Description

Technical Field

[0001] This invention relates to the field of sea sand desalination technology, specifically to a sea sand desalination system and method. Background Technology

[0002] Sea sand refers to sand that has been eroded by seawater and has not undergone desalination treatment. It mostly comes from areas where seawater and rivers meet, and is the second largest marine mineral resource after oil and natural gas. It has numerous uses, one of its main applications being as a raw material for engineering construction. Desalination removes excess impurities (likely chloride ions) from sea sand, making it usable as building sand and improving its usability. Sea sand desalination requires specific equipment and processes. During desalination, a heating device is needed; however, current heating devices cannot agitate the sea sand at the bottom of the heating chamber, resulting in uneven heating and mixing of the sea sand and dechlorinating agent, thus affecting the dechlorination effect.

[0010] Optionally, an exhaust valve is installed on the top of the absorption box, and an air pipe is installed on the top of the heating box, with one end of the air pipe extending into the interior of the absorption box.

[0011] The method for desalination of sea sand includes the following steps:

[0012] Step 1: Sea sand falls onto the surface of the conveying module through the feeding module, is then conveyed into the feeding hopper, and finally falls into the heating chamber. The dosing module discharges the dechlorinating agent into the heating chamber. Next, the stirring assembly starts, mixing the dechlorinating agent and sea sand. During mixing, the output of one second servo motor drives the first winding roller to rotate, and the output of another second servo motor drives the second winding roller to rotate, causing the second winding roller to wind up the second winding rope while the first winding roller releases the first winding rope. Simultaneously, the output of the fifth servo motor drives the third winding roller to rotate. As the scraper moves the slider, one shielding cloth is gradually released while another shielding cloth is gradually wound up, pushing the sea sand on top of the sealing seat towards the second side groove. The sea sand enters through the second side groove, guide box, guide hopper, and switch valve. The sea sand is fed into the conveying cylinder, and then the output of the third servo motor drives the screw conveyor shaft to rotate, causing the screw conveyor shaft to push the sea sand upwards. The sea sand is then discharged into the heating chamber through the inlet pipe. When the scraper moves to the designated position, the output of one second servo motor drives the first take-up roller to reset and rotate, and the output of another second servo motor drives the second take-up roller to reset and rotate. The first take-up roller winds up the first take-up rope, and the second take-up roller releases the second take-up rope. The first take-up rope pulls the scraper to move towards the first side groove. The sea sand enters the conveying cylinder through the first side groove, guide box, guide bucket, and switch valve. Then, the output of the third servo motor drives the screw conveyor shaft to rotate, causing the screw conveyor shaft to push the sea sand upwards. The sea sand is then discharged into the heating chamber through the inlet pipe, thus mixing is performed.

[0013] Step 2: The chlorine gas generated by the mixing of dechlorinating agent and sea sand inside the heating chamber enters the absorption tank through the gas pipe. The first pump draws in the chlorine-absorbing liquid from the external liquid storage device, and then discharges it into the second guide plate through the main pipe. It is then sprayed out through the nozzle, allowing the chlorine-absorbing liquid to come into contact with the chlorine gas and absorb it. The gas moves through the gas path composed of the nozzle and the three first guide plates. The chlorine-absorbing liquid enters the branch pipe through the main pipe, then enters the drive tank through the impact blade, then enters the nozzle through the drive tank, and finally sprays out through the nozzle. When the liquid flows in the drive tank, the liquid pushes the fan blade to move, causing the fan blade to drive the rotating rod to rotate. The rotating rod then drives the connecting pipe to rotate, so that the gas hits the connecting pipe and comes into full contact with the liquid sprayed from the nozzle, thereby absorbing the chlorine gas. The liquid that has absorbed the chlorine gas falls to the bottom of the absorption tank cavity, and can be extracted by the second pump and then discharged into the external subsequent processing equipment. The dechlorinated gas is discharged into the subsequent processing equipment through the exhaust valve.

