Description

Technical Field

[0001] This invention belongs to the field of marine sediment technology, specifically a device and method for filtering and purifying marine sediment samples. Background Technology

[0002] Marine sediments refer to the general term for seabed sediments formed by various marine sedimentary processes. They are substances deposited on the seabed using seawater as the medium. Sedimentation processes can generally be divided into three different processes: physical, chemical, and biological. Because these processes often do not occur in isolation, sediments can be considered as geological bodies produced by a combination of processes. Traditionally, sediments are classified according to depth as: nearshore sediments (0–20 meters), shallow-sea sediments (20–200 meters), semi-deep-sea sediments (200–2000 meters), and deep-sea sediments (greater than 2000 meters).

[0003] Currently, the filtration and purification process for marine sediment samples can only remove water from the samples, making it difficult to remove stones or plastics. Marine sediments contain stones or plastics, and if these are not removed in time, it will affect the subsequent testing and processing of the sediments. During testing, these materials need to be picked out manually, which reduces the efficiency of the testing. Furthermore, it cannot perform layered cutting of the samples. Summary of the Invention

A rotating shaft 42 is rotatably connected to the bottom wall of the second moving nut block 19. 42 is powered by a rotating motor 41, which is fixedly installed inside the second moving nut block 19. A turntable 20 is fixedly installed on the outer surface of the rotating shaft 42. A first electric push rod 21 is fixedly installed on the bottom wall of the turntable 20.

Then, the second moving motor is started, causing the second moving lead screw 17 to rotate, which in turn moves the second moving nut block 19, thereby moving the turntable 20, which in turn moves the first electric push rod 21 to the corresponding position above the area where the sample contains stones or plastic. Power is then supplied to the first electric push rod 21, starting the rotating motor 41, which in turn rotates the rotating shaft 42, causing the first electric push rod 21 to rotate downwards, which in turn moves the arc plate 45 downwards, thereby causing the arc plate 45 to rotate to the corresponding depth. The electric shaft 44 is energized and rotated, which in turn drives the connecting block 46 to rotate, thereby causing the arc plate 45 to move and open, thus opening the sample containing stones or plastic. After opening, the second electric push rod 22 is energized and moves downward, thereby driving the fixed plate 68 to move downward, thereby driving the clamping nut plate 69 to move downward and contact the stones or plastic. The clamping electric screw 71 is energized and rotated, thereby driving the clamping nut plates 69 to move closer together, thereby driving the clamping anti-slip pad 72 to move and clamp the stones or plastic.

[0046] This starts the detection motor, which drives the detection lead screw 48 to rotate, which in turn drives the detection nut block 23 to move, which in turn drives the detection plate 24 to move, which in turn drives the X-ray detector 25 to move to detect the sample and determine the position of stones or plastics within the sample.

[0047] Advantageously, a sample placement mechanism is provided on the bottom wall of the filtration and purification chamber 14. The sample placement mechanism is used to place samples. The sample placement mechanism includes a placement groove 28 machined on the bottom wall of the filtration and purification chamber 14. A placement screw 29 is rotatably connected between the end walls of the placement groove 28. The placement screw 29 is poweredly connected to a placement motor.

A placement channel 8 is machined through the end wall of the filtration and purification chamber 14.

[0048] The placement motor is then activated, causing the placement screw 29 to rotate, which in turn moves the placement nut block 30, which in turn moves the groove frame 26, which in turn moves the lifting electric push rod 27, which in turn moves the placement rack 70. This causes the placement rack 70 to move out of the placement channel 8, and the sample is placed into the placement rack 70. The placement motor is then activated, causing the placement rack 70 to move into the filtration and purification chamber 14. After removing stones or plastic from the sample, the groove frame 26 is energized, causing the placement rack 70 to move upwards, bringing its bottom wall flush with the bottom wall of the conveying chamber 31.

[0050] When collecting stones, the first collecting motor is activated, which drives the first collecting screw 61 to rotate, thereby moving the first collecting nut 62. This causes the first collecting box 74 to move to the underside of the arc-shaped plate 45, where the arc-shaped plate 45 is in an open state. The clamping anti-slip pad 72 releases its grip on the stones, allowing them to fall into the first collecting box 74 for collection. When collecting plastic, the second collecting motor is activated, which drives the second collecting screw 65 to rotate, thereby moving the second collecting nut 64. This causes the second collecting box 75 to move to the underside of the arc-shaped plate 45, where the arc-shaped plate 45 is in an open state. The clamping anti-slip pad 72 releases its grip on the plastic, allowing the stones to fall into the second collecting box 75 for collection.

