plate 164. In this way, when the movable plate 163 moves to mobilize the nozzles 13 of each group to move, the corrugated tube has toughness and will not affect the water supply of the liquid distribution pipe 11 to the nozzles 13.

[0033] There are two fixed plates 161, and the two fixed plates 161 are symmetrically arranged with reference to the central axis of the washing tower body 1 as the symmetry axis, and inclined surfaces 162 are provided on both sides of the fixed plate 161, and the inclined surfaces 162 are in contact with the movable plate 163, so that the liquid dispensing tube 11 rotates and drives the movable plate 163 to rotate synchronously against the inclined surfaces 162 on both sides of the fixed plate 161, and at this time, the fixed plate 161 pushes the movable plate 163 to move.

[0034] The spring 165 is movably sleeved on the outer ring of the dispensing tube 11, and the two ends of the spring 165 are fixedly connected to the annular block 14 and the movable plate 163 respectively. Under the resetting action of the spring 165, the resetting movement of the movable plate 163 is facilitated, and the nozzle 13 is moved back and forth intermittently by the same logic. The nozzle 13 can move in multiple directions to discharge water, ensuring a higher coverage rate.

[0035] Working principle: When using a chemical washing tower, firstly, the driving shaft 6 connected to the output shaft of the motor 5 is driven to rotate by starting the motor 5, and the two meshing bevel gears in the bevel gear set 7 are driven to rotate the liquid outlet pipe 10 and the liquid distributor 11 fixedly connected to the bottom of the liquid outlet pipe 10 during the driving shaft 6 rotation, so that the spray head 13 can move to discharge water, and at the same time, the end of the liquid distributor 11 is fixedly connected to the annular block 14, and the annular block 14 moves inside the annular groove 15 reserved inside the washing tower body 1, so that the annular movement of the liquid distributor 11 is more stable, and at the same time, the spray liquid sprayed by the movable spray head 13 can well and comprehensively cover the filler and gas contact inside the washing tower body 1, so as to ensure the purification effect;

[0036] During the rotation of the dispensing tube 11, the movable plate 163 movably sleeved on the outer ring of the "cross"-shaped tube body of the dispensing tube 11 is synchronously driven to move in an annular manner, so that the movable plate 163 is fitted with the inclined surfaces 162 on both sides of the fixed plate 161. As the dispensing tube 11 rotates, the movable plate 163 synchronously rotates to press against the inclined surfaces 162 on both sides of the fixed plate 161. At this time, the fixed plate 161 pushes the movable plate 163 to move, and then drives each group of nozzles 13 to move through the connecting plate 164 fixedly connected to the movable plate 163. At the same time, the resetting action of the spring 165 facilitates the resetting movement of the movable plate 163, and then similarly enables the nozzle 13 to move reciprocatingly and intermittently, and the nozzle 13 can move in multiple directions to discharge water, thereby ensuring a higher coverage rate.
