Description

Technical Field

[0001] The present invention relates to the technical field of supporting equipment for transporting spherical materials, and particularly relates to a spherical material lifting device. Background Art

[0002] As a relatively common type of material, spherical materials are quite common in the production and logistics operations of various industries. Especially in the current nuclear industry, the high-temperature gas-cooled reactor fuel handling system used in nuclear reactors usually uses pneumatic conveying to transport spherical fuel elements through a lifting pipe to the top of the reactor core, and then discharges the spherical fuel elements from the bottom of the reactor core through a gravity pipe, so as to realize that the spherical fuel elements pass through the reactor core multiple times and continuous loading and unloading under the condition of not shutting down the reactor, so as to meet the continuous operation requirements of the process flow.

[0003] Among them, the lifting of spherical fuel elements, as the main function of the fuel handling system, is required to lift the unburned spherical fuel elements discharged from the discharge pipe at the lower part of the reactor pressure vessel to the reactor core for recirculation, or to lift the burned spherical fuel elements to the discharge temporary storage device for unloading. Therefore, the equipment for supporting the lifting and conveying of spherical fuel elements, as one of the most important devices in the fuel handling system, its effectiveness is crucial.

[0004] At present, in the nuclear industry, the lifting and conveying of spherical fuel elements still mostly adopt the pneumatic conveying method. Specifically, the pneumatic conveying method uses positive-pressure high-speed gas as the power to lift the spherical fuel elements in the spherical pipe to the top of the reactor core. Although this pneumatic conveying method has the advantages of flexible layout, airtightness and continuous conveying, the energy consumption of the supporting high-speed gas supply device is relatively high, the overall energy consumption of the equipment is large, the lifting speed of the spherical fuel elements in the pipe is not stable, and the high-speed gas has a large impact on the airflow of the spherical fuel elements in the pipe, resulting in easy structural damage to both the spherical fuel elements and the inner wall of the pipe, and generating a large amount of debris and dust. After the equipment runs for a long time, the accumulated debris and dust are extremely easy to block the pipeline, thus hindering the lifting and conveying of spherical fuel elements, restricting the lifting and conveying efficiency of spherical fuel elements, and having an adverse impact on the efficient operation of related system equipment such as nuclear reactors.

[0005] In view of this, how to optimize the lifting and conveying method of spherical materials to make its lifting and conveying process more stable and efficient, and reduce the wear of spherical materials during the conveying process is an important technical problem that those skilled in the art need to solve at present. Summary of the Invention

[0006] The purpose of the present invention is to provide a spherical material lifting device, which has a stable and efficient lifting and conveying process for spherical materials, and the wear of spherical materials during the conveying process is small.

[0007] To solve the above technical problems, the present invention provides a spherical material lifting device, which includes a pressure-bearing cylinder with an axis extending in the vertical direction. A roller is coaxially inserted into the pressure-bearing cylinder, and a driving assembly capable of driving the roller to rotate around a fixed axis is arranged on the pressure-bearing cylinder;

[0008] A number of limiting wing plates are protrudingly arranged on the outer peripheral wall of the roller. The limiting wing plates extend in the vertical direction, and each of the limiting wing plates is evenly distributed at equal intervals in the circumferential direction of the roller. A material guiding groove capable of accommodating spherical materials is formed between two adjacent limiting wing plates;

[0009] A spiral material guiding strip is fixedly arranged on the inner peripheral wall of the pressure-bearing cylinder. The spiral material guiding strip spirally extends in the vertical direction to wind around the outer peripheral part of the limiting wing plate, and the extending direction of the spiral material guiding strip spirally ascends along the rotating direction of the roller. The spiral material guiding strip is in clearance fit with the limiting wing plate. The distance between the limiting wing plate and the pressure-bearing cylinder in the radial direction of the pressure-bearing cylinder is smaller than the outer diameter of the spherical material, and the distance between the roller and the spiral material guiding strip in the radial direction of the pressure-bearing cylinder is smaller than the outer diameter of the spherical material;

[0010] A material receiving port through which spherical materials enter the pressure-bearing cylinder is penetrated on the bottom side wall of the pressure-bearing cylinder. The inner wall of the material receiving port is higher than the bottom end of the spiral material guiding strip. When the material receiving port is aligned and communicated with the material guiding groove, the spherical materials enter the material guiding groove;

[0011] A material discharging port through which spherical materials are discharged from the pressure-bearing cylinder is penetrated on the top side wall of the pressure-bearing cylinder. The inner wall of the material discharging port is lower than the top end of the spiral material guiding strip. When the material discharging port is aligned and communicated with the material guiding groove, the spherical materials in the material guiding groove are discharged to the outside of the pressure-bearing cylinder through the material discharging port.

