Description

Technical Field

[0001] The invention belongs to the technical field of furnace maintenance, and in particular relates to a filler and production equipment. Background Art

[0002] The blast furnace is made of steel plates as the shell, and the shell is lined with refractory bricks. The blast furnace body is divided into five parts from top to bottom: throat, body, waist, belly, and hearth. Due to the advantages of good technical and economic indicators of blast furnace smelting, simple process, large production volume, high labor production efficiency, and low energy consumption, this smelting method occupies the vast majority of the world's smelting field.

[0003] When high-temperature furnaces are in use, due to the high temperature, high-temperature resistant fillers will be applied on the surface of the lining refractory bricks to ensure the durability and fire resistance of the high-temperature furnaces. However, during the operation of high-temperature furnaces, the insulation materials undergo multiple high-temperature sintering, which will cause linear shrinkage, a shrinkage rate of -3‰, and cracks, until cracks appear, causing fire (temperature) leakage, reducing the use effect and service life of the high-temperature furnaces, and causing the working environment to become harsh.

[0004] The current high-temperature resistant coating materials generally need to be applied manually during construction, and when cracks or cracks appear in the furnace lining, they can only be applied on the crack surface. It is difficult to effectively fill and paint the inside of the crack. After painting, the coating will shrink when it undergoes high-temperature sintering again, resulting in poor gap repair effect. The same crack needs to be repaired and painted repeatedly, the construction efficiency is low, and the construction effect needs to be improved. Summary of the invention

[0035] Embodiment 1: refer to Figure 1-3 , a filler comprising a component A and a component B; Component A is the main agent, and component B is the adhesive; the mass ratio of component A to component B is 9:1; Component A includes the following components by weight: 2 parts of methyl cellulose, 1.5 parts of talc, 21 parts of alumina powder, 6 parts of ceramic fiber, 1 part of silicone oil, 58.3 parts of diluent, and 0.2 parts of visual agent; component B includes by weight: 10 parts of silica sol; the diluent is water, and the visual agent is green pigment.

[0036] Component A also includes a mass component: 20 parts of epoxy resin / molybdenum disulfide compound, and the mass ratio of epoxy resin to molybdenum disulfide in the epoxy resin / molybdenum disulfide compound meets 240:1.

[0037] In order to achieve the purpose of rapid sintering, talcum powder is used as a solid lubricant with a particle size of 320 mesh, and alumina powder is used as a sintering refractory carrier with a particle size of 320 mesh.

[0038] The mass ratio of component A:component B can be 9:0.5, 9:0.6, 9:0.7, 9:0.8, 9:0.9, 9:1, 9:1.1, 9:1.2, 9:1.3, 9:1.4, 9:1.5; the mass ratio of epoxy resin and molybdenum disulfide in the epoxy resin / molybdenum disulfide composite can be 240:0.8, 240:0.9, 240:1, 240:1.1, 240:1.2, 240:1.3, 240:1.4, 240:1.5.

[0039] The preparation method of the epoxy resin / molybdenum disulfide composite is as follows: in the first step, molybdenum disulfide is pretreated, an appropriate amount of molybdenum disulfide powder is weighed and added to an autoclave, and then an appropriate amount of 2.5M butyl lithium n-hexane solution is added; the autoclave is filled with argon and sealed, and then placed in an oven at 90°C for heating for 12 hours; the obtained product is filtered and washed with n-hexane for 5 times; the vacuum-dried product is then hydrolyzed in an appropriate amount of water, and ultrasonically treated at room temperature for 4 hours, thereby obtaining a monolayer molybdenum disulfide sol suspension; In the second step, the molybdenum disulfide sol suspension obtained in the first step is adjusted to neutral with dilute hydrochloric acid, centrifuged and washed five times with distilled water, the molybdenum disulfide solid content is determined, the molybdenum disulfide mixture is washed with ethanol and centrifuged five times, and then washed twice with acetone, and finally acetone is used as a solvent to preserve the molybdenum disulfide after opening, and heated in an oven for 24 hours to obtain the opened molybdenum disulfide; The third step is to weigh an appropriate amount of molybdenum disulfide and add it to an appropriate amount of acetone, and ultrasonically treat it for 2 hours to form a uniform dispersion; then weigh an appropriate amount of epoxy resin and polypropylene glycol diglycidyl ether and add them to the above dispersion, and perform high-speed mechanical stirring and ultrasonic treatment at 40°C for 2 hours to form a uniform mixture; then transfer the above mixture to a 120°C oil bath environment, vacuum and high-speed stirring for 2 hours to remove acetone in the mixture; after the above mixture is cooled to room temperature, vacuum ultrasonic stirring is performed for 5 minutes; bubbles are removed under vacuum conditions, poured into a homemade polytetrafluoroethylene mold, cured at 75°C for 2 hours and then cured at 120°C for 8 hours, then cooled to room temperature, and demolded to obtain an epoxy resin / molybdenum disulfide composite.

