Abstract:
Disclosed is a mixing apparatus of a large-scale carbon master batch production system. The mixing apparatus of a large-scale carbon master batch production system includes: a chamber into which materials is introduced; a hopper installed at an upper portion of the chamber, for introducing the materials into the chamber; a pair of rotors installed inside the chamber for pulverizing and mixing the materials introduced into the chamber; a driving motor connected to the rotor for rotating the rotor; a floating weight control unit installed at an upper portion of the chamber for pressing the materials introduced into the chamber through the hopper and pushing the pressed materials into the chamber, the floating weight control unit using different cylinders in a raising/lowering section and a dense section in which the materials are plasticized; and a discharge unit for discharging the materials mixed by the rotor to a lower side of the chamber.

PURPOSE: A carbon master batch manufacturing system, an environmentally-friendly fixed quantity plug type material transfer system thereof and a material transferring method thereof are provided to be capable of transferring a main raw material at a low speed, whereby the raw material is input in a kneading process with the physical property of the raw material well preserved, to prevent the flying of the raw material, and to measure the raw material to be filled in a hopper at an optimum dose, thereby reducing the loss rate of the raw material and defective products, and increasing productivity. CONSTITUTION: A carbon master batch manufacturing system comprises a hopper(20) supplied with a raw material; a pressure tank(110) using the compressed air to transfer the filled raw material into a feeding pipe; a material measuring unit(120) installed on the pressure tank for a raw material to be measured; a raw material storage tank(130) which stores the raw material transferred through the feeding pipe; a check section(140) installed in the raw material storage tank to check the transferred raw material; multiple pressure detection units(150) installed with a constant interval on the feeding pipe in order to sense the pressure differences of the inside of the feeding pipe; a compressed air injection unit(160) installed between the pressure detection units to inject the compressed air to solve the agglomeration phenomenon of the raw material; a control unit(170) receiving sensed data about the pressure differences from the pressure detection units and controlling the operation of the compressed air injection unit; and a mixer(151) installed on the lower part of the raw material storage tank to mix the transferred material in the raw material storage tank.

PURPOSE: A cooling control system and a temperature controlling method thereof are provided to reduce energy for improving the quality of a product and varying a producing process by controlling valves mounted by each cooling circulation line. CONSTITUTION: The input temperature of cooling water supplied to a mixer is measured(S11, S12). The temperature of the cooling water of each cooling circulation line circulating the inside of the mixer is measured. An average temperature is calculated by adding measured temperature of the cooling water(S13). An error value between the temperature of the cooling water measured at each cooling circulation line and the average temperature is calculated(S14, S16). Fuzzy theory is applied to the calculated error value. The position of a valve, which is mounted at each cooling circulation line, is calculated(S17). The corresponding valves are respectively controlled according to the calculated position of the valve.

Abstract:
PURPOSE: A floor material for a road for collecting an antiseptic solution and a manufacturing method thereof are provided to prevent environmental contamination caused by an antiseptic solution and safety accidents caused by a frozen road. CONSTITUTION: A floor material(100) for a road for collecting an antiseptic solution comprises an inclined portion(110) and an antiseptic solution discharge passage(120). The inclined portion has an incline for collecting an antiseptic solution falling down to the floor material to the center of the floor material and has first and second inclined plates(111,112). The antiseptic solution discharge passage is formed between the first and second inclined plates and discharges an antiseptic solution to an outlet formed on the end thereof.
