Description

Technical Field

[0001] This utility model relates to the field of organic solvent wastewater treatment technology, and in particular to an organic solvent wastewater treatment device. Background Technology

[0002] Organic solvent wastewater refers to wastewater containing organic matter, such as wastewater discharged from pharmaceutical factories, which may contain drug residues, organic solvents, organic acids, and other organic substances. These organic substances pose a certain pollution risk to the environment and therefore require treatment. Wastewater treatment first requires filtration to remove larger particles of impurities from the organic solvent wastewater. These impurities will settle to the bottom of the treatment tank. When a significant amount of impurities settles at the bottom, the drain valve on the drain pipe at the bottom of the tank must be opened to discharge the impurities from inside the tank. Once all the impurities have been discharged, the drain valve should be closed. A drawback is that if the drain valve is not closed promptly after all the impurities have been discharged, the wastewater inside the tank will be discharged through the drain pipe, affecting wastewater treatment. Utility Model Content

[0003] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose an organic solvent wastewater treatment device to solve the technical problem that, in the existing organic solvent wastewater treatment devices, if the drain valve is not closed in time after all impurities have been discharged from the treatment tank, the wastewater inside the treatment tank will be discharged through the drain pipe, affecting the wastewater treatment.

[0004] To achieve the above-mentioned technical objectives, the present invention provides an organic solvent wastewater treatment device, including a treatment tank. Inside the treatment tank is a filter plate that divides the left and right sides of the treatment tank into a filtration zone and a water storage zone. Inside the filtration zone is a partition that divides the upper and lower sides of the filtration zone into a wastewater zone and an impurity zone. The partition has a through hole, and a drain pipe is located at the bottom of the impurity zone. The treatment device also includes a control valve mechanism, which includes a first sealing plug located above the through hole and a second sealing plug located below the drain pipe. The first and second sealing plugs are connected by a linkage rod. The control valve mechanism also includes a drive device for driving the second sealing plug to rise and fall.

[0005] Furthermore, the bottom of the second sealing plug is connected to the drive unit via an elastic component.

[0006] Furthermore, the elastic component includes a connecting rod installed at the bottom of the second sealing plug, a limit block installed at the lower end of the connecting rod, an annular connecting plate sleeved on the connecting rod, the top of the annular connecting plate being connected to the bottom of the second sealing plug via a first spring, the bottom of the annular connecting plate being connected to the top of the limit block via a second spring, a connecting block being provided on the outer wall of the annular connecting plate, and the connecting block being connected to the driving device.

[0007] Furthermore, an observation window is provided on the side wall of the impurity area.

[0008] Furthermore, the partition has a funnel-shaped structure.

[0009] Furthermore, the bottom of the impurity zone has a funnel-shaped structure.

[0010] Furthermore, both the first and second sealing plugs have a conical structure.

[0011] Furthermore, both the first and second sealing plugs have sealing layers on their sidewalls.

[0012] The beneficial effects of this utility model include: This utility model provides an organic solvent wastewater treatment device. When there are many impurities in the impurity zone, the second sealing plug is lowered by the drive device to open the drain pipe, so that the impurities inside the impurity zone can be discharged through the drain pipe. At the same time, the second sealing plug can drive the first sealing plug to lower through the linkage rod to close the through hole, so as to prevent the wastewater inside the wastewater zone from entering the impurity zone and being discharged through the drain pipe. This can prevent the wastewater from being discharged from the inside of the treatment tank during sewage discharge, thus avoiding affecting the wastewater treatment. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] This utility model provides an organic solvent wastewater treatment device, such as... Figs. 1-3As shown, the device includes a processing tank 1, inside which is a filter plate 2. The filter plate 2 divides the left and right sides of the processing tank 1 into a filtration zone 11 and a water storage zone 12. Inside the filtration zone 11 is a partition 3, which divides the upper and lower sides of the filtration zone 11 into a wastewater zone 13 and an impurity zone 14. The partition 3 has a through hole 31. The bottom of the impurity zone 14 is provided with a drain pipe 4. The top of the wastewater zone 13 is provided with an inlet pipe 5. The bottom of the water storage zone 12 is provided with a drain pipe 6. The processing device also includes a control valve mechanism 7. The control valve mechanism 7 includes a first sealing plug 71 located above the through hole 31 and a second sealing plug 72 located below the drain pipe 4. The first sealing plug 71 and the second sealing plug 72 are connected by a linkage rod 73. The control valve mechanism 7 also includes a drive device 74. The drive device 74 is one of a cylinder, a hydraulic cylinder, or an electric telescopic rod. The drive device 74 is used to drive the second sealing plug 72 to rise and fall. When treating organic solvent wastewater, the wastewater enters the wastewater zone 13 through the inlet pipe 5. It is filtered by the filter plate 11 and then enters the storage zone 12 and is discharged through the drain pipe 6. The wastewater then enters the next stage of treatment equipment. Meanwhile, larger particles in the organic solvent wastewater settle into the impurity zone 14. When there are many impurities in the impurity zone 14, the second sealing plug 72 is lowered by the drive device 74, opening the drain pipe 4 and allowing the impurities in the impurity zone 14 to be discharged through the drain pipe 4. At the same time, the second sealing plug 72 can drive the first sealing plug 71 to lower through the linkage rod 73, closing the through hole 31. This prevents the wastewater in the wastewater zone 13 from entering the impurity zone 14 and being discharged through the drain pipe 4, thus preventing the wastewater from being discharged from the treatment tank 1 during sewage discharge and avoiding any impact on wastewater treatment.

