DETAILED DESCRIPTION

[0027] It should be noted that, in the absence of conflict, the embodiments in this application and the technical features in the embodiments can be combined with each other, and the detailed description in the specific implementation method should be understood as an explanation of the purpose of this application and should not be regarded as an improper limitation on this application.

[0028] In the description of the embodiments of the present application, it should be noted that the terms "transmission direction of the ray", "height direction", "first direction", "second direction", etc. indicate the orientation or position relationship based on the orientation or position relationship shown in the drawings. These orientation terms are only for the convenience of describing the embodiments of the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the embodiments of the present application. The present application will be further described in detail below in conjunction with the drawings and specific embodiments.

[0029] The present application embodiment provides a solid material conveying device 10 for conveying solids that are prone to moisture absorption and agglomeration. Figure 1 to Figure 2 The solid material conveying device 10 includes a containing device 1, a stirring device 2 and a transport device 3. The containing device 1 has a containing chamber 11 and an opening 12, the opening 12 is connected to the containing chamber 11, and the opening 12 is arranged at the bottom of the containing device 1 along the height direction. The stirring device 2 includes a stirring member 21, the stirring member 21 is arranged in the containing chamber 11, the stirring member 21 extends along the height direction of the containing device 1, there is a first preset gap between the stirring member 21 and the cavity wall of the containing chamber 11, and the outer contour of the stirring member 21 matches the containing chamber 11. The transport device 3 is arranged below the containing device 1. The stirring member 21 can rotate along the axis of the containing device 1, driving the material in the containing chamber 11 from the gap between the stirring member 21 and the containing chamber 11, through the opening 12 into the transport device 3.

[0030] The solid material conveying device 10 is a device for transporting solid materials from one location to another. It realizes the orderly conveying of solid materials through the coordinated work of multiple components. It is widely used in many fields such as industrial production, warehousing and logistics, such as conveying granular raw materials in the chemical industry and conveying grains in the grain processing industry.

[0031] The containing device 1 is used as a storage container for solid materials, providing a temporary storage space for the materials. The containing device 1 has a specific shape and structure, and the internal containing cavity 11 determines the storage capacity of the materials.

[0032] For example, the inner wall of the accommodating chamber 11 can be designed as a smooth surface to reduce the friction between the material and the chamber wall and facilitate the flow of the material. At the same time, a wear-resistant coating can also be provided on the inner wall to increase the service life of the accommodating device 1.

[0033] In some embodiments, a feed port may be provided at the top of the containing device 1, and the feed port may be equipped with a sealing cover or a feed valve to prevent the material from overflowing or being contaminated by the outside during storage.

[0034] The opening 12 is arranged at the bottom of the receiving device 1 in the height direction and is connected to the receiving chamber 11. The design of this position is based on the principle of gravity, so that the solid material can naturally flow out of the receiving chamber 11 through the opening 12 under the action of gravity after stirring.

[0035] The size and shape of the opening 12 will affect the outflow speed and flow rate of the material. If the opening 12 is larger, the material outflow speed may be faster and the flow rate may be larger under the same other conditions; conversely, if the opening 12 is smaller, the material outflow is relatively slow. The specific size of the opening 12 is not limited here, and is determined according to actual needs.

[0036] The shape of the opening 12 can be designed according to the characteristics of the material and the conveying requirements. For example, the shape of the opening 12 can be circular, square, etc. The circular opening 12 has an advantage in force uniformity, which can reduce the local pressure of the material on the edge of the opening 12 during the outflow process, and is more suitable for some granular or fluid materials; the square opening 12 may be more convenient in certain specific installation layouts or docking with other equipment. For example, when the feed port of the transport device 3 is square, the square opening 12 is easier to be tightly connected with it, reducing the possibility of material leakage.

[0037] For example, a flow regulating device, such as a gate or a regulating valve, may be provided at the opening 12 to accurately control the outflow speed and flow rate of the material according to actual needs.

