Technical Field
[0001] This application relates to the field of mixing vessel technology, and in particular to a redundancy device for preventing overflow in a mixing vessel. Background Technology
[0002] In chemical production, stirred tanks are common and important equipment used for mixing materials. By adding materials into the stirred tank, the stirred tank is used to disperse and blend the materials, allowing them to react fully and thus improving work efficiency.
[0003] In existing stirred tanks, the discharge port is usually connected to an external pipeline, which leads to frequent replacement of the external pipeline. In order to ensure safe production, it is usually necessary to install corresponding protective measures at the discharge port of the stirred tank. The existing protective measures mainly include placing a collection box at the lower end of the connection between the liquid outlet pipe and the external pipeline. When replacing the pipeline, the collection box is used to catch the leakage, which is inconvenient. At the same time, different sealing rings need to be replaced because the external pipelines are of different lengths, which is also troublesome. Utility Model Content
[0004] The purpose of this application is to address the problems that existing protective measures mainly involve placing a collection box at the lower end of the connection between the outlet pipe and the external pipeline to catch the leaking liquid, which is inconvenient. In addition, the different lengths of the external pipelines require different sealing rings, which is also troublesome. This application provides a redundant anti-overflow device for a stirred tank.
[0005] To achieve the above objectives, this application specifically adopts the following technical solution:
[0006] An overflow prevention redundancy device for a mixing tank includes a discharge pipe with a valve installed on it. A fixing seat is bolted to the discharge pipe, and a connecting rod is fixed to the fixing seat. An mounting seat is fixed to the end of the connecting rod. A stainless steel corrugated pipe is inserted into the end of the discharge pipe, and a support rod is fixed to the stainless steel corrugated pipe. The support rod is fixedly connected to the connecting rod. An external pipe is inserted into the end of the stainless steel corrugated pipe away from the discharge pipe. Both ends of the stainless steel corrugated pipe are provided with sealing structures, and a locking structure is provided between the stainless steel corrugated pipe and the mounting seat.
[0007] By adopting the above technical solution, the sealing structure can reduce leakage during use. The sealing structure, combined with stainless steel bellows and locking structure, can reduce leakage during the replacement of external pipes. It is applicable to external pipes of different lengths and can reduce the number of times the sealing ring needs to be replaced.
[0008] Furthermore, the sealing structure includes sealing tubes fixed inside both ends of the stainless steel corrugated pipe, with abutment rings slidably sleeved on the sealing tubes, and sealing rings fixed to the sides of the abutment rings. The discharge pipe and the external pipe are respectively inserted into the sealing tubes at both ends of the stainless steel corrugated pipe and contact the sealing rings.
[0009] By adopting the above technical solution, the sealing structure can improve the sealing performance between the stainless steel corrugated pipe and the discharge pipe and external pipes, and reduce leakage.
[0010] Furthermore, an abutment spring is fixed to the side of the abutment ring, and the other end of the abutment spring is fixedly connected to the end of the sealing tube.
[0011] By adopting the above technical solution, the contact spring can improve the sealing effect between the sealing ring and the discharge pipe and external pipe.
[0012] Furthermore, the locking structure includes a guide rod rotatably connected to the mounting base, a movable sleeve slidably sleeved on the guide rod, a fixing bolt threadedly connected to the movable sleeve, the fixing bolt abutting against the guide rod, a fixing rod fixed to one end of the stainless steel corrugated pipe near the external pipe, the fixing rod being fixedly connected to the movable sleeve, and a connecting assembly provided between the mounting base and the guide rod.
[0013] By adopting the above technical solution, the position of the stainless steel corrugated pipe can be adjusted, which is suitable for external pipes of different lengths.
[0014] Furthermore, the connecting assembly includes a fixing block fixed on the guide rod, a fixing post threadedly connected to the fixing block, and a plurality of fixing holes provided on the mounting base, the fixing post slidingly extending into the fixing holes.
[0015] By adopting the above technical solution, the angle of the stainless steel corrugated pipe can be adjusted using the connecting components, making it suitable for external pipes at different angles.
[0016] Furthermore, a pressure relief valve is installed on the stainless steel bellows, and the pressure relief valve is an industrial-grade pneumatic pressure relief valve.
[0017] By adopting the above technical solution, when the internal pressure of the pipeline exceeds the preset value, the pressure relief valve opens to release gas, thereby improving the safety of the device.
[0018] Furthermore, a pressure sensor is installed inside the discharge pipe, and the pressure sensor is electrically connected to an external controller.
[0019] By adopting the above technical solution, the pressure sensor can monitor pressure changes inside the pipeline. When the pressure is too high, it transmits a signal to the controller to remind the operator to take appropriate measures.
[0020] Furthermore, a temperature sensor is installed inside the discharge pipe, and the temperature sensor is electrically connected to an external controller.
