Description

Technical Field

[0001] This utility model relates to the field of screw conveyor technology, specifically to a conveying mechanism with a quickly replaceable screw for processing highly active magnesium oxide. Background Technology

[0002] Screw conveyors are core material transport devices connecting different process equipment. In experimental equipment used to process highly reactive magnesium oxide, the different properties of the raw materials (such as wet materials after flotation or powdery materials after drying) necessitate the selection of different types of screw structures. Generally, slurry-like materials have high viscosity and tend to generate significant resistance as they are conveyed, requiring the use of shaftless screw conveyors; while powdery or granular materials have low resistance and are conveyed using shafted screw conveyors.

[0003] Currently, screw conveyors designed for different material properties are typically independent equipment. Therefore, in experimental research on "processing highly active magnesium oxide," both shaftless and shafted screw conveyors need to be purchased simultaneously, consuming significant budget and experimental space. Under experimental conditions, researchers often need to verify multiple raw material forms (such as magnesium oxide with different moisture contents) or process parameters (such as a comparison between drying and wet conveying) within the same equipment set. This places higher demands on the rapid adjustability of the conveying equipment. Utility Model Content

[0004] Therefore, this utility model provides a conveying mechanism for processing highly active magnesium oxide with a quickly replaceable spiral body. Without significantly altering the main structure, the mechanism achieves rapid switching of spiral body types through modular design or detachable connection.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A conveying mechanism for processing highly reactive magnesium oxide with a quickly replaceable auger includes a feeding cylinder, a auger rotatably disposed within the feeding cylinder, and a coupling sleeve connecting a power mechanism and the auger. The auger has a auger flange at its rear end, and the coupling sleeve has a coupling sleeve flange located within the rear end of the feeding cylinder. The coupling sleeve flange is detachably connected to the auger flange. A connecting sleeve is provided at the rear end of the coupling sleeve, and the connecting sleeve is fixed to the power shaft of the power mechanism.

[0007] Furthermore, a fixing plate is welded to the rear end of the feeding cylinder. The fixing plate is welded to the front side of the fixing bracket. The fixing plate and the fixing bracket are provided with through holes for the connecting sleeve to pass through. One end of the connecting sleeve passes through the through holes of the fixing plate and the fixing bracket and is sleeved and installed on the power shaft. The outer peripheral surface of the connecting sleeve does not contact the through hole wall of the fixing plate. The outer peripheral surface of the connecting sleeve is sealed to the through hole wall of the fixing bracket by a sealing element.

[0008] Furthermore, the inner wall of the connecting sleeve is provided with a connecting sleeve keyway extending in the front-rear direction, the power shaft is provided with an oblong power keyway, the connecting sleeve is sleeved on the power shaft of the power mechanism, the connecting sleeve keyway is aligned with the power keyway and a key block is installed between the two; the front end of the connecting sleeve is provided with an enlarged groove, a retaining ring is installed in the enlarged groove, the front end of the power shaft is provided with a threaded hole, the middle of the retaining ring is provided with a through hole, and the retaining ring is connected to the power shaft by bolts.

[0009] Furthermore, a hopper is provided at the upper rear end of the feeding cylinder.

[0010] Furthermore, the front end of the coupling sleeve flange is provided with an annular stop, and the rear end of the spiral flange is provided with an annular groove, the annular groove being fastened to the annular stop; the coupling sleeve flange is provided with multiple threaded holes, the spiral flange is provided with multiple through holes, and the coupling sleeve flange and the spiral flange are detachably connected by bolts.

[0011] Furthermore, the helical body is divided into an axial helical body and an axialless helical body.

[0012] Furthermore, the power mechanism includes an electric motor and a reducer that is driven by the electric motor, and the output shaft of the reducer is a power shaft that is connected to the coupling sleeve.

[0013] Furthermore, an auxiliary support is welded and fixed to the lower middle part of the feeding cylinder, and the auxiliary support, the fixed support, and the power mechanism are fixed on the same workbench.

[0014] Furthermore, the front end of the feeding cylinder is an open end.

[0015] Furthermore, a process connection flange is provided on the outer front end of the feeding cylinder.

