Description

Technical Field

[0001] The invention relates to the technical field of biomass fuel processing, and in particular to a biomass fuel production impurity removal device. Background Art

[0002] Biomass fuel, as a renewable energy source, has received extensive attention and research in recent years. Biomass fuel is mainly converted from biomass resources such as agricultural and forestry wastes and energy crops. Compared with traditional fossil fuels, biomass fuel has the advantages of strong renewability, low carbon emissions, and environmental friendliness. In addition, the use of biomass fuel helps reduce dependence on fossil fuels, and helps optimize the energy structure and protect the environment.

[0003] In the production process of biomass fuel, the pretreatment of raw materials is a key step, which directly affects the efficiency of subsequent processing and the quality of fuel. Pretreatment mainly includes drying, impurity removal and crushing of raw materials. Among them, impurity removal is a very critical step, mainly to remove non-biomass particles in the raw materials, such as sand and gravel and other impurities. The necessity of impurity removal is that if these impurities are not removed, they will cause equipment wear in the subsequent crushing process, reduce the service life of the equipment, and increase maintenance costs. More importantly, these hard impurities will not only not be burned during the combustion process, but also reduce the calorific value of the overall fuel and affect the combustion effect of the fuel.

DETAILED DESCRIPTION

[0042] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0043] In the present invention, unless otherwise stated, directional words such as "upper, lower, inside, outside" contained in a term merely represent the orientation of the term in normal usage, or are common names understood by those skilled in the art, and should not be regarded as limitations on the term.

[0044] Reference Figure 1-Figure 13 As shown, a biomass fuel production impurity removal equipment, the impurity removal equipment includes: a support frame 100, a screen drum 102 tiltably and rotatably arranged on a fixed disk 101 for preliminary impurity removal of the biomass fuel, and a filter plate 103 slidably arranged on the support frame 100 and located below the screen drum 102 and arranged parallel to the screen drum 102 for further impurity removal of the biomass fuel; wherein, the fixed disk 101 is fixedly arranged on the support frame 100, the support frame 100 is fixedly provided with a feeding mechanism 200 for directional feeding into the screen drum 102, the support frame 100 is provided with a sliding mechanism 500 for allowing the filter plate 103 to slide back and forth on the support frame 100 along the tilt direction of the filter plate 103, and the support frame 100 is provided with a cleaning mechanism 400 for cleaning the surface of the filter plate 103 to prevent clogging during impurity removal.

[0045] When in use, the feeding mechanism 200 is started to quantitatively and evenly feed the biomass fuel into the screen drum 102 to ensure that the screen drum 102 can efficiently perform preliminary impurity removal. The screen drum 102 starts to rotate under the drive of the motor, and the screen or sieve hole inside it performs preliminary screening on the fuel to separate larger impurities. At the same time, the inclined design of the screen drum 102 helps the fuel to continuously move downward during the rotation process, thereby improving the impurity removal efficiency. The fuel that has undergone preliminary impurity removal falls onto the filter plate 103 below through the outlet of the screen drum 102. The fine mesh or filter medium on the filter plate 103 can further remove fine impurities in the fuel. At this time, the sliding mechanism 500 is started to drive the filter plate 103 to slide back and forth along its inclined direction, so that the fuel is evenly distributed on the filter plate 103 and the impurity removal effect is enhanced. During the impurity removal process, the cleaning mechanism 400 works synchronously to clean the surface of the filter plate 103 to prevent impurities from clogging. Through the dual impurity removal design of the screen drum 102 and the filter plate 103, impurities in the biomass fuel can be removed more thoroughly, thereby improving the purity and use effect of the fuel. The sliding mechanism 500 enables the filter plate 103 to slide back and forth, which not only increases the uniformity of fuel distribution, but also enhances the impurity removal effect, ensuring that the fuel can be fully impurity-removed at all positions.

