Abstract
Description
Technical Field
[0001] This utility model relates to the field of distillation column technology, specifically to an anti-clogging flushing structure for a distillation column level gauge. Background Technology
[0002] In the field of chemical production, distillation columns are a crucial and commonly used separation device used to separate and purify the components in a mixture. Distillation column level gauges are important monitoring devices that ensure the stable and efficient operation of distillation columns. They can measure the liquid level in the distillation column in real time and accurately, providing operators with key data to precisely control process parameters such as feed rate, discharge rate, and reflux ratio, ensuring that the distillation process is carried out under optimal conditions, thereby producing products that meet quality requirements.
[0003] However, the materials processed by distillation columns are often complex in composition, containing various solid particles, polymers, colloidal substances, and corrosive components. During the distillation process, these impurities easily deposit and adhere to relevant structural parts of the distillation column level gauge as the material circulates within the column. Over time, these impurities accumulate and gradually clog critical parts of the level gauge, such as the measuring channels, sensor pores, and connecting pipes, severely affecting the normal measurement function of the level gauge.
[0004] Most existing anti-clogging structures for distillation column level gauges are relatively simple in design, typically relying on a single filter device for preliminary filtration of the medium entering the level gauge. However, this filtration method has limited effectiveness in intercepting some small particles, colloidal substances, or sticky impurities, and cannot effectively prevent these impurities from entering the level gauge. Moreover, over time, the filter device is easily clogged by impurities, leading to poor medium flow. This not only affects measurement accuracy but also requires frequent shutdowns for cleaning or replacement of the filter device, increasing production and maintenance costs and downtime, and reducing production efficiency.
[0005] When a level gauge becomes clogged, some existing structures are equipped with flushing devices, but the flushing methods are often not flexible and effective enough. Some flushing devices can only provide flushing in a fixed direction and pressure, making it difficult to flush the clogged area thoroughly and accurately. In particular, for some stubborn blockages, such as impurities tightly adhering to narrow channels or sensor surfaces, existing flushing methods are difficult to completely remove them. As a result, the level gauge cannot restore its normal measurement function after flushing, and further complicated measures such as manual cleaning are required, which increases the difficulty of operation and labor intensity.
[0006] To address the above shortcomings, an anti-clogging flushing structure for a distillation column level gauge is proposed. Utility Model Content
[0007] This invention provides an anti-clogging flushing structure for a distillation column level gauge, aiming to improve the problems of poor anti-clogging effect and limited flushing and unblocking ability.
[0008] This utility model is implemented as follows: a clogging-proof flushing structure for a distillation column level gauge includes a main cylinder, a flushing cylinder, and a propulsion component. The flushing cylinder is provided at the top of the main cylinder, and the propulsion component is provided at the bottom of the inner cavity of the main cylinder. A flow tube is provided at the center of the inner cavity of the main cylinder. A fixed slot is provided at the center of the flow tube. A drive shaft is provided on the inner side of the fixed slot. Three isolation plates are provided on the top of the drive shaft. An inlet is provided on the top side of the flushing cylinder. A flushing inner cavity is provided in the inner cavity of the flushing cylinder. An outlet connected to the inlet is provided on the inner wall side of the flushing inner cavity. The propulsion component includes a guide cylinder, which is disposed on the outer surface of the drive shaft. A base plate is disposed at the bottom of the drive shaft, and a filter plate that fits into the inner cavity of the main cylinder is disposed at the bottom of the base plate.
[0009] Preferably, a positioning slot is provided at the top of the main cylinder, and a positioning block is provided at the bottom of the rinsing cylinder, with the positioning block engaging with the inside of the positioning slot.
[0010] Preferably, a drive motor is fixedly installed on the inner side of the housing, and three isolation plates are arranged in a circumferential array at the bottom of the housing. A common cover plate is provided at the opposite position of the three isolation plates, and the top surface of the cover plate is provided with a reinforcement hole for fixing to the inner plate.
