Description

[Detailed description of the invention] The present invention relates to a vibrating sieve device.

A sieve screen is used to sieve various powdered or granular materials, and a so-called vibrating sieve device built into a vibrator is often mentioned. The sieve must be installed in the vibrator, but conventionally, the sieve I
nIt made me nervous.

That is, FIG. 15 is a sectional view of the main part of the vibrating sieve device, and in the figure, a ball receiving plate (201) is fixed at the bottom 0111 inside the trough (200), and a large number of holes (20

06a) (206h) are formed with screws, and oaks (208a) (208h) are screwed onto these screws, and by tightening these, the sieve screen (204) is tensioned. The outer nuts (207a) (207h) are for locking.

When the trough (200)' is vibrated, the rubber ball b jumps and collides with the sieve screen (204). This improves the efficiency of the sieve as claimed, but if the sieve screen (204) is partially damaged after being used for a certain period of time, the sieve screen body (204)

The sieve screen body (203) must be loosened and removed, and a new sieve screen body (203) must be secured and tensioned, but this process requires a lot of effort. Trough (2
Although not shown, a vibration drive unit and an elastic member are provided below the trough (200), and the trough (200) is located at a height. The damaged sieve screen body (203) must be removed from such a trough (200) and a new sieve screen body (203) must be installed on this trough (200). In other words, the location of replacement and tensioning work is specified, which can be quite difficult work in some cases.

Further, although FIG. 15 shows the case of a single-stage sieve screen, in the case of a so-called multi-stage sieve in which several stages are stacked one above the other, replacement work becomes even more difficult. Also, it is not possible to tension many sieve screens at once; they must be tensioned and stacked one on top of the other, starting from the bottom.

The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a complete vibrating sieve device that facilitates the replacement of sieve screens. According to the first aspect of the present invention, this object is achieved by arranging a plurality of frames in which a sieve screen is fully tensioned in a trough connected to an excitation part, one above the other, and using a pressing member to This is achieved by a vibrating sieve device, which is characterized by holding the body under pressure in the vertical direction within the trough.

According to the second aspect of the present invention, the tranviter coupled to the vibrating section has a first frame body that receives all of the balls for impact, and a first frame body that is superimposed above the first frame body. A plurality of pairs of the second frame body with the sieve screen fully stretched are stacked one on top of the other -L, and the plurality of pairs of the first frame body and the second frame body are all vertically moved in the transformer by a pinching member. This is achieved by using a vibrating sieve device ffi, which has the following characteristics:

Also, according to the third invention of the present invention, the purpose of "υ-, h" is 7
Jl+ 41e Combined with capital 1. In the trough, a ball for covering is received on the lower side, and a sieve screen is fully stretched on the upper side.
This is achieved by a vibrating sieve device characterized in that a plurality of troughs are arranged with claws above and below, and the plurality of frames are held under pressure in the vertical direction within the trough by a clamping member. be done.

The head of 9 (il) is pressed by the engaging member: !10), and the tip of the engaging member (90) is pressed against the inner wall of frame C) 9), causing a slight deformation. . The sieve screen 6D is thus attached to the frame (39) under tension.

The rotating vibration 1j mounting according to the embodiment of the present invention is constructed as described above, and its operation and effects will be explained next.

Electric motor CI! 41 When fully driven, the drive rotation shaft (the clock rotates, and along with this, the balance weight D rotates clockwise as shown in Fig. mFA and Fig. 1313. Bearing link installed in the power, i.e. crankbin T39)
rotates with a radius δ around the rotating shaft (one axis of the paulownia wood).As a result, the drive unit mounting member (7) fixed to the crank bin (39) also rotates with a radius δ. This is accompanied by a casing (1) as shown in the figure.
), therefore, the sieve screen assembly (4) vibrates in an elliptical and elongated circle in the plane of its mesh surface from the material supply flII end toward the discharge end, and at the exit end υF ( The so-called swirling vibration itself is well known.When powdered material to be sieved is fed from the material inlet (3) to the sieve screen assembly (4), the material is The material that should be under the sieve quickly reaches the oil mesh and is efficiently sieved. With the vibration of the casing (lj), the rubber ball b jumps on the receiving plate (fil). Sieve screen (69) k. This further improves the sieving efficiency. The sieve from the sieve screen (61θ) passes through the hole G of the ball receiving plate (64J) and falls onto the lower sieve screen (611). Even in this case, the material under the sieve can be sieved efficiently using the ball holder + fiCi71] hole e.

The entire material under the sieve passes through the 3rd glue 1 exit (5c) and is discharged to the outside.
(6) 9 Rust occurs when the material flows toward the center (1).
Since the screws are guided by the screws, it is possible to prevent the metal from accumulating on the head of the oak (102) and the head square root bolt (6).

