The water outlet pipe at the bottom of the material bin is sealed by an adjustment block and a blocking block when not in operation. This mechanism maintains a closed environment inside the material bin to prevent moisture, dust or microorganisms from contaminating the adsorption material, ensuring that subsequent analysis data is true and reliable, while also avoiding contamination of samples during subsequent storage and transportation.

[0018] 3. The filtration treatment component adopts an innovative structure to achieve self-cleaning, effectively intercept impurities and periodically discharge pollutants to prevent blockage and reduce downtime for maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] like Figures 1 to 10 As shown, a multi-bin circulating seawater enrichment device includes a cylinder 1, a cylinder cover 2, and several material bins 3. A mounting frame 4 and a main shaft 5 are provided at the lower part of the cylinder 1. One end of the main shaft 5 is fixed to the middle of the mounting frame 4, and the other end is rotatably connected to the bottom end of the cylinder 1. The main shaft 5 is driven to rotate by a first motor 6 disposed in the cylinder 1. The mounting frame 4 is provided with several fixing openings for the material bins 3 to pass through. The material bins 3 are detachably fixed to the mounting frame 4.

[0032] The upper part of the cylinder 1 is provided with a bracket 7, a water pump 8, a screw 9, a second motor 10 and a water inlet pipe 11. The upper end of the bracket 7 is fixed to the cylinder cover 2. The second motor 10 and the water pump 8 are both arranged on the bracket 7. The screw 9 is rotatably assembled on the bracket 7 and is transmission-connected with the second motor 10. An adjustment bracket 12 is vertically slidably assembled on the bracket 7. The adjustment bracket 12 is threadedly connected to the screw 9. The water inlet pipe 11 is fixed to the adjustment bracket 12. The cylinder cover 2 is provided with a water supply pipe 13. The water supply pipe 13 is connected to the input end of the water pump 8 through a pipe, and the output end of the water pump 8 is connected to the water pump 8 through a soft The pipe is connected to the upper end of the water inlet pipe 11, and a number of sealing rings 14 are provided on the outer periphery of the water inlet pipe 11 (sealed by the sealing ring 14 to prevent water from flowing back due to the small outlet of the material bin, and to prevent water vapor from entering the cylinder 1 and causing rust to the equipment). The water inlet pipe 11 is driven by the screw rod 9 to descend to the inside of the material bin 3 and then water is passed through to form a water inlet station. A reflux port 48 is provided at the bottom end of the cylinder 1 corresponding to the water inlet station; a flow meter and an infrared sensor are provided on the bracket 7. The flow meter is used to monitor the seawater flow rate, and the infrared sensor is used to detect the displacement of the water inlet pipe.

[0033] A sealing assembly is provided on the top of the material bin 3. The sealing assembly automatically opens when the water inlet pipe 11 enters, and automatically seals and closes after the water inlet pipe 11 leaves. A filtering and processing assembly 49 is provided on the water supply pipe 13. The filtering and processing assembly 49 is used to intercept impurities in seawater and periodically discharge sewage to achieve impurity cleaning.

[0034] In this embodiment, the sealing assembly includes two symmetrically arranged covers 15, the covers 15 are semicircular in structure, the covers 15 are hingedly assembled on the opening of the material bin 3, and a torsion spring is connected between the covers 15 and the material bin 3. In the initial state, the two covers 15 are spliced ​​together by the torsion spring to form a complete sealing surface, which is adapted to the shape and size of the opening of the material bin 3. A sealing strip is provided on the side of the cover 15; a water outlet pipe 16 is provided at the bottom of the material bin 3, a sealing plate 17 is provided in the water outlet pipe 16, a water outlet 18 is provided in the middle of the sealing plate 17, and a rubber ring is embedded in the inner wall of the water outlet 18 to allow water to flow out. An adjusting block 19 is slidingly assembled in the tube 16. The adjusting block 19 is located below the sealing plate 17. A blocking block 20 that is compatible with the water outlet 18 is provided on the top of the adjusting block 19, and a number of water outlets 21 are opened around the blocking block 20. An adjusting port 22 is opened on the side wall of the outlet pipe 16. A guide rod 23 is provided on the side end of the adjusting block 19. The guide rod 23 passes through the adjusting port 22 and extends to the outside. A "V"-shaped guide frame 24 is provided on the inner wall of the lower part of the cylinder 1 corresponding to the water inlet position. When the guide rod 23 rotates to the water inlet position with the material bin 3, it moves downward along the inclined surface of the guide frame 24, driving the adjusting block 19 to move downward to open the water outlet 18.

