[0002] Sodium cellulose, usually referring to sodium carboxymethyl cellulose, is a water-soluble polymer compound obtained by chemical modification of cellulose. It belongs to the ionic cellulose ether class and combines the skeletal structure of natural cellulose with the hydrophilic groups introduced by chemical modification. Therefore, it has unique physicochemical properties and a wide range of applications. In the food industry, it is used as a thickener, stabilizer, and emulsifier in beverages, ice cream, jams, instant noodles, etc., to improve taste and texture and extend shelf life. In the pharmaceutical field, it is used as a pharmaceutical excipient in tablet binders, suspension aids, ointment bases, etc., such as increasing viscosity in oral liquids to delay drug release and improving spreadability in ointments.

[0003] The alcohol washing of sodium cellulose is a key step in its production or purification process, mainly used to remove impurities, adjust the degree of substitution, and control product performance. After alcohol washing, sodium cellulose needs to be dried by hot air. When using existing drying equipment, the feeding structure is relatively simple, which makes it easy for large particles of material to be mixed in, resulting in poor drying uniformity and reducing practicality. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hot air drying device for sodium cellulose after alcohol washing with multiple exhaust vents, comprising a drying shell, a feeding pipe fixedly connected to its upper surface, a feeding opening fixedly connected to one end of the upper surface of the feeding pipe, a guiding opening between the feeding pipe and the drying shell, a discharge pipe fixedly connected to the lower surface of the drying shell, a filter screen fixedly connected to the inner wall of the upper cavity of the drying shell, a drive motor fixedly connected to the upper surface of the feeding pipe, a transmission gear provided on the inner wall of the cavity of the feeding pipe, and a linkage gear provided on the side of the transmission gear, a guiding spiral shaft fixedly connected to one end of the shaft of the linkage gear, a transmission cylinder installed on the top surface of the cavity of the drying shell, a primary crushing blade fixedly connected to the upper outer surface of the transmission cylinder, and a stirring and turning mechanism provided on the lower outer surface of the transmission cylinder, which drives the stirring support column and mixing claw to rotate to stir the raw material, while the rotation of the turning blades turns the raw material at the lower end.

[0006] Preferably, the upper cavity inner wall of the drying shell is cylindrical, the lower cavity inner wall of the drying shell is inclined, an exhaust pipe is vertically provided on the rear surface of the drying shell, and the filter frame is disc-shaped.

[0007] By adopting the above technical solution, the cylindrical inner wall has no sharp edges, which can cooperate with the transmission cylinder and its primary crushing blade, stirring and turning mechanism and other components to operate more smoothly, reduce the resistance and retention of raw materials during the rotation and stirring process, and allow the raw materials to be crushed and stirred more evenly in this area.

[0008] Preferably, the output end of the drive motor passes through the upper surface of the feed pipe, the output end of the drive motor is fixedly connected to the upper end of the transmission gear shaft, and the transmission gear and the feed pipe are rotatably connected.

[0009] By adopting the above technical solution, this connection method can ensure that the power of the drive motor is transmitted to the transmission gear stably and efficiently, reduce power loss, and ensure that the transmission gear can rotate stably according to the speed of the drive motor, providing a reliable power source for the subsequent meshing transmission of the transmission gear and the linkage gear, as well as the rotation of the transmission cylinder.

[0010] Preferably, the linkage gear and the guide screw shaft are rotatably connected to the feed pipe, the linkage gear is meshed with the transmission gear, the transmission cylinder is rotatably connected to the drying shell, and the upper end of the transmission cylinder is fixedly connected to the lower end of the transmission gear shaft.

[0011] By adopting the above technical solution, the linkage gear and the guide screw shaft can rotate freely in the feed pipe, so that the guide screw shaft can smoothly transport the raw material from the feed opening to the guide opening, avoid raw material blockage, and ensure the continuity of the feeding process.

[0012] Preferably, the stirring and turning mechanism includes a stirring support column, which is fixedly connected to the outer surface of the lower end of the transmission cylinder, and turning blades are fixedly connected to the outer surface of the lower end of the transmission cylinder.

[0013] Using the above technical solution, the stirring and turning mechanism consists of a stirring support column and turning blades, both of which are connected to the transmission cylinder. This structural design allows the transmission cylinder to drive the stirring support column and turning blades to work simultaneously when it rotates.

[0014] Preferably, the stirring support column is arranged perpendicularly to the transmission cylinder, and a mixing claw is fixedly connected to the outer surface of the stirring support column. The mixing claw is designed to be inclined.

[0015] By adopting the above technical solution, this setting method can increase the stirring range of the stirring support column in the horizontal direction, so that the raw materials in different positions inside the drying shell can be stirred, thereby improving the comprehensiveness of stirring.

[0016] Preferably, the turning blades are spiral-shaped, and the width of the turning blades decreases from top to bottom.

[0017] Using the above technical solution, the spiral turning blades can push the raw material at the bottom upwards while guiding the raw material at the top downwards when rotating, forming a circular turning of the raw material, so that the raw material is fully mixed and turned in the drying shell, and the raw material is prevented from stagnating at the bottom.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the multi-outlet hot air drying equipment for sodium cellulose after alcohol washing:

[0019] 1. The primary crushing blade breaks down large particles of raw material. Combined with the synergistic action of the stirring support column, mixing claw and turning blade of the stirring and turning mechanism, the sodium cellulose raw material is fully turned over, avoiding local accumulation and ensuring uniform contact with hot air, resulting in better drying effect. The exhaust efficiency is increased by the vertically arranged exhaust pipes on the rear surface.

[0020] 2. The guide screw shaft ensures stable material transport. The inclined inner wall at the lower end of the drying shell cooperates with the spiral turning blades to accelerate the flow of dried material to the discharge pipe, reduce stagnation, and improve the overall processing continuity.

[0021] 3. The filter frame intercepts impurities, and the drive motor synchronously drives the operation of each component through gear transmission. The structure is compact and the power transmission is efficient, reducing failures and improving the practicality and service life of the equipment. Attached Figure Description