[0012] Preferably, a debris collection assembly is arranged at the bottom end of the pressure-bearing cylinder. The debris collection assembly is located below the roller and communicated with the inner cavity of the pressure-bearing cylinder.

[0013] Preferably, a slag discharging hole is penetrated at the center of the bottom end of the pressure-bearing cylinder. The debris collection assembly includes a debris guiding plate obliquely arranged at the bottom end of the inner cavity of the pressure-bearing cylinder to guide debris into the slag discharging hole. The debris collection assembly further includes a debris collection tank located below the pressure-bearing cylinder and a slag discharging pipe communicated between the inlet of the debris collection tank and the slag discharging hole.

[0014] Preferably, the spiral material guiding strip is fixedly connected with the inner peripheral wall of the pressure-bearing cylinder through a number of positioning buckles, and each of the positioning buckles is evenly distributed at equal intervals along the extending direction of the spiral material guiding strip;

[0015] Alternatively, the spiral material guiding strip is fixedly welded to the inner peripheral wall of the pressure bearing cylinder, and the welding positions are evenly distributed at equal intervals along the extension direction of the spiral material guiding strip.

[0016] Preferably, the driving assembly includes a transmission shaft coaxially inserted into the roller and a motor capable of driving the transmission shaft to rotate about a fixed axis, and the transmission shaft and the roller are circumferentially linked.

[0017] Preferably, an upper bearing support is fixedly arranged on the inner wall at the top end of the pressure bearing cylinder, a lower bearing support is fixedly arranged on the inner wall at the bottom end of the pressure bearing cylinder, the driving assembly further includes a top bearing installed in the middle of the upper bearing support and sleeved on the top end of the transmission shaft in a linked manner, and a bottom bearing installed in the middle of the lower bearing support and sleeved on the bottom end of the transmission shaft in a linked manner.

[0018] Preferably, an upper end plate extending horizontally is detachably connected to the top end of the pressure bearing cylinder, and the upper bearing support is arranged on the bottom wall of the upper end plate;

[0019] A lower end plate extending horizontally is detachably connected to the bottom end of the pressure bearing cylinder, and the lower bearing support is arranged on the top wall of the lower end plate.

[0020] Preferably, the motor is arranged on the top wall of the upper end plate, and the output shaft of the motor is coaxially and linkedly connected to the transmission shaft.

[0021] Preferably, a material guiding plate is arranged inside the pressure bearing cylinder, the material guiding plate is located above the top end of the roller, and the material guiding plate is in clearance fit with the top end of the roller. The two ends of the material guiding plate are respectively connected to the inner peripheral wall of the pressure bearing cylinder, and the middle of the material guiding plate is in clearance fit with the inner peripheral wall of the pressure bearing cylinder to form a discharge groove for spherical materials to pass through. The discharge groove communicates with the upstream of the discharge port along the conveying direction of the spherical materials.

[0022] Preferably, a discharge guiding groove extending obliquely in the vertical direction is arranged on the outer peripheral wall of the upper part of the pressure bearing cylinder, and the top end of the discharge guiding groove communicates with the downstream of the discharge port along the conveying direction of the spherical materials.

[0023] Preferably, a material receiving guiding groove extending obliquely in the vertical direction is arranged on the outer peripheral wall of the lower part of the pressure bearing cylinder, and the bottom end of the material receiving guiding groove communicates with the upstream of the material receiving port along the conveying direction of the spherical materials.

