Description
Technical field
The utility model relates to the sedimentation conveying devices in a kind of sludge anhydration burning technique, belong to sludge drying technique neck
Domain.
Background technique
Sludge, screenings and the sludge of sewage treatment plant that paper mill generates contain a large amount of fibers, and calorific value is higher, by sludge
It can be used as fuel combustion after drying and other treatment, accomplish townm refuse and other solid waste reducings, recycling, harmless treatment
And comprehensive utilization, meet national industrial policies.In mud drying process, moisture content is reduced to from 65% after sludge drying
35%, the screenings of sludge and moisture content 35% or so after desiccation mixes boiler burning together, realizes solid waste comprehensive utilization of resources.
The exhaust gas generated in the process needs to handle by scrubbing tower, after the waste water containing shale that scrubbing tower generates enters settling tank sedimentation
Return to wet feed storehouse (i.e. the apparatus for feeding of sludge drying system).Conveying equipment on existing settling tank, after installation and operation, Chang Yin
It settles bottom of pond portion feed back to overstock, causes conveying equipment overcurrent that can not start.
Utility model content
According to the above-mentioned deficiencies in the prior art, technical problem to be solved by the utility model is: to provide a kind of sludge dry
Change the sedimentation conveying device in burning process, to solve the above problems.
Sedimentation conveying device in sludge anhydration burning technique described in the utility model, including shell, lower part of the housing be in
Back taper, lower part of the housing are connected to transfer passage, conveying device are equipped in transfer passage, and conveying device is placed in enclosure interior；Shell
Bottom is equipped with compressed air pipe, and compressed air pipe is communicated with enclosure interior.
The dust in conveying device recycling scrubber generation flue dust is settled, dust reaches enclosure interior together with waste water, in weight
Start to be layered under the action of power, sludge is gradually deposited to bottom, and the sludge of bottom reaches wet feed storehouse (i.e. sludge by conveying device
The apparatus for feeding of anhydration system), reenter sludge drying system.In the process, compressed air passes through compressed air pipe
Enclosure interior is entered, material can be made to stir, prevents bottom feed back from overstocking, avoids conveying device overcurrent that from can not starting.
The housing bottom is equipped with rotation cleaner, prevents bottom when clear tank from blocking, and rotation block clearing motor spindle is set
There is bottom cover.
The compressed air pipe includes that the compressed air of annular is responsible for and several compressed air branch pipes, several compressions skies
Gas branch pipe is uniformly distributed along lower part of the housing.
The conveying device is drag conveyor.
The case top is equipped with negative pressure ventilation pipe, the steam heat generated in recycling sedimentation conveying device to washing
Tower.
The housing side is equipped with feed inlet, and the waste water containing shale from scrubbing tower enters in shell from feed inlet.
In housing side, the position lower than feed inlet is equipped with overflow port, avoids liquid level in shell excessively high.
In housing side, the position lower than overflow port is equipped with water return outlet, and the water on upper layer returns to washing by water pump after sedimentation
Tower reduces the consumption of water resource as shower water.
Possessed beneficial effect is the utility model compared with prior art:
Sedimentation conveying device in sludge anhydration burning technique described in the utility model, reasonable in design, compressed air
Enclosure interior is entered by compressed air pipe, material stock in shell is fluidized, prevents bottom feed back from overstocking, avoids conveying
Device overcurrent can not start, and thoroughly solve the problems, such as that conveying device overcurrent can not start.In mud drying process, generation is given up
Expect (dust, waste water etc.), is recycled to equipment or scrubbing tower again, is recycled or handled.Transfer passage is communicated with shell,
Using closed conveying mode, stench uncontrollable discharge is controlled.
