Sludge powder mixing machine

Abstract

The invention discloses a sludge powder mixing machine which comprises a motor A, a worm and gear speed reducer, a coupling C, drum shafts, drums, a chassis, a motor B, a coupling D, driven rotor shafts, driven rotors, powder mixing knives, a belt pulley, a belt, a rack, driving rotors and driving rotor shafts, wherein a pair of parallel drum shafts, a pair of parallel driven rotor shafts and a pair of parallel driving rotor shafts are sequentially arranged in the chassis from top to bottom, and the driven rotor shaft and the driving rotor shaft which are arranged in an up-down adjacent mode are driven by using the belt; the motor A is arranged on the rack and drives the drums to run oppositely at a low speed; the motor B is arranged on the rack and drives the driving rotors to run oppositely at a high speed; and multiple powder mixing knives which are installed in a horizontal staggered and / or up-down staggered mode are respectively arranged on the driven rotors and the driving rotors. The sludge powder mixing machine has the functions of grinding, crushing, mixing, throwing and the like, and can treat sludge materials quickly and conveniently; and the sludge powder mixing machine is widely applicable to urban sludge treatment.

Description

Technical field [0001] The invention relates to a sludge powder mixer. Background technique [0002] As the scale of cities continues to expand, the environmental problems caused by urban sewage sludge have become increasingly prominent. In the composting process for aerobic fermentation of urban sludge, the sludge, conditioner, and return material need to be proportioned according to set proportions. Only after the machine is stirred can the process requirements of aerobic fermentation of the sludge be better satisfied; due to the physical and chemical properties of the sludge and the storage process, it is easy to be mixed with impurities, which is not conducive to the operation of the general-purpose grinder. The mixture formed by general crushing and mixing The process requirements of aerobic fermentation are not met, and anaerobic fermentation is formed in the aerobic fermentation process, which produces foul odor and pollutes the environment; while the ordinary sludge grind...

Problems solved by technology

[0002] With the continuous expansion of the city scale, the environmental problems caused by the sludge after urban sewage treatment have become increasingly prominent. In the composting treatment of urban sludge aerobic fermentation, it is necessary to use sludge, conditioners, and return materials in a set proportion The technical requirements of sludge aerobic fermentation can be better met only after being stirred by a machine; due to the physical and chemical characteristics of sludge and the process of stacking and storage, impurities are easily mixed in, which is not conducive to the operation of the general pulverizer, and the mixture formed by general pulverization and mixing It does not meet the technical requirements of aerobic fermentation, and anaerobic fermentation is formed in the process of aerobic fermentation, which produces stench and pollutes the environment; while the structure of ordinary sludge pulverizers requires simple materials, and dewatered sludge is a kind of sandy sludge. , flocculated substances with a lot of impurities and a moisture content of 80%, it is difficult to mix the conditioner with fine particles and low density evenly with it, and it will form agglomerates after crushing, causing the blades of the tear-shear pulverizer to wear quickly and difficult to replace, and the hammer Impact-type mixing and crushing are not uniform, the work efficiency is low, and the use effect is not good
