Description

Technical Field

[0001] The utility model relates to the technical field of dredged fill tail water treatment, in particular to a dredged fill tail water treatment device. Background Technique

[0002] With the booming development of the coastal economy, port, waterway and dredged fill projects in China are being carried out on a large scale, and the construction scale is constantly expanding. Due to the high water content of the dredged soil, after being filled into the construction area, the water often drains out of the filled area through the ground drainage ditch and drainage outlet. At this time, some fine-grained sediment will be discharged from the filled area along with the water due to factors such as slow sedimentation speed and large water flow, and the turbid water body will cause certain pollution to the external ecological environment.

[0003] At present, the traditional dredged fill tail water treatment device still has the following problems: 1. Usually, the dredged fill tail water contains a large amount of suspended matter, sediment, organic matter and other pollutants. The existing dredged fill tail water treatment device cannot properly treat the dredged fill tail water and directly discharges it, which will cause serious pollution to the surrounding environment and affect the ecological balance and biodiversity; 2. When the existing dredged fill tail water treatment device works, impurities are easily adhered to the inner wall surface of the reaction tank, resulting in difficulty in cleaning the reaction tank. Therefore, we introduce a dredged fill tail water treatment device. Content of the Utility Model

The upper ends of the two connecting pipes are jointly fixedly connected with an installation frame. The upper part of the outer surface of the reaction tank is fixedly connected with a medicine inlet pipe in an inserted manner. The lower part of the outer surface of the reaction tank is fixedly connected with a water outlet pipe in an inserted manner. A control valve is inserted and movably installed on the outer surface of the water outlet pipe. Through holes are opened on the left and right lower inner wall surfaces of the installation frame. Two installation slots are opened on the front and rear inner wall surfaces of the installation frame. A filtering component is jointly clamped in the four installation slots. A stirring device is inserted and installed in the middle of the upper end of the reaction tank;

[0007] The stirring device includes a rotating motor. The output end of the rotating motor is fixedly installed with an installation rod. The upper, middle and lower outer surfaces of the installation rod are all fixedly connected with stirring rods. A number of through holes are opened on the outer surfaces of the three stirring rods. Scraper plates are fixedly connected to the ends of the three stirring rods far away from the center of the installation rod.

[0008] Preferably, the lower end of the rotary motor is fixedly connected to the upper end of the reaction tank, and the output end of the rotary motor penetrates through the upper end of the reaction tank and extends into the reaction tank.

[0009] By adopting the above technical solution: By fixedly connecting the lower end of the rotary motor to the upper end of the reaction tank, the stability of the rotary motor during operation is ensured, enabling it to continuously and smoothly drive the stirring device to operate without affecting the stirring effect and the normal operation of the equipment due to factors such as shaking.

[0010] Preferably, the lower end of the mounting rod is movably connected to the lower inner wall surface of the reaction tank through a bearing.

[0011] By adopting the above technical solution: This stable connection method helps to maintain the balance of the entire stirring device, avoiding the influence of the shaking or tilting of the mounting rod on the stirring effect and the stability of the equipment operation, thereby further improving the performance and reliability of the tail water treatment device.

[0012] Preferably, the three stirring rods are distributed in a circular array around the center of the mounting rod, and the outer surfaces of the three scraping plates are all in contact with the inner wall surface of the reaction tank.

[0013] By adopting the above technical solution: The outer surfaces of the three scraping plates are all in contact with the inner wall surface of the reaction tank, which can effectively prevent impurities in the tail water from depositing and adhering to the inner wall of the reaction tank, keep the inner wall of the reaction tank clean, and avoid affecting the equipment performance and subsequent treatment process due to the accumulation of impurities.

[0014] Preferably, the filtering component includes a fixed frame, two mounting clamping plates are fixedly connected to the front end and the rear end of the fixed frame respectively, and a filter net is embedded in the lower part of the inner wall surface of the fixed frame.

[0015] By adopting the above technical solution: The mounting clamping plates at the front end and the rear end enable the filtering component to be conveniently, quickly and firmly installed in the corresponding position, facilitating installation and disassembly, and being beneficial to the maintenance and replacement of the filter net.

[0016] Preferably, the fixed frame is movably sleeved in the mounting frame, and the four mounting clamping plates are respectively clamped in the corresponding four mounting slots.

[0017] By adopting the above technical solution: When the filter net needs to be replaced or maintained, the fixed frame can be taken out of the mounting frame through a simple operation, which is very convenient and reduces the maintenance difficulty and cost.

[0018] Compared with the prior art, the present utility model has the following beneficial effects:

[0019] 1. In the present utility model, the rotary motor provides power for stirring. Its fixed connection with the reaction tank ensures stability during operation. The mounting rod is movably connected to the lower inner wall surface of the reaction tank through a bearing, enabling the stirring action to be smooth and reducing frictional losses, thereby prolonging the service life of the equipment. The annular array distribution of the stirring rods can stir the tail water comprehensively and evenly, promoting the full mixing of the tail water and the reagent, accelerating the reaction speed, and improving the treatment effect. The water-permeable holes can reduce the stirring resistance and further enhance the uniformity of stirring. The scraper can prevent impurities from depositing on the tank wall, keeping the tank clean, and at the same time enhancing the disturbance of the tail water, improving the stirring effect and treatment quality.

