Abstract
The utility model relates to a sludge compost fermentation treatment device, comprising a feed opening 1, a main drum 2, a discharge opening 3 and a power unit 4 arranged at the bottom of the device. The utility model overcomes the shortcomings of the long composting time, large occupied area and incomplete mud fermenting in the traditional composting method, and has the advantages of small occupied area, flexible operation, low energy consumption, improved mud fermenting efficiency for the adoption of the horizontal drum in the mud fermenting process, and short fermentation period. After the thermophilic aerobic fermentation in the fermentation tank, the mud is changed into humic particles with nice shapes, and then quantitative nutritive materials are added according to the different needs of the agricultural fertilizers, and further processed into finished fertilizers for agriculture and selling.
Description
The utility model relates to a kind of sludge composting fermentation unit that is used for the city sewage and sludge stabilizing treatment.
The mud that produces in the sewage treatment process has water ratio height, perishable, foul smelling, and contains characteristics such as parasitic ovum and pathogenic micro-organism.As not dealt carefully with, discharging will cause secondary pollution arbitrarily.On the other hand, mud also is a kind of effective bioenergy, contains nutritive substances such as abundant nitrogen, phosphorus, potassium.Reasonably develop mud, both can solve problem of environmental pollution, can be agroforestry again and open up organic fertilizer resource.
The mechanize composting technology is to have under the condition of control, utilizes microorganism to perishable organism biodegrade in the mud, makes it to become the process of the peat shape fertilizer with good stability.Mud adds some adjust agent or raising agent and mix after, ventilate, oxygen supply, carry out biochemical degradation through the aerobic microorganism, be converted into the material of good peat shape.
The sludge aerobic fermented manure technology of researching and developing both at home and abroad all is the zymotechnique device that adopts charging, stirring, ventilation, discharging to carry out simultaneously at present, and its core is the aerobic fermentation groove.And fermenter can be divided into several classes according to shape: the vertical multi-sectional fermenter; The silo-type fermenter; Horizontal rotation fermenter; Horizontal open fermentation groove.The treatment capacity of vertical multi-sectional fermenter mode is big, and floor space is less, but material is mixed inhomogeneous, and the investment of equipment is higher; The compacting phenomenon easily takes place because the bed of material is very high in the silo-type fermenter, produces the part anaerobic state, gives out a foul smell; The low price of horizontal rotation fermenter equipment, easy handling; In all kinds of fermentation units, advantage such as workable, the easy equipmentization of horizontal rotation fermentation unit, power consumption are little.
The purpose of this utility model is to provide a kind of efficient cylinder sludge composting equipment.Compare with the common mechanical composting device, it has not only overcome long, shortcoming such as floor space is big, sludge fermentation is incomplete of traditional composting mode compost time well, and have that floor space is little, advantage such as flexible operation, energy consumption are low.Be suitable for the harmless treatment of municipal sewage sludge.
The purpose of this utility model is achieved in that a kind of sludge treatment equipment, and it mainly comprises opening for feed, equipment body cylinder fermentation reaction groove, discharge port and is arranged on the power set of cylinder bottom.
Utilize the excess sludge of municipal sewage plant to make raw material, make organic composite fertilizer, this not only provides biological organic fertilizer for the volume increase of agricultural and gardens industry, replenish China's chemical fertilizer wretched insufficiency, has very big economic benefit, simultaneously, solve the pollution problem that the serious day by day city sewage and sludge that increases causes, solved the final problem of outlet of mud.It will have far-reaching social effect to the development of beautifying the environment, promote the environment industry.
Below in conjunction with accompanying drawing and example the utility model is described in further details:
Fig. 1 is the structural representation of the utility model sludge composting fermentation equipment.
Fig. 2 is the part sectioned view of Fig. 1.
1, opening for feed; 2, cylinder fermenter; 3, discharge port; 4, power set; 5,
Blade.
A kind of sludge composting fermentation equipment, it comprises that mainly opening for feed 1, equipment body roll
Tube fermentation reaction groove 2, discharge port 3 and be arranged on the power set 4 of cylinder bottom.
Inner wall of rotary drum welding blade is isosceles triangle by sense of rotation to be arranged, and the angle of inclination is 2 °,
Whole cylinder tilts 5 ° vertically.
See also Fig. 1, Fig. 2, raw material add from upper end opening for feed 1, cylinder fermenter 2 slowly rotates, under the rolling and downslide effect of cylinder, slowly shift to lower end discharge port 3, in this process, cylinder is rotated, the mixing of material and the supply of air take place, realize that mud ferments rapidly under the condition of aerobic by power set 4.Inner wall of rotary drum welding blade is isosceles triangle by sense of rotation to be arranged, and the angle of inclination is 2 °, plays the effect of stirring material and limiting Flow of Goods and Materials speed.Whole cylinder tilts 5 ° vertically, and from high endfeed, material is slipped to low side discharge port outflow cylinder in rolling.(0.75KW 220V) through bipolar cycloid speed reducer, adopts the gear-wheel gear-ring type of drive to drive rollers roll, and rotating speed is 0.03 rev/min, peak torque 4300NM by alternating current motor in power section.
The fermenting process of mud has adopted horizontal drum, and mud adds from the upper end, and by intermittence rotation and forced ventilation, mud flows out from the lower end.Thereby improved sludge fermentation efficient.Fermentation period shortens to 3～10 days.Through high-temperature aerobic fermentation in fermenter, mud becomes the good corruption of proterties and plants particle.Can add chemical feedstockss such as a certain proportion of nitrogen, phosphorus, potassium according to different agricultural fertile N, P, K equal size standards then, enter prilling granulator after pulverizing, stirring, drying, screening are put in storage or are sold after becoming finished product packing after the moulding.
According to comparison to existing device type and processing property, on the basis of horizontal rotor fermenter, develop drum-type sludge composting fermentation equipment, greatly improved the sludge composting reaction efficiency.The utility model sludge composting fermentation equipment has solved long, shortcoming such as floor space is big, sludge fermentation is incomplete of traditional composting mode compost time well.Compare with the common mechanical composting device have also that floor space is little, advantage such as flexible operation, energy consumption are low.Be suitable for the harmless treatment of municipal sewage sludge.Has good popularizing application prospect.
