Technical Field
[0001] The utility model relates to the technical field of inoculant production equipment, and specifically, to a feeding hopper for inoculant production and processing. Background Technique
[0002] In modern industrial production, inoculants play an important role in improving the properties of metal materials. The production and processing process of inoculants requires precise control of the addition ratio and sequence of various raw materials to ensure the stable and reliable quality of the final product.
[0003] As one of the key equipment in inoculant production and processing, the performance of the feeding hopper directly affects the production efficiency and product quality. In the past, traditional feeding hoppers often had some problems and deficiencies.
[0004] For example, the early design of the feeding hopper was simple. Due to the inconsistent particle sizes of the raw materials, during the feeding process, larger-sized particles were prone to clogging the feeding port, while smaller-sized particles might fall prematurely, affecting the smoothness of feeding, resulting in a disproportion in the feeding ratio, and affecting the quality and performance of the final inoculant product.
[0005] Due to poor sealing performance, combined with the impact of the falling material and air flow, dust might fly during the feeding process, causing both waste of raw materials and adverse effects on the working environment and the health of operators.
[0006] In addition, traditional feeding hoppers performed poorly in controlling the feeding speed and accuracy, and were difficult to meet the requirements of high-precision production processes. This might lead to deviations in the addition ratio of raw materials, ultimately affecting the chemical composition and performance indicators of the inoculant.
[0007] In view of the above problems, the prior art has not solved them well, bringing trouble to the normal progress of work in this field. Therefore, there is an urgent need for a feeding hopper for inoculant production and processing to solve the above problems. Content of the Utility Model
[0008] The utility model provides a feeding hopper for inoculant production and processing, which solves the problem in the related art that the particle sizes of raw materials are inconsistent and larger-sized particles are prone to clogging the feeding port.
[0009] The technical solution of the present utility model is as follows: A feeding hopper for the production and processing of inoculants, comprising a hopper main body, a sieve plate and a vibration motor. The inner wall of the hopper main body has a chute. The sieve plate is slidably arranged relative to the hopper main body and is located in the chute. The sieve plate has sieve holes. There is an included angle between the sieve plate and the horizontal plane. The vibration motor is arranged on the sieve plate and is used to drive the sieve plate to reciprocate in the chute. The side wall of the hopper main body has a recovery port, and the recovery port is located at the bottom end of the sieve plate for recovering materials with a particle size larger than the sieve holes.
[0010] Optionally, the sieve plate includes an outer frame and split plates. The outer frame is slidably arranged in the chute. The split plates are detachably arranged on the outer frame. There are multiple split plates, and the sieve holes are located on the split plates. The vibration motor is arranged on the outer frame.
[0011] Optionally, it further includes a rotating shaft and blades. There is a throttling chamber in the hopper main body. The throttling chamber is circular. The rotating shaft is rotatably arranged in the throttling chamber. The blades are arranged on the rotating shaft. There are multiple blades and they are evenly distributed along the circumferential direction of the rotating shaft. The blades abut against the inner wall of the throttling chamber.
[0012] Optionally, it further includes a diversion disk. The diversion disk is rotatably arranged in the hopper main body. The diversion disk has multiple diversion vanes. The diversion disk is located below the throttling chamber. The diversion disk is conical, and the small-diameter end of the diversion disk faces upward.
[0013] Optionally, it further includes a support plate, a transmission chain and a driving motor. The support plate is arranged on the inner wall of the hopper main body. The diversion disk is rotatably arranged on the support plate. The driving motor is arranged on the outer wall of the hopper main body. The driving motor is drivingly connected to the diversion disk through the transmission chain for driving the diversion disk to rotate. The transmission chain is located below the support plate. A through hole is opened on the side wall of the hopper main body for the transmission chain to pass through.
[0014] Optionally, it further includes a wear-resistant plate. The wear-resistant plate is detachably arranged on the inner wall of the hopper main body.
[0015] Optionally, the top of the hopper main body has a feed inlet, and the feed inlet is located above the top end of the sieve plate.
[0016] Optionally, the top of the hopper main body has a dust removal port. The dust removal port is located above the sieve plate and is used to communicate with a negative pressure unit.
[0017] The working principle and beneficial effects of the present utility model are:
[0018] During the production and processing of inoculants, when raw materials need to be added to the feeding hopper, the materials are poured into the hopper body. The sieve plate has an angle with the horizontal plane and is inclined, which can help the materials roll down by their own weight. And driven by the vibration motor, the sieve plate slides back and forth in the chute, generating vibration. Materials with smaller particle sizes can smoothly pass through the sieve holes on the sieve plate and flow down along the inner wall of the hopper body into the subsequent production and processing links. While materials with larger particle sizes are blocked by the sieve holes on the sieve plate and gradually move towards the bottom end of the sieve plate under the vibration of the sieve plate. When these large-particle-size materials move to the recovery port, they are recovered through the recovery port for further processing, such as crushing or re-screening, to ensure compliance with production requirements.
