Description

Technical Field

[0001] This utility model relates to the field of chemical production technology, specifically a raw material dilution device for the research and development of chitosan hyperbranched polyamide-amine demulsifier. Background Technology

[0002] Chitosan hyperbranched polyamide-amine demulsifier is a novel, highly efficient demulsifier based on natural high-molecular-weight chitosan, which incorporates a hyperbranched polyamide-amine (PAMAM) structure through chemical modification. Its development combines the biocompatibility of natural high-molecular-weight polymers with the unique properties of hyperbranched polymers, demonstrating significant advantages in fields such as oilfield produced water treatment and industrial wastewater treatment.

[0003] In the production process of demulsifiers, it is often necessary to dilute the raw materials of the demulsifier. The raw materials are diluted to different degrees by a dilution device to produce demulsifiers of different concentrations. When diluting the raw materials, the existing dilution device has a fixed stirring structure position, resulting in a low mixing rate of the raw materials. In order to avoid the impact of particulate impurities in the demulsifier raw materials on the quality, the raw materials usually need to be filtered before being added to the dilution tank, which is quite inconvenient. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 5 As shown, a raw material dilution device for the research and development of chitosan hyperbranched polyamide-amine demulsifier includes a tank 1, a stirring mechanism installed inside the tank 1, a feeding hopper 2 on the upper side, a discharge pipe 3 on the bottom side, a valve installed on the discharge pipe 3, and a PLC controller installed on the upper side of the tank 1.

[0023] The stirring mechanism includes a stirring shaft 4 that passes through and is rotatably mounted on the top of the tank body 1. A spiral blade 5 is mounted on the lower side of the stirring shaft 4, and a geared motor 6 is connected to the top. Multiple stirring shafts 7 are installed through the top edge of the tank body 1. Blades 8 are mounted on the lower part of the stirring shafts 7. A sleeve 9 is rotatably mounted on the top of the tank body 1 and slidably fitted on the outside of the stirring shafts 7. A gear 10 is mounted on the upper part of the stirring shaft 4, and a gear 11 that meshes with the gear 10 is mounted on the outside of the sleeve 9. A protective cover 13 is fixedly connected to the top of the tank body 1. The protective cover 13 is located outside the gears 10 and 11. The geared motor 6 is mounted on the top of the protective cover 13, and the stirring shafts 7 pass through the protective cover 13. Two limiting grooves are symmetrically opened on the side of the stirring shafts 7. Limiting blocks 16 are symmetrically fixed on the inner wall of the sleeve 9, and the limiting blocks 16 are slidably connected to the limiting grooves.

[0024] The geared motor 6 drives the stirring shaft 4 and the blade 5 to rotate, which can achieve the initial mixing and homogenization of the raw materials. The stirring shaft 4 drives the gear 10 to rotate, the gear 10 drives the gear 11 and the sleeve 9 to rotate, and the sleeve 9 drives the stirring shaft 7 and the blade 8 to rotate through the limiting block 16, which can achieve the secondary mixing and homogenization of the raw materials. Furthermore, through the cooperation of the blade 5 and the blade 8, the mixing and dilution rate of the raw materials can be improved.

[0025] The top of the tank 1 is equipped with a drive assembly for driving the stirring shaft 7 to rise and fall. The drive assembly includes multiple electric push rods 14 mounted on the top of the protective cover 13. The output end of the electric push rods 14 is connected to a connecting frame 15. The top of the stirring shaft 7 is rotatably connected to the connecting frame 15.

[0026] The extension and retraction of the electric actuator 14 allows the connecting frame 15 to move up and down. When the connecting frame 15 moves, it simultaneously drives the stirring shaft 7 to move, thereby enabling the adjustment of the height of the impeller 8. By adjusting the height of the impeller 8, the mixing and dilution rate of the raw materials can be further improved.

[0027] A filter cylinder 12 is detachably installed inside the feeding hopper 2, and a cleaning component is installed inside the filter cylinder 12. A positioning ring 17 is fixedly connected to the upper inner part of the feeding hopper 2. Two ear plates 18 are symmetrically fixedly connected to the upper side of the filter cylinder 12. The ear plates 18 are made of iron and have a handle 19 installed on their top. The positioning ring 17 has a slot that matches the ear plates 18, and a magnet 20 is embedded in the slot. The cleaning component includes a horizontal plate 21 fixedly installed on the top of the filter cylinder 12. A rotating shaft 22 is mounted through and rotatably on the horizontal plate 21. Cleaning brushes 23 are installed on the side and bottom of the rotating shaft 22, abutting against the inner side and bottom surface of the filter cylinder 12. A handwheel 24 is installed on the top of the rotating shaft 22.

[0028] The filter cartridge 12 allows for the filtration of demulsifier raw materials during addition, preventing particulate matter from entering the tank 1. By rotating the shaft 22 via the handwheel 20, the cleaning brush 23 can be rotated, preventing impurities from clogging the filter cartridge 12 and ensuring filtration efficiency. The filter cartridge 12 can be removed by pulling up the ear plate 18 via the handle 19, and the impurities inside can be cleaned.

[0029] In practical use, the raw materials and diluent of chitosan hyperbranched polyamide-amine demulsifier are added into tank 1 through feed hopper 2. Filter cylinder 12 filters the demulsifier raw materials to prevent particulate matter from entering the tank 1. Gear motor 6 drives blade 1 5 and blade 2 8 to rotate, and electric push rod 14 drives blade 2 8 to move up and down, which can realize the rapid mixing of raw materials.
