Description

Technical Field

[0001] This invention relates to the field of pipe cleaning, specifically a submersible pipe cleaning device and its cleaning method. Background Technology

[0002] Currently, in the field of pipe cleaning, the common method for batch cleaning of pipe fittings is tank cleaning. This involves placing a batch of pipe fittings into a cleaning tank equipped with an ultrasonic device to perform ultrasonic cleaning. However, this method has a drawback: due to the stacking of the pipe fittings within the cleaning tank, the stacking state needs to be constantly changed during cleaning to achieve effective cleaning; otherwise, the stacked pipe fittings result in poor cleaning. To address this technical problem, a utility model entitled "An Ultrasonic Cleaning Tank for Degreasing Titanium Pipes" was published in Chinese patent literature (CN201012362Y, authorized on January 30, 2008). This utility model includes a cleaning tank, a heater disposed within the cleaning tank, an ultrasonic transducer disposed inside the cleaning tank, and a turning mechanism disposed within the cleaning tank. The turning mechanism includes a drive mechanism and teeth connected to the drive mechanism. Its main function is to slowly turn the bundled titanium pipes while cleaning, thereby improving the cleaning effect. In addition, a scheme involving a circulating pump in the cleaning tank was disclosed to improve the flow of the cleaning fluid and further enhance the cleaning effect. While this scheme improves pipe cleaning, it still cannot completely prevent pipe stacking, and the process of turning over the pipes can easily cause mutual squeezing and wear. Furthermore, because the circulating pump only circulates the cleaning fluid in the cleaning tank, the inner wall of the pipe is not effectively rinsed, resulting in a poor overall cleaning effect for the pipes. Therefore, improvements are needed to the existing tank-type pipe cleaning structure. Summary of the Invention

[0003] To overcome the above-mentioned shortcomings, the purpose of this invention is to provide a submersible pipe cleaning device and its cleaning method, thereby solving the technical problem that existing similar tank-type pipe cleaning devices suffer from poor cleaning results due to pipe stacking and poor fluid flow within the pipes. This objective is achieved through the following technical solution.

[0004] A submersible pipe cleaning device includes a crane, a cleaning tank, and a pipe support frame. The crane is used to hoist the pipe support frame into the cleaning tank. The key structural feature is that the length of the cleaning tank corresponds to the length of the pipe to be cleaned. The pipe support frame has vertically spaced pipe support positions on one side. The pipe support frame is vertically hoisted into the cleaning tank, and when in place, it is positioned within the tank. The cleaning tank contains a pipe clamping mechanism to clamp the pipes on the pipe support frame. A movable pipe connection device is provided at one end of the cleaning tank. The movable pipe connection device includes a movable... The platform and the pipe connection section that move with the mobile platform correspond to the axial direction of the pipe fittings inside the cleaning tank. The pipe connection section is fixedly equipped with pipe sealing joints corresponding to one end of each pipe fitting on the pipe rack inside the cleaning tank. These pipe sealing joints merge to connect to external cleaning pipelines. When the pipe clamping mechanism clamps the pipe fittings and the mobile platform moves the pipe connection section to one end, the sealing pipe joint of the pipe connection section inserts into the pipe end of the corresponding pipe fitting on the pipe rack to form a sealed pipe connection. When the mobile platform moves the pipe connection section to the other end, the sealing pipe joint of the pipe connection section separates from the pipe end of the corresponding pipe fitting. With this structure, the pipe fittings after the pipe rack is placed in the cleaning tank are spaced vertically, preventing stacking and facilitating the cleaning operation. Furthermore, after the pipe rack is placed in the cleaning tank, the mobile pipe connection device, in conjunction with the pipe clamping mechanism, enables the connection of external cleaning pipelines to the pipe ends, facilitating effective high-pressure flushing of the pipe fittings and improving the cleaning effect. The cleaning equipment is equipped with several cleaning tanks arranged side by side. Each cleaning tank has a movable pipe connection device at one end. A circulation pump is installed in the cleaning pipeline connected to the pipe connection of each movable pipe connection device. The inlet of the circulation pump is connected to the inside of the cleaning tank, thus creating a circulating cleaning effect on the pipes. This structure achieves circulating cleaning of the inner wall of the pipes and allows for repeated cleaning of the pipes as needed. Different cleaning solutions can be used in different cleaning tanks to achieve different cleaning effects, thus broadening its applicability.

[0005] The mobile platform includes a horizontally limited electric trolley, which fixes the pipe connection. This structure, as an implementation of the mobile platform, is relatively convenient to use.

