[0004] The technical solution of the utility model is an integrated vacuum device for a plastic profile sizing water tank, including a vacuum storage tank connected to an external vacuum extraction device. A vacuum sensor, a water level probe, and a vacuum gauge are arranged on the vacuum storage tank. The vacuum storage tank is externally connected to a drain pipe and a vacuum main pipe. The drain pipe is connected to a drain pump. A series of vacuum branch pipes are connected in parallel on the vacuum main pipe. Each vacuum branch pipe is connected to a corresponding plastic profile vacuum sizing device. An independent vacuum pump is arranged on each plastic profile vacuum sizing device. A vacuum regulating valve and a pneumatic angle seat valve are connected to the vacuum branch pipe.
[0005] Preferably, an exhaust main pipe is externally connected to the vacuum storage tank. A valve and a check valve are connected to the exhaust main pipe. The exhaust main pipe is externally connected to a vacuum pump for vacuum extraction; the drain pump and the exhaust main pipe are connected through a linear flexible joint.

DETAILED DESCRIPTION
[0010] The utility model is further described in detail below in conjunction with the accompanying drawings.
[0011] like Figure 1 As shown, the utility model provides a plastic profile shaping water tank integrated vacuum equipment, including a vacuum storage tank 1 of an external vacuum extraction device, the vacuum storage tank 1 is provided with a vacuum sensor 2, a water level probe 3 and a vacuum gauge 4, the vacuum storage tank 1 is externally connected with a drain pipe 5 and a vacuum main pipe 6, the drain pipe 5 is connected to a drain pump 7, a series of vacuum branch pipes 8 are connected in parallel to the vacuum main pipe 6, each vacuum branch pipe 8 is connected to a corresponding plastic profile vacuum shaping equipment, each plastic profile vacuum shaping equipment is provided with an independent vacuum pump, and the vacuum branch pipe 8 is connected to a vacuum regulating valve 9 and a pneumatic angle seat valve 10.
[0012] In the above scheme, the vacuum storage tank 1 has an exhaust pipe 11 outside, the exhaust pipe 11 is connected with a valve 12 and a one-way valve 13, and the exhaust pipe 11 is externally connected to a vacuum pump for vacuuming; the drainage pump 7 and the exhaust pipe 11 are connected via a linear flexible joint 14.
[0013] In addition, the drain pipe 5 is provided with a one-way valve and a valve.
[0014] At the beginning of the vacuum shaping production of plastic profiles, the utility model relies on the vacuum pump installed on the equipment to start producing pipes. When the pipe production is in a normal extrusion condition, the system switches to the vacuum storage tank 1 to provide the vacuum required by the equipment. When the equipment is in normal production, it continues to rely on the vacuum storage tank 1 to provide a vacuum shaping environment. If a certain equipment fails, the system controls the valve on the corresponding vacuum branch pipe 8 to close, which will not affect the normal production of equipment on other production lines.
[0015] In a normal working environment of the vacuum storage tank 1 , water generated inside will accumulate at the bottom of the vacuum storage tank. When the water accumulates to the position of the water level probe, the drainage pump 7 starts to pump out the water inside.

Any simple modifications, equivalent changes or decorations made to the above embodiments based on the technical principles of the present utility model still fall within the scope of the technical solutions of the present utility model.
