Abstract
Description
本發明大體而言係關於用於將燒結混合物(亦即,粉礦混合物及燃料)進料於帶式燒結機上以便形成燒結床之燒結機進料裝置。 The present invention generally relates to a sintering machine feed apparatus for feeding a sintered mixture (i.e., a fine ore mixture and a fuel) onto a belt sintering machine to form a sintered bed.
製作供鼓風爐中使用的粉礦團塊被稱為燒結或黏聚。燒結因此係使細粒鐵礦黏聚以用於鼓風爐爐料製備。在習知燒結廠中,將燒結混合物(亦即,粉礦混合物及燃料)置放於燒結皮帶(亦即,設計為格柵的輸送機皮帶)上。具有混合物之燒結皮帶(亦稱為燒結床)經過大量吸氣箱上方。經由此等吸氣箱抽吸空氣穿過燒結床。定位於第一吸氣箱上方的點火罩點燃燒結混合料。在經過其他吸氣箱上方期間,燃燒自頂部向下蔓延穿過燒結床。在燃燒期間,摻和的燃料產生溫度,該溫度剛好足以使粉礦在表面處軟化,以便粉礦混合物黏聚以形成燒結塊。在燒結期間產生之燃燒氣體與燃燒空氣一起經由吸氣箱排出。燒結廠通常係以吸氣箱經由靜電過濾器(在一些情況下亦為織物過濾器)連接至風扇的方式配備,該風扇在燒結皮帶下方產生所需的負壓力來抽吸所需的燃燒空氣穿過燒結床。隨後藉由風扇將清潔的氣體混合物經由煙囪排放至大氣中。 The production of fines ore agglomerates for use in blast furnaces is known as sintering or cohesion. Sintering thus causes the fine iron ore to be cohesive for use in blast furnace charge preparation. In conventional sinter plants, the sintered mixture (i.e., the fine ore mixture and fuel) is placed on a sintered belt (i.e., a conveyor belt designed as a grid). A sintered belt (also known as a sintered bed) with a mixture passes over a large number of suction boxes. The air is drawn through the sintering bed through the suction box. An ignition hood positioned above the first suction box ignites the sintered mixture. During the passage over the other suction boxes, the combustion spreads from the top down through the sintering bed. During combustion, the blended fuel produces a temperature just sufficient to soften the fines at the surface so that the fine ore mixture is cohesed to form agglomerates. The combustion gas generated during the sintering is discharged together with the combustion air through the suction box. The sinter plant is usually equipped with a suction box connected to the fan via an electrostatic filter (and in some cases also a fabric filter) which produces the required negative pressure under the sinter belt to pump the required combustion air. Pass through the sintering bed. The cleaned gas mixture is then vented to the atmosphere via a chimney by a fan.
鑒於經濟原因,鋼鐵工業力求不斷增加燒結廠之生產力。出於此目的,作為若干可能性之一,較佳的是增加給料至燒結皮帶上的層之 厚度。僅當混合物之滲透性得以改良且/或吸氣系統中之負壓力得以增加時,才可達成上述厚度增加而不降低生產力。 For economic reasons, the steel industry is striving to increase the productivity of the sinter plant. For this purpose, as one of several possibilities, it is preferred to increase the feed to the layer on the sintered belt. thickness. The above thickness increase can be achieved without reducing productivity only if the permeability of the mixture is improved and/or the negative pressure in the getter system is increased.
技術現況係給現有給料裝置配備分類裝置,該等分類裝置將大部分粗粒子自原始燒結混合物中分離出來且將該等粗粒子集中在給料層之下部區域中。 The current state of the art is to equip existing feed devices with sorting devices that separate most of the coarse particles from the original sintered mixture and concentrate the coarse particles in the lower region of the feed layer.
進一步已知的是,在給料裝置之情況下,以藉由給料操作達成混合材料分離的方式來設計滾筒斜槽(分離板)。然而,此設計不允許在良好分離的同時達成大的層厚度。 It is further known that, in the case of a feeding device, the drum chute (separation plate) is designed in such a way that a mixing of the materials is achieved by the feeding operation. However, this design does not allow for a large layer thickness to be achieved while good separation.
