Description

Technical Field

[0001] This application relates to the field of equipment cleaning, and in particular to an automatic cleaning device for an online monitoring probe of slurry in a boric acid acidification process. Background Technology

[0002] In the boric acid acidification process for lithium extraction from salt lakes, the composition of the slurry, such as the concentration of lithium, boron, and magnesium ions, needs to be monitored in real time to ensure reaction efficiency. However, traditional monitoring probes are easily adhered to by viscous substances or crystals in the slurry, leading to increased detection errors and requiring frequent manual cleaning. However, manual cleaning has the following drawbacks: untimely cleaning: downtime for cleaning affects production continuity; high operational risk: the strong acid environment threatens personnel safety; decreased accuracy: scaling causes monitoring data to be delayed or distorted. Utility Model Content

[0003] To efficiently and intelligently clean the probe, ensure the safety of staff and the accuracy of monitoring data, this application provides an automatic cleaning device for the online monitoring probe of slurry in the boric acid acidification process.

[0004] The automatic cleaning device for online monitoring probes of slurry in the boric acid acidification process provided in this application adopts the following technical solution:

[0005] An automatic cleaning device for an online monitoring probe of slurry in a boric acid acidification process includes a probe fixedly mounted on one side of the slurry. It also includes a cleaning chamber mounted on one side of the probe, with several high-pressure spray heads fixedly mounted around its periphery. Ultrasonic oscillating rods are fixedly mounted on both sides inside the cleaning chamber. An ultrasonic generator is mounted above the cleaning chamber and electrically connected to the ultrasonic oscillating rods. A waste liquid discharge pipe is located at the bottom of the cleaning chamber. The cleaning chamber has an opening on the side facing the probe, and a cleaning cover plate is mounted on the other side of the probe. A clamping plate is vertically mounted on the side of the cleaning cover plate facing the opening, with a U-shaped groove at its lower end. The probe is placed in the U-shaped groove. A driving mechanism is located on the side of the cleaning cover plate away from the clamping plate to move the probe further into the cleaning chamber. A limiting groove is formed on one side of the cleaning chamber, communicating with the opening. The clamping plate and the limiting groove are located in the same horizontal direction, and the clamping plate can be inserted parallel to the limiting groove and fit against the groove wall.

[0006] By adopting the above technical solution, a cleaning chamber and a cleaning cover are respectively set on both sides of the probe. The probe is held by a clamping plate. Under the action of the driving mechanism, the cleaning cover can move closer to the cleaning chamber, thereby pushing the clamping plate to move the probe into the cleaning chamber. During the movement, the clamping plate is inserted into the limiting groove. When the clamping plate is at its deepest point in the limiting groove, the cleaning cover is in contact with the cleaning chamber, thus placing the probe in a relatively sealed space. By turning on the ultrasonic generator and the high-pressure spray head, the crystals and viscous deposits on the probe can be physically cleaned separately. The waste liquid after cleaning is discharged from the waste liquid discharge pipe, achieving efficient and intelligent cleaning, ensuring the safety of staff and the accuracy of monitoring data.

[0007] Optionally, the sidewall of the cleaning chamber has a double-layer structure, with a high-pressure spray pipe installed in the middle layer of the sidewall. The high-pressure spray pipe is equipped with several high-pressure spray heads, and several perforations are opened in the inner layer of the sidewall of the cleaning chamber. Several high-pressure spray heads pass through the perforations and face the center of the cleaning chamber.

[0008] By adopting the above technical solution, the side wall of the cleaning chamber is divided into inner and outer layers, and a high-pressure spray pipe is set in the middle layer. Multiple high-pressure spray heads can be set along the direction of the high-pressure spray pipe. Multiple high-pressure spray heads can come from different directions and different angles, thereby realizing all-round and multi-angle cleaning probes, and further realizing quick, convenient and efficient cleaning.

[0009] Optionally, the bottom inner layer of the cleaning chamber is provided with a plurality of waste liquid inlet holes, and the bottom outer layer of the cleaning chamber is provided with waste liquid outlet holes, which are connected to waste liquid outlet pipes.

[0010] By adopting the above technical solution, several waste liquid inlet holes are opened in the inner layer at the bottom of the cleaning chamber. The waste liquid falls into the outer layer from multiple waste liquid inlet holes, and then falls into the waste liquid discharge pipe from the outer layer, thereby realizing the collection and treatment of waste liquid. It will not remain in the cleaning chamber and cause secondary contamination of the probe.

