Description

Technical Field

[0001] This utility model relates to the field of wastewater discharge devices, specifically a wastewater discharge device for marine aquaculture. Background Technology

[0002] Currently, the marine aquaculture industry is developing rapidly, but research on the treatment of marine aquaculture wastewater in China is still in its initial stage. It mainly focuses on some applied research on specific treatment projects. During the discharge of marine aquaculture wastewater, it is necessary to purify and filter the wastewater to reduce the risk of environmental pollution from wastewater discharge.

[0003] Existing technology discloses an integrated wastewater treatment device for marine aquaculture (authorization announcement number CN219194767U). This patented technology involves pouring the wastewater from marine aquaculture onto a filter screen for filtration. The filtered and settled water is then pumped by a second water pump and sent to a second treatment tank through a third connecting water pipe. Once the settled and filtered water is in the second treatment tank, it is aerated through a vent pipe, allowing gas to escape through the vent, promoting the exchange of substances between the gas and liquid, thus completing the purification. The purified water is then pumped by a third water pump through a fourth connecting water pipe to a third treatment tank. Meanwhile, a first water pump can extract medication from a medicine tank, which is then sent to the third treatment tank for treatment through a first connecting water pipe. The treated water is then pumped out by a fourth water pump and discharged through a second connecting test tube. The entire process is automated, requiring minimal manual operation and improving work efficiency.

[0004] However, existing external discharge devices filter effluent using only a single filter screen, resulting in weak filtration. Additionally, impurities tend to accumulate on the top of the filter plate, which is in initial contact with the effluent, even though the interior of the filter plate has not yet reached its full capacity. Frequent disassembly and cleaning of the filter plate can easily reduce the efficiency of the external discharge device. Utility Model Content

[0025] 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 scope of protection of the present utility model.

[0026] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0027] This application discloses a device for discharging wastewater from marine aquaculture. (Refer to...) Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A marine aquaculture wastewater discharge device includes a discharge box 1. The inner cavity of the discharge box 1 is provided with a first purification tank 9, a second purification tank 4, and a third purification tank 5. The inner cavities of the first purification tank 9 and the second purification tank 4 are connected, and the inner cavities of the second purification tank 4 and the third purification tank 5 are connected. An air vent pipe 8 is installed on the front side of the discharge box 1 and is connected to the inner cavity of the second purification tank 4. An discharge pipe 7 is installed on the right side of the discharge box 1 and is connected to the inner cavity of the third purification tank 5. A medicine box 6 is installed on the back side of the discharge box 1 and is connected to the inner cavity of the third purification tank 5. A filter mechanism 3 is installed in the inner cavity of the first purification tank 9. A scraping mechanism 2 is installed on the top of the discharge box 1.

[0028] The filtration mechanism 3 includes a guide groove 305 and a fixing frame 307. The guide groove 305 is respectively opened on both sides of the inner cavity of the first purification tank 9. The surface of the fixing frame 307 is movably connected to the inner cavity of the first purification tank 9. There are three fixing frames 307. The inner cavities of the three fixing frames 307 are respectively equipped with a first filter plate 301, a second filter plate 302 and a third filter plate 303 from top to bottom.

[0029] The scraping mechanism 2 includes a positioning frame 201. The bottom of the positioning frame 201 is movably connected to the top of the outer discharge box 1. A rotating wheel 209 is movably connected to the front side of the positioning frame 201. A lead screw 211 is fixedly connected to the back side of the rotating wheel 209. A movable plate 210 is threadedly connected to the surface of the lead screw 211. A scraper 202 is fixedly connected to the right side of the movable plate 210. The bottom of the scraper 202 is movably connected to the top of the first filter plate 301. A collection box 203 is fixedly connected to the inner side of the positioning frame 201.

[0030] Reference Figure 4 and Figure 5 Limiting grooves 208 are provided on both sides of the inner cavity of the positioning frame 201. A support plate 213 is fixedly connected to the right side of the scraper 202. The surfaces of the support plate 213 and the moving plate 210 are movably connected to the inner cavity of the limiting grooves 208. The movement of the scraper 202 is limited by the setting of the limiting grooves 208 to prevent the scraper 202 from moving too far, causing the scraper 202 to detach from the inside of the positioning frame 201 and affecting the subsequent normal reset of the scraper 202.

[0031] Reference Figure 4 and Figure 5 The inner cavity of the support plate 213 is movably connected to the support rod 212. The surface of the support rod 212 is fixedly connected to the inner cavity of the limiting groove 208. The support rod 212 guides the movement of the scraper 202, improves the stability of the scraper 202 during movement, and prevents the scraper 202 from getting stuck during movement.