JP 2001-227872揭示經由具有兩個出料口之給料倉對燒結材料進行雙層給料。將燒結材料以分離發生於給料倉中的方式進料至給料倉中。出料口中之每一者配有包含給料裝置、給料滾筒及滾筒斜槽之完整系統。此變體之缺點為高維護成本,以及用於兩個給料滾筒之複雜的且容易發生故障的控制系統。 JP 2001-227872 discloses double layer feeding of a sintered material via a feed bin having two discharge ports. The sintered material is fed into the feed bin in such a manner that separation takes place in the feed bin. Each of the discharge ports is provided with a complete system comprising a feed device, a feed roller and a drum chute. Disadvantages of this variant are high maintenance costs, as well as complex and prone to faulty control systems for the two feed rolls.
US 2008/0108006 A1描述用於帶式燒結機之給料裝置,該給料裝置具有用於接收將被燒結之材料的給料容器、具有用於用將被燒結之材料裝填給料容器的輸送裝置、具有用於使將被燒結之材料給料至燒結皮帶上的給料滾筒及滾筒斜槽,其中給料容器具備用於將被燒結之材料的兩個出料口,並且第一出料口連接至給料滾筒且第二出料口連接至給料斜槽以使將被燒結之材料給料至燒結皮帶上,輸送裝置係以如下方式佈置以使其對將被燒結之材料具有衝擊點,該衝擊點位於給料容器之定位於第一出料口上方的半部中,且第二出料口佈置於由將被燒結之材料形成的斜坡區域中。 US 2008/0108006 A1 describes a dosing device for a belt sintering machine having a feed container for receiving material to be sintered, having a conveying device for filling the feed container with the material to be sintered, useful Feeding the material to be sintered to a feed drum and a drum chute on the sintering belt, wherein the feed container is provided with two discharge ports for the material to be sintered, and the first discharge port is connected to the feed roller and The two discharge ports are connected to the feed chute to feed the material to be sintered onto the sintering belt, and the conveying device is arranged in such a way as to have a point of impact on the material to be sintered, the impact point being located at the feeding container In the half above the first discharge opening, and the second discharge opening is arranged in a sloped region formed by the material to be sintered.
然而,此等系統相當複雜且因此建構及維護的費用高。 However, such systems are quite complex and therefore costly to construct and maintain.
因此,本發明之一目標係提供一種燒結機進料裝置,該燒結機進料裝置達成良好的分離且具有易於維護的提取裝置。 Accordingly, it is an object of the present invention to provide a sintering machine feed apparatus that achieves good separation and has an easy to maintain extraction apparatus.
此目標係由如申請專利範圍第1項中所主張的燒結機進料裝置達成。 This object is achieved by a sintering machine feed device as claimed in claim 1 of the scope of the patent application.
本發明之一般描述General description of the invention
本發明大體而言係關於用於將燒結混合物進料於帶式燒結機上以便形成燒結床的燒結機進料裝置,如申請專利範圍第1項之特徵定義前的部分中所闡述。 The present invention is generally directed to a sintering machine feed apparatus for feeding a sintering mixture onto a belt sintering machine to form a sintering bed, as set forth in the section prior to the definition of the features of claim 1 of the patent application.
為了克服以上提及之問題,本發明提出一種用於將燒結混合物進料於帶式燒結機上以便形成燒結床的燒結機進料裝置,該進料裝置包含用於接收將被燒結之材料的給料容器、用於用將被燒結之材料裝填給料容器的輸送裝置、用於使將被燒結之材料給料至燒結皮帶上的提取裝置,其中該給料容器具備用於將被燒結之材料的出料口。該提取裝置包含:複數個提取滾輪,其位於該出料口下方,用於自該給料容器提取將被燒結之材料,該等提取滾輪圍繞中心軸旋轉且各自具有直徑,該直徑覆蓋該出料孔之5%至50%;複數個分離滾輪,其用於分離所提取之將被燒結之材料且將該材料沈積至該燒結皮帶上,其中提取滾輪位於第一平面中且分離滾輪位於第二平面中。 In order to overcome the above mentioned problems, the present invention proposes a sintering machine feeding device for feeding a sintering mixture onto a belt sintering machine to form a sintering bed, the feeding device comprising a material for receiving a material to be sintered a feed container, a conveying device for loading a material to be sintered with a material to be sintered, an extracting device for feeding a material to be sintered onto a sintering belt, wherein the feeding container is provided with a material for discharging the material to be sintered mouth. The extraction device comprises: a plurality of extraction rollers located below the discharge opening for extracting material to be sintered from the feed container, the extraction rollers rotating about a central axis and each having a diameter covering the discharge 5% to 50% of the holes; a plurality of separation rollers for separating the extracted material to be sintered and depositing the material onto the sintered belt, wherein the extraction roller is in the first plane and the separation roller is in the second In the plane.
