[0030] Embodiment 1

[0031] In order to complete the cleaning and drying of steel pipes in one, and reduce the labor intensity of workers manually wiping the residual cleaning liquid on the surface of steel pipes after cleaning, Figure 1-Figure 3 As an embodiment of the present invention, a stainless steel pipe ultra-clean vacuum cavity cleaning device is proposed, including a floor 1, a conveyor 2, a cleaning cavity 3 and a sealing door 4 installed between the conveyor 2 and the cleaning cavity 3 for closing the entrance of the cleaning cavity 3 are installed on the top of the floor 1, a plurality of safety devices 5 for reinforcing the connection strength between the sealing door 4 and the cleaning cavity 3 are installed on the outside of the cleaning cavity 3, a cleaning and drying component 6 acting on the steel pipe inside the cleaning cavity 3 is installed outside the cleaning cavity 3, and a waste liquid treatment tank group 7 is installed on the top of the floor 1. When in use, the staff only needs to put the steel pipe to be cleaned on the conveyor 2, and finally the staff will take away the steel pipe after cleaning and drying inside the cleaning cavity 3. Other operation steps can be operated by one-key operation using the buttons on the equipment. The specific cleaning process of the steel pipe is as follows:

[0032] The conveyor 2 conveys the steel pipe above it into the cleaning chamber 3, and then the sealing door 4 on the cleaning chamber 3 is closed, and the safety device 5 presses the sealing door 4 to increase the tightness of the connection between the sealing door 4 and the cleaning chamber 3, and then the cleaning and drying component 6 cleans and hot-air dries the steel pipe inside the cleaning chamber 3, and finally takes out the cleaned and dried steel pipe in the cleaning chamber 3. The cleaning and drying process of the steel pipe can be completed automatically, and the staff does not need to wipe the cleaning liquid remaining on the surface of the stainless steel pipe due to cleaning, which reduces the labor intensity of the staff and can prevent the problem of poor on-site environment of the steel pipe cleaning caused by the staff wiping the cleaning liquid on the surface of the steel pipe.

[0033] In order to complete the cleaning and drying process of the steel pipe, refer to Figure 2 The cleaning and drying assembly 6 includes a liquid injection pipe 61 installed on the top of the cleaning cavity 3 and connected thereto. Two vacuum ports 62 are provided on the top of the cleaning cavity 3. The end of the cleaning cavity 3 away from the sealing door 4 is connected to a hot air pipe 63. A waste liquid treatment assembly 64 connected to the waste liquid treatment tank group 7 is installed at the bottom of the cleaning cavity 3. When in use, the steel pipe enters the cleaning cavity 3 and closes the sealing door 4. Then, the cleaning liquid is injected into the cleaning cavity 3 from the liquid injection pipe 61 to clean the steel pipe. After the cleaning is completed, the liquid injection pipe 61 is closed, and then the cleaning liquid in the cleaning cavity 3 is removed from the vacuum port 62. All the air in the cleaning cavity 3 is extracted, and the waste liquid generated by the cleaning inside the cleaning cavity 3 is discharged from the waste liquid treatment component 64 to the waste liquid treatment tank group 7, and the waste liquid is recovered in the waste liquid treatment tank group 7, and then hot air is continuously input into the cleaning cavity 3 from the hot air pipe 63 to vacuum dry the steel pipe inside the cleaning cavity 3. After drying, stop supplying hot air to the hot air pipe 63, and take out the cleaned and dried steel pipe inside the cleaning cavity 3, so that the cleaned steel pipe can be dried directly, and there is no need for the staff to manually wipe the residual cleaning liquid on the steel pipe.

[0034] In order to facilitate the control of the smooth discharge of waste liquid generated after cleaning in the cleaning chamber, refer to Figure 3 The waste liquid treatment component 64 includes a waste liquid pipe 641 installed at the bottom of the cleaning chamber 3 and connected thereto, a plurality of three-way ball valves 642 are installed on the waste liquid pipe 641, one side of the waste liquid pipe 641 is connected to a drain pipe 643, the drain pipe 643 is connected to a flange-type pneumatic ball valve 644 away from the cleaning chamber 3, and one end of the flange-type pneumatic ball valve 644 away from the drain pipe 643 is respectively connected to the waste liquid treatment tank group 7 and the external clean water pipeline. When in use, the three-way ball valve 642 and the flange-type pneumatic ball valve 644 on the waste liquid pipe 641 are opened, and the waste liquid generated after cleaning the steel pipe inside the cleaning chamber 3 is discharged into the waste liquid treatment tank group 7 through the waste liquid pipe 641 and the drain pipe 643, and the waste liquid generated after cleaning is recovered and treated.

[0035] When the oil and impurities generated by cleaning the inside of the cleaning chamber 3 clog the connection between the cleaning chamber 3 and the waste liquid pipe 641, the connection between the drain pipe 643 and the waste liquid treatment tank group 7 is closed through the flange type pneumatic ball valve 644, and then the external clean water or hot water is passed into the flange type pneumatic ball valve 644, and is transported to the inside of the cleaning chamber 3 through the flange type pneumatic ball valve 644, the drain pipe 643 and the waste liquid pipe 641, so as to clear the oil and impurities clogged at the interface between the cleaning chamber 3 and the waste liquid pipe 641. After the oil and impurities in the cleaning cavity 3 are pushed away and unblocked by the clean water or hot water delivered in, the connection between the drain pipe 643 and the waste liquid treatment tank group 7 is opened again through the flange-type pneumatic ball valve 644, so that the waste liquid generated by the cleaning steel pipe inside the cleaning cavity 3 can continue to be discharged from the waste liquid treatment tank group 7, which is convenient for draining the waste liquid generated by the cleaning steel pipe for recycling. At the same time, when the oil and impurities generated by the cleaning steel pipe block the interface between the cleaning cavity 3 and the waste liquid pipe 641, it can be unblocked to prevent the waste liquid pipe 641 from being blocked and unable to discharge the cleaning waste liquid inside the cleaning cavity 3.

[0036] In order to facilitate the control of the cleaning process of the steel pipe and protect the cleaning environment, refer to Figure 1 A support plate 14 is fixedly connected to the outside of the cleaning chamber 3, and two support legs 15 are fixedly connected to the bottom of the support plate 14.

The bottom of the guardrail 18 is fixedly connected to the floor 1, and the top of the floor 1 is fixedly connected to the electric control cabinet 19. The conveyor 2, the cleaning chamber 3, the sealing door 4, the safety device 5, the cleaning and drying component 6 and the waste liquid treatment tank group 7 are all electrically connected to the electric control cabinet 19. When in use, the guardrail 18 protects the cleaning chamber 3 and the waste liquid treatment tank group 7 to prevent staff from entering the steel pipe cleaning site and causing a dirty environment. When controlling the cleaning of the steel pipe, you only need to start the button on the electric control cabinet 19, which simplifies the process of cleaning the steel pipe.
