Description

The present invention is a raw seaweed foreign matter separation and removal device that is essential for separating and removing foreign matter from a raw seaweed/seawater mixture (raw seaweed mixture) and sending the selected raw seaweed to a built-in tank or the next device. Regarding the structure of clearance.

In the raw seaweed foreign matter separation and removal device, a clearance formed by the inner circumferential surface of the opening of the sorting casing and/or the sorting case ring and the outer circumferential surface of the rotary plate and capable of separating foreign substances efficiently and without being sucked in. It is necessary to ensure the structure (dimensions, ie, a gap of 0.1 mm to 0.08 mm).

However, the outer circumferential surface of the rotary plate wears out due to contact with raw seaweed and/or foreign matter. Due to this wear, the above-mentioned gap may not be secured, and, for example, foreign matter may be mixed into the sorted raw seaweed (good quality raw seaweed), and ultimately defective dried seaweed will be produced. Naturally, this defective dried seaweed leads to a decrease in cost and economic efficiency, leading to problems.

As a means for this purpose, there is a method in which a sorting case ring is attached to the sorting casing so that only this sorting case ring can be replaced when it wears out, but this method requires time and remains an economical problem.

In addition, as a document regarding wear, JP 2002-85017A states, ``Raw seaweed contains hard foreign matter, so in conventional clearance-type foreign matter separation devices, the rotation of the rotary disk separates the hard foreign matter from the rotary disk. The rotating and stationary plates rubbed against each other, causing wear and tear on the rotary and stationary plates, and after two to three weeks, the limit of adjustment was reached, and the clearance became large, making it impossible to separate foreign objects.Therefore, in the present invention, At least the surface portions of the parts constituting the clearance of the rotary disk and the fixed disk are made of a soft metal material, and a hard coating layer is formed on the surface.''

This invention is a physical method of preventing wear. Therefore, the method is limited to an anti-wear method rather than a treatment after wear occurs, and is not effective for treatment after occurrence. In addition, although we have searched and studied measures against wear, in principle, we have not found any literature related to this.

Under these circumstances, what is needed in the approximation field is a new mechanism that can maintain clearance accuracy (dimensions and/or suction work, etc.) even when wear occurs, and a new mechanism that can replace conventional equipment. There is a need for improvement plans that make effective use of.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a device for separating and removing foreign matter from raw seaweed, which is a preferred example of the present invention, and the structure of a rotating shaft and a shaft hole of this device for separating and removing foreign matter will be sequentially explained.

1 to 3-1, a raw seaweed foreign matter separation and removal device (good quality raw seaweed device) 1 includes a raw seaweed mixture tank 2 having an upper opening for pooling the raw seaweed mixture, and a raw seaweed mixture tank 2. For example, as shown in FIG. A circular hole (opening) opened from the surface 5-1 toward the back surface 5-2 of the annular sorting case ring 5 supported on the outer peripheral wall 301 standing above the inner bottom surface 300 (bottom) (no code) or the inner circumferential surface 3a of a circular hole (no reference numeral) opened from the front surface 3-1 to the back surface 3-2 of the sorting casing 3, as shown in FIG. 3-2. The rotary plate 7 is formed between the inner circumferential surface 3a of the sorting casing 3 or the inner circumferential surface 5a of the sorting case ring 5 and the vertical outer circumferential surface 7b of the rotary plate 7 (details will be described later). a clearance 6 (details will be described later), a rotating shaft 9 that supports the rotary plate 7 and is suspended from the inner bottom surface 300 of the sorting casing 3, and a center 302 of the sorting casing 3 that supports the rotating shaft 9. It is composed of a bearing 10 and a motor 11 that rotates the rotating shaft 9. In addition, as shown in FIG. 3-2, when the sorting casing 3 and the sorting case ring 5 are integrated, the sorting case ring 5 can be read as the sorting casing 3. Also, their functions are the same. Further, the other structure of the sorting casing 3 is similar to the sorting case ring 5 described above.