用於將燒結混合物進料於帶式燒結機上的上述燒結機進料 裝置相比所描述之先前技術裝置而言複雜性更低且更易於維護,且仍然達成將被進料於燒結皮帶上之材料的良好分離。 The above-mentioned sintering machine feed for feeding the sintering mixture to the belt sintering machine The device is less complex and easier to maintain than the prior art devices described, and still achieves good separation of the material to be fed onto the sintered belt.
與先前技術之第一顯著差異在於,在本發明中不使用給料器滾筒。提出使用一系列提取滾輪來代替給料器滾筒,該等提取滾輪圍繞其中心軸旋轉。 A first significant difference from the prior art is that the feeder roller is not used in the present invention. Instead of a feeder roller, a series of extraction rollers are proposed which rotate about their central axis.
提取滾輪及分離滾輪之軸垂直於燒結皮帶之前進方向。 The axes of the extraction rollers and the separation rollers are perpendicular to the forward direction of the sintering belt.
此等提取滾輪置放於在給料容器之出料口下方的平面中,且經由該等提取滾輪之旋轉,使將被燒結之材料經由可調出料閘自給料容器傳送出來。此等滾輪具有比傳統給料器滾筒小得多的直徑,因此兩個至二十個提取滾輪可置放於給料器容器之出料口下方。 The extraction rollers are placed in a plane below the discharge opening of the feed container, and the material to be sintered is conveyed from the feed container via the adjustable discharge gate via the rotation of the extraction rollers. These rollers have a much smaller diameter than conventional feeder rollers, so two to twenty extraction rollers can be placed below the discharge opening of the feeder container.
因為在滾輪中之每一者之間存在間隙,所以較細粒材料經由此等間隙掉落在燒結床之頂部上,而較粗材料在提取滾輪及分離滾輪之整個長度上得以傳送且沈積在燒結床之下部區域中。實際上,因為燒結皮帶在燒結機進料裝置下方前進,所以首先沈積粗材料以便形成燒結床之下部區域。因為當燒結床在滾輪下方前進時,燒結床已部分形成,所以在滾輪之間隙之間掉落的較細粒材料掉落在已進料於燒結床上的粗材料頂部上。因此可靠地達成材料之良好分離。 Because there is a gap between each of the rollers, the finer particulate material falls through the gaps on top of the sintering bed, while the coarser material is transported over the entire length of the extraction roller and the separation roller and deposited In the lower part of the sintering bed. In fact, since the sintered belt advances under the sintering machine feed device, the coarse material is first deposited to form the lower portion of the sintering bed. Because the sintered bed is partially formed as the sintered bed advances under the roller, the finer particulate material falling between the gaps of the rollers falls onto the top of the coarse material that has been fed to the sintering bed. A good separation of the material is thus reliably achieved.
提取滾輪各自具有直徑,該直徑較佳地覆蓋出料口之10%至45%,更佳地覆蓋出料口之15%至40%,最佳地覆蓋出料口之18%至35%。 The extraction rollers each have a diameter that preferably covers from 10% to 45% of the spout, more preferably from 15% to 40% of the spout, and optimally covers from 18% to 35% of the spout.
提取滾輪及/或分離滾輪可具有至少50mm之最小直徑。此等滾輪較佳地具有小於500mm之最大直徑。較佳地,提取滾輪及/或分離滾輪之直徑為至少100mm且小於350mm。 The extraction roller and/or the separation roller can have a minimum diameter of at least 50 mm. These rollers preferably have a maximum diameter of less than 500 mm. Preferably, the extraction roller and/or the separation roller have a diameter of at least 100 mm and less than 350 mm.
較佳地,所有提取滾輪具有相同直徑。較佳地,所有分離滾輪具有相同直徑。更佳地,所有滾輪具有相同直徑。 Preferably, all of the extraction rollers have the same diameter. Preferably, all of the separating rollers have the same diameter. More preferably, all of the rollers have the same diameter.
