DETAILED DESCRIPTION

[0040] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the specific implementation methods of the utility model will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

[0041] In order to simplify the drawings, only the parts related to the utility model are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically shown, or only one of them is marked. In this article, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0042] In this article, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" 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 mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0043] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0044] Reference Figure 1 to Figure 6 , which is an embodiment of the utility model, proposes a multifunctional impeller, including: an impeller 1, having a plurality of accommodating grooves 101; a plurality of clamps 3, each of which is provided with a clamp 3; a plurality of blades 2, each of which has a fixing portion 201, and the fixing portion 201 is detachably arranged on the clamp 3; the clamp 3 includes: a clamping claw 303, having a slot 304, and the fixing portion 201 is detachably arranged in the slot 304; an adjusting member, having an extrusion end 315, the extrusion end 315 is rotatably arranged in the slot 304, the extrusion end 315 abuts against the fixing portion 201, and the extrusion end 315 is used to press the fixing portion 201.

[0045] In the above scheme, the problem that the traditional stirring impeller 1 is not adjustable, inconvenient to replace, and the split structure is not firmly fixed is solved. The main body of the impeller 1 of this embodiment is cast or forged with high-strength corrosion-resistant materials, and the surface is precisely processed to ensure smoothness and strength. Several receiving grooves 101 are evenly distributed around the impeller 1, and each receiving groove 101 is used to install the clamp 3, while ensuring the accuracy of the installation position of the blade 2. A clamp 3 is installed in each receiving groove 101, and the clamp 3 is made of high-strength engineering plastics or metal materials to ensure sufficient strength and reduce wear. The core of the clamp 3 is the internally designed card slot 304, the shape of which is precisely matched with the fixed part 201 of the blade 2, which can ensure the correct installation direction and position of the blade 2. The blade 2 adopts a design of variable thickness, length, width and inclination angle to meet different stirring requirements. The fixed part 201 of the blade 2 is designed with a structure matching the card slot 304 of the clamp 3, and can be installed in place by a simple insertion operation. The material of the blade 2 is a wear-resistant and corrosion-resistant alloy material to ensure stability and efficiency under long-term use. The adjusting member includes a rotating mechanism with a pressing end 315. The pressing end 315 ensures good contact with the fixing portion 201 of the blade 2. During operation, the adjusting member is rotated by a tool, and the pressing end 315 rotates in the clamping groove 304, gradually pressing the fixing portion 201 of the blade 2, thereby achieving reliable fixing of the blade 2. The adjusting member has a built-in spring or similar mechanism to ensure that a stable pressing force can be maintained even when it is not rotating to avoid loosening due to vibration.

[0046] When the blade 2 needs to be replaced or adjusted, first loosen the adjustment member so that the extrusion end 315 releases the pressure on the fixing portion 201, and then the blade 2 can be easily removed. When replacing a new blade 2, it is only necessary to insert the fixing portion 201 of the new blade 2 into the card slot 304, and apply pressure by rotating the extrusion end 315 of the adjustment member to quickly complete the installation and fixation. The entire process does not require the disassembly of the impeller 1, which greatly improves work efficiency and flexibility. Through the above design, the multifunctional impeller 1 of this embodiment not only realizes the rapid replacement and diversified configuration of the blade 2, but also ensures the stability of the blade 2 in long-term operation through the innovative design of the adjustment member.

[0047] Furthermore, the accommodating groove 101 has a first opening 322 and a second opening 341 . The first opening 322 is located on the top surface of the impeller 1 ; the second opening 341 is located on the circumference of the outer wall of the impeller 1 .

[0048] In the above scheme, each receiving groove 101 is designed with two openings, namely the first opening 322 and the second opening 341. The first opening 322 is located on the top surface of the impeller 1, providing a direct and spacious passage for the insertion of the blade 2, so that the operator can intuitively see and easily align the fixing portion 201 of the blade 2 with the slot 304 for insertion, which greatly facilitates the installation and removal of the blade 2 without the need for complex operating space or special tools. The second opening 341 is located on the circumference of the outer wall of the impeller 1, corresponding to the first opening 322, forming a passage running through the inside and outside of the impeller 1. The second opening 341 is used to provide space for the fixing portion 201 after installation, and is convenient for confirming whether the blade 2 has been fully compressed, thereby improving the accuracy and safety of the installation. In actual operation, the operator first aligns the fixing portion 201 of the blade 2 with the slot 304 through the first opening 322, and then performs preliminary alignment and adjustment through the second opening 341 to ensure that the blade 2 is in the correct position. Then, the adjusting member is rotated by a tool, and the extruding end 315 rotates in the slot 304 and gradually presses the fixing portion 201 until the required tightening degree is reached. When the blade 2 needs to be maintained or replaced, the adjusting member is loosened through the second opening 341 to release the pressure on the fixing portion 201 of the blade 2, and the blade 2 is conveniently taken out through the first opening 322, which simplifies the maintenance process and reduces the maintenance cost.

