Abstract
The invention discloses a mesh screen cleaning device. An inlet pipe (3) and a cleaning opening (4) are arranged on a top cover (2) of a shell (1); coal ash fall into a mesh screen (5), scouring a blade (6) under the mesh screen, so that the mesh screen is rotated around a rotating shaft (8) supported by a bearing (7); the coal ash filtered by the mesh screen is intensively delivered from an outlet pipe (11); a development testing (DT)-rotary drum intelligent sensor (9) outputs the rotary speed information of a band magnetic steel slice rotating wheel (10) to a control room and provides for an operation personnel to judge whether the mesh screen shall clean impurities on the mesh screen timely or not.
Description
Technical field that the present invention belongs to
The present invention relates to a kind of monitoring device of telemonitoring mesh screen rotary state.
Prior art and background technology
The existing fly ash air-transport system in coal-burning power plant never arranges the mesh screen cleaning plant, and especially after the dust exhaustor maintenance, the foreign material that human element is brought into can not get timely cleaning, can cause the accident of blocking pipe and damage rotating machinery.
The purpose of invention
The objective of the invention is in ash-transmission system, to install the mesh screen cleaning plant additional, but the rotary state of telemonitoring mesh screen judge whether to clear up foreign material, with the accident of avoiding causing plugging and damaging rotating machinery because can not in time clearing up foreign material.
The technical scheme of invention
The objective of the invention is to be achieved by the following measures: the top cover (2) at mesh screen cleaning plant housing (1) is provided with induction pipe (3) and clean-up port (4), fly ash falls into mesh screen (5), wash away the blade (6) below the mesh screen, mesh screen is centered on by the rotating shaft (8) of bearing (7) support to rotate, the fly ash that filters through mesh screen concentrates on outlet pipe (11) and sends, and transfer to control cabin by the rotary speed information of DT-rotating cylinder intelligent transducer (9) output band magnetic links runner (10), offer the operations staff and judge whether mesh screen should in time clear up the foreign material on the mesh screen.
The good effect that invention compared with prior art has
Existing defeated gray technology is not establish the mesh screen cleaning plant, dust exhaustor is after maintenance, make easily ash-transmission system sneak into some larger foreign material and accidents caused, the normal operation of the defeated ash work of impact, after the mesh screen cleaning plant has been installed, just can avoid causing because of the foreign material in the defeated ash generation of stifled ash and damage accident.
The description of the drawings
Below in conjunction with drawings and embodiments, the mesh screen cleaning plant is described further.
Accompanying drawing is the scheme drawing of mesh screen cleaning plant:
1. housing 2. mesh screen top covers 3. induction pipes 4. clean-up ports 5. mesh screens, 6. blades, 7. bearings, the 8. rotating shaft 9.DT-rotating cylinder intelligent transducers 10. of mesh screen cleaning plant are with the runner 11. fly ash outlet pipes of magnetic links
Concrete embodiment
Above defeated grey transmission system rotation air-locked type machine supplying powder, a mesh screen cleaning plant is installed, fly ash washes away blade by ash bucket according to the mesh screen that deadweight falls into the mesh screen cleaning plant, mesh screen is rotated, if be mixed with than bigger material in the fly ash that falls, its foreign material are stopped the rotating speed that affects mesh screen by screen cloth, the information of DT-rotating cylinder intelligent transducer output mesh screen rotating speed, the operations staff is according to the information of the rotating speed that is transferred to control cabin and state of kinematic motion, the operations staff can judge whether to carry out the foreign material cleaning work, ensures the safe operation of ash-transmission system.
Claims (1)
1. mesh screen cleaning plant, it is characterized in that: the top cover (2) at mesh screen cleaning plant housing (1) is provided with induction pipe (3) and clean-up port (4), fly ash falls into mesh screen (5), wash away the blade (6) below the mesh screen, screen cloth is centered on by the rotating shaft (8) of bearing (7) support to rotate, the fly ash that filters through mesh screen concentrates on outlet pipe (11) and sends, and transfer to control cabin by the rotary speed information of DT-rotating cylinder intelligent transducer (9) output band magnetic links runner (10), offer the operations staff and judge whether mesh screen should in time clear up the foreign material on the mesh screen.
