Abstract
The utility model relates to a kind of positive/negative-pressure associating flame filter press, be made up of frame, hold down gag, filter plate, vacuum extractor, control system, hold down gag, filter plate are separately fixed in frame, control system controls hold down gag, vacuum extractor is connected with the undercurrent seal of tube of filter plate water outlet, and material is combined into a confined space be interconnected near the space between the one side and filter plate of filter plate and undercurrent pipe, vavuum pump.When board and frame machine charging of the present utility model and twice pressing; both normal pressure can be provided by pump lift or the medium such as water, gas; negative pressure can be formed by vacuum extractor at the water surface that goes out of filter material again simultaneously; reduce the atmospheric pressure of material water outlet side; improve the pressure differential inside and outside filter material; both the filter efficiency of material can have been increased substantially; reduce the moisture content after material dewatering; the pressure that when also reducing charging, twice pressing, frame, filter plate, hold down gag bear simultaneously, proterctive equipment.
Description
Technical field
The utility model belongs to mechanical engineering field, a kind of for slurry by filtration, content liquid in material is reduced, form the plant equipment of plasticity pie material, when can make material filtering, also negative pressure is subject to while being subject to normal pressure, in frame, hold down gag, when the pressure that filter plate bears is constant, charging and the squeeze pressure of material can be increased substantially, increase substantially the pressure differential of material feeding end and water side, the filter efficiency of material can be increased substantially and improve filter material solid content, be specifically related to a kind of positive/negative-pressure associating flame filter press.
Background technology
Existing plate and frame filter press is made up of frame, hold down gag, filter plate and control system, the piezodielectric that has provided by means of only pump or air compressor machine applies normal pressure to filter material, in certain frame, hold down gag and filter plate situation, the pressure that can provide and bear is limited, also limit filter efficiency and filter effect simultaneously, especially for the dirty mud, organic materials etc. that are difficult to filter, efficiency and effect have received and greatly limit, and even cannot select flame filter press.
Summary of the invention
The problems referred to above and deficiency is there is in the purpose of this utility model in order to overcome present technology, a kind of positive/negative-pressure is provided to combine flame filter press, when board and frame machine charging of the present utility model and twice pressing, both pump lift or water can be passed through, the media such as gas provide normal pressure, negative pressure can be formed by vacuum extractor at the water surface that goes out of filter material again simultaneously, reduce the atmospheric pressure of material water outlet side, improve the pressure differential inside and outside filter material, both the filter efficiency of material can have been increased substantially, reduce the moisture content after material dewatering, also reduce charging simultaneously, frame during twice pressing, filter plate, the pressure that hold down gag bears, proterctive equipment.
The technical solution of the utility model is:
A kind of positive/negative-pressure associating flame filter press, be made up of frame, hold down gag, filter plate, vacuum extractor, control system, hold down gag, filter plate are separately fixed in frame, control system controls hold down gag, it is characterized in that: vacuum extractor is connected with the undercurrent seal of tube of filter plate water outlet, material is combined into a confined space be interconnected near the space between the one side and filter plate of filter plate and undercurrent pipe, vavuum pump.
The utility model makes vacuum extractor and charging open by control system simultaneously, terminates with twice pressing simultaneously.
Design principle of the present utility model and the course of work are:
The utility model is the normal pressure utilizing pump or air compressor machine to provide is executed stressed to filter material while, reduce the air pressure of material water outlet side, improve the feed end of material and the pressure differential of water side, also negative pressure is subject to while being subject to normal pressure, when the pressure that frame, hold down gag, filter plate bear is constant, charging and the squeeze pressure of material can be increased substantially, increase substantially the pressure differential of material feeding end and water side, increase substantially filter efficiency and improve material solid content.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, the utility model is made up of frame 1, hold down gag 2, filter plate 3, vacuum extractor 4 and control system 5, hold down gag 2, filter plate 3 are separately fixed in frame 1, control system 5 controls hold down gag, wherein vacuum extractor 4 is connected with the undercurrent seal of tube of filter plate 3 water outlet, and material is combined into a confined space be interconnected near the space between the one side and filter plate of filter plate and undercurrent pipe, vavuum pump.By control system 5, vacuum extractor and charging are opened simultaneously, terminate with twice pressing simultaneously.Frame 1, hold down gag 2, filter plate 3, vacuum extractor 4 and control system 5 are all existing structures.
The utility model is the normal pressure utilizing pump or air compressor machine to provide is executed stressed to filter material while, reduce the air pressure of material water outlet side, improve the feed end of material and the pressure differential of water side, also negative pressure is subject to while being subject to normal pressure, when the pressure that frame, hold down gag, filter plate bear is constant, charging and the squeeze pressure of material can be increased substantially, increase substantially the pressure differential of material feeding end and water side, increase substantially filter efficiency and improve material solid content.