[0006] The mobile platform includes an electrically operated lifting bracket, the bracket portion of which is fixed to the electric trolley. The lifting portion of the electrically operated lifting bracket is connected to the pipe joint. When the lifting portion of the electrically operated lifting bracket descends to its final position, the pipe sealing joint of the pipe joint aligns with the pipe end of the fitting inside the cleaning tank. When the lifting portion of the electrically operated lifting bracket rises to its final position, the pipe joint detaches from the cleaning tank. This structure facilitates the removal of the pipe joint from the cleaning tank for replacement or maintenance.

[0007] The pipe clamping mechanism includes clamping assemblies distributed on both sides of the pipe fitting in the cleaning tank. Each clamping assembly includes an electric cylinder, a roller, a clamping wheel, and a synchronous gear. The synchronous gear is shaft-fixed to the lower end of the roller and rotatably positioned at the bottom of the cleaning tank. Two synchronous gears in the two clamping assemblies mesh to rotate synchronously. The top of the roller is rotatably positioned on a support plate, which is fixed to the top of the cleaning tank. The roller is shaft-fixed with an eccentric clamping wheel, i.e., the axle of the clamping wheel is eccentrically set with the axis of the roller. The axle of the clamping wheel passes through an arc-shaped sliding hole at the top of the support plate and is hinged to one end of the push rod of the electric cylinder. The arc-shaped sliding hole is adapted to the eccentric swing of the clamping wheel relative to the roller. The cylinder seat end of the electric cylinder is rotatably positioned on the support plate. In the initial state, a clamping space for placing the pipe fitting is formed between the clamping wheels in the two clamping assemblies. When the electric cylinders of the two clamping assemblies push the push rod to drive the clamping wheel and roller to rotate, the clamping wheels on both sides rotate in opposite directions and clamp the pipe fitting relative to each other. This structure enables effective clamping of pipe fittings on one side of the pipe rack, and through the aforementioned synchronous gears, it achieves synchronous clamping of clamping wheels on both sides, resulting in more stable and reliable clamping of pipe fittings.

[0008] The cleaning equipment includes a purge tank with the same structure as the cleaning tank, arranged side by side. The purge tank contains the same pipe clamping mechanism and movable pipe connection device as the cleaning tank. The cleaning pipeline connected to the pipe connection of the movable pipe connection device is connected to an external high-pressure air pump. This structure facilitates the purge of the inner wall of the cleaned pipe fittings.

[0009] The inner wall of the purging tank is equipped with a heating plate that heats the outer wall of the pipe fittings on the pipe rack. The bottom of the purging tank is equipped with a drain port connected to an external drain pump. This structure further improves the purging and drying effect of the pipe fittings.

[0010] The inner side of the cleaning tank is equipped with an ultrasonic transducer plate for ultrasonic cleaning of the pipe fittings on the pipe rack, and / or a heating device for heating the cleaning fluid in the cleaning tank. This structure enables ultrasonic cleaning of the pipe fittings, and the heating further enhances the cleaning effect.

[0011] The pipe support frame has vertically spaced pipe support positions (302) on both sides. The pipe clamping mechanism (5) includes a left clamping deformation block, a middle clamping block, and a right clamping deformation block. One end of each of the left clamping deformation block, the middle clamping block, and the right clamping deformation block is connected to the pipe connection part of the movable pipe connection device. After connection, the left clamping deformation block is located on one side of the cleaning tank, the right clamping deformation block is located on the other side of the cleaning tank, and the middle clamping block is located in the middle position of the two pipe fittings on the pipe support frame inside the cleaning tank. The other end of each of the left clamping deformation block and the right clamping deformation block is connected to the cleaning tank. A fixed structure is formed on one side of the groove; when the pipe rack is placed in the cleaning groove, and the moving pipe connection device moves the pipe connection towards the end of the pipe fitting, the middle clamping block enters the middle position of the pipe fittings on both sides of the pipe rack and forms contact with the pipe fittings on both sides. The left clamping deformation block and the right clamping deformation block are pushed towards the middle clamping block by the pipe connection to form a convex deformation and clamp the pipe fittings on both sides of the pipe rack. The clamping state of the pipe fitting is before the pipe sealing joint of the pipe connection is inserted into the sealing pipe fitting end, or the clamping state of the pipe fitting is synchronous with the pipe sealing joint of the pipe connection being inserted into the sealing pipe fitting end.