[0038] The stirring device 2 is composed of a stirring member 21, and its main function is to stir the solid material in the accommodating chamber 11. By stirring, the material can be prevented from agglomerating and bridging, so that the material remains in a loose state, ensuring that the material can flow evenly from the gap between the stirring member 21 and the accommodating chamber 11 to the transport device 3, thereby improving the stability and continuity of material transportation.

[0039] The stirring element 21 is a component in the stirring device 2 that directly contacts the material and produces a stirring effect. It extends along the height direction of the containing device 1, and its outer contour matches the containing cavity 11, so that it can cover the material to the greatest extent during the stirring process to ensure the stirring effect.

[0040] Exemplarily, the stirring device 2 can be connected to a motor or other power source to realize the rotation of the stirring element 21 through a transmission device (such as belt drive, gear drive, etc.), and a speed regulating device can be provided to adjust the stirring speed according to the properties of the material and the conveying requirements.

[0041] “There is a first preset gap between the stirring member 21 and the cavity wall of the containing cavity 11”, which means that the stirring member 21 is not installed in close contact with the cavity wall in the containing cavity 11, but maintains a certain distance from the cavity wall. This distance is pre-set, which is the so-called “first preset gap”. This gap is the key channel for solid materials to flow from the containing cavity 11 to the opening 12 after stirring. When the stirring member 21 rotates, it will drive the surrounding materials to move. The materials will pass through this gap under the push of the stirring member 21 and gradually move to the opening 12 at the bottom of the containing device 1. If there is no such gap, it will be difficult for the material to flow between the stirring member 21 and the cavity wall, which will cause the material transportation to be obstructed.

[0042] Maintaining a certain gap can reduce the collision between the stirring member 21 and the wall of the accommodating chamber 11 during high-speed rotation. The continuous rotation of the stirring member 21 may cause deviation due to some unforeseen factors (such as vibration, uneven distribution of materials, etc.). The preset gap provides a certain tolerance space for the movement of the stirring member 21, preventing damage to the stirring member 21 and the wall of the accommodating chamber 11 due to collision, thereby extending the service life of the equipment.

[0043] The specific size of the "first preset gap" is not limited here, and the size of the gap should be determined according to the particle size, shape, fluidity and other characteristics of the solid material. The size of the gap will also affect the stirring effect. A smaller gap can enable the stirring member 21 to produce a stronger shear force on the material close to the cavity wall, thereby improving the uniformity of stirring. However, if the gap is too small, it may increase the resistance to material flow and even cause material blockage. Therefore, it is necessary to comprehensively consider the stirring effect and the smooth flow of the material during design, and determine a suitable first preset gap through experiments or simulations.

[0044] “The outer contour of the stirring member 21 matches the accommodating chamber 11” means that the shape and size design of the stirring member 21 is closely combined with the shape and internal space of the accommodating chamber 11. For example, if the accommodating chamber 11 is cylindrical, the stirring member 21 may be a cylindrical stirring shaft or a spiral structure around the central axis of the cylinder; if the accommodating chamber 11 is square, the outer shape of the stirring member 21 will also be designed to roughly fit the outline of the square cavity wall, such as having corresponding stirring structures near the four corners and each side.

[0045] This matching design can ensure that the stirring member 21 fully contacts the material in the accommodating chamber 11 during the rotation process. Because the shape of the stirring member 21 can cover the space of the accommodating chamber 11 to the greatest extent, the stirring action can cover the material at almost all positions in the accommodating chamber 11, and there will be no "dead corners" where a large amount of material cannot be stirred.

[0046] The transport device 3 is located below the receiving device 1 and is responsible for receiving the solid material flowing out of the opening 12 of the receiving device 1 and transporting it to a designated location. It can be in various forms such as a conveyor belt and a screw conveyor, which can be selected according to different material properties and transportation requirements.

[0047] The specific structure of the transport device 3 is not limited here. For example, the storage device 1 is transported by a conveyor belt, and the conveyor belt can be made of a non-slip and wear-resistant material, and the appropriate conveyor belt length and inclination angle can be set according to the transport distance and site conditions.

