Detailed Implementation

[0022] 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.

[0023] Please see Figure 1-5 This utility model provides a technical solution: a device for preparing small samples of hemodialysis membrane spinning solution, comprising: a mounting frame 1, a double-layer glass reactor 2 installed inside the mounting frame 1, an installation port 201 opened at the top of the double-layer glass reactor 2, a heating wire 202 installed in the interlayer of the double-layer glass reactor 2, an installation rod 3 installed at the top of the mounting frame 1, a closed shell 4 installed at the top of the installation port 201, a stirring assembly 8 provided at the top of the double-layer glass reactor 2, a feed inlet 14 opened at the top of the mounting frame 1, and casters 15 installed at the bottom of the mounting frame 1.

[0024] Specifically: When the device is first used, the casters 15 installed at the bottom of the mounting frame 1 make it easier to move the device. The feed port 14 opened at the top of the double-layer glass reactor 2 is used for feeding. The stirring component 8 can be started to stir the material inside the device. The heating wire 202 installed inside the jacket of the double-layer glass reactor 2 makes the heat more evenly transferred to the material inside the double-layer glass reactor 2, making the device more perfect.

[0025] In one embodiment, a serpentine condenser 5 is mounted on the surface of the mounting rod 3, a reflux distributor 6 is mounted at the bottom of the serpentine condenser 5, a hose 7 is mounted on the surface of the reflux distributor 6, and the other end of the hose 7 is mounted on the surface of the enclosed shell 4.

[0026] Specifically: A reflux separator 6 is installed at the bottom of the serpentine condenser 5 mounted on the surface of the mounting rod 3. The reflux separator 6 is connected to the closed shell 4 through a hose 7. The serpentine condenser 5 cools the high-temperature gaseous substance, causing it to condense into a liquid state. The reflux separator 6 then separates the liquid, making the device more complete.

[0027] In one embodiment, the stirring assembly 8 includes a motor 801, a rotating rod 802 is mounted on the output end of the motor 801, a cylinder 10 is mounted on the bottom of the rotating rod 802, a stirring blade assembly 11 is mounted on the bottom of the cylinder 10, a cylinder 2 12 is mounted on the bottom of the stirring blade assembly 11, and a stirring blade assembly 2 13 is mounted on the bottom of the cylinder 2 12.

[0028] Specifically: By starting the motor 801, the rotating rod 802 is driven, causing the stirring blade assembly 11 mounted on the bottom of the cylinder 10 at the bottom of the rotating rod 802 to rotate. This causes the stirring blade assembly 13 mounted on the bottom of the cylinder 12 at the bottom of the stirring blade assembly 11 to rotate as well. The stirring blade assembly 11 and the stirring blade assembly 13 stir the materials inside the double-layered glass reactor 2. By starting the cylinder 10 and the cylinder 12, the stirring blade assembly 11 and the stirring blade assembly 13 can be adjusted in height. During use, the position of the stirring blade assembly 11 and the stirring blade assembly 13 can be adjusted according to the stirring requirements, so that the device can better stir the materials and make the device more perfect.

[0029] In one embodiment, a fixing rod 9 is mounted on the surface of the mounting rod 3, and the other end of the fixing rod 9 is mounted on the surface of the motor 801.

[0030] Specifically: The motor 801 is mounted on the fixing rod 9 on the surface of the mounting rod 3. The fixing rod 9 supports the motor 801, so that the stirring component 8 can stir stably, making the device more complete.

[0031] In one embodiment, the stirring blade assembly 11 includes a mounting block 1101. The top of the mounting block 1101 is mounted on the bottom of the cylinder 10. Stirring blades 1102 are evenly spaced around the surface of the mounting block 1101. A groove 1103 is formed inside the stirring blade 1102. A cylinder 3 1104 is mounted on the inner wall of the groove 1103. A stirring blade 2 1105 is mounted on the other end of the cylinder 3 1104. The surface of the stirring blade 2 1105 is embedded in the inner wall of the groove 1103.

[0032] Specifically: When the device is in use, the cylinder 3 1104 installed on the inner wall of the groove 1103 drives the stirring blade 2 1105 to move, causing the stirring blade 2 1105 to extend from the inner wall of the groove 1103, thus unfolding the cylinder 3 1104 and the stirring blade 2 1105 for better mixing of materials. The cylinder 3 1104 is then activated to drive the stirring blade 2 1105 to retract into the inner wall of the groove 1103, allowing the stirring blade assembly 11 to be removed through the mounting port 201 at the top of the double-layered glass reactor 2, making the device more complete.

[0033] In one embodiment, the stirring blade assembly 2 13 includes a mounting block 2 1301. The top of the mounting block 2 1301 is mounted on the bottom of the cylinder 2 12. Stirring blades 3 1302 are mounted at equal intervals around the surface of the mounting block 2 1301. A groove 2 1303 is formed inside the stirring blades 3 1302. A cylinder 4 1304 is mounted on the inner wall of the groove 2 1303. A stirring blade 4 1305 is mounted on the other end of the cylinder 4 1304. The surface of the stirring blade 4 1305 is embedded in the inner wall of the groove 2 1303.

[0034] Specifically: When the device is in use, the cylinder 1304 installed on the inner wall of the second groove 1303 drives the stirring blade 1305 to move, causing the stirring blade 1305 to extend from the inner wall of the second groove 1303, so that the stirring blade 1302 and the stirring blade 1305 can be unfolded, which can better stir the material. The cylinder 1304 is activated to drive the stirring blade 1305 to retract into the inner wall of the second groove 1303, so that the stirring blade assembly 13 can be taken out through the installation port 201 opened at the top of the double-layer glass reactor 2, making the device more complete.

[0035] Working Principle: When the device is first used, it is moved to the required position through the inlet 14 at the bottom of the mounting frame 1. Then, the material is fed into the double-layered glass reactor 2 through the inlet 14 at the top of the mounting frame 1. The motor 801 is started, driving the rotating rod 802, which causes the stirring blade assembly 11 at the bottom of the cylinder 10 at the bottom of the rotating rod 802 to rotate. This causes the stirring blade assembly 13 at the bottom of the cylinder 12 at the bottom of the stirring blade assembly 11 to rotate as well. The stirring blade assembly 11 and stirring blade assembly 13 stir the material. By starting the cylinders 10 and 12, the stirring blade assembly 11 and stirring blade assembly 13 can be raised and lowered, allowing the device to adjust their positions according to the stirring requirements during use, thus enabling better stirring. The device is designed to agitate materials, thus improving its functionality. During operation, the cylinder 3 (1104) mounted on the inner wall of groove 1103 drives the agitator blade 2 (1105) to extend from the inner wall of groove 1103. Similarly, the cylinder 4 (1304) mounted on the inner wall of groove 2 (1303) drives the agitator blade 4 (1305) to extend from the inner wall of groove 2 (1303), resulting in better agitation of materials. After use, the cylinder 3 (1104) retracts the agitator blade 2 (1105) back into the inner wall of groove 1103, and the cylinder 4 (1304) retracts the agitator blade 4 (1305) back into the inner wall of groove 2 (1303). This allows the agitator blade assembly 11 and agitator blade assembly 23 to be removed through the mounting port 201 at the top of the double-layered glass reactor 2, further enhancing the device's functionality.

[0036] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way.
