Abstract
The utility model is a pulse backwashing filter, comprising a filter head, a backwashing portion and related pipelines. The filter head has a structure with an upper part and a lower part which are connected by flanges. On each of the two flange surfaces a stepped cylinder is disposed. Two filter screen plates are disposed in the stepped cylinder, and a filter screen with proper meshes is fixed in the two plates. The lower part structure of the filter head is actually a closed ended cylinder with a flange surface, and holes regularly arrayed on the whole back surface and side surface of the cylinder. The main part of the backwashing portion is a water tank with a proper volume, and the water tank is more than two meters above the filter head. The liquid level in the water tank is controlled by a level control valve of the water tank, and a discharge control valve is disposed on the bottom of the water tank. When the filter head needs backwashing, the discharge control valve is opened for the pulse backwashing of the filter head. The pulse backwashing filter has a simple structure, and the automatic backwashing function of the filter is realized, and the safety of sampling instrument on-line detection is improved.
Description
Technical field:
The utility model relates to liquid sample filtering technique in a kind of clean water treatment, the sewage disposal process.
Background technology:
Obtaining of each water quality parameter index in the water treatment procedure generally all need be used various instrument such as COD appearance, ammonia nitrogen appearance etc.These instrument are made up of sampling part and detection demonstration two parts usually.Sampling part extracts liquid to be measured with sampling pump usually in reaction tank, be connected to instrumentation through pipeline again and carry out work.Because these instrument require than higher sampling water very much, sampling water is easy to stop up after getting into the gauge internal pipeline, in case stop up, just causes the instrument cisco unity malfunction, and influence is produced.In order to prevent pipeline blockage, add fixed filter on the pipeline of in practical applications, being everlasting, but filter can stop up also very soon, dismounting washing and filtering device is unusual trouble again.
Summary of the invention:
Be easy to blockage problem after getting into the gauge internal pipeline to sampling water, add fixed filter on the pipeline of in practical applications, being everlasting, but filter also can stop up very soon, dismounting washing and filtering device is unusual trouble again.To this problem, design a kind of filter of pulsed backwash of can realizing and to solve the plugged filter problem.
The utility model is a kind of pulse backwashing filter.This filter is made up of filtering head and backwash part and associated pipe etc.
Filtering head is that up-down structure connects with flange, respectively designs a face of cylinder step on two flange faces, and the depth of section of step is identical with width; Two screen pack clamping plate are housed in this face of cylinder step, a fixing mesh screen pack in two clamping plate, the screen pack clamping plate are full of regularly arranged aperture; The diameter of two clamping plate is slightly less than cylinder table terrace diameter; Thickness equals or is slightly larger than the height of cylinder table terrace, and flange face is used rubber packing, and two flanges can adopt stainless steel support to clamp; Take flange bolt apart, can take out filter screen and carry out the cleaning and filtering head.Two screen pack clamping plate are full of the suitable aperture of regularly arranged diameter, and two clamping plate and filter screen are fixing as a whole through alignment pin, and the aperture of two clamping plate must align in the time of fixedly.Two alignment pin position design the edge at clamping plate as far as possible; Make it not influence current, the length of alignment pin should be shorter than the gross thickness of two clamping plate, and the substructure of filtering head is actually one flanged the round-ended cylinder that has; The wall thickness of cylinder is 5 millimeter; The height of cylinder is 15 to 20 millimeters, and cylinder bottom surface and side have the full regularly arranged aperture of row, and the aperture is 3 millimeter.
The superstructure of filtering head is actually one flanged open circles table top; Above little below big; The wall thickness of round table surface also is 5 millimeter; Back cut diameter extension with round platform is designed to and respective line connecting interface structure, and interface generally is designed to internal thread version, and the round platform diameter at butt end should be more than or equal to the top diameter twice.
Backwash part critical piece is the water tank of a suitable volume, and the height of water tank generally will be higher than filtering head more than two meters, and the liquid level that gets into water tank is controlled by the high water tank control valve; After liquid level reaches the water tank height; Control valve will be closed the liquid that gets into water tank automatically, and control valve can be that Floating Ball Liquid Level Control also can be a contact liquid level control form, at water tank bottom exhaust-control valve is installed; When filtering head needs backwash, open exhaust-control valve filtering head is carried out pulse backwashing.This control valve can be manual backwash mode or automatic backwash pattern; If manually backwash; Open hand control valve, one pulse of water formation of water tank flows downward fast and accomplishes the backwash work to filter, if the backwash of automatic control pattern; Following control valve is designed to automatically controlled or Air control valve, can carry out the automatic backwash of timing cycle property with the time interval.
The beneficial effect of the utility model:
Reasonable in design, simple in structure, realized the automatic backwash function of filter, improved the security of the online detection of sampling instrument.
Description of drawings:
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Fig. 1 is the utility model operating position sketch.
Fig. 2 is the utility model filtering head structure diagram.
Referring to Fig. 1,1 is filtering head, and 2 is sampling pump, and 3 is by-pass valve control, and 4 are the emission control valve, and 5 is water tank, and 6 is the Floating Ball Liquid Level valve, and 7 is the fluid to be measured instrumentation.
