Description

Technical Field

[0001] The utility model belongs to the technical field of fertilizers, and in particular relates to a fertilizer flatulence detection device. Background Art

[0002] If compound fertilizers, liquid fertilizers, microbial fertilizers, organic fertilizers and other products are not fully reacted or fermented and decomposed enough during the production process and are packaged and sold, barrel swelling, liquid overflow and other phenomena may occur during the subsequent transportation and storage of the products. At the same time, fungal fertilizers will inevitably produce a certain amount of gas due to the reproduction and respiration of live bacteria. If the fertilizer packaging container does not have enough space reserved for gas, barrel swelling, liquid overflow and other phenomena may also occur. In addition, if the organic fertilizer is not fully decomposed enough, it will further decompose and produce heat and ammonia after being applied to the soil, thereby causing seedling burn. The maturity of the organic fertilizer can be judged based on the degree of flatulence.

[0003] As can be seen from the above, during the development of fertilizer products, it is essential to test and confirm whether the product will cause bloating and the extent of bloating. Currently, the conventional method for testing bloating in this field is to place a certain mass of fertilizer sample in a mineral water bottle, press it to the minimum volume, screw on the cap, and observe whether the mineral water bottle deforms after a period of time and the degree of deformation recovery. This serves as the basis for determining whether the fertilizer product will cause bloating and the extent of bloating.

[0004] Meanwhile, to determine the degree of flatulence in organic fertilizer, patent application number 201910097851.5 discloses a wide-mouth bottle for testing the moisture content, bulk density, or maturity of organic fertilizer. This testing instrument for organic fertilizer features a cylindrical wide-mouth bottle with a body and mouth of equal diameter, and two raised rings on the wall below the mouth. When using this wide-mouth bottle to test maturity, the degree of bulging of the sealing film is directly used to determine whether the organic fertilizer is decomposed. This method is simple to use and provides reliable and accurate results.

[0005] The two aforementioned detection methods are mainly based on the naked eye judgment of R&D personnel. It is difficult to form quantitative detection records during the product development process. There are large deviations in the judgment of whether the finished product reaction is complete or the degree of maturity. In addition, the judgment of the degree of flatulence is also difficult to use to guide the design of the reserved gas space in the packaging container. Summary of the Invention

[0058] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0059] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0060] like Figures 1 to 6As shown, a fertilizer flatulence detection device includes a fertilizer container 5, which is placed on a machine base 6. The machine base 6 is provided with a heating device A, a controller 10, a temperature sensor 11 and a human-computer interaction device, and the human-computer interaction device is a control button 7 and a display screen 8.

[0061] The heating device A, the temperature sensor 11 and the human-computer interaction device are electrically connected to the controller 10 .

[0062] The fertilizer container 5 includes a body 502 and a cover 501. The heating device A and the body 502 form heat conduction directly or indirectly, thereby heating or keeping warm the fertilizer sample loaded in the body 502, thereby accelerating the fermentation process or simulating the highest possible ambient temperature.

[0063] The cover 501 is provided with an air outlet opening 501 a penetrating into the inner space of the body 502 . The air outlet opening 501 a is connected to the quantitative air bag 1 or the pressure gauge 4 or to both the quantitative air bag 1 and the pressure gauge 4 .

[0064] The quantitative air bag 1 includes N (4) unit air bags (N>1), each of which has the same volume (1L), and multiple unit air bags are connected in sequence. The unit air bag at the head end is set as the first unit air bag 103, and the unit air bag at the tail end is set as the Nth unit air bag. The first unit air bag 103 is provided with an air inlet interface, and the air inlet interface can be detachably connected to the air outlet cover 501a.

[0065] There are communicating air holes between the plurality of unit air bags connected in sequence. The air holes are provided with elastic self-closing membrane flaps 101. The elastic self-closing membrane flaps 101 are opened or closed toward the tail end.

[0066] The fertilizer in the fertilizer container 5 generates gas after being heated and fermented. The gas flows into the first unit air bag 103. As the fermentation time increases, the first unit air bag 103 is gradually filled with gas. The elastic self-closing membrane flap 101 between the first unit air bag 103 and the second unit air bag is opened by top pressure, and the gas begins to enter the second unit air bag. And so on, until the flatulence detection is completed and the gas fills M unit air bags (M≥1).

