Description

Low-noise smashing and screening machine

Technical Field

The utility model relates to an smash the sieve separator, especially relate to an smash sieve separator of low noise.

Background

At present, many trades often can involve the screening classification work of a large amount of solid materials, and is the biggest with drum-type sieve separator use amount in screening equipment to the sieve separator is that the rotational speed is very fast at the screening material, and the screening volume is great. In the production process of the zipper head, the zipper head is a whole piece after being die-cast, and the whole piece of zipper head needs to be placed into a crushing and screening machine for screening, so that the zipper head is screened out. The separating barrel of the screening machine is of a drum type, the separating barrel rotates, and the zipper puller can impact the inner wall of the separating barrel to send out huge noise. The huge noise can affect the surrounding workers of the crushing and screening machine, so that the noise generated by the crushing and screening machine during screening is very necessary to be reduced.

Disclosure of Invention

The utility model provides a little crushing and screening machine of noise during screening has solved the big technical problem of crushing and screening machine screening noise that exists among the prior art.

The above problems of the present invention are solved by the following technical solutions: the utility model provides a low noise smashes sieve separator, contains casing and rotatable separator barrel, the separator barrel is connected through pivot and casing, just the separator barrel nestification is in the casing center the last annular of separator barrel is equipped with a plurality of abatvoix, be equipped with a plurality of sound-absorbing cavities on the abatvoix. After metal products such as the zipper head enter the smashing and screening machine, smashing and screening are carried out through rotation of the separation barrel. The leading flank of separation bucket and casing is connected through the pivot, and the separation bucket rotates in the casing, and the inner wall of metal product striking separation bucket produces the noise, and the abatvoix that the separation bucket ring was set up can alleviate the noise. The sound-absorbing cavity on the sound-absorbing plate mainly plays a role in diffusing the noise transmitted from the separation barrel through the reflection of the inner wall of the sound-absorbing cavity, so that the purpose of reducing the noise is achieved.

Preferably, the separation barrel comprises an inner barrel and an outer barrel, and a vacuum sound insulation layer is arranged between the inner barrel and the outer barrel. A vacuum sound insulation layer is arranged between the inner barrel and the outer barrel of the separation barrel, and the arrangement can also reduce the noise transmission to a certain degree.

Preferably, the sound-absorbing plate is tightly attached to the outer wall of the outer barrel of the separation barrel, and the sound-absorbing plate rotates along with the separation barrel. The sound-absorbing plate is tightly attached to the outer wall of the separation barrel, so that the noise transmitted from the separation barrel can be treated by the sound-absorbing plate.

Preferably, the sound absorption cavities are hemispherical bulges and are uniformly distributed on the sound absorption plate. The sound absorbing cavity is a hemispherical bulge, and noise is reflected and transmitted on the inner wall of the sound absorbing cavity, so that the effect of reducing the noise transmission is achieved.

Preferably, the opening of the sound absorption cavity is attached to the outer wall of the outer barrel of the separation barrel. The opening of the sound absorbing cavity faces the outer wall of the separating barrel, so that the effect of processing noise can be achieved.

Preferably, the sound-absorbing plate is a sound-insulating rubber plate. The sound-absorbing board adopts a sound-insulating rubber plate, so that the effect of reducing noise is better.

Therefore, the utility model has the advantages of as follows: the sound-absorbing boards are fixed on the outer wall of the outer barrel of the separation barrel, so that noise can be better reduced; the sound absorbing cavity is a hemispherical bulge, and noise can be reflected and weakened on the inner wall of the sound absorbing cavity; a plurality of sound-absorbing cavities are uniformly distributed on the sound-absorbing plate, so that the noise can be reduced to the greatest extent; a vacuum sound insulation layer is arranged between the inner barrel and the outer barrel of the separation barrel, so that the noise can be reduced; the sound-absorbing board is a sound-insulating rubber board, and has the characteristics of convenient material taking and low cost.

Fig. 2 is a schematic view of the sound-absorbing board of the low-noise smashing screening machine of the utility model.

Description of the drawings: 1-shell, 2-acoustic board, 3-outer barrel, 4-inner barrel, 5-vacuum acoustic layer, 6-acoustic cavity.

Detailed Description

The technical solution of the present invention is further specifically described below by way of examples and with reference to the accompanying drawings.

Example (b): a low noise crushing and screening machine as shown in figure 1. The shell 1 is a cube, a regular hexagon opening is formed in the center of the rear side face of the shell 1, and the area of the regular hexagon opening is larger than the cross sectional area of the separating barrel of the crushing and screening machine. The separation barrel is connected with the front side surface of the shell 1 through a rotating shaft, and the separation barrel rotates in the shell 1. The separating barrel of the crushing and screening machine is divided into an outer barrel 3 and an inner barrel 4, and the cross sections of the outer barrel 3 and the inner barrel 4 are both regular hexagons. A vacuum sound insulation layer 5 is arranged between the outer barrel 3 and the inner barrel 4, and the vacuum sound insulation layer 5 mainly plays a role in reducing noise. The outer barrel 3 of the separation barrel is fixed with a layer of sound-absorbing board 2 on the outer wall, the sound-absorbing board 2 tightly wraps six side walls of the separation barrel, and the sound-absorbing board 2 is made of a sound-insulating rubber plate. Evenly distributed a plurality of sound-absorbing chamber 6 on the abatvoix 2, sound-absorbing chamber 6 is the hemisphere arch, and the opening spreads from the separation bucket towards the separation bucket outer wall, and the noise reflects the transmission at the inner wall in sound-absorbing chamber 6, reaches the effect that alleviates the noise.
