Description

Technical Field

[0001] This application relates to the technical field of water-soluble bag dissolution testing equipment, and in particular to a pesticide water-soluble bag dissolution testing instrument. Background Technology

[0002] Water-soluble bags provide consumers with a single dosage of pesticide, conveniently packaged in a small bag, thus reducing the need for hand contact with users, improving the safety of pesticide application, and reducing environmental pollution from waste pesticide packaging. The application of water-soluble bags in pesticide packaging has a very broad prospect for promotion.

[0003] During the processing of water-soluble bags, their solubility needs to be tested. At the same time, the water solution with qualified solubility is used to test the suspension rate of the packaged pesticide products to determine the impact of using water-soluble packaging on the suspension rate of pesticide products, and thus determine whether the pesticide products packaged in water-soluble bags are qualified.

[0004] Regarding the aforementioned technologies, the inventors discovered that temperature is a crucial indicator affecting the dissolution rate of water-soluble bags during the dissolution test. However, the temperature during the dissolution test cannot be controlled, making it difficult to maintain a consistent temperature, which in turn affects the accuracy of the water-soluble bag dissolution test. Utility Model Content

[0005] To overcome the limitations of existing water-soluble bag dissolution tests, which cannot control the temperature during dissolution testing and thus compromise the accuracy of the test, this application provides a pesticide water-soluble bag dissolution tester.

[0006] The pesticide water-soluble bag dissolution tester provided in this application adopts the following technical solution: A pesticide water-soluble bag dissolution tester includes a dissolution component and a sealing component. The dissolution component includes a dissolution cylinder and an oil shell. The top surface of the dissolution cylinder is open, and a discharge pipe is vertically connected and fixed on the bottom surface of the dissolution cylinder. A valve is installed on the discharge pipe. The oil shell is fixedly fitted around the outside of the dissolution cylinder, and heat-conducting oil is added inside the oil shell. Multiple heating rods are evenly and vertically fixed inside the oil shell, and a temperature control switch is fixed on the top surface of the oil shell. The temperature control switch is connected in series with the power supply lines of the multiple heating rods, and the power supply terminal of the temperature control switch is electrically connected to the power supply lines. The sealing component includes a sealing cap, which can be lifted and inserted into the top opening of the dissolution cylinder.

[0007] By adopting the above technical solution, when conducting dissolution tests on pesticide water-soluble bags, the pesticide water-soluble bag is placed inside the dissolution cylinder. To facilitate temperature control within the cylinder, a heating rod inside the oil tank is activated via a temperature control switch to heat the oil inside. Once the oil is heated to a fixed temperature, it contacts the outer wall of the dissolution cylinder, providing constant-temperature heating for the pesticide water-soluble bag. By controlling the temperature during the pesticide water-soluble bag test, the accuracy of temperature control is ensured, maintaining a consistent temperature throughout the dissolution test and improving the precision of the water-soluble bag dissolution test.

[0008] Optionally, the outer wall of the oil tank is fitted with an insulation sleeve, and the insulation sleeve is fixed to the outer wall of the oil tank.

[0009] By adopting the above technical solution, in order to avoid heat loss in the oil tank and improve the heat utilization rate in the oil tank, the heat insulation sleeve is wrapped around the outer wall of the oil tank to reduce the heat loss in the oil tank through the outer wall of the oil tank.

[0010] Optionally, multiple supports are vertically fixed on the bottom surface of the dissolving cylinder, and brackets are vertically installed below the bottom surface of the multiple supports, with the bottom ends of the brackets fixed by bolts.

[0011] By adopting the above technical solution, multiple supports are fixed on the bottom surface of the dissolving cylinder for support, and brackets set at the bottom of the multiple supports support the supports. The brackets are fixed and assembled with bolts to maintain the stability of the support.

[0012] Optionally, a spring is vertically installed between the bracket and the support, with the two ends of the spring fixed to the adjacent end faces of the bracket and the support, respectively.

[0013] By adopting the above technical solution, the spring vertically installed between the support and the bracket provides the deformation of the support and the bracket under the later vibration state through the spring between the support and the bracket on the melting cylinder.

[0014] Optionally, a support bar is vertically fixed on the top surface of the bracket, and a perforated plate is horizontally fixed on the top surface of the support bar, with a hydraulic rod vertically fixed on the perforated plate at the top of the support bar.

[0015] By adopting the above technical solution, a vertically fixed support bar on the top surface of the support is used to vertically guide the vertical displacement of the perforated plate on the top of the support bar to open the dissolving cylinder for water-soluble bag dissolution test.

