Abstract
Description
Technical Field
[0001] This utility model relates to the field of pesticide formulation testing technology, specifically a pesticide formulation flash point testing system. Background Technology
[0002] The flash point test refers to the lowest temperature at which the vapor emitted by a flammable liquid, after mixing with air to form a flammable mixture and reaching a certain concentration, will flash and ignite upon contact with an ignition source. The flash point is not only an important indicator of whether a liquid substance is flammable, but also a safety indicator for the storage, transportation, and use of flammable liquids.
[0003] Flash point testing of pesticide formulations requires heating the outside of the container to achieve the effect of heating the pesticide formulation for flash point testing. However, if the container is overheated, it is difficult to remove it from the flash point testing device, which slows down the testing of the next pesticide formulation, reduces work efficiency, and the internal temperature is not easy to dissipate, which can also affect the test results of other pesticide formulations.

[0014] (III) Beneficial Effects
[0015] Compared with the prior art, this utility model provides a pesticide formulation flash point testing system, which has the following beneficial effects:
[0016] This pesticide flash point testing system, after the pesticide flash point test is completed, simultaneously activates the pump and cooling fan. The cooling fan blows air into the flash point testing chamber, accelerating airflow. Simultaneously, the pump draws cold water from the water tank into the serpentine tube, generating cold air. The cooling fan blows this cold air into the flash point testing chamber, cooling the loading cup inside the container, thus rapidly lowering its temperature. The cooled loading cup can then be quickly removed, improving testing efficiency and enhancing practicality. Furthermore, the cold water flows through the serpentine tube into the refrigerator, where it is cooled and then flows back into the water tank, achieving water recycling and ensuring the water inside the tank remains at a consistently low temperature.

[0022] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1-4 A flash point testing system for pesticide formulations includes a flash point testing chamber 1, a base 2 at the bottom of the flash point testing chamber 1, a flame generator 3 on one side of the top of the flash point testing chamber 1, heat dissipation holes 4 on the side of the flash point testing chamber 1, an air inlet 5 on the other side of the flash point testing chamber 1, a cooling fan 6 inside the air inlet 5, threaded rods 11 at both ends inside the flash point testing chamber 1, a worm gear 17 at the bottom of the threaded rods 11 located inside the base 2, and a movable plate 12 on the threaded rods 11, the movable plate 12 being threadedly connected to the threaded rods 11. A container 13 is provided at one end of the base 2, and a loading cup 14 is provided inside the container 13. A worm gear 15 is provided on one side of the base 2. The worm gear 15 is located on the side of the worm wheel 17 and is meshed with the worm wheel 17. A dual-axis motor 16 is provided in the middle of the worm gear 15. A water tank 7 is provided on the other side of the base 2. A cooler 8 is provided on one side of the water tank 7 and a pump body 9 is provided on the other side of the water tank 7. A serpentine tube 10 is provided on the inner side of the flash point test chamber 1. The serpentine tube 10 is located on the side of the cooling fan 6. One end of the serpentine tube 10 is connected to the pump body 9 and the other end of the serpentine tube 10 is connected to the cooler 8.
[0024] In actual use, the above structure first injects a measured amount of cold water into the water tank 7, then pours the pesticide formulation to be tested into the loading cup 14, and uses the flame generator 3 to generate a flame to perform a flash point test on the pesticide formulation. After the test is completed, the pump body 9 and the cooling fan 6 are turned on simultaneously. The cooling fan 6 blows air into the flash point test chamber 1, accelerating the airflow inside the flash point test chamber 1. At the same time, the pump body 9 draws the cold water from the water tank 7 into the serpentine tube 10, where cold air is generated. The cooling fan 6 then blows cooling air onto the container 13 and the loading cup 14, rapidly reducing the flash point. The water in the serpentine tube 10 is cooled quickly and then enters the cooler 8. After being cooled by the cooler 8, the water returns to the water tank 7, thus achieving water recycling. After the loading cup 14 has cooled down, the dual-axis motor 16 is turned on. The dual-axis motor 16 drives the worm gear 15, which in turn drives the worm wheel 17. The worm wheel 17 drives the threaded rod 11 to rotate. The rotation of the threaded rod 11 drives the moving plate 12, which in turn drives the container 13. The container 13 then lifts the loading cup 14 to the top of the flash point test chamber 1, making it easier to pick up the loading cup 14 and improving the convenience of use.
[0025] In this embodiment, the water tank 7 is provided with an observation window and a water inlet pipe is provided on the side of the water tank 7, which improves the use effect of the water tank 7 and makes it convenient to observe the water storage volume inside the water tank 7.
[0026] In this embodiment, the movable plate 12 is provided with a through hole, and the flash point test chamber 1 is provided with fixed slide rods 18 on both sides. The through hole is slidably sleeved on the fixed slide rods 18, which improves the stability of the movable plate 12 when it slides up and down.
[0027] In this embodiment, anti-slip blocks are provided on both sides of the bottom end of the base 2. The anti-slip blocks are made of rubber, which improves the stability of the base 2.
[0028] In this embodiment, a dustproof mesh is provided on the heat dissipation hole 4. The dustproof mesh is detachably connected to the heat dissipation hole 4, which improves the dustproof effect at the heat dissipation hole 4.
[0029] In this embodiment, the flash point test chamber 1 is provided with a door on its side, and the door is bolted to the flash point test chamber 1 to facilitate the inspection and maintenance of the interior of the flash point test chamber 1.
[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
