Description
Technical field
The utility model relates to a kind of sludge dewatering drying installation, is specifically related to a kind of being heated by resistive mud is carried out the exsiccant device.
Background technology
With biochemical process sewage is carried out inevitably can producing mud in the treating processes, the high-moisture percentage of mud and difficult dehydration property become it to be handled and the major obstacle of utilizing.At present, the national sewage work wet mud of annual discharging is more than 6,000,000 tons, and these are not stabilized in a large number, the mud of harmless treatment has become the heavy burden of sewage work, again environment have been produced secondary pollution simultaneously.And contain many useful compositions in the mud, can through processing being used.That method for sludge treatment commonly used has is agricultural, three kinds of landfill and burnings, and reducing the mud moisture content is the key of sludge treatment.Traditional mud concentrates with mechanical dehydration technology can only reduce to 65%-75% with the mud moisture content, deep dehydration need adopt heated drying.
Occurred two kinds of mud heated drying devices at present, first kind is the solar heat drying installation, and second kind is the micro-wave drying device.These two kinds of devices all have advantages such as working cost is low, environmentally safe, but the heating efficiency of solar heat drying installation is lower, and the energy consumption of micro-wave drying device is higher, the complex structure of these two kinds of devices of while, all suitable large-scale promotion.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of electric resistor heating type sludge dewatering drying installation, can carry out deep dehydration to mud, and is simple in structure and energy consumption is lower.
The technical scheme that the utility model adopts is: comprise buncher, and the left end of the horizontal connecting screw rod of output shaft of buncher, screw rod is positioned at pipe; Interior pipe overcoat outer tube is provided with several heating resistors between outer tube wall and outer wall of inner tube, several heating resistors series connection backs connect the voltate regulator of outside; The vertical mud inlet that is connected with interior pipe that is provided with in interior pipe left end top is provided with the sludge outlet that is connected with interior pipe bottom interior pipe right-hand member; In interior pipe, on the section of the left side of screw rod, Disintegrating knife is set, on the right section of screw rod screw-blade is set, the pitch between each blade of screw-blade is reducing on the direction of sludge outlet gradually.
The utility model is simple in structure, and heating efficiency is high, and dewatering efficiency is good, and does not have secondary pollution, can extensively promote.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 be among Fig. 1 A-A to view;
Among the figure: the 1-buncher; 2-mud inlet; Pipe in the 3-; The 4-outer tube; The 5-heating resistor; The 6-screw rod; The 7-screw-blade; The 8-Disintegrating knife; The 9-vapour outlet; The 10-sludge outlet; The 11-water leg; The 12-filter cloth; The 13-water outlet; The 14-electric wire; The 15-voltate regulator; The 16-support.
Embodiment
The sludge dewatering drying installation of the utility model comprises the left end of the horizontal connecting screw rod 6 of output shaft of buncher 1, buncher 1; Screw rod 6 horizontal positioned; And be positioned at pipe 3, interior pipe 3 overcoat outer tubes 4, interior pipe 3 all is cylinder structures with outer tube 4; Outer tube 4 uses thermal insulation material, and interior pipe 2 adopts thermally conductive material.Be provided with several heating resistors 5 in the space between the outer wall of the inwall of outer tube 4 and interior pipe 3, all heating resistors 5 series connection backs connect outside voltate regulator 15 through electric wire 14.The bottom of whole device is supported through support 16.
On interior pipe 3 tops near buncher 1, mud inlet 2 vertically is set on pipe 3 the left end top in promptly, the opening of mud inlet 2 and is connected with interior pipe 3 up, in mud gets into through this mud inlet 2 in the pipe 3.In the right-hand member of interior pipe 3 bottom sludge outlet 10 is set, the opening of sludge outlet 10 and is connected with interior pipe 3 down.Right-hand member top at interior pipe 3 is provided with vapour outlet 9.In interior pipe 3, on the section of the left side of screw rod 6, Disintegrating knife 8 is installed, the right section of screw rod 6 goes up installs screw-blade 7, and the pitch between each blade of screw-blade 7 is reducing on the direction of sludge outlet 10 gradually.Be provided with water leg 11 in the bottom of interior pipe 3, water leg 11 tops cover one deck filter cloth 12, and the bottom of water leg 11 is provided with water outlet 13, the opening of water outlet 13 vertically downward, water leg 11 be shaped as circle or rectangle,
During the utility model operation; Be that 80% mud adds from mud inlet 2 with water ratio; Start buncher 1 simultaneously and connect heating resistor 5; Screw rod 6 rotates under the driving of buncher 1, and the mud of larger particles at first is ground into small-particle under the effect of Disintegrating knife 8, and then under the effect of screw-blade 7, is transported to sludge outlet 10.In the process of carrying through screw-blade 7, because the pitch between the blade reduces gradually, mud is formed extruding to a certain degree, play the effect of auxiliary dehydration.The water that produces in the drying sludge process is at first filtered by filter cloth 12, is collected together by water leg 11 then, discharges through water outlet 13 again.Can change Heating temperature through regulating voltate regulator 15 in the operational process, make sludge dewatering reach best effect.The water vapour that in dehydration, produces volatilizees away through vapour outlet 9.
