Description

Technical Field

[0001] This application relates to the field of organic carbon content determination, and particularly to a fully automatic multi-position solid combustion sampling device. Background Art

[0002] There are a wide variety of organic carbons, large in quantity and widespread in distribution. They can be found in air, surface water, domestic sewage, industrial wastewater, soil, sediment, and residues from organic chemical production. The determination methods for organic matter include biochemical oxygen demand (BOD), chemical oxygen demand (COD), total oxygen demand (TOD), ultraviolet absorbance (UVASM), and total organic carbon (TOC). The content of solid organic carbon can be determined by the total organic carbon method.

[0003] This determination method is carried out by burning the sample in a combustion tube and detecting the products. The sample is placed in a sample chamber, and the material is transported by placing the sample chamber into the feeding port on the combustion tube. Since there are many types of samples and the composition of each sample is different, each determination requires staff to weigh and transport the sample. However, due to the small feeding port, the sample is likely to tilt when transported to the feeding port, resulting in sample spillage, which affects both the sample transport efficiency and the sample transport accuracy.

[0006] In this application, the combustion tube is placed on a platform, the sample is placed in a sample chamber, the sample chamber is placed on the platform, and an automatic conveying assembly is also provided on the platform. The clamping plate in the automatic conveying assembly can clamp the sample chamber and then convey the sample chamber to the feeding port of the combustion tube through a three-dimensional conveying table. The clamping plate is small in volume and stable in clamping, and can enter and exit more conveniently from the feeding port, so that the sample can be stably transported, avoiding the shaking caused by manual transportation. The transportation speed of the three-dimensional conveying table is stable, and samples with larger volume and weight can be transported at the same time, which can effectively improve the sample conveying efficiency and thus improve the detection efficiency.

[0007] In some embodiments of this application, the three-dimensional conveying table includes a first-direction conveying table, a second-direction conveying table, and a height conveying table.

The sealing seat is disposed at the feed port, and the sealing seat is hermetically connected to the combustion tube. The top of the sealing seat forms a plane parallel to the surface of the sealing plate, and the sealing seat abuts against the sealing plate. The sealing seat can make the upper surface of the feed port form a plane, which is convenient for the sealing seat to fit with the sealing plate, thereby improving the sealing effect.

[0026] There are a wide variety, large quantity, and extensive distribution of organic carbon. Their traces can be found in air, surface water, domestic sewage, industrial wastewater, soil, sediment, and residues from organic chemical production. The determination methods of organic matter include biochemical oxygen demand (BOD), chemical oxygen demand (COD), total oxygen demand (TOD), ultraviolet absorbance (UVASM), and total organic carbon (TOC). The content of solid organic carbon can be determined by the method of total organic carbon.

[0027] This measurement method is carried out by burning the sample in a combustion tube and detecting the products. The sample is placed in a sample chamber, and the material is transported by placing the sample chamber into the feeding port on the combustion tube. Since there are many types of samples and the composition of each sample is different, every time a measurement is carried out, the staff needs to weigh and transport the sample. However, due to the small size of the feeding port, when the sample is transported to the feeding port, it is easy to tilt and cause the sample to spill out, which affects the sample transportation efficiency and the sample transportation accuracy at the same time.

[0028] Therefore, please refer to Figure 1 , this application provides a fully automatic multi-position solid combustion sampling device, including a platform 1, a combustion tube 2, a sample chamber 3, a sample, a combustion tube sealing component 4, and an automatic transportation component 5.

[0029] Please refer to Figure 1 , the platform 1 can be a fixed platform 1, such as a constructed cement building, or it can be a metal platform 1, such as a steel plate, a grid frame, or other table surfaces that can play a supporting role. The platform 1 can have various sizes and be matched with combustion tubes 2 of different sizes to detect different samples; the upper surface of the platform 1 can be a plane, and this plane can be a complete plane or can be provided with a notch.

[0030] Please refer to Figure 1 , the combustion tube 2 is arranged on the platform 1 along a direction parallel to the surface of the platform 1, the extending direction of the combustion tube 2 is the first direction, and a feeding port 21 (as shown in Figure 2 ) is arranged on the side of the combustion tube 2 away from the platform 1. The combustion tube 2 usually uses a glass tube, and the combustion tube 2 and the platform 1 can be fixedly connected through an ear plate bracket or can be installed through other installation structures, so that the position of the combustion tube 2 is fixed; at the same time, for the convenience of disassembly and cleaning, the combustion tube 2 and the platform 1 can adopt a detachable connection.

[0031] Please refer to Figure 1 , since the structure at the feeding port 21 of the combustion tube 2 is usually complex and inconvenient to clean, the combustion usually takes place in other areas inside the tube. At this time, a pushing and feeding structure can be arranged inside the combustion tube 2 to transport the sample to the designated combustion area; at this time, the combustion tube 2 can also be set in multiple sections, and the feeding port 21 can be located on the part of the combustion tube 2 on the platform 1.

