Description

Technical Field

[0001] The utility model relates to a constant temperature device, in particular to a full-automatic multifunctional water bath device. Background Art

[0002] A water bath is a type of laboratory equipment capable of maintaining a constant operating temperature, widely used in the chemical, pharmaceutical, biological, and food industries. In environmental sample metal element monitoring, the metal element extraction and separation process typically requires initial water bath heating to promote efficient reaction, followed by cooling to expel gases from the solution. For samples containing acidic solutions, the water bath process requires the discharge of large amounts of corrosive acid gases. In batch environmental sample metal monitoring, to improve analytical accuracy and efficiency, higher requirements are placed on the water bath's automation, sample batch processing capacity, and corrosion resistance.

[0003] Water bath heating and cooling require a dual-function water bath. Existing water baths use heaters for heating and compressors for cooling. While effective, these systems are expensive to manufacture, bulky, and lack acid venting. Furthermore, commercially available water baths utilize spring-loaded mesh slots to stabilize sample containers. Moving one container often causes others to tilt, leading to sample leakage. This results in unstable sample containers and poor corrosion resistance, making them unsuitable for widespread laboratory use.

[0004] Chinese patent CN212732248U discloses a water bath tank that uses an electric heater and a cooler to achieve constant temperature. The water bath tank includes a tank body, a water bath chamber, a hot water chamber, a cold water chamber and a recovery chamber. The water bath chamber is connected to the recovery chamber through a pipeline. A recovery valve for controlling the communication state between the water bath chamber and the recovery chamber is provided in the tank body, and a recovery flow pump for driving the water in the water bath chamber to flow to the recovery chamber is provided; an electric heating mechanism and an electric cooling mechanism are provided in the tank body, the water bath chamber is connected to the hot water chamber and the cold water chamber at the same time through a pipeline, a hot water valve for controlling the communication state between the water bath chamber and the hot water chamber is provided in the tank body, a hot water flow pump for driving the water in the hot water chamber to flow to the water bath chamber, a cold water valve for controlling the communication state between the water bath chamber and the cold water chamber, and a cold water flow pump for driving the water in the cold water chamber to flow to the water bath chamber.

[0005] Chinese patent CN203971978U discloses a constant temperature water bath device for heating and cooling a compressor, which includes a base and a cylinder body. The cylinder body is arranged on the base, a compressor is arranged inside the base, and a circulation pipe is provided on the compressor. The circulation pipe passes through the base and enters the cylinder body, coils inside the cylinder body and then returns to the compressor; a controller is provided on the base, and the controller is electrically connected to the compressor; a temperature sensor is provided in the cylinder body, and the temperature sensor is electrically connected to the controller.

[0006] However, both of the above devices focus on quickly reaching or better maintaining the preset temperature, which increases the complexity and manufacturing cost of the equipment. They are also bulky and cannot be placed in a fume hood for operation, resulting in poor versatility. Utility Model Content

[0033] A fully automatic multifunctional water bath device, see Figure 1 and Figure 2 ;

Each hole is used to place a sample tube. The sample rack has two aperture sizes to accommodate different types of sample tubes; twenty-four retaining springs are provided at the bottom of the sample rack for fixing the corresponding sample tubes, and the material of each retaining spring is 304 stainless steel; twenty-four sealing covers 3 are provided on the inner surface of the upper flip cover 4, and the lower end of each sealing cover 3 is used to seal with the upper end of the corresponding sample tube, and the upper end of each sealing cover 3 is sealed with a sealing cover. Each end is connected to a corresponding suction pump 1 through an air suction pipe 2 provided through the upper flip cover 4; each sealing cover 3 is provided with a ventilation hole connected to the atmospheric environment to avoid negative pressure in the water bath 51 during the experiment, and the material of each sealing cover 3 is PTFE; the side of the upper flip cover 4 is connected to the top side of the water bath 5 by a hinge; the water bath 51 has a water outlet and a water inlet, the water outlet is connected to one end of the water outlet pipe 8, and the water inlet is connected to one end of the water inlet pipe 6, the water inlet pipe 6 is provided with a water inlet check valve 71, and the water outlet pipe 8 is provided with a water outlet check valve 72; a liquid level sensor 11 and at least one temperature probe 10 are provided in the water bath 5;

[0037] A circulation pump 12 circulates the water in the water bath 5 to ensure a uniform temperature. Two temperature probes 10 monitor the water temperature, and a liquid level sensor 11 monitors the water level.

[0038] A specific working process of the above-mentioned fully automatic multifunctional water bath device (sequential water bath heating and water cooling working process) is as follows:

[0039] Step 1: The operator first places the sample to be tested into the corresponding sample tubes, places the sample tubes into the sample rack, then opens the upper flip cover 4, places the sample rack containing the sample tubes into the water bath 5, and then closes the upper flip cover 4;

[0040] Step 2: The operator sets the water bath operating parameters on the touch screen 13 and turns on the fully automatic multifunctional water bath device after completion; at this time, the water inlet pump starts to supply water, and the water inlet check valve 71 located on the water inlet pipe 6 automatically opens, and water flows into the water bath 5 through the water inlet.

During the hot water bath, when the water level in the water bath 5 is lower than the preset position of the liquid level sensor 11 due to evaporation loss, the water inlet check valve 71 is opened and the system automatically replenishes water. During the hot water bath, each suction pump 1 is turned on at the same time to discharge the gas generated by the reaction in each sample tube during the hot water bath in a timely manner.

[0042] Step 4: After the hot water bath is completed, the water outlet one-way valve 72 on the water outlet pipe 8 is opened, and the system automatically discharges the hot water. After the drainage is completed, the water outlet one-way valve 72 is closed, and the water inlet one-way valve 71 is opened, and the system automatically supplies cold water. When the water level reaches the preset position of the liquid level sensor 11, after waiting for the preset heat exchange time, the water in the water bath 5 is emptied again and water is added to start the cold water bath.

[0043] Step 5: After the cold water bath is completed, the outlet pump is turned on, the outlet one-way valve 72 located on the outlet pipe 8 is opened, the system automatically drains, and the sequential water bath heating and water cooling process is completed.

[0044] This embodiment has the functions of water bath heating, water cooling and exhaust, has a high degree of automation, can improve the experimental accuracy, has a safe and reasonable structural design, can process a large number of samples in batches, has the ability to resist acid corrosion, and is highly practical.
