Abstract
The utility model discloses a self-cleaning liquid filter, which comprises a filter body, a top scraping mechanism and a bottom scraping mechanism, wherein the filter body has a barrel body structure; filter plates are axially arranged in a barrel body to form two cavities; the barrel wall of the two cavities are connected with a connecting pipe respectively; the connecting pipes are taken as a water inlet pipe and a water outlet pipe of the barrel body; the water inlet pipe and the water outlet pipe are provided with control valves; the top scraping mechanism comprises a top scraper and a top cylinder; the top cylinder is arranged on a barrel body cover plate on the water inlet pipe side of the filter body; a piston rod of the top cylinder extends into the barrel body; the top scraper is connected to the end part of the piston rod, and is contacted with the inner wall of the barrel body and the filter plates; the bottom scraping mechanism comprises a bottom plate and a bottom cylinder; and the bottom plate is movably connected and hermetically matched with the bottom of the filter body, and is connected to a piston rod of the bottom cylinder. Due to the arrangement of upper and lower scrapers, a liquid filter can be cleared conveniently, the influence of frequent replacement of a filter screen on the production can be avoided, the working efficiency is improved, and the labor intensity is lowered.
Description
Technical field
The utility model relates to filter, relates in particular to a kind of self-cleaning liquid filter.
Background technology
The acid pickle that the chlorohydric acid pickling unit produces processings of need regenerating is by spray roasting generation regenerated acid and iron oxide red.For improving the quality of iron oxide red, spent acid will carry out silica removal before regeneration, its technological process is that spent acid is imported in the dissolving tower, the broken limit of spent acid and iron and steel is reacted, reacted solution is from the overflow of dissolving tank top, add the ammoniacal liquor reaction again, and feed compressed air oxidation, enter settling tank at last and precipitate desiliconization.After pickle liquor and the reaction of iron and steel slitter edge, contain a large amount of suspensions in the solution, be mainly the impurity that some are insoluble to acid solution.These solution that contain more suspension cause the obstruction of follow-up cooler, pipeline through regular meeting after the top overflow of dissolving tower, the method for generally taking at present is to install a filter screen additional at dissolving tower outlet conduit flange place, and the suspension in the solution is filtered.But because the suspension content in the dissolving tower overflowing liquid is higher, filter screen promptly need be changed in use for some time, and this moment must be with the silica removal compressor emergency shutdown, flange is pulled down changed filter screen again, and frequency of maintenance is very high, has also brought inconvenience to produced on-site.
Summary of the invention
The purpose of this utility model is to design a kind of self-cleaning liquid filter, can judge according to import, outlet fluid flow difference and stop up, and realize self-cleaning liquid filter.When the fluid flow by filter descends, can temporarily disconnected liquid in-out valve, and by the air cylinder driven scraper, the filter residue in the filter is removed.Can remove frequent replacing filter screen to the influence that production causes, increase work efficiency, reduce labour intensity.
For achieving the above object, the technical solution of the utility model is:
A kind of self-cleaning liquid filter, it comprises, filter body, it is a tube structure, forms two chambers by filter plate axially is set in the cylindrical shell, the barrel of two chambers respectively connects establishes a tube connector, as the cylindrical shell inlet tube and outlet tube; Establish a control valve on the inlet tube and outlet tube respectively; The top scraper mechanism comprises top scraper, top cylinder; The top cylinder is arranged on the cylindrical shell cover plate of filter body water inlet pipe side, and its piston rod stretches in the cylindrical shell; The top scraper is connected in the piston rod end of stretching in the cylindrical shell, and the top scraper contacts with filter plate with cylinder inboard wall, along the filter plate apparent motion; The bottom scraper mechanism comprises base plate, bottomed cylinder; Base plate flexibly connects with the filter body bottom, the airtight cooperation, and base plate is connected in the bottomed cylinder piston rod, and the filter plate cooperation in the base plate cylindrical shell is finished and struck off.
Further, the cylindrical shell chamber section configuration consistent size of described top scraper and filter body water inlet pipe is close to filter liner and filter plate.
The cover plate of described top scraper and filter body water inlet pipe side neck fluid chamber is an one.
Described control valve is magnetic valve or pneumatic operated valve.
Establish a flowmeter on the described inlet tube and outlet tube respectively.
Described bottomed cylinder piston rod stroke is no more than the filter body base diameter.
Sealing ring is established in described filter body bottom, and base plate cooperates with sealing ring is airtight.
Overflowing liquid enters filter from inlet side, by the impurity such as suspension in the filter plate filter liquide.Liquid after the filtration flows out from outlet side; By the import of the online detection inlet side of flowmeter fluid flow, export the result to programmable logic controller PLC; Export by the online oral-lateral fluid flow that detects of flowmeter, export the result to programmable logic controller PLC;
When inlet flow rate-rate of discharge＞permission difference in flow (preset value), illustrate that promptly filter stops up, need clean.This moment, PLC signaled to inlet side and outlet side control valve, cut off the import and export fluid flow; Bottomed cylinder drives bottom scraper and laterally moves, and by interlocking of scraper and filter plate, attached amassing at the filter residue of blade surface is removed.
Air cylinder driven top, top scraper moves down, and will strike off attached to the filter residue on the filter plate.The top cylinder resets, and scraper is got back to initial position; Bottomed cylinder resets, and scraper is got back to initial position; Open the outlet side control valve, open the inlet side control valve, filter resumes operation.
The beneficial effects of the utility model
The utility model can be removed liquid filter easily by lower coating blade is set, and can remove frequent replacing filter screen to the influence that production causes, and increases work efficiency, and reduces labour intensity.Can also judge obstruction, and realize automatically cleaning according to import, outlet fluid flow difference by flowmeter is set.

Fig. 2 is the cross-sectional schematic of the utility model embodiment.
Fig. 3 is the working state schematic representation of the utility model embodiment.
The specific embodiment
Referring to Fig. 1～Fig. 3, self-cleaning liquid filter of the present utility model, it comprises,
In the present embodiment, the cylindrical shell chamber 101 section configuration consistent size of described top scraper 71 and filter body water inlet pipe 3 are close to filter body 1 liner and filter plate 2.
Described top scraper 71 is an one with the cover plate of filter body water inlet pipe side cavity 101.
Establish a flowmeter 9,9 ' respectively on the described inlet tube and outlet tube 3,4.
Described bottomed cylinder piston rod stroke is no more than the filter body base diameter.
Overflowing liquid enters filter from water inlet pipe, by the impurity such as suspension in the filter plate filter liquide.Liquid after the filtration flows out from outlet pipe; Bottomed cylinder drives base plate and laterally moves, and by interlocking of scraper and filter plate, attached amassing at the filter residue on scraper (base plate) surface is removed; Air cylinder driven top, top scraper moves down, and will strike off attached to the filter residue on the filter plate.
