The strip with a width greater than 600mm is called a wide strip, and the strip with a width of less than 600mm is called a narrow strip. The thickness of the strip can be as thin as 0.001mm. The stainless steel strip needs to be acidified first and then dried during the production and processing process. In the drying process of the existing technology, hot air drying is mostly used. This method causes the two sides of the strip to be less Insufficient heating, there is a problem of uneven drying.
同时，由于在酸化工序结束后，不锈钢带材表面附着有酸性溶液和金属颗粒，尽管在烘干前不锈钢带材表面会经过清理，但不锈钢带材表面仍会残留酸性溶液和金属颗粒进入烘干步骤，而酸性溶液在烘干时会产生酸性雾气腐蚀烘干设备内的零件，金属颗粒则会堆积在烘干设备的机械零件中，大大增加机械故障的概率。At the same time, since the acid solution and metal particles are attached to the surface of the stainless steel strip after the acidizing process, although the surface of the stainless steel strip will be cleaned before drying, the acid solution and metal particles will still remain on the surface of the stainless steel strip and enter the drying process. Steps, while the acid solution will produce acid mist to corrode the parts in the drying equipment during drying, and metal particles will accumulate in the mechanical parts of the drying equipment, greatly increasing the probability of mechanical failure.

当不锈钢带材9结束酸化工序后，通过两个传送辊组3将不锈钢带材9从左往右传输，并且经过烘干室2，与此同时，通过驱动件501将位于支撑板502上的热风机4升降至合适的高度，此时热风机4与不锈钢带材9表面的距离为五十至八十厘米之间，然后启动热风机4，通过热风机4吹出热风，对不锈钢带材9表面进行烘干，并且在烘干时，通过两个顶起器401支撑起不锈钢带材9，并且对不锈钢带材9产生挤压，使得不锈钢带材9被挤压成拱形，使不锈钢带材9拱起，进而使得不锈钢带材9表面的酸性水渍自动向不锈钢带材9两侧聚集，加快烘干速率，当热风机4对不锈钢带材9表面进行烘干时，为了防止热风机4吹出的气流发生大范围的扩散，致使气流运动至不锈钢带材9表面的两侧时，气流的流速大大降低，而且气流紊乱，无法达到烘干的效果，而且此时，大量的酸性水渍和金属颗粒聚集在不锈钢带材9表面的两侧，因此，需要对热风机4吹出的气流的进行限流，并且保证气流对不锈钢带材9表面两侧的烘干效果，因此，当不锈钢带材9从左向右传输时，不锈钢带材9经过四个引风器7内部，与此同时，热风机4吹出的气流在挡风板8的引导下，大量进入引风器7内部，进而通过相邻的两个引风器7形成一个腔室，大量气流进入腔室内，并且对经过腔室内的不锈钢带材9进行充分的烘干，通过腔室，可以有效防止气流的紊乱，造成大量酸性气体和金属颗粒在烘干室2内四处扩散，对烘干室2造成极大的损害，同时进一步提高了气流对不锈钢带材9的烘干效果，与此同时，为了进一步确保腔室的密封性，防止气流扩散，因此，当不锈钢带材9穿过相邻两个引风器7之间时，不锈钢带材9先与密封块601接触，由于密封块601呈四分之一圆弧状，当不锈钢带材9从左往右传输时，密封块601与不锈钢带材9接触，并且不锈钢带材9挤压密封块601，使得密封块601发生形变，确保密封块601和不锈钢带材9贴合紧密，防止烘干过程中气流从不锈钢带材9与引风器7之间的缝隙排出，导致烘干效果变差。After the stainless steel strip 9 finishes the acidification process, the stainless steel strip 9 is transported from left to right by two conveying roller sets 3, and passes through the drying chamber 2. Hot air blower 4 lifts to suitable height, and now the distance between hot air blower 4 and the surface of stainless steel strip 9 is between fifty to eighty centimeters, then start hot air blower 4, blow hot blast by hot air blower 4, to stainless steel strip 9 The surface is dried, and when drying, the stainless steel strip 9 is supported by two jacks 401, and the stainless steel strip 9 is squeezed, so that the stainless steel strip 9 is extruded into an arched shape, so that the stainless steel strip The material 9 is arched, and then the acidic water stains on the surface of the stainless steel strip 9 are automatically gathered to both sides of the stainless steel strip 9 to speed up the drying rate. When the hot air blower 4 is drying the surface of the stainless steel strip 9, in order to prevent the hot air 4 The blown airflow diffuses in a large range, causing the airflow to move to both sides of the surface of the stainless steel strip 9, the flow velocity of the airflow is greatly reduced, and the airflow is disordered, so that the drying effect cannot be achieved, and at this time, a large amount of acidic water stains and metal particles are gathered on both sides of the surface of the stainless steel strip 9, therefore, it is necessary to limit the flow of the airflow blown by the hot air blower 4, and ensure the drying effect of the airflow on both sides of the surface of the stainless steel strip 9, therefore, when the stainless steel strip When