[0021] By adopting the above technical solution, the temperature sensor can monitor the temperature changes inside the pipeline, and when the temperature is too high, it transmits a signal to the controller to remind the operator to take appropriate measures.
[0022] In summary, this application includes at least one of the following beneficial effects:
[0023] 1. The sealing structure can improve the sealing effect between pipes and reduce the risk of leakage. When replacing the external pipe, loosen the fixing bolts to allow the stainless steel bellows to move freely.

During the replacement process, the retractable stainless steel bellows combined with the sealing structure can reduce leakage and reduce the need for replacing the sealing ring.
[0024] 2. When connecting stainless steel corrugated pipes to external pipelines, the position and angle of the ends of the stainless steel corrugated pipes can be adjusted to adapt to external pipelines of different positions, lengths, and angles, thereby increasing the range of applications of the device and making it more flexible.
[0025] 3. During the use of this device, when the internal pressure of the pipeline exceeds the preset value, the pressure relief valve will automatically open to release the excess gas, thereby reducing the impact of excessive pressure on the sealing ring on the seal and reducing leakage caused by excessive pressure, thus improving the safety of the device.

[0032] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0033] This application discloses a redundancy device for preventing overflow in a stirred tank.
[0034] Reference Figure 1 and Figure 2 An anti-overflow redundancy device for a mixing tank includes a discharge pipe 1, a valve installed on the discharge pipe 1, a fixing seat 2 fixed to the discharge pipe 1 by bolts, a connecting rod 21 fixed on the fixing seat 2, an mounting seat 3 fixed to the end of the connecting rod 21, a stainless steel corrugated pipe 5 inserted into the end of the discharge pipe 1, a support rod 6 fixed on the stainless steel corrugated pipe 5, the support rod 6 being fixedly connected to the connecting rod 21, an external pipe 7 inserted into the end of the stainless steel corrugated pipe 5 away from the discharge pipe 1, sealing structures provided at both ends of the stainless steel corrugated pipe 5, and a locking structure provided between the stainless steel corrugated pipe 5 and the mounting seat 3.
[0035] When installing the device, the fixing seat 2 is fitted onto the discharge pipe 1, and the discharge pipe 1 is inserted into the stainless steel corrugated pipe 5. The pipe is then sealed using a sealing structure. After sealing, the fixing seat 2 is fixed onto the discharge pipe 1 using bolts. Then, the position of the stainless steel corrugated pipe 5 is adjusted so that its other end is connected to the external pipe 7, allowing the external pipe 7 to be inserted into the stainless steel corrugated pipe 5. The pipe is then sealed using a sealing structure. After sealing, the position of the stainless steel corrugated pipe 5 is locked using a locking structure.
[0036] Reference Figure 2 and Figure 3 The sealing structure includes sealing tubes 8 fixed inside both ends of the stainless steel corrugated pipe 5, with abutment rings 10 slidably sleeved on the sealing tubes 8, and sealing rings 11 fixed on the sides of the abutment rings 10. The discharge pipe 1 and the external pipe 7 are respectively inserted into the sealing tubes 8 at both ends of the stainless steel corrugated pipe 5 and contact the sealing rings 11.
[0037] The contact ring 10 has a contact spring 9 fixed to its side, and the other end of the contact spring 9 is fixedly connected to the end of the sealing tube 8.
[0038] When the discharge pipe 1 and the external pipe 7 are inserted into the stainless steel corrugated pipe 5, they will be fitted onto the sealing pipe 8 and squeeze the sealing ring 11. The compression of the sealing ring 11 causes the contact ring 10 to be compressed against the contact spring 9. Through the spring reaction force, the sealing ring 11 can better contact the discharge pipe 1 and the external pipe 7, thereby improving the sealing effect and effectively reducing leakage problems.
[0039] Reference Figure 1 and Figure 4 The locking structure includes a guide rod 4 rotatably connected to the mounting base 3, a movable sleeve 13 slidably sleeved on the guide rod 4, a fixing bolt 14 threadedly connected to the movable sleeve 13, the fixing bolt 14 abutting against the guide rod 4, the side of the guide rod 4 in contact with the fixing bolt 14 being a rough surface, a fixing rod 12 fixed to one end of the stainless steel corrugated pipe 5 near the external pipe 7, the fixing rod 12 being fixedly connected to the movable sleeve 13, and a connecting component being provided between the mounting base 3 and the guide rod 4.
[0040] The connecting component includes a fixing block 16 fixed on the guide rod 4, a fixing post 17 threadedly connected to the fixing block 16, and a number of fixing holes 18 opened on the mounting base 3, with the fixing post 17 slidingly extending into the fixing hole 18.
