Description

TECHNICAL FIELD

[0001] The utility model relates to kiln pool wall sealing technical field, especially relates to a photovoltaic glass kiln pool wall structure. BACKGROUND

[0002] As a key equipment in the glass production process, the performance of photovoltaic glass kiln directly affects the yield and quality of glass, as well as the energy consumption and safety stability during production. In the actual operation of photovoltaic glass kiln, the following key technologies and structures are usually involved:

[0003] 1. Pool wall brick structure: The kiln pool wall is built by stacking pool wall bricks. These pool wall bricks are directly in contact with high-temperature glass liquid and have properties such as high temperature resistance and corrosion resistance.

[0004] 2. Selection of refractory materials: Other parts of the kiln also need to be constructed or lined with refractory materials, such as the kiln roof and flue.

[0005] 3. Combustion system: responsible for providing heat for the kiln, melting glass raw materials and maintaining them within the appropriate temperature range.

[0006] 4. Temperature control system: real-time monitoring of the temperature inside the kiln through temperature sensors installed at different positions.

[0007] Currently, in order to improve the performance and production efficiency of photovoltaic glass kiln, manufacturers have adopted various technical and design improvement measures. Some manufacturers invest a lot of effort in the research and development of pool wall brick materials, using new refractory materials or improving existing material formulations to improve the corrosion resistance and high temperature resistance of pool wall bricks; some manufacturers optimize the combustion system, using high-efficiency burners and advanced fuel control technology to improve the thermal efficiency of the kiln and reduce energy consumption; some manufacturers improve the insulation structure of the kiln to reduce heat loss and further improve energy efficiency.

[0008] However, the existing technology still has some problems in the expansion joint treatment of the kiln pool wall. During the operation of the kiln, the traditional adjustment method gradually reduces the closing effect of the expansion joint between the two adjacent pool wall bricks located in the middle of the pool wall, resulting in ineffective closure of the expansion joint. The problem of poor expansion joint closure is more prominent for ultra-white glass melting kiln due to the characteristics of the glass liquid, which causes more serious erosion of the gap between the pool wall bricks. This not only affects the service life of the kiln, but also may cause safety hazards during production, increase production costs, and reduce production efficiency. To solve this problem, an innovative solution is proposed, which is to design a special pool wall structure and use a segmented adjustment method. The lateral movement of the double-sided inclined pool wall bricks in the adjustment section drives the single-sided inclined pool wall bricks to longitudinally extrude the expansion section pool wall bricks, effectively closing the expansion joint and improving the sealing performance and overall stability of the kiln pool wall.

[0029] Working principle:

[0030] The expansion section is composed of a plurality of pool wall bricks 14 arranged in sequence along the longitudinal direction of the pool wall of the kiln body 1, and a first expansion joint is arranged between adjacent pool wall bricks 14. This design takes into account the space requirement of the pool wall bricks 14 during the process of thermal expansion, and provides a basic condition for the closure of the expansion joint. The number ratio of the single-side inclined pool wall bricks 13 to the double-side inclined pool wall bricks 12 in the adjusting section is two to one. The double-side inclined pool wall bricks 12 are located between two single-side inclined pool wall bricks 13, forming a second expansion joint. The double-side inclined pool wall bricks 12 can move along the vertical pool wall longitudinal direction to close the second expansion joint. The special isosceles trapezoidal cross section (bottom angle 60°-90°) of the double-side inclined pool wall bricks 12 enables the double-side inclined pool wall bricks 12 to generate a specific directional component force when subjected to force. The right-angled trapezoidal cross section (the oblique side is parallel to the oblique side of the double-side inclined pool wall bricks 12) of the single-side inclined pool wall bricks 13 is conducive to receiving the thrust force transmitted by the double-side inclined pool wall bricks 12 and converting it into extrusion force along the longitudinal direction of the pool wall. The longitudinal thrust force is generated by the transverse movement of the double-side inclined pool wall bricks 12 in the adjusting section, which drives the single-side inclined pool wall bricks 13 to extrude the pool wall bricks 14 of the expansion section along the longitudinal direction of the pool wall, thereby achieving the closure of the first expansion joint and the second expansion joint. This technology breaks through the limitation of the traditional longitudinal adjustment of the expansion joint, realizes more effective closure control of the expansion joint, and solves the problem of poor closure effect of the expansion joint between the pool wall bricks in the middle part of the pool wall of the existing melting furnace. By starting the motor 5, the output shaft of the motor 5 will drive the fixed screw rod 8 to rotate. During the rotation of the screw rod 8, the conical block 10 sleeved on the screw rod 8 will move under the action of the thread. During the movement of the conical block 10, the steel plate 6 fixed to the conical block 10 will move together. During the movement of the steel plate 6, a force perpendicular to the longitudinal direction of the pool wall of the kiln body 1 will be applied to the double-side inclined pool wall bricks 12. This force overcomes the friction between the double-side inclined pool wall bricks 12 and the surrounding structure and other possible resistance, so that the double-side inclined pool wall bricks 12 begin to move along the vertical pool wall longitudinal direction towards the single-side inclined pool wall bricks 13. The pool wall reserved observation hole 2 is arranged with half bricks to stagger the expansion joint inside and outside, preventing flame overflow and improving the operation safety of the kiln body 1, while not affecting the observation function. The connection between the kiln top and the pool wall of the kiln body 1 adopts a raised structure filled with zircon ramming powder to fill the joint, effectively preventing alkali vapor accumulation from eroding the brick material and fire jumping, prolonging the service life of the kiln body 1 and improving its operation safety.
