Description

Technical Field

[0001] The present application relates to the field of reactors, and in particular to a device for sampling reactants inside a reactor. Background Art

[0002] Resin generally refers to an organic polymer that hardens or melts when heated, tends to flow when softened by external forces, and is solid, semi-solid, or sometimes liquid at room temperature. Broadly speaking, any polymer compound that can be used as a raw material for plastic products can be called a resin.

[0003] Reactors are broadly understood as containers for physical or chemical reactions. Through structural design and parameter configuration of the container, the heating, evaporation, cooling and low-speed mixing functions required by the process are achieved. They are widely used in petroleum, chemical, rubber, pesticide, dye, medicine, and food. They are used to complete pressure vessels for processes such as vulcanization, nitration, hydrogenation, hydrocarbonization, polymerization, and condensation, such as reactors, reaction pots, decomposition pots, and polymerization kettles. They are generally made of carbon-manganese steel, stainless steel, zirconium, nickel-based (Hastelloy, Monel, Inconel) alloys and other composite materials.

[0004] During the processing of waterborne alkyd resin, sampling is required to monitor the reaction level. In the prior art, conventional reactors are typically opened for sampling. This complicated sampling method results in low sampling efficiency, hinders efficient sampling, significantly affects the interactions of raw materials within the reactor, and reduces the mixing effect. Utility Model Content

[0005] In order to improve the convenience for operators to sample the resin material in the reactor, the present application provides a device for sampling reactants inside the reactor.

[0006] The present application provides a device for sampling reactants inside a reactor using the following technical solutions:

[0007] A device for sampling reactants inside a reactor, comprising a sampling tube, one end of the sampling tube extending into the reactor body, and a sampling tube fixedly connected to the top of the end of the sampling tube extending out of the reactor, the sampling tube being in communication with the sampling tube;

[0008] A sampling screw is rotatably connected in the sampling tube, a servo motor is fixedly installed at the end of the sampling tube, and a drive shaft of the servo motor is fixedly connected to the sampling screw;

[0009] A first button and a second button are fixedly mounted on the frame of the reactor. The first button controls the servo motor to drive the sampling screw to rotate forward to output materials, and the second button controls the servo motor to drive the sampling screw to rotate reversely to return materials.

[0010] By adopting the above technical solution, during the actual production process, when the operator needs to sample the material in the reactor, the operator controls the servo motor to drive the sampling screw forward through the first button on the reactor frame. The spiral blades of the sampling screw can send the material in the reactor body through the sampling tube. The material sent through the sampling tube flows into the sampling tube, and the operator can use a tool to remove the material in the sampling tube. When the sampling is completed, the operator controls the servo motor to drive the sampling screw in reverse through the second button, and sends the sampling tube and the remaining material in the sampling tube back to the reactor, which can reduce material waste. By matching and using the sampling tube, servo motor, and sampling tube, the operator does not need to remove the reactor cover to take samples during the interruption of the reaction, which can effectively improve the convenience of sampling the reactor.

[0011] Preferably, the sampling tube is arranged to be inclined upward.

[0012] By adopting the above technical solution, the upwardly inclined arrangement of the sampling tube can reduce the situation where the material in the reactor body flows into the sampling tube through the sampling tube.

[0013] Preferably, the top of the sampling tube is integrally formed with a top plate, and the top plate is provided with a first sampling port;

[0014] A tube cover is rotatably mounted on the top of the sampling tube, and a second sampling port is penetrated through the top of the tube cover.

[0015] By adopting the above technical solution and setting the tube cover on the top of the sampling tube, the operator can rotate the tube cover during the normal reaction of the reactor so that the second sampling port is offset from the first sampling port, thereby sealing the sampling tube and reducing the occurrence of air in the external environment entering the reactor through the sampling tube and the sampling tube; when the operator needs to sample the material in the reactor, the tube cover can be rotated so that the second sampling port and the first sampling port coincide with each other, so that the operator can take out the material in the sampling tube by using tools.

[0016] Preferably, a positioning post is fixedly connected to the side wall of the sampling tube, and a sliding groove adapted to the positioning post is provided on the side wall of the tube cover;

[0017] A first limiting wall and a second limiting wall are respectively formed at both ends of the slide groove. When the positioning column abuts against the first limiting wall, the first sampling port and the second sampling port coincide with each other. When the positioning column abuts against the second limiting wall, the first sampling port and the second sampling port are staggered.

