Description

Technical Field

[0001] This utility model relates to the field of sodium carboxymethyl cellulose purification technology, specifically to a sodium carboxymethyl cellulose purification and separation device. Background Technology

[0002] Sodium carboxymethyl cellulose, as an important water-soluble polymer, plays an irreplaceable role in many industrial fields. It is produced by chemical modification of natural cellulose and has a variety of excellent properties such as thickening, emulsification, suspension, stabilization and water retention.

[0003] With the continuous advancement of industrial technology and the increasing market demand, the quality requirements for sodium carboxymethyl cellulose are also becoming higher and higher. High-quality sodium carboxymethyl cellulose needs to have higher purity, more stable performance, and physicochemical properties that better meet the specific application requirements. Therefore, it is necessary to purify the sodium carboxymethyl cellulose stock solution.

[0004] Currently, the purification and separation process of sodium carboxymethyl cellulose mainly includes multiple steps such as dissolution, precipitation, filtration, washing, and drying. A crucial step in the purification process is adjusting the sodium carboxymethyl cellulose solution to neutral. This is because some acidic substances may remain during the production of sodium carboxymethyl cellulose. The presence of these acidic substances not only affects the purity and quality of the product but may also adversely affect its subsequent application performance. However, in existing sodium carboxymethyl cellulose purification technologies, workers need to use sophisticated pH testing equipment, such as a pH meter, to monitor the pH of the sodium carboxymethyl cellulose solution in real time. After detecting that the solution is acidic, an appropriate amount of alkaline substance, such as sodium hydroxide solution, is manually calculated and weighed based on the solution's volume and pH. This solution is then slowly added to the sodium carboxymethyl cellulose solution while continuously stirring the solution and monitoring the pH changes with the pH meter until the solution reaches a neutral pH range. This process is inefficient.

[0005] Therefore, in order to address the above problems, the applicant needs to design a sodium carboxymethyl cellulose purification and separation device to solve the problem. Utility Model Content

[0006] The purpose of this invention is to provide a sodium carboxymethyl cellulose purification and separation device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a sodium carboxymethyl cellulose purification and separation device, comprising a base, and a support base above the base, a mixing tank fixedly mounted on the support base, and the mixing tank being provided with a feed pipe for feeding and a discharge pipe for discharging.

[0008] It also includes: a feeding mechanism disposed above the base, and the feeding mechanism is used to input acidic solution into the mixing tank. The feeding mechanism includes a buffer tank fixedly connected to the base, and a connecting pipe is connected to the buffer tank. An extension pipe is connected to the end of the connecting pipe away from the buffer tank, and a pressure pump is provided at the liquid outlet end of the extension pipe. The liquid outlet end of the pressure pump is connected to the feeding pipe, and the feeding pipe is fixedly connected to the mixing tank.

[0009] A stirring mechanism is installed on the mixing tank, and the stirring mechanism is used to stir the solution in the mixing tank.

[0010] Furthermore, the stirring mechanism includes a servo motor mounted on the mixing tank, and the output end of the servo motor extends into the mixing tank via a mechanical seal and is provided with a rotating rod. The rotating rod is provided with a mounting sleeve, and the mounting sleeve is integrally provided with a stirring blade.

[0011] With the above structural design, when in use, the servo motor is started, which drives the rotating rod to rotate. The rotation of the rotating rod drives the mounting sleeve to rotate, and the rotation of the mounting sleeve drives the stirring blade to rotate, which slowly stirs the mixed solution in the mixing tank, thereby accelerating the adjustment rate of the pH value of the sodium carboxymethyl cellulose stock solution.

[0012] Furthermore, the mixing tank is equipped with a pH monitor, which is used to monitor and display the pH value inside the mixing tank.

[0013] With the above structural design, the pH monitor can easily monitor the pH value of the mixed solution in the mixing tank in real time.

[0014] Furthermore, a reinforcing member is fixedly installed on the extended pipe, and the reinforcing member is fixedly connected to the mixing tank.

[0015] The above structural design utilizes reinforcement components to facilitate support for extended pipes, thereby improving the stability of the hybrid pipeline.

[0016] Furthermore, a bearing seat is fixedly provided on the mixing tank, and a rotary bearing is rotatably provided on the bearing seat. A connecting plate is fixedly provided on the rotary bearing, and a movable cover is provided on the connecting plate.

[0017] With the above structural design, the rotating bearing facilitates the movement of the movable cover during use, and the opening of the movable cover allows for easy observation of the solution inside the mixing tank.

[0018] Furthermore, the movable cover is threaded with a fastening screw, and the fastening screw is threadedly connected to the mixing tank.

[0019] The above structural design utilizes fastening screws to improve the tightness of the connection between the movable cover and the mixing tank, resulting in high sealing performance.

[0020] Compared with the prior art, the beneficial effects of this utility model are: the sodium carboxymethyl cellulose purification and separation device facilitates the adjustment of the pH value of the sodium carboxymethyl cellulose stock solution using alkaline solution, and has high purification efficiency, as detailed below:

[0021] In operation, the sodium carboxymethyl cellulose purification and separation device uses a feed pipe to input the sodium carboxymethyl cellulose stock solution into a mixing tank. A pH monitor is used to observe the solution. When the pH monitor indicates the solution is acidic, a pressure pump is activated. The pressure pump draws alkaline solution from the buffer tank into a connecting pipe. Under pressure, the solution in the connecting pipe flows through an extension pipe and a feed pipe into the mixing tank. With the help of a stirring mechanism, the mixed solution in the mixing tank becomes neutral, which facilitates the improvement of the purity of the sodium carboxymethyl cellulose and results in high operating efficiency.

[0022] When using this sodium carboxymethyl cellulose purification and separation device, the servo motor is started to adjust the pH value of the sodium carboxymethyl cellulose stock solution. The servo motor drives the rotating rod to rotate, which in turn drives the mounting sleeve to rotate. The rotation of the mounting sleeve drives the stirring blade to rotate, which slowly stirs the mixed solution in the mixing tank, thereby accelerating the pH adjustment rate of the sodium carboxymethyl cellulose stock solution.

[0032] With the above structural design, during use, the sodium carboxymethyl cellulose stock solution is fed into the mixing tank 11 via the feed pipe 12, and the pH monitor 14 is observed. When the pH monitor 14 shows that the solution is acidic, the pressure pump 23 is started. The pressure pump 23 draws the alkaline solution in the buffer tank 20 into the connecting pipe 21.