[0024] Compared with the above background art, in the operation process of the spherical material lifting device provided by the present invention, after the device is started, the driving component drives the roller to rotate. At this time, each limiting wing plate moves circumferentially along with the rotation of the roller. After the spherical material to be conveyed enters the pressure-bearing cylinder through the material receiving port, it directly rolls into the guiding groove between the two limiting wing plates that rotate past the material receiving port alignment position at this time, and is reliably supported on the spiral guiding strip. Then, the limiting wing plate behind the spherical material located in the guiding groove along the rotation direction abuts against the spherical material. Thus, as the roller continues to rotate, the limiting wing plate located behind synchronously pushes the spherical material to move circumferentially along the roller. Therefore, by utilizing the rolling cooperation between the spherical material supported on the spiral guiding strip and the spiral guiding strip, the spherical material is gradually lifted along the spiral extension structure of the spiral guiding strip until the spherical material moves to the discharge port, and the spherical material is sent out of the pressure-bearing cylinder through the discharge port to be conveyed to the downstream station equipment, completing the lifting operation of the spherical material. The spherical material lifting device uses the spiral guiding strip with spiral extension and the limiting wing plate that rotates circumferentially along with the roller to push the spherical material along the spiral guiding direction to achieve the stable lifting of the spherical material, greatly optimizing the position lifting effect of the spherical material, improving the lifting and conveying efficiency of the spherical material, and during the conveying process, the spiral guiding strip, which is the main supporting component of the spherical material, and the spherical material are in rolling cooperation, effectively reducing the structural wear of the spherical material and reducing the number of debris generated by the wear, thereby avoiding problems such as blockage or obstruction of the conveying space caused by excessive debris, and making the lifting and conveying process of the spherical material smoother and more fluent.

[0025] In another preferred embodiment of the present invention, a debris collection component is provided at the bottom end of the pressure-bearing cylinder. The debris collection component is located below the roller and communicates with the inner cavity of the pressure-bearing cylinder. After the conveyed spherical material, damaged spherical material, and carried dust debris enter the pressure-bearing cylinder through the material receiving port, they directly roll into the guiding groove between the two limiting wing plates opposite to the material receiving port. The spherical materials with larger sizes can be reliably supported on the spiral guiding strip; the small-sized damaged spherical materials and dust debris fall through the upper and lower through-structure of the guiding groove and the clearance between the two sides of the spiral guiding strip and the limiting wing plate and the pressure-bearing cylinder, and are collected at the debris collection component, so that the debris collection component can fully collect these debris, facilitating the subsequent centralized treatment of the debris, so as to prevent these debris from floating and adhering in the internal space of the pressure-bearing cylinder, thereby eliminating the interference and obstruction of the debris to the movement process of the spherical material and the operation process of each moving component.

[0037] The core of the present invention is to provide a spherical material lifting device, which has a stable and efficient lifting and conveying process for spherical materials, and the wear of spherical materials during the conveying process is relatively small.

[0038] To enable those skilled in the art to better understand the solution of the present invention, the following will further elaborate on the present invention in conjunction with the accompanying drawings and specific embodiments.

[0039] It should be noted in advance that in the present invention, unless otherwise clearly specified and defined, terms such as "installation", "connection", "linkage", "fixation" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] In addition, in the present invention, unless otherwise clearly specified and defined, the first feature being "on" or "under" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features therebetween.

[0041] In addition, the first feature being "above", "over" and "on top of" the second feature includes that the first feature is directly above and obliquely above the second feature, or merely indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature being "under", "beneath" and "underneath" the second feature includes that the first feature is directly below and obliquely below the second feature, or merely indicates that the horizontal height of the first feature is lower than that of the second feature. The orientation or positional relationship indicated by terms such as "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be construed as a limitation to the present invention.

[0042] In the specific embodiment, as Figure 1 shown, the spherical material lifting device provided by the present invention includes a pressure-bearing cylinder 11 whose axis extends in the vertical direction. A roller 12 is coaxially inserted into the pressure-bearing cylinder 11, and a driving assembly capable of driving the roller 12 to rotate around a fixed axis is arranged on the pressure-bearing cylinder 11.

[0043] With reference to Figure 2 shown. A plurality of limiting wing plates 121 are protrudingly arranged on the outer peripheral wall of the roller 12. The limiting wing plates 121 extend in the vertical direction, and the limiting wing plates 121 are evenly distributed at equal intervals along the circumferential direction of the roller 12. A material guiding groove 122 capable of accommodating spherical materials is formed by clearance fit along the circumferential direction between two adjacent limiting wing plates 121.

