Description

Technical Field

[0001] This utility model relates to the field of soil remediation technology, and in particular to a soil dilution device for soil remediation. Background Technology

[0002] Soil pollution is receiving increasing attention. When testing soil remediation samples, the concentration of the substances to be tested is often very high, which may cause the instrument's detection limit to be much higher than the actual concentration of the substance, thus making accurate measurement impossible. Diluting soil samples can lower the concentration of the substances to be tested, bringing it down to the instrument's detection limit and improving the sensitivity and accuracy of the test. Therefore, appropriate dilution of soil samples is usually necessary before conducting soil remediation testing and analysis.

[0003] Chinese utility model patent CN218297772U discloses a soil dilution and dissolution device. Soil and solvent are poured into a beaker, which is then placed in a beaker retaining bracket. A fixing pin is pulled out, and the motor mounting plate is grasped. The telescopic rod is moved up or down as needed, allowing the stirrer to extend into the beaker. After adjustment, the fixing pin is inserted to secure the telescopic rod. The stirring motor is started, and a set of L-shaped and a set of arc-shaped stirring blades thoroughly mix the soil and solvent in the beaker. After mixing, the fixing pin is pulled out, the telescopic rod rises, and the beaker is removed. Different sized beaker retaining rings can be used to adapt to different beaker sizes. The L-shaped stirring blades agitate the mixture quickly, while the arc-shaped stirring blades cut the mixture horizontally, ensuring a more uniform mixing of soil and solvent.

[0004] Although the device uses a combination of L-shaped and arc-shaped stirring blades to make the soil and solvent mix more evenly, in actual use, the soil viscosity increases after it comes into contact with water, resulting in poor dispersibility in the solution and easy formation of agglomerates. Using only a single stirring blade for the dispersion and mixing operation in the dilution process can promote the mixing of soil and solution to a certain extent, but the stirring efficiency is limited and it is difficult to disperse agglomerates well, resulting in uneven mixing and low dilution efficiency.

[0012] In a preferred embodiment of this utility model, the feed cone is coaxially arranged with the dilution tank, and its inner diameter is the same as that of the dilution tank; the inner diameter of the filter holes on the filter plate is larger than the inner diameter of the filter holes on the filter screen.

[0013] In a preferred embodiment of the present invention, the power assembly includes: a turntable disposed on one side of the filter plate, a connecting rod disposed between the filter plate and the turntable, and a second motor installed on the top of the inner side of the support tank; the output end of the second motor is fixed to the bottom of the turntable via a rotating shaft.

[0018] This utility model solves the defects existing in the background technology, and has the following beneficial effects:

[0019] (1) This utility model provides a soil dilution device for soil remediation. By setting a dispersion component and an ultrasonic component at the bottom of the dilution tank, after the solvent and the soil to be diluted are put into the inside of the dilution tank, the soil can be repeatedly squeezed through the dispersion hole by the cooperation of the first motor, rotating rod, dispersion blade and dispersion hole, thereby improving the dispersion effect.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0027] like Figure 1-3 As shown, a soil dilution device for soil remediation includes: a support tank 1, a dilution tank 2 disposed inside the support tank 1, and a dispersion component and an ultrasonic component disposed at the bottom of the dilution tank 2; the dispersion component includes: a first motor 3 installed at the bottom of the dilution tank 2, a rotating rod 31 fixed to the output end of the first motor 3, and a plurality of dispersion blades 32 installed on the side of the rotating rod 31; the plurality of dispersion blades 32 are inclined in the same direction of rotation, and a plurality of dispersion holes 33 are opened on the inclined surface of the dispersion blades 32; the ultrasonic component includes: an ultrasonic generator 4 disposed at the bottom of the inner side of the support tank 1, and a plurality of piezoelectric transducers 41 disposed at the bottom of the dilution tank 2; the ultrasonic generator 4 is electrically connected to the plurality of piezoelectric transducers 41.

[0028] It should be noted that the top of the dilution tank 2 extends to the top of the support tank 1, and the rotating rod 31 is located inside the dilution tank 2, with its side near the bottom rotatably connected to the inner side of the dilution tank 2. After the solvent and the soil to be diluted are put into the dilution tank 2, the rotating rod 31 and the dispersing blade 32 are driven to rotate by the first motor 3. The dispersing blade 32 and the dispersing holes 33 opened on the inclined surface of the dispersing blade 32 allow the soil to be repeatedly squeezed through the dispersing holes 33, thereby improving the dispersion effect. While stirring and dispersing, the ultrasonic generator 4 transmits sound waves to the piezoelectric transducer 41. After receiving the sound waves, the piezoelectric transducer 41 converts electrical energy into mechanical energy using the piezoelectric effect, which can achieve ultrasonic vibration of the dilution tank 2. Combined with the cavitation effect of ultrasonic vibration, tiny bubbles can be generated in the liquid and rapidly collapse to release energy, which can effectively break the agglomeration between soil particles and promote the dispersion of soil particles in the solution, thereby significantly improving the soil dilution effect and efficiency.

