Description

Technical Field

[0001] The invention relates to the technical field of thermal insulation fluorine-lined magnetic pumps, in particular to a fluorine-lined magnetic pump with thermal insulation effect. Background Art

[0002] Fluorine-lined magnetic pump is a new type of pump that uses modern magnetic mechanics principles and uses the magnetic transmission of permanent magnets to achieve contactless transmission of torque. When the motor drives the outer rotor (i.e., outer magnetic steel) assembly to rotate, through the action of the magnetic field, the magnetic lines of force pass through the isolation sleeve to drive the inner rotor (i.e., inner magnetic steel) assembly and the impeller to rotate synchronously. Since the medium is enclosed in the stationary isolation sleeve, the purpose of pumping the medium without leakage is achieved, which completely solves the shaft seal leakage problem of mechanical transmission pumps.

[0003] The existing fluorine-lined magnetic pumps all have a certain thermal insulation effect, but during long-term high-intensity work, it is inevitable that the inner and outer magnetic cylinder rotors will be misaligned, resulting in increased wear between the inner and outer magnetic cylinders and the isolation sleeves, which will cause corrosive liquids to leak and enter the fluorine-lined magnetic pump, causing corrosion to the internal insulation structure, thereby causing the fluorine-lined magnetic pump to lose its thermal insulation effect.

[0004] In view of the above problems, a fluorine-lined magnetic pump with thermal insulation effect is proposed. Summary of the invention

By adopting this device to work, the problem that the inner and outer magnetic cylinder rotors are inevitably misaligned during long-term high-intensity work in the above-mentioned background, thereby causing the wear between the inner and outer magnetic cylinders and the isolation sleeve to increase, which will cause the corrosive liquid to leak, allowing the corrosive liquid to enter the interior of the fluorine-lined magnetic pump, causing corrosion to the internal insulation structure, thereby causing the fluorine-lined magnetic pump to lose its thermal insulation effect.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a fluorine-lined magnetic pump with thermal insulation effect, comprising a base and a first support frame, a second support frame and a third support frame fixedly arranged on the base, a driving motor being fixedly installed on the upper end of the first support frame, a coupling being fixedly installed on the output end of the driving motor, a shell being fixedly installed on the upper end of the second support frame, an isolating component being arranged in the shell to prevent corrosive liquid from flowing into the shell due to long-term use, a detection component for rotor misalignment of inner and outer magnetic cylinders being arranged on the inner wall of the shell, a reset component for resetting the outer magnetic cylinder being arranged on the inner wall of the shell, an isolation sleeve being connected with a pin on the side wall of the shell, a rolling component for reducing the rotational friction of the outer magnetic cylinder being arranged on the reset component, and an adjustment component for adjusting the inner magnetic cylinder being arranged on the inner wall of the isolation sleeve.

[0007] Furthermore, the isolation component includes two bearings fixedly mounted on the inner wall of the outer shell, a pump outer shaft is rotatably mounted between the two bearings, the pump outer shaft is fixedly connected to a coupling, an external magnetic rotor is fixedly mounted on one end of the pump outer shaft, a pump casing is inserted and connected to the isolation sleeve, rubber rings are respectively arranged between the isolation sleeve and the pump casing and the outer shell, a rotating shaft is rotatably mounted on the middle end of the isolation sleeve, an internal magnetic rotor is fixedly mounted on the axial side wall of the rotating shaft, and an impeller is fixedly mounted on one end of the rotating shaft.

[0008] Furthermore, the detection component includes a first laser sensor fixedly mounted on the axial side wall of the outer magnetic rotor, a marking ring is arranged on the side wall of the isolation sleeve, the first laser sensor is aligned with the marking ring, and a second laser sensor is arranged on the inner wall of the outer shell.