[0012] The cleaning method of this submersible pipe cleaning equipment is as follows: pipes are vertically arranged on the pipe rack. The pipe rack is hoisted into the cleaning tank by the crane and positioned. The pipe clamping mechanism clamps and fixes the pipes on the pipe rack. The moving platform of the movable pipe connection device is controlled to move the pipe connection towards the pipe end of the pipe until the pipe sealing joint of the pipe connection is inserted into the pipe end of the pipe to form a seal. The circulation pump of the cleaning pipeline is turned on, and the cleaning fluid in the cleaning tank is pumped into the pipe to form a flush. After cleaning, the circulation pump and ultrasonic transducer are turned off. The movable pipe connection device is controlled to reset and disengage from the pipe end of the pipe. The crane lifts the pipe rack out of the cleaning tank and transports it to the pipe unloading station, thus completing the cleaning operation.

[0013] This invention solves the disadvantages of stacking pipe fittings in a cleaning tank for cleaning. The tank cleaning method also effectively rinses the inner wall of the pipe fittings, resulting in higher cleaning efficiency and better effect. It is suitable for use as a tank cleaning structure for various types of pipe fittings, or as an improvement on similar cleaning structures. Attached Figure Description

[0026] The present invention will now be further described with reference to the accompanying drawings.

[0027] like Figures 1-3 , Figures 5-8As shown, the submersible pipe cleaning equipment includes a crane, a pipe rack 3, and several cleaning tanks 1 arranged side by side. The inner side of the cleaning tank is equipped with an ultrasonic vibrating plate 2 for ultrasonic cleaning of the pipes on the pipe rack, and / or a heating device 10 is provided on the bottom surface of the cleaning tank. The crane is used to hoist the pipe rack into the cleaning tank. The length of the cleaning tank corresponds to the length of the pipes 4 to be cleaned. The top of the pipe rack is equipped with lifting lugs 301, and one side of the pipe rack is equipped with vertically spaced pipe support positions 302. The pipe rack is vertically hoisted into the cleaning tank. When the hoist is in place, the pipe rack is positioned relative to the cleaning tank by the limiting action of the hoisting equipment. Alternatively, the bottom of the pipe rack can be positioned by a concave-convex fit with the bottom of the cleaning tank. Each cleaning tank is equipped with a pipe clamping mechanism 5 to clamp the pipe fittings on the pipe rack. The pipe clamping mechanism includes clamping components distributed on both sides of the pipe fittings in the cleaning tank. Each clamping component includes an electric cylinder (502), a roller (503), a clamping wheel (504), and a synchronous gear (505). The synchronous gear is shaft-fixed to the lower end of the roller and rotates to be positioned at the bottom of the cleaning tank. Two synchronous gears in the two clamping components mesh to rotate synchronously. The top of the roller is rotated to be positioned on a support plate, and the support plate is fixed to the top of the cleaning tank. The roller is shaft-fixed with an eccentric mechanism. The clamping wheel, i.e., the axle (5041) of the clamping wheel is eccentrically set with the axis of the roller shaft. The axle of the clamping wheel passes through the arc-shaped sliding hole (506) at the top of the support plate and is hinged to one end of the push rod of the electric cylinder. The arc-shaped sliding hole is adapted to the eccentric swing of the clamping wheel relative to the roller shaft. The cylinder seat end of the electric cylinder is rotated and positioned on the support plate. In the initial state, a clamping space for placing the pipe is formed between the clamping wheels in the two clamping assemblies. When the electric cylinders of the two clamping assemblies push the push rod to drive the clamping wheel and the roller shaft to rotate, the clamping wheels on both sides rotate synchronously in opposite directions and clamp the pipe relative to each other.

[0028] Each of the aforementioned cleaning tanks 1 is equipped with a movable pipe connection device at one end. The movable pipe connection device includes a movable platform and a pipe connection part 6 that moves with the movable platform. The moving direction of the movable platform corresponds to the axial direction of the pipe fittings 4 inside the cleaning tank. The pipe connection part is fixedly equipped with a pipe sealing joint 601 that corresponds to one end of each pipe fitting on the pipe rack inside the cleaning tank. The pipe sealing joints merge and connect to the external cleaning pipeline 8. When the pipe clamping mechanism clamps the pipe fitting, and the movable platform moves the pipe connection part to one end, the sealing pipe joint of the pipe connection part is inserted into the pipe end of the corresponding pipe fitting on the pipe rack to form a sealed pipe connection. When the movable platform moves the pipe connection part to the other end, the sealing pipe joint of the pipe connection part separates from the pipe end of the corresponding pipe fitting. The aforementioned movable platform includes a horizontally limited electric trolley 7 and an electric lifting bracket 701. The electric lifting mechanism is an electric cylinder lifting mechanism or a motor worm gear lifting mechanism, which includes a bracket part and a lifting part. The bracket part of the electric lifting bracket is fixed to the electric trolley, and the lifting part of the electric lifting bracket is connected to the aforementioned pipe connection part. When the lifting section of the electric lifting bracket descends to its final position, the pipe sealing joint of the pipe connection aligns with the pipe end of the fitting inside the cleaning tank. When the lifting section of the electric lifting bracket rises to its final position, the pipe connection detaches from the cleaning tank, facilitating replacement or maintenance. The cleaning pipeline connected to the external pipe connection of the movable pipe connection device is equipped with a circulation pump. The inlet of the circulation pump is connected to the inside of the cleaning tank, meaning the cleaning fluid in the tank circulates and cleans the fittings.