[0019] This solution effectively solves the problem of inconsistent particle sizes of raw materials and avoids the blockage of the feeding port by large-particle-size particles. Through the screening effect of the sieve holes on the sieve plate, the large-particle-size materials are separated, ensuring the smoothness of the feeding process and improving production efficiency. It can accurately control the particle size of the materials entering the subsequent production links, making the feeding ratio more accurate, thus ensuring the stable and reliable quality and performance of the inoculant product. Since the large-particle-size materials can be separated and recovered in a timely manner, the accumulation and blockage of materials in the feeding hopper are reduced, and the frequency and cost of equipment maintenance are lowered. The design of driving the sieve plate by a vibration motor requires no complex operation and additional power source, with a simple structure, easy to implement and maintain.

[0030] In addition, in the description of this application, the terms "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.
[0031] Refer to Figures 1 to 5, which is the first embodiment of the present utility model, proposes a feeding hopper for the production and processing of inoculants, including a hopper main body 1, a sieve plate 2 and a vibration motor 3. The inner wall of the hopper main body 1 has a chute 4. The sieve plate 2 is slidably arranged relative to the hopper main body 1 and is located in the chute 4. The sieve plate 2 has sieve holes 5. There is an angle between the sieve plate 2 and the horizontal plane. The vibration motor 3 is arranged on the sieve plate 2 and is used to drive the sieve plate 2 to reciprocate in the chute 4. A recovery port 6 is provided on the side wall of the hopper main body 1, and the recovery port 6 is located at the bottom end of the sieve plate 2 for recovering materials with a particle size larger than the sieve holes 5.
[0032] In this embodiment, during the production and processing of inoculants, when raw materials need to be added to the feeding hopper, the materials are poured into the hopper main body 1. There is an angle between the sieve plate 2 and the horizontal plane, and it is in an inclined state, which can help the materials roll down by their own weight. And under the drive of the vibration motor 3, the sieve plate 2 reciprocates in the chute 4 to generate vibration. Materials with a smaller particle size can smoothly pass through the sieve holes 5 on the sieve plate 2 and flow down along the inner wall of the hopper main body 1 into the subsequent production and processing links. While materials with a larger particle size are blocked by the sieve holes 5 on the sieve plate 2 and gradually move towards the bottom end of the sieve plate 2 under the vibration of the sieve plate 2. When these large-particle-size materials move to the recovery port 6, they are recovered through the recovery port 6 and further processed, such as crushing or re-screening, to ensure compliance with production requirements.
[0033] This solution effectively solves the problem of inconsistent particle sizes of raw materials and avoids the blockage of the feeding port by large-particle-size particles. Through the screening effect of the sieve holes 5 on the sieve plate 2, the large-particle-size materials are separated, ensuring the smoothness of the feeding process and improving production efficiency. It can accurately control the particle size of the materials entering the subsequent production links, making the feeding ratio more accurate, thereby ensuring the stable and reliable quality and performance of the inoculant product. Since the large-particle-size materials can be separated and recovered in a timely manner, the accumulation and blockage of materials in the feeding hopper are reduced, and the frequency and cost of equipment maintenance are lowered. The design of the vibration motor 3 driving the sieve plate 2 requires no complex operation and additional power source, and has a simple structure, which is easy to implement and maintain. 1
[0034] The sieve plate 2 includes an outer frame 7 and split plates 8. The outer frame 7 is slidably arranged in the chute 4. The split plates 8 are detachably arranged on the outer frame 7. There are multiple split plates 8, and the sieve holes 5 are located on the split plates 8. The vibration motor 3 is arranged on the outer frame 7.
[0035] In this embodiment, the outer frame 7 is slidably arranged in the chute 4 of the hopper main body 1. Multiple split plates 8 are detachably installed on the outer frame 7, and the sieve holes 5 are distributed on these split plates 8. The outer frame 7 and the multiple split plates 8 together form the sieve plate 2. When the vibration motor 3 works, it drives the outer frame 7 to reciprocate in the chute 4 to generate vibration.
[0036] During long-term use, if a split plate 8 is damaged, it can be directly removed from the outer frame 7 for individual replacement without replacing the entire sieve plate 2, making the operation simple and fast. Moreover, if it is necessary to change the particle size of the screened material, only the split plate 8 with different-sized sieve holes 5 needs to be replaced, greatly reducing the maintenance cost and time. There is no need to replace the entire sieve plate 2 due to local damage, reducing resource waste. Secondly, by replacing the split plate 8 with different-sized sieve holes 5, it can flexibly adapt to different production requirements, meet the screening requirements for materials with different particle sizes, and improve the versatility and applicability of the hopper. This design method makes the maintenance and adjustment of the hopper more convenient and efficient, helps to ensure the continuity and stability of the inoculant production and processing, and improves the overall production efficiency and product quality.
