Description

Technical Field

[0001] This utility model belongs to the field of biomass pellet screening, specifically, it relates to a biomass pellet processing and screening device. Background Technology

[0002] Biomass pellets are granular products made from agricultural and forestry waste through processes such as crushing, mixing, drying, and extrusion. They are a new type of clean fuel. During the processing of biomass pellets, internal impurities need to be screened.

[0003] Chinese Patent Application No. CN202323296412.8 discloses a biomass fuel pellet processing and screening device. Addressing the problem that existing biomass fuel pellet processing and screening devices have inconvenient screen frame disassembly, leading to difficulties in cleaning or replacing screen frames with different specifications to suit different screening needs, the following solution is proposed: It includes an outer shell, a first-stage screen frame, and a second-stage screen frame. The first-stage screen frame is slidably mounted on the top of the outer shell, and the second-stage screen frame is slidably mounted between the inner walls of the front and rear sides of the outer shell. This utility model has a reasonable structural design. The first-stage screen frame is positioned by the cooperation of an extension plate, a vertical plate, and a movable sleeve, while the second-stage screen frame is positioned by the cooperation of a positioning rod, a positioning groove, and a support spring. The first-stage screen frame, the second-stage screen frame, and the outer shell can be quickly connected, and the first-stage and second-stage screen frames are easy to disassemble, resulting in high reliability.

[0004] However, the existing technology mentioned above cannot seal the screening process, which causes dust to fly around during the screening process. At the same time, it cannot disperse the biomass pellets, which tend to accumulate in a certain place on the screening plate, affecting the screening effect. Furthermore, the screening plate is prone to clogging, resulting in poor screening efficiency.

[0005] In view of this, this utility model is hereby proposed. Utility Model Content

Detailed Implementation

[0027] The present invention will now be described in further detail with reference to the accompanying drawings.

[0028] Please see Figure 1-4As shown, this embodiment provides a biomass pellet processing screening device, including a screening box 1 and a protective door 2. The protective door 2 is rotatably installed on the front side of the screening box 1, improving the sealing effect of the screening box 1. An anti-clogging feeding component 3 is installed through the top of the screening box 1. A fixing frame 4 is fixed on one side of the screening box 1, which can fix a movable material distribution component 5, improving the stability of the movable material distribution component 5 during operation. The movable material distribution component 5 is fixedly installed on one side inside the fixing frame 4, and the other end of the movable material distribution component 5 is rotatably installed on the other side inside the screening box 1. A material distribution rack 6 is fixed on one side of the movable material distribution component 5. A sliding groove is opened inside the screening box 1, and a screening plate 7 can move up and down inside the sliding groove. The screening plate 7 is arranged inside the sliding groove and is located between the movable material distribution components 5. A baffle 8 is fixed on the top of the screening plate 7. A collection frame 9 is provided on the inner wall of the bottom of the screening box 1, which can collect the screened impurities.

[0029] One application of this embodiment is as follows: the biomass pellets to be screened are manually poured into the anti-clogging feeding assembly 3, which ensures that the biomass pellets are fed evenly and prevents clogging. The biomass pellets can fall onto the screening plate 7 through the distribution rack 6. At the same time, the movable distribution assembly 5 can move the screening plate 7 left and right to prevent the biomass pellets from accumulating in one place on the screening plate 7, which would affect the screening effect. The movable distribution assembly 5 can also move the screening plate 7 upward, and the screening plate 7 can move downward under its own gravity, which effectively prevents the screening plate 7 from clogging and ensures a good screening effect. When feeding the screened biomass pellets, the protective door 2 can be rotated to remove the screening plate 7. The baffle 8 can prevent the screened biomass pellets from falling into the screening box 1.

[0030] The anti-clogging feeding assembly 3 includes a first feeding frame 301 and a second feeding frame 302. The bottom of the first feeding frame 301 is fixedly installed on the top of the screening box 1. One end of the second feeding frame 302 is fixed to one side of the first feeding frame 301. The top of the second feeding frame 302 has a feeding port for easy addition of biomass pellets. A rotating motor 303 is fixedly installed on the top of the first feeding frame 301. A rotating shaft 304 is installed at the output end of the rotating motor 303. The bottom of the rotating shaft 304 is rotatably installed on the inner wall of the bottom of the first feeding frame 301. A conveying blade 305 is fixed on the outside of the rotating shaft 304. A gooseneck tube 306 is fixed on the bottom of the first feeding frame 301. The gooseneck tube 306 is a metal shaped flexible tube that can be bent arbitrarily and has a defined direction. The other end of the gooseneck tube 306 is fixedly installed on the top of the distribution frame 6.

[0031] In this embodiment, the rotating motor 303 drives the rotating shaft 304 to rotate, and the conveying blades 305 can rotate with the rotating shaft 304. Then, the biomass pellets that need to be screened are manually poured into the second feeding rack 302. Under the action of their own gravity, the biomass pellets can slide into the first feeding rack 301 and be conveyed by the conveying blades 305, avoiding pouring too much or too little at one time, thus improving the uniformity of feeding. Finally, they flow into the distribution rack 6 through the gooseneck tube 306.

[0032] The movable material distribution assembly 5 includes a servo motor 501 and a screw 502. The servo motor 501 is fixedly installed inside one side of the fixed frame 4. One end of the screw 502 is installed at the output end of the servo motor 501, and the other end of the screw 502 is rotatably installed inside the screening box 1 on the other side. A synchronous wheel 503 is fixed to the outside of the screw 502, and a slider 505 is slidably installed on the outside of the screw 502. The slider 505 is threadedly connected to the screw 502 and is located inside the screening box 1. An installation shaft 506 is rotatably installed on the other side inside the screening box 1. The installation shaft 506 is located below the screw 502. A lifting block 507 is fixed to the outside of the installation shaft 506, and a synchronous wheel 503 is fixedly installed on the outside of the installation shaft 506. A synchronous belt 504 is meshed on the outside of the two synchronous wheels 503. Both the two synchronous wheels 503 and the synchronous belt 504 are located on the outside of the screening box 1.

[0033] In this embodiment, the servo motor 501 drives the screw 502 to rotate. Slide rods are fixed on both sides inside the screening box 1. A slider 505 is slidably mounted on the outside of the slide rods. The slide rods limit the slider 505, allowing it to slide on the screw 502 instead of rotating. This enables the material distribution frame 6 to move, facilitating uniform feeding of biomass pellets. Teeth are provided on the outer sides of the two synchronous pulleys 503 and the inner side of the synchronous belt 504. The two synchronous pulleys 503 and the synchronous belt 504 can rotate simultaneously, driving the mounting shaft 506 and the lifting block 507 to rotate. The lifting block 507 can lift the screening plate 7 upwards. The screening plate 7 moves up and down under its own gravity, repeatedly lifting and falling, preventing clogging of the screening plate 7 and improving the screening effect of biomass pellets.
