Special drying project for glyphosate

Project description:
Glyphosate, also known as herbicide, is a non-volatile white solid with a specific gravity of 0.5. It is a non-selective, non-residue herbicide. It is very effective against perennial root weeds. It is widely used in rubber, mulberry, Tea, orchards and sugarcane fields.
In view of the characteristics of glyphosate drying process, the company has developed a special Dryer for glyphosate flash evaporation. The special dryer for glyphosate is a new type of Drying Equipment developed by our company and the Shenyang Chemical Research Institute of the Ministry of Chemical Industry on the basis of digesting and attracting foreign equipment and technologies to dry paste-like, filter-cake-like and heat-sensitive materials.


Device Description:
The hot air enters the bottom of the dryer tangentially, and forms a strong rotating wind field driven by the agitator. The paste material enters the dryer from the screw feeder. Under the strong action of the high-speed rotating stirring paddle, the material is impacted and dispersed under the action of friction and shearing force. ,dry. The dehydrated dry material rises with the hot air flow, and the large particles are intercepted by the grading ring, and the small particles are discharged from the center of the ring to the outside of the dryer and recovered by the cyclone separator and dust collector. , fall back to the bottom to be crushed and dried.

Features:
The Flash Dryer has the advantages of high technology content, high standardization, environmental protection, safety, low consumption, simple maintenance, etc. In the design structure:
①The bottom of the dryer is equipped with an inverted cone structure, so that the drying gas flow section gradually expands from bottom to top, the bottom airflow is relatively large, and the upper airflow is relatively small, so as to ensure that the large particles in the lower part are in a fluidized state, and the small particles in the upper part are in a fluidized state. The particles are also in a fluidized state, and the hot air rotates along the vertebral body, which increases the wind speed at the bottom, reduces the length of the cantilever part of the stirring shaft, and increases the safety and reliability of operation; the bearing can be placed outside the machine to effectively prevent the bearing from being exposed to high temperatures. Zone work, thereby extending the service life of the bearing.
②A scraper is set on the stirring teeth. When the material is crushed by the stirring teeth, it is thrown to the wall of the machine and adhered to the wall. If it is not scraped off in time, the equipment will vibrate in severe cases, and even cause the agitator to stop rotating. . The scraper is set on the stirring teeth, which can peel off the material sticking to the machine wall in time to avoid sticking to the wall.
③The rotation of the stirring shaft is controlled by the stepless speed regulating motor. Select different rotating speeds according to the product particle size requirements. The faster the stirring shaft rotates, the smaller the particle size of the product.
④A classifier is set on the upper part of the dryer. By changing the hole diameter of the classifier and the height of the classification section, the air flow rate is changed to control the size and quantity of particles leaving the dryer, the final moisture content and the residence time of the material in the drying section.
⑤The number of revolutions of the screw conveyor of the feeder is controlled by an inorganic speed-regulating motor. The feeding speed is controlled according to the material properties and drying process parameters.
⑥ The equipment has a compact structure and a small footprint. It integrates drying, crushing and classification. It is an organic combination of swirl technology, fluidization technology, spouting technology and convection technology. The production process saves power and equipment costs.
