Description

Technical Field

[0001] This utility model belongs to the technical field of cooling water treatment equipment, specifically an electrochemically treated circulating cooling water scraper. Background Technology

[0002] The circulating cooling water in the energy and chemical circular economy park is used for heat exchange and cooling of industrial equipment. The circulating cooling water system is a major water consumer in industry, accounting for more than 50% of the factory's water consumption. Therefore, increasing the concentration ratio of the circulating cooling water and reducing wastewater discharge is crucial for water conservation in the park. The circulating cooling water contains high concentrations of corrosive and precipitating components, which easily cause corrosion and scaling in heat exchange equipment. Developing circulating cooling water treatment technologies capable of removing hardness and chlorine, sterilizing, reducing water consumption, and increasing the concentration ratio is essential for saving water resources and solving the problems of corrosion and scaling in heat exchange equipment.

[0003] Traditional circulating cooling water treatment technologies mainly include chemical methods, biochemical treatment technologies, and membrane separation methods. Chemical methods are simple and efficient, but the high cost of using chemical agents makes them unaffordable for many enterprises. Poor microbial tolerance, poor treatment effects, and limited applicability have consistently limited the application of biochemical treatment technologies. Membrane separation methods suffer from high costs and membrane scaling issues. Traditional circulating cooling water treatment technologies are no longer suitable for today's highly intensive and interconnected energy and chemical circular economy parks.

[0004] Therefore, for electrochemical treatment circulating cooling water devices, the cooling water is processed by doping metal oxide electrodes and metal sulfide electrodes with electro-controlled ion exchange materials to obtain electro-controlled ion exchange modified cathodes and anodes. However, the cathodes and anodes of this device will accumulate scale after long-term use and need to be cleaned frequently. Summary of the Invention

[0005] This invention provides a scraper for electrochemically treated circulating cooling water to solve the problem of cleaning scale on the cathode and anode in an electrochemically treated circulating cooling water device.

[0017] Short scraper II, two of which are respectively mounted on two short scraper holders;

[0018] A long scraper, which is mounted on a long scraper holder.

[0039] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0040] like Figure 1 , 4 As shown, an electrochemically treated circulating cooling water scraper includes:

[0041] Hydraulic cylinder 1;

[0042] Beam 2, the middle part of which is fixed to hydraulic cylinder 1 and moves up and down with hydraulic cylinder 1;

[0043] The outer scraper assembly 3 consists of two sets, symmetrically arranged at the left and right ends of the beam body 2.

[0044] The inner scraper assembly 4 consists of 2n units, which are symmetrically installed on the front and rear sides of the beam body 2.

[0045] Specifically, the beam 2 is driven by the hydraulic cylinder 1 to move up and down. During the lifting and lowering process, the outer scraper assembly 3 and the inner scraper assembly 4 respectively scrape the surfaces of multiple sets of metal oxide electrodes and metal sulfide electrodes arranged side by side. The metal oxide electrodes and metal sulfide electrodes are vertically arranged plate-shaped structures.

[0046] like Figure 2 , 3 As shown, the inner scraper assembly 4 includes:

[0047] Tool holder 4.1, two tool holders 4.1 are arranged side by side;

[0048] Two short scrapers I4.2 are provided and are respectively installed on two blade holders 4.1, with the blades of the short scrapers I4.2 facing outward.

[0049] Specifically, in an inner scraper assembly 4, two short scrapers I4.2 are symmetrically arranged. The end of the blade holder 4.1 is connected and fixed to the beam 2, while the short scrapers I4.2 are mounted on the blade holder 4.1.

[0050] like Figure 1 , 2 As shown, the outer scraper assembly 3 includes:

[0051] A long tool holder 3.1 is provided on the outer side;

[0052] Short tool holder 3.2, two sets of short tool holder 3.2 are provided, the two sets of short tool holder 3.2 are symmetrically arranged on the front and rear sides of the beam 2, and the two sets of short tool holder 3.2 are on the same straight line, and the two sets of short tool holder 3.2 are arranged inside the long tool holder 3.1;

[0053] Two short scrapers II3.3 are provided, each mounted on one of the two short scraper holders 3.3;

[0054] A long scraper 3.4 is mounted on a long scraper holder 3.1.

[0055] Specifically, the outer scraper assembly 3 is the outermost scraper assembly at both ends of the beam 2. Since the long blade holder 3.1 and long scraper 3.4 on its outer side cannot be fixed to the beam 2, they are set as a long blade holder 3.1 and long scraper 3.4 on the outer side. It is an integral structure and does not need to be fixed to the beam 2.

[0056] Meanwhile, the two short blade holders 3.2 and the long blade holder 3.1 are connected as one unit by connecting beam II 3.5, and the short blade holders 3.2 and the long blade holder 3.1 are connected by upper and lower clamping plates to make them stable as a whole.

[0059] The blade 4.21 is a cuboid structure that can be inserted into a long rectangular tube.

[0060] The blade 4.22 is located on one side of the blade body 4.21 and passes through the cutting edge on the outside of the long rectangular tube.

[0061] Specifically, the two tool holders 4.1 consist of two sets of elongated square tubes, with the cutting edges of both sets of tubes facing outwards. This allows the cutting edge 4.22 to extend from the cutting edge, thus performing scraping operations on the metal oxide and metal sulfide electrodes. Since the metal oxide and metal sulfide electrodes are vertically arranged plate-like structures, the cutting edge 4.22 can treat the surface grooves of the plate-like structures during its up-and-down movement.

[0062] The short blade holder 3.2 has the same structure and dimensions as the blade holder 4.1. The short blade holder 3.2 serves as the structure of the outer scraper assembly 3, and its end is fixed to the beam 2.

[0063] The long tool holder 3.1 and the tool holder 4.1 have the same structure, both being long rectangular tubes. The length of the long tool holder 3.1 is twice the length of the short tool holder 3.2 plus the width of the beam 2.

[0064] The short scraper II3.3 has the same structure and dimensions as the short scraper I4.2;

[0065] The long scraper 3.4 has the same structure as the short scraper I4.2, and its length is twice the length of the blade 4.21 plus the width of the beam 2.

[0066] Specifically, the two tool holders 4.1 are connected as a whole by a connecting beam I4.3. Each of the two tool holders 4.1 is provided with a clamping plate 7 at the top and bottom for connecting the tool holders 4.1 as a whole.

[0067] An annular protrusion 6 is provided on the lower middle side of the beam 2, and the annular protrusion 6 is used to connect and install the output end of the hydraulic cylinder 1.

[0068] like Figure 5 , 6 As shown, in the electrochemical treatment circulating cooling water device, the anode and its mounting structure are inserted into the cathode and its mounting structure, wherein the cathode and anode are arranged crosswise, and an electrochemical treatment circulating cooling water scraper is installed at the bottom of the cathode and its mounting structure. Driven by the hydraulic cylinder 1, the electrochemical treatment circulating cooling water scraper performs a scraping operation on the scale on the cathode and anode.
