Abstract

The utility model relates to a sewage removing device for heating system, is common equipment in hot water heating system, and is used for clearing and filtering impurity and dirt in pipes. The sewage removing effect of existing sewage removing device is not good, the existing sewage removing device is easy to clog and repairing is inconvenient. The utility model utilizes centrifugation and inertial actions of liquid, and is composed of a reducing pipe, an arc baffle valve, a blow-down pipe, a filter net, etc. The sewage removing effect has advantage over the original sewage removing device, due to convenient washing or replacing the filter net, the filter net can avoid clogging, and therefore, flow resistance is reduced.

Description

Sewage removing device for heating system

The utility model belongs to building trade heating system equipment.

Dirt separator is an equipment common in the hot water system, is mainly used in impurity and dirt in removing and the filter pipeline.Existing dirt separator scrubbing poor effect, and easily stop up and inconvenient maintenance.The dirt separator of widespread usage has vertical straight-through dirt separator, horizontal straight-through dirt separator and horizontal angle to lead to dirt separator at present.The screen pack that vertical straight-through dirt separator adopts is the water outlet floral tube in φ=4mm hole; and dirt separator water inlet pipe and outlet pipe are on same horizontal line; though the dirt of larger particles can obtain sedimentation, because the ejector action of water outlet floral tube aperture, tiny sand grains still can flow to system through aperture.The logical dirt separator in horizontal straight-through dirt separator and horizontal angle only can be removed some suspensions owing to filter dirt by filter screen, can not stop that to the granule dirt therefore, above-mentioned several dirt separators all exist aperture or filter screen possibility of jamming, have increased fluid resistance thus.Moreover the building trade heating system generally all adopts cast-iron radiator, and casting sand is difficult to clean up in it, and along with circulating of heat supply networking water, casting sand will enter heat supply network.And the deficiency of above-mentioned several dirt separator can cause casting sand to stop up boiler tube bundle sometimes and cause that the boiler pipe explosion accident happens occasionally.For addressing these problems, the utility model provides a kind of novel dirt separator.

This novel dirt separator utilizes the centrifugal action of fluid and the impurity in the effect of inertia convection cell and dirt to carry out repeatedly scrubbing row dirt, thereby has realized new scrubbing effect.

The utility model is by reducer pipe ［ 1 ］, curved tailgate ［ 2 ］, and support ［ 3 ］, upper cover ［ 4 ］, valve ［ 5 ］, ［ 6 ］, blow-off pipe ［ 7 ］, filter screen ［ 8 ］, outlet pipe ［ 9 ］ and cylindrical shell ［ 10 ］ constitute.

System water supply enters dirt separator by reducer pipe ［ 1 ］, because the delivery port diameter diminishes, the speed that water flows out increases, after high-velocity fluid is gone out the mouth of pipe, directly hit on curved baffle ［ 2 ］, a part is consolidated the shape foreign material because collision course changes, and by means of the inertia sedimentation; The solid shape foreign material of another part are owing to the fluid mobile section increases, and fluid velocity reduces suddenly, and by gravitational settling.Removing the fluid of solid shape foreign material removes suspension again and enters system through support ［ 3 ］ copper filter screen ［ 8 ］ all around.

Below in conjunction with description of drawings most preferred embodiment of the present utility model.

This dirt separator cylindrical shell ［ 10 ］ and upper cover ［ 4 ］ are that steel plate is made.The also available steel pipe manufacturing of cylindrical shell ［ 10 ］.The central opening of upper cover ［ 4 ］ is upwards drawn outlet pipe ［ 9 ］, outlet pipe ［ 9 ］ upper end bolting valve ［ 5 ］, the inwall of upper cover ［ 4 ］ is equipped with support ［ 3 ］, overlaps copper filter screen ［ 8 ］ on every side at support ［ 3 ］, welds a curved baffle ［ 2 ］ in support ［ 3 ］ lower end.Cylindrical shell ［ 10 ］ lower ending opening is adorned a reducer pipe ［ 1 ］, use bolting valve ［ 6 ］ in reducer pipe ［ 1 ］ outer end, reducer pipe ［ 1 ］ in cylindrical shell ［ 10 ］ upward opening and outlet ［ 9 ］ opening on same axis, cylindrical shell ［ 10 ］ lower end extreme lower position and with reducer pipe ［ 1 ］ relative direction place opening dress blow-off pipe ［ 7 ］.

Claims

1, the novel dirt separator of a kind of heating system is characterized in that it is by reducer pipe [1], curved tailgate [2], and support [3], upper cover [4], valve [5], [6], blow-off pipe [7], filter screen [8], outlet pipe [9] and cylindrical shell [10] constitute.
