Abstract
The utility model belongs to the technical field of the liquid filtration, and relates to a filter tank for manufacturing and calcining an alkali filtering caustification liquid. The filter tank comprises a tank body, a supporting grid, an iron wire mesh, a filter cloth, a vacuum tube and a caustification liquid outlet tube. The rectangular tank body of the length of 20 cm, the width of 150 cm and the height of 100 cm is welded with an iron plate of the thickness of 0.3 cm firstly; a steel bar of the diameter of 0.8 cm is welded in the position 45 cm away from the bottom part of the tank body along a long edge every 25 cm as the supporting grid; the iron wire mesh is paved on the supporting grids; the filter cloth is also paved on the iron wire mesh; the vacuum tube is mounted on one side 25 cm away from the bottom part of the tank body; and the caustification liquid outlet pipe is mounted at the bottom part. The utility model has the advantages of investment conservation, simple manufacture and good effect, and is suitable for manufacturing and calcining the alkali in small-scale chemical enterprises.
Description
Technical field:
The utility model belongs to the liquid filtering technical field, relates to a kind of filter vat that caustic soda filters causticization liquid that is used for making.
Background technology:
In with causticization legal system caustic soda process, filtration is one important procedure.At present the used filter plant of large chemical complex is more complete, but needs investment very big, and general little chemical enterprise is difficult to bear, and what obtain is reduced investment, effective and practical filter plant so little chemical enterprise is desired.
Summary of the invention:
The purpose of this utility model is the investment that can bear at little chemical enterprise, and a kind of filter vat that caustic soda filters causticization liquid that is used for making is provided.
The technical scheme that the utility model adopted: it comprises cell body, support grid, wire netting, filter cloth, valve tube, causticization liquid outlet pipe, earlier with the thick iron plate weldering system one long 200cm of 0.3cm, the rectangle cell body of wide 150cm, high 100cm, make support grid along long limit every the reinforcing bar of a diameter 0.8cm of 25cm weldering system from end 45cm place at cell body again, on support grid, spread wire netting again, filter cloth on the wire netting upper berth again, from end 25cm place one side a valve tube is installed at cell body again, a causticization liquid outlet pipe is installed in the bottom again.
Described filter cloth is with calico or woven asbesto.
Described causticization liquid outlet pipe, the installation site can be in the optional position, bottom.
Principle of the present utility model: causticization liquid is put into cell body place and begin above the filter cloth to filter, under the vacuum pump suction function, make cell body bottom air form negative pressure,, flow out from bottom causticization liquid outlet pipe through the filtering causticization liquid of filter cloth to accelerate filtration velocity.
The utlity model has following advantage: reduced investment, simple, respond well, the suitable little chemical enterprise system caustic soda of making use.
