[0002] Organic chemical raw materials are common industrial raw materials with important applications in many industries such as chemical, food, and pharmaceutical. During the production process, it is necessary to sample and test their liquids to ensure product quality. However, these raw materials have characteristics such as high melting point and easy solidification. Traditional sampling devices, such as sampling bottles and sampling test tubes, are prone to problems such as sample condensation and inaccurate sampling. Some of these devices have heat-insulating properties, but their temperature will gradually decrease over time, making it impossible to adjust the temperature according to the melting point and other material properties of the sample.

[0003] Now, a novel sampling device that can keep the temperature warm and isolate the air is proposed to solve the above problems. Utility Model Content

[0006] The temperature control component includes an inner shell, which is located inside an outer shell. The inner wall of the outer shell is covered with a flame-retardant and heat-insulating cotton lining, and the outer wall of the inner shell is covered with a graphite thermally conductive foam lining. A heating wire is sandwiched between the flame-retardant and heat-insulating cotton lining and the graphite thermally conductive foam lining.

[0007] As a further technical solution of this utility model, the vertical center lines of the outer shell and the inner shell coincide, and the inner shell and the discharge valve are internally connected.

[0008] As a further technical solution of this utility model, the heating wire and the outer wall of the graphite thermally conductive foam lining are tightly bonded together, and there is a distance between the flame-retardant thermal insulation cotton lining and the heating wire.

[0009] As a further technical solution of this utility model, the flame-retardant thermal insulation cotton lining completely covers the graphite thermally conductive foam lining, and the PLC controller and heating wire are electrically connected.

[0010] As a further technical solution of this utility model, the inner shell, the displacement exhaust port, and the displacement air inlet are internally connected, and the top of the displacement air inlet is lower than the bottom of the displacement exhaust port.

An electric cylinder is movably installed between the trolley frame and the scissor lift. The position and size of the limit screw correspond one-to-one with the position and size of the screw hole of the top flange of the sampling valve. The PLC controller, the thin-film pressure sensor, and the electric cylinder are electrically connected.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the sampling device that can keep the temperature warm and isolate the air not only realizes the function of adjusting the temperature according to the physical properties of the sample, but also realizes the function of facilitating the isolation of air, and also realizes the function of facilitating the connection with valve flanges.

[0013] (1) By setting up an outer shell, thermometer, inner shell, flame-retardant insulation cotton lining, graphite thermal conductive foam lining and electric heating wire, when in use, the sampling valve is connected to the reserved sampling valve of the workshop pipeline. Liquid material flows into the inner shell along the sampling valve. Before sampling, the electric heating wire is turned on by the PLC controller for preheating. The electric heating wire is energized and heats up. The graphite thermal conductive foam lining makes the inner shell reach a suitable temperature. As the material enters the inner shell, the thermometer keeps real-time monitoring of the temperature. The PLC controller controls the opening and closing of the electric heating wire and the power according to the feedback temperature parameters. The flame-retardant insulation cotton lining can prevent the rapid loss of heat and keep the inner shell at the best temperature to ensure the state of the sample. During testing, part of the sample can be taken out through the discharge valve for testing. The function of adjusting the temperature according to the physical properties of the sample is realized.

[0014] (2) By setting up a displacement exhaust port, a first ball valve, a displacement air inlet and a second ball valve, when in use, the gas in the inner shell can be replaced according to the different properties of the material. The gas source is connected to the second ball valve, the first ball valve is connected to the exhaust collection pipe, and the second ball valve is opened. The corresponding inert gas enters the inner shell along the displacement air inlet and the gas inside is discharged through the displacement exhaust port. This maximizes the preservation of the original state of the material and prevents oxidation or deterioration caused by air, thus realizing the function of easy air isolation.

[0015] (3) By setting up a rubber sealing ring, a limit screw, a locking nut, a sensor wiring port, a diaphragm pressure sensor, a scissor lift, and an electric cylinder, when docking valves, the sampling valve and the reserved valve on the pipeline are roughly aligned. The rubber sealing ring is fixed to the sampling valve by the limit screw and the locking nut. As the electric cylinder extends, the entire support plate is raised by the scissor lift, and the sampling valve moves up synchronously. The limit screw is inserted into the flange bolt hole of the upper valve until the rubber sealing ring is pressed, increasing the sealing of the docking position of the two sets of valves. As the rubber sealing ring is squeezed, the diaphragm pressure sensor is subjected to force and feeds the pressure value back to the PLC controller. When the pressure value reaches the preset threshold, the electric cylinder stops extending. At this time, the docking is completed. The valve is limited by the limit screw and will not be misaligned. The sealing ring enhances the sealing. At this time, the valve can be opened for sampling, realizing the function of easy docking of valve flanges. Attached Figure Description

The inner wall of the outer shell 7 is covered with a flame-retardant and heat-insulating cotton lining 14, and the outer wall of the inner shell 13 is covered with a graphite thermally conductive foam lining 15. A heating wire 16 is sandwiched between the flame-retardant and heat-insulating cotton lining 14 and the graphite thermally conductive foam lining 15.

