Description

Technical Field

[0001] This invention relates to the field of feeding technology, and in particular to a device for precise quantitative continuous feeding of negative carbon biomineral raw materials. Background Technology

[0002] Negative carbon biomineral raw materials are a new type of environmentally friendly composite raw material that combines the properties of biological carbon sequestration and emission reduction with the excellent application performance of mineral substrates. They can be widely used in many fields such as pet cleaning products, ecological restoration matrix, and environmentally friendly building material fillers. With the continuous promotion of the dual-carbon development strategy, the process of industrial-scale production is accelerating. Its production and preparation requires the completion of multiple processes such as multi-component raw material compatibility, molding and processing, and post-processing and grading to produce finished raw materials that meet performance standards.

[0003] The conventional quantitative feeding method in existing production directly measures and adds the mixed raw materials as a whole without pre-separating and removing ultrafine dust and fine particulate impurities mixed in the raw materials. This results in deviations in the actual effective amount of finished product particles fed, making it difficult to consistently ensure the proportion accuracy of multi-component raw materials and easily causing batch-to-batch differences in the performance of finished products. At the same time, conventional feeding equipment cannot simultaneously complete the removal of impurities from raw materials and the dynamic correction of metering deviations during the quantitative process, making it difficult to adapt to the large-scale continuous production requirements of high-quality negative carbon biomineral raw materials. Therefore, there is an urgent need for a precise quantitative continuous feeding device for negative carbon biomineral raw materials. Summary of the Invention

[0004] The purpose of this invention is to provide a precise quantitative continuous feeding device for negative carbon biomineral raw materials, which solves the problem in the prior art that the ultrafine dust and fine particulate impurities mixed in the raw materials are not separated and removed in advance, resulting in deviations in the actual effective finished product particle feeding amount and making it difficult to stably ensure the proportion accuracy of multi-component raw materials.

[0005] To achieve the above objectives, the present invention provides a precise quantitative continuous feeding device for negative carbon biomineral raw materials, including a storage bin and a feeding assembly, wherein a processing box is provided on one side of the storage bin; The feeding assembly includes a feeding pipe, a feeding hopper, a dust collection mechanism, a discharge mechanism, a pressure sensor, an impurity collection unit, and a shaking unit. The feeding pipe is connected to the lower part of the storage hopper. The feeding hopper is located below the feeding pipe. The dust collection mechanism, the discharge mechanism, and the impurity collection unit are sequentially arranged on the feeding hopper. The pressure sensor is located at the inner bottom of the feeding hopper, and the shaking unit is located below the feeding hopper.

[0006] The feeding assembly further includes a valve and a sealing mechanism. The valve is located on the feeding pipe, and the sealing mechanism is located inside the feeding hopper.

[0007] The sealing mechanism includes a sealing cylinder and a sealing plate. The feeding bin has a groove and an inlet. The inlet is adapted to the discharge pipe. The sealing cylinder is located inside the groove. The output end of the sealing cylinder is fixedly connected to the sealing plate. The sealing plate is adapted to the groove.

[0008] The dust collection mechanism includes a dust collection pipe and a dust collection pump. The dust collection pipe is installed on the feeding bin, and the dust collection pump is installed inside the feeding bin. The dust collection pump is connected to the dust collection pipe.

[0009] The discharge mechanism includes a discharge plate and an opening and closing motor. The discharge plate is rotatably connected to one side of the feeding bin. The opening and closing motor is located on one side of the feeding bin. The output end of the opening and closing motor passes through the feeding bin and is fixedly connected to the discharge plate.

[0010] The impurity collection unit includes an impurity box and an inclined plate. A filter plate is provided between the impurity box and the feeding bin. The impurity box is detachably connected to one end of the feeding bin. The inclined plate is located on the inner side wall of the feeding bin and on one side of the filter plate.

The output end of the horizontal electric slide rail is fixedly connected to the lifting cylinder. The output end of the lifting cylinder is fixedly connected to the bracket. The feeding hopper is rotatably connected to the inside of the bracket. The tilting motor is located on one side of the bracket. The output end of the tilting motor passes through the bracket and is fixedly connected to the feeding hopper.

