Description

Technical Field

[0001] The utility model belongs to the technical field of auger, in particular to a material sealing auger. Background Art

[0002] Steam is an essential parameter in the pelleting process of the pellet mill. Steam will affect the heating and softening of the material, thereby improving the plasticity of the feed and reducing the pelleting cost. However, during the pelleting process, steam is easy to flow back into the material sealing auger, causing the material in the material sealing auger to stick or agglomerate. The material sealing auger is an important part of the mill's wind network system. If the wind network leaks, it will directly affect the mill's output.

[0003] Therefore, there is an urgent need for a material sealing auger that can simultaneously realize the conveying function under the pulverizer and the feeding function on the granulator. Utility Model Content

[0004] The utility model aims to provide a material sealing auger which can prevent air leakage of the wind net during the crushing process and steam backflow during the granulation and feeding process.

[0005] The purpose of the utility model is achieved as follows: a material-sealing auger, comprising an auger shaft and a conveying pipe, and also comprising a material-sealing discharge device, the conveying pipe comprising a feed section, a front conveying section, a material-sealing section, a rear conveying section and a discharge section which are arranged in sequence from left to right, the outer periphery of the auger shaft is provided with front spiral blades corresponding to the feed section and the front conveying section, the outer periphery of the auger shaft is provided with rear spiral blades corresponding to the rear conveying section, the feed end of the material-sealing discharge device is connected with the material-sealing section, and the discharge section of the material-sealing discharge device is connected with the discharge section.

[0006] When the utility model is used, the crushed material enters the feeding section, is gathered and conveyed backwards under the push of the front spiral blades, until it accumulates at the blade discontinuity (i.e., the sealing section) to form a material seal, and then, under the push of the rear spiral blades, most of the material that plays the role of sealing is released and discharged through the discharging section. At the same time, the material seal discharging device works to release the small part of the material that plays the role of sealing and conveys it to the discharging section for discharge. Compared with the prior art, the beneficial effects of the utility model are: the gaps between materials are reduced by the material sealing section, and the formed material seal plays a role in blocking air and preventing steam backflow during the material transportation and granulation feeding process after the pulverizer, thereby improving the pulverizing efficiency of the pulverizer; compared with the single discharge structure in the prior art, a material seal discharge device is added to the material sealing section, so the efficiency of material seal release and discharge efficiency can be improved, and the material can be smoothly discharged from the discharge section through two discharge paths, thereby avoiding the arching phenomenon of the material in the granulator feeding hopper; the material seal discharge device can also discharge the material remaining between the spiral blade and the gap of the conveying pipe in time, avoiding waste and improving material utilization.

[0007] As a further improvement of the present invention, the material sealing discharge device includes a discharge motor and a discharge housing, the output end of the discharge motor is coaxially provided with a discharge auger through a coupling, the front end of the discharge housing is connected to the material sealing section through a discharge port, and the rear end of the discharge housing is connected to the discharge section.

[0008] As a further improvement of the utility model, one end of the auger shaft is connected to the driving assembly, and the other end of the auger shaft is connected to the conveying pipe through a supporting assembly.

[0009] As a further improvement of the utility model, it is characterized in that the driving assembly includes a driving motor and a transmission mechanism, the output end of the driving motor is coaxially arranged with the input end of the transmission mechanism, and the output end of the transmission mechanism is coaxially arranged with the auger shaft.

[0010] As a further improvement of the utility model, the support assembly includes an end cover arranged at the discharge section, and a rolling bearing is arranged between the end cover and the auger shaft.

[0011] As a further improvement of the present invention, the conveying pipe further comprises a feed port and a discharge port, wherein the feed port is arranged above the feed section, and the discharge port is arranged below the discharge section.

[0012] As a further improvement of the present invention, the feed section is coaxially arranged with the front conveying section through a connecting flange, the front conveying section, the material sealing section and the rear conveying section are coaxially arranged as a whole, and the rear conveying section is coaxially arranged with the discharge section through a connecting flange.
