Description

Technical Field

[0001] This utility model relates to the field of silica precipitation equipment, and in particular to a precipitation device for silica processing. Background Technology

[0002] Silica, named for its similarity to carbon black and its white color, can be divided into precipitated silica (precipitated hydrated silica) and fumed silica (fumed silica) according to different production methods. Precipitation method production involves adding sulfuric acid to sodium silicate to precipitate silica.

[0003] The existing method for precipitating silica involves placing a mixed solution into a sedimentation tank for settling to allow solid-liquid separation, followed by liquid discharge to obtain precipitated silica. However, the closer the silica is to the bottom of the sedimentation tank, the higher the residual silica content in the liquid, and the more turbid the liquid becomes. Existing sedimentation devices cannot separate the liquid in the sedimentation tank for stratified discharge, and direct discharge of the liquid easily leads to waste of silica. Utility Model Content

[0004] (a) Technical problems to be solved To address the aforementioned problems in the prior art, this utility model provides a sedimentation device for silica processing, which can more conveniently and efficiently perform liquid stratification and discharge based on liquid turbidity. This allows the wastewater at the top of the sedimentation tank to be discharged, while the more turbid liquid on top of the sediment can be extracted for reuse, reducing the waste of silica.

[0005] (II) Technical Solution To achieve the above objectives, the main technical solutions adopted by this utility model include: A sedimentation device for processing silica includes a sedimentation tank, several liquid extraction components, a height adjustment mechanism, and a layer observation mechanism. The height adjustment mechanism is provided on one side of the sedimentation tank and is drivenly connected to the several liquid extraction components. One side of each of the several liquid extraction components is located inside the sedimentation tank, and the other side of each of the several liquid extraction components is located outside the sedimentation tank. The layer observation mechanism is provided on the other side of the sedimentation tank. The layered observation mechanism includes a transparent baffle, an illumination lamp, a mounting cover, and a vision sensor. A viewing window is provided on the other side of the sedimentation tank, and the transparent baffle is provided on the viewing window. The mounting cover is provided outside the transparent baffle, and the illumination lamp is provided inside the mounting cover. The illumination lamp illuminates the transparent baffle, and the vision sensor is also provided inside the mounting cover.

[0006] Furthermore, the height adjustment mechanism includes a slide bar, a screw jack, a lifting plate, and a connecting rod. A plurality of slide bars are provided on one side of the sedimentation tank. One side of the lifting plate is slidably connected to a plurality of slide bars. A plurality of connecting rods are provided on the other side of the lifting plate. A liquid extraction component is provided at the lower part of one of the connecting rods. The screw jack is drivenly connected to the lifting plate.

[0007] Furthermore, the liquid extraction assembly includes a fixed base, a liquid extraction pump, a liquid extraction pipe, and a liquid discharge pipe. The liquid extraction pump is connected to the connecting rod, and a liquid extraction pipe is provided at the lower part of the liquid extraction pump. One end of the liquid discharge pipe is connected to the upper part of the liquid extraction pump, and the other end of the liquid discharge pipe is connected to the outer surface of the sedimentation tank through the fixed base.

[0008] Furthermore, it also includes a discharge valve, wherein a discharge port is provided at the bottom of the sedimentation tank, and the discharge valve is provided inside the discharge port.

[0009] Furthermore, it also includes support feet, and several support feet are fixedly connected to the bottom of the sedimentation tank.

[0010] Furthermore, it also includes a PLC controller, which is electrically connected to the liquid extraction assembly, the height adjustment mechanism, and the layered observation mechanism, respectively.

[0011] (III) Beneficial Effects The beneficial effects of this invention are as follows: In actual production and use, when it is necessary to precipitate a solution of sodium silicate after adding sulfuric acid, the mixed solution can be placed in a sedimentation tank for settling. After a certain period of settling, the silica in the solution will precipitate to the bottom of the sedimentation tank. To better extract the liquid from the precipitate, an illumination lamp can be activated first, allowing the lamp to illuminate the inside of the sedimentation tank through a transparent baffle. Then, a vision sensor can be activated, allowing the sensor to observe the stratification of the sedimentation tank through the transparent baffle. Subsequently, based on the observed stratification, a height adjustment mechanism can be activated to adjust the sedimentation tank. The pumping assembly descends below the water surface, first extracting the water with the least turbidity from the top layer of the sedimentation tank and sending it to the wastewater treatment device for processing. Then, based on the stratification, the pumping assembly continues to descend to the height of the more turbid liquid, allowing it to be extracted and sent to the reuse filtration device for further fine filtration. Finally, the bottom layer of silica precipitate is obtained. This allows for more convenient and efficient stratification and discharge of liquids based on turbidity, enabling the discharge of the top layer of wastewater from the sedimentation tank and the extraction and reuse of the more turbid liquid above the precipitate, reducing the waste of silica.

