Abstract
The utility model relates to a hammer mill with secondary crushing groove structure; a crushing chamber composed of a screen and a pressure screen frame plate is fixedly arranged on the base of the hammer mill, the top end of the screen is provided with a material inlet, a guide plate is arranged on the material inlet in the crushing chamber, a rotary shaft is rotationally erected on the inner and outer wall bodies of the crushing chamber, a rotary plate is fixed on the rotary shaft, a hammer is fixed on the rotary plate, the screen is shaped like a water drop in the axial direction of rotary shaft, a through hole penetrates through the wall body of the screen is machined on the bottom end of the inner wall of the screen along the axial direction of rotary shaft, a tray with groove-shaped end surfaces is erected on the wall body of screen on both sides of the through groove, a reversing body is arranged in the groove body of the tray, the width of the reversing body gradually decreases from bottom to top. The hammer mill with secondary crushing groove structure not only can increase resistance and reduce running speed of material, but also can change the running direction of material so that the tangent running direction of material is changed and the material can move along the circular center inner side direction; the crushing performance of hammer mill is further improved.
Description
Technical field
The utility model relates to a kind of hammer crusher, especially a kind of hammer crusher with secondary crushing groove structure.
Background technology
In prior art, the secondary of hammer crusher pulverize structure by no grooved structural development to trench structure is arranged.Develop into dual-trench type (two groove) by single grooved (groove) again.More than three kinds of secondaries pulverize structural shapes though the effect that slows down material movement speed all arranged, can increase hammer leaf relative velocity and dynamics when hitting material, can play a role to improving crushing effect.But certain space length is arranged because hammer leaf end and secondary are pulverized between the structure, hammer leaf can only hit the material that exceeds this distance and pulverize, to this distance within material still hit less than, therefore also can't to this partly material carry out pulverizing second time, so that the secondary crushing effect can't be said so is very good.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of and not only can increase resistance, slow down material movement speed, and can change the direction of material movement, making the material movement direction be changed into along side direction in the center of circle by original tangential direction moves, make hammer leaf can hit the material that all need be pulverized fully at the volley, thereby can further improve the smashing capability of hammer crusher, the hammer crusher that the secondary crushing effect is more desirable with secondary crushing groove structure.
The technical scheme that provides according to the utility model, described hammer crusher with secondary crushing groove structure, comprise the hammer crusher support, on the hammer crusher support, be fixed with the pulverizing chamber that forms by sieve sheet and pressure screen frame plate, sieve sheet top has material inlet, material inlet place in pulverizing chamber is provided with deflector, rotating turret is provided with rotating shaft on the inside and outside wall body of pulverizing chamber, in rotating shaft, be fixed with rotating disk, on rotating disk, fix some hammer leaves, described sieve sheet is water droplet shape on the axis direction of rotating shaft, offer along the shaft axis direction in sieve sheet inwall bottom and penetrate the groove of sieve sheet wall body, on the sieve sheet wall body on described groove both sides, set up end face supporting plate in the form of slot, be fixed with support bar at the hammer crusher support, the groove bottom of supporting plate is seated at this supporting bar top portion, is provided with the changed course body in the cell body of supporting plate, and described changed course body width shrinks from lower to upper gradually.
Described changed course body section is herringbone or triangle.The cell body partial width of described supporting plate shrinks from top to bottom gradually.
The utility model not only can increase resistance, slow down material movement speed, and can change the direction of material movement, making the material movement direction be changed into along side direction in the center of circle by original tangential direction moves, make hammer leaf can hit the material that all need be pulverized fully at the volley, thereby can further improve the smashing capability of hammer crusher.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present utility model.
Fig. 2 is the secondary crushing groove structure enlarged drawing in the utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in the figure: the utility model mainly is made of hammer crusher support 1, sieve sheet 2, pressure screen frame plate 3, deflector 4, rotating shaft 5, rotating disk 6, hammer leaf 7, supporting plate 8, changed course body 9 and support bar 10 etc.
This has the hammer crusher of secondary crushing groove structure, comprise hammer crusher support 1, on hammer crusher support 1, be fixed with the pulverizing chamber that forms by sieve sheet 2 and pressure screen frame plate 3, sieve sheet 2 tops have material inlet, material inlet place in pulverizing chamber is provided with deflector 4, rotating turret is provided with rotating shaft 5 on the inside and outside wall body of pulverizing chamber, in rotating shaft 5, be fixed with rotating disk 6, on rotating disk 6, fix some hammer leaves 7, described sieve sheet 2 is water droplet shape on the axis direction of rotating shaft 5, offer along rotating shaft 5 axis directions in sieve sheet 2 inwall bottoms and penetrate the groove of sieve sheet 2 wall bodies, on sieve sheet 2 wall bodies on described groove both sides, set up end face supporting plate in the form of slot 8, be fixed with support bar 10 at hammer crusher support 1, the groove bottom of supporting plate 8 is seated at this support bar 10 top ends, be provided with changed course body 9 in the cell body of supporting plate 8, described changed course body 9 width shrink from lower to upper gradually, and body 9 sections that promptly alter course are " people " font, triangle or curved surface shaped.
Described changed course body 9 sections are herringbone.The cell body partial width of described supporting plate 8 shrinks from top to bottom gradually.
The operation principle of the present utility model and the course of work:
In the hammer crusher is proal with the high speed circular movement pattern along circle in the sieve sheet 2 by comminuting matter in pulverizing chamber.Large granular materials is because quality is big, centrifugal force is also big, be close to sieve sheet 2 inboards and travel forward so can produce, and small particles material is because quality is little, centrifugal force is also little, can only be in the internal layer motion of logistics, and this phenomenon is called as the circulation layer phenomenon.This phenomenon is totally unfavorable to pulverizing, and is on the one hand to make its fragmentation because be not easy to hit large granular materials in hammer leaf 7 motions, is that small particles material does not reach the chance that sieve sheet 2 has reduced the sieve aperture that passes sieve sheet 2 in the internal layer motion on the other hand.The utility model will destroy the circulation layer phenomenon exactly, the large granular materials that to be close to the compass screen surface motion is subjected to resistance through this changed course body 9 time, this resistance lowers the movement velocity of material on the one hand, the main direction that also can change material movement, make the material movement direction change into along changed course body 9 sidewalls side direction in the pulverizing chamber center of circle and move, the hammer leaf end can be made things convenient for hit these materials timely and it is smashed by original tangential direction.While also makes small particles material also can in time touch the compass screen surface of sieve sheet 2 and passes outside the sieve aperture discharge machine.