[0016] The present invention has the following advantages:

[0017] With the detachable connection between the spiral flange and the coupling sleeve flange, there is no need to replace the main components such as the feeding cylinder and power mechanism. Different types of spirals can be replaced simply by disassembling the connecting parts between the two flanges, which greatly reduces the equipment purchase cost and experimental space occupation, and enables rapid switching of spiral types.

Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] like Figure 1-4 As shown, this embodiment provides a conveying mechanism with a quickly replaceable auger for processing highly active magnesium oxide, including a feeding cylinder 1, an auger 2 rotatably disposed within the feeding cylinder 1, and a coupling sleeve 3 connecting a power mechanism and the auger 2; the rear end of the auger 2 is provided with an auger flange 21, the front end of the coupling sleeve 3 is located within the rear end of the feeding cylinder 1 and is provided with a coupling sleeve flange 31, the coupling sleeve flange 31 and the auger flange 21 are detachably connected, and the rear end of the coupling sleeve 3 is provided with a connecting sleeve 32, which is fixed to the power shaft 51 of the power mechanism. Exemplarily, the coupling sleeve flange 31 and the connecting sleeve 32 are integrally formed; the auger flange 21 is welded and fixed to the auger 2.

[0028] The conveying mechanism for processing highly active magnesium oxide provided in this embodiment, which allows for rapid replacement of the spiral, precisely addresses the core needs in the background technology, namely, the need to purchase both shaftless and shafted spiral conveyors, thus occupying budget and space, and the technical problem of "achieving rapid switching of the spiral 2 without significantly altering the main structure." Specifically, through the detachable connection between the spiral flange 21 and the coupling sleeve flange 31, it is possible to replace different types of spirals 2 without replacing the main components such as the feeding cylinder 1 and the power mechanism. This significantly reduces equipment purchase costs and experimental space occupation, enabling rapid switching of the spiral 2 type and meeting the requirement of "rapid adjustability" in experiments to verify various raw material forms or process parameters.

[0029] In one embodiment, a fixing plate 11 is welded to the rear end of the feeding cylinder 1. The fixing plate 11 is welded to the front side of the fixing bracket 12. The fixing plate 11 and the fixing bracket 12 are provided with through holes for the connecting sleeve 32 to pass through. One end of the connecting sleeve 32 passes through the through holes of the fixing plate 11 and the fixing bracket 12 and is sleeved and installed on the power shaft 51. The outer peripheral surface of the connecting sleeve 32 does not contact the through hole wall of the fixing plate 11. The outer peripheral surface of the connecting sleeve 32 is sealed to the through hole wall of the fixing bracket 12 by the sealing element 13.

[0030] The feeding cylinder 1 is welded to the front of the fixed bracket 12 via a rear fixing plate 11, effectively fixing the position of the feeding cylinder 1 and preventing it from shifting during the operation of the screw 2, thus ensuring conveying stability. The connecting sleeve 32 does not contact the fixing plate 11, preventing friction between the connecting sleeve 32 and the fixing plate 11 during rotation, reducing component wear, and extending the service life of the equipment. The connecting sleeve 32 and the fixed bracket 12 are sealed by a sealing element 13, effectively preventing dust or material particles generated during conveying from leaking through the gap between the connecting sleeve 32 and the bracket, maintaining a clean experimental environment, and avoiding material waste.

[0031] In one embodiment, the inner wall of the connecting sleeve 32 is provided with a connecting sleeve keyway 33 extending in the front-rear direction, and the power shaft 51 is provided with an oblong power keyway 52. ​​The connecting sleeve 32 is sleeved on the power shaft 51 of the power mechanism. The connecting sleeve keyway 33 is aligned with the power keyway 52 and a key block (not shown in the figure) is installed between them. The front end of the connecting sleeve 32 is provided with an enlarged hole groove 34, and a retaining ring 36 is installed in the enlarged hole groove 34. The front end of the power shaft 51 is provided with a threaded hole, and the middle of the retaining ring 36 is provided with a through hole. The retaining ring 36 is connected to the power shaft 51 by bolts.

[0032] The keyway 33 of the connecting sleeve and the keyway 52 work together to stably transmit power, ensuring that the spiral body 2 rotates synchronously with the power shaft 51. The retaining ring 36 in the enlarged groove 34 is connected to the threaded hole of the power shaft 51 by bolts, which can effectively prevent relative movement between the connecting sleeve 32 and the power shaft 51 in the axial direction, improve the reliability of the connection between the two, and avoid interruption of power transmission.

