Introduction

This Pre-stressed Concrete Spun Pole Production Line is designed in accordance with annual production capacity of 36,000pcs various medium-sized cone pre-stressed steel concrete poles.
As far back as the 1930s, the People’s Republic of China used armored concrete pole. With the rapid development of power industry, the production and use of concrete pole has developed tremendously thereupon.
Pre-stressed concrete pole develops rapidly because of much superiority. Compared with common concrete pole, its advantage is as follows:
Economizing steel in a large amount, about 30%~70% (adopting cold drawing can economize 30%~60%; in case of steel wire of high strength, economize 40%~69%);
Crack resistance is improved by 3~5 times;
Steel performance can be improved by 1~3 times;
Reduction of cost (adopting cold drawn wire can economize 25%~40%; in case of steel wire of high strength, economize12%~21%);
Good endurance can delay the appearance and expansion of cracks;
Protecting the environment that mankind depends on for existence, and reducing deforestation.
Pre-stressed concrete poles are strictly in accordance with two standards: GB396-94 Annular Armored Concrete Pole and GB4623-94 Annular Pre-stressed Concrete Pole of the People’s Republic of China.

Overview

Double-effect falling film vacuum concentrating device uses mainly the secondary steam produced by the dryer, without consuming new heating steam. Fish protein produced by the previous working procedure is concentrated to concentration of about 30% in it under the condition of vacuum and low temperature, and then is added in the dryer to make finished fish meal or else made into other product for sale.
Double-effect falling film vacuum concentrating device, which utilize waste steam for heating, economizes on energy and can effectively resolve the environment pollution problems of waste water and fluid during the production of fish meal.
