[0029] Please see Figure 1 This embodiment provides a sealed exhaust tank device for a centrifugal pump feeding into a storage tank, used to connect to a centrifugal pump, which is connected to a storage tank. The sealed exhaust tank device for the centrifugal pump feeding into the storage tank includes:

[0030] Exhaust canister 1, exhaust canister 1 is sealed;

[0031] Feed pump exhaust valve 2 is located outside the exhaust tank 1 and is used to connect to the outlet of the centrifugal pump.

[0032] The recycling mechanism 3 includes an exhaust valve 31 and a discharge valve 32. The exhaust valve 31 is located outside the exhaust tank 32 and is used to connect with the waste gas treatment pipeline so that the waste gas in the exhaust tank 1 is discharged through the exhaust valve 31 to the waste gas treatment pipeline and treated. The discharge valve 32 is located outside the exhaust tank 1 and is used to connect with the inlet of the centrifugal pump so that the waste in the exhaust tank 1 is discharged through the discharge valve 32 to the centrifugal pump and recycled by the storage tank.

[0033] For the above structure, during installation, the exhaust tank 1 is placed near the storage tank, the exhaust valve 2 of the feed pump is set towards the centrifugal pump of the storage tank, the exhaust valve 31 of the recovery mechanism 3 is connected to the external waste gas treatment pipeline, and the discharge valve 32 is connected to the inlet of the centrifugal pump.

[0034] Based on the above structure, during use, the operator connects the centrifugal pump outlet to the feed pump exhaust valve 2 and the centrifugal pump inlet to the discharge valve 32, and then starts the centrifugal pump. Specifically, some material in the storage tank, as well as some waste gas from the centrifugal pump and the storage tank, is driven by the centrifugal pump to enter the exhaust tank 1 through the feed pump exhaust valve 2. This causes waste and waste gas to accumulate in the exhaust tank 1. Simultaneously, the discharge valve 32 of the recovery mechanism 3 is opened, allowing the waste to enter the exhaust valve 31 and flow to the centrifugal pump. Driven by the centrifugal pump, the waste is re-poured into the storage tank, achieving waste recovery. The exhaust valve 31 of the recovery mechanism 3 is then opened, causing the gas in the exhaust tank 1 to rise and enter the external waste gas treatment channel through the exhaust valve 31, achieving waste gas recovery. After the centrifugal pump completes the venting action on the storage tank, the centrifugal pump stops operating, and the feed pump exhaust valve 2, as well as the exhaust valves 31 and 32 in the recovery mechanism 3, are closed, ending the entire process.

[0035] Furthermore, such as Figure 1 As shown, the sealed exhaust tank device of the centrifugal pump for the storage tank also includes a drain valve 4. The drain valve 4 is located on the outside of the exhaust tank 1 and is connected to the waste bin so that the waste in the exhaust tank 1 is discharged to the waste bin through the drain valve 4. Specifically, the main function of the drain valve 4 is to discharge the residual waste in the exhaust tank 1 under certain circumstances to clean the exhaust tank 1, or to empty the original internal residues and waste when it is necessary to change the type of chemical material contained in the exhaust tank 1, so as to avoid cross-contamination between waste materials and affect recycling.

[0036] Based on the above-described drain valve 4 structure, in another embodiment, the drain valve 4 is disposed on the bottom surface of the exhaust tank 1, and on the side of the bottom surface of the exhaust tank 1 away from the discharge valve 32. Therefore, the drain valve 4 is mainly used to discharge waste material deposited at the bottom of the exhaust tank 1. Under the action of gravity, liquid always flows downwards and accumulates at the bottom. Installing the drain valve 4 at the bottom ensures that all residual liquid is effectively discharged, preventing long-term liquid stagnation. In the above embodiment, the drain valve 4 is set to a 1 / 2-inch pipe size, which meets the flow rate requirement for discharging some residual waste material.

[0037] Furthermore, the feed pump exhaust valve 2 is located on the vertical side wall of the exhaust tank 1, and the feed pump exhaust valve 2 has a 1 / 2-inch pipe size. Specifically, the feed pump exhaust valve 2 is located slightly above the side wall, facilitating the connection of external waste materials and exhaust gas, allowing the waste materials to flow down the wall surface and preventing splashing. The feed pump exhaust valve 2 is set to a 1 / 2-inch pipe size to meet the required feed flow rate.

[0038] Furthermore, an exhaust valve 31 is located on the top surface of the exhaust tank 1, and the exhaust valve is a 1 / 2-inch tube. Specifically, due to the low density and high buoyancy of the gas, the exhaust gas will naturally rise and accumulate at the highest point of the exhaust tank 1. Therefore, installing an exhaust valve 31 at the top of the exhaust tank 1 can conveniently discharge the exhaust gas in the system.

[0039] Furthermore, the discharge valve 32 is located on the bottom surface of the exhaust tank 1, and the discharge valve 32 is a 1-inch pipe. Similarly, under the influence of gravity, liquid will always flow downwards and accumulate at the bottom. Installing the discharge valve 32 at the bottom ensures that all residual liquid is effectively discharged, preventing long-term liquid stagnation. The difference is that in this embodiment, the discharge valve 32 is set as a 1-inch pipe with a larger diameter, which can avoid the resistance of the exhaust tank 1 wall to the liquid and improve the waste liquid recovery efficiency.

[0040] The above-disclosed content is only a preferred and feasible embodiment of the present utility model, and is not intended to limit the scope of the patent application of the present utility model. Therefore, all equivalent technical changes made using the contents of the present utility model specification and drawings are included in the scope of the patent application of the present utility model.

[0041] The various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.

[0042] Although this application has been described by way of examples, those skilled in the art will know that this application has many modifications and variations without departing from the spirit of this application, and it is intended that the appended embodiments include these modifications and variations without departing from this application.
