Plate chain bucket elevator

Product introduction

Overview of ne series plate chain bucket elevator :
     NE plate chain bucket elevator It is a lifting equipment of plate chain type and gravity induced unloading. It is suitable for vertical transportation of grinding or non grinding materials such as raw meal, cement, coal, limestone, dry clay and clinker.

NE type plate chain bucket elevator is a new type of lifting product developed by introducing foreign advanced technology; ne series plate chain bucket elevator is used in various industrial countries, due to energy saving and high efficiency, NE plate chain bucket elevator is gradually replacing HL Type chain elevator. The ne type plate chain bucket elevator is an inflow feeder. The material flows into the hopper and is lifted to the top by the plate chain. The material is discharged by itself under the gravity of the material. The main technical parameters conform to the standard of Ministry of machinery (jb3926-85).

NE type plate chain bucket elevator adopts self flow charging and gravity discharging. The chain is a high-quality alloy steel high-strength plate chain, wear-resistant and reliable. The driving part adopts hard tooth surface reducer. The elevator is suitable for vertical transportation of medium, large and grinding materials (such as limestone, cement clinker, gypsum, lump coal), and the material temperature is controlled below 250 ℃.

Working principle of ne series plate chain bucket elevator :
Ne series plate chain bucket elevator is an inflow feeder. The material flows into the hopper and is lifted to the top by the plate chain, and the material is discharged automatically under the action of material gravity. This series of hoists have many specifications (11 types of ne15 ~ ne800) with wide lifting capacity, high production capacity and low energy consumption. The machine adopts fully enclosed casing with low chain speed and almost no material return phenomenon. Therefore, it has less reactive power loss, low noise and long service life.

 

 

Features of ne series plate chain bucket elevator :
Good sealing performance.
2. Convenient operation and maintenance, less wearing parts.
Due to the low cost of use and maintenance.
4. Reliable operation and advanced design principle ensure the reliability and good sealing of the whole machine. Less environmental pollution.
5. Structural port model, high precision. The shell is folded and stiffened in the middle, and then welded. It has good rigidity and beautiful appearance.
6. The mechanical size is small. Compared with other hoists with the same lifting capacity, this kind of hoist has smaller mechanical size.
7. Large conveying capacity, the series of hoists have ne15 ~ ne800 specifications. The lifting capacity ranges from 15 to 800 m3 / h.
8. Easy operation, less maintenance and less wearing parts. The conveying chain is sleeve roller chain, which is used for vertical lifting of various powder and block materials.

 


Main structure of ne series plate chain bucket elevator
Ne series plate chain bucket elevator is composed of running parts, driving device, upper device, middle casing and lower device.
The running part is composed of hopper and special plate chain, single row chain is used for ne30 and lower part, and double row chain is used for ne50-ne800.
Driving device --- it is driven by a variety of driving combinations (depending on the actual needs of users). The driving platform is equipped with maintenance rack and railing. There are two kinds of left and right.
The upper device is equipped with rail (double chain), backstop and anti return rubber plate at discharge port.
Intermediate section - some intermediate sections are equipped with rails (double chains) to prevent the chain from swinging during operation.
Lower device - equipped with automatic tensioning device.
Characteristics of main working parts of ne series plate chain bucket elevator :
1. Upper device: track (double row) is installed to prevent chain swing, backstop to prevent hopper rotation, material blocking the lower casing, and rubber plate installed at the discharge port to prevent material return.  
2. Middle section: some middle sections are equipped with rails (double row joints) to prevent the chain from swinging during operation, and some middle sections are equipped with access doors for maintenance.  
3. Lower device: a tensioning device is installed, ne15 ~ ne50 is tensioned by spring, NE100 ~ ne800 is tensioned by hammer box.  
4. ZG310-570 is used for upper and lower sprocket. Whole quenching and tempering, hb229-269 tooth surface quenching hrc40 ~ 48.  
5. Plate chain: chain plate adopts 45 ා hrc36 ~ 42. a. The plate chain adopted has high shear strength, fatigue strength and wear resistance, low failure rate and long service life; B. low chain speed (0.5 m / s); C. large capacity hopper and small bucket distance, low driving power and large conveying capacity. It is especially suitable for lifting crushed limestone and cement clinker (≥ ne50).
