Abstract
The utility model discloses a wet ball mill with a feeding groove, which comprises a wet ball mill and mainly a feeding groove. A screw conveyor is arranged at the bottom of the feeding groove, the rear end of the screw conveyor extended from the feeding groove is inserted into a feeding port of the wet ball mill, and two side surfaces of the feeding groove are shaped into inverted triangles. The utility model is simple in structure, low in manufacturing costs, scientific, reasonable and capable of manufacturing dense and viscous white mud with bad liquidity into evenly dispersed seawater white slurry by adding some seawater and enabling the white slurry to be served as a desulfurizer which can replace originally used pulverized lime. A slurry producing system utilizing one wet ball mill with the feeding groove can be applied to the flue gas desulfurization of small fuel electric plant boilers or of boilers and kilns of industrial and mining enterprises which require desulfurization of a small amount of white mud.
Description
(1) technical field
The utility model relates to a kind of wet ball mill, and particularly a kind of ammonia-soda process soda ash that utilizes is produced the wet ball mill of bringing hopper into that white clay after the waste residue press filtration and seawater are produced seawater soda-residue emulsion.
(2) background technology
Waste residue (white clay) after ammonia-soda process soda ash production press filtration amount is big, and is all discarded or store up as waste residue in countries in the world, causes public hazards, and its processing is the difficult problem that countries in the world face jointly.Chinese patent application number is 97121098.5 disclosed " two-way treatment process of pernicious gas in a kind of Sodium Carbonate Plant white clay and the flue gas ", and white clay adds seawater and is deployed into seawater soda-residue emulsion and can removes sulfur dioxide in the boiler smoke effectively.White clay is the suspension in the waste liquid that produces of soda ash production process, the suspension average grain diameter is 20 μ m only, clarify through waste liquid, the suspension content that its precipitation is obtained by press filtration, dehydration is 33～37% filter cake, white clay fragment surface is stiff, inner thickness, mobile poor, it will being added seawater, to make the scattered newborn body of suspension very difficult, in the laboratory, adopt seawater and white clay are added the container stirring, or mix the whole bag of tricks such as extruding in the adding screw(-type) feeder, all do not reach the newborn requirement of even system.Outsourcing rolling bearing wet ball mill can be produced even newborn body, its conventional feeding manner is to establish fixed flow to insert the wet ball mill feeding mouth that rotates, and material enters wet ball mill from flowing suitable for reading the entering of son by gravity rolling, but mobile poor because of the white clay piece, can't enter according to a conventional method.Current pressing for can add the white clay fragment seawater and be deployed into the newborn device of the homodisperse system of suspension, and the industrial production that provides seawater soda-residue emulsion to remove sulfur dioxide in boiler and the kiln gas is used.There is not white clay to add the report of the commercial plant of seawater system breast at home and abroad as yet.
(3) summary of the invention
The purpose of this utility model is exactly that a kind of wet ball mill of bringing hopper into is provided in order to address the above problem, and adopts this device can force white clay to enter in the wet ball mill, white clay can be added seawater and make the scattered even newborn body of suspension.
The purpose of this utility model is realized by following technical scheme: it comprises wet ball mill, it is characterized in that also including hopper, the feed chute bottom is provided with conveying worm, stretch out in the feeding mouth that inserts wet ball mill from feed chute the rear end of conveying worm, and the two sides of feed chute are del.
The helical blade of conveying worm is the displacement variable-diameter structure, makes the interior white clay of feed chute evenly give the wet type ball mill reinforced, avoids occurring in the feed chute phenomenon of dead angle, local blanking.
At the middle part of feed chute the low-rotate speed spiral is set, can prevents white clay arch camber in feed chute.Top two sides of feed chute are provided with the sea intake pipe.Seawater fully contacts, mixes with white clay from two side-entry grooves, improves the flowability of white clay, can prevent that also white clay from adhering to cell wall.
The utility model has the advantages that simple in structure, scientific and reasonable, can be with closely knit, thickness, the white clay of mobile difference adds seawater and makes homodisperse seawater soda-residue emulsion, can make the pulverized limestone that fume desulfurizing agent substitutes former use.

Fig. 1 structural representation of the present utility model;
Fig. 2 is Figure 1A-A cutaway view;
Fig. 3 is a workflow diagram of the present utility model.
(5) specific embodiment
As shown in the figure, feed chute 1 is del, and two sides and horizontal sextant angle are 60 °, and its capacity is the dipper capacity of two loading machines, and the top is uncovered is convenient to material feeding.Conveying worm 1.1 is arranged at feed chute 1 bottom, and conveying worm 1.1 can be the speed governing conveying worm of band frequency conversion, according to the white clay amount that desulfurization need be used, adjusts rotating speed and satisfies use.Wet ball mill 2 is outsourcing rolling bearing ball mill, stretches out conveying worm 1.1 rear ends of feed chute to insert from the feeding mouth 2.1 of wet ball mill 2, and helical blade 1.2 is inserted to wet ball mill 2 ante-chambers.Because conveying worm 1.1 is subjected to charge level big, as being provided with routinely, in the feed chute 1 local blanking can appear, and feed chute 1 effective usable floor area is diminished.For this reason, helical blade 1.2 structural designs with conveying worm 1.1 are displacement reducing form.Helical blade 1.2 diameters of its conveying worm 1.1 ends are the twice of initiating terminal diameter, its pitch be front and back two helical blade diameters and 1/2nd.Two sides are provided with sea intake pipe 1.4,1.5 on the top of feed chute 1.1.Add the low-rotate speed spiral 1.3 of band frequency conversion adjustable speed at feed chute 1 middle part, rotating speed works white clay, the help blanking effect stirred less than 30 rev/mins.
The accompanying drawings workflow:
Loading machine adds feed chute 1 with white clay, seawater is regulated through sea intake pipe 1.4,1.5 and is added simultaneously, white clay and seawater are sent into the conveying worm 1.1 of bottom land through low-rotate speed spiral 1.3, the rotation of conveying worm 1.1 is forced white clay and sea water mixing thing equably by helical blade 1.2 and is delivered in the feeding mouth 2.1, makes seawater soda-residue emulsion through wet ball mill 2 ball millings.Regulate the import volume of white clay and seawater, can be made into and contain the scattered uniform sea soda-residue emulsion of suspension.According to on-the-spot needs, during use, be equipped with slurry tank 3, be contained in slush pump 4 and hydrocyclone 5 under the liquid in the slurry tank 3.This seawater soda-residue emulsion can be sent into slurry tank 3, slush pump 4 pressurizations are sent into hydrocyclone 5 by pipeline under liquid, and under action of centrifugal force, the tiny white clay sand that concentrates on hydrocyclone 5 bottoms can be back in the hopper 1, continuation is improved the utilization rate of white clay by ball milling.Seawater soda-residue emulsion is delivered to desulphurization system from hydrocyclone 5 tops through pipeline uniformly, is diluted to desired concn with seawater and uses.This device of designing and developing, utilize the 670t/h boiler of power plant 225MW generating set to carry out ten days by a definite date industrial tests, the desulfurizing agent pulverized limestone of the alternative former use of seawater soda-residue emulsion that this device provides, add seawater at liquid storage tank and be diluted to suspension content 2 ‰, enter former desulfurizing tower, the every requirement of desulfurization is all up to standard.Can provide small power station's boiler as pulping system or need the industrial and mining enterprises' boiler of a small amount of white clay desulfurization and the flue gas desulfurization of kiln to use with this device.
