Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-6 The present invention provides the following technical solution:

[0027] A screening device for biomass pellet processing includes a support frame 1, a screen 2 slidably disposed inside the support frame 1, a self-cleaning component 3 disposed at the bottom of the screen 2, and an angle adjustment component 4 disposed on the surface of the support frame 1.

[0028] The angle adjustment assembly 4 includes four pins 41, which are bolted to the front and rear sides of the support frame 1. A rotating ring 42 is sleeved on the surface of the pin 41, and a mounting seat 43 is bolted to the bottom of the rotating ring 42. Telescopic electric cylinders 44 are bolted to the bottom of the two front mounting seats 43, and first support feet 45 are bolted to the bottom of the telescopic electric cylinders 44. Second support feet 46 are bolted to the bottom of the two rear mounting seats 43.

[0029] In this embodiment: On the biomass pellet processing production line, in order to achieve effective screening of biomass pellets, the main frame of this equipment is a support frame 1. The support frame 1 is made of high-strength metal material to ensure its structural stability and durability. Inside the support frame 1, a sliding screen 2 is installed. The screen 2 performs precise screening according to the size of the biomass pellets. To ensure the normal operation and efficient screening of the screen 2, a self-cleaning component 3 is set at the bottom of the screen 2. At the same time, an angle adjustment component 4 is set on the surface of the support frame 1. The angle adjustment component 4 includes four pins 41. Shaft 41 is bolted to the front and rear sides of the support frame 1 respectively. A rotating ring 42 is fitted on the surface of the shaft 41. The rotating ring 42 can rotate flexibly on the shaft 41. A mounting seat 43 is bolted to the bottom of the rotating ring 42. Telescopic electric cylinders 44 are bolted to the bottom of the two mounting seats 43 on the front side. The telescopic electric cylinders 44 are selected as reliable and stable products. The bottom of the cylinders 44 is bolted with a first support foot 45. The bottom of the two mounting seats 43 on the rear side is bolted with a second support foot 46. By telescopically extending and retracting the electric cylinders 44, the tilt angle of the support frame 1 can be changed, thereby adjusting the screening effect of the screen 2.

[0030] Specifically, such as Figure 3 As shown, the self-cleaning component 3 includes several connecting blocks 31, which are bolted to both sides of the bottom of the support frame 1.

[0031] Specifically, such as Figure 3 As shown, a crossbar 32 is bolted between the bottoms of two adjacent connecting blocks 31 on the left and right.

[0032] Specifically, such as Figure 3 As shown, a bristle brush 33 is bolted to the top of the crossbar 32, and the top of the bristle brush 33 contacts the bottom of the screen 2.

[0033] In this embodiment: In this screening equipment, the self-cleaning component 3 plays an important role in ensuring the normal operation of the screen 2. The self-cleaning component 3 includes several connecting blocks 31, which are made of sturdy aluminum alloy and are bolted to both sides of the bottom of the support frame 1. The design of the connecting blocks 31 allows them to be firmly fixed to the support frame 1, providing stable support for subsequent components. A crossbar 32 is bolted between the bottoms of two adjacent connecting blocks 31. The crossbar 32 is made of solid stainless steel and has high strength and rigidity. The installation of the crossbar 32 ensures the structural stability of the entire self-cleaning component 3. A bristle brush 33 is bolted to the top of the crossbar 32. The bristle brush 33 is composed of high-quality bristles and a sturdy base plate. The top of the bristle brush 33 is in close contact with the bottom of the screen 2. When the screen 2 slides in the support frame 1 for screening, the bristle brush 33 will clean the bottom of the screen 2 to prevent biomass particles from clogging the screen holes, thereby ensuring the screening efficiency and effect of the screen 2.

[0034] Specifically, such as Figure 1 As shown, wear-resistant and anti-slip pads 5 are bolted to the bottom of the first support leg 45 and the second support leg 46, and an angle sensor 6 is provided on the right side of the support frame 1.

[0035] Specifically, such as Figure 6 As shown, a collection box 7 is bolted to the bottom of the screen 2. Rectangular holes 8 are opened on both sides inside the collection box 7, and the crossbar 32 passes through the rectangular holes 8 and is located inside the collection box 7.

[0036] In this embodiment: the bottom of the first support foot 45 and the second support foot 46 are both bolted with wear-resistant and anti-slip pads 5. The wear-resistant and anti-slip pads 5 are made of rubber material and have good wear resistance and anti-slip performance. They can increase the friction between the support foot and the ground, prevent the equipment from sliding and shaking during operation, and ensure the stable operation of the equipment. An angle sensor 6 is set on the right side of the support frame 1. It can determine the tilt angle of the screen 2 according to the tilt angle of the support frame, so as to adjust the extension and retraction of the telescopic cylinder 44 in time, realize the precise control of the tilt angle of the support frame 1, and realize the screening work with different needs. A collection box 7 is bolted to the bottom of the screen 2. Rectangular holes 8 are opened on both sides inside the collection box 7. The crossbar 32 passes through the rectangular holes 8 and is located inside the collection box 7. When the brush 33 cleans the bottom of the screen 2, the biomass particles that are cleaned off will fall into the collection box 7 for convenient centralized processing.