[0009] Furthermore, the reset assembly includes two first hydraulic pumps fixedly mounted on the inner wall of the outer shell, the telescopic ends of the two first hydraulic pumps are fixedly mounted with first arc-shaped clamps, a connecting plate is fixedly mounted on the inner wall of the outer shell, a first tee is fixedly arranged on the upper end of the connecting plate, a first oil pipe is arranged between the first tee and the two first hydraulic pumps, and a first oil inlet pipe is arranged on the first tee.

[0010] Furthermore, the rolling assembly includes a plurality of mounting grooves provided on the first arc-shaped fixture, a rotating shaft is rotatably mounted on each of the plurality of mounting grooves, and a first roller is fixedly mounted on an axial side wall of the rotating shaft.

[0011] Furthermore, the adjustment assembly includes two second hydraulic pumps fixedly arranged on the isolation sleeve, the telescopic ends of the two second hydraulic pumps are fixedly installed with second arc-shaped clamps, a fixing plate is fixedly installed on the inner wall of the isolation sleeve, a second tee is fixedly installed on the lower end of the fixing plate, a second oil pipeline is arranged between the second tee and the second hydraulic pump, and a second oil inlet pipe is arranged on the second tee.

[0012] Furthermore, the infrared rays of the second laser sensor just touch the outer wall of the inner magnetic rotor.

[0013] Further, the size of the first arc-shaped clamp matches the size of the outer magnetic rotor, and the size of the second arc-shaped clamp matches the size of the inner magnetic rotor.

[0014] Furthermore, the first laser sensor and the marking circle are in the same position.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. With the cooperation of the driving motor, coupling, pump outer shaft and outer magnetic rotor, the magnetic coupling effect is used to generate a magnetic field, so that the magnetic field penetrates the isolation sleeve and is transmitted to the inner magnetic rotor, thereby driving the pump impeller to rotate, thereby transporting the corrosive liquid. However, due to the high working intensity of the fluorine-lined magnetic pump, it is inevitable that the pump will vibrate. In order to avoid the rigid connection between the isolation sleeve and the outer casing, thereby causing damage to the isolation sleeve due to vibration, the rubber ring can prevent the corrosive liquid from leaking from the junction to the outside of the fluorine-lined magnetic pump. The rubber ring can also reduce the vibration range of the isolation sleeve, which plays a protective role for the isolation sleeve.

[0017] 2. With the cooperation of the first laser sensor and the marking ring, the rotor misalignment can be detected at the first time, which can avoid further wear of the outer magnetic rotor and the bearing, and even cracks in the isolation sleeve, so that the corrosive liquid corrodes the insulation components of the fluorine-lined magnetic pump, causing the fluorine-lined magnetic pump to lose its insulation effect. The second laser sensor can detect the rotor misalignment of the inner magnetic rotor. When the second laser sensor cannot detect the inner magnetic rotor or the inner wall of the outer shell, it means that the inner magnetic rotor has a rotor misalignment, avoiding damage to the impeller.

