Description

Technical Field

[0001] This utility model belongs to the technical field of hollow fiber addition for mixing and stirring of clay rollers, and specifically relates to a dispersible feeding device for hollow fibers in clay. Background Technology

[0002] Based on moisture content, taphole clay can be divided into hydrated taphole clay and anhydrous taphole clay. The formula of taphole clay mainly consists of aggregates, powders, binders, and additives. Anhydrous taphole clay uses tar or resin as a binder and high-alumina bauxite, silicon carbide, etc. as aggregates. It has excellent high-temperature strength and corrosion resistance and is suitable for large high-pressure blast furnaces.

[0003] Under the process of sealing the blast furnace taphole with anhydrous taphole clay, hollow fibers uniformly dispersed in the anhydrous taphole clay melt first when the temperature of the anhydrous taphole clay is between 120℃ and 150℃, forming channels inside the clay and improving its high permeability. Simultaneously, the addition of hollow fibers to the anhydrous taphole clay, under the same conditions, causes the temperature of the anhydrous taphole clay to continuously rise. At the 120℃~150℃ temperature range, the melting of the hollow fibers forms channels for discharging volatile components of the tar binder. When the temperature reaches 1300℃~1400℃, the metallic silicon (in a reducing atmosphere) and carbon elements in the formula form in-situ deposited silicon nitride or silicon carbide fillers, which fill the channels formed by the melting of the hollow fibers, improving the density of the anhydrous taphole clay. In addition, hollow fibers are added to the anhydrous taphole mud. Under the process of sealing the taphole of the blast furnace with anhydrous taphole mud, the pores formed by the melting of the hollow fibers are used to discharge the volatiles produced by the tar binder when the temperature of the anhydrous taphole mud is 120℃~150℃. This effectively eliminates the phenomenon of damp mud in the anhydrous taphole mud and prevents the risk of explosion caused by the anhydrous taphole mud.

[0004] In existing technologies, adding hollow fibers (typically 1.5mm to 3.5mm in length) to anhydrous clay is done by blowing air into the raw material mixer during the mixing stage. However, for bundled hollow fibers (formed by electrostatic interactions between the fibers), air blowing alone is insufficient to completely disperse them, resulting in poor dispersion of the hollow fibers in the anhydrous clay and directly affecting its permeability and density. To address these shortcomings in existing technologies, the inventors have developed a hollow fiber dispersion feeding device for clay, effectively resolving the aforementioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a dispersing feeding device for hollow fibers used in clay. The structure of this utility model is scientifically and rationally designed. Through the rotational cooperation of the rotary kneading cylinder and the kneading texture, the kneading dispersion of bundled hollow fibers is achieved. This utility model solves the technical problem that it is difficult to completely disperse bundled hollow fibers by simply blowing air.

[0006] The technical solution adopted in this utility model is as follows: a dispersing feeding device for hollow fibers used in tapping clay, comprising a hopper and a cylinder. The hopper is fixedly disposed at the upper part of the cylinder, which is a hollow cylindrical shape. An upper flange is fixedly disposed near the upper part of the outer wall of the cylinder, and a lower flange is fixedly disposed at the bottom of the upper flange, which is fixed to the outer wall of the cylinder. A suspension and dispersion chamber is fixedly disposed at the lower center of the cylinder, and is a hollow shape with openings at the top and bottom. Blowing holes are opened at equal angles around the outer wall of the cylinder, and are located at the bottom of the upper flange, with the blowing holes being inclined through holes. A blowing mechanism for blowing air into the cylinder is installed on the blowing holes. Kneading textures are uniformly fixedly disposed around the upper inner wall of the cylinder, and the kneading textures are used for kneading and dispersing. The kneading and dispersing cylinder is fixedly located at the upper part of the cylinder body. A rotating shaft is fixedly located at the center of the kneading and dispersing cylinder, and the rotating shaft runs vertically through the kneading and dispersing cylinder and extends to the upper and lower parts of the center of the kneading and dispersing cylinder. There are two fixed plates: fixed plate one and fixed plate two. Fixed plate one is fixedly located at the bottom of the kneading and dispersing cylinder, and its outer circumferential wall is fixed to the inner wall of the cylinder body. Fixed plate two is located at the bottom of fixed plate one, and its outer circumferential wall is fixed to the inner wall of the cylinder body. A slewing bearing is fixedly located at the center of fixed plate one. The bottom of the rotating shaft is installed in the inner ring of the slewing bearing and extends to the lower part of fixed plate one. The drive motor is installed at the center of fixed plate two, and the power output shaft of the drive motor is fixedly connected to the bottom end of the rotating shaft.

