Structure This unit is made up of high-speed mixer,cooling mixer (these two are made up Page 5 of 11

6 of driving, main body, pot cover, drive part, disappearing end bumper, material unload door), foundation, electric cabinet and etc. The main body is welded by the stainless steel, the interior surface is extremely hard and smooth, have such characteristics as wear-resisting, corrosion-resistant, difficult sticking, etc. There is asbestos heat preservation wrapped outside the main body. The cold drifts along one pot of walls and cools and inserts one; reach the result of cooling through cooling circulation. The pot cover was cast by the aluminum alloy, the interior surface underwent the finish machining and polishing, after it is jacked by air cylinder. There are ventilate holes and holes on the cover, which are convenient for adding resin, plasticizer and stabilizer into the mixer, you can arrange it according to your requirements. The pot cover revolves easily and expediently; please do not overexert the pot cover in the case of damaging the sealing bar. In order to avoid body damage when the pot cover is opened, the electrical cabinet controls the current turn off so that the motor will not work. This is the safe measure. Hot mixing baffle is used for Strengthen the effect of mixing. There have each temperature thermocouple in the heating and cooling machine. The temperature of the material can be reflected by temperature-controlled form; Used in the material appears automatic allying at the same time. Stirring arm is urged by motor with the trigonometry. The motor is an alternating-current motor; it can realize the low high speed by pushing low and high-speed button. But must notice: While wanting to run at a high speed, make the motor start at a low speed first, and then change to a high speed. The main shaft is supported and operated by 316, 314 bearings. The main shaft has three stirring arm. They make the material on one hand move along one pot of walls along rotating clockwise rotation, at the same time upper and lower circulation are rotated. With effect of baffle, the mixing result is better. Because of material being high-speed rotating, so the frictional heat between the materials, and the frictional heat between material and leaf is very big, making the temperature of the material rise rapidly, and making the resin easy to absorb the plasticizer. Stirring arm is made of stainless steel, pass machine work, wear resisting corrosion-resistant. Running part of cooling mixer is moderate by motor driving main shaft, let stirring arm rotate, cool the hot thoughtlessly material to mix. The base was welded by stencil plate, angle steel, channel, there were four pieces of jack-up rings on both sides, it is extremely convenient to hoist, Is it regulate bolt to have, Page 6 of 11

7 adjustable transmission trigonometry bring elasticity, bottoms have eight foundation bolt hole, what the apron can change the trigonometry and take and the installing machine seat is regular to open and maintain. Discharging part of material is made of aluminum alloy; it is equipped with one and unloaded the material door pneumatically, linked sharply by the air cylinder and material door first line type. It is reliable to compress tightly, the sealing is good, and it is flexible to open. Use MPa air compressor (by user's apolegamy). Unload material way can warm to automatically control material with pan have or with manual to control two way is it is it unload material door open, close to control to come button. 4. Installation and maintenance 1) Installation Mixer and electric cabinet will be installed on the concrete floor or firm steel frame. Adjust the plane place; fix it with eight anchor bolts. Cooling mixer adopt cooling water through the container entresol. Electrical wires and the air supply wires are covered with pipes. The install dimension and the fixed bolt holes can consult the install ground plot. 2) Usage and maintenance Check carefully the electrical supply air supply whether they are the same as the machine before running the machine. Installed every part completely, inspect the circuit as the circuit diagram carefully, make sure the lubricant has been added, and clear the pickling oil anyplace on the machine. 1) Adjust filter voltage regulator, make the air pressure at the range of 4-7bar.Start the machine when pressure exceed 4bar, turn on the cooling water, and adjust the water runoff to make sure that water pressure not exceed 1bar. Excessive water will increase the pressure of the container entresol, so keep water straightway in the entresol. The water must be filtered, and the chloride content not exceeds 80mg/L. 2) Turn off the emergency stop button, and make the switch at the hand motion place. 3) Loose the reinforce screw nut on the heat pot cover, turn on the on/off button, and the heat pot cover can up and down flexibly. 4) Open the pot cover, inspect whether the screw nut which reinforce the Page 7 of 11

When all above functions are normally, the mixer can run. The heat mixing must start with low speed without load, and then run high speed and without load. The turning direction of the heat mixing must be the same as the sign on the container, run about 10min without load, and then inspect the compressed air system. Once the machine has been used, please clear the inner wall and stirring arm if no use a short time; spread pickling oil on the machine if no use long time. Requirement of all lubrication points: Main shaft of the mixer: 4 sodium base grease (GB492-89) once a day Make an overhaul once half a year, change obturator anyplace. Inspect the circuit and the elements. 1) Lubricate the machine on schedule. 2) Clearing maintaining repairing: Act on power off. 48 hours: clear the outer equipment coarsely; open the heating mixer s pot cover; clear the inner wall and unload door; inspect the oil level of the air elements; inspect the air pressure hours: disassemble the agitation shaft and fan, clear the inner wall and make sure not damage to the machine when installing and clearing. 3) Disposals to the long no use: (1) Turn off the main power supply (2) Turn off the air supply (3) Turn off the cooling water (4) Draw off the water in the container entresol Install the heating mixer s agitation fans in turn, and fix them with hexagonal bolt hours (a month): Thermocouple: change if ruined hours: Disassemble the bearing only when it ruined badly (big noise, overheat), change the ruined part, and lubricate it when installed. Bearing of heating mixer: Page 8 of 11

9 Before disassemble the bearing, please loose the motor adjusting plate, remove the V strap and agitation fans, and then loose the belt wheel. So we can take off the below bearing, and the bearing upside can be taken off from the casing by taking up the shaft. 5. Safety regulations All junction boxes electric apparatus door of control panel cannot open only when repairing. Before opening, must turn off the electricity and show a sign that don t turn on the power switch.
