Description
具有超强型耐热钢钢带的预热器旋风筒内筒 技术领域 Preheater cyclone inner cylinder with super heat-resistant steel strip
本发明涉及水泥生产设备，特别是一种具有超强型耐热钢钢带的预热器旋风筒内筒 及陶瓷挂片。 背景技术 The invention relates to a cement production equipment, in particular to a preheater cyclone inner cylinder and a ceramic hanging piece with a super-strong heat-resistant steel strip. Background technique
长期以来， 国内外干法水泥生产线中所应用的预热器旋风筒内筒， 材质以镍铬耐热 合金钢为主， 其突出缺点存在于两个方面： 一是钢材的价格比较昂贵， 每吨通常都在十 万元以上， 这样生产一个预热器旋风筒内筒造价将达到几十万元； 二是实用寿命较短， 合金钢的耐酸碱腐蚀性能较差， 在正常的状态下寿命平均只有 10— 14个月。 基于此造 成的停工检修更换内筒， 严重影响了企业的生产时间， 给企业生产成本造成了负担。 如 何制造一种具有高强度， 耐腐蚀耐磨损性能的内筒以替代现有的合金钢， 同时控制生产 成本， 提高实用寿命， 是水泥生产行业关注的技术问题。 For a long time, the inner cylinder of the preheater cyclone used in the dry cement production line at home and abroad is mainly made of nickel-chromium heat-resistant alloy steel. Its outstanding shortcomings exist in two aspects: First, the price of steel is relatively expensive. The ton is usually more than 100,000 yuan, so that the cost of producing a preheater cyclone cylinder will reach several hundred thousand yuan; the second is a short practical life, and the acid and alkali corrosion resistance of alloy steel is poor, under normal conditions. The average life expectancy is only 10-14 months. The replacement of the inner cylinder due to the shutdown and maintenance caused by this has seriously affected the production time of the enterprise and caused a burden on the production cost of the enterprise. How to manufacture an inner cylinder with high strength, corrosion resistance and wear resistance instead of the existing alloy steel, while controlling the production cost and improving the practical life is a technical problem of concern in the cement production industry.
现有技术已有采用成本低廉、 耐腐蚀、 耐磨损性能更好的陶瓷组件来制作预热器旋 风筒内筒， 如中国专利 200820188205.7记载了一种 "全陶瓷预热器内筒"， 其耐磨陶瓷 组件包括拼接组装的耐磨陶瓷柱和弧形陶瓷连接板， 耐磨陶瓷柱相互拼接， 拼接侧通过 字母对接口拼接， 耐磨陶瓷柱上下端与连接板分别设有连接口， 通过螺栓和螺母连接。 这种拼接方式结构简单， 拼接方便， 但是由于内筒仅有一层陶瓷柱， 陶瓷柱长度过长， 耐高温陶瓷加工难度大， 造成成本较高， 同时， 由于在温差下的热胀冷縮， 内外弧形连 接板与陶瓷柱在产生变形后出现松动， 无法紧密连接， 使用寿命不长。 中国发明专利 200810050022.3 "一种预热器旋风筒内筒用的陶瓷挂板与连接方法" 中公开了一种用尺 寸小的陶瓷挂板进行拼接， 小陶瓷挂板的加工难度减小， 但是这种陶瓷挂板结构复杂， 且拼接复杂， 同时还存在由于热胀冷縮造成陶瓷崩裂的危险。 发明内容 In the prior art, a ceramic assembly having a low cost, corrosion resistance and wear resistance is used to manufacture a preheater cyclone inner cylinder. For example, Chinese Patent No. 200820188205.7 describes an "all ceramic preheater inner cylinder", which The wear-resistant ceramic component comprises a wear-resistant ceramic column and a curved ceramic connecting plate which are spliced and assembled, the wear-resistant ceramic columns are spliced to each other, and the splicing side is spliced through the letter-pair interface, and the upper and lower ends of the wear-resistant ceramic column and the connecting plate respectively have a connection port, through Bolts and nuts are connected. The splicing method has a simple structure and convenient splicing. However, since the inner cylinder has only one ceramic column, the length of the ceramic column is too long, and the high temperature resistant ceramic processing is difficult, resulting in high cost, and at the same time, due to thermal expansion and contraction under temperature difference, The inner and outer curved connecting plates and the ceramic columns are loose after being deformed, and cannot be tightly connected, and the service life is not long. Chinese invention patent 200810050022.3 "a ceramic hanging plate and connection method for a preheater cyclone inner cylinder" discloses a splicing with a small ceramic hanging plate, and the processing difficulty of the small ceramic hanging plate is reduced, but this The ceramic hanging plate has a complicated structure and complicated splicing, and there is also a risk of ceramic cracking due to thermal expansion and contraction. Summary of the invention

高了内筒的使用寿命。 本发明还提供该旋风筒内筒的专用部件陶瓷挂片。 The object of the present invention is to solve the problem that the assembly of the existing preheater cyclone heat-resistant steel inner cylinder is difficult or complicated to process when the ceramic component is assembled, and the thermal expansion and contraction causes the ceramic to break and the heat resistance is not high enough. A problem that affects the quality and service life, and provides a preheater cyclone inner cylinder which is small in processing difficulty, simple in structure, and capable of preventing loose joints and short service life due to thermal expansion and contraction, and has low cost and acid resistance.

