Description

Technical Field

[0001] The utility model relates to the technical field of seawater desalination treatment, in particular to a seawater desalination preliminary treatment device. Background Art

[0002] Desalination is the production of fresh water by desalination of seawater. It is an open-source incremental technology for realizing the utilization of water resources. It can increase the total amount of fresh water and is not affected by time, space and climate. It can ensure a stable water supply for drinking water for coastal residents and water replenishment for industrial boilers. The process of obtaining fresh water from seawater is called desalination. The desalination methods currently used include seawater freezing, electrodialysis, distillation, reverse osmosis, and ammonium carbonate ion exchange. At present, the application of reverse osmosis membrane and distillation is the mainstream in the market. However, the content of sediment in seawater is relatively high. When initially treating seawater, employees need to frequently add reagents to the sedimentation tank, which is easy to increase the workload of employees. In addition, it is difficult to centrally treat the precipitated impurities, which causes secondary pollution of seawater and seriously affects the efficiency of initial desalination treatment. Utility Model Content

[0003] The technical problem to be solved by the utility model is that the content of sediment in seawater is relatively high. When initially treating the seawater, employees are required to frequently add reagents to the sedimentation tank, which easily increases the workload of employees, and the precipitated impurities are difficult to be centrally treated, thereby causing secondary pollution of the seawater and seriously affecting the efficiency of the initial treatment of seawater desalination.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A seawater desalination preliminary treatment device comprises a mixing box, wherein a double-shaft motor is fixedly connected to the center of the top of the mixing box, a rotating block is rotatably connected to the output end above the double-shaft motor, a convex block is fixedly connected to one side of the upper surface of the rotating block, a stirring rod which penetrates the mixing box and extends to the inside thereof is fixedly connected to the output end below the double-shaft motor, a medicine box is fixedly connected to the top of the mixing box through a fixed column, a medicine leakage pipe is fixedly connected to the bottom of the medicine box, the top of the medicine leakage pipe is communicated with the inside of the medicine box, the bottom of the medicine leakage pipe is communicated with the inside of the mixing box, a fixed column is fixedly connected to one side of the medicine leakage pipe, a baffle with an L-shaped cross section is rotatably connected to the outer surface of the fixed column, a concave hole matching with the baffle is provided at the position of the medicine leakage pipe, a spring is fixedly connected to one end of the baffle away from the concave hole, and the other end of the spring is fixedly connected to the medicine delivery pipe, a water inlet is fixedly provided on one side of the upper end of the mixing box, a filter box is provided at one end of the mixing box away from the water inlet and is communicated with the filter box through a pipe, a reverse osmosis tank is provided on the other side of the filter box and is communicated with the reverse osmosis tank through a pipe, and a water outlet is provided on the other side of the reverse osmosis tank.

[0006] Furthermore, a support platform is fixedly connected to the bottom of the mixing box, and the filter box and the reverse osmosis tank are both located on the support platform.

[0007] Furthermore, a sedimentation box is provided on the support platform below the mixing box, a mud pump is fixedly connected to one side of the sedimentation box, and a cleaning vehicle is provided below the mud outlet of the mud pump.

[0008] Working principle and beneficial effects:

[0009] When using the device, first pour the medicine into the medicine box, start the double-axis motor, and the output end above the double-axis motor rotates to drive the rotating block to rotate. When the convex block above the rotating block squeezes the baffle, the baffle uses the fixed column as a fulcrum to make the baffle located inside the medicine leakage pipe slide outward, and the medicine flows into the mixing box through the gap of the medicine leakage pipe. When the convex block does not squeeze the baffle, the spring rebounds, so that the baffle inside the medicine leakage pipe blocks the medicine from falling into the mixing box; at the same time, the output end below the double-axis motor drives the stirring rod to rotate, so that the medicine and the sediment fully react and precipitate. After precipitation, the sediment gathers in the sedimentation box, and the sediment is pumped into the cleaning vehicle by the mud pump.

[0010] The utility model allows the medicine to fall into the mixing box by squeezing the convex block on the rotating block with the baffle plate. When the convex block does not squeeze the baffle plate, the spring rebounds, so that the baffle plate inside the medicine leakage pipe blocks the medicine from falling into the mixing box. The device can automatically add the medicine into the mixing box, reduce the repetitive work of employees, and save labor costs. Moreover, the precipitated silt can be pumped into the cleaning vehicle through the sludge pump, so that the silt can be centrally processed, avoiding secondary pollution to the seawater in the subsequent steps.