[0014] Step 3: After the sea sand inside the heating chamber is processed, the switch valve is closed. The output end of the first servo motor drives the lead screw to rotate, causing the top of the sealing seat to move out of the sealing groove. Then, the extension end of the electric telescopic rod drives the bottom box to move to one side of the heating chamber, causing the sea sand inside the heating chamber to fall into the filter module. At the same time, the output end of the third servo motor drives the spiral conveyor shaft to rotate, discharging the sea sand inside the conveying cylinder into the heating chamber through the inlet pipe.

[0015] Step 4: The sea sand falls into the collection box through the filtration module for filtration, then falls into the dewatering module for screening, and finally the treated sea sand is discharged.

[0016] This invention provides a sea sand desalination system and method, which have the following beneficial effects:

[0017] 1. This sea sand desalination system and method, equipped with a scraper, a first winding rope, and a second winding rope, involves the following process: During mixing, the output of one second servo motor drives the first winding roller to rotate, and the output of another second servo motor drives the second winding roller to rotate. This causes the second winding roller to wind up the second winding rope, while the first winding roller releases the first winding rope, pushing the sea sand at the top of the sealing seat towards the second side trough. The sea sand then enters the conveying cylinder through the second side trough, guide box, guide hopper, and switch valve. Finally, the output of a third servo motor drives the screw conveyor shaft to rotate, causing the screw... The conveyor shaft pushes the sea sand upwards, allowing it to be discharged into the heating chamber through the inlet pipe. When the scraper moves to the designated position, the output of one second servo motor drives the first take-up roller to reset and rotate, and the output of another second servo motor drives the second take-up roller to reset and rotate. This causes the first take-up roller to wind up the first take-up rope, and the second take-up roller to release the second take-up rope. This causes the first take-up rope to pull the scraper towards the first side groove, which can discharge the sea sand at the bottom of the heating chamber to the top of the heating chamber, making the sea sand and dechlorinator mix more evenly and improving the reaction effect between the sea sand and the dechlorinator.

[0018] 2. This sea sand desalination system and method comprises an absorption tank, a first guide plate, and a second guide plate. Chlorine gas generated from the mixing of dechlorinating agent and sea sand inside the heating chamber enters the absorption tank through a gas pipe. A first pump draws in chlorine-absorbing liquid from an external storage device, then discharges it through a main pipe into the second guide plate and is ejected through nozzles, allowing the chlorine-absorbing liquid to contact and absorb the chlorine. The gas moves through a gas path formed by the nozzles and the three first guide plates. The chlorine-absorbing liquid enters a branch pipe through the main pipe, then enters a drive tank through an impact blade, then enters a nozzle, and finally is ejected through the nozzle. As the liquid flows within the drive tank, it drives the fan blades, causing them to rotate a rotating rod. This rotating rod then rotates a connecting pipe, allowing the gas to impact the connecting pipe and fully contact the liquid ejected from the nozzle, thus absorbing the chlorine. The liquid, after absorbing the chlorine, falls to the bottom of the absorption tank, ensuring continued contact between the chlorine-absorbing liquid and the chlorine gas for further absorption.

[0038] Example 2

[0039] Please see Figures 1 to 9 This invention provides a technical solution: a method for desalination of sea sand, comprising the following steps:

