Description

Technical Field

[0001] The invention belongs to the technical field of glass processing, in particular to a glass-lined insertion tube. Background Art

[0002] Glass-lined insert tubes are widely used in chemical equipment due to their superior corrosion resistance, high strength and good heat resistance, replacing expensive special alloys and engineering plastic pipes. Glass-lined insert tubes are usually used in liquid-liquid mixing stirred tanks to transport liquid process materials, but in gas-liquid mixing stirred tanks, due to the fast gas flow rate, the gas flowing out of the insert tube outlet often leaves the reaction area before it has time to react, causing problems such as uneven reaction and short residence time, resulting in the working efficiency of the stirred tank not meeting expectations.

[0003] Due to the limitations of its manufacturing process, the glass-lined insertion tube cannot be equipped with an enamel distributor. In addition, due to the smooth enamel layer on its surface, the additionally installed distributor will always have problems such as falling off and corrosion. In addition, during processing, the molten glass raw material may penetrate into the gap between the distributor and the enamel layer, causing impurities to penetrate into the distributor, so improvements are needed. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present invention solves the technical problems by adopting a technical solution: a glass-lined insertion tube, comprising a transition glass tube, a slip-on flange is arranged on the top of the outer surface of the transition glass tube, and a gas outlet distributor is arranged at the bottom end of the transition glass tube;

[0005] An external sleeve is provided on the top of the gas outlet distributor, and a filling cushion tube is provided on the top of the inner wall of the external sleeve. After the gas outlet distributor is docked with the bottom end of the transition glass tube, the filling cushion tube is inserted into the gap between the external sleeve and the transition glass tube, and the inside of the filling cushion tube is inflated through the inflation ports on both sides to fill the gap between the external sleeve and the transition glass tube, and the inner wall of the filling cushion tube and the outer surface of the transition glass tube are pressed against each other;

[0006] The gas outlet distributor comprises a drainage cylinder shell, a diversion gas port is provided at the bottom of the inner cavity of the drainage cylinder shell, a traction slide is slidably connected to the top of the inner cavity of the drainage cylinder shell, a thrust spring is fixedly connected to the bottom end of the traction slide, and a docking device is provided on the top of the traction slide;

[0007] The docking device includes an outer ring cylinder shell, and both sides of the inner wall of the outer ring cylinder shell are rotatably connected with wall-attached arc plates, and the outer surface of the wall-attached arc plates is fixedly connected with an arc clamping plate. The inner arc clamping plate will be inserted into the interior of the transfer glass tube, and the outer arc clamping plate will cover the outside of the transfer glass tube. The arc clamping plates on both sides are simultaneously attached to the transfer glass tube to clamp the transfer glass tube, and both sides of the wall-attached arc plate are fixedly connected with arc spring belts.

[0008] Furthermore, the external sleeve includes a closed top tube, the upper part of the inner wall of the closed top tube is fixedly connected with a clustering push plate, the bottom of the inner cavity of the clustering push plate is evenly provided with arc-shaped push plates, the bottom end of the arc-shaped push plate is fixedly connected with a pressurizing push plate, the clustering push plate pushes the bottom arc-shaped push plate downward by pressurizing, so that the pressurizing push plate fits against the outer surface of the outer arc-shaped clamping plate, and pushes the outer arc-shaped clamping plate to squeeze the bottom of the outer surface of the transfer glass tube.

[0009] Furthermore, the side of the cluster push plate is fixedly connected to the inner wall of the external sleeve through a slot, the outer surface of the pressure push plate and the outer surface of the outer arc-shaped clamping plate are pressed against each other, and the bottom of the inner wall of the closed top tube is fixedly connected to the top of the outer surface of the drainage tube shell. An inflatable cushion tube is inserted into the upper part of the inner wall of the drainage tube shell. The inflatable cushion tube is an inner tube component similar to a filling cushion tube. After being inserted into the drainage tube shell, the inflatable cushion tube is inflated. At this time, the expanded upper part of the inflatable cushion tube will push the inner arc-shaped clamping plate toward the inner wall of the transfer glass tube. The lower part of the outer surface of the inflatable cushion tube and the inner wall of the drainage tube shell are pressed against each other, and the upper part of the outer surface of the inflatable cushion tube and the outer surface of the inner arc-shaped clamping plate are pressed against each other. The bottom end of the arc spring belt is fixedly connected to the inner cavity of the drainage tube shell. The lower part of the outer surface of the outer ring shell is fixedly connected to the top of the traction slide, the inner wall of the arc clamping plate is plugged into the bottom end of the transition glass tube, and the bottom of the outer surface of the arc clamping plate is rotatably connected to the side of the outer ring shell.

