Intelligent straw smashing system special for converting sludge organisms into humus through aerobic fermentation

Abstract

The invention provides an intelligent straw smashing system special for converting sludge organisms into humus through aerobic fermentation. The system comprises a main machine body, a driving device,rotation blades, a variable-frequency fan, a conveying air pipe, a material quantity control device and a video monitoring device; the main machine body comprises a smashing cavity and a feeding cavity, a material push-in port is formed in the smashing cavity, and the rotation blades are used for rotating and smashing materials in the smashing cavity under driving of the driving device; the upperportion of the feeding cavity is communicated with an inlet of the conveying air pipe, and the material quantity control device comprises a feeding amount detection assembly, a material storage quantity detection assembly and a controller; the controller is electrically connected with the feeding amount detection assembly, the material storage quantity detection assembly and the variable-frequency fan separately, and the video monitoring device is arranged on the main machine body. According to the system, the discharging amount can be automatically adjusted, a feeding bin is prevented from being blocked, and real-time video monitoring can be conducted according to the condition of the discharging amount.

Description

technical field [0001] The invention relates to agricultural machinery technology, in particular to an intelligent straw crushing system specially used for sludge biological aerobic fermentation to transform humus. Background technique [0002] The sludge generated during the sewage purification process of urban sewage treatment plants is mainly composed of starch, protein, fat, fiber and other harmful components. When microbial fermentation is carried out, carbon sources are required as nutrients for microorganisms for fermentation and growth of microorganisms. Generally, the main raw materials used as carbon sources are corn stalks, rice, wheat stalks, flowers, trees, etc. During fermentation, the carbon source (straw) needs to be broken into smaller particles to facilitate subsequent operations such as fermentation and turning. [0003] At present, the crushing of carbon sources such as straw mainly relies on straw crushers. The currently widely used straw grinder main...
