Abstract
The utility model provides a kind of air filter for blast furnace blower wind sucting chamber, including filter cylinder and screw rod, and blast furnace blower air draught chamber outer wall is equipped with spiral shell button, and screw rod is fixedly welded on spiral shell and buckles, and filter cylinder is linked together by screw thread pair and screw rod；Using the technical solution of the utility model, by increasing setting long bolt on air filter, service personnel is when replacing air filter, since screw rod extends the assembly space of spiral shell button, even if under dark working environment, service personnel personnel only need to touch screw rod, the installation site of filter cylinder and quickly centering installation site can be determined quickly, simultaneously, since spiro rod length is longer, service personnel is when installing filter cylinder, the length direction of screw rod can be used as the channeling direction of assembly, filter cylinder is correctly installed in place by guiding service personnel, improve assembling quality, reduce rigging error, it lays a good foundation to improve smelting iron and steel quality.
Description
Technical field
The utility model belongs to metallurgical technology equipment technology field more particularly to a kind of for blast furnace blower wind sucting chamber
Air filter.
Background technology
Currently, oxygen top blown oven process is widely used with smelting iron and steel technique, operation principle is sprayed from converter top
It is the smelting in steel that high pressure oxygen is blown into stove to strengthen steelmaking process and improve the converter steelmaking process of melting bath stirring by rifle
Sweetening process, in this smelting process, blast furnace blower is the important link in metallurgical technology equipment, and main function is for height
Stove, which is smelted, provides enough oxygen-containing airs, due to having larger impurity, moisture in air, in order to improve the combustion in blast furnace process
Burn efficiency, it is necessary to it is sent into wind sucting chamber and reuses after being filtered to the oxygen-containing air that blast furnace blower is blown into, therefore, it is necessary to
Corresponding air filter is set between wind sucting chamber and blast furnace blower, purified treatment, the prior art are carried out to oxygen-containing air
In, in order to keep the long-term Effec-tive Function of air filter, it is necessary to be regularly replaced to air filter, to ensure to rouse
The safe and stable and Effec-tive Function of wind turbine is usually mounted with more since wind sucting chamber's floor space is very big on air draught chamber outer wall
Air filter, when replacing air filter every time, service personnel must successively carry out more each air filter
It changes, labor intensity is larger, further, since working environment dark residing for wind sucting chamber, service personnel is difficult in dark environment
In centering and assembly are carried out to air filter, efficiency is relatively low, seriously restricts the normal production order of smelter.
Utility model content
In order to solve the above technical problems, the utility model provides a kind of air filtration for blast furnace blower wind sucting chamber
Device.
The utility model is achieved by the following technical programs.
The utility model provides a kind of air filter for blast furnace blower wind sucting chamber, includes mainly filter cylinder and spiral shell
Bar, blast furnace blower air draught chamber outer wall are equipped with spiral shell button, and the screw rod is fixedly welded on spiral shell and buckles, the filter cylinder by screw thread pair with
The screw rod links together.
The filter cylinder length is less than the spiro rod length.
The length of the screw rod is 900mm to 1000mm.
The screw rod is full flight screw.
It is identical that the screw rod and spiral shell buckle screw thread nominal diameter.
The air filter for blast furnace blower wind sucting chamber further includes locking member, locking member and screw rod end
End is fixedly connected, and the filter cylinder compression is made to fit on the spiral shell button outer end face.
The locking member is substituted using plain nut.
The beneficial effects of the utility model are：Using the technical solution of the utility model, by air filter
Long bolt is arranged in upper increase, and service personnel is when replacing air filter, since screw rod extends the assembly space of spiral shell button, i.e.,
Make under dark working environment, service personnel personnel only need to touch screw rod, you can determine the installation site of filter cylinder quickly
And centering installation site quickly, simultaneously as spiro rod length is longer, service personnel is when installing filter cylinder, the length direction of screw rod
The channeling direction of assembly is can be used as, filter cylinder is correctly installed in place, improves assembling quality, reduce dress by guiding service personnel
With error, lay a good foundation to improve smelting iron and steel quality.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
In figure：1- blast furnace blowers wind sucting chamber, 2- filter cylinders, 3- screw rods, 4- spiral shell buttons, 5- locking members.
Specific implementation mode
Be described further below the technical solution of the utility model, but claimed range be not limited to it is described.
As shown in Figure 1, the utility model provides a kind of air filter for blast furnace blower wind sucting chamber, including filter
Cylinder 2 and screw rod 3,1 outer wall of blast furnace blower wind sucting chamber are equipped with spiral shell button 4, and screw rod 3 is fixedly welded on spiral shell button 4, and filter cylinder 2 passes through spiral shell
Line pair links together with screw rod 3.
Using the technical solution of the utility model, by increasing setting long bolt, service personnel on air filter
When replacing air filter, since screw rod extends the assembly space of spiral shell button, even if under dark working environment, maintenance
Personnel personnel only need to touch screw rod, you can the installation site of filter cylinder and quickly centering installation site are determined quickly, meanwhile, by
Longer in spiro rod length, for service personnel when installing filter cylinder, the length direction of screw rod can be used as the channeling direction of assembly, guiding inspection
It repaiies personnel to be correctly installed in place filter cylinder, improves assembling quality, reduce rigging error, established to improve smelting iron and steel quality
Basis is determined.
Further, 2 length of filter cylinder is less than 3 length of screw rod.
Further, the length of screw rod 3 is 900mm to 1000mm.3 length of screw rod is longer, then screw rod 3 in assembling process
Guiding role it is more apparent, use and maintenance personnel installation is more convenient, and preferably the length of screw rod 3 is 950mm.
Further, screw rod 3 is full flight screw.
Further, screw rod 3 is identical with screw thread nominal diameter on spiral shell button 4.
Further, the air filter for blast furnace blower wind sucting chamber further includes locking member 5, locking member 5 and spiral shell
3 end of bar is fixedly connected, and the compression of filter cylinder 2 is made to fit on 4 outer end face of spiral shell button.
Further, locking member 5 is substituted using plain nut.
In a particular application, when which is installed, include the following steps：
Step 1：Prepare blast furnace blower wind sucting chamber 1,1 outer wall of blast furnace blower wind sucting chamber is equipped with multiple spiral shell buttons 4；
Step 2：Weld screw rod 3：Screw rod 3 is fixedly welded on step 1 spiral shell button 4；
Step 3：Filter cylinder 2 is installed：Filter cylinder 2 is set on screw rod 3.
Show to install the air filter of the utility model it is only necessary to 5min or so by being tested in practical application,
In the working time for substantially reducing service personnel, labor intensity is reduced, improves efficiency.
