Abstract
The utility model relates to a weighing meter for continuously reducing powder material, which is composed of a weight sensor, a screw conveyer and a pocket feeder and is characterized in that the utility model is composed of a feeding butterfly valve (8), a subtraction weighing bucket (12) which is connected with the lower part of the feeding butterfly valve (8), a respirator (10) and the weight sensor (11) which are arranged on the subtraction weighing bucket (12), the pocket feeder (14) arranged at the outlet position of the subtraction weighing bucket (12), a material collecting bucket (15) arranged below the pocket feeder (14), and a pressure balancing pipe (13) arranged between the material collecting bucket (15) and the subtraction weighing bucket (12). The utility model has high metering accuracy and can not be interfered by environments, and the metering error can be controlled from +0.5 % to-0.5 %.
Description
(1) technical field: the utility model relates to powder decrement measuring apparatus, the continuous decrement Weighing device of especially a kind of powder.Be mainly used in continuous measurement and the functions of physical supply of realizing Stabilized Soil, concrete macrotype set of equipments powder, as the weight metering and the feed of continous way Stabilized Soil, concrete mixing plant cement and flyash.
(2) background technology: existing Stabilized Soil, concrete macrotype set of equipments powder continuous metering device can be divided into two types by the difference of metering system: a kind of employing volumetric metering method.Promptly adopt worm conveyor or star-like dispenser that it is measured and carry, adjust the operational throughput of powder by the rotating speed that changes drive motor.Owing to lack demonstration directly perceived, the setting of its operational throughput and adjustment be trouble very, can only rely on experience and on-the-spot weighing to edit.Powder is subjected to Effect of Environmental, and its density and flow often change, and cause powder accidental overproof bigger, and be difficult for finding, the measuring accuracy instability, the powder waste is serious.The another kind of weight weighing method that adopts.Promptly adopt the spiral electronic scales that powder is measured and carry, below the metering section of worm conveyor, the sensor that weighs is housed, when powder is flowed through metering section, sensor is converted into electric signal with weight and flows to the control microcomputer, microcomputer inside is carried out compose operation and is compared with setting value, and send electric signal and adjust motor speed to adjust the powder operational throughput, making it to conform to setting value, its measuring accuracy is higher.But since factors such as storehouse pressures, environment cause easily the powder obstruction or moment flow increase, cause that easily the chance of powder is overproof, influence the measuring accuracy of powder.
(3) summary of the invention: the purpose of this utility model is intended to improve the deficiency of above-mentioned prior art, and provide a kind of instantaneous delivery and integrated flow of can in good time dynamically showing, it is high and stablize to possess measuring accuracy again, and is not subjected to the continuous decrement Weighing device of powder of environmental factor interference.
The purpose of this utility model can reach by following measure; The continuous decrement Weighing device of powder, form by weight sensor, worm conveyor and rotary pocket feeder, it is characterized in that it is that the subtraction that connects for 8 times by feed butterfly valve 8, with the feed butterfly valve claims to struggle against 12, subtraction claims to struggle against 12 respirators that are provided with 10 and weight sensor 11, subtraction claim to struggle against star-like dispenser 14 that 12 exits install, install star-like dispenser 14 belows holds together hopper 15, holds together barometric pipe 13 compositions that hopper 15 and subtraction claim to struggle against and install between 12.Claim to struggle against at subtraction and can set up title formula feed supplement bucket 7 on 12, claim on the formula feed supplement bucket 7 respirator 5, weight sensor 6 and feed butterfly valve 3 to be installed.Feed butterfly valve 8 and subtraction claim to struggle against and 12 are connected sealing by rubber sleeve 9, and feed butterfly valve 3 is connected sealing with claiming formula feed supplement bucket 7 by rubber sleeve 4.
Compared with the prior art the utility model has following good effect: owing to take this structure to make powder decrement measuring accuracy height, and be not subjected to environmental interference; Set up title formula feed supplement bucket 7 between 12 owing to claim to struggle against, shortened the reinforced time greatly, improved the measuring accuracy concrete structure at feed bin 1 and subtraction, error in dipping can be controlled in ± 0.5% in.
(4) description of drawings: accompanying drawing is the utility model and filler bin 1 and worm conveyor 17 syndeton synoptic diagram
(5) embodiment: embodiment 1, the continuous decrement Weighing device of powder, feed butterfly valve 8 is connected with discharging opening 2 places of filler bin 1, and the below of holding together hopper 15 is connected with worm conveyor 17 by rubber sleeve 16 and gets final product.When microcomputer sends feed instruction, feed butterfly valve 8 is opened, and claiming to struggle against to subtraction 12 adds powder, the microcomputer sampling of weighing simultaneously.When subtraction claims to struggle against powder in 12 when reaching material level, microcomputer sends instruction, closes feed butterfly valve 8.Microcomputer is read the gross weight of hopper and material, and starts star-like dispenser 14 batchings.Along with the outflow of powder, the detected value of LOAD CELLS 11 constantly diminishes, and the changing value in the unit interval is exactly the flow of powder.When powder to during time material level feed butterfly valve 8 open, begin immediately to feed in raw material.In reinforced process, star-like dispenser 14 continues feed with the speed of reinforced eve, arrives up to powder and goes up material level.In the powder course of conveying, microcomputer compares detected value and setting value, and the rotating speed of regulating star-like dispenser 14 is controlled the measuring accuracy of powder, its measuring accuracy height, and be not subjected to environmental interference.
Embodiment 2, claim to struggle against at filler bin 1 and subtraction and set up title formula feed supplement bucket 7 between 12, claim on the formula feed supplement bucket 7 respirator 5 and weight sensor 6 to be installed.Title formula feed supplement bucket 7 is connected with feed butterfly valve 3 by rubber sleeve 4, and feed butterfly valve 3 is connected (this syndeton is seen accompanying drawing) with discharging opening 2 places of filler bin 1.The structure of present embodiment is in order to reduce the influence of powder feed to measuring accuracy, when subtraction claims to struggle against powder in 12 when arriving down material level, with claiming the powder moment in the formula feed supplement bucket 7 to add, has shortened the reinforced time greatly, has improved measuring accuracy.Error in dipping can be controlled in ± 0.5% in.
Claims (3)
1, the continuous decrement Weighing device of powder, form by weight sensor, worm conveyor and rotary pocket feeder, it is characterized in that its be by feed butterfly valve (8), with feed butterfly valve (8) under the subtraction that connects claim the star-like dispenser (14) that respirator (10) that bucket (12), subtraction claim that bucket (12) is provided with and weight sensor (11), subtraction claim the installation of bucket (12) exit, install star-like dispenser (14) below holds together hopper (15), holds together hopper (15) and subtraction and claims the barometric pipe of installing between the bucket (12) (13) composition.
