Description

Technical Field

[0001] This utility model relates to the field of soil testing technology, specifically a soil suspension density testing device. Background Technology

[0002] In the field of soil physicochemical property testing, the hydrometer method is an important means of determining the density of soil suspensions to obtain key parameters such as soil particle composition and porosity. However, in actual testing, foam easily forms on the surface of the suspension, seriously interfering with the accurate reading of the hydrometer scale. Traditional physical defoaming methods, such as the settling method, require a lot of time to wait for the foam to dissipate naturally, which seriously affects the testing efficiency; ultrasonic defoaming can quickly defoam, but it requires specialized equipment, is complex to operate, and is costly; the use of chemical defoamers may introduce impurities, change the chemical properties of the soil suspension, and lead to distorted test results. Summary of the Invention The technical problem to be solved by this utility model is to provide a soil suspension density detection device that can eliminate foam interference and assist in accurate readings, thus meeting the dual requirements of accuracy and efficiency in actual testing work.

[0003] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a soil suspension density detection device, including a measuring cylinder and a density meter, wherein an annular plate is provided at the top opening of the measuring cylinder, an annular air bladder is provided inside the annular plate, and multiple downward-facing air jet pipes are provided on the air bladder.

[0004] In a preferred embodiment, the annular plate includes an annular body, and an annular extension plate is provided along the outer circumference of the annular plate; The outer diameter of the annular body is the same as the inner diameter of the measuring cylinder, the radial width of the annular extension plate is greater than the wall width of the measuring cylinder, and the annular extension plate rests on the top opening of the measuring cylinder.

[0005] In a preferred embodiment, the lower edge of the inner circular surface of the annular plate is provided with an airbag groove. The airbag groove is an annular component with an "L" shaped cross-section. The airbag groove and the annular plate cooperate to form a circumferential groove, and the airbag is disposed in the groove.

[0006] In a preferred embodiment, multiple through holes are evenly distributed around the bottom surface of the groove, and multiple air jet pipes on the airbag are arranged one-to-one through the through holes.

[0007] In a preferred embodiment, an air intake pipe is connected to the airbag, and the air intake pipe is connected to an air pump.

[0008] In a preferred embodiment, the outer wall of the measuring cylinder is provided with a sleeve, and an opening is provided on the side wall of the sleeve, in which a magnifying lens is installed.

[0009] In a preferred embodiment, a vertical groove is provided on the inner wall of the sleeve, and an LED light is installed in the vertical groove.

[0010] In a preferred embodiment, a transparent baffle is provided on the inner side of the vertical groove.

[0011] In a preferred embodiment, the LED light and the magnifying lens are positioned at the same axial height on the sleeve, and are arranged symmetrically between them.

[0012] The soil suspension density detection device provided by this utility model, by adopting the above-described structure, has the following beneficial effects: (1) By setting an annular plate and an internal airbag structure at the top of the measuring cylinder, the airflow is directed to the liquid surface by the jet pipe, which can quickly break the foam. Compared with the traditional static defoaming method, the detection time is significantly shortened. The annular plate adopts the design of the extension plate overlapping with the top surface of the measuring cylinder, which ensures that the device is stable and easy to disassemble and clean, and avoids the residual suspension contaminating the airbag. The "L" shaped cross section design of the airbag groove provides stable support and facilitates the orderly arrangement of the jet pipe, making the defoaming airflow distribution more uniform. (2) The sleeve and magnifying lens set on the outer wall of the measuring cylinder, combined with the LED light and transparent baffle, provide side lighting in low light conditions, significantly improving the clarity of the scale. The symmetrical arrangement of the LED light and magnifying lens effectively reduces reflection interference and ensures a clear reading field. Attached Figure Description

[0018] like Figure 1-4In the present invention, a soil suspension density detection device includes a measuring cylinder 1 and a density meter 2. The measuring cylinder 1 has an annular plate 3 at the top opening, and an annular air bladder 4 is provided inside the annular plate 3. The air bladder 4 is provided with multiple downward-facing air jets 5.

