Description

Technical Field

[0001] The utility model relates to the technical field of sodium hyaluronate production equipment, in particular to an alcohol precipitation sodium hyaluronate precipitation device equipped with a sintered mesh. Background Art

[0002] Sodium hyaluronate (HA) is a linear high molecular weight polysaccharide. It is cross-linked with cross-linking agents such as 1,4-butanediol diglycidyl ether or divinyl sulfone under alkaline conditions to form a cross-linked sodium hyaluronate gel. The gel prepared by cross-linking not only retains the good biocompatibility of HA, but also greatly prolongs its retention time in the body. It has become the most commonly used tissue filler in clinical practice. Since the residual cross-linking agent is toxic to the human body, the unreacted free cross-linking agent must be removed after the cross-linking of sodium hyaluronate is completed.

[0039] Working principle: Before using this alcohol precipitation sodium hyaluronate precipitation device with sintered mesh, it is necessary to check the overall condition of the device to ensure that it can work normally. Figure 1 - Figure 6As shown, first, the alcohol-precipitated sodium hyaluronate liquid is poured into the precipitation tank 101 from the feed port. During the descent, the alcohol-precipitated sodium hyaluronate liquid is filtered and screened through the sintered mesh body 121 to remove some impurities. In order to avoid clogging of the sintered mesh body 121, the driving motor 103 drives the driving wheel 104 to rotate, and the meshing action between the driving wheel 104 and the first driven wheel 105 and the second driven wheel 107 is utilized to drive the first driven wheel 105 and the second driven wheel 107 to rotate simultaneously. When the first gear ring 106 is meshed with the third gear ring 109, it drives the threaded rod 110 to rotate forward, thereby utilizing the meshing action between the first gear ring 106 and the third gear ring 109. The threaded rod 110 and the threaded sleeve 115 are used to work together, and the guide rod 117 limits the threaded sleeve 115, so that the sliding sleeve 116 moves rightward on the outer side of the guide rod 117. When the sliding sleeve 116 contacts the fixed block 118, the sliding sleeve does not move, so that the threaded rod 110 moves leftward, so that the second gear ring 108 and the third gear ring 109 are engaged to drive the threaded rod 110 to reverse, thereby driving the threaded sleeve 115 to move leftward, so that the brush 120 can move left and right on the surface of the sintered mesh body 121 to clean the sintered mesh body, and at the same time, the cover cap 123 is rotated to discharge the filter residue from both ends;

[0040] Secondly, when it is necessary to extract the sediment at the bottom of the sedimentation tank 101, when the sediment is accumulated higher than one end of the second hose 204, the handle 208 is turned to drive the stopper 206 to rotate in the first T-hole 205, so that the first hose 203 is connected to the water pump 202, and the upper part of the liquid can be extracted, and the piston 219 is driven to move in the measuring cylinder 214 by the multi-stage telescopic rod 220. When the piston 219 moves to the right, the pressure in the measuring cylinder 214 is used to drive the first rubber ball 213 to compress the third spring 212 so that the discharge pipe 209 is connected to the measuring cylinder 214, so that the sediment in the sedimentation tank 101 can be sucked into the measuring cylinder 214, and at the same time, the measuring cylinder is used The pressure in 214 drives the second rubber ball 218 to move upward and stretch the fourth spring 217, so that the second connecting tube 215 is disconnected from the measuring cylinder 214, and the sediment in the second connecting tube 215 is prevented from flowing back into the measuring cylinder 214. When the piston 219 moves to the left, the pressure in the measuring cylinder 214 drives the first rubber ball 213 to move and block the discharge pipe 209 to prevent the sediment from flowing back into the sedimentation tank 101. At the same time, the pressure drives the second rubber ball 218 to move, so that the second connecting tube 215 is connected to the measuring cylinder 214, and the sediment can be discharged. By observing the scale on the measuring cylinder 214, the amount of sediment extracted each time can be known.
