Description

Technical Field

[0001] The utility model relates to the technical field of diamond micropowder production, in particular to a diamond micropowder wastewater residual material classification precipitation recovery system. Background Art

[0002] The production process of diamond micropowder generates a large amount of wastewater. The graded finished products must also be washed before drying. The wastewater generated during the production process will carry away a portion of very small particles, accounting for about 0.5%-1% of the total. The wastewater is generally discharged into a large sedimentation tank, and the deposited materials in the sedimentation tank are regularly removed. However, due to the long sedimentation time in the sedimentation tank, the different types of materials and waste liquids contained in the sedimentation tank, and the high impurity content, the subsequent treatment of the extracted materials is more difficult, increasing the treatment cost. If the wastewater is discharged directly into the sewage treatment plant, the materials in the wastewater will be lost and wasted.

[0003] Chinese patent publication number CN11425979A discloses a diamond micropowder wastewater recycling system. The recycling system utilizes a filter plate, cam, drive motor, drive rod, reset assembly, and a receiving box to coordinate with each other. Wastewater is pumped into a recycling box for processing. The cam and reset assembly drive the filter plate to vibrate, filtering the wastewater through the vibration of the filter plate. After filtration, the powder mixed in the wastewater is collected in the receiving box, thereby avoiding the loss of the powder and causing material waste. However, treating wastewater in this way requires the addition of a treatment fluid, making subsequent processing of the recovered sample more cumbersome. Furthermore, the treatment effect is poorer when treating wastewater containing finer micropowders, resulting in higher processing costs, a more complex subsequent processing process, and complex equipment with a low degree of automation.

[0004] The existing diamond micropowder wastewater residual material classification sedimentation recovery system has a poor collection effect on the diamond micropowder in the wastewater during use, which easily causes material waste, and the sedimentation recovery efficiency is low, which increases time costs.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

The utility model can facilitate multi-stage sedimentation of wastewater through the coordinated use of the primary sedimentation tank, the first and second sedimentation tanks, the second and second sedimentation tanks and the tertiary sedimentation tank, thereby improving the collection efficiency and collection effect of diamond micropowder in the wastewater.

After the treatment is completed, the lifting pump and the first electromagnetic valve extract the wastewater inside the primary sedimentation tank, and then transport it to the first and second sedimentation tanks and the second and second sedimentation tanks through the second electromagnetic valve. The first and second sedimentation tanks and the second and second sedimentation tanks perform secondary sedimentation on the wastewater.

[0021] See also Figure 1-Figure 3 A diamond micro powder wastewater residual material graded sedimentation recovery system includes a primary sedimentation tank 1, a first and second sedimentation tank 2, a second and second sedimentation tank 3 and a tertiary sedimentation tank 4.

[0022] Furthermore, the top of the first-level sedimentation tank 1 is connected to a first solenoid valve 7, the liquid outlet end of the first solenoid valve 7 is connected to a lifting pump 8, the liquid outlet end of the lifting pump 8 is connected to a second solenoid valve 9, the second solenoid valve 9 is connected to the first and second-level sedimentation tanks 2 and the second-level sedimentation tank 3 respectively, the top of the first and second-level sedimentation tanks 2 and the second-level sedimentation tank 3 is connected to a third solenoid valve 10, the liquid outlet end of the third solenoid valve 10 is connected to a flow pump 11, the liquid outlet end of the flow pump 11 is connected to a fourth solenoid valve 12, the liquid outlet end of the fourth solenoid valve 12 is connected to the top of the tertiary sedimentation tank 4, and the liquid outlet end of the tertiary sedimentation tank 4 is connected to a fifth solenoid valve 13.

[0023] Furthermore, a liquid inlet is installed on the top of the primary sedimentation tank 1. By setting the liquid inlet, wastewater can be easily injected into the primary sedimentation tank 1.

[0024] Furthermore, water level detectors 5 are installed on the tops of the primary sedimentation tank 1 , the first and second sedimentation tanks 2 , the second and second sedimentation tanks 3 and the tertiary sedimentation tank 4 .

[0025] By providing the water level detector 5 , it is possible to conveniently detect the liquid levels inside the primary sedimentation tank 1 , the first and second sedimentation tanks 2 , the second and second sedimentation tanks 3 and the tertiary sedimentation tank 4 .

