Abstract

The invention relates to a feeding-controllable water absorbing resin particle production system comprising a reaction kettle, a polymerization plant, a colloid mill, a dryer, a material pool, a separator, a screening machine, a grinder and a stock bin, the reaction kettle comprises a kettle body and a feeding-controllable feeding mechanism, the feeding-controllable feeding mechanism comprises sealing covers, feeding tubes, hydraulic control valves, feed tanks, mounting racks, material conveying pipes, material pumping pumps and raw material barrels, two feeding mouths of the kettle body of the reaction kettle are provided with the sealing covers, one ends of the feeding tubes pass through the sealing covers to extend into the kettle body, the other ends of the feeding tubes are installed on the bottom of the feed tanks, the hydraulic control valves are installed on the feeding tubes, the feed tanks are arranged on the mounting racks, the mounting racks are symmetrically arranged on both sides of a mixing mechanism in the kettle body, and the feed tanks are connected, by the material conveying pipes, with the raw material barrels connected with the material pumping pumps. The feeding-controllable water absorbing resin particle production system has the advantages of scientific and reasonable structure design, low labor intensity, saving manpower, controllable material feeding, satisfaction of the technology demand, safety and reliability, and high production efficiency.

Description

technical field [0001] The invention relates to a production line, in particular to a water-absorbing resin particle production system with controllable feeding. Background technique [0002] Water-absorbing resin is a new type of polymer material, which can absorb hundreds or even thousands of times its own weight in water, and has the characteristics of non-toxic, harmless, non-polluting, strong water absorption capacity, and high water retention capacity. In order to meet the requirements for the use of water-absorbing resin in different fields, it is necessary to crush the formed bulk water-absorbing resin into the required particle size during production. The processing technology of water-absorbent resin particles generally needs to go through processes such as mixing, polymerization, grinding, drying, separation, screening and crushing. The continuous production line of water-absorbent resin particles is composed of a reactor, a polymerization device, a colloid mill,...

AI Technical Summary

Problems solved by technology

Due to the large volume of the reactor, workers need to lift the raw materials to the vicinity of the feeding port of the reactor with the aid of ladders before manually feeding, which is labor-intensive and labor-intensive.

Moreover, acrylic acid solution and sodium hydroxide solution need to be fed according to a certain feeding frequency. Manual operation not only has the disadvantage of uncontrollable feeding amount, but also has low feeding frequency precision, which cannot meet the process requirements.

In addition, acrylic acid solution is a liquid with a pungent smell, and sodium hydroxide will also have an astringent taste after being dissolved in water. Therefore, if it is directly injected manually, it will also pose a threat to the health of workers.