在一較佳實施例中,提取滾輪之直徑比分離滾輪之直徑大1.2倍與5倍之間。 In a preferred embodiment, the diameter of the extraction roller is between 1.2 and 5 times larger than the diameter of the separation roller.
出料口較佳地量測為800mm至2000mm。此意味著,在知道第一滾輪之軸大體上與給料容器之第一壁對準的情況下,可將滾輪之間具有約4mm之間隙的直徑約為80mm之11個滾輪置放在約800mm之出料口下方。 The discharge port is preferably measured to be 800 mm to 2000 mm. This means that, in the case where the shaft of the first roller is known to be substantially aligned with the first wall of the feed container, 11 rollers having a diameter of about 4 mm with a gap of about 4 mm between the rollers can be placed at about 800 mm. Below the discharge opening.
提取滾輪及分離滾輪之旋轉速度係單獨可調的,且較佳地小於100rpm但至少為5rpm,較佳地,提取滾輪及分離滾輪之旋轉速度小於80rpm但至少為10rpm,更佳地小於60rpm但至少為12rpm,且最佳地小於50rpm但至少為15rpm。提取滾輪及分離滾輪可由單個馬達驅動,或單獨的電動馬達可驅動每一滾輪。在後一種狀況下,滾輪之速度係單獨可調的。 The rotation speeds of the extraction roller and the separation roller are individually adjustable, and preferably less than 100 rpm but at least 5 rpm. Preferably, the extraction roller and the separation roller rotate at a speed of less than 80 rpm but at least 10 rpm, more preferably less than 60 rpm. At least 12 rpm, and optimally less than 50 rpm but at least 15 rpm. The extraction roller and the separation roller can be driven by a single motor, or a separate electric motor can drive each roller. In the latter case, the speed of the rollers is individually adjustable.
在一較佳實施例中,提取滾輪之旋轉速度低於分離滾輪之旋轉速度低。 In a preferred embodiment, the speed of rotation of the extraction roller is lower than the rotational speed of the separation roller.
若在給料容器之出料閘處的最後一個提取滾輪nx之旋轉速度為100%,則滾輪nx-1、nx-2等之旋轉速度遞減。在一較佳實施例中,n1(在出料閘對面的提取滾輪)之旋轉速度為nx之旋轉速度之約10%,較佳地約6%且最佳地約2%。一個滾輪nn+1與緊挨著該滾輪的滾輪nn之間的旋轉速度差異為比滾輪nn之旋轉速度高約5%、較佳地約8%且最佳地約10%。 If the rotational speed of the last extraction roller n x at the discharge gate of the feed container is 100%, the rotational speeds of the rollers n x-1 , n x-2 and the like are decreased. In a preferred embodiment, the rotational speed of n 1 (extraction roller opposite the discharge gate) is about 10%, preferably about 6% and most preferably about 2% of the rotational speed of n x . A roller n n + 1 next to the roller and the wheel rotational speed difference between n and n is greater than the rotational speed of the wheel n n of about 5%, preferably from about 8% and most preferably about 10%.
提取滾輪之平面較佳地與水平面形成介於0度與+45度之間 的角度。更佳地,提取滾輪與水平面之角度介於0度與20度之間。 The plane of the extraction roller preferably forms between 0 and +45 degrees with the horizontal plane Angle. More preferably, the angle of the extraction roller to the horizontal plane is between 0 and 20 degrees.
分離滾輪之平面較佳地與水平面形成介於0度與-70度之間的角度。更佳地,分離滾輪與水平面之角度介於0度與-40度之間。 The plane of the separating roller preferably forms an angle with the horizontal plane between 0 and -70 degrees. More preferably, the angle of the separation roller from the horizontal plane is between 0 and -40 degrees.
根據一較佳實施例,提取滾輪及分離滾輪在相同平面中,亦即,第一平面與第二平面相同。 According to a preferred embodiment, the extraction roller and the separation roller are in the same plane, i.e., the first plane is the same as the second plane.
