Description

Technical Field

[0001] The utility model relates to the technical field of gel mixing, in particular to a mixing device for the production of time-delay controllable polymer gel. Background Art

[0002] Time-delayed controllable polymer gel is a special material with a wide range of applications in medicine and bioengineering. In the medical field, polymer gel is used as a drug delivery system with good biocompatibility and controllable drug release properties. In the bioengineering field, time-delayed controllable polymer gel is also widely used as an ideal cell carrier. When the time-delayed controllable polymer gel is not fully solidified or cross-linked, it exhibits properties similar to those of a viscous fluid. Once it is fully cross-linked and solidified, it will transform into a solid or semi-solid gel structure and no longer have the fluidity of a fluid.

[0003] During the mixed production of polymer gel, since the gel becomes a fluid at this time, when the stirring blade is removed from the stirring tank, a small amount of mixture will adhere to the surface of the stirring blade, requiring manual secondary scraping. If the material on the stirring blade is not collected, the output of the polymer gel is reduced, resulting in a waste of resources. Therefore, it is necessary to propose a delayed and controllable mixing equipment for polymer gel production. Summary of the invention

[0004] The purpose of the utility model is to provide a mixing device for producing a time-delayed and controllable polymer gel, so as to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a mixing device for delayed controllable polymer gel production, comprising a base, the upper surface of the base is symmetrically fixedly connected to a support block, the outer walls of the two support blocks are penetrated with a concave hole, the inner walls of the two concave holes are slidably connected to a slider, one end of the two sliders extends into the support block and is commonly fixedly connected to a mixing drum, and the inner wall of the mixing drum is slidably connected to a sealing plug;

[0006] The lower surface of the sealing plug is fixedly connected to a top block, the upper surface of the base is fixedly connected to a mounting platform, the lower surface of the mounting platform is rotatably connected to a driving rod, the outer wall of the driving rod is symmetrically fixedly connected to a stirring blade, the two stirring blades and the outer wall of the driving rod are slidably connected to a cleaning block, and the interior of the cleaning block is symmetrically penetrated with a cavity;

[0007] The inner walls of the two cavities are slidably connected to the limiting blocks, and limiting holes are penetrated through the outer walls of one side of the two stirring blades relative to the position of the limiting blocks. One end of the two limiting blocks extends into the corresponding limiting holes, and the other ends of the two limiting blocks extend outside the cleaning block.

[0008] Preferably, a driving motor is fixedly connected to the upper surface of the mounting platform relative to the driving rod, and one end of the driving rod extends to the outside of the mounting platform through a bearing and is fixedly connected to the driving motor through a coupling.

[0009] Preferably, the upper surface of the base is fixedly connected to a hydraulic cylinder on one side of the support block, and the two sliding blocks are fixedly connected to the hydraulic cylinder on the same side.

[0010] Preferably, outer walls of one end of the two limit blocks located in the cavity are fixedly connected with springs, and the other ends of the two springs are fixedly connected to the cleaning block.

[0011] Preferably, the driving rod is symmetrically fixedly connected with a stopper at the position of the stirring blade.

[0012] Preferably, the two limit blocks are arranged in an I shape.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows: the hydraulic cylinder is started to push the mixing drum to move to one side of the mixing blade, and the gel raw materials are mixed by the mixing blade. After mixing, the hydraulic cylinder is started to push the mixing drum out from the outside of the mixing blade, and the spring pushes the limit block out from the limit hole. The cleaning block scrapes off the mixture adhering to the surface of the mixing blade. When the polymer reaction is completed, the hydraulic cylinder is started to drive the mixing drum to move to the bottom end, and the top block pushes the polymer out of the mixing drum through the sealing plug. The mixture adhering to the surface of the mixing blade can be scraped off, reducing the waste of resources, and the polymer after the reaction is completed can be pushed out of the mixing drum, reducing the labor intensity of the staff.
