Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, specifically to an air conditioner for a marine grain storage compartment. Background Technology

[0002] Ships specifically designed for transporting bulk cargo are typically equipped with grain storage tanks to carry bulk grains such as wheat, corn, and soybeans. These tanks have relatively simple structures and large spaces, capable of accommodating large quantities of grain. During grain transport, the complex and variable marine environment, with significant fluctuations in temperature and humidity, makes it difficult to maintain a stable temperature and humidity environment for grain storage using only natural ventilation. Air conditioning units can actively regulate the temperature and humidity within the tanks, ensuring stable grain storage conditions.

[0003] In existing technologies, marine grain storage tank air conditioners recirculate air by returning air from inside the storage tank to the air conditioner through return air vents, mixing it with outside air, and then processing it again. However, grain continuously respires during storage, and its free moisture is slowly released into the air through transpiration. For some high-moisture grains, the amount of moisture released is more significant. This means that the air entering the air conditioner from the storage tank carries a large amount of moisture. As this moisture accumulates, it can cause the air conditioner's filters to become damp, affecting air filtration efficiency. It also creates a humid environment inside the air conditioner, promoting bacterial growth and increasing the risk of grain mold, which is detrimental to grain storage.

[0004] Therefore, we propose a marine grain storage compartment air conditioner to address the problems mentioned in the background section. Summary of the Invention

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. In use, the air in the storage compartment enters the horn tube through the first switching pipe, impacting the outer surface of the conical shroud. Water vapor is impacted and dispersed outside the shroud, condensing into small water droplets. Simultaneously, the tip of the conical shroud breaks the airflow, forcing it to flow along the inclined plane, increasing the contact opportunity between water vapor and the outer surface of the shroud, causing more water vapor to gather together. After being discharged through the exhaust pipe, the air flows along the inner wall of the spherical shroud, impacting the outer surface of the rolled shroud again. Residual water vapor in the air adheres to the outer surface of the rolled shroud, forming water droplets again, achieving secondary separation of air and water vapor, significantly reducing air humidity. Through the special shape and structure of the conical and rolled shrouds, water vapor in the air is doubly separated, preventing water vapor from entering the air conditioner with the air and affecting subsequent air filtration.

[0020] 2. In use, the separated air enters the flexible hose through the outlet pipe and connecting pipe. Multiple jet pipes then spray the air onto the activated carbon adsorption bed, adsorbing harmful gases and improving air purity. Activating the forward and reverse motors drives the rotating rod and long gear to rotate, causing two sets of gears to move in opposite directions, pushing the first moving plate upwards and the second moving plate downwards. The first rack drives the flat gear to rotate, driving one set of jet pipes to converge towards the center; simultaneously, the second rack drives the flat gear to rotate in the opposite direction, driving two sets of jet pipes to open outwards. Driven by the forward and reverse motors, the first and second sets of jet pipes maintain an alternating convergence and opening pattern, allowing the discharged air to form a more uniform and comprehensive airflow coverage on the activated carbon adsorption bed, improving the adsorption and removal rate of harmful gases.

[0021] 3. In use, when the first humidity sensor or gas sensor detects abnormal humidity data or harmful gas content, the PLC controller closes the two first electric valves and opens the two second electric valves, allowing air to enter the water vapor separation component and gas processing component for processing through the first switching pipe. When the humidity or harmful gas content is within the normal range, the PLC controller closes the two second electric valves and opens the two first electric valves, allowing air to directly enter the air conditioner body through the return air duct. The intelligent switching component can switch the return air delivery path. When the air in the storage compartment is normal, the air directly enters the air conditioner body, improving operating efficiency. When the air is abnormal, it separates water vapor and adsorbs harmful gases, improving air purity.

[0022] 4. In use, the liquid storage cover is filled with a modified activated carbon-superabsorbent resin composite material, which simultaneously absorbs water and adsorbs harmful gases. This prevents accidental air leakage and inhalation of harmful gases by staff when the liquid storage cover is removed and the internal composite material is replaced. A second humidity sensor detects the humidity of the processed air. When the humidity is abnormal, it indicates that the composite material in the liquid storage cover is about to become saturated and needs to be replaced promptly. Attached Figure Description

