Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a tilted vibrating sieve, and more particularly to a tilted vibrating sieve having multiple sieve surfaces.

[Conventional technology]

Conventionally, this type of tilted vibrating sieve has a multi-stage slanted sieve surface, and as the raw material moves from the supply side end face to the discharge side end face, the sieve at each stage is The sieve surfaces of different sizes separate particles into groups of each size, which are discharged from the discharge chute and used for subsequent processing steps. Figure 3 shows a conventional tilted vibrating sieve 1o. ing.

1 is a side plate of the inclined vibrating screen 10, which is provided on both sides, 2a,
2b, 2c, and 2d are sieve surfaces, and the illustrated example shows four stages of inclined sieve surfaces, and the lengths of the sieve surfaces are the same from the top to the bottom.

3 is a raw material supply end, 4 is a supply side end face, and 5 is a discharge side end face. 6 is a driving machine t of the tilted vibrating screen 10, and 7 is a support device. The raw material is supplied from the supply end 3, and as it moves from the supply side end face 4 to the discharge side end 5, it passes through sieve surfaces 2a, 2b, 2c with different sieve mesh sizes.

2d and is divided into particle groups of each size.

FIG. 4 shows a crushing unit using the conventional tilted vibrating sieve 10 shown in FIG.
It is divided into a, 8b, 8c, and 8d. 9 indicates a hopper, 11 a crusher, 12 a drive device for the crusher 11, and 13 a pedestal.

The particle groups sized for each size are used for subsequent processing steps by a crusher 11 and a conveyor (not shown).

[Problem that the invention seeks to solve]

However, in the conventional tilted vibrating sieve, the supply side end face and the discharge side end face of both side plates are vertical, so when a chute is installed and used in a crushing unit combined with a crusher, etc., the tilted vibrating sieve is This increases the space required, including the overall length and height, making it difficult to downsize.

In particular, as the number of stages of the multistage sieve surface of the tilted vibrating sieve increases, the difficulty in miniaturizing the sieve increases.

In recent years, there has been a need for tilted vibrating sieves to have a structure that has a wide range of grain sizing effects in a limited space, but this problem is difficult to solve with the above-mentioned conventional tilted vibrating sieves.

[Means for solving problems]

In order to achieve the above object, the present invention makes the supply side end faces of both side plates of a tilted vibrating sieve consisting of multistage sieve surfaces vertical, and the discharge side end faces are notched inward to sequentially reduce the length of the sieve faces of each stage. It was designed to make it smaller.

[For production]

The present invention has the following effects due to the above configuration. That is, since the discharge side end surfaces of both side plates of the inclined vibrating sieve consisting of multistage sieve surfaces are notched inwardly, chutes for guiding the sized particles can be placed close to the notches, and the A very wide range of particle size effects can be obtained in a small space.

〔Example〕

FIG. 1 shows the configuration of an embodiment of the present invention.

In FIG. 1, the description of the parts common to the structure of the conventional tilted vibrating screen 1o will be omitted since it is not shown in FIG. 5a is the end face on the discharge side, and both side plates 1 are connected to the inclined vibrating sieve 10.
The sieve surfaces 2a, 2b, 2c, and 2d of each stage are cut out at a predetermined angle on the inside thereof, and the lengths of the sieve surfaces 2a, 2b, 2c, and 2d are sequentially reduced from the top to the bottom.

FIG. 2 shows the crushing unit 1 using the inclined vibrating sieve 10 according to the embodiment of the present invention shown in FIG.
, 8d, and both side plates 1 of the inclined vibrating sieve 10.
Inclined vibration f! on the periphery of the discharge side end face 5a of 110 are placed close to each other with a gap that does not impede the smooth operation of the 110. In this way, according to the above embodiment, since the chute 8 for guiding the sized particles can be disposed close to the notch, the multi-stage sieve surface can be used in a limited space such as a crushing unit. A wide range of grain sizing effects can be obtained.

In FIG. 1, the discharge side end surface 5a is formed by cutting out both side plates 1 at a predetermined angle inside the inclined vibrating sieve 1o, but in other embodiments, the discharge side end surface 5a is cut out from the sieve surfaces 2a, 2b of each stage.
, 2c, and 2d, it is also possible to make the notches step-like, and the point is to obtain a very wide range of grain sizing effects in a limited space.

〔Effect of the invention〕

As is clear from the above embodiments, in the present invention, the discharge side end faces of both side plates of the inclined vibrating sieve consisting of multi-stage sieve surfaces are notched inward, so that chutes for guiding the sized particles are placed close to the notch. It is possible to obtain a particle sizing effect over a wide range in a limited space. Furthermore, when using the tilted vibrating sieve in a crushing unit, etc., the required space such as the overall length and height including the tilted vibrating sieve can be reduced, making it possible to reduce the size and weight of the equipment. The effects are enormous.
