Description

Technical Field

[0001] This utility model relates to the field of pipe cleaning equipment, and is an online filter pipe cleaning platform. Background Technology

[0002] In the existing field of pipe cleaning, pipe cleaning platforms are platform devices used to support or transport pipes and recover the cleaning fluid after cleaning. These devices have cleaning equipment at one or both ends to rinse the inner wall of the pipe with cleaning fluid or use brushes to clean it. For example, Chinese patent publication number CN218460345U, published on February 10, 2023, entitled "Pipe Cleaning Platform Liquid Recovery Device," discloses a platform for recovering cleaning fluid after pipe cleaning. Another example is Chinese patent publication number CN218283021U, published on January 13, 2023, entitled "Pipe Cleaning Platform," which discloses a cleaning platform with a transverse conveyor chain for convenient automatic transverse transport and cleaning of pipes. The above combined structure can achieve good pipe cleaning and fluid recovery, but it still has the following shortcomings: 1. Direct recovery of the cleaning fluid after pipe cleaning results in excessive amounts of grease and impurities, placing high demands on the filtration system in the circulating fluid tank. Furthermore, relying solely on the filtration system in the circulating fluid tank often fails to meet long-term and complex filtration requirements, necessitating frequent maintenance and replacement, leading to significant costs and inconvenience, time, and labor. 2. Using a transverse chain conveyor as the support system for the pipe cleaning platform results in a large size and weight, making installation and maintenance inconvenient. The fixed installation position also makes it difficult to adjust the support spacing according to pipe length, further complicating adjustment and use. Therefore, improvements to the existing pipe cleaning platform are needed. Summary of the Invention

[0003] To overcome the aforementioned shortcomings, the purpose of this utility model is to provide an online filter pipe cleaning platform, thereby solving the technical problems of existing similar pipe fitting conveying devices being structurally complex, inconvenient to install and use, and occupying a large space. This objective is achieved through the following technical solution.

[0004] An online filter tube cleaning platform includes a tube cleaning platform, a collection tray, and a circulating liquid tank. The collection tray, located above the cleaning platform, collects the cleaning fluid after tube cleaning. The circulating liquid tank is located at the bottom of the platform support, and the cleaning fluid in the collection tray flows into the circulating liquid tank. The key structural feature is that the bottom of the collection tray has a guide channel with a length not less than that of the tube. Filter media and oil-absorbing medium are laid flat along the entire length of the guide channel. A return channel is located at the top of the circulating liquid tank, and the end of the guide channel connects to the return channel, which contains filter media. By adding filter media and oil-absorbing medium to the guide channel, online filtration is effectively achieved through flow guidance, significantly reducing the filtration pressure in the subsequent circulating liquid tank. Frequent maintenance of the circulating liquid tank's filtration system is unnecessary; only the filter media and oil-absorbing medium in the guide channel need to be replaced or cleaned. Operation and maintenance are convenient, quick, and cost-effective. Furthermore, the continuous guide channel and filtration structure design accommodate cleaning fluid flow from various tube lengths, making filtration operations convenient.

[0005] The filter media in the guide channel and return channel is stainless steel mesh, and the oil-absorbing medium is any one or more combinations of quartz sand, walnut shells, anthracite, and PP oil-absorbing felt. The stainless steel mesh is laid flat on top of the oil-absorbing medium. This structure is a specific implementation structure of filter media and oil-absorbing medium, which is simple in structure and has good filtration and oil absorption effects.

[0006] The collection tray is equipped with a flow divider plate, with recessed guide grooves formed on both sides of the flow divider plate. The flow divider plate and the guide grooves are integral and welded to the collection tray. This structure makes the collection tray relatively stable and suitable for diverting and guiding flow in multi-pipe cleaning.

[0007] Above the pipe cleaning platform are several sets of transfer plate assemblies that synchronously support the pipes to be cleaned. Each transfer plate assembly includes a parallel front transfer plate and a rear transfer plate. The upper edges of both the front and rear transfer plates form a wavy pipe conveying surface. The crests and troughs of the front and rear transfer plate's pipe conveying surfaces are staggered along the pipe conveying direction. The front transfer plate is fixed relative to the pipe cleaning platform, while the rear transfer plate is connected to a lifting mechanism for vertical movement. When the rear transfer plate moves up and down, the pipe conveying surfaces of both the front and rear transfer plates alternately support the pipes. The pipes are rolled along the sloping surface from crest to trough in the pipe conveying surface. Each cycle of the rear transfer plate's vertical movement corresponds to one workstation for the pipe. This structure simplifies installation, reduces workstation space requirements, provides stable, reliable, and efficient lateral pipe conveying, and is water- and stain-resistant with a long service life.

[0008] The front transfer plate is fixed to the pipe cleaning platform via a slide rail assembly A. The slide rail assembly A includes a pair of guide rails A arranged along the length of the pipe on the pipe cleaning platform. A sliding seat is installed within each guide rail A, and the sliding seat is fixed to the front transfer plate. The front transfer plate is also equipped with a locking element that, when slid into position, locks with the side of the guide rail A. This structure allows the front transfer plate to easily slide and adjust its position along the guide rails A, thereby meeting the conveying requirements of different pipe lengths.

