Abstract

The invention discloses a volatile matter leakage preventing reaction barrel and relates to fertilizer producing equipment. The volatile matter leakage preventing reaction barrel comprises a shell, a urea smashing part and a stirring shaft, wherein a formaldehyde feeding opening is formed in the upper end of the shell; the urea smashing part comprises a smashing barrel, a smashing impeller, a linkage mechanism and a feeding piston; the smashing barrel is fixed to the upper end of the shell, the lower portion of the smashing barrel is arranged in an inner cavity of the shell, and a one-way feeding valve is arranged at the lower portion of the smashing barrel; a urea feeding hopper is arranged at the upper end of the smashing barrel, the feeding piston is in slide connection in the smashing barrel, the smashing impeller is in rotary connection with the smashing barrel, and the stirring shaft can drive the smashing impeller to rotate through the linkage mechanism; the smashing impeller rotates to drive the feeding piston to slide up and down in a reciprocating mode, a material leaking hole in a reversed frustum shape is formed in the feeding piston, a plug matched with the material leaking hole is arranged under the material leakage hole, and the lower end of the plug is connected with a spring. In material feeding, the urea smashing part of the device can prevent irritant volatile gas from diffusing outwards through the urea feeding hopper.

Description

technical field [0001] The invention relates to a chemical fertilizer production equipment, in particular to a reaction cylinder for preventing leakage of volatile matter. Background technique [0002] In the production process of urea-formaldehyde slow-release compound 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. Some urea-formaldehyde reaction devices do not have a crushing mechanism, and large pieces of urea are not easy to dissolve and decompose, so that the reaction is uneven and affects the quality. [0003] The application number is 201410136351.5 Chinese patent discloses a reaction device for the production of urea-formaldehyde slow-release compound fertilizer; it includes a housing and a stirring shaft arranged in the housing. The upper end of the stirring shaft extends to the...
