Description

Technical Field

[0001] This utility model relates to the field of sampling cooling, and in particular to a vertical sampling water cooling device. Background Technology

[0002] The vertical sampling water-cooling device is a specialized design for the safe and accurate collection of high-temperature fluid or material samples. Its core function is to address the hazards and sample distortion associated with direct sampling of high-temperature materials. Through its built-in cooling system, it rapidly cools the material to a safe, near-room-temperature operating temperature before it enters the sampling container, significantly reducing the risk of burns, scalds, or even explosions to operators and ensuring their safety. Simultaneously, this rapid cooling process effectively "freezes" the material's state under process conditions, suppressing volatilization, vaporization, oxidation, chemical reactions, or slow phase changes that occur when high-temperature materials are exposed to air. This ensures that the obtained sample best represents the true composition and properties within the process system, providing a reliable basis for subsequent analysis, testing, and quality control. Furthermore, the vertical sampling water-cooling device improves sampling efficiency and convenience. Operators can quickly and easily collect samples during process operation without waiting for the system to cool down or wearing heavy protective clothing. Cooled samples are also easier to transfer, store, or send for testing. It also protects the sampling container, preventing ordinary glass or plastic bottles from cracking or melting due to direct contact with high temperatures. Therefore, vertical sampling water-cooling devices are indispensable key equipment for safe, reliable, and representative high-temperature sampling in industries such as chemical, petroleum, petrochemical, metallurgy, power, food, and pharmaceutical.

[0003] To improve cooling during sampling, existing technologies have designed sampling devices, such as Chinese Patent Application No. CN202320804360.1. This utility model discloses a safety sampling device for boiler water in a steam boiler, including a vertical sampling water-cooling device and a sampling bottle holder. The vertical sampling water-cooling device includes a cooler shell and a cooling pipe. The cooler shell has a top cover, a coolant inlet at the top, a first coolant outlet at the bottom, and a second coolant outlet at the bottom. The inlet of the cooling pipe is connected to the steam boiler drain pipe through a sampling pipeline, and the outlet of the cooling pipe is connected to a sampling outlet pipe. The sampling bottle holder includes a fixing groove for placing the sampling bottle and a funnel-shaped conical shell above the fixing groove. A drain pipe is provided at the bottom of the fixing groove, and the fixing groove is fixedly connected to the top cover of the vertical sampling water-cooling device by a clamp. The funnel-shaped conical shell is fixedly connected to the sampling outlet pipe by a clamp.

[0004] However, existing technologies similar to the aforementioned patents have the following problems: the existing vertical sampling water cooling devices have limited cooling capacity, high and fluctuating outlet water temperature, poor control accuracy, difficulty in meeting stricter sampling temperature requirements, and troublesome flange hole alignment during installation. Utility Model Content

[0005] To address the limitations of existing vertical sampling water-cooling devices in terms of cooling capacity and installation complexity, this invention proposes a vertical sampling water-cooling device, the technical solution of which is as follows:

[0006] A vertical sampling water-cooling device includes a cooling tank body filled with coolant and a cooling medium pipeline installed inside the cooling tank, wherein the coolant cools the cooling medium in the cooling medium pipeline.

[0007] The cooling medium pipeline is a double spiral pipeline, with one end being the cooling medium inlet and the other end being the cooling medium outlet. Both ends of the cooling medium pipeline extend parallel spirally downward from the top of the cooling tank and connect at the bottom of the cooling tank to form a passage.

[0008] The cooling tank has a coolant inlet and a coolant outlet on both sides. The coolant inlet is located at the bottom of the side of the cooling tank, and the coolant outlet is located at the top of the side of the cooling tank. The cooling tank is also equipped with a flow guide baffle to force the coolant to spiral upward from the bottom of the cooling tank to the coolant outlet.

[0009] The cooling tank is equipped with a temperature control module. The temperature control module detects the temperature of the cooling medium at the outlet. Once the temperature reaches the preset value, the module adjusts the inlet flow rate of the coolant to ensure that the outlet cooling medium temperature remains stable at the target value.

[0010] Furthermore, the cooling medium pipeline is installed on the mounting cover, and a mounting flange is coaxially provided on the outer periphery of the top of the cooling tank. A positioning through hole is provided on the outer periphery of the mounting cover, and a threaded hole is provided on the mounting flange. The mounting cover is fixed by bolts that pass through the positioning through hole and are screwed into the threaded hole, thereby sealing the cooling tank.

[0011] Furthermore, both the cooling medium inlet and outlet of the cooling medium pipeline extend vertically into the cooling tank perpendicular to the top of the mounting cover.

