Description

Technical Field

[0001] This utility model relates to the field of sodium alginate processing technology, specifically a grinding device for processing sodium alginate. Background Technology

[0002] Sodium alginate is a byproduct of the extraction of iodine and mannitol from brown algae such as kelp or Sargassum. Its molecule is composed of β-D-mannuronic acid (M) and α-L-guluronic acid (G) linked by (1→4) bonds. It is a natural polysaccharide with the stability, solubility, viscosity and safety required for pharmaceutical excipients. Sodium alginate has been widely used in the food industry and the pharmaceutical field.

[0003] Currently, the production and processing of sodium alginate requires grinding. Due to the large size of sodium alginate particles, a lot of time is wasted during the grinding process. In addition, the distance between the grinding rollers needs to be adjusted according to the different particle sizes required for sodium alginate, but the current equipment does not make it convenient to adjust the distance between the grinding rollers.

[0004] The existing Chinese patent with publication number CN220969285U discloses a grinding device for sodium alginate production, including a housing. The housing contains a grinding assembly for grinding sodium alginate raw materials. The grinding assembly includes a support platform fixed to the outer wall of the housing. A motor is fixedly mounted on the support platform. A grinding shaft is fixedly connected to the output end of the motor. A grinding groove is provided below the grinding shaft. A partition is provided above the grinding shaft. A cleaning scraper is provided inside the housing. A crushing auger is provided above the partition.

[0005] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: when the device adjusts the distance between the grinding tank and the grinding shaft, the fixed size of the grinding tank and the grinding shaft results in a large gap between the different points of the two during adjustment, which needs to be improved; therefore, in order to solve the above problems, a grinding device for processing sodium alginate is proposed. Utility Model Content

[0006] To overcome the shortcomings of existing technologies and solve the aforementioned technical problems, this utility model proposes a grinding device for processing sodium alginate.

The adjustment component includes several grinding grooves distributed in a ring, the grinding grooves are opened on the surface of the cylinder body, and the diameter of the several grinding grooves gradually increases clockwise. In use, sodium alginate is put into the box body through the feeding hopper, the driver drives the grinding roller to rotate and cooperate with the grinding grooves for conveying and grinding, and the driver two drives the cylinder body to rotate, which can adjust the position of grinding grooves of different sizes, so as to realize the equidistant adjustment between the grinding grooves and the grinding shaft.

[0008] Preferably, the grinding roller and the grinding groove are respectively configured as corresponding frustum shapes.

[0009] Preferably, the adjustment assembly further includes a U-shaped mounting bracket and a partition, with both ends of the cylinder rotatably connected to the mounting bracket via shafts, and the partition fixedly installed inside the housing.

[0010] Preferably, an electric push rod is fixedly connected to the top of the partition, and the drive end of the electric push rod is fixedly connected to the mounting frame. When adjusting the grinding groove, the electric push rod is operated to lower the cylinder and cause the grinding roller to exit the grinding groove, thus avoiding operational interference. After the adjustment is completed, the electric push rod extends to raise the cylinder and restore it to its original position.

[0011] Preferably, a second driver is fixedly connected to the side wall of the mounting bracket, and the driving end of the second driver is fixedly connected to the shaft of the cylinder.

[0012] Preferably, the surface of the mounting bracket has a drop opening, through which the ground sodium alginate falls onto the guide plate.

[0013] Preferably, a screening assembly is installed inside the housing and on the shaft of the grinding roller. The screening assembly includes two inclined guide plates, one above the other. A connecting rod is fixedly connected to one side of the two guide plates. The ground sodium alginate falls onto the guide plates and is screened through screening holes. The qualified sodium alginate falls onto the lower guide plate and is discharged, while the unqualified sodium alginate is discharged through the upper guide plate.

[0014] Preferably, the surface of the guide plate is provided with screening holes arranged in a matrix, and one end of the guide plate is hinged to the box body.
