Abstract
The utility model discloses an ore fines feed bin, which comprises a steel conical bin body, wherein the inner wall of the bin body is a heavy anticorrosion nano ceramic coating. According to the ore fines feed bin, a bin wall vibrator which is commonly used in bins, consumes power and produces noises is eliminated, thereby a stable blanking of materials can be maintained, the production efficiency can be effectively improved, and the ore fines feed bin is particularly applicable for the ingredients of the moist ore fines in smelting plants, chemical plants and building materials factories.
Description
Technical field
The utility model relates to the fine ore feed bin that a kind of smelting, chemical industry, Building Materials Factory are used.
Technical background
The raw material concentrate of coloured smelting factory, steel plant generally is to be provided by the ore dressing plant, removes main metal compound beyond the region of objective existence, also contains some other cmpds, as: sulfide; The about 7-16% of moisture when moisture is high, has certain bonded assembly performance, this powder characteristics; In material conveying process, a lot of difficulties have been brought, particularly in the discharging in storehouse; Because existing feed bin is generally processed by steel plate, and in the fine ore because the chemical reaction of sulphur, the reasons such as high pressure after the bonding of moisture, friction and feed bin are piled up; Make batch bin discharging smoothly, had a strong impact on the stable of continuous flow procedure process load, and the quality of automatic blending.For example, the discharging simultaneously of 6 concentrate stores of certain factory often has 2-3 Bin Card to live out not material, brings the frequent adjustment of flow, has influenced output, quality and energy consumption.
People have taked some measure attempts to eliminate the phenomenon that blanking is obstructed for this reason, such as the tapering that adds big material bin, think that tapering should be more than 75 degree; The warehouse discharging mouth adds the release storehouse, to slow down the high material pressure of piling up in the feed bin; Install the rapping machine on the outer wall of storehouse additional, storehouse inwall and binder are thrown off as far as possible, be convenient to blanking; Add the spiral stirring unit in the storehouse, to destroy the arch bridge that rises in the storehouse; Add logical compressed air tube in the storehouse, irregularly open material knot in the loosening storehouse of pressurized air (not moisture); Add part stainless steel sheet etc. in the storehouse.But these measures alleviate putty problem in the feed bin to a certain extent to some extent, but still can not realize stablizing blanking.
The utility model content
The purpose of the utility model is to provide a kind of no rapping, can keep stablizing the fine ore feed bin of blanking.
This fine ore feed bin that the utility model provides comprises the conical warehouse of steel, and the inwall of this warehouse is the heavy-duty anticorrosive nano cramic coat.
The tapering of said warehouse is at least 60 degree.
The utility model has been owing to covered the heavy-duty anticorrosive nano cramic coat at the inwall of warehouse, and its friction coefficient is near 0.04, by the downward tangential force of 0.05 its inwall than inwall friction force up to more than 10 times.And 60 ° with top rade, all at this order of magnitude, the effect of visible material friction coefficient than 60 degree with big many of the variation of top rade, thereby guaranteeing can have than small inclination under the whole blanking situation, the storehouse just has bigger bin stock amount.The heavy-duty anticorrosive nano cramic coat has with the steel plate binding force strong, wear-resisting, corrosion resistant, smooth surface; The shock-resistant good characteristic that waits; Be applied on the feed bin of balk cargos such as coloured, chemical industry, building materials, in the storehouse blanking stable, compared with prior art the utility model has been cancelled power consumption commonly used on the storehouse and has been produced the bulkhead vibrator of noise; Can save design-calculated bulkhead rapping machine on the steel silo, to these process industry steady production, Charge Mixture Control, energy-saving and cost-reducing great role arranged.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
As can beappreciated from fig. 1 the utility model feed bin warehouse 1 is turbination, is still processed by steel plate, and its inwall has heavy-duty anticorrosive nano cramic coat 2, and the tapering of warehouse can be done little of the a=60 degree.
Inwall adopts its main performance of heavy-duty anticorrosive nano cramic coat to be:
1. have superpower adhesive ability, can directly be coated on the steel plate.Because also be coated on the pump leaf in its practice, so adhesive ability is superpower;
2. antiseptic power is strong, and the ceramic powder of different fineness and epoxy resin form dense coating, corrosion prevention medium osmosis;
3. strong resistance to abrasion, the wear-resistant extra-heavy of the wear resistant filler in the coating is 3-4 times of general abrasion resistant paint, and can thickeies;
4. strong lubricity is equivalent to polytetrafluoroethylene (the minimum coefficient of friction 0.04 of solid);
5. its good flexible can resist the impact of material.
By above characteristic, this coating material can adapt to the various requirement of fine ore bin, wear-resisting, anti-corrosion, antivibration, shock resistance and the friction coefficient spy is little, and stable.
The scantling of structure design of feed bin needs to determine according to purposes.The inclination angle size in inverted cone storehouse: relevant, also relevant with volume, the carrying capacity of technology Calculation with density, shatter value, angle of repose, binder height, width and the contained humidity of concentrate.According to " powder dynam " principle in the storehouse, it should should select wider range for use than the big 15 ° of inclination angles of bin stock angle of repose more than 60 degree.
According to reference to GB GB50077-2003, the contriver adopts the heavy-duty anticorrosive nano cramic coat and the friction force of prior art feed bin inwall employing steel plate to calculate to the utility model feed bin inwall, sees table one; The result shows: sequence number 1,2, the 3 behavior steel silo computational datas in the form, 4,5,6 behaviors adopt the computational data of heavy-duty anticorrosive nano cramic coat, are respectively to 60 ° at inclination angle, 65 °, 70 ° so divide 3 row; Under the inwall that calculates from every row between tangential force and material wall the friction drag comparative result see, under above-mentioned 3 kinds of inclination angle situation, for pure steel silo; Both are close; Tangential force is slightly larger under the inwall, in case the bulkhead corrosion, friction drag increases; Surpass the following tangential force of inwall, just can not stablize blanking.And for the heavy-duty anticorrosive nano cramic coat,, the following tangential force of inwall is much larger than friction drag, and under 3 kinds of inclination angles, both differ more than 10 times, have guaranteed the prone whole blanking of inwall.
In the construction; Under heavy-duty anticorrosive nano ceramic coating product design; And under the coating products originating firm technical director, should guarantee the construction quality of the clear bottom of storehouse inwall reason and application, the quality of each road working procedure of strict inspection and the bottom discharging equipment in storehouse good is connected cooperation.
