DETAILED DESCRIPTION

[0023] The application will be further described in detail below with reference to the accompanying drawings.

[0024] The embodiment of the application discloses a high-efficiency cleaning device for stainless steel pipe machining.

[0025] Referring to Figure 1 , Figure 2 , the high-efficiency cleaning device for stainless steel pipe machining comprises a cleaning support 1, a cleaning tank 2 is rotationally arranged on the cleaning support 1, the cleaning tank 2 is horizontally placed, and the rotating shaft direction of the cleaning tank 2 is perpendicular to the length direction of the cleaning tank 2. A cleaning cavity 3 for placing a steel pipe is formed in the cleaning tank 2, and a sealing cover 4 for sealing and covering the opening of the cleaning cavity 3 is rotationally arranged on the outer side wall of the cleaning tank 2; when the sealing cover 4 covers the opening of the cleaning cavity 3, the cleaning cavity 3 forms a closed space at this time. Therefore, the outward diffusion of the organic solvent in the cleaning cavity 3 can be effectively prevented, the harm of the organic solvent to the operator is reduced, and the work safety of the operator is improved.

[0026] As shown in Figure 1 , Figure 2 , the top of the cleaning tank 2 is provided with a liquid inlet pipe 20, the liquid outlet of the liquid inlet pipe 20 is communicated with the cleaning cavity 3, the liquid inlet of the liquid inlet pipe 20 is used for being connected with a pipeline conveying the organic solution, and the on-off of the liquid inlet pipe 20 can be controlled by controlling the valve on the pipeline. The bottom of the cleaning tank 2 is provided with a liquid outlet pipe 5, one end of the liquid outlet pipe 5 is communicated with the cleaning cavity 3, and the other end of the liquid outlet pipe 5 is used for being communicated with a waste liquid collecting tank. The liquid outlet pipe 5 is also provided with a valve for controlling the on-off of the liquid outlet pipe 5.

[0027] After the steel pipe to be cleaned is placed into the cleaning chamber 3, the sealing cover 4 is closed. Then, the inlet pipe 20 is opened and the drain pipe 5 is closed, allowing the organic solution to be continuously injected into the cleaning chamber 3 until the steel pipe is submerged. This achieves immersion cleaning of the steel pipe surface while effectively inhibiting the evaporation and diffusion of organic solvents into the surrounding environment, reducing the hazards posed by organic solvents to operators. After the cleaning work is completed, the drain pipe 5 is opened to drain the organic solvent in the cleaning chamber 3. Once the residual organic solvent on the surface of the steel pipe has evaporated completely, the sealing cover 4 can be opened, and the steel pipe can be removed from the cleaning chamber 3.

[0028] like Figure 1 , Figure 2 As shown, the cleaning support 1 is also equipped with a swing cylinder 6 located at the bottom of the cleaning tank 2. The bottom of the swing cylinder 6 is rotatably mounted on the cleaning support 1, and the piston rod of the swing cylinder 6 is rotatably mounted on the bottom outer wall of the cleaning tank 2. During the cleaning process, the swing cylinder 6 drives the cleaning tank 2 to swing back and forth on the cleaning support 1, so that the organic solvent can more fully contact and react with the contaminants on the surface of the steel pipe, further improving the cleaning effect on the steel pipe.

[0029] like Figure 3 , Figure 4 As shown, the system also includes a feeding rack 7 located outside the cleaning tank 2. A transfer seat 8 is slidably mounted on the feeding rack 7, and the transfer seat 8 is used to move the steel pipe into or out of the cleaning chamber 3. The transfer seat 8 includes a plurality of side panels 82 arranged at intervals along the length of the feeding rack 7, and a plurality of connecting rods 83 sequentially inserted and fixed to each side panel 82. The length of the connecting rods 83 extends along the length of the feeding rack 7, and the side panels 82 are sequentially connected and fixed by the connecting rods 83. The side panels 82 are used for placing the steel pipe on the transfer seat 8.

[0030] like Figure 3 , Figure 4 As shown, pulleys 81 are symmetrically arranged on the left and right sides of the enclosure 82. The material transfer seat 8 is slidably mounted on the feeding frame 7 along its length via the pulleys 81. A chain 70 is mounted on the feeding frame 7, and the chain 70 is rotatably mounted on the feeding frame 7 via gears. The feeding frame 7 is also equipped with a drive source 73 for driving the gears to rotate. In this embodiment, the drive source 73 is an electric motor. The drive source 73 drives the gears to rotate, and as the gears rotate, they drive the chain 70 to rotate synchronously.

