Description

Depositing dust accumulator conveyer
Technical field
The utility model relates to a kind of device for transporting objects, particularly a kind of depositing dust accumulator conveyer; The depositing dust that it the is suitable for granular material conveying of gathering materials, belongs to material pipe sealing transportation art.
Background technology
It is an industry difficult problem, the particularly depositing dust technology of gathering materials that granular material is carried always.
Granular material is carried and is adopted manual work at present, and production scene dust is many, and circumstance is poor, and labour intensity is high, easily suffers from occupational disease.These several years, along with the shortage of labour power, cost of labor constantly rose, and problem workman's health being damaged due to working environment can not be ignored.In addition, material, through easily stopping up in pipe conveying procedure, therefore can produce high-decibel harsh noise again and again, causes pollution from environmental noise.
Utility model content
In order to solve the above-mentioned problems in the prior art, the utility model proposes a kind of depositing dust accumulator conveyer, it can carry transfer to material under sealed environment, not only can reduce greatly the dust of production scene, and can reduce operating noise, thereby improve employee's working environment.
The purpose of this utility model is achieved by the following technical programs:
A kind of depositing dust accumulator conveyer, it comprises aggregate bin body, feeding-passage, air draft passage, discharge channel, free air diffuser, filtering net and dust-separation sleeve; Described filtering net and dust-separation sleeve are installed in aggregate bin body body from top to bottom successively, in intercepting granular material, and energy allowing air flow; Described feeding-passage be connected with the inlet point of being located at aggregate bin body sidewall and the position of inlet point lower than the installation site of dust-separation sleeve, in feeding-passage, be provided with the inlet valve opening and closing for controlling this passage, material enters aggregate bin body interior by inlet valve from inlet point; Described air draft passage is connected with the suction opeing of being located at aggregate bin bodies top, and in air draft passage, be provided with the exhausting valve opening and closing for controlling this passage, make aggregate bin body interior be the negative pressure state that approaches vacuum, material enters aggregate bin body interior under gas pressure; Described discharge channel is connected with the discharge port of being located at aggregate bin body bottom, is provided with the discharge valve opening and closing for controlling this passage in discharge channel, and material is discharged from discharge port by discharge valve; Described free air diffuser be connected with the admission port of being located at aggregate bin body sidewall and the position of admission port higher than the installation site of filtering net, in free air diffuser, be provided with the air inlet valve opening and closing for controlling this passage.
In addition, the utility model technique scheme is also further improved as follows:
The entrance of described feeding-passage is connected with the open feeder hopper that opening increases, and the inwall of aggregate bin body is provided with the corresponding feed position detecting device of height and position with inlet point.
The outlet of described air draft passage is connected with roots blower or for other air extractors of extracting air.
The inwall bottom of described aggregate bin body is provided with the height and position of discharge port unloads material-level detecting device accordingly.
Described dust-separation sleeve descends greatly the sleeve wall that bore is little and the screen cloth being installed in sleeve wall lower port to form by upper bore.
The utility model method of operation is as follows:
First close air inlet valve and discharge valve, open inlet valve and exhausting valve.Start roots blower, make aggregate bin inside approach vacuum and produce negative pressure, material is fed passage and sucks in aggregate bin body, under the iris action of dust-separation sleeve, material particles declines along aggregate bin inner body wall spiral fashion in aggregate bin body, in dropping process, granular material is broken up, is separated with dust-like material, because dust-like material is lighter, the rising air draught air-flow of roots blower can enter dust-separation sleeve and blow to filtering net with part dust-like material, relatively heavier granular material continues to fall, and is piled up in the bottom of aggregate bin body.When material sucks a certain amount of, when the material of piling up rises to the position at feed position detecting device place, close exhausting valve, inlet valve, roots blower is quit work, open discharge valve, material is discharged from discharge port through discharge valve, after material is all unsnatched, discharge valve cuts out automatically, completes work at present circulation.
Due in working cycle before, particulate species material and most granular material fall under gravity into aggregate bin body bottom, but, because the larger air-flow of dustiness is from the close together of filtering net, part dust-like material is adsorbed to filtering net surface, cause airflow not smooth, make the permeability to air of filtering net greatly reduce and produce resistance, in passage, be prone to local latch up phenomenon, particularly when high velocity air is by narrow and small gap, can produce ear-piercing howling, so, need to clear up the dust-like material on filtering net.Therefore, when completing after several working cycle, can close inlet valve and exhausting valve, open air inlet valve and discharge valve, outside blower fan is blown to aggregate bin body interior by free air diffuser, under gas pressure, the dust-like material being adsorbed on filtering net is blown off, and discharges from discharge port by dust-separation sleeve and discharge channel.
The utility model compared with prior art, has the following advantages and effect:
1) when the utility model uses, can greatly reduce the dust of production scene, improve circumstance;
2) when the utility model uses, can be good at solving in granular material seal for pipe joints course of conveying and hold a susceptible to plugging difficult problem;
3) production efficiency is high, and workman is freed and reduced cost of human resources from onerous toil;
4) adopt open feeder hopper, in fill process, not only facilitate material transferring, and can also avoid producing material transmit way in produce dust;
5) machine working stability, operating noise is low.
6) material-level detecting device can obtain the state of material in container automatically, and to realize the automation control of monitoring material position and system, the error of avoiding manual detection to cause, realizes safety in production.
7) dust-separation sleeve can make air draught air-flow velocity accelerate, intensity strengthen and air-flow accelerate after, partly plastic particle is offset thereupon, strikes sleeve wall and is rebounded downwards, has improved collision frequency, ensure absorption dust shake from plastic grain, raising separating effect.
