Description

  The present invention includes, for example, a wind box of a sintering machine for producing sintered ore as a raw material for a blast furnace, a cooling machine for cooling high-temperature sintered ore, and a pallet truck-like endless continuous transfer that moves on a rail as well as these. The present invention relates to a sealing device in a facility where the lower surface of a carriage passes through a portion that separates a place where atmospheric pressure and atmospheric pressure or less slide, and the flow of air or gas needs to be blocked.

  The two or more pallet trucks run endlessly on the rail while adjacent to each other, and the windbox placed below the pallet creates a negative pressure below the atmospheric pressure and continuously loads the iron ore loaded on the pallet truck. In a sintering machine that sinters, the end of the wind box group forming the negative pressure and the area on the atmospheric pressure side are shut off, and sealing is performed so that air that is ineffective for firing or cooling does not flow into the wind box. Or it is important in order to reduce the electric power of the exhaust fan which exhausts the air required for cooling.

  For example, in Patent Document 1, the pallet carriage enters the negative pressure wind box group of the sintering machine from the atmospheric pressure side, and the exhaust side sealing device that exits from the negative pressure wind box group after firing to the atmospheric pressure side. Has been proposed. In this sealing device, a liner placed on the base plate to slide with the lower surface of the pallet carriage is brought into contact with the lower side of the pallet truck by following the distortion in the pallet width direction on the bottom surface of the pallet truck by a lifting mechanism using heavy cones. This is a structure to prevent.

  The sealing device proposed in Patent Document 1 is a push-up mechanism using a heavy cone in the direction of the cart width in order to follow the distortion in the cart width direction perpendicular to the endless continuous traveling direction on the bottom surface of the pallet cart of the base plate. I was trying to express the deflection. However, the above-mentioned push-up mechanism in which the point of action of the force to be pushed up is partial due to the limitations of the mechanical space, it was not possible to push up with a uniform surface pressure, so a gap with the bottom surface of the pallet may partially occur. The air leak could not be prevented sufficiently.

  Moreover, although the pressure partition is formed using the expansion joint, since a space is formed between the uneven portion of the expansion joint and the wear bar support, the space is filled with a heat insulating material. However, since the upper end of the heat insulating material is flush with the upper end of the wear bar support, it is inevitable that a small space is formed. The place where this small space is formed is a place where air is constantly flowing from the atmospheric pressure side to the negative wind box side at a high speed and flows in with the nearby sintered dust. The wear and wear of the small surface appearing at the upper end becomes severe. Therefore, there is a problem that the small space gradually becomes larger, eventually all the heat insulating material is lost, and then the expansion joint itself is damaged due to wear.

  Patent Document 2 proposes a structure in which the dead plate surface is flexible so that it can follow the deformation of the pallet carriage. The one proposed in Patent Document 2 is a system in which the lower periphery of the dead plate surface is supported by an elastic material, and the pressure fluid is supplied from the pressure fluid supply means and sealed to follow the lower surface of the sintering pallet. It is.

  However, the space for sealing the pressure fluid is sealed, and although the periphery of the contact surface can be expanded and contracted, it is constrained by the expansion and contraction material. In addition, since the vicinity of the width direction end of the sintered pallet does not adhere as closely as the central portion, there is a problem that air leakage occurs at that location. Furthermore, the method of sealing with the wear bar support at the end in the pallet width direction is not specified, there is no explanation for the wear of the elastic material, and it is predicted that it will be easily worn and broken. In addition, if the high-temperature sintered ore powder falls and comes into contact with the elastic material, or if it flows on the surface of the elastic material at a high speed, the elastic material is immediately worn and torn. If the expansion / contraction material is torn, the sliding surface is lowered at a stretch and the gap with the lower surface of the sintering pallet is increased, which involves a risk that the sintering operation cannot be performed.

  In Patent Documents 3 and 4, sliding materials divided into a plurality of sheets in the width direction of the sintering pallet are supported using leaf springs, arranged in a plurality of rows in the pallet moving direction, and pressed against the lower surface of the sintering pallet. A structural sealing device has been proposed.

  However, this method has a structure in which the contact surface between the leaf spring both ends and the wear bar support has a gap or is slidable, so that air leakage cannot be prevented, and the sintering is accompanied by inflowing air. There is a problem that it is worn out in a short time by the mineral dust.

  Moreover, since the sliding material pressed against the lower surface of the sintered pallet is supported by a thin leaf spring in order to ensure its elasticity, there is a problem that a slight air leak causes wear and holes. Furthermore, since the plate springs are arranged in a plurality of rows in the traveling direction of the sintering pallet, a dust discharge hopper is required below the plate springs, which may cause problems in controlling dust discharge and maintaining the discharge device. . When the hopper is not installed, dust accumulates and the elastic performance by the leaf spring is fixed, and a fixed gap is formed between the lower surface of the sintered pallet, and there is a problem that air leakage cannot be prevented.

