Description

Technical Field

[0001] This utility model relates to the field of alkaline solution density determination, and in particular to a constant temperature water bath device for alkaline solution density determination. Background Technology

[0002] The determination of the density of alkaline solution needs to be performed at a constant temperature of (20±0.1)℃: Place the test sample into a clean, dry graduated cylinder (250mL), ensuring there are no air bubbles, and place the graduated cylinder in a constant temperature water bath at (20±0.1)℃. After the temperature stabilizes, slowly place the clean, dry hydrometer into the sample, ensuring that its lower end is at least 2 cm away from the bottom of the graduated cylinder and does not contact the cylinder wall. The liquid covering the upper part of the hydrometer protruding above the liquid surface should not exceed (2-3) graduations. After the hydrometer stabilizes in the liquid, read the scale line at the lower edge of the meniscus of the hydrometer, which is the density of the sample at 20℃.

[0003] However, the current temperature for measuring the density of alkaline solution is difficult to meet the requirements. The constant temperature water bath used is a traditional water bath heating pot, which has poor temperature stability and an accuracy of 0.1℃. In actual operation, it is difficult to meet the standard requirements by measuring with a thermometer. In addition, the water level of the water bath pot is low, which makes it difficult to heat the alkaline solution in the upper part of the measuring cylinder and to fully control the temperature. Large water bath pots occupy a large area and are difficult to set up and use in the limited space of the laboratory. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing laboratory water bath heating pots, such as uneven heating of alkaline solutions and large floor space requirements, and to provide a constant temperature water bath device for determining the density of alkaline solutions.

[0005] This utility model provides a constant temperature water bath device for determining the density of alkaline solution, comprising:

[0006] A water bath container is provided with a water bath space, an inlet pipe and an outlet pipe. The inlet pipe and the outlet pipe are respectively connected to the water bath space. A medium container is provided in the water bath space. The medium container is connected to the water bath container. The side wall of the water bath space is spaced apart from the water bath space. The medium container is provided with a medium space and a medium filling port. The medium filling port is connected to the medium space.

[0007] A constant temperature water circulation device is provided, which is connected to the inlet pipe and the outlet pipe; a density meter is provided in the medium space, and the density meter is detachably connected to the medium container.

[0008] This invention relates to a constant-temperature water bath device for determining the density of alkali solution. The constant-temperature water circulation device circulates water within the water bath space through inlet and outlet pipes, maintaining the temperature within the water bath space at a suitable level to ensure a constant heating temperature for the alkali solution. Alkali solution can be added to the medium space through the medium addition port. The sidewalls of the medium container and the water bath space are spaced apart, ensuring that the constant-temperature water contacts the sidewalls of the medium container, guaranteeing uniform heating of the medium container and thus the alkali solution. The constant-temperature water circulation device and the water bath container are connected through the inlet and outlet pipes, reducing the floor space required. A densitometer can measure the density of the alkali solution within the medium space. In use, alkali solution is added to the medium space through the medium addition port, and the constant-temperature water circulation device is activated to introduce constant-temperature water into the water bath space. The constant-temperature water circulation device maintains a constant water temperature within the water bath space, continuously heating the alkali solution to the specified temperature before the density of the alkali solution is measured using a densitometer.

[0009] Preferably, the water bath container is provided with an inlet and an outlet. The inlet is connected to the top side of the water bath space, and the outlet is connected to the bottom side of the water bath space. The inlet is connected to the inlet pipe, and the outlet is connected to the outlet pipe.

[0010] The inlet and outlet are connected to the top and bottom sides of the water bath space, respectively. When the constant temperature water circulation device circulates the constant temperature water, it allows the constant temperature water to flow fully in the water bath space, thereby making the constant temperature water heat the medium container more evenly.

[0011] Preferably, both the water bath container and the medium container are transparent structural components.

[0012] Operators can observe the alkaline solution level in the medium space through the transparent structural components, thereby accurately controlling the amount of alkaline solution injected into the medium space.

[0013] Preferably, the medium container is provided with scale lines.

[0014] By setting scale lines, the amount of alkali injected can be observed intuitively, making it easier for operators to adjust the amount of alkali injected.

[0015] Preferably, the water bath container has an opening at the top, the medium addition port is located at the top of the medium container, the opening communicates with the medium addition port, and the bottom of the medium container is connected to the water bath container.

[0016] The opening connects the water bath space to the outside, facilitating a rapid rise in the liquid level within the water bath and making it easier to add alkali solution under the influence of gravity.

[0017] Preferably, the water bath container is connected to the medium addition port, and the water bath space is a sealed chamber.

[0018] By connecting the water bath container to the medium addition port, the water bath space forms a sealed chamber, thereby improving the heat preservation effect of the water bath space and ensuring the constant temperature effect of the medium container; and preventing the alkaline solution in the medium container from entering the water bath space.

[0019] Preferably, the medium container is provided with a support, the support is detachably connected to the densitometer, and the support is clamped to the medium addition port.

[0020] The measuring part of the densitometer is suspended in the medium space by using a bracket to ensure the measurement accuracy of the densitometer.