[0010] Furthermore, the slip-on flange includes an expansion outer disk, the top of the inner cavity of the expansion outer disk is evenly provided with vertical through tubes, the top of the vertical through tube is fixedly connected to the top of the intubation top disk, the axis of the inner cavity of the expansion outer disk is fixedly connected to the rubber inner membrane, and the inner wall of the rubber inner membrane is evenly provided with a spring pressure plate. The top of the intubation top disk is fixedly connected to the main inflation tube, the axis of the inner wall of the expansion outer disk is sleeved with the outer surface of the transition glass tube, one end of the spring pressure plate away from the rubber inner membrane is pressed against the outer surface of the transition glass tube, and the inner wall of the intubation top disk is fixedly connected to the top of the outer surface of the transition glass tube.

[0011] The beneficial effects of the present invention are as follows:

[0012] 1. After the gas outlet distributor of the device is installed on the transition glass tube, it can play the main connecting function through the internal arc-shaped clamping plate. When the transition glass tube is ventilated, the gas will be discharged directly from the diversion gas port through the inflatable cushion tube, so the problem of weakening the clamping effect of the arc-shaped clamping plate due to excessive pressure inside the gas outlet distributor will not occur, and it will not be adversely affected by the airflow. The closed top tube set on the upper part of the gas outlet distributor also prevents the penetration of molten glass raw materials through the replaceable filling cushion tube. Therefore, the assembled glass-lined insertion tube can not only work normally, but also has the function of disassembly and replacement at any time for detection and maintenance, to ensure that the ventilation work can proceed normally.

[0013] 2. The gas outlet distributor and the external sleeve of the device are independently arranged relative to the transition glass tube. Within a specific range, they can be installed on the bottom ends of transition glass tubes of different thicknesses. After adjustment by the internal control components, the arc-shaped clamping plates can play an effective clamping role, and the inflatable cushion tube can actively adjust the squeezing force when expanding and squeezing the inner arc-shaped clamping plates, thereby avoiding the problem that the arc-shaped clamping plates clamp the transition glass tubes too hard, causing the bottom of the transition glass tubes to break and be damaged.

[0014] 3. When the main inflation tube is inflated, the spring pressure plate will squeeze the outer surface of the transfer glass tube. On the one hand, the spring pressure plate can reinforce the connection effect between the slip-on flange and the transfer glass tube. On the other hand, the spring pressure plate can buffer the vibration force generated by the transfer glass tube when the air is ejected. When the main inflation tube is not working, the rubber inner membrane will rebound and reset. At this time, the slip-on flange can be easily removed from the transfer glass tube for assembly, replacement and maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The docking device 45 includes an outer ring cylinder shell 451, and both sides of the inner wall of the outer ring cylinder shell 451 are rotatably connected with the wall-attached arc plate 452, and the outer surface of the wall-attached arc plate 452 is fixedly connected with an arc clamping plate 453. The inner arc clamping plate 453 will be inserted into the interior of the transfer glass tube 1, and the outer arc clamping plate 453 will cover the outside of the transfer glass tube 1. The arc clamping plates 453 on both sides are simultaneously attached to the transfer glass tube 1 to clamp the transfer glass tube 1, and both sides of the wall-attached arc plate 452 are fixedly connected with arc spring belts 454.

[0027] The external sleeve 5 includes a closed top tube 51, and a clustering push plate 52 is fixedly connected to the upper part of the inner wall of the closed top tube 51. The bottom of the inner cavity of the clustering push plate 52 is evenly provided with arc-shaped push plates 53, and the bottom end of the arc-shaped push plate 53 is fixedly connected to a pressurizing push plate 54. The clustering push plate 52 pushes the bottom arc-shaped push plate 53 downward by pressurizing, so that the pressurizing push plate 54 fits against the outer surface of the outer arc-shaped clamping plate 453, and pushes the outer arc-shaped clamping plate 453 to squeeze the bottom of the outer surface of the transfer glass tube 1.

[0028] The side of the cluster push plate 52 is fixedly connected to the inner wall of the external sleeve 5 through a card slot, the outer surface of the pressure push plate 54 and the outer surface of the outer arc clamping plate 453 are pressed against each other, and the bottom of the inner wall of the closed top tube 51 is fixedly connected to the top of the outer surface of the drainage tube shell 41. The upper part of the inner wall of the drainage tube shell 41 is plugged with an inflatable cushion tube 7, which is an inner tube component similar to the filling cushion tube 6. After being inserted into the drainage tube shell 41, the inflatable cushion tube 7 is inflated. At this time, the expanded upper part of the inflatable cushion tube 7 will push the inner arc clamping plate 453 toward the inner wall of the transfer glass tube 1, the lower part of the outer surface of the inflatable cushion tube 7 and the inner wall of the drainage tube shell 41 are pressed against each other, the upper part of the outer surface of the inflatable cushion tube 7 and the outer surface of the inner arc clamping plate 453 are pressed against each other, and the bottom end of the arc spring belt 454 is fixedly connected to the inner cavity of the drainage tube shell 41. The lower part of the outer surface of the outer ring shell 451 is fixedly connected to the top of the traction slide 44, the inner wall of the arc clamping plate 453 is plugged into the bottom end of the transition glass tube 1, and the bottom of the outer surface of the arc clamping plate 453 is rotatably connected to the side of the outer ring shell 451.

