Description

Technical Field

[0001] The present application relates to the technical field of oxygen pipeline cleaning, and in particular to a degreasing and cleaning mechanism for the inner wall of an oxygen pipeline. Background Art

[0002] The debris formed during the manufacturing and installation of oxygen pipelines include welding slag, rust, grease, dirt, etc. Their presence poses a safety hazard to production and will bring many disadvantages to the production process. In the pure oxygen environment of the oxygen system industrial pipeline, iron, copper and other metal materials are in the combustion-supporting condition of pure oxygen. As long as the impurities in the pipe collide with the fluid during the rapid operation and produce a spark, it can cause the rapid combustion of iron and copper metal materials. The rapid accumulation of heat can cause the pipeline system to explode, resulting in serious safety accidents; or cause the measuring instruments, meters and other accessories on the equipment and pipelines to lose their precision or be damaged; block the process flow; affect the quality and output of the product, etc. Therefore, before installing the oxygen pipeline, the oxygen pipeline needs to be degreased and cleaned.

[0003] In the related art, the degreaser is supplied to the nozzle through a hose. After flowing through the first medium channel and the second medium channel, the degreaser is sprayed out from a plurality of spray holes to spray onto the inner wall of the industrial oxygen pipeline to achieve the purpose of spray cleaning. At the same time, the cleaning personnel can achieve the overall cleaning of the inner wall of the industrial oxygen pipeline by pushing the nozzle. By setting the pulley, damage to the inner wall of the pipeline can be avoided, and the reaction force generated by the spraying degreaser can be suppressed by the supporting force of the pulley, which is convenient for the cleaning personnel to control the spraying direction of the degreaser.

[0004] The entire inner wall of the oxygen pipeline is cleaned by pushing the nozzle. However, because the spray holes are located on the outer wall of the nozzle, the degreaser can only be discharged outward in the direction of the spray holes. The limited number of spray holes means that the degreaser has a limited spray range, which prevents it from flushing all locations on the inner wall of the oxygen pipeline. This results in blind spots during cleaning, hindering the thorough cleaning of the oxygen pipeline and reducing the cleaning effect. Therefore, those skilled in the art have provided a degreasing and cleaning mechanism for the inner wall of an oxygen pipeline to address the problems raised in the above-mentioned background art.

DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-4 This application is described in further detail.

[0033] The embodiment of the present application discloses a degreasing and cleaning mechanism for the inner wall of an oxygen pipeline. Figure 1-4 A degreasing and cleaning mechanism for the inner wall of an oxygen pipeline comprises a workbench 1, a support plate 2 being fixed to one side of the top of the workbench 1, a sleeve 3 being rotatably connected to one side of the support plate 2, a nozzle 4 being inserted and connected in the sleeve 3, a support plate 5 being fixed to one end of the nozzle 4, and a spray hole 6 being opened on the outer wall of the nozzle 4 near the support plate 5;

[0034] A rotating assembly 7 is fixedly disposed on one side of the support plate 2 and connected to the sleeve 3 to drive the sleeve 3 to rotate;

[0035] A rolling assembly 8, which is provided on the outer wall of the support plate 5 and is used to support the movement of the nozzle 4;

[0036] The limiting assembly 9 is provided between the sleeve 3 and the nozzle 4 and is used to support the insertion movement of the nozzle 4.

[0037] In this embodiment, the oxygen pipeline is first placed on the first support frame 10 and the second support frame 12. At this time, the oxygen pipeline is in a horizontal state. Then, the nozzle 4 is pushed to move the nozzle 4 in the oxygen pipeline. The degreasing agent is then transported into the nozzle 4 by an external water pump, and the setting of the support plate 5 makes the other end of the nozzle 4 in a closed state, so that the degreasing agent can be discharged through the injection hole 6, and the inner wall of the oxygen pipeline can be flushed. At the same time, under the movement of the rotating component 7, the sleeve 3 is driven to rotate. With the cooperation of the limiting component 9, the sleeve 3 can drive the synchronous rotation of the nozzle 4. The injection direction of the injection hole 6 changes continuously during the rotation of the nozzle 4, thereby cleaning various positions of the inner wall of the oxygen pipeline, avoiding the existence of cleaning dead corners, facilitating the full cleaning of the oxygen pipeline, and improving the cleaning effect of the oxygen pipeline.

[0038] In a further embodiment, Figure 2 As shown, the rotating assembly 7 includes a driving motor 71 fixedly arranged on one side of the support plate 2, a driving wheel 72 is fixed to the output shaft of the driving motor 71, and a driven wheel 73 meshing with the driving wheel 72 is sleeved on the outer wall of the sleeve 3.

[0039] In this embodiment, when the nozzle 4 sprays the degreasing agent outward through the spray hole 6 to clean the inner wall of the oxygen pipeline, the driving motor 71 drives the rotation of the driving wheel 72, the driving wheel 72 drives the rotation of the driven wheel 73, the driven wheel 73 drives the rotation of the sleeve 3, and the sleeve 3 drives the rotation of the nozzle 4, thereby driving the direction of the spray hole 6 to change continuously, making it convenient to clean various positions on the inner wall of the oxygen pipeline.

[0040] In a further embodiment, Figure 2 As shown, the rolling assembly 8 includes an annular groove 81 formed on the outer wall of the support plate 5 , and a plurality of balls 82 are rollingly connected in the annular groove 81 .

[0041] In this embodiment, when the nozzle 4 moves on the inner wall of the oxygen pipe, the support plate 5 and the ball 82 are used in conjunction to facilitate the support of the nozzle 4, reduce the collision and friction between the nozzle 4 and the inner wall of the oxygen pipe, and avoid damage to the inner wall of the oxygen pipe.

