[0017] This invention provides a biomass pellet fuel forming device with an integrated pellet filtering function. It has the following beneficial effects:

[0018] 1. This biomass pellet fuel forming device with integrated crushing and filtering function addresses the common problem in conventional equipment where raw materials tend to stick to the inside of the equipment and extrusion tools during the extrusion process, and also tend to stick to crushed materials after extrusion due to insufficient moisture drying. The cutting and processing mechanisms resolve these issues, facilitating the forming process of the raw materials.

[0019] 2. This biomass pellet fuel forming device with attached material filtration function, through the setting of a transport mechanism, addresses the issue that during the extrusion process, the raw material is not fully formed and easily adheres to external debris. Therefore, air is supplied to the raw material extruded from different heights to accelerate the forming process and prevent the extruded raw material from mixing with debris. This achieves the purpose of facilitating the air supply and drying of the extruded raw material.

[0020] 3. This biomass pellet fuel forming device with attached material filtration function, through the setting of a cutting mechanism, facilitates the adjustment of the cutting height according to the position of the extrusion nozzle when cutting the extruded raw material, and simultaneously cuts the raw material extruded from both sides. Driven by the second electric telescopic column, it promotes the separation of raw material fragments. This achieves the purpose of facilitating the cutting and transportation of extruded raw materials.

[0021] 4. This biomass pellet fuel forming device with integrated crushing and filtering function, through its processing mechanism, selects a suitable forming hole size according to the size requirements of the raw material, and performs extrusion processing in conjunction with the forming hole. During the extrusion process, it prevents the raw material from sticking to the inner wall of the feed cylinder, thus avoiding interference with subsequent extrusion processing and reducing material waste. This achieves the goal of facilitating the extrusion of raw materials and controlling the extrusion into different forming sizes. Attached Figure Description

Detailed Implementation

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0032] like Figures 1-8 As shown, the present invention provides a technical solution, specifically including:

[0033] The base 1 has a collection cylinder 2 and a second electric telescopic column 13 fixedly connected to its top. The collection cylinder 2 has a connecting ring 3 fixedly connected to its outside. The top of the connecting ring 3 has a first electric telescopic column 7 fixedly connected to its top. The top of the first electric telescopic column 7 has a feeding cylinder 8 fixedly connected to its top. The top of the second electric telescopic column 13 has an annular box 4 fixedly connected to its top. The top of the annular box 4 has a transport mechanism 5 fixedly connected to its top.

[0034] The cutting mechanism 6 is used to cut and transport the extruded raw material. The cutting mechanism 6 includes a fixed rod 601, a first circular plate 602 is fixedly connected to the outside of the fixed rod 601, a rotating assembly 604 is fixedly connected to the top of the annular box 4, and the fixed rod 601 is fixedly connected to the inside of the connecting ring 3.

[0035] The processing mechanism 9 is used to sort the raw materials and extrude them. The processing mechanism 9 includes a second multi-stage electric push rod 901. A lifting ring plate 902 is fixedly connected to the top of the second multi-stage electric push rod 901. A vertical plate 903 is fixedly connected to the top of the lifting ring plate 902. An extrusion assembly 904 is fixedly connected to the outside of the vertical plate 903. The second multi-stage electric push rod 901 is fixedly connected inside the collecting cylinder 2.

[0036] An outer cover 10 is fixedly connected to the top of the annular box 4, and a lifting frame 11 is fixedly connected to the top of the feeding cylinder 8. A first electric push plate 12 is fixedly connected to the bottom of the lifting frame 11. This design facilitates the extrusion molding of raw materials and the filtering and collection of fragments. Before using the equipment, the second electric telescopic column 13 is activated, which drives the annular box 4 upward. The raw material is fed into the feeding cylinder 8. After feeding, the first electric push plate 12 is activated to extrude the raw material. Subsequently, the processing mechanism 9 is activated to process and extrude the raw material until it enters the space between the annular box 4 and the outer cover 10. The cutting mechanism 6 and the transport mechanism 5 are activated periodically to cut and transport the extruded raw material. After cutting, the second electric telescopic column 13 is repeatedly opened and closed, causing the annular box 4 to move up and down, promoting the outward movement of the cut raw material and causing the fragments to vibrate. During this process, the fragments gradually enter the collection cylinder 2 and the annular box 4.

