Description

Technical Field

[0001] This utility model relates to the technical field of water adding devices, and more specifically, to a water adding device. Background Technology

[0002] When determining the calorific value of coal in the laboratory, a specialized instrument (constant-temperature calorimeter) is required. The basic principle is as follows: the sample to be tested is placed inside an oxygen bomb, the lid is closed, and oxygen is introduced. The oxygen bomb is then placed into the inner chamber of the calorimeter to begin the test. A certain amount of water is injected into the inner chamber at this time. Once the conditions are met, electricity is applied to ignite the sample in the oxygen bomb. The released heat is absorbed by the water in the inner chamber, thus determining the calorific value of the sample. However, an important step in the measurement process is to inject 10 ml of distilled water into the oxygen bomb before placing the sample inside. This is to promote the interaction between the sample and the 10 ml of distilled water after combustion in the oxygen bomb, forming sulfuric acid heat and nitric acid heat. The formation of these two additional heats will be corrected in the later calculations.

[0003] In existing technologies, adding 10ml of water is usually done manually using a metering container or pipette. If there are too many samples to be tested, the process of adding water will be cumbersome, which will increase the labor intensity of the staff and reduce the efficiency of testing samples. Utility Model Content

[0004] This invention provides a water filling device to solve the problem of the cumbersome process of injecting water into an oxygen bomb in the prior art.

[0005] This utility model provides a water filling device, comprising: a support base having a receiving cavity and a water inlet connected to each other, a water filling part on the upper end face of the support base for placing an oxygen bomb, and a water inlet for connecting to an external water source; a water tank located inside the receiving cavity, having a water storage chamber, a water inlet, and a drain outlet, both of which are connected to the water storage chamber and the water inlet is connected to the water inlet; a frame located above the support base, having a water outlet corresponding to the water filling part, a connecting pipe between the water outlet and the drain outlet, one end of the connecting pipe being connected to the water outlet and the other end being connected to the drain outlet, and a water pump being installed on the connecting pipe; and a control structure electrically connected to the water pump to control the operation of the water pump.

[0006] Furthermore, a cleaning section is provided on the support base, and a cleaning port is provided on the frame. The cleaning port is provided in correspondence with the cleaning section. The cleaning section is used to place the oxygen bomb, and the cleaning port is used to connect to an external water source.

[0007] Furthermore, the frame is provided with a first sensing element and a second sensing element. The first sensing element is located near the water outlet and is used to sense the oxygen bomb in the water filling section. The second sensing element is located near the cleaning port and is used to sense the oxygen bomb in the cleaning section.

[0008] Furthermore, the water filling section includes a water filling groove for placing the oxygen bomb, and the cleaning section includes a cleaning groove for placing the oxygen bomb.

[0009] Furthermore, a first waterproof plate is provided on the water filling section, and a second waterproof plate is provided on the cleaning section.

[0010] Furthermore, there is a partition plate between the frame and the support base, with the water outlet, water inlet and first sensing element located on one side of the partition plate, and the cleaning port, cleaning part and second sensing element located on the other side of the partition plate.

[0011] Furthermore, there is a water supply pump between the water inlet and the external water source, and a cleaning pump between the cleaning outlet and the external water source.

The drain outlet and outlet of the water tank are connected by a connecting pipe, and a water pump is installed on the connecting pipe. An external water source is injected into the receiving cavity through the water inlet and outlet. The control structure is electrically connected to the water pump and precisely controls the running time of the water pump according to a preset program, thereby injecting a fixed amount of distilled water into the oxygen bomb. With this configuration, when the liquid level in the water tank decreases, the external water source is injected into the receiving cavity through the water inlet and outlet. This configuration ensures that the water pump flow rate will not change due to changes in water level, guaranteeing the accuracy of water injection into the oxygen bomb.

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0041] like Figure 1 and Figure 2 As shown, this embodiment of the utility model provides a water filling device, which includes a support base 10, a water tank 20, a frame 30, and a control structure 50. The support base 10 has a receiving cavity and a water inlet 11 that are interconnected. The upper end surface of the support base 10 has a water filling part 12, which is used to place an oxygen bomb. The water inlet 11 is used to connect to an external water source. The water tank 20 is located in the receiving cavity and has a water storage chamber, a water inlet 21, and a drain outlet 22. Both the water inlet 21 and the drain outlet 22 are connected to the water storage chamber, and the water inlet 21 is connected to the water inlet 11. The frame 30 is located above the support base 10 and has a water outlet 31. The water outlet 31 is correspondingly arranged with the water filling part 12. There is a connecting pipe between the water outlet 31 and the drain outlet 22. One end of the connecting pipe is connected to the water outlet 31, and the other end of the connecting pipe is connected to the drain outlet 22. A water pump 41 is installed on the connecting pipe. The control structure 50 is electrically connected to the water pump 41 to control the operation of the water pump 41.