較佳地,在滾輪中之每一者之間存在至少1mm之間隙。此間隙可對於所有提取滾輪為相同的且對於所有分離滾輪為相同的。在一較佳實施例中,提取滾輪之間的間隙可單獨調整。每一滾輪之間的間隙較佳地不大於10mm。更佳地,每一滾輪之間的間隙較佳介於2mm與8mm之間。 Preferably, there is a gap of at least 1 mm between each of the rollers. This gap can be the same for all extraction rollers and the same for all separation rollers. In a preferred embodiment, the gap between the extraction rollers can be individually adjusted. The gap between each roller is preferably no more than 10 mm. More preferably, the gap between each of the rollers is preferably between 2 mm and 8 mm.
本進料裝置之另一優點在於,可使用不同形式之給料器容器。實際上,在先前技術給料器滾筒的情況下,必須使用具有漏斗形下部分的給料器容器,而在本發明之狀況下,可使用直壁給料器容器。由於提取滾輪,將使給料器容器「集體」變空,此意味著給料器容器中之材料之上層將保持大體上水平:在使用提取滾輪使給料器容器變空期間,不會在材料中不形成漏斗。因此,可使用更大容量的給料器容器或可使裝置更緊湊。 Another advantage of the present feed device is that different types of feeder containers can be used. In fact, in the case of prior art feeder rolls, it is necessary to use a feeder container having a funnel-shaped lower portion, and in the case of the present invention, a straight wall feeder container can be used. By extracting the rollers, the feeder container will be "collectively" empty, which means that the upper layer of material in the feeder container will remain substantially horizontal: during the use of the extraction roller to empty the feeder container, it will not be in the material. Form a funnel. Therefore, a larger capacity feeder container can be used or the device can be made more compact.
因為可使用具有直壁之給料器容器,所以使將在給料器容器內部形成附積物之風險最小化。 Since a straight walled feeder container can be used, the risk of depositing deposits inside the feeder container is minimized.
如將理解,雖然不限於此,但所提出之設備尤其適合於鼓風爐廠以及非鐵金屬處理廠。 As will be understood, although not limited thereto, the proposed apparatus is particularly suitable for blast furnace plants as well as non-ferrous metal processing plants.

FIG. 5 illustrates a fourth embodiment of a sintering machine feeding device according to the present invention, the same reference numerals being used in all drawings to identify structural or functional Similar components.
在圖1處描繪燒結機進料裝置10之第一傳統設計。在給料斗12(儲倉、給料容器)下方安裝相對大的給料器滾筒14,該給料器滾筒圍繞其中心軸16旋轉且藉此自給料斗12提取材料。必須注意的是,在此類型之進料裝置10中,每個給料斗12使用僅一個給料器滾筒14,且該給料器滾筒14之直徑比給料斗12之出料口18大得多。所提取材料20掉落在分離板22上,該分離板位於給料器滾筒14下方且用來在所提取材料20降落在燒結皮帶(未示出)上之前使所提取材料之掉落發生偏轉。 A first conventional design of the sintering machine feed device 10 is depicted at FIG. A relatively large feeder drum 14 is mounted below the hopper 12 (storage bin, feed container) which rotates about its central axis 16 and thereby extracts material from the hopper 12. It has to be noted that in this type of feeding device 10, only one feeder drum 14 is used per hopper 12, and the diameter of the feeder drum 14 is much larger than the discharge port 18 of the hopper 12. The extracted material 20 is dropped onto a separator plate 22 which is positioned below the feeder drum 14 and serves to deflect the drop of the extracted material before the extracted material 20 landed on the sintering belt (not shown).
自JP 2005 226113 A得知類似的燒結機進料裝置。在給料斗12(儲倉、給料容器)下方安裝單個相對大的給料器滾筒,該給料器滾筒圍繞其中心軸旋轉且藉此自給料斗提取材料。所提取材料在如JP 2005 226113 A之圖1中所描繪的一個實施例中掉落在分離板上,該分離板位於 給料器滾筒下方且用來在所提取材料降落在燒結皮帶上之前使所提取材料之掉落發生偏轉。在如JP 2005 226113 A之圖2中所描繪的第二實施例中,所提取材料掉落在一系列分離滾輪上,該等分離滾輪位於給料器滾筒下方且用來在所提取材料降落在燒結皮帶上之前使所提取材料之掉落發生偏轉且根據所提取材料之大小對其進行分離。控制每一滾輪或滾輪群組之圓周速度,以使上游側上之速度高於下游側上之速度。 A similar sintering machine feed device is known from JP 2005 226113 A. A single relatively large feeder drum is mounted below the hopper 12 (storage, feed container), which rotates about its central axis and thereby extracts material from the hopper. The extracted material is dropped onto a separating plate in an embodiment as depicted in Figure 1 of JP 2005 226113 A, the separating plate being located Below the feeder drum and for deflecting the drop of the extracted material before the extracted material falls onto the sintered belt. In a second embodiment, as depicted in Figure 2 of JP 2005 226113 A, the extracted material falls onto a series of separating rollers that are positioned below the feeder drum and used to sinter on the extracted material. The drop of the extracted material is deflected prior to the belt and separated according to the size of the material being extracted. The peripheral speed of each roller or group of rollers is controlled such that the speed on the upstream side is higher than the speed on the downstream side.
