[0002] In the methanol to olefins (MTO) production process, as the core raw material, the liquid level in the storage container of methanol is very important to measure accurately. Because of the complex MTO production conditions, the methanol in the storage container is prone to violent liquid level fluctuation due to factors such as material transportation and equipment vibration, and the traditional liquid level measuring device cannot obtain stable and accurate measurement data. At the same time, methanol is strongly corrosive, and measuring components made of ordinary materials are easily corroded and damaged, affecting the measurement accuracy and equipment life. In addition, if the liquid level data cannot be fed back in time and accurately, it may cause the production process to be interrupted, material to be wasted, and even safety accidents. Therefore, a liquid level measuring device that can adapt to complex conditions, has corrosion resistance and stable measurement is urgently needed to ensure the continuity and safety of the MTO production process.

[0003] Therefore, we propose a kind of MTO grade methanol liquid level stable measuring device. CONTENT OF THE UTILITY MODEL

[0028] Example: A stable MTO-grade methanol level measuring device, such as... Figures 1-4 As shown, the system includes a buffer chamber 1, with several partitions 2 fixedly installed on its inner wall. A connecting rod 3 is movably installed at the top of the inner wall of the buffer chamber 1, and a float 4 is fixedly installed at the bottom of the connecting rod 3. A drive shaft 5 is movably installed on one side of the inner wall of the buffer chamber 1, and a drive gear 6 is fitted on the surface of the drive shaft 5. One side of the drive gear 6 meshes with the connecting rod 3. A pointer dial 7 is opened on one side of the surface of the buffer chamber 1. A connecting pipe 8 is fixedly installed at the bottom of the buffer chamber 1, and the bottom end of the connecting pipe 8 passes through the top of the methanol storage container and is fixedly installed. A sealing sleeve 9 is fitted on the bottom end of the connecting pipe 8. A ceramic fiber layer 10 is fixedly installed on the outer side of the cavity of the sealing sleeve 9, and a rubber sealing layer 11 is fixedly installed on the inner side of the cavity of the sealing layer. The rack 16 on the surface of the connecting rod 3 precisely meshes with the drive gear 6, accurately converting the vertical displacement of the float 4 into the rotational motion of the gear, thereby driving the drive shaft 5 and the pointer dial 7 to achieve a visual display of the liquid level. The entire transmission process has a simple and stable mechanical structure, reducing the risk of failure caused by complex transmission components. In terms of sealing, the sealing sleeve 9 at the connecting pipe 8 adopts a double-layer structure. The outer ceramic fiber layer 10 has good heat insulation and high temperature resistance to prevent methanol vapor leakage caused by temperature changes. The inner rubber sealing layer 11 utilizes its high elasticity and sealing properties to effectively prevent methanol liquid from seeping out, which not only ensures the safety of the measurement environment but also extends the service life of the device.

[0029] like Figures 1-4 As shown, the top end of the connecting rod 3 passes through the buffer cavity 1, the connecting rod 3 is located at the center of the buffer cavity 1, and a counterweight 12 is fixedly installed at the top end of the connecting rod.

[0030] The baffles 2 are arranged in multiple layers, with each layer inclined and adjacent baffles inclined in opposite directions. A guide rod 13 is fixedly installed at the top of the inner wall of the buffer chamber 1. The guide rod 13 has the same overall length as the connecting rod 3. A guide block 14 is fixedly installed on one side of the guide rod 13. The inner wall of the buffer chamber 1 in the device is provided with multiple layers of staggered baffles 2 with opposite inclination directions, forming a tortuous flow channel structure. When methanol flows into the buffer chamber 1 from the storage container, the baffles 2 can effectively weaken the impact force and flow rate of the liquid, slow down the liquid flow, and greatly suppress the fluctuation of the liquid surface.

[0031] likeFigures 1-3 As shown, a slot 15 is provided on one side of the surface of the connecting rod 3. The guide block 14 is a semi-circular ring when viewed from above. The inner side of the guide block 14 engages with the slot 15. The outer side of the guide block 14 is fitted with the surface of the connecting rod 3. A rack 16 is provided on the surface of the connecting rod 3. The rack 16 meshes with the transmission gear 6 and drives the transmission gear 6 to rotate. The transmission shaft 5 engages with the pointer surface and drives the pointer on the pointer surface to rotate. The float 4 is a circular hollow sphere. The material of the float 4 should have certain corrosion resistance properties.

[0032] The buffer chamber 1 is located on the top outer side of the methanol storage container. The buffer chamber 1 is cylindrical, and the guide rod 13 at the top of the buffer chamber 1 engages with the slot 15 of the connecting rod 3 to ensure that the float 4 can only move in the vertical direction, avoiding measurement errors caused by lateral swaying. This design allows the liquid level in the buffer chamber 1 to remain relatively stable even when the liquid level in the storage container fluctuates violently, providing a stable measurement environment for the float 4 and significantly improving the accuracy and stability of the measurement.

[0033] Working Principle: When the liquid level in the methanol storage container changes, the liquid flows into or out of the buffer chamber 1 through the connecting pipe 8. Due to the buffering effect of the baffle 2, the fluctuation of the liquid surface in the buffer chamber 1 is greatly reduced. The float 4 rises and falls vertically in sync with the liquid level in the buffer chamber 1, driving the connecting rod 3, which is fixedly connected to it, to move up and down. The rack 16 on the surface of the connecting rod 3 meshes with the transmission gear 6, converting the vertical displacement of the connecting rod 3 into the rotational motion of the transmission gear 6, which in turn drives the transmission shaft 5 to rotate. Because the transmission shaft 5 is fixedly connected to the pointer dial 7, the rotation angle of the transmission shaft 5 is displayed intuitively on the dial by the pointer, thereby realizing real-time measurement and accurate display of the methanol liquid level. Throughout the process, the guiding effect of the guide rod 13 and the slot 15 ensures the stable movement of the connecting rod 3, the counterweight 12 balances the buoyancy of the float 4, and the sealing sleeve 9 prevents methanol leakage, all of which together ensure the stable and reliable operation of the device.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
