Technical Field

[0001] This utility model relates to the field of waste liquid treatment technology, specifically to an extraction and regeneration device for waste liquid at the outlet of a vacuum pump. Background Technology

[0002] Vacuum pumps are widely used in industries such as chemical, pharmaceutical, and electronics manufacturing to extract air or other gases. During operation, the vacuum pump's outlet carries a certain amount of waste liquid. This waste liquid typically consists of gas condensate, lubricating oil, and residual solvents from the process, characterized by complex composition, high pollutant concentration, and difficulty in treatment. Traditional waste liquid treatment methods mainly involve collection and incineration or transfer to centralized treatment facilities. These methods suffer from high costs, high energy consumption, and low recovery efficiency, increasing operating costs for enterprises and causing serious environmental pollution.

[0003] Currently, some waste liquid recovery devices are available on the market, including equipment that treats waste liquid through multi-stage separation, filtration, and adsorption. For example, patent (CN102220316B) proposes a waste liquid recovery device based on separation membrane technology, which achieves oil-water separation and pollutant removal by filtering waste liquid through a separation membrane. However, these technologies still have the following problems:

[0004] 1. Ineffective recovery of dissolved organic components in waste liquid: Traditional separation membrane technology or adsorption method is difficult to completely remove dissolved organic matter in waste liquid, resulting in the recovered liquid (regenerated liquid) still containing a certain amount of pollutants, which cannot be directly reused; 2. Complex operation and high maintenance cost: Existing equipment usually requires frequent replacement of filter membranes or adsorption materials, which increases the operating and maintenance costs.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3 This utility model provides a technical solution: an extraction and regeneration device for waste liquid from the outlet of a vacuum pump, comprising a support 1, a water tank 2 rotatably mounted on the support 1, and a driving component on the support 1 to drive the rotation of the water tank 2, thereby mixing the liquid inside the water tank 2 and improving the extraction effect; a transparent observation window 21 is provided on the side wall of the water tank 2, and a transparent main discharge pipe 6 is provided at the bottom of the support 1, allowing real-time observation of the positions of the aqueous and oil phases during the liquid discharge process through the transparent observation window 21 and the transparent main discharge pipe 6, facilitating the separate discharge and collection of the aqueous and oil phases; a lower discharge port 61 is provided at the lower side of the main discharge pipe 6, and an upper discharge port 62 is provided at the upper side of the main discharge pipe 6, with the lower discharge port 61 and the upper discharge port 62 respectively used to collect liquids of different phases, facilitating the separate discharge and collection of the aqueous and oil phases.

[0022] The lower part of the inside of water tank 2 is funnel-shaped, so that the liquid can automatically collect at the main discharge pipe 6 when it is discharged.

[0023] The section between the lower discharge port 61 and the upper discharge port 62 in the main discharge pipe 6 can temporarily store the liquid at the separation point of the aqueous and oil phases. After the aqueous and oil phase liquids are discharged, the liquid at the separation point of the aqueous and oil phases is discharged last.

[0024] Furthermore, when directly using a stirrer to stir the liquid inside, as the liquid is inserted into the aqueous phase at the bottom for stirring, the liquid level gradually drops during the discharge of the aqueous phase. Aquatic liquid residue remains on the stirrer and then mixes with the descending oil phase, thus contaminating the oil phase. Therefore, an external drive method is used to mix the liquid by rotating the water tank 2. The drive component includes a servo motor 4 mounted on the bracket 1. The output shaft of the servo motor 4 is equipped with a drive disk 41, and the water tank 2 is equipped with an annular rubber ring 5 on the peripheral side corresponding to the drive disk 41. The drive disk 41 applies a certain squeezing force to the annular rubber ring 5, so that when the drive disk 41 rotates, it can drive the water tank 2 to rotate through the annular rubber ring 5.

[0025] Furthermore, the cross-section of the inner cavity of water tank 2 is a regular hexagonal structure, and the inner corners of the regular hexagon are chamfered. This structure can generate more local turbulence and eddies during the stirring process, breaking the symmetrical laminar flow mode in the circular barrel, thereby improving the mixing uniformity.