[0046] Reference Fig.10 As shown, the sliding mechanism 500 includes: a sliding roller 506 and a first driving member; the sliding roller 506 is fixedly arranged on two side surfaces of the filter plate 103 that are away from each other, and a sliding groove 505 for the sliding roller 506 to slide is opened on the support frame 100, and the first driving member is arranged on the inner side wall of the support frame 100 to drive the filter plate 103 to slide back and forth on the support frame 100 along the inclination direction of the filter plate 103.

[0047] When the biomass fuel begins to enter the impurity removal process and needs the filter plate 103 to further remove impurities, the first driving member is started, and the first driving member transmits power to the sliding roller 506 through its transmission mechanism, thereby driving the filter plate 103 to slide back and forth along the inclined direction in the slide groove 505 of the support frame 100. During the sliding process, the biomass fuel on the filter plate 103 is evenly spread and fully contacts with the filter medium to achieve a better impurity removal effect. As the first driving member continues to work, the filter plate 103 continues to slide back and forth in the slide groove 505 until the biomass fuel completes the impurity removal process and is collected.

[0048] Reference Figure 9-10As shown, the first driving member includes: a first turntable 502, a first guide rod 503, a first limit rod 504, a driving gear disc 507 and a first rack 508; wherein, the driving gear disc 507 is rotatably arranged on the inner wall of the support frame 100 through a rotating shaft 509 and meshes with the first rack 508, the first rack 508 is fixedly arranged on the side wall of the filter plate 103, the top of the driving gear disc 507 is fixedly provided with a first limit rod 504, the first limit rod 504 is slidably penetrated by a first guide rod 503, the first guide rod 503 is fixedly arranged at the surface edge of the first turntable 502, the driving motor 501 is fixedly arranged on the side wall of the support frame 100, its output shaft is horizontally arranged and the top end is fixedly connected to the first turntable 502.

[0049] When in use, first, start the driving motor 501 installed on the side wall of the support frame 100. The output shaft of the driving motor 501 is horizontally arranged and fixedly connected to the first rotating disk 502. Therefore, when the motor is started, it will drive the first rotating disk 502 to rotate and drive the first guide rod 503 to move: as the first rotating disk 502 rotates, the first guide rod 503 at the edge of its surface will also move accordingly. Since the first guide rod 503 is fixed on the first rotating disk 502, it will move along a circular path. During the movement, the first guide rod 503 will pass through and push the first limiting rod 504. The top end of the first limiting rod 504 is fixedly connected to the driving toothed disc 507. Therefore, when the first limiting rod 504 is pushed, it will drive the driving toothed disc 507 to rotate around its rotating shaft 509. The rotation of the driving toothed disc 507 will cause it to mesh with the first rack 508 fixed on the side wall of the filter plate 103. Due to the meshing relationship between the two, the rotation of the driving gear disc 507 will be converted into the linear motion of the first rack 508, thereby driving the filter plate 103 to slide back and forth along its inclined direction in the slide groove 505 of the support frame 100. As the filter plate 103 slides back and forth, the biomass fuel is evenly spread on the filter plate 103 and fully contacts the filter medium, thereby achieving further impurity removal.

[0050] Reference Figure 11-Figure 12 As shown, the cleaning mechanism 400 includes: a sliding rod 401, a cleaning plate 402 and a cleaning head 403; wherein, the sliding rod 401 is provided with two groups and is slidably arranged on the two inner walls of the filter plate 103 away from each other, and a plurality of groups of cleaning heads 403 are fixedly arranged at intervals between the two groups of sliding rods 401, and a plurality of cleaning heads 403 in contact with the upper surface of the filter plate 103 are fixedly arranged on the bottom surface of each group of cleaning heads 403, and a second driving member for driving the sliding rod 401 to slide along the inner wall of the filter plate 103 is fixedly arranged.