此等傳統裝置具有若干缺點: These conventional devices have several disadvantages:
1.給料斗12之直徑在其整個高度上並非恆定的,而是在其下端處為漏斗形的。由於此漏斗形下端24,材料往往會在給料斗之漏斗形下端與垂直上部分26之間的邊界區域處黏附至給料斗12之壁,且在此處形成附積物28。此進一步減小給料斗12之出料口18之有用直徑,且材料之通過量隨時間變化。因此定期需要昂貴的維護工作以便自給料斗12消除附積物28。 1. The diameter of the hopper 12 is not constant over its entire height, but is funnel-shaped at its lower end. Due to this funnel-shaped lower end 24, the material tends to adhere to the wall of the hopper 12 at the boundary between the funnel-shaped lower end of the hopper and the vertical upper portion 26, and the deposit 28 is formed there. This further reduces the useful diameter of the discharge opening 18 of the hopper 12 and the throughput of the material changes over time. Therefore, expensive maintenance work is required periodically to eliminate the buildup 28 from the hopper 12.
2.自給料斗12提取之材料可能亦黏附至給料器滾筒14,因此在給料器滾筒14之全轉已發生之前,該給料器滾筒必須被刮除乾淨任何此類材料。對給料器滾筒14之此刮除將引起磨損,且最終必須更換或修理滾筒。 2. The material extracted from the hopper 12 may also adhere to the feeder drum 14, so the feeder drum must be scraped off any such material before the full rotation of the feeder drum 14 has occurred. This scraping of the feeder drum 14 will cause wear and eventually the drum must be replaced or repaired.
3.自給料斗12提取之材料在掉落於燒結皮帶上之前首先撞擊分離板22或分離滾輪。若給料含有糰粒,則糰粒可能在撞擊在分離板/滾輪上期間破碎且因此導致燒結床之較低品質。附積物(未示出)可能亦在分離板/滾輪上且尤其在撞擊點處形成,從而將最終需要停止進料來消除此等附積物。後果係昂貴的維護及/或效能損失。 3. The material extracted from the hopper 12 first strikes the separation plate 22 or the separation roller before falling onto the sintered belt. If the feed contains agglomerates, the agglomerates may break during impact on the separator/roller and thus result in a lower quality of the sintered bed. Attachment (not shown) may also be formed on the separation plate/roller and especially at the point of impact, so that it will eventually be necessary to stop the feed to eliminate such deposits. Consequences are costly maintenance and/or performance losses.
為說明本發明之第一實施例,圖2展示帶式燒結機10的圖解視圖,該帶式燒結機具有經設計來用於鼓風爐廠(鼓風爐廠未示出)之 燒結給料的給料裝置。如圖2中看出,用參考編號30描繪燒結皮帶機。在燒結皮帶32上方,存在用於將被燒結之材料的給料容器34及用於使將被燒結之材料給料至燒結皮帶32上的提取裝置,該給料容器包含出料口18。 To illustrate a first embodiment of the present invention, FIG. 2 shows a diagrammatic view of a belt sintering machine 10 having a design for use in a blast furnace plant (not shown in a blast furnace plant). A feed device for sintering feedstock. As seen in Figure 2, the sintered belt conveyor is depicted by reference numeral 30. Above the sintering belt 32, there is a feed container 34 for the material to be sintered and an extraction device for feeding the material to be sintered onto the sintering belt 32, which contains a discharge opening 18.
