Abstract
The invention discloses a pulse-free discharging screw rod device. Rotating blades are mounted on a screw rod; a tube wall is sequentially divided into a feeding section L1, a transition section L2 and a conveying section L3; a part, positioned at the feeding section L1, of a helical blade is a feeding helical blade; a part, positioned at the conveying section L3, of the helical blade is a conveying helical blade; the helical outer diameter ratio of the feeding helical blade to the conveying helical blade is 1:(1.3-1.5); a gap is formed between the lower end of the conveying helical blade and the inner bottom surface of the tube wall. By arranging the gap, a material, positioned at the bottom of a tube chamber, of a power coating does not rotate with the helical blade but is conveyed forwards by pushing of the helical blade, so that the powder coating is stably conveyed.
Description
Technical field
The present invention relates to technical field of conveying machinery, particularly relate 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.
Summary of the invention
The object of the invention is the technological deficiency for existing in prior art, and a kind of no pulse discharging screw rod device is provided.
The technical scheme adopted for realizing object of the present invention 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 invention 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.
Accompanying drawing explanation
Figure 1 shows that a kind of structural representation of no pulse discharging screw rod device.
Figure 2 shows that tube wall segmental structure schematic diagram;
Figure 3 shows that A-A direction view in Fig. 1.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is described in further detail.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
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 invention 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 the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
