Description

Technical Field

[0001] The utility model belongs to the field of experimental equipment, relates to a water bath, and particularly relates to a water vapor compensation type water bath applicable to high altitude areas, which can compensate for the change of water vapor pressure, maintain the stability of experimental conditions, and is used for chemical analysis in environmental monitoring. Background Art

[0002] As a commonly used laboratory equipment, the water bath is widely used in the fields of chemical analysis, biological experiments, etc., providing a stable temperature environment for experiments. Traditional water baths usually work under standard atmospheric pressure (101.3 kPa) and achieve constant temperature control by heating water. Such equipment can meet the temperature requirements of most experiments in low altitude areas.

[0003] Although traditional water baths perform well in low altitude areas, they face a series of challenges in high altitude areas. As the altitude increases, the atmospheric pressure decreases significantly, resulting in a decrease in the boiling point of water. This not only affects the heating efficiency of the water bath but also affects the chemical reaction kinetics during the experiment, including the reaction rate and equilibrium state. Specifically, the main problems include:

[0004] a) Due to the decrease in the boiling point, it is difficult for the water bath to maintain a constant experimental temperature, resulting in fluctuations in experimental conditions.

[0005] b) The change in air pressure directly affects the rate and equilibrium of chemical reactions, affecting the accuracy of experimental results.

[0006] c) The existing water bath designs do not consider the specific requirements of high altitude areas and lack the ability to adapt to changes in air pressure.

[0007] In the prior art, for example, in the patent "CN103357455A - Constant Temperature High Pressure Water Bath", a design of a constant temperature high pressure water bath is proposed. This design uses a pressure limiting valve to increase the air pressure and water temperature in the pot to adapt to experimental conditions exceeding atmospheric pressure and 100 °C. However, this design is mainly for the detection of the true density of powder solids and is not suitable for chemical analysis and determination work in environmental monitoring, especially lacking in adaptability to changes in air pressure in high altitude areas.

[0008] With the continuous progress of science and technology and the improvement of experimental requirements, the performance requirements for water baths are also increasing. Especially in the field of environmental monitoring, a water bath that can provide stable experimental conditions at different altitudes is needed. In addition, with the increasing requirements for the accuracy and reliability of experimental data, developing a new type of water bath to meet the experimental needs of high altitude areas has become an inevitable trend in the industry.

[0052] The following is described in conjunction with the accompanying drawings and a specific embodiment.

[0053] To make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the scope of protection of the present utility model. Therefore, the following detailed description of the embodiments of the present utility model provided in the accompanying drawings is not intended to limit the scope of the present utility model to be protected, but merely represents the selected embodiments of the present utility model.

[0054] It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it may not be further defined and explained in subsequent drawings.

[0055] See Figures 1 to 4 This water-vapor compensation type water bath described in this embodiment includes the following structures.

[0056] Inner tank unit, that is, inner tank 110, which is the working space of the water bath and is designed to accommodate experimental containers. Inner tank 110 is made of high-temperature resistant and corrosion-resistant materials, such as stainless steel, to ensure its stability and durability under different experimental conditions. The volume of inner tank 110 is usually 2-3L.

[0057] Sealing cover 111 is designed to closely cooperate with inner tank 110 to form a sealed space, prevent external gases and pollutants from entering, and at the same time maintain the preset air pressure inside inner tank 110. Sealing cover 111 is detachably connected to inner tank 110. For example, internal threads 112 are provided along the mouth of inner tank, external threads are provided on sealing cover 111, and sealing cover 111 is threadedly connected to inner tank 110. Of course, a sealing ring can be provided at the connection to ensure the sealing effect.

[0058] Sensor group 150 is installed inside inner tank 110 and includes a temperature sensor, a water level sensor and a pressure sensor, which are used to monitor and collect the environmental parameter data inside inner tank 110 in real time.

[0059] Switch group 160 is installed on water bath 100 and responds according to the data collected by sensor group 150, including a temperature control switch, a water level control switch and a pressure control switch, which are used to adjust the working state of the water bath.

[0060] The water bath 100 in this embodiment further includes a central control unit (not shown in the figure) for integrally controlling the sensor group 150 and the switch group 160.

[0061] During use, place the experimental container in the inner tank unit 110, ensure that the sealing cover 111 is correctly installed on the inner tank 110 to form a sealed space. Start the water bath 100, and the central control unit will initialize and perform self-check. The sensor group 150 starts to monitor the environmental parameters inside the inner tank 110 and transmits the data to the central control unit. The operator sets the preset parameters such as the required temperature, water level, and air pressure according to the experimental requirements. According to the data collected by the sensor group 150, the switch group 160 automatically adjusts the heater, water pump, and air pressure control device to maintain the preset environmental parameters. After the experiment is completed, the operator turns off the water bath 100 and drains the water in the inner tank 110 through the drainage pipe. Clean the inner tank 110 and the sealing cover 111, and check the working status of the sensor group 150 and the switch group 160 to ensure the reliability of the equipment for the next use.

