Description

Technical Field

[0001] The utility model relates to the technical field of RDF fuel rod production, in particular to a RDF fuel rod raw material grading and crushing mechanism. Background Art

[0002] RDF fuel rod is a fuel rod made from a mixture of solid waste and recyclable materials. RDF fuel rod is usually made from a mixture of daily raw materials, waste paper, waste plastic and waste wood. After treatment and processing, it becomes solid fuel to replace traditional fossil fuels such as coal and oil.

[0003] In the production and processing of RDF fuel rods, a graded crushing mechanism is required to crush the collected raw materials. For example, Chinese patent CN211026651U discloses a crusher with a graded crushing function. The crusher can complete the graded crushing operation through a first crushing box and a second crushing box installed on a frame, and can complete the graded processing operation of the raw materials through a first collecting hopper and a material blocking mechanism installed at the bottom of the first crushing box, and can export the raw materials through the material blocking mechanism and the baffle to reduce energy consumption. However, the raw materials are easily left inside the crusher during processing, resulting in a waste of raw materials. Therefore, we propose a graded crushing mechanism for raw materials of RDF fuel rods. Utility Model Content

[0004] The utility model aims to provide a RDF fuel rod raw material classification crushing mechanism, which is convenient for cleaning and can discharge all the raw materials to save the raw materials.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: an RDF fuel rod raw material grading and crushing mechanism, comprising four supporting columns distributed in a rectangular shape, two crushing frames installed on the supporting columns and a crushing assembly installed in the crushing frames, a screening assembly located between the two crushing frames is installed on the supporting columns, a driving assembly for driving the screening assembly to vibrate is also provided between the two supporting columns on the left side, a cleaning assembly is provided in the crushing frame, a transmission assembly for moving the cleaning assembly is provided between the two supporting columns on the left side, and a belt is connected between the transmission assembly and the driving assembly.

[0006] By adopting the above technical solution, the crushing components in the upper and lower crushing frames perform graded crushing processing on the collected raw materials. After the processing is completed, the driving component is started, so that the screening component can screen the raw materials of different diameters, and the unqualified materials will continue to return to the upper crushing frame for crushing. During the screening process, the screening component uses a belt to drive the transmission component to rotate. When the transmission component rotates, the cleaning component moves in the crushing frame to clean the raw materials attached to the crushing component, so as to facilitate the discharge of all the raw materials in the crushing frame and avoid waste of raw materials.

[0007] The utility model is further configured as follows: the crushing assembly includes two crushing rollers rotatably connected to the crushing frame, a synchronous belt drivingly connecting the two crushing rollers, and a motor installed on the crushing frame for driving one of the crushing rollers to rotate.

[0008] By adopting the above technical solution, the motor starts to drive one of the crushing rollers to rotate, and when the crushing roller rotates, the other crushing roller is driven to rotate through the synchronous belt, so that the two crushing rollers rotate at the same time to crush the raw materials.

[0009] The utility model is further configured as follows: the distance between the two upper crushing rollers is greater than the distance between the two lower crushing rollers.

[0010] By adopting the above technical solution, graded crushing of raw materials is achieved, and materials with different diameters can be processed.

[0014] By adopting the above technical solution, the material crushed by the upper crushing roller falls on the screen frame for screening, and the qualified material falls into the lower crushing frame for further crushing. The receiving frame can collect the unqualified material and pour it back into the upper crushing frame for re-crushing.

[0015] The utility model is further configured as follows: the driving assembly includes a rotating motor installed on the support column, a rotating rod fixedly connected to the output shaft of the rotating motor and rotatably connected to another support column, and a push plate installed outside the rotating rod.

[0016] By adopting the above technical solution, the rotating motor is started to drive the rotating rod to rotate, so that the rotating rod on the rotating rod can intermittently contact the screen frame. When the rotating rod and the screen frame are in contact and separation, the spring is compressed or bounced open, so that the screen frame can swing left and right, thereby improving the screening effect of the screen frame.

[0017] The utility model is further configured as follows: the cleaning assembly includes a guide rod installed on the inner side of the crushing frame, a screw rod rotatably connected to the inner wall of the crushing frame and with one end extending to the left side of the crushing frame, and a brush plate threadedly connected to the outside of the screw rod and sleeved on the outside of the guide rod.

[0021] The utility model is further configured as follows: the belt transmission connects the rotating shaft and the rotating rod.

[0022] By adopting the above technical solution, when the rotating motor starts to drive the rotating rod to rotate, the rotating rod uses the belt to drive the rotating shaft to rotate. At this time, bevel gear one rotates with the rotating shaft. Because bevel gear one is meshed with bevel gear two, the screw rod is driven to rotate, so that the brush plate moves left and right in the crushing frame to clean the raw materials attached to the crushing roller, which is convenient for discharging all the raw materials in the crushing frame and avoiding waste of raw materials.

[0023] The beneficial effect of the utility model is that the crushing components in the upper and lower crushing frames crush the collected raw materials. After the processing is completed, the driving component is started, so that the screening component can screen the raw materials of different diameters. Unqualified materials will continue to return to the upper crushing frame for crushing. During the screening process, the screening component uses a belt to drive the transmission component to rotate. When the transmission component rotates, the cleaning component moves in the crushing frame to clean the raw materials attached to the crushing component, which is convenient for discharging all the raw materials in the crushing frame and avoiding waste of raw materials.
