Description

Technical Field

[0001] The present application relates to the technical field of laboratory wastewater treatment, and in particular to an integrated chemical laboratory wastewater treatment device. Background Art

[0002] Chemical laboratory wastewater treatment is crucial, as it contains a variety of toxic, harmful, corrosive, flammable, and even carcinogenic substances and must never be discharged directly into sewers or the environment. Improper handling can seriously contaminate water sources and soil, damage ecosystems, endanger human health, and potentially violate strict environmental regulations. Chemical laboratory wastewater treatment is a systematic, professional, and strictly regulated process. The core is source reduction, strict classification and collection, and safe storage. Then, appropriate treatment methods are selected based on the properties of the wastewater, and harmless disposal is performed to meet discharge requirements before it can be discharged.

[0003] Chemical laboratory wastewater is usually discharged after being treated by a treatment device, such as a chemical laboratory wastewater treatment device with announcement number CN214528504U, which includes a box cover and a treatment device body, a rubber card slot is provided at the lower end of the box cover, a rubber card block that matches the rubber card slot is fixedly connected to the upper end of the treatment device body, a feed port is provided on one side of the upper end of the treatment device body, a drug inlet is provided on the other side of the upper end of the treatment device body, a rotating motor fixedly connected to the surface of the treatment device body is provided at the lower end of the feed port, the output end of the rotating motor is fixedly connected to a rotating shaft that passes through the interior of the treatment device body and is fixedly connected to the surface of the stirring blade, and a filter screen is provided at the lower end of the rotating shaft. The above-mentioned prior art can achieve a good stirring effect on wastewater, can also filter and purify wastewater, can also conveniently clean the interior of the wastewater treatment device, and can conveniently replace adsorption materials, which is relatively practical.

[0004] However, the above-mentioned existing technology still has some defects in the treatment of chemical laboratory wastewater: 1. When using the above-mentioned existing technology, the waste liquid and the degradation agent are poured into the feed port and the drug inlet respectively, and then the stirring blade is rotated to accelerate the mixing speed of the waste liquid and the degradation agent, so as to make the degradation more complete. However, since only one type of waste liquid can be treated at a time, chemical laboratories usually produce multiple waste liquids, and the efficiency of treating multiple waste liquids is low.

[0005] 2. When the degradation products need to be cleaned in the above-mentioned prior art, the filter screen is moved by pulling the handle, and then pulled out to clean the residue. The silica gel and activated carbon can be replaced, and the inside of the treatment device body can be cleaned by opening the box cover. However, when cleaning the inside of the treatment device body, it is not easy to clean the inside of the treatment device body thoroughly due to the obstruction of the rotating shaft and the stirring blades.

[0033] Example 1: refer to Figure 1 , an integrated chemical laboratory wastewater treatment device includes a treatment frame 11, a partition plate 12 is provided in the treatment frame 11, the partition plate 12 divides the treatment frame 11 into two areas, a treatment cover 13 is hinged on one side of the treatment frame 11, and when the treatment cover 13 is closed, a sealing area is formed on one side of the partition plate 12, and a snap 14 is provided on the upper end of the partition plate 12. When the treatment cover 13 is closed, the snap 14 locks the treatment cover 13, and a sealing strip 15 is provided at the lower end of the treatment cover 13. The sealing strip 15 is located at the connection between the treatment cover 13 and the treatment frame 11 to ensure the sealing inside the treatment frame 11, and a feeding frame 16 is provided on the upper end of the treatment cover 13. When treating wastewater, the wastewater is put into the treatment frame 11 through the feeding frame 16.

[0034] When treating wastewater, the treatment cover 13 covers the upper end of the treatment frame 11 and fixes it with the snap 14, so that a sealed area is formed on one side of the partition plate 12, and the area on the other side of the partition plate 12 is used to store drugs used to react with wastewater. The wastewater is then fed into the treatment frame 11 through the feeding frame 16 for harmless treatment.

[0035] refer to Figure 2 , is a structural schematic diagram of the mixing device 2 of the present invention. When different types of wastewater need to be treated, in order to use different types of reaction liquids to react with different types of wastewater respectively, a mixing device 2 is provided in the closed area below the partition plate 12. The mixing device 2 includes a driving motor 21 installed at the bottom end of the processing frame 11, a mounting frame 22 is provided at the lower end of the processing frame 11, a rotating disk 23 is provided at the upper end of the mounting frame 22, and the output end of the driving motor 21 is connected to the middle of the rotating disk 23. The driving motor 21 drives the rotating disk 23 to rotate. A plurality of mixing drums 24 are evenly installed circumferentially on the upper end of the rotating disk 23. When the rotating disk 23 rotates, the mixing drums 24 at the upper end of the rotating disk 23 are respectively located directly below the feeding frame 16 for respectively adding different types of wastewater and reaction liquid.

