Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment, in particular to laboratory organic wastewater degradation equipment. Background Art

[0002] The organic wastewater generated every day in the postgraduate entrance examination and testing laboratories of universities and research institutes needs to be regularly collected and centrally treated by full-time personnel and equipment. According to statistics, this type of wastewater is generally collected and treated once every two weeks or longer, but some of the high-risk organic wastewater needs to be treated as soon as possible to avoid harm during the accumulation and storage process.

[0003] After searching the Chinese patent with publication number CN118145851A, a laboratory wastewater treatment device and method are disclosed, wherein the laboratory wastewater treatment device includes a device body and universal wheels arranged at the four corners of the bottom of the device body, a wastewater treatment component arranged in the inner cavity of the device body for filtering wastewater, a cleaning component arranged on the wastewater treatment component, and a linkage component arranged on the cleaning component. The laboratory wastewater treatment device can perform primary filtration treatment on large impurity particles in the wastewater through the primary filter screen plate, reduce the load of subsequent treatment, and protect the normal operation of the device, and then effectively degrade organic waste in the wastewater by adding an oxidant to the wastewater, and convert the organic waste into inorganic products or substances that are easier to treat, thereby reducing the concentration of organic matter in the wastewater, reducing pollution to the environment, and making the wastewater easier to subsequently treat or discharge.

[0004] However, the prior art has the following disadvantages:

[0005] In the prior art, there is a method of treating the wastewater by mixing wastewater with ozone water and then catalyzing the wastewater with an ultraviolet light source. This method requires that the wastewater and ozone water be brought into contact with a nanofilter, with the nanofilter being a reaction substrate. However, when this technology is used, since the ultraviolet light source is disposed in the wastewater, certain substances in the wastewater are likely to remain on the surface of the ultraviolet light source after the reaction, affecting the irradiation of the ultraviolet light source on the wastewater and ozone water. Secondly, the mixing between ozone water and wastewater is likely to be uneven, which in turn leads to an insufficient reaction between the two, affecting the degradation effect.

[0018] The present invention provides a laboratory organic wastewater degradation device through improvement, which has the following improvements and advantages compared with the prior art:

[0019] First, the present invention sets a driving mechanism. When wastewater and ozone water are mixed inside the filter barrel, the driving motor can be started. The driving motor drives the first gear to rotate. The first gear and the transmission gear ring are meshed and transmitted, and then the nanochannel filter can be driven to rotate through the transmission gear ring. The rotation of the nanochannel filter can make the contact between the wastewater and the ozone water and the nanochannel filter more complete, thereby improving the reaction speed. The nanochannel filter drives the stirring blade to rotate. The rotation of the stirring blade can stir and mix the wastewater and the ozone water inside the treatment barrel. At the same time, the rotation of the transmission gear ring can drive the second gear to rotate, and the second gear drives the driving shaft to rotate. The driving shaft is threadedly connected to the transmission block. The rotation of the driving shaft will cause the transmission block to drive the movable sleeve to move back and forth on the ultraviolet light source. The movable sleeve moves back and forth on the ultraviolet light source to clean the surface of the ultraviolet light source, thereby avoiding the situation where impurities in the wastewater adhere to the ultraviolet light source and affect the illumination of the ultraviolet light source.

[0020] Secondly, the present invention arranges the flushing mechanism. When the movable sleeve moves downward, the movable sleeve will drive the piston rod to move, and the piston rod will then drive the piston block to move downward inside the piston tube. Under the action of suction, the waste water and ozone water in the middle position of the treatment barrel will be sucked into the interior of the piston tube through the water inlet hole. At the same time, through the arrangement of the water outlet hole, the waste water and ozone water at the bottom of the treatment barrel will also be sucked into the interior of the piston tube. However, since the inside of the water outlet hole gradually becomes smaller from the inside to the outside, the amount of waste water and ozone water entering the piston tube through the water outlet hole is much smaller than the amount entering through the water inlet hole. As the movable sleeve moves upward, the waste water and ozone water in the middle position of the treatment barrel will be sucked into the interior of the piston tube through the water inlet hole. As the piston moves, the piston block will also move upward inside the piston tube, thereby squeezing the wastewater and ozone water inside the piston tube. At this time, the wastewater and ozone water inside the piston tube will be discharged from the inside of the piston tube through the water outlet and the water inlet. Due to the shape of the water inlet and the water outlet, the amount of wastewater and ozone water discharged from the piston tube from the water outlet is greater than the amount discharged from the water inlet, so that the wastewater and ozone water above the filter barrel can be transferred to the lower part of the treatment barrel, thereby further improving the contact between the wastewater and ozone water and the nanochannel filter, improving the mixing effect of the wastewater and ozone water, and thereby enhancing the reaction effect.