[0029] First, the device is installed on the transition glass tube 1, and the slip-on flange 2 is put on the top of the transition glass tube 1. The drainage shell 41 is first inserted into the bottom end of the transition glass tube 1, so that the docking device 45 above the drainage shell 41 is docked with the bottom end of the transition glass tube 1, that is, the outer arc clamping plate 453 is uniformly located on the outside of the transition glass tube 1, and the inner arc clamping plate 453 is uniformly located inside the transition glass tube 1. When the operator is subjected to obvious pressure, it represents that the traction slide 44 squeezes the thrust spring 42, that is, the outer surface of the outer ring shell 451 and the bottom end of the transition glass tube 1 are squeezed against each other, and the inner arc clamping plate 453 is completely inserted into the interior of the transition glass tube 1.

[0030] After the gas outlet distributor 4 is installed, slide the external sleeve 5 along the outer surface of the drainage tube shell 41 until the bottom end of the closed top tube 51 is docked with the top end of the drainage tube shell 41. At this time, the clustering push plate 52 on the inner wall pushes the pressure push plate 54 through the arc push plate 53. By utilizing the thrust of the pressure push plate 54, the outer arc clamping plate 453 is tightly fitted to the outer surface of the transition glass tube 1. Then, install the filling gasket 6 in the gap between the external sleeve 5 and the transition glass tube 1, inflate the filling gasket 6 to make it expand, and then clamp the external sleeve 5.

[0031] Finally, the air-filled cushion tube 7 filling the inner wall of the drainage tube shell 41 is also inflated and pressurized through the diversion air port 43, so that the air-filled cushion tube 7 expands, squeezing the inner arc-shaped clamping plate 453 to shift in the direction of fitting the inner wall of the transition glass tube 1. At this time, the arc-shaped clamping plates 453 on both sides clamp the bottom end of the transition glass tube 1, completing the installation of the gas outlet distributor 4 and the transition glass tube 1.

[0032] After the main inflation tube 3 is docked with the expansion outer disk 21, the glass-lined material inside the container is inflated through the adapter glass tube 1. The airflow enters the container through the adapter glass tube 1 and the drainage tube shell 41, and the inflation work at different angles is achieved through the dispersed diversion air ports 43 on the drainage tube shell 41.

[0033] Example 2, please refer to Figure 1-Figure 6 The present invention provides a technical solution: on the basis of the first embodiment, the slip-on flange 2 comprises an expansion outer disk 21, the top of the inner cavity of the expansion outer disk 21 is evenly provided with a vertical through tube 22, the top of the vertical through tube 22 is fixedly connected with a tube top disk 23, the axis of the inner cavity of the expansion outer disk 21 is fixedly connected with a rubber inner membrane 24, and the inner wall of the rubber inner membrane 24 is evenly provided with a spring pressure plate 25. The top of the tube top disk 23 is fixedly connected with a main inflation tube 3, the axis of the inner wall of the expansion outer disk 21 is sleeved with the outer surface of the transition glass tube 1, the end of the spring pressure plate 25 away from the rubber inner membrane 24 is pressed against the outer surface of the transition glass tube 1, and the inner wall of the tube top disk 23 is fixedly connected with the top of the outer surface of the transition glass tube 1.

[0034] When the main inflation tube 3 is inflated, the interior of the insertion tube top plate 23 will also be inflated through the vertical through tube 22. At this time, the internal pressure of the insertion tube top plate 23 increases, and the rubber inner membrane 24 located at the axial center will expand toward the side close to the transfer glass tube 1 due to the effect of air pressure, and will be squeezed against the outer surface of the transfer glass tube 1 through the spring pressure plate 25. On the one hand, the spring pressure plate 25 can be used to reinforce the connection effect between the slip-on flange 2 and the transfer glass tube 1, and on the other hand, the spring pressure plate 25 can be used to buffer the vibration force generated by the transfer glass tube 1 when the jet is ejected. When the main inflation tube 3 is not working, the rubber inner membrane 24 will rebound and reset. At this time, the slip-on flange 2 can be easily removed from the transfer glass tube 1 for assembly, replacement and maintenance.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention.