[0036] When treating different types of wastewater, the drive motor 21 is started to position the mixing drum 24 directly below the feed frame 16. At this time, wastewater and reaction liquid can be added from the feed frame 16 in sequence, and the wastewater and reaction liquid flow into the mixing drum 24. Then, the drive motor 21 is started again to position another mixing drum 24 directly below the feed frame 16. The above operation is repeated until different types of wastewater to be treated and the corresponding reaction liquid are respectively added to the mixing drum 24. The drive motor 21 drives the rotating disk 23 to rotate rapidly to allow the reaction liquid in the mixing drum 24 to fully react with the wastewater.

[0037] refer to Figure 3 , is a structural schematic diagram of the stirring device 3 of the present invention. In order to stir the reaction liquid and wastewater added to the mixing drum 24 and make them react quickly and fully, the mixing drum 24 is provided with a stirring device 3. The stirring device 3 includes a driving gear 31 installed on the output shaft of the driving motor 21. The driving motor 21 drives the driving gear 31 to rotate. A connecting gear ring 32 is provided at the lower end of the mounting frame 22. A rotating drum 33 is rotatably installed in the middle of the bottom end of the mixing drum 24, and the rotating drum 33 passes through the rotating drum 33 and the rotating disk 23. A connecting gear 34 is installed at the lower end of the rotating drum 33, and the connecting gear 34 is meshed with the driving gear 31 and the connecting gear ring 32 at the same time. Since the connecting gear 34 is meshed with the driving gear 31 and the connecting gear ring 32 at the same time, when the driving gear 31 rotates, the connecting gear 34 rotates around the driving gear 31 and rotates itself to drive the rotating drum 33 to rotate in the mixing drum 24. A connecting slide 35 is slidably installed inside the rotating drum 33. When the rotating drum 33 rotates, the connecting slide 35 rotates synchronously inside the rotating drum 33.

[0038] When the reaction liquid and wastewater added to the mixing drum 24 are stirred, the driving motor 21 drives the driving gear 31 to rotate. The connecting gear 34 is engaged with the driving gear 31 and the connecting gear ring 32. While the connecting gear 34 rotates around the driving gear 31, it also rotates itself to drive the rotating drum 33 and the connecting slide pipe 35 to rotate in the mixing drum 24.

[0039] refer to Figure 4, is a structural schematic diagram of the convection component 4 of the present invention. In order to make the wastewater and the reaction liquid convection in the mixing cylinder 24 to fully react and filter out the precipitate generated therefrom, the stirring device 3 also includes a convection component 4 arranged in the mixing cylinder 24. The convection component 4 includes an installation inner cylinder 41 arranged inside the mixing cylinder 24. The upper end of the installation inner cylinder 41 is provided with a fixing ring 42 that fits with the inner wall of the mixing cylinder 24. When mixing, the installation inner cylinder 41 is fixed in the mixing cylinder 24. The upper end of the side wall of the installation inner cylinder 41 is evenly provided with a plurality of connecting holes 43. The bottom of the installation inner cylinder 41 is evenly provided with a plurality of filtering holes 44. The filtering holes 44 filter the impurities generated by the reaction in the installation inner cylinder 41. Here, the convection component 4 also includes a stirring shaft 45 rotatably installed at the bottom end of the inner cylinder 41, and stirring blades 46 are evenly arranged on the side ends of the stirring shaft 45. When the stirring shaft 45 drives the stirring blades 46 to rotate, it drives the liquid in the inner cylinder 41 to flow downward, pass through the filter hole 44, and flow upward from the outside of the inner cylinder 41, and then enter the inner cylinder 41 again through the connecting hole 43 to realize circular convection. A connecting groove 47 is provided at the lower end of the stirring shaft 45, and a connecting protrusion 48 is provided at the upper end of the connecting slide 35 to match the connecting groove 47. The connecting groove 47 is engaged with the connecting protrusion 48. When the connecting slide 35 rotates in the mixing cylinder 24, the stirring shaft 45 is driven to rotate.

