Description

Technical Field

[0001] This utility model relates to the technical field of farmland drainage treatment, specifically to a farmland drainage ammonia reduction and phosphorus removal coupling device for disassembly. Background Technology

[0002] Ammonia nitrogen and phosphorus in farmland drainage are major causes of eutrophication, severely impacting the ecological environment. Traditional farmland drainage treatment methods often suffer from low efficiency, complex operation, and difficult maintenance, failing to meet the demands of modern agriculture for efficient, environmentally friendly, and convenient drainage treatment. In contrast, ammonia and phosphorus removal coupling devices for farmland drainage play a crucial role in the purification of farmland ecological water quality.

[0003] In response to this, CN221680929U proposed a coupling device for reducing ammonia and phosphorus in farmland drainage ditches. This utility model combines a planting base and a planting trough to achieve the functions of reducing ammonia and phosphorus, while also allowing for planting plants, placing decorations, covering fillers, and storing water, making the surface beautiful and ornamental.

[0004] However, the aforementioned technical solutions lack the disassembly and assembly function for the adsorption components in the coupling device during the ammonia and phosphorus removal process of farmland water. This prevents the device from quickly processing the adsorption components when they become saturated with ammonia and phosphorus impurities, affecting the purification efficiency and effectiveness of farmland water. While ordinary quick-disassembly ammonia and phosphorus removal devices have a quick-disassembly function, they cannot reinforce the adsorption components. Under prolonged water flow impact, the adsorption components are prone to floating, causing some water to flow out through the gap between the device and the water channel without being adsorbed, thus reducing the treatment quality of farmland drainage. In response, this design proposes a disassembly-compatible coupling device for ammonia and phosphorus removal in farmland drainage. Utility Model Content

[0005] The purpose of this invention is to provide a farmland drainage ammonia reduction and phosphorus removal coupling device for disassembly, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model proposes a disassembled farmland drainage ammonia and phosphorus removal coupling device, comprising a mounting base, a quick-release mounting mechanism mounted on the top of the mounting base, and a fixing component; the quick-release mounting mechanism includes three mounting brackets equidistantly installed in the inner wall of the mounting base, wherein two of the mounting brackets located at both ends have grooves on one side, and the two grooves are respectively opened towards the two ends of the mounting base; the top of each of the three mounting brackets has a mounting groove; both sides of each of the three mounting brackets have through grooves, and the inner walls at both ends of the three mounting grooves are respectively connected to the inner wall of one of the through grooves; a filter plate is installed on the inner wall of each through groove; a protective cover is installed on the top of the mounting base; a suspended solids adsorption plate, a total phosphorus adsorption plate, and an ammonia nitrogen adsorption plate are sequentially installed on the inner walls of the three mounting grooves from front to back; limiting brackets are fixed on both sides of the bottom of the protective cover, and the outer walls of the two limiting brackets are respectively connected to the inner walls of the two grooves, and the two limiting brackets are in an open state.

[0007] In one example, the fixing component includes mounting holes formed at both ends of the bottom of the inner wall of each through slot, with a limiting shaft inserted through the inner wall of each mounting hole, and the top of each limiting shaft being hemispherical.

[0008] In one example, a spring is fixedly provided at the bottom of each limiting shaft, and the bottom of each spring is fixedly connected to the bottom of the inner wall of each mounting hole. A first connecting hole is provided at the upper and lower ends of each filter plate, and one end of each limiting shaft is inserted and connected to the inner wall of the first connecting hole at the bottom of each filter plate.

[0009] In one example, each of the mounting brackets has a second connection hole on both sides of the mounting groove at the top, and a plurality of fixing pins are fixed at equal intervals at the bottom of the protective cover plate, and the outer wall of each fixing pin passes through the inner wall of each second connection hole and is inserted into the inner wall of the first connection hole located at the top of the filter plate.

