The powder intelligent bulk bin metering device is characterized in that a discharging switch flow regulating valve is arranged on the lower part of the bulk bin; a rotary semicircular valve body is arranged in the discharging switch flow regulating valve; a fine flow opening is formed on a cambered surface of the valve body; and the valve body is driven by an air cylinder to rotate. The powder intelligent bulk bin metering device has the advantages that during end discharging, the openness of a regulating valve is reduced gradually, and the fine flow opening is employed; an intelligent micro computer is employed for weight-losing measurement, superposition feeding detection and sampling are employed, feeding static pre-measurement and terminal decrement static measurement are employed, and measurement accuracy is high than that of an electronic vehicle scale, a belt scale and a spiral scale; and the powder intelligent bulk bin metering device is large in one-time measurement weight, high in filling speed, low in time consumption, high in environment-friendly performance, dust pollution-free, and reliable and stable in totally-closed operation, the measurement accuracy is not influenced by dust removal, the efficiency of a management platform is improved, and tank car tare dissension is avoided.
Description
Technical field
The utility model relates to a kind of powder material can and uses metering outfit, is applicable to the high precision of powder material, the metering of maximizing, and the powder material sealing is strong, precise control, good stability, especially a kind of novel environment friendly equipment of quick filling measurement of powder tank car.
Background technology
High speed development along with cement industry, merchant's mixing cement; Development bulk cement is the important economy, the measure of skill wood that economize on resources, protect environment, is of great significance to promoting manufacture of cement, circulation, the use field style of economic increase to be changed to economizing type by extensive style.Bulk cement will be banned sack cement gradually at cement industry, become an important step of cement production process.Improve the measuring accuracy of cement bulk, reduce Cement Production, carrying cost, improve operative employee's work situation, it directly has influence on output, quality and goodwill, is the target that cement production enterprise is pursued.
Metering, the entrucking of exhibition bulk cement in manufacture of cement, circulation, use field, the portable bulk vehicle can tank car of most employings, the metering of gas car weighing apparatus is still comparatively backward.Some bulk cement metering outfits have preferably appearred in the market; Like the patent No. is 01267146.0 aproll mud weigher; The patent No. is 200420058255.5 powder material weighers; The patent No. is 08709730 prose style free from parallelism measuring chute, and the measuring accuracy of these bulk cement equipment improves a lot.But, still can not satisfy the requirement of quick can of the maximization powder tank car of high precision, high-speed, low dust discharge.
Summary of the invention
The purpose of the utility model is to overcome above deficiency, provides a kind of powder intelligence storehouse in bulk weigher to remedy the deficiency of prior art, and this WT-MSR has the measuring accuracy height; The powder material sealing is strong; Precise control, good stability helps powder material maximization metering.Be applicable to the high-precision measuring of powder material; Especially a kind of novel environment friendly equipment of quick can of powder tank car; Have superior performance, adapt to wide, environmental protection and energy saving, characteristics such as automaticity height; Be that modern big-and-middle-sized cement mill, Steam Ship Wharf are for improving automaticity, the preferred unit that reduces production costs.
The utility model for realizing the technical scheme that purpose adopts is: a kind of powder intelligence storehouse in bulk WT-MSR; Comprise storehouse 2 in bulk and sensor 1 and Weighing system and control system; It is characterized in that: be arranged with discharging switch flow control valve 5 in storehouse 2 in bulk; The semicircle valve body 14 that rotation is arranged in the discharging switch flow control valve 5 has thread amount mouth 15 on valve body 14 cambered surfaces, valve body 14 is by cylinder 16 driven in rotation.
Described a kind of powder intelligence storehouse in bulk WT-MSR, it is characterized in that: described cylinder 16 is three cylinders, its three strokes make valve body 14 be in the state of standard-sized sheet, full cut-off or thread amount.
Described a kind of powder intelligence storehouse in bulk WT-MSR is characterized in that: be provided with fly-ash separator 7, be connected on discharging switch flow control valve 5 after.
The good effect of the utility model is: the discharging of terminal hour section is adopted and is turned down adjustable valve aperture and thread amount mouth step by step, and the little metering in terminal does not result in blockage again, measuring accuracy extra-high-speed (reaching 0.1%), qualification rate nearly 100%.Adopt storehouse ballast power discharging, initial loading material filling position high pressure is big, and discharging speed is fast; Dress material filling position, terminal low-pressure is little, and discharging speed is slow, and measuring accuracy is high.The intelligent microcomputer weight-loss metering adopts the stack charging to detect, sample, the static expectation amount of charging, and terminal decrement static weighing, measuring accuracy is higher than electronic vehicle weighing apparatus, belt conveyer scale, helix balance.Powder intelligence storehouse in bulk weigher metering filling, it is big once to calculate the weight, and filling speed is fast, weak point consuming time.The intelligent microcomputer weight-loss metering, the powder material of collecting during the tinning car is got back in the tank car, good environmental protection, dedusting does not influence measuring accuracy.Powder intelligence storehouse in bulk weigher, sensor is located at the bulking system top, and no dust pollution is totally-enclosed reliable, stable, operative employee's work situation clean hygiene.Powder intelligence storehouse in bulk weigher, intelligent high, be provided with long-range middle control (DCS) operational mode interface, improved management platform, stopped the dispute of tank car tare weight.

Embodiment
Embodiment: the utility model course of work is: during the WT-MSR work of powder intelligence storehouse in bulk; Automatic control cabinet 12 is opened feed rate variable valve 4; Powder material gets in the storehouse 2 in bulk, and material carries out detection of dynamic, sampling in 8 pairs of storehouses 2 in bulk of intelligent weighing indicator, when weight of material reaches the higher limit of setting in the storehouse 2 in bulk; Close feed rate variable valve 4, stop feeding.Intelligent weighing indicator 8 carries out Static Detection simultaneously, discharging is waited in the sampling metering.After tank car 20 butt joints put in place, automatic control cabinet 12 was opened discharging switch flow control valve 5 (this moment, valve body 14 was in full-gear) through control cylinder 16, and 8 pairs of storehouses in bulk of intelligent weighing indicator, 2 materials carry out decrement detection of dynamic, sampling; When weight of material reaches 99.8% value of setting in the storehouse 2 in bulk; The valve body 14 controlled apertures (semicircular valve body 14 rotations) that reduce step by step; Up to the state that is in the thread amount, this moment, powder can only pass through from thread amount mouth 15, and flow is very little; When weight of material reaches the value of setting in the storehouse in bulk, valve body 14 controlled complete shut-downs (thread amount mouth 15 is all closed).The discharging action is accomplished, and accomplishes Static Detection, sampling metering.
21 is exhausr port, and 22 is the powder material import.
In the discharging switch flow control valve 5 valve body 14 is arranged, the thread amount mouth 15 on the flow regulation valve body 14, the sectional area of the cement-packing plant ash discharge mouth on the sectional area of thread amount mouth 15 and the present market is suitable, and three cylinders 16 are arranged on the discharging flow variable valve 5.
The key of the utility model is: when the critical conditions that valve cuts out, artificial Control Flow slows down blanking velocity, thereby the error in dipping that the reasons such as hysteresis of total system are caused reduces to minimum.