[0044] On the inner peripheral wall of the pressure-bearing cylinder 11, a spiral material guide strip 111 is fixedly arranged. The spiral material guide strip 111 spirally extends in the vertical direction to wind around the outer peripheral part of the limit wing plate 121, and the extension direction of the spiral material guide strip 111 spirally ascends along the rotation direction of the roller 12. The spiral material guide strip 111 is in clearance fit with the limit wing plate 121. The distance between the limit wing plate 121 and the pressure-bearing cylinder 11 in the radial direction of the pressure-bearing cylinder 11 is smaller than the outer diameter of the spherical material, and the distance between the roller 12 and the spiral material guide strip 111 in the radial direction of the pressure-bearing cylinder 11 is smaller than the outer diameter of the spherical material. In this way, the spherical material will not escape through the fitting gaps between adjacent components, ensuring that the spherical material is always within the effective range of the material guide groove 122 during the lifting and conveying process and is always reliably supported by the spiral material guide strip 111, thereby further ensuring the smoothness of the lifting and conveying process of the spherical material.

[0045] On the bottom side wall of the pressure-bearing cylinder 11, there is a material receiving port 112 through which the spherical material enters the pressure-bearing cylinder 11. The inner wall of the material receiving port 112 is higher than the bottom end of the spiral material guide strip 111. When the material receiving port 112 is aligned and communicated with the material guide groove 122, the spherical material enters the material guide groove 122.

[0046] On the top side wall of the pressure-bearing cylinder 11, there is a material discharging port 113 through which the spherical material is discharged from the pressure-bearing cylinder 11. The inner wall of the material discharging port 113 is lower than the top end of the spiral material guide strip 111. When the material discharging port 113 is aligned and communicated with the material guide groove 122, the spherical material in the material guide groove 122 is discharged to the outside of the pressure-bearing cylinder 11 through the material discharging port 113.

[0047] Generally, the material for lifting and conveying treatment targeted in this solution is usually the spherical fuel element required during the operation of a nuclear reactor. However, considering that other types of spherical materials also often need to be processed in this field and related machining and logistics fields, this solution has no special design specifically for the nuclear industry. The equipment structure layout and component adaptation principles mentioned in this solution can be directly applied to the lifting and conveying operations of various spherical or quasi-spherical materials.

[0048] During the specific operation and use of the equipment, after the equipment is started, the driving component drives the roller 12 to rotate. At this time, each limiting wing plate 121 moves circumferentially along with the rotation of the roller 12. After the spherical materials to be conveyed enter the pressure-bearing cylinder 11 through the material receiving port 112, they directly roll into the material guiding groove 122 between the two limiting wing plates 121 that are rotating past the alignment position of the material receiving port 112 at this time, and are reliably supported on the spiral material guiding strip 111. Then, the limiting wing plate 121 located behind the spherical materials in the material guiding groove 122 abuts against the spherical materials along the rotation direction. Thus, as the roller 12 continues to rotate, the limiting wing plate 121 located behind synchronously pushes the spherical materials to move circumferentially along the roller 12. Therefore, by utilizing the rolling cooperation between the spherical materials supported on the spiral material guiding strip 111 and the spiral material guiding strip 111, the spherical materials are gradually lifted along the spiral extension structure of the spiral material guiding strip 111 until the spherical materials move to the discharge port 113, and the spherical materials are sent out of the pressure-bearing cylinder 11 through the discharge port 113 to be conveyed to the downstream station equipment, completing the lifting operation of the spherical materials. The spherical material lifting equipment utilizes the spiral material guiding strip 111 with a spiral extension and the limiting wing plate 121 that rotates circumferentially along with the roller 12 to push the spherical materials along the spiral guiding direction to achieve the stable lifting of the spherical materials, greatly optimizing the position lifting effect of the spherical materials, improving the lifting and conveying efficiency of the spherical materials, and during the conveying process, the spiral material guiding strip 111, which is the main supporting component of the spherical materials, has a rolling cooperation with the spherical materials, effectively reducing the structural wear of the spherical materials, reducing the number of debris generated by the wear, and further avoiding problems such as blockage or obstruction of the conveying space caused by excessive debris, making the lifting and conveying process of the spherical materials smoother and more fluent.