[0040] Step 1: Sea sand falls onto the surface of the conveying module 3 through the feeding module 2, is conveyed to the inside of the feeding hopper 13 through the conveying module 3, and then falls into the heating chamber 10. The dosing module 12 discharges the dechlorinating agent into the heating chamber 10. Then, the stirring assembly 11 is started to mix the dechlorinating agent and the sea sand. During mixing, the output of one second servo motor 25 drives the first winding roller 21 to rotate, and the output of another second servo motor 25 drives the second winding roller 27 to rotate, so that the second winding roller 27 winds up the second winding rope 28, and the first winding roller 21 releases the first winding rope 23. At the same time, the output of the fifth servo motor 57 drives the third winding roller 52 to rotate. As the scraper 24 drives the slider 55 to move, one shielding cloth 53 is gradually released and the other shielding cloth 53 is gradually wound up, pushing the sea sand on the top of the sealing seat 18 towards the second side groove 29. The sea sand enters the heating chamber 10 through the second side groove 29, the guide box 30, the guide hopper 31 and the switch valve 32. Inside the conveying cylinder 33, the output of the third servo motor 35 drives the spiral conveying shaft 34 to rotate, causing the spiral conveying shaft 34 to push the sea sand upwards, so that the sea sand is discharged into the heating chamber 10 through the inlet pipe 56. When the scraper 24 moves to the designated position, the output of one second servo motor 25 drives the first winding roller 21 to reset and rotate, and the output of another second servo motor 25 drives the second winding roller 27 to reset and rotate, so that the first winding roller 21 winds up the first winding rope 23, and the second winding roller 27 releases the second winding rope 28, so that the first winding rope 23 pulls the scraper 24 to move towards the first side groove 22. The sea sand enters the conveying cylinder 33 through the first side groove 22, guide box 30, guide bucket 31 and switch valve 32, and then the output of the third servo motor 35 drives the spiral conveying shaft 34 to rotate, so that the spiral conveying shaft 34 pushes the sea sand upwards, so that the sea sand is discharged into the heating chamber 10 through the inlet pipe 56, thus mixing.

[0041] Step Two: The chlorine gas generated by the mixing of dechlorinating agent and sea sand inside the heating chamber 10 enters the absorption tank 37 through the gas pipe 36. The first pump 48 draws in the chlorine-absorbing liquid from the external storage device, and then discharges it into the second guide plate 39 through the main pipe 47. It is then sprayed out through the nozzle 40, allowing the chlorine-absorbing liquid to come into contact with the chlorine gas and absorb it. The gas moves through the gas path formed by the nozzle 40 and the three first guide plates 38. The chlorine-absorbing liquid enters the branch pipe 41 through the main pipe 47, and then enters the drive tank 42 through the impeller 45. Finally, it enters the... Inside the nozzle 46, the liquid is finally sprayed out through the nozzle 46. When the liquid flows inside the drive tank 42, the liquid pushes the fan blade to move, causing the fan blade to drive the rotating rod 43 to rotate, causing the rotating rod 43 to drive the connecting pipe 44 to rotate, so that the gas hits the connecting pipe 44 and makes full contact with the liquid sprayed from the nozzle 46, thereby absorbing the chlorine. The liquid that has absorbed the chlorine falls to the bottom of the inner cavity of the absorption tank 37, and can be extracted by the second pump 49 and then discharged into the external subsequent processing equipment. The dechlorinated gas is discharged into the subsequent processing equipment through the exhaust valve 50.

[0042] Step 3: After the sea sand treatment inside the heating box 9 is completed, the switch valve 32 is closed, the output end of the first servo motor 17 drives the lead screw 16 to rotate, so that the top of the sealing seat 18 moves out of the sealing groove 19. Then, the telescopic end of the electric telescopic rod 14 drives the bottom box 15 to move to one side of the heating box 9, so that the sea sand inside the heating chamber 10 falls into the filter module 6. At the same time, the output end of the third servo motor 35 drives the spiral conveyor shaft 34 to rotate, so that the sea sand inside the conveying cylinder 33 is discharged into the heating chamber 10 through the inlet pipe 56.

[0043] Step 4: The sea sand falls into the collection box 7 through the filtration module 6 for filtration, then falls into the dewatering module 8 through the collection box 7 for screening, and finally the treated sea sand is discharged.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

