Description

Technical Field

[0001] This utility model relates to the field of biomass drying room technology, specifically a biomass drying room. Background Technology

[0002] A biomass drying room is a device that uses biomass energy for drying. It is widely used in industries such as agriculture and food processing. The biomass drying room generates heat by burning fuels such as biomass briquettes to dry materials.

[0003] When a biomass drying chamber is in use, the heat generated by the combustion of biomass fuel in the combustion chamber is transferred to the material through a heat exchanger. The material is dried by the flow of hot air in the drying chamber, causing the moisture in the material to evaporate. However, existing biomass drying chambers do not facilitate the pretreatment of the biomass fuel during combustion, which makes it difficult to burn large and moist biomass fuel for a long time, reducing the combustion efficiency of the biomass fuel and thus reducing the drying efficiency of the biomass drying chamber.

[0004] Therefore, it is necessary to provide a new biomass drying room to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a biomass drying room that facilitates the pretreatment of burning biomass fuel.

[0008] In order to prevent biomass fuel from accumulating inside the crushing chamber, the biomass drying chamber provided by this utility model preferably has two inclined plates fixed inside the crushing chamber. The two inclined plates are symmetrically distributed inside the crushing chamber, and the surface of the inclined plates is smooth.

[0009] To achieve the effect of fixing the crushing box to the top of the burner, as a biomass drying chamber provided by this utility model, preferably, two vertical blocks are fixed on the outside of the burner in a left-right symmetrical arrangement, and two assembly blocks are fixed on the bottom of the crushing box in a left-right symmetrical arrangement. The assembly blocks are inserted into the assembly slots opened in the vertical blocks. A fixing bolt is provided on one side of the vertical block. One end of the fixing bolt is inserted into the through hole opened in the vertical block, and the other end of the fixing bolt extending out of the through hole is screwed into the threaded groove opened in the vertical block.

[0010] In order to achieve a more stable rotation of the rotating shaft inside the crushing chamber, the biomass drying chamber provided by this utility model preferably has a horizontal plate sleeved inside the crushing chamber and outside the rotating shaft. Both ends of the horizontal plate are fixedly connected to the inner wall of the crushing chamber. A bearing seat is fixed at the bottom of the horizontal plate and at the end of the rotating shaft.

This, in turn, improves the drying efficiency of the main body of the drying chamber. It solves the problem that existing biomass drying chambers are not convenient for pre-treating biomass fuel during combustion, which makes it take longer to burn larger and moist biomass fuel, thus reducing the combustion efficiency of biomass fuel and consequently reducing the drying efficiency of the biomass drying chamber.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 ,in Figure 1 This is a schematic diagram of the structure of the biomass drying room provided by this utility model; Figure 2 This is a top view of the structure of this utility model; Figure 3 This is a schematic diagram showing the connection between the burner and the pulverizing box of this utility model; Figure 4 This is a front view of the main structure of the drying room of this utility model; Figure 5 This is a top view of the combustion chamber structure of this utility model; Figure 6 This is a schematic diagram of the connection between the horizontal plate and the baffle of this utility model. A biomass drying chamber includes a main body 1, several trolleys 2 are arranged inside the main body 1, a burner 3 is arranged outside the main body 1, a spiral conveying pipe 4 is arranged at the bottom of the burner 3, a circulating fan 5 and a hot air furnace 6 are respectively arranged inside the main body 1, the other end of the spiral conveying pipe 4 extends into the hot air furnace 6, the top of the hot air furnace 6 is connected to a flue pipe 7, the top end of the flue pipe 7 extends to the outside of the main body 1; a crushing box 301 is arranged on the top of the burner 3, a feeding frame 302 is arranged on the top of the crushing box 301, a support plate 303 is fixed on the top of the feeding frame 302, a motor 304 is fixed on the top of the support plate 303, a rotating shaft 305 is fixedly connected to the output end of the motor 304, several crushing blades 306 are fixed to the outside of the crushing box 301, a discharge port 307 is opened at the bottom of the crushing box 301, and a heating resistance wire 308 is arranged inside the crushing box 301.