[0048] The solid material conveying device 10 provided in the embodiment of the present application is provided with a stirring member 21 in the receiving chamber 11 of the receiving device 1. The stirring action of the stirring member 21 effectively reduces the blockage caused by the solid material agglomerating in the receiving chamber 11. There is a first preset gap between the stirring member 21 and the cavity wall of the receiving chamber 11, and the stirring member 21 extends along the height direction of the receiving chamber 1 and its outer contour matches the receiving chamber 11. By reasonably designing the size of the first preset gap, the stirring member 21 can fully stir the materials at different positions in the receiving chamber 11 under appropriate stirring resistance, so that the materials are evenly distributed when entering the transport device 3, reducing the situation where the transport device 3 is partially overloaded or empty due to uneven accumulation of materials, and improving the working efficiency and service life of the transport device 3.

[0049] In some embodiments, see Figure 1 to Figure 2 In the cross section perpendicular to the height direction of the accommodating device 1 , the cross-sectional area of ​​the accommodating cavity 11 decreases from the top to the bottom of the accommodating device 1 .

[0050] The height direction of the accommodating device 1 refers to the vertical direction from the bottom to the top of the accommodating device 1 as shown in the drawings.

[0051] The cross-sectional area of ​​the accommodating cavity 11 is the size of the plane area occupied by the accommodating cavity 11 in a plane cut perpendicular to the height direction of the accommodating device 1. The cross-sectional areas at different positions reflect the changes in the spatial size of the accommodating cavity 11 at different heights.

[0052] The area of ​​the cross section perpendicular to the height direction gradually decreases. For example, if the container 1 is a funnel-shaped structure, it has a larger circular or other shaped cross section at the top, and as it approaches the bottom, the area of ​​the circular or other shaped cross section gradually shrinks and becomes smaller until it reaches the position where the bottom is connected to the opening 12, and its cross-sectional area reaches the minimum, and the minimum cross-sectional area is associated with the area of ​​the opening 12.

[0053] For example, the accommodating device 1 includes, from top to bottom, a section with a constant cross-section area on a section perpendicular to the height direction, a funnel section with a gradually decreasing area on a section perpendicular to the height direction, and a section with a constant cross-section area on a section perpendicular to the height direction. For example, the two sections with a constant cross-section are cylindrical, and the two ends of the funnel section are two cylindrical structures, one large and one small.

[0054] For example, the inner wall of the accommodating chamber 11 can be designed as a smoothly transitioned curved surface, gradually shrinking from a larger cross-section at the top to a smaller cross-section at the bottom. This can reduce jamming and accumulation of materials during the flow process, and allow the materials to slide naturally along the inner wall. For example, a portion of a conical surface can be used to construct the inner wall of the accommodating chamber 11, so that the materials can smoothly gather along the conical surface toward the opening 12 at the bottom under the action of gravity.

[0055] Since the cross-sectional area decreases from the top to the bottom, the material will naturally gather and flow to the bottom under the action of gravity. This shape is similar to a funnel, which can guide the material to flow smoothly to the opening 12, reducing the possibility of stagnation or blockage of the material in the receiving chamber 11. Even if the fluidity of the material is poor, it can gradually move to the outlet under the action of gravity and self-accumulation in the receiving chamber 11 of this shape, thereby improving the smoothness of material transportation.

[0056] In some embodiments, see Figure 1 to Figure 2 The stirring member 21 has a symmetrical structure, and the central axis of the stirring member 21 coincides with the central axis of the containing device 1 .

[0057] Symmetrical structure means that the stirring element 21 has certain symmetry in shape, size or mass distribution. For example, the stirring element 21 may be left-right symmetrical, top-bottom symmetrical or rotationally symmetrical on a certain plane or axis. This symmetry makes the stirring element 21 evenly stressed during movement and moves more smoothly.

