Technical Field
The invention relates to the technical field of a smoke exhaust system, in particular to a smoke exhaust system of a cold paste ramming table assembled on a cathode of an aluminum electrolytic cell.
Background
In the overhaul workshop of the aluminum electrolysis plant cell, the cathode assembly working section finishes the assembly of the cathode carbon blocks and the cathode steel bars by adopting a paste tamping mode after finishing the cleaning of the cathode steel bars, the preheating of the cathode carbon blocks and the preheating of paste materials of the cathode steel bars. The temperature of the cathode steel bar cold paste is about 60 ℃, the two sides of the ramming platform are worker ramming operation areas, and in order to remove the diffused smoke, the conventional smoke discharging scheme is as follows: a side suction cover is arranged at the end part of the ramming platform or a movable cover is arranged at the upper part of the ramming platform, and the arrangement position of a cover opening is close to the ramming platform as much as possible and does not influence the operation of workers and the hoisting of a steel bar to an assembly station by a crown block. The scheme has the following defects: 1. in order to ensure the hoisting of the cathode carbon block and the cathode steel bar, the position of the cover is far away from a smoke generating point, and the air exhaust effect is poor; 2. the exhaust air flow passes through the breathing zone of the operators, and the health of the operators is seriously influenced.
To prior art not enough, the utility model provides an aluminium cell cathode assembly cold paste ramming platform system of discharging fume to outside the workshop will be effectively got rid of to ramming platform workspace harmful gas to minimum discharge fume volume, reduce smoke exhaust fan's amount of wind and wind pressure, improve energy utilization efficiency, reduce the environment negative effect, economic benefits is good moves reliably simultaneously. The method plays an important role in guaranteeing the occupational safety and the health of workers in the cold paste ramming table area.
SUMMERY OF THE UTILITY MODEL
To the existing problem, the utility model provides a cold thickener of aluminium cell cathode assembly ramming platform system of discharging fume.
The utility model discloses a cold thickener is beaten platform and is buried the ground exhaust hood, the inner chamber that cold thickener was beaten platform is equipped with the material of beating, the material of beating is cold thickener, both sides all are provided with and bury the ground exhaust hood around the cold thickener is beaten the platform, bury the ground exhaust hood and arrange in the lower part of beating the platform to bury the ground exhaust hood and do not influence the workman's operation, bury the top of ground exhaust hood and install strip seam apron, the right side of burying the ground exhaust hood is equipped with the union, the left side of burying the ground exhaust hood is equipped with the hoist and mount ear, the right side of burying the ground exhaust hood is connected with the one end of tuber pipe governing valve through the union, the other end of tuber pipe governing valve is connected with exhaust pipe's one end, exhaust fan is installed to exhaust pipe's the other end, exhaust fan's top is.
Buried exhaust hood arranges in ramming platform workman operation area underground, through top strip seam apron and ramming platform workspace intercommunication, cold thickener disperses gaseous does not have the power that the hot gas flow rises, it is nearer apart from strip seam apron, the thickener that the ground splashes among the ramming process, drop to buried exhaust hood in through strip seam apron, regularly bury exhaust hood and connecting tube in the split of union department, utilize and bury ground exhaust hood hoist and mount ear with it and hoist out the trench, concentrate clearance and retrieve the interior thickener of utilization cover, it is extravagant to reduce the raw materials, after reassembly buries ground exhaust hood and pipeline, continue to discharge fume the use, strip seam apron is convenient for observe the blanking volume in burying ground exhaust hood.
The utility model discloses a theory of operation does: the air exhaust amount of the buried exhaust hood enables a ramming table area to form negative pressure, smoke generated in the process of entrainment and ramming and surrounding airflow form a downward airflow operation trend, the smoke is exhausted out of a workshop through the buried exhaust hood and an exhaust pipeline, the airflow of an operation area is controlled to be downward so that the smoke does not pass through a breathing area of an operator, meanwhile, the negative pressure of a local space enables fresh air which penetrates into the space through doors and windows to flow into the polluted negative pressure area after passing through a personnel breathing area, and the operation environment of the operator is improved.
The utility model discloses a cold thickener flue gas flow characteristic when ramming will bury the ground exhaust hood and arrange in the flue gas and disperse the district lower part, unanimous with its flue gas flow direction, guarantees simultaneously that its flow path does not pass through operating personnel breathing zone, improves the air current collection efficiency of discharging fume, lowers system's equipment operation energy consumption, will play important role in cold thickener ramming system.