[0042] Using the technical solution of this application, the oxygen bomb is placed on the water filling section 12. The drain outlet 22 and the outlet 31 of the water tank 20 are connected by a connecting pipe. A water filling pump 41 is installed on the connecting pipe. An external water source is injected into the receiving cavity through the water supply port 11 and the water filling port 21. The control structure 50 is electrically connected to the water filling pump 41. The control structure 50 precisely controls the running time of the water filling pump 41 according to a preset program, thereby injecting a fixed amount of distilled water into the oxygen bomb. With this configuration, when the liquid level in the water tank 20 decreases, the external water source is injected into the receiving cavity through the water supply port 11 and the water filling port 21. This configuration ensures that the flow rate of the water filling pump 41 will not change due to changes in the water level, thus guaranteeing the accuracy of water injection into the oxygen bomb. By setting up the water filling pump 41 and the control structure 50, the water filling process is automated, improving the automation level of the water filling device. It eliminates the need for manual operation by personnel, significantly improving the water injection efficiency and accuracy, reducing the difficulty of water injection, and thus improving the efficiency of test samples.

[0043] In existing technologies, some water-filling mechanisms operate on a principle similar to a syringe. The water-filling mechanism draws in the required amount of water and injects it into the oxygen bomb under pressure. However, the water-filling process cannot be completely separated from manual operation. In this application, the water pump 41 automatically fills the oxygen bomb with water, eliminating the need for manual operation by personnel and significantly improving water-filling efficiency.

[0044] The support base 10 is provided with a cleaning section 13, and the frame 30 is provided with a cleaning port 32. The cleaning port 32 is provided in correspondence with the cleaning section 13. The cleaning section 13 is used to place the oxygen bomb, and the cleaning port 32 is used to connect to an external water source.

[0045] Since the oxygen bomb needs to be reused during the testing process, it must be cleaned before reuse to remove the sulfuric acid and nitric acid heat inside, thus avoiding affecting subsequent test results. The cleaning port 32 on the frame 30 can clean the oxygen bomb, and the cleaned oxygen bomb can be immediately placed in the water filling section 12 for reuse. This design can shorten the time interval between cleaning and water filling, further improving the efficiency of testing samples.

[0046] Furthermore, since the oxygen bomb does not require metered water injection during the cleaning process, an external water source can be used, eliminating the need for water tank 20. This reduces the efficiency of injecting water into water tank 20 and simplifies the water filling process.

[0047] Specifically, the frame 30 is provided with a first sensing element 33 and a second sensing element 34. The first sensing element 33 is located near the water outlet 31 and is used to sense the oxygen bomb of the water filling section 12. The second sensing element 34 is located near the cleaning port 32 and is used to sense the oxygen bomb of the cleaning section 13.

[0048] With this configuration, the use of the first sensing element 33 and the second sensing element 34 enables the water supply device to automatically identify whether the oxygen bomb is placed in the water supply section 12 and the cleaning section 13, thereby automatically starting the corresponding water supply or cleaning program without manual intervention, thus improving the automation level of the entire testing process.

[0049] Furthermore, the sensing element can accurately determine the position of the oxygen bomb, ensuring that water addition or cleaning only begins when the oxygen bomb is correctly placed, thus avoiding failure to add water or clean due to improper placement and enhancing the accuracy and reliability of the operation.

[0050] Furthermore, in this application, both the first sensing element 33 and the second sensing element 34 are infrared sensing switches 23.

[0051] The water filling section 12 includes a water filling groove for placing an oxygen bomb, and the cleaning section 13 includes a cleaning groove for placing an oxygen bomb.

[0052] This design, with its water filling and cleaning recesses, ensures that the oxygen bomb has a fixed placement position during water filling and cleaning, guaranteeing accurate alignment of the oxygen bomb in each operation. Furthermore, the water filling and cleaning recesses can hold water dripping from the water outlet 31 and cleaning port 32, preventing water from contaminating the working environment.

