Description
Technical Field
The invention relates to a multi-element composite necking plate for a necking part of a smoke chamber of a preheater of a cement kiln.
Background
At present, domestic cement kiln smoke chamber throat position adopts welding anchor assembly to beat the pouring material and uses, because this position operating temperature is high, the skinning is serious, cause the putty of pre-heater, the putty can cause the change of wind speed to influence production, and cause the putty to stop production, should stop the kiln to handle pouring material skinning phenomenon one to two months, it is fairly troublesome during the processing, and this position easily falls the damage, it needs expensive expense to glue the material to be fixed in the smoke chamber, the loss expense analysis of the cement manufacture enterprise's that causes of stopping the kiln one day: the cement raw line loss cost of 2500T/D is about 20 ten thousand; the cement raw line loss cost of 5000T/D is about 30 ten thousand. The labor consumption time and the cost are consumed, after the multi-element composite necking plate assembly is adopted, the situation is changed fundamentally, the phenomenon of skinning caused by frequent kiln shutdown is not needed, the time and the cost are saved, meanwhile, the labor is also saved, and the productivity is improved.
Disclosure of Invention
The invention aims to solve the technical problem in the prior art by using a multi-element composite necking plate at the necking part of a smoke chamber of a preheater of a cement kiln.
In order to achieve the purpose, the invention provides the following technical scheme: cement kiln preheater smoke chamber throat position is with compound throat board of many elements, including the mainboard, the mainboard top is equipped with the protective sheath hole, and protective sheath hole center is equipped with the installation fixed orifices, is equipped with the installation protective sheath on the installation fixed orifices, and mainboard left side middle limb is equipped with the baffle, is equipped with in the middle of the mainboard and strengthens fixed muscle, strengthens fixed muscle bottom and is equipped with connecting plate or tooth shape couple, and the connecting plate center is equipped with the bolted connection fixed orifices.
The invention is further improved in that: the mounting fixing hole, the mounting protective sleeve and the main board are fixed on the outer wall of the smoke chamber through bolts.
The invention is further improved in that: the tooth-shaped hook is used for installing the other necking plate.
The invention is further improved in that: the main board is connected with the mounting protective sleeve by bolts, the angle between the main board and the mounting protective sleeve is 90 degrees, the main board and the mounting protective sleeve are both made of multi-element composite stainless steel materials or multi-element composite ceramic materials, and the surfaces of the main board and the mounting protective sleeve are coated with flame retardant coatings.
The invention is further improved in that: the necking plate is S-shaped, L-shaped or I-shaped and is made of multi-element composite stainless steel materials or multi-element composite ceramic materials.
Compared with the prior art, the invention has the beneficial effects that:
1. the anti-skinning capability is good, because the temperature of the throat part of the smoke chamber is high and skinning is serious, skinning is hardly generated after the use, the skinning phenomenon does not need to be treated by frequently stopping the kiln, the cost is saved, and the production efficiency of a cement plant is improved;
2. the coating is corrosion-resistant, oxidation-resistant, heat-resistant, wear-resistant and anti-skinning, has long service life, does not need continuous replacement, saves cost and labor;
3. can accomplish the installation as required design specification and use, it is more convenient to produce.
