[0011] Preferably, the water tank 5 is used to provide the water required by the water circulation system 7.

[0012] Preferably, the waste sand collection device 6 is used to collect the waste sand remaining after sorting from the waste sand outlet pipe 402.

[0013] Preferably, the water circulation system 7 includes a water pump 701 for the stirring device, a water inlet pipe 702 for the water pump 703 for the water pump 704 for the sand-water separation device, a water outlet pipe 705 for the sand and water collection device, and a water pump 706 for pumping the upper layer sand-water mixture.

[0015] Accordingly, a method for using a fully automatic sediment separator includes the following steps:

[0016] Step 1: Add an appropriate amount of sand sample to the sand adding device 1, add an appropriate amount of water to the water tank 5, set the stirring speed, stirring time, and settling time through the control panel 8, and start the instrument. The instrument will start running and display the temperature and estimated amount of sand required.

[0017] Step 2: Turn off the instrument and, in conjunction with equipment such as Malvern for measuring the particle size and gradation of suspended sand, measure the particle size or gradation of the sand in the sand collection device 3; start the instrument and continuously adjust the stirring speed to obtain a suitable stirring speed.

[0018] Step 3: After obtaining a suitable stirring speed, set the amount of water added, amount of sand added, stirring time, stirring speed, settling time, and amount of mud and sand taken through the control panel 8, and then officially enter the sorting process;

[0019] Step 4: After obtaining the required amount of sand, the instrument stops running, and the control panel 8 displays the actual amount of sand used and the extraction rate.

[0020] Step 5: Turn off the instrument. The sand with the required particle size or gradation will be collected from the sand collection device 3.

[0021] The beneficial effects of this invention are as follows: The fully automatic sediment separator of this invention can separate extremely fine sediment particles of specific size or gradation from a large amount of sediment. Because the stirring speed can be set, the separation accuracy is high, making it particularly suitable for laboratory and field separation. It requires no manual operation, is highly efficient, simple and convenient to operate, and requires no manual cleaning. It can automatically separate the required mass of sand and place it in a specific container, while displaying the extraction rate on the operation panel, making sand collection convenient. It has a complete water circulation system, realizing the recycling of water during the separation process. Only a certain amount of water needs to be placed in the water tank, resulting in significant water conservation during large-scale separation. At the same time, it reduces wastewater generated during separation, reducing environmental impact. The main tank is transparent, allowing observation of the sediment movement inside the tank to obtain patterns for further research. It is highly flexible, with bottom support rollers for easy movement. The sand adding device, top panel, and top support are detachable to meet different needs. Attached Figure Description

[0034] like Figure 1As shown, a fully automatic sediment separator includes: a sand adding device 1, a mixing device 2, a water filtering and sand collecting device 3, a sand-water separation device 4, a water tank 5, a waste sand collection device 6, a water circulation system 7, a control panel 8, and a support system 9. The waste sand collection device 6 is placed on the ground below the bottom panel 903 in the support system 9. The water tank 5 and the sand-water separation device 4 are placed on the bottom panel 903. The mixing device 2 and the water filtering and sand collecting device 3 are placed on the middle panel 905 in the support system 9. The sand adding device 1 is placed on the upper panel 907 in the support system 9. The support system 9 includes a bottom support 901, bottom support rollers 902, a bottom panel 903, and a middle support 904. The instrument comprises a middle layer panel 905, an upper layer support 906, an upper layer panel 907, a top layer support 908, and a top layer panel 909. The bottom layer support 901 is welded to the bottom layer support roller 902 to allow for free movement of the instrument. The bottom layer panel 903 is welded to the top of the bottom layer support 901. The lower end of the middle layer support 904 is welded to the bottom layer panel 903, and the upper end is welded to the middle layer panel 905. The lower end of the upper layer support 906 is welded to the middle layer panel 905, and the upper end is welded to the upper layer panel 907. The lower end of the top layer support 908 is connected to the upper layer panel 907 with screws, and the upper end is welded to the top layer panel 909. The top layer support 908 and the top layer panel 909 are detachable to meet different needs.

[0035] like Figure 2 , Figure 3 and Figure 10 As shown, the top panel 909 is connected to the sand-adding stirring rod 105 via a spiral interface. The lower part of the sand-adding main tank 101 is a sand-adding funnel 104, which is also connected via a spiral interface. A sand control valve 107 is located at the lower end of the sand-adding funnel 104. A fixing plate 102 is welded to the lower end of the sand-adding main tank 101, and a plate 103 that can rotate with the stirring rod 105 is welded to the lower end. The sand-adding pressure sensor 106 has a diameter of 30mm and a thickness not exceeding 1mm. The sand-adding pressure sensor 106 is placed inside the waterproof container 108 and attached to the bottom of the inner wall of the sand-adding funnel.

