Description
Technical Field
The utility model relates to a pure water filter core that uses in pure water preparation for experiments in research analysis and production life field.
Background
The pure water filter core of present pure water system is fixed mode: the internal filler in the pure water filter element is respectively filled with one or more of substances such as activated carbon, softening agent, PP cotton core, ion exchange resin and the like according to different uses. The pure water filter element with the filling material is processed by fixing and reinforcing processes such as welding and the like when leaving a factory, and the material required for filling the interior of the pure water filter element is fixed therein and can not be detached and replaced. The user uses up this kind of fixed pure water filter core disposable abandons, and this kind of consumptive material disposable can not recycle, and extravagant big and usage is single, is unfavorable for the environmental protection.
SUMMERY OF THE UTILITY MODEL
This novel aim at: designing a purification filter element with freely replaceable filler; the purification filter element is more convenient to use, more environment-friendly and wider in application.
This novel adoption is as follows knot and is enough to realize above-mentioned purpose: the utility model provides a can freely change pure water filter core of filler which characterized in that: the pure water filter core includes the base, the cylinder, and inside packs, wherein is equipped with the internal thread on the base, and the cylinder is hollow structure, and there are water inlet and delivery port the cylinder end far away from the base, is provided with hollow well core rod in the cylinder, and well core rod one end is fixed in the water inlet end of cylinder, and in the cylinder was arranged in to the other end, be equipped with on the cylinder with the base internal thread matched with external screw thread, inside packs arrange the cylinder in, is equipped with seal structure in base and cylinder junction.
The upper and lower parts of the screw thread for fixing the cylinder and the base are sealed by rubber sealing rings, the sealing ring at the upper part is in a ring shape, and the sealing ring at the lower part is in a ring shape with a groove.
The outer side of the fixed connection part of the column body and the base is provided with a fastener.
The fastener is the stainless steel staple bolt of high strength.
The pure water filter element with the freely replaceable filler has the following advantages: 1. when the filler is replaced by the pure water filter element, the cylinder and the base are not discarded, the filler in the pure water filter element is directly replaced, the waste of the shell is effectively reduced, the cost is saved, the pollution is reduced, and the environment is protected. 2. The pure water filter core can be as required with inside filler change for the filler of needs, like: can change for hypochlorous acid or citric acid, wash pipeline and reverse osmosis membrane through hypochlorous acid or citric acid, increase application scope. This pure water filter core base is the spiral mouth, and the cylinder passes through the screw thread to be fixed with the base, strengthens fixedly through the stainless steel staple bolt in cylinder and base junction.

Detailed Description
This novel shown pure water filter core that can freely change filler, its characterized in that pure water filter core base 2 and cylinder 1 are the disconnect-type structure, and both are fixed through the screw thread.
The utility model provides a can freely change pure water filter core of filler, including base 2, cylinder 1, inside packing 9, wherein be equipped with internal thread 21 on the base 2, cylinder 1 is hollow structure, 2 ends of base are kept away from to cylinder 1 has water inlet 5 and delivery port 6, be provided with well core rod 15 in the cylinder 1, be equipped with the centre bore 8 that link up in the well core rod 15, well core rod 15 one end is fixed in 5 ends of water inlet of cylinder 1, in cylinder 1 is arranged in to the other end, be equipped with on the cylinder 1 with base 2 internal thread 21 matched with external screw thread 11, inside packing 9 is arranged in cylinder 1, be equipped with seal structure in base 2 and the 1.
The upper and lower threads fixed on the column body 1 and the base 2 are sealed by rubber sealing rings, the upper sealing ring 31 is circular, and the lower sealing ring 32 is circular with a groove.
The outer side of the fixed connection part of the column body 1 and the base 2 is provided with a fastener.
The fastener is stainless steel staple bolt 4 of high strength.
The stainless steel hoop 4 surrounds the outer circle of the joint of the base and the column body to tightly connect and fix the base and the column body.
The column body 1 and the base 2 of the pure water filter element are made of PP materials made of cleaning materials, and the PP materials are polypropylene, so that the dissolution pollution of main materials in the preparation of pure water is avoided. Compared with other materials, the PP has the characteristics of small density, good strength and the like, and the column body made of the material has the characteristic of high wear resistance and is suitable for frequent replacement and use. For better sealing, we use a triple seal: the column is an external thread 11 and the base is an internal thread 21. The cylinder and the base are connected through threads, and a first heavy sealing effect is achieved. The upper and lower threads fixedly connected with the cylinder and the base are sealed by rubber rings as shown in figure 2, the upper sealing ring 31 is circular, and the lower sealing ring 32 is circular with a groove, so that the deformation of the PP material in a high-pressure state is prevented, and a second sealing effect is achieved. The outside of the joint of the base and the column body is further reinforced by an additional high-strength stainless steel hoop 4, so that a third sealing effect is achieved. Ensure that the whole filter element can not leak in the using process.
The cylinder 1 of pure water filter core is hollow structure, and there is well core rod 15 inside, and pending water gets into well core rod 15 through the water inlet 5 of top, and rethread well core rod 15 flows into cylinder 1, flows out through the delivery port 6 of top after the filler purification.
The filter element for pure water is strictly tested, and the water quality of the filter element reaches 18.2M omega cm under the condition of filling ion exchange resin, so that the filter element completely meets national standard high-purity water indexes and American ASTM first-class water indexes. After the cleaning chlorine tablets are filled, the components such as the pipeline of the pure water system, the reverse osmosis membrane and the like can be disinfected and cleaned. No leakage occurs during the above use.
