Detachable soft bag type filter element

Technical Field

The utility model relates to the technical field of filtration, in particular to a detachable soft bag type filter element.

Background

The melt-blown filter element is a tubular filter element which is prepared by adopting nontoxic and odorless polypropylene particles and through heating, melting, spinning, traction and receiving forming. If the raw material is mainly polypropylene, the polypropylene-based filter element can be called a PP melt-blown filter element. The PP melt-blown filter element not only has wide application in water purification, but also has outstanding chemical compatibility, and is suitable for filtering strong acid, strong alkali and organic solvents; the sewage containing capacity is strong, the service life is long, and the cost is low; belongs to high-temperature bonding fibers, and does not contain humectant, antistatic agent, adhesive and the like. The product is easy to treat after being burnt into ash, meets the requirements of the FDA food and beverage industry, and does not produce dissolved matters and released matters.

The method is widely applied to the pharmaceutical industry: prefiltering various injections, medicinal liquid and injection bottle washing water, prefiltering large transfusion and various antibiotics and Chinese medicinal injection; the food industry: filtering wine, beverage and drinking water; the electronics industry: prefiltering pure water and ultrapure water; petroleum and chemical industries: filtering various organic solvents, acids and alkali liquor, and filtering oilfield water injection.

However, the cartridge is typically required to be mounted in a stainless steel or plastic container, either single or multiple cartridge combinations. The installation space is large in volume, and the loss of the filter medium is large; when the filter element is plugged and replaced, the filter container is required to be opened, and filter media are easy to drip and pollute the environment in the replacing process.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all embodiments of the utility model.

In the description of the present utility model, it should be noted that, unless explicitly specified and limited otherwise, the terms "connected," "connected," and "connected" are to be construed broadly, and may be either fixedly connected, detachably connected, or integrally connected, for example; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium. The specific meaning of the above terms in the present utility model will be understood in specific cases by those of ordinary skill in the art.

Referring to fig. 1, in a preferred embodiment of the present utility model, a removable soft capsule type filter element includes a capsule type housing 5, a top cover 6 is detachably connected to the top of the housing 5, and an exhaust assembly is disposed on the top cover 6; the bottom of the shell 5 is detachably connected with an inlet end cover 2, the inlet end cover 2 is respectively provided with a feed inlet 10 and a discharge outlet 11, the shell 5 is internally provided with a core body 4, the liquid outlet channel communicated with the discharge port 11 is arranged in the core body 4, so that the integrated design of the filter element is realized, the disassembly and the assembly are convenient, and no leakage is generated in the disassembly process. The utility model adopts soft bag type design, has small internal dead angle and is convenient for recycling residual liquid in the filter.

As a preferred embodiment of the utility model, it may also have the following additional technical features: the feed inlet 10 and the discharge outlet 11 are respectively provided with a check ball 1, and the check balls 1 of the discharge outlet 11 are provided with ejector pins 9. Therefore, when the filter is disassembled, the feed inlet check ball of the filter is pulled out, and the feed inlet is blocked under the action of internal pressure; the ejector pin at the discharge hole is not pulled out along with the filter, the ejector pin effect disappears, the stop ball blocks the discharge hole under the pressure effect, and the inlet and the outlet are all blocked, so that residual liquid in the core body can not leak.

Because some filter media are precious, the residual liquid in the replaced filter needs to be recovered. Therefore, the soft PP transparent bag is adopted by the bag, the discharging nut 7 is opened, and residual liquid inside the filter can be discharged from the top discharging opening by extruding the bag, so that the recovery of the residual liquid of the filter is realized.

In this embodiment, a sealing ring 3 is disposed between the bottom of the housing 5 and the inlet end cap 2, and the sealing ring 3 is O-shaped. Therefore, the filter element has good sealing effect.

In this embodiment, the exhaust assembly includes a discharge nut 7, a discharge plug 8 is detachably connected to the discharge nut 7, and the discharge nut 7 is screwed to the top of the top cover 6. Therefore, when the filter is fed for the first time, the vent plug is required to be opened until the medium overflows from the vent, and the plug is screwed after the venting is finished.

In this embodiment, the pouch-type housing 5 is a PP soft pouch; and the core 4 is a PP core. Therefore, the filter element is made of corrosion-resistant materials, has chemical compatibility, and can be filtered by strong acid, strong alkali and organic solvents.

The working principle of the utility model is as follows: when the filter works, a medium enters from the feed inlet 10, and the medium pushing-open check ball 1 enters the outer side of the soft bag filter element body 4; under the action of pressure, the large particles enter the central channel through the core 4, and the large particles cannot pass through the core and remain outside the core; the filter medium flows out from the central hole to the discharge hole 11, the check ball of the discharge hole 11 is jacked by the thimble 9, and the discharge hole 11 is always in an open state.

The soft bag type filter element adopted by the application is pre-installed in the soft bag, the inlet and the outlet of the filter are provided with the check balls which can move up and down, and residual liquid does not leak when the filter element is disassembled; the bag adopts soft PP transparent bag, and the raffinate in the dismantled filter bag can be discharged from the exhaust port through squeezing the bag, so that the loss of the filter medium is minimized.

The above additional technical features can be freely combined and superimposed by a person skilled in the art without conflict.

It will be understood that the utility model has been described in terms of several embodiments, and that various changes and equivalents may be made to these features and embodiments by those skilled in the art without departing from the spirit and scope of the utility model.