[0026] Working principle: Set the corresponding sedimentation time for wastewater containing different materials, and then start the PLC control system. The system detects the water level in the first sedimentation tank. If it detects that the water level is higher than the minimum water level line, it starts the timing function. After the timing ends, it starts the lifting pump 8 and the first solenoid valve 7 to pump the waste liquid from the first sedimentation tank 1 to the second sedimentation tanks 2 and 3. The water level detectors in the second sedimentation tanks 2 and 3 are used to determine whether a sedimentation process is in progress. If the water level in the first and second sedimentation tanks 2 is at the lowest water level, the solution in the first sedimentation tank 1 is pumped to the first and second sedimentation tanks 2. If the water level in the first and second sedimentation tanks 2 is higher than the lowest water level, it is determined whether the water level in the second and second sedimentation tanks 3 is at the lowest water level. If so, the solution in the first sedimentation tank 1 is pumped to the second and second sedimentation tanks 3. If the water level in the second and second sedimentation tanks 3 is higher than the lowest water level, the solution is pumped to the first and second sedimentation tanks 2. The timing of the second sedimentation tanks 2 and 3 starts again. After the sedimentation of the second sedimentation tanks 2 and 3 is completed, the system starts the third solenoid valve 10 after the corresponding sedimentation tank. And the flow pump 11 is used to pump the solution to the tertiary sedimentation tank 4. If the water level in the tertiary sedimentation tank 4 is at the lowest water level at this time, the sedimentation timing will start after the solution is pumped out. If the water level in the tertiary sedimentation tank 4 is higher than the lowest water level at this time, the timing function will be restarted after the solution is pumped in. After the timing ends, the system starts the fifth solenoid valve 13 to discharge the wastewater. The wastewater containing the material is subjected to multi-stage sedimentation treatment using a physical precipitation method, so that the material contained in the wastewater can be precipitated and recovered as much as possible, thereby effectively avoiding the waste of material. No treatment agent needs to be added during the treatment process, and no pollution is caused to the material. The obtained material can be reused after normal production treatment, while saving time and cost.

[0027] Furthermore, a collecting mechanism 6 connected thereto is installed at the bottom of the primary sedimentation tank 1 , the first and second sedimentation tanks 2 , the second and second sedimentation tanks 3 and the tertiary sedimentation tank 4 .

[0028] The collecting mechanism 6 includes a collecting bucket 602 , a threaded sleeve 607 is provided on the bottom of the collecting bucket 602 , and a collecting box 601 connected to the threaded sleeve 607 is installed at the bottom of the threaded sleeve 607 .

[0029] Furthermore, a pressure sensor 605 is fixedly installed on the top of the inner cavity of the collection box 601. A control valve 606 is installed on the top of the inner cavity of the collection box 601. The control end of the control valve 606 extends to the outside of the collection box 601 and is fixedly connected to a handwheel 603.

[0030] Furthermore, a sealing box 609 is fixedly connected to the inner wall of the collection box 601, an air pump 608 is installed inside the sealing box 609, a controller 610 is fixedly installed on the surface of the air pump 608, and the air outlet end of the air pump 608 is connected to an air outlet pipe 604, which extends to the outside of the collection box 601.

[0031] Furthermore, the air inlet end of the air pump 608 is connected to an air extraction pipe 611 , which extends to the top of the inner cavity of the collection box 601 and is connected to a one-way valve 612 .

[0032] By setting up the collecting mechanism 6, it is convenient to collect the diamond powder precipitated in the first sedimentation tank 1, the first and second sedimentation tanks 2, the second and second sedimentation tanks 3 and the tertiary sedimentation tank 4. The air pump 608 is started in advance. The air pump 608 extracts the air inside the collection box 601 through the exhaust pipe 611 and the one-way valve 612, and discharges it to the outside through the outlet pipe 604, so that the inside of the collection box 601 is in a vacuum negative pressure state. The pressure sensor 605 detects the pressure signal inside the collection box 601, and the detected data is transmitted to the controller 610. When the set data is reached, the air pump 608 is turned off. The user opens the control valve 606 through the hand wheel 603 to connect the collection box 601 and the collection bucket 602. The collection box 601 is connected to the bottom of the primary sedimentation tank 1, the first and second sedimentation tanks 2, the second and second sedimentation tanks 3 and the tertiary sedimentation tank 4 respectively to extract the sediment inside them. The extracted sediment passes through the control valve 606 and enters the collection box 601 to improve the sediment collection efficiency and reduce the workload of the staff. After the extraction is completed, the threaded sleeve 607 is unscrewed from the bottom of the collection bucket 602 to disassemble the collection box 601, so that the staff can take out the sediment inside the collection box 601.