[0012] Furthermore, the mounting cover is provided with a positioning mechanism, including a mounting through hole perpendicular to the top surface of the mounting cover and opened on the outer periphery of the mounting cover. A mounting plate is mounted on the mounting through hole, and a spring is coaxially arranged in the mounting through hole. One end of the spring is fixedly connected to the mounting plate, and the other end is fixedly connected to a positioning pin. The positioning pin protrudes from the bottom surface of the mounting cover, and the part of the positioning pin protruding from the bottom surface of the mounting cover is hemispherical. The mounting flange is provided with a positioning groove that matches the hemispherical positioning pin.

[0013] Furthermore, the positioning pin is provided with guide protrusions on both sides, and guide grooves that cooperate with the guide protrusions along the axis of the mounting through hole are opened on both sides. The guide grooves extend upward and open on one side of the top of the mounting through hole, while the bottom of the guide grooves is not open, thus limiting the positioning pin and preventing it from falling out.

[0014] Furthermore, the cross-section of the flow guide baffle is rectangular, and the baffle is installed perpendicular to the inner wall of the cooling tank. The baffle spirals upward along the inner wall of the cooling tank with the cooling tank axis as the axial direction, and does not interfere with the cooling medium pipeline.

[0015] Furthermore, the coolant inlet and coolant outlet are two pipes extending from the cooling tank, with the coolant inlet and coolant outlet parallel to each other and tangent to the inner wall of the cooling tank.

[0016] Furthermore, the temperature control module includes a temperature sensor located at the outlet of the cooling medium and an electric regulating valve located at the inlet of the coolant. The temperature sensor and the electric regulating valve are linked. The temperature sensor detects the temperature of the cooling medium. When the temperature reaches the preset temperature, it triggers the electric regulating valve to adjust the coolant flow rate at the inlet of the coolant.

[0017] The beneficial effects of this utility model are as follows: the inlet and outlet of the cooling medium both extend parallel spirals downwards from the top and connect at the bottom. This structure prolongs the residence time of the cooling medium in the tank and increases the contact area with the coolant. The baffle spirals upwards along the inner wall, and together with the tangentially set coolant inlet and outlet, forces the coolant to spiral upwards from the bottom, forming turbulence, avoiding the stratification of hot and cold liquids, improving heat exchange uniformity, increasing heat exchange efficiency, solving the cooling dead zone problem caused by traditional straight pipe or single spiral structures, and ensuring that the temperature of the cooling medium drops uniformly. A temperature sensor is installed at the cooling medium outlet to monitor the temperature in real time. The electric regulating valve of the coolant inlet is linked to dynamically adjust the coolant flow rate. The coolant enters from the bottom and exits from the top, forming counter-current heat exchange with the cooling medium to maximize the temperature gradient. The spring and hemispherical positioning pin structure, together with the groove on the flange, realizes the rapid and accurate positioning of the installation cover. Attached Figure Description

[0022] The present invention will be further described below with reference to the embodiments and accompanying drawings:

[0023] like Figure 1 As shown, a vertical sampling water-cooling device includes a cooling tank 1 filled with coolant and a cooling medium pipeline 2 installed inside the cooling tank 1. The coolant cools the cooling medium in the cooling medium pipeline 2. The cooling medium pipeline 2 is a double-helix pipeline. The double-helix structure extends the heat exchange path and improves the cooling efficiency. One end is a cooling medium inlet 3 and the other end is a cooling medium outlet 4. Both ends of the cooling medium pipeline 2 extend parallel spirally downward from the top of the cooling tank 1 and connect at the bottom of the cooling tank 1 to form a passage. Coolant inlets 8 and coolant outlets 9 are provided on both sides of the cooling tank 1. The coolant inlets 8 are located on the bottom side of the cooling tank 1. The coolant outlet 9 is located on the top side of the cooling tank 1. High-temperature medium enters from the top, and low-temperature coolant enters from the bottom, maximizing the temperature gradient. The cooling tank 1 is equipped with a flow guide baffle 5, which forces the coolant to spiral upward from the bottom of the cooling tank 1 to the coolant outlet 9. The spiral upward flow of the coolant and the spiral downward flow of the cooling medium form a cross-flow. The cooling tank 1 is equipped with a temperature control module. The temperature control module detects the temperature of the cooling medium at the cooling medium outlet 4. After the temperature reaches the preset value, the temperature control module adjusts the inlet flow rate of the coolant inlet 8 to ensure that the temperature of the cooling medium at the cooling medium outlet 4 is stable at the target value, solving the problem of lag in manual adjustment.

