| Appendix No. 1 Technical specification for the design, manufacture and supply of a mixer with Z-shaped blades. |
|
| 1. Initial data | |
| Purpose of the equipment | Mixing the components that make up the product with each other into a homogeneous mass and subsequent unloading of the mass into the receiving hopper. |
| Mixer bowl volume | 700 liters |
| Mixer working volume | 400 liters (min) |
| Water temperature at the inlet to the mixer jacket | 20°C |
| Water temperature at the outlet of the mixer jacket | 26°C |
| Mixing time (excluding loading time of components, unloading, technological stops) | 60...120 minutes |
| The speed of rotation of the mixer blades faster slow |
0…48 rpm 0…24 rpm |
| Torque from the drive | on a slow-moving blade |
| The ratio of the rotation of the revolutions of the kneading shafts to each other | 1:2 |
| The gap between the blades and the mixer body | 1…4 mm |
| Mixer operating time, blade rotation time in and out | Provide a procedure for setting the rotation time |
| 2. Composition of the mixing product | |
| type density viscosity |
flammable liquid 0.718 g/cm3 0.243 centipoise |
| Ethyl spirit | |
| type density viscosity |
flammable liquid 789 g/cm3 1.19 centipoise |
| Cellulose Nitrate | |
| density | 1,58-1,65 g/cm3 |
| 3. Mixing process requirements |
| The product to be mixed must be homogeneous at all points of the mixer bowl. The product must have the same ratio of components. |
| The supply of flammable liquids and ethers should be carried out on the wall of the mixer bowl. The supply of flammable liquids and esters to the product is strictly prohibited. |
| 4. List of controlled parameters |
| - display of the coolant temperature at the inlet to the mixer cooling jacket and at the outlet of the jacket; - display of the product temperature inside the mixer; - control of the speed of rotation of the mixer blades; - temperature monitoring of bearing units; - current load monitoring of the electric motor; - control of the position of the mixer tank; - control of the closing/opening of the mixer lid; - control of the solvent volume supply (Supplier provide loadcells, customer install it on the 3 liquid storage tanks by themselves. PLC can set and control the 3 liquid feeding quantity automatically). |
| 4. Design requirements |
| 4.1. Enlarged mixer components - bowl with Z-shaped blades; - electromechanical rotation drive; - hydroelectric power station; - central control cabinet; - operator's control panel. |
| 4.2. General design requirements The complex of equipment should be divided into two categories depending on the degree of protection: Zone A. Equipment of conventional design for standard workshops. In Zone A there should be: - a drive station with an electric motor; - central control cabinet with touch panel and automation. Zone B. Explosion-proof equipment. In Zone B, there should be: - a mixer with all external equipment (sensors, distributors, etc.); - a hydroelectric station; - operator's control panel. Emergency stop buttons in explosion-proof design must be provided on the operator's control panel and in the immediate vicinity of the mixer. |
| 4.3. Bowl with Z-shaped blades. Design requirements. - should consist of a W-shaped bowl with a lid. The lid opening/closing drive is hydraulic, with position control; - the bowl and the mixer blades must be made of SS316L stainless steel; - the inner surface of the bowl and the surface of the mixer blades must be polished; - the bowl must have a water jacket to supply cooling water; - The coolant supply design of the Kneader reactor can body jacket is: when the can body rotates, the flexible sleeve (or hose) can contact the pneumatic valve and flowmeter; - It is necessary to install connecting flanges for supplying liquid and cooling water on the fixed parts of the Kneader reactor and connect them to the moving parts with flexible hoses; - fittings and valves for the supply of liquids in the amount of three pieces should be provided on the lid of the bowl. The valves must be controlled by pilot air; - there should be a blowout hatch on the lid, made according to the following sketch (the design of the knockout surface may change with subsequent agreement with the Customer): |
