Description

Technical Field

[0001] This invention relates to the field of wastewater treatment equipment, and more particularly to a grassland ecological restoration device and method. Background Technology

[0002] With rapid industrialization and urbanization, water pollution has become increasingly severe, posing a serious threat to the ecological environment and human health. In the field of wastewater treatment, biological treatment technology has been widely used due to its high efficiency and environmental friendliness. Ecological rope packing is a key component of biological treatment technology, commonly used in biofilm processes in wastewater treatment. It provides a carrier for microorganisms to attach and grow, allowing them to form a biofilm on its surface. When wastewater flows through the ecological rope packing, organic pollutants, ammonia nitrogen, and other harmful substances are degraded and transformed by the microorganisms in the biofilm, thereby achieving water purification.

[0003] However, traditional ecological rope filler processing equipment has many drawbacks. On the one hand, the production process has a low degree of automation, relying heavily on manual operation to complete the rope winding process. This not only results in low production efficiency but also makes it difficult to ensure the stability and consistency of product quality, easily leading to problems such as loose winding and dimensional deviations. On the other hand, traditional equipment has limited functionality, only capable of performing simple winding actions and unable to further treat the surface of the ecological rope filler. This makes the surface of the ecological rope filler relatively smooth, making it difficult for water to fully penetrate its internal pores, affecting the contact efficiency between microorganisms and pollutants, and thus reducing the wastewater treatment effect. In addition, during the winding process, the filler material is difficult to evenly wrap inside the ecological rope filler, resulting in uneven filler distribution and failing to fully utilize its function, thus limiting the ecological rope filler's ability to treat pollutants.

[0004] Therefore, it is necessary to provide a grassland ecological restoration device and method to solve the above-mentioned technical problems. Summary of the Invention

[0016] Compared with related technologies, the grassland ecological restoration device and method provided by the present invention have the following beneficial effects: This invention provides a grassland ecological restoration device and method. When the driver is running, it drives the second gear to rotate via the drive rod, causing the ecological rope to wind evenly within the winding groove. During the winding process, the ecological rope gradually wraps around the filler material. Simultaneously, as the second gear continues to rotate, the first bevel gear also synchronously drives the two second bevel gears to rotate. These two bevel gears, through the transmission wheel, drive the two connecting rods to rotate in opposite directions. The rotation of the connecting rods causes the rotating wheel to rotate synchronously, causing the wound ecological rope, now formed as a single unit, to slide to the right under the synchronous pressure of the upper and lower extrusion plates. At the same time, the wound ecological rope enters the extrusion hole and slides outward under the continuous pressure of the two extrusion plates on the left. At this point, the clip inside the extrusion hole... The teeth tightly engage with the surface of the ecological rope to prevent slippage during pushing, ensuring a continuous and stable discharge speed. After the ecological rope completely detaches from the extrusion hole, a composite ecological rope with a uniform filler distribution is formed. This composite ecological rope is moved out of the device by the conveyor belt, completing the processing. During the processing, the device wraps the filler material inside the biological rope filler, making the filler material more evenly distributed within the biological rope filler. This avoids local accumulation or missing filler material, ensuring the consistency of the overall performance of the biological rope filler and enabling it to function stably in the sewage treatment process. At the same time, the device integrates the winding, deburring, and filler material wrapping processes into one machine, realizing integrated processing of the biological rope filler.

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Please refer to the following: Figures 1 to 8 The grassland ecological restoration device and method include: a processing mechanism 1 and an extrusion mechanism 2, wherein the extrusion mechanism 2 is disposed within the processing mechanism 1; Processing mechanism 1 includes a base 11, a housing assembly 12 located above the base 11, a recycling assembly 13 connected to the housing assembly 12, a discharge hole 14 disposed on one side of the housing assembly 12, a driver 15, and a conveyor plate 16, wherein the conveyor plate 16 is disposed inside the housing assembly 12, and the driver 15 is connected to the housing assembly 12.