Detailed Implementation

[0018] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] Please refer to Figures 1 to 5 As shown, a sedimentation device for processing silica according to this utility model includes a sedimentation tank 7, a plurality of liquid extraction components, a height adjustment mechanism, and a layer observation mechanism. The height adjustment mechanism is provided on one side of the sedimentation tank 7 and is drivenly connected to the plurality of liquid extraction components. One side of each of the plurality of liquid extraction components is located inside the sedimentation tank 7, and the other side of each of the plurality of liquid extraction components is located outside the sedimentation tank 7. The layer observation mechanism is provided on the other side of the sedimentation tank 7. The layered observation mechanism includes a transparent baffle 16, an illumination lamp 17, a mounting cover 10, and a vision sensor 9. A viewing window is provided on the other side of the sedimentation tank 7, and the transparent baffle 16 is provided on the viewing window. The mounting cover 10 covers the outside of the transparent baffle 16, and the illumination lamp 17 is provided inside the mounting cover 10. The illumination lamp 17 illuminates the transparent baffle 16, and the vision sensor 9 is also provided inside the mounting cover 10.

[0020] The working principle of this utility model is as follows: In actual production and use, when it is necessary to precipitate the solution after adding sulfuric acid to sodium silicate, the mixed solution can be placed in the sedimentation tank 7 for settling. After a certain period of settling, the silica in the solution precipitates to the bottom of the sedimentation tank 7. In order to better extract the liquid on the precipitate, the illumination lamp 17 can be turned on first, so that the illumination lamp 17 covers the inside of the sedimentation tank 7 through the transparent baffle 16. Then, the vision sensor 9 is turned on, so that the vision sensor 9 observes the stratification of the sedimentation tank 7 through the transparent baffle 16. Then, according to the observed stratification, the height adjustment mechanism is turned on, so that the height adjustment mechanism drives the liquid extraction component to descend below the water surface. The liquid extraction component first extracts the water with the least turbidity from the top layer of the sedimentation tank 7 to the wastewater treatment device for treatment. Then, according to the stratification, the liquid extraction component is lowered to the height of the more turbid liquid, so that the liquid extraction component extracts the more turbid liquid to the recycling filter device for further fine filtration. Finally, the bottom layer of white carbon black precipitate is obtained.

[0021] Furthermore, the height adjustment mechanism includes a slide bar 3, a screw jack 2, a lifting plate 1, and a connecting rod 4. A plurality of slide bars 3 are provided on one side of the sedimentation tank 7. One side of the lifting plate 1 is slidably connected to a plurality of slide bars 3. A plurality of connecting rods 4 are provided on the other side of the lifting plate 1. A liquid extraction component is provided at the lower part of one of the connecting rods 4. The screw jack 2 is drivenly connected to the lifting plate 1.

[0022] As can be seen from the above description, when it is necessary to extract the stratified liquid according to the stratification situation in the sedimentation tank 7, the screw jack 2 can be operated so that the screw jack 2 drives the connecting rod 4 through the lifting plate 1 to lift and lower the liquid extraction component to a suitable position for liquid extraction.

[0023] Furthermore, the liquid extraction assembly includes a fixed base 11, a liquid extraction pump 5, a liquid extraction pipe 6, and a liquid discharge pipe 12. The liquid extraction pump 5 is connected to the connecting rod 4. The liquid extraction pipe 6 is provided at the lower part of the liquid extraction pump 5. One end of the liquid discharge pipe 12 is connected to the upper part of the liquid extraction pump 5, and the other end of the liquid discharge pipe 12 is connected to the outer surface of the sedimentation tank 7 through the fixed base 11.

[0024] As can be seen from the above description, when liquid needs to be extracted, the height adjustment mechanism adjusts the height of the extraction pipe 6 through the extraction pump 5, so that the extraction pipe 6 extends into the liquid. Then, the extraction pump 5 is run, so that the liquid in the sedimentation tank 7 is discharged through the drain pipe 12. When the wastewater at the top of the sedimentation tank 7 is discharged, the drain pipe 12 is connected to the wastewater treatment device, so that the wastewater at the top layer is directly discharged into the wastewater treatment device for treatment. When a relatively turbid liquid is discharged, the drain pipe 12 can be connected to the reuse filter device, so that the liquid containing more silica can directly enter the reuse filter device for further filtration.

[0025] Furthermore, it also includes a discharge valve 15, and the lower part of the sedimentation tank 7 is provided with a discharge port 14, and the discharge valve 15 is provided inside the discharge port 14.

[0026] As can be seen from the above description, the silica that is conducive to the completion of precipitation is discharged outside the sedimentation tank 7 through the discharge port 14, and the discharge port 14 is opened and closed by the discharge valve 15.

[0027] Furthermore, it also includes support feet 8, and several support feet 8 are fixedly connected to the bottom of the sedimentation tank 7.

[0028] As can be seen from the above description, it is beneficial to make material discharge from outlet 14 more convenient and the device operation more stable.

[0029] Furthermore, it also includes a PLC controller, which is electrically connected to the liquid extraction assembly, the height adjustment mechanism, and the layered observation mechanism, respectively.

[0030] As can be seen from the above description, it is beneficial to adjust the parameters of the precipitation device for silica processing through the PLC controller, and to make it more convenient for operators to operate the precipitation device for silica processing. Example 1
