Abstract
The utility model discloses a staged grinder which comprises a machine body, wherein a grinding cavity is formed in the machine body; a grinding device which is a cyclone type grinding device is arranged in the grinding cavity and below the grinding cavity; a material inlet is formed at the lower end of the grinding cavity, and a material outlet is formed at the upper end of the grinding cavity; the grinding device is fixed on a transmission shaft in the grinding cavity; the transmission shaft is driven by a motor; the grinding cavity and the motor are respectively fixed on a supporting frame; two ends of the transmission shaft are fixed on the supporting frame through bearings; and one end of the transmission shaft is connected with the motor through a belt wheel. By a two-stage cyclone type separation system, a screen is not used, so mechanical blocking is avoided, and the working efficiency is improved; moreover, the staged grinder is energy-saving and efficient and occupies a small space; the shortcomings of the conventional multi-group and multi-stage type loosening, grinding and grading method are overcome; loosening, grinding and grading of materials are integrated in the same closed cavity; and therefore, environment pollution is avoided.
Description
Technical field
The utility model belongs to the pulverizer technical field, specifically relates to a kind of stagewise pulverizer.
Background technology
At present, domestic shredding, pulverizing to fibrous, sheet and granular material, generally adopt the multiple devices combinations such as pulverizer, grader, deduster and blower fan to carry out, namely first carry out shredding, pulverizing by pulverizer, then carried out the classification of granularity by grader, the satisfactory material of granularity enters deduster and gathers materials, and is undesirablely pulverized by pulverizer again.Adopt this mode that material is carried out shredding, pulverizes following shortcoming is arranged: one is the screen cloth with certain pore size because used grader adopts, is easy to cause machinery to stop up during practical application; In addition, when to fibrous or sheet material shredding, pulverizing, because the space three-dimensional size difference of material is larger, controls granularity with the screen cloth of round sieve or square sieve aperture and can cause the untrue of granularity, and needed elongated fibrous or slim sheet material has been screened out; Its two because what adopt is shredding, the pulverizing of many group multi-stags, thus take up room large, route length, inefficiency, waste energy, seriously polluted.
The utility model content
The utility model is for the problems referred to above, and what a kind of shredding that integrates material, pulverizing, classification were provided does not produce the stagewise pulverizer that machinery stops up.
For addressing the above problem, the stagewise pulverizer that provides comprises body, establishes crushing chamber in the body, places the reducing mechanism in the crushing chamber, and its design feature is: described reducing mechanism is the cyclone-type powder crushing device, places described crushing chamber below; The lower end of described crushing chamber has charging aperture door, upper end that discharging opening is arranged, and reducing mechanism is fixed on the interior power transmission shaft of described crushing chamber, and described power transmission shaft is by driven by motor, and described crushing chamber, electromechanization are individually fixed on the bearing support; The two ends of described power transmission shaft are fixed on the described bearing support through bearing, and an end is connected with described motor through belt pulley.
The discharge end of described crushing chamber top also is provided with the classification chamber, and the power transmission shaft in the described crushing chamber prolongs and runs through described classification chamber and is fixed on the described bearing support; Also be provided with the adjustable cyclonic blade on the power transmission shaft in described classification chamber.
Described crushing chamber is cylindricality; Described classification chamber is back taper; The discharging opening of the fixedly embedded described crushing chamber of the taper charging aperture in described classification chamber upper end, the top in described classification chamber is connected with the guide passage.
Import and the outlet of described guide passage are vertical configuration.
Operation principle of the present utility model is: material is in charging aperture is delivered to this bottom of device cylinder chamber, and the impact type whirlwind pulverizer that rotates through horizontal direction carries out shredding, pulverizing, in the eddy flow field that whirlwind type crushing machine forms, material greater than the control granularity will be accepted the impact type pulverization process in the cyclone outer, the material that reaches the control granularity requirements will enter cyclone center and gather materials through cylindricality crushing chamber discharging opening to deduster; In order to reach better grading effect, the utility model is provided with back taper classification chamber at the discharge end of cylindricality crushing chamber, and the power transmission shaft in this cavity is provided with the adjustable cyclonic blade; Carry out shredding through the whirlwind reducing mechanism, pulverize, material after scalping is processed will enter cyclone center in cylindricality crushing chamber discharging opening arrives the tapered grading chamber, the eddy flow field that is formed by the cyclone blade that arranges in this cavity carries out Screening Treatment again, namely carrying out the classification second time processes, meeting the material of controlling granularity requirements will be through the import of guide passage, being exported to deduster gathers materials, not conforming to the material of controlling granularity requirements moves downward with the inwall of cyclone along the tapered grading chamber, get back to and carry out pulverization process in the cylindricality crushing chamber, move in circles with this, thereby material is dissociated.
The position of cyclone blade described in the utility model on power transmission shaft is adjustable, its from the distance of the import of guide passage more close to, the granularity of the material of collecting is just less, otherwise, then larger; Therefore, this utility model can satisfy the requirement to difference control granularity.
The utility model has reduced screen cloth owing to adopt two stage cyclone formula piece-rate system, therefore, can not cause machinery to stop up, and has improved operating efficiency; The utility model efficient energy-saving, takes up room littlely because the shredding, pulverizing, the classification that integrate material are processed, and has overcome the shortcoming that multi-stag shredding, pulverizing, hierarchical processing method are organized in existing employing more; The utility model carries out owing to shredding, pulverizing, the classification of material are processed in the cavity that concentrates on a sealing, therefore, can not produce environmental pollution.
