Description

Technical Field

[0001] This utility model relates to the field of nutrient soil processing technology, specifically to an air supply structure and an ecological nutrient soil processing system. Background Technology

[0002] Sludge is the main raw material for processing nutrient soil. After microwave pyrolysis, the organic matter inside the sludge is partially decomposed. To further improve the quality of the nutrient soil, biological fermentation is also required. Biological fermentation is a biochemical process that relies on microbial activity. A sufficient oxygen supply is a necessary condition for the normal growth and reproduction of microorganisms, and it is also a key factor in the full fermentation of sludge and the improvement of nutrient soil quality.

[0003] In traditional sludge fermentation processes, oxygen supply is often uneven, leading to unsatisfactory fermentation results. In some areas, insufficient oxygen may inhibit microbial activity, thus affecting the degree of sludge fermentation and the final quality of the nutrient soil. Utility Model Content

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0042] Example 1:

[0043] like Figures 1 to 3 As shown, this utility model provides an air supply structure, mainly including a fermentation tank 1, an air distribution baffle 2, and an air permeability component 4. The fermentation tank 1 is used for biological fermentation of nutrient soil. An air inlet 11 is located at the center of the bottom of the fermentation tank 1, and a positioning step 12 is formed on the bottom side wall of the fermentation tank 1. The air distribution baffle 2 is supported on the positioning step 12. Two symmetrical planes are milled on the lower part of the outer wall of the fermentation tank 1, opposite to the positioning step 12. Positioning holes 13, which are threaded holes, are formed on these planes and connect to the positioning step 12. Positioning bolts 14 are threaded into the positioning holes 13, and the two positioning bolts 14 are distributed at 180°. After tightening the positioning bolts 14, the inner ends of the two positioning bolts 14 abut against the circumferential surface of the air distribution baffle 2, thus positioning the air distribution baffle 2. A positioning groove is formed on the circumferential surface of the air distribution baffle 2, and the inner ends of the positioning bolts 14 are engaged in the positioning groove, effectively improving the stability of the air distribution baffle 2 in the fermentation tank 1.

[0044] The gas distribution baffle 2 is a certain distance from the bottom of the fermentation tank 1, forming a gas distribution cavity 3 between the gas distribution baffle 2 and the bottom of the fermentation tank 1. The gas distribution baffle 2 has evenly distributed mounting holes 21, which penetrate the gas distribution baffle 2 in the thickness direction. A groove is formed on the lower side of the gas distribution baffle 2, and a support plate 5 is welded and fixed in the groove. The support plate 5 has evenly distributed ventilation holes 51, which penetrate the support plate 5 in the thickness direction. In this embodiment, the ventilation holes 51 correspond one-to-one with the mounting holes 21, the diameter of the ventilation holes 51 is smaller than the diameter of the mounting holes 21, and the ventilation holes 51 and mounting holes 21 are arranged coaxially. A ventilation component 4 is installed in each mounting hole 21. During operation, external gas enters the gas distribution cavity 3 through the air inlet 11, and then provides oxygen to the fermentation process in the fermentation tank 1 through the ventilation holes 51 and the ventilation component 4.

[0045] Example 2:

[0046] Based on the above embodiment one, as follows Figures 3 to 5 As shown, this utility model provides a breathable component 4, which includes a conical seat 41, a breathable sponge 42, a filter screen 43 and a protective net 44 installed sequentially from bottom to top into the mounting hole 21.

[0047] The lower end face of the conical seat 41 is flat, and the conical seat 41 is supported on the support plate 5. A conical groove is opened at the upper end of the conical seat 41, and the center of the groove extends to the center of the lower end face of the conical seat 41, so that the center of the conical seat 41 forms a connecting hole 411. The connecting hole 411 is coaxially opposite to the vent hole 51 on the support plate 5, forming a connecting channel. The bottom of the groove of the conical seat 41 has evenly distributed strip grooves 412, which facilitates the rapid and even distribution of airflow throughout the groove. The lower end of the breathable sponge 42 is conical and is installed in the groove of the conical seat 41. The upper end face of the breathable sponge 42 is flat. The filter screen 43 covers the breathable sponge 42. The protective net 44 presses on the filter screen 43 to position the conical seat 41, the breathable sponge 42 and the filter screen 43. In this embodiment, the protective net 44 has a raised locking strip 441 around its periphery, and a locking groove 211 is provided on the inner wall of the upper port of the mounting hole 21. When the protective net 44 is pressed down from the upper port of the mounting hole 21, the locking strip 441 is fitted into the locking groove 211 by the deformation of the protective net 44.

[0048] During operation, the airflow in the air distribution chamber 3 passes through the air vents 51 and enters the air-permeable sponge 42. It then enters the periphery of the air-permeable sponge 42 through the evenly distributed strip grooves 412, and finally passes out from the top of the air sponge 42, forming a relatively evenly distributed upward airflow on the air distribution baffle 2, providing sufficient oxygen for the fermentation process in the fermentation tank 1.

[0049] Example 3:

[0050] Based on the above embodiment two, as follows Figures 1 to 6As shown, this utility model provides an ecological nutrient soil processing system. A row of bases 61 is set in a fermentation chamber 6, with an air supply pipe 62 passing through the bases 61. Evenly distributed air supply seats 621 are installed on the bases 61, connecting to the air supply pipe 62. A controllable electromagnetic valve is installed in each air supply seat 621. A slide rail 63 is fixed to the top of the fermentation chamber 6, vertically opposite to the bases 61. A crane 64 is slidably mounted on the slide rail 63, allowing the fermentation tank 1 to be transferred. During operation, the crane 64 lifts the fermentation tank 1 onto the bases 61. The air inlet 11 at the lower end of the fermentation tank 1 connects to the air supply seat 621. When the electromagnetic valve is turned on, gas at a certain pressure is introduced into the air distribution chamber 3 via the air supply seat 621. The airflow enters the fermentation tank 1 along the vent 51 and the venting component 4, providing oxygen for the fermentation process.
