As shown in fig. 1 and 2, the embodiment of the present invention provides a surface drying device, which comprises a housing 10 and a negative pressure air pipe 20 for communicating with a negative pressure device 26;

be equipped with the drying chamber in the casing 10, be equipped with the first opening with the drying chamber intercommunication on the casing 10, negative pressure trachea 20 and drying chamber intercommunication.

By adopting the surface drying device, in the process of drying the surface of the steel pipe 30, the negative pressure air flow is generated in the drying cavity under the action of the negative pressure air pipe 20, and the residual water-based pipe making liquid on the surface of the steel pipe 30 can be taken away by the high-speed flowing negative pressure air flow so as to ensure that the surface of the steel pipe 30 is clean. For the artifical scheme of wiping waterborne tubulation liquid with the rag of traditional adoption, efficiency is higher during this scheme surface drying.

In this embodiment, the housing 10 is further provided with a second opening communicating with the drying chamber, and the first opening and the second opening are disposed opposite to each other.

Specifically, because the first opening and the second opening are arranged oppositely, the steel pipe 30 can penetrate into the drying cavity from any opening for drying, and the steel pipe 30 after drying penetrates out from the other opening, so that the steel pipe 30 can be continuously dried in the drying cavity, and the efficiency is higher when the surface of the steel pipe 30 is dried.

In the present embodiment, the housing 10 has a tubular shape, and the two openings are located at both ends of the housing 10.

Specifically, since the housing 10 is tubular, in the process of drying the surface of the steel pipe, the negative pressure airflow flowing at a high speed rebounds when passing through the inner wall of the housing 10, and the rebounded negative pressure airflow acts on the steel pipe 30 more easily, so as to dry the steel pipe 30, so that the efficiency is high when the surface of the steel pipe 30 is dried.

Preferably, a through hole is formed in a middle region of a side surface of the housing 10, and the negative pressure air pipe 20 is communicated with the drying chamber through the through hole.

Particularly, the middle area of the side of the shell 10 is provided with a through hole, the negative pressure air pipe 20 is communicated with the drying cavity through the through hole, and in the process of drying the surface of the steel pipe, cyclone can be formed in the drying cavity, so that the residual water-based pipe making liquid on the surface of the steel pipe 30 can be thoroughly removed, and the efficiency is higher during the surface drying of the steel pipe 30.

Preferably, the side of the negative pressure air pipe 20 is communicated with a pressure relief valve 23.

Specifically, the surface drying device further includes a three-way pipe 21 and a first inner connecting pipe 22, the negative pressure gas pipe 20 is communicated with the three-way pipe 21, and one opening of the three-way pipe 21 is communicated with a relief valve 23 through the first inner connecting pipe 22. When the air in the drying cavity passes through a small gap, the air flow speed and the air pressure in the drying cavity are both increased sharply, and since the negative pressure air pipe 20 is connected with the negative pressure device 26, the excessive air flow speed and the excessive air pressure can overload the negative pressure device 26, so that the current of the negative pressure device is increased and the temperature of the negative pressure device is increased continuously, and when the current of the negative pressure device is increased and the temperature of the negative pressure device is increased to a certain degree, the negative pressure device can even be burnt out. The side of the negative pressure air pipe 20 is communicated with the pressure release valve 23, when the air flow speed and the pressure in the drying cavity are increased to preset values, the pressure release valve 23 is opened, so that the drying cavity can be communicated with the outside, the air flow speed and the pressure in the drying cavity are reduced, the negative pressure equipment 26 is protected safely, and the service life of the negative pressure equipment 26 is prolonged.

Preferably, a gas-liquid separation device 25 is communicated between the negative pressure gas pipe 20 and the negative pressure device 26.

Specifically, the surface drying device further includes a second inner pipe 24, the other opening of the tee 21 communicates with the second inner pipe 24, and the second inner pipe 24 communicates with the negative pressure device 26 through the gas-liquid separation device 25. In the process of drying the surface of the steel pipe 30, the residual aqueous pipe-making liquid on the surface of the steel pipe 30 is taken away by the negative pressure airflow flowing at a high speed, and because the negative pressure air pipe 20 is communicated with the negative pressure equipment 26, the residual aqueous pipe-making liquid on the surface of the steel pipe 30 enters the negative pressure equipment 26 through the negative pressure air pipe 20 along with the negative pressure airflow, and the residual aqueous pipe-making liquid on the surface of the steel pipe 30 enters the negative pressure equipment 26, which may cause people to get an electric shock and burn out the negative pressure equipment 26. And a gas-liquid separation device 25 is communicated between the negative pressure gas pipe 20 and the negative pressure equipment 26, residual water-based pipe making liquid on the surface of the steel pipe 30 enters the gas-liquid separation device 25 along with the negative pressure gas flow through the negative pressure gas pipe 20 for drying, and the dried negative pressure gas flow enters the negative pressure equipment 26. The gas-liquid separation device 25 prevents people from electric shock and burning out the negative pressure equipment 26.

Referring to fig. 2, the surface drying apparatus further includes an air inlet sheet 12 having a central through hole, the air inlet sheet 12 being fitted to both ends of the case 10.

Specifically, the steel tube 30 passes through a central through hole on the air inlet sheet 12 at one end of the housing 10, enters the drying chamber, and passes through the central through hole on the air inlet sheet 12 at the other end of the housing 10 after being dried in the drying chamber. When the gap between the central through hole of the air intake panel 12 and the steel pipe 30 becomes small, the air flow velocity and air pressure passing through the gap become large, and when the gap between the central through hole of the air intake panel 12 and the steel pipe 30 becomes large, the air flow velocity and air pressure passing through the gap become small. The air flow speed and air pressure can be adjusted by changing the size of the gap between the central through hole on the air inlet sheet 12 and the steel pipe 30.