[0032] Please refer to Figure 1 , the sample chamber 3 is used to hold the sample. A plurality of sample chambers 3 are provided, and the plurality of sample chambers 3 are arranged at intervals on the platform 1. All the sample chambers 3 are arranged on the same side of the combustion tube 2 and are spaced apart from the combustion tube 2. The sample chamber 3 can be made of metal or non-metal. The material of the sample chamber 3 can be selected as glass or other materials. An opening can be arranged on the upper side of the sample chamber 3 for taking and placing the sample.

[0035] Please refer to Figure 1 , the automatic conveying assembly 5 is arranged on the platform 1. The automatic conveying assembly 5 includes a three-dimensional conveying table 51 and clamping plates 52. The free end of the three-dimensional conveying table 51 is connected to the clamping plates 52. The clamping plates 52 can clamp the sample chamber 3 and move the sample chamber 3 into the feed port 21 through the three-dimensional conveying table 51. The three-dimensional conveying table 51 is a three-dimensional conveying table, that is, it has the ability of spatial conveyance and can convey the clamping plates 52 to any place in the space inside the three-dimensional conveying table 51.

[0036] Please refer to Figure 1 , the clamping plates 52 can be electric clamping plates 52, that is, a motor is arranged inside, and the distance between the clamping plates 52 is controlled by the motor to increase or decrease to clamp the above-mentioned sample chamber 3; the clamping plates 52 can be two parallel flat plates or other structures with a clamping effect; the clamping plates 52 and the three-dimensional conveying table can be fixedly connected, such as bolt connection or welding.

The transportation speed of the three-dimensional conveying table 51 is stable, and at the same time, it can transport samples with larger volume and weight, which can effectively improve the conveying efficiency of the sample and thus improve the detection efficiency.

[0038] Please refer to Figure 1, Exemplarily, the first direction and the second direction can be any two mutually perpendicular directions parallel to the plane of the platform 1. The first direction and the second direction can be parallel to the edge of the platform 1 or can be set at a certain angle.

[0040] Please refer to Figure 1 , In some examples, the opening of the feeding port 21 can be slightly larger than the sample bin 3, and the opening of the feeding port 21 can be equal to or larger than the combined volume and cross-sectional area of the sample bin 3 after being clamped by the clamping plate 52, so as to facilitate the sample bin 3 to enter the combustion tube 2.

[0041] In some examples, a corresponding pressing structure can also be provided on the sealing plate 41, so that after the sealing plate 41 slides to the feeding port 21 to close the feeding port 21, pressure is applied to the sealing plate 41 to make the sealing effect better.

[0042] Please refer to Figure 1 , In some examples, the three-dimensional conveying platform 51 includes a first-direction conveying platform 511, a second-direction conveying platform 512, and a height conveying platform 513.

[0043] The first-direction conveying platform 511, the second-direction conveying platform 512, and the height conveying platform 513 in the three-dimensional conveying platform 51 can enable the clamping plate 52 to move along the mutually perpendicular first direction, second direction, and height direction, so that the sample bin 3 can move on the platform 1 and be conveyed into the combustion tube 2.

[0044] In some examples, the movement direction of the mobile end on the first-direction conveying platform 511 can be the first direction, the movement direction of the mobile end on the second-direction conveying platform 512 can be the second direction, and the movement direction of the mobile end of the height conveying platform 513 can be the height direction; at this time, the first direction, the second direction, and the height direction can form a spatial coordinate system.

[0045] In some other examples, the included angle between the first direction and the second direction can also be other angles, such as between 75° and 89°. At this time, the clamping plate 52 can also move freely within this space.

[0046] In some examples, the moving ends on the first-direction conveyor 511, the moving ends on the second-direction conveyor 512, and the moving ends of the height conveyor 513 can all be sliders or the moving ends of linear motors, or can also be the binding blocks on the traction, so as to drive the actions of corresponding objects through the movement of the moving ends.

[0047] Please refer to Figure 1 , in some examples, the first-direction conveyor 511, the second-direction conveyor 512, and the height conveyor 513 are all stepper motors 53 and ball screw pairs 54.

For example, the length of the first-direction conveyor 511 can be greater than the length of the second-direction conveyor 512, and the length of the first-direction conveyor 511 can be greater than the length of the height conveyor 513.

[0049] Please refer to Figure 1 , in some examples, a plurality of display stands 6 are provided on the platform 1. The height of the display stand 6 is higher than the surface of the platform 1.

[0052] Please refer to Figure 1 , in some examples, a plurality of display stands 6 are arranged in an array along the first direction and the second direction. The array arrangement of the display stands 6 can make the gaps between the sample chambers 3 close or equal, avoiding affecting other sample chambers 3 when the clamping plate 52 clamps the sample chamber 3.

[0053] In some examples, the outer surface of the sample bin 3 on the display stand 6 can be arranged in a direction parallel to the first direction or parallel to the second direction, so that the inner wall of the clamping plate 52 can be attached to at least two outer side walls of the sample bin 3, avoiding the spillage of samples when the clamping plate 52 clamps the sample bin 3.

[0054] At this time, the array direction can be the same as or similar to the arrangement direction of the sample bin 3, and a certain angular error can be set between the two, such as 5°, so as to reduce the precision and installation difficulty of the display stand 6 and the sample bin 3.
