Description

Technical Field

[0001] The present invention relates to the technical field of molding and granulation, and more specifically, to a molding and granulation device for processing biomass pellet fuel. Background Art

[0002] Biomass fuel: It refers to using biomass materials as fuel, generally mainly agricultural and forestry waste. It is mainly different from fossil fuels. Directly burning biomass is a highly polluting fuel and is only used in large stoves in rural areas and is not allowed to be used in cities. The application of biomass fuel is actually mainly biomass formed fuel, which uses agricultural and forestry waste as raw materials and is made into various formed and directly combustible new clean fuels through processes such as crushing, mixing, extrusion, and drying.

[0003] In the processing of biomass pellet fuel, the raw materials need to go through a series of delicate steps such as crushing, drying, forming, and cooling, and require close cooperation among various equipment. Especially in the forming stage, the dried raw materials are sent into the granulator via a conveyor belt. Inside the granulator, the raw materials gradually soften under the combined action of high pressure and friction and are finally shaped into particles. However, in the current production process, the equipment in the mechanical processing system often lacks sufficient coordinated operation, which directly leads to the difficulty in maintaining the continuity of the processing process, thus restricting the production efficiency. More critically, the connection between multiple devices often requires a large amount of manual intervention, which not only greatly increases the production cost but also brings uncertainty to the production quality of pellet fuel and is difficult to ensure precise quality control. In view of this, we propose a molding and granulation device for processing biomass pellet fuel. Summary of the Invention

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] 1. By designing a transmission assembly, a gear assembly, an adjustment assembly, and a telescopic assembly, when the transmission assembly contacts the gear assembly, the transmission assembly will squeeze the telescopic assembly, thereby pushing the adjustment assembly to move to the right. When the transmission assembly does not contact the gear assembly, the return spring in the telescopic assembly will pull the adjustment assembly back to its original position, making it contact both the gear assembly and the elastic assembly at the same time. On the one hand, the entire switching process above does not require manual control, and the high-speed and low-speed operating states inside the device are automatically and repeatedly switched completely by the continuous operation of the motor. On the other hand, the device collects and pushes the material to the top, allowing it to fall naturally, thereby realizing the turning of the material. At the same time, with the continuously discharged drying gas, the material can be dried more quickly. The cooperation between this turning process and the drying gas further guarantees the quality of the device when processing biomass pellet fuel. This design greatly reduces the human resources required for the device, thereby saving a large amount of production costs.

[0025] 2. The present invention also designs a transmission assembly, a gear assembly, and an elastic assembly. When the motor operates, it will drive the slide rod to move through the sliding sleeve. At the same time, as the third gear rotates, the bump on its surface will drive the pulley to move reciprocally, which makes the elastic telescopic rod in a state of rapid extension and contraction. In this state, the sieve plate will move reciprocally left and right, thereby screening the raw material of biomass pellet fuel. On the one hand, the sieve plate moves at high speed and rotates 180 degrees to the upper part inside the second housing, which can ensure that the raw material of biomass pellet fuel closely adheres to the surfaces of the stirring plate and the scraping plate under the action of centrifugal force, thereby ensuring that the material can be effectively carried to the upper part inside the second housing, further improving the turning effect of the material. At the same time, during this process, the stirring plate will disengage from the bottom of the second housing, thus avoiding unnecessary contact between the sieve plate and the stirring plate and the scraping plate during the turning process. This not only extends the service lives of the sieve plate, the stirring plate, and the scraping plate, but also ensures the screening quality of the sieve plate for the raw material of biomass pellet fuel.

[0026] 3. The present invention also designs a gear assembly and a transmission assembly. Since the second gear will drive the first gear to rotate through the rotating shaft during rotation, when the first gear contacts the toothed plate, the toothed plate will contract due to extrusion and be in a low-speed flipping state during the flipping process, thus ensuring the material collection effect, avoiding rubbing against the sieve plate during high-speed operation, and ensuring that when the toothed plate contacts the first gear, the third gear will separate from the second gear and the pulley, ensuring the stability of the device operation.

