Description

A kind of fine filter

Technical field

The utility model provides a kind of fine filter that oil refining, chemical industry, plant equipment field are used to filter.

Background technology

Before the utility model proposes, the equipment that is used for liquid filtering has the ceramic core fine filter, and the sheet frame fine filter also has filter cloth fine filter and cloth bag fine filter.

Wherein ceramic core fine filter structure is to distribute a plurality of ceramic cores are installed in the housing of fine filter, downside at the fine filter housing is provided with inlet, the upper end is provided with liquid outlet, liquid enters in the fine filter from inlet, enter into the internal pipeline of ceramic core from the outside of ceramic core, again from liquid outlet that ceramic core is connected flow out.Because ceramic core is the loose structure wall, thereby the micropore on it can play the effect of obstruction to oarse-grained material, thereby produces the effect of filtering.The filter core of this fine filter stops up easily, and is not easy to clean, and service life is short.

The sheet frame fine filter is to be constituted by sheet frame and filter cloth.In sheet frame, lay filter cloth, liquid to be filtered is injected in the sheet frame in the space on the filter cloth, and then lays filter cloth in the above, and filter cloth and liquid to be filtered exerted pressure, liquid flows out down from the sheet frame of filter cloth downside, and solid portion is retained in the filter cloth, is mainly used in the Separation of Solid and Liquid of slurries.The main shortcoming that exists is interim work, and filter efficiency is low, complex operation.

The filter cloth fine filter is that filter cloth is made funnel-form, and liquid to be filtered is injected in the funnel that is constituted, and pushes filter cloth funnel and liquid to be filtered from the side, the liquid part is flowed out down from the filter cloth funnel, and solid portion is retained in the filter cloth funnel.This filter cloth fine filter is mainly used in Separation of Solid and Liquid, also exists low, the slow-footed shortcoming of efficient.

The filter bag fine filter is with filter cloth system pouch, and liquid to be filtered injects the filter bag inner chamber, discharges from the hole of filter cloth again, and solid portion is retained in the filter bag, finishes filter process.This fine filter also exists interim operation and the low shortcoming of filter efficiency.

Summary of the invention

In order to overcome the existing low shortcoming of fine filter filter efficiency, the utility model provides a kind of fine filter.This fine filter combines filtering material with the absorption of realization variable grain and the technique effect of high efficiency filter and continuous filtration with sieve plate.

The scheme that the utility model technical solution problem is adopted is: fine filter upper body and lower body connect and compose fine filter by flange respectively; Fine filter lower body downside is provided with the fine filter bearing, and the bottom of fine filter lower body is provided with floss hole, is provided with inlet in a side of fine filter lower body, in the fine filter inner chamber filter core is installed, and the outside of fine filter wall is enclosed with heat-insulation layer; Sidepiece in the fine filter upper body is respectively equipped with liquid outlet and auxiliary the import and export; The top of filter core is provided with connector, and the fine filter sieve plate is installed on the connector, is enclosed with the absorption filtering layer in the outside of sieve plate, and its filtering layer has characterization of adsorption.

Good effect is: 1, be provided with heat-insulation layer in the fine filter periphery, can keep the temperature of filter liquide when filtering; 2, because filtering layer is wrapped on the sieve plate, can adapt to bigger filter pressure, and guarantee the balance of filtering layer, prolong the service life of filtering layer; 3, on the upper body, be provided with auxiliary the import and export, can realize that the recoil of filtering layer is cleaned, with the raising filter efficiency, and the replacing time of prolongation filtering layer; 4, use filtering layer adsorption filtration to fall varigrained impurity with characterization of adsorption.Production processes such as coked waste water decoking powder, ammonia compressor inlet off line tool impurity and liquid, industry, agricultural, medicine are carried out the filtration treatment application to material in the suitable oil refining process of the utility model fine filter.

The specific embodiment

According to shown in Figure 1, fine filter upper body 2 and lower body 1 connect and compose fine filter by flange respectively.Fine filter lower body downside is provided with fine filter bearing 9, and the bottom of fine filter lower body is provided with floss hole 8, is provided with inlet 4 in a side of fine filter lower body, and filter core 5 is installed in fine filter inner chamber 1.2, and the outside of fine filter wall 1.1 is enclosed with heat-insulation layer 1.3; Sidepiece in the fine filter upper body is respectively equipped with liquid outlet 6 and auxiliary import and export 7.

According to shown in Figure 2, the top of filter core 5 is provided with connector 5.1, and fine filter sieve plate 5.2 is installed on the connector, is enclosed with absorption filtering layer 5.3 in the outside of sieve plate.

When selecting to have the filtering layer material of characterization of adsorption, not only can realize normal filtration, but also help the absorption of medium on filtering layer, to remove varigrained impurity.

The course of work of the present utility model

Liquid to be filtered fills in the fine filter inner chamber by inlet, is subjected to the effect of flow stream pressure, and diffusing absorption filtering layer and the sieve plate by filter core of liquid flow point converges in the filter core, and flows out by liquid outlet, finishes filter process.When the non-permeate of filter core outside gathers and part when stopping up filtering layer and causing filter efficiency hang down, in filter core, inject cleaning fluid by auxiliary the import and export, clean the absorption filtering layer, and make it renewal.Non-permeate is discharged from floss hole, finishes the recoil cleaning process of fine filter.
