Description

Technical Field

[0001] This utility model relates to the field of sea sand desalination technology, and more specifically to a modular sea sand rapid desalination device. Background Technology

[0002] Sand is an essential component of concrete. With rapid economic development, the demand for concrete is gradually increasing, and the demand for sand is also surging. Compared with river sand, sea sand has abundant reserves, good gradation, and is easy to mine. my country has abundant sea sand resources and large reserves. After desalination, it can be used as construction sand, making it the best alternative to solve the shortage of river sand resources. However, sea sand has a high chloride content. If chlorides on its surface and in its internal crevices are not effectively and sufficiently removed, it will have a significant impact on the durability of reinforced concrete, leading to potential safety hazards in engineering quality. Among existing technologies, the most commonly used desalination techniques for sea sand are freshwater rinsing and freshwater rinsing combined with mechanical methods. However, these two technologies have long processing times, large equipment footprints, and complex processing procedures, resulting in low chloride ion removal efficiency or inability to effectively remove the biofilm on the surface of sea sand, leading to the slow release of chloride ions in the later stages.

[0003] Chinese Patent Publication No. CN117776575A discloses a rapid desalination system and process for sea sand. The process includes the following steps: S1, pouring sea sand raw material into a feed hopper and transporting it to a screening device via a conveyor belt for screening; S2, transporting the sea sand through the screening device to a first wheel sand washing machine via a conveyor belt for pretreatment to obtain coarse finished sea sand; S3, transporting the coarse finished sea sand to a spiral sand washing machine via a conveyor belt for a first rinsing process to obtain semi-finished sea sand; S4, transporting the semi-finished sea sand to a second wheel sand washing machine, adding nano-gaseous oxidant to the sea sand, and performing a second rinsing process to obtain finished sea sand. S5. The finished sea sand is transported to a vibrating dewatering screen via a conveyor belt for dewatering to obtain commercial sea sand. The above-mentioned treatment process uses nano-gaseous oxidants to clean and oxidize the biofilm and chlorides in the crevices of the sea sand surface, achieving rapid and efficient removal of chloride ions. However, it suffers from problems such as excessively long equipment length, large space occupation, and ineffective utilization of water in the dewatering process. Therefore, we propose a modular rapid desalination treatment device for sea sand. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1: Please see Figure 1-6 This utility model provides a technical solution: a modular sea sand rapid desalination device, including a steel frame 1, a drum screen group 2 fixedly connected to one side of the upper end of the steel frame 1, an ultrasonic electrolysis group 4 fixedly connected to the other side of the upper end of the steel frame 1, a return water pipe 3 fixedly connected to the upper rear side of the ultrasonic electrolysis group 4, a nano-oxidation reaction mechanism 5 fixedly connected to the lower left side of the steel frame 1, the end of the return water pipe 3 away from the ultrasonic electrolysis group 4 fixedly connected to the lower side of the nano-oxidation reaction mechanism 5, and the lower side of the ultrasonic electrolysis group 4 fixedly connected to the upper right side of the nano-oxidation reaction mechanism 5. The drum screen assembly 2 includes a base plate 21. A first support rod 22 with front and rear symmetrical arrangement is rotatably connected to the upper left side of the base plate 21. A second support rod 24 with front and rear symmetrical arrangement is rotatably connected to the upper right side of the base plate 21. A connecting plate 23 is provided on the upper surface of the two first support rods 22 and the upper surface of the two second support rods 24. A double-drum variable angle drum screen 26 is rotatably connected to the middle of the upper surface of the connecting plate 23. Rotators 25 with front and rear symmetrical arrangement are fixedly connected to the left and right sides of the upper end of the connecting plate 23. The outer surfaces of the four rotors 25 are in contact with the outer surface of the double-drum variable angle drum screen 26.

[0019] It should be noted that the specific installation method, circuit connection method, and control method of the rotator 25 in this utility model are all conventional designs and are standard design methods used by designers. The rotator 25 consists of a rotating base, a servo motor, and a rotating wheel. The rotating wheel is in contact with the outer surface of the double-drum variable angle drum screen 26. When the rotating wheel is driven to rotate by the servo motor, it will drive the double-drum variable angle drum screen 26 to rotate on the connecting plate 23. In addition, the double-drum variable angle drum screen 26 has a built-in corrugated screen to improve screening efficiency and reduce clogging. Furthermore, the connecting plate 23 can rotate at a certain angle around the two support rods 22 with the two support rods 22 as the axis. By changing the length of the second support rod 24, the angle between the rotator 25 and the connecting plate 23 can be changed, thereby achieving the purpose of changing the angle of the double-drum variable angle drum screen 26.

[0020] The ultrasonic electrolysis unit 4 includes a housing 41. An ultrasonic cleaning tank 43 is provided on the upper right side of the housing 41. A positive electrode 42 is provided on the left side of the inner cavity of the ultrasonic cleaning tank 43, and a negative electrode 44 is provided on the right side of the inner cavity of the ultrasonic cleaning tank 43. An auger component 46 is fixedly connected to the lower right side of the housing 41. A drive motor 45 is fixedly connected to the right end of the auger component 46. A discharge port 47 is fixedly connected to the lower left side of the outer surface of the auger component 46. The lower end of the housing 41 is fixedly connected to the upper left side of the steel frame 1. The inner cavity of the ultrasonic cleaning tank 43 is connected to the inner cavity of the return water pipe 3.

