Description
Technical Field
The invention belongs to the technical field of filter processing, and particularly relates to a production process of a three-pressure-hole drought filter.
Background
The price of the traditional three-way pipe adopts the lead filling extrusion flow as follows: blanking → filling medium lead metal in the straight-through pipe → cold extrusion → annealing → mechanical forming → removing the filler lead metal → acid cleaning → drying → packaging. In the extrusion process, when the lead metal is filled and removed, a manual operation machine is adopted for processing, and production staff have a lot of contact with the lead metal.
Lead vapor can escape to form lead smoke when the lead is heated to 400-500 ℃, air is polluted, and lead pollution is formed when lead smoke dust in the air reaches a certain concentration. However, the harm of lead pollution to human body is mainly carcinogenesis and gene mutation of human body. Lead enters human body through food and respiratory routes, causes acute or chronic toxic effects of digestive, nervous, respiratory and immune systems, usually causes symptoms such as intestinal colic, anemia and muscle paralysis, and can cause encephalopathy and even death in severe cases;
the traditional three-pressure-hole drought filter takes a three-way pipe as a main body structure to form the filter, firstly, lead needs to be filled to extrude the three-way pipe, and then, a filter medium is filled, so that the production process is complicated, and the production cost is high.

The technical scheme adopted by the invention is as follows:
a production process of a three-pressure-hole drought filter comprises the following steps:
the method comprises the following steps: selecting a proper straight-through pipe;
step two: filling a filter medium into the inner cavity of the through pipe;
step three: performing cold extrusion on the straight-through pipe filled with the filter medium to preliminarily form a T-shaped two-way pipe;
step four: supplementing a filter medium into the T-shaped two-way pipe;
step five: extruding the T-shaped two-way pipe into a three-way pipe;
step six: and packaging the filter medium in the three-way pipe.
When the wall thickness of the formed T-shaped two-way pipe is not uniform, the elongation at the extrusion extension part is lengthened by 30 microns; if too much filter medium is accumulated in the formed T-shaped two-way pipe, the chamfer angle of the extending part of the T-shaped two-way pipe is repaired to be 2.5 mm-2.8 mm.
Wherein the filter media is a dry media.
Wherein the drying medium comprises activated carbon powder.
Wherein the drying medium further comprises soda lime powder.
Wherein the drying medium further comprises a molecular sieve desiccant.
And step six, adopting a connecting pipe head for packaging, wherein the connecting pipe head is in threaded connection with the three-way pipe, air holes are uniformly formed in the connecting pipe head, and a sealing cover is sleeved on the connecting pipe head.
In summary, due to the adoption of the technical scheme, the invention has the beneficial effects that:
1. the invention creatively adopts the dry medium of the non-metal powder as the extrusion medium in the three-way pipe forming process, replaces the extrusion medium of lead heavy metal in the prior art, simultaneously does not harm the health of production personnel and the problem of environmental pollution, has better practical effect than the extrusion medium of the lead metal, completes more precise bending working procedure, and can ensure that the bending position of the three-way pipe is smoother.
2. In the three-way pipe forming process, the filter medium plays a role of extruding the medium and is used as the filter medium of the three-pressure-hole drought filter, so that the production procedure of the three-pressure-hole drought filter is simplified, and the production cost of the three-pressure-hole drought filter is reduced.
3. In the invention, a drying medium is selected as a filter medium to prepare a drying filter; the drying medium comprises activated carbon powder, soda lime powder and a molecular sieve drying agent, has good extrusion characteristic and drying characteristic, and meets the production requirement.
4. When the wall thickness of the formed T-shaped two-way pipe is not uniform, the elongation at the extrusion extension part is lengthened by 30 microns; if too much filter medium is accumulated in the formed T-shaped two-way pipe, the chamfer angle of the extending part of the T-shaped two-way pipe is restored to 2.5-2.8 mm, the forming quality of the three-way pipe is further ensured, and the production quality of the three-pressure hole drought filter is further ensured.