[0010] In one example, handles are fixedly provided on both sides of the top of the protective cover, and two water-blocking strips are fixedly provided on both sides of the top of the mounting base at the edges of the top of the three mounting brackets.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting a quick-release installation mechanism, three mounting frames are installed in the mounting base during farmland drainage. Suspended solids adsorption plates, total phosphorus adsorption plates, and ammonia nitrogen adsorption plates are installed sequentially from front to back to treat the farmland drainage for ammonia and phosphorus removal. The protective cover plate with a limit bracket is inserted into the upper side to lock it in the grooves of the mounting frames at both ends. At the same time, filter plates are installed in the through slots on both sides of each mounting frame through fixed components to filter the flowing drainage. When replacing or cleaning each coupling adsorption plate or filter plate later, the protective cover plate is lifted directly, so that each adsorption plate loses its fixed obstruction and is easy to pull out and replace. At the same time, the filter plate also loses the reinforcement of the fixed components, making it easy to remove and clean. This solves the problem that the purification structure in the coupling device cannot be quickly replaced and the quick-release mechanism does not have a protective reinforcement function, which can easily cause the coupling structure to detach during long-term drainage.

[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.

[0020] Please see Figure 1-6 This utility model provides a technical solution: a farmland drainage ammonia reduction and phosphorus removal coupling device for disassembly, including a mounting base 1, a quick-release mounting mechanism 2 and a fixing component 3, all mounted on the top of the mounting base 1;

[0021] The quick-release installation mechanism 2 includes three mounting brackets 201 equidistantly installed in the inner wall of the mounting base 1. Two of the mounting brackets 201 located at both ends have grooves 202 on one side, with the two grooves 202 facing the two ends of the mounting base 1. Each of the three mounting brackets 201 has a mounting groove 203 on its top and through grooves 204 on both sides. The inner walls of each end of the three mounting grooves 203 communicate with the inner wall of one of the through grooves 204. A filter plate 205 is installed on the inner wall of each through groove 204. A protective cover plate 206 is installed on the top of the mounting base 1. Suspended solids adsorption plates 207 and total phosphorus adsorption plates are sequentially installed on the inner walls of the three mounting grooves 203 from front to back. The protective cover plate 206 has two fixed limiting brackets 210 on both sides of the bottom of the ammonia nitrogen adsorption plate 208 and the ammonia nitrogen adsorption plate 209. The outer walls of the two limiting brackets 210 are respectively inserted and connected to the inner walls of the two grooves 202. The two limiting brackets 210 are in the open state. The suspended matter adsorption plate 207 is made of perforated sponge, which can adsorb small particulate suspended matter without affecting the normal flow of drainage. The total phosphorus adsorption plate 208 is made of a mixture of activated carbon and zeolite. When the drainage flows through the mounting frame 201, the total phosphorus adsorption plate 208 can fully absorb phosphorus impurities. The ammonia nitrogen adsorption plate 209 is made of activated carbon and silica gel and other materials, which has a good adsorption effect on ammonia nitrogen mixture.

[0022] In use, the suspended solids adsorption plate 207, total phosphorus adsorption plate 208, and ammonia nitrogen adsorption plate 209 are respectively inserted into the mounting grooves 203 on the top of the three mounting frames 201. Then, according to the location of the drainage treatment, the entire mounting base 1 is installed in the designated position of the water ditch, and the gap between it and the water ditch is blocked with concrete or other building materials, so that the farmland drainage is discharged directly from the inner wall of the mounting base 1. After each adsorption plate is installed into the mounting groove 203 in the corresponding mounting frame 201 in sequence from front to back, since there are through grooves 204 on both sides of the mounting frame 201 that communicate with each mounting groove 203, the filter plate 205 is inserted into the through groove 204 and the limiting shaft 302 at the bottom of the through groove 204 is pressed. The filter plate 205 is fixed by the fixing component 3. Finally, the protective cover plate 206 is installed. The limiting bracket 210 at its bottom engages with the groove 202 on one side of the mounting brackets 201 at both ends. The inner wall of the groove 202 locks and presses the two limiting brackets 210 in place, so that the protective cover 206 can stably cover the top of the three mounting brackets 201 and block the area during coupling, preventing external dust from re-entering the treated drainage and causing secondary pollution. When the adsorption plate needs to be replaced later, the protective cover 206 can be lifted to release the limiting bracket 210 from the groove 202, exposing the adsorption plate installed in the mounting groove 203 on the top of each mounting bracket 201 for easy replacement. This design solves the problem that the purification structure in the coupling device cannot be quickly replaced and the quick-release mechanism does not have protective reinforcement function, which can easily cause the coupling structure to detach during long-term drainage.