[0051] In the above scheme, when the biomass fuel begins to accumulate on the filter plate 103 and needs to be cleaned, the second driving member is started, and the second driving member transmits power to the slide bar 401 through its transmission mechanism, thereby driving the slide bar 401 to slide along the inner wall of the filter plate 103. Since multiple groups of cleaning heads 403 are fixedly arranged between the slide bars 401, these cleaning heads 403 will also move with the sliding of the slide bars 401. As the cleaning heads 403 move on the upper surface of the filter plate 103, they will continuously contact the filter plate 103 and scrape or brush off the impurities and residues attached thereto. Since multiple cleaning heads 403 are fixedly arranged on the bottom surface of each group of cleaning heads 403, it can be ensured that each position on the surface of the filter plate 103 can be fully cleaned, and the continuous operation of the second driving member will continuously drive the slide bar 401 and the cleaning heads 403 to slide on the filter plate 103 and clean its surface until the biomass fuel is completely cleaned and the surface of the filter plate 103 is restored to cleanliness.

[0052] Reference Figure 12-13 As shown, the second driving member includes: a second rotating disk 405, a second guide rod 406 and a second limiting rod 407; wherein, the second rotating disk 405 is rotatably arranged on the inner wall of the support frame 100 and its rotating shaft is connected to the output shaft of the driving motor 501 through a transmission belt 404, and a second guide rod 406 is fixedly arranged on the surface of the second rotating disk 405 along its circumferential direction, and a long strip of second limiting rod 407 is slidably sleeved on the second guide rod 406, and the second limiting rod 407 is fixedly connected to the top of the sliding rod 401.

[0053] When in use, the drive motor 501 located on the side wall of the support frame 100 is started, and the transmission belt 404 is used to provide power for the rotation of the second rotating disk 405. When the output shaft of the drive motor 501 rotates, the power is transmitted to the rotating shaft of the second rotating disk 405 through the transmission belt 404, so that it starts to rotate. As the second rotating disk 405 rotates, the second guide rod 406 fixedly arranged on its surface along the circumferential direction will also rotate. Since the second guide rod 406 is fixed on the second rotating disk 405, it will move along a circumferential path. A long second limiting rod 407 is slidably sleeved on the second guide rod 406, and there is relative sliding between the two but they remain connected. As the second guide rod 406 moves, the second limit rod 407 will slide along it, and because it is fixedly connected to the top of the slide rod 401, it will drive the slide rod 401 to slide along the inner wall of the filter plate 103. As the slide rod 401 slides, the cleaning head 403 thereon starts to work, cleaning the surface of the filter plate 103, scraping or brushing off the attached impurities and residues. The continuous operation of the drive motor 501 will continuously repeat the above process, so that the cleaning head 403 can continuously clean the surface of the filter plate 103 until the biomass fuel is completely removed and the surface of the filter plate is restored to cleanliness.

[0054] Reference Fig.13 As shown, the cleaning mechanism 400 also includes: a crushing piece for crushing impurities attached to the surface of the filter plate 103, wherein the crushing piece includes: a crushing roller 408, both ends of the crushing roller 408 are respectively rotatably arranged on the inner walls of the two groups of sliding rods 401, and one end thereof is fixedly sleeved with a gear 409, and the inner wall of the support frame 100 is fixedly provided with a second rack 410, and the gear 409 is meshed with the second rack 410.

[0055] In the above scheme, as the slide bar 401 slides, the surface of the filter plate 103 is preliminarily cleaned. At the same time, since the two ends of the crushing roller 408 are respectively rotatably arranged on the inner side wall of the slide bar 401, and one end of the crushing roller 408 is fixedly sleeved with a gear 409 meshing with the second rack 410, when the slide bar 401 moves, the gear 409 moves and rotates along the second rack 410. This rotational motion drives the crushing roller 408 to rotate together, and as the crushing roller 408 rotates, it contacts the impurities attached to the surface of the filter plate 103 and crushes them. The crushed impurities are more easily scraped off by the cleaning head 403 or flow away with the biomass fuel, thereby improving the impurity removal effect. The continuous operation of the drive motor 501 will continuously drive the slide rod 401, the cleaning head 403 and the crushing roller 408 to move and rotate on the filter plate 103, realizing a continuous cleaning and crushing process. By introducing crushing pieces, larger impurities attached to the surface of the filter plate 103 can be crushed into smaller particles, making it easier for them to be scraped off by the cleaning head 403 or flow away with the biomass fuel, thereby improving the impurity removal efficiency. The crushed impurity particles are smaller and are not easy to accumulate inside the filter plate 103 to cause blockage, thereby reducing the risk of equipment failure.

