Description

Negative pressure feeding bin dust treatment system Technical Field The utility model relates to the technical field of plastic processing, chemical production and food processing dust treatment, in particular to a negative pressure feeding bin dust treatment system. Background Dust refers to solid particles suspended in air, which are seen almost everywhere in existing life and work, and after weathering the soil and rock breaks up into many fine particles which accompany pollen, spores and other organic particles which drift in the air. In addition, many of the dust is a byproduct of industry and transportation, and the exhaust gas from chimney and internal combustion engine contains a lot of dust, flour, and volcanic ash due to the operation of quarries, etc. Dust floating in the atmosphere often contains a plurality of toxic components, is harmful to human health, is extremely easy to go deep into the lung, causes toxic pneumonia or silicosis, and sometimes causes lung cancer. In addition, dust can contaminate buildings, exposing valuable ancient buildings to corrosion. Dust falling on the leaves of plants can hinder photosynthesis and inhibit growth. Productive dust is a natural enemy of human health and is a main cause of inducing various diseases. In the existing plastic processing, chemical production and food processing processes, the dust treatment cost is high, the treatment efficiency is low, the effect is poor, the dust overflows, the material utilization rate is low, and the existing processing and environmental control requirements are difficult to be met. Disclosure of utility model The utility model aims to solve the technical problem of providing a negative pressure feeding bin dust treatment system, which is convenient for controlling dust in the production and processing process of the prior art, avoids dust overflow, reduces environmental pollution and material waste, has high treatment efficiency, and ensures the cleanness of working environment and the efficient utilization of materials. In order to solve the technical problems, the scheme of the utility model is as follows: The utility model provides a feed bin dust processing system on negative pressure, includes the last feed bin that adopts sealed design, it has feed inlet and dust filtration unit to go up feed bin top intercommunication, and the bottom intercommunication has the discharge gate, dust filtration unit intercommunication has the unit of airing exhaust, the discharge gate bottom is provided with the blast air unit, still be provided with detecting element on the last feed bin, the unit of airing exhaust, blast air unit and detecting element have integrated control unit through signal transmission line intercommunication. The dust filtering unit comprises a dust collection bin and a negative pressure bin isolated by a filter plate. The filter plate comprises a filter layer made of filter element materials and porous protection filter plates arranged on two sides of the filter layer. The exhaust unit comprises an exhaust fan communicated with the dust collection bin and an exhaust pipe communicated with the exhaust fan. The air blast unit comprises an air inlet pipe arranged at the bottom end of the discharge hole and an air blower communicated with the air inlet pipe. The detection unit comprises a dust concentration sensor and a monitor. The feed inlet sealing connection has the inlet pipe. Compared with the prior art, the invention has the beneficial effects that: According to the application, due to the negative pressure, dust generated in the feeding bin can be sucked into the dust filtering unit, the dust is accumulated in the dust filtering unit, and gas is discharged through the exhaust unit communicated with the dust filtering unit, so that the pollution of the dust to the environment is reduced, and after materials come out from the discharge hole, the generated dust is blown into the feeding bin again through the blowing unit, so that the pollution of the dust to the environment is further reduced.
