Problems to be Solved by the Invention Japanese Patent Publication No. 58-53
In the crushing and sizing machine disclosed in Japanese Patent No. 937, the wire mesh used in such an apparatus is greatly deformed when pressed by a flat plate blade, but the wire mesh is inherently low in durability. In addition, the sizing material is easily deposited at the place where the flat blade starts to contact the wire mesh, and the fine powder of the crushed granule raw material easily adheres and accumulates on the rear side of the flat blade, and the sizing holes are clogged. Arises
There were problems with waste of the sizing material, quality control of the sizing material, sizing accuracy, cleaning and durability of the crushing and sizing machine.

In the pulverizing apparatus disclosed in Japanese Utility Model Laid-Open No. 6-57430, a cylinder provided with a large number of sizing holes is pressed by a pulverized body. However, there is a problem that a portion of the crushed body that intersects with the crushed surface and the rear side surface is a corner portion, and the rear surface of the crushed body is substantially parallel to the radial direction, and a large amount of crushed material is deposited on the rear side surface. In addition, there is a high possibility that the accumulation of the crushed material on the rear side of the crushed material may cause clogging of the sizing holes, sizing accuracy, waste of the sizing material, quality control of the sizing material, cleaning of the crushing and sizing machine. And the problem of durability has not been solved.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the conventional crushing and sizing machine and pulverized body, and it is extremely difficult for the sizing material to accumulate in the apparatus or adhere to the blade. It is an object of the present invention to provide a granule sizing apparatus capable of efficiently crushing and performing a granule sizing treatment without causing clogging of the granule sizing holes of the screen.

[0006]

According to the present invention, a screen provided with a large number of sizing holes is supported by a screen support frame to form a space, and is rotated concentrically with the screen support frame to rotate. In the sizing device, which slides on the inner surface of the screen by a blade disposed at the outer end of the screen to crush and size the sizing material in the space, the blade is rotated forward from the screen contact portion in the rotation direction. And a cylindrical portion extending rearward in the rotational direction from the screen contact portion.

An embodiment of the present invention is characterized in that the space is cylindrical. The blade has an inclination angle θ of 30 ° to 75 with respect to the radiation direction of the flat portion.
°, wherein the front edge in the rotation direction of the flat portion is inside the outer surface of the rotating body. If the inclination angle θ is larger than this angle range, there is a problem that the force for extruding the sizing material from the sizing hole is small and the sizing cannot be performed efficiently. When the inclination angle θ is smaller than this angle range, the resistance to the blade rotation by the sizing material increases, and the force for pushing the sizing material from the sizing hole is small, so that the sizing cannot be performed efficiently. Occurs. Another embodiment of the present invention is characterized in that an end of the screen is fixed to a radially extending holding member which is fastened by a screw in the screen support frame. With this configuration, there is an advantage that the screen can be supported in a small space. That is, in order to prevent the sizing material from being deposited at the part where the blade starts to contact the screen,
When the screen is made substantially cylindrical, the material inlet from the hopper becomes small, and the space for supporting the end of the screen is limited.In such a case, the screen is used without using a large screen support mechanism. Can be supported.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing a sizing apparatus according to an embodiment of the present invention. As shown in FIG. 2 which is a front view partially including a cross section, and FIG. 3 which is a side view partially including a cross section, the sizing device 1 is provided with a hopper 10 for charging a sizing material at an upper portion thereof. Inside the grain housing 12, a screen 14 made of a wire mesh provided with a large number of pores (not shown) is arranged in a cylindrical shape with the axis O being horizontal. As shown in FIGS. 4 and 5, the support structure of the screen 14 has screen fixing portions 30 on both sides of the lower end of the hopper 10 having a rectangular horizontal cross section. The screen fixing portion 30 pushes and moves the screen end fixing member 34, a holding member 38 fixed to the screen end fixing member 34 by the countersunk screw 36 to hold the end of the screen 14, and the screen end fixing member 34. For this purpose, a bolt 40 integrally formed with the holding member 38, a screen support frame 32 having a hole through which the bolt 40 passes, and a bolt 40 through the hole of the protruding member 44 are rotatably attached. And a fastening nut 46. The countersunk screw 36 and the bolt 40 are displaced in the direction of the axis O.

The screen fixing portion 30 having the above-described structure is configured such that the screen 14 end is sandwiched between the screen end fixing member 34 and the holding member 38 and the countersunk screw 36 is tightened to connect the screen 14 end to the screen fixing portion 30. Stick. Further, the bolt 40 is tightened by rotating the tightening nut 46, and the screen fixing portion 3 is fixed.
The end of the screen 14 fixed to 0 is moved obliquely downward (in the tangential direction of the cylindrical screen). As a result, the screen 14 is pressed against the screen support frame 32,
It is attached to the screen support frame 32. The screen support frame 32 has a tapered shape in which an edge portion in contact with the screen 14 becomes thinner toward the front end, and prevents fine powder of a sizing material from being deposited thereon. Wheel plate members 54 are provided at both ends in the axis O direction in the sizing housing 12.
The wheel plate members 54 and 56 are provided with a plurality of circular holes 60 for reducing the weight, and the wheel plate members 54 and 56 support both ends of the blade 50.

The blade 50 has a columnar shape having a notch extending in the axial direction. As shown in FIG. 1, one edge B of a plane 61 formed by the notch is in the radial direction A, The inclination angle θ of the plane 61 with respect to the radiation direction A is 45 °. The blade 50 is fixed to the wheel plate members 54 and 56 by screws 68. As shown in FIG. 3, the wheel plate members 54 and 56 holding the blade 50 are connected to a motor 72 via a shaft member 52 and a coupling (connection portion) 70 and are rotated.

The operation of the sizing apparatus 1 having the above configuration will be described. The sizing material is removed from the hopper 10 to the housing 12.
To The wheel plate members 54 and 56 are rotated by a coupling (connection part) 70 and a motor 72,
The blade 50 slides on the inner surface of the screen 14. A flat surface 61 extending from the edge line B of the blade 50 toward the front in the rotational direction into the cylindrical space slides while pushing the sizing material between the screen 14 and the sizing material. (Not shown) and are sized. At this time, the sizing material is not suddenly pushed out to the sizing holes (not shown) by the blade 50, and there is little possibility of clogging of the sizing holes (not shown). Blade 50
Behind the edge line B, the blade 50 and the screen 14 have a common tangential plane at the edge line B, and continuous cylindrical surfaces having different curvatures are gradually spaced toward the rear. Therefore, the fine powder of the crushed sizing material does not accumulate on the rear portion of the blade 50, thereby preventing clogging of the sizing holes of the screen.

[0012]

According to the present invention, the sizing material is very little deposited or adhered to the blade, the clogging of the sizing holes of the screen does not occur, and the sizing treatment can be performed efficiently. Has effects that can be performed. ADVANTAGE OF THE INVENTION According to this invention, there exists an effect which can support a screen reliably in a narrow space.
