Description

A kind of mud drying device

Technical field

The utility model is related to sludge drying device, especially a kind of mud drying device.

Background technology

With the development of urban construction, growth in the living standard, the growing amount of municipal sludge is also increasing, with the passing of time Pile up and very affect urban environment and air quality.The method carrying out batch processing to municipal sludge at present is generally physics Method and biochemical method, physical method is typically drying and other treatment, that is, remove contained most moisture in mud, then to surplus Remaining slag charge carries out harmless treatment or switchs to his use.Physics drying and other treatment mode advantage compared with biochemical treatment mode is notable, As little in processing equipment area occupied, process cycle is short, energy consumption is low, do not easily cause secondary pollution etc..But, in physics drying and other treatment In mode, typically carry out drying and other treatment firstly the need of to mud raw material, be otherwise difficult to ensure that efficient, high-quality drying and other treatment knot Really.

The sludge drying device occurring on the market, generally comprises charger, mud forming machine, drying dehumidification machine and discharge Machine, wherein mud forming machine are used for for mud being shaped to solid strip-shaped materials, and the technique of forming machine shaping directly affects material Form, the efficiency of shaping, in addition impact sludge drying product efficiency of combustion；Drying dehumidification machine is used for carrying out strip-shaped materials Drying dehumidification, the effect of drying dehumidification directly affects the energy consumption of whole equipment, and the aridity of sludge drying product, also can shadow Ring the efficiency of combustion of sludge drying product.Generally speaking, the mud forming machine in sludge drying device and drying dehumidification machine are to pass Important.

Existing mud forming machine generally comprises dress mud box, forming cylinder and the rabbling mechanism being arranged in dress mud box, due to Mud viscosity is larger, and mud can be beaten loose by rabbling mechanism, enables mud to enter forming cylinder.As China Patent Publication No. For 203620693 and a kind of sludge crushing forming machine, include sewage sludge feed storehouse, be provided with from top to bottom in sewage sludge feed storehouse A pair broken mud roller and the compressing roller of a pair of mud bar, two broken mud rollers are parallel to each other and surface is formed with interlaced broken mud and props up Fork, two broken mud rollers are provided with, with end, the gear being meshed, and gear is driven by variable-frequency motor, and the compressing roller of two mud bars is mutual Parallel and engage, the compressing roller of two mud bars is also provided with, with end, the gear being meshed, and gear is driven by variable-frequency motor.Due to Chinese patent, a kind of Split type sludge of Publication No. 205056166 crushes shaped device, include support, crushing mechanism and Shaping mechanism；This support is provided with two broken baffle plates, is formed with accommodation space, the input port of accommodation space between two broken baffle plates Upward, the output mouth down of accommodation space；This crushing mechanism is arranged on support and is located in accommodation space, and crushing mechanism includes There are broken driving shaft and broken driven shaft；This shaping mechanism is arranged on support and is located at the lower section of the delivery outlet of accommodation space, Shaping mechanism includes shaping drive roll and shaping driven voller.Rabbling mechanism in these mud forming machines is similar, is all For stirring mud so as to become loose, but after mud is broken up, its viscosity is still very big, only relies on the weight of mud itself Power is difficult to smoothly enter in forming cylinder and is molded；Gap between loose mud is big, and mud is after forming cylinder It is also often desultory, shaping mud out is not sufficiently strong, easily scatter when transport is dried, have a strong impact on dirt Product quality after the follow-up mummification of mud.Further, since rabbling mechanism is big with mud contact area, and mud weight itself is heavier, Such that rabbling mechanism load becomes big, the motor of stirring-head is driven easily to burn.

Content of the invention

Technical problem to be solved in the utility model is to provide a kind of mud drying device, and mud Forming Quality is good, effect Rate is high.