[0036] The fixed plate 102 and the rotatable plate 103 have circular holes distributed on them. When the rotatable plate 103 rotates with the rod, the circular holes on the two plates overlap, allowing sand particles to leak down. The sand pressure sensor 106 at the bottom of the inner wall of the sand adding funnel controls the rotation of the sand adding stirring rod 105 by the pressure change caused by the leaking sand particles. This controls the overlap between the circular holes on the rotatable plate 103 and the circular holes on the fixed plate 102, thereby controlling the start and stop of sand particle leakage and achieving the goal of quantitatively adding raw material mud and sand. The sand adding device 1 is detachable.

[0037] Before starting the instrument, add an appropriate amount of sand sample to the device. Start the instrument, and the sand mixing rod 105 will start running to stir the sand sample. At the same time, the sand mixing rod 105 drives the plate 103, which can rotate with the rod, to rotate. The sand sample is discharged by the overlap of the plate 103, which can rotate with the rod, and the sand control valve 107 and the sand mixing rod 105 are controlled by the sand pressure sensor 106 to open and close, as well as to run and stop, so as to achieve quantitative addition of sand sample.

[0038] like Figure 4 , Figure 5 and Figure 11 As shown, the sand-water mixing rod 205 is fixed to the upper panel 907 via a spiral interface. The mixing blades 206 are four quarter-circles welded to the bottom of the sand-water mixing rod 205. The mixing main tank 201 is connected to the funnel-shaped waste sand-water discharge port 202 via a spiral interface and is embedded in the tabletop. The upper sand-water mixture pumping pipe 203 is connected to the top of the mixing main tank 201. The electric timed drain valve 204 is spirally fixed to the upper part of the straight section of the funnel-shaped waste sand-water discharge port 202. The upper part of the inner wall of the mixing main tank 201 is bonded with a waterproof container 207 of the same material as the mixing main tank 201. The water depth sensor 208 is placed inside the container. The length of the water depth sensor detection air pipe 209 can be set as needed.

[0039] The stirring blades 206 are four quarter circles, which can be combined into a disc after the sand-water mixture has settled, dividing the stirring device 2 into two parts to separate the required part from the rest. The funnel-shaped waste sand-water discharge port 202 is set in the shape of a funnel with a certain angle to facilitate the discharge of waste sand and water. The upper sand-water mixture pumping pipe 203 draws out the upper sand-water mixture. The electric timed drain valve 204 controls the discharge of the lower waste sand and wastewater. The water depth sensor 208 controls the opening and closing of the water pump 701 of the stirring device by capturing the change in the liquid level in the main stirring tank 201, so that the liquid level in the main stirring tank 201 remains constant during the operation of the non-sand-water stirring rod 205.

[0040] like Figure 6 and Figure 8 As shown, the water filtration and sand collection device 3 consists of a side wall 301 and a funnel-shaped outlet 302. The funnel-shaped outlet 302 is welded to the lower end of the side wall 301. The bottom of the side wall 301 is provided with filter paper and a circular baffle 304 with small holes on its edge. The circular baffle 304 with small holes is welded to the side wall 301 and is located below the filter paper to support it. A closed cylindrical container 303 is welded to the bottom of the circular baffle 304 with small holes to hold a sediment pressure sensor 305, which is attached below the circular baffle 304 with small holes.

[0041] The funnel-shaped outlet 302 is designed in a funnel shape to facilitate the discharge of wastewater. The filter paper is a water-permeable but sand-impermeable material used to separate sand and water. The circular baffle 304 with a small hole is used to support the filter paper and discharge wastewater. The sediment pressure sensor 305 controls the operation of the water pump 701 in the stirring device of the water circulation system 7 and the sand control valve 107 in the sand adding device 1 by controlling the pressure change caused by sediment accumulation, thereby increasing or decreasing the amount of sand added. When the required sand mass is set, it plays a role in controlling whether the entire device operates.

[0042] The water filtration and sand collection device 3 can increase the filtration speed by accelerating the filtration device; the stirring blades 206 gradually reduce the speed, and after the speed of each stage stabilizes, the water filtration and sand collection device 3 takes samples, and the particle size and gradation of the suspended sand are measured with Malvern and other equipment for measuring the particle size and gradation of the suspended sand, and the speed of the stirring blades 206 is adjusted until the particle size and gradation of the suspended sand meet the requirements.