[0029] like Figure 3As shown, in some embodiments, a plurality of dispersing blades 32 are evenly distributed in a circular array in the planar direction, and a plurality of dispersing blades 32 are evenly distributed in a linear array in the vertical direction; by the even distribution of the dispersing blades 32 in the planar and vertical directions, it can be ensured that the soil can be evenly and fully dispersed in the dilution tank 2, thereby improving the dilution efficiency.

[0030] In some embodiments, a feed cone 5 is fixed to the top of the support tank 1, and a filter mechanism is provided on the feed cone 5. The filter mechanism includes: a filter plate 51 slidably connected to the inner side of the feed cone 5, a filter screen 52 fixed to the inner side of the feed cone 5, and a power assembly provided on the top of the support tank 1 for driving the filter plate 51 to reciprocate and translate; the two sides of the filter plate 51 extend to the outside of the feed cone 5, and the bottom contacts the top of the filter screen 52.

[0031] It should be noted that the feed cone 5 is coaxially arranged with the dilution tank 2, and its inner diameter is the same as that of the dilution tank 2; the inner diameter of the filter holes on the filter plate 51 is larger than that on the filter screen 52; after the soil to be diluted is put into the feed cone 5, the soil can be filtered through the cooperation of the filter plate 51 and the filter screen 52, and through the cooperation of the power component, the filter plate 51 is driven to reciprocate inside the feed cone 5. By utilizing the size difference of the inner diameter of the filter holes between the filter plate 51 and the filter screen 52, a certain crushing effect can be achieved for larger particles. It can not only crush a certain amount of soil particles, but also remove excessively large particle impurities and agglomerates, thereby further improving the dilution effect after dispersion and mixing.

[0032] like Figure 1 and Figure 3 As shown, in some embodiments, the power assembly includes: a turntable 6 disposed on one side of the filter plate 51, a connecting rod 61 disposed between the filter plate 51 and the turntable 6, and a second motor 62 installed on the top of the inner side of the support tank 1; the output end of the second motor 62 is fixed to the bottom of the turntable 6 via a rotating shaft.

[0033] It should be noted that one end of the connecting rod 61 is hinged to the top of the filter plate 51, and the other end is eccentrically hinged to the top of the turntable 6. Through the rotation output of the second motor 62, the rotating shaft drives the turntable 6 to rotate. Since the connecting rod 61 is eccentrically hinged to the turntable 6, the rotation of the turntable 6 will be converted into the reciprocating translational motion of the filter plate 51, thereby realizing continuous filtration and a certain degree of crushing of the soil.

[0034] like Figure 2 As shown, in some embodiments, a support ring 7 is fixed to the side of the dilution tank 2, and the side of the support ring 7 is fixed to the inside of the support tank 1. By fixing the support ring 7 to the side of the dilution tank 2 and to the inside of the support tank 1, the dilution tank 2 can be provided with additional support and stability, ensuring that it will not shake or deform during operation.

[0035] In some embodiments, an inlet pipe 8 is fixed to the side of the dilution tank 2 near the top, and the top end of the inlet pipe 8 extends through to the top of the support tank 1; the inlet pipe 8 facilitates the addition of the solvent required for dilution into the dilution tank 2 from the outside of the support tank 1.

[0036] In some embodiments, a discharge pipe 9 is fixed to the bottom of the dilution tank 2, and a solenoid valve is installed on the side of the discharge pipe 9. One end of the discharge pipe 9 extends through to the side of the support tank 1. The diluted soil can be discharged through the discharge pipe 9. The solenoid valve is used to control the opening and closing of the discharge pipe 9 to adjust the discharge speed and flow rate, so that the staff can control the output of the diluted soil according to actual needs.

[0037] In use, the soil to be diluted is fed into the feed cone 5. The soil is filtered by the filter plate 51 and filter screen 52 of the filter material mechanism. Driven by the power component, the filter plate 51 is rotated by the second motor 62 via the rotating shaft, which drives the turntable 6 to rotate. The turntable 6, through the eccentrically hinged connecting rod 61, causes the filter plate 51 to reciprocate inside the feed cone 5, achieving continuous filtration and a certain degree of crushing of the soil, removing excessively large particles and agglomerates. Subsequently, the solvent is added through the liquid inlet pipe 8 on the side of the dilution tank 2. Then, the first motor 3 is started, driving the rotating rod 31 and the dispersing blades 32 to rotate. The dispersing blades 32 are inclined in the same direction of rotation, and the dispersing holes 33 on their inclined surfaces cause the soil to repeatedly pass through, forming compression and improving the dispersion effect. Simultaneously, the ultrasonic generator 4 transmits sound waves to the piezoelectric transducer 41 at the bottom of the dilution tank 2. The piezoelectric transducer 41 uses the piezoelectric effect to convert electrical energy into mechanical energy, achieving ultrasonic vibration of the dilution tank 2. Combined with the cavitation effect of ultrasonic vibration, this breaks up the aggregation between soil particles and promotes the dispersion of soil particles in the solution. After dilution is completed, the output of diluted soil is controlled by the discharge pipe 9 at the bottom of the dilution tank 2 and the solenoid valve.