[0062] According to an embodiment of the water-vapor compensation type water bath of the present utility model, the inner tank 110 or the sealing cover 111 includes one or more pressure relief devices. The pressure relief device includes a pressure relief pipe 113, and a safety valve 114 is installed on the pressure relief pipe 113. The pressure relief pipe 113 extends from the inner tank 110 or the sealing cover 111 and is directly communicated with the inside of the inner tank 110. The design of the pressure relief pipe 113 ensures that it can serve as a pressure release channel when the pressure inside the inner tank 110 rises. The safety valve 114 is installed at the end of the pressure relief pipe 113, and its function is to automatically open when the pressure inside the inner tank 110 reaches the preset safety threshold to release the excessive pressure. The design of the safety valve 114 must meet strict safety standards to prevent misoperation when the safety threshold is not reached. Preferably, the preset value of the pressure inside the inner tank 110 is 1 standard atmospheric pressure.

[0063] The water-vapor compensation type water bath described in this embodiment realizes precise control of experimental conditions through its automated control system and precise environmental monitoring capabilities. The design of the pressure relief device ensures safety in use, and the design of the air intake and drainage systems improves the convenience of operation. Overall, the water bath 100 of the present invention provides an efficient, safe, and user-friendly experimental environment control solution.

[0064] According to an embodiment of the water-vapor compensation type water bath of the present utility model, the water bath 100 further includes an air intake pipe 120, and the air intake pipe 120 connects the air supply pipeline and the inner tank 110; a one-way valve 121 is installed at the pipe orifice of the air intake pipe 120. The one-way valve 121 is installed at the pipe orifice of the air intake pipe 120, and its function is to allow air to flow unidirectionally from the air supply pipeline into the inner tank 110, and at the same time prevent water or steam from flowing back from the inner tank 110 into the air supply pipeline.Figure 3 and Figure 4 shows a situation where the nozzle of the intake pipe 120 is located at the bottom of the inner tank 110, and the one-way valve 121 is also located at the bottom of the inner tank 110. The clean air flows unidirectionally from the air supply pipeline into the inner tank 110, and the impurities it may contain can be absorbed by the water in the inner tank 110. When the central control unit receives the air pressure sensor signal from the sensor group 150 indicating that the inner tank 110 needs to be replenished with air, the intake system starts to work. The air supply pipeline supplies clean air to the intake pipe 120. As the air flows in, the air pressure in the inner tank 110 gradually rises to a preset value. The air pressure sensor continuously monitors the air pressure in the inner tank 110 and feeds it back to the central control unit to achieve precise air pressure control. When performing chemical analysis at high altitudes, the external air pressure is relatively low, and the intake system of the water bath 100 can provide additional air pressure support to the inner tank 110 to maintain a constant air pressure environment required for the experiment. For example, when measuring the permanganate index, the intake system can ensure the stability of the air pressure and temperature in the inner tank 110, thus guaranteeing the accuracy of the experimental results.

[0065] According to an embodiment of the water and gas compensation type water bath of the present utility model, the water bath 100 further includes a water inlet pipe 130, and the water inlet pipe 130 connects the water supply pipeline and the inner tank 110. The water inlet pipe 130 is made of a durable and corrosion-resistant material to ensure stability under different water quality and temperature conditions. The pipeline is designed with an appropriate diameter to meet the water flow rate required by the inner tank 110. One end of the water inlet pipe 130 is connected to the external water supply pipeline through a quick connector or a threaded interface, and the other end is connected to the inner tank 110 through a sealed connection to ensure smooth water flow and prevent leakage. When the water bath 100 is started, the water level sensor in the sensor group 150 starts to work and continuously monitors the water level in the inner tank 110. When the water level is lower than the preset experimental requirements, the central control unit will send a signal. After receiving the signal from the central control unit, the water inlet pipe 130 starts to supply water, delivering water from the water supply pipeline to the inner tank 110 until the water level reaches the preset threshold. During the experiment, the water level sensor continuously monitors the change in the water level in the inner tank 110. Once the water level drops, the water inlet pipe 130 will be started again to maintain the required water level. The automatic water replenishment function of the water inlet pipe 130 reduces manual monitoring and intervention and improves the automation level of the experiment. After the experiment is over, the operator can close the water supply of the water inlet pipe 130 through the central control unit and start the drain pipe 140 to drain the water in the inner tank 110 to prepare for the next experiment or equipment cleaning.

[0066] According to an embodiment of the water-vapor compensation type water bath of the present utility model, it further includes a display 170. The display 170 is preferably a display screen with high contrast and high definition, which can display environmental parameters such as the temperature, water level, and air pressure inside the inner container 110 in real time. It is usually integrated on the control panel of the water bath 100, facilitating the operator to intuitively read the data. The display 170 may include, but is not limited to, a digital display screen, an LCD screen, or a touch screen interface. During the experiment, the operator can monitor the environmental state inside the inner container 110 through the display unit to ensure the stability of the experimental conditions. When the water bath 100 is started, the display 170 will be automatically activated to display the parameters in the initial state. The sensor group 150 collects environmental parameters such as the temperature, water level, and air pressure inside the inner container 110 and transmits the data to the display 170. The display 170 will update the readings of these parameters in real time. The operator can intuitively monitor the environmental state inside the inner container 110 during the experiment through the display 170. Any change in the parameters can be observed immediately, thus ensuring the stability of the experimental conditions. In some embodiments, when the sensor group 150 detects that the environmental parameters deviate from the preset values, the display 170 can display warning or prompt messages to guide the operator to make corresponding adjustments.
