[0005] A tube bundle reactor inner wall cleaning device includes a first sponge storage tube, a second sponge storage tube, and a support rod. The first and second sponge storage tubes are respectively located on both sides of the support rod and are parallel to the support rod. The support rod is fixedly connected to the first and second sponge storage tubes by a snap fastener. A rotating pre-storage mechanism for pre-storing sponge bullets is provided below the first and second sponge storage tubes.

[0018] To further describe the technical features and effects of this utility model, the following description is provided in conjunction with the accompanying drawings and specific embodiments.

[0019] Reference Figures 1-5As shown, a tube bundle reactor inner wall cleaning device includes a first sponge storage tube 1, a second sponge storage tube 2, and a support rod 3. The first sponge storage tube 1 and the second sponge storage tube 2 are respectively arranged on both sides of the support rod 3 and are parallel to the support rod 3. The support rod 3 is fixedly connected to the first sponge storage tube 1 and the second sponge storage tube 2 by a buckle 4. A rotating pre-storage mechanism for pre-storing sponge bullets is provided below the first sponge storage tube 1 and the second sponge storage tube 2. An air chamber tube 5 is provided below the rotating pre-storage mechanism. A cleaning gun head 6 is provided below the air chamber tube 5. The outer walls of the air chamber tube 5 and the cleaning gun head 6 are fixedly connected to the support rod 3. An air inlet 20 is provided on the outer wall of the air chamber tube 5. A cylinder 7 is provided above the rotating pre-storage mechanism. The cylinder 7 is fixedly connected to the support rod 3. The movable end of the cylinder 7 faces downward and is connected to a movable push rod 8.

[0020] The rotating pre-storage mechanism includes a first pre-storage tube 9, a second pre-storage tube 10, and a rotating baffle 11. The rotating baffle 11 is arranged perpendicular to the axial direction of the support rod 3 and is rotatably connected to the axial direction of the support rod 3. The rotating baffle 11 is provided with a first blocking position 12, a first through hole 13, a second through hole 14, and a second blocking position 15 in sequence along the rotation direction. The first pre-storage tube 9 is located directly below the first through hole 13 and is connected to the rotating baffle 11. The second pre-storage tube 10 is located directly below the second through hole 14 and is connected to the rotating baffle 11.

[0021] To facilitate the alternating removal of sponge cartridges from the first sponge storage tube 1 and the second sponge storage tube 2 by the first pre-storage tube 9 and the second pre-storage tube 10, a rotating handle 25 is provided on one side above the support rod. The rotating handle 25 is set perpendicular to the support rod 3 and is axially rotatably connected to the support rod 3. A connecting rod 16 is provided below the rotating handle 25 and parallel to the support rod 3. The upper end of the connecting rod 16 is connected to the rotating handle 25, and the lower end of the connecting rod 16 is connected to the rotating auxiliary rod 17. The rotating auxiliary rod 17 is connected to the rotating bushing 18. The rotating bushing 18 is fitted onto the lower end of the support rod 3, and the upper end of the rotating bushing 18 is fixedly connected to the bottom of the rotating baffle 11.

[0022] The support rod 3 is also equipped with a handle 19 for stabilizing the entire cleaning device.

[0023] To increase grip comfort and stability, a rubber sheath (not shown) is fitted on the handlebar 19.

[0024] In order to control the air intake of the air intake nozzle 20 and the air intake of the cylinder 7, a first pneumatic switch valve 21 for controlling the air intake of the air intake nozzle 20 and a second pneumatic switch valve 22 for controlling the air intake of the cylinder 7 are provided on the support rod.

[0025] In order to make the sponge bullets more powerfully fired after loading, a sealing plate 23 is provided at the top of the inner side of the air chamber tube 5. The sealing plate 23 is connected to one side of the top of the air chamber tube 5 by a torsion spring 24.

[0026] When using this device to clean the reactor tube bundle, first connect the air inlet 20 to the external air source through the first pneumatic switch valve 21, and connect the cylinder 7 to the external air source through the second pneumatic switch valve 22.

[0027] Next, sponge bullets are loaded into both the first sponge storage tube 1 and the second sponge storage tube 2. The sponge bullets used in this invention are cylindrical, and their length can be adjusted according to actual needs to improve cleanliness and cleaning efficiency (e.g., 10cm, 12cm, 15cm, etc.). The sponge bullets are arranged sequentially in the first sponge storage tube 1 and the second sponge storage tube 2, with 10 bullets stored in each sponge storage tube. Assuming the initial state is that the first pre-storage tube 9 and the second pre-storage tube 10 are in the first state position, that is, the first pre-storage tube 9 is aligned with the first sponge storage tube 1, and the second pre-storage tube 10 is aligned with the air chamber tube 5, the second blocking position 15 of the rotating baffle 11 blocks the bottom of the second sponge storage tube 2, and the cylinder 7 is driven by the second pneumatic switch valve 22 to push the movable push rod 8 downward. The movable push rod 8 presses the sponge bullet in the second pre-storage tube 10 (assuming that the second pre-storage tube has been loaded with sponge bullets) downward. Under the action of pressure, the sealing plate 23 at the top of the air chamber tube 5 opens downward, and the sponge bullet is pressed into the air chamber tube 5. The movable push rod 8 retracts, and the sealing plate 23 springs back under the action of the torsion spring 24 to close the top of the air chamber tube 5. At this time, the air intake nozzle 20 is controlled by the first pneumatic switch valve 21 to introduce air, and the sponge bullet is fired from the cleaning gun head 6 (thus completing one sponge bullet firing).

[0028] In the first state position, the sponge bullet in the first sponge storage tube 1 falls freely into the first pre-storage tube 9 under the action of gravity (the lower diameter of the first pre-storage tube 9 and the second pre-storage tube 10 is slightly smaller than the diameter of the sponge bullet, so that it will not fall freely out of the first pre-storage tube 9 and the second pre-storage tube 10, but it can be pressed out by the movable push rod 8). Then, the rotating handle 25 is turned, and the connecting rod 16 drives the rotating bushing 18 to rotate to the second state position, that is, the lower end of the first pre-storage tube 9 is aligned with the upper end of the air chamber tube 5 (that is, the first through hole 13 and the air chamber tube 5 are aligned), and the upper end of the second pre-storage tube 10 is aligned with the lower end of the second sponge storage tube 2 (that is, the second through hole 14 and the second sponge storage tube 2 are aligned). The first blocking position 12 of the rotating baffle 11 blocks the bottom of the first sponge storage tube 1, and the sponge bullet in the second sponge storage tube 2 falls freely into the second pre-storage tube 10 under the action of gravity. Meanwhile, we can control the cylinder 7 to drive the movable push rod 8 downward through the second pneumatic switch valve 22. The movable push rod 8 presses the sponge bullet in the first pre-storage tube 9 downward. Under the pressure, the sealing plate 23 at the top of the air chamber tube 5 opens downward again, and the sponge bullet is pressed into the air chamber tube 5. The movable push rod 8 retracts, and the sealing plate 23 springs back under the action of the torsion spring 24 to close the top of the air chamber tube 5. At this time, the air intake nozzle 20 is controlled by the first pneumatic switch valve 21 to allow air to enter, and the sponge bullet is fired again from the cleaning gun head 6. This cycle is repeated to replenish the sponge bullets and fire continuously, greatly improving work efficiency.

[0029] The above embodiments are not intended to limit the present invention in any way. Any technical solutions obtained by equivalent substitution or equivalent transformation shall fall within the protection scope of the present invention.
