Description

Technical Field

[0001] This invention relates to the field of rice husk carbonization processing technology, and in particular to a feeding device for environmentally friendly rice husk carbonization processing. Background Technology

[0002] Rice husks are a major byproduct widely used in grain processing. Due to their large output, wide availability, and low cost, rice husks are considered a renewable resource. However, rice husks have a hard surface, contain high levels of silicon, and are not easily decomposed by bacteria. Furthermore, their low density can place a burden on the environment when disposed of as waste. Therefore, carbonization of rice husks is necessary to transform this waste resource into valuable products, thereby reducing environmental pollution and resource waste.

[0003] In the environmentally friendly carbonization process of rice husks, a feeding hopper is typically used to load and transport the rice husks to the carbonization equipment. For example, Chinese patent CN216187874U discloses a feeding device for environmentally friendly rice husk carbonization. This device uses a conical turntable within the feeding hopper to reduce clogging at the bottom outlet. However, this turntable design is prone to clogging due to damp rice husks adhering to its surface, causing blockage between the turntable and the feeding hopper and preventing discharge from the bottom outlet, thus reducing feeding efficiency. Therefore, this invention proposes a feeding device for environmentally friendly rice husk carbonization. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that the transfer table in the feeding device for environmentally friendly rice husk carbonization processing is prone to adhesion and blockage due to damp rice husks, resulting in low feeding efficiency. Therefore, this invention proposes a feeding device for environmentally friendly rice husk carbonization processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A feeding device for environmentally friendly rice husk carbonization processing includes a feeding hopper with inlet and outlet ports. A conical feeding platform is provided inside the feeding hopper. A gap is reserved between the outer edge corresponding to the bottom of the feeding platform and the inner wall of the feeding hopper. A positioning rod is vertically connected between the top and bottom of the feeding platform. A positioning element is connected between the positioning rod and the top of the feeding hopper. The surface of the positioning rod has multiple circumferentially distributed air blowing sections located above the top of the feeding platform. A pipe cavity communicating with the air blowing sections is provided inside the positioning rod. An air inlet communicating with the inside of the pipe cavity is provided at the top of the positioning rod.

[0006] Preferably, the feeding hopper includes an upper part, a middle part, and a lower part, which are interconnected from top to bottom. The top diameter of the middle part gradually decreases to the bottom diameter. The top diameter and bottom diameter of the upper part are both equal to the top diameter of the middle part, and the top diameter and bottom diameter of the lower part are both equal to the bottom diameter of the middle part.

[0007] Preferably, the positioning element includes a circular connecting block fixed on the positioning rod, and a plurality of L-shaped brackets arranged in a circular pattern are fixed between the surface of the circular connecting block and the top of the feeding hopper.

[0008] Preferably, the air blowing part includes an inclined air blowing pipe connected to the surface of the positioning rod. A solenoid valve one is installed on the surface of the inclined air blowing pipe, and a solenoid valve two is installed on the surface of the positioning rod, located below the top port of the inclined air blowing pipe. A pair of mounting blocks are fixed inside the inclined air blowing pipe, and guide rods are fixed inside the two mounting blocks. A heating wire is wound on the guide rods, and a protective net is provided at one end of the inclined air blowing pipe corresponding to the surface of the feeding platform.

[0009] Preferably, the bottom of the feeding platform is provided with a weight reduction groove, the inner top wall diameter of the weight reduction groove gradually increases to the bottom port diameter, and the top diameter of the feeding platform gradually increases to the bottom diameter. The connection between the feeding platform and the surface of the positioning rod is a sliding connection.

[0010] Preferably, when the connection between the feeding platform and the surface of the positioning rod is a sliding connection, a lifting mechanism for supporting the feeding platform is included.

[0011] Preferably, the lifting mechanism includes a connecting cylinder that is laterally connected to the positioning rod and communicates with the pipe cavity. The top of the connecting cylinder extends with an annular edge fixed to the positioning rod, and a spring is sleeved on the positioning rod and fixed between the top of the annular edge and the top wall of the weight reduction groove.

