Description

Technical Field

[0001] The present invention relates to the technical field of grinding systems, and specifically to an adjusting structure for adjusting a grinding system flow rate that is too fast to do work, and aims to achieve effective control of material flow rate, optimize material trajectory, and improve grinding efficiency and uniformity through specially designed upper buffer channels, lower buffer channels and internal components thereof. Background Art

[0002] In the grinding system, the control of material flow rate is one of the key factors to ensure grinding efficiency and product quality. However, traditional grinding systems often face the problem of ineffective work due to too fast material flow rate. When the material enters the grinding equipment at too high a speed, the grinding roller or grinding disc may not be able to fully grind and crush the material, thus affecting the grinding efficiency and the uniformity of the product particle size. In addition, too fast a flow rate will also increase the impact and wear of the material on the internal components of the grinding equipment, shortening the service life of the equipment and increasing maintenance costs.

[0003] In order to solve this problem, some simple flow rate control devices, such as baffles, throttle valves, etc., are often used in the prior art. However, these devices can only roughly adjust the flow rate and cannot accurately control the flow rate and flow direction of the material. At the same time, these devices are prone to wear and blockage during long-term use, and require frequent maintenance and replacement, which increases the operating cost and maintenance difficulty of the equipment.

[0004] In addition, when processing materials of different types and properties, traditional grinding systems often have difficulty adapting to changes in materials due to the lack of an effective flow rate adjustment mechanism. For example, for materials with poor fluidity or large particles, traditional flow rate control devices may not be able to provide sufficient deceleration and flow direction adjustment, resulting in uneven distribution of materials during the grinding process, further affecting grinding efficiency and product quality.

[0005] Therefore, there is an urgent need for an adjustment structure that can accurately adjust the flow rate of the grinding system and optimize the material distribution to improve the grinding efficiency and product quality and extend the service life of the equipment. Summary of the invention

[0006] The present invention provides a regulating structure for adjusting the flow rate of a grinding system that is too fast to do work. The structure aims to achieve effective control of material flow rate, optimize material trajectory, and improve grinding efficiency and uniformity through specially designed upper buffer channels, lower buffer channels and internal components thereof.

[0007] The above technical purpose of the present invention is achieved through the following technical solution: a regulating structure for adjusting the flow rate of a grinding system that is too fast to do work, comprising: An upper buffer channel, wherein an upper rotating rod is rotatably arranged in the upper buffer channel, and a plurality of groups of material blocking leaves are arranged on the outer surface of the upper rotating rod along its length direction, and each group of material blocking leaves is arranged in a ring array; A lower buffer channel, wherein a lower rotating rod is elastically resettable and rotatable in the lower buffer channel, and a plurality of arc pieces are arranged on the outer surface of the lower rotating rod along its length direction, and the arc pieces are C-shaped, and when the lower rotating rod is in an elastic natural state without external force, the inner concave surface of the arc piece faces upward; The upper buffer channel and the lower buffer channel are stacked and arranged at the feeding inlet of the grinding system, the lower buffer channel is arranged below the upper buffer channel, and the two are internally connected.

[0008] In some embodiments, a feed channel is also included. The feed channel is in a square tube shape and is connected to the upper buffer channel. The lower outlet of the feed channel is connected to the inlet of the upper buffer channel, and its cross-sectional area gradually shrinks to match the inlet of the upper buffer channel.

[0009] In some embodiments, the internal path of the feed channel is in a zigzag shape, the path away from the upper buffer channel is inclined, and the path close to the upper buffer channel is vertical.

[0010] In some embodiments, one side of the feed channel is hinged to a corresponding side of the upper buffer channel, so that the feed channel can rotate relative to the upper buffer channel.

[0011] In some embodiments, the upper rotating rod is externally connected to a motor that operates in forward and reverse pulse mode.

[0012] In some embodiments, a plurality of upper rotating rods are arranged side by side, and the material blocking blades on adjacent upper rotating rods are staggered.

[0013] In some embodiments, only one upper rotating rod is connected to the power output end of the motor, and the other upper rotating rods are connected via gear transmission.

