SZR系列熱礦振動篩(熱礦篩)工作原理和結構特點

    SZR系列熱礦振動篩為座式安裝,采用雙軸振動器振動。雙軸振動器兩根軸由兩臺電動機分別帶動做反向自同步旋轉,使篩箱產生直線振動。電動機安裝在篩箱側面的固定支架上,故電動機不參振。電動機和雙軸振動器之間,兩臺雙軸振動器之間均采用萬向聯軸器連接,萬向聯軸器同時具有角度和長度的補償作用,可以滿足篩機工作時電動機和振動器之間的相對位移要求。
    根據電動機和振動器安裝位置的不同,熱礦振動篩可制定成上振式或下振式。SZR系列熱礦振動篩均配備二次隔振系統,對基礎的動負荷較小,使用于有隔振減振要求,安裝高度允許的場合。
    熱礦篩篩箱的側板與橫梁采用優質耐熱不銹鋼(或優質耐熱鋼)制造,主受力板和側板的連接,側板和橫梁的連接采用環槽鉚釘鉚接,連接緊固可靠。
   熱礦振動篩工作時,篩板直接與高溫物料接觸,要求有較好的耐磨、耐熱性能,故采用耐熱合金鑄鋼。工作時篩板會受熱膨脹,篩板固定裝置采用斜插緊固,并設有熱補償機構,可保證工作溫度狀態下,篩板固定牢靠,篩板拆裝也比較方便。
Working principles and features
    SZR series hot mining vibrating screen is a type of installation, the biaxial vibrator vibration.Biaxial vibrator two axis respectively by two electric motors to drive do reverse self synchronous rotation, makes the screen box produce do linear vibration.Motor installed in the fixed bracket on the side of the screen box, so the motor is not concluded.Between the motor and biaxial vibrator, between two biaxial vibrator adopt universal shaft coupling, universal coupling with Angle and length of the compensation function at the same time, can meet the sieve machine work and the relative displacement between the vibrator motor.
    Depending on the position of the motor and the vibrator is installed, heat ore vibrating screen can be set into vibration type or under vibration pattern.SZR series hot mining vibrating screen are equipped with the secondary vibration isolation system, on the basis of the dynamic load is small, used in vibration isolation vibration reduction requirements, installation height allowed.
    Hot ore screen box side plate and beam is made of high quality heat-resistant stainless steel or high quality heat resistant steel manufacturing, the main force plate and side plate connection, side plate and beam connections using ring groove rivet, reliable connection fastening.
    Hot mining vibrating screen is working, sieve plate directly contact with high temperature materials, has good abrasion resistance, heat resistance, heat resistant alloy steel casting is adopted.Work sieve plate heat expansion, sieve plate fixation device adopts oblique clamp, and is equipped with thermal compensation mechanism, can guarantee the working temperature conditions, sieve plate fixation, sieve plate dismantling is convenient.