[0012] Preferably, a connecting shaft is rotatably provided between the two ends of the connecting cylinder, and multiple impellers arranged in a circular pattern and located inside the connecting cylinder are fixed on the connecting shaft. Circular rotating plates are fixed at both ends of the connecting shaft, and a pair of arc-shaped protrusions are fixed on the circular rotating plates. A top plate fixed to the top wall of the weight reduction groove is attached to the surface of the circular rotating plates.

[0013] Preferably, the bottom end of the positioning rod is provided with an air outlet that communicates with the inside of the pipe cavity, and a limiting ring is fixed to the bottom edge of the positioning rod. A material unloading component that is linked with the circular rotating plate slides between the top and bottom of the limiting ring.

[0014] Preferably, the material feeding component includes a material feeding rod slidably connected between the top and bottom of the limiting ring, one end of the material feeding rod corresponding to the bottom outlet of the feeding hopper, and the other end of the material feeding rod is fixed with a semi-circular block that fits against the surface of the circular rotating plate. A spring is sleeved on the surface of the material feeding rod and fixed between the top of the limiting ring and the bottom of the semi-circular block.

[0015] Compared with the prior art, the present invention provides a feeding device for environmentally friendly processing of rice husk carbonization, which has the following beneficial effects: 1. This feeding device for environmentally friendly rice husk carbonization processing, through the coordinated design of pipe cavity, air inlet and inclined air blowing pipe, mounting block, guide rod, heating wire and protective net, is designed to blow hot air onto the rice husks adhering to the feeding platform. This allows the rice husks on the feeding platform to be better removed and dried from the surface under the airflow, preventing the rice husks from clogging the gap space formed between the feeding platform and the feeding hopper, ensuring smooth transportation of the rice husks, and thus improving the efficiency of environmentally friendly rice husk carbonization processing.

[0016] 2. The feeding device for the environmentally friendly processing of rice husk carbonization is designed with a spring, impeller, connecting shaft, circular rotating plate, arc-shaped protrusion and top plate to make the feeding platform shake up and down repeatedly. In this way, the rice husks adhering to the feeding platform are more easily dispersed and fall off the feeding platform under the combination of up and down shaking and airflow, which further promotes and improves the smoothness of rice husk conveying.

[0017] 3. The feeding device for the environmentally friendly processing of rice husk carbonization consists of a material unblocking component composed of a comb rod, a semi-circular block, and a spring. With the cooperation of a circular rotating plate and an arc-shaped protrusion, the material unblocking component moves the comb rod back and forth in the lower part. This helps to unblock the rice husks in the lower part during transportation, ensuring smoother feeding and transportation of rice husks from the hopper. Attached Figure Description

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0022] The following is in conjunction with the appendix Figure 1 -Appendix Figure 8 The technical solutions provided in the various embodiments of the present invention will be described in detail.

[0023] Reference Figures 1-8A feeding device for environmentally friendly rice husk carbonization processing includes a feeding hopper 1 with inlet and outlet ports. The feeding hopper 1 comprises an upper part 101, a middle part 102, and a lower part 103, which are interconnected from top to bottom. The top diameter of the middle part 102 gradually decreases to the bottom diameter. The top and bottom diameters of the upper part 101 are equal to the top diameter of the middle part 102, and the top and bottom diameters of the lower part 103 are equal to the bottom diameter of the middle part 102. A conical feeding platform 2 is provided inside the feeding hopper 1, and the outer edge corresponding to the bottom of the feeding platform 2 is located between the feeding hopper and the bottom of the feeding platform 2. A gap space is reserved between the inner walls of 1. The positioning rod 3 is vertically connected between the top and bottom of the feeding platform 2. The positioning rod 3 is connected to the top of the feeding hopper 1 with a positioning component 4. The positioning component 4 includes a circular connecting block 41 fixed on the positioning rod 3. Multiple L-shaped brackets 42 are fixed between the surface of the circular connecting block 41 and the top of the feeding hopper 1. The surface of the positioning rod 3 is provided with multiple air blowing parts 5 that are distributed in a circle and located above the top of the feeding platform 2. The positioning rod 3 is provided with a pipe cavity 6 that communicates with the air blowing part 5. The top of the positioning rod 3 is provided with an air inlet 7 that communicates with the inside of the pipe cavity 6.

