Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below by referring to the drawings are exemplary only for explaining the present invention, and should not be construed as limiting the present invention.
It should be noted that the terms of orientation such as up, down, inside and outside in the embodiments of the present invention are only relative concepts or reference to the normal use state of the product, and should not be considered as limiting.
The first embodiment is as follows:
as shown in fig. 1, a vacuum purification apparatus includes a sealed housing 5, a filter screen 3 and a baffle 8 disposed in a vertically staggered manner are disposed inside the sealed housing 5, and the baffle 8 is disposed below the filter screen 3. Preferably, the number of baffle 8 is two at least, and this embodiment is two, and two adjacent baffle 8 boards are the reverse slope setting, and the height of baffle 8 one end of fixing on the casing 5 inner wall is higher than the height of the other end, and this kind of structural design for by the gathering of the mud after the vacuum gasification on baffle 8, purifying effect is good. The bottom plate 9 slope setting of casing 5, the air inlet of being connected with negative pressure admission line 7 is seted up to 5 one side bottoms of casing of higher one end, and the drain of being connected with sewage pipes 1 is seted up to 5 one side bottoms of casing of lower one end, and in this embodiment, the drain has been seted up to 5 left sides bottoms of casing, and the air inlet has been seted up to right side bottom. The air inlet and the sewage draining exit are both arranged below the baffle 8, and the height of the air inlet is higher than that of the sewage draining exit. An adsorption port connected with an adsorption pipeline 4 is formed in the shell 5 above the filter screen 3, and the shell is connected with a vacuum generator (not shown in the figure) through the adsorption pipeline 4; preferably, the adsorption port is formed in a top plate of the housing 5, the top plate is detachably and hermetically connected to the housing 5, and the filter screen 3 can be conveniently replaced through the detachable top plate. The sewage draining pipeline 1 is provided with a sewage draining valve 2, and the negative pressure air inlet pipeline 7 is provided with an adjusting valve 6 for adjusting vacuum pressure.
When the vacuum generator works, the blowdown valve 2 is closed, and the vacuum pressure in the whole vacuum adsorption system is adjusted by operating the adjusting valve 6, so that the system is stable. Gas gets into in the casing 5 through negative pressure admission line 7, under the effect of baffle 8, makes by the gathering of mud after vacuum gasification on baffle 8, condenses into the drop of water, makes the lower one end of condensed drop of water collection to casing bottom plate 9, and the lower one end of bottom plate 9 indicates bottom plate 9 left end in this embodiment. Solid particles are transited through the filter screen 3, when sewage needs to be discharged, the vacuum generator is stopped, the sewage discharge valve 2 is opened, and the solid particles are discharged out of the shell through the sewage discharge pipeline.
Example two:
as shown in fig. 2, the present embodiment is different from the first embodiment in that: the filter screen is characterized by further comprising a pulse valve 10, a pulse port connected with the pulse valve 10 is formed in the shell 5 above the filter screen 3, and the pulse valve 10 is communicated with the shell through a pulse valve communicating pipeline 11.