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Example 1: Please refer to Figures 1-12 As shown, the present invention provides a technical solution: an air conditioner for a marine grain storage compartment, comprising an air conditioner body 1, an intelligent switching component 2 fixedly connected to the top of the air conditioner body 1, a water vapor separation component 3 fixedly installed inside the intelligent switching component 2, and a gas treatment component 4 disposed inside the water vapor separation component 3; the intelligent switching component 2 includes an upper separation shell 203, a middle separation shell 204 bolted to the bottom of the upper separation shell 203, and a lower separation shell 205 bolted to the bottom of the middle separation shell 204; the water vapor separation component 3 includes a spherical cover 301, the spherical... Inside the shroud 301, a horn tube 302 is installed. Inside the horn tube 302, a conical shroud 303 is installed. A liquid collecting ring 305 is fixedly connected to the bottom of the horn tube 302 and the bottom of the conical shroud 303. A first liquid permeable membrane 306 is fixedly connected to the inner wall of the liquid collecting ring 305. Inside the conical shroud 303, a roll-up shroud 308 is fixedly installed. Multiple air outlet pipes 309 are fixedly connected to the outer surface of the roll-up shroud 308. Multiple liquid outlet holes 310 are opened on the inner wall of the spherical shroud 301. A second liquid permeable membrane 311 is fixedly connected to the bottom of the spherical shroud 301 by bolts. The system includes a liquid storage hood 312, the interior of which is filled with absorbent composite material. Multiple drain pipes 315 are fixedly connected to the bottom of the liquid collection ring 305. A first sealing gasket 313 is fixedly connected to the top surface of the inner wall of the liquid storage hood 312, and a second sealing gasket 314 is fixedly connected to the bottom surface of the inner wall of the liquid storage hood 312. Multiple vent pipes 307 are fixedly connected to the bottom of the outer surface of the horn tube 302. The bottom ends of the multiple drain pipes 315 are all fixedly connected through the spherical cover 301 and the second permeable membrane 311 to the interior of the liquid storage hood 312. The bottom ends of the multiple vent pipes 309 are all fixedly connected through the roll-up cover 308 to... At the bottom of the spherical cover 301, the outer surfaces of the first sealing gasket 313 and the second sealing gasket 314 are both in contact with the inner wall of the spherical cover 301. A fixing rod 304 is fixedly installed on the top surface inside the conical cover 303. The bottom end of the fixing rod 304 is fixedly installed at the center of the inner wall of the spherical cover 301. The outer surface of the spherical cover 301 is fixedly installed on the inner wall of the upper separation shell 203. The top of the horn tube 302 is fixedly installed on the top surface inside the upper separation shell 203. The fixing rod 304 is located inside the roll-type cover 308. The bottom of the roll-type cover 308 is fixedly installed on the inner wall of the spherical cover 301.

[0039] In this embodiment, during use, air from the storage compartment enters the horn tube 302 through the first switching pipe 202. The conical shroud 303 is located at the center of the horn tube 302. As the air flows downward, it directly impacts the outer surface of the conical shroud 303. The impact causes water vapor in the air to adhere to the outer surface of the conical shroud 303, and as the amount of water vapor adheres increases, it gradually gathers into small water droplets. At the same time, the tip of the conical shroud 303 breaks through the incoming air, forcing the impacted air to flow along the inclined surface of the conical shroud 303, increasing the contact opportunity between water vapor and the outer surface of the conical shroud 303, thus causing more water vapor to gather together. Under the action of the conical shroud 303, the air undergoes initial water vapor separation. Both the first liquid-permeable membrane 306 and the second liquid-permeable membrane 311 are made of polytetrafluoroethylene microporous membranes, allowing water droplets to pass through, but making it difficult for air to pass through. At the same time, the polytetrafluoroethylene microporous membrane has good impact resistance and can withstand the impact of airflow. Water droplets on the outer surface of the conical cover 303 enter the collection ring 305 through the first liquid-permeable membrane 306 and then enter the storage cover 312 through multiple drain pipes 315. The air after water vapor separation is discharged through the exhaust pipe 307 and flows towards the center along the spherical inner wall of the spherical cover 301, impacting the outer roll of the roll-shaped cover 308. Residual water vapor in the air collides with the outer surface of the roll-shaped cover 308 and forms water droplets again, achieving the purpose of secondary separation of air and water vapor and greatly reducing the humidity of the air. Then, the air continues to flow along the roll-shaped path of the roll-shaped cover 308 and flows downward through multiple air outlet pipes 309, while the water droplets on the outer surface of the roll-shaped cover 308 flow to the bottom area under the action of gravity and pass through the second liquid-permeable membrane 311 through multiple liquid outlet holes 310 into the storage cover 312. The water vapor separation component 3 performs dual separation of water vapor in the air, preventing water vapor from entering the air conditioner with the air and affecting the subsequent air filtration effect. This solves the problem that when grain in the ship's grain storage tank releases water vapor into the air during storage, it then enters the air conditioner for air circulation. As more and more water vapor accumulates in the air conditioner, it can easily cause the filter in the air conditioner to become damp, affecting the air filtration effect. It can also easily lead to the growth of bacteria inside the air conditioner, exacerbating the risk of grain mold and hindering grain storage.

