Abstract
The utility model discloses an improved 2250-millimeter hot continuous rolling mud treating system, which belongs to a sewage treating facility in the metallurgical industry. The treating system comprises a plate-frame press filter, an air compressor and a pneumatic control valve bank, wherein the plate-frame press filter is connected with an inverted valve through a mud conveying pipe; a mud feeding valve is arranged on the mud conveying pipe; the inverted valve is connected with the pneumatic valve through a gas conveying pipe; the pneumatic valve is connected with the air compressor through the gas conveying pipe; and the pneumatic control valve bank is used for controlling the mud feeding valve and the pneumatic valve. The treating system is characterized in that: the gas conveying pipe between the pneumatic valve and the inverted valve is provided with a cut-off valve, and the pneumatic valve group bank is used for controlling the cut-off valve. Due to the adoption of the treating system, the phenomenon of communication of an acting air path of the pneumatic valve on a press filter body with a mud cake blowing air path can be avoided, the phenomenon of damage to a control electromagnetic valve and an executing mechanism of the pneumatic valve since muddy water reflows from the inverted valve to the acting air path of the pneumatic valve in a production running process is avoided, the service life of equipment is prolonged, and the normal running of a mud system is ensured.
Description
Technical field
The utility model belongs to the metallurgy industry sewage treatment facility, is specifically related to relate to 2250mm hot continuous rolling sludge treating system.
Background technology
Fig. 1 is the structural representation of existing 2250mm hot continuous rolling sludge treating system; It comprises plate and frame(type)filter press, air, pneumatic control valve group; Plate and frame(type)filter press connects reverse checkvalve through dredging tube; Reverse checkvalve connects pneumavalve through pneumatic tube, and pneumavalve connects air through pneumatic tube, pneumatic control valve group control Mud-intake valve and pneumavalve.
Because hot rolling system mud contains a large amount of iron, mud, wet goods impurity, cause reverse checkvalve to use some cycles after, not tight at the effect lower seal of greasy filth; Pressure filter body pneumavalve action gas circuit is communicated with, when pressure filter advances mud, owing to advance mud pressure greater than the source of the gas pipe pressure with mud cake blowing gas circuit; Slime water is flowed backward to pneumavalve action gas circuit from reverse checkvalve, get into pneumavalve topworks and control, cause pneumatic door to be failure to actuate with in the SV; Cause pneumavalve control SV and topworks to damage, can get into into mud surge pump gas circuit when serious, cause into the mud surge pump to be failure to actuate; Spare part takes and maintenance cost increases, and causes gas leakage simultaneously, increases energy consumption.
Summary of the invention
The utility model provides improved 2250mm hot continuous rolling sludge treating system, its objective is to prevent pneumavalve gas circuit string mud phenomenon, prolongs service life of equipment, guarantees the normal operation of sludge system.
The utility model comprises plate and frame(type)filter press, air, pneumatic control valve group; Plate and frame(type)filter press connects reverse checkvalve through dredging tube, and Mud-intake valve is arranged on the dredging tube, and reverse checkvalve connects pneumavalve through pneumatic tube; Pneumavalve connects air through pneumatic tube; Pneumatic control valve group control Mud-intake valve and pneumavalve is characterized in that the pneumatic tube between pneumavalve and the reverse checkvalve is provided with trip valve, pneumatic control valve group control trip valve.
The utility model installs trip valve additional before reverse checkvalve, when pressure filter advances mud, close pneumatic cut-off valve; Finish when advancing mud, after Mud-intake valve is closed, open pneumatic cut-off valve.Can prevent that like this pressure filter body pneumavalve action gas circuit from taking place with the phenomenon that mud cake blowing gas circuit is communicated with; Stop in the production run process slime water and flow backward to pneumavalve action gas circuit from reverse checkvalve; The phenomenon that causes pneumavalve control SV and topworks to damage takes place; Thereby prolonged service life of equipment, guaranteed the normal operation of sludge system.
