"In fact, this aquarium is a small wish to complete my high school. At that time, in order to ease the pressure of college entrance examination, I raised a few goldfish, because they did not have time to take care of them, not long after the goldfish died, and later I fantasize If there is an aquarium that can automatically feed, automatically adjust the temperature, automatically change the water is good. "Yesterday morning, at Huanghuai University Chong Ke space, mechanical and energy engineering college of electronic science and technology students Zhang Hao said He had a lot of ideas in high school, but at that time, because of the limited knowledge he learned, he could not realize the dream of a smart aquarium. At university, he completed his wish with the help of a platform for making a living.
High school students like to raise goldfish
High school 3 years of life, many people who have experienced the entrance exam are familiar with: repeat the endorsement every day, mock examinations, in addition to learning outside life or learning. In order to ease the pressure of intense learning, schools or individuals will find ways to decompression. Zhang Hao, who has gone to junior year this year, is relieving himself of using goldfish during his senior year.
Zhang Hao said that he was born in Xinyang Rural Gushi and many high school students, very prosperous on the city. During his high school, he kept telling himself that he had to take a good test at college entrance examination and be an ideal college. In 2013, he entered the "ready state", daily heavy pressure of learning pressure him somewhat out of breath.
"When I was a kid, I was living in rural areas, and I was fond of catching some small fish back to my hometown. When I was particularly nervous in my senior year, I bought 3 goldfish and kept them in the dormitory. Water, but I always do not have time to take care of them, not long after, the goldfish died. "Zhang Hao said after the death of the goldfish, he tried to raise three, the result is still the same as the first time.
Because of these two failures, Zhang Hao did not continue to fish, but he has always put the fish in mind, when the Internet will be available to see how to keep the fish better. "Later, I learned that fish growth and water quality, feeding, oxygen content in the water, then I would like to, if there is a fish tank to fish automatically, how nice." Zhang Hao said.
Just enter the university to challenge the smart aquarium
In September 2014, Zhang Hao admitted to Huanghuai College with his outstanding achievements. "After entering college, I think my aspirations in high school should be fulfilled." Hao said last semester, he has been working hard to get into the maker's space because of his limited ability. As for the "smart fish tank" In the planning and preliminary preparation stage.
Zhang Hao said that with the accelerating pace of modern urban life, citizens rarely have time to fish and often die of fish because of forgetting to change the water, feeding, oxygenation and so on, which has repeatedly hit their confidence in raising fish. "Nowadays, aquariums for public use no matter how expensive and advanced, people still need to stand beside the fish tank and I want to use the remote control." Zhang Hao said.
Taking into account the aquarium market has greater disadvantages, especially when fish lovers are not at home can not take care of the predicament of the fish at home, resulting in limited fun of fish farming, which can only be limited to a specific time and place.
How to change fish in one way? Zhang Hao has been thinking. "Just like the QQ virtual pet, we can feed, change water, make oxygen and so on through the mobile phone APP." Zhang Hao said.
Create a smart aquarium with the "Internet of Things."
In April 2015, Zhang Hao made his wish to enter the Hutchison Whampoa Institute space. His ability to make rapid progress, thought-rich he began a "fist."
High-pressure Desorption Electrolysis
This series of equipment is oriented to the gold-loaded carbon in the gold cyanide carbon slurry process for gold desorption and electrolysis, and the gold adsorbed on the gold-loaded carbon is produced in the form of high-grade gold mud.
This series of equipment has 3 patented technologies and 5 proprietary technologies. Sodium cyanide is not used in the desorption liquid, which reduces the lean carbon grade below 100g/t. The key technology of this equipment is to ensure the balance of metal content, avoid the phenomenon of equipment "accumulation" and "floating gold", and ensure the stable and stable technical indicators of the equipment. The cost is low, and the content of technological advancement has been broadcast on the Spark Science and Technology column of CCTV in 2000. The technology passed the technical appraisal in 2003 and won the second prize of Science and Technology of the China Gold Association. The overall technical level is domestically leading. In 2006, it was designated as an energy-saving technology for gold production by the National Development and Reform Commission. In 2007, it was designated as an industry standard equipment by the National Development and Reform Commission. The equipment has obtained 3 Chinese patents, the patent numbers are: 01241537.5 01241538.5 200620029209.1