[0058] The stirring member 21 has a symmetrical structure, and its central axis coincides with the central axis of the containing device 1. This means that the stirring member 21 is arranged in a uniform and symmetrical manner in the containing device 1. For example, if the stirring member 21 is a structure similar to a propeller, and its central axis coincides with the central axis of the containing device 1, then during the stirring process, the forces of the various blades of the propeller about the central axis and the effects on the material are balanced.

[0059] Since the central axis of the stirring member 21 coincides with the central axis of the receiving device 1, the stirring member 21 is evenly stressed during rotation. Eccentric vibration or deviation will not occur due to uneven stress, which reduces the risk of friction and collision between the stirring member 21 and the cavity wall of the receiving device 1, and prolongs the service life of the device. At the same time, the stable operation state also reduces the noise during the operation of the device.

[0060] In some embodiments, see Figure 1 to Figure 2 , the first preset gap is greater than or equal to 1 cm and less than or equal to 3 cm.

[0061] The specific size of the first preset gap is not limited here, for example, it can be 1 cm, 1.2 cm, 1.4 cm, 1.6 cm, 1.8 cm, 2 cm, 2.2 cm, 2.4 cm, 2.6 cm, 2.8 cm, 3 cm, etc.

[0062] By setting the first preset gap within the above range, most common solid materials can flow smoothly between the stirring element 21 and the cavity wall. There will be no blockage due to a gap that is too small, ensuring the continuity of material transportation. This gap range enables the stirring element 21 to have a moderate stirring effect on the material. The material will not be fully stirred due to a gap that is too large, resulting in material agglomeration or uneven mixing, nor will the stirring resistance of the stirring element 21 be too large due to a gap that is too small, affecting the stirring efficiency. When the first preset gap is within the specified range, the friction between the stirring element 21 and the cavity wall is relatively reasonable. There will be no excessive wear due to a gap that is too small, reducing the maintenance and replacement costs of the equipment; at the same time, the stirring element 21 will not consume too much energy to push the material due to a gap that is too large, reducing the operating energy consumption of the equipment and improving the overall economy and service life of the equipment.

[0063] In some embodiments, see Figure 1 to Figure 2 The stirring member 21 is a plate-shaped structure, and a hollow area 211 matching the outer contour of the stirring member 21 is provided inside the stirring member 21 .

[0064] Plate-like structure: means that the stirring element 21 has a shape similar to a plate, with a certain area and thickness. Compared with stirring elements 21 of other shapes (such as rod-shaped, spiral-shaped, etc.), the plate-like structure can provide a larger contact area when in contact with the material, thereby generating different force distribution and stirring effects on the material.

[0065] The hollow area 211 is an empty area formed by removing part of the material inside the stirring member 21. The shape of this area matches the outer contour of the stirring member 21, which means that the shape and size of the hollow area 211 are designed based on the overall shape characteristics of the stirring member 21, and the two have a certain consistency or coordination in geometry.

[0066] The stirring member 21 is in a plate-like structure, and has a hollow portion inside that matches its own outer contour. For example, if the stirring member 21 is a circular plate-like structure, then the hollow area 211 may also be circular or composed of a plurality of geometric shapes associated with the circular contour, and its position and size are distributed inside the stirring member 21. During the stirring process, the plate-like stirring member 21 uses its own planar structure to push and flip the material, and the hollow area 211 changes the flow path and force of the material around the stirring member 21.

[0067] By providing the hollow area 211, the overall weight of the stirring member 21 is reduced. During the operation of the stirring device 2, the lighter stirring member 21 requires relatively less power input, thereby reducing energy consumption. For example, in large-scale industrial production, the use of such a lightweight stirring member 21 in a solid material conveying device 10 that runs for a long time can significantly save energy costs. When the plate-like stirring member 21 stirs some viscous materials, it is easy for the material to adhere to the surface of the stirring member 21. The presence of the hollow area 211 reduces the contact area between the stirring member 21 and the material, reducing the possibility of material adhesion. At the same time, during the stirring process, the movement of the material in and out of the hollow area 211 also helps to peel off the adhering material, ensuring the continuous and effective operation of the stirring member 21.