[0019] It should be noted that the baffle 3 has a funnel-shaped structure, which allows impurities at the bottom of the wastewater zone 13 to automatically flow into the impurity zone 14, preventing impurities from remaining at the bottom of the wastewater zone 13; the bottom of the impurity zone 14 has a funnel-shaped structure, which allows impurities inside the impurity zone 14 to automatically flow into the sewage pipe 4 and be discharged through the sewage pipe 4, preventing impurities from remaining at the bottom of the impurity zone 14.

[0020] It should be noted that both the first sealing plug 71 and the second sealing plug 72 are conical structures, which can improve the sealing effect on the through hole 31 and the drain pipe 4 respectively. At the same time, the side walls of the first sealing plug 71 and the second sealing plug 72 are provided with sealing layers, which are either silicone or rubber layers, and can further improve the sealing effect on the through hole 31 and the drain pipe 4.

[0021] In this embodiment, the bottom of the second sealing plug 72 is connected to the driving device 74 via an elastic component 75. The elastic component 75 applies an elastic thrust when the first sealing plug 71 and the second sealing plug 72 seal the through hole 31 and the drain pipe 4, thereby improving the sealing effect of the first sealing plug 71 and the second sealing plug 72 on the through hole 31 and the drain pipe 4. More specifically, the elastic component 75 includes a connecting rod 751 installed at the bottom of the second sealing plug 72, a limit block 752 installed at the lower end of the connecting rod 751, and an annular connecting plate 753 sleeved on the connecting rod 75. The top of the annular connecting plate 753 is connected via a first elastic component 751. Spring 754 is connected to the bottom of the second sealing plug 72. The bottom of the annular connecting plate 753 is connected to the top of the limiting block 752 via the second spring 755. The outer wall of the annular connecting plate 753 is provided with a connecting block 756, which is connected to the driving device 74. When the first sealing plug 71 seals the through hole 31, the first spring 754 is stretched, and the second spring 755 is compressed, applying an elastic thrust to the first sealing plug 71. When the second sealing plug 72 seals the drain pipe 41, the first spring 754 is compressed, and the second spring 755 is stretched, applying an elastic thrust to the second sealing plug 72.

[0022] In this embodiment, an observation window 9 is provided on the side wall of the impurity area 14. Through the observation window 9, the staff can easily observe the amount of impurities inside the impurity area 14, so that the staff can control the discharge of impurities according to the amount of impurities inside the impurity area 14.

[0023] Specific principle: When treating organic solvent wastewater, the wastewater enters the wastewater zone 13 through the inlet pipe 5. It is filtered by the filter plate 2, and the filtered wastewater enters the storage zone 12 and is discharged through the drain pipe 6, then proceeds to the next stage of treatment. Simultaneously, larger particles in the wastewater settle into the impurity zone 14. When there are many impurities in the impurity zone 14, the drive device 74 controls the second sealing plug 72 to descend, opening the drain pipe 4 and allowing the impurities in the impurity zone 14 to be discharged through the drain pipe 4. At the same time, the second sealing plug 72 can drive the first sealing plug through the linkage rod 73. The plug 71 descends, closing the through hole 31 to prevent wastewater from entering the impurity zone 14 and being discharged through the drain pipe 4. This avoids wastewater being discharged from the treatment tank 1 during sewage discharge, thus preventing any impact on wastewater treatment. After all impurities have been discharged from the impurity zone 14, the second sealing plug 72 is raised by the drive device 74 to close the drain pipe 4. At the same time, the second sealing plug 72 can drive the first sealing plug 71 to rise via the linkage rod 73, opening the through hole 31 so that wastewater from the wastewater zone 13 can enter the impurity zone 14 and allow the impurities in the wastewater to settle into the impurity zone 14.

[0024] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
