Description

Technical Field

[0001] The utility model relates to a liquid adding device, in particular to a portable intelligent quantitative liquid adding box. Background Art

[0002] In environmental monitoring, water quality testing requires the collection of parallel water samples. The percentage of parallel samples collected and measured should be determined based on the batch size of the sample, the difficulty of the measurement, and whether there is quality control, etc., and is generally not less than 10% of all samples. Parallel samples, also known as parallel double samples, refer to samples that only include two identical sub-samples in environmental monitoring and sample analysis. Collecting and measuring parallel samples is a measure to implement quality assurance for environmental monitoring. The measurement results of parallel samples reflect the precision level of the test to a certain extent.

[0003] After collection, some fixatives need to be added to the samples for preservation. In daily work, the amount of fixative added is often inconsistent due to human operation, instrument errors and other reasons, resulting in inconsistent amounts of solution used to adjust the water quality detection properties during laboratory measurements, causing measurement errors for parallel samples.

[0004] Usually, the fixatives added to routine testing items in water sample collection can be classified as pH adjusters, bio-inhibitors, and redox agents. Through the intelligent control system of the liquid adder, quantitative liquid addition is performed for specific items, simplifying and standardizing the water sample handling procedures for on-site sampling personnel.

[0005] In summary, existing water quality testing has problems such as strong reliance on manual labor, large errors, large equipment size and complicated operation. Utility Model Content

[0006] The technical problem to be solved by the utility model is: to provide a portable intelligent quantitative liquid adding box in order to solve the problems of strong manual dependence, large error, large equipment volume and complicated operation in the existing water quality detection.

[0007] The technical solution adopted by the utility model to solve the technical problem is: a portable intelligent quantitative liquid adding box, including a box body, the top of the box body is provided with a box cover that can be flipped open and closed, the inner side of the box cover is provided with a touch screen, a horizontal partition and N vertical partitions are provided inside the box body, the bottom four corners of the horizontal partition are provided with legs, the horizontal partition is horizontally placed inside the box body, and the box body is divided into two layers, the lower space below the horizontal partition is provided with a power supply component and a controller, a vertical partition is provided above the horizontal partition, and the vertical partition divides the upper space above the horizontal partition into a plurality of installation positions, and a volumetric bottle and a metering pump are provided in the installation position, and the metering pump is connected to the volumetric bottle through a pipeline;

[0008] The controller is electrically connected to the touch screen, the power supply component and the metering pump respectively.

[0009] In order to provide an early warning to the operator, an infrared scanning module may be provided in the installation position. The infrared scanning module is installed adjacent to the volumetric flask and issues an early warning when the liquid level is lower than the setting value. The infrared scanning module is electrically connected to the controller.

[0010] In order to prevent the reagent from tipping over and spilling during transportation, a buckle for fixing the volumetric flask is provided in the installation position.

[0011] In order to realize intelligent control, the controller includes a charging and discharging module, a timing module, a statistical module, a control module, a storage module and a processing module.

[0012] In order to control the amount of liquid added as needed and avoid cross contamination when changing reagents, the metering pump is a split peristaltic pump with adjustable speed.

[0013] The beneficial effect of the utility model is that the portable intelligent quantitative liquid adding box of the utility model miniaturizes the existing large equipment and integrates it into a suitcase, which is smaller in size and can be carried to the site by one person. Each metering pump is controlled separately, and the operation is fool-proof. The metering pump uses a split peristaltic pump with small size and accurate metering. The split peristaltic pump has another advantage that when changing reagents, since the pipeline and the pump are separated, replacing the pipeline can prevent cross contamination of the reagents, and there is no need to clean the pump body.

[0014] In summary, the utility model has the characteristics of small size, light weight, easy to carry, high intelligence, high precision, low dependence on manual labor and small error. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Now the utility model is further described in detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0020] like Figure 1 and Figure 2A portable intelligent quantitative liquid adding box is shown, comprising a box body, which is preferably a suitcase with a handle on the top, and a flip-openable box cover 1 on the top of the box body, a touch screen 2 is installed on the inner side of the box cover 1, and a handle is installed on the outer side of the box cover 1.