To explain the structure of the clearance 6, which is the key point of the present invention, in the example shown in FIG. 7b, and a pin corner inner circumferential surface 5b at the upper circumferential corner of the inner circumferential surface 5a of the circular hole of the sorting case ring 5. In addition, in the example of FIG. 3-2, the circumferential vertical outer circumferential surface 7b of the outer circumferential surface of the rotary plate 7, and the pin corner inner circumferential surface 3b of the upper circumferential corner of the inner circumferential surface 3a of the circular hole of the sorting casing 3. It is formed by

In each of these examples, the outer circumferential surface 7a of the rotating plate 7 has a circumferential vertical outer circumferential surface 7b with a height of, for example, 1 mm to 5 mm, preferably 1 mm to 3 mm, on the upper side, and a vertical outer circumferential surface 7b on the lower side. It is formed with an inclined converging outer circumferential surface 7c having a circumferential shape and having an inclined part. In the example shown in FIG. 3A, a pin corner inner circumferential surface 5b is provided at an upper circumferential corner of the inner circumferential surface 5a of the circular hole of the sorting case ring 5. Further, in the example shown in FIG. 3-2, a pin corner inner circumferential surface 3b is provided at an upper circumferential corner of the inner circumferential surface 3a of the circular hole of the sorting casing 3. The clearance 6 formed between the vertical outer circumferential surface 7b and the pin angle inner circumferential surface 5b (3b) is 0.8 mm to 3 mm, preferably 1 mm to 2 mm (gap).

1 and 2, reference numeral 20 in the figure is a hose, and this hose 20 is in communication with a raw seaweed mixture storage tank 21 that stores raw seaweed/seawater/water (referred to as raw seaweed). Raw seaweed is supplied to the raw seaweed mixed liquid tank 2 through the opening. A hose 25 in the figure supplies seawater or water to the raw seaweed foreign matter separation and removal device 1. In the figure, 26 is a pump.

In addition, in FIG. 1, etc., reference numeral 22 indicates a plurality of raw seaweed discharge ports provided on the inner bottom surface 300 of the sorting casing 3 from which sorted raw seaweed is taken out, and 23 indicates a pipe connected to the raw seaweed discharge port 22. The raw seaweed separated (sorted) in step 6 is transferred to a raw seaweed tank 27 (high-quality raw seaweed tank) that pools the raw seaweed through this raw seaweed discharge port 22 and piping 23, or to the following tank (not shown): (Secure the amount of raw seaweed that passes through with clearance 6).

In this example, the elevating means 30 (elevating device) shown in FIG. A position adjustment nut 32 having a second screw 3101 therein, a lower end outer surface 39a and an upper end surface of the rotating shaft 9, each having a fourth screw 3103 that engages with a third screw 3102 provided on the upper wall surface 32a of this position adjustment nut 32. An intermediate member 39 includes a lower wall 39a that contacts the lower wall 9a, and a fixing screw (39) provided above the intermediate member 39, passing through the intermediate member (39), and screwed onto the rotating shaft (9). -1) with a lock nut (33).

Therefore, to explain the operation of raising and lowering the rotary plate 7 (raising and lowering; the same applies hereinafter), first, unscrew the fixing screw 39-1 of the lock nut 33, which is screwed onto the upper end surface 9a of the rotary shaft 9. After the intermediate member 39 and the position adjustment nut 32 are set in a free state, the sleeve 31 is raised by screwing into or screwing back into the threaded portions of the intermediate member 39 and the position adjustment nut 32. As the sleeve 31 rises, the rotating plate 7 fixed to the sleeve 31 rises in the Y direction. To fix the rotating plate 7 in this raised position, the fixing screw 39-1 of the lock nut 33 is screwed into the rotating shaft 9 again, and the lower end surface of the lock nut 32 is brought into contact with the upper end surface of the intermediate member 39. By tightening the lock nut 33 in this manner, the intermediate member 33 and the position adjustment nut 32, the sleeve 31, and the rotating plate 7 are each fixed, and the rising of the rotating plate 7 is ensured. As the rotating plate 7 rises, the vertical outer circumferential surface 7b rises (see "A" to "C" in FIG. 4). That is, in response to the wear of the vertical outer circumferential surface 7b, it is raised and the dimension of the clearance 6 is ensured. In addition, when the lock nut 33 and the position adjustment nut 32 are operated during this opening adjustment, the flange piece 36 for position confirmation provided on the fixed side ring 34 that engages with the first screw 3100 of the sleeve 31 and the position adjustment The fixing pin 37 that fixes the collar piece 35 for position confirmation provided on the nut 32 is screwed in and screwed back. In the figure, reference numeral 38 denotes a connecting plate (stopping plate), which is provided between the rotary shaft 9 and the sleeve 31, and transmits the movement of the rotary shaft 9 to the sleeve 31 and the rotary plate 7. The characteristics during the rise will be described later.