[0021] Thirdly, the present invention arranges a sealing plate. When the wastewater in the filter barrel is sent into the treatment barrel through the wastewater supply pipe, the wastewater will squeeze the sealing plate, causing the sealing plate to move and leave the wastewater supply pipe. At this time, the wastewater can enter the treatment barrel. The sealing plate drives the sealing block to move inside the water inlet seat. At this time, the water inlet seat can be opened, and the ozone water in the ozone generator can enter the treatment barrel through the water inlet seat, thereby achieving the effect of automatically adding ozone water when discharging wastewater. At the same time, the mixing ratio between wastewater and ozone water can be adjusted.

[0022] Fourthly, in the present invention, after the waste water is discharged, the pressure-sensitive switch will start the electric control valve, and then clean water can be delivered to the interior of the filter barrel through the clean water inlet pipe, and the clean water enters the interior of the clean water delivery pipe. Since the clean water delivery pipe is located inside the sealing sleeve, under the action of pressure, the clean water delivery pipe will move downward, so that the water spray port on the clean water delivery pipe corresponds to the water spray port on the sealing sleeve. At this time, the clean water inside the clean water delivery pipe can be sprayed into the interior of the filter barrel through the water spray port, and the interior of the filter barrel can be cleaned at this time.

The stirring blades 24 are rectangular blocks, and the tops of the stirring blades 24 are inclined. Through the setting of the driving mechanism, when the wastewater and the ozone water are mixed inside the filter barrel 2, the driving motor 12 can be started, and the driving motor 12 drives the first gear 13 to rotate. The first gear 13 and the transmission gear ring 14 are meshed for transmission, and then the nanochannel filter 8 can be driven to rotate through the transmission gear ring 14. The rotation of the nanochannel filter 8 can make the wastewater and the ozone water contact with the nanochannel filter 8 more fully, thereby improving the reaction speed. The rice channel filter 8 drives the stirring blade 24 to rotate. The rotation of the stirring blade 24 can stir and mix the wastewater and ozone water inside the treatment barrel 3.

[0039] The flushing mechanism includes a piston tube 19, a piston block 20 and a piston rod 21. The piston tube 19 is a hollow cylindrical structure. The piston tube 19 is fixedly installed at the lower part of the processing barrel 3. The piston block 20 is a round block with the same size as the inside of the piston tube 19. The piston block 20 is movably installed at the upper part of the piston tube 19. The piston rod 21 is a "T"-shaped structure. The piston rod 21 is fixedly installed on the top of the piston block 20, and the piston rod 21 passes through the top wall of the piston tube 19.

A group of water outlet holes 23 are provided on the upper and lower sides of the side walls of the piston tube 19, which are circular holes that gradually become smaller from the inside to the outside. Through the arrangement of the flushing mechanism, when the movable sleeve 17 moves downward, the movable sleeve 17 will drive the piston rod 21 to move, and the piston rod 21 will then drive the piston block 20 to move downward inside the piston tube 19.

A movable rod 32 is fixedly installed on the sealing block 30. The movable rod 32 penetrates the side wall of the water inlet seat 28. The movable rod 32 is sleeved with a first spring 33. Through the setting of the sealing plate 31, when the wastewater inside the filter barrel 2 is sent into the interior of the treatment barrel 3 through the wastewater supply pipe 27, the wastewater will squeeze the sealing plate 31, so that the sealing plate 31 moves and leaves the interior of the wastewater supply pipe 27.

