Description

Bubbling tube dredging tool

Technical Field

The utility model relates to a bubbling pipe dredging tool which has a simple and easy-to-use structure and can avoid downtime of a glass molten pool.

Background

Currently, bubblers are commonly used in glass melting furnaces used in glass manufacturing lines to improve the melting efficiency of the glass and enhance the fining and homogenization of the glass melt. The bubbling pipe is used for leading purified compressed gas to enter the glass melt from the bottom of the pool, so that bubbles with certain pressure are generated in the glass melt in the deep layer of the molten pool, and the bubbles rapidly rise to the surface of the glass melt to be broken, absorb small bubbles in the glass melt in the rising process, rapidly grow up, stir the surrounding glass melt and force the glass melt to be homogenized and clarified. Has obvious effects of improving the glass quality and the glass melting rate, saving energy and reducing emission.

The bubbling tube of the tank furnace is long cylindrical and is provided with a vent pipe with a vertical axial through hole. The bubbling pipe is installed below the melting tank furnace, the upper end is inserted into the glass melt, and the lower end is connected with an oxygen pipeline. Oxygen pipeline continuously lets in oxygen to bubble tube through the lower extreme of bubble tube, and oxygen passes through bubble tube and gets into in the glass molten bath, and the bubble is blown out to glass melt in, and the bubble takes away little bubble and makes glass quality higher.

However, as the top of the bubbling pipe is contacted with the glass melt and then has higher temperature, the glass melt at the top of the bubbling pipe has higher fluidity, after the high-pressure gas on the bubbling pipe leaves, the top of the bubbling pipe and the gas pipe form short negative pressure, and the high-fluidity glass melt can enter the bubbling head to flow downwards under the short negative pressure condition and solidify, so that the glass melt solidifies and crystallizes to block the bubbling pipe. The blockage of the bubbler tube may be detected by measuring the pressure of the gas within the bubbler tube, indicating that the bubbler tube is blocked when the pressure increases.

In the case of a bubbler tube blockage, the problem of the duplug can be solved by replacing the bubbler tube, but the replacement can lead to downtime of the glass bath, thereby creating a problem of inefficiency. At present, a bubbling pipe dredging tool is generally used in the industry to extend into the bubbling pipe from the bottom of the bubbling pipe, and solidified glass in the bubbling pipe is removed by knocking a base of the dredging tool.

However, during the break-out process, the bubbler tube break-out tool may protrude excessively outside the bubbler tube to contact the glass melt because the length of the bubbler tube break-out tool into the bubbler tube cannot be controlled. In this case, a large temperature difference between the front end of the bubbler tube dredging tool and the glass melt will cause local solidification of the glass melt, thereby causing damage to the inner wall of the bubbler tube or sticking of glass, and even causing the bubbler tube dredging tool to be unable to be taken out.

According to the present utility model, there is provided a bubbler tube dredging tool that can remove a glass melt solidified in a bubbler tube for a glass molten pool, the bubbler tube dredging tool comprising a base and a dredging portion, an upper surface of the base being abutted against a lower end surface of the bubbler tube, and the dredging portion being movably mounted to the base such that a length of the dredging portion extending out of the base and into the bubbler tube can be adjusted.

In the utility model, the bubbling pipe dredging tool is changed into two adjustable parts from the integral structure in the prior art, namely a dredging part and a base of the bubbling pipe dredging tool. In this way, the structure of the bubbling pipe dredging tool is optimized to control the length of the bubbling pipe dredging tool entering the bubbling pipe, so that the problem that the bubbling pipe dredging tool is contacted with the glass melt is avoided. Meanwhile, the bubbling tube can be suitable for bubbling tubes of different models.

Detailed Description

The bubbling pipe dredging tool according to the present utility model is described in detail below with reference to the accompanying drawings.

As shown in fig. 1, the bubbling tube dredging tool 1 according to the present utility model comprises a base 2 and a dredging portion 3. The base 2 is inverted T-shaped, and includes a horizontal portion 21 and a vertical portion 22, which may be integrally formed. In fig. 1, the horizontal portion 21 and the vertical portion 22 are each cylindrical, but are not limited to the specific embodiment illustrated, and the horizontal portion 21 and the vertical portion 22 may be any other suitable shape. In addition, the base 2 has a mounting hole 20 passing through the center of the vertical portion 22 and through the horizontal portion 21, and this mounting hole 20 has a screw hole portion. Preferably, the mounting hole 20 is a threaded hole portion throughout its length. In alternative embodiments, the mounting holes 20 are not all threaded hole portions, but only a portion of the mounting holes 20, preferably 2/3 or 1/2 of the mounting holes, may be occupied by threaded hole portions.

The pull through 3 is of an elongated cylindrical shape, and is provided at a lower end portion thereof with external threads 30 to be combined with a threaded hole portion of the mounting hole 20 of the base 2 to mount the pull through 3 to the base 2. In addition, the lower end surface of the pull through 3 is provided with a groove 300 (see fig. 3) in a straight shape, and in the case where the pull through 3 is coupled to the base 2, a user may insert a general-purpose rotation tool, such as a screwdriver, into the groove 300, thereby rotating the pull through 3 so that it moves up and down with respect to the base 2.

As shown in the sectional view of fig. 2, when the bubbler tube 100 is dredged, the dredging portion 3 of the bubbler tube dredging tool 1 is inserted into the bubbler tube 100 to remove glass solidified in the bubbler tube 100. In the solution according to the utility model, in order to avoid that the break-through portion 3 protrudes excessively into and out of the bubbler tube 100 and thus comes into contact with the glass melt above the bubbler tube 100, the tip of the break-through portion 3 does not reach the tip of the bubbler tube 100 but is separated by a distance less than the length of engagement of the break-through portion 3 into the base 2 by the external screw thread 30 when the upper surface of the base 22 of the bubbler tool 1 abuts the lower end of the bubbler tube 100. In this case, the pull through 3 is driven by a common rotary tool so that it moves slowly upwards relative to the base 2, in such a way that the pull through 3 is prevented from moving upwards too fast into the glass melt above the bubbler tube 100.

In alternative embodiments according to the present utility model, the shape of the recess 300 is not limited to a "straight" shape, and other suitable shapes of the recess 300 can be envisioned by those skilled in the art. For example, as shown in fig. 4, the recess 300 may be in a cross shape or a prismatic shape.

In addition, according to the technical scheme of the utility model, the bubbling pipe dredging tool can be provided with dredging parts with different lengths according to the type of the bubbling pipe or different blocking positions. In other words, the bubbler tube dredging tool can be adapted to different models of bubbler tubes by simply replacing the dredging portion.

In a preferred embodiment according to the present utility model, the dredging portion 3 of the bubbling tube dredging tool 1 is engraved with a scale (not shown) that takes the top end point of the dredging portion as zero scale. Thus, the specific length dimension of the dredging part extending into the bubbling pipe can be known by reading the scale of the upper surface of the base of the dredging part.