[0014] Compared with the prior art, the present invention has the following beneficial effects: The regulating structure of the present invention effectively slows down the flow rate of the material and optimizes the trajectory of the material through the combined action of the upper buffer channel and the lower buffer channel, as well as the unique design of the C-shaped arc piece. The upper rotating rod and its material retaining blade can generate resistance, evenly disperse the impact force of the material, and avoid local wear; the lower rotating rod and its C-shaped arc piece further consume the kinetic energy of the material, guide the material to move in a parabolic shape, and make the material more evenly distributed in the working area of ​​the grinding equipment. This design not only improves the grinding efficiency and uniformity, but also reduces the impact and wear of the material on the internal components of the equipment, extends the service life of the equipment, and reduces maintenance costs. In addition, the design of the feed channel and the driving method of the upper rotating rod further optimize the flow rate control and distribution of the material, so that the regulating structure can adapt to materials of different types and properties, and improve the stability and reliability of the entire grinding system.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] like Figure 1-4 As shown, this embodiment provides a regulating structure for adjusting the flow rate of the grinding system to be too fast to do work, which is characterized by comprising: An upper buffer channel 200 is provided with an upper rotating rod 1 which is rotatably arranged in the upper buffer channel 200. A plurality of groups of material blocking leaves 2 are arranged on the outer surface of the upper rotating rod 1 along its length direction. Each group of material blocking leaves 2 is arranged in a circular array. The upper rotating rod 1 in the upper buffer channel 200 and the material blocking leaves 2 on its surface can generate resistance when the material passes through, thereby slowing down the falling speed of the material.

[0022] The lower buffer channel 300 has a lower rotating rod 4 which is elastically resettable and rotatable in the lower buffer channel 300. The outer surface of the lower rotating rod 4 is provided with multiple arc pieces 5 along its length direction. The arc pieces 5 are C-shaped. When the lower rotating rod 4 is in an elastic natural state without external force, the inner concave surface of the arc piece 5 faces upward. The lower rotating rod 4 in the lower buffer channel 300 and the C-shaped arc piece 5 on its surface can rotate elastically under the impact of the material, further consuming the kinetic energy of the material, thereby reducing the flow rate. The C-shaped design of the arc piece 5 can not only effectively slow down the flow rate of the material, but also cleverly guide the material to move in a parabolic shape. The C-shaped arc piece 5 design makes the material receive an upward component force when it contacts it, so that the material is guided to a parabolic motion trajectory. This trajectory not only helps to further slow down the falling speed of the material, but also makes the material more evenly distributed in the working area of ​​the grinding equipment, thereby improving the uniformity and efficiency of the grinding.

[0023] The upper buffer channel 200 and the lower buffer channel 300 are stacked and arranged at the feeding inlet of the grinding system. The lower buffer channel 300 is arranged below the upper buffer channel 200, and the two are internally connected.

[0024] When the material enters the feeding inlet of the grinding system at a relatively fast speed, it first enters the upper buffer channel 200. In the upper buffer channel 200, the rotating upper rotating rod 1 and the material blocking blades 2 on its surface generate resistance to the material, so that the speed of the material slows down when passing through. The material blocking blades 2 are arranged in a circular array, which can evenly disperse the impact force of the material and avoid local wear.

[0025] Then, the material enters the lower buffer channel 300. In the lower buffer channel 300, the elastically resetting and rotating lower rotating rod 4 and the C-shaped arc piece 5 on its surface further decelerate the material. When the material impacts the lower rotating rod 4, the inner concave surface of the arc piece 5 is designed to face upward, so that the material can more easily push the arc piece 5 to rotate, thereby consuming the kinetic energy of the material. At the same time, the lower rotating rod 4 can quickly return to its original position after being impacted, ready for the next impact.

[0026] Through the deceleration effect of the adjustment structure, the material can enter the grinding equipment at a more suitable speed, so that the grinding roller or grinding disc can fully grind and crush the material, thereby improving the grinding efficiency and obtaining a product with a more uniform particle size. After reducing the flow rate, the impact and wear of the material on the internal components of the grinding equipment are also reduced accordingly, extending the service life of the equipment and reducing maintenance costs. Moreover, since the flow rate is effectively controlled, the energy consumption required for the grinding equipment to maintain normal operation is also reduced accordingly, which helps to save energy and reduce production costs. In addition, the use of the adjustment structure reduces the pressure fluctuation inside the grinding system, improves the overall stability of the system, and reduces the risk of safety accidents.

[0027] In summary, the present invention, through the combined action of the upper buffer channel 200 and the lower buffer channel 300, and the unique design of the C-shaped arc plate 5, not only effectively slows down the flow rate of the material, but also optimizes the trajectory of the material, improves the grinding efficiency and uniformity, and provides a strong guarantee for the stable operation and efficient production of the grinding system.