[0012] This invention discloses a precise quantitative continuous feeding device for negative carbon biomineral raw materials. During operation, the valve opens, and the raw material in the storage silo falls into the feeding silo through the feeding pipe. A pressure sensor weighs the material in real time, and once the set amount is reached, the valve closes to stop feeding. A sealing mechanism seals the inlet to keep the silo airtight. A shaking unit drives the feeding silo to move laterally and reciprocate, continuously agitating the material to remove dust and impurities. Simultaneously, a dust collection mechanism generates negative pressure airflow, allowing dust and impurities to pass through a filter plate and enter an impurity box for collection, while qualified particles are retained. After quantitative impurity removal, the discharge plate opens, and qualified raw materials are discharged into the processing box. After unloading, all components reset and replenish material, continuously achieving precise quantitative feeding. Therefore, real-time weighing using pressure sensors, combined with valve on / off control, enables high-precision quantitative feeding; the shaking and tumbling combined with a negative pressure dust extraction structure can simultaneously remove ultrafine dust and fine particulate impurities during the metering process, ensuring the feeding accuracy of effective finished particles and stabilizing the proportion of multi-component raw materials; the modular continuous cycle operation can efficiently connect the entire process of storage, metering, impurity removal, and processing, greatly improving feeding efficiency and batch stability, and meeting the needs of large-scale, high-quality production of negative carbon biomineral raw materials.

Detailed Implementation

[0019] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0020] Please see Figures 1 to 4This invention provides a precise quantitative continuous feeding device for negative carbon biomineral raw materials, including a storage bin 1 and a feeding assembly. A processing box 2 is provided on one side of the storage bin 1. The feeding assembly includes a feeding pipe 3, a feeding bin 4, a dust collection mechanism, a discharge mechanism, a pressure sensor 5, an impurity collection unit, and a shaking unit. The feeding pipe 3 is connected to the lower part of the storage bin 1. The feeding bin 4 is located below the feeding pipe 3. The dust collection mechanism, the discharge mechanism, and the impurity collection unit are sequentially arranged on the feeding bin 4. The pressure sensor 5 is located at the inner bottom of the feeding bin 4, and the shaking unit is located below the feeding bin 4.

[0021] In this embodiment, the storage silo 1 is a large-capacity storage silo for raw materials, used to temporarily store carbon-negative biomineral raw materials to be added. The processing box 2 is a receiving cavity for subsequent processing steps of the raw materials, receiving quantitatively added raw materials for further processing. The discharge pipe 3 is a raw material conveying channel, connecting the storage silo and the feeding silo to realize gravity discharge of materials. The feeding silo 4 is the core cavity for quantitative metering and impurity removal, receiving the falling raw materials and completing metering and impurity removal. The pressure sensor 5 is set at the bottom of the feeding silo, which can collect the weight data of the materials in the silo in real time, realizing accurate quantitative weighing and ensuring the accuracy of the feeding amount. The dust collection mechanism can generate negative pressure airflow in the sealed silo to remove ultrafine dust and fine particulate impurities mixed in the raw materials. The discharge mechanism is a discharge control component after quantitative completion, which can be opened to discharge the metered qualified raw materials to the processing box. The impurity collection unit is used to collect the separated dust and impurities for centralized cleaning. The shaking unit drives the feeding hopper to reciprocate, continuously agitating the material and promoting the separation of dust and impurities from qualified particles. It also assists in uniform material feeding, preventing accumulation and jamming. Through a structure combining weighing and quantitative feeding with simultaneous impurity removal, impurities can be removed simultaneously during quantitative feeding, ensuring the accuracy of effective finished particle feeding and achieving precise and continuous feeding.

[0022] Furthermore, the feeding assembly also includes a valve 6 and a sealing mechanism. The valve 6 is disposed on the feeding pipe 3, and the sealing mechanism is disposed inside the feeding hopper 4.

