It is convenient, can improving production efficiency.Meanwhile present invention also offers a kind of screen cloth for catalyst preparation roaster and its processing
Technique.
In order to solve the above technical problems, the technical solution adopted by the present invention is：
A kind of roaster for catalyst preparation, including：Spray chamber, the firing chamber connected with the spray chamber and institute
State the cooling chamber of firing chamber's connection and the screen cloth between the firing chamber and the cooling chamber.
Shower nozzle is provided with the top of the spray chamber；Heating coil is respectively equipped with the top and bottom of the firing chamber；The cooling
Blower fan is respectively equipped with the top and bottom of room.
A kind of screen cloth for catalyst preparation roaster, including inner surface set slotted fixed frame, are arranged in groove
Screen body and the both sides of the fixed frame and the fastening bolt being in contact with the end face of the screen body are threadedly connected to,
Hollow out handle is provided with above the screen body.
A kind of processing technology of screen cloth for catalyst preparation roaster, step are as follows：
1., the processing of fixed frame
Fixed frame is taken the shape of the letter U, and using stainless steel materials punch forming, notch is opened up in the interior survey face of fixed frame；
2., the processing of screen body
Screen body is made up of the square stainless steel materials of a block length, makes its surface hollow-out into small one by one using diel
Hole, rectangular hollow out handle together is then opened up at the top of screen body；
3., screen body surface coating processing
The mesh position of screen body is sprayed into one layer of overcoat, then dried；
The preparation method of overcoat is：By 15 parts of urethane acrylate, 10 parts of carboxy acrylic ester, 5 parts of ethylene glycol, male
Red 4 parts of phenol is well mixed with 3 parts of prothioconazoles, crosses 50 mesh sieves and produces；
4., assembling
The notch of screen body self-retaining inframe side is loaded, then fastened screen body and fixed frame by bolt.
Advantage for present invention is with effect：
1), the roaster for catalyst preparation, including：Spray chamber, the firing chamber connected with the spray chamber, with it is described
The cooling chamber of firing chamber's connection and the screen cloth between the firing chamber and the cooling chamber；The screen cloth includes inner surface
If slotted fixed frame, the screen body being arranged in the groove and be threadedly connected to the fixed frame both sides and with it is described
The fastening bolt that the end face of screen body is in contact；When screen cloth, which blocks needs, to be changed, fastening bolt only need to be unscrewed, will be sieved
Net body is extracted out from the groove of fixed frame, the screen body changed afterwards after new screen body or cleaning, and screws fastening spiral shell
Bolt, the replacing of screen cloth is more convenient, can improving production efficiency.
2) a kind of, screen cloth and its processing technology for catalyst preparation roaster, product structure design is more novel, adds
Work technique uses sprays overcoat process to screen body, the antioxygenic property of screen cloth is significantly improved, makes so as to extend
Use the life-span.
