Description

Cartridge filter

Technical field

The utility model belongs to cleaning filtration art, and in particular to a kind of cartridge filter.

Background technology

Cartridge filter is also known as accurate filter, is generally located on before pressure vessel, to remove the thin of 1 degree of turbidity or more Little particulate, to meet requirement of the subsequent handling to water inlet；Sometimes it is also disposed at the end of entire water treatment system, is prevented tiny micro- Grain（Such as broken resin）Into product water.After existing cartridge filter long-time use, it is easy to make between upper cover and cylinder At loosening, and filter overall weight is larger, relatively not portable enough.

Utility model content

In order to solve the deficiencies in the prior art, the utility model provides a kind of cartridge filter.

The purpose of this utility model is achieved through the following technical solutions：

Cartridge filter, including a cylinder and the filter assemblies that are set in cylinder pass through hanging ring spiral shell above the cylinder Silk is connected with upper cover, and the lower part of the cylinder is provided with import and outlet, and the filter assemblies are made of at least four filter cores, institute It is polypropylene that cylinder, which is stated, with upper cover material.

Preferably, it is provided with sealing ring between the upper cover and the cylinder.

Preferably, the import is respectively arranged at the both sides of cylinder with outlet.

Preferably, there are six the hanging ring screw settings.

Preferably, it there are five the filter core settings, and is uniformly distributed along cylinder inner ring interval.

Preferably, the import is arranged with interconnecting piece respectively in outlet, and the interconnecting piece is all made of with inlet and outlet It is threadedly coupled.

Preferably, the cylinder body bottom indent setting.

Preferably, the filter core upper end is provided with connector, and the connector is connect with filter core welding, and the connector is logical Compression bar is crossed to connect with cylinder.

The beneficial effects of the utility model are embodied in：It is connected by the hanging ring screw of upper cover and cylinder, enhances connection Stability, meanwhile, upper cover is all made of polypropylene material with cylinder so that filter more lightweight, portability and heat resistance have It is improved.

Description of the drawings

Specific implementation mode

It is specifically described the technical solution of the utility model with reference to embodiments, the utility model discloses a kind of ensured public security Filter, as shown in Figure 1, including a cylinder 1 and the filter assemblies being set in cylinder 1, the filter assemblies are by least four filters Core 4 is constituted, and in order to which more efficient is filtered, there are five the settings of the filter core 4, and is uniformly distributed along cylinder inner ring interval.When So, other quantity can also be used, but due to cartridge filter small volume itself, if setting quantity is too many, influenced instead Filter efficiency.The compression between cylinder is carried out by compression bar 5 between the filter core.Specifically, being provided with connection above the filter core Part, the connector are connect with filter core welding, the connector centrally through being connected and fixed in compression bar 5 and cylinder.With it is existing Technology Binder Phase ratio, leakproofness higher, and bearing capacity is also improved, stability and intensity higher.The material of the filter core Matter and structure type are not limited herein, can be melt-blown filter, foldable filter element etc..

In order to enhance the stability of connection, 1 top of the cylinder is connected with upper cover 2 by six hanging ring screws 8, and passes through Sealing ring 3 between upper cover 2 and cylinder 1 carries out the guarantee of further leakproofness.The both sides setting point of the lower part of the cylinder 1 There are not import 6 and outlet 7, meanwhile, the cylinder is polypropylene with upper cover material, and polypropylene material is compared to present certain mistakes Filter is greatly mitigated using the filter ratio of metal material in weight.For existing polyvinyl chloride material, gather Propylene material has the characteristics that heat safe.The import is preferably docked not with interconnecting piece is equipped with by thread bush in outlet With the pipeline of size.1 bottom indent setting of the cylinder, can carry out being placed directly in horizontal plane, the indent bottom and cylinder It is bolted between body, entire filter assembling is quick and convenient, and portability is high.

The cleaner liquid channel of the filter core is set to bottom, and the cleaner liquid channel of each filter core communicates, and joins with outlet It is logical.When filtering, material to be filtered enters from import, is flowed to and is exported by the cleaner liquid channel of bottom after filter element filtering, and It is flowed out from outlet.

Still there are many specific embodiments for certain the utility model, are just not listed one by one herein.It is all to use equivalent replacement Or equivalent transformation and all technical solutions for being formed, within the scope of all falling within the requires of the utility model protection.
