Abstract
The utility model relates to a high precision quick oxygen filter, which belongs to the design and manufacture technology of a filter. The high precision quick oxygen filter is composed of a tank body, a filtration device and a control system, wherein, the tank body is divided into an upper cavity body and a lower cavity body by a partition board; the lower cavity is provided with a filter screen bucket; the upper cavity body is provided with a plurality of filtration columns; the filtration columns are helical line gap type structures which are formed by that triangular threads are winded on a skeleton with a plurality of arrises. The control system is characterized in that an outlet position is provided with a platinum resistance thermometer device can control a quick-opening valve. The utility model has the advantages of reasonable structure, colossal filtration area and filtration space, high filtration precision, high safety and automatic control, and can be used for gas filtration, metallurgy, chemical industry oxygen manufacture and the enterprises of needing oxygen.
Description
The utility model belongs to the design and the manufacturing technology field of filter, refers in particular to the filter that is used for gas filtration.
At present, the oxygen filter of common use is to be made of tank body, filter and control system.Filter adopts screen pack or boring net to filter, and limited by screen distance, and filtering accuracy is low; The backwash required time is long, influences efficiency of oxygen supply, can not substantially improve oxygen supply condition and guarantee to use oxygen safety.
The purpose of this utility model is to strengthen filter area, accelerates the rate of filtration, improves filtering accuracy, and security reliability is strong, realizes the quick oxygen filter of high accuracy of control automatically.
The purpose of this utility model is achieved in that by tank body, filter and control system and constitutes.Tank body is divided into upper and lower cavity by dividing plate, and the hole that is communicated with Filter column is arranged on the dividing plate.Filter is the screen pack bucket in lower chamber.Filter is a plurality of Filter columns that are fixed on the supporting plate in upper cavity, Filter column is the spiral form structure that is entwined by certain interval on many ribs skeleton by delta wire.Control system is for being provided with the platinum resistance thermometer sensor, device at the filter outlet place, platinum resistance thermometer sensor, device control quck-opening valve is equipped with Pressure gauge and numeral shows the differential pressure device, monitoring automatically.
During work, lower chamber is the dirty air cavity of filtered, after the oxygen of filtered enters dirty air cavity, and the hurried expansion of volume, coarse granule impurity is by deadweight settling tank bottom.After once filtering, enter Filter column by hole on the dividing plate between cavity of resorption and the epicoele, carry out essence and filter, filter back cleaning oxygen and enter in the upper cavity, enter pipe network by the upper cavity inner outlet again or to oxygen use point.
The utility model technical performance is:

Backwash flow: 45～60Nm
3/ time .max
The utility model has the advantages that, adopt upper and lower cavity, filter space is increased, big solid particle polluter in the oxygen, the space that abundant sedimentation is arranged, this will provide the optimum filtration condition to filtering microparticle impurity usefulness, Filter column be prolonged filter service time.A plurality of Filter columns filter, and filter area increases by 2～5 times.Filter column adopts accurate spiral edge type structure, and its adjacent two one metal wire gaps can be made into any precision of requirement, make the solid particle in the oxygen gas be less than 6 μ m.Filter column has the V-type separation angle, during filtration, impurity in the gas is built up and is stored in V-type, get clogged 70% when above when filtering surface is long-pending, begin to form pressure differential, backwash impurity is being subjected under the very little backwash gas external force, can the impurity that accumulate in the V-type district axially be got rid of outside the filter by Filter column.Super large filter area and filter space make its pressure loss have only 0.02～0.03MPa, more can improve service efficiency effectively.Source of the gas can uninterruptedly be provided continuously, super large filter area and filter space are arranged, add one jar and realize double-filtration, and do not need frequent backwash, can guarantee that filter is in normal operating conditions for a long time, increase work efficiency, save the energy, and can provide continuous uninterrupted to filter 100% cleaning oxygen.Dress platinum resistance thermometer sensor, device, in case during oxygen generation tempering pyrophoricity accident, the platinum resistance thermometer sensor, device can send signal, moment is opened quck-opening valve, and the gas of burning is entered among the atmosphere.High accuracy number is housed shows the differential pressure device, the pressure that can monitor upper and lower cavity automatically changes, when upper and lower cavity internal pressure difference is increased to when presetting numerical value, promptly start backwash mechanism and enter the backwash state, when upper and lower cavity pressure restores balance, enter normal operating conditions by the backwash state again, flow of backwash only is to filter 0.5% of total flow, realizes working automatically.This filter adopts the fire proofing manufacturing fully, and tank body all adopts the OCr18Ni9Ti stainless steel, all adopts HSi80～3 silizin in jar.According to wall effect " principle, add spiral edge type filtration, realize power conversion, have a fire retardation qualitatively.
