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.

5 Ways to Solve Bucket Elevator Ash Leakage

(1) Whole Casing flange gasket of bucket elevator damages or no flange gasket, please change new gasket, glue with the sealing glue, retighten the flange bolts.
(2) If material leaks from the head section and bottom base gap, please add a gasket or sealant.
(3) If altitude difference is too large, it will increase material feeding pressure, please change the material feeding method, add a feeding buffer device.
(4) Drive chain occurs idle rotation, please adjust the chain length. 

(5) Casing installation is not straight, please adjust perpendicularity of the casing length. 

Bucket elevator conveyor system equipment

Bucket elevator is one of the most commonly used lifting equipment with the advantages of high throughput, high lift height and smooth running.When using bucket elevator,the cooperation methods between bucket elevator and upstream equipment should be noticed,please see it as follows:
a.Hand feeding: the material in the bag can be fed into the conveying equipment through the feeding port. 
Advantage:The lifting machine can run normally without material blockage.
Disadvantage: Hand feeding required higher physical strength.

b. Feeding through Bin connected with chute: the feeding method saves human cost. Loading machine and vibration hopper are allowed under available working condition, hopper can store material and also brings buffer function, which will avoid overload problem because of too much material.

c. Common feeding and conveying equipment: belt conveyor, screw conveyor, scraper conveyor and so on.

Select the bucket elevator What should pay attention to?

Bucket elevator is widely used, the type is an important part of choice. What are the considerations in the selection process of the bucket elevator in it?
1. Taking into account the feed is uneven, uneven material block size and other factors, in selecting hoist, lift amount of margin should be bigger;
2. General bucket elevator tape as an ordinary rope wire rope heat tape and tape, rope tape suitable for general below 80 ℃ materials, heat-resistant wire rope tape applied to below 120 ℃ materials;
3. The bucket elevator has a head housing flange for dust, such as conveying powder materials can be accessed by a large dust collector;
The head of the housing 4. The bucket elevator drive bracket installation and servicing platform, without a separate foundation. Users may need to indicate whether you want to access platform;
5. If the selection please provide the following parameters: the desired height, material type, size, density, temperature, moisture, feeding device name, for indoor or outdoor;
6. delivery Fly - class materials, bucket speed ≤1.3 m / sec, the transmission part an extra design.

Do You Really Know the Safe Installation of Bucket Elevator

1.The bucket elevator must be securely mounted on a solid concrete foundation. Concrete foundation surface should be flat and present as a horizontal state to ensure well-installed bucket elevator can achieve vertical requirements. Middle and upper casing section of a higher height bucket elevator should be connected with the neighbouring buildings in order to increase its stability. Firstly, please install the lower part, fix the anchor bolt, and then install the middle casing and upper casing. After complete the installation, please adjust and correct the vertical height, upper and lower shaft should be parallel to each other, and shafts should be in the same plane. When install the bucket elevator with a lower height , you can connect the upper ,middle and lower casing well first on the ground, and then hang the complete set vertically and fix it on the concrete foundation.

 

2. After completing the installation of casing, you can install the chain and bucket. The u-shape screw which is used for connect the buckets, it is not only a chain connector, but also a fixture of buckets. U-screw nuts must be tighten and locked securely, after the installation of chain and bucket, please adjust it to get a proper tension.
3.Add the appropriate amount of oil or grease in the gearbox and bearing respectively, reducer should be lubricated with industrial gear oil, bearing seat can be lubricated with calcium or sodium base grease.