[0040] Furthermore, the liquid storage cover 312 is filled with a modified activated carbon-superabsorbent resin composite material. When separated water enters the liquid storage cover 312, it is absorbed by the superabsorbent resin portion of the composite material, while the modified activated carbon portion can absorb harmful gas molecules carried by a small amount of air that may accidentally seep in. This simultaneously achieves the functions of absorbing water and adsorbing harmful gases, preventing the accidental infiltration of air and the inhalation of harmful gases by personnel when the liquid storage cover 312 is removed and the internal composite material is replaced. When clean air processed by the gas treatment component 4 is discharged, the humidity in the air is detected by the second humidity sensor 214. When the humidity is abnormal, it indicates that the composite material in the liquid storage cover 312 is about to be saturated and needs to be replaced in time.

[0041] Example 2: Figure 3 and Figures 7-12As shown, an intelligent switching component 2 is fixedly connected to the top of the air conditioner body 1. A water vapor separation component 3 is fixedly installed inside the intelligent switching component 2. A gas treatment component 4 is installed inside the water vapor separation component 3. The gas treatment component 4 includes a fixing plate 401, inside which eight connecting pipes 403 are fixedly installed. An activated carbon adsorption bed 402 is installed inside the lower separation housing 205. Movable hoses 404 are fixedly connected to the bottom ends of the eight connecting pipes 403. Jet pipes 405 are fixedly connected to the bottom ends of the eight movable hoses 404. Rotating rings 417 are fixedly installed on the outer surfaces of the eight jet pipes 405. Two rotating columns 418 are fixedly installed on the outer surfaces of the eight rotating rings 417. Multiple rotating columns 418... All outer surfaces are fixedly mounted with flat gears 419. A first movable plate 408 and a second movable plate 409 are movably embedded between the outer surfaces of the eight movable hoses 404. A gear rack 410 is fixedly mounted on the bottom of the first movable plate 408 and the top of the second movable plate 409. A long gear 411 meshes with the opposite side of the two gear racks 410. A rotating rod 412 is fixedly mounted inside the long gear 411. A forward and reverse motor 413 is provided on one outer surface of the long gear 411. Eight first racks 420 are fixedly mounted at the bottom edge of the first movable plate 408, and eight second racks 421 are fixedly mounted at the bottom edge of the second movable plate 409. The outer surfaces of the multiple first racks 420 and the multiple second racks 421... The outer surfaces are respectively meshed with the outer surfaces of multiple flat gears 419. Sealing rings 407 are fixedly connected to the inner walls of the top ends of eight connecting pipes 403. The bottom ends of multiple air outlet pipes 309 are respectively fitted to the inner walls of multiple sealing rings 407. The output end of the forward / reverse motor 413 is fixedly connected to one end of the rotating rod 412. A fixing bracket 423 is fixedly installed on the outer surface of the forward / reverse motor 413. A mounting plate 422 is movably sleeved on the other end of the rotating rod 412. Two moving holes 414 are opened on the top of the first moving plate 408. Two support rods 416 are movably embedded inside the two gear racks 410. Moving holes 415 are opened on the tops of the first moving plate 408 and the second moving plate 409. The inner wall of the middle separation housing 204 is fixed... Eight V-shaped plates 406 are fixedly installed. The top of the fixing frame 423 and the top of the mounting plate 422 are both fixedly installed on the top surface inside the fixing plate 401. The outer surfaces of the fixing frame 423 and the mounting plate 422 are respectively movably embedded in the interior of two moving holes 414. The top ends of four support rods 416 are all fixedly installed on the top surface inside the fixing plate 401. The top ends of two support rods 416 are movably inserted to the top of the first moving plate 408, and the bottom ends of the other two support rods 416 are movably inserted to the bottom of the second moving plate 409. The outer surfaces of two toothed racks 410 are respectively movably embedded in the interior of two moving holes 415. One end of multiple rotating columns 418 is respectively movably embedded on the outer surfaces of both sides of the eight V-shaped plates 406.