7. A sea sand desalination method based on the sea sand desalination system described in claims 1-6, characterized in that: Includes the following steps: Step 1: Sea sand falls onto the surface of the conveying module (3) through the feeding module (2), and is then conveyed to the inside of the feeding hopper (13) through the conveying module (3), and then falls into the heating chamber (10). The dosing module (12) discharges the dechlorinating agent into the heating chamber (10). Then the stirring assembly (11) is started to mix the dechlorinating agent and the sea sand. During the mixing, the output end of one second servo motor (25) drives the first winding roller (21) to rotate, and the output end of another second servo motor (25) drives the second winding roller (27) to rotate, so that... The second take-up roller (27) takes up the second take-up rope (28), and the first take-up roller (21) releases the first take-up rope (23). At the same time, the output end of the fifth servo motor (57) drives the third take-up roller (52) to rotate. As the scraper (24) drives the slider (55) to move, one shielding cloth (53) is gradually released, and the other shielding cloth (53) is gradually taken up, pushing the sea sand on the top of the sealing seat (18) toward the second side groove (29). The sea sand enters through the second side groove (29), guide box (30), guide bucket (31) and switch valve (32) to Inside the conveying cylinder (33), the output of the third servo motor (35) drives the spiral conveying shaft (34) to rotate, causing the spiral conveying shaft (34) to push the sea sand upward, so that the sea sand is discharged into the heating chamber (10) through the inlet pipe (56). When the scraper (24) moves to the designated position, the output of one second servo motor (25) drives the first winding roller (21) to reset and rotate, and the output of another second servo motor (25) drives the second winding roller (27) to reset and rotate, so that the first winding roller (21) winds up the first winding rope (27). 3) The second take-up roller (27) releases the second take-up rope (28), causing the first take-up rope (23) to pull the scraper (24) to move towards the first side groove (22). The sea sand enters the conveying cylinder (33) through the first side groove (22), guide box (30), guide bucket (31) and switch valve (32). Then, the output end of the third servo motor (35) drives the screw conveyor shaft (34) to rotate, causing the screw conveyor shaft (34) to push the sea sand upward, so that the sea sand is discharged into the heating chamber (10) through the inlet pipe (56) for mixing. Step 2: The chlorine gas generated by the mixing of dechlorinating agent and sea sand inside the heating chamber (10) enters the absorption tank (37) through the gas pipe (36). The first pump (48) draws in the chlorine-absorbing liquid from the external storage device, and then discharges it into the second guide plate (39) through the main pipe (47). It is then sprayed out through the nozzle (40), so that the chlorine-absorbing liquid comes into contact with the chlorine gas and absorbs the chlorine gas. The gas moves through the gas path composed of the nozzle (40) and the three first guide plates (38). The chlorine-absorbing liquid enters the branch pipe (41) through the main pipe (47), and then enters the drive tank (42) through the impeller (45). Then it passes through the drive tank (42) The liquid enters the nozzle (46) and is finally sprayed out through the nozzle (46). When the liquid flows inside the drive tank (42), the liquid pushes the fan blade to move, causing the fan blade to drive the rotating rod (43) to rotate, causing the rotating rod (43) to drive the connecting pipe (44) to rotate, so that the gas hits the connecting pipe (44) and comes into full contact with the liquid sprayed out by the nozzle (46), thereby absorbing the chlorine. The liquid after absorbing the chlorine falls to the bottom of the absorption box (37) and is extracted by the second pump (49) and then discharged into the external subsequent processing equipment. The dechlorinated gas is discharged into the subsequent processing equipment through the exhaust valve (50). Step 3: After the sea sand treatment inside the heating box (9) is completed, the switch valve (32) is closed, the output end of the first servo motor (17) drives the screw (16) to rotate, so that the top of the sealing seat (18) moves out of the sealing groove (19), and then the extension end of the electric telescopic rod (14) drives the bottom box (15) to move to one side of the heating box (9), so that the sea sand inside the heating chamber (10) falls into the filter module (6), and at the same time, the output end of the third servo motor (35) drives the spiral conveying shaft (34) to rotate, so that the sea sand inside the conveying cylinder (33) is discharged into the heating chamber (10) through the inlet pipe (56); Step 4: The sea sand falls into the collection box (7) through the filtration module (6) for filtration, and then falls into the dewatering module (8) through the collection box (7) for screening. Finally, the treated sea sand is discharged.