[0025] The vertical center lines of the outer shell 7 and the inner shell 13 are aligned. The inner shell 13 and the discharge valve 8 are internally connected. The heating wire 16 and the outer wall of the graphite thermally conductive foam liner 15 are tightly attached. There is a distance between the flame-retardant insulation cotton liner 14 and the heating wire 16. The flame-retardant insulation cotton liner 14 completely covers the graphite thermally conductive foam liner 15. The PLC controller 4 and the heating wire 16 are electrically connected for convenient heat preservation and temperature control.

[0026] Specifically, such as Figure 1 and Figure 2 As shown, before sampling, the heating wire 16 is preheated by turning on the PLC controller 4. The heating wire 16 generates heat, and the graphite thermally conductive foam lining 15 brings the inner shell 13 to a suitable temperature. As the material enters the inner shell 13, the thermometer 10 keeps real-time monitoring of the temperature. The PLC controller 4 controls the opening and closing of the heating wire 16 and its power according to the feedback temperature parameters. The flame-retardant thermal insulation cotton lining 14 can prevent the rapid loss of heat and keep the inner shell 13 at the optimal temperature.

[0028] Specifically, such as Figure 1 and Figure 2 As shown, the gas source is connected to the second ball valve 20, the first ball valve 18 is connected to the exhaust collection pipe, the second ball valve 20 is opened, and the corresponding inert gas enters the inner shell 13 along the displacement inlet 19, and the gas inside is discharged through the displacement exhaust port 17, so as to maximize the preservation of the original state of the material and prevent oxidation or deterioration caused by air.

[0029] A rubber sealing ring 21 is provided above the sampling valve 11. A limit screw 22 is vertically fixed inside the rubber sealing ring 21. A locking nut 23 is sleeved on the bottom of the limit screw 22. A sensor wiring port 24 is provided on the left side of the rubber sealing ring 21. Multiple sets of diaphragm pressure sensors 25 are fixedly installed inside the rubber sealing ring 21. A scissor lift 26 is movably connected between the trolley frame 1 and the pallet 5. An electric cylinder 27 is movably installed between the trolley frame 1 and the scissor lift 26. The position and size of the limit screw 22 correspond one-to-one with the position and size of the screw hole of the flange at the top of the sampling valve 11. The PLC controller 4, the diaphragm pressure sensor 25, and the electric cylinder 27 are electrically connected to facilitate valve docking.

[0030] Specifically, such as Figure 3 , Figure 4 and Figure 5As shown, during valve docking, the sampling valve 11 and the reserved valve on the pipeline are roughly aligned. The rubber sealing ring 21 is fixed to the sampling valve 11 by the limiting screw 22 and the locking nut 23. As the electric cylinder 27 extends, the support plate 5 is raised by the scissor lift 26, and the sampling valve 11 moves upward synchronously. The limiting screw 22 is inserted into the flange bolt hole of the upper valve until the rubber sealing ring 21 is pressed, increasing the sealing of the docking position of the two sets of valves. As the rubber sealing ring 21 is squeezed, the diaphragm pressure sensor 25 is subjected to force and feeds back the pressure value to the PLC controller 4. When the pressure value reaches the preset threshold, the electric cylinder 27 stops extending. At this time, the docking is completed. The valve is limited by the limiting screw 22 and will not be misaligned. The sealing ring enhances the seal. At this time, the valve can be opened for sampling.

[0031] Working principle: When using this utility model, firstly, the sampling valve 11 is connected to the reserved sampling valve of the workshop pipeline. The liquid material flows into the inner shell 13 along the sampling valve 11. Before sampling, the heating wire 16 is turned on by the PLC controller 4 for preheating. The heating wire 16 is energized and heats up. The graphite thermally conductive foam lining 15 makes the inner shell 13 reach a suitable temperature. As the material enters the inner shell 13, the thermometer 10 keeps real-time monitoring of the temperature. The PLC controller 4 controls the opening and closing of the heating wire 16 and the power according to the feedback temperature parameters. The flame-retardant heat-insulating cotton lining 14 can prevent the rapid loss of heat and keep the inner shell 13 at the optimal temperature to ensure the state of the sample. During testing, a portion of the sample can be taken out through the discharge valve 8 for testing. Depending on the properties of the material, the gas in the inner shell 13 can be replaced. The gas source is connected to the second ball valve 20, and the first ball valve 18 is connected to the exhaust collection pipe. When the second ball valve 20 is opened, the corresponding inert gas enters the inner shell 13 along the replacement inlet 19, and the gas inside is discharged through the replacement exhaust port 17, so as to maximize the preservation of the original state of the material and prevent oxidation or deterioration caused by air. When docking the valves, the sampling valve 11 and the reserved valve on the pipeline are roughly aligned. The rubber sealing ring 21 is fixed to the sampling valve 11 by the limiting screw 22 and the locking nut 23. As the electric cylinder 27 extends, the support plate 5 is raised by the scissor fork 26, and the sampling valve 11 moves upward in sync. The limiting screw 22 is inserted into the flange bolt hole of the upper valve until the rubber sealing ring 21 is pressed, which increases the sealing of the docking position of the two sets of valves. As the rubber sealing ring 21 is squeezed, the diaphragm pressure sensor 25 is subjected to force and feeds back the pressure value to the PLC controller 4. When the pressure value reaches the preset threshold, the electric cylinder 27 stops extending. At this time, the docking is completed. The valve is limited by the limiting screw 22 and will not be misaligned. The sealing ring enhances the seal. At this time, the valve can be opened for sampling.
