Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of drying equipment, in particular to drying equipment for biomass fuel production. Background Art
[0002] Biomass fuel is a solid fuel made from various biomass materials (such as wood chips, straw, hemp stalks, corn stalks, etc.) that are compressed by processing and forming equipment. Due to the high water content in biomass materials, the water will occupy part of the space during the fuel forming process, thereby reducing the density and calorific value of the solid fuel and affecting its combustion efficiency. Therefore, in the production of biomass fuel, a drum dryer is often used to dry the material to remove the water in the biomass fuel, increase its density and calorific value, and thus improve storage, transportation efficiency and combustion efficiency;
[0003] At present, when the existing drum dryer is in use, a large amount of materials inside it will accumulate at the bottom, causing the bottom layer to be overheated while the materials in the middle and upper layers cannot be fully heated in time, resulting in uneven drying operation, affecting the quality and reducing work efficiency.
[0004] In order to solve the above problems, this application proposes a drying device for biomass fuel production. Utility Model Content

[0007] The utility model is a drying device for biomass fuel production, comprising a drum dryer, wherein a paddle for driving materials to be lifted is arranged inside the drum dryer, and the paddle is also used to diffuse the area of contact between materials and heat, bases for limiting the paddle at a predetermined position are arranged inside both ends of the drum dryer, an outer ring frame for driving the paddle to rotate is arranged above the base, a side bracket is also arranged above one side of the base, a scraper for scraping the inner surface of the drum dryer to prevent the material residue from forming dirt is arranged at one end of the side bracket, a limiting shaft is arranged at one end of the side bracket, and a crushing nail for crushing agglomerated materials is arranged on the outside of the limiting shaft.
[0008] Furthermore, a positioning groove is provided inside the shifting plate for small-sized materials to scatter downward to prevent large-sized materials from piling up. The positioning groove separates the small-sized materials to increase their heating area.
[0009] Furthermore, a rotating cam is rotatably mounted on one side of the upper end of the side bracket, and a blocking sleeve is arranged on the outer side of one end of the rotating cam for resisting against the inner wall of the upper end of the drum dryer, and the blocking sleeve is also used to drive the side bracket to rotate.
[0010] Furthermore, a transmission gear is arranged on the outer side of the other end of the side bracket for meshing and connecting with the protruding toothed structure on the outer side of the outer ring frame.
[0011] Furthermore, a ball bearing for reducing frictional resistance is installed at the bottom of the base, and the ball bearing cooperates with the gravity of the base to keep the base in a vertically upward position.
[0012] Furthermore, guide slopes for guiding materials to the middle area are arranged on the inner sides of both ends of the drum dryer.
[0013] Furthermore, a connecting rod is provided at the end of the shift plate for fixedly connecting to a side surface of the outer ring frame.
[0014] The utility model has the following beneficial effects:
[0015] The utility model assembles the paddle plate inside the drum dryer, and can paddle the material to make it outside through the scraper during the drying operation, so as to prevent a large amount of material from being accumulated at the bottom. Compared with the existing drying equipment, the utility model can conveniently perform timely and sufficient heating and drying treatment on a large amount of material, improve its drying efficiency, prevent the occurrence of uneven heating to ensure the drying quality, and is conducive to the use of large-scale biomass fuel drying operations;

[0027] See also Figure 1-4 As shown, the utility model is a drying equipment for biomass fuel production, including a cylinder dryer 1, a paddle 2 for driving the material to be lifted is arranged inside the cylinder dryer 1, and the paddle 2 is also used to diffuse the area of contact between the material and the heat. Bases 3 for limiting the paddle 2 to a predetermined position are arranged inside both ends of the cylinder dryer 1, an outer ring frame 4 for driving the paddle 2 to rotate is arranged above the base 3, and a side bracket 5 is also arranged above one side of the base 3. A scraper 6 for scraping the inner surface of the cylinder dryer 1 to prevent the material from remaining and forming dirt is arranged at one end of the paddle 2, and a limiting shaft 8 is arranged at one end of the side bracket 5. A crushing nail 9 for crushing the agglomerated material is arranged on the outer side of the limiting shaft 8. In this embodiment, the scraper 6 is used to prevent part of the material from sticking to the inner wall surface of the cylinder dryer 1.
[0028] Among them, a positioning groove 7 is opened inside the paddle 2 for small-sized materials to scatter downward to prevent large-sized materials from accumulating. The positioning groove 7 separates the small-sized materials to increase their heating area. In this embodiment, the positioning groove 7 is used to pre-discharge small-sized materials to form a separation effect.
[0029] Among them, a rotating cam 10 is rotatably installed on one side of the upper end of the side bracket 5, and a blocking sleeve 11 is provided on the outer side of one end of the rotating cam 10 for resisting against the inner wall of the upper end of the drum dryer 1. The blocking sleeve 11 is also used to drive the side bracket 5 to rotate. In this embodiment, the blocking sleeve 11 is used to increase the friction resistance, so that when the drum dryer 1 rotates, the blocking sleeve 11 can be driven to rotate by the friction resistance.
[0030] A transmission gear 12 is disposed on the outer side of the other end of the side bracket 5 for meshing with the protruding toothed structure on the outer side of the outer ring frame 4 . In this embodiment, the diameter of the transmission gear 12 is smaller than the diameter of the blocking sleeve 11 .
[0031] Among them, a ball 13 for reducing friction resistance is installed at the bottom of the base 3. The ball 13 cooperates with the gravity of the base 3 to keep the base 3 in a vertical upward position. In this embodiment, the ball 13 is used to prevent the drum dryer 1 from driving the base 3 to deflect.
[0032] Among them, guide slopes 14 for guiding materials to the middle area are arranged on the inner sides of both ends of the drum dryer 1. In this embodiment, the guide slopes 14 are used to prevent materials from piling up at the two ends.
[0033] Among them, a connecting rod 15 is provided at the end of the shift plate 2 for fixedly connecting with a side surface of the outer ring frame 4 .
[0034] It can be understood that the utility model can conveniently disperse the materials so that they can fully contact the heat for drying, thereby improving the drying efficiency and preventing the residual materials from forming dirt on the inner wall surface of the dryer. Finally, it can also conveniently separate large and small materials and dry them separately to prevent excessive accumulation that affects the heating effect.
[0035] A specific operation flow of this embodiment is as follows: first, by utilizing the gravity of the base 3 and cooperating with the ball bearings 13 to reduce the friction resistance, the base 3 can be kept at the bottom of the drum dryer 1 and in a vertically upward state when the drum dryer 1 rotates. At this time, after being driven by the drum dryer 1 through the blocking sleeve 11, the rotational power is transmitted to the outer ring frame 4 through the transmission gear 12, so that the paddle 2 and the drum dryer 1 rotate in the opposite direction. At this time, the paddle 2 lifts the accumulated materials and automatically slides down at a certain height, and then hits the surface of the limit shaft 8 to be crushed by the crushing nails 9. Finally, the guide slope 14 can be used to guide the materials located at both ends of the drum dryer 1 to the inner area, so that they can receive the sufficient heating effect in time, thereby improving the quality of the drying operation.
