Description

Technical Field

[0001] The utility model belongs to the technical field of drinking water quality detection, and particularly relates to an integrated testing device for total dissolved solids. Background Art

[0002] Total dissolved solids refer to the total amount of all solutes in water, including the contents of both inorganic and organic substances. Among inorganic substances, in addition to the components dissolved in ionic form, there may also be inorganic substances in molecular form. Since the organic substances and inorganic substances in molecular form contained in natural water generally can be ignored, the salt content is generally also called total dissolved solids. Total dissolved solids is a key indicator for evaluating the mineralization degree of water quality. The total dissolved solids of water is the general term for the organic substances and inorganic salts dissolved in water, and the level of this indicator is closely related to people's production, life and physical health. For example, when the mineralization degree of water is relatively high, it is easy to accumulate scale, resulting in low heat exchange efficiency. At the same time, domestic water with a relatively high mineralization degree affects people's daily life.

[0003] The existing methods for detecting water quality require experimental personnel to dry the evaporating dish in the oven room, let it cool, and weigh it. Weigh and dry it repeatedly until it reaches a constant weight; filter the water sample in the laboratory, collect the filtered water sample and evaporate the water, then put the evaporating dish into the oven room to dry, let it cool, and weigh it. Weigh and dry it repeatedly until it reaches a constant weight. When the existing laboratory is planned, the oven, balance, and experimental bench are placed in different rooms, which requires experimental personnel to shuttle back and forth between different laboratories repeatedly, and they need to pay attention to the progress of the experiment at all times, resulting in low work efficiency.

[0004] In summary, the existing laboratory planning results in low efficiency in testing total dissolved solids. Content of the Utility Model

[0028] Embodiment of the integrated testing device for total dissolved solids:

[0029] As Figures 1-4As shown, an integrated test device for total dissolved solids includes a box body 1, a track 15, a slider 16 that cooperates with the track 15, a telescopic connecting member 9, and a main controller; one end of the connecting member 9 is connected to the slider 16, and the other end is used to connect to an evaporating dish. The track 15 is fixed above the interior of the box body 1. A transmission belt controlled by a transmission box 19 is provided inside the track 15. The above-mentioned slider 15 is fixedly connected to the transmission belt, and the main controller is controllably connected to the transmission box 19. The track 15 can be one or two parallel ones. Figure 1 The track 15 is not drawn in the figure. If one track 15 is adopted, the two sliders 16 run on the same track 15. If two parallel tracks 15 are adopted, each slider 16 corresponds to one track 15 respectively.

[0030] Inside the box body 1, a support plate, a heating plate 5, a cooling tabletop 6, and a weighing table 7 are sequentially arranged along the sliding direction of the slider 16; above the support plate, a filtering device for filtering dissolved solids is provided.

[0031] In order to isolate the heating area and the weighing area; a sealed heat-insulating plate 8 is slidably arranged inside the box body 1 perpendicular to the sliding direction of the slider 16. The sealed heat-insulating plate 8 is located between the heating plate 5 and the cooling tabletop 6. When the heating plate 5 needs to be heated, the sealed heat-insulating plate 8 is inserted to divide into two spaces; when the heating is completed, the sealed heat-insulating plate 8 is withdrawn, and the evaporating dish slides with the slider 16 to enter the cooling tabletop 6 for cooling, and then reaches the weighing table 7 for weighing. As Figure 3 shown, the track 15 is a circular guide rail structure, and a rail gap 17 is provided on the track 15 for the sealed heat-insulating plate 8 to pass through. Figure 3 The upper surface of the box body 1 and the humidity sensor 10 in the figure are not drawn.

[0032] To improve the convenience of operation, the main controller is controllably connected to the slider 16, the telescopic movement of the connecting member 9, the sealed heat-insulating plate 8, the heating plate 5, and the weighing table 7. The main controller is used to control the sliding of the slider 16, the telescopic movement of the connecting member 9, the pulling out and inserting of the sealed heat-insulating plate 8, the startup of the heating plate 5, and the startup of the weighing table 7.

[0033] To facilitate pouring the solution to be tested, the filtering device is a funnel 2. The upper edge of the funnel 2 is flush with the upper surface of the box body 1. It also includes a support frame 4 provided on the inner wall of the box body 1. The support frame 4 is used to support the above-mentioned funnel 2. Let the support frame 4 provide a supporting effect for the funnel 2. Such a structure facilitates replacing the funnel 2 at any time.

