Description

Technical Field

[0001] The invention relates to the technical field of thermostats, and in particular to an intelligent thermostat for measuring Henry's constant of methane in water. Background Art

[0002] The content of dissolved methane in water is one of the important indicators for water environment and resource surveys. Currently, laboratories usually use the theoretical Henry's constant of methane in water to measure this indicator. However, the Henry's constant of methane in different types of water is not the same. In order to pursue higher-precision measurements, it is necessary to first determine the Henry's constant of methane.

[0003] At present, the method for determining the Henry constant of methane mostly uses the spike / headspace equilibrium method. It places multiple gas-liquid equilibrium liquid preparation devices in a constant temperature device, and then uses the controlled variable method to measure the Henry constant of methane in the experimental raw liquid water at 25°C.

[0004] However, the commonly used thermostats can only hold four gas-liquid balance dispensing devices. The number of slots in this device is fixed, and it cannot be used in experiments that require more than four gas-liquid balance dispensing devices to be placed at the same time. Therefore, a multi-station thermostat was developed, but the overall size of this device is large, the space occupied is large, and each chamber conducts heat separately, which makes the temperature control uneven and the temperature rise is relatively slow. Summary of the invention

[0005] The purpose of the present invention is to provide an intelligent constant temperature device for measuring Henry's constant of methane in water, so as to solve the technical problems in the prior art that the device is large in size and each placement chamber conducts heat independently, resulting in uneven temperature rise.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] like Figures 1 to 3 As shown, the present invention provides a multi-station constant temperature device for measuring the Henry constant of methane in water, including a plurality of insulation chambers 1 which are sequentially arranged, and a channel gate 2 which can be opened and closed is arranged on the bottom plate of the insulation chamber 1, and the channel gate 2 is used to carry a gas-liquid balance device and to lower the gas-liquid balance device.

[0035] Two adjacent insulation cavities 1 are slidably connected via a linkage assembly 3, and the linkage assembly 3 can fix the position of the insulation cavity 1 after sliding. Multiple insulation cavities 1 are vertically slid and fixed in sequence to form a longitudinally arranged tower structure to accommodate multiple insulation cavities 1 at the same time.

[0036] An independent heating structure 4 is provided on each heat-insulating cavity 1 . As the heat-insulating cavity 1 slides upward, each heating structure 4 is connected in series with the heating structure 4 on the adjacent heat-insulating cavity 1 to form a reflux passage to heat the multiple heat-insulating cavities 1 synchronously.

[0037] In this device, the characteristics of multiple insulation cavities 1 that are interconnected and can be stretched longitudinally are utilized to solve the problem in the prior art that multiple insulation cavities 1 are horizontally laid out on a plane, resulting in a large footprint, and the multiple insulation cavities 1 after expansion are connected in series through the heating structure 4, so that the multiple insulation cavities 1 can be heated synchronously, so that the heating speed is consistent and the temperature remains balanced.

[0038] Specifically, the channel gate 2 is provided on the one hand to support the insulation cavity 1, on which a stable placement groove may be provided, or a snap-on assembly for fixing the gas-liquid balance device may be further provided to stably fix the gas-liquid balance device inside the insulation cavity 1.

[0039] On the other hand, when the channel gate 2 is opened, it is used to lower the gas-liquid balance device into the next layer of the insulation cavity 1. For example, when multiple gas-liquid balance devices need to be placed in the insulation cavity 1, all the upper channel gates 2 can be opened first, and the gas-liquid balance device can be placed in the bottom insulation cavity 1, and then the upper insulation cavity 1 can be slid up. After the rising position is fixed, the next channel gate 2 is closed, and then the gas-liquid balance device is loaded on this channel gate 2, and then unfolded and placed in sequence, so that multiple gas-liquid balance devices can be placed in the independent insulation cavity 1 in sequence.

[0040] Of course, the gas-liquid balance device can also be placed in sequence when multiple insulation cavities 1 are unfolded into a tower structure. The channel gates 2 of all the insulation cavities 1 unfolded into a tower structure are opened, and the gas-liquid balance device is placed in sequence from bottom to top, and the channel gates 2 are closed in sequence, thereby completing the placement of the gas-liquid balance device.

[0041] Among them, when the channel gate 2 is selected in the prior art, it needs to have at least the following conditions.

[0042] It has a certain length and width to facilitate the placement of the gas-liquid balance device;

[0043] Its opening and closing is automatically opened, such as external remote control, electric drive, pneumatic and the like.

[0044] It has good sealing when closed to prevent the heat transfer liquid from leaking.

[0045] For example, it can be set to be telescopic, with a groove set on one side of the channel gate 2 and an insert embedded in the groove set on the other side. The insert is pushed into the groove by the telescopic rod to complete the closing of the channel at the gate.