[0007] The upper flange and the lower flange are fixedly connected by bolts.

[0008] The blowing and spraying mechanism includes a bent pipe installed in the blowing and spraying hole. A bent pipe flange is fixedly installed on the outer end face of the bent pipe. One end flange of the solenoid valve is fixedly connected to the bent pipe flange. A straight pipe is set outside the solenoid valve. A straight pipe flange is fixedly installed on the inner end face of the straight pipe. The straight pipe flange is fixedly connected to the other end flange of the solenoid valve.

[0009] The end face of the bent pipe extending into the cylinder is flush with the inner wall of the cylinder.

[0010] The straight pipe is fixedly connected to the gas output end of the air compressor, and the solenoid valve is fixedly connected to the delay controller. The delay controller is used to control the intermittent blowing opening and closing action of the solenoid valve.

[0011] The kneading and dispersing cylinder includes an upper cone, which is fixedly disposed on the upper part of the middle cylinder, and a lower cone, which is fixedly disposed on the lower part of the middle cylinder. The diameter of the bottom surface of the upper cone is equal to the diameter of the middle cylinder, and the diameter of the upper end surface of the lower cone is equal to the diameter of the middle cylinder. Kneading ridges are uniformly and equidistantly fixedly disposed on the circumferential outer wall of the middle cylinder, and the kneading ridges uniformly fixedly disposed on the upper inner wall of the middle cylinder are radially corresponding to each other.

[0012] The length of the upper truncated cone is less than the length of the lower truncated cone, and the upper truncated cone, the lower truncated cone, and the intermediate cylinder are arranged vertically concentrically.

[0013] A gap is reserved between the uniformly and equidistantly fixed kneading ridges on the outer circumference of the intermediate cylinder and the uniformly fixed kneading ridges on the upper inner wall of the cylinder.

[0014] The fixing plate includes a fixing plate body, which is disc-shaped. A mounting hole is opened in the center of the fixing plate body, and fan-shaped through holes are evenly arranged at equal angles around the center of the mounting hole.

[0015] The fan-shaped through holes of the first fixed plate and the fan-shaped through holes of the second fixed plate are arranged vertically in correspondence, and the mounting holes of the first fixed plate and the second fixed plate are arranged concentrically vertically.

[0016] The slewing bearing is installed in the mounting hole of the first fixed plate, the drive motor is installed at the bottom of the second fixed plate, and the power output shaft of the drive motor extends through the mounting hole of the second fixed plate to the upper part of the second fixed plate.

[0017] The working process of this hollow fiber dispersing feeding device for clay is as follows: While the clay raw material is being mixed in the raw material mixer, the operator places the hollow fiber to be added to the clay raw material into the feeding hopper. At the same time, the air compressor, the solenoid valve of the blowing mechanism, and the drive motor are turned on. Under the rotation of the drive motor, the rotational power is transmitted to the rotating shaft through the power output shaft of the drive motor. The rotating shaft rotates around the slewing bearing as the rotation center, driving the upper cone, middle cone, and lower cone of the kneading and dispersing cylinder to rotate at a constant speed. At this time, the kneading ridges on the outer circumference of the middle cone and the kneading ridges on the upper part of the cylinder produce a rotating kneading action, which can knead the bundled hollow fibers in the feeding hopper. Hollow fiber kneading and dispersion: As the kneading and dispersion cylinder continues its rotating kneading motion with the kneading grooves on the upper part of the cylinder, the kneaded and dispersed hollow fibers pass through the gap between the kneading and dispersion cylinder and the cylinder body, entering the position of the lower cone. At this time, the high-pressure gas blown out by the curved pipe of the blowing mechanism blows the dispersed hollow fibers to the area around the lower cone. Instantly, the dispersed hollow fibers are blown into the suspension dispersion chamber through the fan-shaped through holes of fixed disk one and fixed disk two, forming an instantaneous suspension dispersion state. Finally, the hollow fibers are blown into the interior of the raw material mixer through the bottom opening of the suspension dispersion chamber. During the process of mixing the raw material mud in the raw material mixer, the dispersed hollow fibers and the raw material mud are thoroughly mixed evenly.

