Description

Technical Field

[0001] The utility model relates to the technical field of sludge treatment, in particular to a sludge airflow membrane composting fermentation system. Background Art

[0002] Sludge is the solid sediment produced by sewage treatment plants during the sewage purification process. It is a complex of various colloids, organic matter, adsorbed metal elements, microorganisms, pathogens, insect eggs, etc. Sludge aerobic composting technology refers to the process of converting organic matter in sludge into fertilizer under artificial control conditions by using the physiological and biochemical activities of microorganisms to achieve harmless, reduced and resourceful treatment of sludge.

[0003] However, a large amount of foul-smelling gases are often released during the composting process, and the main components of the odor are ammonia (NH3), hydrogen sulfide (H2S) and volatile organic compounds (VOC). Since sludge composting fermentation belongs to aerobic composting technology, the compost is usually still exposed to the air. The large amount of odor produced by the composting will cause secondary pollution to the environment, and the heat energy loss is serious, resulting in a long fermentation cycle and unsatisfactory composting effect.

[0004] According to the search, the Chinese utility model patent with patent number CN202122982594.9 discloses a sludge airflow membrane composting device. According to the analysis of the device, by placing the pretreated pile into a polymer semipermeable membrane, the overflow of odorous macromolecules can be avoided and the external environment can be ensured. However, since the internal pile needs to be turned over during the composting process, the polymer semipermeable membrane is easily broken during the turning process, and after the composting is completed, the polymer semipermeable membrane needs to be spread out to facilitate the removal of the internal pile, which may also cause damage to the polymer semipermeable membrane. Utility Model Content

[0005] Therefore, in order to solve the above-mentioned shortcomings, the utility model provides a sludge airflow membrane composting fermentation system. The fermentation system can conveniently put in the pile for aerobic fermentation through a fermentation barrel arranged on a support body. At the same time, the fermentation diaphragm movably arranged on the support body can contact with the top of the fermentation barrel, thereby preventing the macromolecular gas in the fermentation barrel from overflowing outward, ensuring the processing environment, and facilitating the opening of the fermentation diaphragm to facilitate the stirring or removal of the pile inside the fermentation barrel. In this way, not only the fermentation diaphragm is protected, but also the odor is prevented from overflowing during the composting process.

[0006] The utility model is realized by constructing a sludge airflow membrane composting fermentation system, comprising a support body, on the top of which a plurality of evenly distributed fermentation barrels are placed and gas can be passed into the fermentation barrels;

[0007] The fermentation diaphragm is movably arranged on one side of the support body and keeps in contact with and separated from the top of the fermentation barrel. When the fermentation diaphragm contacts the top of the fermentation barrel, it can isolate the flow of macromolecular gases inside and outside the fermentation barrel.

[0008] Specifically, several parallel and equally spaced placement grooves are formed on the support body. The fermentation barrels are placed side by side in these placement grooves. A support rod is arranged on the outside of any end of the support body close to the placement groove. One end of the fermentation diaphragm is wound around the outside of the support rod and can rotate. Several clamping rods are arranged on the outside of the other end of the support body close to the placement groove. The number of the clamping rods is the same as that of the placement grooves and their positions correspond to each other.

[0009] Specifically, there are multiple fermentation diaphragms, which respectively correspond to the placement grooves on the support body. One end of the fermentation diaphragm is set as a rotating part sleeved on the outer end of the support rod, and the other end of the fermentation diaphragm is set as a connecting part that can be inserted into the clamping rod and clamped. When the clamping rod passes through the connecting part, the fermentation diaphragm is kept in contact with the top of the fermentation barrel.

[0010] Specifically, the width of the fermentation diaphragm is greater than the width of the fermentation barrel. An outwardly extending protrusion is arranged on the outer side of the top of the fermentation barrel. A hook-and-loop fastener A surface is arranged on the outer side surface of the protrusion. Hook-and-loop fastener B surfaces are arranged on both sides of the fermentation diaphragm. When the fermentation diaphragm is in contact with the top of the fermentation barrel, the hook-and-loop fastener B surface of the fermentation diaphragm can be connected to the hook-and-loop fastener A surface on the outside of the protrusion.

[0011] Specifically, the fermentation diaphragm is made of polytetrafluoroethylene material.

[0012] Specifically, the fermentation diaphragm is a porous microfilm formed by expansion and stretching.

[0013] The utility model has the following beneficial effects:

[0014] The fermentation system can facilitate the aerobic fermentation after putting in the compost by the fermentation barrels arranged on the support body. At the same time, the fermentation diaphragm movably arranged on the support body can contact the top of the fermentation barrel, thereby preventing the macromolecular gases in the fermentation barrel from overflowing outward, ensuring the processing environment, and at the same time facilitating the lifting of the fermentation diaphragm to facilitate the stirring or taking out of the compost inside the fermentation barrel. In this way, not only the fermentation diaphragm is protected, but also the odor overflow during the composting process is prevented. Description of the Drawings

Any modification of the structure, change of the proportional relationship or adjustment of the size, without affecting the effects that the present utility model can produce and the purposes that can be achieved, should still fall within the scope that can be covered by the technical content disclosed in the present utility model.

[0025] As described in the background technology, since the static compost is exposed to the air, a large amount of odors generated by the compost will cause secondary pollution to the environment, and the heat energy loss is serious, resulting in a long fermentation cycle and an unsatisfactory composting effect.

