Description

Technical Field

[0001] This application relates to the field of mechanical geotechnical testing technology, and in particular to a desalination device for calcareous sand. Background Technology

[0002] Calcareous sand is a special type of sandy soil, mainly formed from the bones and shells of marine organisms through long-term physical and chemical processes. Its main component is calcium carbonate. It is characterized by irregular particle shape, high porosity, and strong permeability, and is widely distributed in coral reefs, beaches, and other areas of tropical and subtropical marine environments. Untreated calcareous sand contains a large amount of salt, such as chlorides. These salts can cause electrochemical corrosion of steel reinforcement and other metallic materials in building structures, reducing the durability of building materials and thus affecting the safety and service life of buildings.

[0003] At this point, it is necessary to desalinate the calcareous sand. Existing desalination devices mix pure water and calcareous sand for desalination, but they cannot mix the pure water and calcareous sand more thoroughly, resulting in poor desalination effect on the calcareous sand.

[0046] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0047] Please see Figures 1 to 4 This application discloses a desalination device for calcareous sand, including a mixing tank 2 containing calcareous sand, and further comprising:

[0048] Infusion assembly for delivering demineralized water into mixing tank 2;

[0049] A stirring assembly is located inside mixing tank 2;

[0050] A drive assembly, connected to mixing tank 2, is used to enable mixing tank 2 to rotate in a vertical plane;

[0051] The transmission component is connected to the stirring component to enable the stirring component to stir the calcium sand and demineralized water while the mixing tank 2 is rotating;

[0052] The filter assembly, located below mixing tank 2, is used to separate the demineralized water and the desalinated calcium sand.

[0053] The desalinated water has fewer impurities and higher purity, which is beneficial for desalinating calcareous sand. The opening of mixing tank 2 can be threaded onto a sealing cap; alternatively, an injection pipe with a valve can be connected to the opening. The infusion assembly injects desalinated water into mixing tank 2 containing calcareous sand, mixing the desalinated water and calcareous sand. Then, the opening of mixing tank 2 is closed, and the drive assembly is activated, causing mixing tank 2 to rotate vertically. The transmission assembly allows the internal stirring assembly to rotate simultaneously with the vertical rotation of mixing tank 2, mixing the calcareous sand and desalinated water. The desalinated calcareous sand is then obtained through the filtration assembly. This process ensures more thorough mixing and contact between the calcareous sand and desalinated water, improving the desalination effect.

[0054] In a preferred embodiment, this application may be further configured such that the infusion assembly includes:

[0055] Water tank 9 contains demineralized water.

[0056] Water pump 8 is fixedly connected to water tank 9;

[0057] The water pump pipe is connected to the water pump 8 at one end and extends into the water tank 9 at the other end.

[0058] Water pipe 5 is connected at one end to water pump 8, and the other end can be located above mixing tank 2 to deliver demineralized water into mixing tank 2.

[0059] Start water pump 8 to transfer demineralized water from water tank 9 into mixing tank 2 through pump pipe and water delivery pipe 5, so that the demineralized water mixes with the calcium sand in mixing tank 2. During this process, the operator can hold water delivery pipe 5 so that the other end of water delivery pipe 5 is above the opening of mixing tank 2.

[0060] In a preferred embodiment, the infusion assembly may be further configured such that it includes a support frame 3 and a funnel 4. The funnel 4 is fixedly connected to the support frame 3 and located directly above the mixing tank 2. The funnel 4 is connected to a water delivery pipe 5. The other end of the funnel 4 and the water delivery pipe 5 are detachably connected, allowing the water delivery pipe 5 to extend into the funnel 4. This allows demineralized water to enter the mixing tank 2 through the funnel 4 without the need for manual assistance with the water delivery pipe 5, and avoids affecting the rotation of the mixing tank 2.

[0061] In a preferred embodiment, this application may be further configured such that the stirring assembly includes:

[0062] The stirring rod 14 is rotatably mounted inside the mixing tank 2, and the stirring rod 14 is connected to the transmission assembly.

[0063] Multiple stirring blades 15 are configured, and multiple stirring blades 15 are disposed on the outer peripheral wall of stirring rod 14.

[0064] When the mixing tank 2 rotates under the action of the drive component, the transmission component will cause the stirring rod 14 to rotate, thereby causing multiple stirring blades 15 to stir the calcium sand and demineralized water.

[0065] In a preferred embodiment, this application may be further configured such that the transmission assembly includes:

[0066] The mounting ring 6 is fixedly connected to the support frame 3. The mounting ring 6 has multiple toothed blocks on its surface near the mixing tank 2. The multiple toothed blocks are arranged in a ring-shaped interval.

[0067] Gear 7 is fixedly connected to stirring rod 14, and gear 7 meshes with multiple tooth blocks.

[0068] When the mixing tank 2 rotates, the gear 7 on the stirring rod 14 will rotate circumferentially along the mounting ring 6 during the meshing process with the tooth block, thereby enabling the stirring rod 14 and the stirring blade 15 to rotate at the same time as the mixing tank 2 rotates.

