Description

Technical Field

[0001] The invention relates to the technical field of magnetic sealing transmission devices, in particular to a magnetic sealing transmission device for easily sublimated materials. Background Art

[0002] The magnetic seal transmission device uses a magnetic coupler to connect the motor to the stirrer of the reactor, and transmits power through the magnetic field, realizing the function of transmitting power without mechanical contact. This device can not only effectively improve the sealing performance and avoid the problems of easy wear and leakage of traditional mechanical seals, but also reduce energy consumption, extend the service life of equipment, and improve production efficiency.

[0003] In the current magnetic sealing transmission device, when the outer magnet transmits torque through the input shaft, the eddy current loss between the inner and outer magnets will generate a large amount of heat. The high temperature environment will accelerate the aging of the outer and inner magnets and reduce their magnetic properties. At the same time, it will also increase the heat generation inside the magnet. At present, fins are often added to the outside of the outer magnet to dissipate heat to the outside of the outer magnet. However, the inner magnet arranged inside the outer magnet will still have demagnetization problems after being used in a high temperature environment for a long time. In addition, when the existing magnetic sealing transmission device is used for easily sublimated materials, the easily sublimated materials can easily enter the magnetic sealing transmission device through the connection of the agitator shaft and sublimate on the inner magnet, which can easily affect the normal operation of the inner magnet. To address the above problems, we propose a magnetic sealing transmission device for easily sublimated materials. Summary of the invention

The purpose of the sealing cover 5 is to realize a static sealing cavity, thereby effectively preventing leakage. Due to the existence of the sealing cover 5, the stirring part will not extend out of the reactor body when rotating, thereby avoiding the leakage problem that cannot be overcome by the traditional packing sealing method, and also includes:

[0029] The support platform 6 is fixedly connected to the connecting flange 1 by bolts, and an adjusting cavity is provided inside the support platform 6, and the adjusting cavity is used to install the filtered air cooling pipe 12;

[0030] An inner magnetic steel cooling system, the inner magnetic steel cooling system comprises a cooling mechanism 1 and a heat insulation mechanism, the cooling mechanism 1 is arranged around the inner magnetic steel 3 and is used to cool the inner magnetic steel 3, and the heat insulation mechanism is used to reduce the heat exchange between the cooling mechanism 1 and the reactor; and

[0031] Material filtration system, the material filtration system is arranged in the regulating chamber, the material filtration system includes a connecting mechanism, a second cooling mechanism, a filtering mechanism and a recovery mechanism, the connecting mechanism is used to control the exhaust gas to enter the regulating chamber according to the air pressure, the second cooling mechanism is used to cool the exhaust gas entering the regulating chamber, the filtering mechanism is used to filter the cooled exhaust gas, and the recovery mechanism is used to recover the material on the filtering mechanism.

[0032] The cooling mechanism 1 includes fins 7 and a cooling pipe 8. The fins 7 are arranged at the bottom of the inner magnetic steel 3 and are used to blow cold air to the upper end of the inner magnetic steel 3, thereby increasing the heat dissipation effect of the inner magnetic steel 3. The cooling pipe 8 is arranged at the bottom of the inner magnetic steel 3. The cooling pipe 8 is used to dissipate the heat of the inner magnetic steel 3 through liquid cooling. As shown in the figure of the specification, the circulation port 801 of the cooling pipe 8 is arranged on the outside of the connecting flange 1.

[0033] A supporting flange 9 is connected to the bottom of the supporting platform 6. The supporting platform 6 and the supporting flange 9 are both installed in the groove on the reactor body. The heat insulation mechanism includes a heat insulation board 10. The heat insulation board 10 is a hollow structure. The heat insulation board 10 is arranged on the supporting flange 9 and is used to reduce the heat exchange between the cooling pipe 8 and the reactor, thereby preventing the ambient temperature from overheating and affecting the cooling effect of the filter gas cooling pipe 12.

[0034] The connecting mechanism includes a gas lift valve 11. The gas lift valve 11 is a prior art that can be adaptively selected according to the physical properties of different materials. The gas lift valve 11 is arranged through the insulation board 10 and the support flange 9. The gas lift valve 11 is used to control the exhaust gas to enter the regulating chamber according to the air pressure. When the pressure in the reactor is too high, the gas lift valve 11 will be lifted up to allow part of the exhaust gas to enter the regulating chamber.

[0035] The second cooling mechanism comprises a filtered air cooling pipe 12, which is arranged around the regulating chamber and is used to cool the exhaust gas entering the regulating chamber.

[0036] The filtering mechanism includes a fixing frame 13, a filter screen 14 and an industrial sponge 15. The fixing frame 13 is used to install the filter screen 14 and the industrial sponge 15. The fixing frame 13 is fixedly connected to the support platform 6 by bolts. The industrial sponge 15 is arranged on the fixing frame 13. The industrial sponge 15 is used to block the easily desublimated materials so as to prevent the easily desublimated materials from desublimating on the inner magnetic steel 3. As shown in the attached figure of the specification, the filter screen 14 is arranged below the industrial sponge 15. The filter screen 14 is used to block the exhaust gas of the easily desublimated materials so that part of the easily desublimated materials is desublimated and attached to the filter screen 14.

[0037] The filter screen 14 is provided with three layers, and as shown in the drawings of the specification, the three layers of the filter screen 14 are connected to each other.

[0038] The recycling mechanism includes a mounting block 16, a motion block 17, a motion gear 18, a motion motor 19, a scraping rod 20 and a storage box 21. The mounting block 16 is arranged on the support platform 6. The mounting block 16 is used to install the motion gear 18. A gear groove is opened inside the mounting block 16. The gear groove is used to cooperate with the motion gear 18 so that the motion gear 18 can only move along the gear groove. The motion gear 18 is arranged on the motion block 17 and meshes with the gear groove. The motion motor 19 is used to drive the motion gear 18 to rotate. The motion motor 19 is a DC motor that can output in both directions. The gear at the output end of the motion motor 19 is meshed with the motion gear 18. The scraping rod 20 is arranged in the moving groove. The scraping rod 20 is fitted on the filter screen 14 and is used to scrape the material attached to the filter screen 14. The motion motor 19 drives the motion block 17 to move to drive the scraping rod 20 to push the material attached to the filter screen 14 into the storage box 21.

[0039] Working principle: When in use, coolant is continuously pumped into the cooling tube 8 through the circulation port 801 to cool the inner magnetic steel 3. At the same time, when the inner magnetic steel 3 rotates, the fins 7 at the bottom of the inner magnetic steel 3 will also blow the cooled air of the cooling tube 8 to the upper end of the inner magnetic steel 3, thereby achieving comprehensive cooling of the inner magnetic steel 3. When the air pressure in the reactor reaches the opening value of the gas lift valve 11, the gas lift valve 11 will open. At this time, part of the exhaust gas will enter the regulating chamber and after being cooled by the filtered air cooling tube 12, the exhaust gas will reach the filter 14. After that, a small part of the material will be condensed on the filter 14, and most of the remaining exhaust gas will be condensed on the industrial sponge 15. After a period of use, the motion motor 19 is controlled to drive the motion gear 18 to rotate, thereby driving the scraper rod 20 to push the condensed material attached to the filter 14 into the storage box 21, so that the material attached to the filter 14 can be cleaned and recovered.
