Description

Technical Field

[0001] This invention relates to the field of distillation apparatus technology, and more specifically, to a distillation apparatus based on image recognition. Furthermore, this invention also relates to an alkylmercury distillation apparatus comprising the aforementioned method. Background Technology

[0002] Some samples (such as those with high chloride ion or organic matter content) cannot be directly used for the detection of alkyl mercury content and need to be distilled to remove or reduce interfering factors before detection.

[0003] Current alkylmercury distillation equipment uses heating rods or heating plates for heating the sample, with aluminum or graphite as the heat transfer medium. The cooling system uses an ice-water bath or cooling pads, and both heating and cooling sections are temperature-controlled as a whole. The distillate receiving flask has graduations for direct observation of the distillate volume. Once the distillation endpoint is reached, the connecting tube is manually disconnected, and heating continues until all samples have been distilled. While all distillation flasks in current alkylmercury distillation apparatuses are heated synchronously, the actual heat transfer efficiency of each flask cannot be exactly the same. The distillation volume of the same batch of samples can differ by 3-5 mL, and this difference is even greater for samples with different organic matter contents. Current alkylmercury distillation apparatuses require all samples to reach the distillation endpoint before stopping heating. For samples that reach the endpoint first, the connecting tube in the receiving flask must be removed first, but the flask continues to be heated, causing droplets to splash from the connecting tube, potentially contaminating other samples or splashing onto the operator. Therefore, personnel are required to monitor the process near the distillation endpoint to prevent over-distillation that could render the sample unusable and to avoid injury to the operator.

[0004] In conclusion, how to improve the automation level of distillation equipment is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] In view of this, the object of the present invention is to provide an image recognition-based distillation apparatus that has a higher degree of automation than existing alkyl mercury distillation equipment.

[0006] Another object of the present invention is to provide an alkylmercury distillation apparatus including the above-described distillation device.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A distillation apparatus based on image recognition, comprising:

[0009] The heat-insulating base has at least ten grooves, and an electric heating socket is installed in each groove;

[0010] Distillation flasks, multiple of which are located in recesses, are used to store the liquid to be distilled. The upper end of the distillation flask is equipped with a cap, and a connecting tube is inserted into the cap. An electric heating socket is used to heat and distill the liquid to be distilled.

[0011] A cooling base is provided with at least ten storage tanks, each containing a receiving bottle, and the other end of a connecting pipe is inserted into the receiving bottle.

[0012] A camera is positioned above the cooling base and is used to capture images of the liquid level inside the receiving bottle;

[0013] The control system connects the electric heating socket to the camera. The camera transmits the captured images to the control system, which controls the opening and closing of the electric heating socket.

[0014] Preferably, a heat-conducting tube is provided in the groove, the distillation flask is placed inside the heat-conducting tube, and a heating plate is provided at the lower end of the heat-conducting tube. The heating plate is set against the electric heating socket and used to heat the heat-conducting tube. The heat-conducting tube is used to achieve uniform heating of the distillation flask.

[0015] Preferably, a temperature sensor is provided at the bottom of the heat pipe, an upward-extending perforation is provided on the bottom surface of the heat pipe, and a downward-extending perforation is provided in the groove. The two ends of the temperature sensor are respectively inserted into the heat pipe and the perforation in the groove. The temperature sensor is used to detect the temperature of the heat pipe.

[0016] Preferably, the cooling base is provided with a lifting assembly, and the connecting pipe is located on the lifting assembly. The lifting assembly is used to drive the connecting pipe to move up and down.

[0017] Preferably, the cooling base is provided with a partition plate, which is set perpendicular to the upper surface of the cooling base and divides the receiving bottle into two groups. The angle between the central axis of the camera and the partition plate is an acute angle.

[0018] Preferably, at least two cameras are provided and located on both sides of the partition.

[0019] Preferably, the receiving bottle contains cooling liquid, and one end of the connecting tube is inserted into the receiving bottle below the surface of the cooling liquid.

[0020] An alkylmercury distillation apparatus includes an image recognition-based distillation device, wherein the image recognition-based distillation device is any of the image recognition-based distillation devices described above.