[0023] In this embodiment, valve 6 is a control valve for the feeding pipeline, which controls the start and stop of feeding from the storage silo to the feeding silo, and achieves quantitative feeding in conjunction with the weight signal from the pressure sensor. The sealing mechanism is located at the inlet of the feeding silo, which can close the inlet during metering and impurity removal operations, making the feeding silo a sealed space. This ensures the effectiveness of negative pressure dust collection, prevents dust from overflowing from the inlet, and prevents external airflow from interfering with the pressure weighing accuracy, thus ensuring quantitative accuracy.

[0024] Furthermore, the sealing mechanism includes a sealing cylinder 7 and a sealing plate 8. The feeding bin 4 has a groove 9 and an inlet 10. The inlet 10 is adapted to the discharge pipe 3. The sealing cylinder 7 is disposed inside the groove 9. The output end of the sealing cylinder 7 is fixedly connected to the sealing plate 8. The sealing plate 8 is adapted to the groove 9.

[0025] In this embodiment, the groove 9 is a receiving and mounting groove for the sealing plate, used to house the sealing plate and prevent it from protruding and obstructing material from falling. The feed inlet 10 is the feed opening at the top of the feeding hopper, aligned and connected to the discharge pipe. The sealing cylinder 7 is the power component for the sealing action, which can drive the sealing plate to extend and slide along the groove, covering the feed inlet to achieve a seal, and retracting it opens the feed inlet to resume feeding. The sealing plate is a flat sealing structure, adapted to the size of the feed inlet, with good sealing performance and smooth and reliable operation. The cylinder-driven translational sealing structure can quickly complete the opening and closing of the feed inlet, with a fast response speed, adapting to the rhythm of continuous feeding.

[0026] Furthermore, the dust collection mechanism includes a dust collection pipe 11 and a dust collection pump 12. The dust collection pipe 11 is disposed on the feeding bin 4, and the dust collection pump 12 is disposed inside the feeding bin 4. The dust collection pump 12 is connected to the dust collection pipe 11.

[0027] In this embodiment, the dust pump 12 is a negative pressure air source, which can generate negative pressure airflow in the sealed feeding hopper to lift and remove ultrafine dust and fine particulate impurities mixed in the material; the dust suction pipe 11 is a conveying channel for airflow and dust, which can guide the extracted dust to the impurity collection unit. By using negative pressure dust suction, light dust impurities in the material can be efficiently removed without damaging qualified particles, and the impurity removal process is gentle.

[0028] Furthermore, the discharge mechanism includes a discharge plate 13 and an opening and closing motor 14. The discharge plate 13 is rotatably connected to one side of the feeding bin 4, and the opening and closing motor 14 is disposed on one side of the feeding bin 4. The output end of the opening and closing motor 14 passes through the feeding bin 4 and is fixedly connected to the discharge plate 13.

[0029] In this embodiment, the discharge plate 13 is the discharge door plate on the side of the feeding hopper. When closed, it can seal the discharge port to ensure the hopper is airtight. When opened, it can discharge the metered and impurity-removed raw materials. The opening and closing motor 14 is the rotation drive component of the discharge plate, which can precisely drive the discharge plate to rotate and open and close. The discharge opening degree is controllable, and the unloading speed can be adjusted according to needs to ensure continuous and stable feeding.

[0030] Furthermore, the impurity collection unit includes an impurity box 15 and an inclined plate 16. A filter plate 17 is provided between the impurity box 15 and the feeding bin 4. The impurity box 15 is detachably connected to one end of the feeding bin 4. The inclined plate 16 is provided on the inner side wall of the feeding bin 4 and is located on one side of the filter plate 17.

[0031] In this embodiment, the filter plate 17 has a porous sieving structure with mesh sizes smaller than the qualified raw material particle size, allowing dust and fine impurities to pass through while retaining qualified raw material particles, thus achieving the separation of materials and impurities. The inclined plate 16 is arranged at an angle inside the filter plate, guiding airflow and dust towards the filter plate, improving the impurity passage efficiency, and simultaneously preventing materials from directly impacting the filter plate, protecting the screen. The impurity box 15 is an impurity collection cavity, detachably connected to the side of the feeding hopper, used to collect the filtered dust and impurities. It can be disassembled for cleaning when full, making maintenance convenient.

