Description

Technical Field

[0001] The invention relates to the field of wastewater treatment equipment, and more specifically to a suction filtration type fluorine-containing wastewater treatment device. Background Art

[0002] Wastewater refers to the general term for water discharged during residents' activities and runoff rainwater. It includes domestic sewage, industrial wastewater, and other unused water such as initial rain runoff into drainage pipes. Wastewater discharged by industries such as electroplating, fertilizers, coking, and pesticides contains high concentrations of fluoride. Fluoride is one of the essential trace elements for the human body, but excessive fluoride intake will lead to fluoride poisoning. Therefore, the high concentration of fluoride contained in wastewater not only seriously pollutes the environment, but also seriously endangers people's physical and mental health. It is necessary to use wastewater treatment equipment to purify fluoride-containing wastewater.

[0003] The existing fluorine-containing wastewater treatment device is composed of a stirring mechanism, a dosing mechanism, a filtering mechanism, etc. When in use, the fluorine-containing wastewater is introduced into the stirring mechanism, and then the reagent is added into the stirring mechanism and stirred to promote the reaction of the reagent with the fluoride to form a precipitate, followed by static stratification, and then the sediment at the bottom is artificially discharged into the filtering mechanism for dehydration, so as to achieve the purpose of removing fluoride in the wastewater. However, static stratification takes a long time, resulting in low treatment efficiency, and the filtering mechanism only uses suction filtration for dehydration, and the dehydration effect is poor. At the same time, as the thickness of the filter cake increases, the filtration resistance gradually increases, and the filtration efficiency gradually decreases, resulting in a further decrease in the treatment efficiency. Therefore, it is urgent to design a suction filtration type fluorine-containing wastewater treatment device. Summary of the invention

[0018] 3. Beneficial effects

[0019] Compared with the prior art, the advantages of the present invention are:

[0020] 1. The treatment center can be controlled by the righting center so that the treatment center can inject wastewater into the separation component. No manual control is required, which saves time and effort and helps to increase the treatment efficiency. The wastewater can be filtered by the filter component to separate the solid and liquid. The negative pressure generator forms a vacuum state under the filter component to achieve the effect of suction filtration. The size of the filtration resistance can be monitored by the treatment center. When the filtration resistance is large, the separation component will replace the filter component to avoid the problem that as the thickness of the filter cake increases, the filtration resistance gradually increases and the filtration efficiency gradually decreases, resulting in a further decrease in the treatment efficiency. This helps to further increase the treatment efficiency. By controlling the filtration resistance, the filter cake has good water permeability to ensure that the wastewater can quickly pass through the filter cake. There is no need to statically stratify the wastewater, which saves time and helps to increase the treatment efficiency again, thereby improving the practicality of the suction filtration type fluorine-containing wastewater treatment device.

[0021] 2. A vacuum state is formed under the filter component through a negative pressure generator to achieve the effect of suction filtration. The lifting component can move upward with the extrusion structure, and the extrusion structure can move the filter component upward with the filter component. The filter cake is pushed upward by the filter component that moves upward, and the pressure cover structure enables the filter component to clamp the filter cake to achieve the effect of pressure filtration. The combination of suction filtration and pressure filtration can increase the dehydration effect. The filter cake can be automatically removed through the pressure cover structure, and there is no need to remove the filter cake manually, which saves time and effort. The filter component can be backflushed through the backflushing mechanism to open the blocked pores on the filter component to achieve the effect of plugging, thereby improving the practicality of the suction filtration type fluorine-containing wastewater treatment device.

