Description
Technical Field
[0001] This utility model relates to the technical field of powder material conveying devices, and in particular to a dust-free continuous conveying device for pre-made thickeners. Background Technology
[0002] In the production process of lubricating grease, the delivery of pre-thickened agents is a key step. These powders are characterized by fine particle size, poor flowability, and easy dust generation.
[0003] In the production and processing of pre-made thickeners, the material conveying process is a key link in ensuring production continuity and the quality of the working environment.
[0004] While existing pre-made thickener conveying devices achieve the conveying of thickener, they suffer from several drawbacks. Firstly, the connections often rely on rigid joints or simple sealing structures, resulting in poor sealing performance and a high risk of dust leakage during material transport. This not only wastes materials but also pollutes the workshop environment and harms the health of operators. Secondly, during transport, especially at equipment connections and hopper discharge points, the thickener's viscosity and agglomeration properties easily lead to arching and blockages, causing transport interruptions and impacting production efficiency. Furthermore, traditional conveying equipment suffers from poor continuity; some devices employ intermittent feeding, making stable and continuous material transport difficult. The adaptability between the conveying volume and equipment parameters is also insufficient, often resulting in material accumulation or insufficient conveying volume. In addition, existing devices lack ease of maintenance; the disassembly and assembly of connections are complex, and repairs are time-consuming when blockages or seal failures occur, further affecting production progress. These problems severely restrict the efficiency, environmental friendliness, and stability of pre-made thickener production. Therefore, a dust-free continuous conveying device for pre-made thickeners is proposed to address these issues. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a dust-free continuous conveying device for pre-made thickener, comprising a mobile silo 1, a drying device 4, and a crushing device 5. The mobile silo 1 serves as an intermediate storage and transfer link. A vibrating unloading device 6 is fixedly connected to the outer wall of the mobile silo 1. The function of the vibrating unloading device 6 is to prevent material from arching and clogging in the silo through vibration, ensuring smooth unloading. Specifically, the vibrating unloading device 6 is an electromagnetic vibrator with a vibration frequency of 50-60Hz. This frequency range has been experimentally verified to effectively adapt to the physical characteristics of the thickener, avoiding excessive crushing of the material due to excessively high vibration frequency or unsmooth unloading due to excessively low vibration frequency. The bottom conical section installed on the outer wall of the mobile silo 1 has a structural design that facilitates material accumulation towards the discharge port. Combined with the vibrating device, it can further improve the unloading efficiency. The inlet of the mobile silo 1 and the discharge port of the drying device 4 are connected. A first enclosed feeding screw conveyor 2 is fixedly connected, which is responsible for conveying the dried material to the mobile hopper 1. A second enclosed feeding screw conveyor 3 is fixedly connected between the discharge port of the mobile hopper 1 and the feed port of the crushing equipment 5. The second enclosed feeding screw conveyor 3 is responsible for conveying the material in the mobile hopper 1 to the crushing equipment 5 for further processing. The casings of both the first enclosed feeding screw conveyor 2 and the second enclosed feeding screw conveyor 3 are fully enclosed structures. The fully enclosed structure is one of the core designs for achieving dust-free conveying, which can effectively prevent material dust from leaking out. The built-in conveying screw pushes the material forward by rotating, realizing continuous conveying. The screw diameter is matched with the conveying capacity. The screw diameter is matched according to the preset conveying capacity to ensure stable conveying process and prevent material accumulation or insufficient conveying.
[0033] Reference Figure 1 , Figure 3 and Figure 4Sealing connection components 7 are installed at the connection points between the mobile hopper 1, drying equipment 4, crushing equipment 5 and the first enclosed feeding screw conveyor 2 and the second enclosed feeding screw conveyor 3. Sealing connection components 7 are key components ensuring the sealing of the entire conveying system, preventing dust leakage at equipment connection points. Sealing connection components 7 include a connecting hose 71, which has a certain degree of flexibility to adapt to slight displacement that may occur during equipment operation, and also serves to connect adjacent equipment. A first snap-fit member 72 is fixedly connected to the upper edge of the outer wall of the connecting hose 71, which is used to snap and fix it to the upper connecting bracket 75. A second snap-fit member 73 is fixedly connected to the lower edge of the outer wall of the connecting hose 71. For securing the connection to the lower connecting bracket 75, two first locking members 72 and two second locking members 73 are provided. The two locking members ensure a more stable connection, preventing the connecting hose 71 from deflecting or detaching during material transport. Both the first locking members 72 and the second locking members 73 are mirror images of the connecting hose 71 along its central axis. This mirror image arrangement ensures even force distribution and further improves connection stability. A locking bolt assembly 74 is threaded between the second locking member 73 and the first locking member 72. The locking bolt assembly 74 locks the first locking member 72 and the second locking member 73, enhancing the tightness of the connection. The locking bolt assembly 74 includes a long bolt and a locking nut. The long bolt passes through the locking member, and the locking nut is tightened by threads. To ensure a stable connection, both ends of the connecting hose 71 are movably engaged with connecting brackets 75. The connecting brackets 75 serve as transition components between the connecting hose 71 and the equipment port, achieving a connection that combines flexibility and rigidity. There are four sets of connecting brackets 75, with two brackets in each set. Two of the connecting brackets 75 are mirror images of each other along the central axis of the connecting hose 71. The top of one connecting bracket 75 in the first set is fixedly connected to the discharge port of the drying equipment 4, and the bottom of the other connecting bracket 75 in the first set is fixedly connected to the input end of the first enclosed feeding screw conveyor 2. This