Description
Technical field
The utility model is related 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 generated, it, will if handled not in time
Secondary pollution is caused, moisture percentage in sewage sludge is very high, and conveying, processing or disposition are all inconvenient, needs to carry out thickening to sludge.Turn
Drum thickener is that flocculant is added in sewage, and then sewage is discharged into sieve, and the supernatant in sewage is leaked out from sieve,
Floc sedimentation constantly rolls forward, while volume is also gradually gathered and becomes larger with the rotation of sieve, finally discharges, realizes in sieve end
The separation of sludge and supernatant.Sieve can bond the solid matters such as sludge, therefore sieve one or both sides during rotation
It needs to install additional and rinses flooding nozzle, in time rinse out the condensation sludge on sieve, just can guarantee that sieve works normally.It is existing
It is axially evenly distributed along sieve 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.
Utility model content
For the above-mentioned prior art the problem of, the utility model, which provides one kind, can significantly improve supernatant recycling
The novel barrate thickener of rate and mud volume.
To achieve the above object, the utility model provides following technical solution：
A kind of novel barrate thickener passes through import including premixing tank, shell, rotary drum mechanism and flooding nozzle, premixing tank
Pipe and rotary drum mechanism connection, rotary drum mechanism and shell are rotatablely connected, and are equipped with flooding nozzle on the inside of shell, and flooding nozzle is along rotary drum
Mechanism axial alignment, outer casing bottom are equipped with liquid outlet, and casing ends are equipped with mud mouth, and flooding nozzle is arranged along the direction that sludge flows
From sparse to dense, rotary drum mechanism includes sieve and stent to row.
Further, flooding nozzle is 1 in first half and latter half the distribution number ratio of sieve：2.
Further, the horizontal position of flooding nozzle is higher than sieve central axes.
Further, inlet tube is equipped with bending close to sieve end, and bending angle is 90-135 °.
Further, outer casing bottom is obliquely installed.
The beneficial effects of the utility model are as follows：
1. increasing premixing tank, flocculant and pending sewage first in premixing tank are thoroughly mixed uniformly, increased
Reaction time makes the macromolecular substances in pending sewage form big floc sedimentation, improves the supernatant rate of recovery；
2. inlet tube sets 90-135 ° of bending angle, reduce impact of the sewage to sieve, extend the service life of sieve,
Newly formed unstable floc sedimentation is avoided to be broken up simultaneously；
3. rinsing arrangement mode close after being dredged before flooding nozzle is set as, the water consumption of sieve 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.
Description of the drawings
Fig. 1 is the overall structure diagram of the utility model；
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,

Specific embodiment
In order to which those skilled in the art is made to more fully understand the technical solution of the utility model, with reference to the utility model
Attached drawing carries out the technical solution of the utility model clear, complete description, and based on the embodiment in the application, this field is general
Other similar embodiments that logical technical staff is obtained under the premise of creative work is not made, should all belong to the application
The range of 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
Sieve 31 and stent, stent support sieve 31 are included, 1 bottom of premixing tank 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 equipped with close to 31 end of sieve
Bending, bending angle are 90-135 °, and inlet tube 11 sets 90-135 ° of bending angle, reduce impact of the sewage to sieve 31, prolong
The service life of long sieve 31, while newly formed unstable floc sedimentation is avoided to be broken up.Rotary drum mechanism 3 is rotatablely connected with shell 2,
2 inside of shell is equipped with flooding nozzle 4, and flooding nozzle 4 is higher than along 3 axial alignment of rotary drum mechanism, the horizontal position of flooding nozzle 4
31 central axes of sieve.2 lower tilt of shell is set, and convenient for collecting the supernatant to drip from sieve 31,2 bottom of shell is equipped with out liquid
Mouth 21,1 end of shell are equipped with mud mouth 22.Flooding nozzle 4 arranges from sparse to dense along the direction that sludge flows, and flooding nozzle 4 exists
First half and latter half the distribution number ratio of sieve 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, sieve first half 15, latter half 25.
Rotary drum mechanism 3 further includes shaft 33 and stent 32, and shaft 33 is connected with variable-frequency motor, and sieve 31 is solid by stent 32 and shaft 33
Fixed connection.Increase premixing tank 1, flocculant and pending sewage are first thoroughly mixed uniformly in premixing tank 1, increase anti-
Between seasonable, the macromolecular substances in pending sewage is made to form big floc sedimentation, improve the supernatant rate of recovery.
When thickener works, pending sewage is first evacuated to water pump in premixing tank 1, is then added in into premixing tank 1
Sewage is discharged into from inlet tube 11 in sieve 31 by flocculant, stirring after a certain period of time, and under the drive of variable-frequency motor, sieve 31 is not
Disconnected to rotate, the liquid in sewage is leaked down by sieve 31, and the macromolecular substances in sewage form floc sedimentation under the action of flocculant,
Floc sedimentation rolls forward with the rotation of sieve 31 forms the walk of bigger in rolling process, is finally arranged in the end of sieve 31
Go out, fall at mud mouth 22.Floc sedimentation is during advance is rolled, it is possible to be bonded on sieve 31, it is therefore desirable to sieve
Flooding nozzle 4 is rinsed in at least side setting of net 31, rinses the adhesive on sieve 31.Present inventor's discovery, sieve 31
First half adhesive is less, and latter half adhesive significantly increases.Therefore, inventor is weighed flooding nozzle 4 is rinsed
New arrangement forms by dredging close arrangement, on the one hand improves the flush efficiency of flooding nozzle 4, on the other hand, reduce sieve
The washing water quantity of 31 front ends avoids newly formed unstable floc sedimentation from being broken up.