[0045] As Figures 1 to 8 shown, a forming and granulating device for processing biomass pellet fuel according to the present invention includes

[0046] The production mechanism 1 includes a first outer shell 101, a stirring assembly 102 connected to the first outer shell 101, a discharge shell 103 located below the stirring assembly 102, a slide plate 104 located above the stirring assembly 102, a bracket 106, a bottom plate 105, an elastic assembly 107, and a connection port 108. Among them, the first outer shell 101 and the stirring assembly 102 are connected to the bottom plate 105 through the bracket 106. The elastic assembly 107 is located inside the discharge shell 103, and the connection port 108 is arranged outside the stirring assembly 102. And, the driving mechanism 2 includes a motor 201, a mounting frame 202 located below the motor 201, a telescopic assembly 203 connected to the motor 201, four transmission assemblies 204 arranged outside the telescopic assembly 203, a gear assembly 205, and an adjustment assembly 206. Among them, the gear assembly 205 is connected to one of the transmission assemblies 204, and the adjustment assembly 206 is connected to the telescopic assembly 203. When the transmission assembly 204 contacts the gear assembly 205, the transmission assembly 204 squeezes the telescopic assembly 203, causing the telescopic assembly 203 to push the adjustment assembly 206 to move to the right, so that the adjustment assembly 206 is in a misaligned state with the gear assembly 205 and the elastic assembly 107. At this time, the stirring assembly 102 is in a high-speed operation state, ensuring that the material can quickly turn 180 degrees inside the stirring assembly 102 and reach the top inside the stirring assembly 102. With the continuous operation of the motor 201, when the transmission assembly 204 does not contact the gear assembly 205, the return spring inside the telescopic assembly 203 will pull the adjustment assembly 206 to move backward, so that the adjustment assembly 206 contacts the gear assembly 205 and the elastic assembly 107 at the same time. At this time, the stirring assembly 102 is in a low-speed rotation state, so as to collect the material inside the stirring assembly 102, and the elastic assembly 107 will also be in a continuous shaking state to screen the dried material. Along with the continuous operation of the motor 201, the gear assembly 205 will also continuously switch between contacting the transmission assembly 204 and the adjustment assembly 206. On the one hand, the above process does not require manual control, and the high-speed and low-speed operation states inside the device are automatically and repeatedly switched by the continuous operation of the motor 201. On the other hand, by collecting and pushing the material to the top and making it fall naturally, the turning treatment of the material is realized, and with the continuously discharged drying gas, the material can be dried faster, and the turning treatment can further ensure the quality of the biomass pellet fuel processed by the device, reduce the human resources required by the device, and thus save a large amount of production costs.

[0047] In the embodiment of the present invention, the top of the first shell 101 is fixedly connected to the stirring component 102, the top of the stirring component 102 is slidably connected to the slide plate 104, the bottom of the stirring component 102 is connected to the discharge shell 103, the first shell 101 and the stirring component 102 are respectively fixedly connected to the four brackets 106, and the bottom ends of the four brackets 106 are fixedly connected to the top of the bottom plate 105, one end of the elastic component 107 is fixedly connected to the stirring component 102, the elastic component 107 is located in the discharge shell 103, the elastic component 107 is connected to the connection port 108, the bottom of the motor 201 is fixedly connected to the mounting frame 202, and the output shaft of the motor 201 is connected to the telescopic component 203 is fixedly connected, the telescopic component 203 is fixedly connected to four transmission components 204, one of the transmission components 204 is meshed with the gear component 205, the other end of the telescopic component 203 is fixedly connected to the adjustment component 206, the mounting frame 202 is fixedly connected to the outside of the first shell 101, the telescopic component 203 is clamped in the first shell 101, and the gear component 205 is clamped in the stirring component 102. When the motor 201 is running, the motor 201 will drive the slide bar 2034 through the sliding sleeve 2031, so that the slide bar 2034 drives the second gear 2054 to rotate through the third gear 2062, and at the same time, the second gear 2054 will also drive the connecting rod 2052 through the rotating shaft The shaft 1023 rotates. Since the diameter of the third gear 2062 is smaller than that of the second gear 2054, and the diameter of the second gear 2054 is larger than that of the first gear 2053, the connecting shaft 1023 will drive the stirring plate 1024 and the scraper 1025 to rotate at a high speed and rotate 180 degrees, so that the stirring plate 1024 is in a vertical upward state. At the same time, as the third gear 2062 rotates, the protrusion 2063 on its surface will also drive the pulley 1074 to move back and forth, so that the elastic telescopic rod 1076 is in a state of rapid extension and contraction. At this time, the screen plate 1071 moves back and forth left and right, thereby screening the biomass pellet fuel raw materials. The surface of the second shell 1021 moves at high speed one hundred and eighty degrees to the upper part of the interior of the second shell 1021, which can ensure that the biomass particle fuel raw materials are attached to the surfaces of the stirring plate 1024 and the scraper 1025 under the action of centrifugation, and ensure that the material can be carried to the upper part of the interior of the second shell 1021, thereby improving the material turning processing. At the same time, the stirring plate 1024 will be separated from the bottom of the second shell 1021 at this time, thereby avoiding the contact between the sieve plate 1071 and the stirring plate 1024 and the scraper 1025 during the turning process, ensuring the service life of the sieve plate 1071, the stirring plate 1024 and the scraper 1025, and can ensure the screening quality of the biomass particle fuel raw materials by the sieve plate 1071.