[0018] 3. With the cooperation of the first laser sensor, the outer magnetic rotor, the controller, the oil pump, the oil, the first oil inlet pipe, the second oil inlet pipe, the first tee, the second tee, the first oil pipeline and the second oil pipeline, the first hydraulic pump and the second hydraulic pump start to work, which drives the first arc clamp and the second arc clamp to move to the middle. At this time, the two first arc clamps reset the outer magnetic rotor, and the two second arc clamps reset the inner magnetic rotor, which can prevent corrosive liquid from entering the fluorine-lined magnetic pump and causing corrosion to the insulation components. The first roller can effectively reduce the friction between the inner and outer magnetic cylinders and the clamps, and indirectly reduce the working energy consumption.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] In order to solve the technical problem that the isolation sleeve 23 is damaged due to the vibration of the fluorine-lined magnetic pump under long-term high-intensity work, resulting in the corrosive liquid corroding the insulation accessories of the fluorine-lined magnetic pump, such as Figure 1-Figure 2As shown, the following preferred technical solutions are provided: a fluorine-lined magnetic pump with thermal insulation effect, comprising a base 1 and a first support frame 11, a second support frame 12 and a third support frame 13 fixedly arranged on the base 1, a driving motor 14 is fixedly installed on the upper end of the first support frame 11, a coupling 15 is fixedly installed on the output end of the driving motor 14, a shell 16 is fixedly installed on the upper end of the second support frame 12, and an isolation component 2 is arranged in the shell 16 to prevent corrosive liquid from flowing into the shell 16 for a long time, which can prevent the corrosive liquid from rusting the parts in the fluorine-lined magnetic pump, thereby causing the fluorine-lined magnetic pump to lose its thermal insulation effect, a detection component 3 for the misalignment of the rotors of the inner and outer magnetic cylinders is arranged on the inner wall of the shell 16, which can timely detect the misalignment of the rotors of the inner and outer magnetic cylinders, and transmit the signal to the controller to avoid large vibration and wear caused by continuous operation, which causes the temperature of the fluorine-lined magnetic pump to rise and the thermal insulation effect to deteriorate, and a reset group for resetting the outer magnetic cylinder is arranged on the inner wall of the shell 16 Part 4, an isolation sleeve 23 is connected to the side wall of the shell 16 by a pin, and a rolling assembly 5 for reducing the rotation friction of the external magnetic cylinder is arranged on the reset assembly 4. When the detection assembly 3 detects that the rotor of the external magnetic steel is misaligned, a signal is transmitted to the controller, and then the hydraulic valve is started to transmit the hydraulic oil to the oil pump, so that the rolling assembly 5 is lifted by the oil pump, so that the external magnetic cylinder is reset to prevent the external magnetic cylinder from deviating and rotating, thereby hitting the isolation sleeve 23, and even causing cracks in the isolation sleeve 23, causing corrosive liquid to enter the shell 16, and an adjustment assembly 6 for adjusting the inner magnetic cylinder is arranged on the inner wall of the isolation sleeve 23. The adjustment assembly 6 can prevent the inner magnetic cylinder from aggravating the wear of the isolation sleeve 23 due to the misalignment of the rotor, and will not only cause the corrosive liquid to leak from between the inner magnetic cylinder and the isolation sleeve 23, but also cause corrosion to the insulation components inside the fluorine-lined magnetic pump, and also cause huge vibrations in the fluorine-lined magnetic pump, thereby causing the temperature of the device to rise rapidly, which will cause damage to the drive motor 14.

[0034] The isolation component 2 includes two bearings 29 fixedly mounted on the inner wall of the outer shell 16, and a pump outer shaft 21 is rotatably mounted between the two bearings 29. The pump outer shaft 21 is fixedly connected to the coupling 15, and an outer magnetic rotor 22 is fixedly mounted on one end of the pump outer shaft 21. A pump shell 24 is inserted and connected to the isolation sleeve 23, and rubber rings 25 are respectively arranged between the isolation sleeve 23 and the pump shell 24 and the outer shell 16. The rubber ring 25 can offset a certain degree of vibration of the isolation sleeve 23 to prevent the isolation sleeve 23 from being damaged due to long-term vibration, thereby increasing the friction between the isolation sleeve 23 and the inner magnetic cylinder, and also preventing corrosive liquid from penetrating from the isolation sleeve 23 into the outer shell 16, thereby causing corrosion of the insulation device of the fluorine-lined magnetic pump. A rotating shaft 28 is rotatably mounted on the middle end of the isolation sleeve 23, and an inner magnetic rotor 26 is fixedly mounted on the axial side wall of the rotating shaft 28, and an impeller 27 is fixedly mounted on one end of the rotating shaft 28.

