TD-D bucket elevator

TD-D bucket elevator product overview:

The TD type bucket elevator is designed and manufactured according to the JB3926-85 "Vertical Bucket Elevator" standard. Currently, the commonly used bucket elevators in China are vertical and relatively new. Widely used in metallurgy, chemical industry, building materials, mining, grain and oil, food, feed, plastics, pharmaceuticals and other industries.

Basic structure of TD-D bucket elevator:

The TD bucket elevator consists of a running part (hopper and traction belt), an upper section with a transmission drum, a lower section with a tension drum, a middle casing, a driving device, a reverse braking device, etc. It is suitable for conveying loose density ρ<1.5t/m3 powder, granular and small block shaped non abrasive and semi abrasive bulk materials, such as coal, sand, coke powder, cement, crushed ore, etc. upwards.

TD type bucket elevator structure form: The transmission device of TD type bucket elevator has two forms, each equipped with YZ type reducer ZQ (or YY) type reducer. The YZ type shaft reducer is directly installed on the main shaft head, eliminating the need for transmission platforms, couplings, etc., making the structure compact and lightweight. Moreover, it has a special-shaped roller backstop inside, which is reliable. The reducer has low noise, operates smoothly, and floats with the spindle, which can eliminate installation stress.

Main features of TD-D bucket elevator:

1. Low driving power, adopting inflow feeding, induction unloading, and large capacity hopper dense layout There is almost no material return or excavation during material lifting, so there is less ineffective power.

2. The lifting range is wide, and this type of lifting machine has fewer requirements for the types and characteristics of materials. It can not only lift general powder and small particle materials, but also improve materials with high grinding properties Good sealing and minimal environmental pollution.

3. Good operational reliability, advanced design principles and processing methods ensure the reliability of the entire machine, with a fault free time exceeding 20000 hours. Raise the height high The hoist runs smoothly, so it can achieve a high lifting height.

4. Long service life, the feeding of the elevator adopts an inflow type, without the need for digging with a bucket, and there is little squeezing and collision between materials. This machine is designed to ensure that materials are less scattered during feeding and unloading, reducing mechanical wear and tear.

Note: 1. The bucket capacity in the table is calculated, and the conveying capacity is calculated based on a filling factor of 0.6.

2. The purpose of the hopper of the bucket elevator is:

Shallow hopper: Conveys materials that are damp, prone to clumping, and difficult to throw out. Such as wet sand, wet coal, etc.

Deep hopper: Conveys dry, loose, and easily thrown materials. Such as cement, coal, crushed stone, quartz sand, etc.

Supplementary materials for bucket elevator (for user reference): Bucket elevator is used to vertically lift block and granular materials such as limestone, coal, gypsum, clinker, dry clay, as well as powdered materials such as raw materials, cement, coal powder, etc. that have passed through the crusher. According to the speed of the hopper operation, bucket elevators can be divided into three forms: centrifugal unloading, gravity unloading, and mixed unloading. Centrifugal unloading has a fast bucket speed and is suitable for conveying materials with low grinding properties such as powder, granular, and small pieces; The bucket speed of gravity unloading is slow, suitable for conveying block shaped, high specific gravity, and highly abrasive materials such as limestone and clinker. The traction components of bucket elevators include ring chains, plate chains, and adhesive tapes. The structure and manufacturing of the chain are relatively simple, and the connection with the hopper is also very firm. When conveying materials with high abrasiveness, the wear of the chain is small, but its own weight is large. The plate chain structure is relatively sturdy and has a light weight, making it suitable for elevators with large lifting capacity. However, the hinged joints are prone to wear, and the structure of the adhesive tape is relatively simple, but it is not suitable for conveying materials with high abrasiveness. The temperature of ordinary adhesive tape materials does not exceed 60 ° C, steel rope tape allows material temperature to reach 80 ° C, heat-resistant tape allows material temperature to reach 120 ° C, and the temperature of materials conveyed by ring chains and plate chains can reach 250 ° C

Our factory can also design and manufacture special models and specifications of elevators according to user needs.

Model selection of bucket elevator:

As a commonly used lifting equipment, the selection of bucket elevators is constrained by many factors, and choosing the wrong model can bring endless trouble to the user. The selection of bucket elevator generally depends on the following factors: 1. Material form: whether the material is in powder, particle or small block form. 2. Physical properties of the material: whether the material has adsorption or viscosity, and whether it contains water. 3. Specific gravity of materials: Generally, the parameters of bucket elevators are designed and calculated for materials with a stacking specific gravity of 1.6 or less. For materials with a high specific gravity, calculations of traction force and tensile strength of the transmission part are required. 4. Transport volume per unit time.

Generally speaking, the form of the material directly determines the unloading method of the material. The common rule is that powdery materials are unloaded by centrifugal ejection, and block materials are unloaded by gravity. The different unloading methods determine the different hopper forms used in bucket elevators. Centrifugal ejection unloading mostly uses shallow and curved buckets, while gravity unloading requires deep buckets. The material conveying capacity per unit time varies depending on the type of hopper used in the bucket elevator. The final conveying capacity of a bucket elevator depends on a comprehensive parameter of hopper form, hopper speed, material density, material properties, and hopper quantity. The selection process is as follows: material density → transmission mode (bucket lifting model) → material properties → unloading method → hopper form → lifting capacity of the series of bucket elevators → determining the model.

Guidelines for selecting bucket elevators:

1. Material name

2. Material characteristics

a. Particle size (mm)

b. Density (t/m3)

c. Temperature (℃)

d. Humidity (percentage of moisture content)

e. Liquidity

3. Conveying capacity Q (m3/h or t/h)

4. Lift height H (m) (distance between the inlet and outlet of the hoist)