[0056] Reference Figure 2-Figure 3 As shown, the feeding mechanism 200 includes: a bracket 201, a material storage box 203 and a spacer feeding piece; wherein, the bracket 201 is fixedly arranged on the upper surface of the support frame 100, and a material storage box 203 for storing materials is fixedly arranged on the bracket 201, and a spacer feeding piece is slidably arranged on the bottom surface of the material storage box 203 at a position corresponding to its discharge port, and a feed port 209 for feeding is opened on the top surface of the screen drum 102 near one end of the spacer feeding piece.

[0057] When the biomass fuel impurity removal equipment starts to operate, the interval loading piece is started, which will drive the interval loading piece to slide on the bottom surface of the storage box 203 to control the intermittent and quantitative supply of the biomass fuel. As the interval loading piece slides, it will scrape a certain amount of biomass fuel from the discharge port of the storage box 203 and transport it to the feed port 209 of the screen cylinder 102. The design of the feed port 209 should ensure that the biomass fuel can smoothly enter the screen cylinder 102 for impurity removal. The biomass fuel entering the screen cylinder 102 will be impurity-removed under the rotation of the screen cylinder 102. The screen inside the screen cylinder 102 will remove impurities and unqualified particles in the biomass fuel, and the interval loading piece will continue to work, continuously transporting the biomass fuel from the storage box 203 to the screen cylinder 102 for impurity removal. At the same time, the screen drum 102 will continue to rotate to ensure sufficient impurity removal of the biomass fuel. The design of the interval feeding piece can realize intermittent and quantitative supply of the biomass fuel, avoiding the blockage of the screen drum 102 and the reduction of impurity removal effect caused by excessive feeding, thereby improving production efficiency.

[0058] Reference Figure 2-Figure 3 As shown, the interval loading member includes: a sliding unloading member 204, an electric telescopic rod 205 and a rotating plate 206; wherein, a sliding bracket 202 is fixedly provided on the bracket 201, the storage box 203 is fixedly provided on the upper surface of the sliding bracket 202, a sliding unloading member 204 is slidably provided on the bottom surface of the storage box 203 in the sliding bracket 202, a rotating plate 206 is rotatably provided on the bottom surface of the sliding unloading member 204, a support plate 207 is fixedly provided on the side of the sliding bracket 202 and located on the bottom surface of the rotating plate 206, a pressure sensor 208 is fixedly provided on the support plate 207, and an electric telescopic rod 205 is fixedly provided on the sliding bracket 202, the output end of the electric telescopic rod 205 is horizontally arranged and fixedly connected to the side of the sliding unloading member 204, and is electrically connected to the pressure sensor 208 through the main controller.

[0059] When the equipment starts to run, the main controller starts the electric telescopic rod 205 according to the preset parameters or operation instructions. The output end of the electric telescopic rod 205 starts to move horizontally, pushing the sliding material discharge member 204 to slide in the sliding bracket 202. As the sliding material discharge member 204 slides, the rotating plate 206 on its bottom gradually approaches the pressure sensor 208 on the support plate 207. When the rotating plate 206 contacts the pressure sensor 208 and applies sufficient pressure, the pressure sensor 208 sends a signal to the main controller. After receiving the signal, the main controller controls the driving mechanism of the rotating plate 206 to start, so that the rotating plate 206 rotates and opens, allowing the biomass fuel to fall. After the rotating plate 206 opens, the biomass fuel in the storage box 203 falls into the feed port 209 of the screen drum 102 through the opening of the sliding material discharge member 204 and the gap between the rotating plate 206. When the set discharge amount is reached or the electric telescopic rod 205 completes a telescopic stroke, the main controller controls the electric telescopic rod 205 to move in the opposite direction, driving the sliding material discharge member 204 back to the initial position. At the same time, the driving mechanism of the rotating plate 206 will also start, so that the rotating plate 206 rotates and closes to prevent the biomass fuel from continuing to fall. The above process will be repeated continuously to achieve intermittent and quantitative supply of biomass fuel. The main controller can adjust the extension frequency and amplitude of the electric telescopic rod 205 according to actual production needs and the feedback signal of the pressure sensor 208 to control the feeding speed and amount.