[0049] It is not difficult to understand that the fitting position of the spherical materials in the material guiding groove 122 can directly refer to Figure 2 the spherical position marked by the dotted line at point A in Figure 3 or can also refer to the spherical position marked by the dotted line at point C in

[0050] It should be noted that the cross-section of the limiting wing plate 121 is usually a straight plate-like structure extending along the radial direction of the roller 12 as shown in the figure. However, considering the application requirements under some special working conditions, or for the material conveying operation that needs to be specially processed, the cross-section of the limiting wing plate 121 can also be an inclined extension or an arc-shaped structural component. In actual applications, the shape and structural layout of the limiting wing plate 121 can be flexibly selected and adjusted according to the specific working conditions. In principle, as long as it can meet the application requirements of the spherical material lifting equipment, it is acceptable.

[0051] On this basis, a debris collection assembly is provided at the bottom end of the pressure-bearing cylinder 11. The debris collection assembly is located below the roller 12 and communicates with the inner cavity of the pressure-bearing cylinder 11. After the transported spherical materials, damaged spherical materials, and carried dust debris enter the pressure-bearing cylinder 11 through the material receiving port 113, they directly roll into the material guiding groove 122 between the two limiting wing plates 121 opposite to the material receiving port 113. The spherical materials with larger sizes can be reliably supported on the spiral material guiding strip 111; the damaged spherical materials with smaller sizes and the dust debris fall through the upper and lower through-structure of the material guiding groove 122 and the clearance between the two sides of the spiral material guiding strip 111 and the limiting wing plates 121 and the pressure-bearing cylinder 11, and are collected at the debris collection assembly, so that the debris collection assembly can fully collect these debris, which is convenient for subsequent centralized treatment of the debris, so as to prevent these debris from floating and adhering in the internal space of the pressure-bearing cylinder 11, thereby eliminating the interference and obstruction of the debris to the movement process of the spherical materials and the operation process of each moving part.

[0052] Specifically, a slag discharge hole 114 penetrates through the center of the bottom end of the pressure-bearing cylinder 11. The debris collection assembly includes a debris guiding plate 131 that is inclinedly arranged at the bottom end of the inner cavity of the pressure-bearing cylinder 11 to guide the debris into the slag discharge hole 114. The debris collection assembly also includes a debris collection tank 13 located below the pressure-bearing cylinder 11 and a slag discharge pipe 132 that communicates between the inlet of the debris collection tank 13 and the slag discharge hole 114. Arranging the debris collection tank 13 outside the pressure-bearing cylinder 11 is convenient for unloading the debris collection tank 13 in time when there is more debris collected in the debris collection tank 13 and transferring the collected debris to the processing equipment at the downstream station. Generally, the debris guiding plate 131 is an integral conical structure. The top end of the debris guiding plate 131 abuts against the inner peripheral wall of the pressure-bearing cylinder 11, and the bottom end of the debris guiding plate 131 abuts against the inner wall of the pressure-bearing cylinder 11 at the edge of the slag discharge hole 114, so that the debris guiding plate 131 can cover the entire lateral extension space of the pressure-bearing cylinder 11, ensuring that the debris falling from above can all fall onto the debris guiding plate 131 and smoothly slide into the slag discharge hole 114 along the inclined arrangement structure of the debris guiding plate 131 under the action of its own gravity, thereby further improving the collection and discharge efficiency of the debris.

[0053] In addition, the spiral material guiding strip 111 and the inner peripheral wall of the pressure-bearing cylinder 11 can be in clearance fit or closely attached arrangement; correspondingly, the spiral material guiding strip 111 and the inner peripheral wall of the pressure-bearing cylinder 11 are fixedly connected by a plurality of positioning buckles 115, and the positioning buckles 115 are evenly distributed at equal intervals along the extension direction of the spiral material guiding strip 111. The positioning buckles 115 can provide uniform and reliable structural support for each part of the spiral material guiding strip 111 to ensure the overall extension tracking and structural extension accuracy of the spiral material guiding strip 111, thereby correspondingly ensuring the spiral lifting and transportation accuracy and conveying efficiency of the spherical materials.

[0054] Of course, the spiral guiding strip 111 and the inner peripheral wall of the pressure-bearing cylinder 11 can also be fixed by welding, and the welding positions are evenly distributed at equal intervals along the extension direction of the spiral guiding strip 111. The connection structure of welding fixation is simple and reliable, and the corresponding welding fixation operation process is relatively simple and easy to perform, which can optimize the assembly efficiency between the spiral guiding strip 111 and the pressure-bearing cylinder 11 accordingly.