[0024] This technical solution is adopted because the feeding platform 2 inside the feeding hopper 1 is prone to damp rice husks adhering to its surface, causing the rice husks to clog the gap between the feeding platform 2 and the feeding hopper 1. This prevents the rice husks from being discharged from the bottom outlet of the feeding hopper 1, reducing feeding efficiency. Therefore, to address this problem, a pipe cavity 6 is provided inside the positioning rod 3, with an air inlet 7 at the top that communicates with the pipe cavity 6. Then, multiple air blowing sections 5 are provided on the positioning rod 3, corresponding to the feeding platform 2. In this technical solution, the air blowing section 5 is an inclined air blowing pipe 51. When the air inlet 7 is connected to an external air pump, the external air pump can provide sufficient air pressure to ensure that the air blowing section 5 can generate sufficient blowing force to effectively remove the rice husks adhering to the feeding platform 2. This ensures that the rice husks can be smoothly discharged from the gap space formed between the feeding platform 2 and the feeding hopper 1 to the bottom outlet of the feeding hopper 1. With the setting of the air blowing section 5, the problem of rice husk adhesion can be better handled, which helps to improve the efficiency and smoothness of the environmentally friendly carbonization processing of rice husks.

[0025] In the above scheme, the circular connecting block 41 is fixed to the positioning rod 3. The circular connecting block 41 is fixed to the top of the feeding hopper 1 in a circular manner by multiple L-shaped brackets 42. This is to enable the positioning rod 3 to stably limit and support the feeding platform 2. This can effectively prevent the positioning rod 3 from shaking, displacing or tilting during use, and ensure the stability of the feeding platform 2. The stable support structure helps the feeding platform 2 to be accurately positioned, so that the air blowing part 5 can accurately blow onto the surface of the feeding platform 2 to remove the rice husks adhering to the surface of the feeding platform 2.

[0026] Furthermore, with the top-to-bottom interconnected design of the feeding hopper 1, the rice husks can gradually flow downwards along the inner surface of the feeding hopper 1. Because the top and bottom diameters of the upper part 101 are equal to the top diameter of the middle part 102, it ensures that the material will not experience sudden changes or compression during its entry into the middle part 102, reducing the resistance to material movement and facilitating balanced material transport. Then, the rice husks entering the middle part 102 gradually decrease in diameter from top to bottom, which helps maintain the uniform flow of the rice husks and reduces blockage and accumulation during transport. This design promotes the uniform flow and distribution of rice husks within the feeding hopper 1, avoiding blockage and deviation. The feeding platform 2, located in the middle part 102 of the feeding hopper 1, gradually increases in diameter from top to bottom, and the gap space formed between the feeding platform 2 and the inner wall of the middle part 102 gradually decreases. This design ensures that the rice husks are better dispersed from the gap space to the bottom outlet of the feeding hopper 1, preventing the rice husks from accumulating at the bottom outlet of the feeding hopper 1 and causing uneven material discharge.

[0027] It should be noted that the gap between the feeding platform 2 and the middle part 102 gradually narrows from top to bottom. On the one hand, this makes the transition of rice husks from the bottom edge of the feeding platform 2 to the middle part 102 smoother, reducing the possibility of sudden changes and compression of the rice husks and ensuring the balanced flow of the rice husks. On the other hand, it restricts the accumulation and blockage of rice husks in the gap space, allowing the rice husks to flow smoothly to the bottom outlet of the feeding hopper 1, that is, the lower part 103, avoiding the problem of uneven feeding.

