Description

Technical Field

[0001] This utility model relates to the field of screening and feeding technology, and in particular to a screening and feeding device for the production of boiler energy-saving and efficiency-enhancing agents. Background Technology

[0002] During boiler operation, scaling and oxygen corrosion are common problems. Scale buildup on the boiler's steam and water side tube walls not only affects the heat transfer efficiency of the boiler's heating surfaces and increases fuel consumption, but it is also a major cause of accidents such as boiler water-cooled wall tube rupture. Residual dissolved oxygen in the boiler feedwater is the root cause of pitting and even perforation in the boiler economizer and water-cooled walls. When the boiler continuously operates at a high heat load, the problems of residual oxygen corrosion and tube wall scaling will intensify. Adding energy-saving synergists to the boiler water can effectively prevent corrosion and scaling in the boiler. Boiler energy-saving synergists are mainly prepared by reacting isoascorbic acid with ethylene oxide. This synergist has significant deoxygenation, scale inhibition, corrosion inhibition, and defoaming properties. In the preparation of energy-saving synergists, the materials entering the production equipment need to be screened by a screening and feeding device before being fed into the production equipment.

[0003] Chinese Patent Publication No. CN211707377U discloses a feeding and screening device for a submerged arc furnace used in high-carbon ferrochrome smelting. The device includes a screening unit, a feed inlet, and a rotating rod. The feed inlet is fixedly installed at the top of the screening unit, and a rotating rod is installed inside the screening unit. A rotating plate is connected to one side of the rotating rod. The beneficial effects of this invention are: it has a compact structure, is easy to use, and is functionally practical. The second, third, and first screens are all detachable for easy removal and waste disposal. The support legs are connected by fixed rods, and the bottom of the support legs is fitted with rubber pads for stability, increasing friction and preventing the device from tipping over due to vibration during operation. The screening unit has a second and third screen with different mesh sizes, effectively screening out impurities. It features a simple structure, ease of use, and strong practicality. Furthermore, the device is environmentally friendly, does not pollute the environment, and does not harm human health, meeting societal needs.

[0004] When using traditional screening and feeding devices for boiler energy-saving and efficiency-enhancing agent production, the concentrated entry of materials into the screening box can easily lead to local blockages, thereby affecting the screening efficiency of the device. In addition, due to poor sealing at the material discharge point, material leakage may also occur. Utility Model Content