[0046] Working principle:

[0047] First, the intelligent control component 33 controls the power motor 401 to run at a constant power, and then the power motor 401 rotates the power disc 404 through the power long shaft 405, and then the power disc 404 drives the negative pressure connecting rod 411 to reciprocate in the radial direction through the plug-in effect between the negative pressure pin 412 and the centrifugal ring groove 407. In the process that the negative pressure connecting rod 411 drives the negative pressure piston 410 to move radially away from the power disc 404, the negative pressure piston 410 squeezes the cavity inside the negative pressure generating chamber 408, and then the medium inside the negative pressure generating chamber 408 is discharged from the discharge check valve 413. In the process that the negative pressure connecting rod 411 drives the negative pressure piston 410 to move radially toward the power disc 404, the air pressure inside the negative pressure generating chamber 408 is reduced. The medium in the separation chamber 27 below the filter assembly 5 is driven by the pressure difference and enters the negative pressure generating chamber 408 through the negative pressure suction pipe 28, the fixed through hole 417, the arc-shaped buffer chamber 414, the delivery one-way valve 415, and the Z-shaped tube 416. The above is repeated to achieve the purpose of discharging the medium in the separation chamber 27 below the filter assembly 5. Then the air pressure in the cavity below the filter assembly 5 in the separation chamber 27 is reduced. Then a pressure difference is formed on the upper and lower sides of the filter assembly 5 to provide power for the filtration. Then the wastewater reacts with the agent under the action of stirring to form particles. Then the wastewater enters the first separation chamber 27 through the water inlet elbow 12 at a constant flow rate under the action of the water pump. Then the wastewater passes through the pressure difference. The pores and liquid leakage holes 56 on the water filter cloth 53 fall inside the tapered grooves 83 and the cylindrical grooves 84, and the particles in the wastewater are retained on the surface of the water filter cloth 53 and form a filter cake. Then the wastewater fills the tapered grooves 83 and the cylindrical grooves 84 and overflows from the top of the recoil disc 82. Then the overflowed wastewater falls on the bottom surface of the inner cavity of the separation chamber 27 and is discharged through the negative pressure suction pipe 28. Then, as the working time is extended, the filter cake on the top surface of the water filter cloth 53 becomes thicker and thicker, the resistance of the wastewater passing through the filter cake becomes greater and greater, and the water permeability efficiency of the filter cake gradually decreases. Then the liquid level of the wastewater above the water filter cloth 53 gradually increases, and then the ultrasonic liquid level sensor 15 constantly monitors the liquid level height and sends the data to the intelligent control component 33. When the data value is the same as the preset value inside the intelligent control component 33, the intelligent control component 33 controls the solenoid valve 13 to close and stop the injection of wastewater. Then the intelligent control component 33 controls the driving servo motor 25 to run, and then the driving servo motor 25 drives the transmission tube 23 to rotate clockwise through the meshing action between the driving bevel gear 26 and the driven bevel gear 24. Then the transmission tube 23 drives the separation column 22 to rotate clockwise, and then the separation column 22 drives the filter component 5, the extrusion structure 6, and the support arm 73 to rotate. Then the first negative pressure suction pipe 28 is staggered with the fixed through hole 417. Then the residual wastewater above the filter component 5 passes through the filter component 5 under the action of the residual pressure difference to achieve filtration, and then the first separation chamber 27 moves to the bottom of the special-shaped pressure plate 92.Then, the driving gear 75 rotates with the winding wheel 76 through the linkage short shaft 74 under the action of meshing between it and the notched tooth ring 72. Then, the lifting wire 77 is wound around the outside of the winding wheel 76 and pulls the extrusion cylinder 61 upward through the lifting arm 78. The extrusion cylinder 61 squeezes and stretches the spring 65 to increase its elastic potential energy. Then, the extrusion cylinder 61 moves upward with the extrusion rod 64 through the adaptation spring 62 and the extrusion piston 63. Then, the extrusion rod 64 moves upward with the filter assembly 5. Then, the filter assembly 5 presses the filter cake on its top surface onto the bottom surface of the special-shaped pressure plate 92. Then, the residual wastewater in the filter cake passes through the filter assembly 5 under