Description of the invention: [Technical field to which the invention pertains] The invention of the present invention is generally directed to a distribution chute for use in a _ 政 political loading material distribution device, which is used for distribution in 3 grazing, for example, metallurgical reaction benefits And especially in one of the blast furnaces, the loose clothes in the closed casing are shaken. More specifically, the present invention relates to a dispensing chute having a chute body defining a passage with a curved portion that diverts bulk material from a first flow direction to a second flow In the direction, the bulk material flows into the inlet portion of the chute immediately after impinging on the chute along the first flow direction. The bulk material stream exits the chute outlet in the second flow direction. [Prior Art] In the specific case of the blast furnace, it has been found that the so-called "beU-less" type of charging equipment is widely used. Such charging equipment is disposed on the top of the furnace and includes a distribution device and has a distribution chute as an important component. The dispensing device is typically assembled to rotate the shoulder chute ' about an upright furnace axis and to pivot the chute about a vertical horizontal axis. During the beta charging process, the bulk filler falls vertically on the distribution chute, and the distribution chute distributes the material in the circumferential direction and the radial direction according to its rotation and pivoting position, so that it can be on the loading surface. Achieve any desired distribution pattern of the filling material. Due to the large amount of scattered material sliding through a distribution chute, the chute suffers from considerable grinding tv ^ XJ. Μ , Α ^ 田 ~ 锴, and must often be renewed or refurbished Chute replacement. You 丨i a , for example, from the European patent EP 0 640 539, a relatively common chute ^ moon trough is known from 201211266. Also counted. This patent proposes a chute body having a plurality of special holding chambers, which are only a branch and a shovel, and generally a trough-shaped, which is kept to a minimum of one layer of bulk. On the chute, to reduce the wear to: when the chute is not in the almost vertical (central loading) position, the effect of the deterioration is that the material hits the chute at a considerable angle. . In other words, 'typically, the distribution pattern of the charge is t, and most of the 曰4 of the 曰; the te-turn position exerts a considerable impact 胄, which adds the sliding friction to the damage of the The reason. In fact, in the case of a typical linear straight chute as proposed in European Patent No. EP 0 640 539, the angle of impact of the material on the β-smooth groove is equivalent to the inclination angle of the chute, for the outermost radial direction. The loading position, which may be much higher than 50. (From the vertical direction, in order to reduce the wear of the most wear-prone portion, i.e., the impact portion of the chute, it has thus been proposed to provide a chute body that is different from a typical straight shape. In the chutes, the impact portion is formed more than the outlet portion - a sharper angle to the vertical drop direction which determines the degree of radial flow deviation (loading radius, in other words, after the impact 2, the flow The direction is generally steeper than the direction of flow in the outlet. Therefore, such a chute almost achieves the same flow deviation while significantly reducing the impact load. Moreover, when striking at a sharper angle, the The flow is slowed down to a lesser extent. Thus, for another advantage, the material has a higher exit velocity at the outlet such that the chute can have a shorter chute length or a smaller angle chute. The inclination achieves the same charging radius, and the wear is further reduced by the latter option. 6 201211266 The boundary has a distribution chute body with a passage of a cream portion, the curved portion of the flow After impinging on the chute, it is rapidly diverted from a first flow direction to a second flow direction which is less steep in one of the outlets, such flow being, for example, from Japanese Patent Application No. JP 59-020412 and JP 59-03 1 807 It is known that the trough-shaped chute body JP59-020412 proposes a substantially flat downstream portion (Fig. 2: A_B) and an upstream portion that is curved into an arc shape (Fig. 2) 2: C_B), the arc has a center of curvature which is 〇5 to 4.0 times the length of the chute, more preferably 5 to 3 times the radius of the 。. Therefore, the flow of the filling material follows the chute The shape of the shock gradually changes its direction. However, the manufacture of such a curved shape is not economical, or it is likely to cause a rather fragile structure. Jp59_〇3i8〇7 proposes a very similar design. The trough-shaped chute body differs only in that the upstream portion is formed by a plurality of continuous straight segments, and is in tangential contact with the curved arc. The tuple has a length of the chute. , 〇 5 to 4.0 times the radius. Therefore, in (4).Q The zones proposed in 7 are similar to the curved shape in the aforementioned (iv) side 412, and are manufactured at the same time, which is likely to be more economical. Another type of chute body proposed in WO2009/037508 There is a downstream portion which is less steep than the upstream portion. The