[0028] In some embodiments, Figure 1-2As shown, it also includes a feed channel 100, which is in the shape of a square tube and connected to the upper buffer channel 200. The lower outlet of the feed channel 100 is connected to the entrance of the upper buffer channel 200, and its cross-sectional area gradually shrinks to match the entrance of the upper buffer channel 200, so as to ensure that the material can enter the upper buffer channel 200 smoothly and concentratedly. The inner wall of the feed channel 100 is designed to be a smooth transition, which reduces the friction and resistance of the material when entering the adjustment structure, and avoids material wear and energy loss caused by friction. Specifically, by adding a feed channel 100, and designing it to be a square tube and smoothly docking with the upper buffer channel 200, the preliminary guidance and concentration of the material before entering the adjustment structure is achieved. This design not only ensures that the material can enter the upper buffer channel 200 in an orderly and stable manner, avoids the uneven flow rate and blockage problems caused by the dispersion or irregular flow of the material, but also further improves the stability and reliability of the entire adjustment structure to control the material flow rate. The gradually shrinking design of the cross-sectional area of ​​the feed channel 100 effectively improves the flow density of the material, so that the material can obtain a more uniform initial flow rate when entering the upper buffer channel 200, providing more favorable conditions for the subsequent deceleration effect of the upper rotating rod 1 and the blocking blade 2. At the same time, the smooth transition inner wall design reduces the friction between the material and the channel, reduces the degree of wear of the material, maintains the original physical properties of the material, and helps to improve the quality and uniformity of the grinding product.

[0029] In some embodiments, Figure 1-2As shown, the internal path of the feed channel 100 is in a zigzag shape, and the path away from the upper buffer channel 200 is in an inclined shape, and the path close to the upper buffer channel 200 is in a vertical shape. This design allows the material to first undergo a preliminary deceleration and flow direction adjustment along the inclined path after entering the feed channel 100, and then achieve a rapid and smooth transition of the material through the vertical path when approaching the upper buffer channel 200. Specifically, the zigzag design of the internal path of the feed channel 100, especially the inclined path away from the upper buffer channel 200, can effectively utilize the effect of gravity to gradually decelerate the material during the flow process. This design not only provides a pre-deceleration process for the material, but also helps the material to achieve a more uniform flow velocity distribution before entering the upper buffer channel 200, thereby improving the fineness and stability of the flow velocity control of the entire regulating structure. And because the material has been decelerated to a certain extent on the inclined path, the impact energy after entering the upper buffer channel 200 will also be reduced accordingly, thereby reducing the degree of wear of the material on the internal components of the channel. Through the design of the zigzag internal path, the material is more fully decelerated and adjusted in flow direction before entering the grinding system. This not only allows the material to enter the grinding equipment at a more suitable speed, but also ensures the uniform distribution of the material during the grinding process. These factors work together to improve the grinding efficiency, allowing the grinding roller or grinding disc to grind and crush the material more fully, thereby obtaining a grinding product with more uniform particle size and higher quality. The design of the zigzag internal path increases the flexibility of the feed channel 100, allowing it to adapt to materials of different types and properties. For materials with better fluidity or smaller particles, the inclined path can provide sufficient deceleration space; while for materials with poor fluidity or larger particles, the vertical path can ensure that the material enters the upper buffer channel 200 quickly and smoothly. This design makes the adjustment structure more adaptable and stable when dealing with different materials.

[0030] In some embodiments, Figure 2As shown, one side of the feed channel 100 is hinged to the corresponding side of the upper buffer channel 200, so that the feed channel 100 can be rotated relative to the upper buffer channel 200, thereby realizing the full opening or closing of the feed channel 100. When the feed channel 100 is fully opened, the upper buffer channel 200 is fully exposed, which is convenient for cleaning, inspecting or repairing the inside of the adjustment structure; when the feed channel 100 is closed, the feed channel 100 can be used for normal feeding operations. Specifically, through the hinged design, the feed channel 100 can be easily fully opened, so that the upper buffer channel 200 and the adjustment elements inside it (such as the upper rotating rod 1 and the blocking leaf 2) are fully exposed. In this way, the operator can more conveniently clean, inspect or repair the inside of the adjustment structure without disassembling or moving other parts, which greatly improves the convenience and efficiency of maintenance. The opening and closing function of the feed channel 100 enhances the flexibility of the entire adjustment structure. When cleaning, inspection or maintenance is required, the upper buffer channel 200 can be fully exposed by simply rotating the feed channel 100; during normal operation, the feed channel 100 can be tightly closed to ensure that the material can smoothly and stably enter the upper buffer channel 200 for deceleration and flow direction adjustment.

