Description

A solid-liquid separation water treatment device with fluorescence detection Technical Field

[0001] The invention relates to the technical field of water treatment equipment, in particular to a solid-liquid separation water treatment device with fluorescence detection. Background Art

[0002] Water is an inorganic substance composed of two elements, hydrogen and oxygen. It is a colorless, odorless, transparent liquid at normal temperature and pressure. Water is one of the most common substances. It is an important resource for the survival of all life, including humans. It is also the most important component of organisms. Water has played an important role in the evolution of life. In recent years, water pollution caused by industrial wastewater has been serious, especially the problem of heavy metal ion pollution in water bodies. Heavy metal ions such as copper, cadmium, mercury, and lead in wastewater seriously endanger human health. At present, in order to make the water treatment effect reach the normal drinking water drinking standard, the content of heavy metals in the water needs to be reduced before water supply.

[0003] A Chinese patent discloses an energy-saving wastewater treatment equipment containing heavy metal ions (authorization announcement number CN211226506U). Its specification discloses that "after the wastewater reacts, some sediment will be produced. The mud pump is controlled to work so that the mud pump can extract the sediment from the bottom of the box, and the sediment can be effectively discharged." However, during the extraction process of the above-mentioned sediment, due to the lack of corresponding interception measures around the clear liquid, as the sediment in the box continues to decrease, the remaining clear liquid in the box is in a flowing state, which means that part of the clear liquid will also be discharged, resulting in less than ideal solid-liquid separation effect.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. After the heavy metals in the box are precipitated, the clear liquid in the box can be continuously precipitated through the filter membrane by means of filter press. At this time, the clear liquid can be continuously extracted through the water suction disc, so that the solid and liquid in the box are separated, which improves the solid-liquid separation effect. Compared with the traditional method of extracting sediment from the bottom, this method will not cause large-scale diffusion of sediment in the box, which can greatly reduce water pollution and improve the cleanliness of water resources after extraction.

[0017] 2. By installing corresponding ultraviolet lamps around the test box, the water source in the test box can be sterilized by ultraviolet light to reduce the growth of bacteria in the water. In addition, the ultraviolet lamp that can be adjusted up and down can also be used to conduct all-round testing of the water source in the test box. When the test box contains heavy metal ions, the heavy metal ions have a quenching effect on the fluorescent material in the test box, and the test box will not show a fluorescent effect at this time. When there are no heavy metal ions in the test box, it means that the test box does not contain heavy metal ions. Therefore, the water source in the liquid storage tank after the liquid is extracted can be tested for heavy metal content. When the test result does not meet the standard, the water source is re-injected into the box for re-precipitation, so that the heavy metal content of the water source in the liquid storage tank reaches the actual drinking standard.

[0029] The detection mechanism 6 includes a detection box 61, a second servo motor 62 and a protective frame 63. The second servo motor 62 is fixed to the top center of the detection box 61. The driving end of the second servo motor 62 is fixed to a driving gear 621. The front and rear sides of the driving gear 621 are meshed with driven gears 622. The top of the detection box 61 is also fixed to a protective frame 63 covering the driving gear 621 and the driven gear 622. The first pad 64 and the second pad 66 are fixed to the front, rear, left and right sides of the detection box 61. 5. The bottom of the driven gear 622 is fixed with a screw rod 66. The external thread of the screw rod 66 is provided with an adjustment frame 67. The internal movement of the adjustment frame 67 is penetrated by eight guide rods 68. Eight ultraviolet lamps 69 are fixed to the inner wall of the adjustment frame 67. The guide rods 68 are fixed between the first pad 64 and the second pad 65. The adjustment frame 67 is a "Hu" shaped structure, and the adjustment frame 67 is movably sleeved at the periphery of the detection box 61. The driven gear 622 and the screw rod 66 are aligned with the central axis of the protective frame 63 as the reference. The detection box 61 is also fixedly connected to a first pipe, one end of the first pipe is fixedly connected to a second water pump, and the water inlet end of the second water pump is fixedly connected to a second pipe, and the second pipe is connected to the liquid storage barrel 59. By installing corresponding ultraviolet lamps 69 around the detection box 61, the water source in the detection box 61 can be sterilized by ultraviolet rays to reduce the growth of bacteria in the water. Moreover, the ultraviolet lamps 69 that can be adjusted up and down can also be used to perform all-round detection of the water source in the detection box 61. When the detection box 61 contains heavy metal ions, the heavy metal ions have a quenching effect on the fluorescent material in the detection box 61, and the detection box 61 will not have a fluorescent effect at this time. When there are no heavy metal ions in the detection box 61, it means that there are no heavy metal ions in the detection box 61, so that the water source in the liquid storage barrel 59 after the liquid is pumped can be tested for heavy metal content. When the test result does not meet the standard, the water source is re-injected into the box body 41 for re-precipitation, so that the heavy metal content of the water source in the liquid storage barrel 59 reaches the actual drinking standard.

[0030] Working principle: When using this device, pour water into the box 41, then pour an appropriate amount of heavy metal ion precipitation agent into the box 41, and start the motor 4. After the motor 4 is powered on, it drives the box 41 to rotate, and the water and the heavy metal ion precipitation agent can be evenly stirred. After the two react and stand for a period of time, some sediment will be generated in the box 41. Then control the first servo motor 511 to reverse, and at this time, the first rotating rod 512 and the second rotating rod 514 can be driven to reverse, and then the first winding drum 55 and the second winding drum 56 can be driven to reverse, so that the first safety rope 5 51 and the second safety rope 561 are in the line-releasing stage. Under the pulling force of the spring 581, the sealing ring 594 and the filter membrane 595 can be continuously moved downward. When the sealing ring 594 and the filter membrane 595 are continuously moved downward to the interior of the box body 41, the clear liquid is precipitated from the filter membrane 595. At the same time, the sealing ring 594 is pressed against the inner wall of the box body 41 to play a sealing role. At this time, by controlling the first water pump 591, the clear liquid can be sucked into the liquid storage barrel 59 through the water suction disc 593 and the hose 592, and the sediment is discharged through the sewage outlet on the front surface of the box body 41, and then the liquid storage barrel 59 is filled with water. The water source in the barrel 59 is pumped into the detection box 61 through the second water pump, and then the second servo motor 62 is controlled to work. After the second servo motor 62 is energized, it drives the driving gear 621 and the driven gear 622 to rotate, thereby driving the screw rod 66 to rotate continuously. Through the forward and reverse rotation of the screw rod 66, the adjustment frame 67 and the ultraviolet lamp 69 can be driven to move up and down. By installing corresponding ultraviolet lamps 69 around the detection box 61, the water source in the detection box 61 can be sterilized by ultraviolet light to reduce the growth of bacteria in the water. In addition, the ultraviolet lamp 69 that can be adjusted up and down can also be used to sterilize the detection box 67. The water source in the testing box 61 is tested in all directions. When the testing box 61 contains heavy metal ions, the heavy metal ions have a quenching effect on the fluorescent material in the testing box 61, and the testing box 61 will not have a fluorescent effect at this time. When there are no heavy metal ions in the testing box 61, it means that the testing box 61 does not contain heavy metal ions, so that the water source in the liquid storage barrel 59 after the liquid is extracted can be tested for heavy metal content. When the test result does not meet the standard, the water source is re-injected into the box body 41 for re-precipitation, so that the heavy metal content of the water source in the liquid storage barrel 59 reaches the actual drinking standard.

[0031] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
