Background
The municipal solid waste mainly refers to solid waste produced by units and residents in cities in daily life and living services. The urban domestic garbage production in China increases at a speed of 8% -10% every year. At present, the stock of domestic urban domestic garbage reaches 62 hundred million tons, the domestic urban domestic garbage production amount in 2004 is close to 2.6 million tons, wherein 80% -90% of domestic urban domestic garbage comes from large and medium-sized cities, the garbage amount produced by each person in each city per day is about 1.2kg, the treatment rate is only about 50%, and about more than 200 large and medium-sized cities are enclosed by the urban domestic garbage. With the rapid development of economy and the improvement of living standard, the proportion of recoverable waste products and organic garbage in the municipal domestic garbage is gradually increased. In the process of collecting and transferring garbage, organic matters in the garbage can be rotten and go bad to generate stink; some garbage contains waste used by disease patients and even excrement, and if the garbage is randomly stacked, pathogenic microorganisms permeate the underground along with rainwater to pollute underground water sources, so that urban living environment and public health are directly or indirectly harmed. Therefore, the adoption of a novel and efficient municipal domestic waste source treatment technology is a necessary way for realizing the sustainable development of cities.
In the current organic waste microbial treatment technology, as a new development direction for solving the problems, the microbial degradation bacteria are utilized to generate a plurality of enzymes, such as protease, lipase, amylase, chitinase, cellulase, oxidase, hydrolase and the like, and classified organic waste (mainly kitchen waste, including fruit peel, vegetable leaves, vegetable roots, waste paper, food residues, chicken, duck and fish waste, crab shells, egg shells, bones, swill and the like) is rapidly decomposed, so that the organic waste is converted into carbon dioxide, water and a small amount of NH 3; after the organic garbage is treated by the organic garbage microbiological treatment machine, about 4 percent of substances remain in the biological matrix, and the residues mainly comprise inorganic mineral substances, bacteria bed matrix, microorganism residues and the like which remain after the organic garbage is decomposed by microorganisms. The results of tests on the organic domestic waste residues treated by the microorganism treatment equipment by related research institutions show that various indexes of the residues are beneficial to the improvement of soil, wherein the organic matter accounts for 82.5%, the total N, the total P (P2O5) and the total K (K2O) respectively account for 0.037%, 0.966% and 2.88%, and the fertilizer efficiency is equivalent to that of organic fertilizer. Therefore, the residues of the organic garbage treated by the equipment can be digested nearby, generally can be directly reused for soil improvement or garden construction, and are not required to be transported to a landfill site for landfill, so that the sustainable utilization of the garbage is realized, the volume reduction rate of the organic garbage microbial treatment technology can reach 100%, the volume reduction rate can reach more than 96%, meanwhile, the residues of the organic garbage treated by the equipment can be digested nearby, generally can be directly reused for soil improvement or garden construction, and are not required to be transported to the landfill site for landfill, so that the sustainable utilization of the garbage is realized, the pollution of a chemical fertilizer to soil and environment is abandoned, a new business opportunity is brought for the construction of the future green environment, and the harmless, reduced and recycled treatment of the organic garbage is really realized; meanwhile, the organic garbage microbial treatment technology has the characteristics of wide application range, low investment, no secondary pollution and the like, completely meets the requirement of urban sustainable development, and is an effective way for realizing harmless, quantitative and resource treatment of urban domestic garbage sources in China as soon as possible.
Meanwhile, in the existing organic waste microorganism treatment equipment (see chinese patents CN111495927A and CN109940026B), organic waste is crushed and then sent into a fermentation tank (or called reaction chamber) to be accelerated to decompose by stirring a bacterial bed substrate (attached with a large amount of microorganisms). Because harmful substances such as salt and the like (which are not beneficial to the survival, growth and activity of microorganisms) exist in the kitchen waste, when the harmful substances are directly added into a fermentation tank (or) for carrying out microbial reaction due to overhigh content concentration, the living environment of the microorganisms can be seriously damaged, the growth, reproduction and decomposition of the microorganisms are extremely not beneficial, and the survival rate or the biological activity of the microorganisms are even seriously influenced, so that the problems of low decomposition efficiency, incomplete decomposition of the organic waste, odor, short service life of the microorganisms and the like are caused.

