Description

Technical Field

[0001] This utility model relates to the field of biomass fuel technology, and in particular to a biomass fuel roasting device. Background Technology

[0002] Biomass fuel refers to fuel made by burning biomass materials, mainly agricultural and forestry waste (such as straw, sawdust, sugarcane bagasse, rice husks, etc.). It is a new type of clean fuel that can be directly burned by using agricultural and forestry waste as raw materials and processing them through crushing, mixing, extrusion, drying and other processes. In the production process of biomass fuel, 30%-50% of the water content in biomass fuel needs to be removed.

[0003] A search revealed a Chinese patent (application number "202322857674.0") that discloses "a biomass fuel drying device." This device includes a cabinet door, a cabinet body, a heating belt, and a support block. The support block is located inside the cabinet body, and a grate and a liquid collection box are mounted inside the cabinet body via slots in the support block. The heating belt and a fan are also installed inside the cabinet body. However, this drying device cannot dry the biomass fuel in real time during use, requiring frequent loading and unloading, resulting in low efficiency. Furthermore, the lack of agitation of the biomass fuel prevents it from fully contacting the heat, further contributing to low drying efficiency. Utility Model Content

[0004] This utility model provides a baking device for biomass fuel, which solves the problems proposed in the prior art: the separation device cannot dry biomass fuel in real time, requires frequent loading and unloading of biomass fuel, resulting in low working efficiency; at the same time, the biomass fuel is not turned over, so the biomass fuel cannot fully contact the heat, resulting in low drying efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A biomass fuel roasting device includes a fixed base with a heating mechanism on the fixed base. The heating mechanism includes an outer cylinder with several mounting ports on its outer wall, several PTC heaters installed in the mounting ports using high-temperature resistant sealant, and several spiral guide plates welded to the inner wall of the outer cylinder. Each outer cylinder is equipped with a conveying assembly, which includes a conveying cylinder with several feed ports on its lower outer wall, a ventilation shaft with a hot air pipe installed at its lower part via a rotary joint, and spiral blades welded to the outer wall of the ventilation shaft. A mounting plate is provided below the fixed base, and a drive motor is bolted to the bottom outer wall of the mounting plate.

[0006] Preferably, the fixing seat has a mounting hole on its outer wall at the center, and a support frame is bolted to the bottom outer wall of the fixing seat.

[0007] Preferably, the lower part of the outer cylinder is fixed in the mounting hole, and a plurality of mounting ports on the outer cylinder are each fitted with a filter screen, and the plurality of filter screens respectively abut against the outer wall of a plurality of PTC heaters, and the plurality of guide plates respectively abut against the outer wall of a plurality of filter screens.

[0008] The above scheme generates heat through multiple PTC heaters to heat multiple filters and multiple guide plates. The spiral guide plates guide the biomass fuel, allowing the biomass fuel to slide along the guide plates. The biomass fuel comes into contact with the filters and guide plates, and the heat on the filters and guide plates heats the biomass fuel.

[0009] Preferably, the conveying cylinder is welded to the inner wall at the center of the bottom of the outer cylinder, the upper part of the ventilation shaft passes through and is connected to the outer wall of the conveying cylinder through a bearing, and the lower part of the ventilation shaft passes through and is connected to the outer wall at the bottom of the outer cylinder through a bearing. An air outlet is opened on the upper outer wall of the ventilation shaft, and a discharge frame is fixed on the upper inner wall of the conveying cylinder.

[0010] The above scheme connects the ventilation shaft to the hot air duct, through which hot air is introduced to heat the ventilation shaft. The heat is then transferred to the spiral blades, which simultaneously transport and heat the biomass fuel.

[0011] Preferably, a feed hopper is welded to the top outer wall of the outer cylinder, and the feed hopper is concentric with the conveying cylinder.

[0012] Preferably, the mounting plate is welded to the upper inner wall of the support frame at both ends, the top of the output shaft of the transmission motor is connected to a rotating shaft through a coupling, and a drive pulley is connected to the outer wall of the rotating shaft through a spline. A driven pulley is connected to the lower outer wall of the conveying cylinder through a spline, and the driven pulley forms a transmission engagement with the drive pulley through a belt.

[0013] The above scheme uses a belt to drive the output shaft of the drive motor to rotate the ventilation shaft and the spiral blades, and the spiral blades transport biomass fuel.

[0014] The beneficial effects of this utility model are as follows: 1. Multiple PTC heaters generate heat and heat multiple filters and multiple guide plates. The spiral guide plates guide the biomass fuel, allowing the biomass fuel to slide along the guide plates. The biomass fuel comes into contact with the filters and guide plates, and the heat on the filters and guide plates heats the biomass fuel. 2. The output shaft of the drive motor is driven by a belt to rotate the ventilation shaft and the spiral blades. The ventilation shaft is connected to the hot air pipe, and hot air is introduced into the hot air pipe. The hot air heats the ventilation shaft, and then the heat is transferred to the spiral blades. The spiral blades transport the biomass fuel while heating the biomass fuel.

[0015] In summary, this invention can continuously dry biomass fuel without frequent handling, thus improving work efficiency. It can also tumble the biomass fuel while it is being transported, ensuring that the fuel is fully in contact with heat and improving drying efficiency. Attached Figure Description