[0037] Specifically, such as Figure 5 As shown, a mounting block 9 is bolted to the front inner wall of the support frame 1. A screening motor 10 is bolted to the left side of the mounting block 9. The output shaft of the screening motor 10 extends to the right side of the mounting block 9 and is bolted to a turntable 11. A round rod 12 is bolted to the right side of the turntable 11. A connecting seat 13 is bolted to the front side of the screen 2. A transmission rod 14 is rotatably connected between the round rod 12 and the connecting seat 13.

[0038] Specifically, such as Figure 4 As shown, a feeding hopper 15 is bolted to the front side of the top of the support frame 1. A feeding hole 16 is opened on the rear side inside the feeding hopper 15. An adjusting baffle 17 is slidably arranged on the rear side inside the feeding hopper 15. The adjusting baffle 17 is used in conjunction with the feeding hole 16.

[0039] In this embodiment: To provide power for the sliding screening of the screen 2, a mounting block 9 is bolted to the inner front wall of the support frame 1. A screening motor 10 is bolted to the left side of the mounting block 9. The output shaft of the screening motor 10 extends to the right side of the mounting block 9 and is bolted to a turntable 11. A round rod 12 is bolted to the right side of the turntable 11. A connecting seat 13 is bolted to the front of the screen 2. A transmission rod 14 is rotatably connected between the round rod 12 and the connecting seat 13. When the screening motor 10 starts, the output shaft drives the turntable 11 to rotate, and the round rod 12 on the turntable 11 performs circular motion accordingly. The circular motion is converted into the sliding screening motion of the screen 2 within the support frame 1 by the transmission rod 14. A discharge hopper 15 is bolted to the front of the top of the support frame 1 to store the biomass pellets to be screened. A discharge hole 16 is opened on the rear side inside the discharge hopper 15. An adjusting baffle 17 is slidably installed on the rear side inside the discharge hopper 15. The adjusting baffle 17 works in conjunction with the discharge hole 16. The operator can change the opening size of the discharge hole 16 by sliding the adjusting baffle 17, thereby controlling the flow rate of biomass pellets into the screen 2 to adapt to different screening needs.

[0040] Working Principle: When this biomass pellet screening equipment is running, the operator first puts the biomass pellets to be screened into the hopper 15 on the front side of the top of the support frame 1. The hopper 15 has a discharge hole 16 on the rear side, and an adjusting baffle 17 is slidably installed on the rear side. The operator can change the opening size of the discharge hole 16 by sliding the adjusting baffle 17, thereby controlling the flow rate of biomass pellets into the screen 2 inside the support frame 1 to adapt to different screening requirements. The screening motor 10 on the mounting block 9 on the front inner wall inside the support frame 1 is started, and its output shaft drives the connected motor. As the turntable 11 rotates, the round rod 12 on the right side of the turntable 11 also performs a circular motion. Since the round rod 12 and the front connecting seat 13 of the screen 2 are rotatably connected through the transmission rod 14, the circular motion is converted into the sliding screening motion of the screen 2 within the support frame 1, thereby achieving precise screening of biomass particles according to size. During the screening process, the angle sensor 6 monitors the tilt angle of the support frame 1 in real time. Because four pins 41 are respectively bolted to the front and rear sides of both sides of the support frame 1, and rotating rings 42 are fitted on the pins 41, the bottom of the rotating rings 42 is installed... The base 43 is connected to the telescopic electric cylinder 44 and the second support foot 46. The bottom of the telescopic electric cylinder 44 is bolted to the first support foot 45. The angle sensor 6 feeds back the signal to the control system based on the monitored angle, thereby adjusting the telescopic amount of the telescopic electric cylinder 44 and changing the tilt angle of the support frame 1 to optimize the screening effect of the screen 2. At the same time, as the screen 2 slides, the self-cleaning component 3 installed at the bottom of the support frame 1 begins to function. The self-cleaning component 3 is fixed to both sides of the bottom of the support frame 1 by bolts. The solid bottom of the left and right adjacent connecting blocks 31 is not... A brush 33 is attached to the stainless steel crossbar 32. The top of the brush 33 is in close contact with the bottom of the screen 2, which cleans the bottom of the screen 2 and prevents biomass particles from clogging the screen holes. The cleaned particles fall into the collection box 7 attached to the bottom of the screen 2. The rectangular holes 8 on both sides of the inside of the collection box 7 allow the crossbar 32 to pass through for centralized processing. In addition, the wear-resistant and anti-slip pads 5 at the bottom of the first support foot 45 and the second support foot 46 are made of rubber material, which increases the friction with the ground and ensures the stability of the equipment during operation, preventing the equipment from sliding and shaking.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
