The invention provides a production device for a urea formaldehyde sustained-release compound fertilizer. The upper and lower ends of a reaction cavity are provided with cylinder necks. The cylinder necks drive the reaction cavity to rotate, an exhaust port is arranged above the cylinder necks, a hollow shaft and a formaldehyde solution feeding pipe are inserted into the middle of the cylinder neck at the upper end of the reaction cavity, and a stirring blade is arranged at the portion, inside the reaction cavity, of a shaft rod of the hollow shaft. A plurality of formaldehyde spraying holes are uniformly distributed in the stirring blade. A urea feeding hopper is arranged at the upper portion of the reaction cavity. The bottom of the reaction cavity is provided with a transverse stirring shaft and a longitudinal stirring blade. A urea formaldehyde reaction solution outlet is formed in the middle of the bottom of the reaction cavity. A coil heat exchanger is arranged at the lower portion inside the reaction cavity. According to the production device of the compound fertilizer, in the production process, the formaldehyde solution enters a reactor in a dispersed mode and mixed with urea during stirring; meanwhile, a silencing pot is further arranged on the reactor, so that mental and physical health of workers is protected.
Description
technical field [0001] The invention belongs to the technical field of chemical fertilizer production equipment, and in particular relates to a urea-formaldehyde slow-controlled release compound fertilizer production device. Background technique [0002] In the production process of urea-formaldehyde slow-release fertilizer, various raw materials such as urea and formaldehyde need to be mixed and reacted to produce the required substances. Due to damp and other reasons during storage, urea is easy to agglomerate and form lumps of different sizes. The existing urea The agitator of the formaldehyde reaction device runs at a fast speed, makes a lot of noise, the material flow path is relatively single, the stirring effect is not ideal, and the large pieces of urea are not easy to dissolve and decompose, so that the reaction is uneven, which affects the improvement of product quality; at the same time, the current controlled release fertilizer The production equipment is complex...
