DETAILED DESCRIPTION

[0013] In order to further describe the technical features and effects of the present invention, the present invention is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0014] Reference Figure 1-Figure 5As shown, a tube bundle reactor inner wall cleaning device comprises 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, and the support rod 3 is fixedly connected to the first sponge storage tube 1 and the second sponge storage tube 2 through 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 cavity tube 5 is provided below the rotating pre-storage mechanism, a cleaning gun head 6 is provided below the air cavity tube 5, the outer side walls of the air cavity tube 5 and the cleaning gun head 6 are both fixedly connected to the support rod 3, an air inlet nozzle 20 is provided on the outer side wall of the air cavity tube 5, and a cylinder 7 is provided above the rotating pre-storage mechanism, the cylinder 7 is fixedly connected to the support rod 3, and the movable end of the cylinder 7 faces downward and is connected to a movable push rod 8.

[0015] Among them, the rotating pre-deposit mechanism includes a first pre-deposit tube 9, a second pre-deposit 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 axially rotatably connected to the support rod 3, and 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-deposit tube 9 is arranged directly below the first through hole 13 and is connected to the rotating baffle 11, and the second pre-deposit tube 10 is arranged directly below the second through hole 14 and is connected to the rotating baffle 11.

[0016] In order to facilitate the first pre-storage tube 9 and the second pre-storage tube 10 to alternately take out the sponge bullets from the first sponge storage tube 1 and the second sponge storage tube 2, a rotating handle 25 is provided on one side above the support rod. The rotating handle 25 is arranged 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 rotation auxiliary rod 17. The rotation auxiliary rod 17 is connected to the rotating shaft sleeve 18. The rotating shaft sleeve 18 is sleeved on the lower 3 ends of the support rod, and the upper end of the rotating shaft sleeve 18 is fixedly connected to the bottom of the rotating baffle 11.

[0017] A handle 19 is also provided on the support rod 3 for stabilizing the entire cleaning device.

[0018] In order to increase the comfort and stability of the grip, a rubber sheath tube (not shown) is sleeved on the handle 19.

[0019] In order to control the air intake of the air intake nozzle 20 and 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 cylinder 7 are provided on the support rod.

[0020] In order to allow the sponge bullet to be ejected more powerfully after loading, a sealing plate 23 is provided at the top inner side of the air cavity tube 5 , and the sealing plate 23 is connected to one side of the top of the air cavity tube 5 through a torsion spring 24 .

[0021] When the device is used to clean the reactor tube bundle, the air inlet nozzle 20 is first connected to the external air source through the first pneumatic switch valve 21 , and the air cylinder 7 is connected to the external air source through the second pneumatic switch valve 22 .

[0022] Next, sponge bullets are loaded into the first sponge storage tube 1 and the second sponge storage tube 2. The sponge bullets used in the present invention are cylindrical, and the length can be adjusted according to actual needs, with the main purpose of improving cleanliness and cleaning efficiency (for example, 10 cm, 12 cm, 15 cm, etc.). The sponge bullets are connected to each other in the first sponge storage tube 1 and the second sponge storage tube 2 and arranged in sequence, with 10 sponge bullets stored in each sponge storage tube. Assume that in the initial state, 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 cavity 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 controlled by the second pneumatic switch valve 22 to drive the movable push rod 8 to push 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 a sponge bullet) downward. Under the action of pressure, the sealing plate 23 at the top of the air cavity tube 5 opens downward, and the sponge bullet is pressed into the air cavity tube 5. The movable push rod 8 retracts, and the sealing plate 23 rebounds under the action of the torsion spring 24 to close the top of the air cavity tube 5. At this time, the air intake nozzle 20 is controlled by the first pneumatic switch valve 21 to intake air, and the sponge bullet is ejected from the cleaning gun head 6 (a sponge bullet is ejected once).

[0023] In the first state position, the sponge bullet in the first sponge storage tube 1 freely falls into the first pre-storage tube 9 under the action of gravity (the lower calibers of the first pre-storage tube 9 and the second pre-storage tube 10 are slightly smaller than the diameter of the sponge bullet so that it will not freely escape from the first pre-storage tube 9 and the second pre-storage tube 10, but can be pressed out by the movable push rod 8), then, the rotating handle 25 is rotated, and the connecting rod 16 drives the rotating sleeve 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 cavity tube 5 (that is, the first through hole 13 is aligned with the air cavity tube 5), 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 is aligned with the second sponge storage tube 2), and 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 freely falls into the second pre-storage tube 10 under the action of gravity. At the same time, we can control the cylinder 7 through the second pneumatic switch valve 22 to drive the movable push rod 8 to push downward, and the movable push rod 8 presses the sponge bullet in the first pre-storage tube 9 downward. Under the action of pressure, the sealing plate 23 at the top of the air cavity tube 5 opens downward again, and the sponge bullet is pressed into the air cavity tube 5. The movable push rod 8 retracts, and the sealing plate 23 rebounds under the action of the torsion spring 24 to close the top of the air cavity tube 5. At this time, the air intake nozzle 20 is controlled by the first pneumatic switch valve 21 to intake air, and the sponge bullet is ejected from the cleaning gun head 6 again. This cycle is repeated, the sponge bullets are replenished alternately, and continuous shooting is performed, which greatly improves work efficiency.

[0024] The above embodiments do not limit the present invention in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation shall fall within the protection scope of the present invention.
