Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of metallurgical furnace production equipment, and specifically relates to a suspended ceramic tube fire-blocking beam. Background Art
[0002] Metallurgical furnaces usually use water beams, air beams or insulation cotton beams to achieve the physical partition walls of certain heating sections in the kiln and the requirements of stable temperature and atmosphere in the temperature control zone.
[0003] For continuous metallurgical furnaces, such as walking beam furnaces, ring furnaces, roller-bottom furnaces, etc., the reasonable setting of fire-blocking beams is of great auxiliary effect in adjusting the uniformity of furnace temperature and reducing the temperature difference between the upper and lower sections of the furnace. However, traditional water beams and air beams generally use refractory insulation materials with a large specific gravity. Generally, water or air convection is required to ensure their service life. Water pumps, fans and corresponding pipelines are required. The construction operation is complicated and not conducive to energy saving and consumption reduction. Insulation cotton beams can avoid such problems, but the installation and disassembly are relatively complicated. If there is oxidation damage, the fire-blocking beam will lose its function, and there is a safety hazard of fire in the furnace. Summary of the invention
[0004] The purpose of the utility model is to provide a suspended ceramic tube fire-blocking beam with reasonable structure, simple assembly and disassembly, convenient adjustment, durability and low cost in view of the above-mentioned deficiencies and defects in the prior art.
[0005] The technical solution adopted by the utility model is: it includes a kiln steel structure, a kiln wall, a kiln top and a ceramic tube fire-blocking beam arranged between each temperature section of the kiln body, etc. The ceramic tube fire-blocking beam is composed of a ceramic tube, a hanging steel rod, a steel structure ring beam, thermal insulation cotton, etc. The steel structure ring beam is fixedly installed on the kiln steel structure where the fire-blocking beam needs to be installed on the kiln top. A round hole is arranged at the upper end of the ceramic tube. The hanging steel rod passes through the round hole arranged on the ceramic tube and is fixed on the steel structure ring beam. The ceramic tube passing through the kiln top is hoisted to a set height. After the ceramic tube is hoisted through the kiln top section at the upper part of the ceramic tube, thermal insulation cotton I is filled between the ceramic tube and the kiln top to strictly seal the gap between the two. The fire-blocking beam and the furnace top form a closed whole, which reduces the temperature difference between the upper and lower sections in the furnace and isolates the temperature and atmosphere inside and outside the kiln body. The ceramic tubes hoisted tightly in the width direction form a closed fire-blocking beam on the upper part of the furnace.
[0006] Furthermore, 2 to 5 circular holes are arranged at a certain distance on the upper end of each ceramic tube, so that when installing and hanging the ceramic tube, the height requirement of the fire-blocking beam can be used to determine which row of circular holes the hanging steel rod passes through.
[0007] Furthermore, the thermal insulation cotton is 1400°C zirconium-containing fiber cotton, the hanging steel rod is made of Q235 steel rod, and a gasket is sleeved on the hanging steel rod.
[0008] The beneficial effect of the utility model is that since the upper part of the ceramic tube is hoisted on the top of the furnace body, loose cotton of corresponding material is used for filling after the hoisting is completed, which effectively reduces the heat dissipation. The ceramic tube cooperates with the hoisting in the width direction of the kiln to assist each other, and the structure is reasonable and light, and easy to load and unload. It effectively solves the problem that the traditional water beam or air beam needs to increase the circulating air or circulating water. At the same time, it is more convenient to load and unload than the traditional insulation cotton beam, durable, easy to load and unload, and low cost.
[0009] The following structural drawings further illustrate the utility model. BRIEF DESCRIPTION OF THE DRAWINGS
[0010] Figure 1 This is a schematic diagram of the overall cross-sectional structure of the utility model;
[0011] Figure 2 It is a schematic diagram of the overall side structure of the utility model.
[0012] In the figure: 1 is the kiln wall, 2 is the ceramic tube, 3 is the round hole, 4 is the hanging steel rod, 5 is the steel structure ring beam, 6 is the kiln roof, 7 is the insulation cotton I, and 8 is the insulation cotton II. DETAILED DESCRIPTION
[0013] As shown in Figures 1 and 2, the suspended ceramic tube fire-blocking beam includes components such as the kiln body steel structure, the kiln wall 1, the kiln roof 6 and the ceramic tube fire-blocking beams arranged between the temperature sections of the kiln body. The ceramic tube fire-blocking beam is composed of a ceramic tube 2, a hanging steel rod 4, a steel structure ring beam 5 and thermal insulation cotton. The steel structure ring beam 5 is fixedly installed on the kiln body steel structure where the fire-blocking beam needs to be installed between the temperature sections of the kiln roof 6. A circular hole 3 is arranged at the upper end of the ceramic tube 2, and the hanging steel rod 4 passes through the circular hole 3 arranged on the ceramic tube 2 and is fixed on the steel structure ring beam 5. The hanging steel rod 4 is made of Q235 steel rod, and a gasket is sleeved on the hanging steel rod 4. Since 5 circular holes 3 are arranged at a certain distance at the upper end of each ceramic tube, when installing and hanging, the hanging steel rod 4 can be determined according to the height requirements of the fire-blocking beam to pass through the row of circular holes, and the ceramic tube 2 passing through the kiln roof 6 can be hoisted to the set height. In order to effectively reduce heat dissipation and make it have stable fire-resistant and heat-insulating properties and thermal shock resistance, after the ceramic tube is hoisted, insulation cotton I7 is filled in the upper part of the ceramic tube 2 through the kiln top section, and insulation cotton II8 is filled between the ceramic tube and the kiln top to strictly seal the gap between the two. The fire-blocking beam and the furnace top form a closed whole, which reduces the temperature difference between the upper and lower sections in the furnace and isolates the temperature and atmosphere inside and outside the kiln body. The insulation cotton can be selected from 1400℃ zirconium-containing fiber cotton. The ceramic tubes 2 that are tightly arranged and hoisted in the width direction form a closed fire-blocking beam at the top of the furnace. Insulation cotton is filled between the ceramic tube 2 and the kiln top 6 to strictly seal the gap between the two. The fire-blocking beam and the furnace top form a closed whole, which reduces the temperature difference between the upper and lower sections in the furnace and isolates the temperature and atmosphere inside and outside the kiln body.
[0014] When the utility model is implemented, the fire blocking beam can be adjusted to a suitable height in time according to the process requirements of firing different products, and the ceramic tube can be replaced in time when it is damaged. It has the advantages of reasonable structure, simple loading and unloading, convenient adjustment, durability, etc., and can be widely used in various continuous production metallurgical furnaces.
[0015] The above description is only a detailed description of a specific embodiment of the utility model, but the structural features of the utility model are not limited thereto. Any changes or modifications made by any technician in the field of the utility model are covered by the scope of the utility model patent.