The discharge component 24 is snapped into the protective component 21. The protective component 21 is fixedly connected inside the outer shell component 12.

[0022] The outer casing assembly 12 includes a protective shell 121. A feed hole 122 is provided on one side of the protective shell 121.

The lower part of the protective shell 121 is fixedly connected to the machine base 11. The inner wall of the protective shell 121 is fixedly connected to the conveyor plate 16. A discharge hole 14 is provided on the other side of the protective shell 121. The driver 15 is fixedly connected to the protective shell 121. The recycling assembly 13 includes a recycling cover 131. A recycling cylinder 132 is fixedly connected to the lower part of the recycling cover 131. The recycling cylinder 132 and... The circulating pump 133 is connected to the discharge hood 135 via the conveying pipe 134. The recovery cylinder 132 and the circulating pump 133 are both fixedly connected to the lower part of the inner wall of the protective shell 121. The recovery hood 131 is located below the conveying plate 16. The circulating pump 133 is used to recover the packing material collected by the recovery hood 131 and transport it again to the conveying plate 16 along the conduit and the discharge hood 135. Since this device integrates multiple functions, compared with the traditional production method that requires multiple devices to complete different processes, it reduces the number of devices and the floor space, thereby reducing the purchase cost of equipment and the site rental cost.

[0023] The protective assembly 21 includes a connecting shell 211, with two side plates 212 fixedly connected to the lower part of the connecting shell 211. There are four side plates 212, each fixedly connected to one side of the inner wall of the protective shell 121. The side plates 212 are respectively engaged with the transmission assembly 22 and the discharge assembly 24. The transmission assembly 22 includes a first gear 221, with a first bevel gear 222 fixedly connected to one side of the first gear 221 and a drive rod 223 fixedly connected to the other side. The first bevel gear 222 meshes with two second bevel gears 224, and the two second bevel gears 224 are respectively fixedly connected to two rotators 225. The rotating device 225 includes a bearing and a shaft. The drive rod 223 passes through the protective shell 121 and is connected to the driver 15. The two rotating devices 225 are respectively engaged with the two side plates 212 located above. The two drive wheels 25 are respectively fixedly connected to the outside of the two rotating devices 225. After the two ecological ropes are placed inside the device, they can automatically wind them and directly discharge the wound biological rope filler, realizing the automation of the production process. This greatly reduces the manual operation links, reduces labor intensity, improves production efficiency, and also reduces the impact of human factors on product quality, ensuring the stability of product quality.

[0024] The winding assembly 23 includes a second gear 231. A sleeve 232 is engaged with one side of the second gear 231. Two winding grooves 233 are formed on one side of the second gear 231. An extrusion hole 235 is formed between the two winding grooves 233. The diameter of the extrusion hole 235 is larger than the diameter of the winding groove 233. A rubber pad 234 is fixedly connected inside the winding groove 233. Several retaining teeth 236 are fixedly connected to the inner wall of the extrusion hole 235. The second gear 231 meshes with the first gear 221. 232 is snapped into one side of the inner wall of the protective shell 121. Because it is provided with two winding grooves 233 and one extrusion hole 235, and the diameter of the winding grooves 233 is smaller than that of the extrusion hole 235, it is ensured that when the two ecological ropes are initially wound, the two ecological ropes can be stably snapped into the winding grooves 233. As the second gear 231 rotates, the winding of the ecological ropes is completed. As the two ecological ropes are wound into one strand, their diameter gradually increases and they are smoothly discharged through the extrusion hole 235, ensuring the stability of the device during use. Because of the rubber pad 234 and the locking teeth 236, the rubber pad 234 can effectively increase the friction between the ecological rope and the second gear 231, thereby ensuring the winding effect of the ecological rope. The locking teeth 236 can effectively guide and limit the ecological rope when it passes through the extrusion hole 235. At the same time, as the ecological rope is discharged along the locking teeth 236, the locking teeth 236 can effectively insert holes and continuously cut open the surface of the ecological rope, so that the surface of the ecological rope forms a uniformly distributed perforated structure during the discharge process, which improves the contact efficiency between the ecological rope processed by the device and the pollutants, thereby improving the sewage treatment effect. Because several teeth 236 are provided in the extrusion hole 235, the friction between the extrusion hole 235 and the ecological rope is ensured, and the ecological rope is prevented from slipping when it enters the extrusion hole 235 along the winding groove 233 due to its small diameter, thus ensuring the winding effect of the device on the ecological rope. The discharge assembly 24 includes a connecting rod 241, a sleeve 242 is sleeved on the connecting rod 241, a rotating wheel 243 is fixedly connected to the connecting rod 241, two elastic telescopic rods 244 are fixedly connected to the rotating wheel 243, the other ends of the two elastic telescopic rods 244 are fixedly connected to a pressing plate 245, a number of friction blocks 246 are fixedly connected to the pressing plate 245, the connecting rod 241 is connected to one of the rotators 225 through a transmission wheel 25, and the sleeve 242 is snapped into one side of the side plate 212.