[0053] Specifically, a first waterproof plate is provided on the water filling section 12, and a second waterproof plate is provided on the cleaning section 13.

[0054] With this configuration, water splashing or dripping may occur during water filling and cleaning operations in the water filling section 12 and the cleaning section 13. The first and second waterproof plates can prevent splashed or dripping water from penetrating into the support base 10, protecting the circuitry and structure inside the cavity from moisture, preventing short circuits or damage to the water filling device, and improving the stability and service life of the water filling device.

[0055] Furthermore, a partition plate 60 is provided between the frame 30 and the support base 10. The water outlet 31, the water filling part 12 and the first sensing element 33 are located on one side of the partition plate 60, and the cleaning port 32, the cleaning part 13 and the second sensing element 34 are located on the other side of the partition plate 60.

[0056] With this configuration, the partition 60 divides the device into two independent areas: one side is dedicated to adding water, and the other side is for cleaning. This layout makes the functional modules of the device clearer, allowing operators to intuitively distinguish between the water adding and cleaning areas, avoiding confusion and misoperation.

[0057] Furthermore, the partition plate 60 can prevent water splashed from one of the water supply section 12 and the cleaning section 13 from splashing onto the other.

[0058] The water inlet 11 is connected to an external water source by a water supply pump 42, and the cleaning inlet 32 ​​is connected to an external water source by a cleaning pump 43. The water supply pump 42 and the cleaning pump 43 are electrically connected to the control structure 50, and the control structure 50 can control the operation of the water supply pump 42 and the cleaning pump 43.

[0059] This configuration allows the water pump 42 to automatically replenish distilled water from an external water source, ensuring that the water tank 20 always has sufficient water to meet the needs of continuous testing. This function reduces the frequency of manual intervention, improves work efficiency, and avoids test interruptions due to water shortage in the water tank 20.

[0060] Furthermore, the introduction of the cleaning pump 43 enables automatic cleaning of the oxygen bomb. When the oxygen bomb is placed in the cleaning groove, the control structure 50 automatically starts the cleaning pump 43 to draw cleaning water from an external water source for efficient cleaning of the oxygen bomb. The automated cleaning process reduces the workload of personnel while improving the accuracy and thoroughness of cleaning, ensuring the reliability of the test.

[0061] Specifically, an induction switch 23 is installed in the water storage chamber to detect the liquid level in the water storage chamber. The induction switch 23 is electrically connected to the control structure 50. The induction switch 23 can transmit a signal to the control structure 50, and the control structure 50 can control the operation of the water replenishment pump 42 according to the signal from the induction switch 23.

[0062] With this configuration, the sensor switch 23 can monitor the liquid level in the water storage chamber in real time. Once it detects that the water level is lower than the preset minimum level, it immediately sends a signal to the control structure 50, which then starts the water replenishment pump 42 to replenish water until the water level reaches the set maximum level. This automatic control ensures that the water supply device always has a sufficient water supply during operation, avoiding test interruptions or equipment failures due to water shortage.

[0063] In this application, the inductive switch 23 is a float switch.

[0064] Furthermore, the top of the water tank 20 has an exhaust port 24, which is connected to the water storage chamber.

[0065] This design allows the vent 24 to help maintain pressure balance inside and outside the water tank 20, ensuring that water flows freely between the tank 20 and the pump without pressure obstruction. This makes the water replenishment and addition process more stable and continuous, improving water circulation efficiency. Furthermore, when the water level reaches its highest point, excess water can overflow through the vent 24.

[0066] Specifically, there is a support column 70 between the support base 10 and the frame 30. One end of the support column 70 is connected to the support base 10, and the other end of the support column 70 is connected to the frame 30.

[0067] With this configuration, the support column 70, as a key component connecting the support base 10 and the frame 30, can significantly enhance the structural stability of the entire water supply device.

[0068] In this application, the support base 10 is equipped with a power supply and a speed adjustment switch. The power supply controls the opening and closing of the entire water filling device, and the speed adjustment switch is electrically connected to the control structure 50. Adjusting the speed adjustment switch can adjust the water output of the outlet 31.

[0069] Furthermore, commercially available liquid dispensing devices are generally bulky and have large liquid capacities, lacking suitable automated equipment for small-volume liquid dispensing needs, thus limiting their application. However, the water dispensing device of this application is smaller in size and can inject 10ml of distilled water into the oxygen bomb, meeting the needs for small-volume liquid dispensing.