[0046] The linkage assembly 3 is used to connect two adjacent heat preservation chambers 1 and enable them to slide relative to each other, and can be fixed after sliding to a specified position, and can withstand the gravity effect of the gas-liquid balance device and the heat transfer liquid after being fixed.

[0047] like Figure 2 and Figure 3As shown, the linkage component 3 can use a sliding structure configured in the prior art, such as a ball slide rail, or a simple structural design, such as a connection between a slide groove and a slider arranged on the side wall of the insulation cavity 1. However, when selecting the linkage component 3, it is preferred to set the side walls of the two insulation cavities 1 to fit. Adjacent insulation cavities 1 are slidably connected in a side wall fitting manner. On the one hand, the fitting setting makes it possible for there to be no gap between the two insulation cavities 1, so that after the subsequent heat transfer liquid is introduced, it is difficult for the liquid molecules generated by the heating to enter between the two insulation cavities 1, thereby avoiding corrosion damage to the linkage component 3 or the bridge piece 42. On the other hand, the fitting setting can also shorten the distance between the liquid inlet 51 and the liquid outlet 52 of the adjacent insulation cavities 1, so that the conduction of the heat transfer liquid is tighter.

[0048] The heating structure 4 includes a heating plate 41 and a bridge plate 42 . The heating plate 41 is arranged inside the side wall of the heat preservation cavity 1 , and the bridge plate 42 is arranged outside the side wall of the heat preservation cavity 1 . The bridge plate 42 is connected to the heating plate 41 .

[0049] The bridge piece 42 includes an inner bridge piece 421 and an outer bridge piece 422. The inner bridge piece 421 is arranged on the upper part of the inner wall of the insulation cavity 1, and the outer bridge piece 422 is arranged on the lower part of the outer wall of the insulation cavity 1. The inner bridge piece 421 and the outer bridge piece 422 on adjacent insulation cavities 1 can be connected to form a current path after being fixed in the sliding position.

[0050] Furthermore, a heating plate 41 is arranged inside the side wall of the heat preservation cavity 1, and the heating plates 41 on two adjacent heat preservation cavities 1 are connected by a bridging plate 42 after sliding out, so as to form a series connection of multiple heating structures 4, thereby achieving synchronous heating.

[0051] The heating source can be connected to the heating plate 41 on the innermost heat preservation cavity 1. For example, it is connected to the power supply through a guide wire from the top of the side wall to introduce electric energy into the heating plate 41, thereby completing the heating function.

[0052] The bridge piece 42 is divided into an inner bridge piece and an outer bridge piece 422, and the heating structure 4 on the adjacent insulation cavity 1 is connected in series through the connection of the inner bridge piece 421 and the outer bridge piece 422. The position where the two are connected can be defined by the linkage component 3. That is, when the linkage component 3 raises the insulation cavity 1 to a fixed position, the inner bridge piece 421 and the outer bridge piece 422 on the two insulation cavities 1 are just in contact. In other words, the specific setting positions of the inner bridge piece 421 and the outer bridge piece 422 and the setting position where the two are connected can be defined by the fixed position after the linkage component 3 raises the insulation cavity 1. Through measurement and testing, after the specific position setting is completed, the inner bridge piece 421 is connected to the outer bridge piece 422 after the insulation cavity 1 is raised and fixed.

[0053] Further, such as Figure 2 and Figure 3 As shown, a bridging groove 6 is opened on the side wall of the heat preservation cavity 1, and the inner bridging piece 421 or the outer bridging piece 422 is arranged in the bridging groove 6, and the inner bridging pieces 421 and the outer bridging pieces 422 on adjacent heat preservation cavities 1 are connected in the bridging groove 6.

[0054] When two heat-insulating cavities 1 slide against each other, the bridge pieces 42 disposed on the side walls of the heat-insulating cavities 1 may be worn. Therefore, a bridge groove 6 is provided on the side wall of one heat-insulating cavity 1, and an inner bridge piece 421 or an outer bridge piece 422 is disposed in the bridge groove 6. Then, when the heat-insulating cavity 1 slides, the outer bridge piece 422 or the inner bridge piece 421 corresponding to it slides in the bridge groove 6, so that it will not be worn until it slides to the top end and contacts each other.

[0055] Figure 2 and Figure 3 It shows a schematic diagram of the side walls of two adjacent heat preservation chambers 1, wherein the inner bridge piece 421 and the outer bridge piece 422 are exposed in the arc-shaped area, and the two are arranged one above the other to be connected after the heat preservation chamber 1 slides and rises. Specifically, the bridge piece 42 and the trial and heating sheet 41 are in the same plane, and the guide channel 43 is set in front of the bridge piece 42. The guide channel 53 can be set as a larger square channel for guide. Since the bridge piece 42 needs to be connected, the guide channel 53 is set in the arc-shaped area to avoid the connection of the bridge piece 42.