[0009] The rear transfer plate is fixed to the elevator via a slide rail assembly B. The slide rail assembly B includes a pair of guide rails B parallel to the slide rail assembly A. A sliding seat is provided within each guide rail B, and the sliding seat is fixed to the rear transfer plate. The rear transfer plate is also equipped with a locking element that locks with the side of the guide rails B when it slides into position. This structure allows the rear transfer plate to easily slide and adjust its position along the guide rails B, thus meeting the conveying requirements for different pipe lengths.

[0010] The sliding seat is a roller seat with a vertical strip-shaped sliding hole. The roller inside the roller seat is integrated with a bolt, which slides vertically into the strip-shaped sliding hole. After sliding into position, the bolt is locked in place by a nut. The locking element is a bolt seat with a bolt hole, which is tightened by hand-tightening a bolt to abut against the top side of the corresponding guide rail to form a locking mechanism. This structure allows for vertical adjustment of the sliding seat, thereby adjusting the height of the front and rear transfer plates. The locking element secures the sliding seat along guide rail A or after it has slid into position.

[0011] The lifting platform includes a motor, a transmission chain, a synchronous shaft, a screw jack, and a spiral bevel gear steering box. The motor is fixed to the pipe cleaning platform. Screw jacks are evenly distributed below guide rail B, and the guide rail B is fixed to the lifting top rod of the screw jack. The casing of the screw jack is fixed to the pipe cleaning platform. Screw jacks located below the same guide rail B are synchronously driven by synchronous shafts. The synchronous shaft between a pair of adjacent screw jacks is connected to the spiral bevel gear steering box. The spiral bevel gear steering boxes below guide rails on both sides are connected by synchronous shafts to achieve synchronous rotation. All screw jacks move synchronously. One synchronous shaft integrates a sprocket, which is connected to the drive wheel of the motor output shaft via a transmission chain. This structure enables the synchronous lifting of all rear transfer plates.

[0012] The front transfer plate has rollers at the troughs of its pipe conveying surface to provide rolling support for the pipe fittings at those troughs. This structure allows the front transfer plate and / or the rear transfer plate to adapt to the rotation of the pipe fittings in the workstation.

[0013] This utility model features a compact overall structure, incorporating cleaning fluid reflux filtration and pipe lateral movement support. The filter structure is easy to replace, maintain, and clean, reducing the frequency of maintenance of the filtration system within the circulating fluid tank and effectively lowering maintenance costs. The pipe lateral movement conveying structure is simple to install and requires minimal workspace. The pipe lateral movement conveying is stable, reliable, and efficient, and is water- and dirt-resistant with a long service life. It is suitable as a pipe cleaning platform for various pipe processing equipment or as a structural improvement of similar pipe cleaning platforms. Attached Figure Description

[0018] The present invention will now be further described with reference to the accompanying drawings.

[0019] like Figures 1-3 As shown, the online filter-type pipe cleaning platform includes a pipe cleaning platform 1, a collection tray 2, and a circulating liquid tank 5. A collection tray for collecting cleaning fluid after pipe cleaning is located above the pipe cleaning platform, and a circulating liquid tank is located at the bottom of the platform support. A flow divider 201 is located near the bottom of the collection tray, with recessed guide channels 202 formed on both sides of the flow divider. The flow divider and guide channels are integral and welded to the collection tray. The length of the guide channel is not less than the length of the pipe. Filter media 3 and oil-absorbing medium 4 are laid flat along the entire length of the guide channel. The filter media is stainless steel mesh, and the oil-absorbing medium is any one or a combination of quartz sand, walnut shells, anthracite, and PP oil-absorbing felt. A return channel 501 is located at the top of the circulating liquid tank, and the end of the guide channel leads into the return channel. The return channel is laid flat with the same filter media and oil-absorbing medium as described above, thus achieving secondary filtration or serving as an extension and supplementary filtration for the guide channel.

[0020] Above the aforementioned pipe cleaning platform 1, there are several sets of transfer plate assemblies that provide synchronous support for the pipes to be cleaned. The transfer plate assembly includes a front transfer plate 6 and a rear transfer plate 7 arranged in parallel. The upper edges of both the front and rear transfer plates form a wavy pipe conveying surface. The crests and troughs of the pipe conveying surface of the front transfer plate and the crests and troughs of the pipe conveying surface of the rear transfer plate are staggered along the pipe conveying direction. The front transfer plate is fixed relative to the pipe cleaning platform, and the rear transfer plate is connected to a lifting machine and moves up and down. When the rear transfer plate moves up and down, the pipe conveying surfaces of the front and rear transfer plates provide alternating support for the pipes. The pipes are rolled along the sloping surface from the crest to the trough in the pipe conveying surface. Each time the rear transfer plate completes one cycle of lifting and lowering, the pipe passes through one workstation.

