Abstract
The invention discloses a flat-bottom suction filter comprising a suction filtering container. The flat-bottom suction filter is characterized in that the bottom of the suction filtering container is flat; the upper part of the suction filtering container is divided into a solvent layer and a solid-liquid layer from top to bottom; a supernatant outlet is arranged at one side of the solvent layer; a liquid collecting cavity is formed at the lower part of the suction filtering container; a plurality of support frames are arranged in the middle of the liquid collecting cavity; a support plate is arranged on the support frames; a filter plate is arranged on the support plate; and a filtrate outlet is arranged at the bottom at one side of the liquid collecting cavity. The flat-bottom suction filter disclosed by the invention has the advantages of simple structure, increased filter efficiency and reduced running cost.
Description
Technical field
The present invention relates to a kind of nutsch filter, be specifically related to a kind of vacuum filter that separates solidliquid mixture.
Background technology
Nutsch filter is used more extensive in chemical process, because it carries out the negative pressure leaching solid-liquid and carries out Separation of Solid and Liquid under vacuum condition, usually is used for filtering solvent and the solid material that volatility is little and have no irritating odor.The nutsch filter that uses at present; When carrying out Separation of Solid and Liquid, all liq all will pass through solid layer, and then goes out through filter cloth or other poromerics; Solid material is stayed on filter cloth or other poromerics like this, and liquid flows out the entering receiving slit from poromerics.Along with material constantly adds, filter cake thickness constantly increases, and the difficulty that makes liquid pass cake layer strengthens, and filter efficiency reduces greatly, and energy consumption is bigger.
Summary of the invention
The objective of the invention is to deficiency, a kind of flat nutsch filter of effective separation solidliquid mixture is provided to prior art.
The object of the invention can be realized through following technical scheme:
A kind of flat nutsch filter comprises the suction filtration container, it is characterized in that said suction filtration container bottom is flat; This suction filtration container top is divided into solvent layer and solid-liquid layer from top to bottom, and a side of said solvent layer is provided with the supernatant outlet, and this suction filtration container bottom is formed with the liquid collecting cavity; Be provided with some bracing frames in the middle of the liquid collecting cavity, bracing frame is provided with gripper shoe, and gripper shoe is provided with filter plate; Filter plate is provided with filter layer of cloth, and a side bottom of liquid collecting cavity has filtrate (liquid.
Said supernatant exit is provided with one deck filter cloth or poromerics.
Beneficial effect of the present invention: simple in structure, filter efficiency is high, and operating cost is low.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Among the figure: 1, suction filtration container, 2, supernatant outlet, 3, filter plate, 4, gripper shoe, 5, bracing frame, 6, the liquid collecting cavity, 7, filtrate (liquid, 8, solvent layer, 9, the solid-liquid layer.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is done further detailed explanation.
Like Fig. 1.
A kind of flat nutsch filter comprises suction filtration container 1, it is characterized in that said suction filtration container 1 bottom is flat; This suction filtration container 1 top is divided into solvent layer 8 and solid-liquid layer 9 from top to bottom, and a side of said solvent layer 8 is provided with supernatant outlet 2, and this suction filtration container 1 bottom is formed with liquid collecting cavity 6; Be provided with some bracing frames 5 in the middle of the liquid collecting cavity 6; Bracing frame 5 is provided with gripper shoe 4, and gripper shoe 4 is provided with filter plate 3, and a side bottom of liquid collecting cavity 6 has filtrate (liquid 7.Said supernatant exports 2 places and is provided with one deck filter cloth or poromerics.Also be provided with filter layer of cloth on the filter plate 3.
Solidliquid mixture is divided into solvent layer and solid-liquid layer from top to bottom after getting into and leaving standstill a period of time in the cylindrical shell; The supernatant of solvent layer directly is drawn out of through the supernatant outlet; Need not pass through thick cake layer and go out, the solid-liquid layer is through filter, and solids is stayed on the filter layer of cloth; Filtrating behind the suction filtration then gets into liquid collecting cavity, is flowed out by filtrate (liquid.
Claims (2)
1. a flat nutsch filter comprises suction filtration container (1), it is characterized in that said suction filtration container (1) bottom is for flat; This suction filtration container (1) top is divided into solvent layer (8) and solid-liquid layer (9) from top to bottom; One side of said solvent layer (8) is provided with supernatant outlet (2), and this suction filtration container (1) bottom is formed with liquid collecting cavity (6), is provided with some bracing frames (5) in the middle of the liquid collecting cavity (6); Bracing frame (5) is provided with gripper shoe (4); Gripper shoe (4) is provided with filter plate (3), and filter plate (3) is provided with filter layer of cloth, and a side bottom of liquid collecting cavity (6) has filtrate (liquid (7).
2. flat nutsch filter according to claim 1 is characterized in that said supernatant exports (2) and locates to be provided with one deck filter cloth or poromerics.