[0037] It further includes a rotating shaft 9 and blades 10. A throttling chamber 11 is provided in the hopper main body 1. The throttling chamber 11 is circular. The rotating shaft 9 is rotatably arranged in the throttling chamber 11. The blades 10 are arranged on the rotating shaft 9. There are multiple blades 10 and they are evenly distributed along the circumferential direction of the rotating shaft 9. The blades 10 abut against the inner wall of the throttling chamber 11.
[0038] In this embodiment, during the production and processing of the inoculant, the material enters the throttling chamber 11 after being screened by the sieve plate 2. The rotating shaft 9 in the throttling chamber 11 rotates driven by a driving device, and the multiple blades 10 mounted on the rotating shaft 9 rotate accordingly. Since the blades 10 abut against the inner wall of the throttling chamber 11, they divide the throttling chamber 11 into multiple discharge chambers. When the blades 10 rotate, the material is gradually brought into each discharge chamber and is stably pushed out of the throttling chamber 11 quantitatively along with the rotation of the blades 10, thereby realizing uniform discharging. In this way, it can be ensured that the material enters the subsequent production links at a stable speed and in a uniform quantity.
[0039] First of all, the throttling chamber 11 is divided by multiple blades 10, and quantitative and stable discharging is realized by relying on the rotation of the blades 10, effectively ensuring the uniformity of feeding. It avoids the problems of unstable and uneven discharging speed of the material during the feeding process, thereby improving the quality stability of the product. Secondly, this quantitative and stable discharging method helps to accurately control the material addition amount in the production process and meet the requirements of high-precision production processes. It reduces the product quality fluctuations caused by uneven feeding and improves the consistency and reliability of the product. Moreover, it can better match the entire production process, optimize the production rhythm, and improve the production efficiency. It makes the entire inoculant production and processing process more controllable, stable and efficient.
[0040] It further includes a diversion plate 12 which is rotatably arranged in the hopper main body 1. The diversion plate 12 is provided with a plurality of diversion vanes 13. The diversion plate 12 is located below the throttling chamber 11. The diversion plate 12 is conical, and the small-diameter end of the diversion plate 12 faces upward.
[0041] In this embodiment, during the production and processing of the inoculant, the material that is quantitatively and stably discharged through the throttling chamber 11 falls onto the lower diversion plate 12. The diversion plate 12 continuously rotates under the action of the driving device, and the plurality of diversion vanes 13 thereon rotate accordingly. When the material contacts the rotating diversion plate 12, under the action of centrifugal force, it is thrown out in all directions by means of the diversion vanes 13. Since the diversion plate 12 is conical and its small-diameter end faces upward, the material first contacts the small-diameter end during the falling process and is more likely to be dispersed in all directions. Thus, the material can be more evenly distributed to the subsequent production links, avoiding the uneven distribution caused by the material being added in piles in the prior art.
[0042] First of all, through the rotation of the diversion plate 12 and the action of the diversion vanes 13, the material falling from the throttling chamber 11 can be evenly thrown out in all directions, significantly improving the uniformity of feeding, effectively avoiding the unevenness problem caused by the material being added in piles, and ensuring the stability of the product quality. Secondly, the conical design of the diversion plate 12 helps to better disperse the material, improving the effect of material distribution and further optimizing the feeding process. Moreover, this uniform feeding method makes the production process more controllable and stable, reducing production anomalies and product quality defects caused by uneven feeding, and improving production efficiency and product qualification rate.
[0043] It further includes a support plate 14, a transmission chain 15 and a driving motor 16. The support plate 14 is arranged on the inner wall of the hopper main body 1. The diversion plate 12 is rotatably arranged on the support plate 14. The driving motor 16 is arranged on the outer wall of the hopper main body 1. The driving motor 16 is drivingly connected to the diversion plate 12 by means of the transmission chain 15 for driving the diversion plate 12 to rotate. The transmission chain 15 is located below the support plate 14. A through hole 17 is opened on the side wall of the hopper main body 1 for the transmission chain 15 to pass through.
