[0024] In an exemplary embodiment, Figure 1-3 As shown, this embodiment provides a quartz glass plasma melting device, which includes a machine base 1, which is long and has a fixed base 2 at one end and a movable base 3 at the other end that moves back and forth relative to the fixed base 2. A first connecting ring 4 is respectively provided on the opposite side of the fixed base 2 and the movable base 3; the device also includes a melting tube 5, and the two ends of the melting tube 5 are respectively provided with a second connecting ring 6 that can be docked and locked with the two first connecting rings 4. The first connecting ring 4 and the docked second connecting ring 6 can be locked by a bolt 7. Specifically, when installing the melting tube 5, one end of the melting tube 5 is first docked with the fixed base 2, and then the movable base 3 is moved so that the other end is also docked, and finally locked by the bolt 7 (the bolt 7 can be The machine base 1 is also provided with a protective cover 8 that can cover the melting tube 5 locked between the fixed seat 2 and the movable seat 3. The covering of the protective cover 8 is carried out after the docking and locking are completed, so that the melting tube 5 is limited between the movable seat 3, the fixed seat 2, the protective cover 8 and the machine base 1. A nozzle 9 that can spray water onto the melting tube 5 is provided in the protective cover 8. A mounting pipe 10 extending along the length direction of the machine base 1 is also provided in the protective cover 8. The nozzle 9 includes a plurality of nozzles installed in sequence on the mounting pipe 10, and the mounting pipe 10 supplies cooling water thereto through a connecting pipe; the machine base 1 is also provided with a diversion groove 11 for receiving water from the nozzle 9, and the water flows into the diversion groove 11 and is diverted away from the bottom.

[0025] In the above embodiment, the melting barrel 5 can be locked by moving the mobile seat 3 away from and close to the fixed seat 2 in cooperation with the first connecting ring 4 and the second connecting ring 6, and then the operation can be started after covering the protective cover 8. When cooling is required, cooling water is introduced to the nozzle 9 through the connecting pipe. Multiple nozzles 9 can spray cooling water to the melting barrel 5 at a larger flow rate, thereby further improving the cooling efficiency and solving the problem of low cooling efficiency in the prior art.

[0026] like Figure 1-3 As shown, further, the protective cover 8 has a long side extending axially along the melting tube 5, and the end faces of both ends of the protective cover 8 are respectively provided with a semi-ring opening 12 for the second connecting ring 6 to be inserted into, and the semi-ring opening 12 is buckled on the second connecting ring 6, thereby forming a better protection for this place to avoid water splashing out from this place. In more detail, the inner side of the semi-ring opening 12 is also fixedly connected with an arc-shaped baffle 13, and the two arc-shaped baffles 13 can be close to the side of the two second connecting rings 6 that are close to each other, and the arc-shaped baffles 13 are blocked on the inside to play a better protective role.

At the same time, such a setting can also make the water falling on the guide rail 14 flow faster to the inner guide groove 11 to prevent water from overflowing). This can increase the contact surface and ensure smooth sliding. At the same time, the support bar 15 also provides a larger sliding support area for the movable base 3, which helps to provide smooth movement.

[0028] In further detail, the opposite sides of the two support bars 15 extend beyond the two sliding bars 16, and a protective frame 17 is provided on the support bar 15.