In this example, the elevating means 40 shown in FIGS. 6(a) and 6(b) has a main body portion 43a of a base portion 43 mounted and fixed on the upper end 41a of the sleeve 41 via an intermediate member 42. do. This base portion 43 is fixed to the upper portion 9a-1 of the rotating shaft 9. Although not shown, the base portion 43 may have a structure in which it is fitted into or inserted into the upper portion 9a-1 of the rotating shaft 9. It has a structure (not shown) that locks cam levers 45 and 46, which will be described later. Cam levers 45 and 46 (which move in the same way and will be explained on the side of one cam lever 45) are provided on the main body portion 43a of the base portion 43 so as to be movable (up and down) via pivots 47 and 48. (It is pivoted eccentrically.) This cam lever 45 is provided with a chamfered notch 450 (460) at a corner 45-1 (corner 46-1) where the lower surface 45c (46c) and the upper surface 45d (46d) intersect. This notch 450 aims to avoid obstacles when the cam lever 45 is set up from a horizontal state (allows smooth movement). That is, in the case where the pivot shaft 47 of the cam lever 45 is eccentrically provided, smooth undulation is promoted, and movement from a horizontal state to a vertical state (erected state), and from a vertical state (erected state) to a horizontal state is facilitated. Move smoothly.

This eccentricity is caused by the fact that when the cam lever 45 is installed upright (in the directions a and b in the arrow view), the free portion 45b of the cam lever 45 comes into pressure contact S with the upper end surface 9a of the rotating shaft 9, and the cam of the cam lever 45 The range of the difference between the eccentric dimension A formed by the part 45a and the pivot 47 and the eccentric dimension B formed by the free part 45b and the pivot 47 (hereinafter referred to as "the eccentric dimension A and the eccentric dimension B") In other words, it is the push-up support dimension. In this embodiment, the eccentric dimension A is longer than the eccentric dimension B), the sleeve 41 rises (arrow Y). That is, by erecting the cam lever 45, the sleeve 41 is forcibly raised (in the direction of arrow Y) with one touch. As the sleeve 41 rises (the same goes for the descent), the rotating plate 7 fixed to the sleeve 41 rises, which causes the vertical outer circumferential surface 7b to rise (see "A" to "C" in FIG. 4). ), this is the structure in which the clearance 6 is maximized. That is, in response to the wear of the vertical outer circumferential surface 7b, it is raised and the dimension of the clearance 6 is ensured. Securing the dimension of the clearance 6 by this elevation is common to other elevating means 30, 50, and 60.

Moreover, this eccentricity is caused by the cam part 45a of the cam lever 45 coming into pressure contact S with the upper end surface 9a of the rotating shaft 9 due to the movement of the cam lever 45 to the horizontal state, and the difference between the eccentric dimension A and the eccentric dimension B. In the range (push-up support dimension), the sleeve 41 descends (opposite to the direction of arrow Y). In other words, by moving the cam lever 45 and the cam lever 46 (hereinafter, the cam lever 45 will be described as a representative) to the horizontal state, the sleeve 41 is forcibly and with one touch lowered in the opposite direction to the Y direction. As the sleeve 41 descends, the rotating plate 7 fixed to the sleeve 41 also descends.

That is, a pivot shaft 47 is provided at an eccentric position of the cam lever 45, and the cam lever 45 is movable using the pivot shaft 47 as a fulcrum. By pressing S, the position of the pivot 47 of the base portion 43 fixed to the sleeve 41 is raised and lowered, whereby the sleeve 41 and the rotary plate 7 are raised and lowered simultaneously, producing the same effect as described above.