[0049] Furthermore, the fixing portion 201 of the blade 2 is a T-shaped plug.

[0050] In the above scheme, the fixing portion 201 of the blade 2 is designed as a T-shaped plug, wherein the “|” portion is firmly connected to the main body of the blade 2 to form an integral structure, thereby ensuring rigidity and stability when transmitting stirring power. The “—” portion serves as a plug inserted into the receiving groove 101 of the impeller 1 to ensure a perfect match with the card slot 304 on the impeller 1. The vertical portion of the T-shaped design is wider, which increases the contact area with the card slot 304 and improves the torsion resistance and pull-out resistance during fixing. The sizes of the first opening 322 and the second opening 341 are adapted to the cross-section of the T-shaped plug, so that the plug can be smoothly inserted and remain stable. During the insertion process, the “—” portion of the T-shaped plug first enters through the first opening 322, and then, through the rotation of the adjusting member, the extrusion end 315 thereof is used to apply pressure to the vertical portion of the T-shaped plug, thereby firmly locking it in the card slot 304.

[0051] Installation and fixing process: During operation, the staff first aligns the T-shaped plug of the blade 2 with the slot 304 through the first opening 322 on the top surface of the impeller 1, and gently pushes it in until the "—" part completely enters the interior of the impeller 1. Then, rotate the adjusting piece, and its extrusion end 315 presses the vertical part of the T-shaped plug to make it close to the wall of the slot 304 to complete the fixing of the blade 2. This design simplifies the installation process, reduces the possibility of incorrect installation, and improves work efficiency. The T-shaped plug design is not only easy to install, but also easy to maintain and replace. When the blade 2 needs to be replaced, just reverse the operation, loosen the adjusting piece, and the T-shaped plug can be easily pulled out of the receiving slot 101, which greatly shortens the maintenance time and reduces the difficulty of maintenance.

[0052] Furthermore, the clamp 3 also includes: a fixed seat 301, having a limiting groove 302, a clamping jaw 303 slidably arranged in the limiting groove 302, after the clamping jaw 303 is opened, the clamping jaw 303 and the limiting groove 302 form a clamping groove 3031, the clamping groove 3031 is connected to the card slot 304, and the clamping groove 3031 and the card slot 304 are combined to form a T-shaped groove, and the fixing part 201 is detachably arranged in the T-shaped groove.

[0053] In the above scheme, the clamp 3 includes a fixed seat 301, a limiting groove 302, and a clamping claw 303 slidably arranged in the limiting groove 302. The fixed seat 301 is the base of the clamping claw 303, providing a stable support platform, and the limiting groove 302 is arranged on it. The limiting groove 302 not only ensures the smooth sliding of the clamping claw 303, but also limits its excessive movement, thereby ensuring the controllability of the operation. The clamping claw 303 can be opened and closed along the limiting groove 302. When the clamping claw 303 is opened, it forms a clamping groove 3031 together with the limiting groove 302. This clamping groove 3031 is connected with the card slot 304 to form a continuous space, which is convenient for the insertion and removal of the T-shaped plug (the fixing part 201 of the blade 2). More importantly, when the clamping claw 303 is closed, it works together with the edge of the limiting groove 302 to effectively clamp the T-shaped plug, thereby increasing the safety and stability of the fixation. The combination of the clamping groove 3031 and the card slot 304 forms a T-shaped groove, which just matches the T-shaped plug of the fixing part 201 of the blade 2. The T-shaped plug can easily slide in from the end of the clamping groove 3031, pass through the card slot 304, and finally be completely embedded in the T-shaped groove, which simplifies the installation process and also ensures the accurate alignment and firm fixation of the blade 2. Operation process: When replacing or installing the blade 2, first open the clamping jaw 303. At this time, the clamping groove 3031 is in an open state. The operator can intuitively align the T-shaped plug of the blade 2 with the T-shaped groove and slide it into the card slot 304 along the clamping groove 3031. Then, through the operation of the adjustment member, the extrusion end 315 rotates to close the clamping jaw 303, exerts pressure on the T-shaped plug, and finally completes the fixation. This process is not only easy to operate, but also ensures the accuracy and safety of the installation of the blade 2.

[0054] Furthermore, the fixing seat 301 has a threaded hole on one side away from the second opening 341; the adjusting member also includes: a round rod 311, having a threaded section 313, the threaded section 313 having an external threaded portion, and the threaded section 313 is threadedly connected to the threaded hole; a nut 312, fixedly arranged on the round rod 311, and the nut 312 is located in the limiting groove 302; an extrusion block 314, arranged at one end of the round rod 311 away from the threaded section 313, and the end of the extrusion block 314 away from the round rod 311 is an extrusion end 315, and the extrusion block 314 is used to press the fixing portion 201 inserted into the slot 304.