[0018] By adopting the above technical solution, through the setting of the positioning column and the sliding groove on the tube cover, when the operator rotates the tube cover, the positioning column can be abutted against the first limiting wall and the second limiting wall at both ends of the sliding groove, and the first sampling port can be completely exposed or completely closed, which can improve the convenience of the operator in rotating the tube cover.

[0019] Preferably, a socket for the positioning column to extend into is formed through the tube cover, and the socket is communicated with the sliding groove.

[0020] By adopting the above technical solution, the arrangement of the socket on the pipe cover can facilitate operators to remove or install the pipe cover.

[0021] Preferably, a rubber sealing ring is fixedly connected to the outer side wall of the sampling tube, and a ring groove adapted to the rubber sealing ring is opened on the inner side wall of the tube cover, and the rubber sealing ring is embedded in the ring groove.

[0022] By adopting the above technical solution, the rubber sealing ring can further improve the sealing performance of the connection between the tube cover and the sampling tube, and reduce the occurrence of external air entering the interior of the kettle through the sampling tube.

[0023] In summary, the present invention provides a device for sampling reactants inside a reactor, which has at least one of the following beneficial technical effects:

[0024] 1. When the operator needs to sample the material in the reactor, the operator controls the servo motor to drive the sampling screw forward through the first button on the reactor frame. The spiral blades of the sampling screw can send the material in the reactor body through the sampling tube. The material sent through the sampling tube flows into the sampling tube. The operator can use tools to take out the material in the sampling tube. When the sampling is completed, the operator controls the servo motor to drive the sampling screw in reverse through the second button, and sends the sampling tube and the remaining material in the sampling tube back to the reactor, which can reduce material waste. By matching and using the sampling tube, servo motor, and sampling tube, the operator does not need to remove the reactor cover to take samples during the interruption of the reaction, which can effectively improve the convenience of sampling the reactor.

[0025] 2. Through the setting of the tube cover on the top of the sampling tube, the operator can rotate the tube cover during the normal reaction of the reactor so that the second sampling port is offset from the first sampling port, thereby sealing the sampling tube and reducing the occurrence of air from the external environment entering the reactor through the sampling tube. When the operator needs to sample the material in the reactor, the tube cover can be rotated so that the second sampling port coincides with the first sampling port, so that the operator can use tools to remove the material in the sampling tube.

[0026] 3. The rubber sealing ring can further improve the sealing of the connection between the tube cover and the sampling tube, reducing the occurrence of external air entering the interior of the kettle through the sampling tube and the sampling tube. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The following is combined with Figure 1-3 This application is described in further detail.

[0032] Example

[0033] The present application discloses a device for sampling reactants inside a reactor. Figure 1-Figure 3 , including a sampling tube 1, one end of the sampling tube 1 extends into the kettle body of the reactor 5, and the top of the end of the sampling tube 1 extending out of the reactor 5 is fixedly connected to a sampling tube 2, and the sampling tube 2 is communicated with the sampling tube 1; a sampling screw 3 is rotatably connected in the sampling tube 1, and a servo motor 4 is fixedly installed at the end of the sampling tube 1, and the drive shaft of the servo motor 4 is fixedly connected to the sampling screw 3.

[0034] A first button 61 and a second button 62 are fixedly mounted on the frame 6 of the reactor 5. The first button 61 controls the servo motor 4 to drive the sampling screw 3 to rotate forward to output materials, and the second button 62 controls the servo motor 4 to drive the sampling screw 3 to rotate backward to return materials.

[0035] During the actual production process, when the operator needs to sample the material in the reactor 5, the operator controls the servo motor 4 to drive the sampling screw 3 to rotate forward through the first button 61 on the frame 6 of the reactor 5. The spiral blades of the sampling screw 3 can send the material in the reactor body of the reactor 5 out through the sampling tube 1. The material sent out through the sampling tube 1 flows into the sampling tube 2. The operator can take out the material in the sampling tube 2 through tools.