[0021] A horizontal partition 3 and N vertical partitions 4 are installed inside the box. There are five vertical partitions 4 in the figure. The four corners of the bottom of the horizontal partition 3 have support legs 5. The horizontal partition 3 is horizontally placed inside the box to divide the box into two layers, and the power supply components and the controller are installed in the lower space 7 below the horizontal partition 3. Vertical partitions 4 are installed above the horizontal partition 3 at intervals. The installation method can be magnetic attraction, gluing, clamping or angle iron installation. The vertical partition 4 divides the upper space above the horizontal partition 3 into multiple installation positions 6. There are six installation positions 6 in the figure. A volumetric flask and a metering pump are installed in each installation position 6. The metering pump is connected to the volumetric flask through a pipeline; sulfuric acid, nitric acid, phosphoric acid, fixative 1, fixative 2 and fixative 3 are placed in the six installation positions 6 respectively.

[0022] The specification of the volumetric flask is 200ml, the diameter is 5cm, and the height is 10cm. In order to prevent the reagent from tipping over and overflowing during transportation, a buckle for fixing the volumetric flask is installed in the installation position 6, and the buckle is installed with the help of the horizontal partition 3 and / or the vertical partition 4; in order to provide an early warning to the operator, an infrared scanning module is also installed in the installation position 6. The infrared scanning module is installed adjacent to the volumetric flask. When the liquid level in the volumetric flask is lower than the setting, the infrared scanning module issues an early warning to remind the operator to replenish the liquid or replace the reagent.

[0023] The metering pump is preferably a split peristaltic pump with adjustable speed. The structure of the split peristaltic pump is as follows: Figure 2 As shown, the peristaltic pump itself has a metering function. When the split type is selected, the hose 8 can be directly replaced when the reagent is replaced. There is no need to clean the pump body, which can effectively prevent cross contamination of the reagents and ensure the accuracy of the experiment.

[0024] The circuit control is powered by a power supply component, which is centrally managed and controlled by a controller. The power supply component uses a lithium battery pack as the energy storage part and a battery management chipset as the protection part to ensure electricity safety. The power supply component supplies power to the controller, touch screen, metering pump and infrared scanning module.

[0025] The controller includes charging and discharging modules, timing modules, statistical modules, control modules, storage modules and processing modules. The number of modules can be increased or decreased according to the actual use environment. Each module corresponds to one or more functions, including:

[0026] The charge and discharge module controls the current and voltage of the lithium battery pack during charging and discharging, and works together with the cell management chip to further improve electricity safety.

[0027] The timing module is used in conjunction with the metering pump. It usually has countdown and hysteresis timing. After the countdown is set, the metering pump will automatically stop working when the time is up. When multiple metering pumps work together, a hysteresis timing is set, that is, the second pump starts after the first metering pump has worked for a certain period of time.

[0028] The statistics module counts the speed and running time of the metering pump, and calculates and counts the flow rate through the pipe diameter.

[0029] Storage module, saves the running data.

[0030] The processing module coordinates and optimizes the processing sequence, providing the best operating logic basis for the entire equipment, preventing multiple conflicting instructions from being issued at the same time. It can also start all metering pumps with one button, avoiding delays caused by manual operations one by one.

[0031] The control module automatically and intelligently controls the start and stop of the metering pump, the early warning of the infrared scanning module, the activation of the timing module, the activation of the statistics module, the activation of the storage module and the monitoring of the charging and discharging module according to the manual operation of the touch screen and after being processed by the processing module.

[0032] Since the power supply components, controller and control circuits of the power consumption unit belong to conventional control circuits, the drawings are omitted.

[0033] The above description only describes the specific implementation methods of the utility model. Various examples do not limit the essential content of the utility model. Ordinary technicians in the relevant technical field can modify or deform the specific implementation methods described above after reading the description without departing from the essence and scope of the utility model.
