The utility model is for solving the problems of the technologies described above, the technical scheme providing is: a kind of mill feeding elbow, comprise changeover portion for connecting charging gear and entrance linkage section for being connected grinding machine feeding mouth, described changeover portion and entrance linkage section are integrative-structure in a certain angle, and pass through arc transition between changeover portion and entrance linkage section, on the top tube wall of described changeover portion, be provided with a unlimited liner and lay mouth, liner is laid a mouthful place and is provided with the shrouding removably connecting, on the lower inner wall face of described elbow, be provided with wear-resistant liner, between this wear-resistant liner 5 and the tube wall of elbow, be bolted, and one end of bolt is embedded in the inside of wear-resistant liner.
One end that described entrance linkage section is connected with changeover portion is also provided with an auxiliary material inlet pipe being connected with elbow inside.
Described entrance linkage section is provided with the sealing ring matching with the end face of grinding machine feeding mouth.
On madial wall below described entrance linkage section is positioned at, be provided with vertically many reinforcements.
Angle between described entrance linkage section and changeover portion is 90 ° ~ 180 °.
Described shrouding is connected with the tube wall of changeover portion with bolt by hinge respectively along the two ends of changeover portion circumferencial direction.
Described wear-resistant liner is polymer composite.
The beneficial effects of the utility model:
1, mill feeding elbow of the present utility model, rational in infrastructure, with low cost, easy to use.The bottom of charging elbow is provided with wear-resistant liner, has increased the wearability of charging elbow entirety, has slowed down the impact of material for charging elbow, has extended the service life of charging elbow entirety.Simultaneously, between wear-resistant liner in charging elbow and the metal shell of elbow, adopt the mode removably connecting, after wear-resistant liner consumption, can directly open the shrouding arranging on changeover portion changes wear-resistant liner, repair time and device cost are saved, improve the production efficiency of grinding machine, be conducive to avoid waste that discarded elbow causes and the pollution of environment.
2, mill feeding elbow of the present utility model, between entrance linkage section and the end face of grinding machine feeding mouth sealing ring the sealing effectiveness that has improved grinding machine is set, avoided mill feeding mouth to leak the generation of material phenomenon, meanwhile, also extended the service life of grinding machine.
3, mill feeding elbow of the present utility model, many reinforcements that arrange vertically on entrance linkage section madial wall have further strengthened wearability and the mechanical strength of charging elbow entrance linkage section, extend the service life of charging elbow, grinding machine can continuous charging, is conducive to the continuous industrial production running of grinding machine.
4, mill feeding elbow of the present utility model, the setting of changeover portion upper sealing plate, can there is the faults such as wearing and tearing or obstruction at charging elbow time, facilitates replacing and the investigation maintenance of charging elbow inside.
5, mill feeding elbow of the present utility model, the setting of one end auxiliary material inlet pipe that entrance linkage section is connected with changeover portion, can facilitate some production lines that need increase auxiliary material for the increase of auxiliary material and evenly mix, the arranging of entrance linkage section end auxiliary material inlet pipe can also be used for charging elbow washing away and safeguarding while stopping up.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Reference numeral: 1, changeover portion, 2, entrance linkage section, 3, shrouding, 4, auxiliary material inlet pipe, 5, wear-resistant liner.
Detailed description of the invention
Below in conjunction with brief description of the drawings detailed description of the invention of the present utility model:
A kind of mill feeding elbow, comprise changeover portion 1 for connecting charging gear and entrance linkage section 2 for being connected grinding machine feeding mouth, described changeover portion 1 and entrance linkage section 2 are integrative-structure in a certain angle, and pass through arc transition between changeover portion 1 and entrance linkage section 2, on the top tube wall of described changeover portion 1, be provided with a unlimited liner and lay mouth, liner is laid a mouthful place and is provided with the shrouding 3 removably connecting, on the lower inner wall face of described elbow, be provided with wear-resistant liner 5, between this wear-resistant liner 5 and the tube wall of elbow, be bolted, and one end of bolt is embedded in the inside of wear-resistant liner 5.
