Description

Technical Field

[0001] This utility model relates to the field of cross-flow plate tower technology, and specifically to an automatic cleaning device for cross-flow plate towers. Background Technology

[0002] A cross-flow plate tower is a staged contact mass transfer device used in gas-liquid or liquid-liquid systems. It consists of a cylindrical tower body and several horizontally arranged trays at certain intervals inside the tower.

[0003] Existing cross-flow plate towers, such as sieve plate towers and cross-flow grid plate towers, are prone to efficiency reduction due to solid deposition or scaling during gas-liquid mass transfer, requiring frequent shutdowns for cleaning, resulting in low cleaning efficiency. In addition, the stirring shaft and spray pipes in existing cross-flow plate towers are two independent structures, which are complex, costly to manufacture, troublesome to maintain, have poor stability during operation, and are not very practical. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an automatic cleaning device for cross-flow plate towers that has a reasonable structural design, simple structure, high cleaning efficiency, convenient maintenance, good stability and practicality.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic cleaning device for a cross-flow plate tower, comprising a cylindrical body, a hollow drive shaft vertically arranged inside the cylindrical body, a drive device arranged at the upper end of the hollow drive shaft, and a hollow stirring shaft detachably arranged at the lower end of the hollow drive shaft. The hollow stirring shaft is provided with a plurality of rotating cleaning mechanisms arranged sequentially from top to bottom. Each rotating cleaning mechanism includes a plurality of cleaning nozzles, each cleaning nozzle including a first branch pipe and a second branch pipe, the first branch pipe and the second branch pipe being alternately arranged. The first branch pipe is provided with a plurality of first cleaning liquid injection through holes, and the second branch pipe is provided with a plurality of second cleaning liquid injection through holes.

[0006] The driving device drives the hollow transmission shaft to rotate. The hollow stirring shaft is linked with the hollow transmission shaft. The hollow stirring shaft is provided with multiple connection ports. One end of the first branch pipe and the second branch pipe are respectively fixed to the aligned connection ports by thread or by welding. The hollow stirring shaft simultaneously drives the first branch pipe and the second branch pipe to rotate.

[0007] The present invention is further configured such that: the first branch pipe and the second branch pipe are staggered at 90°; the first cleaning fluid injection through-hole on the first branch pipe is inclined downward at 45-75°; and the second cleaning fluid injection through-hole on the second branch pipe is inclined upward at 45-75°.

[0008] The present invention is further configured such that a tray mounting position is provided between the first branch pipe and the second branch pipe.

[0009] The present invention is further configured such that: a first connecting flange is integrally provided at the lower end of the hollow drive shaft, and a second connecting flange is integrally provided at the upper end of the hollow stirring shaft, and the first connecting flange and the second connecting flange are fixedly connected by bolts.

[0010] The present invention is further configured such that: the driving device includes a motor, a reduction gear and a positioning seat; the positioning seat is fixed to the top of the cylindrical body by bolts or by welding; the upper end of the positioning seat is fixed to the reduction gear by bolts; the motor is fixed to the reduction gear by bolts; the motor shaft is fixed to the reduction gear by a key or a shrink sleeve; the reduction gear includes a helical gear assembly; and the upper end of the hollow transmission shaft is fixed to the helical gear assembly by a key.

[0011] The present invention is further configured such that: the hollow stirring shaft is provided with 9 rotating cleaning mechanisms from top to bottom, each rotating cleaning mechanism including 2 first branch pipes and 2 second branch pipes, wherein the 2 first branch pipes are symmetrically arranged and the 2 second branch pipes are symmetrically arranged.

[0012] The beneficial effects of this utility model are as follows: Compared with the prior art, this utility model has a reasonable structural design. The power source is provided by a motor, which drives the hollow stirring shaft and the hollow transmission shaft to rotate synchronously. The hollow transmission shaft, as the core transmission component, transmits power to the rotating cleaning mechanism, causing it to rotate accordingly. The hollow transmission shaft has both transmission and media conveying functions. High-pressure cleaning fluid can be introduced into its interior. At the same time, cleaning water is transported to the cleaning nozzle through the internal channel of the hollow transmission shaft. The cleaning nozzle includes a first branch pipe and a second branch pipe. Cleaning nozzles are installed along the axial direction of the hollow transmission shaft corresponding to the position of each layer of the tower plate. The opening directions of the first branch pipe and the second branch pipe are respectively set towards the upper and lower plates of the tower plate, and the adjacent branch pipes are arranged in a staggered manner at 90° vertically. During the rotation of the hollow transmission shaft, the high-pressure cleaning fluid is directionally sprayed through the cleaning fluid spray holes of the first branch pipe and the second branch pipe, forming an all-round flushing of the deposits on the surface of the tower plate, achieving efficient cleaning.