[0019] In a preferred embodiment, the annular plate 3 includes an annular body, and an annular extension plate 9 is provided along the outer circumference of the annular plate; The outer diameter of the annular body is the same as the inner diameter of the measuring cylinder 1, the radial width of the annular extension plate 9 is greater than the wall width of the measuring cylinder 1, and the annular extension plate 9 rests on the top opening of the measuring cylinder 1.

[0020] In a preferred embodiment, the lower edge of the inner circular surface of the annular plate is provided with an airbag groove 10. The airbag groove 10 is an annular part with an "L" shaped cross section. The airbag groove 10 and the annular plate cooperate to form a circumferential groove, and the airbag 4 is disposed in the groove.

[0021] In a preferred embodiment, a plurality of through holes 11 are evenly distributed around the bottom surface of the groove, and a plurality of jet pipes 5 provided on the airbag 4 are arranged to pass through the through holes 11 in a corresponding manner.

[0022] In a preferred embodiment, an air inlet pipe 6 is connected to the airbag 4, and the air inlet pipe 6 is connected to an air pump.

[0023] In a preferred embodiment, the outer wall of the measuring cylinder 1 is provided with a sleeve 7, and an opening is provided on the side wall of the sleeve 7, in which a magnifying lens 8 is installed.

[0024] In a preferred embodiment, a vertical groove 12 is provided on the inner wall of the sleeve 7, and an LED light 14 is installed in the vertical groove 12.

[0025] In a preferred embodiment, a transparent baffle 13 is provided on the inner side of the vertical groove 12.

[0026] In a preferred embodiment, the LED light 14 and the magnifying lens 8 are positioned at the same axial height on the sleeve 7, and are arranged symmetrically between them.

[0027] The soil suspension density detection device disclosed in this utility model is used when performing soil suspension density detection operations: Place the hydrometer 2 inside the measuring cylinder 1, and then smoothly place the annular mounting plate 3 onto the opening on the top surface of the measuring cylinder 1 via the annular extension plate 9, ensuring that the annular body is tightly fitted to the inner wall of the measuring cylinder 1, so that the airbag 4 is securely installed in the airbag groove 10 on the lower edge of the inner circular surface of the annular plate. Connect the air inlet pipe 6 on the airbag 4 to the air pump to complete the installation of the defoaming component. Check the sleeve 7 on the outer wall of the measuring cylinder 1 to ensure that the magnifying lens 8, LED light 14 and transparent baffle 13 are installed properly.

[0028] The prepared soil suspension is carefully poured into graduated cylinder 1. When foam appears on the surface, the air pump is turned on. The air pump forces air into the air bladder 4 through the air inlet pipe 6. The air in the air bladder 4 is then sprayed downwards onto the surface of the suspension through multiple jet pipes 5 evenly distributed on the air bladder 4. Jetting continues for 10-30 seconds (adjusted according to the amount of foam) until the foam is mostly eliminated. During this process, the directional airflow from the jet pipes 5 impacts the surface of the suspension, disrupting the liquid film structure of the foam and causing it to rupture and dissipate. The overlapping design of the annular extension plate 9 of the annular plate 3 with the top surface of the graduated cylinder 1 ensures the stability of the device during the jetting process. The air bladder groove 10 limits the position of the air bladder 4, ensuring the fixed position of the jet pipes 5 and uniform airflow distribution, achieving a highly efficient defoaming effect.

[0029] After completing the above defoaming operation, turn off the air pump and wait for the hydrometer to stabilize and float. Then, turn on the LED light inside the sleeve 7, projecting the light evenly into the measuring cylinder 1. The inspector adjusts the vertical position of the sleeve 7 on the measuring cylinder 1 so that the liquid level is at the same horizontal height as the magnifying lens 8, and observes the hydrometer scale through the magnifying lens 8 on the side wall of the sleeve 7.

[0030] After reading the densitometer scale value, record the test data, including soil sample number, test time, and suspension density reading. After the test is completed, disassemble the annular plate 3, remove the airbag 4 for cleaning to prevent suspension residue from clogging the air jet pipe 5; rinse the measuring cylinder 1 and sleeve 7, clean them thoroughly, and store them properly for future use.