由于通过规则形状的板块结构在周向紧密排列形成筒状体， 及通过所述陶瓷挂片 前、后表面的上端部和下端部分别设置有贯通前后表面的通孔与陶瓷连接板相连， 不但 陶瓷挂片制作方便， 而且连接安装也很方便简单， 同时由于所述陶瓷挂片为中空腔体， 不但增强了绝热性能， 具有很好的吸收热胀冷縮的伸展收縮余地， 因此能保证陶瓷不因 为热胀冷縮出现断裂。 同时本实用新型的陶瓷挂片也具有陶瓷耐酸碱腐蚀性的优点， 因
此大大延长了筒体使用寿命。 本发明的陶瓷挂片在中空腔体中增设了超强型耐热钢钢 带， 相当于在组装起来的耐热旋风筒的内壁中间增设了一整层加强劲和耐热层， 使整个 设备耐热性能大大提高。超强型耐热钢钢带为耐热材料制备而成的片状结构， 其形状只 要满足在长度方向上有与上下各层陶瓷挂片的中空腔体高度之和一致， 宽度小于中空腔 体宽度， 且长度方向的设置有用于螺栓安装的对应于陶瓷挂片的通孔的安装孔即可。 超 强型耐热钢钢带的形状因此还可以有更多种变形， 都在本实用新型要求的保护范围内。 组装预热旋风筒时， 将超强型耐热钢钢带放入陶瓷挂片中， 其安装孔与陶瓷挂片的通孔 重叠， 螺栓从重叠孔中穿过进行紧固。 增设的超强型耐热钢钢带不仅仅增强了旋风筒内 筒的耐热性能， 延迟了使用寿命， 更增加了使用安全性， 在极端情况下--旋风筒内筒万 一发生断裂的情况下， 超强型耐热钢钢带将起到维持旋风筒连接结构， 使其不会瞬间散 架坍塌造成安全威胁， 犹如建筑物中增设的钢筋的功能， 起加强筋的作用。 本实用新型 由于采用了在其两个侧面分别设置有反向对称的嵌合台阶的陶瓷挂片，使得陶瓷挂片在 内筒上能够规整、 紧密的排列， 使内筒强度更高， 能承受更大的应力， 与镍铬耐热合金 钢制成的内筒体相比， 不但价格低， 而且耐高温， 耐腐蚀， 耐氧化， 耐磨损性能优良， 材质比重不到合金的 1/2， 使用寿命可达 3— 4年， 与镍铬合金内筒相比， 提高使用寿命 2— 3倍， 成本降低 70 %以上。 Since the tubular body is closely arranged in the circumferential direction by the regular-shaped plate structure, and the through-holes penetrating the front and rear surfaces are respectively connected to the ceramic connecting plates through the upper end portion and the lower end portion of the front and rear surfaces of the ceramic hanging piece, The ceramic coupons are easy to manufacture, and the connection and installation are also very convenient and simple. At the same time, since the ceramic coupons are hollow cavities, not only the thermal insulation performance is enhanced, but also the expansion and contraction space for absorbing thermal expansion and contraction is good, so that the ceramics can be ensured. No breakage occurs due to thermal expansion and contraction. At the same time, the ceramic hanging piece of the utility model also has the advantages of ceramic acid and alkali corrosion resistance, This greatly extends the life of the cylinder. The ceramic hanging piece of the invention adds a super-strong heat-resistant steel strip in the hollow cavity, which is equivalent to adding a whole layer of strong and heat-resistant layer in the middle of the assembled heat-resistant cyclone cylinder, so that the whole device The heat resistance is greatly improved. The super-strong heat-resistant steel strip is a sheet-like structure prepared from a heat-resistant material, and its shape is equal to the sum of the heights of the hollow cavities in the longitudinal direction and the ceramic coupons of the upper and lower layers, and the width is smaller than the hollow body. The width, and the length direction, may be provided with a mounting hole for the bolt mounting corresponding to the through hole of the ceramic tab. The shape of the super heat-resistant steel strip can therefore be more varied, and is within the scope of protection claimed in the present invention. When assembling the preheating cyclone, the super heat-resistant steel strip is placed in the ceramic coupon, the mounting hole overlaps with the through hole of the ceramic coupon, and the bolt passes through the overlapping hole for fastening. The addition of super-strong heat-resistant steel strip not only enhances the heat resistance of the inner cylinder of the cyclone, delays the service life, and increases the safety of use. In extreme cases, the inner cylinder of the cyclone tube breaks. In this case, the super-strong heat-resistant steel strip will maintain the connection structure of the cyclone, so that it will not fall apart and pose a safety threat. It is like the function of the added steel bars in the building and acts as a reinforcing rib. The utility model adopts a ceramic hanging piece which is provided with oppositely symmetrical fitting steps on both sides thereof, so that the ceramic hanging piece can be arranged regularly and tightly on the inner tube, so that the inner tube has higher strength and can withstand Larger stress, compared with the inner cylinder made of nickel-chromium heat-resistant alloy steel, not only low price, but also high temperature resistance, corrosion resistance, oxidation resistance, excellent wear resistance, and the material specific gravity is less than 1/2 of the alloy. The service life can reach 3-4 years. Compared with the nickel-chromium alloy inner cylinder, the service life is increased by 2-3 times and the cost is reduced by more than 70%.
