Abstract
The utility model relates to the technical field of domestic garbage treatment, in particular to a return air mechanism of a garbage scattering machine; the air diffuser comprises a diffuser shell, an exhaust fan, a fan connecting pipe, an arc-shaped pipe and an exhaust pipe, wherein an air inlet of the exhaust fan is connected with the fan connecting pipe, the fan connecting pipe is connected with a first end of the arc-shaped pipe through a first flange, a second end of the arc-shaped pipe is connected with the exhaust pipe through a second flange, the exhaust fan is arranged in the middle of the diffuser shell, an air outlet of the exhaust fan is communicated with the interior of the diffuser shell, air close to a feeding end in the diffuser shell is extracted through the exhaust fan and injected into the middle section of the diffuser shell, and then the air flowing direction in the diffuser shell is changed into that a discharging end flows to the feeding end; the hot air in the shell of the scattering machine carries water vapor to flow from the discharge end to the feed end, so that the phenomenon that the discharge end of the scattering machine is wet due to temperature reduction is avoided, and the preheating effect can be generated on the garbage newly entering the feed end.
Description
Technical Field
The utility model belongs to the technical field of the domestic waste treatment technique and specifically relates to rubbish scattering machine return air mechanism.
Background
In the scattering process before garbage classification, hot air is blown into the scattering mechanism in order to improve scattering efficiency in part of processes, and the garbage is dried by utilizing the hot air, so that the garbage is more favorable for scattering. For example, chinese patent discloses a scattering and drying integrated machine for a waste incinerator, patent No. 201820896446.0, in which: the casing is a closed shell, and the casing includes inducer and export section, and the cross sectional area of export section is greater than the cross sectional area of inducer, and the tip of inducer is provided with the feed inlet, and the tip of export section is provided with the export, and the bottom of inducer is provided with hot-blast import, and the top of export section is provided with hot air outlet.
The technical scheme has the following defects: hot-blast entering can carry steam behind the casing, if let hot-blast and rubbish syntropy flow to export section, then steam also can flow to export section, because hot-blast temperature is the highest and has reduced to its temperature of export section when having certainly just got into, so steam probably because the reduction of hot-blast temperature recondenses into water again and adheres on rubbish, produces harmful effects to the work of breaing up.
Disclosure of Invention
To prior art's not enough, the utility model provides a machine return air mechanism is broken up to rubbish, it can be so that steam flows to the import section to make steam by used repeatedly as far as possible.
The technical scheme of the utility model is that:
garbage scattering machine return air mechanism, it is including scattering quick-witted casing, air exhauster, fan connecting pipe, arc pipe and exhaust tube, the air intake connection of air exhauster has the fan connecting pipe, the fan connecting pipe is through the first end of first flange joint arc pipe, the second end of arc pipe has the exhaust tube through second flange joint, the air outlet and the inside intercommunication of scattering quick-witted casing at the middle part of scattering quick-witted casing and air exhauster are installed to the air exhauster, the opening direction of placing at scattering quick-witted casing feed end and exhaust tube tip at the exhaust tube tip is the same with the feed direction of scattering quick-witted casing, prevents that rubbish from being sucked by a large amount of exhaust tubes.
In some embodiments, the fan connecting pipe, the arc pipe and the air suction pipe are all hot bends. The utility model discloses an in the structure for the convenience of the installation of return air mechanism, fan connecting pipe, arc pipe and exhaust tube all do not take place fixed connection with the quick-witted casing that breaks up, that is to say only rely on being connected of fan connecting pipe and air exhauster to realize the support atress of three pipe fitting spare. The hot-bent pipe has better ductility than the cold-bent pipe, and cracks are not easy to appear after mechanical vibration.
In some embodiments, the suction pipe is removably provided with a screen at an open end thereof to further prevent debris from being drawn into the suction fan from the suction pipe.
The utility model has the advantages that: extracting air close to the feeding end in the scattering machine shell through an exhaust fan and injecting the air into the middle section of the scattering machine shell, so that the flowing direction of the air in the scattering machine shell is changed into that the air flows from the discharging end to the feeding end; the hot air in the shell of the scattering machine carries water vapor to flow from the discharge end to the feed end, so that the phenomenon that the discharge end of the scattering machine is wet due to temperature reduction is avoided, and the preheating effect can be generated on the garbage newly entering the feed end.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure, 1, an exhaust fan; 2. a fan connecting pipe; 3. a first flange; 4. an arc tube; 5. a second flange; 6. an air exhaust pipe; 7. a breaker housing; 8. an air heater.
Detailed Description
The following description of the embodiments of the present invention will be made with reference to the accompanying drawings:
example 1
As shown in fig. 1, rubbish breaker return air mechanism, it includes breaker casing 7, air exhauster 1, fan connecting pipe 2, arc pipe 4 and exhaust tube 6, the air intake connection of air exhauster 1 has fan connecting pipe 2, fan connecting pipe 2 is through the first end of first flange 3 connection arc pipe 4, the second end of arc pipe 4 is connected with exhaust tube 6 through second flange 5, air exhauster 1 is installed at the middle part of breaker casing 7 and the air outlet of air exhauster 1 and the inside intercommunication of breaker casing 7, the opening direction that 6 tip of exhaust tube was placed at breaker casing 7 feed end and 6 tip of exhaust tube is the same with the feed direction of breaker casing 7, prevents that rubbish from being by a large amount of suctions of exhaust tube.
The fan connecting pipe 2, the arc-shaped pipe 4 and the exhaust pipe 5 are all hot bending elbows.
The quick-witted casing of breaing up and this machine casing of breaing up 7 that have adopted the drum formula in this embodiment have air heater 8 through the support mounting, but it should be pointed out that the mechanism all can adopt are broken up to arbitrary current pipeline formula rubbish that has the hot air drying function the utility model discloses the quick-witted return air mechanism of rubbish breaing up of record all can play the effect that improves drying efficiency, preheat rubbish.
Example 2
The suction tube open end detachably is provided with the filter screen, further prevents rubbish from being followed the suction tube and is drawn the air exhauster.
The other structure of this embodiment is the same as embodiment 1.
