Description

Technical Field

[0001] The present invention relates to the technical field of excrement treatment, and in particular to a system and process for reducing harm and improving the quality of pig excrement. Background Art

[0002] It is of great significance to carry out technical research on pig manure pollution control and resource recycling, and composting is a technical means to achieve harmless treatment and resource utilization of pig manure.

[0003] Worm manure is a method of growing earthworms in specific nutrients (such as cow dung, pig dung, mud piles, etc.) to reproduce in large quantities and produce a large amount of feces. The feces of earthworms contain a large number of beneficial bacteria, which can be used to ferment animal feces. Therefore, mixing earthworm manure with traditional animal feces for fermentation is a practical composting method. However, it is precisely because earthworm manure contains a large number of bacteria that (1) it is difficult to monitor the fermentation conditions in various parts of the mixture during fermentation (different bacteria are enriched in different places, which easily leads to different fermentation conditions in different places); (2) earthworm manure and pig manure are both solids, and it is difficult to truly mix them fully during mixing, so it is easy to cause uneven distribution of colonies, and it is also difficult to detect the actual fermentation conditions of each part when sampling the fermented product; (3) the fermentation process will produce a certain amount of moisture, making the pig manure more viscous. At this time, if a regulator is added during the fermentation, it is also difficult to fully mix the entire fermented product. Therefore, it is necessary to design a more efficient and scientific pig manure fermentation process. Summary of the invention

[0004] The object of the present invention is to provide a system and process for reducing harm and improving the quality of pig manure, which can efficiently utilize earthworm manure to reduce harm and improve the quality of pig manure.

[0005] The embodiments of the present invention are realized through the following technical scheme: the pig manure harm reduction and quality improvement system of the present invention includes a fermentation tank, a plurality of grooves arranged at the bottom of the fermentation tank, a bottom plate with a porous structure laid on the bottom of the fermentation tank, a plurality of through holes opened on the bottom plate, a sleeve detachably connected to the through holes and arranged above the bottom plate, a sampling tube slidably arranged in the sleeve, and a negative pressure device connected to the sampling tube; one of the through holes is arranged directly above one of the grooves.

[0007] Furthermore, the connecting pipe is arranged on the lower surface of the bottom plate.

[0008] Furthermore, a drainage hole is provided at the bottom of the groove, and a drainage device is provided at the lower end of the drainage hole.

[0009] Furthermore, the drainage device includes a drainage pipe arranged below the drainage hole, a plug arranged inside the drainage pipe, and a spring arranged below the plug; the inner diameter of the drainage pipe is larger than the diameter of the plug, and the diameter of the plug is larger than the diameter of the drainage hole.

[0010] Furthermore, the diameter of the lower end of the sampling tube is smaller than the diameter of the drainage hole, and a sampling hole is provided on the side wall of the sampling tube.

[0015] (3) During the fermentation of the first mixture in the fermentation tank, the sampling tube is inserted into the sleeve so that the lower end of the sampling tube extends into the interior of the groove, and the liquid in the groove is sucked by the negative pressure device and the sampling tube, and the liquid is tested for bacterial species and pH, and the pH, temperature and humidity, and ventilation intensity are adjusted according to the test results;

[0016] (4) adding plant fiber powder, lime powder, potassium dihydrogen phosphate, urea, and Bacillus subtilis powder to the first mixture and mixing them uniformly to obtain a second mixture; in terms of mass fractions, the first mixture comprises 100 parts, plant fiber powder 100 parts, lime powder 10 parts, potassium dihydrogen phosphate 10 parts, urea 5 parts, and Bacillus subtilis powder 1 part;

[0017] (5) During the fermentation of the second mixture, the sampling tube is inserted into the sleeve and extended into the groove, the liquid in the groove is sucked by the negative pressure device, the liquid is tested for bacterial species and pH, and the pH, temperature and humidity, and ventilation intensity are adjusted according to the test results;

[0018] (6) At the end of the fermentation of the second mixture, the sampling tube is inserted into the sleeve and the two are sealed, and then the negative pressure device is started to continuously suck the sampling tube and the groove to extract excess water in the groove and the second mixture;

[0019] (7) After all the water in the second mixture is extracted, all the casings are removed and the second mixture is then discharged.
