Technical parameters and configuration of 110L internal mixer
Internal mixer:
1、 Mechanical function features:
2.1 Base: it is made by welding B-shaped channel steel and steel plate.
2.2 Internal mixing room: 28CrMnMo steel castings are prepared by heat treatment, and hardfacing wear-resistant German stellite hardness HRC60-62 is applied to the material contact surface.. The dovetail groove is machined and embedded with wear-resistant strip, with good sealing.
Cast iron heater is installed outside for heating the internal mixing chamber.
2.3 Mixing shaft: the main body is forged with CrMo alloy steel and quenched and tempered by heat treatment. The screw rib is cast with CrMo alloy steel wax mold, welded with stellite electrode, and then subject to overall heat treatment and tempering, and the overall surface is coated with wear-resistant alloy. The stirring edge meter is reasonable, the shape is round, and the stirring effect is more superior. Cooling water can be passed inside to make the cooling better.
2.4 Column: A3 steel plate is bent and welded with steel pipe. It has strong stability and stability. 2.5 Leakage proof device: mechanical shaft seal tightening system is adopted for the end face of the mixing shaft, with additional spacers, two sets of seals and double-layer leakage proof. There are plates on the side of the gland. Polymer resin fiber material is wear-resistant and not easy to break. The replacement is convenient and fast without affecting the production progress.
3. Pressurization system
3.1 Air cylinder: special cylinder. The speed and pressure can be adjusted according to the customer's convenience.
3.2 Compression cover: the main body is welded with 45 # cast steel and steel plate, and the stress is reasonable. The internal mixing surface is designed with uniform clearance of M. The internal design has an S-shaped flow channel, which can be heated by cooling water and steam. After heat treatment and tempering, the surface is plated with hard chromium, and the side is equipped with a leak proof device. The leakage proof sealing strip is made of high polymer resin fiber material, which is wear-resistant and not easy to break. The replacement is convenient and fast without affecting the production progress.
4. Unloading device
4.1 Structure composition: use the secondary enveloping turbine, worm structure or hydraulic turnover as the internal mixing chamber turnover unloading.
4.2 Turning angle: 110 ° (the maximum turning angle is 140 °).
4.3 Turning motor: Wannan motor.
4.4 Turning reducer: Guomao pin wheel cycloidal reducer is used.
4.5 Overturn control: two control and protection systems will not malfunction the overturning action, causing damage to the machine.
5. Transmission mechanism
5.1 Main motor: produced by Wannan Motor Co., Ltd., with the protection level of IP54, which is the highest level of protection in China at present, fully meeting the production needs.
5.2 Gear box: the gear is a hard tooth surface involute reducer, made of 20CrMnTi, hardened, carburized and ground, with a hardness of HRC57~62. The gear box is equipped with a cooling circulation system, which has low noise, high transmission torque and can withstand higher loads.
5.3 Belt pulley set: the main motor and gear box drive belt pulley have been finished with high safety factor to ensure that the transmission requirements are met.
