Specific embodiment
The present invention will be further explained below with reference to the attached drawings:
As shown in Figure 1-3, a kind of anaerobic fermentation of kitchen waste removes dross device, comprising:
Shell 1, shell 1 is the tubular structure of both ends open, and one end is flat segments 101, and the other end is that diameter is gradually smaller
The end of conical section 102, flat segments 101 and conical section 102 is respectively outlet end and slag output end, is distinguished on outlet end and slag output end
Equipped with first end cover 7 and second end cover 13.Shell 1 is equipped with inlet 103 close to the outer wall of outlet end, and shell 1 is fixed on branch
On frame 2.
Rotary drum filter cylinder 3, the closed at one end of rotary drum filter cylinder 3, the other end are opening, and rotary drum filter cylinder 3 is located in shell 1 and it is spacious
Mouthful the outlet end of one end corresponding housing 1, closed one end corresponding housing 1 slag output end, the structure and shell 1 of rotary drum filter cylinder 3
It is corresponding, it is also classified into flat structure and cone-shaped structure, the gap between rotary drum filter cylinder 3 and shell 1 forms dross disengagement chamber
10, filter hole 5 is laid on the cylinder of 3 flat segments 101 of rotary drum filter cylinder.Outlet tube 4 is connected on the open end of rotary drum filter cylinder 3,
And outlet tube 4 is pierced by by first end cover 7 and stretches out in the outer wall of 1 outer drum filter cylinder 3 of shell equipped with helical blade 11, helical blade
There are certain interval between 11 and shell 1, helical blade 11 is gradually become from the open end of rotary drum filter cylinder 3 to closing extreme direction screw pitch
It is small.In addition, the outer surface of rotary drum filter cylinder 3 is coated with filter screen 6, it is connected with rotary joint 8 on the outlet tube 4 of rotary drum filter cylinder 3, revolves
Drain pipe 14 is connected on adapter 8.
Seal bracket 12 of slagging tap including annular, the inner ring for seal bracket 12 of slagging tap, which is equipped with, facilitates being serrated for deslagging
The mud hole 1201 of gap, the seal bracket 12 of slagging tap are installed on the slag output end of shell 3 and outer with 3 closed end of rotary drum filter cylinder
There is certain interval (such as Fig. 2) between week, seal bracket 12 of slagging tap passes through 13 axial restraint of second end cover.
Transmission device, transmission device include belt wheel 9, belt (not shown) and motor (not shown), belt wheel 9 with
Outlet tube 4 is fixedly connected, and belt wheel 9 is connected to the motor by belt to be connect, and motor can drive rotary drum filter cylinder 3 and helical blade 11 together
Rotation.
Working principle of the present invention is as follows:
When anaerobic reaction system works, its exterior is equipped with fluid circulation system, fluid circulation system will be in anaerobic reaction fermentor
Supernatant constantly imported into the bottom of fermentor and be generally mingled in derived supernatant for accelerating fermentation process
Dross.
When anaerobic fermentation of kitchen waste of the present invention is arranged except dross device, the outlet pipe of fluid circulation system is connected this
The inlet 103 of invention, the water inlet pipe of fluid circulation system connect drain pipe 14 of the invention, are then turned on motor, and motor drives
Rotary drum filter cylinder 3 and helical blade 11 rotate together, because being connected with rotary joint 8 between drain pipe 14 and outlet tube 4, row
Liquid pipe 14 is fixed.When work, the liquid of supernatant is entered in dross disengagement chamber 10 by inlet 103, is pressed from both sides in liquid
Miscellaneous dross rests in dross disengagement chamber 10, liquid then passes through filter screen 6 and mistake because of the blocking of filter hole 5 and filter screen 6
Filter opening 6 enters in rotary drum filter cylinder 3, is then entered in the water inlet pipe of fluid circulation system by outlet tube 4 and drain pipe 14.Liquid
Then it is flowed into rotary drum filter cylinder 3 in flow process by filter hole 5.
Dross in dross disengagement chamber 10 is slowly moved to 1201 direction of mud hole along helical blade 11, because of helical-blade
Piece 11 gradually becomes smaller to the screw pitch in 1201 direction of mud hole, therefore dross is gradually compressed during being moved to, and can squeeze
Moisture in dross out, the more dry dross of discharge.Dross is moved to slag tap seal bracket 12 before, the dross accumulated below
Gradually released from the mud hole 1201 for slagging tap seal bracket 12.
It should be noted that the above is only the preferred embodiment of the present invention, it is noted that for the general of the art
For logical technical staff, without departing from the technical principles of the invention, several improvement and replacement can also be made, these change
It also should be regarded as into replacement to protection scope of the present invention.