[0068] In some embodiments, see Figures 1 to 3 The stirring member 21 includes a first rod 212, a second rod 213 and two third rods 214. The third rod 214 extends along the height direction of the accommodating device 1, and one end of the two third rods 214 is respectively connected to the two ends of the first rod 212 along the extension direction, and the other ends of the two third rods 214 are respectively connected to the same end of the second rod 213 along the extension direction. One end of the second rod 213 away from the third rod 214 extends toward the direction close to the opening 12. The first rod 212, the second rod 213 and the third rod 214 define a hollow area 211.

[0069] The first rod 212 is an important structural component of the stirring element 21, and plays the role of a basic frame in the structural layout of the entire stirring element 21. It cooperates with other rods to define the hollow area 211 and form a stable structural form to achieve effective action on the material.

[0070] The second rod 213 is also a component of the stirring member 21, and cooperates with the first rod 212. Through the connection relationship with the first rod 212 and the third rod 214, they jointly construct the overall structure of the stirring member 21, and participate in defining the hollow area 211, affecting the flow path and force conditions of the material around and inside the stirring member 21.

[0071] The second rod 213 can be designed to be curved, such as an arc, so that the hollow area 211 formed by connecting it with the first rod 212 and the third rod 214 is more irregular, so that the material can have a more complex and changeable flow path during stirring, thereby enhancing the stirring effect. In addition, the thickness of the second rod 213 can also be changed according to the actual stress conditions, and the part that bears greater connection force and material impact force can be appropriately thickened to improve the structural strength.

[0072] The third rod 214 is formed by extending the two ends of the first rod 212 along the height direction of the containing device 1, and it serves as a bridge connecting the first rod 212 and the second rod 213. Through this connection, the rods are interconnected to jointly form a specific hollow area 211, and the stability of the overall structure of the stirring member 21 is enhanced, ensuring that a stable force can be applied to the material during the stirring process.

[0073] The connection between the first rod 212 or the second rod 213 and the third rod 214 can be welded to ensure the firmness of the connection. Alternatively, they can be connected by threads to facilitate disassembly and replacement, and can be quickly repaired when the stirring member 21 is partially damaged. At the same time, a reinforcement structure can be set at the connection, such as adding a connecting sleeve, a reinforcing rib, etc., to enhance the stability of the overall structure and prevent the connection from loosening during the stirring process.

[0074] Due to the hollow area 211 defined by the first rod 212, the second rod 213 and the third rod 214, the material has a more complex flow path during the stirring process. The material will not only flow along the surface of the rod, but also shuttle and roll in the hollow area 211, and the materials at different positions can be fully mixed. Compared with the stirring member 21 with a simple structure, it can more effectively break the material agglomeration, improve the uniformity of the material, and ensure the stability of the quality of the material transported to the transport device 3.

[0075] A stable frame structure is formed by connecting the rods to each other, especially the third rod 214 to connect the first rod 212 and the second rod 213. During stirring, even if subjected to uneven impact force and stirring resistance of the material, the entire stirring member 21 can maintain good structural stability, reduce deformation, looseness, etc., extend the service life of the stirring member 21, and reduce the maintenance cost of the equipment.

[0076] In some embodiments, see Figure 1 to Figure 2 The stirring device 2 includes a rotating shaft 22 , which is connected to the first rod 212 , and the central axis of the rotating shaft 22 coincides with the central axis of the stirring member 21 .

[0077] The rotating shaft 22 is a key component in the stirring device 2 and is the core support and power transmission component for the rotation of the stirring member 21. It connects the power source (such as a motor) and the stirring member 21, transmits power to the stirring member 21, and makes it rotate around a specific axis, thereby generating a stirring effect on the material.