[0041] When connecting the end of the stainless steel corrugated pipe 5 furthest from the discharge pipe 1 to the external pipe 7, adjust the position of the end of the stainless steel corrugated pipe 5 according to the position of the external pipe 7. During adjustment, first adjust the angle of the stainless steel corrugated pipe 5. First, turn the fixing post 17 upwards until it separates from the fixing hole 18. Then, move the guide rod 4 so that it moves the stainless steel corrugated pipe 5 on the mounting base 3. When the angle of the stainless steel corrugated pipe 5 corresponds to that of the external pipe 7, turn the fixing post 17 downwards and connect it to the corresponding fixing hole 18, thus completing the adjustment of the angle of the stainless steel corrugated pipe 5. Next, adjust the distance between the end of the stainless steel corrugated pipe 5 and the external pipe 7. During adjustment, first loosen the fixing bolt 14 so that it no longer abuts against the guide rod 4. Then move the stainless steel corrugated pipe 5 so that its end faces the external pipe 7. At this time, the fixing rod 12 moves along with the stainless steel corrugated pipe 5, causing the moving sleeve 13 to move on the guide rod 4. After the stainless steel corrugated pipe 5 is fitted onto the external pipe 7, and the sealing ring 11 abuts against the external pipe 7, tighten the fixing bolt 14 so that the fixing screw abuts against the guide rod 4, locking the position of the moving sleeve 13, thereby locking the position of the stainless steel corrugated pipe 5. By setting an adjustable stainless steel corrugated pipe 5, it can be adapted to external pipes 7 of different positions, lengths, and angles, thus improving the application range and flexibility of the device.
[0042] Reference Figure 1 and Figure 2 A pressure relief valve 15 is installed on the stainless steel bellows 5. The pressure relief valve 15 is an industrial-grade pneumatic pressure relief valve 15.
[0043] During the use of this device, when the internal pressure of the pipeline exceeds the preset value, the pressure relief valve 15 will automatically open to release the excess gas, thereby reducing the impact of excessive pressure on the sealing ring 11 on the seal when the pressure is too high, reducing leakage caused by excessive pressure, and thus improving the safety of the device.
[0044] Reference Figure 2 and Figure 3 A pressure sensor 19 is installed inside the discharge pipe 1, and the pressure sensor 19 is electrically connected to an external controller.
[0045] The discharge pipe 1 is equipped with a temperature sensor 20, which is electrically connected to an external controller.
[0046] When the reactor discharges material, pressure sensor 19 and temperature sensor 20 can monitor the pressure and temperature inside the discharge pipe 1. When the pressure or temperature is too high, a signal will be sent to the external controller, which will then control the buzzer and other alarm devices to sound an alarm, thereby reminding the staff to take appropriate measures and further improving the safety of the device.
[0047] Working principle: When installing this device, the fixing seat 2 is fitted onto the discharge pipe 1, and the discharge pipe 1 is inserted into the stainless steel corrugated pipe 5. At this time, the discharge pipe 1 will fit onto the sealing pipe 8 and compress the sealing ring 11. The compression of the sealing ring 11 causes the contact ring 10 to be compressed against the contact spring 9. Through the spring reaction force, the sealing ring 11 makes better contact with the discharge pipe 1, achieving a seal. Then, the fixing seat 2 is fixed onto the discharge pipe 1 with bolts. Then, the end of the stainless steel corrugated pipe 5 away from the discharge pipe 1 is connected to the external pipe 7. The position of the end of the stainless steel corrugated pipe 5 is adjusted according to the position of the external pipe 7. During adjustment, the angle of the stainless steel corrugated pipe 5 is adjusted first. First, the fixing column 17 is turned so that the fixing column 17 moves upward until it separates from the fixing hole 18. Then, the guide rod 4 is moved so that the guide rod 4 drives the stainless steel corrugated pipe 5 to move on the mounting seat 3. When the angle of the stainless steel corrugated pipe 5 corresponds to the external pipe 7, the fixing column 17 is turned so that the fixing column 1... 7. Move downwards and connect with the corresponding fixing hole 18 to complete the adjustment of the angle of the stainless steel corrugated pipe 5. Then adjust the distance between the end of the stainless steel corrugated pipe 5 and the external pipe 7. During adjustment, first tighten the fixing bolt 14 so that it no longer abuts against the guide rod 4. Then move the stainless steel corrugated pipe 5 so that its end faces the position of the external pipe 7. At this time, the fixing rod 12 moves with the stainless steel corrugated pipe 5 and drives the moving sleeve 13 to move on the guide rod 4. After the stainless steel corrugated pipe 5 is fitted on the external pipe 7, and the sealing ring 11 abuts against the external pipe 7, tighten the fixing bolt 14 so that the fixing screw abuts against the guide rod 4, locking the position of the moving sleeve 13, thereby locking the position of the stainless steel corrugated pipe 5. Then it can be put into use. When it is necessary to replace the external pipe 7, close the valve of the discharge pipe 1, then tighten the fixing bolt 14 to release the restriction on the stainless steel corrugated pipe 5, remove the old external pipe 7, and follow the above steps to connect the stainless steel corrugated pipe 5 and the external pipe 7.
