Description

Technical Field

[0001] This utility model relates to the field of organic fertilizer fermentation tank technology, and in particular to a temperature-controlled fermentation tank for organic fertilizer production. Background Technology

[0002] With the deepening of the green transformation of agriculture, the market demand for organic fertilizer continues to rise due to its characteristics of improving soil and enhancing crop quality. Traditional organic fertilizer production methods, such as open-air composting or simple fermentation tanks, have many drawbacks and can no longer meet the needs of modern large-scale and standardized production.

[0003] The existing fermentation chambers do not have scraping devices on their inner walls. After the fermentation tanks have been used for a long time, some organic fertilizer will stick to the inner walls, which will prevent the heat from the outside from being exchanged well with the heat of the organic fertilizer inside the fermentation tank, thus affecting the fermentation efficiency of the organic fertilizer.

[0004] An existing patent (publication number: CN220766858U) discloses a temperature-controlled fermentation tank for organic fertilizer production, comprising an outer tank and an inner tank inside the outer tank. The top surface of the outer tank is provided with a cover plate, and the inner tank is provided with a stirring mechanism for stirring organic fertilizer. A temperature control mechanism for adjusting the internal temperature of the inner tank is provided between the outer tank and the inner tank. The stirring mechanism includes a stirring motor, the output end of which is provided with a rotating shaft. The surface of the rotating shaft is provided with a rotating frame, and scrapers are provided on both sides of the rotating frame. Stirring columns are evenly provided on the bottom surface of the rotating frame. When the rotating shaft rotates, the scrapers will continuously scrape the inner wall of the inner tank to prevent organic fertilizer from sticking to the inner wall of the inner tank, thereby improving the heat transfer efficiency of the fermentation tank and saving energy. Moreover, the evenly provided stirring columns on the top surface of the rotating frame can fully stir the organic fertilizer deposited at the bottom of the inner tank, thereby improving the fermentation efficiency of the organic fertilizer.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, existing fermentation tanks lack structures for treating the waste gases generated during the fermentation process. This results in the production of foul odors containing ammonia, hydrogen sulfide, methane, and other components during the organic fertilizer fermentation process. These odors not only have a strong, pungent smell but may also harm the human respiratory and nervous systems, thereby affecting the health of workers.

[0006] Therefore, a temperature-controlled fermentation tank for organic fertilizer production is proposed. Utility Model Content

[0007] The purpose of this invention is to provide a temperature-controlled fermentation tank for organic fertilizer production, which can solve the problem that existing organic fertilizer fermentation tanks lack a structure for treating the waste gas generated during the fermentation process. This results in the production of odorous gases containing ammonia, hydrogen sulfide, methane, and other components during the organic fertilizer fermentation process. These odorous gases not only have a strong pungent smell, but may also harm the human respiratory and nervous systems, thereby affecting the health of workers.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a temperature-controlled fermentation tank for organic fertilizer production, comprising a fermentation tank body, a support plate fixedly connected to the surface of the fermentation tank body, a spraying mechanism fixedly connected to the top of the support plate, and a pre-purification mechanism fixedly connected to the right side of the top of the support plate.

[0009] The spraying mechanism includes an exhaust pipe, a solenoid valve, a limiting shell, a water storage tank, a PLC controller, a spray plate, and a circulating pump. The exhaust pipe is fixedly connected to the top right side of the fermentation tank body. The solenoid valve is installed on the right side of the exhaust pipe. The limiting shell is fixedly connected to the top of the support plate. The right side of the solenoid valve passes through and is fixedly connected to the top left side of the limiting shell. The water storage tank is slidably connected to the bottom inside the limiting shell. The PLC controller is installed on the top front side of the limiting shell.

[0010] Preferably, the spray plate is fixedly connected to the top of the inner side of the limiting shell, the circulating pump is fixedly connected to the rear side of the top of the support plate, the front side of the circulating pump passes through the limiting shell and the water storage tank respectively and is snapped into the rear side of the inner side of the water storage tank, and the rear side of the circulating pump is fixedly connected to the top of the spray plate.

[0011] Preferably, the pre-purification mechanism includes a guide tube, a limiting box, a placement box, three sieve plates, and a connecting tube, with the left side of the guide tube fixedly connected to the top of the right side of the limiting shell.

