Abstract
The utility model relates to a sludge recycling device and in particular relates to a sludge drying device. The sludge drying device comprises a shell, a motor and a middle shaft provided with spiral blades, the middle shaft is connected with the output shaft of the motor, the two ends of the middle shaft are respectively fixed on the shell, a sludge feeding hole and a sludge discharging hole are respectively formed at the two ends of the shell, a steam outlet is also formed on the shell, a spiral thermal medium pipeline is arranged between the shell and the middle shaft, and the two ends of the thermal medium pipeline are respectively communicated with a thermal medium inlet and a thermal medium outlet formed at the two ends of the shell. The sludge drying device provided by the utility model has the beneficial effects that the spiral thermal medium pipeline is adopted for drying sludge stirred and rotated by the middle shaft provided with the spiral blades, so that the contact area is increased, and the drying effect is enhanced; and thermal medium is also injected into the cavities in the middle shaft and the spiral blade, so that the drying effect is better.
Description
Technical field
The utility model relates to the recycle device of mud, refers in particular to a kind of sludge drying mechanism.
Background technology
The problem of a large amount of sludge treatment difficulties that sewage disposal at present produces is very general, most sewage works just are sent to the refuse tip landfill with mud or are directly exposed in the wilderness, this sludge moisture content height, perishable, strong stink is arranged, and contain parasitic ovum, pathogenic micro-organism and heavy metal, as not dealt carefully with, discharging will cause secondary pollution arbitrarily.
Many covers sludge treatment method of taking both at home and abroad at present: have plenty of mud is refertilized in the farmland through thermal purification (heating or compost) or chemical purification (using unslaked lime); Mud dries in the elder generation that has, and is applying fertilizer in the farmland then; Burn the back that mud is dried that has.But still there is the risk of secondary pollution in mud in the process of drying.Mud is deposited in and gives out foul smell and peculiar smell in the open, and Exposure to Sunlight wind blows, and contaminant particle can cause topsoil; Through water logging bubble, dissolving, pollutent follows sewage to flow into the river course, can polluted surface water, and not only cause visual pollution, and provide the place for growing of other harmful organisms.
Summary of the invention
For overcoming the above problems, it is a kind of simple in structure that the utility model provides, and avoids the risk of secondary pollution, and the better sludge drying mechanism of drying effect.
Sludge drying mechanism, comprise housing, motor and have the axis of screw-blade, in take out with the output shaft of motor and be connected, the axis two ends are separately fixed on the housing, the housing two ends are respectively equipped with sludge inlet and mud discharge port, also be provided with vapour outlet on the housing, be provided with the hot medium pipeline of spiral between housing and the axis, the hot medium pipeline two ends are communicated with the thermal medium entrance that is located at the housing two ends and thermal medium outlet respectively.
As a kind of improvement of the present utility model, be provided with cavity in described axis and the screw-blade, and axis is communicated with all with the cavity of screw-blade, the axis two ends are communicated with thermal medium entrance and thermal medium outlet respectively.
The beneficial effects of the utility model are: the utility model adopts the hot medium pipeline of spiral that the mud that is stirred rotation by the axis that has screw-blade is carried out drying, has increased contact area, increases drying effect; Cavity in axis and the screw-blade is also injected thermal medium, and drying effect is better.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
By reference to the accompanying drawings 1, a kind of sludge drying mechanism, comprise that housing 1, motor (are located at enclosure interior, accompanying drawing does not mark) and have the axis 2 of screw-blade 3, in take out with the output shaft of motor 5 and be connected, axis 2 two ends are separately fixed on the housing 1, housing 1 two ends are respectively equipped with sludge inlet 1-3 and mud discharge port 1-5, also be provided with vapour outlet 1-2 on the housing 1, be provided with the hot medium pipeline 4 of spiral between housing 1 and the axis 2, hot medium pipeline 4 two ends are communicated with the thermal medium entrance 1-1 that is located at housing 1 two ends and thermal medium outlet 1-2 respectively.
In addition, also can be provided with cavity in axis 2 and screw-blade 3, and axis 2 is communicated with all with the cavity of screw-blade 3, axis 2 two ends are communicated with thermal medium entrance 1-1 and thermal medium outlet 1-4 respectively.
Mud enters housing 1 from sludge inlet 1-3, and driven by motor axis 2 and screw-blade 3 rotations feed thermal medium in the hot medium pipeline 4, simultaneously as oil, steam etc.Mud is centrifugal rotation under agitation, repeatedly contacts hot medium pipeline 4 and carries out drying, and dried mud is discharged from mud discharge port 1-5, and the steam that produces in the drying process is got rid of from vapour outlet 1-2.
Claims (2)
1. sludge drying mechanism, comprise housing, motor and have the axis of screw-blade, in take out with the output shaft of motor and be connected, the axis two ends are separately fixed on the housing, the housing two ends are respectively equipped with sludge inlet and mud discharge port, also be provided with vapour outlet on the housing, it is characterized in that: be provided with the hot medium pipeline of spiral between housing and the axis, the hot medium pipeline two ends are communicated with the thermal medium entrance that is located at the housing two ends and thermal medium outlet respectively.
2. sludge drying mechanism according to claim 1 is characterized in that: be provided with cavity in described axis and the screw-blade, and axis is communicated with all with the cavity of screw-blade, the axis two ends are communicated with thermal medium entrance and thermal medium outlet respectively.