[0034] In order to simplify the structure of the connecting component 9 as much as possible, the upper surfaces of the support plate, the heating plate 5, the cooling table 6 and the weighing table 7 are located on the same horizontal plane. In this way, when the connecting component 9 is extended or retracted, as long as a certain length can be extended or retracted, the evaporating dish can be lifted and separated from the surface of the corresponding table and plate, and the evaporating dish can be lowered and placed on the surface of the corresponding table and plate. If the heights of the various tables are inconsistent, the connecting component 9 needs to complete multiple extension lengths, which places higher requirements on the connecting component 9.

[0035] like Figure 1 , Figure 2 As shown, the connecting component 9 includes a vertical rod, a movable rod and a fixed ring. One end of the vertical rod is hinged to the slider 16, and the other end is connected to one end of the movable rod through a universal joint. The other end of the movable rod is hinged to the fixed ring, and the fixed ring is used to support the evaporating dish. The main controller is connected to the driver control of the universal joint to control the universal joint to drive the movable rod to move closer to or away from the vertical rod in the vertical plane. When the evaporating dish needs to be raised, the main controller controls the universal joint driver to drive the universal joint to rotate, and the universal joint drives the movable part to move closer to the vertical part, so as to achieve the effect of raising the fixed ring. The fixed ring drives the evaporating dish upward, and the effect of controlling the evaporating dish is achieved by controlling the universal joint driver. Of course, the connecting component 9 can adopt any structure that can realize the telescopic function to achieve the lifting and lowering of the evaporating dish.

[0036] In order to facilitate the pulling and drawing operation of the sealing insulation board 8, a slide groove is provided on the bottom surface of the box body 1, and a partition opening 18 is provided on the front of the box body 1. The sealing insulation board 8 passes through the partition opening 18 and cooperates with the slide groove to realize the division of the space of the box body 1. As another embodiment, the partition opening 18 can also be provided at the back of the box body 1. If the slide groove is provided at the front and / or back of the box body 1, the corresponding partition opening 18 can also be provided on the top of the box body 1.

[0037] In order to realize automatic control, a temperature sensor 11 for detecting temperature is arranged above the cooling table 6, and the temperature sensor 11 is connected to the master controller signal. That is, the master controller can judge the temperature of the solution in the current evaporating dish being cooled according to the signal of the temperature sensor 11.

[0038] A humidity sensor 10 for detecting humidity is arranged above the heating plate 5, and the humidity sensor 10 is connected to the master controller signal. That is, the master controller can judge the degree of heating of the solution in the current evaporating dish according to the signal of the humidity sensor 10.

[0039] In order to keep the box body 1 dry, the test device further includes a silica gel 12 with color change, which is arranged inside the box body 1 and below the cooling table surface 6, and is used for moisture absorption and drying. Since there is more liquid at this place compared with other positions of the box body 1, setting the silica gel 12 with color change here can better complete the work of drying the box body 1. An air vent 14 is provided on the box body 1 directly opposite the heating plate 5.

[0040] In order to facilitate the staff to observe the situation inside the box body 1, the test device further includes a display screen 13 that is data-transmission connected to the main controller, and the display screen 13 is arranged on the side surface outside the box body 1.

[0041] When the integrated test device for total dissolved solids is in use, first pour the water sample to be tested into the funnel 2, and the evaporating dish placed on the support plate collects the filtered water sample. After the filtration is completed, the main controller controls the slider 16 to drive the evaporating dish to the heating plate 5 for heating. When heating, the air vent 14 can timely discharge the water vapor from the box body 1. The main controller controls the heating plate 5 to stop heating according to the data of the humidity sensor 10, and controls the sealed heat-insulating plate 8 to be withdrawn. The slider 16 drives the evaporating dish to move to the cooling table surface 6, and the sealed heat-insulating plate 8 is inserted. According to the signal of the temperature sensor 11, after the temperature returns to room temperature, the main controller controls the slider 16 to drive the evaporating dish to slide to the weighing platform 7 for weighing. After the weighing is completed, the data is transmitted to the main controller, and the display screen 13 displays the first mass of the weighing. Then it is moved to the heating plate 5 again for heating and evaporation, and the above steps are repeated until the change amount of the mass weighed by the weighing platform 7 is less than the set mass threshold, and the set mass threshold is equal to 0.4 mg.

[0042] The above is only a preferred embodiment of the present invention, and does not impose any limitation on the present invention. Any simple modification, change and equivalent structural change made to the above embodiment according to the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
