Abstract
The invention provides an accurate powder conveying device of a mixing plant. The accurate powder conveying device comprises a powder silo, a motor, a speed reducer, a screw conveyer, an electronic scale, a butterfly valve and a powder discharge cylinder; the motor and the speed reducer are arranged on the screw conveyer at the mouth of the power silo; the powder outlet of the screw conveyer is connected to the inlet of the butterfly valve; the outlet of the butterfly valve is connected with the inlet of the powder discharge cylinder; the electronic scale is located under the outlet of the powder discharge cylinder; the powder discharge cylinder is of a tapered chamber structure, the sectional area of the inlet of the tapered chamber structure is greater than the sectional area of the outlet of the tapered chamber structure, an inverted V-shaped baffle plate is arranged in the chamber next to the inlet, and gaps are formed between the two sides of the V-shaped baffle plate and the inner wall of the powder discharge cylinder. On the basis of the previous device, the butterfly valve and the powder discharge cylinder are added so that accurate conveying can be reduced; the accurate powder conveying device is low in modification cost, good in effect and suitable for large-scale popularization and application.
Description
Technical field
The present invention relates to a kind of feedway, specifically a kind of mixing plant powder accurate conveyer device.
Background technology
Mixing plant (building) is in powder metering, mostly adopt conveyor screw metering to carry, control method adopts simple three phase squirrel cage induction motor drive reductor and drive hurricane band mode to carry out mass transport by reductor, threephase asynchronous machine energising operation, carry powder, power-off is out of service, but owing to not adopting the modes such as other brake or resistance braking, cause motor in docking process, because inertia also can turn round, cause powder to continue to carry, and in the exit of powder, setting device does not limit, thereby affect measuring accuracy and cause the waste of powder.
Summary of the invention
In order to address the above problem, the invention provides a kind of mixing plant powder accurate conveyer device, not only solve because inertia causes the problem that delivery precision is inadequate, and effectively prevented the waste of powder.
The present invention is by the following technical solutions: a kind of mixing plant powder accurate conveyer device, comprise filler bin, electrical motor, reductor, conveyor screw and electronic scales, it is characterized in that, also comprise butterfly valve and powder delivery cylinder, described electrical motor and reductor are arranged on the conveyor screw at filler bin Hatch Opening place, the meal outlet place of described conveyor screw connects the import of butterfly valve, and the outlet of butterfly valve connects the entrance of powder delivery cylinder, and described electronic scales is positioned at the below of powder delivery cylinder outlet; Described powder delivery cylinder is cone-shaped cavity structure, and the sectional area of entrance is greater than the sectional area of outlet, is provided with inverted V-arrangement catch near in the cavity of entrance, between the both sides of described V-arrangement catch and powder delivery cylinder inwall, leaves gap.
Further, described conveyor screw is for there being shaft tube type conveyor screw.
Further, described butterfly valve is electric butterfly valve or Pneumatic butterfly valve.
Preferably, the interior angle of V-arrangement catch is 90 degree.
Further, V-arrangement catch is respectively equipped with an inclined-plane near the two ends of flour extraction pipe inwall.
The invention has the beneficial effects as follows:
1, adopt Pneumatic butterfly valve or electric butterfly valve as the by-pass valve control of break-make, take full advantage of butterfly valve and close fast feature, greatly reduced the powder amounts of carrying because of inertia more, ensured to carry the accuracy rate of powder.
2, an affixed powder delivery cylinder in butterfly valve lower end, utilize tapered drum and inverted V-shaped catch, make fall powder can be along catch and the landing of powder delivery cylinder inwall, the outlet of the adding powder delivery cylinder electronic scales of trying one's best, prevent that powder from disperseing in the time directly falling, avoid being blown away or flying away before powder arrives electronic scales, effectively reduce the loss of powder, simultaneously, in the time that motor stops, inverted V-shaped catch can be stored a part of powder, and the little by little powder of omitting when butterfly valve cuts out is held back, and has further ensured the precision of convey materials.
3, on the basis of original device, can realize accurate conveying by installing new parts additional, the cost of repacking is low, effective, is applicable to large-scale promotion and application.
Brief description of the drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is that the master of flour extraction pipe of the present invention looks sectional structure schematic diagram.
In figure: 1 filler bin, 2 electrical motors, 3 reductors, 4 conveyor screws, 5 butterfly valves, 6 powder delivery cylinders, 61 powder delivery cylinder entrances, 62 powder delivery cylinder outlets, 63 V-arrangement catch, 64 inclined-planes, 7 electronic scaless.
Detailed description of the invention
A kind of mixing plant powder accurate conveyer device as depicted in figs. 1 and 2, comprise filler bin 1, electrical motor 2, reductor 3, conveyor screw 4, electronic scales 7, butterfly valve 5 and powder delivery cylinder 6, the powder inlet of described conveyor screw 4 connects the Hatch Opening of filler bin 1, described electrical motor 2 and reductor 3 are arranged on the conveyor screw 4 at filler bin Hatch Opening place, control the running of conveyor screw 4, the meal outlet place of described conveyor screw 4 connects the import of butterfly valve 5, the outlet of butterfly valve 5 connects the entrance of powder delivery cylinder 6, and described electronic scales 7 is positioned at the below of powder delivery cylinder outlet; Described powder delivery cylinder 6 is cone-shaped cavity structure, and the sectional area of powder delivery cylinder entrance 61 is greater than the sectional area of powder delivery cylinder outlet 62, in cavity near powder delivery cylinder entrance 61 places, be provided with inverted V-arrangement catch 63, the inside angle of this V-arrangement catch is that 90 effects while spending are best, V-arrangement catch is respectively equipped with an inclined-plane 64 near the two ends of flour extraction pipe inwall, can better make the powder landing of getting together, between the both sides of described V-arrangement catch and powder delivery cylinder inwall, leave gap.
In order to be more applicable to and to facilitate the transport of powder, described conveyor screw is for there being shaft tube type conveyor screw, and described butterfly valve is electric butterfly valve or Pneumatic butterfly valve, and described electrical motor is three phase squirrel cage induction motor.
When use, open electrical motor, conveyor screw running, now, butterfly valve is opened, and powder passes through filler bin, conveyor screw, butterfly valve, flour extraction pipe successively, arrive on electronic scales, in the time that the powder weight on electronic scales reaches requirement, close electrical motor and butterfly valve simultaneously, by powder by, in the time of management butterfly valve, a little powder that may leak down, these powders can be attached on inverted V-arrangement catch, ensure the precision of powder on electronic scales.
Except structure of the present invention, all the other are prior art.
The above is the preferred embodiment of the present invention, for those skilled in the art, under the premise without departing from the principles of the invention, can also make some improvements and modifications, and these improvements and modifications are also regarded as protection scope of the present invention.
