Description

Technical Field

[0001] The utility model relates to the technical field of extruders, in particular to a rod-shaped fuel extruder. Background Art

[0002] The coal rod machine, also known as the coal rod extruder, mainly consists of a machine base, a bearing seat, a screw shaft, a cylinder, a discharge port, and a coal rod mold. The coal rod machine uses the principle of screw extrusion to compress the modulated pulverized coal into a coal rod of a predetermined shape with a certain strength. It is widely used in the molding of raw materials such as coal powder, coal foam, coal gangue, coking coal, lignite, anthracite, iron powder, and aluminum powder.

[0003] The patent with publication number CN 220294855 U discloses a carbon rod extruder, which includes an extruder body, a feeding pipe fixedly connected to the top of the extruder body, a storage hopper fixedly connected to the top of the feeding pipe, and a driving motor installed on the outside of the feeding pipe. The device can drive the crushing roller to continuously contact the carbon rod raw material by driving the rotation of the shaft rod to refine it, thereby making the specifications of the carbon rod raw material entering the extruder body more uniform, thereby improving the subsequent carbon rod forming effect. However, the device has the problem of directly pouring the carbon rod raw material into the storage hopper, and then being crushed by the internal rotating crushing roller and falling into the extruder body, but the rotation of the crushing roller is carried out by a vertical transmission composed of a plurality of crushing bevel gears, and the main transmission structure is located in the feeding pipe of the crushed raw material, which may cause the raw material debris to splash into the transmission structure during the raw material crushing process to damage it, thereby reducing the service life of the internal structure of the extruder. For this reason, a rod-shaped fuel extruder is proposed to solve the problem of accelerated aging of the internal structure of the existing extruder due to the uneven quality of the raw materials.
