Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of glass kilns, and in particular relates to a flame blocking device for a glass kiln charging pool. Background Art
[0002] At present, traditional glass furnaces often use flame-blocking water bags to block the flame and high-temperature gas from the glass furnace to prevent the flame and high-temperature gas from directly spraying out from the charging port, thereby protecting the equipment and personnel around the charging port. However, in actual operation, the flame-blocking water bag will leak if it is used for no more than 12 months under the long-term effects of the high temperature, atmosphere and batch materials in the glass furnace, which will affect the glass furnace process and reduce production efficiency, and even cause production to stop and damage the glass furnace structure. Utility Model Content

The flame-blocking brick assembly comprises a plurality of vertically detachable zero-expansion silica bricks, and the plurality of zero-expansion silica bricks are sequentially clamped.
[0006] The beneficial effects of adopting the above technical solution are as follows: zero-expansion silica bricks can be protected from corrosion in high-temperature environments and have a long service life; and the device is not water-cooled. Compared with the traditional flame-blocking water bag, it can increase the temperature of the feed pool, speed up the melting rate of the batch material, shorten the formation time of the glass liquid, and thus improve production efficiency; in addition, several zero-expansion silica bricks can be independently installed and disassembled vertically to facilitate subsequent maintenance and replacement without affecting the working conditions of the glass kiln, and have high adjustability.

DETAILED DESCRIPTION
[0034] The utility model will be further described below in conjunction with the accompanying drawings.
[0035] Due to the long-term effects of high temperature, alkaline steam and alkaline powder in the glass kiln, the flame barrier water bag will leak within 12 months of use; if the flame barrier water bag leaks, high-temperature water vapor will be formed, causing the pressure in the glass kiln to increase, affecting the glass kiln process; if the flame barrier water bag leaks, water will come into contact with the high-temperature glass liquid, triggering a violent water vapor explosion, causing damage to surrounding equipment and operators; if the flame barrier water bag leaks, it will cause the batch materials at that location to agglomerate and stratify, resulting in bubbles and stone defects in the glass, thereby reducing the quality of the glass; if the flame barrier water bag leaks, it will cause the temperature of the batch materials at that location to drop, reduce the melting rate of the batch materials, increase the formation time of the glass liquid, thereby reducing production efficiency, and increase the residence time of the glass liquid in the kiln, which increases gas energy consumption; in addition, when replacing a leaking flame barrier water bag, since the equipment structure of the feeding pool 1 is complex and is affected by the high-temperature flame in the glass kiln, it takes a long time to complete the replacement, which will affect production and take a long time to recover.
[0036] Based on this, the utility model provides a flame blocking device for a glass kiln charging pool, such as Figure 1 and Figure 2 As shown, it includes a flame-blocking brick assembly for blocking the feeding port 3, and the flame-blocking brick assembly includes a plurality of zero-expansion silica bricks 2 that can be installed and removed vertically, and the plurality of zero-expansion silica bricks 2 are snap-connected in sequence.
[0037] It can be understood that the zero-expansion silica bricks 2 can remain uncorroded in a high-temperature environment and have a long service life. The device is not water-cooled. Compared with the traditional flame-blocking water bag, it can increase the temperature of the feed pool 1, speed up the melting rate of the batch material, shorten the formation time of the glass liquid, and thus improve production efficiency. In addition, several zero-expansion silica bricks 2 can be independently installed and disassembled vertically to facilitate subsequent maintenance and replacement without affecting the working conditions of the glass kiln, and have high adjustability.
[0038] It should be noted that increasing the temperature of the feed pool 1 can make the batch material melt more evenly, reduce bubbles and stone defects in the glass, thereby improving the quality of the molten glass, and reduce the residence time of the molten glass in the glass furnace, thereby reducing gas energy consumption; in addition, it reduces the volatilization of the batch material, which is beneficial to reducing environmental pollution.
[0039] It should also be noted that the content of silicon dioxide in zero-glass silica bricks is not less than 98%, its refractoriness is 1600°C, and it will not pollute the glass liquid. In addition, its high-temperature expansion coefficient is low, it will not expand or crack after long-term use, and it has good thermal shock resistance and erosion resistance.

The plurality of lifting components 6 are respectively located directly above the plurality of zero-expansion silica bricks 2.
[0043] It can be understood that each clamping member 7 can clamp a zero-expansion silica brick 2 individually, and each lifting member 6 can lift a zero-expansion silica brick 2 individually together with the clamping member 7, which is conducive to vertical installation and replacement of the zero-expansion silica brick 2 after clamping the zero-expansion silica brick 2.
[0044] In one embodiment, the lifting member 6 is a hand chain hoist.
[0045] In one embodiment, load-bearing hooks are welded at equal intervals at the lower end of the load-bearing connecting beam 5, and the lifting component 6 is connected to the load-bearing hooks. The center distance of the load-bearing hooks matches the width of the zero-expansion silica bricks 2, and the arrangement direction of the load-bearing hooks matches the arrangement direction of the zero-expansion silica bricks 2.
[0046] It can be understood that the lifting member 6 is connected to the load-bearing connecting beam 5 by means of a load-bearing hook; the center distance of the load-bearing hook matches the width of the zero-expansion silica brick 2, and the arrangement direction of the load-bearing hook matches the arrangement direction of the zero-expansion silica brick 2, so as to facilitate that several lifting members 6 are respectively located directly above several zero-expansion silica bricks 2.
[0047] In one embodiment, Figure 2 and Figure 4 As shown, the clamping member 7 includes a hook 702 for connecting to the lower end of the lifting member 6, a first connecting rod 703 and a second connecting rod 704 are hinged at the same place of the hook 702, a third connecting rod 705 parallel to the second connecting rod 704 and a fourth connecting rod 706 parallel to the first connecting rod 703 are hinged at the lower ends of the first connecting rod 703 and the second connecting rod 704, respectively, the middle part of the third connecting rod 705 is hinged to the middle part of the fourth connecting rod 706, the lower ends of the third connecting rod 705 and the fourth connecting rod 706 are fixedly connected with a brick clamp 701 for clamping the zero-expansion silicon brick 2, and the clamping end of the brick clamp 701 is horizontal; a second protrusion 203 is provided at the upper end of the zero-expansion silicon brick 2, and second grooves 20301 are provided on both sides of the second protrusion 203, and a clamping block 70101 for clamping into the second groove 20301 is horizontally provided at the clamping end of the brick clamp 701.

[0053] In one embodiment, Figure 1 As shown, the end surface of the zero-expansion silica brick 2 close to the feeding port 3 is closely attached to the hanging wall shell surface 4 on the feeding pool 1.
[0054] It can be understood that the end surface of the zero-expansion silica brick 2 close to the feeding port 3 is in close contact with the L-shaped hanging wall shell surface 4 on the feeding pool 1 to ensure the flame blocking effect.
[0055] It should be noted that the L-shaped hanging wall shell surface 4 generally has an installation error of 1 mm, so the end face of the zero-expansion silica brick 2 close to the feeding port 3 is preferably 1 mm positive and negative difference to ensure that the zero-expansion silica brick 2 fits tightly against the L-shaped hanging wall shell surface 4.
