The technical solution of the utility model is as follows:
A kind of mud low-temperature drier, specifically includes that hothouse and the sludge conveying device being located in hothouse;
One end of described hothouse is provided with charging aperture and air outlet, and the other end is provided with discharging opening and air inlet, and air inlet is provided with upper and lower deep bead, is provided with extractor fan at air outlet;
Described sludge conveying device includes guide rail, conveyer belt and two driving wheels, and two driving wheels are respectively arranged on feed inlet end and the discharge port end of hothouse, and conveyer belt is driven by driving wheel and rotates, and guide rail is then fixed on the outer surrounding of conveyer belt;Being provided with some bracing frames between guide rail and conveyer belt, one end of bracing frame is hinged with conveyer belt, and the other end can be fixed with mud plate along slide on bracing frame.
Being positioned at the mud plate above conveyer belt to tilt to charging aperture direction, mud plate is 30-45 degree with the angle of horizontal plane.
It is provided with vent passages below described mud plate and between conveyer belt.
The back side of described mud plate is welded with reinforcement, and both sides are surrounded by flanging.
Support frame as described above includes the rectangular plate-and-frame surrounded by V-shaped guide, and mud plate inserts sheet frame from the free end of guide groove, and upwards, the lower end of sheet frame is provided with two legs to sheet frame free end, and two legs are hinged with the dual-side of conveyer belt respectively.
The spacing of adjacent two mud plates can be adjusted according to the air channel size below mud plate and between conveyer belt.
Welding a short axle outside described sheet frame two free end, short axle is provided with roller, roller is arranged in guide rail.Roller can be along slide, so, when conveyer belt rotates, is slowly rotated along guide rail by the mud on traction bracing frame and mud plate.
Compared with prior art, this utility model has the advantage that
1, energy-conservation: to use low temperature and low humidity air to be dried mud, lower than the energy consumption of conventional high temperature heat drying, and air circulation system increases the flowing of air, be conducive to mud is dried, improve the treatment effeciency of mud, save energy, test result indicate that, compared with being dried with conventional sludge hot, dehydration energy reduces about 40-50%.
2, non-secondary pollution: be dried mud and be dried at the hothouse closed, baking temperature is typically below 50 DEG C, and the abnormal flavour that mud produces is few.Air closed circulation in systems is run simultaneously, and in operation, the most externally discharge has the gas of abnormal flavour.
3, technique is simple, it is easy to operation.Need not technical professional safeguard, it is easy to accomplish automatically controlling of whole system.

Detailed description of the invention
Below in conjunction with specific embodiment, this utility model is more specifically described in detail, but embodiment of the present utility model is not limited to this, for the technological parameter indicated the most especially, can refer to routine techniques and carry out.
A kind of mud low-temperature drier, including hothouse 1 and be located at the sludge conveying device in hothouse 1;
One end of described hothouse 1 is provided with charging aperture 3 and air outlet 2, and the other end is provided with discharging opening 4 and air inlet 5, is provided with upper and lower deep bead 7,6, is provided with extractor fan at air outlet 2 at air inlet 5;
Described sludge conveying device includes guide rail 8, conveyer belt 12 and two driving wheels 11, and two driving wheels are respectively arranged on feed inlet end and the discharge port end of hothouse, and conveyer belt 12 is driven rotation, guide rail 8 to be then fixed on the outer surrounding of conveyer belt 12 by driving wheel 11;Some bracing frames 10 it are provided with between guide rail 8 and conveyer belt 12, one end of bracing frame 10 is hinged with conveyer belt 12, the other end can slide along guide rail 8, and bracing frame 10 is fixed with mud plate 15, and the spacing of adjacent two mud plates can be adjusted according to the air channel size below mud plate and between conveyer belt.
