Abstract
The utility model discloses a conducting tube type sludge drying machine, mainly comprising a screw conveyer, a shell, a center rotating drum, a driving motor and a discharge device. The conducting tube type sludge drying machine is characterized in that a feed conveyor is arranged between the screw conveyor and a dewatering sludge bin; a steam outlet and a steam inlet are respectively formed in the upper parts of two ends of the shell; the center rotating drum is connected with the driving motor; and conducting tubes are arranged in the center rotating drum. The conducting tube type sludge drying machine has the beneficial effects that a heat source is used for performing indirect heating, so that the water content of sludge can be further reduced; the characteristics of efficient heat energy recovery and high automation degree are obtained; the heat transfer area of the conducting tubes is large to ensure that the general water convent of about 80% of the sludge can be quickly reduced to about 40%, so that the water content of the sludge is obviously reduced; an air circulation system is arranged on the drying machine to quickly take away the water evaporated from the sludge; a temperature sensor is also arranged on the drying machine, can run automatically, and is convenient to operate; and the conducting tube type sludge drying machine adopts a fully-closed system, so that secondary pollution caused by the sludge is reduced, and the requirement for resource utilization can be met.
Description
Technical field
The utility model relates to a kind of conduction tubular type sludge drying machine, belongs to the environmental protection technical field of sludge treatment.
Background technology
Along with the urbanization process of China 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 to be done further processing, if mud can not get reasonable processing, will cause secondary pollution.According to statistics, the town sewage treatment facility that puts into operation in the existing whole nation is thousands of seats altogether, the annual mud (dry weight) that produces is more than 1,000 ten thousand tons, and annual growth nearly 10%, the processing disposal costs of sewage sludge is higher, in whole construction costs of wastewater treatment in China factory, account 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 at present multiplely for urban sludge treating method, 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 mummification can apply to land reclamation, building materials utilization etc.How to reduce the water ratio of mud, this is the vital task of sludge treatment.
The utility model content
The purpose of this utility model is to overcome the shortcoming and defect of above-mentioned prior art, and a kind of conduction tubular type sludge drying machine is provided, and utilizes the thermal source indirect heating, can further reduce moisture percentage in sewage sludge, has high efficient heat recovery, the characteristics that level of automation is high.
The purpose of this utility model is achieved through the following technical solutions: a kind of conduction tubular type sludge drying machine, mainly formed by worm conveyor, shell, central drum, drive-motor and dumping device, it is characterized in that: be provided with feeding conveyor between described worm conveyor and dewatered sludge storehouse; The top, two ends of described shell is provided with vapour outlet and steam-in; Described central drum is connected with drive-motor; Described central drum inside is provided with conducting tube.
The top, two ends of described central drum is provided with airout and gas inlet.
Further, described outer casing bottom is provided with anterior temperature sensor, middle part temperature sensor and rear part temperature sensor.
Principle of work of the present utility model: after the mud of sewage work carries out thickening, water ratio is that 80～85% mud enters the dewatered sludge storehouse, feeding conveyor arrives the helical feed machine inlet capable with sludge lifting, mud enters central drum inside from worm conveyor, drive-motor drives central drum and rotates, central drum has certain angle of inclination, and sludge stream is to dumping device; Steam enters into conducting tube inside by the steam-in, and conducting tube is heated mud is heated; Be heated by the mud conducting tube and carry out transpiring moisture, enter central drum from gas inlet, carry out air circulation system, take away rapidly the moisture of mud evaporation; The anterior temperature sensor that is provided with at shell, middle part temperature sensor and rear part temperature sensor are controlled the size of quantity of steam, monitoring shell 5 internal temperatures, automatic operating; Mud is discharged from discharge port by dumping device.
In sum, the beneficial effects of the utility model are: utilize the thermal source indirect heating, can further reduce moisture percentage in sewage sludge, has high efficient heat recovery, the characteristics that level of automation is high, the heat transfer area of conducting tube is large, can make general moisture percentage in sewage sludge be about 80% and be reduced to very soon 40% left and right, has obviously reduced the water content of mud; And be furnished with air circulation system, take away rapidly the moisture of mud evaporation; 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.