latter-described chute has a truncated-circular structure in a large body, and is particularly suitable for a so-called thorough charging device 1 Wherein, the chute pivots around the == universal joint of the two mutual J straight stomach. " is incompatible with the rotating and pivoting device, the chute is considered to be affected at the impact point Faster wear of 201211266. Although it has the obvious advantage of increasing service life due to reduced wear and possibly shorter chute length, it has a progressive material flow deviation from the distribution chute as discussed above, at least for metallurgical reactions It has not been widely adopted in the field of devices. In theory, the lack of such acceptance is particularly due to the difficulties associated with providing a structure for the chute body that is both economical and of sufficient strength to reliably resist application to the chute. The equivalent load, including the weight of the filling material and the dynamic load applied during the rotation and pivoting of the chute. [Summary of the Invention] Therefore, the purpose of this case is to provide a type of distribution chute with a strong and economical structure: the type of distribution chute has a boundary with - attached - The chute of the flow channel of the curved upstream portion: with a chute. For example, the high-aligning chute is included in the operation of the material with the bulk material, and the channel has a direction of turning to the invention. The invention proposes that the type of rotation and the type of pivoting can be used for a dispersion. The bismuth material is still in the bamboo knife distribution device, in particular, the one-step filling material distribution device using the furnace/mouth gold reactor. The sub-slot body (that is, the sub-knife is equipped with a load-supporting structure of the moon trough with an inlet and an outlet-flow, and ... the road] the inlet is used to connect the channel to the bulk::: The bulk material is used to send the = of the material to the outlet. The - the first part of the outlet - the first part of the flow - the f-fold of the flow maneuvering direction. According to this 8 201211266, the chute system has at least one An upstream portion and a downstream portion, the upstream portion including the inlet, and the downstream portion including the outlet, and being fixed to the upstream portion (ie, the upstream and downstream portions are secured against relative displacement). The downstream portion is defined There is a straight portion of the passage, and the upstream portion defines the inlet and the bend of the passage. Further, the upstream portion is thicker relative to the (thinner walled) downstream portion. It is understood that the main portion of the load applied to the distribution chute by the printed tamper material is received by the upstream portion of the thick wall of the body of the name (7). Due to the upstream of the chute The minute portion also includes the bent portion, and the majority of the steering force required to change the track of the bulk material in the transition region between the first and first first moving directions is also determined by the upstream portion Applied in the downstream portion of the trough 4, the material follows—a substantially linear track (in the reference system of the chute). Therefore, the wall strength of the downstream portion has been selected: The wall strength of the part is small. The result is a distribution chute, the rigidity of the mechanism, the structure based on the radially outward part, the ground force is on the chute bearing, and the system can be used for economic benefits. The overall tangential direction of the ancient mysterious (...the direction of the matching is equivalent to the high discharge angle at the bottom of the entrance, also the vertical central plane of the )), at least for the impact of the distribution chute, = about 45 ° The flow of material in the overall tangential direction of the bottom (in 兮, °, the flow direction is equivalent to the bottom of the outlet, the word "quote" is the vertical central plane of the monthly consumption. In the distribution chute The angle between the mouth and the vertical 201211266 direction. According to a preferred embodiment of the invention, the upstream portion is made of cast metal such as cast iron or cast steel. Those skilled in the art will appreciate that casting technology is based. The use of 'can obtain the ancient diversity of the shape of the upstream portion. In other words, compared to the design of the prior art, the design of the chute is less restrictive, which makes it easier to modify according to the application. The chute body, available space, and other parameters. Preferably, the downstream portion includes one or more welded steel plates that are welded. The inlet of the channel of the distribution chute is preferably provided as a An annular collar on the upstream portion. The inlet is thus formed as a tubular section (which encloses the axis of the inlet in a circumferential manner). The annular collar strengthens the upstream. The p-knife 4爻 Relative torque, without significant deformation. 