[0032] Reference Figure 2 and Figure 3 The front and back sides of the inner cavity of the positioning frame 201 are movably connected to a first positioning rod 205 and a second positioning rod 207, respectively. A positioning ring 204 is threadedly connected to the surface of the first positioning rod 205. The bottom of the positioning ring 204 is movably connected to the top of the positioning frame 201. A positioning plate 206 is fixedly connected to the bottom of the second positioning rod 207. The top of the positioning plate 206 is movably connected to the bottom of the positioning frame 201. The positioning rods 205 and 207 are used to position the positioning frame 201, so that the positioning frame 201 can be stably attached to the top of the outer discharge box 1, preventing the positioning frame 201 from shifting during use. At the same time, the positioning ring 204 is used to fix the position of the positioning frame 201, preventing the positioning frame 201 from detaching from the surface of the first positioning rod 205. The positioning plate 206 is used to support the bottom of the positioning frame 201, so that the positioning frame 201 can operate more stably.

[0033] Reference Figure 2 , Figure 3 and Figure 6The two fixed frames 307 are fixedly connected to guide plates 308 on both sides, and one of the fixed frames 307 is fixedly connected to a fixed plate 311 on both sides. The surfaces of the guide plates 308 and the fixed plates 311 are movably connected to the inner cavity of the guide groove 305. The inner cavities of the guide plates 308 and the fixed plates 311 are movably connected to guide rods 304. The bottom of the guide rods 304 is fixedly connected to the bottom of the inner cavity of the guide groove 305. The guide rods 304 guide the movement of the fixed frames 307, prevent jamming during the installation and removal of the fixed frames 307, and improve the efficiency of the installation and removal of the fixed frames 307.

[0034] Reference Figure 2 and Figure 6 Both the guide plate 308 and the fixing plate 311 are movably connected to the surface of the filling plate 309. The inner cavity of the filling plate 309 is movably connected to the surface of the guide rod 304. The filling plate 309 supports the position of the fixing frame 307, prevents the fixing frame 307 from shifting during use, and can be used to position the fixing frame 307.

[0035] Reference Figure 3 and Figure 6 The inner cavity of the fixing plate 311 is provided with a fixing groove 310. An elastic block 306 is engaged in the inner cavity of the fixing groove 310. The bottom of the elastic block 306 is fixedly connected to the top of the outer discharge box 1. By setting the fixing groove 310, the elastic block 306 can be engaged into the interior of the fixing plate 311, thereby fixing the position of the fixing plate 311 and preventing the filling plate 309 inside the first purification tank 9 from shaking during use.

[0036] Working principle: The wastewater from seawater aquaculture that needs to be discharged is poured onto the surface of the first filter plate 301, where it undergoes initial filtration. The wastewater then comes into contact with the surface of the second filter plate 302. Because the pore size of the second filter plate 302 is smaller than that of the first filter plate 301, it achieves a secondary filtration effect. The wastewater then comes into contact with the surface of the third filter plate 303, which is made of activated carbon. The process involves collecting residual active chlorine and removing organic matter from the effluent, followed by three filtrations. The filtered effluent is then pumped into the second purification tank 4, where it is aerated via a vent pipe 8 to promote gas-liquid exchange and complete the treatment. The treated effluent is then pumped into the third purification tank 5, where chemicals are added via a chemical tank 6 to further purify the effluent. Finally, the purified effluent is discharged through an external drain pipe 7, where it undergoes initial filtration via a first filter plate 301. At this time, due to the large amount of impurities contained in the effluent, these impurities will accumulate on the top of the first filter plate 301. These impurities will affect the filtration efficiency of the first filter plate 301. However, since the first filter plate 301 has not yet reached its load capacity, frequent replacement of the first filter plate 301 will reduce the discharge efficiency of the effluent. At this time, the positioning frame 201 can be placed on the top of the discharge box 1, and the position of the positioning frame 201 can be positioned by the first positioning rod 205 and the positioning plate 206, so that the positioning frame 201 can be stably positioned. The filter plate is fixedly attached to the top of the outer discharge box 1. Then, the rotating wheel 209 can be rotated by holding it. The rotation of the rotating wheel 209 drives the lead screw 211 to rotate, which in turn drives the moving plate 210 to move. The movement of the moving plate 210 drives the scraper 202 to move on top of the first filter plate 301, pushing the impurities on top of the first filter plate 301 into the collection box 203 for collection. This can clean the impurities accumulated on top of the first filter plate 301 and prevent the need for frequent replacement of the first filter plate 301.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
