Abstract
The utility model discloses a double-rotary drum sludge drying machine. The machine mainly comprises a shell, a first central rotary barrel, a first rotary drum, a second rotary drum, an upper sealing cover, a transmission gear, a conveying belt, a drive gear, a drive motor and a second central rotary barrel. The machine is characterized in that the upper sealing cover is arranged on the top of the shell; the first central rotary barrel is connected with the first rotary drum, and the inner cavities of the first central rotary barrel and the first rotary drum are communicated with each other; and the second central rotary barrel is connected with the second rotary drum, and the inner cavities of the second central rotary barrel and the second rotary drum are communicated with each other. By utilizing the double-rotary drum sludge drying machine, the water content of sludge can be further reduced; and the machine has the characteristics of double rotary drums, indirect heating, difficulty in generating sludge blocks in the drying machine and small quantity of waste gases.
Description
Technical field
The utility model relates to the double rotating drum sludge drier, belongs to environmental technology field.
Background technology
Along with urbanization process is accelerated, industrial developing rapidly, the increase of urban population, the quantity discharged of urban industry waste water and sanitary sewage is increasing, and treatment rate of domestic sewage also improves year by year, and the sludge yield of municipal sewage plant also sharply increases.A large amount of excess sludges will discharge in sewage work, and the mud of enormous amount need be done further processing, if mud can not get reasonable processing, will cause secondary pollution.According to statistics, the processing disposal costs of sewage sludge is higher, in whole construction costs of sewage work, accounts for 20%～50% for the treatment of mud.The composition of sewage sludge is very complicated, except containing a large amount of moisture, also contains a large amount of useful resources.Have multiplely at present for the municipal sludge treatment process, landfill, burning and comprehensive utilization are generally arranged, but before recycling, need carry out pre-treatment to mud, nurse one's health, comprise concentrated, dehydration, drying.Mud through after the mummification can apply to land reclamation, and how building materials utilization etc. reduce the water ratio of mud, and this is the vital task of sludge treatment.More existing sludge driers adopt the steam direct heating, have the shortcoming that produces waste gas; Adopt the indirect heating sludge drier in addition, but in drying machine, produce the mud caking easily.
The utility model content
The purpose of this utility model is to overcome the shortcoming and defect of above-mentioned prior art, the double rotating drum sludge drier is provided, can further reduce moisture percentage in sewage sludge, have difficult mud caking, the few characteristics of generation waste gas of producing in double rotating drum, indirect heating, the drying machine.
The purpose of this utility model is achieved through the following technical solutions: the double rotating drum sludge drier, mainly be made up of shell, first central drum, first rotary drum, second rotary drum, upper cover, wheel box, conveying belt, driving gear, drive-motor and second central drum, it is characterized in that: described upper cover is arranged on the top of shell; Described first central drum is connected with first rotary drum that inner chamber communicates; Described second central drum is connected with second rotary drum that inner chamber communicates.
Be provided with some plectrums on described first rotary drum and second rotary drum.
The side of described shell is provided with observation window.
The both sides end socket of described shell is provided with steam-in and vapour outlet.
Further, described first rotary drum and second rotary drum are provided with driving gear.
In sum, the beneficial effects of the utility model are: adopt the indirect steam heating, the heat transfer area of double rotating drum drying tray is big, can make general moisture percentage in sewage sludge be about 80% and be reduced to very soon about 40%, has obviously reduced the water content of mud; The plectrum that arranges on first rotary drum and second rotary drum effectively prevents from producing in the drying machine mud caking; And be furnished with air circulation system, take away the mud moisture evaporated rapidly; Disposing temperature sensor can automatic operating, easy to operate; The utility model adopts totally-enclosed system, has reduced the secondary pollution of mud, can arrive the requirement of recycling.

Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but embodiment of the present utility model is not limited only to this.
Embodiment: as Fig. 1, Fig. 2, shown in Figure 3, the utility model mainly is made up of shell 2, first central drum 5, first rotary drum 6, second rotary drum 8, upper cover 12, wheel box 16, conveying belt 18, driving gear 20, drive-motor 21 and second central drum 23, and it is characterized in that: described upper cover 12 is arranged on the top of shell 2; Described first central drum 5 is connected with first rotary drum 6 that inner chamber communicates; Described second central drum 23 is connected with second rotary drum 8 that inner chamber communicates.
Be provided with some plectrums 7 on described first rotary drum 6 and second rotary drum 8.
The side of described shell 2 is provided with observation window 10.
The both sides end socket of described shell 2 is provided with steam-in 4 and vapour outlet 19.
Further, described first rotary drum 6 and second rotary drum 8 are provided with driving gear 20.
During sludge drier operation work: water ratio is about 80% after the sludge dewatering, mud enters sludge drier inside from mud import 1, pass backward under plectrum 7 effects on first rotary drum 6 and second rotary drum 8, plectrum effectively prevents from producing in the drying machine mud caking.Steam enters into first central drum 5 and second central drum, 23 inside by steam-in 4, and steam is heated drying tray from the inner chamber that steam hole enters first rotary drum 6 and second rotary drum 8; Carry out transpiring moisture by the drying tray that is heated, air circulation system is taken away the mud moisture evaporated rapidly; The size of the temperature sensor 15 control quantity of steams that are provided with in shell 2 inside is regulated shell 2 internal temperatures, and automatic operating is easy to operate; Can make general moisture percentage in sewage sludge be about 80% and be reduced to very soon about 40%, obviously reduce the water content of mud; The utility model adopts totally-enclosed system, has reduced the secondary pollution of mud, can arrive the requirement of recycling.
As mentioned above, just can realize the utility model preferably.