[0012] Preferably, the limiting box is fixedly connected to the right side of the top of the support plate, the right side of the guide tube is fixedly connected to the bottom of the left side of the limiting box, and the placement box is slidably connected to the bottom of the inner side of the limiting box.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. The spraying mechanism of this application discharges the waste gas from the fermenter body through the exhaust pipe and controls the waste gas emission using a solenoid valve. The combination of the water storage tank, the circulating pump and the spray plate allows the water in the water storage tank to be transported to the spray plate for spraying, which performs preliminary washing of the waste gas. This removes some water-soluble or washable impurities, dust and some water-soluble harmful gases from the waste gas, thus playing a preliminary role in purifying the waste gas. The setting of the PLC controller enables the spraying mechanism to achieve intelligent control, and can automatically control the opening and closing of the solenoid valve and the operation of the circulating pump according to the set program, thereby improving the automation level of the equipment and the effectiveness of waste gas treatment.

[0019] 2. The pre-purification mechanism of this application places activated carbon granules in the box. The mesh-like sides of the granules allow the exhaust gas to pass through. The activated carbon granules adsorb and purify the exhaust gas, removing harmful substances and improving the purification effect. Three sieve plates allow for multiple filtration of the exhaust gas. Zeolite molecular sieves can use their regular microporous structure to sieve molecules in the exhaust gas, adsorbing molecules of specific sizes and properties. The activated carbon coating further increases the adsorption capacity for organic pollutants, odor molecules, etc. Attached Figure Description

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.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] A temperature-controlled fermentation tank for organic fertilizer production includes a fermentation tank body 1, a support plate 2 fixedly connected to the surface of the fermentation tank body 1, a spraying mechanism 3 fixedly connected to the top of the support plate 2, and a pre-purification mechanism 4 fixedly connected to the right side of the top of the support plate 2.

[0029] The spraying mechanism 3 includes an exhaust pipe 31, a solenoid valve 32, a limiting shell 33, a water storage tank 34, a PLC controller 35, a spray plate 36, and a circulating pump 37. The exhaust pipe 31 is fixedly connected to the top right side of the fermenter body 1. The solenoid valve 32 is installed on the right side of the exhaust pipe 31. The limiting shell 33 is fixedly connected to the top of the support plate 2. The right side of the solenoid valve 32 passes through and is fixedly connected to the top left side of the limiting shell 33. The water storage tank 34 is slidably connected to the bottom inside the limiting shell 33. The PLC controller 35 is installed on the top front side of the limiting shell 33.

[0030] In this embodiment: the fermentation tank body 1 provides a relatively enclosed space for the fermentation of organic materials, facilitating the control of parameters such as temperature and humidity during the fermentation process, ensuring that fermentation takes place in a suitable environment, which is beneficial to improving the fermentation quality and efficiency of organic fertilizer. The support plate 2 can support and limit the spraying mechanism 3 and the pre-purification mechanism 4. The exhaust pipe 31 can exhaust the waste gas generated in the fermentation tank body 1. The solenoid valve 32 can be opened or closed as needed through the command of the PLC controller 35 to adjust the discharge flow rate and time of the waste gas. The limiting shell 33 can... The system supports and limits the water storage tank 34, PLC controller 35, and spray plate 36. The water storage tank 34 can store washing liquid for spraying. The PLC controller 35 can automatically control the opening and closing of the solenoid valve 32 and the operation of the circulation pump 37 according to the preset program. The spray plate 36, together with the circulation pump 37, evenly sprays the washing liquid in the water storage tank 34 into the exhaust gas in the limiting shell 33, so that the water and exhaust gas can fully contact each other. The circulation pump 37 can draw the washing liquid in the water storage tank 34 and transport it to the spray plate 36 to realize the recycling of water and ensure the continuous operation of spraying.

[0031] Specifically, such as Figure 2 , Figure 3As shown, the spray plate 36 is fixedly connected to the top of the inner side of the limiting shell 33, the circulating pump 37 is fixedly connected to the rear side of the top of the support plate 2, the front side of the circulating pump 37 passes through the limiting shell 33 and the water storage tank 34 respectively and is snapped into the rear side of the inner side of the water storage tank 34, and the rear side of the circulating pump 37 is fixedly connected to the top of the spray plate 36.

[0032] Specifically, such as Figure 4 As shown, the pre-purification mechanism 4 includes a guide pipe 41, a limiting box 42, a placement box 43, three sieve plates 44 and a connecting pipe 45. The left side of the guide pipe 41 is fixedly connected to the top right side of the limiting shell 33.

[0033] Specifically, such as Figure 4 As shown, the limiting box 42 is fixedly connected to the right side of the top of the support plate 2, the right side of the guide tube 41 is fixedly connected to the bottom of the left side of the limiting box 42, and the placement box 43 is slidably connected to the bottom of the inner side of the limiting box 42.

