Description

Technical Field

[0001] The utility model relates to the technical field of reactors, in particular to a sealed stainless steel reactor. Background Art

[0002] A reactor, broadly defined as a container for physical or chemical reactions, achieves the heating, evaporation, cooling, and low-speed mixing required by the process through structural design and parameter configuration. Reactors are widely used in the petroleum, chemical, rubber, pesticide, dye, pharmaceutical, and food industries. When conducting chemical gas reactions, reactors require very high sealing properties.

[0003] Patent No. CN218573632U discloses a reactor sealing structure, comprising a reactor body and a reactor cover that is fastened to the reactor body, wherein the upper end of the reactor body is radially extended with a lower edge, and the reactor cover has an upper edge that is butt-jointed with the lower edge. The reactor sealing structure provided by the utility model solves the problem that the sealing ring of the existing reactor sealing structure will fall off after one use, making it impossible to reuse. However, since the internal pressure of the reactor increases when a chemical gas reaction or a gas-liquid mixed reaction is carried out, a large pressure difference exists between the inside and outside of the reactor. Moreover, some chemical reactions require a high pressure. When the pressure difference between the inside and outside of the reactor is large, the internal air pressure will push the cover upward, which will cause the connection between the sealing ring and the cover to become loose. Moreover, the compressed position of the sealing ring remains unchanged for a long time, which easily leads to a gap between the sealing ring and the cover, affecting the sealing effect.

[0021] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention. Example

[0022] See also Figure 1-5 The top of the sealing cover 2 is provided with a sealing groove 25, which is clamped with the top of the sealing ring 13. The sealing cover 2 is fixedly installed with a telescopic component on the bottom of the sealing cover 2. The telescopic component includes a mounting post 26 that is vertically slidably mounted on the bottom of the sealing cover 2. A telescopic extension rod 72 is mounted on the outer side of the mounting post 26. The top of the extension rod 72 can abut against the bottom of the sealing ring 13. The sealing cover 2 is locked with the sealing ring 11 by a locking component.

[0023] When in use, after the raw materials are placed in the reactor body 1, the sealing cover 2 is covered and the sealing cover 2 is locked by the locking assembly, so that the annular clamping groove 25 at the bottom of the sealing cover 2 is clamped with the sealing ring 13, and the extension rod 72 is in contact with the bottom of the sealing ring 13. During the chemical reaction of the reactor body 1, when the internal pressure increases, the sealing cover 2 and the mounting post 26 will be pushed upward. Under the action of the locking assembly, the sealing cover 2 remains stationary, but the mounting post 26 will be squeezed upward by the pressure, driving the extension rod 72 to move upward. At this time, the extension rod 72 will continuously apply upward pressure to the sealing ring 13. In this way, as the pressure in the reactor body 1 continues to increase, the sealing ring 13 is continuously squeezed, and its connection with the annular clamping groove 25 will be more compact. At the same time, when the sealing ring 13 is squeezed, its connection with the inner side of the annular groove 12 will also be more compact, thereby improving the sealing performance of the reactor body 1.

[0024] As a preferred embodiment, a buffer groove 210 is provided at the bottom of the sealing cover 2, and an elastic pad 29 is fixedly installed on the inner side of the buffer groove 210. When the mounting column 26 is pushed upward, the elastic pad 29 is squeezed to deform it, thereby increasing the activity space for the movement of the mounting column 26. At the same time, when the air pressure returns to normal, the elastic pad 29 can help the mounting column 26 to reset. The elastic pad 29 is fixedly connected to the mounting column 26, and a symmetrically distributed fixing rod 7 is fixedly installed on the outer side of the mounting column 26. An inner cavity 73 is provided on the inner side of the fixing rod 7. One end of the sliding rod 71 is slidably inserted into the inner side of the inner cavity 73, and the other end of the sliding rod 71 is fixedly connected to the extension rod 72. The top of the sealing cover 2 is fixedly plugged with a connecting pipe 28 The bottom end of the connecting tube 28 passes through the sealing cover 2 and is fixedly inserted into the interior of the fixed rod 7 and communicates with the inner cavity 73. Adjacent fixed rods 7 are connected to each other via the metal connecting tube 27. After the sealing cover 2 is installed, the connecting tube 28 is sealed and connected to the external gas supply device (the connection here is conventional and is not described in detail). External gas is introduced into the inner cavity 73 through the connecting tube 28. Gas is also introduced into multiple inner cavities 73 through the metal connecting tube 27. When the air pressure in the inner cavity 73 increases, it pushes the sliding rod 71 outward, driving the extension rod 72 to move and make it abut against the bottom of the sealing ring 13. Multiple extension rods 72 can simultaneously squeeze the sealing ring 13, further improving the sealing performance of the reactor body 1. When the reaction in the reactor is completed, the gas can be extracted through the connecting tube 28, and the sliding rod 71 will retract inward, driving the extension rod 72 to disengage from the sealing ring 13, and the sealing cover 2 can be removed smoothly.

