Description

Technical Field

[0001] The utility model relates to the technical field of soil detection, in particular to an automatic constant temperature water replenishing device for a constant temperature water bath oscillator. Background Art

[0002] Soil is an irreplaceable resource for human survival and development. With the development of heavy industry, heavy metal pollution in soil has become a serious problem faced by contemporary humans. Among them, hexavalent chromium pollution has become an indispensable part of contemporary soil monitoring due to its serious toxicity. Hexavalent chromium is a poison for ingestion and extremely toxic for inhalation. Skin contact may cause sensitivity and may even cause genetic defects; inhalation may cause cancer; and it has a lasting harm to the environment. From the source of hexavalent chromium pollution in soil, waste gas, wastewater, and waste residues discharged from the production and operation activities of industrial enterprises are the main causes of annual soil pollution; at the same time, the stacking of various solid wastes such as tailings, hazardous wastes, etc. will also cause pollution to the surrounding soil. Therefore, accurate detection of hexavalent chromium in soil plays a very important role in the control of industrial pollution sources.

[0003] When extracting hexavalent chromium from the soil, it is necessary to stir at a constant temperature of 90℃ to 95℃ for 1 hour. Ordinary heating and stirring devices are not suitable for the pre-treatment needs of large-scale key enterprises for detailed inspection of samples. Therefore, constant temperature water bath oscillators are often used in the prior art for pre-treatment of soil to meet the pre-treatment needs of batch samples. During the use of the constant temperature water bath oscillator, the water temperature in the water tank needs to be maintained at 90℃ to 95℃. During this period, the evaporation of water will cause the water level in the water tank to drop. The samples cannot be completely below the water bath liquid level. The drop in the liquid level requires the operator to manually add water. This process requires the staff to manually boil water for a long time and observe the changes in the water level in the water bath at any time. The work process is cumbersome and takes a lot of time. In addition, the oscillation needs to be paused and the protective cover needs to be opened when adding water, which will cause the temperature of the water bath to drop. Utility Model Content

[0024] Specifically, a supporting foot is provided at the bottom of the base 1, a constant temperature water bath 10 is provided above the base 1, and a drain outlet is provided at the lower right side of the constant temperature water bath 10, and a valve is provided on the drain outlet. A water bath 11 is formed inside the constant temperature water bath 10, and other structures such as a control unit and an oscillation tray can also be provided on the constant temperature water bath 10. When in use, turn on the power to add an appropriate amount of water into the constant temperature water bath 10, put the soil to be treated into the relevant equipment on the oscillation tray, cover the transparent sealing cover, open the control unit, set the program through the programming panel as needed, and after the program is set, press the start button, and the constant temperature water bath 10 starts to work. This is the prior art of the constant temperature water bath oscillator and will not be repeated.

[0025] In this embodiment, a water replenishment tank 2 is further provided on the base 1, and the water replenishment tank 2 is provided on one side of the constant temperature water bath 10. A heating chamber is provided in the water replenishment tank 2, and a heating mechanism 20 capable of heating is provided inside the water replenishment tank 2. The water in the heating chamber can be heated by the heating mechanism 20. The water replenishment tank 2 is connected to the water bath 11 through a water replenishment pipe 21. The position of the water replenishment pipe 21 is higher than the highest liquid level of the water bath in the constant temperature water bath 10. A control valve 22 is provided in the water replenishment pipe 21. The control valve 22 can open or close the water replenishment pipe 21. In this way, when the liquid level in the constant temperature water bath 10 is lower than a preset value, the control valve 22 opens the water replenishment pipe 21, thereby replenishing the hot water in the water replenishment tank 2 to the water bath 11. When the water in the constant temperature water bath 10 reaches a preset water level, the control valve 22 closes the water replenishment pipe 21.

[0026] A first water level detection member 3 and a second water level detection member 4 are provided in the water bath 11. Both the first water level detection member 3 and the second water level detection member 4 can detect the water level in the water bath 11. The position of the first water level detection member 3 is higher than that of the second water level detection member 4. A control mechanism can also be provided on the constant temperature water bath oscillator. The first water level detection member 3, the second water level detection member 4 and the control valve 22 are all connected to the control mechanism. In actual use, the control mechanism can control the control valve 22 according to the detection results of the first water level detection member 3 and the second water level detection member 4, so that the water supply pipe 21 is opened or closed. The control unit and the control valve 22 can also be controlled according to the control mechanism. The control is performed at a preset time, such as the first water level detection member 3 is the highest water level of the water bath 11, and the second water level detection member 4 is the lowest water level of the water bath 11. First, the time for the water level in the water bath 11 to drop from the highest water level to the lowest water level is T1, and during the water replenishment process of the water replenishment pipe 21, the time for the water level in the water bath 11 to increase from the lowest water level to the highest water level is T2. In this way, at every interval of T1, the control mechanism controls the control valve 22 to open, and the water replenishment pipe 21 replenishes the hot water in the water replenishment tank 2 to the water bath 11. After replenishing for T2 time, the control valve 22 is closed, and after another interval of T1 time, the control mechanism continues to control the control valve 22 to open, and so on.