[0048] In an embodiment of the present invention, the stirring assembly 102 includes a second housing 1021. An inlet groove 1022 is formed above the second housing 1021. A partition plate is arranged inside the second housing 1021. A connecting shaft 1023 is clamped inside the second housing 1021. A stirring plate 1024 is fixedly connected to the outside of the connecting shaft 1023. The bottom end of the stirring plate 1024 is fixedly connected to a scraping plate 1025. The shape of the scraping plate 1025 is adapted to the shape of the inner wall of the second housing 1021. One side of the scraping plate 1025 and one side of the stirring plate 1024 are both fixedly connected to a leakage prevention plate 1026. A discharge port is arranged below the inner wall of the second housing 1021. The second housing 1021 is slidably connected to a sliding plate 104 through the inlet groove 1022. The connecting shaft 1023 is in transmission connection with a gear assembly 205. The gear assembly 205 is clamped inside the second housing 1021. One end of an elastic assembly 107 is fixedly connected to the outer wall of the second housing 1021. The second housing 1021 is fixedly connected to a first housing 101. The elastic assembly 107 includes a sieve plate 1071. One side of the sieve plate 1071 is fixedly connected to a reinforcing rod 1072. The other end of the reinforcing rod 1072 is fixedly connected to a reinforcing rib 1073. One side of the reinforcing rib 1073 is fixedly connected to a pulley 1074. A positioning plate 1075 is fixedly connected above the sieve plate 1071. One side of the positioning plate 1075 is fixedly connected to an elastic telescopic rod 1076. The other end of the elastic telescopic rod 1076 is fixedly connected to the second housing 1021. The sieve plate 1071 is slidably connected to the discharge port formed below the second housing 1021. The position of the pulley 1074 corresponds to the position of an adjusting assembly 206. Due to the arrangement of the stirring plate 1024, the leakage prevention plate 1026 and the scraping plate 1025, it is ensured that in the high-speed rotation state, the device can carry the biomass pellet fuel raw material and thus turn it to the upper part inside the second housing 1021. While in the low-speed rotation state, the device can collect the biomass pellet fuel raw material to the greatest extent and thus perform subsequent turning treatment, improving the automation degree of the device and reducing the use difficulty of the device.

[0049] As another embodiment of the present invention, the telescopic assembly 203 includes a sliding sleeve 2031, a connecting sleeve 2032 is sleeved outside the sliding sleeve 2031, four slots 2033 are provided outside the sliding sleeve 2031, a sliding rod 2034 is slidably connected inside the sliding sleeve 2031, four first inclined slots 2035 are provided outside the sliding rod 2034, a return spring is provided in the sliding sleeve 2031, one end of the sliding sleeve 2031 is fixedly connected to the corresponding end of the motor 201, the other end of the sliding rod 2034 passes through the sliding sleeve 2031 and is fixedly connected to the adjusting assembly 206, the outer wall of the sliding sleeve 2031 is fixedly connected to four transmission assemblies 204, the transmission assembly 204 includes a toothed plate 2041, the toothed plate 2041 is a quarter-circular toothed plate 2041, one side of the toothed plate 2041 is fixedly connected to the mounting block 2042, the other side of the mounting block 2042 is fixedly connected to a connecting rod 2043, the connecting rod 2043 is slidably connected inside the sleeve 2045, a second inclined slot 2044 is provided at the other end of the connecting rod 2043, a spring 2046 is sleeved outside the connecting rod 2043, both ends of the spring 2046 are fixedly connected to the connecting rod 2043 and the sleeve 2045 respectively, the sleeve 2045 is fixedly connected inside the sliding sleeve 2031, the toothed plate 2041 is located below the gear assembly 205, the connecting rod 2043 is lapped with the first inclined slot 2035 through the second inclined slot 2044. By providing a return spring in the sliding sleeve 2031, when the toothed plate 2041 separates from the first gear 2053 as the sliding sleeve 2031 rotates, the sliding rod 2034 gradually releases the extrusion on the connecting rod 2043, so that the connecting rod 2043 will reset under the action of the elastic force of the return spring. At this time, the connecting rod 2043 will pull the third gear 2062 to contact the second gear 2054 and the pulley 1074 at the same time, ensuring the stability of the operation of the device, and ensuring that the device can automatically reciprocate and switch between two operating states automatically.