In the invention, when the small spiral blade segments 4-22 drive the organic garbage to rotate upwards and convey in the small-aperture section 4-13, as the organic garbage is at the upper port of the small-aperture section 4-13 outside the baffle disc 4-62, the baffle disc 4-62 can generate certain blocking force for the organic garbage in the small-aperture section 4-13, and further the organic garbage is extruded and conveyed to be further extruded and dehydrated when being rotated upwards and conveyed in the small-aperture section 4-13; meanwhile, the organic garbage can be dispersedly discharged into the microbial reaction chamber 5-1 from a plurality of gaps 4-63 (see figure 3). When the garbage which is too big (such as the slender garbage which is just vertically passed through the sieve holes of the sieve screen when being crushed and the slender garbage which is in the direction of the gap 4-63 is vertical and has the problem of being unable to be discharged) can not pass through the gap 4-63, the following garbage can be continuously conveyed and blocked, when the baffle disc 4-62 is pressed by a certain pressing force, the baffle disc 4-62 overcomes the acting force of the spring 4-5 and slides upwards on the upper end of the conveying shaft 4-2, the baffle disc 4-62 is far away from the small-aperture section 4-13 and leaves a discharging channel N (see figure 4) at the upper end, then the too big garbage of the gap 4-63 which can not pass through enters the microorganism reaction chamber 5-1 through the discharging channel N, the blockage can be avoided and the maintenance can be realized, and when the too big garbage of the gap 4-63 which can not pass through is discharged, the catch plate 4-62 is automatically returned to normal (as can be seen in connection with fig. 3-4) due to the spring force of the spring 4-5.

When the sliding shaft 4-7 moves outwards along with the outer cover sleeve 4-6, the large shaft section 4-71 compresses the spring 4-5 to store elastic potential energy; therefore, the spring 4-5 can elastically drive the sliding shaft 4-7 to move inwards under the action of the elastic potential energy during the reset, and the large shaft section 4-71 is stopped moving against the bottom surface of the internal thread counter bore 4-23, so that the automatic reset is realized.
Preferably, as can be seen in fig. 3-4, the notches 4-63 are progressively smaller in opening in a direction away from the minor diameter section 4-13 and progressively larger in distance from the center of the minor helical blade section 4-22.

The large shaft section 4-71 and the large hole section 4-41 can slide but can not rotate, and the outer cover sleeve 4-6 rotates along with the conveying shaft 4-2, so that garbage can be dispersed and thrown out from a plurality of gaps 4-63 and discharged into the microbial reaction chamber 5-1, the garbage is dispersed into the microbial reaction chamber 5-1, agglomeration can be reduced, and decomposition efficiency can be improved.
Referring to fig. 3-4, a sealing ring 4-8 is further arranged between the blind hole 4-61 and the side wall of the upper end of the conveying shaft 4-2. Because the outer cover sleeve 4-6 is sleeved on the upper end of the conveying shaft 4-2 through the blind hole 4-61, when the outer cover sleeve 4-6 axially slides on the upper end of the conveying shaft 4-2, the sealing ring 4-8 can prevent garbage, water and the like from entering the inner sleeve 4-4 through the blind hole 4-61, and can ensure the stability and reliability of the long-term work of the spring 4-5 and the sliding shaft 4-7.
The working process of the invention is as follows: referring to fig. 9, the organic waste is poured into a feeding hopper 1, the organic waste in the feeding hopper 1 enters a crushing chamber of a waste crushing mechanism 2 to be crushed and refined, the refined organic waste is subjected to cleaning, desalting and other treatment by a cleaning mechanism 3 and then enters a conveying cylinder 4-1 of a solid-liquid separation conveying mechanism 4 for secondary cleaning and solid-liquid separation, and the separated liquid waste flows into a waste liquid treatment system to be subjected to multistage treatment (oil-water separation, aerobic microbial decomposition, anaerobic microbial decomposition, purification and filtration in sequence) and then is discharged after reaching the standard; the separated solid garbage enters a microbial reaction chamber 5-1 of a solid garbage microbial decomposition mechanism 5 to be stirred for microbial decomposition, waste gas generated by decomposition of the microbial decomposition mechanism 5 is collected and treated to reach the standard and then is discharged, decomposed products generated by decomposition of the microbial decomposition mechanism 5 can be recycled as fertilizer, and decomposed water, undecomposed organic liquid and incompletely divided organic liquid and the like in the microbial decomposition mechanism 5 can be intensively input into a waste liquid treatment system to be treated in a centralized manner and then are discharged to reach the standard.
