1. Technical Features

The NSE series high-speed plate chain bucket elevator is our company adopts serialization, standardization, and modular design concepts, and optimizes the design of the plate sleeve roller chain as the traction part of the vertical elevator. It is not only suitable for lifting general powder, small particles and small lump materials, but also can lift abrasive materials. Lifting capacity: 65~ 2300m3/h; operating speed ≤1.2m/s, lifting height ≤65m, material temperature ≤250℃.

(1) The transmission system adopts high-efficiency energy-saving motor supporting imported gearbox and magnetic coupling direct drive;

(2) Meet the requirements of full load and heavy load start, optional split manual auxiliary transmission; Equipped with Portland/Ketten-Wulf chain to ensure that the minimum safety factor of a single chain is more than 12 times;

(3) The chain and sprocket adopt standard forms and do not make non-standard designs; there are standardized supporting schemes for non-standard design products of the same industry, so that customers will no longer increase investment for non-standard products;

(4) The tail of the elevator adopts two types of internal and external tensioning devices; the head and tail wheels are all set to a split structure, which is easy to repair and replace.

2. Basic structure

The plate chain elevator is composed of running parts, driving device, head device, middle casing and tail device. The running parts are composed of bucket, chain and bolt components. The chain is the traction part of the elevator and one of the main load-bearing parts of the equipment. It is composed of multiple chain links. Each chain link is composed of a chain plate, a pin, a pin sleeve, and a roller. It is assembled into a 2~3 meters strip in the factory and assembled into a closed chain link on site.

Basic work flow: elevator inflow feeding, induced unloading, intensive arrangement of large-capacity buckets. When the material is lifted, there is almost no material return and digging phenomenon, and squeezing and collision between the materials rarely occur. The design of this machine ensures that the material is rarely scattered during feeding, lifting and unloading, which reduces the mechanical Wear, using plate chain type high-strength wear-resistant conveyor chain, greatly extending the service life of the chain and bucket.