[0034] In this embodiment: the exhaust gas after preliminary purification by spraying is guided to the limiting box 42 by the guide pipe 41. The limiting box 42 can support and limit the placement box 43, the sieve plate 44 and the connecting pipe 45. The two sides of the placement box 43 are set as filter screens, and the top of the placement box 43 is fixedly connected to the air outlet pipe, which guides the filtered exhaust gas to flow upward. The sieve plate 44 can perform multiple filtrations on the exhaust gas, which improves the purification degree of the exhaust gas and reduces the content of harmful substances in the exhaust gas. The connecting pipe 45 leads the exhaust gas after adsorption and purification by the placement box 43 out of the limiting box 42, providing a channel for the subsequent treatment or discharge of the exhaust gas.

[0035] Specifically, such as Figure 4 As shown, the sieve plate 44 is slidably connected to the inside of the limiting box 42, and the connecting pipe 45 is fixedly connected to the rear side of the top of the placement box 43.

[0036] Specifically, such as Figure 5 As shown, the two sides of the placement box 43 are made into a filter mesh, and activated carbon particles 5 are placed inside the placement box 43.

[0037] In this embodiment: by setting the two sides of the placement box 43 as a filter mesh, the exhaust gas can enter the inner side of the placement box 43. By setting the activated carbon particles 5, which have a rich microporous structure and a large specific surface area, they have a strong adsorption capacity for organic pollutants, odor molecules, etc. in the exhaust gas, and can effectively remove harmful substances in the exhaust gas, further purifying the exhaust gas.

[0038] Specifically, such as Figure 5 As shown, sieve plate 44 is a zeolite molecular sieve, and the surface of sieve plate 44 is coated with an activated carbon coating.

[0039] Specifically, such as Figure 5As shown, both the water storage tank 34 and the placement box 43 are fixedly connected to the front side with handles 6, and the surface of the handles 6 is engraved with anti-slip texture.

[0040] In this embodiment: by setting the sieve plate 44 as a zeolite molecular sieve, the regular microporous structure of the zeolite molecular sieve can sieve the molecules in the exhaust gas and selectively adsorb specific molecules according to the size and properties of the molecules. By setting an activated carbon coating, the adsorption capacity for organic pollutants, odor molecules, etc. is further enhanced. By setting a handle 6, it is convenient for users to operate the water storage tank 34 and the placement box 43. By setting an anti-slip texture, the friction between the hand and the handle 6 can be increased.

[0041] Working principle: First, the user installs the fermentation tank body 1 into the pre-selected working position. Next, the user adds the organic fertilizer raw materials to be fermented to the inside of the fermentation tank body 1. Then, the user pulls the water storage tank 34 out from the bottom inside the limiting shell 33 using the handle 6 on the front side of the water storage tank 34. Based on the composition and properties of the waste gas, a suitable washing liquid is selected and added to the inside of the water storage tank 34. After the washing liquid is added, the user holds the handle 6 again to return the water storage tank 34 to the limiting shell 33. Once the preparation work is complete, the user starts the fermentation tank body 1. Body 1 begins fermenting the organic fertilizer raw materials inside. During the fermentation process, waste gas containing various harmful substances is generated. At this time, the PLC controller 35 controls the opening of the solenoid valve 32 and the circulation pump 37 according to the user's preset program and parameters. When the solenoid valve 32 opens, the waste gas generated during fermentation enters the inner side of the limiting shell 33 through the exhaust pipe 31. At the same time, the circulation pump 37 starts, extracts and pressurizes the washing liquid inside the water storage tank 34, and then delivers it to the spray plate 36. The spray plate 36 sprays the washing liquid downward in a fine water mist, which interacts with the upper... The sprayed washing liquid fully contacts the exhaust gas, achieving initial purification. Due to gravity, the sprayed washing liquid falls downwards and returns to the inside of the storage tank 34, realizing the recycling of the washing liquid. After initial purification, the exhaust gas enters the bottom of the limiting box 42 through the guide pipe 41. The exhaust gas then enters the inside of the placement box 43 through both sides. The placement box 43 is filled with a large amount of activated carbon particles 5. When the exhaust gas comes into contact with the activated carbon particles 5, harmful substances are rapidly adsorbed, achieving further deep purification of the exhaust gas. The exhaust gas purified by the activated carbon particles 5 continues to... The exhaust gas flows upward through the outlet pipe at the top of the placement box 43 and passes sequentially through the three sieve plates 44 inside the limiting box 42. The sieve plates 44 sieve the molecules in the exhaust gas. Through the multiple filtration and adsorption effects of the three sieve plates 44, the exhaust gas is finally pre-treated, and the content of harmful substances is greatly reduced. Finally, the user connects the external purification equipment to the connecting pipe 45. The pre-purified exhaust gas smoothly enters the external purification equipment through the connecting pipe 45 for further deep purification treatment until it meets the national environmental protection emission standards, and is finally safely discharged into the external environment.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