[0023] With the above technical solution, both the motor 304 and the heating resistance wire 308 are externally powered. The material to be dried is placed on the trolley 2, and then several trolleys 2 are pushed into the drying chamber 1. Biomass fuel is poured into the feed frame 302, causing it to fall into the crushing box 301. The motor 304 drives the rotating shaft 305 and the crushing blades 306 to rotate. The crushing blades 306 can crush the larger biomass fuel. At the same time, when the biomass fuel is crushed, the heat generated by the heating resistance wire 308 can dry the damp biomass fuel. After the crushed and dried biomass fuel is burned by the burner 3, the heat generated by the combustion enters the drying chamber 1 through the hot air furnace 6, thereby drying the material on the trolley 2. The circulating fan 5 can effectively improve the drying efficiency of the material. Through the crushing and drying of the biomass fuel, the biomass fuel is burned more completely, effectively shortening the combustion time and increasing the combustion efficiency, thereby improving the drying efficiency of the drying chamber 1.

[0024] Reference Figure 3 Inside the crushing box 301, there are two inclined plates 309. The two inclined plates 309 are symmetrically distributed inside the crushing box 301. The surface of the inclined plates 309 is smooth. The crushed biomass fuel slides down through the inclined plates 309 into the burner 3 to prevent the biomass fuel from accumulating at the bottom of the crushing box 301.

[0025] Reference Figure 3 Two vertical blocks 310 are fixed on the outside of the burner 3, arranged symmetrically from left to right. Two assembly blocks 311 are fixed on the bottom of the pulverizing box 301, arranged symmetrically from left to right. The assembly blocks 311 are inserted into the assembly slots 312 opened in the vertical blocks 310. A fixing bolt 313 is provided on one side of the vertical blocks 310. One end of the fixing bolt 313 is inserted into the through hole 314 opened in the vertical blocks 310. The other end of the fixing bolt 313 extends out of the through hole 314 and is screwed into the threaded groove 315 opened in the vertical blocks 310. The assembly block 311 at the bottom of the pulverizing box 301 is inserted into the assembly slot 312 opened in the vertical blocks 310. Then, one end of the fixing bolt 313 passes through the through hole 314 and is screwed into the threaded groove 315. The assembly block 311 can be fixed in the assembly slot 312 by the cooperation of the fixing bolt 313 and the threaded groove 315, thereby fixing the pulverizing box 301 to the top of the burner 3.

[0026] Reference Figure 3A horizontal plate 316 is fitted inside the crushing box 301 and outside the rotating shaft 305. Both ends of the horizontal plate 316 are fixedly connected to the inner wall of the crushing box 301. A bearing seat 317 is fixed at the bottom of the horizontal plate 316 and at the end of the rotating shaft 305. The rotating shaft 305 is rotatably connected inside the bearing seat 317. When the rotating shaft 305 rotates, its bottom end rotates inside the bearing seat 317. The bearing seat 317 makes the rotating shaft 305 more stable during rotation.

[0027] Reference Figure 3 and Figure 6 The crushing chamber 301 is equipped with two baffles 318. A plug 319 is fixedly connected to one side of the baffle 318. The plug is inserted into the slot 320 opened in the horizontal plate 316. One end of the baffle 318 is inserted into the insertion hole 321 opened in the crushing chamber 301. A pull block 322 is fixedly connected to the outside of the insertion hole 321 of the baffle 318. When the crushing chamber 301 crushes biomass fuel, the plug 319 at one end of the baffle 318 is inserted into the slot 320 through the insertion hole 321. The baffle 318 can block the biomass fuel, so that the biomass fuel is crushed in the crushing chamber 301 for a longer time, thereby making the biomass fuel crushed more thoroughly.

[0028] The implementation principle of a biomass drying chamber according to an embodiment of this utility model is as follows: the material to be dried is placed on a trolley 2, and then several trolleys 2 are pushed into the main body 1 of the drying chamber. Biomass fuel is poured into the feeding frame 302, causing the biomass fuel to fall into the crushing box 301. The motor 304 drives the rotating shaft 305 and the crushing blades 306 to rotate. The crushing blades 306 can crush the large-volume biomass fuel. At the same time, when the biomass fuel is crushed, the heat generated by the heating resistance wire 308 can dry the wet biomass fuel. After the crushed and dried biomass fuel is burned by the burner 3, the heat generated by the combustion enters the main body 1 of the drying chamber through the hot air furnace 6, thereby drying the material on the trolley 2. The circulating fan 5 can effectively improve the drying efficiency of the material. Through the crushing and drying of the biomass fuel, the biomass fuel is burned more completely, effectively shortening the burning time of the biomass fuel and making the biomass fuel combustion efficiency higher, thereby improving the drying efficiency of the main body 1 of the drying chamber.