[0035] Specifically, first start the drive motor 14 so that the output end of the drive motor 14 drives the coupling 15 to rotate, thereby driving the pump outer shaft 21 and the outer magnetic rotor 22 to rotate, and utilizing the magnetic coupling effect to generate a magnetic field, so that the magnetic field penetrates the isolation sleeve 23 and is transmitted to the inner magnetic rotor 26, thereby driving the pump impeller 27 to rotate, thereby transporting the corrosive liquid. However, due to the high working intensity of the fluorine-lined magnetic pump, it is inevitable that the pump will vibrate. In order to avoid the rigid connection between the isolation sleeve 23 and the outer shell 16, the vibration will damage the isolation sleeve 23, and the corrosive liquid will enter the inner cavity of the fluorine-lined magnetic pump along the isolation sleeve 23, thereby causing corrosion of the insulation components inside the fluorine-lined magnetic pump, and causing the fluorine-lined magnetic pump to lose its insulation effect. The rubber ring 25 is made of corrosion-resistant elastic material, which can prevent the corrosive liquid from leaking from the junction to the outside of the fluorine-lined magnetic pump. The rubber ring 25 can also reduce the vibration range of the isolation sleeve 23, thereby protecting the isolation sleeve 23.

[0036] In order to solve the technical problem that the outer magnetic rotor 22 and the inner magnetic rotor 26 cannot be observed in time when the inner and outer magnetic cylinders are not aligned with each other during operation, Figure 3 and Figure 4 As shown, the following preferred technical solutions are provided: the detection component 3 includes a first laser sensor 31 fixedly arranged on the axial side wall of the outer magnetic rotor 22, a marking circle 32 is arranged on the side wall of the isolation sleeve 23, the first laser sensor 31 is aligned with the marking circle 32, when there is a deviation between the first laser sensor 31 and the marking circle 32, it indicates that the outer magnetic rotor 22 has a rotor misalignment phenomenon, and the first laser sensor 31 transmits a signal to the controller, and a second laser sensor 33 is arranged on the inner wall of the outer shell 16, the second laser sensor 33 is located on the side wall of the fluorine-lined magnetic pump, and is not within the magnetic force range of the outer magnetic rotor 22, the isolation sleeve 23 is made of transparent corrosion-resistant material, the second laser sensor 33 can pass through the isolation sleeve 23 to detect the inner magnetic rotor 26, and is located at the lower end of the second laser sensor 33. When the inner magnetic rotor 26 has a rotor misalignment, the second laser sensor 33 will transmit a signal to the controller.

[0037] The infrared ray of the second laser sensor 33 just contacts the outer wall of the inner magnetic rotor 26. When the inner magnetic rotor 26 deviates, the second laser sensor 33 can immediately detect this result and transmit this signal to the control box.

[0038] The first laser sensor 32 and the marking circle 31 are in the same position. When the first laser sensor 32 cannot mark the marking circle 31 , it indicates that the outer magnetic rotor 22 is offset.

[0039] Specifically, the first laser sensor 31 is started. Although the first laser sensor 31 rotates with the external magnetic rotor 22, the marking circle 32 is on the rotation radius of the first laser sensor 31. At this time, when the first laser sensor 31 cannot mark on the marking circle 32, it means that the external magnetic rotor 22 has a rotor misalignment. If it cannot be detected immediately at this time, the wear of the external magnetic rotor 22 and the bearing 29 will increase, and even cause the external magnetic rotor 22 and the isolation sleeve 23. At this time, not only will the pump vibrate violently, but the isolation sleeve 23 will even be cracked, so that the corrosive liquid enters the inner cavity of the fluorine-lined magnetic pump, thereby The corrosion of the thermal insulation components of the fluorine-lined magnetic pump causes the fluorine-lined magnetic pump to lose its thermal insulation effect. The second laser sensor 33 can detect the rotor misalignment of the inner magnetic rotor 26. When the second laser sensor 33 cannot detect the inner magnetic rotor 26 or cannot detect the inner wall of the outer shell 16, it means that the inner magnetic rotor 26 has a rotor misalignment. At this time, the friction with the isolation sleeve 23 will be aggravated, thereby increasing the force on the isolation sleeve 23, and the impeller 27 will contact the inner wall of the pump casing 24 when rotating, thereby causing damage to the impeller 27, making it impossible to effectively transport the liquid, and even causing a short circuit in the drive motor 14.