[0055] Generally, only one spiral guiding strip 111 as shown in the figure is required. However, if the material conveying pressure in actual application is relatively large or there are other special working condition operation requirements, and the working conditions permit, two or more spiral guiding strips 111 can also be arranged in the pressure-bearing cylinder 11, and two or more groups of material receiving ports 112 and discharge ports 113 are arranged accordingly to realize the synchronous operation of multiple spherical material lifting and conveying paths. Correspondingly, each spiral guiding strip 111 should extend spirally in the same direction and be arranged in parallel to avoid structural interference between them and affect the smooth lifting and conveying of spherical materials.

[0056] On the other hand, as shown in Figure 3 the driving assembly includes a transmission shaft 14 coaxially inserted into the roller 12 and a motor 141 capable of driving the transmission shaft 14 to rotate about a fixed axis. The transmission shaft 14 and the roller 12 are circumferentially linked. The structure of the transmission shaft 14 is simple and reliable, and the rotation tracking performance during the rotation about a fixed axis is good. The reliable assembly and linkage between the transmission shaft 14 and the roller 12 are realized through key connection or welding to ensure the transmission efficiency and motion synchronization between the transmission shaft 14 and the roller 12. During actual operation, the motor 141 can control the rotation speed, start and stop of the roller 12 so as to be able to pause the spherical material at an appropriate position for corresponding material detection and other operations to meet the working condition requirements of the equipment.

[0057] Furthermore, an upper bearing support 142 is fixedly arranged on the inner wall at the top end of the pressure-bearing cylinder 11, and a lower bearing support 143 is fixedly arranged on the inner wall at the bottom end of the pressure-bearing cylinder 11. The driving assembly further includes a top bearing 144 installed in the middle of the upper bearing support 142 and sleeved on the top end of the transmission shaft 14 in a linked manner and a bottom bearing 145 installed in the middle of the lower bearing support 143 and sleeved on the bottom end of the transmission shaft 14 in a linked manner. Bearings are arranged at the upper and lower ends of the transmission shaft 14 respectively to fully ensure the structural support for the transmission shaft 14, optimize the rotation stability and tracking performance of the transmission shaft 14, and make the rotation about a fixed axis of the transmission shaft 14 and the roller 12 more stable and efficient.

[0058] More specifically, the top of the pressure-bearing cylinder 11 is detachably connected with an upper end plate 116 that is easy to disassemble, and the upper bearing support 142 is arranged on the bottom wall of the upper end plate 116; the bottom of the pressure-bearing cylinder 11 is detachably connected with a lower end plate 117 that is easy to disassemble, and the lower bearing support 143 and the chip guide plate 131 are both arranged on the top wall of the lower end plate 117. If necessary, the upper end plate 116 and / or the lower end plate 117 can be disassembled to inspect, maintain or replace the roller 12 and other components inside the pressure-bearing cylinder 11. After the corresponding operations are completed, the upper end plate 116 and the lower end plate 117 can be installed to the ends of the pressure-bearing cylinder 11 accordingly.

[0059] Accordingly, the motor 141 is disposed on the top wall of the upper end plate 116, and the output shaft of the motor 141 is coaxially linked with the transmission shaft 14. In this way, a coaxial direct drive transmission structure is formed between the motor 141 and the transmission shaft 14, thereby further improving the transmission efficiency between the motor 141 and the transmission shaft 14, thereby making the fixed axis rotation of the roller 12 more stable and smooth, and the corresponding spiral lifting process of the spherical material is also more stable and efficient.

[0060] In addition, key references Figure 2 As shown, a guide plate 118 is provided inside the pressure cylinder 11. The guide plate 118 is located above the top of the roller 12. An appropriate matching gap is left between the guide plate 118 and the top of the roller 12. The two ends of the guide plate 118 are respectively connected to the inner circumferential wall of the pressure cylinder 11, and the middle part of the guide plate 118 is matched with the inner circumferential wall of the pressure cylinder 11. The size of the gap is larger than the outer diameter of a single spherical material to form a discharge trough for the spherical material to pass through, and the discharge trough is connected to the upstream of the discharge port 113 along the conveying direction of the spherical material. Figure 2 As shown, the guide plate 118 can be an arc-shaped plate member with the arc top direction of the cross section opposite to the pressure cylinder 11. After the spherical material moves along the spiral guide strip 111 to the top of the roller 12, the spherical material continues to move upward along the spiral guide strip 111 until the spherical material contacts and abuts against the inner wall of the end of the guide plate 118. At this time, the position of the spherical material can be referred to Figure 2 As shown by the dotted line at the spherical position at A, since the spherical material still has inertia at this time, the spherical material will move along the inner wall of the guide plate 118 toward the other end of the guide plate 118 until it falls into the discharge port 113. At this time, the position of the spherical material can be referred to Figure 2 The spherical position indicated by the dotted line at B in the middle is shown, so that the spherical material leaves the pressure tube 11 through the discharge port 113 to be sent to the downstream station.