the material 9 is transported from left to right, the stainless steel strip 9 passes through the inside of the four air inducers 7. At the same time, the airflow blown by the hot air blower 4 enters the inside of the air inducer 7 in large quantities under the guidance of the wind deflector 8, and then A chamber is formed by two adjacent air inducers 7, and a large amount of air flows into the chamber, and the stainless steel strip 9 passing through the chamber is fully dried. Through the chamber, the turbulence of the air flow can be effectively prevented, causing a large number of Acid gas and metal particles spread around in the drying chamber 2, causing great damage to the drying chamber 2, and further improving the drying effect of the airflow on the stainless steel strip 9. At the same time, in order to further ensure the safety of the chamber Sealing, preventing airflow from diffusing. Therefore, when the stainless steel strip 9 passes between two adjacent air inducers 7, the stainless steel strip 9 first contacts the sealing block 601, because the sealing block 601 is in a quarter arc shape, when the stainless steel strip 9 is transported from left to right, the sealing block 601 is in contact with the stainless steel strip 9, and the stainless steel strip 9 squeezes the sealing block 601, so that the sealing block 601 is deformed, ensuring that the sealing block 601 and the stainless steel strip 9 fit tightly to prevent the airflow from being discharged from the gap between the stainless steel strip 9 and the air inducer 7 during the drying process, resulting in poor drying effect.
进一步，气流在运动至不锈钢带材9两侧时，存在气流减小的问题，且不锈钢带材9两侧为酸性水渍和金属颗粒的聚集部位，因此，气流减小降低了对不锈钢带材9两侧的烘干效果，因此，将引风器7设置为倒八字形，当气流进入引风器7时，流速不断增大，进而增强对不锈钢带材9表面两侧的烘干效果，随后气流通过连接器6流入固定仓5内，而固定仓5呈八字形，气流通过固定仓5时流速减小，进而使混合在气流中的金属颗粒沉降在固定仓5内，同时携带酸性雾气的气流通过进风管101进入冷凝器102，通过冷凝器102将气流中的酸性雾气冷凝成液体后排出，实现气固分离，节省后续的分离工序，降低生产成本。Further, when the airflow moves to both sides of the stainless steel strip 9, there is a problem that the airflow decreases, and the two sides of the stainless steel strip 9 are the gathering parts of acidic water stains and metal particles, so the reduction of the airflow reduces the impact on the stainless steel strip. 9, the drying effect on both sides, therefore, the air inducer 7 is set as an inverted figure-eight, when the air flow enters the air inducer 7, the flow rate increases continuously, thereby enhancing the drying effect on both sides of the surface of the stainless steel strip 9, Then the air flow flows into the fixed bin 5 through the connector 6, and the fixed bin 5 is in a figure-eight shape. When the air flow passes through the fixed bin 5, the flow velocity decreases, so that the metal particles mixed in the air flow settle in the fixed bin 5, and at the same time carry acid mist The air flow enters the condenser 102 through the air inlet pipe 101, and the acid mist in the air flow is condensed into a liquid by the condenser 102, and then discharged, realizing gas-solid separation, saving subsequent separation processes, and reducing production costs.

还包括有清理块203；两个第一滤网202上各固接有若干个清理块203；第一滤网202和第二滤网204被气流吹动后产生震动，同时第一滤网202上的清理块203和第二滤网204接触，并且剐蹭第二滤网204上的金属颗粒，使第二滤网204上的金属颗粒掉落，防止第二滤网204发生堵塞。Also includes a cleaning block 203; each of the two first filter screens 202 is fixedly connected with several cleaning blocks 203; the first filter screen 202 and the second filter screen 204 vibrate after being blown by the air flow, and the first filter screen 202 The cleaning block 203 on the top is in contact with the second filter screen 204, and scratches the metal particles on the second filter screen 204, so that the metal particles on the second filter screen 204 fall off, preventing the second filter screen 204 from clogging.
