Description

Technical Field

[0001] The utility model belongs to the technical field of wastewater treatment, and in particular relates to a zero-discharge treatment device for cyanide-containing wastewater. Background Art

[0002] Cyanide-containing wastewater is usually produced in pharmaceutical, pesticide, gold extraction, gold tailings, and electroplating wastewater. It is highly toxic and has a great impact on the environment. Therefore, it needs to be treated to meet the emission standard of less than 0.5 mg / L.

[0003] The existing method for treating cyanide-containing wastewater is chemical oxidation, which involves adding sodium hypochlorite to the cyanide-containing wastewater under alkaline conditions to break the cyanide. After the cyanide-containing wastewater meets the standards, it is directly discharged. However, the sodium hypochlorite added to the wastewater will cause insufficient mixing and reaction, resulting in waste and affecting the working progress of the device. Therefore, we need to upgrade and transform it based on the existing technology. Utility Model Content

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figure 1 - Figure 5 As shown, the present embodiment provides a zero-discharge treatment device for cyanide-containing wastewater, comprising a device body 1, the device body 1 containing a wastewater tank 2, a cover plate 4 provided on the wastewater tank 2 and a discharge pipe 11 provided below the wastewater tank 2, a dosing port 7 and a motor 8 provided on the cover plate 4, a connecting rod 9 connected below the motor 8, a stirring blade 10 sleeved on the connecting rod 9, a connecting pipe 13 connected to the discharge pipe 11 and a control valve 12 provided on the discharge pipe 11, one end of the connecting pipe 13 is connected to the filter box 14, a limit clamp 15 is installed on the outer wall of the filter box 14, a plug-in rod 16 is inserted in the limit clamp 15, a filter screen 17 is installed below the plug-in rod 16, one end of the filter box 14 is connected to a connecting pipe 21, one end of the connecting pipe 21 is connected to a collecting box 23 and a control valve 22 is installed on the connecting pipe 21, one end of the collecting box 23 is provided with an outlet pipe 24, and the outlet pipe 24 is provided with a control valve 3 25.

[0025] Preferably, support legs 3 are installed on the outer wall of the wastewater tank 2, and two groups of support legs 3 are symmetrically arranged. The support legs 3 are fixedly connected to the wastewater tank 2. By setting the support legs 3, the stability of the wastewater tank 2 is increased, and the safety of the wastewater tank 2 during use is guaranteed. There are multiple groups of stirring blades 10, and the stirring blades 10 are fixedly connected to the connecting rod 9. By setting the stirring blades 10, the medicine and wastewater entering the wastewater tank 2 can be evenly mixed and stirred, thereby accelerating the dissolution rate of the medicine. Extension buckles 5 are installed on the cover plate 4 and the outer wall of the wastewater tank 2, and bolts 6 are screwed in the extension buckles 5. By setting the bolts 6, the cover plate 4 and the wastewater tank 2 can be connected and fixed, thereby ensuring the safety of the device during use.

[0026] Preferably, a handle 18 is installed above the plug-in rod 16, and the handle 18 is fixedly connected to the plug-in rod 16. By providing the handle 18, it is convenient for the user to pull out and take the device, which provides convenience for the user. A pin hole 19 is provided in the limit clamp 15, and a square pin 20 is inserted into the pin hole 19. By providing the square pin 20, the device can be limited and fixed, ensuring the safety of the device when in use.

[0027] The use principle and use process of the present invention are as follows: when in use, the user puts the medicine used for wastewater treatment into the wastewater tank 2 through the medicine adding port 7. After the addition is completed, the user controls the motor 8 to run, and the motor 8 drives the connecting rod 9 to rotate. When the connecting rod 9 rotates, it drives the stirring blade 10 to mix and stir the medicine and the wastewater. During the stirring process, the medicine and the wastewater react. After the wastewater treatment is completed, the user opens the control valve 12, and the treated wastewater enters the connecting pipe 13 through the discharge pipe 11, and then enters the filter box 14 through the connecting pipe 13. The wastewater entering the filter box 14 is filtered by the filter screen 17. After the filtration is completed, the control valve 22 is opened, and the filtered water enters the collection box 23 through the connecting pipe 21 for collection, which can evenly mix the cyanide-containing wastewater and the wastewater treatment medicine. The filter 17 can be removed from the filter box 14 by pulling the handle 18 upwards, which speeds up the dissolution rate of the medicine and makes it easier for users to filter and collect the wastewater, thereby increasing the practicality and convenience of the device. When it is necessary to disassemble the filter 17 of the device, the user manually removes the square latch 20 from the latch hole 19 of the limit clamp 15 in sequence. After removal, the user pulls the handle 18 upwards, and the handle 18 moves upwards, driving the connecting rod 16 to move upwards in the limit clamp 15, and at the same time drives the filter 17 to move upwards in the filter box 14 until the connecting rod 16 is completely separated from the limit clamp 15, thereby realizing the removal of the filter 17. Conversely, the device can be installed, and the filter 17 of the device can be installed and fixed according to the needs of the user, which is convenient for the user to disassemble and replace the filter 17 later, avoiding the trouble of inconvenient maintenance and cleaning of the device.