The center of gravity G of the balance weight 6η is in the opposite direction with respect to the crank bin (field) and the J axis (row's 'J111 center), so the centrifugal force J'' generated by the rotation of the balance weight 6η, u casing (1), The entire mounting force (7) is in the opposite direction to the inertial force F1 acting on the crankbin (Sakaki). FI and F2 are the same size. etc. shall be designed.In addition to this, Niji 1.3
As shown in Figure A and Figure 13B, the inertial force F1 and the centrifugal force F, - always cancel each other out both in the direction along the center line C-C of the casing (IJ) and in the direction perpendicular to this, and the base ( The vibration force transmitted to 9) is minimized.Although the moment of inertia at the center of the entire device & IC-C is quite small, as mentioned above, the inertial force F and the centrifugal force F always cancel each other out. The casing (11) can perform stable movements as described above.
9) The unbalanced portion of the force transmitted to the vibration isolating spring 0υ is completely absorbed.

In particular, in this example, the coil spring (Ilb) embedded in the rubber (lla) is used as a vibration-proof spring, so the viscosity coefficient of the spring is large and it moves erratically when starting and stopping the device. It is possible to start and stop the movement stably without any trouble.

In this embodiment, the casing (11'e) is supported by supporting rods (2) so as to be able to rotate and vibrate, but compared to the conventional structure in which the casing is supported by so-called sliding metal, it has a frame-like structure. Moreover, there is no need for troublesome adjustment work such as centering, there is no need to worry about wear, and there is no noise.On the other hand, the drive section (8) does not use a bevel gear as in the past, so it is much more efficient. It's quiet.

11ζ, the sieves iJY and J can be easily exchanged in non-examples. That is, bolt (130a) (1:3
0h) and nut (1:31aX131h) t Loosen the cover tightening tool (5 levers 52h) and cover (2)?
Remove the sieve screen assembly (4) and remove the casing (take it out from the IJ and place it in a place where it is easy to work on). +6

1), remove the Nando (1 (12)) and remove the 11 net (61
) 'Take out the lc. The tension setting of the sieve screen having a value of λ is carried out in the same manner as described above.
Assemble it into the casing tIJ in the order shown in the figure, put gold on the cover (2), fully apply the cover fasteners (52a) (52h), and tighten the nuts (131a) on the bolts (130a) (1: (Oh)). (131h) are screwed together and tightened, the sieve screen assembly (4) is held under pressure within the casing (1).

Conventionally, the work was difficult because the sieve screen had to be replaced inside the casing (IJ) located at a fairly high position 1a, but in this embodiment, the work can be easily done as described above.Especially In the case of a multi-stage sieve screen as in this example, even when only the lower sieve screen needs to be replaced using the method shown in FIG.
200), and after replacing it, I had to do the tensioning work again. However, in this embodiment, after taking out the casing (from 11 to 9), the sieve screen can be removed only from the 8-lined sieve frame, and the tension installation can be carried out in one go, so the work efficiency is much faster than in the past. Become.

Furthermore, compared to the conventional example shown in FIG. 15, this embodiment requires special processing on both ends of the sieve screen, and only retaining members (90),
Since it is only necessary to clamp it with a clamping member (9υ, packing 1921 (!J3), etc.), the manufacturing cost can be reduced.

FIG. 14 is a sectional view similar to FIG. 2 of the essential parts of a rotating vibrating sieve device according to another embodiment of the present invention, but corresponding parts in FIG. 2 are designated by the same reference numerals. , their detailed explanation will be omitted.

In the first embodiment, the lower corrugated board receiving frame (541 and the lower sieve frame L) are used.
i191 is also separate from the upper cardboard receiving frame (63) and the upper sieve frame (6), but in this embodiment, these are integrated. That is, as shown in FIG. A ball holder plate (57I) is fixed to the lower part of the lower frame (11, 8), and J: and Q sieve screens t611 are tensioned to the tensioning devices (60a) (601) to the upper part. .The upper frame (120) is superimposed on the lower frame (118) with a band-shaped packing ((i21 'c), and the lower frame (11, 8
), the ball holder is fixed to the lower part of the plate ((), and the sieve screen is tensioned to the upper part by tensioning tools (68a) and (68b).

This embodiment also has the same effect as the first embodiment, but by integrating the ball receiving frame and the sieve frame, the number of frames is halved, so it is possible to incorporate the casing (1). Made by f.
And the work of taking it out from the casing (1) becomes faster.

Although the embodiments of the present invention have been described above, the present invention is of course not limited thereto, and various modifications can be made based on the technical idea of the present invention.

For example, in the above embodiments, a rotating vibration device has been described, but the present invention can also be applied to a general vibration device.

Furthermore, although a two-stage sieve has been described in the above embodiments, the present invention is also applicable to a single-stage sieve.

Further, in the above embodiments, a vibrating sieve device of a rotating vibration type and a ball sieve type has been described, but it is also applicable to a vibrating sieve device other than a ball sieve type. In this case, the ball receiving frame uM) (63) is omitted in the above embodiment.

In the above embodiment, the cover (2) is attached to the sieve screen assembly (4).
Place it on top of the casing (11) and attach it to the casing (11) with an Eribolt nut to all the fasteners (52a x 52h), so assemble the cover (4) at the same time as installing the cover (2).
The material is held in place by clamping. This reduces the number of parts, but in the case of an open type without a cover (2), the assembly (4) is directly clamped and held by the fasteners (52a) and (52b). You may try to do it.

As described above, according to the vibrating sieve device of the present invention, replacing the sieve screen becomes easier than before. This effect is particularly noticeable in the case of multistage sieves.