[0024] like Figure 1 , Figure 2 As shown, preferably, the cooling medium pipeline 2 is installed on the mounting cover 6, and the top outer periphery of the cooling tank 1 is coaxially provided with a mounting flange 7. The outer periphery of the mounting cover 6 is provided with a positioning through hole 10, and the mounting flange 7 is provided with a threaded hole 11. The mounting cover 6 is fixed by bolts that pass through the positioning through hole 10 and are screwed into the threaded hole 11, thereby sealing the cooling tank 1.

[0025] like Figure 1 As shown, preferably, the cooling medium inlet 3 and cooling medium outlet 4 of the cooling medium pipeline 2 extend vertically into the cooling tank 1 perpendicular to the top of the mounting cover 6, which facilitates the installation of the cooling medium pipeline 2 and the mounting cover 6.

[0026] like Figure 1 , Figure 2 , Figure 3As shown, preferably, the mounting cover 6 is provided with a positioning mechanism, including a mounting through hole 12 perpendicular to the top surface of the mounting cover 6 and formed on the outer periphery of the mounting cover 6. A mounting plate 13 is mounted on the mounting through hole 12. A spring 14 is coaxially arranged in the mounting through hole 12. One end of the spring 14 is fixedly connected to the mounting plate 13, and the other end is fixedly connected to a positioning pin 15. The positioning pin 15 protrudes from the bottom surface of the mounting cover 6, and the portion of the positioning pin 15 protruding from the bottom surface of the mounting cover 6 is hemispherical. The mounting flange 7 is provided with a positioning groove 16 that matches the hemispherical positioning pin 15, so that the positioning through hole 10 of the mounting cover 6 is aligned with the threaded hole 11 of the flange.

[0027] like Figure 3 As shown, preferably, the positioning pin 15 is provided with guide protrusions 17 on both sides, and the mounting through hole 12 is provided with guide grooves 18 on both sides that cooperate with the guide protrusions 17 along the axial direction of the mounting through hole 12. The guide grooves 18 extend upward and open on one side of the top of the mounting through hole 12, and the bottom of the guide grooves 18 is not open, so as to limit the positioning pin 15 and prevent the positioning pin 15 from falling out.

[0028] like Figure 1 As shown, preferably, the cross-section of the guide baffle 5 is rectangular, and the baffle is installed perpendicular to the inner wall of the cooling tank 1. The baffle spirals upward along the inner wall of the cooling tank 1 with the axis of the cooling tank 1 as the axis, and does not interfere with the cooling medium pipeline 2. Preferably, the coolant inlet 8 and the coolant outlet 9 are two pipes extending from the cooling tank 1. The coolant inlet 8 and the coolant outlet 9 are parallel and tangential to the inner wall of the cooling tank 1, and the tangential design gives the coolant initial swirling kinetic energy.

[0029] like Figure 1 As shown, preferably, the temperature control module includes a temperature sensor 20 disposed at the cooling medium outlet 4 and an electric regulating valve 19 disposed at the coolant inlet 8. The temperature sensor 20 and the electric regulating valve 19 are linked. The temperature sensor 20 detects the temperature of the cooling medium, and when the temperature reaches a preset temperature, it triggers the electric regulating valve 19 to regulate the coolant flow rate at the coolant inlet 8. The installation method, wiring connection, control logic, and preconditions for the use of the temperature sensor 20 and the electric regulating valve 19 are all existing technologies, and therefore will not be described in detail here.

[0030] It should also be noted that if the coolant used in this invention needs to be circulated, a coolant circulation pump needs to be configured to circulate the coolant. In addition, in this invention, the connection of each pipeline, the installation of pipeline valves, and the air pressure balancing valve on the mounting cover 6 to balance the air pressure between the cooling tank 1 and the outside are not included in the innovation of this technical solution. Furthermore, the use of a circulation pump to circulate liquid is a common technical means in industry, so it will not be described in detail here.

[0031] The method of using this utility model is as follows: First, pre-cooling start-up: inject circulating coolant into the coolant inlet 8 until the liquid level overflows the top of the pipeline, turn on the coolant circulation pump, and observe that the water flow at the top coolant outlet 9 is stable. Then, high-temperature medium is introduced through the coolant inlet 3. Set the target temperature in the temperature control module, and the temperature control module automatically adjusts the coolant flow rate. When the temperature of the coolant at the coolant outlet 9 stabilizes at the set value, sampling begins. Additionally, during shutdown maintenance, stop the coolant from entering, drain the pipeline, turn off the coolant circulation pump, remove the bolts of the mounting cover 6, and lift the entire pipeline out for cleaning. Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
