Description

Technical Field

[0001] The invention relates to the technical field of magnetic pumps, in particular to a vertical magnetic pump with gas protection capable of conveying slurry. Background Art

[0002] The vertical magnetic pump is a new type of seal-less pump that uses the principle of permanent magnetic transmission technology to achieve contactless transmission of torque. There is no mechanical connection between the driving shaft and the driven shaft, and no dynamic seal is required in the structure. Therefore, this type of pump is seal-free and can achieve zero leakage. It is particularly suitable for conveying flammable, explosive, volatile, toxic, corrosive and precious liquids. However, when outputting flammable, explosive, volatile, toxic, corrosive and precious liquids, a protective gas such as nitrogen or other inert gas will be filled into the isolation sleeve of the magnetic pump to ensure that the pressure inside the isolation sleeve is higher than the pressure of the pumped medium, to prevent the medium from leaking into the isolation sleeve, and to prevent external air from entering the pump, thereby protecting the magnet inside the pump from corrosion and oxidation.

[0003] Since the vertical magnetic pump is designed so that the pump body does not usually bear the weight of the pipeline, if the pump body is installed vertically, the weight of the pipeline may cause additional burden on the pump body, affecting the normal operation and service life of the pump. At the same time, the working principle of the magnetic pump is that the motor drives the outer magnetic rotor to rotate, and the magnetic field penetrates the isolation sleeve to drive the inner magnetic rotor connected to the impeller to rotate synchronously, realizing non-contact synchronous transmission of shaft power. Horizontal installation helps to maintain the efficiency and stability of magnetic transmission; Therefore, the vertical magnetic pump needs to be installed horizontally on the ground during installation. Since the existing vertical magnetic pump lacks a leveling mechanism on the installation base, when installing the vertical magnetic pump on an inclined or bumpy ground, the installer needs to lift the vertical magnetic pump and add gaskets to level it to ensure that the vertical magnetic pump is installed horizontally, which is not only time-consuming and labor-intensive, but also greatly reduces the installation efficiency of the device.

[0004] Therefore, a vertical magnetic pump with gas protection and capable of conveying slurry is proposed to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0018] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0020] like Figure 1-9 The vertical magnetic pump with gas protection capable of conveying slurry shown in the figure comprises a magnetic pump body 1. When assembling the vertical magnetic pump, a protective gas is filled into the isolation sleeve of the magnetic pump body 1 to ensure that the pressure inside the isolation sleeve is higher than the pressure of the pumped medium, to prevent the medium from leaking into the isolation sleeve, and to prevent external air from entering the pump, thereby protecting the magnet inside the pump from corrosion and oxidation, thereby realizing the gas protection function of the vertical magnetic pump, and a mounting plate 2 fixedly connected to the bottom of the magnetic pump body 1, and a plurality of mounting holes 3 are evenly spaced on the top of the mounting plate 2. , through the mounting hole 3, the screw on the ground is convenient to pass through the vertical magnetic pump for fixing. A driving motor 8 is provided on the top of the magnetic pump body 1. When the driving motor 8 is controlled to start rotating, the driving motor 8 drives the outer magnetic rotor on the magnetic pump body 1 to rotate. The magnetic field of the outer magnetic rotor is transmitted to the inner magnetic rotor through the isolation sleeve (usually made of non-magnetic, high-strength material). The inner magnetic rotor rotates synchronously under the action of the magnetic field of the outer magnetic rotor. At the same time, the inner magnetic rotor is fixedly connected to the impeller of the pump. The rotation of the inner magnetic rotor directly drives the impeller to rotate, thereby realizing the transportation of the fluid; The inlet and outlet ends of the magnetic pump body 1 are fixedly connected with a connecting flange 33 for connecting to an external pipeline, which is convenient for connecting to an external pipeline through the connecting flange 33. An L-shaped groove 4 is provided in an annular manner on the outer wall of the mounting plate 2, and an L-shaped block 5 is slidably connected to the inner side of the L-shaped groove 4. An upper cylinder 6 is fixedly connected to the side wall of the L-shaped block 5, and a lower cylinder 7 is rotatably connected to the inner side of the upper cylinder 6. A round block 9 is fixedly connected to the bottom of the lower cylinder 7. A rectangular groove 10 is provided through the top of the round block 9, and a rectangular block 11 is slidably connected to the inner side of the rectangular groove 10. An adjusting plate 12 is provided at the bottom of the round block 9, and a connecting rod 13 is fixedly connected between the rectangular block 11 and the adjusting plate 12. A top plate 14 is fixedly connected to the top of the upper cylinder 6, and a threaded rod 15 is threadedly connected to the top of the top plate 14. The bottom of the threaded rod 15 is rotatably connected to the top of the rectangular block 11, and an adjusting mechanism for rotating the position of the adjusting plate 12 is provided on the lower cylinder 7; When installing the vertical magnetic pump, first pass the mounting hole 3 on the mounting plate 2 through the screw fixed on the ground, and then use a level ruler to check the horizontality of the mounting plate 2, the magnetic pump body 1 and the drive motor 8. If there is a deviation, the L-shaped block 5 can be inserted into the L-shaped groove 4 through the top groove 20, and then the adjustment plate 12 at the bottom of the L-shaped block 5 can be rotated to the position that needs to be adjusted. Then, the polygonal block 16 can be rotated with a wrench to drive the threaded rod 15 to rotate. Since the threaded rod 15 and the top plate 14 are threadedly connected, the threaded rod 15 will move downward in a spiral when it rotates, thereby pushing the bottom rectangular block 11 to slide inside the rectangular groove 10. At this time, the threaded rod 15 will rotate at the top of the rectangular block 11, thereby sliding downward through the rectangular block 11. The adjusting plate 12 is driven to move downward at the same time by the connecting rod 13 to support the mounting plate 2 from the inclined position until the mounting plate 2, the magnetic pump body 1 and the drive motor 8 are in a horizontal state. If the bottom of the mounting plate 2 is tilted in more than one place at this time, an L-shaped block 5 can be taken and inserted into the L-shaped groove 4 from the top groove 20 on the other side, and rotated to the specified position for adjustment, thereby completing the rapid leveling of the vertical magnetic pump. There is no need for the installer to lift the vertical magnetic pump and insert the gasket, which saves time and effort. Finally, after the leveling is completed, the nut can be screwed into the inserted screw and tightened. After tightening, the level of the vertical magnetic pump needs to be measured again. If the vertical magnetic pump is tilted after tightening, the nut needs to be loosened and the polygonal block 16 needs to be adjusted again until the vertical magnetic pump is installed in a horizontal state.