[0035] The working principle of this device is as follows: First, a water pipe is connected to the water inlet pipe 11, and the other end of the water pipe is connected to the sea. The first motor 6 drives the main shaft 5 to rotate, driving the mounting frame 4 and the multiple material bins 3 fixed thereon to rotate synchronously. The material bins 3 move with the turntable to the water inlet position (facing the water inlet pipe 11 and the return port 48). The infrared sensor accurately locates the position. At the same time, when the material bins 3 rotate to the water inlet position, the guide rod 23 enters the guide frame 24 and slides down along the "V"-shaped guide frame 24 slope, thereby pushing the adjustment block 19 downward, so that the blocking block 20 is separated from the water port 18 to open the water outlet channel;

[0036] At the start of enrichment, the second motor 10 drives the screw 9 to rotate, and the adjustment frame 12 drives the water inlet pipe 11 to move vertically downward. The water inlet pipe 11 descends and squeezes the cover 15. The double semicircular cover 15 separates and opens the port, allowing the water inlet pipe 11 to be inserted into the material bin 3 (each material bin 3 is filled with adsorption material, and the adsorption material in each material bin 3 can be set to be different). When it reaches the set depth, it automatically stops, and then the water pump 8 starts working (water flow direction: nautical miles - water inlet pipe 11 - water pump 8 - inlet - material bin 3 - nautical miles). As the seawater passes through the material bin 3, the elements in it are adsorbed by the adsorption material in the material bin 3. The flow rate is monitored by the flow meter to control the current flowing through the water pump 8, thereby controlling the pumping speed of the water pump 8, and completing the flow rate control of the entire equipment, which is designed to be 1 L / min. After the enrichment of the material bin 3 is completed, the current state will be retained. At the beginning of the next enrichment, the water inlet pipe 11 will move up and then be controlled to rotate to the next material bin 3, and the enrichment cycle will continue.

[0037] After the enrichment is completed in the material bin 3 and the water inlet pipe 11 leaves the material bin 3, the cover 15 will be reset and closed under the action of the torsion spring. At the same time, as the material bin 3 rotates to the next workstation, the adjustment block 19 at the bottom will also move upward under the action of the guide frame 24, so that the blocking block 20 can re-block the water outlet 18. At this time, the material bin 3 forms a sealed structure to prevent external air from infiltrating. Therefore, after the enriched material completes the experiment, the target substance has been adsorbed on its surface or in its pores. If exposed to the air, it will be contaminated by humidity, dust or microorganisms, resulting in distortion of subsequent analysis data, and high-salinity seawater may remain in the material bin 3. If it is not sealed, the liquid will seep out due to centrifugal force during rotation to produce salt mist, which will corrode metal parts such as motors and bearings.

[0038] In this embodiment, an iron sheet 25 is embedded in the top surface of the sealing cover 15, and an adsorption assembly is provided in the cylinder body 1. The adsorption assembly includes a support frame 26, a first telescopic cylinder, an electromagnet 28 and a support 29. The first telescopic cylinder is fixed to the bottom of the cylinder cover 2 and is located downstream of the water inlet station. The piston end of the first telescopic cylinder is provided with a support frame 26, and a plurality of slide rods 27 are provided on the support frame 26. The support 29 is slidably assembled on the slide rods 27, and a first spring 30 is connected between the top of the support 29 and the support frame 26. The electromagnet 28 is installed at the bottom of the support 29. When it is energized, it generates a magnetic attraction force acting on the iron sheet 25 on the sealing cover 15;

[0039] When the water inlet pipe 11 moves up and leaves the material bin 3, the cover 15 will rebound and reset under the action of the restoring force of the torsion spring, but the restoring force of the torsion spring is limited, and it is difficult to ensure that there will be a rebound gap between the two covers 15, or due to the friction of the sealing strip, it cannot be ensured that it is completely rotated to the horizontal position and closed. At this time, when the material bin 3 moves to the next workstation, the first telescopic cylinder drives the electromagnet 28 to move down, and at the same time the electromagnet 28 is energized to adsorb the iron sheets 25 on the two covers 15, and then the first telescopic cylinder drives the electromagnet 28 to move up, thereby vertically lifting the cover 15, so that the cover 15 is pulled to the horizontal position, and at the same time, the sealing strips on the two covers 15 can be squeezed and fitted together, thereby ensuring that the two covers 15 are completely closed horizontally. The design of the first spring 30 is to form a buffer distance, so as to avoid damage to the cover 15 caused by the rigid lifting force of the first telescopic cylinder.

