Abstract
The invention relates to a high-precision additive metering screw conveyor comprising a screw conveyor. Cutter bodies are arranged on a spiral shaft at a feeding opening of the screw conveyor; stirring rods are arranged on the spiral shaft close to a discharging opening of the screw conveyor; the rotation diameter DN2 of each cutter body is more than twice the diameter DN1 of a spiral blade; and the rotation diameter DN3 of each stirring rod is more than the diameter DN1 of the spiral blade and is less than the internal diameter of a spiral pipe. The high-precision additive metering screw conveyor provided by the invention has the advantages that the screw conveyor is uniform in feeding and discharging, and the impact on a metering scale is reduced by virtue of the cutter bodies at the feeding opening of the screw conveyor and the stirring rods at the discharging opening of the screw conveyor, so that the additive metering precision is greatly improved, and the property stability of finished mortar can be improved.
Description
Technical field
The present invention relates to a kind of dry mortar mixing plant additive metering screw machine, relate in particular to a kind of high accuracy additive metering screw machine.
Background technology
In the dry mortar mixing plant industry, although additive shared ratio in mortar product is less, but very large to the performance impact of its mortar product, and the cost compare of additive is high, so require the measuring accuracy of additive just high, for extraordinary mortar, measuring accuracy requires just higher.At present, its measuring accuracy of additive metering screw machine of employing can only reach 1%, mixes variable-frequency motor, also can only reach about 0.5%, so the performance of mortar product is very unstable.
Summary of the invention
For overcoming the deficiencies in the prior art, the purpose of this invention is to provide a kind of high accuracy additive metering screw machine, improve measuring accuracy, make the mortar product stable performance.
For achieving the above object, the present invention is achieved through the following technical solutions:
A kind of high accuracy additive metering screw machine comprises screw machine, and the helical axis at screw machine charging aperture position is provided with cutter hub, near the helical axis at discharging opening position puddler is set at screw machine; The tactical diameter DN2 of described cutter hub is greater than 2 times of helical blade diameter DN1; Described puddler tactical diameter DN3 is greater than helical blade diameter DN1, less than the helix tube internal diameter.
Described cutter hub is eight, distributes in four pitch along the backpitch line direction of helical blade.
Described cutter hub is L shaped structure.
Described puddler is divided into two groups, and every group of four puddlers are evenly distributed in the cross section of helical axis, and two groups of puddler axial spacings are between 1/2 ~ 1/4 pitch, and two groups of puddlers cross each other into miter angle at axis projection.
Compared with prior art, the invention has the beneficial effects as follows:
Utilize the cutter hub of screw machine charging aperture and the puddler of discharging opening, make the charging of its screw machine, discharging even, reduce the impact to weighing balance, thereby the measuring accuracy of additive is greatly improved, the stability of mortar product improves.

The specific embodiment
Below in conjunction with Figure of description the present invention is described in detail, but should be noted that enforcement of the present invention is not limited to following embodiment.
See Fig. 1-Fig. 5, a kind of high accuracy additive metering screw machine comprises screw machine 2, and the helical axis 9 at screw machine 2 charging apertures 4 positions is provided with cutter hub, near the helical axis 9 at discharging opening position puddler 6 is set at screw machine 2; The tactical diameter DN2 of described cutter hub 3 is greater than 2 times of helical blade 8 diameter DN1, and peripheral speed is very fast, can break up the easily agglomerating additive material of charging aperture 4 inside, makes it uniformly to screw machine 2 feed; Described puddler 6 tactical diameter DN3 are greater than helical blade 8 diameter DN1, and less than helix tube 7 internal diameters, puddler 6 can make near the material stirring that helical blade 8 is delivered to the discharging opening loose, and discharging is even, reduces the impact to weighing balance 1.
Described cutter hub 3 is eight, along backpitch line direction evenly distribution in four pitch of helical blade 8.
Described cutter hub 3 is L shaped structure.
Described puddler 6 is divided into two groups, and every group of four puddlers 6 are evenly distributed in the cross section of helical axis 9, and two groups of puddler 6 axial spacings are between 1/2 ~ 1/4 pitch, and two groups of puddlers 6 cross each other into miter angle at axis projection.
During use, when material passed through screw machines 2 charging aperture 4 from additive bin 5, easily agglomerating additive material was at first broken up by cutter hub 3, then evenly gave screw machine 2 feed; Screw machine 2 near discharging opening, two groups of puddlers 6 are delivered near the looser of the additive material stirring discharging opening with helical blade, make its discharging even, and are smaller to the impact of weighing balance 1.The present invention is equipped with variable-frequency motor again, PLC by mixing plant control centre, according to the dosage that adds that enters weighing balance 1, screw machine 2 is carried out VFC, along with the increase that enters weighing balance 1 additive part by weight, the motor speed of screw machine 2 descends, when weighing balance 1 reaches setting value, the motor of screw machine 2 stops, finish the batching of one-period, can realize that the additive measuring accuracy reaches 0.2%, absolute precision can reach 20g, thereby the stability of mortar product is very significantly improved.
The present invention utilizes the cutter hub of screw machine charging aperture and the puddler of discharging opening, makes the charging of its screw machine, discharging even, reduces the impact to weighing balance, thereby the measuring accuracy of additive is greatly improved, and the stability of mortar product improves.
