Description

Technical Field

[0001] This application relates to the field of evaporation equipment technology, and in particular to the installation structure of the liquid level gauge in the evaporation chamber. Background Technology

[0002] Evaporation chambers are core equipment in industrial evaporation processes, primarily used for the evaporation and concentration of materials, and are widely used in industries such as chemical, food, and pharmaceutical. Level gauges, as crucial supporting devices within the evaporation chamber, are used to monitor the liquid level of the material inside in real time. The accuracy of this monitoring directly affects the stability, safety, and product quality of the production process.

[0003] In the existing technology, the installation of the evaporation chamber level gauge usually adopts a vertical or horizontal connecting pipe, with one end of the connecting pipe connected to the side wall of the evaporation chamber and the other end connected to the level gauge.

[0004] Regarding the aforementioned technologies, the inventors believe that the materials in the evaporation chamber often contain easily precipitated components such as salts. The precipitated salts tend to accumulate in the horizontal connecting pipe, causing blockage of the level gauge interface, resulting in distorted level monitoring data and affecting production control. Utility Model Content

[0005] The purpose of this application is to provide an installation structure for an evaporation chamber level gauge to improve the problem that precipitated salts tend to accumulate in horizontal connecting pipes, causing blockage of the level gauge interface, resulting in distorted level monitoring data and affecting production control.

[0006] The evaporation chamber level gauge installation structure provided in this application adopts the following technical solution: An evaporation chamber level gauge installation structure includes a cylinder. An installation pipe, which is inclinedly arranged on the bottom side wall of the cylinder and communicates with the inside of the cylinder, is provided. The end of the installation pipe away from the cylinder is higher than the other end of the installation pipe. A connecting flange is provided at the end of the installation pipe away from the cylinder. A level gauge body is provided on one side of the connecting flange. The probe of the level gauge body enters the inside of the installation pipe and comes into contact with the liquid inside the cylinder of the evaporation chamber.

[0007] By adopting the above technical solution, an installation pipe is inclinedly installed on the bottom side wall of the cylinder, with the end of the installation pipe away from the cylinder being higher than the end near the cylinder. This ensures that the probe of the level gauge body can smoothly enter the installation pipe and contact the liquid in the evaporation chamber, thus realizing the liquid level monitoring function. At the same time, the gravity guiding effect of the inclined structure can be used to make the precipitated salt particles in the evaporation chamber flow back to the cylinder along the inner wall of the installation pipe, reducing the accumulation of sediment in the installation pipe, reducing the risk of blockage, and ensuring the continuity and accuracy of liquid level monitoring.

[0008] Optionally, the liquid level gauge body is provided with a mounting flange that is bolted to the connecting flange, the mounting flange is provided with a sealing gasket facing the connecting flange, and the circumferential sidewall of the mounting flange is provided with an annular plate extending towards the connecting flange, the annular plate being in contact with the sidewall of the connecting flange.

[0009] By adopting the above technical solution, the bolted connection between the mounting flange and the connecting flange ensures the firm fixation of the level gauge body and the mounting pipe. The setting of the sealing gasket can effectively prevent the leakage of materials in the evaporation chamber and ensure production safety. The ring plate fits against the side wall of the connecting flange, which enhances the connection stability between the mounting flange and the connecting flange, prevents the connection from loosening, and further improves the sealing effect.

[0010] Optionally, the connecting flange has a plurality of positioning grooves on its circumferential sidewall, and the annular plate has positioning blocks at intervals corresponding to the positioning grooves on its sidewall.

[0011] By adopting the above technical solution, the positioning groove on the connecting flange cooperates with the positioning block on the ring plate, which can achieve rapid and accurate positioning during the installation of the liquid level gauge body, ensuring that the bolt holes of the mounting flange and the connecting flange are accurately aligned, reducing the alignment adjustment time during assembly, and improving installation efficiency.

[0012] Optionally, the end of the positioning block is provided with a guide surface corresponding to the positioning groove.

[0013] By adopting the above technical solution, the guide surface at the end of the positioning block can guide the positioning block into the positioning groove during the assembly process, reduce the probability of collision between the positioning block and the edge of the positioning groove, reduce component wear, make the positioning block easier to slide into the positioning groove, and further improve assembly convenience and efficiency.

[0014] Optionally, the connecting flange has a sealing groove corresponding to the sealing gasket, the inner wall of the sealing groove has a corrugated groove, and the sealing gasket has a protrusion corresponding to the corrugated groove.