[0040] In this embodiment, an annular block 31 is rotatably sleeved on the top of the material bin 3, and a gear 32 is sleeved on the outer circumference of the annular block 31. An arc-shaped rack 33 is provided on the inner wall of the cylinder 1, and the arc-shaped rack 33 is located in the downstream direction of the first telescopic cylinder. A groove 34 is provided on the left and right ends of the inner wall of the annular block 31, and a clamping block 35 is slidably provided in the groove 34, and a second spring 36 is connected between the clamping block 35 and the inner wall of the groove 34. One end of the clamping block 35 is a slope structure, and a through hole 37 is provided on the left and right ends of the top of the material bin 3; in the initial state, the top surface of the through hole 37 is in the same horizontal plane as the bottom surface of the sealing cover 15. When the annular block 31 rotates until the groove 34 aligns with the through hole 37, the clamping block 35 moves radially inward under the action of the second spring 36, embeds into the through hole 37 and extends to the bottom of the sealing cover 15 to form a mechanical lock;

[0041] After the electromagnet 28 is attracted and closed, when the main shaft 5 rotates for the next time, the electromagnet 28 is de-energized and the adsorption is cancelled; the gear 32 on the annular block 31 of the material bin 3 meshes with the arc-shaped rack 33, and then as the material bin 3 rotates, the arc-shaped rack 33 drives the annular block 31 to rotate, and finally when it rotates to the next station, the groove 34 aligns with the through-hole 37 below the cover 15, and the block 35 is pushed by the second spring 36 to slide into the through-hole 37, thereby pressing against the bottom surface of the cover 15 to form a mechanical lock. At this time, the cover 15 is limited by the block 35 and cannot be opened downward, thereby locking the cover 15 that has been attracted and closed by the electromagnet 28 to prevent the cover 15 from loosening due to equipment vibration or subsequent transportation;

[0042] When opening is required, the annular block 31 only needs to be rotated in the opposite direction, the groove 34 and the through-opening 37 are misaligned, and the inclined guide structure of the clamping block 35 is automatically retracted into the groove 34 when being squeezed by the through-opening 37.

[0043] In this embodiment, the filtering treatment component 49 includes a second telescopic cylinder 38, a filter screen 39 and a bracket 40. The second telescopic cylinder 38 is assembled on the cylinder cover 2. A plurality of connecting rods 41 are provided at the bottom end of the bracket 40. The other end of the connecting rod 41 is connected to a bracket 42 that is adapted to the inner diameter of the water supply pipe 13. The filter screen 39 has a conical structure. The filter screen 39 is installed at the upper end of the bracket 42. The bracket 42 has an opening for water flow to pass through. A mounting port is provided in the middle of the bracket 40. A water pipe 43 is embedded in the mounting port. The upper and lower ends of the water pipe 43 extend out of the upper and lower sides of the bracket 40 respectively. The outer diameter of the water pipe 43 is adapted to the inner diameter of the water supply pipe 13 and a sealing ring is provided at the lower part of the water pipe 43. The activity of the second telescopic cylinder 38 The plug rod is connected to the bracket 42, and the second telescopic cylinder 38 drives the bracket 42 to rise and fall, driving the filter 39 to switch its position in the water supply pipe 13; the outer circumferential surface of the water supply pipe 13 is rotatably sleeved with an annular rotating seat 44, and the second telescopic cylinder 38 is installed on the rotating seat 44. The cylinder cover 2 is equipped with a third motor 45, and the third motor 45 is transmission-connected to the rotating seat 44 to drive the rotating seat 44 to rotate. The connecting rod 41 is in sliding contact with the inner wall of the water supply pipe 13, and the bracket 42 is slidably assembled on the inner wall of the water supply pipe 13. The top surface of the bracket 42 is rotatably provided with an annular support plate 46, and the support plate 46 can rotate around the central axis of the bracket 42. The connecting rod 41 is connected to the support plate 46, and a scraper 47 is provided on the connecting rod 41, and the scraper 47 is in contact with the surface of the filter 39.

[0044] During operation, the water pipe that flows into the seawater is installed on the water guide pipe 43. When the seawater flows in, impurities in the seawater (such as algae, shellfish, etc.) will be filtered out when flowing through the filter screen 39. The filter screen 39 is conical in shape, which can effectively increase the filtering area. At the same time, since the water flows from the bottom of the cone to the top of the cone, impurities will accumulate at the top of the cone and will not clog the entire filter screen 39; when the impurities in the water supply pipe 13 accumulate to a certain amount, the sewage discharge work is started, and the third motor 45 first drives the rotating seat 44 to rotate, so that the connecting rod 41 and the scraper 47 thereon rotate to scrape off the impurities attached to the inner wall of the water supply pipe 13 and the filter screen 39, and then the second telescopic cylinder 38 drives the support seat 42 to rise, driving the scraped impurities out of the water supply pipe 13. After leaving the water supply pipe 13, the impurities will automatically fall outward due to the conical structure of the filter screen 39 and the action of gravity (a collection tray can be set on the outside to collect the fallen impurities). At this time, the third motor 45 can drive the rotating seat 44 to rotate slowly, thereby throwing out the remaining impurities through centrifugal force; after completing the sewage discharge work, the second telescopic cylinder 38 drives the water pipe 43 to be reinserted into the water supply pipe 13.