  Further, in Patent Document 5, the sliding material divided into a plurality of sheets in the width direction of the sintered pallet is supported by using a coil spring, so that the air leaks while pressing the sliding material on the lower surface of the sintered pallet. There has been proposed a sealing device for blocking the above.

  However, since the structure proposed in Patent Document 5 divides the sliding material into a plurality of sheets in the width direction of the sintered pallet, there is a gap between the sliding materials, and air leakage can be completely prevented. There is a problem that you can not.

  Patent Document 6 proposes a roller-type sealing device that makes rotational contact with the lower surface of the sintering pallet, but rotates the roller between the end surface of the rotating roller and the inner surface of the fixed-side wear bar support. A gap is necessary to make it happen. Therefore, there is a problem that air leakage occurs from this gap and wear occurs, and it cannot be used for a long time. Further, the roller cannot follow the strain in the width direction of the sintered pallet and cannot prevent air leakage.

  Patent Document 7 proposes a structure in which a surface that slides on the lower surface of the sintering pallet of the dead plate sealing device is supported by a leaf spring. However, there is a problem in that a gap for sliding the leaf spring is required between the wear bar support and the leaf spring on both ends in the width direction, so that air leakage occurs, and therefore wear occurs.

  Moreover, since the sealing structure proposed by patent document 8, 9 has comprised the sealing surface in the sliding surface divided | segmented into multiple sheets in the width direction of a sintering pallet, it prevents the air leak from a division part. There is a problem that can not be.

  That is, in the prior art, a surface that slides up and down following the distortion in the width direction of the pallet carriage and slides on the lower surface of the pallet, and prevents the air leakage while maintaining the function of the vertical movement, It was difficult to achieve both functions for maintaining performance. In particular, simultaneously seal the three surfaces of the vertical end of the windbox perpendicular to the direction of travel of the pallet carriage and the vertical surface of the dead plate on both ends in the pallet width direction in contact with the inner surface of the wear bar support parallel to the direction of travel. In addition, a sealing device that can move up and down has not been completed.

  The problem to be solved by the present invention is that, in the case of conventional sealing devices, it is difficult for both sealing devices to achieve both a function of preventing air leakage and a function of maintaining long-term performance.

The sealing device of the sintering machine wind box of the present invention,
In order to prevent air leakage as long as possible,
At the point where the lower surface of the endless continuous conveyance carriage constructed by adjoining a plurality of pallet trucks moving on the rail passes through the part that divides the area other than atmospheric pressure and atmospheric pressure, air or gas A sealing device for blocking flow,
A base plate configured to always press the surface against the lower surface of the endless continuous conveyance carriage is formed into a single membrane plate, and an abrasion-resistant liner is attached to the surface. Vertical plate materials are suspended and fixed on both sides in the width direction and the front end in the traveling direction.
Among these vertical plate members, a receiving member that supports the first vertical plate member that is suspended and fixed to the front end side in the traveling direction of the cart is installed on the wind box receiving beam that supports the wind box,
A wear liner support located below both sides of the carriage in the traveling direction is attached to the inner side surface parallel to the carriage traveling direction with a fixed liner having an uneven upper end surface, and the width direction of the carriage on the back surface of the base plate. On the outside of the second vertical plate suspended from both sides, a movable liner having a concavo-convex lower end surface fitted to the concavo-convex of the upper end surface of the fixed liner is attached,
Furthermore, it passes through the both liners from the inner side of the first vertical plate member to the fixed plate surface installed on the first vertical plate member side of the receiving beam of the wind box, and from the inner side of the second vertical plate member. The main feature is that a cloth-like member coated with a viscous paste-like substance is stretched on the atmospheric pressure side of the surface between the side surfaces of the wear bar support.

  In the sealing device for a sintering machine wind box according to the present invention, vertical plates are suspended and fixed on both sides in the width direction of the carriage and the front end side in the traveling direction on the back surface of the base plate, and installed on the receiving beam of the wind box from the inside of these vertical plates. Since a cloth-like member coated with a viscous paste-like substance on the atmospheric pressure side is stretched between the fixed plate surface and the side of the wear bar support, it is structured from the bottom surface of the seal mechanism. There is no leaking air.