[0029] Furthermore, the pipe cleaning equipment can also be equipped with a purge tank that is parallel to and structurally identical to the aforementioned cleaning tank. The purge tank contains the same pipe clamping mechanism 5 and movable pipe connection device as the cleaning tank. The cleaning pipeline 8 connected to the pipe connection part 6 of the movable pipe connection device is connected to an external high-pressure air pump. This enables the purge and drying operation of the cleaned pipe fittings. The inner wall of the purge tank can also be equipped with a heating plate that heats the outer wall of the pipe fittings on the pipe rack. The bottom of the purge tank has a drain outlet connected to an external drain pump.

[0030] like Figure 4 As shown, the pipe rack 3 of the cleaning equipment can also be provided with vertically spaced pipe support positions 302 on both sides. Based on this scheme, such as Figures 9-11As shown, the pipe clamping mechanism in the cleaning tank is modified as follows: The pipe clamping mechanism includes a left clamping deformation block 507, a middle clamping block 508, and a right clamping deformation block 509. One end of each of the left clamping deformation block, the middle clamping block, and the right clamping deformation block is connected to the pipe connection part 6 of the movable pipe connection device. After connection, the left clamping deformation block is located on one side of the cleaning tank, the right clamping deformation block is located on the other side of the cleaning tank, and the middle clamping block is located in the middle position of the two pipe fittings 4 on the pipe rack inside the cleaning tank. The other end of each of the left clamping deformation block and the right clamping deformation block is fixed to the corresponding side inside the cleaning tank. When the pipe rack is placed in the cleaning tank and the moving pipe connection device moves the pipe connection towards the end of the pipe fitting, the middle clamping block enters the middle position of the pipe fittings on both sides of the pipe rack and forms contact with the pipe fittings on both sides. The left clamping deformation block and the right clamping deformation block are pushed towards the middle clamping block by the pipe connection to form a convex deformation and clamp the pipe fittings on both sides of the pipe rack. The clamping state of the pipe fitting is before the pipe sealing joint 601 of the pipe connection is inserted into the sealing pipe fitting end, or the clamping state of the pipe fitting is synchronized with the insertion of the pipe sealing joint of the pipe connection into the sealing pipe fitting end.

[0031] The cleaning method of the submersible pipe cleaning equipment is as follows: pipe fittings 4 are vertically arranged on the pipe rack 3. The pipe rack is hoisted into the cleaning tank 1 by a crane and positioned. The pipe fittings on the pipe rack are clamped and fixed by the pipe clamping mechanism 5. The moving platform of the moving pipe connection device is controlled to move the pipe connection part 6 toward the pipe end of the pipe fitting until the pipe sealing joint 601 of the pipe connection part is inserted into the pipe end of the pipe fitting to form a seal. The circulation pump 9 and ultrasonic transducer 2 of the cleaning pipeline 8 are turned on. The circulation pump pumps the cleaning liquid in the cleaning tank into the pipe fitting under high pressure to form a flush. The ultrasonic transducer performs ultrasonic cleaning on the inner and outer walls of the pipe fitting. After cleaning, the circulation pump and ultrasonic transducer are turned off. The moving pipe connection device is controlled to reset and disengage from the pipe end of the pipe fitting. The pipe rack is lifted out of the cleaning tank by the crane and transported to the pipe unloading station, thus completing the cleaning operation. If pipe purging is required, the pipe rack is hoisted into the purging trough using a crane. The pipe sealing joint of the movable pipe connection device is controlled to seal the pipe end in the same way. The high-pressure air pump is then turned on to achieve the purging and drying operation of the inner wall of the pipe.

[0032] The above description is intended to illustrate the technical means of the present invention and is not intended to limit the scope of the invention. Any obvious improvements or substitutions made to the present invention by those skilled in the art based on existing common knowledge also fall within the protection scope of the claims of the present invention.