纵向空腔的陶瓷挂片便于加工。所述纵向空腔为两个， 两个纵向空腔之间设置有纵 肋， 能对中空陶瓷挂片的支撑表面起到较好的支撑作用， 使陶瓷挂片既轻巧， 又结实。 The ceramic coupons of the longitudinal cavity are easy to process. The longitudinal cavity is two, and longitudinal ribs are arranged between the two longitudinal cavities, which can better support the supporting surface of the hollow ceramic hanging piece, so that the ceramic hanging piece is both light and strong.
设置中间连接板能方便地将上下陶瓷挂片连接为一体， 使所述筒状体为层状结构， 同时陶瓷挂片可以做得较小， 以易于成型。 将多个陶瓷挂片沿内筒轴向进行连接， 相对 于上下一体的陶瓷柱， 陶瓷挂片的加工难度和加工成本均可大幅下降； 另一方面， 采用 较小尺寸的陶瓷挂片， 可以根据工程需要将其应用于不同高度的内筒， 避免了因内筒高 度不同而要定制上下一体陶瓷柱的麻烦。 上下陶瓷挂片通过陶瓷连接板固定连接并形 成， 使上下陶瓷挂片的连接紧密， 也相应可以减小陶瓷挂片的长度， 便于陶瓷挂片的生 产。 The intermediate connecting plate can conveniently connect the upper and lower ceramic hanging pieces into one body, so that the cylindrical body has a layered structure, and the ceramic hanging piece can be made smaller to be easily formed. A plurality of ceramic coupons are connected along the axial direction of the inner cylinder, and the processing difficulty and the processing cost of the ceramic coupons can be greatly reduced with respect to the ceramic pillars integrated upward and downward; on the other hand, the ceramic coupons of smaller sizes can be used. According to the needs of the project, it can be applied to the inner cylinder of different heights, which avoids the trouble of customizing the upper and lower integrated ceramic columns due to the different height of the inner cylinder. The upper and lower ceramic coupons are fixedly connected and formed by the ceramic connecting plates, so that the connection of the upper and lower ceramic coupons is tight, and the length of the ceramic coupons can be reduced correspondingly, thereby facilitating the production of the ceramic coupons.
所述筒状体下部的每个陶瓷挂片的下部横向设置有两个通孔，便于与所述陶瓷连接 板相连， 这种方式是下不陶瓷挂片连接方便、 紧密。 The lower portion of each of the ceramic hanging pieces of the lower portion of the cylindrical body is laterally provided with two through holes for connection with the ceramic connecting plate, which is convenient and compact for the connection of the lower ceramic hanging sheets.

强型耐热钢具有较强的强度和韧性。 两种螺栓同时使用， 进一步保证了本发明的预热旋 风筒的使用安全性。 将所有的陶瓷挂片上每个纵向空腔一端上的通孔都设置为两个， 对应的超强型耐热钢钢带上的安装孔也都设为横向并列的两个，也都在本发明保护的范 围内。 Preferably, at least the upper end of each longitudinal cavity of the uppermost ceramic coupon connected to the fixing base has two laterally parallel through holes, and the mounting holes on the corresponding super heat-resistant steel strip are also laterally disposed. The two. One through hole is fastened with ceramic bolts, and the other through hole is fastened with bolts of super heat-resistant steel material, which can enhance the safety and service life of the installation. Ceramic bolts have anti-oxidation effects, but ductility and stress resistance are poor. Strong heat resistant steel has strong strength and toughness. The simultaneous use of the two bolts further ensures the safety of use of the preheating cyclone of the present invention. The through holes on one end of each longitudinal cavity of all the ceramic coupons are set to two, and the mounting holes on the corresponding super heat-resistant steel strips are also set to be laterally juxtaposed, both also in this Within the scope of the invention.