  According to the present invention, there is no air leakage that structurally leaks from the lower surface of the seal mechanism. If a cloth-like member breaks and a wind leak occurs, it can be easily detected by the generated noise, so that repair can be done quickly and easily during operation. Thereby, there is less air leakage unnecessary for sintering, and power saving can be achieved.

It is a whole perspective view of the sealing device of the present invention installed in the supply side.

It is a principal part enlarged view of the trolley | bogie advancing direction of the sealing apparatus of this invention.

  In the present invention, the purpose of preventing air leakage as long as possible over a long period of time is to receive the windbox from the inside of the vertical plate material that is suspended and fixed to the both sides in the width direction of the carriage and the front end side in the traveling direction on the back surface of the base plate. This was realized by providing a cloth-like member coated with a viscous paste-like substance on the atmospheric pressure side between the fixed plate installed on the beam and the side of the wear bar support.

  Hereinafter, an embodiment in which the present invention is applied to a sealing device for a wind box of a sintering machine will be described with reference to FIGS.

  For example, as shown in FIG. 1, the sealing device 1 of the present invention is installed at a feed end and a discharge end of a sintering machine, and air is supplied from the lower surface of a pallet truck 2 that moves from the feed side to the discharge side. It is to prevent leakage. In FIG. 1, 3 indicates a wind box and 9 indicates an ignition furnace.

  The point to prevent the air from leaking is to improve the structure of the lower part of the base plate 11 constituting the surface of the sealing device 1 that slides on the lower surface of the pallet carriage 2 and to prevent the occurrence of almost no air leakage. Is to increase.

  Therefore, in this invention, it connects with the back surface side of the base plate 11 which can be moved up and down, and the fixed plate 8 installed in the wind box receiving beam 5 used as the end surface of the wind box 3 at right angles to the advancing direction of the pallet carriage 2 The first vertical plate 13a is sealed (see FIG. 6), and the second vertical plate 13b is connected to the inner surface of the wear bar support 7 on both sides in the width direction of the pallet carriage 2 and the back side of the base plate 11. The following configuration is adopted so that the seal (see FIG. 5) can be integrated integrally at the same time, and can follow the distortion in the width direction of the pallet carriage 2 shown by the imaginary line in FIG. 3 (b). ing.

  Reference numeral 11 denotes a base plate configured to always press the surface against the lower surface of the pallet carriage 2. In the present invention, the base plate 11 is composed of a single plate that is sufficiently thin (approximately 9 mm) so that it can be bent in the width direction of the pallet carriage 2 (see FIG. 3). A wear-resistant liner 12 is attached to the front surface, and vertical plate members 13a and 13b are suspended and fixed to the both sides in the width direction of the pallet carriage 2 and the front end side in the traveling direction, respectively. In addition, it is desirable that the wear-resistant liner 12 is divided and attached to a plurality of sheets in the width direction of the pallet truck 2 so that the base plate 11 is easily bent in the width direction of the pallet truck 2.

  Although the structure which always presses the surface of the baseplate 11 which attached the said abrasion-resistant liner 12 with respect to the lower surface of the pallet truck 2 is not specifically limited, The structure as shown in FIG. 6 is employ | adopted. For example, in FIG. 6, bell cranks 14 a are installed at two locations on the back side of the base plate 11 in the forward and backward directions of the pallet carriage 2 so as to be swingable up and down, and a heavy cone 14 b is attached to one end of the bell crank 14 a. The base plate 11 is pushed up by a roller 14c rotatably attached to the other end. In addition, the advancing direction of the pallet carriage 2 shown by the white arrow in FIG. 6 shows the thing in the sealing device of the wind box on the sintering machine feed side (the right side of FIG. 1), and the exhaust side (figure 1), the direction opposite to the white arrow in FIG. 6 is the traveling direction of the pallet carriage.

  Reference numeral 15 denotes a receiving member installed on a windbox receiving beam 4 that supports the windbox 3, and hangs down on the end face side of the windbox 3 in the direction perpendicular to the traveling direction of the pallet carriage 2 of the vertical plate members 13 a and 13 b. The fixed first vertical plate member 13a is supported from the wind box 3 side. The receiving member 15 can prevent the first vertical plate member 13a, the base plate 11 integrated with the first vertical plate member 13a, and the second vertical plate member 13b from being pulled into the wind box 3 due to negative pressure. In the drawing, the first vertical plate 13a movable up and down is supported by a rotatable roller 15a.

