Description

Technical Field

[0001] The utility model relates to the technical field of reactors, in particular to a sealing device for a reactor. Background Art

[0002] The production of titanium sponge by the magnesium thermal method is carried out in a closed reaction tank, and the reduction-distillation in the production process needs to be carried out under high temperature and vacuum. However, leakage is prone to occur in actual production, allowing air to enter the reactor, thereby increasing the nitrogen content in the titanium sponge and affecting the product quality. Therefore, the production of titanium sponge by the magnesium thermal method has very high requirements on the air tightness of the reaction tank of the main equipment.

[0003] The main factors affecting the sealing performance of the reactor are: (1) Bolt preload: Appropriate bolt preload can ensure that the gasket can maintain a certain sealing pressure ratio during operation. Excessive preload will crush or squeeze the gasket, thereby destroying the sealing device of the reactor. (2) Sealing surface characteristics: The flange sealing surface mainly includes flat surface, concave and convex surface and tongue and groove surface. Flat sealing has the advantages of simple structure, easy processing and easy anti-corrosion lining. However, the contact area between the flat sealing surface and the gasket is large. The size of the preload directly affects the sealing effect of the sealing gasket. (3) Sealing performance of the sealing gasket: The sealing gasket is the most critical link affecting the sealing performance of the joint. Appropriate gasket material requirements Under the action of appropriate pre-tightening force, the gasket can produce the necessary elastic deformation without being crushed or squeezed out. During operation, the distance between the flange sealing surfaces is enlarged, and the gasket material should have sufficient resilience to make the gasket surface contact with the flange sealing surface to continue to maintain good sealing performance. However, in the existing technology, it is impossible to adjust the bolt pre-tightening force according to the performance of the sealing gasket. The current method is to tighten the bolts based on past experience so that the pre-tightening force meets the performance of the sealing gasket. However, this method requires experienced personnel to install it, and secondly, there may be a situation where the bolt pre-tightening force is not compatible with the performance of the sealing gasket, which ultimately affects the sealing of the reactor. Summary of the invention

[0004] In order to make up for the above deficiencies, the utility model provides a sealing device for a reactor.

[0005] The utility model is achieved in this way:

[0006] A sealing device for a reactor comprises a sealing mechanism and an adjusting mechanism, wherein the sealing mechanism comprises a pipeline, flanges are installed at both ends of the pipeline, installation cavities are opened on the sides of the flanges away from each other, pressure sensors are installed inside the installation cavities, sealing gaskets are installed inside the installation cavities, and the sealing gaskets and pressure sensors are fitted together, the adjusting mechanism comprises a plurality of machine bases, and a micro motor is installed on the top of the machine base, a plurality of threaded rods are rotatably connected inside the flanges, and one of the threaded rods is transmission-connected to the output end of the micro motor, and a plurality of the threaded rods are transmission-connected, nuts are bite-connected on the outside of the threaded rods, and limit plates are symmetrically installed on the outside of the nuts, a plurality of pairs of limit rods are installed on one side of the flange, and the limit plates slide on the outside of the limit rods.

[0007] The beneficial effect of adopting the above further scheme is that after the micromotor is started, it can drive one of the threaded rods to rotate. Since the three groups of threaded rods are transmission connected, the three groups of threaded rods will rotate synchronously, and under the action of the limit rod, the nut can make a linear motion. When in use, the three groups of threaded rods of the flange at one end are passed through the fixing holes of the flange of the reactor, and the three groups of threaded rods of the flange at the other end are passed through the fixing holes of the flange of the feed pipe. When the nut moves forward, the flanges can be squeezed against each other to fix the flanges together. At this time, the sealing gasket will squeeze the pressure sensor. When the pressure sensor measures that the pressure it is subjected to reaches the set value, it will be fed back to the control end. The control end will shut down the micromotor at this time, so that the state of the sealing gasket reaches the best, so that the sealing device can achieve the best sealing state.

[0008] Furthermore, the number of the machine base and the micro motor is set to one pair, the number of the threaded rod and the pressure sensor is set to three pairs, and the number of the limit rods is set to six pairs.

[0009] Furthermore, one end of the threaded rod passes through the flange.

[0010] The beneficial effect of adopting the above further solution is that this condition limits the length of the threaded rod, so that the threaded rod can pass through the fixing holes of the flange of the reactor and the fixing holes of the flange of the feed pipe.

[0011] Furthermore, the micro motor and the pressure sensor are both electrically connected to the PLC controller.

[0012] The beneficial effect of adopting the above further solution is that the PLC controller can automatically control the micro motor and the pressure sensor.

[0013] Furthermore, gears are installed on the outer sides of the threaded rods, and a gear ring is symmetrically rotatably connected to the outer sides of the pipes, and the gears and the gear ring are meshingly connected.

[0014] The beneficial effect of adopting the above further solution is that when the threaded rod with the gear rotates, it can drive the gear ring to rotate, thereby rotating the other two gears, ultimately achieving the purpose of synchronous rotation of the three sets of threaded rods, and the three sets of nuts can improve the reliability of fixation.

[0015] Furthermore, the specifications of the gears are consistent.

[0016] The beneficial effect of adopting the above further solution is that the rotation speeds of the three groups of threaded rods are made consistent.

[0017] Furthermore, the outer side of the pipe is symmetrically provided with limiting grooves, and the inner ring of the gear ring is installed with a limiting ring, and the limiting ring rotates in the limiting groove.

