Abstract
The utility model particularly relates to a rotating drum filter section of a horizontal screen sedimentation centrifuge convenient for replacing screen modules. The rotating drum filter section comprises a filter section barrel, and is characterized in that: a plurality of screen modules are distributed on the filter section barrel; each screen module comprises a screen bracket and a screen fixed on the screen bracket; the screen bracket is in a square cylindrical structure; the screen is fixed on the middle part of the screen bracket; both sides of the screen bracket are provided with a plurality of fixing screw holes and ejection screw holes; and a fastening bolt passing through the fixing screw holes is arranged between the screen bracket and the filter section barrel. The rotating drum filter section has the advantages of reasonable structure, time-saving and labor-saving replacement and low cost. A replaceable screen module can be made into a standard spare part, the overhaul and maintenance of the rotating drum filter section can be completed easily and quickly without hoisting a housing and a rotor in the using field, a severely-worn screen module of the entire rotating drum filter section can be replaced partially, and the maintenance cost and overhaul time are greatly reduced.
Description
Technical field
The utility model is specifically related to a kind of horizontal screen-bowl sedimentation centrifuge rotary drum fillter section of convenient changing screen cloth module.
Background technology
Horizontal screen-bowl sedimentation centrifuge is a kind of equipment of coal slime dewatering efficiently, it combines the advantage that the centrifugal sedimentation separation separates with screen filtration, can the solid-liquid slip below the 3mm effectively be separated, be specially adapted to the dehydration of floatation clean coal, floating tail-coal and coal slime.This equipment extensive use and coal washing industry have obtained bigger social benefit and economic benefit.
Rotor is the core component of horizontal screen-bowl sedimentation centrifuge, also is consumable accessory simultaneously, and normal service life is in 2 years.Rotor maintenance and renewal cost costliness, rotor part accounts for 2/3 of price of complete machine, and because structure is limit, need and lift casing and the dismounting of whole rotor part during maintenance, therefore and space, washing workshop, coal washery is limited, overhauls that difficulty is big, the time is long, cost is high.
Rotor part comprises inner pushing spiral and two chief components of outside rotary drum, and rotary drum is divided into three sections again, is respectively settling section, compression section and fillter section, uses Bolt Connection between adjacent two sections.The material of settling section and compression section generally adopts carbon steel liner aluminium oxide ceramics.Because material carries out the centrifugal filtration dehydration at fillter section, centrifugate produces stronger impact wear to filter screen and draining hole wall under the effect of high centrifugal force, makes these position wearing and tearing rapidly.Therefore filter screen is generally selected high abrasion resisting materials such as aluminium oxide ceramics, stainless steel and tungsten carbide for use, directly influences the service life of whole rotor part the service life of rotary drum fillter section.
The utility model content
When changing, the rotary drum fillter section that the purpose of this utility model is to solve traditional horizontal screen-bowl sedimentation centrifuge need come out casing and the dismounting of whole rotor part and lifting, whole fillter section is changed, waste time and energy, the defective that influence is produced, when being provided, a kind of replacing fillter section need not casing and whole commentaries on classics are come out from parts dismounting and lifting, only need to change the screen portion on the fillter section, the horizontal screen-bowl sedimentation centrifuge rotary drum fillter section of time saving and energy saving, as not influence production convenient changing screen cloth module.
The utility model is achieved by the following technical solution:
It is a kind of horizontal screen-bowl sedimentation centrifuge rotary drum fillter section of convenient changing screen cloth module, comprise the fillter section cylindrical shell, it is characterized in that being distributed with on the fillter section cylindrical shell a plurality of screen cloth modules, described screen cloth module comprises screen cloth support and the screen cloth that is fixed on the screen cloth support, the screen cloth support is square tubular, screen cloth is fixed on the middle part of screen cloth support, and the both sides of screen cloth support are provided with a plurality of fixing threaded holes and eject screw, are provided with between screen cloth support and the fillter section cylindrical shell and pass the fixing threaded hole fastening bolt.
Fixing threaded hole and eject the both sides that screw is distributed in the screen cloth support.
Screen cloth module described in the utility model, its screen cloth can be fixed on the screen cloth support by welding or glued mode.
The utlity model has advantage rational in infrastructure, that replacing is time saving and energy saving, cost is low.Adopt advantage of the present utility model to be, replaceable screen cloth module is made standardized standby redundancy, on-the-spotly need not that case and rotor are carried out lifting operation and can easily finish repair and maintenance fast using the rotary drum fillter section, screen cloth module to whole drum fillter section serious wear can be carried out local replacing, greatly reduce maintenance cost and repair time, improved the economic benefit of horizontal screen-bowl sedimentation centrifuge.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A cutaway view among Fig. 1;
Fig. 3 is the perspective view of screen cloth module
As shown in FIG.: 1 fillter section cylindrical shell; 2 screen cloth modules; 2-1 screen cloth support; 2-2 ejects screw; The 2-3 fixing threaded hole; The 2-4 screen cloth.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further elaborated.
As Fig. 1, Fig. 2, shown in Figure 3: a plurality of screen cloth modules 2 are installed on the fillter section cylindrical shell 1, screen cloth module 2 is installed on the fillter section cylindrical shell 1 by fastening bolt, screen cloth module 2 comprises that square screen cloth support 2-1, screen cloth support 2-1 are square tubular, and screen cloth 2-4 is fixed to screen cloth support 2-1 middle part by welding or glued mode.The screen cloth support 2-1 left and right sides is provided with fixing threaded hole 2-3 spaced apart, ejects screw 2-2.
When the utility model is installed, each screen cloth module 2 is fixed on the fillter section cylindrical shell 1 by the fastening bolt that passes fixing threaded hole 2-3 gets final product, screen cloth 2-3 wearing and tearing on screen cloth module 2, when needing to change, need not integral replacing, only need fastening bolt is backed out, by ejecting screw 2-2 this screen cloth module 2 is pulled down, change new screen cloth module 2 again and get final product, whole replacing process is time saving and energy saving, and cost is low.