[0078] The connection between the rotating shaft 22 and the first rod 212 can be a key connection, and key grooves are respectively processed at the connection parts of the rotating shaft 22 and the first rod 212, and the torque is transmitted by installing keys. This connection method has a simple and reliable structure and can effectively ensure the power transmission between the rotating shaft 22 and the stirring member 21. In addition, a spline connection can also be used. The spline has multiple key teeth, which can transmit a larger torque and the connection is tighter, which is suitable for the needs of large or high-power stirring devices 2.

[0079] A reinforcing sleeve or a material thickness of the connecting area may be provided at the connecting portion between the rotating shaft 22 and the first rod 212. The reinforcing sleeve may be made of high-strength alloy steel, sleeved on the outside of the connecting portion, and fixed to the rotating shaft 22 and the first rod 212 by interference fit or welding, etc., to enhance the strength and rigidity of the connecting portion, and prevent the connection from being loosened or damaged due to excessive force during the stirring process.

[0080] The rotating shaft 22 is connected to the first rod 212 in the stirring member 21, and the central axis of the rotating shaft 22 coincides with the central axis of the stirring member 21. This means that the stirring member 21 rotates in an extremely symmetrical and stable manner during the rotation process. For example, if the stirring member 21 is a structure with a specific shape and a hollow area 211 composed of the above-mentioned first rod 212, the second rod 213 and the third rod 214, and its central axis is determined, then the rotating shaft 22 connected thereto is set along the straight line position of this central axis, so that when the stirring member 21 rotates around the central axis of the rotating shaft 22 (that is, its own central axis) under power drive, each part is evenly stressed, and uneven stirring or excessive vibration of the equipment will not occur due to problems such as eccentricity.

[0081] In some embodiments, the rotating shaft 22 is connected to a driving member, and the driving member drives the rotating shaft 22 to rotate, thereby enabling the stirring member 21 to rotate, wherein the driving member can be a power device such as an electric motor.

[0082] In some embodiments, see Figure 1 to Figure 2 The third rod 214 includes a first connecting segment 2141 and a second connecting segment 2142 connected to each other. The first connecting segment 2141 is connected to the first rod 212, and the second connecting segment 2142 is connected to the second rod 213. The distance between the first connecting segments 2141 of the two third rods 214 is the same, and the distance between the second connecting segments 2142 of the two third rods 214 gradually decreases from the top to the bottom of the accommodating device 1.

[0083] The first connecting section 2141 is a part of the third rod 214, and its main function is to connect with the first rod 212. It is the part that realizes the connection between the third rod 214 and the key first rod 212 in the main structure of the stirring member 21, ensuring the correlation and integrity between the various components of the entire stirring member 21.

[0084] The second connecting section 2142 is also a component of the third rod 214, which is responsible for connecting with the second rod 213 and cooperating with the first connecting section 2141, so that the third rod 214 can build a stable connection bridge between the first rod 212 and the second rod 213, and jointly construct the complete structure of the stirring element 21, affecting the flow characteristics of the material in the space enclosed by each rod.

[0085] The specific structure of the third rod 214 and the changing characteristics of the distance between its two connecting sections. The third rod 214 is divided into a first connecting section 2141 and a second connecting section 2142 which are connected to each other, wherein the first connecting section 2141 is connected to the first rod 212, and the second connecting section 2142 is connected to the second rod 213, forming a complete connection relationship. In addition, the distance between the first connecting sections 2141 corresponding to the two third rods 214 remains the same, while the distance between the second connecting sections 2142 of the two third rods 214 gradually decreases from the top to the bottom along the accommodating device 1.

[0086] The two third rods 214 are like two inclined brackets. Their respective first connecting sections 2141 are located near the first rod 212 with a fixed distance between each other. As they extend toward the bottom, the second connecting sections 2142 are located near the second rod 213 and the distance between each other becomes narrower and narrower, presenting an overall layout that is narrow at the bottom and wide at the top. Such a structure can meet the requirement that the stirring member 21 and its outer contour match the accommodating cavity 11.

[0087] In some embodiments, see Figure 1 to Figure 2 , the width of the first rod 212 is greater than the width of the second rod 213 .

