Abstract

The utility model discloses a sleeve type filter which comprises a barrel-shaped body with a liquid inlet and a liquid outlet and a filter cylinder arranged in the body. The sleeve type filter is characterized in that the upper and the lower ends of the barrel-shaped body are closed; the liquid inlet and the liquid outlet are respectively arranged at two sides of the barrel-shaped body; the filter cylinder and the barrel-shaped body are equal in height; the filter cylinder and the axial line of the barrel-shaped body are arranged in parallel; the barrel-shaped body is divided into a filter chamber and an exhaust chamber by the filter cylinder; a liquid inlet insert tube communicated with the liquid inlet is arranged in the barrel-shaped body; the head end of the insert tube is inserted in the filter chamber of the filter cylinder; and a sewage outlet with a valve is arranged at the bottom part of the filter chamber. The utility model has the advantages of simple structure, low cost, on-line slag discharge, back washing and the like.

Description

Telescopic filter

Technical field

The utility model relates to filter, specifically be meant and a kind ofly from have corrosive liquid, isolate solid particle polluter, be installed on the telescopic filter on the process pipe, can be widely used in fields such as chemical industry, medical medicine, oil, metallurgy, weaving, food, water treatment.

Background technology

Piping filter is to carry indispensable a kind of device on the pipeline of various media.Present widely used piping filter has y-type filter, basket filter, T type filter etc.Its operation principle is: when liquid entered piping filter, filter element filtered the solid particle polluter in the liquid that flows through in this piping filter, reached the purpose of decontaminating liquid.But this filter is in use because the accumulation of solid particle polluter, need often the filter element in this filter to be disassembled from pipe-line system to carry out deslagging, cause and use inconvenience, waste man-hour, and this filter in use solid particle polluter will inevitably be adsorbed on the filter screen of filter element, cause and pressure occurs inside and outside the filter screen and fall, after pressure falls above certain value, could dismantle filter element after also filter must being completely cut off from pipe-line system cleans, recover function of use, also cause very big use inconvenience, and frequent disassembly, cleaning filter, must often cause pipeline not transport liquid consistently, cause the inefficiency of pipeline transportation liquid.At present, though the piping filter that has can online deslagging and backwash, because of its structure is complicated, the application on corrosive liquid is restricted.

The utility model content

The purpose of this utility model is in order to overcome the shortcoming and defect that prior art exists, and provides a kind of structure to be provided with simply, low price, can online deslagging and the telescopic filter of backwash.

For achieving the above object, the technical solution of the utility model is, include the tubular body of band inlet and liquid outlet, place intrinsic filter cylinder, it is characterized in that: the closed at both ends up and down of described tubular body, and this described inlet and liquid outlet are separately positioned on the both sides of tubular body, described filter cylinder and tubular body are contour, and the axis parallel setting of this filter cylinder and tubular body, this filter cylinder is separated into filter chamber and exhaust chamber with the tubular body, be provided with the feed liquor intubate that is communicated with inlet in the described tubular body, the head end of this intubate is inserted into the filter chamber in the filter cylinder, and the bottom of described filter chamber is provided with the sewage draining exit that has valve.

As to such scheme further replenish and perfect, the utility model can also preferably have following technical scheme, the upper end of described tubular body seals by loam cake, its lower end is sealed by base.Described loam cake connects with the tubular body by bolt and nut with base.

Advantage of the present utility model is: can online deslagging (need not dismantle and can discharge impurity) but and backwash, when the accumulation of the solid particle polluter in the filter chamber needs deslagging, only need to open sewage draining exit, close inlet, open liquid outlet, the anti-clear liquid of sending in simultaneously from liquid outlet toward the tubular body, just can be implemented in the line deslagging and and remove the solid particle that adheres on the filter screen, reduce the resistance drop of filter, overall process need not any dismounting, simple to operation, and speed is fast.

Below in conjunction with specification drawings and specific embodiments the utility model is done further introduction.

The specific embodiment

The specific embodiment of the present utility model as shown in Figure 1, include the tubular body 1 of band inlet 11 and liquid outlet 12, place intrinsic filter cylinder 2, the closed at both ends up and down of described tubular body 1, the upper end of the described tubular body 1 of present embodiment is by loam cake 3 sealings, its lower end is by base 4 sealings, and this loam cake 3 connects with the tubular body by bolt and nut with base 4, described inlet 11 and liquid outlet 12 are separately positioned on the both sides of tubular body 1, described filter cylinder 2 is contour with tubular body 1, and the axis parallel setting of this filter cylinder 2 and tubular body 1, this filter cylinder 2 is separated into filter chamber 13 and exhaust chamber 14 with tubular body 1, be provided with the feed liquor intubate 15 that is communicated with inlet 11 in the described tubular body 1, the head end of this feed liquor intubate 15 is inserted into the filter chamber 13 in the filter cylinder 2, and the bottom of described filter chamber 13 is provided with the sewage draining exit 16 that has valve.

The utility model can online deslagging (need not dismantle and can discharge impurity) but and backwash, shown in Figure 3 as Fig. 2, when the accumulation of the solid particle polluter in the filter chamber 13 needs deslagging, only need to open sewage draining exit 16, close inlet 11, open liquid outlet 12, the anti-clear liquid of sending in simultaneously from liquid outlet 12 toward tubular body 1, just can be implemented in the line deslagging and and remove the solid particle that adheres on the filter screen, reduce the resistance drop of filter, overall process need not any dismounting, and is simple to operation, and speed is fast.

For the applicability that improves this product being fit to situations such as different media, temperature, the described filter of present embodiment adopts carbon steel material to the case member of contact process medium not, so can reduce cost; To the material of the overcurrent part of contact processing medium is that difference according to applying working condition can adopt macromolecular material such as polytetrafluoroethylene (PTFE), polyolefin and stainless steel material etc. respectively.