[0027] The utility model provides an automatic constant temperature water replenishing device for a constant temperature water bath oscillator, comprising a base 1, a water replenishing tank 2 and a constant temperature water bath 10 arranged above the base 1, a water bath 11 is formed inside the constant temperature water bath 10, the water replenishing tank 2 is arranged above the base 1 and located on one side of the constant temperature water bath 10, the water replenishing tank 2 is connected to the water bath 11 through a water replenishing pipe 21, a control valve 22 is arranged on the water replenishing pipe 21, a first water level detection member 3 at a higher position and a second water level detection member 4 at a lower position are arranged in the water bath 11, In this way, the water level in the water bath 11 can be detected or predicted by the first water level detection component 3 and the second water level detection component 4. When the liquid level in the water bath 11 is lower than the minimum water level, the water replenishment tank 2 and the water replenishment pipe 21 automatically replenish the water bath 11. When the liquid level in the water bath 11 reaches the maximum water level, the water replenishment tank 2 and the water replenishment pipe 21 automatically stop replenishing water, so that the water level in the water bath 11 is maintained at a relatively stable liquid level during the entire water bath process, thereby improving the treatment effect of the hexavalent chromium extraction in the soil.

[0028] In actual use, preferably, the control unit controls the control valve 22 through the detection results of the first water level detection member 3 and the second water level detection member 4, so that the water supply pipe 21 is opened or closed, that is, when the second water level detection member 4 detects that the water level in the water bath 11 is lower than the lowest water level, the control mechanism opens the control valve 22, and the water supply pipe 21 supplies the hot water in the water supply tank 2 to the water bath 11. When the first water level detection member 3 detects that the water level in the water bath 11 reaches the highest water level, the control mechanism closes the control valve 22. And because the water in the water bath 11 is shaking and splashing, the first water level detection member 3 and the second water level detection member 4 are directly set on the side wall of the water bath 11, which may cause inaccuracy in detection. Therefore, in another embodiment of the present invention, the first water level detecting member 3 includes a first detecting hole 30 arranged on the side wall of the water bath 11, and a first detecting member 31 is arranged inside the first detecting hole 30. The second water level detecting member 4 includes a second detecting hole 40 arranged on the side wall of the water bath 11, and a second detecting member 41 is arranged inside the second detecting hole 40. The effect of such a setting is that when there is always water in the first detecting hole 30, the first detecting member 31 detects and sends the detection information to the control mechanism, which indicates that the water level in the water bath 11 has reached the maximum water level. When there is no water in the first detecting hole 30, it indicates that the water level in the water bath 11 is lower than the maximum water level. Similarly, when there is always water in the second detecting hole 40, the second detecting member 41 detects and sends the detection information to the control mechanism, which indicates that the water level in the water bath 11 is higher than the minimum water level. When there is no water in the second detecting hole 40, it indicates that the water level in the water bath 11 is lower than the minimum water level.

[0029] In another embodiment provided by the utility model, preferably, a vertical hole 32 is provided at the top of the first detection hole 30 away from the water bath 11, and the first detection component 31 is located in the vertical hole 32, so that the first detection component 31 can detect water only when the first detection hole 30 is full of water, which can reduce the impact of water shaking, and the second detection hole 40 is an inclined hole structure, and the second detection hole 40 is at a higher position away from one end of the water bath 11, and the second detection component 41 is located at the higher end of the second detection hole 40, so that when the water level in the water bath 11 is lower than the lowest water level, the water will leave the second detection hole 40 and flow out, avoiding water residue in the second detection hole 40 and affecting the detection of the second detection component 41, and at the same time, since the second detection component 41 is located at the highest position of the second detection hole 40, the impact of water shaking can also be reduced.

[0030] In another embodiment provided by the utility model, preferably, it also includes a water replenishment component 5, which is arranged on the side wall of the water bath 11 and is connected to the water replenishment pipe 21. The water replenishment component 5 includes an annular water replenishment member 50 arranged in sequence along the circumference of the side wall of the water bath 11, and a water replenishment channel is arranged inside the annular water replenishment member 50. The water replenishment channel is connected to the water replenishment pipe 21, and the annular water replenishment member 50 is circumferentially provided with a plurality of vertical water replenishment structures 51, which are fitted and fixed on the side wall of the water bath 11; in this way, the water replenishment pipe 21, the water replenishment channel and the plurality of vertical water replenishment structures 51 are connected in sequence, and the water in the water replenishment pipe 21 will be transported to the water bath 11 along the inner wall of the water bath 11 through the water replenishment channel and the plurality of vertical water replenishment structures 51, so as to reduce the impact of the water replenishment pressure on the water surface in the water bath 11, and reduce the large fluctuation of the liquid level in the water bath 11 caused by water replenishment.

[0031] In another embodiment provided by the utility model, preferably, the vertical water replenishment structure 51 includes a vertical pipe 52 and a water replenishment part 53 arranged on the water replenishment pipe 21, and there are at least two water replenishment parts 53.

[0032] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