[0032] Furthermore, the shaking unit includes a horizontal electric slide rail 18, a lifting cylinder 19, a bracket 20, and a tilting motor 21. The horizontal electric slide rail 18 is located below the feeding bin 4. The output end of the horizontal electric slide rail 18 is fixedly connected to the lifting cylinder 19. The output end of the lifting cylinder 19 is fixedly connected to the bracket 20. The feeding bin 4 is rotatably connected to the inside of the bracket 20. The tilting motor 21 is located on one side of the bracket 20. The output end of the tilting motor 21 passes through the bracket 20 and is fixedly connected to the feeding bin 4.

[0033] In this embodiment, the transverse electric slide rail 18 is a transverse driving component that can drive the feeding bin to move back and forth laterally, generating horizontal swaying that causes the material to tumble left and right, promoting impurity separation. The lifting cylinder 19 is a vertical driving component that can drive the support and feeding bin to lift and lower, adjusting the working height to adapt to different docking conditions. The support 20 is the load-bearing tilting frame of the feeding bin, providing installation support for the tilting motor and bearing the weight of the feeding bin. The tilting motor 21 can drive the feeding bin to tumble back and forth around its axis, generating vertical swaying and bouncing that causes the material to tumble up and down, further enhancing the impurity separation effect. It can also assist in tilting during unloading, accelerating the discharge speed. Through the combined transverse movement and tilting swaying structure, the material can be fully tumbled, promoting the complete detachment of dust and impurities and their movement towards the filter plate side, improving the impurity removal efficiency and thoroughness, while also assisting in unloading to avoid clogging.

[0034] When using the precise quantitative continuous feeding device for negative carbon biomineral raw materials according to this embodiment, in the initial state, the valve 6 is closed, the discharge plate 13 is closed, the sealing plate 8 is retracted into the groove 9, and the inlet 10 is open. When the operation starts, the valve 6 opens, and the negative carbon biomineral raw materials in the storage bin 1 fall into the feeding bin 4 below through the discharge pipe 3 and the inlet 10; the pressure sensor 5 collects the weight of the material in the bin in real time, and when the weight reaches the set quantitative value, the valve 6 closes and the feeding stops. Subsequently, the sealing cylinder 7 drives the sealing plate 8 to extend from the groove 9, covering the feed inlet 10, so that the feeding bin 4 forms a sealed cavity; the shaking unit is activated, the horizontal electric slide rail 18 drives the feeding bin 4 to move horizontally back and forth, and the flipping motor 21 synchronously drives the feeding bin 4 to flip back and forth at a small angle, causing the material to continuously turn over, so that the ultrafine dust and fine impurities mixed between the particles are fully lifted and removed; at the same time, the dust pump 12 is activated, generating negative pressure airflow in the bin, and the lifted dust and impurities pass through the filter plate 17 with the airflow, and are guided by the inclined plate 16 into the impurity box 15 on the side for collection. Qualified raw material particles are intercepted by the filter plate, completing the synchronous impurity removal in the quantitative process. After the quantitative impurity removal is completed, the dust pump and shaking unit stop, and the opening and closing motor 14 drives the discharge plate 13 to rotate and open. The metered qualified raw materials are discharged from the discharge port and enter the processing box 2 on the side to complete the feeding. During the unloading process, the tilting motor can tilt back and forth slightly to assist the feeding and avoid material residue sticking to the wall. After the unloading is completed, the discharge plate closes, the sealing plate retracts and the inlet is opened, the valve is opened again to replenish the material, and the next round of quantitative impurity removal feeding cycle begins, thereby realizing the precise quantitative continuous feeding of negative carbon biomineral raw materials. After the dust and impurities in the impurity box accumulate to a certain amount, the impurity box can be disassembled for centralized cleaning, making maintenance convenient.
