Description

Technical Field

[0001] The invention relates to the technical field of alternative fuel screening, and in particular to an alternative fuel drum screening device with an automatic lifting and separation function. Background Art

[0002] In order to reduce carbon emissions, the application of alternative fuels is gradually emerging. These alternative fuels not only help reduce dependence on a single energy source, but also improve the security and stability of energy supply. Biomass fuels, industrial solid waste, domestic garbage and other types of waste are important sources of alternative fuels; in the production process, biomass fuels are usually processed into granular products, but the finished products often contain a certain amount of fine impurities, so they need to be further processed by a drum screening device to remove these impurities. However, traditional drum screening equipment has some shortcomings: the operator must manually add the material to be screened into the drum, which is not only time-consuming and labor-intensive, but also inefficient; in addition, when the qualified products after screening reach a certain amount, they need to be collected manually regularly, and the whole process is cumbersome and labor-intensive.

When screening, the motor at one end of the control rod 503 is started, and the motor drives the control rod 503 to rotate. Since the surface of the control rod 503 is rotatably connected with the rotating rod 505 through the gear belt 504, and the rotating rod 505 rotates with the threaded rotating rod 506 through the bevel gear assembly, the threads on the surface of the threaded rotating rod 506 control the lifting plate 507 to slide upward, and the lifting plate 507 and the top plate 508 slide upward and push the sliding ejection plate 408 to slide upward, so that the top of the rolling screen drum 303 is opened, and the connecting slide rod 40 3 slides, the spring on the surface of the connecting slide rod 403 contracts, the sliding ejector plate 408 continues to slide and contacts with the contact rod 7032, the contact rod 7032 and the baffle plate 7033, the top sealing plate 7034 slide upward, the top sealing plate 7034 is separated from the discharge port of the storage barrel 701, the alternative fuel particles fall into the auxiliary docking plate 602 and pass through the area between the sliding ejector plate 408 and the auxiliary docking plate 602 and fall into the storage barrel 701, and the feeding operation is automatically completed.

After a certain amount of injection, the control rod 503 rotates in the opposite direction, and the sliding ejector plate 408 slides downward to return to its original position. The rolling screen drum 303 is blocked, and then the motor at one end of the support rod 301 is controlled to start. The motor controls the rolling screen drum 303 to rotate through the support rod 301. During the rotation, the replacement fuel is screened. Since the brush group frame 603 is in contact with the surface of the rolling screen drum 303, the rolling screen drum 303 can be cleaned to avoid clogging of the mesh. After the screening is completed, the motor at one end of the control rod 503 is restarted to start. The control rod 503 rotates in the opposite direction, and the top plate 508 slides downward, pushing the bottom set of sliding ejection plates 408 to slide downward, and the bottom set of connecting slide rods 403 slide downward. The surface spring of the connecting slide rod 403 contracts, and the connecting slide rod 4 03 During the sliding process, it will contact the inclined surface of the push plate 406, continue to slide and push the sliding plate 405 and the push plate 406 to slide to one side, the spring contracts, the sliding plate 405 slides and squeezes the start button 407, and since the start button 407 is electrically connected to the motor at one end of the rotating rod 201, the rotating rod 201 rotates and controls the rotation of the conveying plate 202, and the inclined surface is changed. The other side of the conveying plate 202 rotates and slides to the bottom of another group of discharge slots 102. After the bottom of the rolling screen drum 303 is opened, the alternative fuel rolls out of the rolling screen drum 303 and rolls along the conveying plate 202 and the discharge slot 102 into the pre-placed load, completing the transportation.