[0011] Preferably, an inner plate with the same plane as the isolation plate is provided on the inner side of the isolation plate. The outer surfaces of the isolation plate and the inner plate can form a circular structure. A connecting rod located inside the cover plate is provided at the inner end of the inner plate. The output end of the drive motor is fixed to the connecting rod.
[0012] Preferably, the inner wall of the main cylinder is provided with a sliding groove, and the outer side of the isolation plate is provided with a sliding block corresponding to the sliding groove. The isolation plate is slidably installed on the inner side of the sliding groove.
[0013] Preferably, the inner wall of the flushing cylinder is provided with a guide groove that communicates with the inlet, the other end of the guide groove is connected to the outlet, and a flushing nozzle located in the inner cavity of the flushing chamber is provided on the outside of the outlet.
[0014] Preferably, the outer surface of the guide cylinder is provided with an upper through hole that fits with the drive shaft, and the inner cavity of the substrate is provided with a lower through hole that connects to the upper through hole.
[0015] Preferably, the top of the filter plate is provided with a guide rod that engages with the base plate, and a sliding ball that fits against the inner wall of the main cylinder is movably installed on the outside of the filter plate.
[0016] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model has a base plate inside the main cylinder and a filter plate at its bottom, which can perform comprehensive and meticulous filtration of the incoming medium, effectively intercepting most solid particles and impurities. The sliding ball installed on the outside of the filter plate allows it to slide smoothly inside the main cylinder, which not only reduces friction with the inner wall and ensures stable operation of the filter plate, but also avoids the formation of new blockage points due to localized medium accumulation caused by poor filter plate movement. At the same time, the coordinated design of the guide cylinder, upper through hole and lower through hole in the propulsion component can guide the easily clogged medium in contact with the drive shaft to flow downward, preventing it from accumulating around the drive shaft and affecting the sliding effect of the drive shaft, thereby ensuring the stability of the entire structure and reducing production interruptions and cost increases caused by frequent cleaning of blockages.
[0017] 2. This utility model is equipped with a drive motor that rotates the built-in plate, forming a circular structure with the isolation plate and pressing it down to fix it. Combined with the downward pressure of the propulsion component, this changes the air pressure inside the main cylinder, generating a powerful air pressure flushing effect. This applies pressure to the blocked area from the inside, effectively loosening and dispersing stubborn blockages. Furthermore, the flushing cylinder is equipped with flushing nozzles that can be directed into the blocked area through the slots left after the built-in plate closes, ensuring that the flushing medium directly acts on the blockage point, improving the accuracy and effectiveness of the flushing, quickly and thoroughly removing impurities, and allowing the distillation column level gauge to quickly return to normal measurement operation. This reduces the hassle and difficulty of manual cleaning, improving production efficiency and equipment reliability. Attached Figure Description

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0023] Example 1 Please see Figure 1-5 A clog-proof flushing structure for a distillation column level gauge includes a main cylinder 1, a flushing cylinder 2, and a propulsion component. The main cylinder 1 serves as the primary space for media flow. The flushing cylinder 2 is located at the top of the main cylinder 1 and provides flushing functionality. The propulsion component is located at the bottom of the inner cavity of the main cylinder 1. A flow tube 5 is located at the center of the inner cavity of the main cylinder 1, which facilitates stable media flow and measurement. A fixing slot 51 is formed at the center of the flow tube 5, and a drive shaft 3 is located inside the fixing slot 51. The fixing slot 51 provides a precise installation position for the drive shaft 3, ensuring that the drive shaft 3 can stably transmit power. As a key component for power transmission, the drive shaft 3 connects different functional structures above and below, transmitting power from power sources such as the drive motor 41 to actuators such as the isolation plate 6, achieving coordinated operation of the entire structure. It is the core transmission element that ensures the normal operation of the clog-proof flushing function.
[0024] The main cylinder 1 has a positioning slot 11 at the top and a positioning block 21 at the bottom of the rinsing cylinder 2. The positioning block 21 is engaged with the inside of the positioning slot 11, thus achieving precise positioning and stable connection between the main cylinder 1 and the rinsing cylinder 2.
