Description

Technical Field

[0001] This utility model relates to the field of gel production and preparation technology, specifically to an automatic mixing device for rapid gel preparation. Background Technology

[0002] The preparation of polyacrylamide gel involves mixing various reagents such as acrylamide, ammonium persulfate, tetramethylethylenediamine, SDS, Tris-HCl, and water. Different gel concentrations are required depending on the type and molecular weight of the substances being separated. Furthermore, the required reagent dosages differ significantly between discontinuous gels, stacking gels, and separating gels. Manual operation requires constant attention to reagent ratios, as accidental reagent additions are common. In addition, acrylamide and tetramethylethylenediamine are highly neurotoxic, posing a significant hazard to laboratory personnel. Therefore, the entire polyacrylamide gel preparation process is cumbersome, time-consuming, and labor-intensive. Moreover, large-scale preparation of polyacrylamide gel is not feasible. The molten gel solution must be poured into a gel-forming plate with a comb-like plate. However, these comb-like plates are typically narrow and thin, usually 1-1.5 mm. Pouring the hot gel solution can cause deformation of the comb-like plate, while pouring it at low temperatures can lead to solidification of the subsequent gel solution. Therefore, it is impossible to prepare large quantities of polyacrylamide gel in a single batch. However, the process of preparing gels in small batches and multiple times requires repeated weighing, heating, and cooling steps, which consumes a significant amount of time and reduces work efficiency. Therefore, we propose an automated mixing device for rapid gel preparation. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] An automated mixing device for rapid gel preparation, such as Figures 1-4 As shown, it includes a storage tank 1; the storage tank 1 is equipped with a stirring mechanism 2, which can continuously stir the turbid liquid of the gel raw material to make the raw material evenly dispersed in the water. The top of the storage tank 1 is provided with a feed inlet for feeding the gel raw material.

[0026] Specifically, the stirring mechanism 2 includes a support rod 201, which is rotatably connected to the top of the storage tank 1, providing support for the entire stirring mechanism 2. A heating coil 202 is sleeved on the outside of the support rod 201, heating it and transferring the heat to the stirring mechanism 2, thus achieving uniform heating of the gel material. A stirring frame 203 is fixedly connected to the bottom of the support rod 201, continuously heating the gel material inside the storage tank 1. A stirring blade 204 is rotatably connected to the side of the stirring frame 203, increasing the stirring range and improving the stirring effect on the gel material. The support rod 201, stirring frame 203, and stirring blade 204 are all made of thermally conductive materials, ensuring uniform heat transfer to the material during stirring and increasing the melting speed of the gel material. A column 205 is fixedly connected to the bottom of the storage tank 1, and a baffle 206 is fixedly connected to the side of the column 205. The baffle 206 can block the top or bottom of the side of the stirring blade 204, so that the stirring blade 204 swings as it rotates around the column 205, forming multiple vortices inside the raw material and improving the mixing effect.

[0027] Furthermore, the stirring rack 203 has a spiral structure and is hollow, which facilitates the subsequent flow of the gel solution. An inlet pipe 207 is fixedly connected to the bottom of the stirring rack 203. The inlet pipe 207 is sleeved on the outer bottom of the column 205, allowing the column 205 to be fixed inside the storage tank 1 while facilitating the rotational connection of the inlet pipe 207 to the bottom of the column 205. A sleeve 208 is fitted outside the inlet pipe 207, and an inlet hole 209 is opened on the side of the inlet pipe 207. The sleeve 208 is slidably connected to the outside of the inlet pipe, allowing the opening and closing of the inlet hole 209 to be controlled by sliding the sleeve 208. A motor is fixedly connected to the top of the storage tank 1, and the motor output shaft drives the support rod 201 via a transmission belt.

[0028] Example 2

[0029] like Figures 1-5 As shown, based on Example 1, a liquid dispensing mechanism 3 is fixedly connected to the side of the storage tank 1. The liquid dispensing mechanism 3 can conveniently dispense the melted gel, thereby introducing the gel into the mold for easy gel molding.

[0030] In this embodiment, the liquid dispensing mechanism 3 includes a support tube 301, which is rotatably connected to the top of the stirring frame 203. The support tube 301, rotatably connected to the top of the stirring frame 203, can maintain a constant direction when rotating, thus facilitating the guidance of the gel liquid in a specific direction. A liquid outlet 302 is provided at the top of the stirring frame 203. The structure of the liquid outlet 302 allows for easy communication between the support tube 301 and the stirring frame 203, allowing the gel liquid to flow from inside the stirring frame 203 into the support tube 301. A corrugated pipe 303 is connected to the end of the support tube 301. The corrugated pipe 303 can guide the gel liquid inside the support tube 301, and its structure can be easily extended or shortened, thus facilitating the introduction of the gel liquid into molds at different locations.

