Detailed Description

As shown in fig. 1-2, a liquid discharge tube protection structure includes a filling head 1 and a liquid discharge tube 4 communicated with and disposed at the bottom of the filling head 1, wherein a connecting tube 2 is further connected to the filling head 1 so as to convey a liquid to be filled to the filling head 1, and a solenoid valve is disposed at the joint of the filling head 1 and the connecting tube 2.

In the actual use process, when opening the solenoid valve, the solution that waits to fill can be carried to filling head 1 department through connecting pipe 2, later fills to the container in through fluid-discharge tube 4.

In order to improve the filling precision, the connecting ring 8 is slidably arranged at the bottom end of the liquid discharge pipe 4, the end face of the bottom end of the connecting ring 8 is fixedly connected with a sealing ring 7 through welding, the cross section of the sealing ring 7 is L-shaped so as to be clamped at the opening of the container for filling, the sealing ring 7 is clamped at the opening of the container during filling, the air pressure inside the sealing ring 7 is gradually increased along with the continuous filling of the solution into the container, an L-shaped pressure relief pipe 16 is fixedly connected to the inner wall of the liquid discharge pipe 4, one end of the pressure relief pipe 16 penetrates through the liquid discharge pipe 4 and is fixedly connected with the pressure relief pipe, the other end of the pressure relief pipe 16 extends to the bottom end of the liquid discharge pipe 4, and when the solution is continuously filled into the container, the gas in the container can be extruded through the pressure relief pipe 16.

As shown in fig. 2-5, the filling of the solution can be stopped when the electromagnetic valve is closed, the filling head 1 is driven by external power equipment to move to the next container to be filled for operation, and due to the lack of a sealing structure at the bottom end of the liquid discharge pipe 4, if the filling head 1 is vibrated during the moving process, the liquid in the liquid discharge pipe 4 will drip out from the bottom end of the liquid discharge pipe 4, which is not favorable for protecting the surrounding environment.

Consequently, this scheme is fixed in the outside of go-between 8 and is equipped with a lantern ring 3, and the lantern ring 3 slides and sets up in the outside of fluid-discharge tube 4, a plurality of first bosss of fixedly connected with on the global outside of lantern ring 3, a plurality of second bosss corresponding with first boss of fixedly connected with on the global outside of fluid-discharge tube 4, fixedly connected with guide bar 5 on the first boss top surface for guide bar 5 runs through the second boss and rather than sliding connection, the outside cover of guide bar 5 is equipped with spring 6, and spring 6 sets up between first boss and second boss.

Further, the inner side of the connecting ring 8 is fixedly connected with a second filter plate 10, the inner side of the sealing ring 7 is rotatably connected with a first filter plate 9, the first filter plate 9 is attached to the second filter plate 10, and the first filter plate 9 and the second filter plate 10 are respectively provided with a first filter hole and a second filter hole.

Furthermore, a slide bar 13 is fixedly connected to the first filter plate 9 along the axis thereof, the slide bar 13 passes through the second filter plate 10 and is rotatably connected therewith, a limiting cylinder 12 is sleeved outside the slide bar 13, a support bar 11 is fixedly connected between the peripheral surface of the outer side of the limiting cylinder 12 and the inner side wall of the liquid discharge pipe 4, a spiral groove is formed in the inner wall of the limiting cylinder 12, and a limiting block 15 matched with the limiting groove 14 is fixedly connected to the outer side surface of the slide bar 13, so that the limiting block 15 extends into the limiting groove 14 and is in sliding fit with the limiting cylinder 12 through the limiting groove 14.

When the liquid drainage pipe 4 is gradually removed from the container, the spring 6 can drive the connecting ring 8 and the connecting ring 13 to slide downwards, when the sealing ring 7 is gradually close to the opening of the container, the sealing ring 7 at the bottom end of the filling head 1 is pressed at the opening at the top of the container, the sealing ring can drive the connecting ring 8 to move upwards so as to drive the lantern ring 3 to move upwards against the action force of the spring 6, in the process, the first filter plate 9 can drive the sliding rod 13 to slide upwards so as to enable the sliding rod 13 to move upwards relative to the limiting cylinder 12, the sliding rod 13 can drive the limiting block 15 at the outer side of the sliding rod 13 to move upwards, at the moment, the limiting block 15 can limit the limiting block 15 through the limiting groove 14, the limiting block 15 can drive the sliding rod 13 to rotate when moving upwards along the path of the spiral groove, the sliding rod 13 can drive the first filter plate 9 to rotate, when the first filter hole on the first filter plate 9 is aligned with the second filter hole on the second filter plate 10, the liquid drainage pipe 4 can be discharged into the container through the liquid drainage pipe 4, and the second filter plate 4, and the liquid drainage pipe 4 can be prevented from being discharged through the second filter plate 4 in a reverse sliding mode that the liquid drainage pipe 4 is prevented from being displaced, and the liquid drainage pipe 4 can be prevented from being discharged through the second filter plate 4, and the filter plate 4.

In conclusion, this device can protect fluid-discharge tube 4 through the go-between 8 and the sealing ring 7 that set up on the one hand, avoids fluid-discharge tube 4 and the transition contact of container and damage fluid-discharge tube 4, simultaneously, also can seal its bottom in the in-process that fluid-discharge tube 4 moved away, avoids solution outflow.
