Description

Technical Field

[0001] This utility model belongs to the field of soil remediation fertilizer processing technology based on humic acid and microorganisms, and relates to a soil remediation fertilizer processing equipment based on humic acid and microorganisms. Background Technology

[0002] Humic acid has the functions of improving soil structure, enhancing fertilizer efficiency, and chelating heavy metals, making it an excellent soil remediation material. Functional microorganisms (such as nitrogen-fixing bacteria, phosphorus-solubilizing bacteria, and biocontrol bacteria) can directly participate in the soil ecological restoration process. Combining humic acid with functional microorganisms can exert a synergistic effect and significantly improve the soil remediation effect.

[0003] Chinese utility model patent CN222093171U discloses a humic acid water-soluble fertilizer mixing and processing equipment, including a mixing tank for mixing humic acid water-soluble fertilizer. The mixing tank includes a lower tank and an upper cover. A support is placed on the upper cover, and a fixed frame and a positioning rod extending into the lower tank are integrally connected to the support. A stirring component for stirring the humic acid water-soluble fertilizer is installed on the support, and a rotating component for rotating the support is installed on the fixed frame. This technical solution uses the output end of a telescopic rod to make the stirring... The mixing rod, traction rod, connecting rod one, and connecting rod two can be deployed. After being disconnected from the top cover by the fixing frame, the operator can easily clean the mixing components on the support. By dividing the mixing tank into an upper cover and a lower tank and connecting the upper cover and the lower tank with a limiting rod, it is more convenient for the operator to clean the mixing tank, thereby improving the cleanliness of the mixing tank. However, the above technical solution does not pre-treat the humic acid. The humic acid raw material may contain impurities, large particles, or carry bacteria, affecting the compounding effect and product quality stability. Utility Model Content

[0019] 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. Example

[0020] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, a soil remediation fertilizer processing device combining humic acid and microorganisms includes a shell 1. A discharge port 101 is provided on the lower side of the shell 1, and a third solenoid valve 13 is installed on the discharge port 101. A humic acid pretreatment structure communicating with the interior of the shell 1 is provided on the upper side of the shell 1. The humic acid pretreatment structure includes a pretreatment box 5 bolted to the upper side of the shell 1. A pulverizing chamber 501 and a sterilization chamber 502 are arranged vertically and vertically within the pretreatment box 5. The pulverizing chamber 501 is circular, and an opening is provided on its upper side. The pulverizing chamber 501 contains materials for pulverizing humic acid raw materials. The pulverizing assembly includes a filter screen 8 bolted between the pulverizing chamber 501 and the sterilization chamber 502. The filter screen 8 has an 80-mesh pore size, ensuring that the humic acid particles are ≤0.18mm in size, which facilitates subsequent mixing. Multiple UVC sterilization lamps 9 with a wavelength of 254nm are bolted into the sterilization chamber 502. A feed pipe connected to the inner cavity of the shell 1 is located on the lower side of the sterilization chamber 502, and a first solenoid valve 11 is installed on the feed pipe. A microbial assembly for conveying the microbial solution is also located on the upper side of the shell 1. (The feed pipe is fixedly connected to the shell and sterilization chamber by welding or flanges.)

[0021] The housing 1 is equipped with a stirring assembly for stirring humic acid and microbial solution.