[0042] In a further embodiment, Figure 2 As shown, the limiting assembly 9 includes a limiting plate 91 fixedly arranged on the outer wall of the nozzle 4, and the inner wall of the sleeve 3 is provided with a limiting groove 92 for the limiting plate 91 to slide.

[0043] In this embodiment, when the nozzle 4 is pushed, the cooperation of the limiting plate 91 and the limiting groove 92 facilitates the support of the nozzle 4 and maintains the stable movement of the nozzle 4. At the same time, when the sleeve 3 rotates, the limiting cooperation of the limiting plate 91 and the limiting groove 92 facilitates the synchronous rotation of the sleeve 3 and the nozzle 4.

[0044] In a further embodiment, Figure 1 As shown, a first support frame 10 is fixed in the middle of the top of the workbench 1, a limiting ring 11 is fixed to the top of the first support frame 10, and a second support frame 12 is provided on one side of the top of the workbench 1 so as to be liftable. The second support frame 12 is connected to the workbench 1 through a lifting plate 13, and a lifting component 14 is provided at the top of the workbench 1 to drive the second support frame 12 to move.

[0045] In this embodiment, when the oxygen pipeline is placed on the first support frame 10 and the second support frame 12 for cleaning, the top of the first support frame 10 and the top of the second support frame 12 are in a parallel state, that is, the oxygen pipeline is in a parallel state, and the inner wall of the oxygen pipeline can be cleaned. When the cleaning is completed, the nozzle 4 is removed from the oxygen pipeline, and then the second support frame 12 is driven to move upward under the movement of the lifting assembly 14, so that one end of the oxygen pipeline can be lifted, so that the oxygen pipeline is in an inclined state, and when the oxygen pipeline is lifted, the lower end of the oxygen pipeline abuts against the limit ring 11. With the cooperation of the limit ring 11, it is convenient to support the oxygen pipeline and prevent the oxygen pipeline from sliding. The width of the limit ring 11 is smaller than the thickness of the side wall of the oxygen pipeline, so that the limit ring 11 will not block the oxygen pipeline. When the oxygen pipeline is lifted and tilted, the degreasing agent remaining in the oxygen pipeline can be quickly discharged, which facilitates the cleaning of the oxygen pipeline and improves the cleaning efficiency of the oxygen pipeline.

[0046] In a further embodiment, Figure 3 As shown, the lifting plate 13 includes a vertical plate 131 fixedly arranged at the bottom end of the second support frame 12 and interlaced with the workbench 1. A bottom plate 132 is fixed to the bottom end of the vertical plate 131, and abutment blocks 133 are fixed on both sides of the top of the bottom plate 132.

[0047] In this embodiment, the interlacing movement of the vertical plate 131 facilitates the up and down movement of the second support frame 12 on the workbench 1, and the bottom plate 132 and the resistance block 133 are located below the workbench 1. In this way, when the second support frame 12 moves up and down, the bottom plate 132 and the resistance block 133 limit the second support frame 12 to prevent the second support frame 12 from detaching.

[0048] In a further embodiment, Figure 4 As shown, the lifting assembly 14 includes a push rod 141 hingedly arranged on one side of the second support frame 12, and the bottom end of the push rod 141 is hinged with a slider 142. The top of the workbench 1 is provided with a slide groove 143 for the slider 142 to slide, and the slide groove 143 is fixedly connected to the slider 142 through an electric telescopic rod 144.

[0049] In this embodiment, when the oxygen pipeline needs to be raised, the movement of the electric telescopic rod 144 drives the movement of the slider 142, and the slider 142 drives the push rod 141 to move, and the push rod 141 drives the second support frame 12 to move upward, and the second support frame 12 drives one end of the oxygen pipeline to move upward, so that the oxygen pipeline is in a tilted state, thereby facilitating the discharge of the degreasing agent remaining in the oxygen pipeline, facilitating the cleaning of the oxygen pipeline, and improving the cleaning efficiency of the oxygen pipeline.

[0050] The implementation principle of the degreasing and cleaning mechanism for the inner wall of an oxygen pipeline in the embodiment of the present application is as follows: first, the oxygen pipeline is placed on the first support frame 10 and the second support frame 12. At this time, the oxygen pipeline is in a parallel state. Then, the nozzle 4 is pushed to move the nozzle 4 in the oxygen pipeline. Then, the degreasing agent is delivered to the nozzle 4 through an external water pump. In this way, the degreasing agent can be discharged through the injection hole 6 to flush the inner wall of the oxygen pipeline. At the same time, under the movement of the driving motor 71, the driving wheel 72 is driven to rotate. The driving wheel 72 drives the rotation of the driven wheel 73. The driven wheel 73 drives the rotation of the sleeve 3. The sleeve 3 drives the rotation of the nozzle 4, thereby driving the injection hole 6. The direction of rotation is constantly changing, which makes it convenient to clean various positions of the inner wall of the oxygen pipeline, avoids the existence of cleaning dead corners, facilitates the full cleaning of the oxygen pipeline, and improves the cleaning effect of the oxygen pipeline. When the cleaning is completed, the nozzle 4 is removed from the oxygen pipeline, and then the movement of the electric telescopic rod 144 drives the movement of the slider 142, and the slider 142 drives the push rod 141 to move, and the push rod 141 drives the second support frame 12 to move upward, and the second support frame 12 drives one end of the oxygen pipeline to move upward, so that the oxygen pipeline is in an inclined state, thereby facilitating the discharge of the degreasing agent remaining in the oxygen pipeline, facilitating the cleaning of the oxygen pipeline, and improving the cleaning efficiency of the oxygen pipeline.

[0051] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
