Description

Technical Field

[0001] This utility model relates to the field of pump technology, and in particular to a magnetic impeller for quick replacement of water blades. Background Technology

[0002] Magnetic drive pumps, as leak-free and highly sealed fluid transport devices, are widely used in fields with high safety and environmental requirements, such as chemical, pharmaceutical, and electroplating industries. They achieve non-contact power transmission through magnetic couplers, thus completely solving the leakage problem at the shaft seal of traditional pumps. The impeller, as the core flow-through component of the magnetic drive pump, directly affects the pump's efficiency, head, flow rate, and operating energy consumption.

[0003] In practical applications, different industries or different processes within the same industry have significantly different performance requirements for pumps. For example, parameters such as flow rate and head need to be matched according to specific operating conditions. Currently, many magnetic drive pumps use a single-design impeller (water blade). While this fixed structure can meet some operating conditions, its operating range is relatively narrow. When the customer's actual operating conditions deviate from the design conditions, the pump efficiency often drops significantly, leading to increased energy consumption and poorer operating economy.

[0004] To meet diverse customer needs, manufacturers typically need to offer a variety of impellers with different performance specifications for selection. This presents new challenges in practice: on the one hand, manufacturers need to stock large quantities of different impeller models, increasing management costs and inventory pressure; on the other hand, when impeller replacement is required to adapt to changes in operating conditions or for maintenance, traditional installation methods are often cumbersome, involving numerous disassembly and assembly steps, and are time-consuming, affecting the flexibility of equipment use and maintenance efficiency. Therefore, how to achieve quick and easy impeller replacement without affecting the main pump structure, thereby flexibly matching different operating conditions and reducing maintenance time, has become a technical problem worth solving in this field. Utility Model Content

[0005] Based on the above, the purpose of this utility model is to provide a quick-replacement magnetic impeller for water blades, which enables rapid replacement of the impeller.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: This utility model provides a quick-replacement magnetic impeller, including a pump body and an impeller, wherein the pump body and the impeller are detachably connected; The pump body includes a central through hole, and two symmetrically arranged horizontal slots are provided near the top of the pump body. The two sides of the horizontal slots extend to the central through hole and the outer periphery of the top of the pump body, respectively. At least three sets of vertical slots are also provided at equal intervals on the outer periphery of the top of the pump body. The bottom of the impeller is provided with a first slot corresponding to the horizontal slot and a second slot corresponding to the vertical slot; A first pin is inserted into the transverse slot and the first slot; The second pin is inserted into the vertical slot and the second slot.

[0007] Preferably, the second slot is a T-shaped slot, and the second pin is a T-shaped pin.

[0008] Preferably, a bushing is detachably provided inside the central through hole, and the bushing can abut against the side of the first pin near the central through hole.

[0009] The beneficial effects of this utility model are as follows: This invention establishes an impeller connection and fixing method by setting horizontal and vertical slots, along with corresponding first and second pins. This structure enables quick assembly and disassembly between the impeller and the pump body; operation is completed simply by inserting or removing the pins, greatly simplifying replacement steps, shortening maintenance time, and effectively solving the problems of cumbersome and time-consuming traditional methods. Simultaneously, this structure allows the same pump body to flexibly adapt to various impellers (water blades) with different performance specifications. Users can quickly replace the corresponding impeller according to actual operating conditions without replacing the entire pump body or performing complex modifications, thus ensuring the pump always operates in its high-efficiency range and significantly reducing energy loss due to mismatched operating conditions. Furthermore, this connection structure is robust and reliable. In particular, the detachable bushing abuts against the first pin, preventing it from disengaging when locked, ensuring the impeller does not detach from the pump body during rotation and preventing slippage.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. 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.

[0017] like Figures 1 to 5 As shown, this utility model embodiment provides a quick-change magnetic impeller, which includes a pump body 1, an impeller 2, a first pin 3, and a second pin 4.

[0018] The pump body 1 serves as the mounting base, and its center has a central through hole 11 for a drive shaft (not shown in the figure) to pass through. Near the top of the pump body 1, two symmetrical transverse slots 12 are formed circumferentially. One side (inner side) of each transverse slot 12 radially penetrates the wall of the central through hole 11, while the other side (outer side) penetrates to the outer circumferential surface of the top of the pump body 1, thus forming two radial through slots. Furthermore, on the outer circumferential surface of the top of the pump body 1, at least three sets of vertical slots 13 are evenly distributed circumferentially. These vertical slots 13 extend downwards from the top surface of the pump body 1 to a certain depth.

[0019] The bottom of the impeller 2 (i.e., the water blade) facing the pump body 1 is provided with a connection structure that cooperates with the structure of the pump body 1. Specifically, the bottom of the impeller 2 has a pair of first slots 21 corresponding to the positions of the two horizontal slots 12. At the same time, the bottom of the impeller 2 has second slots 22 corresponding to the positions of the at least three sets of vertical slots 13, with the number and position matching each other.

[0020] The first pin 3 is used to connect the impeller 2 to the pump body 1, preventing the impeller 2 from disengaging from the pump body 1 during operation. During installation, the first pin 3 is inserted through the central through-hole 11 of the pump body 1, and then passes sequentially through the transverse slot 12 and the first slot 21 on the impeller 2. The insertion of the first pin 3 effectively transmits torque, preventing relative rotation between the impeller 2 and the pump body 1.

[0021] The second pin 4 is used to fix the impeller 2 and assist in circumferential positioning in the axial direction to the pump body 1. During installation, the second pin 4 is inserted axially from top to bottom, simultaneously embedding into the vertical slot 13 of the pump body 1 and the second slot 22 of the impeller 2. The insertion of the second pin 4 restricts the axial movement of the impeller 2 relative to the pump body 1, ensuring operational stability.

[0022] It should be noted that during installation, the second pin 4 should be installed first, followed by the first pin 3.

[0023] In a preferred embodiment, the second slot 22 is designed as a T-slot, and correspondingly, the second pin 4 is a mating T-pin. The T-shaped structure has a larger contact area and better shear resistance, enabling it to withstand axial forces more reliably, preventing the second pin 4 from accidentally loosening during operation, and further improving the strength of the connection.

[0024] In a preferred embodiment, to enhance the rigidity of the overall structure and ensure the reliable installation of the first pin 3, a detachable bushing 5 is also provided inside the central through hole 11. This bushing 5 is fitted over the drive shaft. When the first pin 3 is inserted into place, the bushing 5 is inserted from above the central through hole 11, and its outer wall abuts against the inner end of the first pin 3 near the central through hole 11. The bushing 5 acts as an axial limiting block, preventing the first pin 3 from loosening or falling off towards the pump center due to vibration or centrifugal force during operation, thereby ensuring the durable and reliable transmission connection.

[0025] The installation process of this utility model is as follows: When it is necessary to install the impeller 2, firstly, install the second pin 4 on the pump body 1, then align the first slot 21 and the second slot 22 at the bottom of the impeller 2 with the horizontal slot 12 and the vertical slot 13 on the pump body 1, respectively, and then fit the impeller 2 onto the top of the pump body 1. Next, insert the first pin 3 radially, so that it passes through the horizontal slot 12 of the pump body 1 and enters the first slot 21 of the impeller 2. Finally, install the bushing 5, so that it abuts against the inner end of the first pin 3, and the installation is completed.

[0026] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention. The scope of the present invention is determined by the scope of the appended claims.