[0016] Optionally, a guide rod is vertically fixed on the top surface of the cover, and the guide rod slides vertically through the perforated plate of the support bar, and the top surface of the cover is fixedly connected to the output end of the hydraulic rod.

[0017] By adopting the above technical solution, the cover is pushed by the extension and retraction of the hydraulic rod to slide vertically on the perforated plate of the support bar, thereby causing the cover to open and close on the melting cylinder.

[0018] Optionally, a screw is vertically fixed at the center of the bottom surface of the cover, and multiple mesh shells are vertically arranged on the screw along the vertical direction. The filter hole diameter on the multiple mesh shells decreases sequentially along the vertical direction, and a spiral tube is vertically fixed through the middle of the multiple mesh shells, and the spiral tube is threadedly assembled and connected to the screw.

[0019] By adopting the above technical solution, in order to test the particle size after the pesticide is dissolved in the water-soluble bag, multiple mesh shells with different filter holes are assembled vertically on the screw of the cap. The filter hole diameters on the multiple mesh shells decrease sequentially in the vertical direction, thus lifting and retrieving the particle size after the pesticide is dissolved in the water-soluble bag.

[0020] Optionally, a vibration motor is vertically fixed to the outer vertical end face of the support bar.

[0021] By adopting the above technical solution, the vibration motor on the outside of the starting support bar during use drives the spring between the bracket and the support on the dissolving cylinder to deform, and the shaking dissolving cylinder helps to accelerate the dissolution rate of the water-soluble bag.

[0022] In summary, this application includes at least one of the following beneficial technical effects: During the dissolution test of pesticide water-soluble bags, the pesticide water-soluble bag is placed inside the dissolution cylinder. To facilitate temperature control within the dissolution cylinder, a heating rod inside the oil tank is activated via a temperature control switch to heat the oil inside the oil tank. After the oil inside the oil tank is heated to a fixed temperature, it contacts the outer wall of the dissolution cylinder, providing constant-temperature heating for the pesticide water-soluble bag during the dissolution test. By controlling the temperature during the pesticide water-soluble bag test, the accuracy of temperature control is ensured, maintaining a consistent temperature during the dissolution test and improving the precision of the water-soluble bag dissolution test.

[0025] The present application will be further described in detail below with reference to the accompanying drawings.

[0026] This application discloses a pesticide water-soluble bag dissolution tester. (Refer to...) Figure 1 , Figure 2 , Figure 3 and Figure 4 A pesticide water-soluble bag dissolution tester includes a dissolution component 1 and a sealing component 2. The dissolution component 1 includes a dissolution cylinder 11 and an oil shell 12. The top surface of the dissolution cylinder 11 is open, and a discharge pipe 111 is vertically connected and fixed on the bottom surface of the dissolution cylinder 11. A valve is installed on the discharge pipe 111. The oil shell 12 is fixedly fitted on the outside of the dissolution cylinder 11, and heat-conducting oil is added inside the oil shell 12. Multiple heating rods 121 are evenly and vertically fixed inside the oil shell 12, and a temperature control switch 122 is fixed on the top surface of the oil shell 12. The temperature control switch 122 is connected in series to the power supply line of the multiple heating rods 121, and the power transmission terminal of the temperature control switch 122 is electrically connected to the power supply line. The sealing component 2 includes a sealing cap 21, which can be lifted and inserted into the top opening of the dissolution cylinder 11.

[0027] By adopting the above technical solution, when conducting a dissolution test on the pesticide water-soluble bag, the pesticide water-soluble bag is placed inside the dissolution cylinder 11. To facilitate control of the dissolution temperature in the dissolution cylinder 11, the heating rod 121 inside the oil shell 12 is activated by the temperature control switch 122 to heat the heating oil inside the oil shell 12. After the heating oil inside the oil shell 12 is heated to a fixed temperature, it contacts the outer wall of the dissolution cylinder 11, and the pesticide water-soluble bag being tested is heated at a constant temperature for testing. By controlling the temperature of the pesticide water-soluble bag during the test, the accuracy of temperature control during the test is ensured, and the temperature of the water-soluble bag during the dissolution test is kept at the same standard, thus improving the accuracy of the water-soluble bag dissolution test.

[0028] Reference Figure 3An insulation sleeve 13 is provided on the outer wall of the oil tank 12, and the insulation sleeve 13 is fixed to the outer wall of the oil tank 12. In order to prevent heat loss in the oil tank 12 and improve the heat utilization rate in the oil tank 12, the insulation sleeve 13 is wrapped around the outer wall of the oil tank 12 to reduce the heat loss in the oil tank 12 through the outer wall of the oil tank 12.

