Abstract
The utility model relates to a crusher cavity. The crusher cavity comprises an upper cavity and a lower cavity. The upper cavity is provided with a feeding port, and the lower cavity is provided with a discharging port; one side of the inside of the upper cavity, which is opposite to the feeding port, is provided with an arc first lining plate, the inside of the lower cavity is provided with an arc second lining plate, and the second lining plate is arranged under the first lining plate and connected with the first lining plate. Compared with the prior art, the crusher cavity integrates rough crushing and fine crushing into a whole by means of the upper cavity and the lower cavity. Further, according to the crusher cavity, the lining plates are in an arc shape and have a fixed center of curvature, thereby obtaining a high-strength space capable of bearing enormous impact load and the falling and impact effects of materials as well as the relatively large striking force generated due to high-speed rotation of a rotor punch, and further the materials can be lifted in a suspended mode and act on the lining plate of the arc internal surface of an upper frame in the tangential direction of the rotor punch to form rock-striking mode.

Hammer mill is a kind of for the machine at the broken medium-hard material of the industrial departments such as cement, chemical industry, electric power, metallurgy, as broken and operation in small, broken bits in the materials such as lime stone, slag, coke, coal.General disintegrating machine comprises disintegrating machine casing, is arranged on the crusher chamber in casing and is arranged on the rotor in crusher chamber.
Wherein, crusher chamber is used for holding broken material, and cooperatively interacts with rotor, and material is carried out to fragmentation.Yet existing crusher chamber is generally single cavity, and crusher chamber is narrow, and inlet amount is few.Meanwhile, existing crusher chamber is square cavity, can cause pellet distribution unbalanced, motion irregularity.
Utility model content
The utility model is that the shortcoming that overcomes prior art, with not enough, provides a kind of disintegrating machine cavity with high crushing efficiency.
The utility model is to realize by following technical scheme: a kind of disintegrating machine cavity, comprises upper cavity and lower chamber; Described upper cavity is provided with a charging aperture, and described lower chamber is provided with a discharging opening; In described upper cavity, a side relative with this charging aperture is provided with the first liner plate of a circular arc, is provided with the second liner plate of a circular arc in described lower chamber, and this second liner plate is arranged on the below of this first liner plate and is connected with this first liner plate.
Than prior art, the utility model is by used upper and lower two crusher chamber simultaneously, makes coarse crushing with in small, broken bits together with the two cooperates.Further, the utility model is set to circular arc by the liner plate of crusher chamber, there is the fixing center of curvature, have and can bear very big impact and carry the high-intensity space that falls, can stand the whereabouts of material, percussion, and produce larger impact force from the High Rotation Speed of rotor weight, material is lifted and suspended and along rotor weight, tangentially act on the liner plate of upper frame arc body inner face, form stone-crash-stone pattern.
As further improvement of the utility model, described the first liner plate is provided with a waveform circle-arc tooth.By circle-arc tooth being set, playing the effect that makes material splitting and change impulsive force and direction.
As further improvement of the utility model, described the second liner plate is provided with a waveform circle-arc tooth.By circle-arc tooth being set, playing the effect that makes material splitting and change impulsive force and direction.
As further improvement of the utility model, the top of described upper cavity is provided with a flat liner plate.
As further improvement of the utility model, the volume of described upper cavity is greater than the volume of lower chamber, and upper cavity, for the fragmentation of bulk materials, bears larger impact, and lower chamber is for the material of broken smaller piece.
As further improvement of the utility model, described lower chamber bottom is provided with a base plate, and this base plate is provided with a limit backplate perpendicular to this base plate; The top of described upper cavity is provided with a limit backplate perpendicular to this top; The side of described the first liner plate towards upper cavity inside is provided with backplate on one side.
As further improvement of the utility model, described a second liner plate dorsad side of lower chamber inside is provided with an impact rack.
In order to understand better and to implement, below in conjunction with accompanying drawing, describe the utility model in detail.
Accompanying drawing explanation
Fig. 1 is the structural representation of disintegrating machine cavity of the present utility model.
The specific embodiment
Refer to Fig. 1, it is the structural representation of disintegrating machine cavity of the present utility model.A disintegrating machine cavity, comprises upper cavity 1 and lower chamber 2; Described upper cavity 1 is provided with a charging aperture, and described lower chamber 2 is provided with a discharging opening.The volume of described upper cavity 1 is greater than the volume of lower chamber 2, and upper cavity 1, for the fragmentation of bulk materials, bear larger impact, and lower chamber 2 is for the material of broken smaller piece.
In described upper cavity 1, a side relative with this charging aperture is provided with the first liner plate 21 of a circular arc, and the top of this upper cavity 1 is provided with a flat liner plate 12.The top of described upper cavity 1 is provided with a limit backplate 13 perpendicular to this top; The side of described the first liner plate 21 towards upper cavity 1 inside is provided with backplate 13 on one side.
Concrete, described the first liner plate 21 is provided with waveform circle-arc tooth.By circle-arc tooth being set, playing the effect that makes material splitting and change impulsive force and direction.
In described lower chamber 2, be provided with the second liner plate of a circular arc, and this second liner plate 21 is arranged on the below of this first liner plate 21 and is connected with this first liner plate 21.Described lower chamber 2 bottoms are provided with a base plate 22, and this base plate is provided with a limit backplate 23 perpendicular to this base plate 22.Described a second liner plate 21 dorsad side of lower chamber 2 inside is provided with an impact rack 24.
