Description

Technical Field

[0001] This utility model relates to the field of chemical storage equipment technology, specifically a chemical raw material storage tank. Background Technology

[0002] In chemical experiments and production processes, the storage and handling of liquid chemical raw materials are crucial. Existing liquid chemical raw material storage tanks mostly only have basic storage functions and are significantly inadequate in terms of quantitative extraction and safety protection. Traditional storage tanks rely on manual pouring or simple liquid extraction devices to extract raw materials, which makes it difficult to extract quantitatively. Excessive or insufficient extraction can easily affect the accuracy of experiments / production. Moreover, liquid spillage is prone to occur during pouring, causing safety risks such as corrosion and combustion. Existing storage tanks lack real-time monitoring of internal temperature and pressure, which can easily lead to a sudden increase in internal pressure and deterioration of raw materials due to environmental changes or raw material characteristics, affecting usage plans.

The quantitative extraction mechanism 12 includes a storage box 13 and a storage pipe 17. A first limiting plate 26 is fixedly installed on the outside of the storage box 13 inside the storage pipe 17. A second limiting plate 27 is fixedly connected to the outer side of the tube 17. The outer side of the first limiting plate 26 and the inner side of the second limiting plate 27 both have a certain curvature, fitting against the inner and outer sides of the storage tube 17 to limit the storage box 13 and prevent it from falling out of the equipment. A magnetic plate 23 is fixedly connected to the inner wall of the storage tube 17. An auxiliary fixing plate 24 is slidably connected to one side of the magnetic plate 23. A first auxiliary rod 10 is fixedly connected to the top of the auxiliary fixing plate 24. The first auxiliary rod 10 passes through the top of the storage tube 17 and is slidably connected to it. A push-pull rod 5 is fixedly connected to the top of the first auxiliary rod 10. The auxiliary fixing plate 24 is made of 403 stainless steel. The installation of the push-pull rod 5 makes the movement of the first auxiliary rod 10 more convenient. Several fixed adjustment blocks 25 are fixedly connected to the side of the auxiliary fixing plate 24 away from the magnetic plate 23. A piston head 31 is fixedly connected to the bottom of the auxiliary fixing plate 24. A rubber anti-leakage sleeve 32 is fixedly installed on the outside of the piston head 31 to prevent liquid from entering the top of the piston head 31. The discharge pipe 15 is fixedly connected to and communicates with the storage pipe 17. A second valve 16 is fixedly installed at the bottom of the storage pipe 17. A sliding groove 38 is opened on one side of the storage pipe 17.

The sliding adjustment block 28 is located inside the internal mounting groove 33 and is slidably connected to it. A connecting rope 37 is fixedly connected to the end of the sliding adjustment block 28 near the first spring 30, and a pull ring 29 is fixedly connected to the end of the connecting rope 37 away from the sliding adjustment block 28. The storage box 13 has a through groove for the connecting rope 37 to slide. The sliding adjustment block 28 cooperates with the fixed adjustment block 25.

[0018] In summary, when storing chemical raw materials into this chemical raw material storage tank, the dust cover 3 can be opened to pour out the raw materials, such as ethanol, acetone, glycerol, and mineral oil. The raw materials fall through the filter screen 18 into the funnel 19 and then flow into the tank body 1 through the bottom of the funnel 19. Once all the raw materials have entered the tank body 1 (which can be made of stainless steel), the dust cover 3 can be reinstalled on the outside of the feeding pipe 4. When a specific amount of raw material needs to be extracted, the receiving box 13 is pressed down, causing the sliding adjusting block 28 to return to the inner mounting groove 33 along the inclined surface of the fixed adjusting block 25. Inside, after the fixed adjusting block 25 is moved, the sliding adjusting block 28 returns to its original position under the action of the first spring 30. Releasing the storage box 13 causes it to spring back to its initial position due to the two second springs 36, causing the sliding adjusting block 28 to slide upwards. This, in turn, causes the fixed adjusting block 25 and the auxiliary fixing plate 24 to slide upwards. Because a magnetic plate 23 is fixedly installed on the inner wall of the storage tube 17, and the magnetic plate 23 has a certain magnetic force, the auxiliary fixing plate 24 is attracted to it and will not shift. When the sliding adjusting block 28 slides downwards, it will not cause the auxiliary fixing plate 24 to shift, but when the sliding adjusting block 28 slides upwards, it will move upwards accordingly. As the fixing plate 24 moves upward, the piston head 31 moves upward simultaneously. At this time, due to the negative pressure environment inside the storage pipe 17, the liquid inside the tank 1 is drawn into the storage pipe 17 along the discharge pipe 15. Each downward press of the collection box 13 extracts the same amount of liquid, two milliliters per press. By observing the glass installed inside the viewing window 35, the sliding adjustment block 28 stops after moving a certain number of fixed adjustment blocks 25. The second valve 16 is then opened, and the pull ring 29 is pulled away from the equipment, causing it to move the sliding adjustment block 28 back into the inner mounting groove 33. The push-pull rod 5 is pressed down, causing the first auxiliary rod 10, auxiliary fixing plate 24 and piston head 31 to slide down, so that the liquid inside the storage tube 17 is discharged through the second valve 16. When the liquid level inside the instrument is low, the liquid inside the instrument can be discharged through the first valve 9. Because the bottom surface inside the instrument has a certain slope, the raw materials inside the instrument will not remain inside the instrument and will be discharged smoothly. When the material is stored, the temperature and pressure of the material inside the instrument can be monitored by the pressure transmitter 7 and the temperature sensor 8, and the data can be wirelessly transmitted to terminals such as mobile phones to prevent the raw materials from deteriorating.

[0019] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
