Description

[Detailed description of the invention] This invention smoothly discharges powdered materials such as compound feed, cement, fertilizer, etc. stored in the storage can body in a well-mixed state, and achieves the mixing effect and quantitative discharge. The present invention relates to a table feeder that efficiently performs the effects, makes the flow of powder and granular material in a mixing tank smoother than before, and makes it possible to increase the amount of discharge.

The conventional table feeder of the same type has an upper table and a bottom wall plate of the mixing tank body horizontally, and an outlet formed in the center of the upper table and a space between the outer peripheral edge of the table and the inner wall surface of the mixing tank body. 〓 and an outlet formed by the bottom wall plate, and a discharge port at a suitable location on the outer periphery of the bottom wall plate. The lower blade is installed close to the top surface, but since the upper table and the bottom wall plate are horizontal, there is a large flow resistance of the powder and granules, so a large amount of powder and granules can be conveyed in a short time. It had some drawbacks, such as being unsuitable.

The present invention solves these drawbacks, and has a cylindrical mixing tank in the upper part covered by a bottom wall plate with a lower opening inclined outward and downward and a discharge port provided on the outer side. An upper table is provided in which the upper end periphery of a truncated conical cylindrical inner outlet outer wall plate is joined to the inner periphery of an annular upper wall plate that slopes inwardly and downwardly so that the inner and outer outlet ports are provided outside the outer periphery and the inner periphery. It has a peripheral discharge type upper impeller that is fixedly installed and rotates close to the top surface of the table, and a peripheral discharge type blade that rotates below the upper table close to the top surface of the bottom wall plate, A lower impeller is fixed to the outer upper surface of the impeller below the outlet, and an annular receiving plate inclined inwardly and downwardly, covering the lower part of the outer outlet, is fixed to a drive shaft provided at the center of the mixing tank body; The peripheral part of the shaft is covered by a truncated conical cylindrical spinner connected to the lower impeller,
The powder and granules stored in the storage tank body connected to the upper part of the mixing tank can pass through the inner and outer outlet and are discharged from the discharge port by rotating the upper impeller and the lower impeller by operating the drive shaft. It is characterized by the following.

Next, the present invention will be explained with reference to the attached drawings. As shown in FIGS. 1 and 2, the mixing tank body 1 has a lower opening of a cylindrical peripheral wall 2 that is inclined outwardly and downwardly, and a discharge port 3 on the outer side. It is covered by a bottom wall plate 4 provided with.

At the upper part of the inner peripheral surface 5 of the peripheral wall 2 of the mixing tank body 1, the outer periphery of a plurality of upper table fixing plates 6, 6 (the figure shows the case of eight plates) is attached to the table fixing plates 6,
6... are fixed to each other in a radial pattern (outer radial shape) at equal intervals with a slight shift in the same direction with respect to the center line of the mixing tank body 1, and an annular upper wall plate is attached to the upper surface of the mixed tank body 1. A truncated conical cylinder is attached to the inner circumferential edge of the upper wall plate 7 so that the inner circumferential edge of the upper wall plate 7 and the outer circumferential edge of the upper wall plate 7 are inclined inwardly and downwardly so that an inner outlet 8 and an outer outlet 9 are formed on the inner side of the inner circumferential edge and the outer side of the outer circumferential edge, respectively. An upper table 11 to which the upper end periphery of an inner outlet outer wall plate 10 of a shape is joined is fixed.

As shown in FIG. Eight hook-shaped blades 14, 14..., a portion of which is bent concavely in the direction of rotation, are arranged such that the lower edge 15 thereof is close to the top surface of the bottom wall plate 4, and the outer upper surfaces of the blades 14, 14... are connected. A lower impeller 17 to which is fixed an annular receiving plate 16 which covers the lower part of the outer outlet 9 and which is inclined inward and downward is attached to the mixing tank can body 1 so that both impellers 13 and 17 rotate in synchronization in the same direction. A common square drive shaft 1 penetrates through the center of
A truncated conical cylinder whose upper peripheral wall forms the inner wall plate part 19 of the inner outlet 8 and whose lower end peripheral edge coincides with the lower end edge of the lower impeller 17 is attached to the peripheral part of the drive shaft 18. Then, a spinner 20 whose abutting portion with the blade 17 is joined is installed.

The drive shaft 18 is supported by a bearing 21 provided on the bottom wall plate 4, and a conical cap 22 of a size that does not obstruct the opening of the inner outlet 8 is attached to the upper end. It is fixed to the drive shaft 18 using a square hole boss.

Next, to explain the function of the present invention, the mixing tank can body 1
A storage tank can body 23 is connected to the upper part of the storage tank can body 23.
When powder and granular materials such as feed are introduced and accumulated in the tank, the powder and granular materials fall into the mixing tank body 1 through the inner and outer outlet ports 8 and 9, and some of them fall into the annular upper wall plate 7 of the upper table 11.
It accumulates on the bottom wall plate 4 in a state where it is deposited on the annular receiving plate 16 of the lower impeller 17. In this state, the drive shaft 18
When the upper impeller 13 and the lower impeller 17 are rotated in the direction of arrow R, the powder and granules flow through the inner outlet 8.
As it flows into the mixing tank due to natural fall,
From the outer outlet 9, natural fall and upper impeller 1
3, the powder and granules on the annular upper wall plate 7 of the upper table 11 are scraped in the outer circumferential direction and flow onto the annular receiving plate 16 of the lower impeller 17, and due to the rotation of the lower impeller 17, the annular The powder and granules that flow into the mixing tank from the receiving plate 16 and from the inner and outer outlet ports 8 and 9 are mixed and discharged to the outside from the discharge port 3.

In this invention, most of the weight of the powder and granular material stored in the storage tank body is received by the annular upper wall plate of the upper table and the annular receiving plate of the lower impeller, reducing the weight applied to the mixing tank. The rotational resistance of the impeller is small, and the upper surfaces of the annular upper wall plate, annular receiving plate, and bottom wall plate form slopes, so the powder and granules flow smoothly, and the drive shaft can be operated with small horsepower. This has excellent practical effects such as making it possible to transport a large amount of powder or granular material in a short period of time.
