Description

Technical Field

[0001] This utility model relates to the technical field of powder material conveying equipment, specifically to a powder granule material suction device. Background Technology

[0002] Sodium-ion batteries, as a new generation of energy storage technology, exhibit significant advantages over lithium-ion and lead-acid batteries in terms of safety, cycle life, and energy density. Their core component, the ceramic cell, is typically made from high-purity special alumina granulated powder, requiring extremely stringent standards for the purity and consistency of the raw materials.

[0003] The production of alumina granulation powder generates a considerable amount of recycled material. Currently, the reuse of this recycled powder is generally done manually: operators must hold a suction pipe and use negative pressure to suck and feed the material from the packaging container. This operating mode has many drawbacks: firstly, holding a heavy suction pipe is labor-intensive and inefficient; secondly, relying solely on manual operation makes the suction pipe prone to shaking, causing material spillage during transfer, resulting in both waste and environmental pollution. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a powder and granular material suction device. By introducing a sliding balance mechanism, it effectively solves the problems of high labor intensity, unstable operation, low efficiency and easy spillage when manually holding the tube to suction material.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a powder / granular material suction device, comprising: a suction pipe, the inlet end of which is used to extend into a material packaging barrel for suction; a conveying pipe, the first end of which is connected to the outlet end of the suction pipe via a flexible hose; a negative pressure source, connected to the second end of the conveying pipe, for providing power for suction; and a sliding balancing mechanism, the sliding balancing mechanism comprising a slide rail, a balancer connected to the slide rail, and a connecting assembly, one end of which is connected to the balancer, and the other end of which is connected to the suction pipe or the flexible hose, the balancer providing a balancing pull to the flexible hose and the suction pipe through the connecting assembly.

[0006] The slide rail is mounted on a first support frame, which is a portal frame spanning the conveying pipeline. The slide rail is fixed to the crossbeam of the portal frame by a mounting rod.

[0007] The connecting component is a steel wire rope.

[0008] The feed end of the suction pipe is provided with a horn-shaped suction cup-shaped opening, and an anti-clogging mesh is provided between the horn-shaped suction cup-shaped opening and the suction pipe.

[0009] The outer edge of the horn-shaped suction cup nozzle is fitted with a flexible protective collar, the outer diameter of which is smaller than the inner diameter of the packaging barrel.

[0010] The negative pressure source is a Roots blower.

[0011] The conveying pipeline includes a first conveying pipe and a second conveying pipe; one end of the first conveying pipe is connected to the suction pipe through the flexible hose, and the other end is connected to a dust collector; the second conveying pipe is connected between the dust collector and the negative pressure source.

[0012] The dust collector's outlet is connected in sequence to a temporary storage tank and a premixing tank.

[0013] The first conveying pipe, the second conveying pipe, and the suction pipe are stainless steel pipes, and the hose is a steel wire reinforced hose.

[0014] The first delivery pipe is equipped with a transparent viewing window and a blockage removal port.

[0015] In the vertical direction, the suction pipe is at the lowest operating position, the dust collector is installed at a higher position than the suction pipe, and the negative pressure source is installed at the highest position.

[0016] As can be seen from the above solutions, the advantages of this utility model are:

[0017] The continuous balancing force provided by the sliding balancing mechanism completely solves the core problems of heavy and laborious manual pipe holding, unstable operation, and easy spillage. Operators only need to apply a small amount of force to guide the suction pipe, which greatly reduces labor intensity and improves operation stability and suction efficiency.

[0018] By mounting the slide rail on the first support frame (especially the gantry bracket spanning the pipeline), the suction pipe can move freely along the slide rail, easily covering packaging barrels in different locations, greatly enhancing the equipment's adaptability to different operating scenarios and overcoming the limitations of fixed installation.

[0019] By setting a funnel-shaped suction cup-shaped inlet and an anti-clogging net at the feed end of the suction pipe, the material can be preliminarily screened while being sucked up, effectively intercepting lumps and impurities, preventing pipe blockage from the source and ensuring the uniformity of the slurry in subsequent processes, thus avoiding agglomeration problems caused by clumping.

[0020] The system utilizes a Roots blower as the negative pressure source, providing strong and stable power. All conveying pipes and suction pipes are made of wear-resistant materials such as stainless steel, combined with steel wire-reinforced flexible hoses, forming a robust and durable closed conveying system. Integrating a dust collector, temporary storage tank, and premixing tank, the system achieves fully automated and closed-loop operation of the powder process from recovery to batching, not only eliminating dust hazards but also ensuring the accuracy and consistency of material proportions in mass production.

[0053] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments to further understand the purpose, solution and effect of this utility model, but it is not intended to limit the scope of protection of the appended claims of this utility model.

