Abstract
The diaphragm type micro porous aerator with over-pressure protection consists of conic pedestal, spiral gland, air homogenizing board and synthetic rubber diaphragm. The air homogenizing board is set on the conic pedestal, the synthetic rubber diaphragm with closeable hole is set on the air homogenizing board, and the spiral gland is set on the synthetic rubber diaphragm and screw connected to the upper end of the conic pedestal. There are also one connecting pipe screwed to the lower end of the conic pedestal, one lining pipe screwed to the upper end of the connecting pipe, one movable valve plate with ventilation hole below the lining pipe, and one spring set between the movable valve plate and the lining pipe, with the lining pipe and the movable valve plate being made of PTFE. The pressure of the spring on the movable valve plate may be regulated precisely with one regulating mechanism. When the pressure is too high, the movable valve plate is driven pneumatically to close the airflow passage to avoid damage of the rubber diaphragm.
Description
Technical field:
The present invention relates to water treatment device, relate in particular to sewage biochemical treatment engineering, particularly a kind of aerating apparatus, concrete is a kind of microporous diaphragm aerating apparatus with overvoltage protection.
Background technology:
Industrial sewage and city domestic sewage biochemical treatment engineerings such as in the prior art, microporous diaphragm aerator is widely used in petrochemical industry, printing and dyeing, weaving, food, brewages, pharmacy, process hides, papermaking.Microporous diaphragm aerator of the prior art is by a conical base, a spiral cover, an airflow homogenizing plate and a synthetic rubber diaphragm constitute, airflow homogenizing plate is arranged on the upper end of conical base, the synthetic rubber diaphragm is enclosed within on the airflow homogenizing plate, spiral cover be arranged on synthetic rubber diaphragm-operated upside and with the upper end of conical base by being threaded, the synthetic rubber diaphragm is fixed, on the synthetic rubber film, have 2100-2500 open and close type eyelet, the lower end of conical base connects filling channel, when disposing of sewage, air is by the gas distribution pipeline, airflow homogenizing plate, evenly enter between rubber diaphragm and the airflow homogenizing plate, under the air pressure effect, diaphragm is heaved slightly, eyelet opens, gas passes through from micropore, Xiang Shuizhong provides dissolved oxygen, to carry out biochemical treatment, when stopping air feed, because pressure descends gradually between diaphragm and the airflow homogenizing plate, make eyelet closed gradually, after pressure all disappears, because the rebound resilience effect of hydraulic pressure effect and diaphragm itself is compacted at diaphragm on the airflow homogenizing plate.Mixed solution in the aeration tank just can not produce and pour in down a chimney.But, because the synthetic rubber diaphragm can wear out gradually, when pressure is big slightly in the gas distribution pipeline, the diaphragm transition is heaved, cause eyelet to tear, influence bubble and produce.
Summary of the invention:
Technical problem of the prior art to be solved by this invention is: because microporous diaphragm aerator of the prior art is by a conical base, a spiral cover, an airflow homogenizing plate and a synthetic rubber diaphragm constitute, airflow homogenizing plate is arranged on the upper end of conical base, the synthetic rubber diaphragm is enclosed within on the airflow homogenizing plate, spiral cover be arranged on synthetic rubber diaphragm-operated upside and with the upper end of conical base by being threaded, the synthetic rubber diaphragm is fixed, on the synthetic rubber film, have 2100-2500 open and close type eyelet, the lower end of conical base connects filling channel, when disposing of sewage, air is by the gas distribution pipeline, airflow homogenizing plate, evenly enter between rubber diaphragm and the airflow homogenizing plate, under the air pressure effect, diaphragm is heaved slightly, eyelet opens, gas passes through from micropore, Xiang Shuizhong provides dissolved oxygen, to carry out biochemical treatment, when stopping air feed, because pressure descends gradually between diaphragm and the airflow homogenizing plate, make eyelet closed gradually, after pressure all disappears, because the rebound resilience effect of hydraulic pressure effect and diaphragm itself is compacted at diaphragm on the airflow homogenizing plate.Mixed solution in the aeration tank just can not produce and pour in down a chimney.But, because the synthetic rubber diaphragm can wear out gradually, when pressure is big slightly in the gas distribution pipeline, the diaphragm transition is heaved, cause eyelet to tear, influence bubble and produce.
The technical scheme that the present invention is adopted for solution above-mentioned technical problem of the prior art provides a kind of microporous diaphragm aerating apparatus with overvoltage protection; described thisly have the microporous diaphragm aerating apparatus of overvoltage protection by a conical base; a spiral cover; an airflow homogenizing plate and a synthetic rubber diaphragm constitute; described airflow homogenizing plate is arranged on the upper end of described conical base; described synthetic rubber diaphragm is enclosed within on the described airflow homogenizing plate; described spiral cover be arranged on described synthetic rubber diaphragm-operated upside and with the upper end of described conical base by being threaded; the synthetic rubber film is provided with 1000～5000 open and close type eyelets; wherein; the lower end of described conical base is provided with a pipe connecting by screw thread; the upper end of described pipe connecting is provided with an internal lining pipe by internal thread; the tube chamber of described internal lining pipe is communicated with described conical base; the below of described internal lining pipe is provided with a movable valve block; the axle center of described movable valve block is connected with a circular cone projection; at least be provided with two ventilating pits with the axle center symmetry on the described movable valve block; described ventilating pit is all in the outside of the projection of described circular cone projection; the below of described movable valve block is provided with a set collar; described set collar is fixedlyed connected with the inner chamber of described pipe connecting, is provided with a spring between described movable valve block and described internal lining pipe.
Further, be provided with rotation in the top end face of described internal lining pipe and drive projection.
Further, be provided with sealing-ring between described conical base and the described spiral cover.
Further, be carved with markings in the top end face of described internal lining pipe, be carved with markings in the upper surface of described pipe connecting.
Further, described internal lining pipe and movable valve block constitute by nylon or polytetrafluoroethylmaterial material.
Principle of work of the present invention is: before microporous diaphragm aerator was installed, according to the rated maximum pressure value of rubber diaphragm, by the rotation internal lining pipe, regulating spring was to the pressure of movable valve block.With after the gas distribution pipeline is fixedlyed connected, when inflation pressure was excessive, air pressure promotion activity valve block overcame spring pressure with pipe connecting, and the circular cone projection is closed the gas channel in the internal lining pipe, thereby prevented that overvoltage from damaging rubber diaphragm.
The present invention and prior art contrast, and its effect is actively with tangible.The present invention is provided with movable valve block in pipe connecting, by rotation regulating mechanism can meticulous adjustment spring to the pressure of movable valve block, when inflation pressure is excessive, air pressure promotion activity valve block closed gas flow passage, thereby prevent that overvoltage from damaging rubber diaphragm.