[0060] Reference Figure 6-Figure 7 As shown, the sieve drum 102 is provided with a rotating stirring mechanism 300 for stirring the incoming biomass fuel to separate it from impurities, and the rotating stirring mechanism 300 includes: a driving shaft 302, a fixing ring 303 and a stirring driving rod 304; wherein, the driving shaft 302 is rotatably arranged on the fixing disk 101, and a plurality of groups of stirring driving rods 304 are fixedly arranged at intervals on the driving shaft 302, and the end of the stirring driving rod 304 away from the driving shaft 302 is fixedly connected to the fixing ring 303, and the fixing ring 303 is coaxially fixed to the inner side wall of the sieve drum 102, and a rotating motor 301 is fixedly arranged at the top of the fixing disk 101, and the top end of the output shaft of the rotating motor 301 is fixedly connected to the driving shaft 302 through a shaft coupling.

[0061] In the above scheme, after the biomass fuel enters the screen drum 102 through the feeding mechanism 200, the rotating motor 301 is started. The output shaft of the rotating motor 301 is fixedly connected to the drive shaft 302 through a shaft coupling, so the rotational motion of the rotating motor 301 will be directly transmitted to the drive shaft 302. As the drive shaft 302 rotates, the multiple groups of stirring drive rods 304 fixedly arranged thereon will also start to rotate. These stirring drive rods 304 form a certain stirring area inside the screen drum 102 to stir the biomass fuel entering. The rotational motion of the stirring drive rods 304 will drive the biomass fuel to roll and mix inside the screen drum 102, so that the biomass fuel and the impurities therein are fully contacted and separated. At the same time, the stirring action can also promote the uniform distribution of the biomass fuel in the screen drum 102 and improve the impurity removal effect. The continuous operation of the rotating motor 301 will continuously drive the stirring drive, and the stirring drive rods 304 rotate and stir until the impurities in the biomass fuel are fully separated and discharged from the outside of the screen drum 102.

[0062] Reference Figure 4 and Figure 6 As shown, an arc-shaped material guide plate 104 is fixedly and obliquely disposed on the top of the filter plate 103 , and a collecting box 105 is movably disposed on the bottom surface of the filter plate 103 .

[0063] In the above scheme, after the biomass fuel passes through the screen cylinder 102, it will fall on the filter plate 103. The screen or filter medium on the filter plate 103 will filter the biomass fuel to remove impurities and unqualified particles therein. Since the guide plate 104 is inclined and arc-shaped, it can guide the biomass fuel after impurities to slide along its surface and collect it. As the biomass fuel continues to enter and the filtering process continues, impurities will continue to fall from the filter plate 103 and be collected by the collection box 105.

[0064] In summary, the present invention provides a biomass fuel production impurity removal device. When in use, the biomass fuel is directed to be loaded into the screen drum 102 through the loading mechanism 200. The screen drum 102 is tilted and rotatable on the fixed plate 101 to perform preliminary impurity removal on the fuel. The fuel after preliminary impurity removal falls on the filter plate 103 below for further impurity removal. The sliding mechanism 500 makes the filter plate 103 slide back and forth on the support frame 100 along its tilt direction to increase the impurity removal effect. The cleaning mechanism 400 cleans the surface of the filter plate 103 during the impurity removal process to prevent clogging. Finally, the pure biomass fuel falls through the guide plate 104 for collection, realizing the double impurity removal of the biomass fuel and improving the impurity removal efficiency and quality.
