Abstract
The utility model discloses a crushing chamber of a crusher in the mechanical field of grain forage. The utility model comprises a crushing chamber casing body, a feed inlet, two screen plates, a rotor installed in the crushing chamber, and a primary crushing chamber formed between the crushing chamber casing body and the rotor, wherein the feed inlet and the two screen plates are arranged on the crushing chamber casing body. The utility model is characterized in that the two screen plates are respectively provided with at least two secondary crushing chambers in the circumferential direction, and each of the secondary crushing chambers is composed of a groove with an opening towards the inside of the crushing chamber. As a further improvement on the utility model, the casing of the crushing chamber of the upper part between the feed inlet of the crushing chamber and the transverse center line of the rotor of the crushing chamber is provided with a friction plate which is provided with holes or grooves. The utility model solves the technical problem that materials can be secondarily striked and crushed on a plurality of parts of the crushing chamber, improves crushing efficiency and reduces energy consumption.
Description
Technical field
The utility model relates to the disintegrating apparatus in the grain feed mechanical field, particularly the pulverizing structure of disintegrating apparatus.
Background technology
Existing pulverizer pulverizing chamber is made up of a pulverizing chamber and a secondary pulverizing chamber, and its secondary pulverizing chamber is located at two sieve plate joints of pulverizer bottom.Material enters in the pulverizing chamber, at first the accelerating region in pulverizing chamber is broken by the strike of high speed rotary hammer leaf, fly to the sieve sheet with higher speed then, in the full speed district of pulverizing chamber along compass screen surface high-speed motion and compass screen surface friction and fragmentation, when the secondary pulverizing chamber bottom pulverizer, clash on the surface of material and secondary pulverizing chamber, and the material flow direction is suddenlyd change, the circulation layer of material is destroyed, strengthened the relative velocity between material and hammer leaf, material has further been hit through the secondary pulverizing chamber time pulverize.But above-mentioned secondary pulverizing chamber only is arranged on the pulverizer bottom, has only when material process pulverizer bottom, just be subjected to this two-hit, thereby crush efficiency can not get effective raising.
The utility model content
The technical problem that the utility model solves provides a kind of material that can make all can be subjected to the pulverizer pulverizing chamber that two-hit is pulverized at a plurality of positions of pulverizing chamber.
The utility model comprises charging aperture and two sieve plates that are provided with on pulverizing chamber housing and the pulverizing chamber housing, a pulverizing chamber that constitutes between the rotor of installing in the pulverizing chamber housing and pulverizing chamber housing and the rotor, the circumferencial direction of described two sieve plates is provided with at least two secondary pulverizing chamber, and described secondary pulverizing chamber is made of the groove of opening in pulverizing chamber.
When material enters the pulverizing chamber accelerating region during pulverizing, broken by the strike of high speed rotary hammer leaf at accelerating region, in district at full speed along compass screen surface high-speed motion and compass screen surface friction and fragmentation, through above-mentioned two secondary pulverizing chamber the time, multiple impact takes place in the surface of material and secondary pulverizing chamber, and the material flow direction is repeatedly suddenlyd change, and the circulation layer of material is destroyed, strengthened the relative velocity between material and hammer leaf, material has further been hit through described secondary pulverizing chamber the time pulverize.
The utility model has increased the bump number of times of material in pulverizing chamber, has solved material and all can be subjected to the technical problem that two-hit is pulverized at a plurality of positions of pulverizing chamber, has improved crush efficiency greatly, has reduced energy consumption, and the excellent popularization using value is arranged.
As of the present utility model further perfect, be provided with friction plate at the charging aperture of pulverizing chamber and the top pulverizing chamber shell between the pulverizing chamber rotor cross central line.Described friction plate is provided with hole or groove, has increased the effect that material is pulverized in the accelerating region friction of pulverizing chamber, has further improved the efficient of pulverizing.In addition, described friction plate also can be arranged to dentation towards the surface in the pulverizing chamber.

Fig. 1, the utility model structural representation;
Fig. 2, friction plate schematic diagram of the present utility model.
Among the figure: 1 pulverizing chamber, 2 sieve plates (), 3 sieve plates (two), 4 secondary pulverizing chamber, 5 beater plates, 6 pulverizing chamber shells, 7 friction plates.
The specific embodiment
The pulverizing chamber of pulverizer comprises pulverizing chamber 1, is provided with sieve plate () 2, sieve plate (two) 3 in the pulverizing chamber 1, is provided with two secondary pulverizing chamber 4 at two sieve plates, 2,3 circumferencial directions.The quantity of described secondary pulverizing chamber 4 can have two, and is perhaps more a plurality of; The position of its secondary pulverizing chamber 4 can be arranged on any position of sieve plate.Sieve plate (one) 2 also can be provided with secondary pulverizing chamber 4 with sieve plate (two) 3 at pulverizing chamber 1 bottom joint.Can also be provided with beater plate 5 in the middle of the bottom of described secondary pulverizing chamber 4.
As of the present utility model further perfect, be provided with friction plate 7 at the charging aperture of pulverizing chamber and the top pulverizing chamber shell between the pulverizing chamber rotor cross central line, described friction plate 7 is provided with hole or groove.
Claims (5)
1, a kind of pulverizing chamber of pulverizer, comprise charging aperture and two sieve plates of being provided with on pulverizing chamber housing and the pulverizing chamber housing, a pulverizing chamber that constitutes between the rotor of installing in the pulverizing chamber housing and pulverizing chamber housing and the rotor, the circumferencial direction that it is characterized in that described two sieve plates is provided with at least two secondary pulverizing chamber, and described secondary pulverizing chamber is made of the groove of opening in pulverizing chamber.
2,, it is characterized in that being provided with described secondary pulverizing chamber at the described two sieve plate joints of pulverizer bottom according to the pulverizing chamber of the described pulverizer of claim 1.