[0013] Finally, nine rotating cleaning mechanisms are set from top to bottom on the hollow stirring shaft, and the rotating motion of the rotating cleaning mechanisms is used to achieve dynamic cleaning of each layer of tower plates.

[0014] This utility model integrates the synergistic effects of power transmission, media conveying and mechanical cleaning. Through the "dual-purpose" hollow drive shaft (which transmits torque and conveys cleaning water), it has a simple structure and can efficiently complete the cleaning and maintenance of the key components of the through-plate tower, ensuring the stable operation of the tower equipment. This makes the cleaning work highly efficient, easy to maintain, stable and practical.

[0020] See Figures 1 to 3 This utility model discloses an automatic cleaning device for a cross-flow plate tower, comprising a cylindrical body 1, a hollow drive shaft 2 vertically arranged inside the cylindrical body 1, a drive device arranged at the upper end of the hollow drive shaft 2, and a hollow stirring shaft 3 detachably arranged at the lower end of the hollow drive shaft 2. The hollow stirring shaft 3 is provided with a plurality of rotating cleaning mechanisms from top to bottom, each rotating cleaning mechanism including a plurality of cleaning nozzles, the cleaning nozzles including a first branch pipe 41 and a second branch pipe 42, the first branch pipe 41 and the second branch pipe 42 being staggered, the first branch pipe 41 being provided with a plurality of first cleaning liquid injection through holes, and the second branch pipe 42 being provided with a plurality of second cleaning liquid injection through holes;

[0021] The driving device drives the hollow transmission shaft 2 to rotate, and the hollow stirring shaft 3 is linked with the hollow transmission shaft 2. The hollow stirring shaft 3 is provided with multiple connection ports. One end of the first branch pipe 41 and the second branch pipe 42 are respectively fixed to the aligned connection ports by thread or by welding. The hollow stirring shaft 3 simultaneously drives the first branch pipe 41 and the second branch pipe 42 to rotate.

[0022] Preferably, the first branch pipe 41 and the second branch pipe 42 are staggered at 90°; the first cleaning fluid injection through-hole on the first branch pipe 41 is inclined downward at 45-75°; the second cleaning fluid injection through-hole on the second branch pipe 42 is inclined upward at 45-75°.

The hollow transmission shaft 2, as the core transmission component, transmits power to the rotating cleaning mechanism, causing it to rotate accordingly. The hollow transmission shaft 2 has both transmission and media conveying functions. High-pressure cleaning fluid can be introduced into its interior. At the same time, cleaning water is transported to the cleaning nozzle through the internal channel of the hollow transmission shaft 2. The cleaning nozzle includes a first branch pipe 41 and a second branch pipe 42. Cleaning nozzles are installed along the axial direction of the hollow transmission shaft 2 corresponding to the position of each tray.

During the rotation of the hollow transmission shaft 2, the high-pressure cleaning fluid is directionally sprayed through the cleaning fluid spray holes of the first branch pipe 41 and the second branch pipe 42, forming an all-round flushing of the deposits on the tray surface, achieving efficient cleaning.

[0030] Finally, nine rotating cleaning mechanisms are set from top to bottom on the hollow stirring shaft 3, and the rotating motion of the rotating cleaning mechanisms is used to achieve dynamic cleaning of each layer of tower plates.

Through the "dual-purpose" hollow drive shaft (which transmits torque and conveys cleaning water), it has a simple structure and can efficiently complete the cleaning and maintenance of the key components of the through-plate tower, ensuring the stable operation of the tower equipment. This makes the cleaning work highly efficient, easy to maintain, stable and practical.