[0021] This invention provides an image recognition-based distillation apparatus. An electric heating socket, located within a groove in an insulated base, engages with a distillation flask to heat and distill the liquid inside. The upper end of the distillation flask is fitted with a cap and a connecting tube. The other end of the connecting tube is inserted into a receiving flask mounted on a cooling base. The liquid to be distilled enters the receiving flask through the connecting tube for collection. A camera captures the liquid level in the receiving flask and sends the image to a control system. The control system determines whether the liquid level in the receiving flask has reached a preset height. If the liquid level reaches the preset height, the control system lowers the heating temperature of the electric heating base, thereby slowing down the distillation speed. This allows multiple receiving flasks to be distilled simultaneously. The entire process requires no human intervention, improving the automation level of the distillation apparatus and preventing operator injury. Attached Figure Description

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] The core of this invention is to provide a distillation device based on image recognition, which requires no manual operation and has a higher degree of automation.

[0031] Another core aspect of this invention is to provide an alkylmercury distillation apparatus that includes the above-described distillation device.

[0032] This application provides an image recognition-based distillation apparatus, comprising: a heat-insulating base 1, with at least ten grooves on the heat-insulating base 1, and an electric heating socket in each groove; a distillation flask 2, having multiple flasks all located within the grooves, the flasks 2 for storing the liquid to be distilled, the upper end of the flasks 2 having a cap, and a connecting tube 3 inserted into the cap, the electric heating socket for heating and distilling the liquid to be distilled; a heating element 4, located at the bottom of the flasks 2, abutting against the electric heating socket and used for heating and distilling the liquid to be distilled; a cooling base 5, having at least ten storage tanks on the cooling base 5, each storage tank containing a receiving bottle 6, the other end of the connecting tube 3 inserted into the receiving bottle 6; a camera 7, located above the cooling base 5 and used to capture the liquid level in the receiving bottle 6; and a control system, with a signal connected to the electric heating socket and the camera 7, the camera 7 transmitting the captured results to the control system, the control system controlling the opening and closing of the electric heating socket.

[0033] The heat-insulating base 1 has ten evenly distributed grooves to ensure that the multiple distillation flasks 2 do not interfere with each other during the heating process; the receiving bottle 6 is a transparent bottle.

[0034] For details, please refer to the appendix. Figure 1 With appendix Figure 4Each groove is equipped with an electric heating socket, which can be individually controlled by the control system. Multiple distillation flasks 2 are placed in the groove and heated by the electric heating sockets, allowing the liquid to be distilled in the flasks 2 to be distilled into the receiving bottle 6 for collection. The liquid level in the multiple receiving bottles 6 is captured and recorded by a camera 7, and the liquid level information of the receiving bottles 6 is transmitted to the control system. When the liquid level in one receiving bottle 6 reaches a preset position, the control system controls the electric heating socket below the corresponding distillation flask 2 to reduce the heating temperature. Generally, the distillation temperature of the liquid to be distilled is 125℃ to 130℃, and the heating temperature of the electric heating socket is controlled to 105℃, thereby reducing the distillation rate in that distillation flask 2. The distillation rate of the other distillation flasks 2 remains unchanged, so that the distillation process of multiple distillation flasks 2 can be completed simultaneously. During this process, the distillation flasks 2 are not overheated, preventing liquid splashing and ensuring the safety of the operator. Moreover, this process can be fully automated, greatly improving the automation level of the device.

[0035] Based on the above embodiment, a heat-conducting pipe 8 is provided in the groove, the distillation flask 2 is disposed in the heat-conducting pipe 8, and a heating plate 4 is provided at the lower end of the heat-conducting pipe 8. The heating plate 4 is abutted against the electric heating socket and used to heat the heat-conducting pipe 8. The heat-conducting pipe 8 is used to achieve uniform heating of the distillation flask 2.

[0036] For details, please refer to the appendix. Figure 2 With appendix Figure 3 The heat-conducting pipe 8 is located in the groove, and the distillation flask 2 is located inside the heat-conducting pipe 8 and can move up and down along the heat-conducting pipe 8 to realize the disassembly or installation of the distillation flask 2. The heat-conducting pipe 8 is made of a material with good thermal conductivity. The heat-conducting pipe 8 is located on the outer periphery of the distillation flask 2. By wrapping the distillation flask 2 with the heat-conducting pipe 8, the distillation flask 2 can be heated evenly, preventing the unsatisfactory distillation effect caused by uneven heating.