[0015] By adopting the above technical solution, the sealing groove can form a circumferential positioning for the sealing gasket, preventing the sealing gasket from shifting during installation or use. The corrugated groove on the inner wall of the sealing groove cooperates with the protrusion of the sealing gasket, increasing the sealing contact area and the roughness of the sealing surface, making the sealing gasket fit more tightly with the sealing groove, significantly improving the sealing performance, effectively blocking the leakage of materials in the evaporation chamber, and adapting to the pressure environment of the evaporation chamber.

[0016] Optionally, a support frame is provided on the side wall of the cylinder facing the installation pipe, and a limiting groove is provided at the end of the support frame to fit against the side wall of the installation pipe. A fixing clamp for fixing the installation pipe is rotatably provided at the end of the support frame.

[0017] By adopting the above technical solution, the limiting groove of the support frame fits into the side wall of the installation pipe, and the rotating fixing clamp fixes the installation pipe, ensuring that the tilt posture of the installation pipe is stable in the long term, and avoiding liquid level monitoring errors or increased blockage risks caused by the displacement of the installation pipe.

[0018] Optionally, a flushing pipe is provided inside the cylinder facing the inlet of the mounting pipe. The flushing pipe passes through the side wall of the cylinder, and a nozzle corresponding to the inside of the mounting pipe is provided at the end of the flushing pipe.

[0019] By adopting the above technical solution, the flushing pipe and end nozzles installed inside the cylinder facing the installation pipe opening can be connected to an external water source to periodically flush the inside of the installation pipe after the evaporation chamber is shut down, so as to remove the residual sediment in the pipe in time. In conjunction with the inclined installation pipe, the liquid can flow back, further reducing the probability of blockage, reducing the number of manual cleanings, and ensuring the long-term stable operation of the level gauge.

[0020] Optionally, an observation window is provided on the side wall of the cylinder above the mounting tube.

[0021] By adopting the above technical solution, the observation window above the mounting pipe on the cylinder allows operators to directly observe the liquid level and material status in the evaporation chamber, promptly detect material sedimentation and abnormal changes in liquid level, and improve the convenience and safety of production operations.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. An installation pipe is installed at an angle on the bottom side wall of the cylinder, with the end of the installation pipe away from the cylinder being higher than the end near the cylinder. This ensures that the probe of the level gauge body can smoothly enter the installation pipe and contact the liquid in the evaporation chamber, thus realizing the liquid level monitoring function. At the same time, the gravity guiding effect of the inclined structure can be used to make the precipitated salt particles in the evaporation chamber flow back to the cylinder along the inner wall of the installation pipe, reducing the accumulation of sediment in the installation pipe, reducing the risk of blockage, and ensuring the continuity and accuracy of liquid level monitoring. 2. The positioning groove on the connecting flange cooperates with the positioning block on the ring plate to achieve rapid and accurate positioning during the installation of the level gauge body, ensuring that the bolt holes of the mounting flange and the connecting flange are accurately aligned, reducing the alignment adjustment time during assembly and improving installation efficiency; 3. The inclination angle of the installation pipe is 20°-30°, which can ensure that the liquid in the evaporation chamber flows smoothly into the installation pipe to meet the monitoring requirements of the level gauge probe; it can also guide the precipitated salt particles back to the cylinder along the installation pipe to prevent the accumulation of sediment due to too small an angle or insufficient liquid retention due to too large an angle.

Detailed Implementation

[0025] The following is in conjunction with the appendix Figure 1 -Appendix Figure 3 This application will be described in further detail below.

[0026] The installation structure of the evaporation chamber level gauge is as follows: Figure 1 and Figure 2 The system includes a cylindrical body 1 with an evaporation chamber. An installation pipe 2 is inclinedly installed on the bottom side wall of the cylindrical body 1. The installation pipe 2 is sealed to the hole on the side wall of the cylindrical body 1 with bolts and sealing rings, so that one end of the installation pipe 2 is connected to the inside of the cylindrical body 1, and the other end is higher than the end close to the cylindrical body 1, with an inclination angle of 20°-30°. A connecting flange 21 is welded to the end of the installation pipe 2 away from the cylindrical body 1. The connecting flange 21 is used to connect the liquid level gauge body 3. The liquid level gauge body 3 is a hydrostatic liquid level gauge that is electrically connected to the power supply and control system. The probe of the liquid level gauge body 3 smoothly enters the inside of the installation pipe 2 and contacts the liquid in the evaporation chamber to realize the liquid level monitoring function. The salt particles after precipitation in the evaporation chamber flow back to the cylindrical body 1 along the inner wall of the installation pipe 2, reducing the accumulation of sediment in the installation pipe 2 and reducing the risk of blockage.