[0055] In the above scheme, the adjusting member includes a round rod 311, a threaded section 313, a nut 312 and an extrusion block 314. The round rod 311 is the main part of the adjusting member, and a threaded section 313 is provided at one end thereof. The external threaded portion of the threaded section 313 matches the threaded hole on the side of the fixing seat 301 away from the second opening 341 to form a threaded connection. The round rod 311 rotates on the fixing seat 301, and the extension length of the round rod 311 is adjusted by the advance and retreat of the thread, thereby controlling the position of the extrusion block 314. The nut 312 is fixed on the round rod 311 and is located inside the limiting groove 302. The nut 312 is fixed to limit the lateral movement of the round rod 311, ensuring that the rotation action only causes the round rod 311 to advance and retreat along the axial direction. In this way, during the adjustment process, the cooperation between the nut 312 and the limiting groove 302 ensures the stability of the round rod 311 and the accuracy of the adjustment. The extrusion block 314 is installed at one end of the round rod 311 away from the threaded section 313. One end of the extrusion block 314 is fixed on the round rod 311, and the other end is the extrusion end 315, which faces the fixing portion 201 of the blade 2. When the round rod 311 rotates through the threaded connection, the extrusion block 314 will reciprocate along the axial direction, and its extrusion end 315 will penetrate into the slot 304 as the round rod 311 extends, exerting pressure on the fixing portion 201 (T-shaped plug) of the blade 2 inserted into the slot 304, thereby achieving the tightening of the blade 2. Operation process: When replacing or adjusting the blade 2, first loosen the nut 312 to relax the extrusion block 314, so as to facilitate the insertion or removal of the T-shaped plug of the blade 2. After adjusting the position of the blade 2, by rotating the round rod 311, the threaded section 313 of the round rod 311 moves forward in the threaded hole, driving the extrusion block 314 to approach the fixing portion 201 of the blade 2 until the required pressure is reached, and then the position of the round rod 311 is locked by the nut 312 to prevent loosening due to vibration.

[0056] Furthermore, the inner wall of the limiting groove 302 is an inclined surface, and the width of the limiting groove 302 gradually increases from the second opening 341 to the threaded hole; the outer wall of the clamping jaw 303 is an inclined surface structure, and after the extrusion block 314 drives the clamping jaw 303 to move toward the second opening 341, the clamping jaw 303 clamps the fixing part 201.

[0057] In the above scheme, the inner wall of the limiting groove 302 adopts a slope structure, and its width gradually increases from the end close to the second opening 341 to the direction of the threaded hole. This design of gradual width not only provides a smooth guide for the sliding of the clamping jaw 303, but also creates a larger space for the opening and closing of the clamping jaw 303, so that the clamping jaw 303 can be more fully opened, which is convenient for the insertion and removal of the fixed part 201 (T-shaped plug block) of the blade 2. The outer wall of the clamping jaw 303 is designed as a slope structure, which matches the slope of the limiting groove 302. This design makes it possible for the clamping jaw 303 to slide along the slope under the action of external force when the extrusion block 314 moves toward the second opening 341 along the round rod 311, and its opening gradually decreases until the two sides of the clamping jaw 303 are tightly fitted, forming a firm clamping of the fixed part 201 inserted into the slot 304. The slope design makes the clamping process natural and uniform, improves the distribution of the clamping force, reduces local stress concentration, and enhances the stability of the blade 2 fixation. When installing or replacing the blade 2, first rotate the round rod 311 of the adjusting member so that the extrusion block 314 drives the clamp 303 to move toward the second opening 341. At this time, the clamp 303 is in a fully open state, which is convenient for inserting or removing the T-shaped plug. After inserting the blade 2, rotate the round rod 311 in the opposite direction, and the extrusion block 314 pushes the clamp 303 to slide along the inclined surface toward the threaded hole. The inclined surface structure of the outer wall of the clamp 303 is closed, and the fixing part 201 is clamped. As the rotation continues, the clamping force gradually increases until the desired tightening state is reached. The fixing of the nut 312 further ensures the stability of the adjusted state to prevent accidental loosening.

[0058] Furthermore, the fixing seat 301 has a groove 3012 on the top, a mounting hole 3013 in the groove 3012 , and also includes: a limiting plate, which is arranged in the groove 3012 , the bottom surface of the limiting plate abuts against the top surface of the clamping jaw 303 , and the limiting plate is used to limit the clamping jaw 303 .

