Description

Technical Field

[0001] This utility model relates to the field of stirring device technology, and in particular to a stirring protection barrier. Background Technology

[0002] A stirring protection barrier refers to a device, substance, and related measures set up to achieve specific protective functions during liquid stirring. Its function is to protect the liquid itself and the stirring equipment from the adverse effects of the stirring process by means of isolation, buffering, and stabilization, such as preventing equipment corrosion, reducing the mixing of impurities, controlling liquid evaporation, and maintaining liquid stability. Under the vigorous stirring of the stirring device, the liquid in the tank is mixed more thoroughly.

[0003] A search revealed Chinese Patent Publication No. CN213611172U, which discloses a mixing device for road noise barrier vibration-damping and sound-absorbing mixtures that is easy to clean. The device includes a main body comprising a cylindrical shell. A motor is fixedly mounted at the top of the cylindrical shell, and a conveyor belt is located at the bottom of the motor. A main mixing shaft is fixedly mounted on one side of the conveyor belt via rollers, and the main mixing shaft extends into the interior of the cylindrical shell through a through-groove. This invention, by incorporating a main mixing shaft, a cleaning scraper, and a cleaning brush, solves the problem of existing vibration-damping and sound-absorbing mixture mixing devices being difficult to clean. The deposits on both sides of its inner wall often cause trouble for the workers, not only reducing the quality of the shock-absorbing and sound-absorbing mixture, but also increasing the workload of the workers. Further, the bottom of the device cylinder is arc-shaped, which facilitates the discharge of materials inside the device cylinder and increases the practicality of the device. However, in the existing stirring protection barrier, the stirring device is installed on the outer wall of the reactor. The stirring rotation drives the rotation of the rotating structure inside the reactor. This stirring method cannot prevent gas from entering the reactor, which can easily cause oxidation and deterioration of the materials inside the reactor and increase the risk of oxygen entering the reactor.

An index 22 is fixedly connected to the front of the outer wall of the box 3. A bolt 23 is threadedly connected to the top of the outer wall of the sealing cover 6.

[0044] Specifically, the connecting pipe 18 on the rear side of the top of the reactor 1 can be used to connect to external equipment to realize the functions of material conveying and gas inlet and outlet, so as to meet the needs of material addition or product discharge during the reaction process; the thermometer 19 on the right side of the top is used to monitor the temperature inside the reactor 1 in real time, so as to control the reaction process and adjust the reaction conditions according to the temperature; the support frame 20 on the top of the outer wall of the reactor 1, together with bolt 21, can fix and install related components or equipment, such as fixing part of the structure of the stirring device to ensure its stable operation; the directional indicator 22 on the front side of the outer wall of the box 3 can be used as a position or direction mark to help equipment installation, operation and maintenance personnel quickly identify the location; the bolt 23 on the sealing cover 6 is used to tighten the sealing cover 6, ensure the sealing of the box 3, prevent gas leakage, maintain internal pressure stability and gas environment, and provide a guarantee for the normal operation of the reactor 1.

[0045] Working Principle: This stirring protection barrier mainly consists of components such as the reactor 1 and the box 3. It aims to provide protection and auxiliary functions for the stirring process within the reactor 1, and plays a role in temperature control and gas handling within the reactor 1. The inlet channel 4 and outlet channel 5 are respectively located on the left and right sides of the box 3. The inlet channel 4 introduces steam into the box 3, and the gas exits through the outlet channel 5. This steam inlet and outlet configuration enables gas circulation and directional flow within the box 3. The sealing cover 6 is fixed to the top of the box 3 by screw 7. When screw 7 is tightened, the sealing cover 6 fits tightly against the box 3, providing a good seal and preventing gas leakage. This ensures gas flows within the designated channels, maintaining stable internal pressure and gas environment. The fins 8 fixedly connected to the rear side of the outer wall of the box 3 and the conduit 9 penetrating the middle of its inner wall together constitute a heat dissipation structure. When the temperature inside the box 3 rises, heat is transferred to the fins 8, causing the fins 8 to enlarge. The cooling medium flows in the conduit 9 to absorb heat from the fins 8 and convert steam into condensate, thereby dissipating the heat inside the box 3 and regulating the temperature. This prevents the stirring reaction or equipment performance inside the reactor 1 from being affected by excessively high temperatures. The motor 10 is fixed to the top of the box 3. After being powered on, the output end of the motor 10 drives the rotating shaft 11 to rotate. The rotating shaft 11 passes through the middle of the inner wall of the box 3. Its rotation will drive the stirring paddle inside the box 3 to rotate, thereby realizing the stirring, mixing and accelerated flow of the gas inside the box 3, further improving the gas processing efficiency. This interaction provides better assistance and protection for the stirring process inside the reactor 1. The box 3 is installed on the outer wall of the reactor 1. The rotating shaft 11 of the drive component is rotatably connected to the box 3. The side wall of the box 3 is provided with an air inlet and an air outlet. Steam is passed into the air inlet and flows through the channel to the outlet, where condensate comes out. Since the oxygen content in the steam is small, the possibility of oxygen entering the reactor 1 is reduced.

[0046] The sealing tube 201 controls the sealing and opening / closing of a specific area at the bottom of the reactor 1. The sealing tube 201 is fixed to the front side of the bottom of the reactor 1, serving as a connector and seal. The rotating shaft 202 is connected to the front top of the sealing tube 201, enabling the cover plate 203 to rotate. Through the rotating shaft 202, the cover plate 203 can open and close. When open, it may be used to discharge materials from the reactor 1, clean or repair related components at the bottom; when closed, it ensures the bottom of the reactor 1 is sealed, preventing material leakage and the entry of external impurities. The connecting shaft 204 is fixed around the outer wall of the sealing tube 201, providing support for the screw 205. With the rotating base, screw 205 is rotatable within connecting shaft 204. Nut 206 is threadedly connected to screw 205. Handle 207 is fixed to the top of nut 206. Rotating handle 207 causes nut 206 to rotate. Due to the thread, nut 206 moves up and down along screw 205. When it is necessary to lock cover 203 in the closed state, rotating handle 207 causes nut 206 to move downwards and press against cover 203 to enhance the sealing effect. To open cover 203, rotating handle 207 in the opposite direction causes nut 206 to rise and release the lock on cover 203.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