3 According to a preferred embodiment of the 4 dispensing chute, the downstream portion includes a tubular section providing an outlet. As will be appreciated by those skilled in the relevant art, this reduces (or eliminates) the lateral overflow of the bulk material, which ultimately results in an improvement in the charge distribution under the chute (4). Most preferably, the downstream A portion of the junction from which the upstream portion is attached is tapered toward the outlet. Preferably, the passage has a first passage axis in the inlet (corresponding to the Sx taxi maneuvering direction) and a second passage axis in the outlet (corresponding to the =L moving direction), etc. There is a slight difference between the bends in the upstream portion. This angle is preferably tied to 15. To 45. The range is more than 20 to 4 更. The scope. The bend may be defined in the upstream portion as the bend may be steep (steep). A curved transition region between the inlet and the bottom of the passage 10 201211266. It should be able to appreciate the use of casting techniques in the manufacture of this upstream portion, which can easily be achieved on curved surfaces in three dimensions. To combine the upstream portion with the downstream portion, the upstream portion includes a coupling end facing the inlet (in the case of the bend). The downstream portion is preferably inserted into the attachment end, e.g., up to the bend, and is shackled and positioned using screws, bolts, rivets, welds, or any other suitable securing mechanism. The length of the overlap portion of the junction end portion and the downstream portion is preferably at least 20% of the total length of the downstream portion, for example, between 20% and 40%. According to a preferred embodiment of the present invention, the dispensing chute includes an insert in the upstream portion of the crucible and/or in the downstream portion, the insert comprising a plurality of holding chambers (stone boxes) The system is opened to the passage so as to be able to fill the bulk material used to protect the distribution chute from abrasion. Preferably, the inserts are at least about 30 in the form of a bulk material such as a bulk material. Any surface impinging on one of the angles is protected by a stone chamber. This approach ensures that the areas on the surface of the channel that are most susceptible to flow rot by the impact material are suitably protected. It should be appreciated that the (and the like) inserts may be individually replaced from the chute body after being worn. This helps keep maintenance costs low. It should be noted that in addition to the insert in the form of a retaining chamber, it is also possible to provide an insert in the form of a casting or a ceramic wear plate. Preferably, the outlet of the distribution chute is formed by a wear-resistant sliding insert member at the downstream portion. The slider has - substantially smoother in the exit than the area configured with each &: 201211266 face, in order to discharge the concentrated and uniform flow of bulk material as much as possible. The preferred groove of the groove body has an opening on the inner side of the bent portion. An advantage of such an opening is that, for example, the weight reduction of the chute does not compromise wear resistance, and when the chute is oriented substantially perpendicular to the center charge (ie, when the discharge angle is less than about 15) . . . , does not impair the removal of the "obstacle" into the bulk material. The distribution chute may include operational trunnions on the upstream portion, which is a chute can be - The tilting mechanism is cut on top of it. (4) The operating trunnion is preferably integrally formed with the upstream portion. The invention is preferably a related metallurgical reactor, for example: Attached is a charging device for a filling material dispensing device, the loading material dispensing device being provided with a dispensing chute as described herein. [Embodiment] ^With the following description, the following non-limiting types are preferred. Further details and advantages of the invention will be apparent from the following description. The same elements are used in the drawings to identify the same or similar components or elements. - distribution chute (four) roughly Shown in Figure 1. 兮8β ^ , δ " knife fit; the lure 10 includes a chute body 12, which is composed of: structural components: downstream of the bent iron plate on the cast steel The portion (4) and the distribution chute 1G may be formed together with the upstream portion 14_ body at two V.: The outer trunnion 18 is suspended to the - loading farm. The inlet 'one (circumferentially closed) tubular passage portion The end opposite the inlet of the upstream portion 12 201211266 is assembled such that the downstream component is secured to one of the coupling portions. The upstream and downstream portions 14, 16 are internal thereto. A passage 22 is defined. The passage 22 carries the bulk material entering the distribution chute 10 via the inlet 20 to the outlet 24' and the material is then discharged from the outlet 24, for example into a charging zone of a blast furnace. Figure 2 shows a configuration A blast furnace charge of the distribution chute is vibrated. The distribution chute 1 is pivotally suspended with its trunnion 18 to a rotatable structure 25. The rotatable structure 25 is by a large diameter The ball bearing W is rotatably supported by a fixed housing 30 The inner race of the ball bearing 32 is fixed to one of the top flanges 34 of the rotatable structure 25, and the outer race of the ball bearing 32 is fixed to one of the top plates 36 of the fixed housing 30. The balls: bearings 32 is assembled such that the