[0031] In some embodiments, the upper rotating rod 1 is externally connected to a motor that rotates in a forward and reverse pulse mode, and the motor is connected to the upper rotating rod 1 through a transmission device, and can drive the upper rotating rod 1 to perform intermittent rotation in the forward and reverse directions in the upper buffer channel 200. By externally connecting a motor that rotates in a forward and reverse pulse mode, the upper rotating rod 1 can perform intermittent rotation in the forward and reverse directions in the upper buffer channel 200. This rotation mode not only enhances the blocking and stirring ability of the upper rotating rod 1 on the material, but also makes the flow of the material in the upper buffer channel 200 more uniform and stable. The forward and reverse pulse operation helps to break the blockage or accumulation that may be formed in the channel, thereby further improving the control ability of the regulating structure on the flow rate and flow direction of the material. Moreover, since the upper rotating rod 1 can rotate in a forward and reverse direction, the regulating structure can better adapt to materials of different types and properties. For materials with poor fluidity or easy to be blocked, by adjusting the operating parameters of the motor (such as rotation frequency, rotation direction, etc.), more effective dispersion and stirring of the material can be achieved, ensuring that the material can pass smoothly through the upper buffer channel 200. Furthermore, the motor that operates in a forward and reverse pulsed manner can distribute the wear of the upper rotating rod 1 more evenly during the rotation process, thereby extending the service life of the upper rotating rod 1.

[0032] In some embodiments, Figure 3As shown, multiple upper rotating rods 1 are arranged side by side, and the blocking leaves 2 on adjacent upper rotating rods 1 are staggered, so that when the material passes through the upper buffer channel 200, it can be continuously blocked and stirred by multiple upper rotating rods 1 and their blocking leaves 2, thereby further enhancing the control ability of the material flow rate and flow direction. Specifically, multiple upper rotating rods 1 are arranged side by side, and the blocking leaves 2 on adjacent upper rotating rods 1 are staggered. This design enables the material to be continuously blocked and stirred by multiple upper rotating rods 1 and their blocking leaves 2 when passing through the upper buffer channel 200. This continuous blocking and stirring effect not only further slows down the falling speed of the material, but also makes the flow of the material in the upper buffer channel 200 more uniform and stable, thereby enhancing the control ability of the material flow rate and flow direction. In addition, the continuous blocking and stirring effect of multiple upper rotating rods 1 and their blocking leaves 2 helps to optimize the distribution of the material in the upper buffer channel 200. By adjusting the arrangement of the upper rotating rod 1 and the shape and distribution of the retaining blades 2, the material flow direction can be accurately guided, so that the material can achieve a more uniform flow velocity distribution before entering the lower buffer channel 300. This optimized material distribution not only improves the uniformity and efficiency of grinding, but also reduces the impact and wear of the material on the internal components of the grinding equipment. In addition, the design of multiple upper rotating rods 1 arranged side by side and the retaining blades 2 staggered distribution makes the wear and tear of each upper rotating rod 1 and its retaining blades 2 more uniform. This design helps to extend the service life of the upper rotating rod 1 and the retaining blades 2 and reduce the maintenance cost of the equipment. At the same time, since the flow of materials in the upper buffer channel 200 is more uniform and stable, this also reduces the impact and wear of materials on the lower buffer channel 300 and the internal components of the grinding equipment, thereby extending the service life of the entire grinding system.

[0033] In some embodiments, Figure 1-3 As shown, only one upper rotating rod 1 is connected to the power output end of the motor, and the other upper rotating rods 1 are transmitted through gears 3. This design simplifies the power transmission system, reduces the manufacturing cost and maintenance difficulty, and at the same time ensures the synchronous rotation between multiple upper rotating rods 1, thereby improving the stability and reliability of the operation of the adjustment structure. Specifically, by designing that only one upper rotating rod 1 is directly connected to the motor and the other upper rotating rods 1 are transmitted through gears 3, the power transmission system is greatly simplified. This design reduces the number of transmission components, reduces the complexity of the system and the manufacturing cost. At the same time, the simplified power transmission system also makes maintenance easier and reduces the maintenance cost of the equipment. Moreover, the transmission of gear 3 has the characteristics of accurate transmission ratio and high transmission efficiency. By connecting multiple upper rotating rods 1 through gear 3 transmission, the synchronous rotation between them can be ensured. This synchronous rotation ensures that multiple upper rotating rods 1 and their blocking blades 2 continuously and evenly block and stir the material, thereby improving the control accuracy and stability of the material flow rate and flow direction.

[0034] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