In the elevating means 50 shown in FIG. 7, in this example, the boss portion 7d of the rotating plate 7 is fitted and supported on the upper end surface 9a of the rotating shaft 9, and is supported in the axial direction via a gap 51. ing. Further, a screw 5301 of the intermediate member 53 is engaged with a screw 52 carved in the annular thick portion 7d1 at the upper part of the boss portion 7d. Note that the screw 5301 also serves as a scale, and serves as an index of the rising dimension when the cap 54, which will be described later, is rotated and the rotary plate 7 is lifted. This cap 54 has a screw 5400 carved on the inside of the main body, and this screw 5400 engages with the screw 52, and by turning the cap 54 in a certain direction, the rotary plate 7 is raised (upwards). The rotating plate 7 rises by itself and the clearance 6 is secured. That is, the vertical outer circumferential surface 7b of the rotary plate 7 is higher than the surface 3-1 of the sorting casing 3 or the surface 5-1 of the sorting case ring 5 (moves upward in the Y direction). (Other elevating means 30 to 40, etc. move in the same manner. Omitted). In the figure, reference numeral 55 denotes a stop plate attached to the rotating shaft 9, and the rotating plate 7 is supported on the rotating shaft 9 using this stop plate 55. In the figure, reference numeral 56 indicates a gap (for example, a dimension of 5 mm, which is the same for other examples) formed between the stop plate 55 and the inner ceiling surface 54a of the cap 54. It has a structure in which the plate 7 moves up and down. In this example, rotation of the cap 54 causes the rotating plate 7 to rise (descend). Note that 57 is a stopper that stops the movement of the cap 54. Further, 58 is a spacer, which is installed between the upper end surface 9a of the rotary shaft 9 and the lid back surface 54b of the cap 54, and maintains the maximum raised position of the rotary shaft 9. The rest corresponds to the elevating means 30 and 40 described above.

In the elevating means 60 shown in FIG. 8, in this example, a sleeve 61 provided on the boss portion 7d of the rotary plate 7 is fitted onto the rotary shaft 9. An outer thread 61b is cut into the upper part 61a of the sleeve 61, and an inner thread 62a of the cap 62 is engaged with the outer thread 61b. Therefore, by rotating the cap 62, the sleeve 61 moves up and down. As the rotary plate 7 moves up and down with this elevation, the vertical outer circumferential surface 7b of the rotary plate 7 is moved to the surface 3-1 of the sorting casing 3 or the surface 5-1 of the sorting case ring 5, as in the example of FIG. 63 in the figure is a stop plate, which is a rotating shaft 9 and supports the cap 62. A gap (for example, a dimension of 5 mm) is formed between the upper end surface 9a of the rotating shaft 9 and the inner ceiling surface 62b of the cap 62.Other examples are the same. ) 64. The structure is such that the rotating plate 7 moves up and down within the range of this gap 64. In this example, when the cap 62 rotates forward and backward, the rotating plate 7 moves up and down within the range of the gap 64 in the direction of the arrow. It rises in the Y direction or descends in the opposite direction to the Y direction. In the figure, 65 is a stopper, and this stopper 65 is installed vertically on the upper end surface 9a of the rotating shaft 9 while penetrating the lower side of the cap 62. Therefore, the stopper 65 supports the cap 62 and synchronizes with the rotation shaft 9 by being fixed to the upper end surface 9a of the rotation shaft 9.The stopper 65 also stops the movement of the cap 62. The rest is similar to the above-mentioned elevating means 30-50.

9-1 and 9-2 are diagrams showing the relationship between the rotating plate 7, the rotating ring 70 provided on the outer peripheral end surface 7e of the rotating plate 7, and the pin corner inner peripheral surface 5b of the sorting casing 5. 2 is a diagram of an embodiment in which the outer circumferential surface 7a of the rotary plate 7 and the outer circumferential surface 70a of the rotary ring 70 are respectively constituted by an outer circumferential slope 7a1 and an outer peripheral slope 70a1. As an example, when a wear point occurs on either the outer circumferential slope 7a1 of the rotating plate 7 and/or the outer circumferential slope 70a1 of the rotating ring 70, other outer circumferential slopes 7a1 other than the wear place, Or, in order to ensure the relationship between the outer circumferential slope 70a1 and the pin corner inner circumferential surface 5b and to ensure the clearance 6, the lowering and/or rising of the rotary plate 7 and/or the rotary ring 70 is used. (Figures 4 (a) to (c) above are also omitted as they are the same). In the drawings, the outer peripheral slopes 7a1 and 70a1 have an inclined configuration from the upper side to the lower side toward the center, but it is also possible to have a reverse slope configuration from the lower side to the upper side toward the center. . Note that it is desirable that these sloped surfaces have a gentle slope.

As described above, in the present invention, the directionality of the slope structure of the outer circumferential surfaces 7a to 70a and the outer circumferential slopes 7a1 to 70a1 is free.