[0021] In order to further improve the convenience of the device, a polygonal block 16 is fixedly connected to the top of the threaded rod 15. The setting of the polygonal block 16 makes it convenient for the installer to use a wrench to rotate the polygonal block 16, thereby driving the threaded rod 15 to rotate and driving the adjustment plate 12 to move downward quickly for adjustment, making the adjustment process more labor-saving. An upper anti-slip pad 17 is fixedly connected to the bottom of the adjustment plate 12. The setting of the upper anti-slip pad 17 can prevent the adjustment plate 12 from sliding randomly after being placed on the ground, thereby further improving the convenience of the device during installation.

[0022] In order to improve the stability of the device during adjustment, four guide grooves 18 are opened inside the rectangular groove 10, and guide blocks 19 are fixedly connected to the outer wall of the rectangular block 11 and at positions corresponding to the four guide grooves 18, and the guide blocks 19 are slidably connected to the inner side of the guide grooves 18; By setting the guide groove 18 and the guide block 19, when the threaded rod 15 rotates to push the rectangular block 11 to slide downward, the guide block 19 can be driven to slide inside the guide groove 18, thereby playing a guiding role, preventing the rectangular block 11 from rotating with the threaded rod 15, and improving the stability of the device during operation.

[0023] In order to fix the positions of the adjusted L-shaped block 5 and the upper cylinder 6, a pair of top grooves 20 are provided on the top of the mounting plate 2 and above the L-shaped groove 4, and an arc block 21 is provided on the top of the L-shaped block 5. The length of the arc block 21 is set to a position where both sides can be squeezed by the nuts installed on the two mounting holes 3, so that no matter what position the arc block 21 rotates to, there can be a nut that can squeeze and fix it. When installing and fixing, the screw on the ground is passed through the mounting hole 3, and then the nut is screwed into each screw and tightened to fix it, so that the arc block 21 is squeezed and fixed between the nut and the mounting plate 2, so as to achieve the locking and fixing of the L-shaped block 5; When the position of the adjusting plate 12 is adjusted, the nut can be screwed into the passed screw. At this time, the arc block 21 is located under one or two nuts. Then the nut is tightened. The arc block 21 is squeezed between the thread and the mounting plate 2 by the nut, and the arc block 21 can be clamped to fix the position of the L-shaped block 5 and the upper cylinder 6. This avoids displacement of the L-shaped block 5 due to vibration during subsequent use, which affects the effect of maintaining the horizontal level of the vertical magnetic pump after installation. At the same time, the L-shaped block 5 can be fixed while tightening the nut, which saves time and effort and further improves the practical performance of the device.