[0026] In a part of the sludge composting device, the composting materials are placed inside a polymer semi-permeable membrane. Since the composting materials need to be turned and fermented, the membrane may be damaged during the turning process. Moreover, when taking out the composting materials, the membrane needs to be fully opened, which is likely to cause damage to the membrane during the removal process.

[0027] For the above reasons, please refer to the attached Figure 1 - attached Figure 4 drawings, the present utility model provides a sludge air-flow membrane composting and fermenting system, including a support body 1, on the top of which several evenly distributed fermentation barrels 2 are placed and gas can be introduced into the fermentation barrels 2.

[0028] A fermentation diaphragm 3 is movably arranged on one side of the support body 1 and is in contact with and separated from the top of the fermentation barrel 2. When the fermentation diaphragm 3 is in contact with the top of the fermentation barrel 2, it can isolate the flow of macromolecular gases inside and outside the fermentation barrel 2.

[0029] Please refer carefully to the attached Figure 2 drawings. Specifically, several mutually parallel and equally spaced placement grooves 1.2 are formed on the support body 1, and the fermentation barrels 2 are placed side by side in the placement grooves 1.2. On the outer side of any one end of the support body 1 close to the placement grooves 1.2, a support rod 1.3 is arranged. One end of the fermentation diaphragm 3 is wound around the outer side of the support rod 1.3 and can rotate. On the outer side of the other end of the support body 1 close to the placement grooves 1.2, several clamping rods 1.1 are arranged. The number of the clamping rods 1.1 is the same as the number of the placement grooves 1.2 and they are in corresponding positions.

[0030] According to the above paragraph, setting the placement grooves can facilitate the stable placement of the fermentation barrels and prevent the fermentation barrels from moving randomly during the turning process.

[0031] Please refer to the attached Figure 2 drawing and the attached Figure 5 drawing. Specifically, there are multiple fermentation diaphragms 3, which are respectively in corresponding positions with the placement grooves 1.2 on the support body 1. One end of the fermentation diaphragm 3 is set as a rotating part 3.1 sleeved on the outer end of the support rod 1.3, and the other end of the fermentation diaphragm 3 is set as a connecting part 3.3 that can be inserted into the clamping rod 1.1 and clamped. When the clamping rod 1.1 passes through the connecting part 3.3, the fermentation diaphragm 3 is kept in contact with the top of the fermentation barrel 2.

[0032] According to the above paragraph, setting the rotating part on the fermentation diaphragm is to facilitate one end to be connected to one side of the support body and keep it rotatable. Setting the connecting part at the other end of the fermentation diaphragm is to facilitate the connection with the clamping rod on the other side of the support body, so that the fermentation diaphragm is in contact with the top of the fermentation barrel and prevent the leakage of macromolecular gases.

[0033] Please refer to the attached Figure 3 drawing, the attached Figure 5 drawing and the attached Figure 6, specifically, the width of the fermentation diaphragm 3 is greater than the width of the fermentation barrel 2. An outwardly extending protrusion 2.1 is provided on the outer side of the top of the fermentation barrel 2, and a hook surface 2.2 of a magic tape is provided on the outer side surface of the protrusion 2.1. Magic tape loop surfaces 3.2 are provided on both sides of the fermentation diaphragm 3. When the fermentation diaphragm 3 is attached to the top of the fermentation barrel 2, the magic tape loop surfaces 3.2 of the fermentation diaphragm 3 can be connected to the hook surface 2.2 of the magic tape on the outside of the protrusion 2.1.

[0034] As described in the previous paragraph, setting the width of the fermentation diaphragm and the magic tape on both sides ensures that when the fermentation diaphragm is attached to the top of the fermentation barrel, both sides thereof can contact and be fixed to the protrusions on the side surface of the fermentation barrel, effectively preventing the escape of large molecule gases and enhancing the sealing performance.

[0035] , specifically, the fermentation diaphragm 3 is made of polytetrafluoroethylene material.

[0036] , specifically, the fermentation diaphragm 3 is a porous microfilm formed by expansion and stretching.

[0037] During the use of this compost fermentation system, first separate the connecting portion 3.3 of the fermentation diaphragm 3 from the clamping rod 1.1, rotate the fermentation diaphragm 3 to the outside of the support body 1, then place the fermentation barrel 2 into the placement groove 1.2, pour the pretreated compost material into the fermentation barrel 2, and then rotate the fermentation diaphragm 3 to fit with the top of the fermentation barrel 2. Fix it by inserting the clamping rod 1.1 into the connecting portion 3.3 of the fermentation diaphragm 3. Finally, connect the magic tape loop surfaces 3.2 on both sides of the fermentation diaphragm 3 to the hook surface 2.2 of the magic tape on the fermentation barrel 2, so that the fermentation diaphragm 3 is closely attached to the top of the fermentation barrel 2 to prevent the escape of large molecule gases. Oxygen can be introduced into the interior through the holes that communicate with each other between the side surface of the support body 1 and the placement groove 1.2 and the holes on the side surface of the fermentation barrel 2 (as can be seen from Attachment Figure 1 and Attachment Figure 6 ) to achieve compost fermentation.

[0038] The above description is a detailed description of the preferred and feasible embodiments of the present invention, but the embodiments are not intended to limit the scope of the patent application of the present invention. Any equivalent changes or modifications made under the technical spirit disclosed by the present invention shall fall within the scope of the patent covered by the present invention.
