The first connecting flange 61 and the second connecting flange 72 are fixed by bolts.

[0034] The cleaning nozzle includes a first branch pipe 8 and a second branch pipe 9, which are staggered at 90° with each other, and a layer of tower plate is arranged between the first branch pipe 8 and the second branch pipe 9. The first branch pipe 8 is provided with a plurality of first cleaning liquid injection holes toward the upper disk surface of the tower plate 2, and the second branch pipe 9 is provided with a plurality of second cleaning liquid injection holes toward the upper disk surface of the tower plate 2.

[0035] Preferably, in this embodiment, a tray installation position 71 is provided between the first branch pipe 8 and the second branch pipe 9 , and the tray 2 is sleeved on the tray installation position 71 .

[0036] The angle between the water column sprayed from the first cleaning liquid spray hole and the upper plate surface of the tower plate 2 is 60°, and the water column sprayed from the first cleaning liquid spray hole pushes the waste residue to the tower plate slag discharge hole 21.

[0037] The pneumatic slag discharge device includes a pneumatic drive device 10 and a rotating shaft 11. A slag discharge channel 111 is provided on the rotating shaft 11. The pneumatic drive device 10 drives the rotating shaft 11 to rotate. When the rotating shaft 11 rotates 90°, the slag discharge channel 111 is aligned with the tower plate slag discharge through hole 21.

[0038] The rotating shaft 11 is disposed on the lower surface of the adjacent tray 2 , and the rotating shaft 11 is disposed close to the lower end of the slag discharge through hole 21 .

[0039] A positioning sleeve 23 is integrally provided in the middle of the tower plate 2, and the hollow stirring shaft 7 is provided through the positioning sleeve 23; the side of the tower plate 2 is fixed to a local position of the inner wall surface of the cylindrical barrel 1 by bolt connection.

[0040] The outer end of the rotating shaft 11 is connected to the pneumatic drive device 10, and the inner end of the rotating shaft 11 is connected to the positioning sleeve 23 via a pin or bolt. As an example, the pneumatic drive device 10 is arranged outside the cylindrical barrel 1, and the pneumatic drive device 10 includes a pneumatic motor.

[0041] A sewage outlet 12 is provided at the lower end of the cylindrical barrel 1, and an arc-shaped guide plate 13 is provided at the inner port position of the sewage outlet 12 of the cylindrical barrel 1. The edge of the arc-shaped guide plate 13 is fixedly connected to the inner wall surface of the cylindrical barrel 1, and the waste residue slides to the inner port of the sewage outlet 12 through the arc-shaped guide plate 13.

[0042] Preferably, in this embodiment, nine layers of tower plates 2 are sequentially arranged on the hollow stirring shaft 7 from top to bottom.

[0043] In actual application, the cylindrical barrel 1 is made of stainless steel, which has excellent corrosion resistance, temperature resistance and mechanical properties, and provides a contact space for gas-liquid or liquid-liquid.

[0044] There are multiple vertical through holes of different sizes on each tower plate 2. There is a uniform cross-flow on each tower plate. The gas and liquid phases must maintain close and sufficient contact to provide a sufficiently large and constantly updated interphase contact surface for the mass transfer process to reduce the mass transfer resistance; the gas and liquid phases flow in a countercurrent in the cylindrical cylinder to provide a larger mass transfer driving force.

[0045] The installation method for the tray 2 and its mounting hardware must balance structural strength, sealing, maintainability, and thermal expansion requirements. The tray and cylindrical shell are connected via tray mounting hardware. The tray edge rests on the tray mounting hardware on the inner wall of the tower body and is secured with bolts from above. The tray mounting hardware is connected to the tower body with bolts or set screws. Corrosion-resistant gaskets are installed between the tray mounting hardware and the cylindrical shell to minimize edge clearance. This mounting method is removable for easy cleaning or replacement.

[0046] The motor shaft of motor 3 is directly inserted into the hollow shaft of the reducer. The reducer uses helical gears. The core advantage of using helical gears (helical cylindrical gears) is that the tilted design of the gear teeth optimizes transmission performance, especially in terms of load capacity, transmission stability, and applicable scenarios. It is secured by a keyway or expansion sleeve, eliminating intermediate transmission components. It is suitable for small equipment with limited space or compact servo systems.

[0047] Automatic cleaning: The motor 3 provides the power source, and the motor 3 drives the hollow stirring shaft 7 and the hollow transmission shaft 6 to rotate synchronously; the hollow transmission shaft 6 serves as the core transmission component, which transmits power to the rotary cleaning device, causing it to rotate accordingly. The hollow transmission shaft 6 has both transmission and medium conveying functions, and high-pressure cleaning liquid can be passed into its interior. At the same time, the cleaning water is conveyed to the cleaning nozzle through the internal channel of the hollow transmission shaft 6. The cleaning nozzle includes a first branch pipe 8 and a second branch pipe 9. Cleaning nozzles are assembled along the axial direction of the hollow transmission shaft 6 corresponding to the position of each tower plate. The opening directions of the first branch pipe 8 and the second branch pipe 9 are respectively arranged toward the upper and lower disk surfaces of the tower plate, and the adjacent branches are staggered at 90° up and down. During the rotation of the hollow transmission shaft 6, the high-pressure cleaning liquid is directionally sprayed through the cleaning liquid injection holes of the first branch pipe 8 and the second branch pipe 9, forming an all-round flushing of the attachments on the surface of the tower plate. With the help of the rotating action of the rotary cleaning device, dynamic cleaning operation of each tower plate is realized, thereby achieving efficient cleaning.

[0048] Efficient slag discharge: The hollow stirring shaft 7 is set close to the lower end of the tower plate slag discharge hole 21 to prevent the liquid phase from falling from the tower plate slag discharge hole 21 over a large area; when discharging sewage, the pneumatic drive device 10 distributed on the side of the cylindrical barrel 1 drives the rotating shaft 11 to rotate 90° so that the slag discharge channel 111 is aligned with the tower plate slag discharge hole 21, which facilitates the dirt to fall from the upper tower plate to the lower layer. After cleaning each layer, it is discharged from the sewage outlet 11 at the lower end of the cylindrical barrel 1 and is not easy to be blocked.

[0049] The present invention has a reasonable structural design, integrating the synergistic effects of power transmission, medium transportation and mechanical cleaning. Through the "one shaft dual purpose" of the hollow transmission shaft (transmitting torque and transporting cleaning water), the structure is simple, and the cleaning and maintenance of the key components of the flow plate tower are completed efficiently, ensuring the stable operation of the tower equipment, making the cleaning work efficient, easy to maintain and good in stability.

[0050] In addition, since the pneumatic drive device drives the rotating shaft to rotate, it can realize the stirring of residue, opening and closing of slag discharge holes, and pushing of waste liquid, so as to avoid the residue from clogging the tower plates or pipes, ensure the fluid flow and mass transfer efficiency in the tower, and completely solve the problem of blockage of traditional tower plate channels, making the tower less likely to be blocked, easy to discharge slag, and able to operate continuously without stopping for slag cleaning, which is suitable for industrial continuous production; the 9-layer tower plates realize the step-by-step separation and cleaning of waste slag, with good graded treatment effect, high purification efficiency and good practicality.

[0051] The specific description of the present invention in the above embodiments is only used to further illustrate the present invention and cannot be understood as limiting the scope of protection of the present invention. Technical engineers in this field may make some non-essential improvements and adjustments to the present invention based on the contents of the above invention, which fall within the scope of protection of the present invention.