[0059] In the above solution, a groove 3012 is added to the top of the fixing seat 301, which not only provides space for the installation of the limit plate, but also increases the structural integrity. One or more mounting holes 3013 are also provided in the groove 3012, and these mounting holes 3013 are used to fix the limit plate to ensure its stability and non-displacement during operation. The limit plate is designed as a component with a size and shape matching the bottom of the groove 3012, and its bottom surface is flat and directly abuts against the top surface of the clamping jaw 303. This design plays a dual role: first, the limit plate acts as a direct support for the clamp 303, enhancing the stability of the clamp 303 in the closed state, and preventing the clamp 303 from being deformed or displaced during high-load mixing operations; second, the limit plate limits the maximum opening and closing angle of the clamp 303, ensuring that the clamp 303 can provide enough space in the open state to facilitate the insertion or extraction of the blade 2 fixing portion 201, and at the same time, when closed, the limit plate forces the clamp 303 to be precisely aligned along a predetermined trajectory, achieving uniform and powerful clamping. During installation, the limit plate is fixed in the groove 3012 of the fixing seat 301 through the mounting hole 3013 to ensure that it fits tightly with the top surface of the clamp 303. Subsequently, the fixing part 201 of the blade 2 is smoothly inserted through the clamping groove 3031 and the clamping groove 304, and the round rod 311 is adjusted so that the extrusion block 314 drives the clamping jaw 303 to close. Under the guidance and restriction of the limit plate, the clamping jaw 303 applies uniform pressure to the fixing part 201 to complete the fastening. The existence of the limit plate makes the entire operation process more controllable, avoids excessive opening or loose closing caused by human factors, and ensures the consistency and reliability of each installation.

[0060] Furthermore, it also includes: a cover plate, which is hinged on the impeller 1, and the cover plate has fastening bolts. After the cover plate is closed, the fastening bolts are threadedly connected to the mounting holes 3013, and the cover plate is used to cover the first opening 322.

[0061] In the above scheme, the cover plate is made of a high-strength material compatible with the material of the impeller 1 to ensure durability and sealing. The size of the cover plate precisely matches the contour around the first opening 322 on the impeller 1, and is designed with an edge flange or other sealing structure to ensure a close fit with the surface of the impeller 1. A hinge is installed on one edge or multiple positions of the cover plate, so that the cover plate can be easily opened and closed. When the first opening 322 needs to be closed, the cover plate is closed on the impeller 1, and the preset fastening bolts on it are aligned with the mounting holes 3013 in the top groove 3012 of the fixing seat 301. By rotating the fastening bolts, the threaded portion thereof engages with the inner wall of the mounting hole 3013, thereby firmly fixing the cover plate on the impeller 1, effectively covering the first opening 322, preventing foreign matter from entering the interior of the impeller 1 during operation, and also protecting the internal structure from external environmental influences, such as dust, moisture, etc. During daily maintenance or replacement of the blades 2, the operator only needs to reversely loosen the fastening bolts to easily open the cover plate and expose the first opening 322. After completing the installation, adjustment or cleaning of the blades 2, the cover plate is closed again and the bolts are tightened to restore the normal working state of the impeller 1. This design simplifies the maintenance process, improves the maintenance efficiency of the impeller 1 assembly, and enhances the safety of the operation.

[0062] Furthermore, the bottom surface of the fixing seat 301 has a slide groove 306 , which is connected to the limiting groove 302 , and also includes: a slide rod 305 , one end of which is arranged on the clamping claw 303 , and the other end is slidably arranged in the slide groove 306 .

[0063] In the above scheme, the bottom surface of the fixed seat 301 is designed with a slide groove 306 connected to the limit groove 302, which not only provides a path for the sliding of the slide rod 305, but also ensures the direct connection between the movement of the slide rod 305 and the opening and closing action of the clamping jaw 303, thereby improving the overall coordination of the system. One end of the slide rod 305 is fixed to the clamping jaw 303, usually by welding, screw fixing or other reliable connection methods, to ensure a stable connection between the two. The other end of the slide rod 305 is slidably arranged in the slide groove 306 on the bottom surface of the fixed seat 301. When the slide rod 305 moves in the slide groove 306 along the specified direction, due to its integrated connection with the clamping jaw 303, it will directly drive the clamping jaw 303 to open and close along the limit groove 302, thereby achieving accurate clamping and release of the fixed part 201 of the blade 2. The operator can adjust the opening and closing of the clamping jaw 303 by directly controlling the sliding of the slide rod 305, without the need for additional complex operations, thereby improving the convenience and efficiency of operation. For example, when the blade 2 needs to be replaced, the clamping jaws 303 are opened by pushing the sliding rod 305, and the blade 2 is easily removed; when installing, the fixing portion 201 of the blade 2 is inserted, the sliding rod 305 is retracted, and the clamping jaws 303 are automatically closed and clamp the fixing portion 201. The introduction of the sliding rod 305 makes the whole process more intuitive and controllable.

[0064] Furthermore, the impeller 1 has an axial hole 102, and the axial hole 102 has a keyway 103.
