Bucket Elevator with Explosion Safety Protection Device

Frankly speaking, it’s really necessary to install safety protection device on bucket elevator so as to ensure normal operation. Now, what is the significant inspection standard for equipment quality is that to minimize or completely eliminate all kinds of risks. According to structure of bucket elevator, there are many kinds of safety protection device. We can divide into the following protection devices based on their function: explosion safety protection device, running deviation safety protection device, overload, speed measurement and reversion protection device.
Here we will mainly introduce the explosion safety protection device. Because working components of bucket elevator and material running speed are relatively fast, also they are running in the sealing casing, if there are many dusts in materials, it will cause high dust contained. In the grain industry, materials always contain many flammable organic dusts, once dust content is too high, it maybe blast when meeting open-flame. Therefore, both design and application of bucket elevator must consider the explosion precaution.
Main measure: Please leave a dust mouth above the bucket elevator head drive. When conveying materials which will cause dust explosion, at this time please open the dust mouth, install dust collector and reduce dust concentration to make it have no necessary explosion conditions.

How to Check Short Circuit in Winding of the Bucket Elevator

The bucket elevator has the advantage of large conveying capacity, high lifting height and long service time. Many of us would wondering why short circuit in winding happens in the operation, this passage introduces the methods for checking the short circuit in winding in the following:

1. Check the electrical bridge;

Measure the direct-current resistance of winding. The general phase difference should not exceed 5%, if it exceeds, we can confirm that the phase with small electrical resistance has short trouble.

2. Power the elevator and do experiment;

Measure the current by ammeter, short trouble exists where there is high current.

3. Observe the surface of the bucket elevator;

Observe whether there is burn at the connecting box and the winding overhang.

4. Check the temperature of the bucket elevator;

Operate the elevator without load for 20 minutes(power it off immediately if there is any abnormal phenomenon), and touch each part of the winding part to see if the temperature is higher than the normal temperature.

5. Check by the millimeter or the Meg-ohmmeter;

Measure the insulation resistance between two any phase, if it is very low or shows no resistance, then it means there is short trouble here.

4 key factors decide the function of bucket elevator

 Bucket elevator can be installed singly or in a system, in order to meet the needs of the site and materials forms. The main parameter of the bucket elevator is according to the handling system, loading and unloading location conditions, production process and the characteristics of transported material,main aspects are as follows:
1. Conveying capacity: it means the amount per hour, usually calculated in weight or volume.
2. Conveying speed: improving the speed can increase the elevating capacity. Especially when use the belt bucket elevator for long distance transporting,it needs to improve the conveying speed, but if use chain bucket elevator you should not, in case of enlarging the burden.
3. Pats dimension: the dimension of parts include belt width, plate width, bucket volume, channel diameters and so on, these dimensions will have an impact on the conveying capacity.
4. Conveying distance: the total distance will have an impact on the total resistance and power.

Tripper Introduction

tripper

Belt conveyor tripper is a mobile device which can unload materials at the arbitrary point of horizontal section of the conveyor; it’s a single part of the conveyor. Movable tripper can be divided into light-duty type and heavy-duty type.

► Features
    1.Durable
    2.High efficiency
    3.Simple structure
    4.Stable operation
    5.Easy to maintenance
    6.Multiple discharging points
    7.Moving freely with wheels

tail

► Advantage

    1.Heavy duty structural frames and supports – to provide system rigidity

    2.Heavy duty inlet skirting – to eliminate spillage at discharge transition

    3.Abrasion resistant belting – to reduce wear and increase life span

    4.Heavy duty idlers with anti-friction bearings – to increase idler life and reduce horsepower requirements

    5.High torque drive units – to power through upset conditions 

    6.Modular design shipped with limited field assembly required for drop in, bolt in place field installation

    7.May be fitted to any new or existing conveyor

    8.Single and dual side discharge designs

    9.Evenly distribution of materials 

    10.Save storage space

    11.Powered tripper movement through cable/winch assembly or powered wheels, crowned bend pulleys for positive belt tracking 

    12.Shuttling cross conveyor belt design available with side to side movement

    13.Cross over platform/operator deck available on cross conveyor tripper

    14.Engineered to meet new project requirements and also to retrofit existing conveyors

►  Application
XLP Tripper is always used at a large belt conveyor, it applies in the occasion where the belt conveyor has a discharge requirement, such as mining, power plant, steel plant, port, etc.