[0054] References to "embodiment," "another embodiment," "this embodiment," etc., in the specification refer to embodiments that may include specific features, structures, or characteristics, but not every embodiment must include these specific features, structures, or characteristics. Furthermore, such expressions do not refer to the same embodiment. Moreover, when describing specific features, structures, or characteristics in conjunction with embodiments, whether or not explicitly described, it is indicated that incorporating such features, structures, or characteristics into other embodiments is within the knowledge of those skilled in the art.

[0055] It should be noted that in the description of this utility model, the terms "upper", "lower", "front", "rear", "top", "bottom" and "approximately" indicate the orientation or positional relationship or parameters based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, a specific size, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0056] like Figures 1 to 3 As shown, an embodiment of the present invention provides a powder and granular material suction device, including a negative pressure source 10, a conveying pipe 11, a dust collector 12, a temporary storage tank 13, a premixing tank 14, a sliding balance mechanism 15, a suction pipe 16, and a flexible hose 17.

[0057] The negative pressure source 10, for example a Roots blower, is installed on the second support frame 100, providing stable and powerful power for the entire material suction process. The high negative pressure characteristics of the Roots blower can effectively overcome the resistance of powder being lifted over long distances in the pipeline.

[0058] The conveying pipeline 11 includes a first conveying pipe 110 and a second conveying pipe 111. One end 1100 of the first conveying pipe 110 (i.e., the first end of the conveying pipeline 11) is connected to the discharge end 161 of the suction pipe 16 via a flexible hose 17, and the other end is connected to the dust collector 12. One end of the second conveying pipe 111 is connected to the exhaust port of the dust collector 12, and the other end 1110 (i.e., the second end of the conveying pipeline 11) is connected to the negative pressure source 10. The discharge port of the dust collector 12 is sequentially connected to a temporary storage tank 13 and a premixing tank 14. Thus, the flow paths of materials and airflow are clearly distinguished: the airflow carrying powder particles enters from the suction pipe 16, flows sequentially through the flexible hose 17 and the first conveying pipe 110, and achieves gas-solid separation within the dust collector 12; the separated powder particles fall into the discharge port at the bottom of the dust collector 12 and sequentially enter the temporary storage tank 13 and the premixing tank 14 for subsequent processes; while the purified air is discharged via the second conveying pipe 111 and finally by the negative pressure source 10. This design constitutes a complete, closed-loop processing system from material recovery, purification, temporary storage to final premixing.

[0059] To achieve material conveying from low to high and optimize spatial layout, the first conveying pipe 110 can adopt a Z-shaped bend to smoothly lift the material; the second conveying pipe 111 can adopt a Z-shaped bend to cross the equipment space and guide the purified air to the negative pressure source 10 at a higher position. This specific pipe shape design ensures smooth airflow and reduces the risk of blockage.

[0060] Furthermore, the first conveying pipe 110, the second conveying pipe 111, and the suction pipe 16 can all be made of stainless steel, ensuring the wear resistance and structural strength of the conveying channel. Meanwhile, the connecting hose 17 can be a steel wire reinforced hose, ensuring both flexible connection and resistance to negative pressure and tensile strength. These material choices collectively constitute a robust and durable closed conveying system capable of meeting the stringent operating conditions required in the recovery of powder and granular materials, effectively extending the equipment's service life.

[0061] Furthermore, to improve the reliability and maintainability of the equipment, observation and unblocking functions can be integrated into the first delivery pipe 110. Specifically, for example... Figure 1 As shown, a transparent window 1101 made of a high-strength transparent material (such as polycarbonate) is embedded in the straight pipe section in the middle. The transparent window 1101 can be sealed to the stainless steel pipe of the first conveying pipe 110 through quick-release clamps (not shown) at both ends to form a visible pipe section for direct observation of the flow state of the powder material in the pipe, so as to facilitate timely detection of conveying abnormalities.

[0062] At the same time, such as Figure 2As shown, a clearing port 1102 is provided at the lowest point of the Z-shaped bend in the first delivery pipe 110. This clearing port 1102 can be, for example, composed of a flanged short pipe welded to the outer wall of the pipe, a matching flange cover, and quick-release bolts for tightening the flange cover, with a sealing ring between the flange mating surfaces. This design allows operators to quickly open the clearing port 1102 for unblocking when a blockage occurs, achieving rapid local maintenance of the pipeline without disassembling the entire pipe section, greatly reducing maintenance time and labor intensity.

[0063] like Figure 1 and Figure 2 As shown, the feed end 160 of the suction tube 16 is used to extend into the material packaging barrel 2 for suction. The feed end 160 is provided with a funnel-shaped suction cup nozzle 162, the diameter of which is designed to be smaller than the inner diameter of the packaging barrel 2. When it is placed into the packaging barrel 2 for suction, the structural features can be used to stably adhere the inner film bag to the barrel wall, effectively solving the problem that the traditional straight tube nozzle is prone to sucking up the inner film bag due to negative pressure.