[0031] In addition, a sealing cap 304 is movably connected to the end of the bellows 303. The sealing cap 304 can seal the opening of the bellows 303, thereby keeping the bellows 303 and the inside of the storage tank 1 in a closed state. A piston rod 305 is fixedly connected to the side of the bellows 303. The piston rod 305 has a hollow structure and is interconnected with the inside of the bellows 303. The hollow piston rod 305 can extract the air inside the bellows 303, thereby creating a negative pressure state inside the bellows 303 and the stirring rack 203, which facilitates the extraction of the gel liquid from the inside of the storage tank 1.

[0032] Furthermore, a piston cylinder 306 is fitted around the piston rod 305. The piston cylinder 306 is fixedly connected to the outside of the storage tank 1. The fixed piston cylinder 306 can cooperate with the piston rod 305. When the piston rod 305 moves with the bellows 303, the piston cylinder 306 can automatically draw air from inside the bellows 303 into the piston cylinder 306. A vent hole 307 is provided at one end of the piston cylinder 306. The structure of the vent hole 307 allows the interior of the piston cylinder 306 to communicate with the external environment, thus facilitating the entry of outside air into the piston cylinder 306 through the vent hole 307 or the discharge of air from inside the piston cylinder 306 when the piston rod 305 moves inside the piston cylinder 306.

[0033] It is worth noting that a handle 308 is fixedly connected to the outer end of the bellows 303. The handle 308 allows operators to easily move or extend the bellows 303. Additionally, a heat-insulating pad is fitted over the handle 308 to prevent heat transfer and ensure it is usable by the operator. A bracket 309 is fixedly connected to the outer side of the storage tank 1, and the handle 308 is movably connected to the bracket 309. The bracket 309 allows for easy suspension of the handle 308 or the end of the bellows 303.

[0034] In addition, a drive frame 310 is fixedly connected to the side of the sleeve 208. The drive frame 310 can drive the sleeve 208, causing it to slide along the inlet pipe 207. A guide rod 311 is slidably connected to the drive frame 310. The guide rod 311 is fixedly connected to the bottom of the storage tank 1. The guide rod 311 can guide the movement of the drive frame 310. A traction rope 312 is fixedly connected to the drive frame 310. The end of the traction rope 312 is fixedly connected to the end of the bellows 303. The traction rope 312 can make the sleeve 208 and the bellows 303 cooperate with each other, so that the bellows 303 can synchronously drive the sleeve 208 to open or close when it moves.

[0035] In use, the automatic mixing device for rapid gel preparation of this utility model first adds the raw material into the storage tank 1 through the feed inlet. Then, the motor and heating coil 202 are started. The motor drives the support rod 201 to rotate continuously, while the heating coil 202 continuously heats the support rod 201, keeping it within a set temperature range. During rotation, the support rod 201 drives the stirring frame 203 to rotate continuously. The stirring blades 204 on the side of the stirring frame 203 impact the stop block 206 as the frame rotates, causing them to oscillate periodically and agitate the gel liquid inside. The heat-conducting stirring frame 203 and stirring blades 204 evenly transfer heat from the support rod 201 to the gel liquid, thus rapidly melting the gel raw material. When gel preparation is complete and molding is required, the corrugated pipe 303 is moved downwards by the handle 308, moving its opening to the mold. Then, the sealing cap 304 is opened to inject the gel liquid into the mold. During the movement of the bellows 303, the bellows 303 drives the piston rod 305 to move inside the piston cylinder 306. The piston cylinder 306 then extracts the air from inside the bellows 303. Simultaneously, as the bellows 303 extends, its internal air pressure decreases due to the volume change, causing the bellows 303 to tighten the traction rope 312 as it moves. The bellows 303, continuing to move, uses the tightened traction rope 312 to drive the drive frame 310 upwards. The drive frame 310 then moves and opens the liquid inlet 209. After the liquid inlet 209 is opened, the low pressure inside the bellows 303 draws the high-temperature gel outwards. The gel flows through the liquid inlet pipe 207 and the stirring frame 203 to the support pipe 301, and then from the support pipe 301 back into the bellows 303. At this point, after opening the sealing cap 304, the gel flows from the bellows 303 into the mold. When open, the end of the bellows 303 is lower than the bottom of the storage tank 1. The bellows 303, support tube 301, and stirring rack 203 work together to form a siphon structure, which can continuously transport the internal gel liquid outward. When it is necessary to close the bellows 303, the bellows 303 is moved upward and the handle 308 is placed on the support 309. During the upward movement of the bellows 303, the drive rack 310 moves downward accordingly, and the sleeve 208 closes the liquid inlet 209. The remaining gel liquid inside the bellows 303 flows out and can be closed by the sealing cap 304, facilitating subsequent gel liquid molding operations.
