[0002] The cement solidification process in a fully sealed mixing barrel with a discarded paddle is a cement solidification technology used to treat radioactive waste liquid. It uses a fully sealed mixing barrel for the solidification process and ensures the closedness and safety of the solidification process by not using an external mixing paddle, thereby effectively solidifying the waste liquid and reducing the risk of leakage of radioactive materials.

[0003] However, when the existing equipment is stirring, the mud is affected by centrifugal force and the edge of the mud rises, causing the mud to block the entire exhaust port, causing the mud to enter the exhaust port and pollute the entire exhaust pipe, thereby causing the entire exhaust pipe to leak. This needs to be improved. Summary of the invention

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0030] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0031] Example 1 is the first example of the present invention, which provides a method for preventing mud from leaking in a cement curing barrel. The method includes using a laser ranging module to monitor the liquid level, and adjusting the height of the limit ring through a motor to prevent the mud from clogging the exhaust pipe, and at the same time detecting whether the exhaust channel is leaking through a pressure relief valve and a pressure sensor; if there is no leakage, the external exhaust is removed, the cement curing is completed and transferred to a temporary storage warehouse; if there is a leakage, the stop valve is closed and the ultrasonic pulse cleaning module and the fan back-blowing module are used for cleaning; after the cleaning is completed, the cement curing process is terminated, and the cement curing barrel is moved to a temporary storage warehouse.

[0032] Among them, the cement solidification barrel is mainly used to mix waste liquid and cement, so as to solidify the waste liquid and reduce the pollution of the waste liquid to the environment. The laser ranging module is mainly used to monitor the liquid level of the internal solution to prevent excessive internal solution from affecting the stirring of the equipment.

[0033] In addition, the motor is used to control the height of the limit ring, so that the limit ring can move up and down inside the curing barrel, thereby better blocking the mud and preventing the mud from leaking, thereby causing the leakage of radioactive materials and affecting the environment.

[0034] Finally, the pressure relief valve is used to release the internal pressure to prevent the internal pressure from being too high, and the pressure sensor is used to detect the internal pressure and prevent the pressure relief valve from failing to work and causing damage to the equipment.

[0035] Preferably, when a leak occurs, the back-blowing system will increase the internal air pressure, causing the air pressure to be too high. When the pressure reaches a critical value, the pressure relief valve will operate, and the internal gas will be released, causing the equipment on the outside to leak. After the leak occurs, the valve needs to be closed, and then the exhaust pipe needs to be removed, and the curing barrel needs to be stored separately. When no leak occurs, only the exhaust pipe needs to be removed, and the curing barrel needs to be stored, thereby completing the treatment of the waste liquid.

[0036] Furthermore, the cement curing barrel is pre-inspected to ensure that the barrel is not damaged, the seals are intact, and all sensors and actuators are in normal working condition. Only after the pre-inspection is passed can the cement filling and curing operation be carried out.

[0037] Furthermore, in addition to controlling the operation of the motor through the laser ranging module to adjust the height of the limit ring, it also includes an automatic feedback adjustment system, which automatically adjusts the operating speed of the motor and the position of the limit ring according to the actual flow and properties of the mud, so as to achieve more precise liquid level control and mud blocking.

[0038] In summary: by mixing the waste liquid and cement inside the curing barrel, the waste liquid is solidified to reduce the risk of leakage of radioactive materials; the height of the liquid level is determined by detection by a laser rangefinder, and then the motor is operated to move up and down on the upper side of the threaded rod, thereby driving the limit ring to move up and down to prevent the mud from submerging the limit ring; when a leak occurs, the back-blowing system will increase the internal air pressure, causing the air pressure to be too high. When the pressure reaches the critical value, the pressure relief valve will operate, and the internal gas will be released, causing the equipment to leak on the outside; after a leak occurs, the valve needs to be closed, and then the exhaust pipe needs to be removed and the curing barrel needs to be stored separately; when no leak occurs, only the exhaust pipe needs to be removed and the curing barrel needs to be stored, thereby completing the treatment of the waste liquid.

[0039] Example 2, reference Figure 1 to Figure 3 , which is the second embodiment of the present invention, is the second embodiment of the present invention, and provides a cement curing barrel mud leakage prevention device, which includes: an leakage prevention system 100, including a curing barrel body 101, an agitator 104 arranged inside the curing barrel body 101, a transparent polymer exhaust pipe 110 arranged on the upper side of the curing barrel body 101, and a pressure relief device 120 arranged on the transparent polymer exhaust pipe 110.

[0040] Among them, the curing barrel body 101 is used to provide a mixing space for the entire equipment, the agitator 104 is used to stir the waste liquid and cement, so that the two are mixed more evenly and thoroughly, the transparent polymer exhaust pipe 110 is used to discharge the air inside the curing barrel body 101, and the pressure relief device 120 is used to relieve pressure when the internal air pressure is too high.

[0041] Preferably, the waste liquid and cement are mixed together through the curing barrel body 101, and then mixed through the agitator 104. At the same time, the gas inside the curing barrel is discharged through the transparent polymer exhaust pipe 110. When blockage occurs, the internal gas is discharged through the pressure relief valve to prevent damage to the equipment caused by excessive pressure.