[0021] First, it should be noted that the specific installation methods, circuit connections, and control methods of the drive motor 45, positive electrode 42, and negative electrode 44 in this utility model are all conventional designs and are standard design practices for designers. Furthermore, an ultrasonic generator is installed between the side wall of the ultrasonic cleaning tank 43 and the housing 41; this ultrasonic generator is also a standard design practice. The sea sand screened from the bottom plate 21 enters the ultrasonic cleaning tank 43. When the ultrasonic generator is activated, in conjunction with the positive electrode 42 and negative electrode 44, the electrolytic reaction and the ultrasonic stripping effect work synergistically to efficiently remove harmful impurities from the surface of the sea sand. Specifically, the positive electrode 42 loses electrons and undergoes oxidation. In the reaction, metallic iron dissolves into ferrous ions, which enter the electrolyte and decompose metal oxides or impurities such as rust and heavy metal compounds on the surface of the sea sand. Cations such as metal ions in the electrolyte gain electrons at the negative electrode 44 and undergo a reduction reaction, producing hydrogen bubbles. In addition, ultrasonic waves generate tiny bubbles in the electrolyte, which form shock waves when they collapse, peeling off tiny particles on the surface of the sea sand. High-frequency vibrations promote the electrolyte to penetrate the gaps in the sea sand, accelerating the removal of impurities such as biofilm, salt, and organic matter. Then, the sand enters the auger component 46, which is driven by the start of the drive motor 45 to transport the sea sand towards the discharge port 47 and discharge it from the inner cavity of the discharge port 47 into the inner cavity of the feed port 53.

[0022] The nano-oxidation reaction mechanism 5 includes a collection box 51. A feed inlet 53 is located on the upper right side of the collection box 51. A nano-gaseous oxidant generator 54 is fixedly connected to the upper left side of the collection box 51. A tube 591 is fixedly connected to the inner cavity of the collection box 51. A second feed inlet 56 is located on the upper side of the outer surface of the tube 591, and the inner cavity of the second feed inlet 56 communicates with the inner cavity of the first feed inlet 53. A second drive motor 52 is fixedly connected to the right end of the tube 591, and an auger is rotatably connected to the inner cavity of the tube 591. Roller 57, the output end of drive motor 2 52 is fixedly connected to the right end of auger roller 57, a number of heating wires 58 in a ring array are provided between the outer surface of tube body 591 and inner cavity, a water filter screen 59 is provided on the lower left side of inner cavity of tube body 591, a filter group 55 is fixedly connected to the lower left side of collection box 51, the right end of collection box 51 is fixedly connected to the lower left side of steel frame 1, the lower end of discharge port 47 is fixedly connected to the upper right side of collection box 51, and the inner cavity of discharge port 47 is connected to the inner cavity of inlet 1 53.

[0023] The detailed installation methods, circuit connections, and control methods for the drive motor 52, nano-gaseous oxidant generator 54, and heating wire 58 are all conventional designs, representing standard design practices. The diameter of the filter screen 59 is smaller than that of the sea sand. The nano-gaseous oxidant generated by the nano-gaseous oxidant generator 54, such as nano-ozone and nano-chlorine dioxide, effectively removes trace pollutants, soluble salts, and microorganisms remaining in the sea sand through efficient penetration and oxidation reactions. The processed sea sand then enters the inner cavity of the pipe body 591 through the inner cavity of the second inlet 56. Then, the second drive motor 52 and the heating wire 58 are started. The second drive motor 52 drives the auger roller 57 to rotate, and the sea sand is transported by the auger roller 57. During the transportation process, the sea sand is heated by the heating wire 58. The water in the sea sand is filtered through the water filter screen 59 and enters the inner cavity of the collection box 51. The sea sand is then transported to the left while being heated until it is discharged from the left outlet of the pipe body 591. The filtered water is then pumped into the filter group 55.

[0024] Example 2: Please see Figure 7-8 This utility model provides a technical solution: a modular sea sand rapid desalination device, the filter group 55 includes a tank 551, an inlet pipe 552 is fixedly connected to the upper end of the tank 551, an outlet pipe 553 is fixedly connected to the lower end of the tank 551, a coarse filter plate 557 and a multi-media filter 556 are fixedly connected in sequence to the upper side of the inner cavity of the tank 551, a sodium ion exchange column 555 and an activated carbon filter cartridge 554 are fixedly connected in sequence to the middle of the inner cavity of the tank 551, the end of the outlet pipe 553 away from the tank 551 is fixedly connected to the return water pipe 3, and the end of the inlet pipe 552 away from the tank 551 is fixedly connected to the lower front end of the collection box 51.

[0025] Based on Example 1, the method is further improved by drawing water from the collection tank 51 into the upper part of the inner cavity of the tank 551 through the inlet pipe 552. Then, the water passes through the coarse filter plate 557 to remove visible or larger suspended impurities in the dewatered water. The multi-media filter 556 further removes fine suspended particles, colloidal substances, and some turbidity from the water, making the water quality clear. Next, the sodium ion exchange column 555 removes hardness ions such as calcium and magnesium from the water to prevent scaling of the equipment. Finally, the activated carbon filter cartridge 554 adsorbs trace pollutants and odors, ensuring that the water quality in the final outlet pipe 553 and return pipe 3 is free of odors and harmful pollutants when recycled to the ultrasonic cleaning tank 43, thus avoiding secondary impact on the sea sand desalination effect or the equipment.
