Embodiment：

Shown in following Fig. 1 to Fig. 4, a kind of sludge digesting unit with agitating function includes organic frame 1 and is arranged on machine Cylindrical digestion bucket 2 on frame 1, digestion bucket 2 have liner 21 and the outer courage 22 being set in outside liner 21, liner 21 and outer courage 22 Between there is buffer channel 3, multiple through holes 4 connected with buffer channel 3 are provided on the side wall of liner 21, on buffer channel 3 The top of stirring hoisting mechanism 5 there are two setting, liner 21 and outer courage 22 is sealed by end cap 6, and the bottom of end cap 6 is laterally affixed There is the retainer ring 7 of annular, the inner peripheral surface of retainer ring 7 has internal tooth 8, rotatable active is provided on the center of circle of retainer ring 7 Gear 9, there are three driven gears 10, the external tooth of each driven gear 10 to be nibbled with the internal tooth 8 of retainer ring 7 for engagement on driving gear 9 It closes, is sequentially connected with rotation axis 11 on driven wheel, the end of rotation axis 11 extends close to the bottom of liner 21, along rotation axis 11 Length direction be arranged at intervals there are three rectangle blade 12, one end of blade 12 and the outer circumference surface of rotation axis 11 are affixed, leaf The other end of piece 12 is vertically connected with push plate 13, and the distance of push plate 13 to 21 inner peripheral surface of liner is 1-10 ㎜.

Stirring hoisting mechanism 5 includes rotating disk 51, connecting rod 52, sliding block 53 and agitating paddle 54, and rotating disk 51 is rotatable It is arranged on end cap 6, one end and the surface of rotating disk 51 of connecting rod 52 are affixed, and the other end straight line of connecting rod 52 prolongs through end cap 6 It extends in buffer channel 3 and is connected with sliding block 53, there are three rotatable agitating paddles 54 for the bottom setting of sliding block 53.Sliding block 53 arrives The distance of 22 side wall of liner 21 or outer courage is less than 1 ㎝.

Pending sludge, which is input in liner 21, makes it be filled up completely liner 21 (or lower part of liner 21), then While driving gear 9 rotates driven gear 10 is driven to be rotated on the external tooth of driving gear 9, retainer ring 7 can effectively ensure that The movement locus of driven gear 10 makes it be rotated always around driving gear 9, promotes rotation axis 11 with movable vane piece 12 and push plate 13 The rotation in liner 21, during rotation, push plate 13 can be persistently to one centrifugal force of sludge rotated at different position And thrust, sludge is promoted to do centrifugal movement so as to which it be squeezed away at through hole 4, after being extruded away, the dirt in liner 21 Mud volume reduces, and blade 12 can be sufficiently stirred for uniformly, and the sludge being extruded away is located in buffer channel 3, rotation Disk 51 drives the rotation of connecting rod 52 that connecting rod 52 is promoted to be moved up and down with movable slider 53 in buffer channel 3, and agitating paddle 54 rotates Sludge agitation in buffer channel 3 is uniform, and while agitating, agitating paddle 54 is one centrifugation of sludge in buffer channel 3 Power promotes it to do centrifugal movement, so as to being re-introduced by through hole 4 in liner 21, complete a liner 21 and outer courage 22 it Between sludge exchanging operation, blade 12 rotate during, the position of sludge can constantly change, so that being extruded Compared with last time it was different to the sludge in buffer channel 3, so as to which sludge agitation is obtained evenly；In addition, in sludge It when being filled up completely liner 21, is influenced by gravity, can be also extruded in buffer channel 3 positioned at the sludge by lower part.It will fill out The sludge for being charged into liner 21 is divided into two parts while stirs evenly it respectively automatically, and different sludge can be in liner 21 Exchange back and forth is carried out between outer courage 22, so as to accelerate the digestion rate of sludge, improves efficiency.

It is set on outer courage 22 there are two cylinder 14, the piston end of each cylinder 14 passes through side wall and the drive connection of outer courage 22 There is the feeding plate 15 of arc, feeding plate 15 is located in buffer channel 3, and the surface and the madial wall of outer courage 22 for feeding plate 15 are abutted against, Each feeding 15 head and the tail of plate pass sequentially through spring intervals and connect to form a feeding cavity concentric with liner 21 or outer courage 22.

After completing to stir operation, the sludge of a part can be remained in buffer channel 3, is made by the piston motion of cylinder 14 It feeds plate 15 constantly to move to 21 direction of liner, so that the sludge in buffer channel 3 is pushed through in liner 21, in movement During, the volume of the feeding cavity of feeding plate 15 formation of head and the tail connection can constantly reduce, in the process, by setting The spring between is put to recover its reset condition.

There is the pan feeding opening 16 connected with liner 21 on end cap 6.Device needs will carry out operation under anaerobic state, End cap 6 can effectively seal liner 21 and outer courage 22, and sludge is inputted by pan feeding opening 16 into liner 21, and vacuum Air in liner 21 can be evacuated by generator by pan feeding opening 16.

The sludge for being filled into liner 21 is divided into two parts and simultaneously stirs evenly it respectively by the present embodiment automatically, and not Same sludge can carry out exchange back and forth between liner 21 and outer courage 22, so as to accelerate the digestion rate of sludge, improve Efficiency.

Finally illustrate, above example is merely intended for describing the technical solutions of the present application, but not for limiting the present application, although ginseng The utility model is described in detail according to preferred embodiment, it will be understood by those of ordinary skill in the art that, it can be to this The technical solution of utility model is modified or replaced equivalently, should all without departing from the objective and scope of the technical program Cover among the right of the utility model.