[0037] Based on the above embodiment, a temperature sensor 11 is provided at the bottom of the heat pipe 8, an upwardly extending perforation is provided on the bottom surface of the heat pipe 8, and a downwardly extending perforation is provided in the groove. The two ends of the temperature sensor 11 are respectively inserted into the heat pipe 8 and the perforation in the groove. The temperature sensor 11 is used to detect the temperature of the heat pipe 8.

[0038] Specifically, a temperature sensor 11 is installed at the bottom of the heat pipe 8. The middle part of the temperature sensor 11 is a disc-shaped part. Both the upper and lower surfaces of the disc-shaped part are provided with protrusions. The two protrusions are respectively inserted into the through holes in the groove of the heat insulation base 1 and the through holes at the bottom of the heat pipe 8. The temperature of the heat pipe 8 is detected by the temperature sensor 11 to determine the heating temperature of the distillation flask 2.

[0039] Based on the above embodiment, the cooling base 5 is provided with a lifting component 9, and the connecting pipe 3 is provided on the lifting component 9. The lifting component 9 is used to drive the connecting pipe 3 to move up and down.

[0040] Specifically, the lifting assembly 9 on the cooling base 5 is a C-shaped part, and the two ends of the lifting assembly 9 extend downward. Multiple L-shaped protrusions are provided on both sides of the middle part of the lifting assembly 9, and the multiple L-shaped protrusions extend downward. The connecting pipe 3 is fixed to the lifting assembly 9 so that the connecting pipe 3 can complete the lifting and lowering movement with the lifting assembly 9. After the distillation process is completed, the connecting pipe 3 is pulled out of the receiving bottle 6 by the lifting assembly 9 to complete the sealing of the receiving bottle 6. In addition, the connecting pipe 3 should be pulled out immediately by the lifting assembly 9 after the distillation is completed to prevent liquid from being sucked back into the distillation bottle 2.

[0041] Based on the above embodiment, the cooling base 5 is provided with a partition plate 10. The partition plate 10 is set perpendicular to the upper surface of the cooling base 5 and divides the receiving bottle 6 into two groups. The angle between the central axis of the camera 7 and the partition plate 10 is an acute angle. The angle between the central axis of the camera 7 and the upper surface of the cooling base 5 is an acute angle.

[0042] Specifically, the partition plate 10 is a plate-shaped piece and is perpendicular to the upper surface of the cooling base 5. At least five receiving bottles 6 are evenly distributed on both sides of the partition plate 10. A camera 7 is installed at the receiving bottle 6 at the outermost edge. The angle between the central axis of the camera 7 and the partition plate 10 and the upper surface of the cooling base 5 is an acute angle, so that the camera 7 can capture the liquid level in the distillation flask 2 which is lower than the cooling base 5.

[0043] Based on the above embodiment, at least two cameras 7 are provided and located on both sides of the partition plate 10.

[0044] Specifically, cameras 7 are provided on both sides of the partition plate 10. Both cameras 7 are located on the same side of the cooling base 5. The distillation flasks 2 on both sides of the partition plate 10 are photographed by at least two cameras 7 to ensure that the liquid level in the flasks can be captured by the cameras 7.

[0045] Optionally, four cameras 7 can be set up, each located at one of the four corners of the cooling base 5, to ensure that when there are a large number of distillation flasks 2, the liquid level in all distillation flasks 2 can be clearly captured.

[0046] Based on the above embodiment, the receiving bottle 6 is filled with cooling liquid, and one end of the connecting pipe 3 is inserted into the receiving bottle 6 below the surface of the cooling liquid.

[0047] Specifically, the temperature of the cooling liquid is 0℃ to 5℃. By inserting one end of the connecting pipe 3 into the receiving bottle 6 below the surface of the cooling liquid, the loss of gaseous distillate can be effectively avoided, thus improving equipment safety.

[0048] In addition to the image recognition-based distillation apparatus described above, the present invention also provides an alkylmercury distillation apparatus including the distillation apparatus disclosed in the above embodiments. The structure of the other parts of the alkylmercury distillation apparatus is described in the prior art and will not be repeated here.

[0049] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