[0027] Reference Figure 2 and Figure 3 An installation flange 31 is installed at one end of the level gauge body 3 near the installation pipe 2. The installation flange 31 is detachably connected to the connecting flange 21 by bolts. A sealing gasket 4 is adhered to the side of the installation flange 31 facing the connecting flange 21 to prevent material leakage in the evaporation chamber. The circumferential sidewall of the installation flange 31 extends toward the connecting flange 21 to form an annular plate 32. The annular plate 32 fits against the outer sidewall of the connecting flange 21. Several positioning grooves 22 are evenly spaced on the circumferential sidewall of the connecting flange 21. Positioning blocks 33 that are adapted to the positioning grooves 22 are welded to the sidewall of the annular plate 32 at corresponding intervals. The end of the positioning block 33 is provided with a guide surface 34 facing the positioning groove 22, so that the positioning block 33 can slide into the positioning groove 22 more easily.

[0028] Reference Figure 2 and Figure 3A sealing groove 23 adapted to the sealing gasket 4 is provided on the side of the connecting flange 21 facing the mounting flange 31. The sealing gasket 4 is embedded in the sealing groove 23. An annular corrugated groove 24 is provided on the inner side wall of the sealing groove 23. A protrusion 41 adapted to the corrugated groove 24 is provided on the outer side wall of the sealing gasket 4. The corrugated groove 24 on the inner side wall of the sealing groove and the protrusion 41 on the sealing gasket 4 cooperate to increase the sealing contact area and the roughness of the sealing surface, so that the sealing gasket 4 and the sealing groove 23 fit more tightly and significantly improve the sealing performance.

[0029] Reference Figure 2 Inside the cylinder 1, facing the opening of the mounting pipe 2, there is a flushing pipe 6 made of stainless steel. One end of the flushing pipe 6 passes through the side wall of the cylinder 1 and extends to the outside for connecting to a water pump (not shown in the figure) and a valve to interrupt the water flow. The other end is located inside the cylinder 1 and is equipped with a nozzle 61. The spray direction of the nozzle 61 corresponds to the inside of the mounting pipe 2. After the evaporation chamber is stopped, the inside of the mounting pipe 2 is flushed to remove the residual sediment in the pipe in time.

[0030] Reference Figure 1 and Figure 2 A support frame 5 is bolted to the side wall of the cylinder 1 at the position corresponding to the installation pipe 2. An arc-shaped limiting groove 51 is opened at the end of the support frame 5 away from the cylinder 1, which fits against the outer side wall of the installation pipe 2. A fixing clamp 52 is rotatably hinged at the opening of the limiting groove 51. After the fixing clamp 52 is locked with bolts, the installation pipe 2 can be fixed in the limiting groove 51 to ensure the long-term stability of the tilt posture of the installation pipe 2 and avoid liquid level monitoring errors or increased blockage risk caused by the displacement of the installation pipe 2. A transparent observation window 11 is embedded in the side wall of the cylinder 1 above the installation pipe 2. The observation window 11 is made of tempered glass or corrosion-resistant acrylic material, which makes it easy for operators to directly observe the liquid level and material status in the evaporation chamber.

[0031] The implementation principle of this application embodiment is as follows: An installation pipe 2 is installed at an angle on the side wall of the evaporation chamber cylinder 1. The installation flange 31 of the level gauge body 3 and the connecting flange 21 at the end of the installation pipe 2 are quickly and accurately positioned by the positioning block 33 and the positioning groove 22. After bolt connection, the ring plate 32 fits to enhance stability. The sealing gasket 4 in the sealing groove 23 cooperates with the corrugated groove 24 and the protrusion 41 to achieve efficient sealing and prevent material leakage. Gravity is used to guide the precipitated salt particles in the evaporation chamber back to the cylinder 1 along the installation pipe 2. At the same time, it ensures that the liquid enters the installation pipe 2 for the detection head of the level gauge body 3 to monitor, reduces the accumulation of sediment in the installation pipe 2, reduces the risk of blockage, and ensures the continuity and accuracy of level monitoring.