[0022] During use, the operator pours the humic acid raw material into the grinding chamber 501 through the opening on the upper side of the pretreatment box 5. Under the action of the grinding components in the grinding chamber 501, the humic acid raw material is broken down into small particles that can pass through the filter screen 8. After the humic acid powder passes through the filter screen 8 and enters the sterilization chamber 502, it is irradiated by the UVC sterilization lamp 9 in the sterilization chamber 502 for 3 to 5 minutes. This kills the bacteria in the humic acid raw material without damaging the structure of the humic acid, providing a better growth environment for functional microorganisms and improving the purity and stability of the product. The UVC sterilization lamp achieves a bacterial kill rate of >99%, and when the humic acid particles are ≤80 mesh, the microbial adsorption efficiency is increased by 40%. Testing shows that at 254nm... UVC irradiation for 4 minutes can kill 99.2% of bacteria without affecting the activity of humic acid. Subsequently, the operator can control the first solenoid valve 11 to pour the sterilized humic acid raw material into the shell 1, where it comes into contact with the microbial solution transported into the shell 1 through the microbial component. Finally, under the action of the stirring component, the humic acid and the microbial solution are stirred and blended, and discharged through the discharge port 101 and the third solenoid valve 13 under the control of the operator. The pretreated humic acid can fully contact the microbial solution and reduce the number of bacteria inside, ensuring the purity and stability of the subsequent soil remediation fertilizer and improving the product quality of the soil remediation fertilizer.

[0023] In this embodiment, the pulverizing assembly includes a pulverizing shaft 6 rotatably connected to the pulverizing chamber 501 via bearings. Four pulverizing hammers 7 are mounted in a circular array on the circumferential side of the pulverizing shaft 6 via bolts. The pulverizing hammers 7 are in contact with the inner side of the pulverizing chamber 501. A rotating motor 10 is mounted on the front side of the pulverizing chamber via bolts. The output shaft of the rotating motor 10 is connected to the pulverizing shaft 6. In use, the rotating motor 10 can drive the pulverizing shaft 6 to rotate. When the pulverizing shaft 6 rotates, it can drive the pulverizing hammers 7 to break up the humic acid raw material, thereby reducing the particle size of the humic acid raw material, so that the humic acid can fully react with the microbial solution and ensure the production quality of the soil remediation fertilizer.

[0024] Example 2 differs from Example 1 in that:

[0025] like Figure 1 , Figure 2 As shown, the microbial component includes an insulated storage tank 14 bolted to the upper side of the shell 1. The insulated storage tank 14 is a 316L stainless steel insulated tank, which effectively improves the survival rate of microorganisms within it. The upper side of the insulated storage tank 14 is connected to an external delivery pipeline, and the lower end of the insulated storage tank 14 communicates with the inner cavity of the shell 1. A second solenoid valve 12 is installed at the connection between the insulated storage tank 14 and the shell 1. During use, the external pipeline can deliver the microbial solution to the insulated storage tank 14 for preservation, facilitating later use by staff and improving efficiency in the subsequent production and processing of soil remediation fertilizers. The use of a 316L stainless steel insulated storage tank 14 increases the microbial survival rate to 95%.

[0026] In this embodiment, the front side of the insulated liquid storage tank 14 is provided with a long strip-shaped observation window 141. A transparent insulation board is sealed inside the observation window 141. During use, the staff can observe the state and quantity of the microbial solution in the insulated liquid storage tank 14 through the transparent insulation board, which can help the staff effectively control the remaining amount of the microbial solution and prevent the microbial solution in the insulated liquid storage tank 14 from precipitating.

[0027] Example 3 differs from Example 1 in that:

[0028] like Figure 1As shown, the stirring assembly includes a stirring shaft 3 rotatably connected to the upper side of the inner cavity of the housing 1 via bearings. A stirring motor 2 is bolted to the upper side of the housing 1. The output shaft of the stirring motor 2 is connected to the end of the stirring shaft 3. Multiple stirring blades 4 are welded to the circumferential side of the stirring shaft 3. In use, the stirring motor 2 can drive the stirring shaft 3 to rotate the stirring blades 4, so that the stirring blades 4 can stir the humic acid raw material and the microbial solution in the housing 1, so that the humic acid raw material can fully react with the microbial solution and ensure the production and processing quality of the soil remediation fertilizer.

[0029] In this embodiment, a scraper 15 is welded to the end of the stirring blade 4 on the same side. The scraper 15 contacts the inner side of the shell 1. When in use, the scraper 15 can help the humic acid raw material and microbial solution adhere to the inner wall of the shell 1, which improves the convenience of subsequent cleaning of the shell 1 by the staff.

[0030] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