該提取裝置在此特定實施例中包含四個提取滾輪36,該等提取滾輪位於出料口18下方,用於自給料容器34提取該將被燒結之材料。此等提取滾輪36圍繞其中心軸16旋轉且因此經由可調出料閘38將材料自給料容器傳送出來。 The extraction device in this particular embodiment includes four extraction rollers 36 located below the discharge opening 18 for extracting the material to be sintered from the feed container 34. These extraction rollers 36 rotate about their central axis 16 and thus convey material from the feed container via the adjustable discharge gate 38.
在已離開可調出料閘38之後,將被燒結之材料由第二系列滾輪(五個分離滾輪40)接納且沈積在燒結皮帶32上以便形成燒結床44。 After having exited the adjustable discharge gate 38, the material to be sintered is received by a second series of rollers (five separation rollers 40) and deposited on the sintered belt 32 to form a sintered bed 44.
令人感興趣的是,已注意到材料並不撞擊任何分離板,但該材料平穩地沈積至燒結皮帶上。因此,給料中所含的糰粒將不會在撞擊時破碎,以便可達成燒結床之較佳品質。 Interestingly, it has been noted that the material does not strike any of the separator plates, but the material is deposited smoothly onto the sintered belt. Therefore, the agglomerates contained in the feedstock will not be broken upon impact so that a better quality of the sintered bed can be achieved.
裝置之另一顯著特徵在於,材料中之一些垂直地穿過提取滾輪36及分離滾輪40之間的間隙46。此細粒材料將因此掉落在已沈積於燒結皮帶32上的燒結床44頂部上,該燒結皮帶在給料容器34下方前進。穿過滾輪36、40之間的間隙46掉落在燒結床44上的材料之數量及粒度取決於滾輪36、40之間的間隙46之大小、滾輪36、40旋轉速度及滾輪36、40彼此之間的相對旋轉速度。 Another significant feature of the device is that some of the material passes vertically through the gap 46 between the extraction roller 36 and the separation roller 40. This fine particulate material will thus fall on top of the sintered bed 44 that has been deposited on the sintered belt 32, which is advanced under the feed container 34. The amount and size of material dropped through the gap 46 between the rollers 36, 40 on the sintering bed 44 depends on the size of the gap 46 between the rollers 36, 40, the rotational speed of the rollers 36, 40, and the rollers 36, 40. The relative rotational speed between.
裝置之另一特徵在於,滾輪36、40係自行清潔的。實際上,不需要安裝刮除器以自滾輪刮除掉任何附著材料,因為該等滾輪對自身進行清潔。實際上,形成於滾輪上的任何附積物將藉由相鄰滾輪之旋轉得以移除。 Another feature of the device is that the rollers 36, 40 are self-cleaning. In fact, there is no need to install a scraper to scrape off any adhering material from the rollers as they clean themselves. In fact, any deposits formed on the rollers will be removed by the rotation of adjacent rollers.
安裝在給料容器34下游的刮除器48使燒結床44平坦且刮除掉任何過剩材料以便獲得具有預定高度且具有水平表面的燒結床44。 A scraper 48 mounted downstream of the feed container 34 flattens the sintering bed 44 and scrapes off any excess material to obtain a sintered bed 44 having a predetermined height and having a horizontal surface.
圖3展示燒結機進料裝置10的另一實施例,其中使用七個提取滾輪36且將其編號為n1、n2、n3至nx。在此特定實施例中,提取滾輪36之旋轉速度不相同,但位於圖3之左手側的提取滾輪n1比緊挨著提取滾輪n1位於右側的滾輪n2轉動得慢。滾輪n2比滾輪n3旋轉得慢,等等,以使滾輪之旋轉速度自圖3之左手側(亦即,相對於燒結皮帶之下游側)至圖3之右手側(亦即,相對於燒結皮帶之上游側)增加。滾輪nn+1之速度滾輪nn之速度。此允許平穩地自給料容器排空將被燒結之材料。 3 shows another embodiment of a sintering machine feed device 10 in which seven extraction rollers 36 are used and numbered n 1 , n 2 , n 3 to n x . In this particular embodiment, the rotational speed of the extraction roller 36 is different, but the extraction roller n 1 on the left-hand side of Figure 3 rotates slower than the roller n 2 located immediately to the right of the extraction roller n 1 . The roller n 2 rotates slower than the roller n 3 , etc., so that the rotational speed of the roller is from the left hand side of FIG. 3 (ie, relative to the downstream side of the sintering belt) to the right hand side of FIG. 3 (ie, relative to The upstream side of the sintered belt is increased. Speed of the wheel n n+1 The speed of the wheel n n . This allows the material to be sintered to be emptied smoothly from the feed container.