[0018] The beneficial effect of adopting the above further solution is that the use of the limiting groove and the limiting ring can enable the gear ring to maintain stable rotation without deviation.

[0019] Furthermore, the sealing gasket is made of chloroprene rubber.

[0020] The beneficial effect of the utility model is as follows: the utility model obtains a sealing device of a reactor through the above design. After the micro motor is started, it can drive one of the threaded rods to rotate. Because the three groups of threaded rods are transmission connected, the three groups of threaded rods will rotate synchronously, and under the action of the limit rod, the nut can make a linear motion. When in use, the three groups of threaded rods of the flange at one end are passed through the fixing holes of the flange of the reactor, and the three groups of threaded rods of the flange at the other end are passed through the fixing holes of the flange of the feed pipe. When the nut moves forward, the flanges can be squeezed against each other, so as to fix the flanges together. At this time, the sealing gasket will squeeze the pressure sensor. After the pressure sensor measures that the pressure it is subjected to reaches the set value, it will be fed back to the control end. The control end will shut down the micro motor at this time, so that the state of the sealing gasket is optimal, so that the sealing device can achieve the best sealing state.

[0029] Embodiment 1 of the sealing device of a reactor of the utility model

[0030] The utility model provides the following technical solutions: Figure 1 to Figure 4, including a sealing mechanism 100 and an adjusting mechanism 200, the sealing mechanism 100 includes a pipe 1001, both ends of the pipe 1001 are installed with flanges 1002, the flanges 1002 are provided with mounting cavities 1004 on the sides away from each other, the mounting cavities 1004 are installed with pressure sensors 1005, the mounting cavities 1004 are installed with sealing gaskets 1003, and the sealing gaskets 1003 and the pressure sensors 1005 are fitted, and the adjusting mechanism 200 includes a plurality of machine bases 2002 , and a micro motor 2003 is installed on the top of the base 2002, and a plurality of threaded rods 2004 are rotatably connected inside the flange 1002, and one of the threaded rods 2004 is transmission-connected to the output end of the micro motor 2003, and a plurality of threaded rods 2004 are transmission-connected, and the outer sides of the threaded rods 2004 are bite-connected with nuts 2006, and the outer sides of the nuts 2006 are symmetrically installed with limit plates 2008, and a plurality of pairs of limit rods 2007 are installed on one side of the flange 1002, and the limit plates 2 008 slides on the outside of the limit rod 2007. After the micro motor 2003 is started, it can drive one of the threaded rods 2004 to rotate. Because the three groups of threaded rods 2004 are transmission connected, the three groups of threaded rods 2004 will rotate synchronously, and under the action of the limit rod 2007, the nut 2006 can make a linear motion. When in use, the three groups of threaded rods 2004 of the flange 1002 at one end are inserted through the fixing holes of the flange of the reactor, and the three groups of threaded rods 2004 of the flange 1002 at the other end are inserted through the fixing holes of the flange of the feed pipe. When the nut 2006 moves forward, the flanges 1002 can be squeezed against each other, so as to fix the flanges 1002 together. At this time, the sealing gasket 1003 will squeeze the pressure sensor 1005. After the pressure sensor 1005 measures that the pressure it is subjected to reaches the set value, it will be fed back to the control end. The control end will then shut down the micro motor 2003, so that the state of the sealing gasket 1003 is optimal, so that the sealing device can achieve the best sealing state.

[0031] Embodiment 2 of the sealing device of a reactor of the utility model

[0033] Embodiment 3 of the sealing device of a reactor of the utility model

[0034] Reference Figure 1 to Figure 4Specifically, gears 2005 are installed on the outer sides of the threaded rods 2004, and the outer sides of the pipes 1001 are symmetrically connected to the gear rings 2001 for rotation, and the gears 2005 and the gear rings 2001 are meshingly connected. When the threaded rods 2004 with the gears 2005 rotate, the gear rings 2001 can be driven to rotate, thereby rotating the other two gears 2005, and finally achieving the purpose of synchronous rotation of the three groups of threaded rods 2004, and the three groups of nuts 2006 can improve the reliability of the fixation. The specifications of the gears 2005 are consistent, so that the rotation speeds of the three groups of threaded rods 2004 are consistent. Limiting grooves are symmetrically provided on the outer sides of the pipes 1001, and limiting rings are installed on the inner rings of the gear rings 2001. The limiting rings rotate in the limiting grooves. The use of the limiting grooves and the limiting rings can keep the gear rings 2001 rotating stably without deviation.

[0035] Specifically, the working principle of the sealing device of the reactor is as follows: when in use, the three groups of threaded rods 2004 of the flange 1002 at one end are passed through the fixing holes of the flange of the reactor, and the three groups of threaded rods 2004 of the flange 1002 at the other end are passed through the fixing holes of the flange of the feed pipe, and then a pair of micro motors 2003 are started. After the micro motor 2003 is started, it can drive one of the threaded rods 2004 to rotate. Since the three groups of threaded rods 2004 are transmission-connected, the three groups of threaded rods 2004 will rotate synchronously, and under the action of the limit rod 2007, the nut 2006 can make a linear motion, so that the flanges 1002 are squeezed against each other, so as to fix the flanges 1002 together. At this time, the sealing gasket 1003 will squeeze the pressure sensor 1005. After the pressure sensor 1005 measures that the pressure it is subjected to reaches the set value, it will be fed back to the control end. The control end will then shut down the micro motor 2003, so that the state of the sealing gasket 1003 is optimal, so that the sealing device can achieve the best sealing state.