[0064] like Figure 3 As shown, an anti-clogging mesh 163 is provided between the horn-shaped suction cup nozzle 162 and the suction pipe 16, which effectively blocks large particles or lumps in different types of recycled materials from entering the suction pipe 16, filters out lumps, and makes the particle size of the materials uniform during the mixing process, so that they can be melted and mixed more fully and avoid the problem of incomplete mixing due to clumping.

[0065] Furthermore, a protective collar 164 made of a flexible material (such as rubber or polyurethane) is fitted around the outer edge of the horn-shaped suction cup nozzle 162. The outer diameter of the protective collar 164 is slightly smaller than the inner diameter of the packaging drum 2.

[0066] The addition of the protective collar 164 brings multiple benefits: First, its flexibility effectively buffers the contact or collision between the horn-shaped suction nozzle 162 and the inner wall of the packaging barrel 2, preventing impact noise or scratches between the metal nozzle and the packaging barrel 2 (especially the metal barrel), thus protecting the equipment and the packaging. Second, when the suction pipe 16 is inserted into the packaging barrel 2, the protective collar 164 automatically centers and guides the nozzle to the center of the barrel, preventing it from sticking to the barrel wall or inner film bag and causing poor suction. Finally, the fit between the protective collar 164 and the barrel wall of the packaging barrel 2 also creates a relatively sealed space around the suction port of the suction pipe 16, which helps to further suppress the spread of dust during operation.

[0067] like Figures 1 to 3As shown, the sliding balancing mechanism 15 includes a slide rail 150, a balancer 151, and a connecting assembly 152. The slide rail 150 is mounted on a first support frame 153, which is a portal frame spanning the conveying pipe 11. The slide rail 150 is fixed to the crossbeam 1530 of the portal frame via a mounting rod 154. Furthermore, the sliding balancing mechanism 15 also includes a T-shaped slider 155, which is placed within the matching slide rail 150. The slider 155 is connected to the balancer 151 and can drive the balancer 151 to move smoothly along the slide rail 150. One end of the connecting assembly 152 is connected to the balancer 151, and the other end is connected to the suction pipe 16 or the hose 17. The balancer 151 provides balancing tension to the hose 17 and the suction pipe 16 through the connecting assembly 152. In this embodiment, the other end of the connecting assembly 152 is connected to the section of the hose 17 near the suction pipe 16.

[0068] To ensure the safety and reliability of the sliding balance mechanism 15, limit blocks (not shown) can be provided at both ends of the slide rail 150. The limit blocks are preferably made of metal or high-strength nylon and are installed on the end face of the slide rail 150 by bolt fastening or welding.

[0069] The function of this limiting block is to effectively block the balancer 151 and its connected slider 155 when they slide to the end of their stroke on the slide rail 150, thereby preventing them from accidentally detaching from the slide rail 150. This structure not only protects the balancer 151 and other components from damage due to collisions and falls, but also eliminates potential safety hazards caused by components falling off in the workshop environment, ensuring smooth operation and personnel safety.

[0070] The core of the sliding balancing mechanism 15 provided in this embodiment lies in assisting manual operation with mechanical balancing force, achieving the goals of labor saving, stability, and flexibility. Specifically, the balancer 151 provides a continuous upward balancing force to the suction pipe 16 and the connected hose 17 through the connecting component 152 (e.g., a steel wire rope). This force precisely offsets most of the self-weight of the suction pipe 16 and the hose 17. When the operator needs to perform suction operations, there is no need to exert effort to bear the weight; they only need to gently guide the suction pipe 16 by hand. During lateral movement, the operator can drive the balancer 151 to slide along the slide rail 150, thereby easily transferring the suction pipe 16 from one workstation to another. Throughout the process, the suction pipe 16 remains in a stable "weightless" state, effectively avoiding shaking and material spillage caused by unstable hand handling, and greatly reducing the operator's labor intensity.

[0071] Furthermore, such as Figure 1As shown, along the vertical direction, the suction pipe 16 is at the lowest operating position, the dust collector 12 is installed higher than the suction pipe 16, and the negative pressure source 10 is installed at the highest position. This specific spatial layout utilizes the synergistic effect of the material's own weight and negative pressure suction to ensure that powder particles can smoothly and efficiently complete the entire closed-loop flow from low-level recovery, mid-level dust removal to final treatment in the system.

[0072] The embodiments of the present invention have been described above with reference to the accompanying drawings. However, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present invention without departing from the spirit and scope of the claims, and all of these forms fall within the protection scope of the present invention.
