Abstract
Description
Technical Field
[0001] This utility model relates to the field of soil degradation technology, and in particular to a microbial enhanced degradation reactor for organic polluted soil. Background Technology
[0002] Microbial degradation of organically contaminated soil is a process that uses the metabolic activities of microorganisms to transform organic pollutants in the soil into harmless or low-toxic substances. Degradation is usually carried out through reactors. This technology has become a research hotspot in the field of soil remediation due to its low cost, environmental friendliness, and strong sustainability.
[0003] During microbial degradation, the contaminated soil is first excavated from the contaminated site and crushed to increase the surface area of soil particles, facilitating subsequent contact with microorganisms and nutrients. The crushed soil is then screened to remove large particles (such as stones and plant roots). Afterward, the soil slurry is thoroughly mixed with microorganisms and nutrients through mechanical stirring or air lifting in the reactor to improve mass transfer efficiency.
[0004] However, existing degradation reactors can only stir the soil during the degradation of organic polluted soil, which has low functionality. They cannot turn the soil at the bottom during stirring, thus affecting the degradation effect. Therefore, we propose a novel microbial enhanced degradation reactor for organic polluted soil. Utility Model Content
[0005] The purpose of this invention is to solve the problem that existing degradation reactors in the prior art can only stir and degrade organic polluted soil, resulting in low functionality and the inability to turn over the soil at the bottom during stirring, thus affecting the soil degradation effect.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a microbial enhanced degradation reactor for organic polluted soil, comprising a reactor body, wherein an enhanced stirring assembly is provided inside the reactor body, the enhanced stirring assembly includes a stirring rod, both sides of the stirring rod having slots, springs being provided inside the slots, a push plate being connected to one side of the springs, a scraper being connected to one side of the push plate, a connecting cover being connected to the bottom surface of the stirring rod, a first helical gear being connected to the stirring rod inside the connecting cover, a set of second helical gears being connected to both sides of the first helical gears, a flipping plate being connected to one side of the second helical gears, and through holes being arrayed inside the flipping plate.
[0007] Furthermore, the pusher plate and the spring form an elastic structure, and the outer surface of the scraper is in contact with the inner wall of the reactor body. The elastic structure can push the scraper to stick to the inner wall of the reactor body, and while stirring, it can clean the soil on the inner wall.
[0008] Furthermore, the position and size of the first helical gear are matched with the position and size of the two sets of second flat gears, and the first helical gear and the second flat gear form a meshing connection, so that the two sets of flipping plates can simultaneously turn over the soil at the bottom.
[0009] Furthermore, a crushing assembly is connected to the top of one side of the reactor body. The crushing assembly includes a feed inlet, and a motor is connected to one side of the feed inlet. The crushing assembly can easily crush the soil again.
[0010] Furthermore, the output end of the motor is connected to a first crushing rod, one side of the first crushing rod is connected to a first spur gear, and the front surface of the first spur gear is connected to a second spur gear, which can drive the second spur gear to rotate.
[0011] Furthermore, a second crushing rod is connected to one side of the second spur gear. The first spur gear meshes with the second spur gear, and the meshing connection allows both sets of crushing rods to rotate inward simultaneously, thereby crushing the soil.
[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0013] 1. In this utility model, when decomposing soil, the stirring rod can be activated to stir the soil, and the bottom flipping plate will also flip the bottom soil under the action of the stirring rod, thereby improving the soil degradation effect.
[0014] 2. In this invention, after the soil is poured into the reactor body, the first crushing rod and the second crushing rod will crush the soil again, thus avoiding the problem of easy blockage of the reactor body. Attached Figure Description

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0023] Examples, such as Figure 1 - Figure 5 As shown, this utility model provides a microbial enhanced degradation reactor for organic polluted soil, including a reactor body 1. An enhanced stirring assembly 2 is installed inside the reactor body 1. The enhanced stirring assembly 2 includes a stirring rod 201. Grooves 202 are opened on both sides of the stirring rod 201. A spring 203 is installed inside the groove 202. A push plate 204 is connected to one side of the spring 203, and a scraper 205 is connected to one side of the push plate 204. A connecting cover 206 is connected to the bottom surface of the stirring rod 201. A first helical gear 207 is connected to the stirring rod 201 inside the connecting cover 206. A set of second helical gears 208 are connected to both sides of the first helical gear 207. A flipping plate 209 is connected to one side of the second helical gear 208. Through holes 210 are arrayed inside the flipping plate 209.
[0024] like Figure 2 As shown, the pusher plate 204 and the spring 203 form an elastic structure. The outer surface of the scraper 205 is in contact with the inner wall of the reactor body 1. The elastic structure can push the scraper 205 to stick to the inner wall of the reactor body 1. While stirring, it can clean the soil on the inner wall.
[0025] like Figure 2 and Figure 3 The position and size of the first helical gear 207 are matched with the position and size of the two sets of second flat gears 305. The first helical gear 207 and the second flat gear 305 form a meshing connection, and the two sets of flipping plates 209 simultaneously turn over the soil at the bottom through the meshing connection.
[0026] like Figure 4 As shown, a crushing component 3 is connected to the top of one side of the reactor body 1. The crushing component 3 includes a feed inlet 301, and a motor 302 is connected to one side of the feed inlet 301. The crushing component 3 can easily crush the soil again.
[0027] like Figure 1 and Figure 4 As shown, the output end of the motor 302 is connected to a first crushing rod 303, a first spur gear 304 is connected to one side of the first crushing rod 303, and a second spur gear 305 is connected to the front surface of the first spur gear 304. The first spur gear 304 can drive the second spur gear 305 to rotate.
[0028] like Figure 4 As shown, a second crushing rod 306 is connected to one side of the second spur gear 305. The first spur gear 304 meshes with the second spur gear 305. Through the meshing connection, the two sets of crushing rods can rotate inward at the same time to crush the soil.
[0029] The overall effect of this embodiment is as follows: When degrading organically polluted soil microorganisms, soil can be poured into the reactor body 1, and then the reactor body 1 can be started to degrade the soil microorganisms. The degradation of soil microorganisms by the reactor body 1 is a prior art and will not be described in detail here. When the reactor body 1 is started, it will also drive the stirring rod 201 to rotate. When the stirring rod 201 rotates, the spring 203 will also push the push plate 204 to drive the scraper 205 to stick tightly to the inner wall of the reactor body 1 through its own elasticity, thereby cleaning the inner wall. At the same time, the stirring rod 201 will also drive the first helical gear 207 to rotate, thereby making the first helical gear 207 rotate. 07 can simultaneously mesh and rotate with two sets of second helical gears 208, allowing the second helical gears 208 to drive the tilting plate 209 to rotate and also tilt, effectively enhancing the soil degradation effect. When soil is poured into the feed inlet 301, the motor 302 can be turned on to drive the first crushing rod 303 to rotate, which in turn drives the first flat gear 304 to rotate. This allows the first flat gear 304 to mesh and rotate with the second flat gear 305, thereby driving the second crushing rod 306 and the first crushing rod 303 to rotate inward simultaneously, achieving soil crushing and avoiding the problem of easy clogging of the reactor body 1.
[0030] Working principle: When decomposing the soil, the stirring rod 201 is activated to stir the soil. The bottom flipping plate 209 will also flip the soil at the bottom under the action of the stirring rod 201, which improves the soil degradation effect. When the soil is poured into the reactor body 1, the first crushing rod 303 and the second crushing rod 306 will crush the soil again to avoid the problem of easy blockage of the reactor body 1.
[0031] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
