Abstract
The utility model discloses a material hob device is rush out to acrotism, the pivoting leaf is installed to the hob, the pipe wall divide into pan feeding section L1, changeover portion L2 and pay -off section L3 according to direction of delivery in proper order, the spiral leaf is in pan feeding section L1's part is pan feeding spiral leaf, the spiral leaf is in pay -off section L3's part is the spiral feeding leaf, the spiral external diameter of pan feeding spiral leaf and spiral feeding leaf is than being 1: 1.3~1.5, the lower extreme of spiral feeding leaf with be provided with the clearance between the interior bottom surface of pipe wall. Through setting up the clearance, the rotation of spiral leaf is not followed to the material that makes powder coating be located the lumen bottom, and just carries forward under the promotion of spiral leaf, makes powder coating carry stably.
Description
Technical field
The utility model relates to technical field of conveying machinery, particularly relates to a kind of no pulse discharging screw rod device.
Background technology
Conveyor screw is conventional continuous conveyor.Work as manufacturing enterprise, especially the enterprise of powdery paints is produced, when using circular tube spiral conveyer conveying conventional in prior art to have the body of powder of high flow, this high flow and screw conveyer structure bring the problem such as discountinuity, pulsation and non-quantitation of powder conveying, the series of problems such as cause downstream mixing equipment or the fluctuation of Fabricating machinery negative pressure is large, material is excessive.
Utility model content
The purpose of this utility model is the technological deficiency for existing in prior art, and provides a kind of no pulse discharging screw rod device.
The technical scheme adopted for realizing the purpose of this utility model is: a kind of no pulse discharging screw rod device, it is characterized in that screw rod device is installed on described conveyor screw inner; Described conveyor screw comprises tube wall and tube chamber; In described tube chamber, screw rod is installed, described screw rod is provided with pivoting leaf;
Described tube wall is divided into pan feeding section L1, transition phase L2 and feeding section L3 successively according to throughput direction; Described pan feeding section L1 is positioned at the below of described material bin; The lumen diameter H1 of described pan feeding section L1 is less than the lumen diameter H2 of described feeding section L3; Described tube wall is described transition phase L2 in the part that the thickness of pipe between described pan feeding section L1 and feeding section L3 diminishes gradually; The ratio of the lumen diameter H1 of described pan feeding section L1 and the lumen diameter H2 of described feeding section L3 is 1:1.3 ~ 1.5; Described helical-blade is pan feeding helical-blade in the part of described pan feeding section L1, and described helical-blade is feeding screw leaf in the part of described feeding section L3; The spiral external diameter of pan feeding helical-blade and feeding screw leaf is than being 1:1.3 ~ 1.5.
Further, gap is provided with between the lower end of described feeding screw leaf and the inner bottom surface of described tube wall.By arranging gap, the material that powdery paints is positioned at bottom tube chamber does not rotate with helical-blade, and is just fed forward under the promotion of helical-blade, powdery paints is carried stable.
Principle of work of the present utility model and beneficial effect are: the pan feeding section lumen diameter of conveyor screw is less than the lumen diameter of feeding section, effectively can reduce fullness coefficient, make powder material when feeding section is carried, powder material is positioned at the latter half of feeding section lumen diameter all the time; The helical-blade of screw rod end can have the larger material of enough space stop capacity when discharging, avoid the generation of pulse discharging situation.

Detailed description of the invention
Below in conjunction with specific embodiment, the utility model is described in further detail.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Embodiment:
Be illustrated in figure 1 a kind of no pulse discharging screw rod device, include hopper and conveyor screw; Described conveyor screw comprises tube wall 1 and tube chamber 2; In described tube chamber 2, screw rod 3 is installed, described screw rod 3 is provided with pivoting leaf.
As shown in Figure 2, described tube wall 1 is divided into pan feeding section L1, transition phase L2 and feeding section L3 successively according to throughput direction; Described pan feeding section L1 is positioned at the below of described material bin; The lumen diameter H1 of described pan feeding section L1 is less than the lumen diameter H2 of described feeding section L3; Described tube wall 1 is described transition phase L2 in the part that the thickness of pipe between described pan feeding section L1 and feeding section L3 diminishes gradually, and described tube chamber 2 becomes large gradually at the internal diameter of described transition phase L2.Described transition phase L2 is preferably set to a gradient 6.This design of the present utility model can reduce the fullness coefficient of powdery paints effectively, and make powder material when feeding section is carried, powder material is positioned at the latter half of feeding section lumen diameter all the time; The helical-blade of screw rod end can have the larger material of enough space stop capacity when discharging, avoid the generation of pulse discharging situation.
Through measuring and calculating, the ratio of the lumen diameter H1 of described pan feeding section L1 and the lumen diameter H2 of described feeding section L3 is 1:1.3 ~ 1.5.
Accordingly, due to the difference of lumen diameter, described helical-blade is pan feeding helical-blade 4 in the part of described pan feeding section L1, and described helical-blade is feeding screw leaf 5 in the part of described feeding section L3; The spiral external diameter of pan feeding helical-blade 4 and feeding screw leaf 5 is than being 1:1.3 ~ 1.5.
As shown in Figure 3, gap S is provided with between the lower end of described feeding screw leaf 5 and the inner bottom surface of described tube wall 1.Because the particle diameter of powdery paints is less, because this gap S is preferably 5mm.By arranging gap S, the material that powdery paints is positioned at bottom tube chamber does not rotate with helical-blade, and is just fed forward under the promotion of helical-blade, powdery paints is carried stable.
The above is only preferred implementation of the present utility model; it should be noted that; for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