[0028] In a preferred embodiment, refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 The air blowing section 5 includes an inclined air blowing pipe 51 connected to the surface of the positioning rod 3. A solenoid valve 52 is installed on the surface of the inclined air blowing pipe 51. A solenoid valve 13 is installed on the surface of the positioning rod 3, located below the top port of the inclined air blowing pipe 51. A pair of mounting blocks 53 are fixed inside the inclined air blowing pipe 51. Holes are distributed on the surface of the mounting blocks 53. Guide rods 54 are fixed inside the two mounting blocks 53. Heating wires 55 are wound on the guide rods 54. A protective net 56 is provided at the end of the inclined air blowing pipe 51 located on the surface of the feeding platform 2.

[0029] This technical solution is adopted to dry the damp rice husks adhering to the feeding platform 2, reducing the adhesion and moisture content of the rice husks, making them easier to blow away from the surface of the feeding platform 2. At the same time, after drying, some damp rice husks can also be less likely to stick in the pipe located at the lower part 103 of the feeding hopper 1, further reducing the problem of blockage and uneven discharge. Therefore, based on this phenomenon, a heating wire 55 is installed in the inclined air blowing pipe 51. With the cooperation of the guide rod 54 and the mounting block 53, the heating wire 55 can operate stably in the inclined air blowing pipe 51. In this way, when the hot air blown out of the outlet of the inclined air blowing pipe 51 is blown onto the surface of the feeding platform 2, the rice husks adhering to the feeding platform 2 can be removed, effectively drying the damp rice husks adhering to the feeding platform 2, reducing adhesion and moisture content, making them easier to blow away, and at the same time reducing the risk of blockage during the conveying process, ensuring the smooth conveying of rice husks.

[0030] In addition, the protective net 56 designed at the air outlet of the inclined air pipe 51 is used to prevent rice husks or other debris from entering the inclined air pipe 51, so as to avoid the inclined air pipe 51 being blocked or damaged.

[0031] In a preferred embodiment, refer to Figure 6 and Figure 7 The bottom of the feeding platform 2 is provided with a weight-reducing groove 8. The inner top wall diameter of the weight-reducing groove 8 gradually increases to the bottom port diameter, and the top diameter of the feeding platform 2 gradually increases to the bottom diameter. The connection between the feeding platform 2 and the surface of the positioning rod 3 is a sliding connection. When the connection between the feeding platform 2 and the surface of the positioning rod 3 is a sliding connection, a lifting mechanism 9 is included to support the feeding platform 2. The lifting mechanism 9 includes a connecting cylinder 91 that is laterally connected to the positioning rod 3 and communicates with the pipe cavity 6. The top of the connecting cylinder 91 extends with an annular edge 92 fixed to the positioning rod 3. A spring 93 is fitted on the positioning rod 3 and fixed between the top of the annular edge 92 and the inner top wall of the weight reduction groove 8. A connecting shaft 94 is rotatably arranged between the two ends of the connecting cylinder 91. Multiple impellers 95 are fixed on the connecting shaft 94 and are distributed in a circle and located inside the connecting cylinder 91. A circular rotating plate 96 is fixed at both ends of the connecting shaft 94. A pair of arc-shaped protrusions 97 are fixed on the circular rotating plate 96. A top plate 98 fixed on the inner top wall of the weight reduction groove 8 is attached to the surface of the circular rotating plate 96. An air outlet 10 communicating with the inside of the pipe cavity 6 is provided at the bottom of the positioning rod 3.

[0032] With this technical solution, when the air inlet 7 is connected to an external air pump, sufficient air pressure can be provided by the external air pump to enter the pipe cavity 6. Part of the gas entering the pipe cavity 6 can be blown onto the surface of the feed table 2 through the inclined air pipe 51, while the other part of the gas can be blown towards the connecting cylinder 91. This causes the impeller 95, designed for rotation, to rotate under the action of the airflow. Thus, the connecting shaft 94, through the rotation of the impeller 95, can drive the arc-shaped protrusion 97 on the circular rotating plate 96 to continuously move in a circular motion along the surface of the top plate 98. When the arc-shaped protrusion 97 reaches... When the material feeder 2 touches the surface of the top plate 98, it is pushed upward. When the arc-shaped protrusion 97 does not touch the surface of the top plate 98, the material feeder 2 contacts the circular rotating plate 96 under the reset of the spring 93. In this up-and-down reciprocating process, combined with the air blowing on the surface of the material feeder 2 by the inclined air pipe 51, the rice husks adhering to the material feeder 2 are more easily removed. At the same time, during the up-and-down reciprocating process of the material feeder 2, the rice husks located in the gap space can also be better dispersed into the bottom outlet of the feeding hopper 1 for discharge, thereby realizing the smooth conveying and processing of rice husks.