[0037] The transport mechanism 5 includes a fan box 501, a fan is fixedly connected inside the fan box 501, a telescopic pipe 502 is fixedly connected inside the fan box 501, a fixing ring 503 is fixedly connected outside the telescopic pipe 502, an inclined pipe is fixedly connected inside the telescopic pipe 502, and the fan box 501 is fixedly connected inside the outer cover 10.

[0038] The outer cover 10 is internally fixedly connected to a third electric telescopic column 504, and the bottom of the third electric telescopic column 504 is fixedly connected to an electric telescopic curved rod 505, which is fixedly connected to a fixing ring 503.

[0039] The upper surface of the annular box 4 is inclined, with a lower position near the flow channel 506. The flow channel 506 is located inside the outer cover 10, and a fixing plate 507 is fixedly connected inside the flow channel 506. A first electric push rod 508 is fixedly connected to the bottom of the fixing plate 507, and an arc-shaped locking plate 509 is fixedly connected to the bottom of the first electric push rod 508. This design facilitates air drying of the extruded raw material. When the first electric push rod 508 is activated, it moves the arc-shaped locking plate 509 downwards, protecting the raw material at the top of the annular box 4. During the cutting process, the fan in the fan box 501 is activated, and the air from the fan moves downwards through the telescopic pipe 502 to the inclined pipe, and then to the outside of the feed cylinder 8. Based on the extrusion position of the raw material, the third electric telescopic column 504 and the electric telescopic bending rod 505 are activated, thereby controlling the position of the fixing ring 503. The fixing ring 503 drives the telescopic tube 502 to move, thereby controlling the air outlet position to dry the extruded raw material and also causing the broken material to move downwards. After being extruded, the raw material gradually moves into the interior of the outer cover 10, and the rotating component 604 is activated to cut the extruded raw material. Subsequently, the raw material falls downwards above the annular box 4, and the broken material moves downwards through the filter hole 605 into the interior of the annular box 4. The broken material in the feed cylinder 8 moves downwards through the gap between the fixing rod 601 and the first circular plate 602 into the bottom collection cylinder 2.

[0040] The connecting ring 3 has a slot 603 inside, which is fixedly connected to the first electric telescopic column 7. The connecting ring 3 has several filter holes 605 inside. The rotating component 604 includes a fixed column 6041. A fixed cylinder 6042 is fixedly connected to the top of the fixed column 6041. A first multi-stage electric push rod 6043 is fixedly connected inside the fixed cylinder 6042. The fixed column 6041 is fixedly connected inside the connecting ring 3.

[0041] A motor housing 6044 is fixedly connected to the top of the first multi-stage electric push rod 6043. A servo motor is fixedly connected inside the motor housing 6044. A diverter joint 6045 is fixedly connected to the output end of the servo motor. An adjusting rod 6046 is rotatably connected inside the diverter joint 6045. A blade 6047 is fixedly connected to the outside of the adjusting rod 6046. This design facilitates the cutting and transport of extruded raw materials. Depending on the position of the extruded material, the first multi-stage electric push rod 6043 is activated, causing the motor housing 6044 to move upwards, which in turn causes the servo motor inside the motor housing 6044 to move upwards. The servo motor is then activated, causing the external diverter joint 6045, adjusting rod 6046, and blade 6047 to rotate left and right. The blade 6047 then begins to cut the raw material extruded by the processing mechanism 9 from side to side.

[0042] The top of the lifting ring plate 902 is fixedly connected to the partition plate 906. The inside of the feed cylinder 8 is provided with forming holes 905. There are two sets of forming holes 905, and each set of forming holes 905 is provided with three different sizes. The inside of the lifting ring plate 902 is provided with several filter ports.

[0043] Based on the raw material forming dimensions, the second multi-stage electric push rod 901 is activated, driving the lifting annular plate 902 upward. Excess forming holes 905 are manually plugged using a stopper. After the raw material enters the feed cylinder 8, the extrusion assembly 904 is activated to extrude and shape the material, which gradually moves outward through the forming holes 905. The broken material moves downward through the filter port into the collection cylinder 2.

[0044] The extrusion assembly 904 includes a fixed box 9041, a second fan is fixedly connected inside the fixed box 9041, a horizontal pipe 9042 is fixedly connected inside the fixed box 9041, an air outlet is provided at the bottom of the horizontal pipe 9042, and the fixed box 9041 is fixedly connected to the top of the feed cylinder 8.

