TECHNICAL FIELD

[0001] The present application relates to the technical field of sludge treatment, in particular to a drying incineration equipment for municipal sludge treatment. BACKGROUND

[0002] The precipitate discharged by the sewage treatment structure is called sludge, which is mainly composed of organic matter. The sludge is prone to putrefaction and odor, has fine particles, small specific gravity, high water content and is difficult to dewater, and belongs to hydrophilic substance with colloidal structure. The water in the sludge needs to be removed as much as possible before incineration, so as to facilitate better incineration. At present, the main drying methods are high temperature and extrusion.

[0044] In the sludge drying, first the extruded sludge is transported to the drying tank 3, at this time the hot gas flow is transported to the cavity 6 through the effect of the air inlet pipe 7, at this time the hot gas flow will enter the drying pipe inside through the effect of the air inlet hole 4 and contact the sludge, so that the sludge is heated and dried by the effect of the hot gas flow, in this process, the motor 53 is started, so the motor 53 will drive the coupling 54 to rotate, and then drive the driving shaft 55 to rotate, so that the fan 15 rotates, and then drives the rotating pipe 46 to rotate, so that the connector 47 rotates, and then drives the stirring pipe 48 to rotate, so that the stirring blade 43 rotates, so that the sludge is stirred by the effect of the stirring blade 43, so that the hot gas flow can be uniformly contacted with the sludge, and the efficiency of heating is improved, and when the fan 15 rotates, the wind power will be generated, which will be blown out to the communication pipe 19 through the bottom end of the wind shield 16, then enter the collecting pipe 20 through the communication pipe 19, and then enter the air inlet pipe 51 inside through the collecting pipe 20, at this time the wind power enters the rotating pipe 46 through the effect of the second air inlet groove 50, then enters the fixed ring 42 through the effect of the first air inlet groove 49, and finally enters the stirring blade 43 and is discharged through the air outlet hole 44, so that the wind power is finally blown to the inside of the sludge, and the sludge is dried, so as to accelerate the drying of the sludge, and the wind power in the collecting pipe 20 will also be pushed into the sealing pipe 21 connected with the collecting pipe 20 through the effect of the sealing block 27 pushed by the pushing piece 29, when the wind power enters the sealing pipe 21, it will enter the sleeve pipe 12 inside through the connecting pipe 18, so that the air pressure in the sleeve pipe 12 increases, so that the movable block 11 moves through the effect of the air pressure, so that the push rod 10 moves, and then the extrusion piece 9 moves, so that the hot gas flow in the cavity 6 is extruded by the effect of the extrusion piece 9, so that the flow velocity of the hot gas flow entering the through hole 56 increases, so that the hot gas flow can penetrate deeper into the sludge, and the drying efficiency is further improved.

[0045] It is worth noting that: the pusher 29 in the work, by the rotation of the wind wheel 15 will drive the rotating shaft 36 rotation, and then drive the rotating disc 37 rotation, thus driving the incomplete gear ring 38 rotation, and then drive the first spur gear 39 rotation, and then drive the second spur gear 40 rotation, thus driving the transmission shaft 41 rotation, and then drive the rotating block 34 rotation, thus drive the second extrusion block 33 rotation, when the second extrusion block 33 rotation to contact with the first extrusion block 31, at this time the second extrusion block 33 will extrude the first extrusion block 31 movement, thus drive the connecting column 32 fixedly connected with it movement, thus drive the sealing block 27 movement, so that the current sealing tube 21 and the collection tube 20 communication, at this time the wind into the sealing tube 21, and other sealing block 27 does not move, sealing tube 21 and the collection tube 20 does not communicate, so the wind will not enter other sealing tube 21, in the rotating block 34 continuously drive the second extrusion block 33 rotation, the second rotating block 34 will be in turn with the remaining first extrusion block 31 contact extrusion, thus arranged in groups of sealing tube 21 in turn with the collection tube 20 communication, and then the extrusion piece 9 in the plurality of cavity 6 will be in turn movement to extrude the hot gas flow.

[0046] It is particularly noted that: after extrusion, the first extrusion block 31 and the second extrusion block 33 away from each other, at this time the sealing block 27 by the action of the second spring 28 reset so that the sealing tube 21 again sealing, at this time the push rod 10 due to the action of the first spring 13 reset, ready for the next extrusion work.

[0047] It is also worth noting that: in the drying process, the hot gas flow will be transported to the inside of the drying tank 3, the extrusion piece 9 will be extruded one by one, and then improve the drying efficiency of sludge, it is particularly pointed out that: the diameter of the first spur gear 36 in the scheme is less than the diameter of the second spur gear 40, and the number of teeth of the incomplete gear ring 38 is less than 1 / 4, thus ensuring the rotation speed of the second spur gear 40 is slow, so that the first extrusion block 31 and the second extrusion block 33 away from each other for a long time, thus ensuring that there is enough wind blowing into the sleeve 12 to make the extrusion piece 9 move.
