Throwing wheel device for sludge aerobic fermentation

Technical Field

The utility model belongs to the technical field of the mud is dealt with, concretely relates to mud is throwing wheel device for aerobic fermentation.

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 cannot be performed, a good oxygen environment cannot be provided for strains, and aerobic fermentation cannot be continuously performed, so that the part of sludge is conveyed out, scattered and easily stirred so as to be conveyed into the fermentation tank for secondary fermentation, and the problem to be solved at present is solved urgently.

SUMMERY OF THE UTILITY MODEL

The utility model overcomes prior art's is not enough, provides one kind can throw and send, break up siltation mud, provides better fermentation condition for mud secondary fermentation.

In order to solve the technical problem, the utility model discloses a throwing wheel device for mud aerobic fermentation sets at aerobic fermentation mud discharge gate, including throwing wheel driving piece and driven throwing wheel, the throwing wheel includes the cylinder and sets firmly the material tooth piece of dialling at the cylinder outer wall, and throwing wheel driving piece driving roll rotates, drives and dials the material tooth piece and rotates, smashes the mud material and throws the mud material, throws it to the material discharge gate.

Preferably, the material poking toothed sheets are arranged in a plurality and spirally distributed on the outer wall of the roller.

Preferably, each material shifting toothed sheet is connected to form a spiral shape and is installed on the outer wall of the roller.

Preferably, the outer edge of the material poking toothed sheet is in a sawtooth shape.

Compared with the prior art, the beneficial effects of the utility model include: the sludge is cut and turned through the material stirring toothed sheets on the outer wall of the roller, so that the sludge is broken and scattered, a foundation is provided for the sludge conveying and the good oxygen environment in contact with the secondary fermentation, the sludge heat dissipation is facilitated, and the odor generated by the sludge fermentation outside the fermentation box is prevented.