[0045] The vertical plate 903 has a groove 9043 inside, and a second electric push plate 9044 is fixedly connected inside the groove 9043. The second electric push plate 9044 has a fixing groove 9045 inside, and an electric telescopic rod 9046 is fixedly connected inside the fixing groove 9045. A sliding plate 9047 is fixedly connected to the outside of the electric telescopic rod 9046. A second electric push rod 9048 is fixedly connected inside the sliding plate 9047. A rigid spring 9049 is fixedly connected to the outside of the second electric push rod 9048. A second circular plate is fixedly connected to the outside of the rigid spring 9049. This design facilitates the extrusion of raw materials and allows control over the extrusion into different molding sizes. When the second electric push plate 9044 is activated, it begins to move outward. Simultaneously, the electric telescopic rod 9046 is activated, causing the sliding plate 9047 to move outward. At this point, the two sliding plates 9047 correspond to the molding holes 905. The second electric push rod 9048 is activated, which drives the rigid spring 9049 and the second circular plate to move outward, extruding the raw material into the forming hole 905.

[0046] The second electric push rod 9048 is turned on and off at regular intervals to control the extrusion amount of raw materials. During the extrusion process, the second fan in the fixed box 9041 is turned on, and the air in the second fan moves downward through the air outlet at the bottom of the horizontal pipe 9042 to prevent the broken material from sticking to the inner wall of the feed cylinder 8.

[0047] Working principle: Before using the equipment, activate the second electric telescopic column 13, which will drive the annular box 4 to move upward. According to the forming size of the raw material, activate the second multi-stage electric push rod 901, which will drive the lifting annular plate 902 to move upward. Manually use the plug to block any excess forming holes 905.

[0048] The raw material is fed into the feed cylinder 8. After feeding is completed, the first electric push plate 12 is activated, moving downwards to squeeze the raw material and expel excess water. The extrusion assembly 904 is then activated, followed by the second electric push plate 9044, which begins to move outwards. Simultaneously, the electric telescopic rod 9046 is activated, driving the sliding plate 9047 outwards. At this point, the two sliding plates 9047 align with the forming hole 905. The second electric push rod 9048 is then activated, driving the rigid spring 9049 and the second circular plate outwards, squeezing the raw material into the forming hole 905.

[0049] The second electric push rod 9048 is turned on and off at regular intervals to control the extrusion amount of raw material. During the extrusion process, the second fan in the fixed box 9041 is turned on, and the air from the second fan moves downward through the air outlet at the bottom of the horizontal pipe 9042 to prevent the material fragments from sticking to the inner wall of the feed cylinder 8. The material fragments and excess water move downward through the filter port to the collection cylinder 2. Then, the first electric push plate 12 is turned on again, and the first electric push plate 12 moves downward to extrude the raw material, so that the raw material is on the lifting annular plate 902, and the extrusion assembly 904 is turned on. The operation is repeated to extrude the raw material.

[0050] After the raw material is extruded, it gradually moves into the interior of the outer casing 10. The cutting mechanism 6 and the transport mechanism 5 are activated periodically to cut and transport the extruded material. The rotating assembly 604 is activated to cut the extruded material. The first multi-stage electric push rod 6043 is activated, driving the motor housing 6044 upwards, which in turn drives the servo motor inside the motor housing 6044 upwards. The servo motor is activated, driving the external steering joint 6045, adjusting rod 6046, and blade 6047 to rotate left and right. The blade 6047 begins to cut the raw material extruded by the processing mechanism 9. The raw material then falls downwards above the annular box 4, and the fragments move downwards through the filter holes 605 into the interior of the annular box 4. The fragments in the feed cylinder 8 move downwards through the gap between the fixing rod 601 and the first circular plate 602 into the bottom collection cylinder 2. The first electric push rod 508 is activated, driving the arc-shaped locking plate 509 downwards to protect the raw material at the top of the annular box 4. During the cutting process, the fan in the fan box 501 is turned on. The air from the fan moves downward through the telescopic pipe 502 to the inclined pipe, and then to the outside of the feed cylinder 8. Depending on the position where the raw material is extruded, the third electric telescopic column 504 and the electric telescopic bending rod 505 are activated, thereby controlling the position of the fixing ring 503. The fixing ring 503 drives the telescopic pipe 502 to move, thereby controlling the position of the air outlet, which dries the extruded raw material and also drives the broken material downward.

[0051] After cutting, the second electric telescopic column 13 is repeatedly opened and closed. The second electric telescopic column 13 drives the annular box 4 to move up and down, promoting the outward movement of the cut raw material and causing the fragments to vibrate. During this process, the fragments gradually enter the collecting cylinder 2 and the annular box 4.

[0052] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