The rod 36 drives the mixing blade 35 to rotate, and the wastewater discharged from the wastewater supply pipe 27 will enter the interior of the mixing chamber 29 through the water inlet 34. At the same time, the ozone water inside the water inlet seat 28 will also enter the interior of the mixing chamber 29.

An electric push rod 40 is fixedly installed inside the adjusting groove 38. The output end of the electric push rod 40 is fixedly connected to the adjusting block 39. When the electric push rod 40 is started, the electric push rod 40 can drive the adjusting block 39 to move inside the adjusting groove 38, thereby adjusting the internal size of the sealing block 30, thereby changing the amount of ozone water entering the mixing chamber 29 through the sealing block 30, thereby adjusting the mixing ratio between the wastewater and the ozone water.

[0043] The filter barrel 2 is provided with a filter mechanism inside, and the filter mechanism includes a filter seat 41, a filter plate 42, a mounting block 43, a reset rod 44 and a second spring 45.

The reset rod 44 is fixedly mounted on the filter seat 41, and the reset rod 44 penetrates the upper and lower walls of the mounting block 43, and the second spring 45 is sleeved on the reset rod 44. When the wastewater impacts the filter plate 42, the filter plate 42 will drive the filter seat 41 to move downward, so that the reset rod 44 moves on the mounting block 43 and squeezes the second spring 45. When the filtration is completed, the second spring 45 will release the elastic force to drive the filter seat 41 and the filter plate 42 to reset, thereby making the filter plate 42 vibrate, shaking out the impurities blocked inside the filter plate 42, and avoiding the blockage of the filter plate 42;

[0044] A pressure plate 46 is movably installed at the lower part of the filter barrel 2. The pressure plate 46 is a circular plate with the same size as the inside of the filter barrel 2. A mounting spring rod 47 is fixedly installed inside the filter barrel 2. The mounting spring rod 47 penetrates the upper and lower walls of the pressure plate 46. The water pumping pipe 26 also penetrates the upper and lower walls of the pressure plate 46. A rectangular opening connected to the inside of the water pumping pipe 26 is opened below the side wall of the water pumping pipe 26. When the waste water is filtered, the pressure plate 46 is squeezed to make the pressure plate 46 move downward. When the pressure plate 46 moves to expose the opening below the water pumping pipe 26, the waste water can be sent into the inside of the treatment barrel 3 through the water pumping pipe 26. A clean water inlet pipe 48 is installed on the top of the filter barrel 2. The clean water inlet pipe 48 is connected to the inside of the filter barrel 2. The other end of the clean water inlet pipe 48 is connected to an external water source. An electric control valve 49 is installed on the clean water inlet pipe 48. A pressure switch 50 is installed at the lower part of the filter barrel 2. The pressure switch 50 is electrically connected to the electric control valve 49.

[0045] A sealing seat 51 is fixedly installed on the top of the filter barrel 2. The sealing seat 51 is a hollow cylindrical structure. The bottom of the clean water inlet pipe 48 is located inside the sealing seat 51. A clean water supply pipe 52 is movably installed below the inside of the sealing seat 51. The clean water supply pipe 52 is a cylindrical pipe. A sealing sleeve 54 is fixedly installed on the top wall inside the filter barrel 2. The sealing sleeve 54 is a cylindrical pipe. The clean water supply pipe 52 is located inside the sealing sleeve 54. The clean water supply pipe 52 and the sealing sleeve 54 both penetrate the upper and lower walls of the filter plate 42. A vortex blade 53 is movably installed inside the clean water supply pipe 52. A plurality of water spray ports 55 are provided on the clean water supply pipe 52 and the sealing sleeve 54. The positions of the water spray ports 55 on the clean water supply pipe 52 and the water spray ports 55 on the sealing sleeve 54 are staggered. A plurality of elastic members 56 are installed inside the sealing seat 51. The elastic members 56 is a hollow structure. When wastewater enters the filter barrel 2, the pressure plate 46 moves downward to trigger the pressure switch 50. When the wastewater is discharged, the pressure switch 50 starts the electric control valve 49, and then clean water can be delivered to the inside of the filter barrel 2 through the clean water inlet pipe 48. The clean water enters the inside of the clean water supply pipe 52. Since the clean water supply pipe 52 is located inside the sealing sleeve 54, under the action of pressure, the clean water supply pipe 52 will move downward, so that the water spray port 55 on the clean water supply pipe 52 corresponds to the water spray port 55 on the sealing sleeve 54. At this time, the clean water in the clean water supply pipe 52 can be sprayed into the inside of the filter barrel 2 through the water spray port 55. At this time, the inside of the filter barrel 2 can be cleaned. When it is not cleaned, the sealing sleeve 54 can seal the clean water supply pipe 52 to prevent wastewater from entering the inside of the clean water supply pipe 52.