[0020] 2. In the present utility model, the fixed frame and the mounting frame are connected by clamping the mounting clamping plate and the mounting clamping groove, making the installation and disassembly of the filter assembly convenient and fast, which is conducive to daily maintenance and replacement of the filter net. The filter net can effectively intercept larger impurities, preliminarily purify the tail water entering the reaction tank, reduce the subsequent treatment burden, and improve the overall treatment efficiency and effect.

[0029] Please refer to Figures 1-4 , the present utility model provides a technical solution:

[0030] A dredging and reclamation tail water treatment device includes a reaction tank 1. Both the left and right upper parts of the reaction tank 1 are fixedly connected with connecting pipes 2. The upper ends of the two connecting pipes 2 are jointly fixedly connected with an installation frame 3. The upper part of the outer surface of the reaction tank 1 is fixedly connected with a medicine inlet pipe 4 in an inserted manner. The lower part of the outer surface of the reaction tank 1 is fixedly connected with a water outlet pipe 5 in an inserted manner. A control valve 6 is movably installed on the outer surface of the water outlet pipe 5 in an inserted manner. Through holes 7 are opened on both the left and right lower inner wall surfaces of the installation frame 3. Two installation slots 8 are opened on both the front and rear inner wall surfaces of the installation frame 3. A filtering component 9 is jointly clamped in the four installation slots 8. A stirring device 10 is inserted and installed in the middle of the upper end of the reaction tank 1.

[0031] In this embodiment, the stirring device 10 includes a rotating motor 101. A mounting rod 102 is fixedly installed at the output end of the rotating motor 101. Stirring rods 103 are fixedly connected to the upper part, middle part, and lower part of the outer surface of the mounting rod 102. A number of water-permeable holes 104 penetrating through from front to back are formed on the outer surfaces of the three stirring rods 103. Scrapers 105 are fixedly connected to one ends of the three stirring rods 103 far away from the center of the mounting rod 102. The lower end of the rotating motor 101 is fixedly connected to the upper end of the reaction tank 1. The output end of the rotating motor 101 penetrates through the upper end of the reaction tank 1 and extends into the reaction tank 1. The lower end of the mounting rod 102 is movably connected to the lower inner wall surface of the reaction tank 1 through a bearing. The three stirring rods 103 are distributed in a circular array around the center of the mounting rod 102. The outer surfaces of the three scrapers 105 are in contact with the inner wall surface of the reaction tank 1.

[0032] Through the above solution: When the rotating motor 101 is started, the output end of the rotating motor 101 drives the mounting rod 102 to rotate in the reaction tank 1. The stirring rods 103 installed on the upper, middle, and lower parts of the outer surface of the mounting rod 102 rotate together with the mounting rod 102 to stir the tail water in the reaction tank 1. At the same time, the scrapers 105 at one ends of the three stirring rods 103 far away from the center of the mounting rod 102 will continuously scrape the inner wall of the reaction tank 1 when the stirring rods 103 rotate.

[0033] In this embodiment, the filtering assembly 9 includes a fixed frame 91. Two mounting clamping plates 92 are fixedly connected to the front end and the rear end of the fixed frame 91 respectively. A filter net 93 is embedded in the lower part of the inner wall surface of the fixed frame 91. The fixed frame 91 is movably sleeved in the mounting frame 3. The four mounting clamping plates 92 are respectively clamped in the corresponding four mounting slots 8.

[0034] Through the above solution: The fixed frame 91 is clamped in the mounting slots 8 in the mounting frame 3 through the mounting clamping plates 92 at its front end and rear end, so as to be stably installed in the mounting frame 3. When the tail water flows in the mounting frame 3, it will pass through the filter net 93 at the lower part of the inner wall surface of the fixed frame 91. When it is necessary to clean or replace the filter net 93, the fixed frame 91 can be conveniently disassembled from the mounting frame 3.

[0035] It should be noted that the present utility model is a dredging reclaimed water tail water treatment device. During use, the tail water is poured into the installation frame 3, and the filter component 9 in the installation frame 3 preliminarily filters the tail water to intercept larger impurity particles. The tail water after preliminary filtration enters the reaction tank 1 through the water outlet 7. At the same time, the treatment agent is injected into the reaction tank 1 through the medicine inlet pipe 4. The rotation motor 101 is started, and the rotation motor 101 drives the installation rod 102 to rotate, thereby causing the stirring rod 103 on the installation rod 102 to rotate. On the one hand, the stirring rod 103 makes the tail water and the treatment agent added from the medicine inlet pipe 4 fully mixed through stirring to accelerate the reaction. On the other hand, the water permeable holes 104 on the stirring rod 103 can reduce the resistance of water and improve the stirring efficiency. At the same time, the scraper 105 continuously scrapes the inner wall of the reaction tank 1 during rotation to prevent impurities from adhering to the tank wall. The water after reaction treatment precipitates under the action of gravity, and the clearer water accumulates at the lower part of the reaction tank 1. The control valve 6 is opened, and the treated water is discharged through the water outlet pipe 5. During the whole process, the filter component 9 can be regularly disassembled for cleaning or replacement to ensure its filtering effect, and the stirring device 10 continuously works to ensure sufficient reaction and the cleanliness inside the tank.
