Technical Field

[0001] This utility model belongs to the field of magnetic pump technology, specifically a magnetic pump that is easy to maintain. Background Technology

[0002] A magnetic drive pump is a leak-free, fully sealed centrifugal pump that uses magnetic coupling drive instead of traditional mechanical seals. It is suitable for conveying toxic, flammable, explosive, or high-purity media. Its core principle is to drive the impeller to rotate through the magnetic coupling between the outer and inner magnetic rotors, while the isolation sleeve (sealing sleeve) completely isolates the media from the motor, eliminating the risk of leakage.

[0003] In the assembly of traditional magnetic pumps, a cylinder is usually connected between the motor and the pump body to achieve a three-way linkage. The cylinder is usually installed through a flange assembly, which requires the use of tools to tighten multiple sets of bolts during installation and disassembly, thus affecting the efficiency of disassembly and maintenance. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a magnetic pump that is easy to maintain. It solves the problem that the installation of the cylinder usually involves flange assembly, which requires the use of tools to tighten multiple sets of bolts during installation and disassembly, thus affecting the efficiency of disassembly and maintenance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a magnetic pump that is easy to maintain, comprising a fixing plate, fixing holes on both sides of the fixing plate, a support frame connected above the fixing plate, a drive motor fixedly mounted on the fixing plate, a pump body provided on the fixing plate, a connecting disc one connected to the drive motor, a connecting disc two connected to the pump body, a connecting sleeve frame installed between the connecting disc one and the connecting disc two, and two arc-shaped plates connected to both the connecting disc one and the connecting disc two;

[0006] The arc-shaped plate has a slot, and the upper arc-shaped plates of the first and second connecting plates are connected by a main clamp, and the lower arc-shaped plates of the first and second connecting plates are connected by a secondary clamp. The support frame is connected to a wind duct, and a working motor is fixedly installed inside the wind duct. The output shaft of the working motor is equipped with fan blades.

[0007] As a further embodiment of this utility model: the main clamp is rotatably connected to both sides with screws, and one end of the screw is threadedly connected to a tightening component. The tightening component is in close contact with the secondary clamp and is provided with anti-slip texture.

[0008] As a further embodiment of this utility model: the two ends of the connecting cylinder frame are respectively inserted into the connecting plate one and the connecting plate two, and slots are provided on the protruding edges on both sides of the connecting cylinder frame.

[0010] As a further embodiment of this utility model: the air duct is located directly above the drive motor, and filter plates are connected above and below the air duct, with the working motor and fan blades disposed between the two filter plates.

[0011] As a further embodiment of this utility model: notches and grooves are provided on both sides of the secondary clamp, and the screw is engaged in the notches and grooves.

Detailed Implementation

[0020] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0021] like Figure 1-4 As shown, this utility model provides a technical solution: a magnetic pump that is easy to maintain, including a fixed plate 1, with fixed holes 2 on both sides of the fixed plate 1, a support frame 3 connected above the fixed plate 1, a drive motor 4 fixedly installed on the fixed plate 1, a pump body 5 provided on the fixed plate 1, a connecting plate 6 connected to the drive motor 4, a connecting plate 7 connected to the pump body 5, a connecting sleeve 8 installed between the connecting plate 6 and the connecting plate 7, with both ends of the connecting sleeve 8 inserted into the connecting plate 6 and the connecting plate 7 respectively, and slots 18 provided on the protruding edges on both sides of the connecting sleeve 8. By inserting the two ends of the connecting sleeve 8 into the connecting plate 6 and the connecting plate 7, it is convenient for the staff to perform axis positioning, and the fixed plate 1 can be fixed by screwing bolts into the fixed holes 2 to prevent slippage during operation.

[0022] Both connecting plate 6 and connecting plate 7 are connected to two arc-shaped plates 9. The arc-shaped plates 9 have slots 10. The arc-shaped plates 9 are inserted into slots 18. The main clamp 11 and the auxiliary clamp 12 are specifically engaged in the slots 10 on the arc-shaped plates 9. The main clamp 11 and the auxiliary clamp 12 are in close contact with the protruding edge of the connecting cylinder frame 8. By inserting the arc-shaped plates 9 into the slots 18, the connecting cylinder frame 8 can be fixed between connecting plate 6 and connecting plate 7 to prevent it from falling or moving. The slots 10 can limit the main clamp 11 or the auxiliary clamp 12 to prevent them from sliding or shifting.

[0023] The main clamp 11 is connected to the arc plate 9 on the upper side of the connecting plate 11 and the connecting plate 2. The main clamp 11 is rotatably connected to the two sides of the main clamp 11. One end of the screw 13 is threadedly connected to the tightening part 14. The tightening part 14 is in close contact with the secondary clamp 12 and is provided with anti-slip texture. The anti-slip texture on the tightening part 14 can increase friction, thereby making it convenient for workers to tighten without the need for tools, simplifying the operation.

[0024] A secondary clamp 12 is attached to the arc-shaped plate 9 on the lower side of the connecting plate 6 and the connecting plate 7. The secondary clamp 12 has notches 20 on both sides. The screw 13 is engaged in the notch 20. By rotating the screw 13, the screw 13 is driven into the notch 20. Then, the tightening member 14 is turned to tighten and fix the secondary clamp 12, so that the main clamp 11 and the secondary clamp 12 are locked and fixed to the connecting cylinder frame 8, preventing the connecting cylinder frame 8 from moving and falling.

[0025] A fan duct 15 is connected to the support frame 3. A working motor 16 is fixedly installed inside the fan duct 15. A fan blade 17 is installed on the output shaft of the working motor 16. The fan duct 15 is located directly above the drive motor 4. Filter plates 19 are connected above and below the fan duct 15. The working motor 16 and the fan blade 17 are arranged between the two filter plates 19. The filter plates 19 filter and block dust in the air, thereby preventing dust from adhering to the fan blade 17 and ensuring the normal operation of the fan blade 17.

[0026] The working principle of this utility model is as follows:

[0027] By inserting the arc plate 9 into the slot 18, the slot 10 passes through the slot 18, allowing the two ends of the connecting cylinder 8 to be inserted into the connecting plate 6 and the connecting plate 7 respectively. Then, the main clamp 11 and the auxiliary clamp 12 are inserted into the slot 10 in an up-down distribution, so that the main clamp 11 and the auxiliary clamp 12 are in close contact with the connecting cylinder 8. Then, the screw 13 is rotated to be inserted into the notch 20, and the tightening member 14 is tightened to press and fix the auxiliary clamp 12, so that the main clamp 11 and the auxiliary clamp 12 are combined and connected together, fixing the connecting cylinder 8 between the connecting plate 6 and the connecting plate 7. The operation is simple and does not require the use of tools to tighten multiple sets of bolts. The working motor 16 can rotate the fan blade 17 during operation, causing the fan blade 17 to blow air and accelerate the airflow around the drive motor 4 to improve heat dissipation efficiency.

[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
