Abstract
The utility model discloses a subsider underflow pump import filter equipment, including subsider, filter, underflow pump, the pyramis of subsider is connected in filter import, filter exit linkage in underflow pump import, and the filter is equipped with filter screen, gas vent, hand hole, and the underflow pump drives the operation of underflow pump subsider inside slurry seeing off continually through the motor operation. The utility model discloses simple structure, cost are hanged down, and installation convenient to use has avoided the violent change owing to system temperature, pressure, and the dirty piece in the grey water system comes off in a large number, along with hydrologic cycle entering subsider, result in a dirt entering underflow impeller of pump, lead to the fact the frequent maintenance and the damage of pump, influence the problem of device steady operation, have improved the productivity effect.
Description
Technical field
This utility model relates to gasifying powder coal device apparatus field, specifically a kind of subsider underflow pump inlet filtering apparatus.
Background technology
At present, in space flight stove gasifying powder coal device, part fine ash, fine slag that gasification furnace produces in combustion eventually enter into subsider by the grey water circulation system of gasification system and carry out flocculating sedimentation process, subsider center is mounted with that the mud scraper of a slow rotation delivers to the outlet bottom subsider the slurry settled down, and the slurry of the thickening settled out bottom subsider is delivered to vacuum band-type filter machine by subsider underflow pump and filtered.During gasification installation start-stop car, due to system temperature, the acute variation of pressure, the dirty sheet in system is caused to come off in a large number, along with water is recycled into subsider, dirt sheet is caused to enter underflow pump impeller, cause the frequently maintenance of pump and damage, having influence on the normal discharge of slurry, eventually affect the stable operation of gasification installation.
Utility model content
The purpose of this utility model is to provide a kind of subsider underflow pump inlet filtering apparatus, to make up the deficiency of prior art, solve due to system temperature, the acute variation of pressure, dirty sheet in ash water system comes off in a large number, along with water is recycled into subsider, cause dirt sheet to enter underflow pump impeller, cause the frequently maintenance of pump and damage, have influence on the normal discharge of slurry, the problem eventually affecting the stable operation of gasification installation.
In order to achieve the above object, the technical scheme that this utility model is used is:
A kind of subsider underflow pump inlet filtering apparatus, it is characterized in that: include subsider, filter, underflow pump, vacuum band-type filter machine, described subsider has conical lower portion, conical lower portion is provided with outlet, and subsider outlet is connected with filter inlet by pipeline, being provided with filter screen in described filter, filter outlet is connected with underflow pump import by pipeline, and described vacuum band-type filter machine accepts underflow pump outlet.
Described a kind of subsider underflow pump inlet filtering apparatus, it is characterised in that: described filter bottom has hand hole.
Described a kind of subsider underflow pump inlet filtering apparatus, it is characterised in that: described filter top has steam vent.
In this utility model, underflow pump is run by motor and drives underflow pump operation that internal for subsider slurry is sent endlessly.Being provided with filter between its subsider tapering and underflow pump, for the foreign material etc. such as dirty sheet of filtration system, stabilisation systems is run.
It is provided with filter, for the foreign material etc. such as dirty sheet of filtration system, when filter differential pressure raises between subsider tapering and underflow pump, directly by foreign material such as filter hand hole cleaning dirt sheets, decreasing the hard work opening and inspecting underflow pump, reduce the fault rate of pump, the system that stabilizes is run.
The utility model has the advantages that:
1, this utility model simple in construction, cost are low, easy to install.
2, avoiding due to system temperature, the acute variation of pressure, the dirty sheet in ash water system comes off in a large number, along with water is recycled into subsider, dirt sheet is caused to enter underflow pump impeller, cause the frequently maintenance of pump and damage, the problem affecting device stable operation, improve productivity effect.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Detailed description of the invention
Shown in Figure 1, a kind of subsider underflow pump inlet filtering apparatus, include subsider 1, filter 2, underflow pump 3, vacuum band-type filter machine 4, subsider 1 has conical lower portion, conical lower portion is provided with outlet, and subsider 1 is exported and is connected with filter 2 import by pipeline, is provided with filter screen 5 in filter 2, filter 2 is exported and is connected with underflow pump 3 import by pipeline, and vacuum band-type filter machine 4 is accepted underflow pump 3 and exported.
Hand hole 6 is had bottom filter 2.Filter 2 top has steam vent 7.