[0021] Preferably, the water bath container and the medium container are integrally formed structural components.

[0022] This improves the connection strength between the water bath container and the medium container.

[0023] Preferably, the constant temperature water circulation device includes a constant temperature water tank, the constant temperature water tank is provided with an inlet and an outlet, the inlet is connected to the outlet pipe, and the outlet is connected to the inlet pipe.

[0024] A constant temperature water bath can heat flowing water to keep the water temperature constant. Through the inlet and outlet, the water flows at a constant speed in the constant temperature water bath, thus keeping the water temperature in the water bath space constant.

[0025] Preferably, the constant temperature water bath is equipped with a temperature control structure, and the temperature control structure is connected to a control panel.

[0026] The temperature control structure heats the water in the constant temperature water bath and maintains the water in the constant temperature water bath at a specified temperature. The control panel can control the heating temperature of the constant temperature water bath by the temperature control structure, so that the water in the constant temperature water bath can maintain a constant temperature.

[0027] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0028] 1. This utility model discloses a constant temperature water bath device for determining the density of alkali solution.

Alkali solution can be added to the medium space through the medium addition port. The side wall of the medium container is spaced apart from the side wall of the water bath space, ensuring that the constant temperature water contacts the side wall of the medium container, guaranteeing uniform heating of the medium container and thus uniform heating of the alkali solution. The constant temperature water circulation device and the water bath container are connected through the inlet and outlet pipes, reducing the floor space occupied. The densitometer can measure the density of the alkali solution in the medium space. In use, alkali solution is added to the medium space through the medium addition port, and the constant temperature water circulation device is activated to introduce constant temperature water into the water bath space. The constant temperature water circulation device maintains a constant water temperature in the water bath space, continuously heating the alkali solution in the medium space to a specified temperature, after which the density of the alkali solution is measured using a densitometer.

[0029] 2. This utility model provides a constant temperature water bath device for determining the density of alkali solution. By constructing an external circulation system through a constant temperature water bath, an inlet pipe, an outlet pipe, and a water bath space, the footprint is reduced, and the constant temperature water bath continuously keeps the medium container warm, achieving precise temperature control of the alkali solution in the medium space.

A water bath space 51 is provided inside the water bath container 5. An inlet pipe 2 and an outlet pipe 3 are provided on the outer wall of the water bath container 5, respectively connecting the inlet pipe 2 and the outlet pipe 3 to the water bath space 51, allowing water to flow within the water bath space 51. A medium container 6 is provided inside the water bath space 51, and the medium container 6 is connected and fixed to the water bath container 5. The side walls of the water bath container 5 and the water bath space 51 are spaced apart, allowing water to circulate within the space. The water bath container 5 can be heated evenly. The medium container 6 is provided with a medium space 61 and a medium inlet 62. The medium inlet 62 is connected to the medium space 61, so that the alkaline solution is put into the medium space 61 from the medium inlet 62. The constant temperature water circulation device 1 is connected to the water inlet pipe 2 and the water outlet pipe 3, so that the constant temperature water circulation device 1 can continuously inject constant temperature water into the water bath space 51. A densitometer 4 is provided in the medium space 61. The densitometer 4 is detachably connected to the medium container 6 and the density of the alkaline solution is measured by the densitometer 4.

[0047] The constant temperature water circulation device 1 circulates the water in the water bath space 51 through the inlet pipe 2 and the outlet pipe 3, maintaining the temperature in the water bath space 51 at a suitable temperature to ensure a constant heating temperature of the alkali solution. It can add alkali solution into the medium space 61 through the medium addition port 62. The side wall of the medium container 6 is spaced apart from the side wall of the water bath space 51, ensuring that the constant temperature water contacts the side wall of the medium container 6, guaranteeing uniform heating of the medium container 6, and thus uniform heating of the alkali solution. The constant temperature water circulation device 1 and the water bath container 5 are connected through the inlet pipe 2 and the outlet pipe 3, reducing the floor space occupied. The density meter 4 can measure the density of the alkali solution in the medium space 61. In use, the alkali solution is added into the medium space 61 through the medium addition port 62, and the constant temperature water circulation device 1 is activated to flow constant temperature water into the water bath space 51. The constant temperature water circulation device 1 maintains a constant water temperature in the water bath space 51, continuously heating the alkali solution in the medium space 61 to the specified temperature, and then the density of the alkali solution is measured using the density meter 4.

[0048] Specifically, the volume of the medium space 61 is at least 250 milliliters.

Specifically, a through hole is provided in the middle of the support 8, and a spring member 81 is provided on the support 8 to abut against the densitometer 4. After the densitometer 4 is inserted into the through hole, it is abutted against the outer wall of the densitometer 4 by the spring member 81, thereby limiting the densitometer 4. An abutting member 82 is provided at the bottom of the support 8, which abuts against the inner wall of the medium container 6, thereby limiting the support 8.

[0055] In one or more embodiments, the water bath container 5 and the medium container 6 are integrally formed structural components; specifically, the water bath container 5 and the medium container 6 are integrally formed double-layer measuring cylinders.