[0025] As a preferred embodiment, a driving motor 3 is fixedly installed at the top center position of the sealing cover 2, and a feed pipe 4 and an air outlet pipe 5 are fixedly installed at the eccentric position of the top of the sealing cover 2. A control valve 51 is fixedly installed on the outside of the air outlet pipe 5. When a chemical or physical reaction is carried out, materials are added through the feed pipe 4, and the gas generated during the reaction is discharged through the air outlet pipe 5. The switch of the gas outlet pipe 5 is controlled by the control valve 51. Example

[0026] See also Figure 1-5 In this embodiment, the locking assembly includes an annular ring 21 fixedly installed at the bottom edge of the sealing cover 2, the inner side of the annular ring 21 abuts against the outer side of the sealing ring 11, and a plurality of symmetrically distributed slots 22 are provided on the outer side of the annular ring 21. A fastening block 23 is inserted and installed on the inner side of the slot 22, and the top of the fastening block 23 abuts against the bottom of the sealing ring 11. When installing the sealing cover 2, the fastening block 23 is inserted into the slot 22 and abutted against the bottom of the sealing ring 11, so that the sealing cover 2 can be locked on the sealing ring 11. Even if the air pressure of the reactor body 1 increases, it will not affect the sealing cover 2, and cooperate with the sealing ring 13 to further improve the sealing performance of the reactor body 1 during the reaction process.

[0027] As a preferred embodiment, a plurality of symmetrically distributed docking grooves 14 are provided at the bottom of the sealing ring 11, and the fastening blocks 23 are inserted and installed on the inner side of the docking grooves 14. The plurality of fastening blocks 23 are locked from multiple directions to improve the stability of the connection of the sealing cover 2.

[0028] As a preferred embodiment, the fastening block 23 extends to the outside of the sealing cover 2 on one side away from the slot 22 and is fixedly mounted with a push-pull rod 24. The fastening block 23 is driven by pushing or pulling the push-pull rod 24, making operation more convenient.

[0029] The output end of the drive motor 3 is rotatably connected to the inside of the sealing cover 2 and is fixedly installed with a center rod 6. The bottom end of the center rod 6 extends to the inside of the reactor body 1 and a plurality of stirring rods 61 are fixedly installed on the outside of the center rod 6 from top to bottom. The center rod 6 is inserted into the inner side of the mounting column 26 and the elastic pad 29. Starting the drive motor 3 drives the center rod 6 and the stirring rod 61 to rotate, which can stir the material in the reactor body 1 and make the reaction more uniform and thorough.

[0030] The working principle and usage process of the present invention are as follows: During the chemical reaction of the reactor body 1, when the internal pressure increases, the sealing cover 2 and the mounting post 26 are pushed upward. Under the action of the locking assembly, the sealing cover 2 remains stationary, but the mounting post 26 is pushed upward by the pressure, driving the extension rod 72 to move upward. At this time, the extension rod 72 continuously applies upward pressure to the sealing ring 13. As the pressure in the reactor body 1 continues to increase, the sealing ring 13 is continuously squeezed, and its connection with the annular clamping groove 25 becomes more compact. At the same time, as the sealing ring 13 is squeezed, its connection with the inner side of the annular groove 12 becomes more compact, thereby improving the sealing performance of the reactor body 1. When installing the sealing cover 2, the fastening block 23 is inserted into the slot 22 and abutted against the bottom of the sealing ring 11, and the sealing cover 2 is locked to the sealing ring 11. Even if the air pressure in the reactor body 1 increases, it will not affect the sealing cover 2. The sealing cover 2 and the sealing ring 13 further improve the sealing performance of the reactor body 1 during the reaction process.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