[0042] Furthermore, the outer wall of the transparent polymer exhaust pipe 110 is provided with a connector 111, a hose 112 arranged on the connector 111, an ultrasonic pulse cleaning module arranged on the transparent polymer exhaust pipe 110, a fan back-blowing module 114 arranged on the transparent polymer exhaust pipe 110, and a pressure sensor 116 arranged on the transparent polymer exhaust pipe 110.

[0043] Among them, the connector 111 is used to connect the transparent polymer exhaust pipe 110 and the outer storage container, the ultrasonic pulse cleaning module is used to clean the interior, thereby assisting the fan back-blowing module to clean the equipment, and the pressure sensor 116 is used to monitor the internal air pressure in real time.

[0044] Preferably, when leakage occurs, the blower back-blowing module and the ultrasonic pulse cleaning module cooperate with each other to clean the entire device to prevent the leaked mud from contaminating the entire device.

[0045] Furthermore, a sealing cover plate 102 , an injection port 103 disposed on the sealing cover plate 102 , and a laser distance measurement module 105 disposed on the sealing cover plate 102 are disposed at the top end of the curing barrel body 101 .

[0046] Among them, the sealing cover plate 102 is used to seal the entire curing barrel body 101, the injection port 103 is used to inject an appropriate amount of waste liquid into the barrel for curing treatment, and the laser ranging module 105 is used to position the waste liquid and the limit ring in the barrel, thereby ensuring that the limit ring is always above the liquid level.

[0047] Furthermore, the anti-leakage system 100 also includes an adjustment assembly 130, a fixed block 131 arranged inside the curing barrel body 101, a threaded rod 132 arranged on the fixed block 131, a linear drive motor 133 arranged on the threaded rod 132, a limit ring 134 arranged on the linear drive motor 133, and an ultrasonic ranging module 135 arranged on the upper fixed block 131.

[0048] Among them, the setting of the fixed block 131 is used to limit the position of the threaded rod 132, the setting of the linear drive motor 133 is used to control its up and down movement on the threaded rod 132, thereby driving the limit ring 134 to move up and down, and the setting of the ultrasonic ranging module 135 is used to cooperate with the linear drive motor 133 to limit the height of the limit ring.

[0049] In summary: cement and waste liquid are mixed together through the setting of the solidification tube body, and then the two are mixed through the agitator 104. During the above operation, the internal gas is discharged through the transparent polymer exhaust pipe 110 to prevent the internal air pressure from being too high and affecting the sealing of the entire equipment. Later, when blockage occurs, the fan back-blowing module and the ultrasonic pulse cleaning module cooperate with each other to clean the entire equipment to prevent the leaked mud from contaminating the entire equipment.

[0050] Example 3, reference Figure 2 to Figure 7 , which is the third embodiment of the present invention, includes: the pressure relief device 120 includes a connecting pipe 121, a shell 122 arranged on the connecting pipe 121, a through hole 123 arranged on the shell 122, a sealing plate 125 arranged inside the through hole 123, an air vent 126 arranged on the sealing plate 125, a pressure relief spring 127 arranged on the sealing plate 125, and a positioning column 124 arranged on the sealing plate 125.

[0051] Among them, the connecting tube 121 is used to connect the outer shell 122 and the transparent polymer exhaust pipe 110, the through hole 123 is used to facilitate the movement of the internal sealing plate 125, so that the air vent 126 can discharge the internal gas, the pressure relief spring 127 is used to push out the sealing ring, and the positioning column 124 is used to limit the sealing ring to prevent it from flipping inside.

[0052] Furthermore, the air holes 126 are in the shape of circular holes, which reduce the turbulence of the airflow and usually produce a relatively smooth airflow, so the sound is relatively continuous and uniform, and usually lower.

[0053] Furthermore, the air holes 126 are in the shape of square or rectangular holes, and airflow passing through the holes may generate turbulence at the edges of the holes, may have more harmonic components, and the sound may be sharper than that of circular holes.

[0054] Furthermore, the air holes 126 are in the shape of triangles or diamonds. Due to the sharp edges, turbulence is easily generated, and the sound is sharper and more complex, with more high-frequency components, and the sound may be more harsh.

[0055] Furthermore, the air holes 126 are slit-shaped holes, and when air flows through the slits, high-frequency vibrations are generated, and the sound is sharp, usually a high-frequency sound, similar to the sound of a whistle or a whistle.

[0056] Preferably, when the internal air pressure is too high, the gas will squeeze the sealing plate 125, causing the sealing plate 125 to move upward. When the air hole 126 passes through the through hole 123, the internal gas is discharged from the device through the air hole 126. At the same time, when exhausting, due to the specific shape of the air hole 126, an alarm will be sounded, thereby prompting on-site personnel, thereby facilitating on-site personnel to perform maintenance.

[0057] In summary: by integrating laser ranging, motor adjustment, pressure relief detection, cleaning module and various pressure relief hole shape designs, the safety and efficiency of the cement curing process are effectively improved, and the liquid level can be monitored and adjusted in real time to prevent mud blockage, ensure the smooth flow of the exhaust channel, and promptly detect and deal with leaks to avoid environmental pollution and material loss; the coordinated use of ultrasonic pulse cleaning and fan back-blowing module 114 ensures the cleanliness of the exhaust system and extends the service life of the equipment. The air vent 126 design can relieve internal pressure and provide operational feedback through sound characteristics, making maintenance easier and improving the overall automation level and reliability of cement curing operations.
