Abstract
The utility model relates to the technical field of pelletizers, particularly to a pelletizer hopper with a preheating function. A feeding pipe is arranged at the top of the hopper, a discharge pipe which is used for connecting an extruder barrel body is arranged at the bottom of the hopper, a helical coil pipe is arranged on the inner wall of the hopper, and two ends of the coil pipe stretch out from the side wall of the hopper and are connected with an steam inlet pipe and a steam outlet pipe respectively. According to the pelletizer hopper with the preheating function, a preheating device is arranged in the hopper, and the coil pipe is directly exposed to the hopper, therefore, the preheating uniformity is improved, the electric energy loss is reduced, and the production efficiency is improved. A buffering hopper is of a circular truncated cone shape which is big at the top and small at the bottom, the discharge pipe is of a frustum shape which is big at the top and small at the bottom, therefore, the material can slowly fall down and the preheating effect is improved; a material feeding diffusion hopper is arranged between the top part of the hopper and the feeding pipe and is of the frustum shape which is small at the top and big at the bottom, and therefore, the material is fully dispersed when entering the hopper and cannot be gathered together.
Description
Technical field
The utility model relates to comminutor technical field, specifically a kind of comminutor hopper with preheat function.
Background technology
Existing extruder, because its hopper is only as the effect of charging, cannot plays the function of preheating, thereby cause material in comminutor, to heat, and the time-consuming electricity that takes, is unfavorable for energy-conserving and environment-protective.
Along with scientific and technological progress, preheating device while there is steam pipe coil in the hopper of part comminutor, finds through long-term practice, and this kind of comminutor hopper also exists the phenomenons such as preheating is inhomogeneous, has a strong impact on the quality of product.
Utility model content
For the technical problem existing in prior art; the utility model provides a kind of comminutor hopper with preheat function; by design preheating device in hopper; simultaneously; make preheat coil directly exposed in hopper; both improved the uniformity of preheating, and made again electric energy loss be reduced, enhanced productivity.
To achieve these goals; the technical scheme that the utility model adopts is: a kind of comminutor hopper with preheat function; comprise hopper; the top of hopper is provided with feed pipe; bottom is provided with the discharge nozzle for connecting extruder cylindrical shell; described hopper inwall is provided with spiral coil pipe, and the two ends of described coil pipe are stretched out and connected respectively steam inlet tube and steam from hopper side wall and go out pipe.
Further, the outer wall of described coil pipe be provided with some for dispel the heat, be criss-cross fin.
Further, be provided with horizontally disposed shaft in described hopper, described shaft is provided with screw mixing blade.
Further, one end of described shaft is connected with the motor of being located at hopper outside, and the other end is connected with the axle sleeve of being located at hopper outside.
Further, the big up and small down frustum of described discharge nozzle.
Further, between the bottom of described hopper and discharge nozzle, be provided with buffering bucket.
Preferably, big up and small down round table-like of described buffering bucket.
Further, between the top of described hopper and feed pipe, be provided with charging diffusion bucket.
Preferably, described charging diffusion bucket is up-small and down-big frustum.
The comminutor hopper with preheat function of the present utility model, compared with prior art, its beneficial effect shows:
The comminutor hopper with preheat function of the present utility model, by design preheating device in hopper, meanwhile, makes coil pipe directly exposed in hopper, has both improved the uniformity of preheating, makes again electric energy loss be reduced, and enhances productivity.The outer wall of coil pipe be provided with some for dispel the heat, be criss-cross fin, can further improve heat-transfer effect.In hopper, be provided with horizontally disposed shaft, shaft is provided with screw mixing blade, can be convenient to the uniformity of material preheating.One end of shaft is connected with the motor of being located at hopper outside, and the other end is connected with the axle sleeve of being located at hopper outside, can make stirring system can realize better running.Between the bottom of hopper and discharge nozzle, be provided with buffering bucket, can further prevent that material time of staying in hopper is too short, and the unequal phenomenon of being heated causing occurs.Big up and small down round table-like of buffering bucket, meanwhile, the big up and small down frustum of design discharge nozzle.Thereby material can slowly be fallen, improved the effect of preheating.Meanwhile, the utility model is provided with charging diffusion bucket between the top of hopper and feed pipe.Charging diffusion bucket is up-small and down-big frustum.By this kind of structural design, in the time of can making material enter hopper, can fully disperse, can not produce gathering.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
For the ease of it will be appreciated by those skilled in the art that below in conjunction with accompanying drawing, the utility model is further described.
As a kind of preferred embodiment of the present utility model; refer to Fig. 1; a kind of comminutor hopper with preheat function; comprise hopper 6; the top of hopper 6 is provided with feed pipe 9; bottom is provided with the discharge nozzle 13 for connecting extruder cylindrical shell, and hopper 6 inwalls are provided with spiral coil pipe 1, and the two ends of coil pipe 1 are stretched out and connected respectively steam inlet tube 4 and steam from hopper 6 sidewalls and go out pipe 10.By design preheating device in hopper, meanwhile, make coil pipe directly exposed in hopper, both improved the uniformity of preheating, make again electric energy loss be reduced, enhance productivity.
In order further to improve heat-transfer effect, the outer wall of coil pipe 1 be provided with some for dispel the heat, be criss-cross fin 7.
For the ease of the uniformity of material preheating, in hopper 6, be provided with horizontally disposed shaft 3, shaft 3 is provided with screw mixing blade 2.
For stirring system can be realized better running, one end of shaft 3 is connected with the motor 11 of being located at hopper 6 outsides, and the other end is connected with the axle sleeve 5 of being located at hopper 6 outsides.
Too short in order further to prevent material time of staying in hopper, and the unequal phenomenon of being heated of causing occurs, between the bottom of hopper 6 and discharge nozzle 13, be provided with buffering bucket 12.
As preferably, big up and small down round table-like of buffering bucket 12, meanwhile, the big up and small down frustum of design discharge nozzle 13.Thereby material can slowly be fallen, improved the effect of preheating.