[0067] First, compared to existing technologies, by recording the number M of filled unit air bags, the degree of flatulence in a fertilizer sample can be simply and quickly quantified. Second, given that the gas generated by each fertilizer sample during the R&D process is valuable for research and testing, the design of the quantification air bag 1 also allows for gas storage to support other testing experiments. Finally, the design of the quantification air bag 1 ensures that the flatulence determinations obtained through testing in this embodiment can effectively guide the amount of gas space reserved in fertilizer packaging containers. In practical applications, if the Mth unit air bag is filled with gas but not full, it can simply be recorded as 0.5.

[0068] If a very precise value is required, the air outlet cover 501a may be connected to the pressure gauge 4 for reading.

[0069] Based on the above, it can be seen that the gas generated by the fertilizer sample has research value. Therefore, in this embodiment, each unit air bag is provided with an extraction hole 102 for inserting an extraction device, so that R&D personnel can perform multiple and quantitative extractions for other R&D experiments.

[0070] In practical applications, the quantified airbag 1 is typically made of rubber, and the finished product is shaped like a long, bendable strip of beads strung together. However, a curved quantified airbag 1 may be squeezed, causing the elastic self-closing membrane flap 101 to accidentally open. Therefore, a shaped connection 105 is provided between the unit airbags, and the bending of the quantified airbag 1 is restricted by the shaped connection 105. It should be noted that the hardness of the shaped connection 105 only needs to prevent the quantified airbag 1 from bending more than 30° relative to its length; it is not necessary to achieve a completely straight and rigid effect.

[0071] The quantitative air bag 1 that has collected gas should try to make the flow direction of the internal gas (i.e., upward) opposite to the direction of the elastic self-closing membrane flap 101. At the same time, it can be seen from the above that this embodiment should not be bent for storage after collecting gas. Therefore, in this embodiment, only the first unit air bag 103 is provided with a hanging mouthpiece 106 to remind and restrict R&D personnel to only hang and store this embodiment in a single direction, that is, to place this embodiment in a hanging manner with the first unit air bag 103 located above.

[0072] In this embodiment, the air outlet cover 501a is connected to and communicates with a Y-shaped pipe fitting, and the Y-shaped pipe fitting has a first branch and a second branch.

[0073] The first branch is provided with a first solenoid valve 2 and is detachably connected to the quantified air bag 1. The first solenoid valve 2 is electrically connected to the controller 10. The air inlet interface of the first unit air bag 103 is a one-way valve port 104 (specifically a rubber duckbill valve). The one-way valve port 104 is detachably connected to and communicates with the tail end of the first branch.

[0074] The second branch is provided with a second solenoid valve 3 and connected to the pressure gauge 4 (U-shaped mercury pressure vacuum gauge). The second solenoid valve 3 is electrically connected to the controller 10. Researchers can choose to open or close the first branch or the second branch according to actual needs, which is convenient and flexible to use.

[0075] In this embodiment, the body 502 has a spherical bottle body and a bottle mouth. The width of the spherical bottle body is greater than the bottle mouth and the width of the bottle body gradually narrows toward the bottle mouth, guiding the gas generated by the fertilizer to flow toward the gas outlet cover 501a. At the same time, the larger bottle body can avoid the magnetic stirring block B1 described below from colliding with the bottle wall as much as possible.

[0076] Taking into account that if the fertilizer sample being tested is severely flatulent, the cover 501 may be pushed open and thus affect the test, the bottle mouth of the spherical bottle body and the cover 501 should be connected in a manner that is not easily pushed open and is easy to open. Specifically in this embodiment, a matching threaded connection structure is provided between the bottle mouth of the spherical bottle body and the cover 501.

[0077] In this embodiment, the heating device A includes a heat-conducting bowl A1 and an electric heating ring A2. The electric heating ring A2 is mounted on the outer side of the bottom of the heat-conducting bowl A1. The electric heating ring A2 is electrically connected to the controller 10. The temperature sensor 11 contacts the heat-conducting bowl A1.

[0078] The control buttons 7 include a temperature control button 7. The user selects a target temperature via the temperature control button 7 and the display screen 8, and transmits this to the controller 10. The controller 10 then controls the electric heating coil A2 to initiate heating until the temperature sensor 11 detects that the heat-conducting bowl A1 has reached the target temperature. This temperature is also maintained constant through this feedback path. Since the heating device A of this embodiment is only used to simulate a fermentation temperature or storage environment temperature for the fertilizer sample, it is not necessary to accurately detect the temperature of the fertilizer sample in the fertilizer container 5; it is sufficient to simply control the heat-conducting bowl A1 to the target temperature.

