TECHNICAL FIELD

[0001] The utility model relates to water treatment technical field especially relates to a rare earth oxide production water filtering recycling device. BACKGROUND

[0002] A large amount of wastewater is produced in the rare earth oxide production process, and the wastewater contains various harmful substances and impurities. If it is directly discharged, it will not only pollute the environment, but also waste valuable water resources. Therefore, filtering and recycling the rare earth oxide production water has important environmental protection significance and economic value.

[0003] When filtering these water, the filter screen aperture used in the traditional way is small, and the filtering effect is good. However, due to the fine mesh, the water body penetrates the filter screen at a low speed, which easily leads to the water body gathering above the filter screen and slowly penetrating, thereby resulting in low filtering efficiency. Therefore, how to increase the actual filtering speed is a problem we need to consider. UTILITY MODEL CONTENT

The device can accelerate the filtering operation and effectively improve the filtering efficiency. In addition, when the filter screen is blocked, the required downtime can be reduced.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

Detailed Implementation

[0021] Clearly, the described embodiments are merely part of the embodiments of the present application, rather than all the embodiments.

[0022] Referring to Figures 1-5 The rare earth oxide production water filtering and recycling device comprises a shell 1, a plurality of supporting legs are installed at the lower end of the shell 1, the shell 1 can be supported through the supporting legs, a negative pressure cavity 5 and a temporary storage cavity 6 are arranged in the shell 1, the negative pressure cavity 5 and the temporary storage cavity 6 are communicated through a first communication pipe 7, a second communication pipe 8 is formed in the inner bottom of the temporary storage cavity 6, an electromagnetic valve is installed in the first communication pipe 7 and the second communication pipe 8, in the initial state, the electromagnetic valve in the first communication pipe 7 is opened, and the electromagnetic valve in the second communication pipe 8 is closed, further, in order to ensure smooth drainage, the second communication pipe 8 can be designed to have a larger pipe diameter in actual design;

[0023] The filtering mechanism comprises two filter grooves 2 symmetrically formed in the top of the negative pressure cavity 5, a back-shaped mounting frame 10 is fixedly connected to the inner wall of each filter groove 2, and a filter screen 9 is installed on each back-shaped mounting frame 10; the mounting is achieved in the screw mounting mode, a negative pressure pump 4 is installed on the front side of the shell 1, and the air inlet end of the negative pressure pump 4 extends into the negative pressure cavity 5;

[0024] The adjustable sealing mechanism is used for sealing one of the filter grooves 2, and comprises a sliding groove 11 formed in the rear side wall of the negative pressure cavity 5, a threaded rod 12 rotatably connected between the left and right inner walls of the sliding groove 11, an L-shaped sliding strip 16 threadedly connected to the threaded rod 12, the L-shaped sliding strip 16 slidably connected to the inner wall of the sliding groove 11, a moving plate 13 fixedly connected to the other end of the L-shaped sliding strip 16, an installation groove formed in the upper end of the moving plate 13, a plurality of electric telescopic rods 15 installed in the inner bottom of the installation groove, further, a storage battery for supplying power to the electric telescopic rods 15 is installed in the moving plate 13, the control of the electric telescopic rods 15 is achieved in the wireless controller (i.e., the wireless module is integrated, which is convenient for actual operation, and a sealing door is installed on the rear side of the shell 1, which is convenient for charging the storage battery), the telescopic ends of the plurality of electric telescopic rods 15 are fixedly connected to a sealing plate 14, a rubber layer is further arranged on the upper side of the sealing plate 14, the actual sealing effect can be improved, a motor 3 is installed on the right side of the shell 1, the output shaft of the motor 3 extends into the sliding groove 11 and is fixedly connected to the right end of the threaded rod 12, and the motor 3 is a servo motor capable of changing the rotating direction.

[0025] In this utility model, during actual use, the water to be filtered is first filtered through the filter tank 2 on the right side. The water to be filtered is continuously poured into the filter tank 2 on the right side. As the water is continuously poured in, the mesh of the filter screen 9 is relatively fine, and water may accumulate on top of the filter screen 9. At this time, the negative pressure pump 4 can be started to reduce the air pressure inside the negative pressure chamber 5. Using the negative pressure difference, the water accumulated on top of the filter screen 9 can be quickly passed through the filter screen 9, thereby increasing the filtration speed. The water will enter the temporary storage chamber 6 through the first connecting pipe 7. When a lot of water accumulates in the temporary storage chamber 6, the solenoid valve in the first connecting pipe 7 can be closed, and then the solenoid valve in the second connecting pipe 8 can be opened to release the accumulated water. Then the solenoid valve in the second connecting pipe 8 can be closed, and then the solenoid valve in the first connecting pipe 7 can be opened.

[0026] When it is necessary to clean the right-side filter screen 9, simply start the multiple electric telescopic rods 15 to retract, then start the motor 3 to rotate forward, causing the threaded rod 12 to rotate, so that the L-shaped slide bar 16 drives the moving plate 13 to move to the right and below the right-side filter tank 2. Then start the multiple electric telescopic rods 15 to extend, causing the sealing plate 14 to move upward and seal the bottom of the right-side filter tank 2. The filtration operation can then continue through the left-side filter tank 2. At this time, another operator can disassemble the filter screen 9 and clean the right-side filter tank 2, thus reducing the overall downtime.

[0027] Similarly, the process is similar to the one described above when cleaning the filter 9 on the left side is required.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
