The following disclosure provides many different embodiments, or examples, for implementing different aspects of the utility model.
The utility model provides a dialyser glue filling ring, includes glue filling ring body 1, glue filling ring body 1 one end has glue filling lid 2, be equipped with glue filling mouth 3 on the lateral wall of glue filling ring body 1, be equipped with boss 4 in the exit end of glue filling mouth 3, boss 4 with glue filling mouth 3's inner wall forms to glue outlet channel that glue filling lid 2 side inclines.
When the device is used, firstly, the two glue filling rings are connected with the dialyser shell 6, then, the hollow fibers are filled into the shell 6, the two ends of the hollow fibers are sealed by the glue filling covers 2, after the assembly is completed, glue filling is checked, pouring glue is injected into the shell through the glue filling nozzles 3 of the glue filling covers 2, and centrifugal treatment is carried out. And removing the glue filling cover 2 and the glue filling ring after the glue is solidified, and then carrying out subsequent processing flow.
On the research surface, the length of boss overlength probably leads to pouring sealant to spill over, is unfavorable for the normal clear of pouring sealant. In some dialyzer glue-pouring ring examples, the length of the boss 4 does not exceed 1/2 of the length of the glue-pouring nozzle 3. Thus, the pouring sealant is more favorable for flowing to the top end contacted with the hollow fiber, and simultaneously has better flow velocity in the glue pouring process.
In some examples of the glue filling ring of the dialyzer, the length of the boss 4 is 1/10 to 1/3 of the length of the glue filling nozzle 3. Thus, the glue filling effect is better.
Too large a height of the boss 4 will result in too small a glue outlet, affecting the flow of pouring sealant. In some examples of the glue-pouring ring of the dialyzer, the glue-pouring nozzle 3 is a circular pipe, and the height of the boss 4 is not more than 1/2 of the diameter of the glue-pouring nozzle 3, so that the pouring sealant can flow to the top end where the hollow fibers are contacted.
In some examples of the glue filling ring of the dialyzer, the glue filling nozzle 3 is a circular pipeline, and the height of the boss 4 is 1/8-1/3 of the diameter of the glue filling nozzle 3. This is more advantageous for the flow of potting adhesive to the tip of the hollow fiber contact, as well as a faster flow rate.
In some examples of the glue filling ring of the dialyzer, the inclination angle alpha of the glue outlet channel and the surface where the glue filling cover 2 is positioned is 30-70 degrees.
In some examples of the glue filling ring of the dialyzer, a gap or a through hole 5 is formed between the tail end of the boss 4 and the glue filling ring body 1, which is beneficial to discharging bubbles in the pouring glue solution in the centrifugal glue filling process.
The size of the gap or the through hole 5 can be correspondingly adjusted according to the viscosity, the potting speed, the content of bubbles in the potting adhesive and the like of the potting adhesive. In some examples of the dialyzer priming ring, the width of the gap 5 is 1-5 mm, and the aperture of the through hole 5 is 1-5 mm. Thus, the bubble discharge is ensured, and meanwhile, the waste caused by overflow of the potting adhesive is avoided.
In some examples of the dialyzer priming ring, the surface of the boss 4 is planar or curved. The flow speed and the flow direction of the pouring sealant can be influenced to a certain extent by changing the surface condition, so that the production requirement is met.
In some examples of the dialyzer glue-pouring ring, a curved surface with smooth transition is arranged between the boss 4 and the inner surface of the glue-pouring nozzle 3. Thus, the pouring sealant can smoothly enter the sealant outlet channel, and the resistance is reduced.