[0079] The inner surface of the heat-conducting bowl A1 is exposed to the top surface of the base 6. The fertilizer container 5 is placed in the heat-conducting bowl A1. The shape of the heat-conducting bowl A1 increases the thermal contact surface. The spherical bottle body is half-enclosed by the heat-conducting bowl A1. The notch of the heat-conducting bowl A1 does not exceed the widest point of the spherical bottle body, making it easy to place and remove.

[0080] Specifically, at least the bottom of the spherical bottle forms surface contact with the heat-conducting bowl A1, ensuring a large contact area and improving heat transfer efficiency. The bottom of the spherical bottle is made of metal with good thermal conductivity, while the rest of the body is made of high-temperature-resistant transparent glass, making it easier for researchers to observe changes in the appearance of fertilizer samples.

[0081] This embodiment further includes a stirring device B, which has the following functions: first, it can accelerate the fermentation process; second, it can simulate the vibration during transportation to observe whether there is flatulence change in the fertilizer under this situation.

[0082] The stirring device B includes a motor B3, a two-pole rotating member B2 and a magnetic stirring block B1.

[0083] The bipolar rotating member B2 is equipped with two oppositely mounted magnetic blocks with opposite magnetic poles. The output end of the motor B3 is directly or indirectly connected between the two magnetic blocks, driving the bipolar rotating member B2 to rotate. The bipolar rotating member B2 is mounted below the heat-conducting bowl A1 but does not contact it. The magnetic stirring block B1 is placed in the fertilizer container 5. The magnetic poles at both ends of the magnetic stirring block B1 are oppositely oriented. Driven by the rotating bipolar rotating member B2, the magnetic stirring block B1 moves within the fertilizer container 5 to stir the fertilizer sample. The reasons for using magnetic stirring are: first, it allows the fertilizer container 5 to be completely separated from the base 6 for cleaning; second, compared with conventional stirring blades, the regular shape of the magnetic stirring block B1 is easier to clean.

[0084] Specifically, the base 6 is provided with a heat dissipation hole 601 below the motor B3, and the bottom of the base 6 is provided with a plurality of legs to allow the bottom to be suspended in the air.

[0085] In order to ensure the accuracy of the conclusion on the degree of flatulence, the mass of the sample for each flatulence test on the same fertilizer sample is the same. Therefore, this embodiment also includes a weighing component C installed in the machine base 6. After the fertilizer container 5 is placed and peeled, the sample mass can be weighed.

[0086] The weighing assembly C includes a mounting stand C1 and at least two weighing sensors C2 (three weighing sensors C2 are provided in this embodiment, Kunwei Technology, product model KWT1D15).

[0087] The upper part of the mounting stand C1 is a cylindrical structure C101, and the lower part is a plurality of pillars C102. The inner diameter of the cylindrical structure C101 is larger than the maximum width of the electric heating coil A2. The cylindrical structure C101 supports the bottom of the heat-conducting bowl groove A1.

[0088] The inner side of the cylindrical structure C101 is provided with a plurality of (3) mounting grooves C103 that are evenly distributed around the circumference and located at the same horizontal height. The number of the mounting grooves C103 is the same as the number of the weighing sensors C2. The weighing sensors C2 are fixed in the mounting grooves C103. A contact column C3 is provided between the bottom of the heat-conducting bowl groove A1 and the sensing end of the weighing sensor C2. The weighing sensor C2 is electrically connected to the controller 10. The display screen 8 displays the mass value. The control button 7 includes a "tare" button.

[0089] Since the flatulence test duration generally exceeds 24 hours and multiple fertilizer samples may be tested simultaneously, errors are easily missed if the developer simply records the start time. Therefore, this embodiment further includes a timing module and a flashing indicator light 9. The timing module is integrated into the control panel, and the flashing indicator light 9 is electrically connected to the controller 10. The control button 7 includes a duration control button 7. The developer selects the test duration via the duration control button 7 and the display screen 8. After the set test duration, the controller 10 starts the flashing indicator light 9 to flash to notify the developer that the test has ended.

[0090] Based on the disclosure and teachings of the above specification, those skilled in the art may also make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should also fall within the scope of protection of the claims of the present invention. In addition, although some specific terms are used in this specification, these terms are only for convenience of description and do not constitute any limitation to the present invention.