[0040] In order to solve the problem that the rotors of the inner and outer magnetic cylinders are not aligned during operation, and the corrosive liquid may leak out during maintenance, such as Figure 5-Figure 12 As shown, the following preferred technical solution is provided: the reset component 4 includes two first hydraulic pumps 41 fixedly mounted on the inner wall of the housing 16, the telescopic ends of the two first hydraulic pumps 41 are fixedly mounted with first arc-shaped clamps 42, a connecting plate 43 is fixedly mounted on the inner wall of the housing 16, a first tee 44 is fixedly arranged on the upper end of the connecting plate 43, a first oil delivery pipe 45 is arranged between the first tee 44 and the two first hydraulic pumps 41, a first oil inlet pipe 46 is arranged on the first tee 44, when the controller receives a signal, the oil pump is started, the oil pump enters the first tee 44 through the first oil inlet pipe 46, and then the oil is transported to the two first hydraulic pumps 41 through the first tee 44, so that the two first hydraulic pumps 41 start working.

[0041] The rolling assembly 5 includes a plurality of mounting grooves 51 provided on the first arc-shaped clamp 42 , on which a rotating shaft 52 is rotatably mounted, and on the axial side wall of the rotating shaft 52 a first roller 53 is fixedly mounted. The first roller 53 can effectively reduce the friction between the outer magnetic rotor 22 and the first arc-shaped clamp 42 .

[0042] The adjustment assembly 6 includes two second hydraulic pumps 61 fixedly arranged on the isolation sleeve 23, the telescopic ends of the two second hydraulic pumps 61 are fixedly installed with second arc clamps 62, a fixing plate 63 is fixedly installed on the inner wall of the isolation sleeve 23, a second tee 64 is fixedly installed on the lower end of the fixing plate 63, a second oil delivery pipe 65 is arranged between the second tee 64 and the second hydraulic pump 61, and a second oil inlet pipe 66 is arranged on the second tee 64. When the controller receives the signal, the oil pump is started, so that the oil pump enters the second tee 64 through the second oil inlet pipe 66, and then the oil is transported to the two second hydraulic pumps 61 through the second tee 64, so that the two second hydraulic pumps 61 start working.

[0043] The size of the first arc clamp 42 matches the size of the outer magnetic rotor 22, so that the first arc clamp 42 can well limit the outer magnetic rotor 22. The size of the second arc clamp 62 matches the size of the inner magnetic rotor 26, so that the second arc clamp 62 can well limit and adjust the inner magnetic rotor 26.

[0044] Specifically, when the first laser sensor 31 detects that the outer magnetic rotor 22 is misaligned, the first laser sensor 31 transmits a signal to the controller, so that the controller starts the oil pump, and the oil pump delivers the oil to the first tee 44 and the second tee 64 through the first oil inlet pipe 46 and the second oil inlet pipe 66, respectively. Subsequently, the oil is delivered from the first tee 44 and the second tee 64 through the first oil delivery pipe 45 and the second oil delivery pipe 65 to the two first hydraulic pumps 41 and the two second hydraulic pumps 61, respectively. At this time, the first hydraulic pump 41 and the second hydraulic pump 61 start to work, which drives the first arc clamp 42 and The second arc-shaped clamp 62 moves toward the middle, and at this time, the two first arc-shaped clamps 42 reset and adjust the outer magnetic rotor 22, and the two second arc-shaped clamps 62 reset and adjust the inner magnetic rotor 26. For the rotor misalignment between the inner magnetic rotor 26 and the outer magnetic rotor 22, the adjustment and reset of the inner and outer magnetic cylinders can be distinguished according to the signals of the first laser sensor 31 and the second laser sensor 33, so as to avoid the rotor misalignment in the working process. The first roller 53 can effectively reduce the friction between the inner and outer magnetic cylinders and the clamps, thereby indirectly reducing the working energy consumption.
