Description

Technical Field

[0001] The utility model relates to the technical field of drying machines, in particular to a biomass energy particle drying machine. Background Art

[0002] A dryer is a device that removes moisture from materials by heating them. In the process of processing biomass energy pellets, a dryer is usually required to dry the raw materials. For example, wood chip pellets, straw pellets, and agricultural waste pellets all need to be dried to meet their specific usage requirements.

[0003] At present, the patent with the authorization publication number CN212747178U discloses a biomass energy pellet dryer, including a box, a first drying device is arranged on the top of the box, a first blower is fixedly installed on the top of the left side of the first drying device, a second blower is fixedly installed on the top of the right side of the first drying device, a limiting device is arranged on the top of the first drying device, a material guide port is arranged on the top of the limiting device, and a second drying device is arranged inside the box. Through the cooperation between the first blower and the second blower, the external wind is pressurized and sent to the inside of the box and the first drying device to dry the biomass, the box is set to limit the amount of biomass falling, and the excessive amount of biomass is prevented from causing incomplete drying of the biomass. The second drying device is set to perform secondary drying on the biomass and filter the impurities inside the biomass, and at the same time solves the problem of the biomass pellets being unable to be dried and causing mildew and agglomeration.

[0004] However, the following problems still exist in the current use of biomass energy pellet dryers:

[0005] When the above-mentioned device is in use, the particles are added directly from the feed port. During this process, some larger particles will directly enter the dryer, and these larger particles are very likely to be undried, thereby affecting the dryness of the entire particles. In addition, when the particles are added, because the particles contain a certain amount of dust, due to the large diameter of the feed port, a lot of dust will be raised, affecting the surrounding environment. Utility Model Content

[0006] In view of the shortcomings of the prior art, the utility model provides a biomass energy pellet dryer. By setting the feed port as a rotatable structure, the appropriate opening can be selected according to the different diameters of the feed pipe or the dumping bucket, thereby avoiding the occurrence of a large amount of dust being blown out. By adding a filter plate, particles with larger diameters can be filtered to avoid affecting the overall quality of the particles.

[0007] The utility model provides the following technical solution: a biomass energy pellet dryer, comprising a dryer shell, a feed pipe is penetrated through the left side of the dryer shell, and a discharge pipe is arranged on the right side of the dryer shell; a fixing screw is penetrated through the upper end of the feed pipe, and a dustproof component is arranged on the feed pipe, and a rotating component is arranged on the dustproof component.

[0008] Furthermore, the dustproof component includes a fixed plate and a positioning column. The fixed plate is interconnected with the inner surface of the feed pipe, and the fixed plate is interconnected with the positioning column. There are two positioning columns in total. Through the above structure, the filter plate can be positioned easily under the action of the positioning column.

[0009] Furthermore, the dust-proof component also includes a filter plate and a fixed cover plate, and the lower end of the filter plate and the upper end of the fixed plate are fitted together, and the filter plate is fitted together with the positioning column through the through positioning groove opened at the upper end thereof, the inner surface of the fixed cover plate and the outer surface of the feed pipe are fitted together, and the fixing screws are penetrated and arranged on the fixed cover plate. Through the above structure, it is convenient to filter the particles with larger diameters in the particles under the action of the filter plate, thereby avoiding insufficient drying of the particles.

[0010] Furthermore, the rotating assembly includes a fixed shaft, a vortex spring and a dust shield plate, and the fixed shaft is connected to the upper end of the fixed cover plate, and the fixed shaft is connected to the vortex spring, and the vortex spring is installed in a cylindrical mounting groove opened in the middle position of the dust shield plate. Through the above structure, the dust shield plate can be driven to return and rotate under the action of the vortex spring.

[0011] Furthermore, the rotating assembly also includes a rotating handle and a pushing plate, and the rotating handle is interconnected with the upper surface of the dust shield plate, and the lower end of the dust shield plate is interconnected with the pushing plate, and the pushing plate and the upper end of the filter plate fit together. Through the above structure, it is convenient to push large particle materials through the pushing plate to prevent large particle materials from clogging the grooves opened on the filter plate.

[0012] Furthermore, an arc-shaped through groove is provided at the upper end of the fixed cover plate. Through the above structure, it is convenient to add materials through the arc-shaped groove provided on the fixed cover plate.

[0013] Furthermore, the filter plate is provided with screening holes, and the filter plate is connected to the fixing screws through the threaded holes provided on its side. Through the above structure, the position of the filter plate can be fixed by the fixing screws.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] The biomass energy pellet dryer can achieve dust suppression when adding materials by arranging a fixed cover plate on the feed pipe, and can also choose to install or remove the fixed cover plate according to needs. The rotation of the fixed cover plate can drive the push plate to rotate, so that large particles at the filtration site can be pushed to the right side of the filter plate, which can effectively prevent the large particles from clogging the filter grooves on the filter plate, so as to improve the filtering effect of the filter plate, and the filter plate can be fixed by the filter plate to prevent the filter plate from moving up and down during use.

[0024] The filter plate 403 is placed inside the feed pipe 2, and the through positioning grooves provided on the filter plate 403 are fitted with the positioning columns 402, that is, the position of the filter plate 403 can be limited by the positioning columns 402, and then the fixed cover plate 404 is moved in the direction close to the feed pipe 2, and then the fixing screws 3 are passed through the grooves provided on the fixed cover plate 404 and the feed pipe 2, and then the fixing screws 3 are rotated, and at this time the fixing screws 3 begin to be connected with the threaded holes provided on the filter plate 403, so that the position of the filter plate 403 can be fixed to avoid the movement of the filter plate 403 during use, and then the biomass energy particle raw materials can be added to the feed pipe 2, and under the action of the filter plate 403, larger particles can be filtered, and particles of qualified size enter the dryer housing 1 through the lower end of the feed pipe 2 (a heating component and a spiral feeding structure are provided inside the dryer housing 1, and its structure and function are consistent with those of the existing spiral feeding dryer), and the dried particles are discharged through the right end pipe of the dryer housing 1;

[0025] A rotating assembly 5 is provided on the dustproof assembly 4; the rotating assembly 5 includes a fixed shaft 501, a vortex spring 502 and a dust shield plate 503, and the fixed shaft 501 is connected to the upper end of the fixed cover plate 404, and the fixed shaft 501 is connected to the vortex spring 502, and the vortex spring 502 is installed in a cylindrical installation groove opened in the middle position of the dust shield plate 503; the rotating assembly 5 also includes a rotating handle 504 and a push plate 505, and the rotating handle 504 is connected to the upper surface of the dust shield plate 503, and the lower end of the dust shield plate 503 is connected to the push plate 505, and the push plate 505 is fitted with the upper end of the filter plate 403;