[0018] The beneficial effects of this utility model are as follows: by setting up a hopper, cylinder, suspension dispersion chamber, blowing hole, blowing mechanism, kneading texture, kneading dispersion cylinder, rotating shaft, fixed disk one, fixed disk two, rotary bearing and drive motor, the uniform rotation of the kneading dispersion cylinder combined with the friction and kneading force between the kneading textures realizes the kneading and dispersion of bundled hollow fibers, improves the uniform dispersion of hollow fibers in anhydrous tapping clay, thereby improving the air permeability and density of anhydrous tapping clay.

[0025] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model provides a dispersible feeding device for hollow fibers used in gun clay:

[0027] like Figure 1 , 2As shown in Figures 3 and 4, the upper flange 4 is fixedly installed on the outer wall of the cylinder 3 near the upper part, and the lower flange 5 is fixedly installed at the bottom of the upper flange 4, with the lower flange 5 fixed to the outer wall of the cylinder 3. Through the arrangement of the upper flange 4 and the lower flange 5, the cylinder 3 can be fixed to the center of the upper cover of the raw material mixer 1 using the lower flange 5. This serves two purposes: firstly, it provides a fixed support for the cylinder 3; secondly, it seals the mounting holes of the upper cover of the raw material mixer. The upper flange 4, in conjunction with the lower flange 5 and the connecting action of the screws, enhances the supporting strength of the cylinder 3 provided by the upper flange 4 and the lower flange 5.

[0028] like Figure 2 , 3 As shown in Figure 4, the cylinder 3 is a hollow cylindrical shape, and the suspension and dispersion cavity 6 is fixedly located at the lower center of the cylinder 3. The suspension and dispersion cavity 6 is a hollow shape with openings at the top and bottom. Through the arrangement of the cylinder 3, the kneading texture 9 and the kneading ridge 104 on the middle cylinder 103 of the kneading and dispersion cylinder 10 are rotated together to achieve the kneading and dispersion action of the bundled hollow fibers. The internal cavity of the cylinder 3 is both a rotating cavity for the kneading and dispersion action and an air blowing and conveying cavity for the hollow fibers after kneading and dispersion.

[0029] like Figure 2 , 3 As shown in Figure 4, the blow-off holes 7 are opened at equal angles around the outer wall of the cylinder 3. The blow-off holes 7 are located at the bottom of the upper flange 4 and are inclined through holes. The blow-off mechanism 8 for blowing air into the cylinder 3 is installed on the blow-off holes 7. The blow-off holes 7 opened at equal angles around the outer wall of the cylinder 3 provide installation space for the blow-off mechanism 8. By setting up multiple blow-off mechanisms 8, high-pressure gas can be blown evenly into the interior of the cylinder 3. On the one hand, it plays a role in uniformly blowing air into the hollow fibers that have been kneaded and dispersed. On the other hand, the multiple blow-off mechanisms 8 form a confluence of high-pressure gas, which plays a role in blowing and conveying air into the hollow fibers.