[0051] Advantageously, the housing 1 is equipped with a conveying mechanism for conveying the picked-out samples. The conveying mechanism includes a conveying cavity 31 within the housing 1, a conveying groove 32 on the bottom wall of the conveying cavity 31, a conveying screw 33 rotatably connected between the end walls of the conveying groove 32, and a conveying screw 33 poweredly connected to a conveying motor.

[0052] The conveying motor is then started, which drives the conveying screw 33 to rotate, thereby moving the conveying nut block 34. This causes the scooping plate 35 to move and insert into the placement rack 70, contacting the bottom wall of the placement rack 70 to scoop up the sample. After scooping, the scooping plate 35 resets. After resetting, the pushing motor is started, which drives the pushing screw 37 to rotate, thereby moving the pushing nut block 49. This causes the pushing plate 50 to move, thereby pushing the sample.

[0053] Advantageously, a dehydration mechanism is provided on the end wall of the housing 1. This mechanism is used to dehydrate the sample, facilitating sample research.

[0054] The pusher plate 50 pushes the sample to contact the dividing blade 55, thereby dividing the sample into upper and lower parts. The upper and lower parts enter the upper and lower dehydration chambers 6 respectively. The air drying device 3 is turned on, so that dry hot air enters the dehydration chamber 6 through the output pipe 5 and the first one-way valve 7, thereby dehydrating the sample in the dehydration chamber 6. The gas is then returned to the air drying device 3 through the second one-way valve 12 and the input pipe 4, thus realizing the cyclical dehydration of the sample.

[0056] When the sample enters the dehydration chamber 6, the first closed motor is started, which drives the first closed gear shaft 53 to rotate, which in turn drives the first closed gear 54 to rotate. The first closed gear 54 meshes with the first closed rack plate 51, which in turn drives the first closed rack plate 51 to move upward, thereby closing the dividing groove 76.

[0057] Advantageously, a second sealing mechanism is provided on the end wall of the dehydration chamber 6. The second sealing mechanism is used to seal or open the dehydration chamber 6 to facilitate dehydration or removal of the dehydrated sample. The second sealing mechanism includes a second sealing groove 13 on the end wall of the dehydration chamber 6. A second sealing gear cavity 59 is machined on the end wall of the second sealing groove 13. A second sealing gear shaft 58 is rotatably connected between the end walls of the second sealing gear cavity 59. The second sealing gear shaft 58 is poweredly connected to a second sealing motor. The second sealing motor is fixedly installed in the dehydration box 2. A second sealing gear 57 is fixedly installed on the outer surface of the second sealing gear shaft 58. The second sealing gear 57 meshes with a second sealing rack plate 56. The second sealing rack plate 56 is slidably installed between the end walls of the second sealing groove 13.

[0058] After dehydration is completed, the second closed motor is started, which drives the second closed gear shaft 58 to rotate, which in turn drives the second closed gear 57 to rotate. The second closed gear 57 meshes with the second closed rack plate 56, which in turn drives the second closed rack plate 56 to move, thereby opening the dehydration chamber 6 and facilitating the removal of the sample from the dehydration chamber 6.

[0059] Advantageously, a control panel 9 is fixedly connected to the housing 1, and an input panel 10 and a display panel 11 are fixedly installed on the control panel 9. The input panel 10, the display panel 11 and the control processor are signal connected. The control processor is fixedly installed in the control panel 9 and is signal connected to the telecommunications components in the device. The control processor has a corresponding control program.

[0060] The corresponding start command is input into the input panel 10. The input panel 10 inputs the command into the control processor. After processing, the control processor sends a signal to the corresponding component, causing the corresponding component to move. The information returned by the component is sent to the control processor, which then sends it to the display panel 11 for display.

[0061] This invention provides a method for filtering and purifying marine sediment samples, based on the aforementioned apparatus for filtering and purifying marine sediment samples, comprising the following steps:

[0062] Step 1: Power on the entire device;

[0063] Step 2: The sample placement mechanism moves to place the sample and move it into the filtration and purification chamber 14;

[0064] Step 3: After the sample enters the filtration and purification chamber 14, the detection mechanism moves to detect the sample, including stones and plastics.

[0065] Step 4: After testing, the filtration and purification mechanism moves to remove stones or plastic from the sample;

[0066] Step 5: The collecting mechanism moves to collect the picked-out stones or plastic.

[0067] Step Six: After filtration and purification, the conveying mechanism moves, thereby moving the sample to facilitate dehydration.

[0068] Step 7: After the sample enters the dehydration tank 2, the dehydration mechanism moves to dehydrate the sample;

[0069] Step 8: During dehydration, the first and second sealing mechanisms move to seal the dehydration chamber 6, facilitating better dehydration.