[0033] In addition, since the bottom of the positioning rod 3 has an air outlet 10 that communicates with the inside of the pipe cavity 6, when the impeller 95 is rotating, it can also introduce the gas entering the pipe cavity 6 into the air outlet 10 and blow it into the lower part 103 of the feeding hopper 1. This can further improve the smoothness of rice husk feeding in the lower part 103 and reduce the problem of rice husk blockage in the lower part 103.

[0034] It should be noted that the bottom structure of the top plate 98 in the above scheme is a semi-circular structure. This allows the bottom of the top plate 98 to rotate more smoothly in conjunction with the circular rotating plate 96 and the arc-shaped protrusion 97, making the feeding platform 2 more stable during the up-and-down shaking process.

[0035] In a preferred embodiment, refer to Figures 1-7 A limiting ring 11 is fixed to the bottom edge of the positioning rod 3. A material unloading component 12 that is linked with the circular rotating plate 96 slides between the top and bottom of the limiting ring 11. The material unloading component 12 includes a material unloading rod 121 that is slidably connected between the top and bottom of the limiting ring 11. One end of the material unloading rod 121 corresponds to the top of the bottom outlet of the feeding hopper 1. The other end of the material unloading rod 121 is fixed with a semi-circular block 122 that fits against the surface of the circular rotating plate 96. A spring 123 is sleeved on the surface of the material unloading rod 121 and fixed between the top of the limiting ring 11 and the bottom of the semi-circular block 122.

[0036] By adopting this technical solution, the material-draining component 12 designed on the annular edge 92, in conjunction with the circular rotating plate 96, ensures that when the circular rotating plate 96 and the arc-shaped protrusion 97 continuously rotate along the corresponding surface between the top plate 98 and the semi-circular block 122, the semi-circular block 122 will be repeatedly pushed by the arc-shaped protrusion 97, driving the material-draining rod 121 into the lower 103 pipe. When the circular rotating plate 96 contacts the corresponding surface between the semi-circular block 122 and the top plate 98, the semi-circular block 122 will return to its initial position under the elastic force of the spring 123. This allows the material-draining rod 121 to further dredge the rice husks in the lower 103 of the feeding hopper 1 during this up-and-down reciprocating process, ensuring that the rice husks can be smoothly transported in the lower 103 and improving the carbonization efficiency.

[0037] In addition, it should be noted that if there are many rice husks on the feeding platform 2, when the air inlet 7 provides sufficient air pressure to enter the pipe cavity 6 through the external air pump, and a part of the gas entering the pipe cavity 6 drives the impeller 95 to drive the circular rotating plate 96 connected by the connecting shaft 94 to rotate between the top plate 98 and the semi-circular block 122, in order to ensure that the gas has enough power to rotate the impeller 95, the solenoid valve 52 on the surface of the inclined air blowing pipe 51 can be closed according to the usage. At this time, the solenoid valve 13 on the positioning rod 3 is in the open state, so that the airflow can have enough power to drive the impeller 95 to rotate, realize the up and down shaking of the feeding platform 2 and the conveying of the rice husks in the lower part 103 by the unloading rod 121, and ensure that the rice husks can be smoothly fed through the feeding hopper 1.

[0038] If there are not many rice husks on the feeding platform 2, the solenoid valve 52 on the inclined air blowing pipe 51 and the solenoid valve 13 on the positioning rod 3 can both be in the open state.

[0039] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