clearly defines the specific connection positions of the first set of connecting brackets 75, achieving a sealed connection between the drying equipment 4 and the first enclosed feeding screw conveyor 2. The top of one connecting bracket 75 in the second set is fixedly connected to... A first set of connecting brackets 75 is fixedly connected to the output end of the first enclosed feeding screw conveyor 2, and the bottom end of another connecting bracket 75 of the second set is fixedly connected to the inlet of the mobile hopper 1, thus clarifying the connection position of the second set of connecting brackets 75 and achieving a sealed connection between the first enclosed feeding screw conveyor 2 and the mobile hopper 1. A third set of connecting brackets 75 is fixedly connected to the discharge port of the mobile hopper 1 at its top, and the bottom end of another connecting bracket 75 of the third set is fixedly connected to the input end of the second enclosed feeding screw conveyor 3, thus clarifying the connection position of the third set of connecting brackets 75 and achieving a sealed connection between the mobile hopper 1 and the second enclosed feeding screw conveyor 3. A fourth set of connecting brackets 75 is fixedly connected to the output end of the second enclosed feeding screw conveyor 3 at its top.Furthermore, the bottom end of another connecting bracket 75 in the fourth group is fixedly connected to the feed inlet of the crushing equipment 5, clearly defining the connection position of the fourth group connecting bracket 75 and realizing the sealed connection from the second closed-type feeding screw conveyor 3 to the crushing equipment 5. The outer surface of the connecting bracket 75 is provided with a snap-fit groove 76, which is a structure that cooperates with the first snap-fit member 72 and the second snap-fit member 73 to achieve snap-fit. The snap-fit groove 76 has an L-shaped groove structure, which facilitates the insertion of the snap-fit member first and then rotation to lock it, realizing quick installation and stable connection. There are two snap-fit grooves 76, and the two snap-fit grooves 76 correspond to... Two snap-fit components ensure symmetry and stability of the snap-fit connection. Two snap-fit slots 76 are mirror-image positioned along the central axis of the connecting base 75, matching the mirror image of the snap-fit components to ensure a smooth and secure snap-fit process. The outer walls of the first snap-fit component 72 and the second snap-fit component 73 are movably snapped into the inner side of the snap-fit slots 76. Through the cooperation of the two snap-fit components and the snap-fit slots 76, a detachable connection between the connecting hose 71 and the connecting base 75 is achieved, facilitating future maintenance and replacement. A rotating bracket 77 is fixedly connected to the inner wall of the connecting base 75, providing mounting space for the anti-clogging impeller 78. The rotating support structure includes a rotating base 77 with an anti-clogging impeller 78 movably engaged on its inner side. The anti-clogging impeller 78 rotates with the material flow, serving to agitate the material and prevent material buildup and blockage at the connection point. A first permanent magnet 79 is fixedly connected to the inner wall of the rotating base 77. The first permanent magnet 79 and a second permanent magnet 710 work together to generate magnetic force, providing auxiliary power and positioning for the rotation of the anti-clogging impeller 78. Second permanent magnets 710 are fixedly connected to the outer wall of the anti-clogging impeller 78. The magnetic poles of the second permanent magnet 710 interact with those of the first permanent magnet 79, driving the anti-clogging impeller 78 to rotate more... The impeller rotates smoothly. Multiple first permanent magnets 79 and second permanent magnets 710 are arranged in a ring. This ring distribution ensures that the magnetic force is evenly applied to the anti-clogging impeller 78, guaranteeing stable rotation. Each pair of first permanent magnets 79 and second permanent magnets 710 is arranged in a one-to-one correspondence, ensuring a stable magnetic force. Furthermore, adjacent sides of the first permanent magnets 79 and second permanent magnets 710 share the same magnetic poles. The repulsive property of like poles generates a continuous driving force, assisting the anti-clogging impeller 78 in rotating synchronously with the material flow, thus enhancing the anti-clogging effect.
[0034] Working Principle: The working principle of this pre-made thickener dust-free continuous conveying device is as follows: The thickener material processed by the drying equipment 4 enters the first closed-loop feeding screw conveyor 2 through its discharge port via the first set of sealing connection components 7. At the same time, the connecting hose 71 is engaged with the L-shaped locking groove 76 of the corresponding connecting seat 75 through the first locking member 72 and the second locking member 73, and is tightened by the locking bolt assembly 74, realizing the sealed connection between the drying equipment 4 and the first closed-loop feeding screw conveyor 2. Meanwhile, the anti-clogging impeller 78 in the connecting seat 75 rotates under the action of the material flow thrust and the continuous pushing force of the first permanent magnet 79 and the second permanent magnet 710, which repel each other, preventing the material from accumulating and clogging at the connection point. The first closed-loop feeding screw conveyor 2, with its built-in conveying screw and the rotation of the screw diameter adapted to the conveying capacity, continuously conveys the material within the fully enclosed casing. The material is continuously conveyed to the inlet of the mobile silo 1. This process is sealed by the second set of sealing connection components 7 to prevent dust leakage. After the material enters the mobile silo 1 for temporary storage, the vibrating unloading device 6 installed on its bottom conical section uses a 50-60Hz electromagnetic vibrator to prevent material bridging through vibration. Combined with the conical structure, it promotes the material to gather towards the unloading port. Subsequently, the material enters the second closed feeding screw conveyor 3 through the third set of sealing connection components 7. It is continuously pushed by the conveying screw in its fully enclosed casing. Finally, it is sent to the crushing equipment 5 for subsequent processing through the fourth set of sealing connection components 7. Throughout the process, the sealing connection components 7 of all connection parts are adapted to slight displacement of the equipment through flexible connection, and the anti-clogging impeller 78 driven by permanent magnets ensures smooth material flow. Combined with the fully enclosed design of the closed screw conveyor, the dust-free continuous conveying of the thickener is achieved.
[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