在气流通过进风管101进入冷凝器102之前，由于气流内混有金属颗粒，为了防止金属颗粒堵塞冷凝器102，同时影响后续的废气和金属颗粒的分离清理，当气流进入固定仓5时，由于固定仓5呈八字形，使气流通过固定仓5时流速减小，部分金属颗粒沉降在固定仓5内，另一部分金属颗粒混合在气流中首先被第一滤网202拦截，穿过第一滤网202的金属颗粒再次被第二滤网204拦截，实现双层过滤，并且第一滤网202和第二滤网204呈波浪状，增大第一滤网202和第二滤网204与金属颗粒的接触面积，提高对金属颗粒的过滤效果，同时，由于第一滤网202的网孔孔径大于第二滤网204，故而更多的金属颗粒穿过第一滤网202附着在第二滤网204上，进一步地，为了防止第二滤网204上附着的金属颗粒过多导致第二滤网204网孔堵塞，致使酸性雾气无法进入冷凝器102，故而在第一滤网202上设置有若干个清理块203，当气流与清理块203接触时，且由于第一滤网202呈波浪形，且第一滤网202具有形变能力，通过气流使得第一滤网202发生形变，并且由于气流流向的原因，使得第一滤网202向靠近第二滤网204方向发生形变，进而使得清理块203向靠近第二滤网204移动，并且与第二滤网204接触，在清理块203与第二滤网204接触时，由于气流无法保持恒定，因此，清理块203和第二滤网204均处于不断摆动的状态，且摆动的幅度存在一定的差异，因为气流在经过第一滤网202之后，流速减小，使得第二滤网204的摆动幅度减小，清理块203和第二滤网204之间发生相对摆动，进而通过清理块203对第二滤网204进行剐蹭，将第二滤网204上的金属颗粒刮落，使其沉降在固定仓5内，进而有效防止第二滤网204发生堵塞，影响对金属颗粒的持续过滤。Before the airflow enters the condenser 102 through the air inlet pipe 101, since the airflow is mixed with metal particles, in order to prevent the metal particles from clogging the condenser 102 and affect the subsequent separation and cleaning of exhaust gas and metal particles, when the airflow enters the fixed bin 5, Since the fixed bin 5 is in a figure-eight shape, the flow velocity of the airflow decreases when passing through the fixed bin 5, and part of the metal particles settle in the fixed bin 5, while the other part of the metal particles mixed in the airflow are first intercepted by the first filter screen 202 and pass through the first filter screen 202. The metal particles of the filter screen 202 are intercepted by the second filter screen 204 again, realizing double-layer filtration, and the first filter screen 202 and the second filter screen 204 are wavy, increasing the first filter screen 202 and the second filter screen 204 and The contact area of the metal particles improves the filtering effect of the metal particles. At the same time, because the mesh aperture of the first filter screen 202 is larger than the second filter screen 204, more metal particles pass through the first filter screen 202 and adhere to the second filter screen 202. On the filter screen 204, further, in order to prevent the second filter screen 204 from clogging the meshes of the second filter screen 204 caused by too many metal particles attached to the second filter screen 204, so that the acid mist cannot enter the condenser 102, so it is installed on the first filter screen 202 There are several cleaning blocks 203, when the air flow contacts the cleaning block 203, and because the first filter screen 202 is wavy, and the first filter screen 202 has deformability, the first filter screen 202 is deformed by the air flow, and due to Due to the direction of the airflow, the first filter screen 202 is deformed towards the direction close to the second filter screen 204, and then the cleaning block 203 is moved close to the second filter screen 204, and contacts with the second filter screen 204. When the second filter screen 204 is in contact, because the airflow cannot be kept constant, the cleaning block 203 and the second filter screen 204 are in a state of constant swing, and there is a certain difference in the amplitude of the swing, because the airflow passes through the first filter screen 202 Afterwards, the flow velocity decreases, so that the swing amplitude of the second filter screen 204 decreases, and relative swing occurs between the cleaning block 203 and the second filter screen 204, and then the second filter screen 204 is scratched by the cleaning block 203, and the second filter screen 204 is scraped. The metal particles on the filter screen 204 are scraped off, causing them to settle in the fixed chamber 5, thereby effectively preventing the second filter screen 204 from clogging and affecting continuous filtering of the metal particles.