[0088] In some embodiments, the width of the first rod 212 is greater than the width of the third rod 214 .

[0089] Width refers to the dimension perpendicular to its length. If the rod is a long object with the length direction as its main extension direction, then the width is a physical quantity that measures the thickness of the rod in the direction perpendicular to its length. For example, for a rod with a rectangular cross-section, the width is the dimension represented by the two short sides of the rectangle.

[0090] The larger width of the first rod 212 means that it has a larger cross-sectional area in contact with the material during the stirring process, which can provide a stronger stirring force and a larger stirring range. In addition, the width of the first rod 212 is greater than the width of the second rod 213 and the third rod 214, which is conducive to improving the structural strength of the overall connection.

[0091] In some embodiments, see Figure 1 to Figure 2 The wall surface of the hollow area 211 is a smooth surface.

[0092] The wall surface here specifically refers to the surface surrounded by the rods around the hollow area 211. It is in direct contact with the material flowing through the hollow area 211, and its surface characteristics will have a significant impact on the flow behavior and stirring process of the material.

[0093] A smooth surface means that the wall has no obvious protrusions, depressions, edges or rough textures, and the surface is relatively flat and smooth. At the microscopic level, its surface roughness value is low. Such surface characteristics are conducive to the smooth sliding and flow of materials on its surface.

[0094] For example, polishing the wall surface can improve the smoothness of the wall surface. For example, mechanical polishing, chemical polishing or electrochemical polishing can be used to remove processing marks and tiny flaws on the rod surface, so that the wall surface can achieve higher flatness and glossiness. In addition, the wall surface can also be treated with nano-coating, such as nano-silicon dioxide coating, which can fill the tiny pores on the rod surface at the microscopic level, further reduce the surface roughness, and also have certain anti-fouling and wear-resistant properties.

[0095] At the connection between the wall of the hollow area 211 and other parts of the rod, a smooth transition arc or inclined surface is designed. This can avoid right angles or sharp edges at the connection, and prevent materials from accumulating or getting stuck at these locations. For example, at the corner where the first rod 212 and the third rod 214 are connected to form the wall of the hollow area 211, a circular arc with a larger radius is used for transition, so that the material can naturally flow from the rod surface to the wall of the hollow area 211 without being blocked by the sudden change of the corner.

[0096] The hollow area 211 surrounded by the first rod 212, the second rod 213 and the third rod 214 has a smooth wall surface. For example, when the material enters the hollow area 211 during the stirring process, since the wall surface is smooth, the material will not be stuck or excessively collided due to the irregularity of the wall surface, and can flow along the wall surface more smoothly, making the movement trajectory of the material in the hollow area 211 more smooth and continuous, thereby promoting uniform mixing of the material around and inside the entire stirring member 21.

[0097] The smooth wall surface can effectively reduce the adhesion of materials on the wall surface of the hollow area 211. Since there is no adsorption and obstruction of the rough surface, the material is not easy to adhere to it when passing through the wall surface, which reduces the probability of problems such as the increase in weight of the stirring member 21, the decrease in stirring efficiency, and the clogging of the hollow area 211 by the material due to the adhesion of the material. When the material flows in the hollow area 211 of the smooth wall surface, the friction force is small, so that the resistance encountered by the stirring member 21 during the rotation process is reduced, thereby reducing the energy consumption of the equipment.

[0098] In some embodiments, see Figure 1 to Figure 2 The transport device 3 includes a screw feeding assembly 31 , and the screw feeding assembly 31 includes a screw 311 and a transport tube 312 . The screw 311 is disposed in the transport tube 312 , and the accommodating device 1 is connected to the transport tube 312 through the opening 12 .

[0099] The screw feed assembly 31 utilizes the rotational motion of the screw 311 in the transport pipe 312 to push the solid material forward. The screw 311, as a core component, transports the material along the transport pipe 312 through the interaction between its spiral blades and the material. It has good sealing and precise transport volume control capabilities, and is suitable for the transportation of a variety of solid materials, especially for some materials with poor fluidity or requiring quantitative transportation.