[0044] In this embodiment, during the production and processing of the inoculant, the support plate 14 is fixedly installed on the inner wall of the hopper body 1, and the shunt plate 12 is rotatably installed on the support plate 14 through a transmission shaft at its bottom. After the drive motor 16 on the outer wall of the hopper body 1 is started, it is drivingly connected to the sprocket on the transmission shaft of the shunt plate 12 through the transmission chain 15. When the drive motor 16 works, power is transmitted to the sprocket through the transmission chain 15, thereby driving the shunt plate 12 to rotate. The transmission chain 15 passes through the through hole 17 on the side wall of the hopper body 1 and is connected to the sprocket. And since the transmission chain 15 is located below the support plate 14, the support plate 14 can effectively protect the transmission chain 15 and prevent materials from interfering with and damaging the transmission chain 15.
[0045] First of all, the support plate 14 provides a stable installation support for the shunt plate 12, ensuring that the shunt plate 12 can rotate smoothly, thus guaranteeing the effect and stability of material dispersion. Secondly, the drive motor 16 is drivingly connected to the shunt plate 12 through the transmission chain 15. This transmission method is simple and reliable, and can effectively transmit power to the shunt plate 12, enabling it to rotate according to the design requirements. Moreover, the through hole 17 on the side wall of the hopper body 1 provides a suitable channel for the transmission chain 15, making the layout of the transmission structure more reasonable. Finally, the support plate 14 protects the transmission chain 15 located below it, extends the service life of the transmission chain 15, reduces the incidence of equipment failures, reduces the maintenance cost, and ensures the continuity and stability of production.
[0046] It also includes a wear-resistant plate 18, and the wear-resistant plate 18 is detachably arranged on the inner wall of the hopper body 1.
[0047] In this embodiment, during the production and processing of the inoculant, the wear-resistant plate 18 is detachably installed on the inner wall of the hopper body 1. When the material flows and collides in the hopper body 1, it mainly contacts the wear-resistant plate 18. As the use time prolongs, if the wear-resistant plate 18 is worn, it can be detached from the inner wall of the hopper body 1 and a new wear-resistant plate 18 can be replaced.
[0048] First of all, the setting of the wear-resistant plate 18 can effectively reduce the wear of the inner wall of the hopper body 1 by the material and extend the service life of the hopper body 1. Secondly, the detachable design makes the replacement of the wear-resistant plate 18 very convenient, reducing the maintenance cost and the difficulty of repair.
[0049] The hopper body 1 has a feed inlet 19 at the top, and the feed inlet 19 is located above the top end of the sieve plate 2.
[0050] In this embodiment, during the feeding process of inoculant production, the material is poured into the hopper main body 1 from the feed inlet 19 at the top. Since the feed inlet 19 is located above the top end of the sieve plate 2, the material first falls on the higher end of the sieve plate 2. As the sieve plate 2 slides back and forth under the action of the vibration motor 3, the material gradually moves towards the lower end on the sieve plate 2. During this process, there is sufficient time and distance for materials of different particle sizes to be fully separated. The materials with smaller particle sizes can pass through the sieve holes 5 in time and fall down, while the materials with larger particle sizes are gradually pushed to the lower end of the sieve plate 2 and finally recycled through the recovery port 6.
[0051] First of all, the design that the feed inlet 19 is located above the top end of the sieve plate 2 extends the screening time of the material on the sieve plate 2, making the screening more sufficient and accurate, and improving the screening effect. Secondly, more sufficient screening helps to ensure that the particle sizes of the materials entering the subsequent production links are more uniform, thereby enhancing the stability of product quality. Moreover, it can reduce the problems of material waste and production efficiency reduction caused by insufficient screening, and improve the economy and efficiency of production.
[0052] The top of the hopper main body 1 is provided with a dust removal port 20, the dust removal port 20 is located above the sieve plate 2, and the dust removal port 20 is used to communicate with the negative pressure unit.
[0053] In this embodiment, during the production and processing of the inoculant, when the material is poured from the feed inlet 19 onto the sieve plate 2 in the hopper main body 1, the vibration motor 3 drives the sieve plate 2 to vibrate for screening operation. During this process, dust will be generated. At this time, the negative pressure unit connected to the dust removal port 20 starts to work. Since the dust removal port 20 is located above the sieve plate 2, it can effectively suck away the dust generated during screening. The dust is sucked into the negative pressure unit through the dust removal port 20 under the action of negative pressure for treatment, thereby reducing the dust content in the hopper and keeping the working environment clean.
[0054] First of all, the cooperation between the dust removal port 20 and the negative pressure unit can timely and effectively remove the dust generated during screening, greatly improving the working environment and reducing the harm of dust to the health of operators. Secondly, it avoids the accumulation of dust in the hopper, reduces the impact of dust flying on the material quality, and ensures the quality stability of the inoculant product. Moreover, it helps to maintain the normal operation of the equipment, reduces the wear and failure risk of the equipment caused by dust, and extends the service life of the equipment. At the same time, it meets the environmental protection requirements and reduces the pollution of dust to the environment.
[0055] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and all of them should be covered by the scope of the claims of the present invention.
