Specific embodiment
Below with reference to examples and drawings, the utility model is described in more detail, but the reality of the utility model
It is without being limited thereto to apply mode.
A kind of screen pipe, generally cylindrical-shaped structure, the screen pipe of cylindrical-shaped structure are conducive to weight particle convenient for erectting installation
Object voluntarily settles, and does not influence sampling analysis.Applied to the filter module in the in-situ monitoring and portable monitoring device of different water bodys
Block including chimney filter, strainer, pressure ring, two sealing rings and is respectively threadedly attached in the chimney filter connector and chimney filter at chimney filter both ends
Head.
Chimney filter head is cylinder-like structure, and upper end is equipped with external screw thread, and externally threaded bottom is equipped with the second seal groove, externally threaded
Top is equipped with pressure ring slot.Pressure ring is cirque structure, and strainer is mounted on chimney filter head, and pressure ring pushes down strainer and is mounted on pressure ring slot
On.Strainer is compressed with pressure ring, is covered on chimney filter head, and strainer and pressure ring are located in chimney filter, is not influenced overall appearance, is also easily removable
Installation.The circumferential direction of chimney filter head lower end and bottom are equipped with recirculation hole, facilitate water to flow into filtering access, improve sample rate.Circulation
The pore diameter range in hole is 0.5-5mm, filters the biggish sundries of particle using the size in aperture, sundries is avoided to enter chimney filter head inner product
Strainer front end is got lodged in, it can be to the abrasion of the excessive pressure of filter screen and then accelerated filtration net while leading to filter blockage.
Chimney filter connector is cylinder-like structure, and lower end outside is equipped with external screw thread, inside is equipped with inverted funnel shape hole, is set inside upper end
There is hose joint threaded hole, hose joint threaded hole is connect with hose, using hose convenient for water sample extraction, externally threaded bottom
Portion is equipped with the first seal groove.Inverted funnel shape hole is conducive to drainage water sample bubble and air discharge, meets sample capacity, reduces sampling
Time and detection and analysis time.Hose joint threaded hole is for being threadedly coupled hose.Two sealing rings are respectively sleeved at first
At seal groove and the second seal groove.When screen pipe extracts water sample water and rises from lower to upper, bubble and air pass through inverted funnel shape hole,
Bubble and air can be drained, the sample time is shortened, guarantees sampling capicity.
Chimney filter is annular structure, and both ends are equipped with internal screw thread and internal screw thread bottom is equipped with supporting table, and respectively top is held
Saddle and lower part supporting table, upper end and the chimney filter connector of chimney filter are connected through a screw thread, and the lower end of chimney filter and chimney filter head pass through screw thread
Connection.Chimney filter connector and chimney filter head are connected through a screw thread with chimney filter, and it is firm to connect.Pressure ring is compressed using lower part supporting table, into
One step fixes strainer, prevents strainer from loosening.
Chimney filter, chimney filter connector and chimney filter head are made of PVC, and chimney filter is made of acrylic.Transparent chimney filter facilitates observation
Inside sampling situation, understands sampling quality and filter net jam degree.
Recirculation hole, chimney filter head, chimney filter, chimney filter connector are connected to form filtering access with hose；When sampling, chimney filter head is immersed in
It samples in liquid.Water sample flows into chimney filter head by recirculation hole, and sequentially enters chimney filter, chimney filter connector and hose, flows to sampler
Structure or instrument.
Upward by the chimney filter connector of the screen pipe installed, chimney filter upside down, is immersed in the liquid for needing to sample, and liquid is logical
It crosses recirculation hole and enters chimney filter head lower space, recirculation hole can filter out bigger material, and water sample is further by mounted strainer
Water sample is filtered, meets sampling requirement, into chimney filter；Water sample is stepped into from lower to upper in the inverted funnel shape hole of chimney filter connector,
When reaching the endpiece in inverted funnel shape hole, aperture becomes smaller, and pressure becomes larger, promote air, bubble by inverted funnel shape hole into
Enter in hose and evacuates.Sampling at this time can start to calculate sample time, control sampling capicity, facilitate down-stream control.
Strainer is such as needed to change or cleaned, screen pipe is taken out from sampling mechanism or instrument, dismounting and change or flushing, side
Just succinct, the operating time is short, with changing with being not necessarily to complex operations.
Other than the mode that above-described embodiment refers to, it can be not provided with sealing for the not high service condition of sealing requirements
Circle.Further filtering can also be done again in chimney filter connector and chimney filter junction installation strainer, meet filtering requirement.These transformation sides
Formula is within the protection scope of the present utility model.
Above-described embodiment is the preferable embodiment of utility model, but the embodiments of the present invention is not by above-mentioned reality
Apply the limitation of example, it is made under other any spiritual essence and principles without departing from the utility model change, modification, substitution,
Combination simplifies, and should be equivalent substitute mode, is included within the protection scope of the utility model.