[0024] In order to further improve the practicality of the device, a connecting block 32 is fixedly connected to the top of the L-shaped block 5 and located on the outside of the mounting plate 2. The top of the connecting block 32 is fixedly connected to the bottom of the arc block 21. The setting of the connecting block 32 not only ensures the connection between the L-shaped block 5 and the arc block 21, but also ensures that the L-shaped block 5 will not be hindered when sliding out of the top groove 20, thereby avoiding affecting the normal operation of the device. A lower anti-slip pad 31 is fixedly connected to the top of the arc block 21. The setting of the lower anti-slip pad 31 can increase the anti-slip performance of the nut when squeezing the arc block 21, thereby avoiding the nut slipping and affecting the locking and fixing of the nut.

[0025] In order to be able to adjust the supporting direction of the adjustment plate 12 according to the inclination of the bottom of the mounting plate 2, the adjustment mechanism includes an extrusion rod 22, four vertical grooves 23 are equidistantly opened on the inner side of the lower cylinder 7, arc-shaped inclined grooves 24 are opened between the four vertical grooves 23, and the two ends of the arc-shaped inclined grooves 24 are respectively connected to the upper and lower ends of two adjacent vertical grooves 23, the extrusion rod 22 penetrates and slides to the top of the top plate 14, the bottom of the extrusion rod 22 is fixedly connected to the sliding frame 34, the side wall of the sliding frame 34 penetrates and slides to be connected, the side wall of the round rod 25 is fixedly connected to the side plate 26, and the upper plate 26 is fixedly connected to the inner side of the sliding frame 34. Spring 27, through the setting of the upper spring 27, it is convenient to quickly push the end of the round rod 25 into the groove 28, the top of the vertical groove 23 is provided with an inward groove 28, and the connection between the groove 28 and the arc-shaped inclined groove 24 is inclined, and a lower spring 29 is fixedly connected between the bottom of the sliding frame 34 and the top of the round block 9. The lower spring 29 facilitates the sliding frame 34 to slide upward and reset when the extrusion rod 22 is released. The end of the round rod 25 is inserted into the inner side of one of the grooves 28, and the bottom of the groove 28 is set to an inclined surface with the same slope as the arc-shaped inclined groove 24, so as to facilitate the round rod 25 to be squeezed into the arc-shaped inclined groove 24 more smoothly; When a pit in the same direction as the adjustment plate 12 appears at the bottom of the mounting plate 2, and the adjustment plate 12 needs to be rotated for support adjustment, the extrusion rod 22 can be pressed downward to drive the sliding frame 34 to slide downward. At this time, the end of the round rod 25 is inserted into the groove 28. Since there is a step between the groove 28 and the vertical groove 23, the outer wall of the round rod 25 will squeeze the inclined surface at the bottom of the groove 28 when the extrusion rod 22 pushes the round rod 25 to slide downward, so that the lower cylinder 7 moves on the inner side of the upper cylinder 6. Rotate, and drive the round block 9, the rectangular block 11, the connecting rod 13 and the adjusting plate 12 to rotate at the same time. At this time, the rectangular block 11 will rotate at the bottom of the threaded rod 15, and then the round rod 25 will slide out of the groove 28 and slide into the arc-shaped inclined groove 24. Because the depth of the groove 28 and the arc-shaped inclined groove 24 are different, when the round rod 25 slides out of the groove 28, the round rod 25 will gradually be squeezed outward to slide, and the upper spring 27 will be gradually stretched outward, and then the squeezing rod 22 drives the round rod 25 to slide out of the arc-shaped inclined groove 24; During this process, the sliding frame 34 will be driven to gradually move downward and compress the lower spring 29. When the squeezing rod 22 cannot be pushed downward, the squeezing rod 22 can be released. At this time, the round rod 25 slides out from the inside of the arc-shaped inclined groove 24 and slides into the vertical groove 23. After the squeezing rod 22 is released, the sliding frame 34 will be pushed to slide upward under the elastic force of the lower spring 29, and the round rod 25 will be driven to slide on the inside of the vertical groove 23. Then the sliding frame 34 and the squeezing rod 22 are reset. At this time, the round rod 25 moves to the side of the groove 28, and then the elastic force of the upper spring 27 pushes the end of the round rod 25 to be inserted into the groove 28, thereby realizing the adjustment of the support position of the adjustment plate 12. It can be flexibly adjusted according to the actual situation, further improving the convenience of the device. When it needs to be adjusted back, press the squeezing rod 22 again for squeezing.

[0026] In order to avoid affecting the normal adjustment of the device, an annular groove 30 is opened at the bottom of the mounting plate 2. The setting of the annular groove 30 can avoid hindering the normal rotation of the adjustment plate 12, thereby affecting the rapid adjustment of the tilt position of the bottom of the mounting plate 2.
