Multi-source solid waste direct combustion blending combustion system

Technical Field

The utility model belongs to the technical field of the rubbish waste material is handled, a mix the burning system, especially relate to a multisource is useless directly fired and is mixed burning system admittedly.

Background

The solid waste refers to solid and semisolid waste materials which are produced in production and construction, daily life and other activities and cannot be utilized in a certain time and place and are discarded to pollute the environment. Urban solid waste is generally divided into the following categories: 1. municipal solid waste; 2. general industrial solid waste; 3. domestic sludge. The solid waste can be transformed chemically, physically or biologically under certain conditions, so that the surrounding environment is influenced to a certain extent, and if the adopted treatment method is improper, harmful substances pollute the environment and harm the health of human bodies through water, gas, soil and other ways.

Therefore, people design a solid waste and biomass direct-combustion coupling utilization system and process, and apply for Chinese patents with the application numbers as follows: 201911231716.1, respectively; the publication number is as follows: CN 110762534A; this system can be directed against and mix the production line of burning of mixing that burns the waste material including solid-state waste material of industry and living beings and carry out integration, automation, intelligent management, mix the waste material of burning and get into and mix and burn the production line after, send the breaker breakage to the chain trigger earlier, reach the transmitter back through the belt conveyor again, blow in the boiler pan feeding mouth by the wind pressure that the roots's fan of transmitter produced and burn. This system is earlier with the breaker with the waste material breakage become can be blown by roots's fan small granule material, insufflate the boiler with small granule material waste material by roots's fan again and burn, and the pay-off is efficient, and can not lead to the fact the influence to the operation of burning of boiler.

In the pay-off in-process of this system, need earlier send higher feed bin top through chain trigger and belt feeder solid-state waste material, fall to the sender along the feed bin by solid-state waste material under self action of gravity again, just blow solid-state waste material to the boiler by the roots's fan at last and burn.

However, some light wastes which are loose and have large volume such as cloth and leather are also contained in the solid wastes, after the solid wastes are crushed into small particles by the crusher, the solid wastes have lighter texture and are easy to accumulate in the storage bin, and even converge together under the influence of factors such as static electricity and the like without falling down to the direction of a material pipeline.

SUMMERY OF THE UTILITY MODEL

The utility model aims at the above-mentioned problem that prior art exists, provide a solid useless direct combustion of multisource mixes burning system, solved the problem of light waste material unloading inefficiency among the current solid useless processing system.

The purpose of the utility model can be realized by the following technical proposal:

the multi-source solid waste direct-combustion blending combustion system comprises a feed bin with a feed opening, a fan and a blowing pipeline connected to the fan, wherein the feed opening of the feed bin is communicated to the blowing pipeline through a feed pipe.

When this multisource is useless directly burning and is mixed burning system uses, will smash the solid useless transport of back to the feed bin in store, make its helical blade will be useless admittedly to its discharge end direction propelling movement through the rotation of screw feeding spare and until useless admittedly enter into the unloading intraductally.
