Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, specifically a tilting leak-proof chemical drum for chemical manufacturing. Background Technology

[0002] Chemical engineering is an abbreviation for "chemical process," "chemical industry," and "chemical engineering." Any technology that uses chemical methods to change the composition or structure of substances or synthesize new substances falls under the category of chemical production technology, also known as chemical process. The resulting products are called chemicals or chemical products. Chemical manufacturing processes require the use of chemical containers to store liquid chemicals, facilitating long-distance transportation of these liquids.

[0003] In existing technologies, most chemical drums are made of plastic and are sealed to prevent leakage through threaded connections between the lid and the inlet / outlet pipes for the chemical liquid. However, if the lid and inlet / outlet pipes are not properly tightened, accidental tipping of the drum can easily cause leakage, resulting in resource waste and safety hazards. Therefore, we propose a tipping-proof chemical drum for chemical manufacturing. Utility Model Content

[0022] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Please see Figures 1 to 5 This utility model provides a technical solution: a tilting leak-proof chemical drum for chemical manufacturing, comprising: a drum body 1 and a liquid inlet / outlet pipe 5. A movable base 4 is connected to the bottom end of the drum body 1. A sealing cap 7 is threadedly connected to the outer wall of the liquid inlet / outlet pipe 5. A retaining post 9 is installed inside the sealing cap 7, and a first sealing ring 10 is fitted around the retaining post 9. The drum body 1 is fixedly mounted on the top of the movable base 4. Movable wheels 3 are installed at the four corners of the bottom end of the movable base 4. A handle 2 is fixedly connected to one end of the movable base 4 for easy movement of the drum body 1. The liquid inlet / outlet pipe 5 is fixedly mounted on the top of the drum body 1, and its bottom end is connected to the interior of the drum body 1. An external connecting thread 6 is provided on the outer wall of the liquid inlet / outlet pipe 5 for easy addition and extraction of chemical liquids. The inner sidewall of the sealing cover 7 is provided with an internal connecting thread 8. The clamping post 9 is fixedly installed on the inner top wall of the sealing cover 7. The first sealing ring 10 is sleeved on the outer wall of the clamping post 9 near the end of the sealing cover 7, so that the inner top wall of the sealing cover 7 and the top of the liquid inlet / outlet pipe 5 are tightly connected.

[0024] The inner wall of the liquid inlet / outlet pipe 5 is provided with a insertion groove 14. A sealing cylinder 12 is installed inside the insertion groove 14. A second sealing ring 11 is installed on the bottom wall of the inner wall of the insertion groove 14. A limit block 13 is connected to the top side wall of the sealing cylinder 12. The limit block 13 is fixedly installed on the side wall of the sealing cylinder 12. Both the limit block 13 and the side wall of the sealing cylinder 12 are slidably connected to the inner wall of the insertion groove 14, so that the sealing cylinder 12 is not easy to rotate in the insertion groove 14.

[0025] The side wall of the limiting block 13 has a limiting groove 16, and the inner wall of the limiting groove 16 is connected to a limiting block 15. A movable pull rod 18 is slidably installed on the side wall of the barrel 1 near the limiting block 15. A limiting spring 17 is sleeved on the outside of one end of the movable pull rod 18 near the limiting block 15. The inner wall of the insertion groove 14 near the limiting block 15 is connected to a movable groove 19. One end of the limiting block 15 is slidably connected to the inner wall of the movable groove 19. The top of the other end of the limiting block 15 is arc-shaped and slides into the limiting groove 16. When the sealing cylinder 12 is inserted into the insertion groove 14, it squeezes the arc surface of the limiting block 15, causing the limiting block 15 to enter the movable groove 19. The longitudinal section of the movable pull rod 18 is T-shaped. One end of the movable pull rod 18 passes through the barrel 1 and is inserted into the movable groove 19. One end of the movable pull rod 18 and the limiting spring 17 are both fixedly installed on the limiting block 15. The other end of the limiting spring 17 is fixedly installed on the inner side wall of the movable groove 19. When the limiting block 15 enters the movable groove 19, it squeezes the limiting spring 17. When the movable groove 19 and the limiting groove 16 are aligned, the limiting block 15 can be pushed into the limiting groove 16 under the elastic action of the limiting spring 17, thereby realizing the limiting function of the sealing cylinder 12.

[0026] When this device is in operation, the sealing cylinder 12 inside the insertion slot 14, and the second sealing ring 11 between the insertion slot 14 and the sealing cylinder 12, can initially seal the liquid inlet / outlet pipe 5. The limiting block 15, which is slidably installed inside the moving slot 19, can be inserted into the limiting slot 16 under the elastic action of the limiting spring 17 to limit the sealing cylinder 12. The sealing cover 7, which is threaded to the outer wall of the liquid inlet / outlet pipe 5, and the first sealing ring 10 between the sealing cover 7 and the liquid inlet / outlet pipe 5, can reseal the liquid inlet / outlet pipe 5. The sealing cylinder 12 can be pressed tightly by the pressing post 9 inside the sealing cover 7, which strengthens the sealing effect of the liquid inlet / outlet pipe 5. This solves the problem that if the lid and the liquid inlet / outlet pipe are not screwed in properly, the chemical liquid will easily leak when the barrel is accidentally tilted, which will not only waste resources but also pose a safety hazard.

[0027] 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.