[0025] The working principle of the grassland ecological restoration device and method provided by this invention is as follows: When in use, insert two unprocessed ecological ropes along both sides of the isolation plate 123 into the protective shell 121, and insert them into the two winding grooves 233 in the second gear 231 along the conveyor plate 16. At this time, the circulation pump 133 can be started to transport the filler material in the recycling cylinder 132 along the guide tube and the discharge hood 135 to the conveyor plate 16, and then the driver 15 is started. When the driver 15 is running, it drives the second gear 231 to rotate via the drive rod 223, causing the eco-rope to wind evenly within the winding groove 233. During the winding process, the eco-rope gradually wraps around the filler material. Simultaneously, as the second gear 231 continues to rotate, the first bevel gear 222 also synchronously drives the two second bevel gears 224 to rotate. These two bevel gears 224, through the transmission wheel 25, drive the two connecting rods 241 to rotate in opposite directions. The rotation of the connecting rods 241 causes the rotating wheel 243 to rotate synchronously, thus ensuring even winding. The ecological rope, which is then formed into a single unit, slides to the right under the synchronous extrusion of the upper and lower extrusion plates 245. At the same time, the wound ecological rope enters the extrusion hole 235 and slides outward under the continuous extrusion of the two extrusion plates 245 on the left. At this time, the locking teeth 236 in the extrusion hole 235 tightly engage with the surface of the ecological rope to prevent it from slipping during the pushing process and to ensure a continuous and stable discharge speed. After the ecological rope is completely separated from the extrusion hole 235, a composite ecological rope with uniform filler distribution is formed. The composite ecological rope is moved out of the device with the conveyor belt, and the processing is completed. During the processing, as the ecological rope moves to the right along with the two extrusion plates 245, the filler continuously falls into the recovery hood 131 along the conveying plate 16. At this time, the circulation pump 133 will continuously transport the collected filler back to the top of the conveying plate 16 along the conduit 134 and the discharge hood 135 to ensure sufficient filler.

[0026] Compared with related technologies, the grassland ecological restoration device and method provided by the present invention have the following beneficial effects: Because of the rubber pad 234 and the locking teeth 236, the rubber pad 234 can effectively increase the friction between the ecological rope and the second gear 231, thereby ensuring the winding effect of the ecological rope. The locking teeth 236 can effectively guide and limit the ecological rope when it passes through the extrusion hole 235. At the same time, as the ecological rope is discharged along the locking teeth 236, the locking teeth 236 can effectively insert holes and continuously cut open the surface of the ecological rope, so that the surface of the ecological rope forms a uniformly distributed perforated structure during the discharge process, which improves the contact efficiency between the ecological rope processed by the device and the pollutants, thereby improving the sewage treatment effect. The device automatically winds two ecological ropes inside the equipment and discharges the wound biological rope filler directly, thus automating the production process. This greatly reduces manual operation, lowers labor intensity, and improves production efficiency. At the same time, it also reduces the impact of human factors on product quality and ensures product quality stability.