[0100] The screw 311 is a key moving part in the screw feed assembly 31, and usually has a spiral blade structure. When the screw 311 rotates, the spiral blades will generate axial thrust and circumferential friction on the material, so that the material moves along the axial direction of the screw 311 in the conveying pipe 312. Its shape, pitch, diameter and other parameters will be designed and adjusted according to the material characteristics and conveying requirements.

[0101] The transport pipe 312 serves as a conveying channel for the material, provides an installation space for the screw 311 and defines the conveying path of the material. It is usually a tubular structure with certain strength and sealing, and a certain gap is maintained between its inner wall and the screw 311 to allow the screw 311 to rotate and push the material through, while preventing the material from leaking into the external environment.

[0102] It should be noted that the pitch of the screw 311 should be close to the diameter of the transport pipe 312. If the pitch is too large, more materials will remain between the pitches, which is not conducive to transporting all the materials in the pipeline. If the pitch is too small, the screw 311 will be stuck during transportation due to moisture absorption by the material, resulting in the screw 311 being unable to operate normally.

[0103] The screw 311 is installed inside the transport pipe 312, and the opening 12 at the bottom of the receiving device 1 is connected to the transport pipe 312. When the screw 311 rotates in the transport pipe 312, the solid material falling from the receiving device 1 through the opening 12 into the transport pipe 312 will be pushed by the spiral blades of the screw 311 and gradually move forward along the axial direction of the transport pipe 312, thereby realizing the material transportation process from the receiving device 1 to the transport pipe 312. For example, in chemical production, for some powdered or granular raw materials, the screw feeding assembly 31 can accurately transport the raw materials from the receiving device 1 where the raw materials are stored to the reaction equipment or the processing equipment of the next process.

[0104] In some embodiments, the screw rod 311 is connected to a driving member, and the driving member drives the screw rod 311 to rotate, wherein the driving member can be a power device such as an electric motor.

[0105] The screw feed assembly 31 can accurately control the conveying flow rate of solid materials. By adjusting the rotation speed of the screw 311, the material flow rate can be linearly adjusted. The screw feed assembly 31 can accurately control the conveying flow rate of solid materials. By adjusting the rotation speed of the screw 311, the material flow rate can be linearly adjusted. During the process of the screw 311 rotating and conveying the material in the transport pipe 312, the entire system has good sealing. The material is confined in the transport pipe 312 and is not easy to leak into the external environment, reducing the waste of materials and the pollution to the surrounding environment.

[0106] In some embodiments, see Figure 1 to Figure 2 The stirring member 21 and the screw 311 have a second preset gap, and the second preset gap is greater than or equal to 0.5 cm and less than or equal to 2 cm.

[0107] The specific size of the second preset gap is not limited here, for example, it can be 0.5cm, 0.6cm, 0.7cm, 0.8cm, 0.9cm, 1cm, 1.1cm, 1.2cm, 1.3cm, 1.4cm, 1.5cm, 1.6cm, 1.7cm, 1.8cm, 1.9cm, 2cm, etc.

[0108] It is stipulated that the value range of the second preset gap between the stirring element 21 and the screw 311 is between 0.5cm and 2cm, and this range is determined by comprehensively considering multiple factors. For example, for common solid material conveying scenarios, such as conveying medium-sized plastic particles or mineral raw materials, this gap range can ensure that the materials smoothly transition from the stirring area to the transportation area while enabling the respective functions of the stirring element 21 and the screw 311 to be effectively exerted. If the gap is too small, it may cause the material to flow poorly between the two, or even cause blockage, and at the same time increase the risk of mutual interference between the stirring element 21 and the screw 311, affecting the normal operation of the equipment; if the gap is too large, the material may not be effectively guided and controlled during the transition process, resulting in uneven material distribution, affecting subsequent transportation and use effects.

For those skilled in the art, the present application can have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application are included in the protection scope of the present application.