[0021] The aforementioned front transfer plate 6 is fixed to the pipe cleaning platform 1 via a slide rail assembly A. The slide rail assembly A includes a pair of guide rails A8 arranged along the length of the pipe on the pipe cleaning platform. A sliding seat with sliding engagement is provided within the guide rails A, and this sliding seat is fixed to the front transfer plate. The front transfer plate is fixedly equipped with a locking element 18 that locks with the side of the guide rails A when it slides to its final position. The rear transfer plate is fixed to the elevator via a slide rail assembly B. The slide rail assembly B includes a pair of guide rails B9 parallel to the slide rail assembly A. A sliding seat with sliding engagement is provided within the guide rails B, and this sliding seat is fixed to the rear transfer plate. The rear transfer plate is fixedly equipped with a locking element that locks with the side of the guide rails B when it slides to its final position. This allows for the sliding adjustment of the front and rear transfer plates relative to guide rails A and B, respectively, thereby facilitating the adjustment of the support positions of the front and rear transfer plates and their relative distance, and improving the stability of the pipe support.

[0022] Furthermore, to facilitate the lateral and longitudinal adjustment of the sliding seat, the aforementioned sliding seat is a roller seat 15. The roller seat has a vertical strip-shaped sliding hole 1501, and the roller integrated bolt 16 inside the roller seat is vertically slidingly engaged with the strip-shaped sliding hole. After sliding into place, it is locked to the bolt by a nut to form a fixed position. The aforementioned locking member 18 is located above the sliding seat. The locking member is a bolt seat with bolt holes, and after connecting the bolt holes with hand-tightened bolts, it abuts against the top side of the corresponding guide rail to form a locking fixation.

[0023] Furthermore, in order to achieve synchronous lifting of all rear transfer plates 7, the aforementioned lifting mechanism includes a motor 10, a transmission chain 11, a synchronous shaft 12, a screw jack 13, and a spiral bevel gear steering box 14. The motor is fixed to the pipe cleaning platform. Screw jacks are evenly distributed below the guide rail B9, and the guide rail B is fixed to the lifting top rod of the screw jack. The casing of the screw jack is fixed to the pipe cleaning platform. The screw jacks located below the same guide rail B form synchronous transmission through the synchronous shaft. The synchronous shaft between a pair of adjacent screw jacks is connected to the spiral bevel gear steering box. The spiral bevel gear transmission boxes below the guide rails on both sides are connected by the synchronous shaft to form synchronous rotation. That is, all screw jacks form synchronous lifting. One of the synchronous shafts integrates a sprocket and is connected to the transmission wheel of the motor output shaft through the transmission chain.

[0024] Furthermore, in order to facilitate the adaptation of the transfer plate assembly to the rotation conditions of the pipe fittings and reduce pipe fitting wear, the aforementioned pre-lift transfer plate 6 is provided with rollers 19 at the trough of the pipe conveying surface to provide rolling support for the pipe fittings at the trough.

[0025] The pipe cleaning platform is used as follows: Pipes are fed from one side of the transfer plate assembly and roll along the first inclined section of the rear transfer plate 7 towards the trough. When the pipe approaches the trough, the rear transfer plate descends, and the pipe is then supported by the inclined surface of the front transfer plate 6 from the crest to the trough. The pipe rolls along the inclined surface of the front transfer plate to the trough, reaching the first pipe processing station. After processing at the first station, the rear transfer plate rises again, and its inclined surface lifts the pipe at the trough of the front transfer plate, causing it to roll again towards the trough. When the pipe approaches the trough, the rear transfer plate descends, and the pipe falls back into the conveying surface of the front transfer plate. This process is repeated until the pipe reaches the second trough, reaching the second pipe processing station. In this manner, pipes are sequentially transferred to each station and finally discharged along the inclined surface at the end of the rear transfer plate. Each time a pipe fitting is transferred to a workstation, the pipe cleaning equipment at the pipe end is activated to clean the inner wall of the pipe. The cleaning fluid flows into the diversion plate 201 of the collection tray 2, and is then diverted to the guide channels 202 on both sides. After being filtered and absorbed by the filter steel mesh and oil-absorbing medium in the guide channels, the cleaning fluid flows to the return channel 501 at the top of the circulating liquid tank 5. After being filtered and absorbed by the filter steel mesh and oil-absorbing medium in the return channel, it flows back into the circulating liquid phase, forming a secondary filtration and oil-absorbing operation, which significantly reduces the filtration pressure of the filtration system in the circulating liquid tank. When the filter steel mesh and oil-absorbing medium reach saturation, they can be manually replaced or cleaned for maintenance, which is convenient and efficient.

[0026] The above description is intended to illustrate the technical means of this utility model and is not intended to limit the technical scope of this utility model. Any obvious improvements or substitutions made to this utility model by those skilled in the art based on existing common knowledge also fall within the protection scope of the claims of this utility model.