[0030] like Figure 2As shown, the kneading texture 9 is uniformly fixed around the upper inner wall of the cylinder 3. The kneading and dispersing cylinder 10 is fixedly installed in the upper part of the cylinder 3. A rotating shaft 11 is fixedly installed at the center of the kneading and dispersing cylinder 10. The rotating shaft 11 vertically penetrates the kneading and dispersing cylinder 10 and extends to the upper and lower positions of the center of the kneading and dispersing cylinder 10. The fixing plate 12 is divided into a fixing plate one 13 and a fixing plate two 14. The fixing plate one 13 is fixedly installed at the bottom of the kneading and dispersing cylinder 10. The outer circumferential wall of the fixing plate one 13 is fixed to the inner wall of the cylinder 3. The fixing plate two 14 is installed at the bottom of the fixing plate one 13. The outer circumferential wall of the fixing plate two 14 is fixed to the inner wall of the cylinder 3. The slewing bearing 15 is fixedly installed at the center of the fixing plate one 13. The bottom of the rotating shaft 11 is installed in the inner ring of the slewing bearing 15 and extends to the lower part of the fixing plate one 13. The drive motor 16 is installed at the center of the fixing plate two 14. The power output shaft of the drive motor 16 is fixedly connected to the bottom end of the rotating shaft 11.

[0031] The above-mentioned arrangement of the kneading texture 9, the kneading and dispersing cylinder 10, the first fixed plate 13, the second fixed plate 14, the slewing bearing 15, and the drive motor 16, under the rotational action of the drive motor 16, transmits the rotational power to the rotating shaft 11 through the power output shaft of the drive motor 16. The rotating shaft 11 drives the kneading and dispersing cylinder 10 to rotate at a uniform speed with the slewing bearing 15 as the rotation center. At this time, the kneading ridges 104 set on the outer circumferential wall of the intermediate cylinder 103 and the kneading texture 9 on the upper part of the cylinder 3 generate a rotating kneading action, which can play a kneading and dispersing role on the bundled hollow fibers.

[0032] like Figure 2 , 3 As shown in Figure 4, the blowing and spraying mechanism 8 includes a bent pipe 81, which is installed in the blowing and spraying hole 7. A bent pipe flange 83 is fixedly installed on the outer end face of the bent pipe 81. One end flange of the solenoid valve 82 is fixedly connected to the bent pipe flange 83. A straight pipe 84 is located outside the solenoid valve 82. A straight pipe flange 85 is fixedly installed on the inner end face of the straight pipe 84. The straight pipe flange 85 is fixedly connected to the other end flange of the solenoid valve 82.

[0033] The aforementioned arrangement of the bend 81, solenoid valve 82, bend flange 83, straight pipe 84, and straight pipe flange 85, along with the fixed connection between the solenoid valve 82 and the delay controller, allows the intermittent blowing action of the solenoid valve 82 to be controlled by the delay controller. This intermittent blowing action is achieved at the position of the lower cone 102 of the kneading and dispersing cylinder 10, which can blow the kneaded and dispersed hollow fibers into the suspension and dispersion chamber 6. On the one hand, it plays a role in uniformly blowing air onto the kneaded and dispersed hollow fibers; on the other hand, it uses multiple blowing and spraying mechanisms 8 to form a confluence of high-pressure gas, which plays a role in blowing and conveying the hollow fibers.

[0034] like Figure 4As shown, the end face of the bent tube 81 that extends into the cylinder 3 is flush with the inner wall of the cylinder 3. The main purpose of the above setting is to improve the smoothness of the end face of the bent tube 81 that extends into the cylinder 3 and the inner wall of the cylinder 3, which can effectively prevent the hollow fibers that have been kneaded and dispersed from getting stuck at the contact point between the end face of the bent tube 81 and the inner wall of the cylinder 3.

[0035] like Figure 3 , 5 As shown, the kneading and dispersing cylinder 10 includes an upper cone 101, which is fixedly disposed on the upper part of the intermediate cylinder 103, and a lower cone 102, which is fixedly disposed on the lower part of the intermediate cylinder 103. The bottom diameter of the upper cone 101 is equal to the diameter of the intermediate cylinder 103, and the upper end diameter of the lower cone 102 is equal to the diameter of the intermediate cylinder 103. Kneading ridges 104 are uniformly and equidistantly fixedly disposed on the circumferential outer wall of the intermediate cylinder 103, and the kneading ridges 9 uniformly fixedly disposed on the upper inner wall of the intermediate cylinder 103 are radially corresponding to each other.