[0033] In one embodiment, a hopper 14 is provided at the upper rear end of the feeding cylinder 1.

[0034] A hopper 14 is provided at the upper rear end of the feeding cylinder 1, which allows materials to be added directly and conveniently into the feeding cylinder 1. At the same time, the position design of the hopper 14 facilitates the disassembly of the connecting parts between the spiral flange 21 and the coupling sleeve flange 31.

[0035] In one embodiment, the front end of the coupling sleeve flange 31 is provided with an annular stop 35, and the rear end of the spiral flange 21 is provided with an annular groove 22, which is fastened to the annular stop 35; the coupling sleeve flange 31 is provided with multiple threaded holes, and the spiral flange 21 is provided with multiple through holes; the coupling sleeve flange 31 and the spiral flange 21 are detachably connected by bolts.

[0036] The annular stop 35 of the coupling sleeve flange 31 engages with the annular groove 22 of the spiral flange 21, allowing for quick positioning of the relative positions of the two flanges during assembly. This ensures the coaxiality of the spiral 2 and the coupling sleeve 3, reduces assembly errors, and improves power transmission efficiency. The engagement structure of the stop and groove, combined with bolt connections, enhances the sealing of the flange connection, preventing material leakage from the feed cylinder 1 through the flange gap. Furthermore, the use of bolts as connectors, leveraging their excellent disassembly capability, further simplifies the disassembly and assembly steps of the spiral 2, improving replacement efficiency.

[0037] In one embodiment, the helix 2 is divided into a shafted helix and a shaftless helix.

[0038] The spiral body 2 includes two types: shafted spiral body and shaftless spiral body, which can be specifically adapted to materials with different properties in the background technology: the shaftless spiral body can meet the conveying of viscous slurry materials, while the shafted spiral body can meet the conveying of powdery or granular materials with low resistance, directly matching the needs of "multiple raw material form verification" in the experiment and improving the equipment's adaptability to different materials.

[0039] In one embodiment, the power mechanism includes an electric motor 4 and a reducer 5 that is drivenly connected to the electric motor 4, wherein the output shaft of the reducer 5 is a power shaft 51 connected to the coupling sleeve 3.

[0040] The electric motor 4 provides a stable power source for the equipment, and the reducer 5 can adjust the output speed so that the speed of the power shaft 51 is matched with the working load of the screw 2, avoiding material conveying blockage or equipment overload due to improper speed, and ensuring stable and efficient conveying process.

[0041] In one embodiment, an auxiliary support 15 is welded and fixed to the lower middle part of the feeding cylinder 1, and the auxiliary support 15, the fixed support 12, and the power mechanism are fixed on the same workbench.

[0042] The auxiliary support 15 supports the middle of the feeding cylinder 1, which can alleviate the sagging deformation of the middle of the feeding cylinder 1 caused by its own weight and the weight of the material, ensure the straightness of the feeding cylinder 1, and avoid friction between the spiral body 2 and the inner wall of the cylinder. The auxiliary support 15, the fixed support 12, and the power mechanism are fixed on the same workbench, which can ensure the relative position of each core component of the equipment is fixed, reduce vibration during operation, improve the overall structural stability, and facilitate the overall movement or position adjustment of the equipment.

[0043] In one embodiment, the front end of the feeding cylinder 1 is an open end.

[0044] The front end of the feeding cylinder 1 is set as an open end, which allows the material conveyed to the front end by the screw 2 to be discharged directly. The structure is simple and the discharge is smooth. At the same time, the open design makes it convenient to take out and put in the screw 2.

[0045] In one embodiment, a process connection flange 16 is provided on the outer side of the front end of the feeding cylinder 1.

[0046] The process connection flange 16 on the outer side of the front end of the feeding cylinder 1 can be quickly connected to the equipment of the subsequent process without the need to make additional adapter connectors; at the same time, the flange connection can ensure the sealing and coaxiality of the docking point, prevent material leakage during the transfer process, improve the compatibility of the equipment with other equipment in the experimental process, and facilitate the rapid adjustment of the experimental process.

[0047] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