[0023] Furthermore, the fixing component 3 includes mounting holes 301 at both ends of the bottom of the inner wall of each through groove 204. Each mounting hole 301 has a limiting shaft 302 inserted through its inner wall, and the top of each limiting shaft 302 is hemispherical. The mounting hole 301 is provided at the bottom of the inner wall of the through groove 204. The limiting shaft 302 is inserted through the mounting hole 301 by a spring 303. When installing the filter plate 205, a first connecting hole 304 is provided at the bottom of the filter plate 205, and the limiting shaft 302 can extend and retract in the mounting hole 301 under the extension and retraction of the spring 303, which facilitates the docking and fixing of the filter plate 205 with it.

[0024] Furthermore, each limiting shaft 302 is fixedly provided with a spring 303 at its bottom, and the bottom of each spring 303 is fixedly connected to the bottom of the inner wall of each mounting hole 301. Each filter plate 205 has a first connecting hole 304 at its upper and lower ends, and one end of each limiting shaft 302 is inserted and connected to the inner wall of the first connecting hole 304 at the bottom of each filter plate 205. When installing the filter plate 205, its bottom is pressed against the bottom of the inner wall of the through groove 204, so that the top of the inner wall of the first connecting hole 304 at its bottom is pressed against the top of the limiting shaft 302. The top of the limiting shaft 302 is hemispherical, which facilitates the buffering when the filter plate 205 is installed into the through groove 204 and is not prone to movement interference. At the same time, the limiting shaft 302 extends and retracts in the mounting hole 301 through the compression spring 303, which facilitates the insertion of the filter plate 205.

[0025] Each mounting bracket 201 has a second connecting hole 305 on both sides of the mounting groove 203 at its top. Multiple fixing pins 306 are fixedly fixed at equal intervals at the bottom of the protective cover 206. The outer wall of each fixing pin 306 passes through the inner wall of each second connecting hole 305 and is inserted into the inner wall of the first connecting hole 304 located at the top of the filter plate 205. After the filter plate 205 is inserted into the through groove 204, when the protective cover 206 is closed, the fixing pins 306 at its bottom directly pass through the second connecting holes 305 at the top of each mounting bracket 201 and insert into the top of each filter plate 205. The first connecting hole 304, together with the limiting shaft 302 at the bottom of the through groove 204, is inserted into the first connecting hole 304 at the bottom of the filter plate 205 to firmly fix the filter plate 205 on both sides of the mounting frame 201. The coupling structure is used to filter impurities in farmland drainage. When cleaning or replacement is required later, the protective cover plate 206 is lifted to disengage the fixing pin 306. The filter plate 205 is pulled out by force, and the limiting shaft 302 compresses the spring 303 in the mounting hole 301 to extend and retract, so that the filter plate 205 can be easily removed, which improves the convenience of replacement and disassembly of the coupling device in the later stage.

[0026] Furthermore, handles 4 are fixedly installed on both sides of the top edge of the protective cover 206. Two water-blocking strips 5 are fixedly installed on both sides of the top edge of the three mounting brackets 201. The sides of the water-blocking strips 5 can be made of waterproof soft materials, such as waterproof rubber. After the protective cover 206 is installed, the water-blocking strips 5 on both sides not only play a side water-blocking and sealing role, but also squeeze the protective cover 206 to fix it and prevent it from falling off due to excessive buoyancy during use. The handles 4 bear force when disassembling and assembling the protective cover 206, making the operation more labor-saving.
