Description
Technical field
The present invention relates to filtering technique, particularly relate to the filtering technique that a kind of dynamic filter and filter cake are handled.
Background technology
In fields such as chemical industry, medicine, food, mine, metallurgy, light textile, printing and dyeing, often need to filter the solidliquid mixture of solid particle size greater than the various concentration more than the 0.1um, need after the filtration filter cake is migrated out filter plant.It is easy filter cake being migrated out filter under normal conditions, but under the working condition that uses inflammable and explosive or high toxicity solvent, certain difficulty is arranged when solid transfer is gone out filter.
When adopting common dynamic filter as shown in Figure 1, its process is: material is in charging aperture 1 enters the cylindrical shell 2 of dynamic filter, realize filtering by the filter cloth (filter screen) on the gripper shoe 3,74,6 again, liquid phase is discharged through filtrate (liquid 5 and filtrate emptying outlet 10, solid phase then is trapped in the dynamic filter, and the filter cake of gained can be released filter with filter cake from the filtered solid outlet 9 of bottom by the opposite spin propeller.Utilize the counter-rotating propeller solid filter cake can be extruded filter press, but its resistance is big, corresponding required motor power is big, and carries out smoothly for guaranteeing to operate, and needs the auxiliary equipment of supporting frequency converter, corresponding increase equipment investment.The solid material that extrudes also need be collected and shift the also corresponding workload that increased.
Summary of the invention
At the shortcoming that exists in the above-mentioned prior art, technical problem to be solved by this invention provides a kind of needs that can satisfy various manufacturing conditions, reduce floor space, improve operating environment, reduce environmental pollution, reduce labour intensity, improve the product economy benefit, reduce the dynamic filter and the filter cake disposal of project investment.
In order to solve the problems of the technologies described above, a kind of dynamic filter provided by the present invention, comprise and be provided with the still top of stirring transmission device, the oval upper cover that connects described still top, the cylindrical shell that connects described upper cover, the taper low head and the outlet that is connected taper low head bottom that connect described cylindrical shell, described upper cover is provided with charging aperture, all be provided with gripper shoe and filter cloth on the inwall of described cylindrical shell and described taper low head, filter screen, described cylindrical shell and described taper low head are respectively equipped with filtrate (liquid, and the outlet of described taper low head bottom is filtered solid outlet and filtrate emptying outlet; It is characterized in that, on the outer wall of described cylindrical shell and described taper low head, be provided with and carry out thermoregulator chuck, can also can cool off described cylindrical shell and the heating of described taper low head, on described cylindrical shell and described taper low head, be provided with at least four heating agents and import and export.
Described chuck adopts Type of Welding to be connected with described cylindrical shell.
Gap between described chuck and the described cylindrical shell is the 20-200 millimeter, preferred 40～90 millimeters.
Described filtrate (liquid center line and described chuck up and down the distance of weld seam at the 20-400 millimeter, preferred 80～120 millimeters.
Described dynamic filter stirs and adopts screw-pushing type.
In order to solve the problems of the technologies described above, a kind of filter cake disposal provided by the present invention, its step is as follows:
A) material to be separated is in charging aperture enters dynamic filter;
B) under dynamic filter stirs, with Compressed Gas press filtration Huo Makoto suction filter, material is realized filtering by filter cloth, filter screen, and liquid phase is discharged through filtrate (liquid, and solid phase then is trapped in the dynamic filter;
C) treat filtrate row, available coordinative solvent washs filter cake, cleaning solution is leached again;
D) reach separation requirement after, close the filtrate (liquid valve, import and export to feed heating agent from heating agent filter cake heated, make the solid phase fusing or with material dissolution;
E) material is transported to pump or vacuum makes use again, finish the one action circulation;
F) before the filter cake fusing, also can add people's corresponding solvent and make the filter cake dissolving, with the form discharging of solution.
Utilize dynamic filter provided by the invention and filter cake disposal, existing dynamic filter is carried out architecture advances, the solid material that separation can be obtained melts (or dissolving) in filter inside, carry out discharging with liquid form then, can under totally enclosed condition, carry out Separation of Solid and Liquid like this, under sealing condition, wash, melt (or dissolving) and discharging after the Separation of Solid and Liquid.Dynamic filter after adopt improving can guarantee that Separation of Solid and Liquid, washing filter cakes, fusing and discharging process carry out under totally enclosed condition, and helps keeping the cleaning in production place, reduces the labour intensity of production operation simultaneously.And can carry out continuous filtration washing or repeated multiple times to material and wash and starch again and wash, thereby this machine be particularly suitable for washing require high, the material that needs repeated multiple times to wash again;
Because this dynamic filter is operated under air-tight state, thereby this machine is particularly suitable for handling the filtration washing that the existing product of inflammable and explosive, poisonous or hypertoxic danger reaches gourmet food, medicine and the biological products etc. that do not allow pollution; Can make material at the thin layer filter cake or do not have under the filter cake state and filter, thereby the rate of filtration on the unit are is very high, equipment is little and compact, and floor space is little; Easy and simple to handle, labour intensity is low; Good operational environment, non-environmental-pollution, no material is wandered away and is wasted; Can add chuck in device external, material is heated, cooling or insulation are filtered, to satisfy various process conditions.
