Description
Technical field
The utility model relates to the delivery system of the quantitative rotovalve of a kind of new continuous.
Background technology
Present domestic continuous and quantitative delivery system mainly contains the delivery system of following two kinds of forms: 1) single jar of continuous injection system of timing; It needs according to customer requirement; Set single jar volume; In a period of time, realize carrying continuously, the control valve opening at the bottom of operational throughput is arranged on jar through adjusting is realized the control of material amount.This delivery system can be carried under the situation that big back pressure is arranged; Normal delivery pressure is in 0.4MPa; Like submergence injection system in metallurgy, the steel industry stove, but, be prone to cause the insufficient or oversaturation of reaction of reacting furnace owing to pass through factors such as the error of valve opening regulating control mass transport amount is big, blanking amount instability; Need actual reaction condition in the real stove of the continuous stoning of on-the-spot operating personal, the working strength of workers that had so both caused the waste of raw material also to increase; 2) rotovalve delivery system; It can only be used for environment under low pressure under conveying; Usually delivery pressure is no more than 60Kpa; And because of the rotovalve turning cylinder is horizontal, rotovalve blade filling rate in rotation process is unstable, and this system can only make and be applicable in the not high operating mode of low pressure and operational throughput control accuracy thus.
Summary of the invention
In view of the defective that above-mentioned prior art exists, the utility model purpose is the delivery system that proposes the quantitative rotovalve of a kind of new continuous in order to overcome above-mentioned shortcoming, to satisfy conveying continuously under specific operation, pressure-bearing conveying and measuring fixed amount.
The technical scheme of the utility model is: the delivery system of the quantitative rotovalve of a kind of new continuous, it comprises: the rewinding jar, be positioned at rewinding jar below the winding-up jar, be positioned at rewinding jar top storage tank, be arranged on winding-up pot bottom and the frequency conversion feeder that is connected with delivery duct, be arranged on LOAD CELLS in the winding-up jar, control the single chip circuit of frequency conversion feeder and be arranged on the rewinding jar or the fluidisation gas circuit of winding-up jar according to the signal of LOAD CELLS.
On the basis of technique scheme, further comprise attached technical scheme:
Said rewinding jar jar all is provided with a pneumatic valve at inlet with winding-up, the motor that the frequency conversion feeder comprises frequency changer circuit at least, driven by frequency changer circuit, by the feed winding-up pump of driven by motor.
Said rewinding jar is continuous feed, and the winding-up jar is for being interrupted the continuous discharging of charging.
The utility model is used under the pressure-bearing environment, solving continuous, the accurate quantification conveying of material.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further described:
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Embodiment: with reference to shown in Figure 1; The utility model provides the specific embodiment of the delivery system of the quantitative rotovalve of a kind of new continuous, it comprises rewinding jar 10, be positioned at the winding-up jar 20 of rewinding jar 10 belows, be positioned at rewinding jar 10 tops storage tank 30, be arranged on winding-up jar 20 bottoms and a frequency conversion feeder 40 that is connected with delivery duct (not shown), be arranged on LOAD CELLS 60 in the winding-up jars 20, control the single chip circuit 50 of frequency conversion feeder 40 and be arranged on rewinding jar 10 or the fluidisation gas circuit of winding-up jars 20 according to the signal of LOAD CELLS 60.Wherein rewinding jar 10 is connected in series arrangement up and down with winding-up jar 20; And rewinding jar 10 all is provided with a pneumatic valve at inlet with winding-up jar 20; Winding-up jar 20 is used for to frequency conversion feeder 40 constant material amount being provided, and the fluidisation gas circuit is used for that material is carried out fluidisation in jar and is convenient to carry.The motor that frequency conversion feeder 40 comprises frequency changer circuit at least, driven by frequency changer circuit, by the feed winding-up pump of driven by motor.Frequency conversion feeder 40 is sent into material in the delivery duct through pressurized air, is delivered to target thus.Single chip circuit 50 is also controlled closing of pneumatic valve.
High charge level is housed on the rewinding jar 10 reports to the police, and winding-up jar 20 is provided with low material level warning, is convenient to monitor weight of material.In rotation feed winding-up pump operation process, the phase will write down the weight of material in 2 winding-ups jar to the control system of single chip circuit 50 weekly: jar fills up back (canful) record for the first time, and (slack tank) immediate record second time before the filler again.Between twice weight measurement, control system will write down the revolution of motor.Deduct slack tank weight by canful weight and draw convey materials quantity,, obtain " feeder calibration factor ", be the mass transport amount of revolution again divided by the feeder revolution same period.Control system is set feeder speed with revolution mass transport amount, with the desirable injecting velocity that obtains to set.
In the material winding-up process, winding-up jar 20 is with pressure, and rewinding jar 10 is periodically given winding-up jar 20 additional materials through winding-up jar 20 and the pneumatic valve between the blanking scraper-trough conveyer in hyperbaric environment.And pneumatic valve receives the control of single chip circuit 50, and during jar 20 additional materials of jetting, material can be carried continuously like this, and rewinding jar 10 is that continuous feed, winding-up jar 20 are for being interrupted the continuous discharging of charging thus.
The utility model is used under the pressure-bearing environment, solving continuous, the accurate quantification conveying of material.
Certainly the foregoing description only is the technical conceive and the characteristics of explanation the utility model, and its purpose is to let the people who is familiar with this technology can understand content of the utility model and enforcement according to this, can not limit the protection domain of the utility model with this.All equivalent transformation or modifications of doing according to the spirit of the utility model main technical schemes all should be encompassed within the protection domain of the utility model.
