A first part: continuous vacuum pumping
The device mainly comprises a vacuum pump or a negative pressure fan, two independently controlled vacuum recovery tank combinations, various air circuits, an automatic waterway switching valve, a fan protection and filtration device, a sewage pump, an integrated controller, a frame structure and the like.
When the vacuum recovery works, the two vacuum recovery tanks establish vacuum through a vacuum pump (or a negative pressure fan), and the two vacuum recovery tanks can work independently in turn or simultaneously according to program setting.
When one of the vacuum recovery tanks equipped with the electronic level meter is full of sewage, the system automatically opens the air intake valve and the blow-down valve of the tank and closes the vacuum recovery inlet valve (water suction port), at this time, the tank loses negative pressure and begins to discharge sewage under normal atmospheric pressure.
Meanwhile, the other vacuum recovery tank which is emptied, closes the steam-water mixture discharge port and is in a vacuum standby state is synchronously started to work, and sewage pumped back from the collecting device is automatically switched to the vacuum recovery tank, so that continuous vacuum pumping and draining operation is realized.
After the discharge valve of the vacuum recovery tank in the discharge working state is automatically opened, sewage and sludge are rapidly discharged through the bottom discharge pipeline under the action of gravity and suction force of the pump, when the sewage in the tank is completely discharged or reaches the lowest water level, the discharge valve and the top evacuation valve are automatically closed, and meanwhile, the valve connected with the vacuum pump is automatically opened to start to establish vacuum negative pressure and keep the negative pressure standby working state.
The two tanks are circularly reciprocated in this way, and the continuous and uninterrupted vacuum pumping and discharging function is realized.
The vacuum recovery tank is designed with a manhole for maintenance, which is used for regular maintenance work.
Self-cleaning function.

Measures for protecting the vacuum pump:
1) an in-tank shielding plate:
in order to avoid the damage of the pump caused by the fact that a large amount of sludge-containing steam-water mixture enters the fan blade, a baffle plate structure is designed at the top in the vacuum recovery tank and below the tank outlet connected with the negative pressure fan. The vapor-water mixture entering the vacuum recovery tank at high speed along the tangential direction through the sewage recovery suction pipe forms a cyclone effect, decelerates in the tank, spirally descends for deposition, and a small amount of splashes are intercepted by the top baffle plate and return to the bottom of the tank again.
2) A steam-water separation filter:
a negative pressure steam-water separator (a product in the prior art) is arranged on a pipeline between the vacuum recovery tank and the negative pressure fan. The separator has an openable upper cover, a discharge port at the bottom, and a multi-layer composite structure wire mesh filter or plastic ball filter or other fibrous material filter mounted therein. A small amount of mud-containing steam-water mixture pumped to the air inlet pipeline of the fan is intercepted and filtered again by the metal wire mesh filter in the water mist filter, water is intercepted, and only filtered clean air can be discharged through the fan blade, so that the fan is prevented from being damaged.
The bottom of the steam-water separator is provided with a discharge port, so that the filtering device can be cleaned regularly.
The sewage discharge pipelines of the two tanks are connected to a sewage pump through the collection of a four-way connecting piece and a valve, and the four-way connecting piece is provided with an opening which is used for overhauling and cleaning the sewage discharge pipelines and is provided with a plug or the valve. The sewage passes through the sewage pump and then has two passages, one passage is directly discharged, and the sewage which is not subjected to separation treatment can be directly discharged by opening the valve. The other path enters a solid-liquid separation water treatment device at the next section.
A second part: solid-liquid separation water treatment device
The device selects a product waste liquid treatment system in the prior art, and comprises a screw-stacking machine type pressurizing and filtering device with compact layout, two dosing proportioning mixers with independent metering pumps and stirring devices, an integrated controller, a dry mud output port, a clear water discharge port, an overflow channel, a self-cleaning device and the like.
When the sewage containing paint, rust, soil and metal powder recovered in vacuum is injected into a solid-liquid separation device, a dosing and stirring device starts to work, and a medicament is added into the sewage in proportion to ensure that solid particles are rapidly flocculated and settled, and water is squeezed out through filter pressing to become dehydrated sludge. And is discharged through a slag discharge channel. The purified water is discharged through the discharge port. During this period, a set of spray cleaning nozzles self-cleans the filter element assembly.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof.
