Description
Technical field
The present invention is mainly concerned with the environmental protection equipment field, refers in particular to a kind of mainly being applicable to house refuse is carried out the pretreated discharging mechanism of scale and had the rubbish pretreatment unit of this discharging mechanism.
Background technology
Along with the quick propelling of Urbanization Progress, domestic waste increases sharply, and garbage disposal ability relative deficiency has been the difficulty that the city faces.People are in line with the principle of suiting measures to local conditions, and progressively and select safe and reliable, advanced environmental protection, land saving energy saving, economic and practical technology of garbage disposal, basically form the ability to be harmless that is complementary with Output of Domestic Waste with expectation.Such as published Chinese patent application: a kind of devices and methods therefor for scale pretreatment house refuse (publication number 102626710A); wherein disclosed technical scheme has just realized the removal of organic matter of rubbish and the reduction of water ratio, garbage drying successful well.This device has the advantages such as simple and compact for structure, that floor area is little, can realize the pretreated scale of house refuse, industrialization, through engineering approaches and continuous Detroit automation.This device mainly is applicable to scale pretreatment house refuse; but from technical standpoint; be in the material that rubbish in the vertical type fermentation storehouse belongs to large volume, large quality, high pressure; and when being in again in the vertical type fermentation storehouse that has quite height, so how to realize smooth and continuous discharge just seems particularly important.
In published technical scheme, the rubbish pretreatment unit intends taking traditional spiral discharging mode, but spiral discharge device mainly is to be applicable to rickle body, little quality, the little material situation of pressure, its situation that is applied to large volume, large quality, high pressure to have larger difficulty.By long-term practical studies, find that its reason just is:
1, the dump cognition of large volume, large quality, high pressure all falls within on the spiral discharge device, this moment, spiral discharge device need to be born huge weight (pressure) power of junk-heap body, and spiral discharge device often is difficult to its top rubbish of effective support, the simultaneously running of whole spiral discharge device needs huge bearing to support, and causes whole volume, taking up room becomes huge.
2, junk-heap body all falls within on the spiral discharge device, when spiral discharge device is wanted normal operation, just must overcome huge force of sliding friction and force of rolling friction, according to friction force computing formula f=μ N, rubbish friction coefficient after sinking in fact is between 0.5～0.8, and the rubbish of tens of tons of weight will produce tens of tons slip and force of rolling friction.Like this, on the one hand just require spiral discharge device that enough Rigidity and strengths need to be arranged, also need on the other hand dynamic enough powerful actuating devices simultaneously, normally the carrying out of guarantee bolt discharging.
3, whole rubbish pretreatment unit is in for a long time and does not shut down mode of operation, to guarantee the continuity of garbage disposal.So, spiral discharge device just will be in for a long time huge normal stress, huge force of sliding friction and the synergy of force of rolling friction and turn round, cause the bolt drawing mechanism very easily to deform, greatly reduce service life, it overhauled will become a kind of normality.
4, to guarantee effective running of spiral discharge device; the bearing of spiral discharge device, support helix drawing mechanism and actuating device all must have enough strength and stiffness; the specification of these devices all will be huge; this just needs the huge material usage of cost and the huge drive energy of cost; cost of manufacture, operating cost are all very high, are difficult to carry out large-scale promotion and use.
Other has the practitioner to propose a kind of drum-type garbage drawing mechanism, and for example Chinese patent ZL200620060370.5 namely discloses the drawing mechanism that a kind of usefulness solves Multi-layer panel-turnover refuse disposal system discharging problem.But for being in the large volume in the vertical type fermentation storehouse that has quite highly, large quality, high pressure material, it can't reach better result of use equally.Although the cylinder rotating manner that it adopts has lacked force of sliding friction than the spiral discharging mode, the problem that still exists above-mentioned spiral discharge device to run into.The deficiency of this drum-type drawing mechanism just is:
1, junk-heap body all falls within on the cylinder drawing mechanism, roller device will turn round, and must overcome huge force of rolling friction, according to friction force computing formula f=μ N, rubbish friction coefficient after sinking in fact is between 0.5～0.8, and the rubbish of tens of tons of weight will produce tens of tons force of rolling friction.This just requires the cylinder drawing mechanism that enough rigidity, intensity are arranged on the one hand, requires simultaneously on the other hand it to have enough powerful actuating device.
2, the long-term assurance of cylinder drawing mechanism effectively turned round; the bearing of cylinder drawing mechanism, back-up roller drawing mechanism and actuating device all must have enough strength and stiffness; the specification of these devices all will be huge so; need the huge material usage of cost and the huge drive energy of cost; cost of manufacture, operating cost are all very high, finally are difficult to realize the large-scale promotion application.
3, cylinder seals than the more disadvantageous cylinder that is of spiral, and cylinder itself will support whole garbage weights, is not easy to connect stiffener in the cylinder space, so that cylinder wall is very thick, waste of material is larger than spiral, more is not easy to maximization, through engineering approaches.
4, from principle of design, the drum-type drawing mechanism is according to the principle design discharge method of rubbish self-supporting, but after taking to rotate with rubbish " strand " mode out by force.