[0046] Specific implementation steps: When the wastewater and ozone water enter the interior of the treatment barrel 3 together, the wastewater and ozone water are mixed, and the ultraviolet light source 9 is started. Under the irradiation of the ultraviolet light source 9, the wastewater and ozone water flow through the surface of the nanochannel filter 8, and the harmful molecules in the wastewater are degraded into CO 2 , H 2 O or other low-risk small molecules, when the wastewater is treated, it can be discharged from the filter barrel 2 through the drain pipe 10;

[0047] By setting the driving mechanism, when the wastewater and the ozone water are mixed inside the filter barrel 2, the driving motor 12 can be started, and the driving motor 12 drives the first gear 13 to rotate. The first gear 13 and the transmission gear ring 14 are meshed and transmitted, and then the nanochannel filter 8 can be driven to rotate through the transmission gear ring 14. The rotation of the nanochannel filter 8 can make the wastewater and the ozone water contact with the nanochannel filter 8 more fully, thereby improving the reaction speed. The nanochannel filter 8 drives the stirring blade 24 to rotate, and the rotation of the stirring blade 24 can rotate the treatment barrel 3. The wastewater and ozone water inside are stirred and mixed, and at the same time, the rotation of the transmission gear ring 14 can drive the second gear 15 to rotate, and the second gear 15 drives the driving shaft 16 to rotate, and the driving shaft 16 is threadedly connected with the transmission block 18. The rotation of the driving shaft 16 will cause the transmission block 18 to drive the movable sleeve 17 to move back and forth on the ultraviolet light source 9. The movable sleeve 17 moves back and forth on the ultraviolet light source 9 to clean the surface of the ultraviolet light source 9, thereby preventing impurities in the wastewater from adhering to the ultraviolet light source 9 and affecting the illumination of the ultraviolet light source 9.

[0048] At the same time, through the setting of the flushing mechanism, when the movable sleeve 17 moves downward, the movable sleeve 17 will drive the piston rod 21 to move, and the piston rod 21 will then drive the piston block 20 to move downward inside the piston tube 19. Under the action of suction, the waste water and ozone water in the middle position of the treatment barrel 3 will be sucked into the interior of the piston tube 19 through the water inlet hole 22. At the same time, through the setting of the water outlet hole 23, the waste water and ozone water at the bottom of the treatment barrel 3 will also be sucked into the interior of the piston tube 19. However, since the inside of the water outlet hole 23 gradually becomes smaller from the inside to the outside, the amount of waste water and ozone water entering the piston tube 19 through the water outlet hole 23 is much smaller than the amount entering through the water inlet hole 22. As the movable sleeve 17 moves upward, the waste water and ozone water in the middle position of the treatment barrel 3 will be sucked into the interior of the piston tube 19 through the water inlet hole 22. As the piston block 20 moves, it will also move upward inside the piston tube 19, thereby squeezing the wastewater and ozone water inside the piston tube 19. At this time, the wastewater and ozone water inside the piston tube 19 will be discharged from the inside of the piston tube 19 through the water outlet hole 23 and the water inlet hole 22. Due to the shape of the water inlet hole 22 and the water outlet hole 23, the amount of wastewater and ozone water discharged from the piston tube 19 from the water outlet hole 23 is greater than the amount discharged from the water inlet hole 22, so that the wastewater and ozone water above the inside of the filter barrel 2 can be transferred to the inside of the treatment barrel 3. The contact between the wastewater and ozone water and the nanochannel filter 8 is further improved, the mixing effect of the wastewater and ozone water is improved, and the reaction effect is enhanced.
