Description
Technical field
The utility model relates to a kind of measurement mixing unit, the continuous weight-loss metering mixing device of particularly a kind of liquid.
Background technology
In the middle of the plastic processing industry, the liquid charging stock of various viscosity occupies a very big share, so the metering of liquid charging stock interpolation also is a very important technical process.Because the intensification of market competition and the further rise of material price, improving the quality of products being devoted in each production commercial city, reduces production costs, and reduces loss.Therefore measurement charging device becomes imperative equipment in manufacturer's production technology.In the past in the plastic processing industry, domestic majority enterprise in liquid charging stock metering adding technology still applying volume formula metering device carry out raw material and add and produce, yet there is following defective in the volume type metering device:
(1) pressure and temperature of liquid charging stock environment is had relatively high expectations,,, can the precision generation of producing be had a strong impact in case the pressure and temperature of raw material environment changes because liquid volume receives environmental pressure and Influence of Temperature is bigger.
(2) the volume type metering device needs experienced professional output as required to estimate input value setting through input value control measuring pump the time; And an experienced professional can cultivate out in the short time; If not experienced personnel; Can not grasp the accurate values input in short time, in case error will have a strong impact on the product precision.
(3) the volume type metering device is not high for the feedback of production precision; Must the dependence experience on frequency converter, providing a control numerical value sets; Must proofread and correct adjustment numerical value over time again and guarantee measuring accuracy, otherwise after after a while, possibly make precision inaccurate because of error.
(4) because liquid charging stock is subject to environmental pressure and Influence of Temperature, add that the degree of feedback of volume type metering device is not high, so before operation or when changing ratio, must carry out manual correction according to the data on the frequency converter and come control accuracy.Required prescription and process data difficulty are stored in the frequency converter; So when various data such as needs replacing prescription and output, have to again data imported and corrected, need operation manually by the professional; Consumed time is long, influences production efficiency.
(5) because the volume type metering device has certain requirement to raw material environmental pressure temperature etc.; The grasp of prescription, numerical value, precision etc. all needs experienced personnel manually to control; Because the frequency converter degree of feedback is not high; Need have the people to look after on the production line side at any time, so quite high to the control requirement of entire production process, the consumption worker consumes power.
(6) liquid charging stock is to the having relatively high expectations of self temperature, and some raw material must could guarantee normal the conveying reaching under the certain temperature condition, and general metering device does not have lagging facility, can not satisfy the raw material production requirement of some specific (special) requirements.
The utility model content
The utility model technical problem to be solved provides the continuous weight-loss metering mixing device of a kind of liquid, and it adopts the mode of weighing unit with gravimetric, calculates the interpolation quantity of raw material through the weight of measuring the raw material minimizing.
For solveing the technical problem; The utility model provides a kind of liquid continuous weight-loss metering mixing device, it is characterized in that, it comprises measuring pump, metering feed bin, metering feed bin feeding mouth, weighing unit, motor and frame; Weighing unit is fixed on the frame and carries whole metering feed bin; Measuring pump is connected through flexible pipe with the metering feed bin, and metering feed bin feeding mouth is above the metering feed bin, and motor is installed on the frame and with measuring pump, weighing unit and electrically connects.
Preferably; Said metering feed bin comprises metering feed bin heat-insulation layer, metering feed bin heat-insulation layer thermal insulation medium inlet and the outlet of metering feed bin heat-insulation layer thermal insulation medium; The periphery of metering feed bin is encased by metering feed bin heat-insulation layer; Metering feed bin heat-insulation layer thermal insulation medium inlet is at a side of metering feed bin, and the outlet of metering feed bin heat-insulation layer thermal insulation medium is in the bottom of metering feed bin; Measuring pump comprises the measuring pump heat-insulation layer, and the measuring pump heat-insulation layer encases the pipeline of measuring pump.
Preferably, said metering feed bin is shaped as tubular.
The positive progressive effect of the utility model is: the utility model carries out the accurate interpolation of raw material through the weight-loss metering feeding, can increase the yield rate of product, receives environmental pressure and Influence of Temperature little.In addition, the utility model adopts the gravimetric mode, and therefore metering receives environmental pressure and Influence of Temperature is little, and can satisfy high-precision raw material feeding requirement, and measuring accuracy can reach ± and 0.5%.The utility model can increase heat-insulation layer according to the requirement of client's raw material production outside the metering feed bin, make some raw materials with specific (special) requirements guarantee under the uniform temperature and then to carry out Weighing more exactly.
Description of drawings
Fig. 1 is the perspective view of the continuous weight-loss metering mixing device of the utility model liquid.
The specific embodiment
Lift a preferred embodiment below, and combine accompanying drawing to come the clearer the utility model of intactly explaining.
As shown in Figure 1, the continuous weight-loss metering mixing device of the utility model liquid comprises measuring pump 10, metering feed bin 11, metering feed bin feeding mouth 12, weighing unit 20, motor 40 and frame 50.Weighing unit 20 is fixed on the frame 50 and carries whole metering feed bin 11.Measuring pump 10 is connected through flexible pipe with metering feed bin 11, metering feed bin feeding mouth 12 measure feed bin 11 above, motor 40 be installed on the frame 50 and with measuring pump 10, weighing unit 20 electric connections.
The continuous weight-loss metering mixing device of the utility model liquid is when producing; Liquid charging stock gets into metering feed bin 11 through measuring chute feeding mouth 12 under the control of valve; Carry out raw material output by measuring pump 10; 20 pairs of whole metering feed bins 11 of weighing unit are weighed, and calculate feed rate through measuring the weight that raw material reduces in the metering feed bin 11, and require adjustment output and feed rate according to client's output.Whole equipment provides driving by motor 40, is convenient to client's mobile device and installs and fixes to the position that needs.