  In the case of the pressing mechanism having the above-described structure, there is no problem that the elasticity of the spring material changes due to the high temperature of the ore removal portion and the elasticity is lost, as in the case of pressing using the spring material. Further, the base plate 11 is composed of a sufficiently thin plate, has a rigidity that can sufficiently follow the bending of the lower surface of the pallet carriage, and does not restrain the periphery of the sliding surface with an elastic material, Seal plates (first vertical plate material 13a on the windbox side and second vertical plate material 13b on the wear bar support side) suspended from three surfaces below the sliding surface, and a cloth member for sealing, which will be described later, provided on the inside thereof 18a and 18b strongly prevent air leakage, so that the negative pressure in the wind box is uniformly applied to the atmospheric pressure side (lower part, back surface) of the sliding surface, and the base plate 11 is limited even if the push-up point by the heavy cone 14b is limited. Can be uniformly pressed against the lower surface of the pallet carriage 2.

  However, the pallet side seal bar 5 that blocks between the second vertical plate 13b suspended and fixed on both sides in the width direction of the pallet carriage 2 and both side surfaces (atmospheric pressure) in the width direction of the pallet carriage 2 and the wind box 3 (negative pressure). And between the surfaces formed by the wear bar 6 and the wear bar support 7 in parallel with both side surfaces in the width direction of the pallet carriage 2 and the base plate 11 and the vertical plate members 13a and 13b move up and down. The gap d1 is always necessary (see FIG. 4A).

  And since the leaked air which passes this clearance gap d1 is accompanied by the nearby sintered dust, wear of the location where the leaked air passes becomes intense. For this reason, the inventors have adopted the following structure in order to ensure durability by putting a wear-resistant liner on both sides of the gap d1, and to minimize or completely eliminate the amount of air leakage.

  Reference numeral 16 denotes a fixed liner attached to the inner side surface of the wear bar support 7 positioned below both sides of the pallet cart 2 in the direction of travel, parallel to the direction of travel of the pallet cart 2, and the upper end surface is formed to be uneven.

  Reference numeral 17 denotes a movable liner formed on the lower end surface thereof with a concave and convex portion that fits into the concave and convex portions formed on the upper end surface of the fixed liner 16, and is attached to the outside of the second vertical plate 13b on the back surface of the base plate 11. ing.

  As described above, the labyrinth structure in which the upper end surface of the fixed liner 16 and the lower end surface of the movable liner 17 installed in the gap are formed to have a concave-convex engagement with each other is more resistant to the flow than the straight air flow. Can be generated to reduce air leakage.

  At that time, when the grease supply ports 7a are provided at a plurality of locations on the wear bar support 7, and the periodic grease can be supplied from the outer surface (atmospheric pressure side) to the gap, the sealing device 1 movable up and down, The gap d2 (see FIG. 5 (a)) of the fixed wear bar support 7 keeps the durability against the wear and wear of the sealing device 1 high while always blocking the passage of air with filled grease. Vertical movement is possible.

  18a is a paste which is stretched between the inside of the first vertical plate 13a and the fixed plate 8 installed on the first vertical plate side of the windbox receiving beam 5 and is viscous on the atmospheric pressure side of the surface. This is a cloth-like member coated with a substance (see FIG. 6).

  Reference numeral 18b denotes a cloth-like member similar to the cloth-like member 18a, which is stretched from the inside of the second vertical plate member 13b to the side surface of the wear bar support 7 through both the liners 16 and 17 ( (Refer FIG.4 (b) and FIG.5 (a)).

  These cloth-like members 18a and 18b cover the inlets to flow into the gaps d2 and d3 existing between the movable part and the fixed part constituting the sealing device 1, thereby improving the sealing performance and completely preventing the air leakage. Can be blocked.

  As the cloth-like members 18a and 18b, for example, a cloth woven with stainless steel fibers, which has flexibility, heat resistance, and little fraying is employed. If it is a premise that frequent replacement is performed, a heat-insulating cloth having heat resistance may be adopted.

  Further, as the viscous paste-like substance to be applied to the atmospheric pressure side of the surfaces of the cloth-like members 18a and 18b, a sealing material such as a heat-resistant silicone sealant is sufficient. Heat resistant grease may be used. The paste is not particularly limited as long as it can maintain flexibility and has heat resistance.

  The atmosphere using this paste-like substance is not an atmosphere in which high-temperature processed materials such as sintered ore are conveyed on the atmospheric pressure side, but in the frame on the machine structure side of the sintering machine, Since it does not exceed 200 ° C. even in a high temperature atmosphere, commercially available materials can be used sufficiently.

  In the case of the above configuration, if a paste-like substance deteriorates due to secular change and cracks occur, or if the cloth-like members 18a, 18b are frayed and a leak occurs, repair from the inspection deck below easily. Can do.

