Description

Technical Field

[0001] This utility model is a biomass fuel powder iron removal device, belonging to the technical field of biomass fuel production equipment. Background Technology

[0002] Biomass fuel refers to fuel made by burning biomass materials. Biomass fuel generally includes agricultural and forestry waste (such as straw, sawdust, bagasse, rice husks, etc.), old furniture boards, and old templates. Among these, old furniture boards and old templates usually contain iron objects such as nails and rivets. However, since biomass fuel is produced by pressing biomass fuel powder, the biomass fuel powder usually contains iron impurities. These iron impurities can affect the combustion performance and calorific value of the fuel, and may even damage fuel processing and combustion equipment. Therefore, iron removal treatment is required for biomass fuel powder during the biomass fuel production process.

[0003] Patent No. CN220547086U mentions a biomass fuel powder iron removal device. This device uses magnetic materials to adsorb and remove iron impurities from biomass fuel powder. It can also clean and collect iron impurities on the surface of the magnetic materials without stopping the machine for maintenance, effectively improving the iron removal efficiency of biomass fuel powder. However, after collecting the iron impurities, this device still requires manual operation of an open collection box to move the iron impurities to the outside of the box, which requires further improvement in ease of use. There is an urgent need for a biomass fuel powder iron removal device to solve the above-mentioned problems. Utility Model Content

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0015] Please see Figures 1-7 This utility model provides a technical solution: a biomass fuel powder iron removal device, including a support plate 1, a first screening box 5, and a second screening box 20. Side plates 6 are symmetrically installed on the upper front end of the support plate 1, and a first electric push rod 7 is installed on the right end of the right side plate 6. The output shaft of the first electric push rod 7 passes through the right side plate 6 located above the support plate 1. A main housing 3 is installed in the middle of the upper part of the support plate 1. Through slots 16 are provided on the front and rear sides of the main housing 3, and first guide plates 17 are inclinedly installed in the two through slots 16 respectively. A second guide rod 18 is slidably installed on the right side of the main box 3, and a third electric push rod 21 is installed on the left side of the main box 3. A first electric sliding door 12 is installed on the front and rear sides of the first screening box 5, and a second electric sliding door 23 is installed on the front and rear sides of the second screening box 20. Electromagnetic plates 11 are installed on the bottom inner surfaces of the first screening box 5 and the second screening box 20. This design solves the problem that the original device still required manual operation of the open collection box to move the iron impurities to the outside of the box after collecting them, and the ease of use needs to be further improved.

[0016] As the first embodiment of this utility model: A first guide rod 10 is rotatably installed on the left end of the first screening box 5. The first guide rod 10 is slidably connected to the side plate 6 located on the left side above the support plate 1. A first motor 9 is installed at the output shaft end of the first electric push rod 7. The output shaft of the first motor 9 is fixedly connected to the right side of the first screening box 5. By slidably connecting the first guide rod 10 to the side plate 6 located on the left side above the support plate 1, the stability of the first screening box 5 during movement is improved. The first motor 9 facilitates the adjustment of the tilt angle of the first screening box 5. The output shaft of the third electric push rod 21 passes through the left side wall of the main box 3. A second motor 22 is installed at the output shaft end of the third electric push rod 21. The output shaft of the second motor 22 is fixedly connected to the left side of the second screening box 20. A round shaft 24 is rotatably connected to the right side of the second screening box 20. The round shaft 24 is fixedly connected to the second guide rod 18. The second motor 22 and the round shaft 24 facilitate the adjustment of the tilt angle of the second screening box 20.

[0017] A feed shell 8 is slidably installed at the center of the upper part of the main housing 3. Right-angle plates 13 are installed at the left and right ends of the upper part of the main housing 3. Second electric push rods 14 are installed below the horizontal ends of the two right-angle plates 13 respectively. The output shaft ends of the two second electric push rods 14 are connected to the left and right sides of the feed shell 8 through connecting plates 15 respectively. The two second electric push rods 14 facilitate the adjustment of the height of the feed shell 8. A second guide plate 19 is installed at an angle above the support plate 1. The second guide plate 19 is located below the main housing 3. A material box 4 is installed at the front end of the support plate 1. An iron impurity collection box 2 is installed at the rear end of the support plate 1. The second guide plate 19 facilitates the conveying of iron impurities inside the first screening box 5 to the iron impurity collection box 2. Both the first motor 9 and the second motor 22 are servo motors.

[0018] As a second embodiment of this utility model: Before use, the device is connected to an external power source. Then, the two second electric push rods 14 synchronously drive the feed shell 8 downward, so that the lower end of the feed shell 8 abuts against the upper part of the second screening box 20, forming a closed material conveying space and reducing the diffusion of material powder. Next, the material is added into the feed shell 8, and the material will fall into the second screening box 20. Then, the feed shell 8 is moved upward and reset, and the third electric push rod 21 and the electromagnetic plate 11 inside the second screening box 20 are activated, so that the third electric push rod 21 drives the second screening box 20. The material moves rapidly back and forth along the second guide rod 18, thus vibrating the material. The electromagnetic plate 11 inside the second screening box 20 attracts iron impurities in the material. Then, the second electric sliding door 23 near the first screening box 5 is opened, causing the second motor 22 to rotate the second screening box 20, tilting it at a certain angle. At this time, the material slides onto the corresponding first guide plate 17 and into the first screening box 5. Then, the second electric sliding door 23 near the first screening box 5 is closed. The sliding door 23 is opened, and the second electric sliding door 23 near the iron impurity collection box 2 is opened, causing the second motor 22 to drive the second screening box 20 to rotate in the opposite direction and tilt to a certain angle. Then, the electromagnetic plate 11 inside the second screening box 20 is de-energized. At this time, the iron impurities will slide onto the corresponding first guide inclined plate 17, and then onto the second guide inclined plate 19, and finally slide into the iron impurity collection box 2. The material inside the first screening box 5 can be moved quickly left and right by activating the first electric push rod 7. The electromagnetic plate 11 inside the first screening box 5 is activated to perform secondary adsorption on the residual iron impurities in the material. After adsorption is completed, the corresponding first electric sliding door 12 is opened, and the first motor 9 drives the first screening box 5 to tilt to a certain angle, allowing the material to slide into the material box 4. Finally, the other first electric sliding door 12 is opened, and the first screening box 5 is tilted to a certain angle. The electromagnetic plate 11 inside the first screening box 5 is de-energized, allowing the remaining iron impurities to slide onto the second guide plate 19 and finally into the iron impurity collection box 2.