[0050] As another embodiment of the present invention, the gear assembly 205 includes bearings 2051. The number of bearings 2051 is two, and the same rotating shaft 2052 is sleeved inside the two bearings 2051. A first gear 2053 and a second gear 2054 are fixedly connected to the outside of the rotating shaft 2052. The first gear 2053 is a semi-gear. The rotating shaft 2052 passes through the bearing 2051 and is in transmission connection with the connecting rod 2043. The two bearings 2051 are respectively clamped on one side of the inner wall of the second housing 1021 and one side of the partition plate arranged inside the second housing 1021. The first gear 2053 meshes with one of the toothed plates 2041. The adjusting assembly 206 includes a driving shaft 2061. A third gear 2062 is fixedly connected to the outside of the driving shaft 2061. A plurality of bumps 2063 are fixedly connected to one side of the third gear 2062. The position where the third gear 2062 is provided with bumps 2063 corresponds to the position of the pulley 1074. The driving shaft 2061 is fixedly connected to one end of the connecting rod 2043. The third gear 2062 is located below the second gear 2054. Since the second gear 2054 will drive the first gear 2053 to rotate through the rotating shaft 2052 during rotation, when the first gear 2053 contacts the toothed plate 2041, the toothed plate 2041 will contract due to being squeezed, thereby pushing the sliding rod 2034 into the sliding sleeve 2031 and the sleeve 2045. When the sliding rod 2034 enters the sleeve 2045 and pushes the connecting rod 2043, since the surface of the connecting rod 2043 is provided with an inclined groove, the connecting rod 2043 gradually moves to the right, thereby pushing the third gear 2062 to separate from the second gear 2054 and the pulley 1074. Since the diameter of the toothed plate 2041 is larger than that of the first gear 2053, at this time, the first gear 2053 will drive the rotating shaft 2052 to rotate at a low speed, and the stirring plate 1024 will gradually flip 180 degrees in the vertically upward state and then vertically downward, and is in a low-speed flipping state during the flipping process, so as to ensure the collection effect of the material, avoid rubbing against the sieve plate 1071 during high-speed operation, and ensure that when the toothed plate 2041 contacts the first gear 2053, the third gear 2062 will separate from the second gear 2054 and the pulley 1074, ensuring the stability of the operation of the device.

[0051] Working principle: This embodiment provides a forming and granulating device for processing biomass pellet fuel. When in use, an external dryer is connected to the stirring assembly 102 through the connection port 108, the slide plate 104 is opened, and the biomass pellet fuel raw material to be processed is put into the stirring assembly 102, and the motor 201 is started to process the biomass pellet fuel raw material;

[0052] When the motor 201 operates, it drives the movement of the slide bar 2034 through the sliding sleeve 2031. Then, the slide bar 2034 drives the second gear 2054 to rotate through the third gear 2062. At the same time, the second gear 2054 drives the connecting shaft 1023 to rotate through the rotating shaft 2052. Since the diameter of the third gear 2062 is smaller than that of the second gear 2054, and the diameter of the second gear 2054 is larger than that of the first gear 2053 (although the first gear 2053 is not directly involved in the movement in this section of the description, but mentioning it helps to understand the relative size relationship between the gears), therefore, the connecting shaft 1023 can drive the stirring plate 1024 and the scraping plate 1025 to rotate at a relatively high speed until they rotate 180 degrees, making the stirring plate 1024 in a vertically upward position. At the same time, as the third gear 2062 continues to rotate, the bump 2063 on its surface will push the pulley 1074 to move reciprocally, which causes the elastic telescopic rod 1076 to extend and contract rapidly. Under this action, the sieve plate 1071 will move reciprocally left and right, thus effectively screening the biomass pellet fuel raw materials;

[0053] During the rotation process, the second gear 2054 drives the first gear 2053 to rotate through the rotating shaft 2052. When the first gear 2053 contacts the toothed plate 2041, the toothed plate 2041 will contract due to being squeezed, and then push the slide bar 2034 to move into the sliding sleeve 2031 and the inside of the sleeve 2045. Once the slide bar 2034 enters the sleeve 2045 and contacts the connecting rod 2043, since the surface of the connecting rod 2043 is designed with an inclined groove, this makes the connecting rod 2043 gradually move to the right after being stressed. As the connecting rod 2043 moves, it will push the third gear 2062 to separate from the second gear 2054 and the pulley 1074 connected to it. It should be noted that since the diameter of the toothed plate 2041 is larger than that of the first gear 2053, when the toothed plate 2041 contacts and squeezes the first gear 2053, the first gear 2053 and the rotating shaft 2052 connected to it will turn into a low-speed rotation state. In this low-speed state, the stirring plate 1024 originally in the vertically upward position will gradually flip 180 degrees and become vertically downward, and keep rotating at a low speed during the whole flipping process.