rotatable structure 25 and the dispensing chute 1 are rotatable about the generally vertical axis 38, which axis is generally coincident with the central axis of the blast furnace. Positioned at the center of the axis 38+ and defining a passage for the bulk material to pass through the top plate 36. By rotating the dispensing chute 1 about the axis 38, and by varying the dispensing chute 10 about the pivot axis 39 The pivoting angle of the loading device of Figure 2 achieves the dispensing of the loading material in the loading zone of the blast furnace. The pivot axis 39 is generally perpendicular to the axis 38. Details of the mechanism suitable for rotating and pivoting the dispensing chute 10 are not shown in the drawings, and are not described herein for further reference. Those interested in these institutions, US3,880,302. The granules, etc.) pass through the bottom of the bulk material (e.g., coke, ore, feed port 20 is supplied to the distribution chute 1 at the bottom of 13 201211266. The impact position is based on Depending on the angle of inclination of the chute 1 。. In order to have a two-discharge angle (which is here between the velocity vector of the bulk material at the outlet 24 of the distribution/moon tank 10 and the vertical axis The angle 々), the bulk material impinges on the bottom of the channel adjacent the 20. By squashing the exit angle 'the impact position is removed from the inlet 2 朝向 toward the outlet 24 of the chute 10. The channel 22 has a bent portion 28' located in the upstream portion W for gradually deflecting material striking the bottom of the passage in the inlet 2 from a direction perpendicular to the discharge direction. Impacting the bottom of the passage in the inlet 20 The material is first diverted into a first flow direction generally parallel to the bottom of the inlet. At the bend 28 the material is then diverted into a second, parallel, parallel to the bottom of the outlet 24. Direction The portion 28 defines a bottom of the passage between the inlets: an angle α between the bottoms of the passages of the outlets in the range of 2 〇 to 4 。. The downstream portion 16 and the upstream portion 14 are fixed to each other The coupling portion 40 of the upstream portion 14 and the coupling portion 4 are disposed at opposite ends of the inlet 20 with respect to the bent portion 28. The upper portion of the downstream portion 6 is inserted into the coupling portion 40, The bent portion 28 is raised and fixed in the position. In the illustrated example, the length of the overlapping portion 4 and the overlapping portion of the migratory portion 16 amounts to about the entire length of the downstream portion 16 ^ One-third. As best illustrated in Figures 2 and 3, the dispensing chute includes a first insert 42 and a second insert 44, the first insert ο being defined upstream a plurality of holding chambers in the portion 14 and the second insert member 44 defines a plurality of holding chambers in the downstream portion 16. The holding chambers are opened to the passage by 14 201211266 to be able to fill the bulk material, and Therefore, the protection chute is protected against the wearer being placed at the most In the regions susceptible to erosion by the impacting material, each of the insert members 42, 44 includes a plurality of transverse plates 46 that tend to be generally opposite in direction to the bulk material 2. Or a plurality of longitudinal plates 48 are subdivided laterally of the passage: the holding chambers to ensure a more uniform filling of the holding chambers in the lateral regions of the chute 10. Various of the holding chambers Further details of a possible structure can be found, for example, in ΕΡ 0640539. The outlet 24 of the distribution chute 10 is formed by an anti-wear sliding insert 5〇 disposed in the downstream portion 16. Each of the plurality of holding chambers is disposed. The sliding insert 5 is formed with a substantially smooth and slightly tapered passage portion in the outlet so as to be capable of discharging - bulk material flow as concentrated and uniform as possible . From the sliding insertion: the formed surface is substantially aligned with the top edge of the transverse plates 46 and the downstream of the longitudinal plates of the bends 28. The slope of the outlet determines the discharge angle /3, which can be pivoted about the pivot axis 39 at about 1 〇 (central loading position) and about 5 。. Change between. The slewing groove body 12 has an opening 52 on the inner side of the bent portion 28. In the vertical cross-sectional view of FIG. 2, it is seen that the opening 52 is configured to have a recess that allows the angle of inclination of the chute 10 to be increased without contacting the bottom end of the rotatable structure 25. The radially inner edge of the flange. Another advantage of the sinus opening 5 2 is that, in the "central loading," position, the politic material can fall straight through the chute without being caused by the top of the passage 22. The deflection of the bend portion 28. In addition, the opening 15 201211266 may even serve as an overflow in some cases. In the illustrated distribution chute, the bend in the upstream member The fold is equivalent to a strip transition region between each substantially straight channel portion. Those skilled in the art will appreciate that the bend can also be implemented as a channel between the inlet and the outlet. A smoothly curved transition region between the bottoms.