[0040] When the wastewater and reaction liquid in the mixing cylinder 24 are stirred and mixed, the installation inner cylinder 41 is placed in the mixing cylinder 24 so that the connecting groove 47 and the connecting protrusion 48 are engaged. The connecting slide 35 rotates to drive the stirring shaft 45 to rotate, so that the stirring blade 46 stirs the liquid in the installation inner cylinder 41, so that the liquid in the installation inner cylinder 41 flows downward, passes through the filter hole 44, flows upward from the outside of the installation inner cylinder 41, and then enters the installation inner cylinder 41 again through the connecting hole 43, realizing circular convection. At the same time, the impurities generated by the reaction of the wastewater and the reaction liquid are filtered by the filter hole 44 and stay at the bottom of the installation inner cylinder 41. When cleaning it, open the processing cover 13, take out the installation inner cylinder 41 and it can be processed.

[0041] refer to Figure 5, is a structural schematic diagram of the collecting device 5 of the present invention. In order to collect and discharge the gas generated during the reaction and collect the harmless wastewater after the reaction, a collecting device 5 is provided at the lower end of the rotating disk 23. The collecting device 5 includes a collecting frame 51 arranged at the lower end of the processing frame 11. The treated wastewater in the mixing drum 24 enters the collecting frame 51 through the connecting slide 35. A rotating ring 52 is rotatably installed on the upper end of the collecting frame 51, and the lower end of the rotating drum 33 is installed on the rotating ring 52 to prevent the wastewater from leaking from the upper end of the collecting frame 51. A connecting spring 53 is provided between the lower end of the connecting slide 35 and the rotating drum 33. A plurality of liquid outlet holes 54 are opened at the side end of the connecting slide 35. The connecting spring 53 causes the connecting slide 35 to be located at the upper end of the rotating drum 33, thereby helping the wastewater in the mixing drum 24 to enter the connecting slide 35 through the liquid outlet holes 54 and flow into the collecting frame 51.

[0042] When the wastewater and the reaction liquid react, the connecting slide 35 is pressed down by installing the inner cylinder 41, so that the liquid outlet 54 is located in the rotating cylinder 33. At this time, the liquid in the mixing cylinder 24 cannot flow out from the liquid outlet 54. After the reaction is completed, under the action of the connecting spring 53, the connecting slide 35 and the installing inner cylinder 41 move upward, so that the liquid outlet 54 is located above the connecting slide 35. At this time, the liquid in the mixing cylinder 24 enters the connecting slide 35 from the liquid outlet 54 and flows into the collection frame 51.

[0043] refer to Figure 6 In order to control the discharge and collection of the gas in the mixing cylinder 24, a drain pipe 55 is provided at the side end of the collection frame 51, and the drain pipe 55 passes through the side wall of the collection frame 51. The drain pipe 55 is used to discharge the waste liquid in the collection frame 51. The drain pipe 55 is connected in series with a first control valve 56. The first control valve 56 controls the drain pipe 55 to discharge the waste liquid in the collection frame 51. The upper and lower ends of the side wall of the processing frame 11 are jointly installed with a connecting pipe 57, and the connecting pipe 57 is passed into the interior of the processing frame 11. The middle part of the side end of the connecting pipe 57 is connected to an exhaust pipe. Tube 58, a second control valve 59 is symmetrically provided on the side end of the connecting pipe 57, and the second control valve 59 is respectively located above and below the exhaust pipe 58. When the density of the gas generated by the reaction is large, the second control valve 59 above the exhaust pipe 58 is closed, and the second control valve 59 below the exhaust pipe 58 is used to control the gas in the mixing drum 24 to enter the exhaust pipe 58 from the lower end of the connecting pipe 57 for discharge and collection. Similarly, if the density of the gas generated by the reaction is small, the second control valve 59 above the exhaust pipe 58 is used to control the gas to be discharged and collected.

