Description
Technical field
The present invention relates to sludge treatment device technical field, in particular to a kind of novel barrate thickener.
Background technology
During town domestic sewage and Industrial Waste Water Treatments, many sludge can be produced, will if handled not in time
Secondary pollution is caused, moisture percentage in sewage sludge is very high, and conveying, processing or disposal are all inconvenient, it is necessary to carry out thickening to sludge.Turn
Drum thickener is that flocculant is added in sewage, and then sewage is discharged into screen cloth, and the supernatant in sewage is spilt from screen cloth,
Floc sedimentation constantly rolls forward with the rotation of screen cloth, while also gradually collection fusion is big for volume, finally discharges, realizes in screen cloth end
The separation of sludge and supernatant.Screen cloth can bond the solid matters such as sludge, therefore screen cloth one or both sides during rotation
Need to install additional and rinse flooding nozzle, the condensation sludge on screen cloth is rinsed out in time, just can guarantee that screen cloth normal work.It is existing
It is axially evenly distributed along screen cloth that drum concentration machine, which rinses flooding nozzle,.The supernatant rate of recovery of existing drum concentration machine is only capable of reaching
To 50%, thickening efficiency is low, and mud extraction rate is uncontrollable.
The content of the invention
For above-mentioned problems of the prior art, the present invention provide one kind can significantly improve the supernatant rate of recovery and
The novel barrate thickener of mud volume.
To achieve the above object, the present invention provides following technical scheme：
A kind of novel barrate thickener, including premixing tank, shell, rotary drum mechanism and flooding nozzle, premixing tank pass through import
Pipe and rotary drum mechanism connection, rotary drum mechanism and shell are rotatablely connected, and are provided with flooding nozzle on the inside of shell, and flooding nozzle is along rotary drum
Mechanism axially arranges, and outer casing bottom is provided with liquid outlet, and casing ends are provided with mud mouth, and the direction that flooding nozzle flows along sludge is arranged
From sparse to dense, rotary drum mechanism includes screen cloth and support to row.
Further, flooding nozzle is 1 in first half and latter half the distribution number ratio of screen cloth：2.
Further, the horizontal level of flooding nozzle is higher than screen cloth axis.
Further, inlet tube is provided with bending close to screen cloth end, and bending angle is 90-135 °.
Further, outer casing bottom is obliquely installed.
Beneficial effects of the present invention are as follows：
1. increasing premixing tank, flocculant and pending sewage are first thoroughly mixed uniformly in premixing tank, increase
In the reaction time, the macromolecular substances in pending sewage is formed big floc sedimentation, improve the supernatant rate of recovery；
2. inlet tube sets 90-135 ° of bending angle, reduce impact of the sewage to screen cloth, extend the service life of screen cloth,
Newly formed unstable floc sedimentation is avoided to be broken up simultaneously；
3. rinsing before flooding nozzle is arranged to arrangement mode close after dredging, the water consumption of screen cloth leading portion is saved, is improved simultaneously
Rinse the flush efficiency of flooding nozzle；
4. the motor of drum concentration machine uses variable-frequency motor, by controlling the rotating speed of rotary drum, mud extraction concentration is adjusted.
Brief description of the drawings
Fig. 1 is the overall structure diagram of the present invention；
Fig. 2 is along A-A faces cross-sectional view in Fig. 1.
In figure：1-premixing tank, 11-inlet tube, 2-shell, 21-liquid outlet, 22-mud mouth, 3-rotary drum mechanism,
31-screen cloth, 32-support, 33-rotating shaft, 4-flooding nozzle.
Embodiment
In order that those skilled in the art more fully understand technical scheme, it is right with reference to the accompanying drawing of the present invention
Technical scheme carries out clear, complete description, and based on the embodiment in the application, those of ordinary skill in the art exist
The other similar embodiments obtained on the premise of not making creative work, it should all belong to the scope of the application protection.
Embodiment one：
A kind of novel barrate thickener, including premixing tank 1, shell 2, rotary drum mechanism 3 and flooding nozzle 4, rotary drum mechanism 3 is wrapped
Screen cloth 31 and support, support support screen cloth 31 are included, the bottom of premixing tank 1 is fixedly connected with inlet tube 11, the other end of inlet tube 11
Inside rotary drum mechanism 3, premixing tank 1 is connected by inlet tube 11 with rotary drum mechanism 3, and inlet tube 11 is provided with close to the end of screen cloth 31
Bending, bending angle are 90-135 °, and inlet tube 11 sets 90-135 ° of bending angle, reduce impact of the sewage to screen cloth 31, prolong
The service life of long screen cloth 31, while avoid newly formed unstable floc sedimentation from being broken up.Rotary drum mechanism 3 is rotatablely connected with shell 2,
The inner side of shell 2 is provided with flooding nozzle 4, and flooding nozzle 4 axially arranges along rotary drum mechanism 3, and the horizontal level of flooding nozzle 4 is higher than
The axis of screen cloth 31.The lower tilt of shell 2 is set, and is easy to collect the supernatant to drip from screen cloth 31, the bottom of shell 2 is provided with out liquid
Mouth 21, the end of shell 1 is provided with mud mouth 22.The direction that flooding nozzle 4 flows along sludge arranges from sparse to dense, and flooding nozzle 4 exists
First half and latter half the distribution number ratio of screen cloth 31 are 1：2, the gap between adjacent flooding nozzle 4 is flowed along sludge
Direction be gradually reduced, in the present embodiment, flooding nozzle 4 sets 40 altogether, screen cloth first half 15, latter half 25.
Rotary drum mechanism 3 also includes rotating shaft 33 and support 32, and rotating shaft 33 is connected with variable-frequency motor, and screen cloth 31 is solid by support 32 and rotating shaft 33
Fixed connection.Increase premixing tank 1, flocculant and pending sewage are first thoroughly mixed uniformly in premixing tank 1, increase is anti-
Between seasonable, the macromolecular substances in pending sewage is formed big floc sedimentation, improve the supernatant rate of recovery.
When thickener works, pending sewage is first evacuated in premixing tank 1 with water pump, is then added into premixing tank 1
Flocculant, sewage is discharged into screen cloth 31 from inlet tube 11 after stirring certain time, under the drive of variable-frequency motor, screen cloth 31 is not
Disconnected to rotate, the liquid in sewage is leaked down by screen cloth 31, and the macromolecular substances in sewage form floc sedimentation in the presence of flocculant,
Floc sedimentation rolls forward with the rotation of screen cloth 31, bigger walk is formed in rolling process, finally arranged in the end of screen cloth 31
Go out, fall at mud mouth 22.Floc sedimentation is during advance is rolled, it is possible to is bonded on screen cloth 31, it is therefore desirable to sieving
At least side of net 31, which is set, rinses flooding nozzle 4, the adhesive rinsed on screen cloth 31.Present inventor's discovery, screen cloth 31
First half adhesive is less, and latter half adhesive substantially increases.Therefore, inventor is weighed flooding nozzle 4 is rinsed
New arrangement, formed by dredging close arrangement, on the one hand improve the flush efficiency of flooding nozzle 4, on the other hand, reduce screen cloth
The washing water quantity of 31 front ends, newly formed unstable floc sedimentation is avoided to be broken up.