[0042] In this embodiment, during use, the internal structure of the sealing ring 407 is Y-shaped, wider at the top, narrower in the middle, and cylindrical at the bottom. The bottom end of the air outlet pipe 309 enters the middle through the wider opening at the top. Because the middle and lower parts of the sealing ring 407 are narrower, the bottom end of the air outlet pipe 309 will spread the middle and lower parts of the sealing ring 407 apart. Through the special design of the sealing ring 407, the air outlet pipe 309 and the sealing ring 407 are in close contact, greatly improving the sealing performance. After the water vapor separation component 3 separates the water vapor in the air, the air enters multiple movable hoses 404 through the air outlet pipe 309 and the connecting pipe 403, and is sprayed downwards by multiple jet pipes 405. Then, it passes through the activated carbon adsorption bed 402, which adsorbs harmful gases in the air, improving the purity of the air. The forward and reverse motor 413 is activated, driving the rotating rod 412 to rotate the long gear 411, which in turn drives the two gear racks 410 to move in opposite directions. One of the gear racks 410 moves upward, pushing the first moving plate 408 upward on the outer surface of the fixed frame 423, mounting plate 422, and support rod 416, and driving multiple first racks 420 to move upward. The eight jet pipes 405 are evenly divided into two groups, with the two groups of jet pipes 405 distributed at intervals. One group of jet pipes 405 corresponds to the first rack 420 and the first moving plate 408, and the other group of jet pipes 405 corresponds to the second rack 421 and the second moving plate 409. As the first rack 420 moves upward, it drives the corresponding flat gear 419 to rotate, which in turn drives a set of jet pipes 405 to rotate in a converging manner through the flip ring 417. At the same time, another rack 410 moves downward, pushing the second moving plate 409 and the second rack 421 to move downward, which drives the corresponding flat gear 419 to rotate (in the opposite direction to the rotation of the flat gear 419 corresponding to the set of jet pipes 405), which in turn drives the two sets of jet pipes 405 to rotate outward through the flip ring 417. Next, the output of the forward and reverse motor 413 rotates in opposite directions, driving the first and second sets of jet pipes 405 to rotate and reset. Then, the output of the forward and reverse motor 413 continues to rotate in reverse, driving the first set of jet pipes 405 to rotate outwards and the second set of jet pipes 405 to rotate inwards. Driven by the forward and reverse motor 413, the first and second sets of jet pipes 405 maintain an alternating converging and opening pattern, rotating to spray air. When the jet pipes 405 converge, the airflow is concentrated and discharged towards the central area of ​​the activated carbon adsorption bed 402, increasing the airflow intensity in the central area. When they open outwards, the airflow diffuses to a wider area. Through this alternating convergence and opening, the discharged air forms a more uniform and comprehensive airflow coverage on the activated carbon adsorption bed 402, avoiding the situation where airflow is concentrated in localized areas, resulting in excess airflow in some areas and insufficient airflow in others. This allows the activated carbon's adsorption effect to be more efficient, reducing the residue of harmful gases in the air and improving the adsorption and removal rate of harmful gases.

A mounting bracket 208 is bolted to the bottom of the lower separation housing 205. The bottom end of the mounting bracket 208 is fixedly installed on the top of the air conditioner body 1. A support plate 213 is fixedly installed on the outer surface of the return air pipe 201. The bottom of the support plate 213 is fixedly installed at the edge of the top of the air conditioner body 1.

[0044] In this embodiment, during use, the fresh air duct on the side of the air conditioner body 1 is connected to the external fresh air pretreatment system. The air conditioner body 1 mainly consists of a ventilation system, an air handling system, a temperature control system, a humidity control system, and a control system. After the fresh air pretreatment system pre-treats the outside air, it enters the interior of the air conditioner body 1 through the fresh air duct. At the same time, the air inside the grain storage compartment enters the interior of the air conditioner body 1 through the intelligent switching component 2. The ventilation system mixes the outside air and the inside air. After being processed by the air handling system, the temperature is regulated by the temperature control system, the humidity is regulated by the humidity control system, and finally the air is delivered to the interior of the grain storage compartment through the air outlet duct. With the two second electric valves 210 closed and the two first electric valves 209 open, the air inside the grain storage compartment enters the air conditioner body 1 through the return air duct 201. The first humidity sensor 211 detects the humidity in the air, and the gas sensor 212 detects harmful gases in the air. The detected humidity data and harmful gas content data are transmitted to the PLC controller 207 for identification and analysis. When the humidity data or harmful gas content is abnormal, the PLC controller 207 controls the two first electric valves 209 to close and the two second electric valves 210 to open. This allows the air from the return air duct 201 to enter the upper separation housing 203 through the first switching pipe 202. The water vapor separation component 3 separates the water vapor in the air, and then the gas treatment component 4 adsorbs the harmful gases in the air. The treated clean air enters the bottom of the return air duct 201 through the second switching pipe 206 and is finally delivered to the air conditioner body 1. When humidity or harmful gas levels are within normal ranges, the PLC controller 207 closes the two second electric valves 210 and simultaneously opens the two first electric valves 209, allowing air to directly enter the air conditioner body 1 through the straight-through duct of the return air duct 201. The intelligent switching component 2 can switch the return air delivery path. When the air in the storage compartment is normal, the air directly enters the air conditioner body 1, improving operating efficiency. When the air is abnormal, it separates moisture from the air and adsorbs harmful gases, improving air purity and preventing moisture from accumulating in the air conditioner body 1, which could affect air filtration and prevent bacterial growth due to humidity.