[0029] Reference Figure 4 Multiple supports 112 are vertically fixed to the bottom surface of the dissolving cylinder 11, and brackets 113 are vertically arranged below the bottom surfaces of the supports 112, with the bottom ends of the brackets 113 fixed by bolts. During use, the multiple supports 112 fixed to the bottom surface of the dissolving cylinder 11 provide support, while the brackets 113 at the bottom ends of the supports 112 support and lift the supports 112. The brackets 113 are assembled and fixed by bolts to maintain support stability. A spring 114 is vertically arranged between the supports 112 and the brackets 113, with both ends of the spring 114 fixed to the adjacent end faces of the supports 112 and the brackets 113, respectively. The spring 114 vertically arranged between the supports 112 and the brackets 113 on the dissolving cylinder 11 provides deformation of the supports 112 and the brackets 113 under subsequent vibration conditions. A support bar 26 is vertically fixed on the top surface of the bracket 112, and a perforated plate is horizontally fixed on the top surface of the support bar 26. A hydraulic rod 27 is vertically fixed on the perforated plate at the top of the support bar 26. In use, the support bar 26, which is vertically fixed on the top surface of the bracket 112, is used to vertically guide the cap 21 to vertically move on the perforated plate at the top of the support bar 26 to open the dissolving cylinder 11 for water-soluble bag dissolution test.

[0030] Reference Figure 5 A guide rod 25 is vertically fixed on the top surface of the cover 21, and the guide rod 25 slides vertically through the perforated plate of the support bar 26. The top surface of the cover 21 is fixedly connected to the output end of the hydraulic rod 27. Under the extension and retraction of the hydraulic rod 27, the guide rod 25 on the cover 21 slides vertically on the perforated plate of the support bar 26, causing the cover 21 to open and close on the dissolving cylinder 11. A screw 22 is vertically fixed at the center of the bottom surface of the cover 21, and multiple mesh shells 23 are vertically arranged on the screw 22. The filter hole diameter on the multiple mesh shells 23 decreases sequentially along the vertical direction, and a spiral tube 24 is vertically fixed through the middle of the multiple mesh shells 23, and the spiral tube 24 is threadedly connected to the screw 22. To test the particle size after pesticides are dissolved in the water-soluble bag, multiple mesh shells 23 with different filter holes are assembled vertically on the screw 22 of the cap 21. The particle size after pesticides are dissolved in the water-soluble bag is lifted and retrieved by the filter holes on the multiple mesh shells 23 decreasing in diameter in the vertical direction.

[0031] Reference Figure 4 and Figure 5A vibration motor 28 is vertically fixed on the outer vertical end face of the support 26. During use, the vibration motor 28 on the outer side of the support 26 is activated, which causes the spring 114 between the bracket 112 and the support 113 on the dissolving cylinder 11 to deform. The shaking of the dissolving cylinder 11 helps to accelerate the dissolution rate of the water-soluble bag.

[0032] The implementation principle of the pesticide water-soluble bag dissolution tester in this application embodiment is as follows: During the dissolution test of the pesticide water-soluble bag, the pesticide water-soluble bag is placed inside the dissolution cylinder 11. To facilitate control of the dissolution temperature in the dissolution cylinder 11, the heating rod 121 inside the oil shell 12 is activated by the temperature control switch 122 to heat the heating oil inside the oil shell 12. After the heating oil inside the oil shell 12 is heated to a fixed temperature, it contacts the outer wall of the dissolution cylinder 11, thus conducting a constant-temperature heating test on the pesticide water-soluble bag in the dissolution cylinder 11. The dissolution test is performed by controlling the temperature of the pesticide water-soluble bag. To ensure accurate temperature control during pesticide water-soluble bag testing, the cover 21, under the extension and retraction of the hydraulic rod 27, pushes the guide rod 25 on the cover 21 to slide vertically on the perforated plate of the support 26, causing the cover 21 to open and close on the dissolving cylinder 11. In order to test the particle size of the pesticide after dissolving in the water-soluble bag, multiple mesh shells 23 with different filter holes are assembled vertically on the screw 22 of the cover 21. As the filter hole diameters on the multiple mesh shells 23 decrease sequentially in the vertical direction, the vibration motor 28 on the outside of the support 26 is activated, causing the spring 114 between the bracket 112 and the support 113 on the dissolving cylinder 11 to deform. The shaking dissolving cylinder 11 helps to accelerate the dissolution rate of the water-soluble bag.

[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
