A chemicals manufacturer, O Corporation consulted us, explaining, “We want to collect and remove crystals easily even with a top-discharge centrifuge.” We proposed and supplied the KMβ top-discharge centrifuge with the lower part of the water removal bag released and with no basket rim.
As a result of using our centrifuge, the customer was pleased to tell us:
・The operator workload was lightened
・The cleanability of the basket inside the machine increased.
With a top-discharge centrifuge, the operator does not need to remove solids by hand. However, this is fairly heavy work, and if the solids are hard, then the severity increases. Furthermore, in the case of a medium-sized machine of around 42″, the removed solids weigh more than 100kg.
To lighten this heavy work, we came up with the water removal bag which is released in the lower part.
A top-discharge centrifuge uses as the filter medium a water removal bag which is a bag-shaped cloth filter, and attaching or removing this also requires manual work. However, with a water removal bag with the lower part released, the belt attached to the bag can be caught with the crane hook as is, and it can be lifted up as is from the basket. We maintain the height and move it, and untie the bottom of the bag above the container that captures the solids. By doing this, the solids fall from the released part of the bag and can be discharged, so the operator’s workload is lightened.
But, even with a water removal bag with a released lower part, when lifting it from the basket, it often catches the rim, which is often annoying for the operator carrying out the task. Therefore, we devised a rimless basket that is easy to lift, by removing the rim from the basket, and instead attaching a rim to the water removal bag. Due to this, during the task of loosening the solids, the bag no longer catches on the basket rim when lifted, and this leads to increased cleanability of the basket.
Key Points – The operator workload is lightened
Water removal bag with lower part released
By making the lower part of the water removal bag releasable, the weighty water removal bag can be lifted by crane and the crystals can be easily collected.
We also provide a device called a lifter that can lift the water removal bag.
With a normal crane, there is the possibility of the crane’s paint peelings or dust entering the product, which raises the risk of contamination.
Our lifter can be made from stainless steel with prevention of mixing of foreign matter in mind.
Key Points – Basket cleanability increased
No basket rim
By eliminating the basket rim, when carrying out the task of loosening the solids, the bag no longer catches on the basket rim when lifting it, and the basket cleanability is also increased.