[0036] The aforementioned arrangement of the upper cone 101 utilizes the structure of its inclined transition surface to guide the hollow fibers toward the inner wall of the cylinder 3 during its rotation, while also preventing the hollow fibers from accumulating in the center of the upper cone 101.

[0037] The aforementioned arrangement of the lower truncated cone 102, with the cone length of the upper truncated cone 101 being less than that of the lower truncated cone 102, and the upper truncated cone 101, lower truncated cone 102, and intermediate cylinder 103 being vertically concentric, serves two main purposes: firstly, by utilizing the longer cone length of the lower truncated cone 102, a larger blowing space is provided for the hollow fibers after kneading and dispersing; secondly, the lower truncated cone 102 plays a guiding role during the blowing of the hollow fibers.

[0038] The aforementioned kneading ridges 104 provided on the outer circumferential wall of the intermediate cylinder 103, combined with the friction and kneading action of the kneading ridges 9 on the upper part of the inner wall of the cylinder 3 under rotation, on the one hand, knead and disperse the bundled hollow fibers, and on the other hand, rotate and transport the hollow fibers downward.

[0039] like Figure 3 and 5 As shown, the fixed disk 12 includes a fixed disk body 121, which is disc-shaped. A mounting hole 122 is provided in the center of the fixed disk body 121, and fan-shaped through holes 123 are evenly arranged at equal angles around the center of the mounting hole 122. The fan-shaped through holes 123 of the fixed disk one 13 and the fan-shaped through holes 123 of the fixed disk two 14 are arranged vertically correspondingly, and the mounting holes 122 of the fixed disk one 13 and the fixed disk two 14 are arranged vertically concentrically.

[0040] The aforementioned fixing plate 13 provides rotational support for the rotation of the upper cone 101, lower cone 102, and intermediate cylinder 103. The aforementioned fixing plate 14 provides a mounting position for the drive motor 16, serving to fix and support the drive motor 16.

[0041] The aforementioned fan-shaped through-holes 123 provide a channel for the hollow fibers after kneading and dispersing. On the other hand, the multiple fan-shaped through-holes 123 can increase the blowing pressure of the hollow fibers, thereby improving the suspension and dispersion effect in the suspension and dispersion chamber 6.

[0042] like Figure 1-5 As shown, the working process of this hollow fiber dispersing feeding device for gun clay is as follows: When the gun clay raw material is being stirred in the raw material mixer, the operator places the hollow fiber to be added to the gun clay raw material into the feeding hopper 2, and at the same time turns on the air compressor, the solenoid valve 82 of the blowing mechanism 8, and the drive motor 16; under the rotation of the drive motor 16, the rotational power is transmitted to the rotating shaft 11 through the power output shaft of the drive motor 16. The rotating shaft 11 drives the upper cone 101, the middle cylinder 103, and the lower cone 102 of the kneading and dispersing cylinder 10 to rotate at a constant speed with the slewing bearing 15 as the rotation center. At this time, the kneading ridges 104 on the outer circumference of the middle cylinder 103 and the kneading ridges 9 on the upper part of the cylinder 3 generate a rotating kneading action, which can dissipate the hollow fiber in the feeding hopper 2. The bundled hollow fibers are kneaded and dispersed. As the kneading and dispersing cylinder 10 and the kneading grooves 9 on the upper part of the cylinder 3 continue to rotate and knead, the kneaded and dispersed hollow fibers enter the position of the lower cone 102 through the gap between the kneading and dispersing cylinder 10 and the cylinder 3. At this time, the high-pressure gas blown out by the curved pipe 81 of the blowing and spraying mechanism 8 blows the dispersed hollow fibers to the position around the lower cone 102. Instantly, the dispersed hollow fibers are blown into the suspension dispersion chamber 6 through the fan-shaped through holes 123 of the fixed disk 13 and the fixed disk 2 14, forming an instantaneous suspension dispersion state. Finally, the hollow fibers are blown into the interior of the raw material mixer 1 through the bottom opening of the suspension dispersion chamber 6. During the process of the raw material mixer 1 mixing the gun clay raw material, the dispersed hollow fibers and the gun clay raw material are fully mixed evenly.

[0043] Various modifications to the above embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
