TB series plate chain bucket elevator
TB series plate chain bucket elevator
TB series plate chain bucket elevator is suitable for transporting materials in state of powder, granule, small piece abrasive material and non-abrasive material, such as raw material, cement, coal, limestone, dry hard clay and clinker, etc. Materials temperature is controlled under 250℃. This series elevator adopts feeding input and guiding discharge. Materials feeding into the hopper are elevated to the top area by plate chain then discharged automatically by action of gravity. Its main technical parameters accord with standard of Ministry of Machinery (JB3926-85). TB series plate chain bucket elevator is new-style product introducing foreign advanced technology. Because of energy-saving and high-efficiency, it is replacing gradually HL type equal-ring-chain elevator. The chain is made in high-quality alloy steel with features of high strength, wearable and reliable. The driving device adopts hard tooth face reducer.
Characteristics of TB series plate chain bucket elevator:
1、 Good sealing, less environmental pollution.
2、 Convenient for operation, maintenance, less wearing parts.
3、 Energy saving, less maintenance, low cost.
4、 Reliable operation, advanced design.
5、 Good structure rigidity, high precision, the shell is edged, rib pressed, and then welded to get good rigidity and good appearance.
6、 Compared with other kind of elevator with same elevating capacity, its mechanical dimension is smaller.
7、 Large transporting capacity. TB series has TB200～TB1100 kinds of specifications, elevating range is 4.5～2745m3/h. Low energy consumption, low noise and long lifetime.
Main structure and features of TB series plate chain bucket elevator:
TB series plate chain bucket elevator is composed of running parts, driving device, upper device, middle shell and bottom device.
1、 Upper device: Double-row railway is installed to prevent swinging of the chain, backstop is installed to prevent turning of the hopper. There is rubber plate installed at discharge outlet to avoid feeding back.
2、 Middle node: Double-row railway is installed on partial middle node to prevent swinging of the chain during running. Maintenance gate is installed on partial middle node for convenience of checking.
3、 Bottom device: Tensioning device is installed, elevators of TB200~TB400 adopt spring tensioning, elevators of TB500~TB1100 adopt weight box tensioning.
4、 Upper and bottom chain wheel adopt ZG310-570. Integral hardening and tempering HB229-269, hardening of tooth face HRC40~48.
5、 Plate chain: it adopts 45 # HRC36~42.
6、 a、Plate chain adopted has high shear strength, fatigue strength and wear resistance, low running failure rate and long lifetime. b、low chain speed (0.5m/s) is adopted. c、It adopts large capacity hopper and short hopper distance, low driving power rate and large transporting capacity.
Features and technical requirements of TB series plate chain bucket elevator:
1、 Inflow-type feeding is adopted, extruding or collision among each part of the elevator or between each part and materials will rarely occur, it is smooth in running and convenient for maintenance.
2、 It adopts surface contact of plate chain, replacing point contact of traditional ring chain, lifetime will be prolonged accordingly, lifetime of plate chain can reach more than five years.
3、 Because adopting inflow-type feeding and gravity guiding discharging, high linear speed (15-30m/min), without feeding back, power rate is just 40% of ordinary ring chain elevator.
4、 High running rate, time between failure can reach above 30000 hours.
5、 Conveying capacity is large, capacity range is 15-800m3/h.
Alloy steel wear-resisting sleeve roller chain and chain wheel:
1、 The chain is made in high-quality materials produced in special steel plant, processed by advanced technology of heat treatment.
1)、Inside and outside chain plate:40Cr ; 2)、Axis pin: 20CrMnMo ;3)、Sleeve: 20CrMo ; 4)、Roller: 20CrMo; Hardening and tempering HB293-365; carburizing and nitriding (0.5mm).
2、Head chain wheel:
1、Structure: it is composed of hub and separated tooth ring.
2、Material: hub G45; tooth ring: 20CrMo forging steel.
3、Technical data: two types, low speed 12 teeth and high speed 24 teeth.
4、Machining method: linear cutting synchronous complete machining, cutting after installation.
5、Method of heat treatment: hardening and tempering on hub:HB217-255; Hardness of surface of tooth ring: HRC55-60.
3、Tail chain wheel:
2、Technical data: toothless lathe finish.
3、Heat treatment: medium-frequency hardening HRC55-60.
