Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of tank production cleaning, in particular to a tank production internal spraying cleaning device. BACKGROUND

[0002] In the tank production process, the tank is mostly made of metal material and is welded into shape, and welding slag, welding tumor, splashes, welding agent residues and the like are left inside. If the inside is not cleaned, the sharp welding slag in the tank body will scratch the anticorrosive coating of the inner wall, thereby accelerating local corrosion and shortening the service life of the tank. At the same time, the welding agent residues may also react with the stored medium, polluting the medium or accelerating the wear of the inner wall.

[0003] At the same time, in the process of tank production, iron filings and burrs generated by metal cutting, mold lubricants used in the forming stage, rust-proof oil, and dust and impurities brought in during the assembly process will adhere to the tank wall or deposit at the tank bottom. For liquid storage tanks, these residues will block the subsequent pipelines and valves, or mix with the medium to affect the purity. For pressure tanks, granular residues may also wear the inner wall due to vibration during operation, increasing the risk of leakage. Therefore, the internal cleaning of the tank after production is a crucial process.

[0019] The present application has the following advantages:

[0020] The internal spraying cleaning equipment for tank production provided by the present application can adjust the longitudinal position of the cleaning mechanism through the lifting assembly, specifically, the worker rotates the handle to drive the threaded screw rod to rotate, the threaded sleeve moves along the screw rod, the storage seat is driven to ascend and descend along the through groove through the fixing frame, so that the position of the storage seat and the multi-dimensional spraying assembly in the tank body can be adjusted, different height tank bodies can be matched, and the cleaning blind area caused by insufficient height matching can be avoided.

[0021] The internal spraying cleaning equipment for tank production provided by the application, through the transverse moving assembly, in the process of cleaning the inside of the tank body, first, the cleaning liquid enters the first fixed pipe through the liquid inlet pipe and the hose, then flows into the first rotating pipe and enters the centrifugal seat, at this time, the centrifugal seat can drive the first rotating pipe to rotate along the sealing bearing in the first fixed pipe through the impact force of the water flow, and the first fixed pipe outer wall first bevel gear meshes with the second fixed pipe outer wall second bevel gear, under the linkage action of the first rotating pipe rotation, the second fixed pipe drives the spraying seat to make the circular motion in the X-axis direction along the sealing bearing on one side of the centrifugal seat, that is, the rotation direction forms an alternating angle with the centrifugal seat, when the spraying seat rotates, the third fixed pipe on the circumference thereof moves, and the second rotating pipe at the end of the third fixed pipe rotates independently under the combined action of the water flow reaction force and the centrifugal force, thereby the multi-dimensional spraying assembly forms the multi-dimensional rotation track of "centrifugal seat revolution, spraying seat rotation and nozzle independent rotation", effectively expands the cleaning area of the whole multi-dimensional spraying assembly to the inside of the tank body, and greatly reduces the generation of cleaning dead angles.

[0022] The internal spraying cleaning equipment for tank production provided by the application, through the multi-dimensional spraying assembly, when the cleaning liquid is delivered to the inside of the nozzle, the cleaning liquid can be sprayed from the three groups of second liquid spraying grooves opened on the outer wall of the nozzle, the cleaning liquid sprayed from the three groups of liquid spraying grooves can form a three-layer spraying net in a three-dimensional manner, thereby all kinds of stains such as slag, welding tumor, splashes, iron filings, mold lubricant residues on the tank wall and tank bottom can be flushed and covered in all directions without dead angles, since the three groups of second liquid spraying grooves are staggered distributed on the outer wall of the nozzle circumference, and the length gradually increases in the direction away from the second rotating pipe, cooperating with the independent rotation of the nozzle with the second rotating pipe and the multi-dimensional rotation of the spraying seat and the centrifugal seat, the three-layer spraying net can form a dynamic and superimposed spraying track, not only avoids the appearance of spraying gaps, but also covers different radial ranges through the cleaning liquid sprayed by the liquid spraying grooves of different lengths, realizes gradient flushing from the nozzle periphery to the tank wall edge, at the same time, the inner diameter of the nozzle gradually decreases in the direction away from the second rotating pipe, which can improve the pressure of the cleaning liquid when sprayed, enhance the impact and stripping capacity on stubborn stains, and effectively solve the problem of incomplete cleaning caused by the limited spraying range and uneven pressure of the traditional fixed spraying.

