AI Technical Summary
Existing biomass drying and screening devices fail to quantitatively feed biomass into the working chamber when processing large quantities of biomass materials, resulting in insufficient drying. Consequently, the subsequent screening plates adhere to the damp biomass, reducing work efficiency.
The quantitative component includes a cylinder and a spiral blade. The spiral blade is driven by a power component to quantitatively introduce biomass into the working chamber. Combined with a heating chamber to provide heat for drying, the biomass is then sieved through a sieve plate.
This technology enables quantitative input and thorough drying of biomass, improves drying and screening efficiency, reduces adhesion, and enhances the overall operating efficiency of the device.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical engineering technology, specifically to a biomass drying and screening device. Background Technology
[0002] With the rapid development of the global economy, the reserves of traditional fossil fuels such as coal, oil, and natural gas are gradually decreasing, putting enormous pressure on energy supply. Biomass energy, as a renewable energy source, has huge development potential and can alleviate the energy shortage problem to some extent.
[0003] When existing biomass drying and screening devices process large quantities of biomass, the biomass does not enter in a measured manner as it travels from the feed inlet to the working chamber. When a large amount of biomass floods into the working chamber, it leads to insufficient drying of the biomass, which in turn causes the screening plate to stick to the damp biomass, reducing the overall efficiency of the biomass drying and screening device. To address the shortcomings of the existing technology, this utility model provides a biomass drying and screening device to solve the above problems. Utility Model Content
[0004] In view of the shortcomings of the existing technology, this utility model provides a biomass drying and screening device, which solves the problem of insufficient biomass drying.

[0006] The quantitative component includes a cylinder and a spiral blade. The cylinder is fixedly connected between the buffer tank and the feed inlet. The spiral blade is rotatably connected inside the cylinder. A second rotating shaft is fixedly connected to the center of the spiral blade. A feed groove is provided on the cylinder.
[0007] A power assembly that provides power to the second rotating shaft is fixedly connected to the working box;
[0008] Preferably, the power assembly includes a motor and a first rotating shaft. The motor is fixedly connected to the work box, the first rotating shaft is fixedly connected to the output end of the motor, a first pulley is fixedly connected to the first rotating shaft, a second pulley is provided on the second rotating shaft, and a belt is provided between the first pulley and the second pulley.

[0013] This utility model discloses a biomass drying and screening device, which has the following beneficial effects:
[0014] This biomass drying and screening device uses a quantitative component to quantitatively feed a large amount of biomass into the working chamber. During this process, the motor in the power component provides power to rotate the second shaft, which drives the spiral blades forward. As the spiral blades move forward, they carry the biomass into the working chamber, ensuring that a large amount of biomass is quantitatively fed into the working chamber, thus reducing the burden on subsequent drying and screening operations.

[0023] This application provides a biomass drying and screening device that solves the problem of insufficient biomass drying, enabling large quantities of biomass to enter the working chamber in batches and in quantitative quantities, thus reducing the burden on subsequent drying and screening work.
[0024] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.
[0025] This utility model discloses a biomass drying and screening device, according to the attached... Figure 1-5 As shown,
[0026] The biomass drying and screening device includes a working box 1, which contains a drying working area and a screening working area. A heating box 13 is fixedly connected to the working box 1, which provides heat to the drying working area to accelerate drying. A sieve plate 5 is provided inside the working box 1 to screen the dried biomass. A buffer box 14 is fixedly connected to the upper surface of the working box 1. The buffer box 14 buffers the biomass brought in by the quantitative component 7 and then drops it into the working box 1. The working box 1 is provided with a feed inlet 4. A large amount of biomass material to be processed is poured into the feed inlet 4 and introduced into the buffer box 14 through the quantitative component 7. The quantitative component 7 is provided between the buffer box 14 and the feed inlet 4.
[0027] The quantitative component 7 includes a cylinder 71 and a spiral blade 73. The spiral blade 73 is driven by a second rotating shaft 74 to propel the spiral blade 73 forward, allowing a certain amount of biomass material to enter the buffer tank 14. The cylinder 71 is fixedly connected between the buffer tank 14 and the feed inlet 4. The cylinder 71 serves to stabilize the biomass during the process from the feed inlet 4 to the buffer tank 14, preventing it from falling out. The spiral blade 73 is rotatably connected inside the cylinder 71, and the center of the spiral blade 73 is fixedly connected to the second rotating shaft 74. A feed trough 72 is provided on the cylinder 71, and a large amount of biomass enters the feed trough 72 from the feed inlet 4.
[0028] A power assembly 6 is fixedly connected to the working box 1 to provide power to the second rotating shaft 74. The motor 61 in the power assembly 6 provides power to the second rotating shaft 74, so that the metering component 7 starts to work.
[0029] The power assembly 6 includes a motor 61 and a first rotating shaft 62. The motor 61 is fixedly connected to the working box 1, and the first rotating shaft 62 is fixedly connected to the output end of the motor 61. A first pulley 64 is fixedly connected to the first rotating shaft 62, and a second pulley 65 is provided on the second rotating shaft 74. A belt 63 is provided between the first pulley 64 and the second pulley 65.
[0030] The working box 1 is equipped with a slag outlet 11. When the drying and screening work is completed, the screened biomass slag can be taken out through the slag outlet 11.
[0031] A baffle 3 is engaged inside the discharge port 12. During the drying and screening process, the baffle 3 engages with the discharge port 12 to prevent heat loss and to prevent biomass spillage. When the drying and screening is completed, the baffle 3 is pulled out from the discharge port 12, and the dried and screened biomass material can be taken out.
[0032] A base 2 is fixedly connected to the lower surface of the work box 1.
[0033] When a large amount of biomass needs to be dried and screened, the motor 61 is started, and then the biomass is poured into the feed inlet 4. The biomass is introduced into the feed trough 72 from the feed inlet 4, realizing the initial quantitative step. Then, the motor 61 drives the first rotating shaft 62 to rotate. The first pulley 64 on the first rotating shaft 62 drives the belt 63, which in turn drives the second pulley 65 to rotate. The second pulley 65 drives the second rotating shaft 74 to rotate. The spiral blades 73 on the second rotating shaft 74 push forward, pushing the biomass into the buffer box 14. The biomass falls from the buffer box 14 into the working box 1, and the drying and screening work begins. After the drying and screening work is completed and the temperature drops, the biomass residue is taken out from the residue outlet 11. The biomass material can be taken out from the discharge outlet 12 by opening the baffle 3. A large amount of biomass is put into the working box 1 for batch quantitative feeding, which can improve the subsequent drying and screening effect.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