[0036] When sampling is complete, the operator controls the servo motor 4 via the second button 62 to reverse the sampling screw 3, returning the remaining material in the sampling tubes 2 and 1 to the reactor 5, thereby reducing material waste. By using the sampling tube 1, servo motor 4, and sampling tube 2 in conjunction with each other, the operator no longer needs to remove the reactor cover to perform sampling during a reaction interruption, effectively improving the convenience of sampling the reactor 5.

[0037] Reference Figure 1 In the embodiment of the present application, the sampling tube 1 is arranged to be tilted upward.

[0038] The upwardly inclined arrangement of the sampling tube 1 can reduce the occurrence of the material in the reactor body 5 flowing into the sampling tube 2 through the sampling tube 1 .

[0039] Reference Figure 2 The top of the sampling tube 2 is integrally formed with a top plate, on which a first sampling port 21 is opened; a tube cover 7 is rotatably installed on the top of the sampling tube 2, and a second sampling port 71 is opened through the top of the tube cover 7.

[0040] By installing a cap 7 on top of the sampling tube 2, the operator can rotate the cap 7 during the normal reaction in the reactor 5 so that the second sampling port 71 is offset from the first sampling port 21, thereby sealing the sampling tube 1 and reducing the risk of air from the outside environment entering the reactor 5 through the sampling tubes 2 and 1.

[0041] When the operator needs to sample the material in the reactor 5 , the tube cover 7 can be rotated to make the second sampling port 71 coincide with the second sampling port 71 , so that the operator can take out the material in the sampling tube 2 using a tool.

[0042] Reference Figure 2 and Figure 3 A positioning column 22 is fixedly connected to the side wall of the sampling tube 2, and a sliding groove 72 adapted to the positioning column 22 is opened on the side wall of the tube cover 7.

[0043] A first limiting wall and a second limiting wall are respectively formed at both ends of the slide groove 72. When the positioning column 22 abuts against the first limiting wall, the first sampling port 21 and the second sampling port 71 coincide with each other. When the positioning column 22 abuts against the second limiting wall, the first sampling port 21 and the second sampling port 71 are offset.

[0044] By setting the positioning post 22 and the slide groove 72 on the tube cover 7, when the operator rotates the tube cover 7, the positioning post 22 can be abutted against the first limiting wall and the second limiting wall at both ends of the slide groove 72, and the first sampling port 21 can be completely exposed or completely closed, which can improve the convenience of the operator in rotating the tube cover 7.

[0045] Reference Figure 3The pipe cover 7 is provided with a socket 73 for the positioning column 22 to extend therein, and the socket 73 is communicated with the chute 72. The provision of the socket 73 on the pipe cover 7 can facilitate the operator to disassemble or install the pipe cover 7.

[0046] Reference Figure 2 A rubber sealing ring 23 is fixedly connected to the outer wall of the sampling tube 2, and a ring groove 74 adapted to the rubber sealing ring 23 is opened on the inner wall of the tube cover 7, and the rubber sealing ring 23 is embedded in the ring groove 74.

[0047] The rubber sealing ring 23 can further improve the sealing performance of the connection between the tube cover 7 and the sampling tube 2, thereby reducing the risk of external air entering the interior of the kettle through the sampling tubes 2 and 1.

[0048] The implementation principle of the device for sampling reactants inside a reactor according to an embodiment of the present application is as follows: when an operator needs to sample the material in the reactor 5, the operator controls the servo motor 4 to drive the sampling screw 3 to rotate forward through the first button 61 on the frame 6 of the reactor 5. The spiral blades of the sampling screw 3 can send the material in the reactor body of the reactor 5 through the sampling tube 1. The material sent through the sampling tube 1 flows into the sampling tube 2. The operator can use a tool to take out the material in the sampling tube 2. When the sampling is completed, the operator controls the servo motor 4 to drive the sampling screw 3 to reverse through the second button 62, and sends the remaining material in the sampling tubes 2 and 1 back to the reactor 5, thereby reducing material waste. By matching and using the sampling tube 1, the servo motor 4, and the sampling tube 2, the operator does not need to remove the reactor cover for sampling during the interruption of the reaction, which can effectively improve the convenience of sampling the reactor 5.

[0049] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