[0061] In addition, a discharge guiding groove 15 extending obliquely in the vertical direction is provided on the upper outer peripheral wall of the pressure-bearing cylinder 11. The top end of the discharge guiding groove 15 communicates with the downstream of the discharge port 113 along the conveying direction of the spherical materials. The spherical materials discharged from the pressure-bearing cylinder 11 through the discharge port 113 enter the discharge guiding groove 15 through the top end of the discharge guiding groove 15 communicating with the discharge port 113. Under the guidance of the inclined structure of the discharge guiding groove 15 itself, the spherical materials roll to the bottom end of the discharge guiding groove 15 under the action of their own gravity, and are thus conveyed to the downstream working station through the bottom end of the discharge guiding groove 15.

[0062] Correspondingly, a material receiving guiding groove 16 extending obliquely in the vertical direction is provided on the lower outer peripheral wall of the pressure-bearing cylinder 11. The bottom end of the material receiving guiding groove 16 communicates with the upstream of the material receiving port 112 along the conveying direction of the spherical materials. The spherical materials sent from the upstream working station enter the material receiving guiding groove 16 through the top end of the material receiving guiding groove 16. Under the guidance of the inclined structure of the material receiving guiding groove 16 itself, the spherical materials roll to the bottom end of the material receiving guiding groove 16 under the action of their own gravity, and thus enter the pressure-bearing cylinder 11 through the material receiving port 112 in alignment and communication with the bottom end of the material receiving guiding groove 16.

[0063] Generally, the discharge guiding groove 15 and the material receiving guiding groove 16 can be respectively tubular structure components or grooved plate components with side enclosing structures. In practical applications, the specific structural forms of the discharge guiding groove 15 and the material receiving guiding groove 16 can be flexibly selected and adjusted according to specific working conditions and processing conditions. In principle, as long as they can ensure the adaptation to the spherical materials and meet the actual application requirements of the spherical material lifting equipment, they are acceptable.

[0064] In summary, in the spherical material lifting device provided in the present invention, during its operation and use, after the device is started, the driving component drives the roller to rotate. At this time, each limiting wing plate moves circumferentially along with the rotation of the roller. After the spherical material to be conveyed enters the pressure-bearing cylinder through the material receiving port, it directly rolls into the material guiding groove between the two limiting wing plates that are rotating past the alignment position of the material receiving port at this time, and is reliably supported on the spiral material guiding strip; then, the limiting wing plate behind the spherical material located in the material guiding groove along the rotation direction abuts against the spherical material. Thus, as the roller continues to rotate, the limiting wing plate located behind synchronously pushes the spherical material to move circumferentially along the roller. Therefore, by utilizing the rolling cooperation between the spherical material supported on the spiral material guiding strip and the spiral material guiding strip, the spherical material is gradually lifted along the spiral extension structure of the spiral material guiding strip until the spherical material moves to the discharge port, and the spherical material is sent out of the pressure-bearing cylinder through the discharge port to be conveyed to the downstream station equipment, completing the lifting operation of the spherical material. The spherical material lifting device uses the spiral extension spiral material guiding strip in cooperation with the limiting wing plates that rotate circumferentially along with the roller to push the spherical material along the spiral guiding direction to achieve the stable lifting of the spherical material, greatly optimizing the position lifting effect of the spherical material, improving the lifting and conveying efficiency of the spherical material, and during the conveying process, the spiral material guiding strip, which is the main supporting component of the spherical material, and the spherical material are in rolling cooperation, effectively reducing the structural wear of the spherical material, reducing the number of debris generated by the wear, and further avoiding problems such as blockage or blockage of the conveying space caused by excessive debris, making the lifting and conveying process of the spherical material smoother and more fluent.
