Urea bulk storage tank
Thread Content
Dear friends of Dahuaxia: What is the difference between setting up a urea device with a scattered storage system and without one? 1: Investment; 2: Operation and management; 3: What is the significance in actual use? 4: What is the difference between having and not having these settings in the packaging section’s configuration?
The bulk urea storage tank is a water reservoir, a buffer tank.
1. It has been set up to serve as a buffer. The traditional operating mode of the packaging system is three shifts with two rotations, without a night shift. At this point, the urea can be stored directly in the bulk warehouse, awaiting packaging during the day ； Furthermore, even during normal production, the urea system can experience a temporary decline in product quality due to backflow nozzle cleaning, start-up and shutdown operations, or other factors. At this time, the products can also be temporarily stored in the bulk warehouse, with this portion of products gradually being mixed into the regular products in the future ； The downside is: increased investment, and urea stored in open warehouses tends to absorb moisture and become powdery ； 2. No setting: There will be no opportunity for buffering. This requires higher operational reliability and redundancy in the packaging system equipment (sewing machines are the most likely to fail, followed by the weighing units), as well as adjustments to the operating mode to match that of the previous system shift. The advantage is: lower investment costs. The money spent on building a bulk storage facility could easily be used to add several more packaging lines. 3. Overall comparison: It is more advantageous to build rather than not build. So, the money that needs to be spent cannot be saved.
In summary, buffering is merely a temporary solution, used only to handle ordinary accidents. The downside is that it requires shift work in the packaging area, which increases the difficulty of managing safety in the factory, especially at night.
It should be determined based on the production location. There are significant investments. It serves as a storage area. Some have a larger packaging capacity.
Haiyou, let’s use the previous one instead; one scattered storage unit can hold the output for seven or eight days
What was said on the third floor is correct – it can serve as a storage area in case there are problems with the packaging line, thus preventing shutdowns. Spent urea is generally divided into two or three areas, one of which is used for storing urea that does not meet the quality standards. When the moisture content, biuret levels, or dust concentration of the urea coming out of the granulation tower are above the allowed limits, it can be temporarily stored in this area designated for substandard products. When the product quality is good, it can be sent to the packaging line for packaging in an appropriate proportion with high-quality urea, which prevents waste due to defective products and ensures that no substandard urea ends up in the packaged products.
The traditional operating mode of the packaging system is three shifts with two rotations, without a night shift. At Haiyou on the 3rd floor, they don’t work during the long night shifts for packaging – I’ve never heard of such a thing before. This method of storage makes it easy for the products to absorb moisture. Generally, when we encounter problems with the packaging, we use an evaporation cycle in the urine tank to address the issue before sending the material to the granulation process. How do other factories handle such situations?