[0044] Example 2: refer to Figure 7On the basis of Example 1, in order to control the wastewater and reaction liquid to enter the mixing drum 24, and at the same time control the wastewater and reaction liquid to be collected through the collection frame 51 after the reaction, a pressing device 6 is provided on the processing cover 13, and the pressing device 6 includes a sliding rod 61 slidably arranged in the middle of the processing cover 13, and an adjusting ring 62 is rotatably installed on the upper end of the processing cover 13, and the adjusting ring 62 is connected to the sliding rod 61 through a thread. The adjusting ring 62 is rotated, and the sliding rod 61 is slid up and down under the thread cooperation of the adjusting ring 62 and the sliding rod 61. The lower end of the sliding rod 61 is rotatably installed with a pressing top cover 63, and the sliding rod is slid downward. 61, the installation inner cylinder 41 and the connecting slide pipe 35 are pressed down by pressing down the top cover 63, thereby preventing the waste water from being discharged through the liquid outlet 54, and a plurality of positioning protrusions 64 corresponding to the installation inner cylinder 41 are evenly arranged on the circumference of the lower end of the pressing top cover 63. The positioning protrusions 64 cover the upper end opening of the installation inner cylinder 41 to prevent the waste water from splashing out, and a guide hole 65 is provided in the middle of the positioning protrusion 64, and the guide hole 65 passes through the positioning protrusion 64 and the pressing down top cover 63, and a guide cover 66 is provided on the upper end of the guide hole 65. The waste water and reaction liquid input from the feed frame 16 enter the mixing cylinder 24 through the guide cover 66 and the guide hole 65.

[0045] Before adding wastewater and reaction liquid, cover the processing cover 13 on the processing frame 11 and fix it with the buckle 14, then rotate the adjusting ring 62 to slide the sliding rod 61 downward, and then move the downward pressing top cover 63 downward, and the positioning protrusion 64 covers the upper end opening of the installation inner cylinder 41, and continue to move the downward pressing top cover 63 downward to press the installation inner cylinder 41 and the connecting slide pipe 35 downward, so that the liquid outlet 54 is located in the rotating cylinder 33. At this time, the wastewater and reaction liquid can be added to the feed frame 16 and enter the mixing cylinder 24 through the guide cover 66 and the guide hole 65.

[0046] refer to Figure 8 , is a schematic diagram of the structure of the barrier assembly 7 of the present invention. In order to prevent wastewater from being added into the mixing drum 24 when the liquid outlet 54 is at the upper end of the rotating drum 33, so that the wastewater leaks directly from the liquid outlet 54, a barrier assembly 7 is provided at the bottom of the feed frame 16. The barrier assembly 7 includes a guide pipe 71 provided at the lower end of the feed frame 16, and a barrier plug 72 is slidably provided in the guide pipe 71. When the barrier plug 72 is located at the upper end of the guide pipe 71, it will block the guide pipe 71 to prevent the wastewater in the feed frame 16 from flowing into the mixing drum 24. In the closing cylinder 24, a push rod 74 is installed in the guide hole 65 through the connecting frame 73, and the push rod 74 is located directly below the blocking plug 72. When the sliding rod 61 is located at the upper end of the processing cover 13, the push rod 74 pushes the blocking plug 72 upward, so that the blocking plug 72 remains in a state of blocking the guide tube 71. Then, when the sliding rod 61 slides downward, the push rod 74 moves downward accordingly, and the blocking plug 72 moves downward under the action of gravity, so that the wastewater in the feed frame 16 flows downward through the guide tube 71.

[0047] When the processing cover 13 is covered, the sliding rod 61 is located at the upper end of the processing cover 13. At this time, the top rod 74 pushes the blocking plug 72 from the lower end of the guide tube 71, pressing the top cover 63 down to fix it while pushing the blocking plug 72 upward, so that the blocking plug 72 keeps blocking the guide tube 71. At this time, the wastewater added to the feed frame 16 will not flow out through the guide tube 71. Then, when the sliding rod 61 slides downward, the connecting slide tube 35 is pressed down by installing the inner cylinder 41, so that the liquid outlet 54 is located in the rotating cylinder 33, and the top rod 74 moves downward accordingly. The blocking plug 72 moves downward under the action of gravity, so that the wastewater in the feed frame 16 flows downward through the guide tube 71 to the mixing cylinder 24.

[0048] refer to Figure 9 , is a structural schematic diagram of the liquid storage device 8. In order to store the reaction liquid, a liquid storage device 8 is provided in the processing frame 11.

The plastic hose 83 is provided with a liquid outlet head 84 at one end away from the drainage pipe 82. The reaction liquid in the liquid storage pipe passes through the drainage pipe 82 and the plastic hose 83 in turn and flows out through the liquid outlet head 84. After the wastewater is put into the mixing drum 24 through the feed frame 16, the liquid outlet head 84 is controlled to be connected to the guide pipe 71, so that the reaction liquid enters the mixing drum 24 through the guide pipe 71.
