Sludge drying biax plough ejection of compact machine

Technical Field

The utility model belongs to the technical field of the sludge is dealt with, concretely relates to sludge drying biax plough ejection of compact machine.

Background

The sludge is rich in organic matters causing water body pollution, nitrogen, phosphorus, potassium and other nutrient elements, contains a large amount of pathogenic microorganisms, is easy to decay and smell, can cause serious environmental pollution and ecological damage if not properly treated, and is also a great resource waste. At present, only about 10-20% of sludge in China is treated safely and harmlessly, and a large amount of sludge cannot be treated effectively. Thirteen-five' period is a success stage of comprehensively building a well-being society in China, and is an important period for converting an economic development mode to obtain substantial progress. Therefore, during the 'thirteen-five' period, further planning and reasonable layout are needed, the investment is increased, the conversion from scale increase to quality improvement and efficiency improvement of the construction of the urban facilities is realized, the conversion from heavy water light mud to mud water is repeated, and the conversion from sewage treatment to regeneration and utilization is realized, so that the guarantee capability and the service level of the urban sludge treatment facilities in China are comprehensively improved, and the masses can really feel the effect of improving the environmental quality.

In order to enhance the treatment and disposal of the sludge, the Ministry of construction and building and the Ministry of environmental protection have organized "national urban ecological protection and construction planning (2015-2020"), and stipulate that the harmless treatment rate of the municipal solid wastes reaches 95 percent and the harmless treatment and disposal rate of the municipal sludge at grade and above reaches 90 percent.

At present, the main domestic and foreign treatment modes of sludge treatment are landfill, drying incineration and land utilization, and an anaerobic digestion technology and an aerobic fermentation technology are mainly applied to the treatment process. The sludge aerobic fermentation technology is a new biological treatment technology for fermentation by utilizing microorganisms in sludge, namely, a certain proportion of leavening agent and conditioning agent is added into the sludge, and a microbial community is utilized to carry out oxidative decomposition on various organic matters under a humid environment and convert the organic matters into humoid with higher stability, so that the effects of stabilization, harmlessness, reduction and resource utilization can be achieved in practical application, and the sludge aerobic fermentation technology has the characteristics of economy, practicability, no additional energy source, no secondary pollution and the like, and is a practical technology suitable for sludge treatment and disposal.

The aerobic fermentation technology has been developed greatly in recent years, and the aerobic fermentation technology is adopted currently in China, particularly in most cases in south China with sludge treatment. However, aerobic fermentation still faces more factors restricting further application thereof, and mainly comprises floor space, auxiliary materials, intelligent control, miniaturization, device integration, microbial inoculum inoculation, odor treatment and the like.

With the support of the relevant national industrial policy, aerobic fermentation or aerobic fermentation will become one of the mainstream processes for solving the problem of urban sludge discharge. The urban sludge is treated by aerobic fermentation, particularly small-sized intelligent sludge aerobic fermentation technical equipment, has the advantages of small land occupation, high automatic control degree, stable operation, quick temperature rise, thorough harmlessness, low odor, realization of resource utilization and the like, solves the urban sludge treatment problem, eliminates the threat of urban sludge secondary pollution environment, achieves the purposes of stabilization, harmlessness, reduction and resource utilization of sludge treatment and disposal, and has very wide market prospect and application value. However, the lower part of the pile body of the sludge piled in the existing aerobic fermentation tank can be compacted, normal ventilation can not be carried out, a good oxygen environment can not be provided for strains, and aerobic fermentation can not be continuously carried out, so that the part of sludge is conveyed out to be stirred again and then is conveyed into the fermentation tank for fermentation, which becomes the problem to be solved at present.

SUMMERY OF THE UTILITY MODEL

The utility model overcomes the defects of the prior art, provides a sludge drying double-shaft plow type discharging machine which can effectively cut and transport the compacted sludge at the bottom of a fermentation box so as to realize the circulating transportation of an aerobic fermentation system and improve the aerobic fermentation.

In order to solve the technical problem, the sludge drying double-shaft plough type discharging machine of the utility model is characterized in that at least two rotating shafts arranged side by side are arranged in a discharging machine shell, the outer wall of each rotating shaft is provided with a plurality of plough coulter type blades, and the plough coulter type blades are spirally distributed on the outer wall surface of each rotating shaft; the rotating directions of the two rotating shafts are the same or opposite, the upper part of one end of the shell of the discharging machine is communicated with a discharging port of the fermentation box, the other end of the shell of the discharging machine is provided with a material discharging port, and the rotating shafts cut and convey materials through coulter type blades.

Preferably, the coulter type blades are uniformly arranged on the rotating shaft, the outer edges of the coulter type blades are provided with coulter tips for beveling materials, and the coulter tips are arranged in the direction of the coulter type blades departing from the material conveying direction.

Compared with the prior art, the beneficial effects of the utility model include: through the rotation of the rotation axis of arranging side by side, no matter the rotation direction is the same or opposite direction, homoenergetic stirs the mud that deposits the compaction after aerobic fermentation, utilizes the cooperation to set up the coulter formula blade cutting sludge material at its outer wall to utilize coulter formula blade propelling movement material to export, realize the transport to the sludge material of fermentation tank bottom.
