Description

Technical Field

[0001] The utility model relates to the technical field of sea sand cleaning, in particular to a device for processing original sea sand samples for testing. Background Art

[0002] Currently, technologies such as desalination are available for treating sea sand resources, but they are still costly, especially for using sea sand as foundation for island construction. Microbially induced calcium carbonate precipitation (MICP), a novel soil stabilization method, has attracted attention for its cost-effectiveness, low-carbon, and environmentally friendly characteristics. Therefore, it is necessary to conduct different microbial tests on local raw sand samples to obtain a variety of data to develop more accurate methods for utilizing sea sand resources. To maintain the properties and composition ratio of the original sand samples, the processing of raw sand samples is limited. Existing technologies require large-scale equipment, making them unsuitable for processing small amounts of sea sand for testing. Furthermore, existing equipment directly discharges the cleaned sea sand without drying or sterilizing it. Contaminated bacteria can affect the results of subsequent MICP tests, making the results of cleaned sea sand inaccurate and unable to be reflected on the original sea sand. Utility Model Content

[0003] In response to the above-mentioned existing technology, the utility model provides a device for processing raw sea sand samples for testing, which can process a small amount of sea sand used for testing, ensure the original component ratio of the sea sand used for testing, and dry and sterilize it so that the processed sea sand samples can meet the requirements for testing.

[0018] The following is a further detailed description of the technical solution of the present invention in conjunction with the accompanying drawings and specific embodiments of the specification. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art to which the present invention belongs. The terms used herein in the specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. In the following description, reference is made to "some embodiments", which describes a subset of all possible embodiments, but it should be understood that "some embodiments" may be the same subset or different subsets of all possible embodiments, and may be combined with each other without conflict.

[0019] Example 1

[0020] Combined with reference to Figures 1 to 2 The utility model provides a device for processing raw sea sand samples for testing, comprising a cleaning bucket 1, a feeding pipe 7 and a water inlet pipe 8 being provided at the top of the cleaning bucket 1, a first filter screen 4 and a first electric valve 16 being provided at the bottom of the cleaning bucket 1, the first filter screen 4 being connected to a first sewage pipe 9, a first valve 15 being provided on the first sewage pipe 9, the first electric valve 16 being connected to a sand outlet pipe 12, a rotating shaft 18 being provided inside the cleaning bucket 1, a stirring rod 19 being connected to the rotating shaft 18, the lower end of the sand outlet pipe 12 being connected to a drying box 2, a heater 14 being provided inside the drying box 2, an exhaust pipe 13 being provided at the top of the drying box 2, a second electric valve 17 being provided at the bottom of the drying box 2, the lower end of the second electric valve 17 being connected to a discharge pipe 11, and the lower end of the discharge pipe 11 being connected to a cooling tank 3. During use, the feed pipe 7 transports the original sand sample into the cleaning bucket 1, and the water inlet pipe transports clean water into the cleaning bucket 1. The rotating shaft 18 drives the stirring rod 19 to rotate and stir, stirring and cleaning the original sand sample in the cleaning bucket 1. After cleaning, the first valve 15 is opened to discharge the sewage from the first sewage pipe 9. The first filter screen 4 prevents the sea sand from being discharged together with the sewage. After cleaning, the first valve 15 is closed and the first electric valve 16 is opened. The cleaned sea sand enters the drying box 2 through the sand outlet pipe 12. Under the action of the heater 14, the temperature of the sea sand is increased, so that the moisture in the sea sand is vaporized into water vapor faster and discharged from the exhaust pipe 13 for drying treatment. At the same time, a sterilization treatment is performed. The dried sea sand is transported to the cooling tank 3 through the discharge pipe 11. After cooling, the sea sand for testing can be obtained.

[0021] Preferably, the lower portion of the cleaning barrel 1 is funnel-shaped, and the first electric valve 16 and the first filter screen 4 are connected to the lowermost portion of the cleaning barrel 1. The funnel-shaped lower portion of the cleaning barrel 1 can discharge all sewage in the cleaning barrel 1. Due to gravity, after the first electric valve 16 is opened, all sea sand flows from the sand outlet pipe 12 below to the drying box 2, so that no part of the sample is retained in the cleaning barrel 1.

[0022] Preferably, a scraper 20 is provided at the bottom end of the rotating shaft 18. The scraper 20 is V-shaped, and both ends of the scraper 20 are parallel to the bottom of the cleaning bucket 1. The scraper 20 can more conveniently stir all the sample sea sand to ensure that all samples are stirred and cleaned. At the same time, the scraper 20 can also scrape off the sample sea sand adhering to the bottom of the cleaning bucket 1 to ensure that all the sample sea sand enters the drying box.

[0023] Preferably, the stirring rod 19 and the scraper 20 are both provided with bristles 21. The presence of the bristles 21 ensures that the sample sea sand is cleaned in all directions and that the debris in the sea sand holes can be cleaned.

[0024] Preferably, the heater 14 is a continuous S-shaped, and the drying box 2 is provided with multiple layers of heaters 14. The dense arrangement of the heaters 14 can make the wet sample sea sand dry and sterilize faster, saving processing time.

[0025] Preferably, the bottom of the drying box 2 is funnel-shaped, and the second electric valve 17 is connected to the lowest point of the funnel-shaped bottom of the drying box 2. The funnel-shaped design of the bottom of the drying box 2 facilitates the dried sample sea sand to enter the cooling tank 3 from the discharge pipe 11 due to the effect of gravity.

[0026] Preferably, a second filter screen 5 is provided at the bottom of the drying box 2, and the second filter screen 5 is connected to a drain pipe 10. If the moisture content of the wet sea sand sample entering the drying box 2 is too high, the moisture can be further drained through the drain pipe 10, so that the wet sea sand sample is dried faster. The second filter screen 5 ensures that the sample sea sand will not be discharged.

[0027] Example 2

[0028] See attached Figure 3 The difference between this embodiment and the first embodiment is that a third filter screen 6 is provided at different heights of the cleaning bucket 1. The third filter screen 6 is connected to a second sewage pipe 22, and a fourth valve 23 is provided on the second sewage pipe 22. Due to the characteristics of the sea sand itself, the sewage after cleaning passes through the sample sea sand and then through the first filter screen 4, and finally discharged through the first sewage pipe 9. The purification effect of the sample sea sand itself will make the sewage discharge incomplete, causing some impurities in the sewage to be re-adsorbed on the sea sand, and the sample sea sand cannot be completely cleaned. Therefore, the third filter screen 6 is provided at different heights of the cleaning bucket 1. Opening the fourth valve 23 allows sewage of different depths to pass through the third filter screens 6 at different heights and then be discharged from the second sewage pipe 22. This makes the sewage discharge faster and prevents the re-precipitation of impurities in the sewage and thus contamination of the cleaned sea sand.

[0029] The above are only specific embodiments of the present invention, but the scope of protection of the present invention is not limited to them. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this utility model should be included in the scope of protection of the present utility model. The scope of protection of the present utility model should be based on the scope of protection of the claims.