  Further, if the cloth-like members 18a and 18b are integrated, the gap between the end surface on the wind box side (surface perpendicular to the traveling direction of the pallet cart 2), the wear bar support 7 and the sealing device 1 (the pallet cart 2 The three surfaces (both side surfaces in the width direction) are completely sealed, so that wind can be prevented from flowing into the gap on the wear bar support 7 side from both ends of the base plate 11. Moreover, the performance can be easily maintained.

  In the case of the above configuration, the remaining gap where air leakage occurs is only the gap between the lower surface of the pallet carriage 2 and the surface of the base plate 11 that slides and the seal bars 5 on both sides of the surface. The pressure difference is directly applied to the entire plate area. Therefore, since the base plate 11 is pressed against the lower surface of the pallet carriage 2 with a force several times the force pushed up by the heavy cone 14b, the degree of adhesion can be increased and the air leakage can be reduced. At that time, the pressing force is applied uniformly to the lower surface of the pallet carriage 2 because it is pressed by the surface. Furthermore, since the periphery of the sliding surface is not constrained by an elastic material or the like, the pallet width direction end can also be closely attached.

  In addition, since the pressure difference directly acts on the vertical surface on which the cloth-like members 18a and 18b coated with the paste-like substance are stretched, the metal plates such as the movable liner 17 and the wear bar support 7 also contact each other. Furthermore, the minute gap due to the distortion of the metal plate material is completely sealed by the cloth-like members 18a and 18b.

  By the way, the end of the windbox adjacent to the atmospheric pressure on the supply side and the discharge side of the windbox group of the sintering machine equipped with 90 pallet trucks 2 with a pallet width of 3.7m and a length of 1.5m. 1 each of the sealing devices 1 of the present invention were arranged and operated. During operation, the pressure in the windbox 3 was -18 kPa, and the temperature was 100 ° C on the supply side and 400 ° C on the discharge side. In addition, since the back surface side of the base plate 11 is open | released by air | atmosphere and there exists ventilation | gas_flowing, as atmospheric temperature, it is about 150 degreeC.

  As the fixed liner 16 and the movable liner 17 constituting the sealing device 1 of the present invention, dust-mixed air directly passes through and wear is significant, so a plate material having a hardened surface with high hardness is used.

  Further, as shown in FIGS. 2 and 3, the wear-resistant liner attached to the surface of the base plate 11 was divided into a plurality of sheets in the pallet width direction and attached in a staggered manner. As the wear-resistant liner, a steel plate with a hard coating was used in order to prevent wear due to a high-speed flow of dust.

  The length L in the pallet moving direction of the base plate 11 is that the frame structure of the pallet carriage 2 is generally composed of three to four beams 2a, and two of them must always be positioned on the base plate 11. However, the longer one increases the flow resistance and reduces the air leakage. Therefore, in the embodiment, the length L in the pallet traveling direction of the base plate 11 is 1.8 m, the width B in the pallet width direction is 3.5 m close to the interval between the inner side surfaces of the wear bar support, and the thickness t is 10 mm. The thickness t of the base plate 11 can be selected according to the bending allowance on the pallet truck side, and is determined by the amount and width of the bending.

  The cloth-like members 18a and 18b are made of stainless steel fiber cloth, and the paste-like substance is a commercially available heat-resistant silicon sealant. The grease supplied to the gap was heat resistant grease having heat resistance of about 200 ° C.

In the case of the above-described embodiment, the pushing force F of the base plate 11 is the pressure difference between the base plate 11 width 3.5 m × length 1.8 m × atmospheric pressure and the pressure of the wind box 3 (−18 kPa) 1.8 ton / m ² = 11.3 tons, a large pressing force can be obtained as compared with a conventional pushing force of 600 kg which is mechanically pushed up by providing six 100 kg heavy cones.

  The pushing force F of the base plate 11 at that time is received by the entire surface of the base plate 11 in the above embodiment, but in the conventional case, it is pushed up at several places where the weight of the heavy cone acts.

  Accordingly, the pressing force of the first vertical plate 13a in front of the pallet carriage 2 in the traveling direction is about the wind flow resistance in the conventional case, whereas in the case of the above-described embodiment, the height of the cloth-like member 18a is high. When the thickness is 0.3 m, the width (length B of the base plate 11 in the pallet width direction) is 3.7 m, the pressure difference is 18 MPa, and the loss due to the flow resistance due to slight air leakage on the sliding surface is 0.5, 1.8 MPa × 0.3 m × 3.7 m × 0.5 = 999 kg, and the pressing force of the seal surface expresses a pressing force several times or more in the upward direction or the traveling direction.

  In addition, it is also possible to use the push-up mechanism by the conventional heavy cone in combination with the push-up method by the pressure difference this time.