[0056] Furthermore, a heat transfer liquid is arranged around the outside of the gas-liquid balance device in the heat preservation cavity 1 .

[0057] The heat transfer liquid enters into the multiple heat preservation cavities 1 synchronously through the flow guiding structure 5;

[0058] The guide structure 5 includes a liquid inlet 51, a liquid outlet 52 and a guide channel 53 arranged on the wall of the insulation cavity 1, wherein the liquid inlet 51 is arranged on the inner side of the wall of the insulation cavity 1 and is located above the liquid outlet 52, and the guide channel 53 is arranged inside the wall of the insulation cavity 1 and connects the liquid inlet 51 and the liquid outlet 52.

[0059] The liquid outlet 52 includes an external liquid outlet 521 and an internal liquid outlet 522. The internal liquid outlet 522 is arranged on the inner side of the wall of the insulation cavity 1 for supplying water to the insulation cavity 1, and the external liquid outlet 521 is arranged on the outer side of the wall of the insulation cavity 1. After the external liquid outlet 521 is slid and fixed on the insulation cavity 1, it is docked with the liquid inlet 51 on the adjacent insulation cavity 1 for guiding liquid downward, and the external liquid outlet 521 is docked with the liquid inlet 51 at the upper position of the bridging plate 42.

[0060] In this device, similar to the heating structure 4, the heat transfer liquid can be added into the heat preservation cavity 1 one by one, but this method is too troublesome and inconvenient to operate. Therefore, a flow guide structure 5 is provided to utilize the design of the channel and the gravity of the heat transfer liquid to synchronously inject the heat transfer liquid into multiple heat preservation cavities 1 from top to bottom, so that the overall synchronization is higher and the operation is more convenient.

[0061] Among them, the connection of the flow-guiding structures 5 of multiple insulation cavities 1 is achieved through the liquid inlet 51 and the liquid outlet 521 on the adjacent insulation cavity 1. When the insulation cavity 1 is raised to a fixed position, the liquid outlet 521 thereon is connected with the liquid inlet 51 of the insulation cavity 1 below, thereby completing the docking. Among them, the docking of the liquid outlet 521 and the liquid inlet 51 not only requires accurate alignment, but also requires a certain degree of sealing after the docking is completed to prevent the heat transfer liquid from overflowing during the diversion. Therefore, the specific design can be to set a sealing ring on the liquid inlet 51 and the liquid outlet 521, or to set a telescopic docking. During docking, the liquid outlet 521 is stretched and inserted into the liquid inlet 51 to complete the docking and sealing.

[0062] Furthermore, the guide channel 53 and the heating plate 41 are arranged in parallel inside the side wall of the heat preservation cavity 1 , the guide channel 53 is arranged on the side close to the outside of the heat preservation cavity 1 , and the heating plate 41 is arranged on the side close to the inside of the heat preservation cavity 1 .

[0063] like Figure 1 As shown, through this arrangement, the heating plate 41 can heat the heat transfer liquids on both sides at the same time, thereby achieving a better heating effect.

[0064] Specifically, the heating plate 41 is clamped between the heat transfer liquid inside the insulation cavity 1 and the heat transfer liquid in the guide channel 53, so that when the heating plate 41 is working, it heats these two parts of the heat transfer liquid at the same time, so that the heat transfer liquid has been heated by the heating plate 41 before it is guided into the insulation cavity 1 below. This advance heating method can make the temperature of the heat transfer liquid finally arranged outside the gas-liquid balance device more balanced and the overall heating faster.

[0065] In addition, the liquid inlet 51 and the inner liquid outlet 522 are connected to the guide channel 53 above and below the heating plate 41, respectively, so as to avoid conflicts between the liquid inlet and the liquid outlet and the setting position of the heating plate 41.

[0066] In addition, the inner liquid outlet 522 is arranged below the outer liquid outlet 521 to prevent the heat transfer liquid in the upper heat preservation cavity 1 from flowing down from the outer liquid outlet 521 when the heat transfer liquid in the lower heat preservation cavity 1 is not full. Therefore, the inner liquid outlet 522 is arranged below the outer liquid outlet 521.

[0067] Furthermore, the inner liquid outlet 522 and the outer liquid outlet 521 divide the heat transfer liquid in the flow guide channel 53, and the flow rates of the heat transfer liquid discharged through the inner liquid outlet 522 and the outer liquid outlet 521 are equal.

[0068] In addition, a cover body 7 is provided on the innermost heat preservation cavity 1 of the tower structure. The inner hole of the cover body 7 stores heat transfer liquid. The cover body 7 is provided with a guide hole 8 connected with the liquid inlet 51 .

[0069] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
