The service life of pipeline and equipment.
Traditional bottom filters method, receives hydraulic pipeline and is arranged in the filtering layer of filter tank bottom, drainage is by natural filtration through receiving hydraulic pipeline stream
Enter in hot-tub, filter tank and hot-tub are two spaces separated independently of each other.Natural filtration, pulp water natural separation take compared with
It is long, it can influence to grab the linking of slag flow chart, to ensure that the compactedness of technique can occur to grab the operating mode of slag with water, working environment is more
Badly；Bottom hot-tub, is individually present, and need to set inspection manhole, and inevitable hot water flue gas escapes.Receive water system and be placed in filtering layer
In, setting is more complicated, and piping lane pipeline is more and nearer apart from hot-tub, and hot water flue gas is to piping lane pipeline and service life of equipment
Have a great influence.
In a word, at the top of filter tank and bottom hot-tub flue gas aggregation, be always puzzlement slag handling system designer and
The a great problem of iron-smelter operating personnel.
Utility model content
The deficiencies in the prior art in view of the above, the purpose of this utility model are to provide that a kind of flow is short, rhythm is fast,
And the filter tank for reducing flue gas to producing and safeguarding influence that can try one's best.
In order to achieve the above objects and other related objects, technical solutions of the utility model are as follows：
The filter tank that a kind of filtering layer connects with hot-tub, including filter tank and the filtering layer supporting part being arranged in filter tank and multistage filter
Layer, the multistage filtering layer are supported on above filtering layer supporting part, the filtering layer supporting part hot-tub formed below, above multistage filtering layer
For pulp water mixed zone, the filtering layer supporting part has water hole, and the hot-tub connects through water hole with multistage filtering layer.
Multistage filtering layer, filtering layer supporting part, hot-tub one arrangement, i.e., slag-water slurry, multistage filtering layer and bottom in filter tank
Filter water is in same connection container in hot-tub.Cancel independent external hot-tub, in the absence of bottom hot-tub flue gas
Produce.Reduce flue gas aggregation.
Further, the hot-tub is arranged at filter tank bottom.
Further, in addition to by pipeline the elevator pump being connected with hot-tub, the elevator pump makes to be formed in filter tank during work
Certain negative pressure, vacuum dehydration, reach the effect of the water in quick slag-water slurry, realize pulp water separation rapidly and efficiently.
Further, the filtering layer supporting part is an entirety or is made up of polylith.Piecemeal can be carried out according to filter tank size,
The hot water pool structure does corresponding Aided design, ensures that the entirety in the region alternative and filter tank of the hot-tub scarfing cinder connects
The general character.
Further, the filtering layer supporting part is flase floor.
Further, the filtering layer supporting part is the steel plate for uniformly offering water hole.
The filtering layer supporting part should have some strength, support the weight of top slag-water slurry and the multistage filtering layer,
Ensure the connectedness of the multistage filtering layer and the hot-tub again.
Further, the aperture of the filtering layer supporting part water hole is less than multistage filtering layer bottom maximum particle size particle diameter of filter medium, protects
Demonstrate,prove the low turbidity of slag drainage in the hot-tub of bottom.
The beneficial effects of the utility model are：Reduce pulp water and filter full-range fume emission, improve operation environment,
Avoid corrosion of the flue gas to piping lane equipment and pipeline；Receipts hydraulic pipeline can be greatly simplified again, and rhythm of production is accelerated, and realizes pulp water mistake
Efficient, the energy-saving operation of filter.

Embodiment
Embodiment of the present utility model is illustrated by particular specific embodiment below, those skilled in the art can be by this
Content disclosed by specification understands other advantages and effect of the present utility model easily.
Embodiment
Fig. 1 is the structural representation that the utility model is applied to blast furnace slag processing system, a kind of filter of the present utility model
The filter tank that layer connects with hot-tub, including filter tank and the filtering layer supporting part 2 and multistage filtering layer 1 that are arranged in filter tank, multistage filtering layer 1
The top of filtering layer supporting part 2 is supported on, the hot-tub 3 formed below of filtering layer supporting part 2, the multistage top of filtering layer 1 is pulp water mixed zone, filter
Layer supporting part 2 has water hole, and hot-tub 3 connects through water hole with multistage filtering layer 1.Connecting pipe is arranged in hot-tub 3
In low turbidity clear water, elevator pump 4 is directly connected to hot-tub 3 by pipeline.During work, certain negative pressure is formed in filter tank.
In blast furnace slag processing system, crane is additionally provided with above filter tank and grabs the grab bucket of slag, elevator pump 4 passes through pipeline
Hot water after filtering is promoted to cooling tower.
The utility model, multistage filtering layer 1, filtering layer supporting part 2, hot-tub 3 are arranged in same filter tank, i.e. pulp water in filter tank
Filter water is in same connection container (filter tank) in mixture, multistage filtering layer 1 and bottom hot-tub 3.In addition elevator pump 4 and heat
Pond 3 is directly connected to by pipeline, and certain negative pressure is formed in filter tank, vacuum dehydration, reaches the separation slag realized rapidly and efficiently
