Embodiment one：
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of energy saving and environment friendly sludge incineration device, including combustion furnace 1, separator 2, it is described
The air inlet pipe of separator 2 is communicated to the furnace chamber of combustion furnace 1, and its bottom is communicated to the furnace chamber of combustion furnace 1 by refeed line 3, also wraps
Include sludge delivery pump 4；The top of the refeed line 3 is provided with sludge inlet 5, and the discharge nozzle 41 of the sludge delivery pump 4 is communicated to
Sludge inlet 5.Also include charging gear 6, the charging gear 6 include barrel 61,62, depression bar 63 of cutting somebody's hair, motor 64 and
Mesh plate 65；The discharge nozzle 41 of the sludge delivery pump 4 is communicated to barrel 61, and the bottom of the barrel 61 is connected to sludge inlet
5, its bottom is provided with mesh plate 65；Described to cut somebody's hair 62 in barrel 61, top is provided with depression bar 63, and the motor 64 drives
The depression bar cuts somebody's hair 62 in the interior motion of barrel 61 so as to drive.
Motor 64 is fixed by the support on combustion furnace 1 or refeed line 3, and its output shaft is provided with gear
Group, the side of depression bar 63 also is provided with rack, coordinates with gear train, realizes that motor 64 drives depression bar 63 with this.
Sludge delivery pump 4 is drawn after sludge, is delivered to through discharge nozzle 41 in barrel 61, and the driving depression bar 63 of motor 64 is transported
Dynamic, drive cuts somebody's hair 62 in the interior extruding sludge of barrel 61, and sludge enters sludge inlet 5 from the mesh plate 65 of the bottom of barrel 61, so that
The furnace chamber for entering combustion furnace 1 by refeed line 3 is burnt.
Sludge falls into furnace chamber from refeed line 3, is the top feed from furnace chamber internal-combustion flame, compared to traditional bottom feed
When sludge bottom can not fully catalytic combustion flame and the burning that causes is insufficient, top, which is fed, causes sludge sufficiently in burning flame
Contact, so that burning is more abundant.
Moreover, sludge is when by refeed line 3, refeed line 3 has carried out a certain degree of drying to it, reduces its aqueous
Amount, therefore it is more easy to fully burning.
On the other hand, sludge passes through the extruding of charging gear 6, after mesh plate 65, and sludge is into fine strip shape, the dirt of fine strip shape
Mud is more easy to drying, and increases the contact area with burning flame significantly, meanwhile, the sludge of fine strip shape is conducive to fluidisation, in operation
During sludge is fully burnt, eliminate environment protection emission hidden danger not up to standard.Effectively solve blast cap blockage problem.And the thermal effect of boiler
Rate gets a promotion.
As shown in Figure 3：62 internal diameter of external diameter and barrel 61 of cutting somebody's hair matches, barrel 61 and cut somebody's hair 62 cooperation,
Just as a piston syringe, lifting extruding efficiency, that is, add charge efficiency.
As shown in Figure 3：The discharge nozzle 41 of the sludge delivery pump 4 is communicated to the side bottom of barrel 61, therefore, is cutting somebody's hair 62
In extrusion process, the sustainable conveying sludge of sludge delivery pump 4 further increases delivery rate, raising efficiency.
As shown in figure 4, also including automatic control system；The automatic control system includes 89C52 chips, high temperature pressure and passed
Sensor, liquid level sensor, relay A, relay B, relay C；

Tri- interfaces of P00, P01, P02；The forward and backward that described relay A, B normally opened contact are connected serially to motor respectively is powered
In circuit, when relay A works, motor 64 is rotated forward, and drives 62 extruding sludge of cutting somebody's hair, when relay B works, motor
64 reversions, 62 returns of cutting somebody's hair, sludge enters figure barrel 61, preparation feed next time.
The normally opened contact of the relay C is connected serially in the power supply circuit of sludge delivery pump 4.When relay C works, sludge
Delivery pump 4 is started working, otherwise is stopped.
By setting the setting value (pressure size of bottom residual residue content after hearth combustion) of high-temp pressure sensor,
Detect whether burner hearth bottom has sludge to burn with this, if reaching setting value, prove that burner hearth bottom is burning without sludge,
Then deliver a signal to 89C52 chips, chip output current to relay A, relay A normally opened contacts closure, 62 pressing materials of cutting somebody's hair
Sludge in cylinder 61 enters combustion furnace 1；Sludge is reached after burner hearth, and high-temp pressure sensor, which is perceived, has sludge in burning, then passes
Delivery signal gives 89C52 chips, chip output current to relay B, and its normally opened contact closure, motor 64 is inverted, and cuts somebody's hair 62
Return.
When sludge is less than liquid level sensor in barrel 61, then 89C52 chips, chip output current to relay are delivered a signal to
Device C, relay C normally opened contact are closed, and sludge delivery pump work, sludge reaches after liquid level sensor height that then relay C is normally opened
Contact disconnects, and sludge delivery pump is stopped.Repeat to circulate above.
This set control system can realize autofeed, remove artificial operation from, reduce human cost.
As shown in figure 1, the end of the discharge nozzle 41 is provided with valve 42.