[0069] In a preferred embodiment, this application may be further configured such that the driving component includes:

[0070] Support 10;

[0071] The drive motor 1 is fixedly connected to the support 10;

[0072] The support rod 13 is fixedly connected at one end to the output shaft of the drive motor 1 and at the other end to the mixing tank 2.

[0073] Starting the drive motor 1 will cause the support rod 13 to rotate, which in turn causes the mixing tank 2 to rotate in the vertical plane. It is understood that a reducer can also be provided on the support 10. The output shaft of the drive motor 1 is connected to the reducer, which is in turn connected to the support rod 13. The drive motor 1 transmits power to the reducer, which increases the torque of the drive motor 1. This reduces the torque of the reducer, causing the support rod 13 to rotate, which in turn causes the mixing tank 2 to rotate, thus agitating the calcium sand and demineralized water inside the mixing tank 2.

[0074] In a preferred embodiment, this application may be further configured such that the filtering component includes:

[0075] Mounting box 11, with top fixed connection to support frame 3, water tank 9 and support 10;

[0076] The filter screen 20 is embedded in the top of the mounting box 11 and is located directly below the mixing tank 2.

[0077] The mounting box 11 provides space for the support frame 3, water tank 9, and support 10, making the structure more compact and saving space. After the calcium sand and demineralized water have been mixed for a period of time, the drive motor 1 is started so that the opening of the mixing tank 2 faces downward. The opening of the mixing tank 2 is opened so that the calcium sand and demineralized water fall together onto the filter screen 20 below. The demineralized water will enter the mounting box 11 through the filter screen 20, thereby achieving the separation of calcium sand and demineralized water and obtaining fully desalinated calcium sand.

[0078] In a preferred embodiment, this application may be further configured such that the filtering component also includes:

[0079] Mounting housing 18 is fixedly connected to the inner wall of mounting box 11;

[0080] The filter cartridge 17 is disposed inside the mounting housing 18, and the filter cartridge 17 is provided with multiple filter holes;

[0081] The delivery pipe 19 is located below the filter screen 20, and part of the delivery pipe 19 passes through the mounting housing 18 and extends into the filter cylinder 17.

[0082] The demineralized water separated from the calcium sand will fall into the conveying pipe 19 and enter the filter cylinder 17. The filter cylinder 17 is designed to filter out large particulate impurities in the demineralized water so that the demineralized water can be recycled.

[0083] In a preferred embodiment, the present application may be further configured as follows: a filter cartridge 17 is fixedly connected to a rotating shaft 16, the rotating shaft 16 is rotatably inserted through the mounting shell 18, the portion of the rotating shaft 16 located outside the mounting shell 18 is connected to a transmission structure 12, the top of the mounting box 11 is provided with a through hole, the transmission structure 12 passes through the through hole and is connected to the support rod 13, and a cleaning brush 21 that abuts against the filter cartridge 17 is provided inside the mounting shell 18.

[0084] When drive motor 1 is started, it causes support rod 13 to rotate, which in turn causes rotating shaft 16 to rotate via transmission structure 12. That is, by starting drive motor 1, not only can mixing tank 2 rotate, but also filter cartridge 17 can rotate. As filter cartridge 17 rotates, it remains in contact with cleaning brush 21, thus removing impurities from filter cartridge 17 and preventing clogging. Transmission structure 12 includes a synchronous belt and two synchronous pulleys. The two synchronous pulleys are connected to support rod 13 and rotating shaft 16 respectively, and the two ends of the synchronous belt are connected to the two synchronous pulleys respectively.

[0085] Working Principle: During use, the calcium sand to be treated is placed into the mixing tank 2. Then, the water pump 8 is started, drawing demineralized water from the water tank 9 into the water supply pipe 5. This water is then discharged through the funnel 4 into the mixing tank 2 to mix with the calcium sand. The demineralized water removes salt from the calcium sand. Afterward, the opening of the mixing tank 2 is closed, and the drive motor 1 is started. The output shaft of the drive motor 1 rotates, causing the support rod 13 to rotate. The support rod 13 drives the mixing tank 2 to rotate, agitating the calcium sand and demineralized water within the mixing tank 2, thus increasing the desalination effect of the brine. The rotation of the mixing tank 2 also drives the gear 7 to rotate on the surface of the mounting ring 6. The gear 7, through the toothed blocks on the mounting ring 6, drives the gear 7 to rotate. The gear 7, in conjunction with the stirring rod 14, causes the stirring blades 15 to rotate, further agitating the calcium sand and demineralized water while simultaneously improving the desalination effect on the calcium sand. After mixing and dilution are completed, the drive motor 1 can be controlled to rotate the mixing tank 2 downwards. Then, the opening of the mixing tank 2 can be opened again to discharge the calcium sand and demineralized water downwards. The water is initially filtered through the filter screen 20, and the filtered demineralized water is then filtered through the filter cylinder 17 to remove impurities. The demineralized water can then be further recycled.