在如圖3上所描繪之此特定實施例中,提取滾輪位於第一平面50中,而分離滾輪位於第二平面52中。提取滾輪36之第一平面50為水平的,而分離滾輪40之第二平面52相對於水平面成約-45°之角度。燒結機進料裝置10之此設計之特殊性在於以下事實:分離滾輪40所在的第二平面52之角度為可調的。由於分離滾輪之角度變化,可影響分離之品質。 In this particular embodiment as depicted on FIG. 3, the extraction roller is located in the first plane 50 and the separation roller is located in the second plane 52. The first plane 50 of the extraction roller 36 is horizontal, while the second plane 52 of the separation roller 40 is at an angle of about -45 to the horizontal. The particularity of this design of the sintering machine feed device 10 lies in the fact that the angle of the second plane 52 in which the separating roller 40 is located is adjustable. Due to the change in the angle of the separation roller, the quality of the separation can be affected.
圖3A更詳細地展示圖3之提取滾輪n1、n2及n3且尤其展示該等滾輪之間的間隙D1、D2及D3。間隙D1D2D3等。間隙之大小可自圖3之左側至右側(亦即,自第一提取滾輪至靠近出料閘之最後一個提取滾輪)增加的事實允許將較細粒材料沈積於燒結物之頂部上,該燒結物在給料容器下方自右手側至左手側行進。因此可獲得燒結床上良好品質的分離。 Figure 3A shows the extraction rollers n1, n2 and n3 of Figure 3 in more detail and in particular shows the gaps D1, D2 and D3 between the rollers. Clearance D1 D2 D3 and so on. The fact that the gap can be increased from the left to the right of Figure 3 (i.e., from the first extraction roller to the last extraction roller near the discharge gate) allows the deposition of finer particulate material on top of the sinter, which is sintered. The object travels from the right hand side to the left hand side below the feed container. A good quality separation of the sintered bed is thus obtained.
在圖4上所描繪之實施例中,第一平面50(亦即,提取滾輪36所在的平面)之角度及第二平面52(亦即,分離滾輪40所在的平面) 之角度均為可調的,且可獨立地改變。可因此實現材料自給料容器的更好提取。 In the embodiment depicted in Figure 4, the angle of the first plane 50 (i.e., the plane in which the extraction roller 36 is located) and the second plane 52 (i.e., the plane in which the separation roller 40 is located) The angles are all adjustable and can be changed independently. A better extraction of the material from the feed container can thus be achieved.
在圖5之實施例中,提取滾輪36之直徑大於分離滾輪40之直徑,而在其他各圖之實施例中,所有滾輪36、40之直徑為相同的。 In the embodiment of Figure 5, the diameter of the extraction roller 36 is greater than the diameter of the separation roller 40, while in the other embodiments of the figures, the diameters of all of the rollers 36, 40 are the same.
在圖6之實施例中,提取滾輪36之第一平面50及分離滾輪40之第二平面52均為水平的。 In the embodiment of Figure 6, the first plane 50 of the extraction roller 36 and the second plane 52 of the separation roller 40 are horizontal.
在所有圖2至圖6中,給料容器34具有直的垂直壁54,且並非如同使用滾筒給料器之傳統給料斗之情況一樣需要漏斗形下部分。在傳統給料斗中出現的附積物問因此得以避免,此係因為在本發明組態中,給料「集體」下降且給料容器34中的給料材料之上表面56保持水平。 In all of Figures 2 through 6, the feed container 34 has a straight vertical wall 54 and does not require a funnel-shaped lower portion as is the case with a conventional hopper using a roller feeder. The inclusions present in conventional hoppers are thus avoided because, in the configuration of the present invention, the feedstock "collectively" drops and the surface 56 of the feed material in the feed container 34 remains level.
總之,將瞭解,本發明不僅允許尤其用於鼓風爐及非鐵操作之燒結機進料裝置之操作效率的重要增加,而且容許較低資本及操作支出下的可靠操作。 In summary, it will be appreciated that the present invention not only allows for an important increase in the operational efficiency of the sinter furnace and non-iron operated sintering machine feed devices, but also allows for reliable operation at lower capital and operating expenses.