[0011] Optionally, the waste liquid discharge pipe is connected to an electrodialysis device.

[0012] By adopting the above technical solution and setting up an electrodialysis device, boric acid and lithium ions in the cleaning waste liquid are separated and recovered, which not only reduces the lithium ion loss rate and improves resource utilization, but also reduces environmental pollution.

[0013] Optionally, the drive mechanism includes a fixed frame and a cylinder. The fixed frame is fixedly installed on the ground or on a device next to the slurry. The fixed part of the cylinder is fixedly installed on the fixed frame, and the moving part of the cylinder is fixedly connected to the cleaning cover plate.

[0014] By adopting the above technical solution, the fixed part of the cylinder is placed horizontally on the fixed frame, and the moving part of the cylinder is connected to the cleaning cover plate. Thus, while fixing and suspending the cleaning cover plate, the cleaning cover plate is pushed to move towards the cleaning cavity and cover the cleaning cavity, or the cleaning cover plate is pulled to move away from the cleaning cavity.

[0015] Optionally, a vacuum pump is connected to the bottom of the cleaning chamber, and a hot air delivery pipe is connected to the top of the cleaning chamber.

[0016] By adopting the above technical solution, after cleaning, the vacuum pump is turned on to extract the air from the cleaning chamber, and then hot air is delivered into the cleaning chamber through the hot air delivery pipe. The vacuum is drawn and the hot air is delivered at the same time, integrating the hot air circulation and vacuum suction modes to achieve rapid drying of the probe after cleaning and avoid secondary pollution.

[0017] Optionally, the high-pressure spray pipe extends out of the outer layer of the cleaning chamber and is connected to a distilled water pipe, which is connected to a water storage tank and also to a pH adaptive buffer tank.

[0018] By adopting the above technical solution, the water storage tank provides clean water to the high-pressure spray pipe, and the pH adaptive buffer tank delivers pH adaptive buffer to the distilled water pipeline, thereby making probe cleaning faster, more efficient and comprehensive to adapt to different types of contamination.

[0019] Optionally, the cleaning chamber is made of corrosion-resistant titanium alloy.

[0020] By adopting the above technical solutions, the corrosion-resistant design can cope with strong acid / alkaline slurry environments with pH 2-12, and is suitable for complex working conditions in salt lake brine.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. By setting cleaning chambers and cleaning covers on both sides of the probe, the probe is held by a clamping plate. Under the action of the driving mechanism, the cleaning cover can move closer to the cleaning chamber, thereby pushing the clamping plate to move the probe into the cleaning chamber. During the movement, the clamping plate is inserted into the limiting groove. When the clamping plate is at its deepest point in the limiting groove, the cleaning cover is in contact with the cleaning chamber, thus placing the probe in a relatively sealed space. By turning on the ultrasonic generator and the high-pressure spray head, the crystals and viscous deposits on the probe can be physically cleaned separately. The waste liquid after cleaning is discharged from the waste liquid discharge pipe, achieving efficient and intelligent cleaning, ensuring the safety of personnel and the accuracy of monitoring data.

[0023] 2. By dividing the sidewalls of the cleaning chamber into inner and outer layers, and installing a high-pressure spray pipe in the middle layer,

[0024] Multiple high-pressure spray heads can be installed along the direction of the high-pressure spray pipe. These multiple high-pressure spray heads can come from different directions and angles, thereby achieving all-round, multi-angle cleaning probes, and further realizing quick, convenient and efficient cleaning.

[0025] 3. By connecting a vacuum pump to the bottom of the cleaning chamber and a hot air delivery pipe to the top of the cleaning chamber, the hot air circulation and vacuum suction modes are integrated to achieve rapid drying of the probe after cleaning and avoid secondary contamination.

[0030] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0031] This application discloses an automatic cleaning device for an online monitoring probe of slurry in a boric acid acidification process. (Refer to...) Figure 1 An automatic cleaning device for an online monitoring probe of slurry in a boric acid acidification process includes a probe 1, which is fixedly installed on one side of the slurry.

Several high-pressure spray heads 32 are fixedly installed on the inner wall, sides, and top wall of the cleaning chamber 2.