[0031] like Figure 3 , Figure 4As shown, a push-pull member 71 is rotatably mounted on the chain 70. A clamping groove 72 is formed at the end of the push-pull member 71 facing the transfer seat 8. The push-pull member 71 is clamped and limited on the enclosure plate 82 by the clamping groove 72. When the chain 70 rotates under the drive of the drive source 73, the chain 70 can drive the transfer seat 8 into or out of the cleaning chamber 3 via the push-pull member 71. A track 30 is fixedly mounted on the inner wall of the cleaning chamber 3. The length direction of the track 30 extends along the direction in which the transfer seat 8 moves into the cleaning chamber 3. The tracks 30 are symmetrically arranged on the left and right sides of the cleaning chamber 3, and each track 30 is located on the sliding path of its respective opposite pulley 81.

[0032] like Figure 3 , Figure 4 As shown, the feeding rack 7 is also fixedly installed with multiple crossbeams 74 arranged at intervals along the length of the chain 70. The crossbeams 74 are located below the transfer seat 8, and the chain 70 is sequentially movably threaded through each crossbeam 74. The crossbeams 74 not only enhance the structural strength of the feeding rack 7, but also guide and limit the chain 70, ensuring stable operation of the chain 70.

[0033] When the transfer seat 8 moves from the feeder 7 into the cleaning chamber 3, the pulleys 81, supported by their respective tracks 30, will drive the transfer seat 8 to gradually move into the cleaning chamber 3. Once the transfer seat 8 has successfully moved into the cleaning chamber 3, the push-pull member 71 will rotate around its own axis from the enclosure 82, thus releasing the limit of the push-pull member 71 on the transfer seat 8 and completely separating the transfer seat 8 from the feeder 7.

[0034] like Figure 2 , Figure 3 As shown, positioning elements 80 are symmetrically fixedly installed on the front and rear sides of the transfer seat 8, and the length of the positioning elements 80 extends along the sliding direction of the transfer seat 8. After the transfer seat 8 is completely moved into the cleaning chamber 3, the opening of the cleaning chamber 3 is sealed by the sealing cover 4. At this time, the positioning element 80 facing the sealing cover 4 will abut against the inner wall of the sealing cover 4, while the positioning element 80 away from the sealing cover 4 will abut against the opposite inner wall of the cleaning chamber 3. With the positioning of the front and rear positioning elements 80, the stability of the transfer seat 8 in the cleaning chamber 3 can be ensured, preventing the transfer seat 8 from shifting during cleaning, ensuring the stability and reliability of the steel pipe on the transfer seat 8, and the steel pipe placed on the transfer seat 8 is tied and fixed to the transfer seat 8.

[0035] When it is necessary to remove the transfer seat 8 from the cleaning chamber 3, simply reconnect the push-pull component 71 to the transfer seat 8, and then rotate the chain 70 in the reverse direction. Under the combined action of the chain 70 and the push-pull component 71, the transfer seat 8 can be smoothly removed from the cleaning chamber 3, making the operation convenient and quick.

[0036] The operating principle is as follows: After the steel pipe to be cleaned is placed into the cleaning chamber 3, the sealing cover 4 is closed. Then, the inlet pipe 20 is opened and the drain pipe 5 is closed, allowing the organic solution to be continuously injected into the cleaning chamber 3 until the steel pipe is submerged. This achieves immersion cleaning of the steel pipe surface while effectively inhibiting the evaporation and diffusion of organic solvents into the surrounding environment, reducing the hazards posed by organic solvents to operators. After the cleaning work is completed, the drain pipe 5 is opened to drain the organic solvent in the cleaning chamber 3. Once the residual organic solvent on the steel pipe surface has evaporated completely, the sealing cover 4 can be opened, and the steel pipe can be removed from the cleaning chamber 3.

[0037] During the cleaning process, the cleaning tank 2 is driven to swing back and forth on the cleaning support 1 by the swing cylinder 6, so that the organic solvent can come into more complete contact with the contaminants on the surface of the steel pipe and react more effectively, thus improving the cleaning effect on the steel pipe.

[0038] When the transfer seat 8 moves from the feeding rack 7 into the cleaning chamber 3, the pulleys 81, supported by their respective tracks 30, will drive the transfer seat 8 to gradually move into the cleaning chamber 3. Once the transfer seat 8 has successfully moved into the cleaning chamber 3, the push-pull component 71 rotates around its own axis from the enclosure 82. At this point, the push-pull component 71 can be released from its limiting position on the transfer seat 8, allowing the transfer seat 8 to completely separate from the feeding rack 7. When it is necessary to remove the transfer seat 8 from the cleaning chamber 3, simply reconnect the push-pull component 71 to the transfer seat 8, and then rotate the chain 70 in the reverse direction. Under the combined action of the chain 70 and the push-pull component 71, the transfer seat 8 can be smoothly removed from the cleaning chamber 3, making the operation convenient and quick.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