[0040] Specifically, by adding epoxy resin / molybdenum disulfide composite to the filler of the present scheme, the thermal and mechanical properties of the filler can be improved, so that the filler of the present scheme has better bonding strength and tensile strength in a high temperature environment, and can further reduce the cracks and cracks in the kiln lining. The reasonable addition amount of molybdenum disulfide is verified by comparative experiments. The comparative experiments are as follows: Under the premise that the other groups of the present formula are classified to have the same quality, the molybdenum disulfide content of the control group is set to 0, the molybdenum disulfide content in experimental group 1 is 0.3wt%, the molybdenum disulfide content in experimental group 2 is 0.6wt%, the molybdenum disulfide content in experimental group 3 is 0.9wt%, the molybdenum disulfide content in experimental group 4 is 1.2wt%, and the molybdenum disulfide content in experimental group 5 is 1.5wt%; the finished filler is obtained by stirring with the equipment recorded in this scheme, and the experimental results are as follows:

[0041] The above experimental results show that the tensile strength, tensile modulus, elongation at break and bonding strength are all improved by adding molybdenum disulfide compared with not adding molybdenum disulfide; and further show that when the content of molybdenum disulfide reaches 0.6wt%, the various properties of the filler basically reach the optimal level, and when the amount of molybdenum disulfide increases, the various performance indicators of the filler gradually decrease, and when the content of molybdenum disulfide is greater than 1.2, the tensile strength, tensile modulus and elongation at break of the filler are all lower than those of the control group, that is to say, the addition of molybdenum disulfide will have a counter-effect, but the bonding strength at 1600° is still higher than that of the control group; therefore, when the content of molybdenum disulfide is 0.6wt%, the various performance indicators of the filler reach the optimal level, which helps to improve the mechanical and thermal properties of the filler.

[0042] Through reasonable improvements, this formula not only improves the mechanical properties of existing high-temperature fillers and improves various indicators of the fillers, but also enables the furnace lining to automatically repair tiny cracks in a high-temperature environment and reduce the probability of cracks. The viscosity is moderate and crack repair construction can be carried out through the production equipment of this solution.

[0043] Specifically, by adding an epoxy resin / molybdenum disulfide composite to the filler, the molybdenum disulfide contained therein has a high melting point and can melt in a high temperature environment of 2100 degrees, melting from a solid state to a molten state. Especially for coating fillers in high-temperature furnaces, when they are applied to the cracks and then burned at high temperature, after the water evaporates, talcum powder is used as a lubricant and silica sol is used as an adhesive. After the filler coating is initially solidified, due to thermal expansion and contraction, and after the water evaporates, tiny cracks will be generated, which are invisible to the naked eye. Over time, the cracks become cracks and cracks. However, after adding molybdenum disulfide, the molybdenum disulfide can melt into a molten state at a high temperature of 2136 degrees, increase in volume, and have a certain fluidity. It can carry silica sol, alumina powder, and ceramic fiber to move a small distance, and can well fill cracks that are invisible to the naked eye, thereby achieving the purpose of automatic repair of tiny cracks in the furnace lining; the service life of the furnace lining is improved, and the number of maintenance times can be reduced, saving maintenance costs.

[0046] The homogenizer 1 8 and the homogenizer 2 9 are provided with a transition tube body 92, which is a cylindrical structure. One end of the transition tube body 92 is connected to the homogenizer 2 9, and the other end is rotatably connected to the homogenizer 1 8.