[0070] In the working process of this invention, a corresponding start command is input into the input panel 10. The input panel 10 inputs the command to the control processor. After processing, the control processor sends a signal to the corresponding component, causing the component to move. The information returned by the component is sent back to the control processor, which then sends it to the display panel 11 for display. The placement motor is started, thereby driving the placement lead screw 29 to rotate, which in turn drives the placement nut block 30 to move, which in turn drives the groove frame 26 to move, which in turn drives the lifting electric push rod 27 to move, which in turn drives the placement rack 70 to move out of the placement channel 8, placing the sample into the placement channel. In the placement frame 70, the placement motor is started, thereby driving the placement frame 70 to move and enter the filtration and purification chamber 14. After picking out stones or plastics from the sample, the groove frame 26 is energized, thereby driving the placement frame 70 to move upward, so that the bottom wall of the placement frame 70 is flush with the bottom wall of the conveying chamber 31. The detection motor is started, thereby driving the detection screw 48 to rotate, thereby driving the detection nut block 23 to move, thereby driving the detection plate 24 to move, thereby driving the X-ray detector 25 to move to detect the sample and determine the position of stones or plastics in the sample. The first moving motor is started, thereby driving the first moving screw 40 to rotate. The movement of the first moving nut block 16 causes the moving frame 15 to move to the corresponding position. The second moving motor is then activated, causing the second moving screw 17 to rotate, which in turn moves the second moving nut block 19, thereby moving the turntable 20. This, in turn, moves the first electric push rod 21 to the corresponding position, above the area where the sample contains stones or plastic. Power is then supplied to the first electric push rod 21, activating the rotating motor 41. This causes the rotating shaft 42 to rotate, which in turn causes the first electric push rod 21 to rotate downwards, thereby causing the arc-shaped plate 45 to rotate downwards, reaching the corresponding depth. Power is then supplied to the opening electric rotating shaft 44. The electric motor rotates, causing the connecting block 46 to rotate, which in turn moves the arc-shaped plate 45 to open up, thus opening up the sample containing stones or plastic. After opening, the second electric push rod 22 is energized to move downwards, causing the fixed plate 68 to move downwards, which in turn moves the clamping nut plate 69 downwards to contact the stones or plastic. The clamping electric screw 71 is energized to rotate, causing the clamping nut plates 69 to move closer together, which in turn moves the clamping anti-slip pad 72 to clamp the stones or plastic. The second electric push rod 22 is energized to move upwards, and at the same time, the picking motor 38 is activated, causing the second electric push rod 22 to rotate upwards, thereby picking out the stones or plastic from the sample.When collecting stones, the first collecting motor is started, which drives the first collecting screw 61 to rotate, thereby moving the first collecting nut 62. This causes the first collecting box 74 to move to the underside of the arc-shaped plate 45, where the arc-shaped plate 45 is in an open state. The clamping anti-slip pad 72 releases its grip on the stones, allowing them to fall into the first collecting box 74 for collection. When collecting plastic, the second collecting motor is started, which drives the second collecting screw 65 to rotate, thereby moving the second collecting nut 64. This causes the second collecting box 75 to move to the underside of the arc-shaped plate 45, where the arc-shaped plate 45 is in an open state. In the open state, the clamping anti-slip pad 72 releases its grip on the plastic, allowing the stones to fall into the second collection box 75 for collection. The conveying motor is then activated, causing the conveying screw 33 to rotate, which in turn moves the conveying nut block 34, causing the shovel plate 35 to move and insert into the placement rack 70, contacting the bottom wall of the rack to shovel the sample. After shoveling, the shovel plate 35 returns to its original position. Upon returning to its original position, the pushing motor is activated, causing the pushing screw 37 to rotate, which in turn moves the pushing nut block 49, which in turn moves the pushing plate 50, thus pushing the sample forward. The pusher plate 50 pushes the sample to contact the dividing blade 55, thereby dividing the sample into upper and lower parts. The upper and lower parts respectively enter the upper and lower dehydration chambers 6. The air drying device 3 is turned on, allowing dry hot air to enter the dehydration chamber 6 through the output pipe 5 and the first one-way valve 7, thus dehydrating the sample in the dehydration chamber 6. The remaining gas is then returned to the air drying device 3 through the second one-way valve 12 and the input pipe 4, thus achieving cyclical dehydration of the sample. When the sample enters the dehydration chamber 6, the first closed motor is started, thereby... The first closed gear shaft 53 is rotated, thereby driving the first closed gear 54 to rotate. The first closed gear 54 meshes with the first closed rack plate 51, thereby driving the first closed rack plate 51 to move upward, thus closing the dividing groove 76. After dehydration is completed, the second closed motor is started, thereby driving the second closed gear shaft 58 to rotate, thereby driving the second closed gear 57 to rotate. The second closed gear 57 meshes with the second closed rack plate 56, thereby driving the second closed rack plate 56 to move, thus opening the dehydration chamber 6, facilitating the removal of the sample from the dehydration chamber 6.