[0043] like Figure 7 As shown, the sand-water separation device 4 consists of a main rotating unit 401, a sand-water separation device outlet 406, a sand-water separation device inlet pipe 405, and a waste sand outlet pipe 402. The sand-water separation device outlet 406 is located above the main rotating unit 401, the sand-water separation device inlet pipe 405 is located on the side of the main rotating unit 401, and the waste sand outlet pipe 402 is located below the main rotating unit 401; all are connected to the main rotating unit 401 by welding. The sand-water separation device inlet pipe 405 is connected to the funnel-shaped waste sand-water discharge port 202 via a spiral interface of the sand-water separation device pump 404.

[0044] The sand-water mixture is tangentially fed into the main rotating unit 401 under a certain pressure from the funnel-shaped waste sand-water discharge port 202 along the sand-water inlet pipe 405 of the sand-water separation device. Particles in the outer swirling flow are subjected to centrifugal force; particles with a density greater than the surrounding liquid experience increasingly stronger centrifugal forces. Sand particles in the outer swirling flow are thrown against the outer barrel wall 403 by centrifugal force and then move downwards, flowing out through the waste sand outlet pipe 402. Water remains in the inner circumference and enters the conical section. As the inner diameter of the hydrocyclone gradually decreases, the liquid rotation speed increases. The area near the center becomes a low-pressure zone or even a vacuum zone, thus creating an upward rotational motion, which is discharged at the top sand-water separation device outlet 406 along the sand-water separation device outlet pipe 704. The water pump 404 of the sand-water separation device is used to control the speed of the sand-water mixture to achieve the separation effect.

[0045] Water tank 5 is used to supply water required by water circulation system 7. Waste sand collection device 6 is used to collect waste sand remaining after sorting from waste sand outlet pipe 402.

[0046] like Figure 9As shown, the water circulation system 7 consists of a water pump and several water pipes. Water in the water tank 5 enters the water pump 701 of the stirring device through the water inlet pipe 702, and then enters the stirring device 2 through the water outlet pipe 703. Water in the upper layer of the stirring device 2 enters the upper layer sand-water mixture pump 706, successively through the upper layer sand-water mixture pump pipe 203, the upper layer sand-water mixture pump 706, the sand and water filtration device 3, and the sand and water filtration device outlet pipe 705, finally returning to the water tank 5. Water in the lower part of the stirring device 2 enters the sand and water separation device 4 through the funnel-shaped waste sand and water discharge port 202, the sand and water separation device pump 404, and the sand and water separation device inlet pipe 405, then enters the sand and water separation device outlet pipe 704 through the sand and water separation device outlet 406, finally returning to the water tank 5. This water circulation method achieves the purpose of water conservation.

[0047] The control panel 8 consists of a water addition switch, a sand addition switch, water addition amount, sand addition amount, stirring time, stirring speed, settling time, amount of mud and sand taken, temperature display, estimated amount of sand required, actual amount of sand used, and extraction rate.

[0048] The water-sand mixing ratio is obtained by controlling the amount of water and sand added. The desired particle size or gradation of the sediment is achieved by setting the stirring time, stirring speed, and settling time. The mass of sand particles released each time is controlled by a sand pressure sensor at the bottom of the sand funnel's inner wall, thus determining the actual amount of sand used. The amount of sediment extracted is controlled by a sensor, which adjusts the sand addition. The extraction rate is the ratio of the extracted sediment amount to the actual amount of sand used.

[0049] In this invention, the sand-adding device includes a stirring device and a quantitative adding device for automatic and quantitative addition of sediment. The stirring device includes a straight cylinder and a funnel for sediment sorting, separation, and discharge of waste sand and water. The sand-water collection device includes a filtration device and a weighing device for separating sand and water from the extracted portion and quantitatively obtaining the required amount of sand. The sand-water separation device includes a main rotating body and three pipe systems for separating waste sand and water. A water tank is used to hold the water used. A waste sand collection device is used to hold the separated waste sand. A water circulation system is used to achieve the water circulation purpose of this instrument and improve water utilization efficiency. A control panel is used to control the start, stop, and parameter settings of the instrument. A support is used to fix the various parts of the device. The device of this invention has the advantages of simple operation, flexible assembly, no need for manual operation, high accuracy, and environmental protection and energy saving. When used with equipment such as Malvern for measuring the particle size and gradation of suspended sediment, it can separate extremely fine particles of sediment with specific particle size or gradation from a large amount of sediment.
