Description

Technical Field

[0001] The utility model relates to the technical field of alloy anti-scaling devices, in particular to a circulating water alloy anti-scaling device with a filtering function. Background Art

[0002] Industrial circulating water systems contain a large amount of minerals, such as calcium, magnesium, and iron. These minerals will form precipitates under certain conditions and adhere to the inner wall of the pipe. Microorganisms in the water will also multiply in large numbers under suitable conditions to form biofilms, which will then form bioscaling. At the same time, changes in water temperature will cause changes in the solubility of dissolved substances in the water, which will increase the adhesion of minerals in the pipes and accelerate scaling. The adhesion of scale will reduce the heat transfer efficiency of the equipment, affect the normal use of the equipment, and even cause equipment failure in severe cases.

[0003] At present, the anti-scaling methods for circulating water systems at home and abroad are mainly divided into chemical methods, physical methods and process methods. The anti-scaling mechanism of the chemical method is to use certain characteristics of chemical anti-scaling agents to prevent the formation of scale; the anti-scaling mechanism of the physical method is to use the functions of certain physical instruments and equipment to inhibit the formation of scale; the process method is to destroy or reduce the chance of scale formation by changing or controlling certain operating process conditions. There are many types of chemical anti-scaling agents, and although they are widely used, their limitations are also obvious. The physical method relies on the physical effects of magnetic fields, sound fields, ultrasonic waves, etc. The equipment is expensive, the investment is large, and the effect is easily affected by water quality.

[0004] Therefore, we designed an alloy anti-scaling device combined with a pre-filtration device to solve the problem of circulating water anti-scaling. Utility Model Content

DETAILED DESCRIPTION

[0015] The utility model is further described below with reference to the accompanying drawings and embodiments. Embodiment 1

[0016] Reference Figure 1-2 As shown, a circulating water alloy anti-scaling device with filtering function includes a filter and an anti-scaling device, and the filter is installed on the front side of the anti-scaling device.

[0017] The anti-scaling device includes a shell 1 and a joint 2 connected by a flange. Six groups of anti-scaling alloy rings 3 are arranged side by side in front and back in the shell 1. The anti-scaling alloy ring 3 groups include two anti-scaling alloy rings 3 symmetrically arranged in front and back. The anti-scaling alloy ring 3 is trumpet-shaped and has a plurality of flow holes 301 opened on the anti-scaling alloy ring 3.

[0018] More specifically, the anti-scaling alloy ring 3 contains Cu, Fe, Ni, Zn, Ag, Se, Sb, Bi and rare earth elements RE.

[0019] The filter comprises a cylindrical filter screen 8 and an inlet pipe 4, a cylinder body 5 and an end seat 10 which are sequentially connected from top to bottom; a water outlet pipe 7 is arranged on one side of the cylinder body 5; limiting rings 6 which are adapted to the cylindrical filter screen 8 are arranged on the inner walls of the upper and lower ends of the cylinder body 5; the cylindrical filter screen 8 is inserted into the cylinder body 5, and its outer wall contacts the inner walls of the two limiting rings 6; the annulus between the cylindrical filter screen 8 and the cylinder body 5 is a post-filtration cavity 9; the inner diameter of the end seat 10 is equal to the inner diameter of the cylindrical filter screen 8, and a sewage discharge pipe 11 is arranged on one side thereof, and a scraping component which probes into the inner cavity of the cylindrical filter screen 8 is arranged inside the end seat 10.

[0020] The scraping assembly includes a spiral scraper 12 and a central shaft 13. The spiral scraper 12 is fixedly sleeved on the central shaft 13, and its outer edge contacts the inner wall of the cylindrical filter 8 and the inner wall of the end seat 10; the lower end of the central shaft 13 passes through the bottom plate of the end seat 10 and is connected to a crank 14.

[0021] When in use, the device is connected to a circulating water system, and the circulating water enters the cylinder 5 through the water inlet pipe 4, is filtered out by the cylindrical filter 8 to remove large particles of impurities, and is collected in the post-filter chamber 9, and then enters the anti-scaling device through the water outlet pipe 7; the circulating water is in full contact with the inside and outside of a number of anti-scaling alloy rings 3 in the shell 1, and the anti-scaling alloy rings 3 release metal cations, a part of which will preferentially combine with scaling anions, so that the calcium and magnesium particles in the water cannot combine with the scaling anions, slowing down the nucleation rate and crystal growth rate of scale crystals, thereby preventing scale precipitation; moreover, some cations can change the solubility and crystal morphology of scale crystals, so that they can become soft scale and be quickly carried away by the water flow, thereby playing an anti-scaling and anti-scaling role in the circulating water system.

[0022] After filtering for a period of time, a large number of large particles of impurities will adhere to the inner wall of the cylindrical filter 8, affecting its filtering efficiency. At this time, the circulating water system is shut down and the sewage pipe 11 is opened, and then the crank 14 is turned to drive the spiral scraper 12 to scrape off the large particles of impurities on the inner wall of the cylindrical filter 8 and spirally transport them into the end seat 10, and then discharged outward from the sewage pipe 11.

[0023] This alloy anti-scaling device has the outstanding advantages of no chemical reagent addition, no pollution, high efficiency, long validity period, no magnetism or electricity, no (less) maintenance, wide application range, low cost, etc. It is suitable for circulating water anti-scaling applications and has excellent anti-scaling effect on circulating water systems; the filter can prevent large particles of impurities in the circulating water from clogging the anti-scaling device, play a role in protecting the alloy anti-scaling device, and extend the operating life of the alloy anti-scaling device.

[0024] The present invention is not limited to the above-mentioned implementation modes. Within the knowledge scope of those skilled in the art, various changes can be made without departing from the purpose of the present invention. The changed contents still belong to the protection scope of the present invention.