[0023] This invention provides an internal spray cleaning device for storage tank production. Through a spray pipe, when the pipe rotates to a vertically downward position, a movable ring plate inside the pipe, under the pressure of the liquid and the weight of the counterweight, overcomes the spring force, causing the counterweight to slide downwards and engage with a mating groove. At this time, the second spray hole in the middle of the counterweight aligns with and connects to the first spray hole at the end of the spray pipe. Because the inner diameter of the second spray hole is smaller than that of the first spray hole, the flow velocity of the cleaning liquid increases significantly when it passes through this point, further enhancing the spray pressure. This allows for a powerful impact on heavier impurities such as flux residue and iron filings deposited at the bottom of the tank. It effectively peels off and washes away stubborn deposits at the bottom of the tank, solving the problem of insufficient cleaning power of traditional spraying. When the spray pipe rotates with the nozzle to a non-vertical downward position, the counterweight will drive the movable ring plate to reset under the action of the spring force. The counterweight will disengage from the mating groove, and the cleaning liquid will be sprayed out completely from the first spray hole. Combined with the multi-dimensional rotation of the nozzle, it forms a wider spray coverage. This design of automatically adjusting the spray pressure and direction with the rotation of the spray pipe not only enhances the cleaning effect of key areas at the bottom of the tank, but also takes into account the spray coverage of other areas, meeting people's needs for cleaning stubborn impurities at the bottom of the tank.

Under the linkage action of the rotation of the first rotating pipe 23, the second fixed pipe 22 drives the spray seat 14 to do the circular motion in the X-axis direction along the sealing bearing 35 on one side of the centrifugal seat 21, that is, the rotation direction forms an alternating angle with the centrifugal seat 21. When the spray seat 14 rotates, the third fixed pipe 29 on the circumference thereof moves, and the second rotating pipe 30 at the end of the third fixed pipe 29 drives the spray head 25 to rotate independently under the combined action of the water flow reaction force and the centrifugal force, thereby forming the multi-dimensional rotation track of the multi-dimensional spray assembly of "the centrifugal seat 21 revolves, the spray seat 14 rotates, and the spray head 25 rotates independently", effectively expanding the cleaning area of the entire multi-dimensional spray assembly to the inside of the tank 1, and greatly reducing the generation of cleaning dead angles.

[0048] When the cleaning liquid is delivered to the inside of the spray head 25, the cleaning liquid can be sprayed out from the three groups of second liquid spraying grooves 28 opened on the outer wall of the spray head 25. The cleaning liquid sprayed out from the three groups of liquid spraying grooves can form a three-layer spray net in a three-dimensional manner, thereby being able to perform omnidirectional and dead-angle-free flushing and covering on various stains such as slag, weld tumor, splashes, iron filings, and residual mold lubricant on the tank wall and the tank bottom. Since the three groups of second liquid spraying grooves 28 are staggered on the circumferential outer wall of the spray head 25, and the lengths thereof gradually increase in the direction away from the second rotating pipe 30, in combination with the independent rotation of the spray head 25 with the second rotating pipe 30 and the multi-dimensional rotation of the spray seat 14 and the centrifugal seat 21, the three-layer spray net can form a dynamic and superimposed spraying track, which not only avoids the emergence of spraying gaps, but also covers different radial ranges through the cleaning liquid sprayed out from the liquid spraying grooves of different lengths, so as to realize gradient flushing from the periphery of the spray head 25 to the edge of the tank wall. At the same time, the inner diameter of the spray head 25 gradually decreases in the direction away from the second rotating pipe 30, which can improve the pressure of the cleaning liquid when sprayed out, enhance the impact and stripping capacity on stubborn stains, and effectively solve the problem of incomplete cleaning caused by the limited spraying range and uneven pressure of the traditional fixed spray.

[0049] For the spray pipe 26 arranged on one side of the spray head 25, when the spray pipe 26 is rotated to the vertical downward state, the movable ring plate 38 in the spray pipe 26 will overcome the elastic force of the spring 37 under the liquid pressure and the gravity of the counterweight 41 itself, thereby driving the counterweight 41 to slide downward and cooperate with the matching groove 40, at this time, the second spray hole 42 in the middle of the counterweight 41 is aligned and communicated with the first spray hole 39 at the end of the spray pipe 26, since the inner diameter of the second spray hole 42 is smaller than that of the first spray hole 39, the flow rate of the cleaning liquid flowing through this place will be significantly increased, the jet pressure is further enhanced, and strong impact can be formed on the heavy impurities such as flux residues and iron scraps deposited on the bottom of the tank 1, thereby effectively stripping and flushing away the stubborn deposits on the tank bottom, solving the problem of insufficient cleaning force of the traditional spray on the tank bottom, and when the spray pipe 26 is rotated with the spray head 25 to a non-vertical downward state, the counterweight 41 will drive the movable ring plate 38 to reset under the action of the elastic force of the spring 37, and the counterweight 41 is separated from the matching groove 40, at this time, the cleaning liquid is completely sprayed out of the first spray hole 39, and the multi-dimensional rotation of the spray head 25 forms more extensive spray coverage, this design of automatically adjusting the liquid pressure and direction with the rotation state of the spray pipe 26 not only strengthens the cleaning effect of the key area of the tank bottom, but also takes into account the spray coverage of other areas, meeting the cleaning needs of people for stubborn impurities on the bottom of the tank 1.

[0050] The above only describes the preferred embodiments of the present application and is not used to limit the present application, any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