[0025] Three isolation plates 6 are provided on the top of the drive shaft 3. The drive motor 41 is fixedly installed on the inner side of the housing 4. The housing 4 is used to protect the drive motor 41. The three isolation plates 6 are arranged in a circumferential array at the bottom of the housing 4. A common cover plate 61 is provided at the opposite position of the three isolation plates 6. The top surface of the cover plate 61 is provided with a reinforcing hole 63 that is fixed to the inner plate 62.
[0026] like Figure 3 , 4 As shown, an inner plate 62 with the same plane as the isolation plate 6 is provided on the inner side of the isolation plate 6. The outer surfaces of the isolation plate 6 and the inner plate 62 can form a circular structure. A connecting rod located inside the cover plate 61 is provided at the inner end of the inner plate 62. The output end of the drive motor 41 is fixed to the connecting rod. The drive motor 41 is the power source of the entire structure. It is connected to the inner plate 62 through the connecting rod and can precisely control the rotation of the inner plate 62.
[0027] It should be noted that when air pressure flushing is required, the built-in plate 62 rotates to form a circular structure with the isolation plate 6 and presses down to fix the reinforcing hole 63. Then, with the help of the propulsion component, the air pressure inside the main cylinder 1 can be changed to produce an air pressure flushing effect, effectively clearing the blocked parts.
[0028] The inner wall of the main cylinder 1 is provided with a sliding groove 12 to provide a track for the sliding installation of the isolation plate 6. The outer side of the isolation plate 6 is provided with a sliding block corresponding to the sliding groove 12. The isolation plate 6 is slidably installed on the inner side of the sliding groove 12, providing a precise track and stable support for the sliding of the isolation plate 6 in the main cylinder 1.
[0029] like Figure 5 As shown, an inlet 7 is provided on the top side of the flushing cylinder 2, and a flushing inner cavity 22 is provided in the inner cavity of the flushing cylinder 2. An outlet 8 connected to the inlet 7 is provided on the inner wall side of the flushing inner cavity 22. A guide groove 81 connected to the inlet 7 is provided on the inner wall of the flushing cylinder 2. The other end of the guide groove 81 is connected to the outlet 8. A flushing nozzle 82 located in the inner cavity of the flushing inner cavity 22 is provided on the outside of the outlet 8 so as to accurately spray the flushing medium for flushing operation.
[0030] Among them, the flushing nozzle 82 can accurately spray the flushing medium at a suitable angle and pressure, and align it with the slot that is left after the inner plate 62 is closed, so as to perform targeted flushing on the blocked parts in the main cylinder 1, improve the flushing effect, effectively remove impurities, prevent blockage, and ensure the normal measurement work of the distillation column level gauge.
[0031] Example 2 Please see Figure 1-2The propulsion component includes a guide cylinder 31, which is disposed on the outer surface of the drive shaft 3. A base plate 32 is disposed at the bottom of the drive shaft 3. An upper through hole is opened on the outer surface of the guide cylinder 31 to fit against the drive shaft 3. A lower through hole is opened in the inner cavity of the base plate 32 to connect with the upper through hole. The upper through hole and the lower through hole are connected and can be used to guide the easily clogged medium that is in contact with the drive shaft 3, so that it flows downward and prevents it from affecting the sliding effect of the drive shaft 3.
[0032] A filter plate 9 is provided at the bottom of the substrate 32, which is in contact with the inner cavity of the main cylinder 1. A guide rod 91 is provided at the top of the filter plate 9, which is engaged with the substrate 32. The installation is convenient and the connection is stable. A ball bearing 92 is movably installed on the outside of the filter plate 9, which is in contact with the inner wall of the main cylinder 1, so that the filter plate 9 can slide smoothly in the main cylinder 1, reducing friction with the inner wall of the main cylinder 1. At the same time, the filter plate 9 can filter the medium entering the main cylinder 1, preventing impurities from entering the subsequent structure and causing blockage.
[0033] It should be noted that by pushing the drive shaft 3 to slide up and down, the filter plate 9 and the ball 92 slide, while the circular structure formed by the isolation plate 6 and the built-in plate 62 is compressed downward, which achieves the effect of air pressure flushing and unblocking.
[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