[0045] The overall effect and working principle of the mechanism are as follows: During the process of air entering the air conditioner body 1 through the return air duct 201 from the grain storage compartment, the first humidity sensor 211 detects the humidity in the air, and the gas sensor 212 detects the harmful gases in the air. The detected humidity data and harmful gas content data are transmitted to the PLC controller 207 for identification and analysis. When the humidity data or harmful gas content is abnormal, the PLC controller 207 controls the two first electric valves 209 to close and the two second electric valves 210 to open, so that the air in the return air duct 201 enters the water vapor separation component 3 through the first switching pipe 202 to separate the water vapor in the air. Then, the gas treatment component 4 adsorbs the harmful gases in the air. The clean gas after treatment enters the bottom of the return air duct 201 through the second switching pipe 206 and is finally delivered to the air conditioner body 1. When the humidity data or harmful gas content is within the normal range, the PLC controller 207 controls the two second electric valves 210 to close and simultaneously opens the two first electric valves 209, allowing air to directly enter the air conditioner body 1 through the straight pipe of the return air duct 201. The conical shroud 303 is located at the center inside the horn tube 302. As the air flows downward, it directly impacts the outer surface of the conical shroud 303. The impact force causes water vapor in the air to adhere to the outer surface of the conical shroud 303 and gather into small water droplets. At the same time, the top tip of the conical shroud 303 breaks the incoming air, forcing the impacted air to flow along the inclined surface of the conical shroud 303, causing more water vapor to gather together. The water droplets enter the liquid collection ring 305 through the first liquid permeable membrane 306 and enter the liquid storage shroud 312 through multiple drain pipes 315. The air after water vapor separation is discharged through the exhaust pipe 307 and flows along the spherical shroud 301, impacting the outer roll of the roll-shaped shroud 308, achieving secondary separation of air and water vapor. The air then continues to flow along the rolled path of the roll-up hood 308, flowing downwards through multiple air outlet pipes 309. Meanwhile, water droplets on the outside of the roll-up hood 308 flow to the bottom area under gravity, passing through multiple liquid outlet holes 310 and the second permeable membrane 311 into the liquid storage hood 312, where the modified activated carbon-superabsorbent resin composite material absorbs water and adsorbs harmful gases. Next, air enters multiple flexible hoses 404 through the air outlet pipes 309 and connecting pipes 403, and is ejected downwards through multiple jet pipes 405, passing through the activated carbon adsorption bed 402 to adsorb harmful gases from the air. Start the forward and reverse motor 413, drive the rotating rod 412 to drive the long gear 411 to rotate, which in turn drives the two gear racks 410 to move in opposite directions, pushing the first moving plate 408 to move upward and the second moving plate 409 to move downward. The upward movement of the first rack 420 drives the corresponding flat gear 419 to rotate. The flip ring 417 drives a set of jet pipes 405 to rotate in a converging manner towards the center. At the same time, the second rack 421 moves downward, driving the flat gear 419 to rotate in the opposite direction. The flip ring 417 drives the two sets of jet pipes 405 to rotate outward in a dispersing manner.Then, the output of the forward and reverse motor 413 rotates in the opposite direction, driving the first set of jet pipes 405 and the second set of jet pipes 405 to rotate and reset. Then, the output of the forward and reverse motor 413 continues to rotate in the reverse direction. At this time, the first set of jet pipes 405 is driven to rotate outward and the second set of jet pipes 405 is driven to rotate inward. Under the drive of the forward and reverse motor 413, the first set of jet pipes 405 and the second set of jet pipes 405 maintain an alternating closing and opening mode to rotate and spray.

[0046] Among them, the air conditioner body 1, the first electric valve 209, the second electric valve 210, the first humidity sensor 211, the gas sensor 212, the second humidity sensor 214, the forward and reverse motor 413 and the PLC controller 207 are all existing technologies, and their components and operating principles are all publicly available technologies, which will not be explained in detail here.

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.
