Our deepest impression on sanitation workers is that of the time in the textbook, and the sanitation spirit he represents is particularly valuable in the present era. However, when placed in real life, we are often avoiding such a modern “Shichuan Xiangâ€-â€sucking truck†and “ vacuum suction truck .†Each industry has its own respect, but in the moment People still have an arrogant attitude towards the tools and people who are engaged in this type of cleaning work. Perhaps through the following introduction to vacuum suction trucks, people who do not understand can have more understanding of the sanitation industry. First, vacuum suction trucks and sprinklers, garbage trucks and called the three major sanitation models. Mainly used in septic tanks, sewers and sewage pipelines to clean up the cleaning work of special vehicles. The state has long had related policies and care for help. Second, the main body of the suction truck consists of tanks, vehicle chassis and other elements. Third, suction truck suction pump power comes from the chassis engine engine, engine engine through the gearbox, power take-off, transmission shaft passed to the suction machine, suction suction pumping out the air in the tightly sealed tank body, To make it into a negative pressure, use the pressure outside the tank to press the dirt into the tank through the suction pipe. At the time of blowdown, the air extractor presses the atmospheric pressure outside the tank into the tank and uses atmospheric pressure to discharge the waste out of the tank. Fourth, the flow of air is - suction pump air suction tank with a certain degree of moisture into the steam clutch, where the water is released after the clutch back to the tank, the gas along the pipeline through the four-way valve Into the air inlet of the air pump, mixed with the lubricating oil in the pump through the compression chamber and discharged from the exhaust port. The mixture is separated by the primary filter to obtain preliminary separation. The clutched oil flows back to the oil pump, and the mixture is further clutched by the oil and gas clutch. Then entered the four-way valve to vent the atmosphere. V. The function of the vacuum suction truck is mainly to use the suction machine equipped with the vehicle to suck the wastes that need to be pumped, such as urine, sewage, sludge slurry, and liquids containing minor suspended debris, into the suction truck. The tank body can achieve self-priming, self-priming, fast speed, large volume, and convenient transportation. It is suitable for collecting and transporting liquid materials such as urine, muddy water and crude oil. The above is the construction and working principle of the vacuum suction truck. I hope to make a simple popularization for the friends who saw the article, and also to change the public's prejudice against such professional tools.
The powder granule in the container (fluidization bed) appear the state of fluidization. It is preheated and mixed with clean and hot air. At the same time the solutionof adhesive solvent is fogged and sprayed into the container. It makes some of particles become granulating that contains adhesive. Being of unceasing fry through hot air, the moisture in the granulating is evaporated and the adhesive is solidification. The process is carried out continuously. Finally it forms ideal. uniform and porous granules.
Through powder granulating, the flow property is improved and the dust is reduced;
Through powder granulating, its solving property is improved;
The mixing,granulating and drying can be completed in one step inside the machine;
The operation of equipment is safe because the anti static filtering cloth is adopted;
The operation personnel can not be damaged if explosion take place because of the releasing hole;
The equipment has no deadcorner. Therefore the loading and unloading, quick and light and clean. It can meet the requirement of GMP.
