Abstract
The utility model discloses a split rotor block, which comprises a support and a rotor body. The rotor body is detachably connected with the support through a fastening part and comprises a plurality of rotor components which are detachably connected by connecting parts. The split rotor block in a split structure can be split into a plurality of portions, a top cover of a coal mill needs no detachment when the rotor block needs replacement during overhaul of the coal mill, only a door plate of a loading device needs to be detached, and the rotor block split into the portions can be placed into the coal mill and then assembled into a whole. The split rotor block can be replaced conveniently and rapidly, installation and maintenance workload is decreased greatly, and downtime of a unit is shortened, so that economy of a whole system can be improved.
Description
Technical field
The utility model relates to the dynamic/sound attitude separator in the coal pulverizer, relates in particular to a kind of split-type rotor block.
Background technology
Coal pulverizer is one of most important equipment in the pulverized coal preparation system, and in order to satisfy the instructions for use of energy-conserving and environment-protective, now increasing coal pulverizer all has been equipped with dynamically/sound attitude separator.Rotor block is one of core component of dynamic/sound attitude separator, and the quality of its performance has directly determined the economy of coal pulverizer and even whole pulverized coal preparation system.
The rotor block long-term work is in dust atmosphere, and be generally 2-3 its service life, belongs to one of consumable accessory of dynamic/sound attitude separator, must change rotor block when the coal pulverizer overhaul.But the present rotor block of producing all adopts monolithic construction, the top cover and the associated conduit of coal pulverizer must be removed when changing rotor block, and workload is very huge, has prolonged the downtime of unit greatly, has reduced the economy of whole system.
The utility model content
The purpose of this utility model just provides a kind of split-type rotor block, changes trouble with the rotor block that solves the monolithic construction that above-mentioned prior art exists, and workload is big, the problem that the compressor emergency shutdown time is long.
The purpose of this utility model is achieved through the following technical solutions:
A kind of split-type rotor block comprises support and rotor body, and described rotor body removably connects by securing member and support; Described rotor body comprises some rotor components, and these some rotor components removably connect by connector.
The base plate of described rotor body is connected the location with connector by alignment pin.
Described connector comprises some connecting plates and bolt, and connecting plate connects the adjacent rotors component and by being bolted on the rotor component.
Described connector comprise be separately positioned on the adjacent rotor component, and the buckle and the draw-in groove of corresponding clamping.
Described securing member is a bolt, and rotor body removably connects by bolt and support.
Preferably, be provided with flange below the described support.
Compared with prior art, the utlity model has following beneficial effect:
Split-type rotor block of the present utility model is a split-type structural, the removable several portions that is divided into, in the time of during the coal pulverizer overhaul, will changing rotor block, do not need to remove the coal pulverizer top cover, only the door-plate of charger need be removed, the rotor block that can will be split as several portions is put into coal pulverizer inside, and then its assembling is in aggregates.Use split-type rotor block of the present utility model and can conveniently change rotor block, significantly reduce the installation and maintenance workload, shorten the downtime of unit, the economy of whole system is improved.
Description of drawings
Fig. 1 is the structural representation of the utility model one embodiment;
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
Describe the utility model in detail below in conjunction with accompanying drawing.
As shown in Figure 1, 2, a kind of split-type rotor block of the present utility model comprises support 1 and rotor body 2, and support 1 is an overall structure, and rotor body 2 removably connects by securing member and support 1.Securing member has various ways in the specific embodiment, securing member is a bolt in the present embodiment, and rotor body 2 removably connects by bolt and support 1.
Rotor body 2 comprises two (being example with two) rotor components here, is connected to form by two rotor components.These two rotor components removably connect by connector, in the present embodiment, connector is first connecting plate 3, second connecting plate 4, the 3rd connecting plate 5 and a plurality of bolt, first connecting plate 3, second connecting plate 4, the 3rd connecting plate 5 connect adjacent two rotor components respectively and by bolt connecting plate are fixed on the rotor component, two adjacent rotor components can be coupled together.Be that rotor body 2 may be split into two rotor components, these two rotor components are assembled into an integral body by first connecting plate 3, second connecting plate 4, the 3rd connecting plate 5, and promptly rotor body 2.
In the specific embodiment, connector can also be the buckle and the draw-in groove of corresponding clamping, and wherein buckle and draw-in groove are corresponding respectively is arranged on two adjacent rotor components, and buckle and draw-in groove correspondence are interlocked, and two adjacent rotor components can be coupled together.
Boring between the base plate 6 of rotor body and the 3rd connecting plate 5, and alignment pin 8 is installed is connected the location, with guarantee rotor block is installed to dynamically/have higher precision during sound attitude separator.
Preferably, the stability when moving in order to increase split-type rotor block of the present utility model, support 1 below is provided with two circle flanges 7.
In the time of during the coal pulverizer overhaul, will changing rotor block, do not need to remove the coal pulverizer top cover, only need the door-plate of charger is removed (the door-plate workload of removing charger is smaller), then support, the rotor body that is split as two rotor components, first connecting plate, second connecting plate, the 3rd connecting plate and a plurality of bolt are put into coal pulverizer inside by the charger door.Earlier the output shaft of support with dynamic/sound attitude separator connected together with bolt, alignment pin is installed between rotor body base plate and the 3rd connecting plate again and two rotor components is assembled into an integral body with first connecting plate, second connecting plate, the 3rd connecting plate, with bolt itself and support are secured together at last, can finish installation, the replacing of rotor block.Whole process installation and maintenance workload is smaller, can shorten the downtime of unit greatly.
Split-type rotor block of the present utility model is a split-type structural, the removable several portions that is divided into, in the time of during the coal pulverizer overhaul, will changing rotor block, do not need to remove the coal pulverizer top cover, only the door-plate of charger need be removed, the rotor block that can will be split as several portions is put into coal pulverizer inside, and then its assembling is in aggregates.Use split-type rotor block of the present utility model and can conveniently change rotor block, significantly reduce the installation and maintenance workload, shorten the downtime of unit, the economy of whole system is improved.
More than disclosed only be several specific embodiments of the application, but the application is not limited thereto, any those skilled in the art can think variation, all should drop in the application's the protection domain.
