Description

A kind of duplex strainer

Technical field

The utility model relates to duplex strainer technical field, in particular to a kind of duplex strainers.

Background technique

Duplex strainer be also referred to as duplex switch filtering device it be to be formed in parallel by two stainless steel filters, have structure Many advantages, such as new reasonable, good airproof performance, negotiability are strong, easy to operate has wide range of applications, adaptable multipurpose Filter plant, especially filter bag side leakage probability are small, can accurately insure that filtering accuracy, filtering is substantially without supplies consumption, so that behaviour Make cost reduction, duplex strainer uses two three-way ball valves, two monotubular filters are fitted together, when cleaning filter It need not stop, as long as being switched to another filter by three-way ball valve, guarantee its continuous work.

But it is bolted between current duplex strainer staving and upper cover, the intracorporal filter vat upper end of bucket is all logical It crosses screw to be fixed in staving, outlet tube is welded in filter vat bottom, and outlet tube passes through staving and goes out liquid by clip and external Pipeline connection, it is more troublesome when dismantling filter vat cleaning in this way, it wastes time, and sealed in the junction of outlet tube and staving It is bad, it is easy leakage, wastes raw material, pollutes ground.

Utility model content

The technical problems to be solved in the utility model is to overcome the above technological deficiency, and it is simple to provide a kind of structure, filter vat Disassembly, cleaning are convenient and efficient, preferably a kind of duplex strainer of sealing performance.

In order to solve the above technical problems, technical solution provided by the utility model are as follows: a kind of duplex strainer, including two Identical filter body, the two filter bodies inlet are connected together, and liquid outlet is connected together, and inlet is connected It is connected on pipeline with liquid outlet on pipeline and is equipped with Pneumatic three-way valve, the filter body includes sequentially connected from top to bottom Upper cover, staving and support leg, the upper cover and staving upper end border are equipped with connecting plate, and two connecting plates up and down are equipped with fast Quick-detach device, the quick-release arrangement include hanging ring, tensioning screw, two fixed plates and bolt, the tensioning screw top It is connect with hanging ring, bottom is bolted between two fixed plates, passes through quick-release arrangement between the upper cover and staving Close connection, is equipped with filter vat in the staving, and filter vat upper end border is equipped with hanging plate, the inner wall of barrel be equipped with and The corresponding support plate of hanging plate, the filter vat bottom are equipped with outlet tube, and the staving bottom is equipped with and outlet tube matches Fixing sleeve, the fixing sleeve include the pedestal for being fixed on staving bottom, the bushing being movably connected in pedestal and are connected to pedestal External briquetting is equipped with tetrafluoro packing between the bushing and pedestal.

The utility model compared with prior art the advantages of be: between upper cover and staving be equipped with quick-release arrangement, will Hanging ring is unscrewed, and hanging ring is produced from upper and lower two connecting plate with tensioning bolt, dismantles quick and easy for installation, filter vat upper end border Hanging plate, which is directly taken, to be placed in the intracorporal support plate of bucket, while filter vat bottom outlet tube lower end passes through staving and consolidated by fixing sleeve It is scheduled on outside staving, the deformation of tetrafluoro packing is squeezed by briquetting and pushes down bushing, so that being connected between outlet tube and staving firm tight Close, sealing performance is preferable, avoids outlet tube and the leakage of staving junction, while dismantling more quick.

As an improvement, the bushing is resilient bushing, one end that the briquetting is located at base exterior passes through screw and pedestal It is connected, one end bottom that the briquetting is plugged in pedestal is contacted with tetrafluoro packing, and by tightening screw, briquetting moves up extruding four Fluorine packing, tetrafluoro packing stress deformation squeeze resilient bushing, and bushing is made to be close to outlet tube outer wall, outlet tube are close-coupled at solid In fixed set, at the same tetrafluoro disk it is pure it is teflon fibre braided made of, there is good flexible adjustability and leakproofness, make Junction leakproofness between outlet tube and fixing sleeve is preferable, avoids the appearance of leakage situation.

As an improvement, being equipped with sealing ring between two connecting plates up and down, the two connecting plate outer edges up and down are provided with Groove corresponding with tensioning screw, the tensioning screw are located in groove, and gasket is equipped between the hanging ring and upper junction plate, The hanging ring rotates into or produces groove using bolt as rotation center with tensioning screw, and when tightening hanging ring, hanging ring passes through gasket pressure It lives in connecting plate to move down, makes to be completely embedded between two connecting plates up and down, tensioning screw is located in groove, can avoid staff not Carefully encounter quick-release arrangement and injured, improve the security performance of equipment, while being equipped with and sealing between upper and lower two connecting plate Circle was not only completely embedded upper and lower two connecting plates, but also can prevent extraneous dust from entering staving from gap between upper and lower two connecting plate It is interior, improve the quality of institute's filtering product.

As an improvement, being equipped with washer between the hanging plate and support plate, support plate bottom border uniform welding has plate Muscle, the filter vat is taken by upper end border hanging plate to be put on the supporting plate, is led between the outlet tube upper end and filter vat bottom Threaded connection is crossed, the outlet tube lower end is fixed on the outside of staving by fixing sleeve, and washer can play certain damping and make With avoiding between hanging plate and support plate rigid contact from wearing, extend the service life of hanging plate and support plate, hanging plate is placed directly in branch On fagging, filter vat bottom is connect by screw thread with outlet tube, and the filter vat convenient disassembly made is quick, improves working efficiency.

As an improvement, the upper lid is equipped with water inlet and automatic exhaust steam valve, the staving bottom is welded with sewage draining exit, into The mouth of a river can send water to idle side filter, be rinsed to the intracorporal filter vat of bucket, the sewage after cleaning passes through row The gas generated in filter process can be automatically drained out by dirty mouth discharge, automatic exhaust steam valve, guarantee the normal operation of equipment.

It is welded with handle on the hanging plate, is screwed out filter vat from outlet tube by handle, structure is simple, easy to operate Fast.