[0026] Furthermore, a main sealing plug 7 is movably inserted inside the main discharge pipe 6. A pull rod 71 is provided at the bottom of the main sealing plug 7, and an annular edge is provided at the lower end of the inner side of the main discharge pipe 6 to limit the main sealing plug 7. A secondary sealing plug 8 is movably inserted inside the upper discharge port 62, and the insertion end of the secondary sealing plug 8 can penetrate the upper discharge port 62 and extend to the lower side of the main sealing plug 7. The secondary sealing plug 8 can limit and block the main sealing plug 7. In addition, the pull rod 71 can drive the main sealing plug 7 to move up and down, thereby opening the lower discharge port 61 to facilitate the discharge of aqueous phase liquid. Oil phase liquid can be discharged through the upper discharge port 62.

[0027] Furthermore, the water tank 2 is provided with a cover plate 3, and the cover plate 3 is provided with an air outlet pipe and a connecting pipe for connecting to a vacuum pump.

[0028] Furthermore, two storage tanks 9 are provided on the upper side of the water tank 2, and the bottom of the storage tank 9 is provided with a liquid outlet pipe that communicates with the water tank 2. A valve is provided on the liquid outlet pipe. The two storage tanks 9 are used to store water circulating liquid and oil circulating liquid, respectively.

[0029] The servo motor 4 used in this utility model is a commonly used electronic component in the prior art. Its working method and circuit structure are well-known technologies and will not be described in detail here.

[0030] When using:

[0031] Taking the example of a vacuum pump outlet gas containing aqueous waste liquid, this aqueous solution is considered a regenerated liquid:

[0032] Connect the outlet of the vacuum pump to the connecting pipe on the cover plate 3. The gas containing waste liquid discharged from the outlet of the vacuum pump enters the water tank 2. The gas is discharged through the outlet pipe, and the waste liquid falls into the water tank 2 under the action of gravity.

[0033] Open the valve of the storage tank 9 containing the oil phase circulating liquid, and the oil phase circulating liquid enters the water tank 2, thereby extracting the aqueous phase waste liquid;

[0034] The servo motor 4 is controlled by an external switch. The servo motor 4 drives the drive disk 41 to rotate. Under the action of friction, the drive disk 41 drives the water tank 2 to rotate through the annular rubber ring 5. During the rotation of the water tank 2, the liquid inside it is mixed.

[0035] Then let it stand for a period of time to allow the aqueous and oil phases to separate into layers;

[0036] During discharge, the separation of water and oil phases can be observed in real time through the transparent observation window 21 and the transparent main discharge pipe 6.

[0037] Pull the secondary sealing plug 8 horizontally a certain distance so that it no longer obstructs the downward movement of the main sealing plug 7, and then pull the main sealing plug 7 downward to make the lower discharge port 61 unobstructed. At this time, the aqueous solution is discharged through the lower discharge port 61, which is convenient for recycling.

[0038] When the water phase and oil phase are separated near the bottom of the inner cavity of the water tank 2, the main sealing plug 7 is pushed upward by the pull rod 71, which greatly reduces the cross-section of the liquid inlet of the lower discharge port 61, thereby slowing down the liquid discharge rate.

[0039] When the water phase and oil phase stratification point is located between the lower discharge port 61 and the upper discharge port 62 and is close to the top of the main sealing plug 7, push the upper main sealing plug 7 upward again to close the lower discharge port 61. It is necessary to ensure that the water phase and oil phase stratification point is located between the lower discharge port 61 and the upper discharge port 62. If the water phase and oil phase stratification point corresponds to the upper discharge port 62, repeat this step.

[0040] Then open the secondary sealing plug 8 to allow the oil phase liquid to be discharged through the upper discharge port 62;

[0041] After the oil phase liquid is discharged, replace the container outside the upper discharge port 62, push the main sealing plug 7 up to allow the liquid at the water phase and oil phase separation to be discharged through the upper discharge port 62; or pull the main sealing plug 7 down to allow the liquid at the water phase and oil phase separation to be discharged through the lower discharge port 61.

[0042] This invention uses extraction to remove dissolved organic matter from waste liquid, achieving efficient separation and recycling of waste liquid while reducing environmental pollution. Furthermore, the state of the regenerated liquid can be observed during the waste liquid discharge process to ensure that the discharge of the regenerated liquid is clean, achieving a higher treatment effect. In addition, the device is simple to operate, has low operating and maintenance costs, and is convenient to use.

Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