[0047] Specifically, the production equipment provided by the present technical solution can achieve the purpose of production at any time and use at any time during production, and can well prevent the produced filler from being bonded and solidified due to long stirring time, thereby affecting normal use; the provided storage bin 1 4 and storage bin 2 5 are respectively used to place component A and component B. During production, equal proportions of materials are placed in the shell 1, and the stirring teeth are driven by the first electrode to rotate for stirring. After stirring, the materials are transported to the feed pipe 7 through the provided Jiaolong conveyor, and are sprayed out through the homogenizer 1 8, the homogenizer 2 9 and the discharge pipe 10. The discharge pipe 10 is movably connected to the homogenizer 2 9 by screws, which is convenient for cracks of different widths. Replace the discharge pipe 10 with different diameters; use the storage bin 1 4 and the storage bin 2 5 provided in the equipment to store the adhesive tube and other raw materials separately, and can mix them in time when using, which can effectively prevent the prepared filler from being bonded and solidified due to too long construction time, and is more convenient for construction; through the movable discharge pipe 10, replacing the discharge pipe 10 with different diameters is convenient for repairing cracks of different widths, so that the discharge pipe 10 can penetrate into the cracks for construction and filling. Compared with the traditional manual construction method, it not only improves the construction efficiency, but also can be constructed from the inside of the cracks, so that the paint can be completely filled in every corner of the cracks, and the filling effect is better.

[0048] Specifically, the homogenizing member 1 8 and the homogenizing member 2 9 can be provided to fully mix the material output from the feed pipe 7, thereby improving the dispersion of the filler. Because when the material passes through the feed pipe 7, the alumina powder, talcum powder, and ceramic fiber have high density and gravity, and will be deposited in the lower layer of the feed pipe 7. The transportation speed is relatively slow, resulting in poor dispersion of the filler. Finally, the filler ratio discharged from the discharge pipe 10 changes, affecting the overall performance of the filler. Therefore, by providing the homogenizing member 1 8 and the homogenizing member 2 9, the filler passing through the feed pipe 7 can be fully re-mixed to prevent stratification and sedimentation, thereby ensuring the dispersion of the discharge material in the discharge pipe 10 and improving the construction performance of the filler. The homogenizing process of the homogenizing member 8 is as follows: a plurality of disks 81 are arranged at intervals on the inner wall of the homogenizing member 8, the outer circumference of the disk 81 is connected to the inner wall of the homogenizing member, a central hole 82 is arranged at the center of the disk 81, and a homogenizing cavity 83 is formed between two adjacent disks 81. When the upstream fluid material passes through the central hole 82, it is filled in the homogenizing cavity 83. The material near the edge of the homogenizing cavity 83 is blocked by the disk 81, and the material is blocked by the disk 81. Due to the inertia, a reverse flow is formed. The reverse flow of the material is opposite to the direction of the subsequent material entering from the central hole 82. After the two fluids meet, a vortex is formed in the homogenizing cavity 83. The material in the lower layer is mixed with the material in the upper layer by the vortex. The material in the layer is stirred to form a stirring effect, so that the liquid filler has better dispersion and more uniform mixing; and by limiting the relationship between the radius R of the homogenizing member 8, the vertical distance d1 from the edge of the disk 81 to the side wall of the middle hole 82, and the distance d2 from the center of the middle hole 82 to the side wall of the middle hole, the diameter of the middle hole 82 becomes smaller, which can increase the flow rate of the material in the middle hole 82, and can better form a vortex, and the vortex speed is faster and the mixing effect is better; and through the concave setting of the disk 81, according to the vortex theory, the speed and size of the vortex are controlled by controlling the concave curvature of the disk 81, that is, the radial extension line at the center of the middle hole 82 and the connecting line between the center of the middle hole 82 and the outer peripheral edge of the disk 81. The smaller angle between the disk 81 and the disc 81 helps to increase the rotation speed and uniformity of the vortex, further improve the mixing effect of the materials, and ensure that various materials are fully mixed; in addition, according to the law of conservation of energy, the disk 81 has a certain concave curvature, which can reduce the flow resistance and pressure loss, but if the concave curvature is too large, it will lead to insufficient reverse water flow power, affecting the formation and stability of the vortex; therefore, by limiting the angle θ between the radial extension line at the center of the middle hole 82 and the connecting line between the center of the middle hole 82 and the outer peripheral edge of the disk 81 to meet 5°-23°, that is, the concave curvature of the disk 81, it can well ensure the speed and size of the vortex and ensure the mixing effect of various materials.
