Description

Technical Field

[0001] The utility model relates to the technical field of vacuum filtration, and particularly relates to a vacuum filtration system. Background Art

[0002] During industrial production, gases containing a large amount of electrolyte and impurities or pollutants will be generated, and a small amount of electrolyte will also be rich in the gases; after the gases are directly discharged, they will have an impact on the surrounding environment, so purification treatment needs to be carried out before discharge. In the prior art, a vacuum filtration system is used to separate gas and liquid.

[0003] There are some problems in the technical solutions of the existing vacuum filtration systems in practical applications. The existing vacuum filtration systems use liquid to overflow the baffle, allowing the gas and liquid to enter the water and then be discharged to achieve the effect of gas-liquid separation. A filter is set at the inlet end to filter garbage, but the effect is not ideal, and the separation and filtration effects are relatively low.

[0004] Therefore, it is very necessary to invent a vacuum filtration system to solve the above problems. Content of the Utility Model

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] The present utility model provides a vacuum filtration system as Figures 1-4 shown, which includes a lower bottom plate 1. In the middle of the upper surface of the lower bottom plate 1, a cylinder 2 is fixedly arranged. The top end of the cylinder 2 is fixedly arranged with an upper cover plate 3 through bolts. On the lower surface of the upper cover plate 3, an inner pressing plate 4 is fixedly arranged through bolts. Below the inner pressing plate 4, an extension seat 5 is arranged, and a plurality of connecting screw rods 6 are fixedly arranged between the extension seat 5 and the inner pressing plate 4. Between the extension seat 5 and the inner pressing plate 4, a plurality of inner filter mesh cylinders 7 are arranged. The cross-section of the inner filter mesh cylinder 7 is arranged in a waveform structure, and the plurality of inner filter mesh cylinders 7 are nested with each other. The extension seat 5 and the plurality of inner filter mesh cylinders 7 cooperate to achieve the effect of multiple filtrations. Moreover, the cross-section of the inner filter mesh cylinder 7 is arranged in a waveform structure, which improves the contact area between the mixture and the inner filter mesh cylinder 7, thereby improving the filtration and separation effect of the device.

[0022] Specifically, a discharge pipe 9 is penetrated through the top end of the inner pressing plate 4. The bottom end of the discharge pipe 9 extends into the innermost inner filter mesh cylinder 7, and the top end of the discharge pipe 9 extends to the outside of the cylinder 2. At one end of the upper surface of the lower bottom plate 1, a vacuum pump 10 is fixedly arranged. The input end of the vacuum pump 10 is fixedly arranged with an inlet vacuum pipeline 11, and one end of the inlet vacuum pipeline 11 is arranged at the top end inside the cylinder 2. A one-way valve 12 is fixedly arranged in the middle of the inlet vacuum pipeline 11. The output end of the vacuum pump 10 is fixedly arranged with an outlet vacuum pipeline 13. The vacuum pump 10 acts on the cylinder 2 through the inlet vacuum pipeline 11, making a negative pressure generated at the top end inside the cylinder 2.

[0023] More specifically, in the middle of the outer side wall of the cylinder 2, a feed pipe 14 is fixedly arranged, and the position of the feed pipe 14 is flush with the bottom end of the inner conical cover 8. At the top end of the cylinder 2, a vacuum pressure gauge 15 is fixedly arranged. The setting of the vacuum pressure gauge 15 facilitates monitoring the air pressure inside the cylinder 2.

[0024] Furthermore, at the four corners of the lower surface of the lower bottom plate 1, universal locking wheels 16 are fixedly arranged, and the universal locking wheels 16 are set as self-locking universal wheels. The setting of the universal locking wheels 16 facilitates the movement of the device. At the bottom end of the outer side wall of the cylinder 2, a lower cover plate 17 is fixedly arranged. Handles are fixedly arranged on the outer side walls of both the lower cover plate 17 and the upper cover plate 3. After the lower cover plate 17 is removed, the impurities and garbage separated at the bottom end inside the cylinder 2 can be cleaned.

[0025] Working principle of the utility model:

[0026] When this device is in use, the vacuum pump 10 acts on the cylinder body 2 through the vacuum inlet pipe 11, causing negative pressure to be generated at the top inside the cylinder body 2. The gas-liquid mixture to be treated is transported into the inside of the cylinder body 2 through the feed pipe 14. The gas-liquid mixture moves along the surface of the inner conical cover 8 under the action of negative pressure. At this time, the gas-liquid mixture makes a spiral movement around the inner conical cover 8. During the movement, the impurities in the gas-liquid mixture are separated due to different centrifugal forces to achieve the separation of impurity garbage. Then the gas-liquid mixture moves upward to the outside of the inner filter screen cylinder 7. At this time, the gas and liquid in the gas-liquid mixture are separated under the action of the inner filter screen cylinder 7. The separated waste gas is discharged under the action of the vacuum pump 10, and the liquid is discharged from the device through the discharge pipe 9 inside the inner filter screen cylinder 7. Thus, the filtration and separation treatment of the gas-liquid mixture can be realized.

[0027] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model.
