Jin Kai Company Achieves Real Results in Reducing Costs and Increasing Revenue Author/Source: Henan Petrochemical News Network Date: 2021-10-21 Clicks: 16 Since the beginning of this year, Jin Kai Company, part of Jinneng Holding’s Equipment Manufacturing Group, has made concerted efforts to tap into internal potential, focusing on innovation as a means to reduce costs and increase revenue. By leveraging \"five types of minor innovations,\" it has carried out comprehensive technical efforts targeting the key points, challenges, and critical aspects related to minor improvements and cost-saving measures, thus making cost reduction a regular practice. Small changes bring benefits – “This row of nozzles is now working properly, and the misting effect is quite good.” The next step is to modify the other two rows of nozzles in order to improve dust removal efficiency. ”The technician in the company’s raw material workshop pointed to the rows of nozzles above their heads and said excitedly. To reduce the dispersion of the large amount of dust generated during coal unloading, the raw material workshop installed high-pressure atomization dust removal equipment at the site where trucks unload coal. At the beginning of operation, the equipment achieved good dust removal performance; however, as time passed, the nozzles located above the coal powder gradually became clogged by calcium deposits in the water, which reduced the dust removal efficiency. Eventually, thousands of yuan had to be spent on replacing these nozzles with new ones. To this end, after numerous attempts and calculations, the workshop added a new water supply pipe at the front end of the original pipe, connecting it to the existing pipeline. Hydrochloric acid of appropriate concentration is then added regularly to carry out acid-base neutralization and soften the water quality. Additionally, the nozzles are removed monthly and soaked in dilute hydrochloric acid of a certain concentration; after cleaning out the dirt inside them, they are reinstalled for use. By adjusting the height of the nozzles as well as their aperture and spraying direction based on the actual conditions on site, the dust removal efficiency has been **improved** over the original level, and the technical improvements have achieved the desired results. After the modification, the new dust removal system can operate stably for over half a year, saving nearly 30,000 yuan in costs related to replacing nozzles. This has significantly reduced the negative effects caused by dust dispersion during coal unloading and improved the working conditions on site. Self-maintenance helps reduce costs. The nitric acid production workshop is equipped with 3 weighing devices for measuring raw materials; among them, the weighing device for Raw Material No. 1 has a significant deviation in its designed conveying capacity. When producing formulas with low phosphorus and potassium levels, high nitrogen content, or fewer additives, it is not possible to control the minimum amount of material conveyed by this weighing device. This issue becomes particularly apparent when producing triple-component fertilizers, which require 3 to 5 different solid raw materials, resulting in insufficient storage capacity and weighing devices. As a result, manual weighing is necessary, leading to large errors, increased waste of nutrients, and a higher rate of defective products. The Party members and cadres in the nitro compound workshop held several special meetings to discuss feasible solutions. Eventually, an old weighing scale was acquired; the weighing sensor from the previously unusable #1 scale was removed and installed on this old scale. Through the joint efforts of electrical and instrumentation technicians as well as workshop staff, this old weighing scale, which had been idle for 15 years, was able to resume its function in a new role. At present, after multiple physical calibrations, the accuracy of this scale has reached 100%, which meets the normal requirements of production and saves the company over 280,000 yuan in costs.