[0032] Reference Figure 1 , Figure 2 and Figure 3The cleaning chamber 2 has a double-layered sidewall structure. A high-pressure spray pipe 31 is installed in the middle layer of the sidewall. The high-pressure spray pipe 31 is meandering and surrounds the outer wall of the inner layer of the cleaning chamber 2. Several high-pressure spray heads 32 are installed on the high-pressure spray pipe 31. Several perforations 23 are opened in the inner layer of the sidewall of the cleaning chamber 2. The size of the perforations 23 is adapted to the outer diameter of the high-pressure spray heads 32. The high-pressure spray heads 32 pass through the perforations 23 and face the center of the cleaning chamber 2. The high-pressure spray pipe 31 passes through the outer layer of the cleaning chamber 2 and is connected to a distilled water pipe 12. The distilled water pipe 12 is connected to a water storage tank 13, which continuously provides water to the high-pressure spray pipe 31. In order to clean the probe 1 more thoroughly, the distilled water pipe 12 is also connected to a pH adaptive buffer tank 14. The pH adaptive buffer tank 14 periodically introduces pH adaptive buffer into the distilled water pipe 12 to maintain the original pH value of the probe 1.

[0033] Reference Figure 1 and Figure 2 An ultrasonic oscillating rod 41 is fixedly installed on both sides of the top wall of the cleaning chamber 2. An ultrasonic generator 42 is installed above the cleaning chamber 2, and the ultrasonic generator 42 is electrically connected to the ultrasonic oscillating rod 41.

Several waste liquid inlet holes 24 are opened in the inner layer of the bottom of the cleaning chamber 2, and a waste liquid discharge hole 25 is opened in the outer layer of the bottom of the cleaning chamber 2. The height of the inner surface of the outer layer of the bottom of the cleaning chamber 2 is higher than the height of the waste liquid discharge hole 25, so that all the waste liquid can fall into the waste liquid discharge hole 25. The waste liquid discharge hole 25 is connected to the waste liquid discharge pipe 5, and the waste liquid discharge pipe 5 is connected to the electrodialysis device 6, thereby realizing the separation and recovery of boric acid and lithium ions in the waste liquid and reducing environmental pollution.

[0034] The cleaning chamber 2 has an opening 21 on the side facing the probe 1. A cleaning cover 7 is provided on the other side of the probe 1. A clamping plate 8 is vertically provided on the side of the cleaning cover 7 facing the opening 21. The clamping plate 8 is vertically positioned and has a "U"-shaped groove 81 at its lower end. The probe 1 is placed in the "U"-shaped groove 81. A drive mechanism 9 is provided on the side of the cleaning cover 7 away from the clamping plate 8 to move the probe 1 into the cleaning chamber 2. A limiting groove 22 is provided on one side of the cleaning chamber 2. The limiting groove 22 communicates with the opening 21. The clamping plate 8 and the limiting groove 22 are located on the same horizontal line. The clamping plate 8 can be inserted parallel into the limiting groove 22 and fits against the groove wall of the limiting groove 22. The size of the cleaning cover 7 is adapted to the opening 21 and fits against the opening 21.

[0035] The drive mechanism 9 includes a fixed frame 91 and a cylinder 92. The fixed frame 91 is fixedly installed on the ground or on a certain device next to the slurry. The fixed part of the cylinder 92 is fixedly installed on the fixed frame 91. The moving part of the cylinder 92 is fixedly connected to the cleaning cover plate 7, thereby realizing the movement of the cleaning cover plate 7 towards or away from the cleaning chamber 2.

[0036] To ensure rapid drying of probe 1 after cleaning and to avoid secondary contamination, a vacuum pump 10 is connected to the bottom of the cleaning chamber 2, and a hot air delivery pipe 11 is connected to the top of the cleaning chamber 2. When drying probe 1, the air in the cleaning chamber 2 can be extracted by the vacuum pump 10, and then hot air can be introduced. Subsequently, the vacuum pump is continuously evacuated while hot air is introduced, which can quickly dry the cleaned probe 1.

[0037] To prevent strong acids and alkalis from corroding the inner wall of the cleaning chamber 2, the inner wall of the cleaning chamber 2 is made of corrosion-resistant titanium alloy.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
