As shown in FIG. 1, the utility model provides a boiler with sludge conveying system, include: boiler body 1, boiler body 1's lateral wall middle part has been seted up the peat and has been added the mouth, and peat adds a mouthful position department and installs mud conveyor, and mud adds a mouthful entering boiler body internally from the peat through mud conveyor, and mud conveyor includes: coal breakage pipe 2, mud pipe 3, coal breakage pipe 2 install in boiler body 1's left side and coal breakage pipe 2 slope sets up, and coal breakage pipe 2's bottom adds the mouth intercommunication and links up through sealing device with the peat, and the vertical setting of mud pipe 3 is in coal breakage pipe 2's top and mud pipe 3's bottom and coal breakage pipe 2 intercommunication.

The utility model discloses offer the peat on the lateral wall of boiler body and add the mouth and install mud conveyor at peat and add the mouth, fire coal and mud enter the boiler body through not adding through conveying system respectively, avoid mud to glue the problem that the volume of coal-fired storehouse diminishes that causes on the inner wall of coal-fired storehouse when pouring into the coal-fired storehouse and mixing into, avoid the coal deposit in the coal-fired storehouse to form the phenomenon of bridging simultaneously, solve the coal-feeding machine and cut off the coal risk; the coal and the sludge are added into the boiler body together, so that the sludge and the coal in the boiler are prevented from being excessively dispersed, and a uniform mixing state between the coal and the sludge is ensured.

Because the coal dropping pipe 2 is obliquely arranged, the bottom end of the coal dropping pipe 2 is smoothly processed, the flow velocity of the coal at the bottom of the coal dropping pipe 2 is slowed down, and in order to avoid the blockage of the coal at the bottom of the coal dropping pipe 2, the utility model discloses still set up the tuber pipe 4, the tuber pipe 4 level is set up in the left side of the boiler body 1 and the right-hand member of the tuber pipe 4 is communicated with the coal dropping pipe 2, the air-blast device is installed at the left end of the tuber pipe 4, and the blockage of the bottom end of the coal dropping pipe 2 is avoided simultaneously when air is injected into the boiler body 1 through the tuber pipe; meanwhile, enough oxygen can be introduced to fully combust the fire coal in the boiler body 1.

Because the vertical setting of mud pipe 3 that falls, the falling speed of mud in mud pipe 3 that falls is very fast, produces vibrations easily, for reducing the influence that vibrations caused to mud pipe 3 that falls, the utility model discloses set up expansion joint 5 at the middle part of mud pipe 3 that falls.

As shown in figure 2, the utility model discloses a mud adopts following structure to carry in the mud pipe that falls and pours into boiler body 1 into through the mud pipe into, and excessive 7 of fighting of mud is installed at the top of mud pipe 3 that falls, and the top of mud pipe 3 and the bottom export intercommunication that excessive 7 were fought to mud, and mud is carried through conveyer belt 8 and is fought in 7 excessively to mud.

Because the higher surface of attaching to conveyer belt 8 easily of the moisture content of mud when adopting conveyer belt 8 to transport mud, the mud that attaches to 8 surfaces on conveyer belt bonds on the conveyer belt surface at return stroke section mummification, can reduce conveyer belt 8's load-carrying capacity in the past this long term, for solving above-mentioned problem the utility model discloses clean piece 9 at conveyer belt 8's tip installation, will attach to in the mud on conveyer belt 8 surface clears up and fall to the mud excessively to fight 7 in through cleaning piece 9.

Because the suitable volume diverse that adds mud of different boilers, in order to adjust the volume of adding mud according to the firepower and the size of different boilers, the utility model discloses a driving motor of conveyer belt 8 who adopts can adopt the mode regulation rotational speed of frequency conversion, thereby control mud through regulation rotational speed and add the speed that gets into in the boiler body 1.

Because the slope of coal breakage pipe 2 sets up, the bottom of coal breakage pipe 2 links to each other with boiler body 1, and the tie point between coal breakage pipe 2 and the boiler body 1 is too few, and the coal-fired can cause vibrations when removing in coal breakage pipe 2, for the stability of being connected between reinforcing coal breakage pipe 2 and the boiler body, the utility model discloses still set up: connect channel-section steel 6, the first end of connecting channel-section steel 6 links to each other with the left side wall of boiler body 1 is fixed, and the second end of connecting channel-section steel 6 links to each other with coal breakage pipe 2 is fixed.
