[0002] Chemical equipment is the general term for machines and equipment used in chemical industry production. In chemical industry production, in order to process raw materials into finished products of a certain specification, a series of chemical processes such as pretreatment of raw materials, chemical reactions, and separation and purification of reaction products are often required. The machinery used to realize the above processes is usually classified as chemical equipment. And chemical barrels are the most basic and widely used ones in chemical equipment. After being used for a period of time, residues will accumulate on the inner wall of the chemical barrel, and the accumulation of residues will seriously affect the effect of chemical reactions, directly leading to the decline in the quality of chemical products. Therefore, in chemical industry production, chemical barrels need to be frequently cleaned. At present, the existing cleaning method is mainly manual cleaning, and only a small number of cleaning devices are applied to the cleaning of chemical barrels. Due to the chemical properties (such as volatility, corrosiveness, etc.) of the residues accumulated in the chemical barrels and the cleaning liquid used for cleaning, if the protective measures of the cleaning personnel are not good, it will cause harm to the health of the cleaning personnel. Moreover, the efficiency of manually cleaning chemical barrels is low, resulting in high labor costs and time costs. When using the existing cleaning devices to clean chemical barrels, problems such as excessive consumption of cleaning liquid, incomplete recovery, and poor cleaning effect will occur, which not only causes waste of cleaning liquid and increases production costs, but also affects the quality of chemical products in chemical industry production for the chemical barrels that are not thoroughly cleaned.

[0003] Therefore, a chemical barrel cleaning device for chemical production is proposed. Content of the Utility Model

Detailed implementation manners

[0016] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0017] Please refer to Figures 1 - 3 , the present invention provides a technical solution: a chemical barrel cleaning device for chemical production, including a rotating shaft 1. The bottom of the rotating shaft 1 is rotatably connected to a base 2. The base 2 has a circular structure. A suction cup is provided on the lower surface of the base 2 for sucking the bottom of the chemical barrel to position the device. A radially arranged positioning rod 3 is provided on the outer wall of the rotating shaft 1. One end of the positioning rod 3 away from the axis of the rotating shaft 1 is respectively movably provided with a movable rod 4. One end of the movable rod 4 away from the rotating shaft 1 is fixedly connected to a strip-shaped rod 5. The strip-shaped rod 5 is arranged parallel to the rotating shaft 1. A strip-shaped cavity 6 extending in the same direction is arranged inside the strip-shaped rod 5. A plurality of water spray nozzles are provided through the side wall of the strip-shaped rod 5. A cleaning brush 7 is fixedly connected to the outer surface of the strip-shaped rod 5. When the device is used, it is placed inside the chemical barrel. The rotating shaft 1 is coaxially arranged with the chemical barrel. A connecting pipe communicating with the internal strip-shaped cavity 6 is provided at the upper end of the strip-shaped rod 5. The connecting pipe is connected to an external water supply mechanism. After the cleaning water is injected, it is evenly sprayed out from the water spray nozzles. At the same time, the positioning rod 3 is rotated to drive the strip-shaped rod 5 to rotate, and the cleaning brush 7 is attached to the inner wall of the chemical barrel to clean the chemical barrel;

[0018] Specifically, a movable tube 8 is sleeved and movably arranged on the outer peripheral surface of the rotating shaft 1. The movable tube 8 is coaxially arranged with the rotating shaft 1. A plurality of limiting grooves 9 extending in the same direction are arranged on the outer peripheral surface of the rotating shaft 1. A limiting strip 10 movably connected to the limiting grooves 9 is arranged on the inner wall of the movable tube 8. The positioning rod 3 is fixedly connected to the movable tube 8, so that the sliding of the movable rod 4 can be controlled. The cleaning brush 7 is attached to the inner wall of the chemical barrel, and then the rotating shaft 1 is controlled to move downward, and the base 2 is attached to the inner wall of the chemical barrel to complete the installation of the device. Then, when the rotating shaft 1 rotates, the movable tube 8 can be driven to rotate synchronously. The movable tube 8 drives the positioning rod 3 to rotate, and further drives the strip-shaped rod 5 to rotate;

[0019] Specifically, a through groove is provided on the upper side wall of the positioning rod 3 at the upper end corresponding to the outside of the movable tube 8. An adjusting ring 11 is rotatably provided inside the through groove. Rack bars 12 are fixedly connected to the closer ends of the movable rods 4 respectively. Teeth meshing with the rack bars 12 are provided on the outer wall of the adjusting ring 11. Thus, when the adjusting ring 11 is rotated, the rack bars 12 can be driven to move synchronously in the reverse direction. The movable rods 4 are driven to move synchronously by the rack bars 12, so that the cleaning brush 7 fits against the inner wall of the chemical barrel, and at the same time, the centering of the rotating shaft 1 is ensured.

[0020] Specifically, a positioning ring 13 is provided on the surface of the positioning rod 3 corresponding to the outside of the adjusting ring 11. Ratchet teeth are provided on the surface of the adjusting ring 11 inside the positioning ring 13. Pawls cooperating with the ratchet teeth are provided on the inner wall of the positioning ring 13 to ensure the one-way rotation of the positioning ring 13. After the cleaning brush 7 abuts against the inner wall of the chemical barrel, it does not need to be fixed. A knob (not shown in the figure) for controlling the rotation of the pawl can be provided outside the positioning ring 13 to facilitate the disassembly of the device.

[0021] Specifically, the movable rod 4 includes a first movable rod 401 movably connected to the positioning rod 3. A second movable rod 402 is movably arranged inside the first movable rod 401. The strip-shaped rod 5 is fixedly connected to the second movable rod 402. An elastic element is arranged between the first movable rod 401 and the second movable rod 402. The elastic element can be a spring. Under the action of the elastic element, the first movable rod 401 can slide relative to the second movable rod 402. When the movable rod 4 is controlled to move outward, after the cleaning brush 7 abuts against the inner wall of the chemical barrel, the movable rod 4 can continue to be controlled to move, so that the first movable rod 401 slides relative to the second movable rod 402 against the elastic element, and the cleaning brush 7 can be pressed tightly against the inner wall of the chemical barrel, and the cleaning effect is better.

[0022] When the utility model is in use, after the device is placed inside the chemical barrel, the adjusting ring 11 is rotated. The adjusting ring 11 drives the rack bars 12 to slide through the teeth. The movable rods 4 are driven to move synchronously by the rack bars 12. The movable rods 4 drive the strip-shaped rod 5 to move, so that the strip-shaped rod 5 drives the cleaning brush 7 to fit against the inner wall of the chemical barrel. Then, the rotating shaft 1 is slid downward to make the base 2 fit against the inner wall of the chemical barrel. Then, while injecting cleaning water into the strip-shaped cavity 6, the rotating shaft 1 is rotated. The rotating shaft 1 drives the movable tube 8 to rotate, and the movable tube 8 drives the positioning rod 3 and the movable rods 4 to rotate. While the cleaning water is sprayed out from the water spraying port, the cleaning brush 7 cleans the inner wall of the chemical barrel.
