Abstract
The utility model discloses a mineral roaster batching system which comprises a plurality of raw material storage bays, a weighing device and a material mixing unit. The raw material storage bays and the material mixing unit are respectively provided with a feed port and a discharge port, the discharge ports of the raw material storage bays are directly connected with the feed port of the material mixing unit or through a pipeline or material conveying mechanism, the material mixing unit is a material mixing bay, a double spiral agitator is arranged in the material mixing bay, and the weighing device is an electronic hopper scale arranged on the material mixing bay. By the aid of the electronic hopper scale arranged on the material mixing bay, existing idiomatic dynamic weighing by a belt scale in the material conveying process is changed into static weighing by the material mixing bay, so that the shortcomings of large errors, batching control lag and the like of dynamic weighing can be avoided, and batching and weighing are more accurate. Besides, as a material conveying space is increased and material mixing effects are better, batching capacity can be greatly improved.
Description
Technical field
The utility model relates to the batching of roasting mineral, more particularly relates to a kind of mineral calcining furnace feed proportioning system.
Background technology
In industries such as iron and steel, building materials, smeltings, usually need plurality of raw materials (such as coke, concrete, sintering deposit etc.) is mixed formation a kind of new raw material to be processed or product in specific proportions, this hybrid technique is called batching.According to technology general knowledge, more accurate to the independent weighing of various raw materials, the effect of batching obviously can be better.At present, the larger feed proportioning system of raw material materials amount adopts following technical scheme to realize usually: the material in each raw material feed bin by the valve that is located at bin bottom unload be put into separately conveyer belt that the processing machine feeding mouth links to each other on, raw material is sent to the process of processing machine feeding mouth from conveyer belt, claims raw material is weighed by the belt that is located on the conveyer belt; By start and stop and the transfer rate of controlling each conveyer belt, the material in each raw material feed bin can be transported to processing machine in required weight or ratio and carry out mix.
Adopt above-mentioned proportion scheme, may have following weak point: (1) adopts Dynamic Weighting, and easily produce weighting error also and then affect proportioning accuracy and the batching effect, and, easily produce batching control hysteresis; (2) because the processing machine capacity is usually all smaller, the production capacity that causes preparing burden is lower, and mixing of materials is inhomogeneous; (3) be required to be that every kind of raw material arranges independent conveyer belt and belt claims, high expensive, and, limited by the place, production scene, production scene utilization of area rate is low.
The utility model content
The purpose of this utility model namely is to provide a kind of simple in structure, the batching weighing error is little, mixing of materials is effective mineral calcining furnace feed proportioning system.
The technical scheme of the utility model mineral calcining furnace feed proportioning system is: mainly include several raw material feed bins, weighing device and a mixing of materials unit; Described each raw material feed bin and mixing of materials unit are respectively equipped with charging aperture and discharging opening; Its special feature is: the discharging opening of described raw material feed bin directly links to each other with the charging aperture of described mixing of materials unit, perhaps, links to each other by pipeline or material transport mechanism; Described mixing of materials unit is blending bunker, is provided with double spiral agitator in this blending bunker; Described weighing device is that the electronic type hopper that is located at described blending bunker claims.
When the utility model mineral calcining furnace feed proportioning system was used for electrolytic manganese dioxide reduction roasting batching, described raw material feed bin only had two: be respectively ore storage bin and coal bunker; At this moment, can will link to each other by material conveyor belt between the charging aperture of described ore storage bin discharging opening and described blending bunker; The discharging opening of described coal bunker is located at the charging aperture top of described blending bunker, links to each other with blending bunker by the feed by-pass valve control.
Characteristics and the advantage of the utility model mineral calcining furnace feed proportioning system:
(1) by adopting blending bunker to substitute traditional processing machine, can greatly increase the batch mixing space; Be equipped with the employing double spiral agitator, can guarantee the mixing of materials effect, thereby the batching production capacity is also promoted greatly;
(2) by being set at blending bunker, the electronic type hopper claims, the weighing results that various materials is added front and back subtracts each other the component raw material weight that can obtain to add, be static weighing thereby change existing Dynamic Weighting, avoided the Dynamic Weighting error, batching weighing is more accurate, and batching control is also more timely;
(3) when the raw material feed bin only has two, whole feed proportioning system can only arrange a material conveyor belt, and system building cost and operation cost are lower.
(4) control is simple, is convenient to realize automatic proportioning.

The specific embodiment
Below in conjunction with accompanying drawing the utility model mineral calcining furnace feed proportioning system is further described.
Fig. 1 is the composition schematic diagram of common mineral calcining furnace feed proportioning system.As shown in the figure, material in each raw material feed bin 1 unloads on the material conveyor belt 2 that is put into separately by the valve 4 that is located at bin bottom, raw material is sent to the process of processing machine 3 from material conveyor belt 2, claims 5 pairs of raw materials to weigh by the belt that is located on the material conveyor belt 2; By start and stop and the transfer rate of controlling each material conveyor belt 2, the material in each raw material feed bin 1 can be transported to processing machine 3 in required weight or ratio and carry out mix.
Fig. 2 is the composition schematic diagram that the utility model mineral calcining furnace feed proportioning system is applied to an embodiment in electrolytic manganese dioxide reduction roasting when batching.When being used for electrolytic manganese dioxide reduction roasting batching, the raw material feed bin of using has two, as shown in Figure 2, is respectively coal bunker 6 and ore storage bin 7; The technical solution adopted in the utility model is: adopt blending bunker 8 to substitute the narrow and small processing machine of the usual stirring space that adopts in the prior aries as the mixing of materials unit; Send into blending bunker 8 from ore storage bin 7 discharging openings mineral aggregate out by material conveyor belt 2; The discharging opening of coal bunker 6 being located at the charging aperture top of blending bunker 8, by the material deadweight coal being sent into blending bunker 8, therefore, need not be the ad hoc material conveyor belt of discharging of coal bunker 6 again; At blending bunker 8 the electronic type hopper is set and claims 9, be used for the material of sending blending bunker 8 to is carried out static weighing, be discharged into each component raw material weight that the front and back weight difference of blending bunker 8 can obtain to add according to material.For strengthening compounding effect, in blending bunker 8, be provided with double spiral agitator 10, this double spiral agitator 10 is provided with each agitating auger of length.
The utility model mineral calcining furnace feed proportioning system directly links to each other with the charging aperture of described mixing of materials unit according to the discharging opening of place reality with each raw material feed bin when being applied to other field, and perhaps, linking to each other by pipeline or material transport mechanism gets final product.