the action of squeezing, achieving the effect of filter pressing. Then, the separation column 22 rotates ninety degrees, and then the intelligent control component 33 controls the drive servo The motor 25 stops running. At this time, the second negative pressure suction pipe 28 is connected to the fixed through hole 417, so that the corresponding second filter component 5 is located below the water inlet elbow 12. Then the intelligent control component 33 controls the solenoid valve 13 to open, and then the wastewater falls from the water inlet elbow 12 onto the top surface of the second filter component 5. The second filter component 5 filters the wastewater. After that, the liquid level on the top surface of the second filter component 5 reaches the preset value inside the intelligent control component 33. Then the intelligent control component 33 controls the driving servo motor 25 to run, so that the separation column 22 rotates ninety degrees. Then the driving gear 75 corresponding to the first separation chamber 27 continues to roll on the notched tooth ring 72, so that the extrusion cylinder 61 moves upward. At this time, the extrusion rod 64 is restricted by the filter cake and cannot move upward. Then the extrusion cylinder 61 squeezes The adapter spring 62 is elastically compressed, and the elastic potential energy increases, and then the first separation chamber 27 moves out from under the special-shaped pressure plate 92, and then the extrusion piston 63 moves upward with the extrusion rod 64 under the action of the elastic force of the adapter spring 62, and then the extrusion rod 64 moves upward with the filter assembly 5, and then the filter assembly 5 pushes the filter cake upward from the first separation chamber 27 until the limit ring 66 contacts the bottom surface of the recoil disc 82, at this time, the top surface of the water filter cloth 53 and the installation pressure ring 54 is flush with the top surface of the separation column 22, and then the separation column 22 rotates ninety degrees to end, at this time the third negative pressure suction pipe 28 is connected to the fixed through hole 417, the third filter assembly 5 is aligned with the water inlet elbow 12, and then the liquid level on the third filter assembly 5 reaches the intelligent control The preset value inside the component 33 is then controlled by the intelligent control component 33 to rotate the separation column 22 by ninety degrees, and then the filter cake on the top surface of the first filter component 5 rotates relative to the transition arc plate 94 and the gradual centrifugal arc plate 95, and then the filter cake contacts the gradual centrifugal arc plate 95, and then the gradual centrifugal arc plate 95 applies a centrifugal thrust to the filter cake to make the filter cake move centrifugally, and then the filter cake slides down from the top surface of the water filter cloth 53, the separation column 22, and the separation cylinder 21 and falls on the top surface of the guide inclined plate 16, and then the filter cake slides downward along the top surface of the guide inclined plate 16 and is discharged from the falling inclined pipe 17, and then the separation column 22 rotates ninety degrees to end, at this time the fourth negative pressure suction pipe 28 is connected to the fixed through hole 417, and in this process the driving gear 75 and the notch tooth ring 72 corresponding to the first separation chamber 27 are separated,The extrusion cylinder 61 moves downward relative to the extrusion piston 63 under the action of the elastic force of the adapting spring 62 until the extrusion piston 63 contacts the top surface of the inner cavity of the extrusion cylinder 61, and then the extrusion cylinder 61 moves downward with the first filter assembly 5 through the extrusion rod 64 under the action of the elastic force of the expansion spring 65, and then the bottom end of the protruding piston 55 is inserted into the tapered groove 83 and the cylindrical groove 84, and then the wastewater in the cylindrical groove 84 passes upward through the leakage hole 56 and the pores on the water filter cloth 53 under the action of the extrusion force, achieving the recoil effect, and then in the fourth When the liquid level on the top of the filter assembly 5 reaches the preset value inside the intelligent control component 33, the intelligent control component 33 controls the separation column 22 to rotate 90 degrees, and then the driving gear 75 corresponding to the first separation chamber 27 meshes with the notched tooth ring 72 again, and then the lifting component 7 drives the first filter assembly 5 to gradually move upward through the extrusion structure 6, and then the protruding piston 55 is pulled out from the tapered groove 83 and the cylindrical groove 84, and then when the separation column 22 stops rotating, the first separation chamber 27 moves to the bottom of the water inlet elbow 12, and the first separation chamber 27 is reset.
