Description

Technical Field

[0001] This utility model relates to the field of chlorination furnace technology, specifically to a chlorination furnace water cooling and circulation device for producing ferric chloride. Background Technology

[0002] The water cooling circulation system of the ferric chloride chlorination furnace is a key system for controlling and maintaining the furnace temperature. During the production of ferric chloride, the chemical reaction is usually exothermic, requiring effective cooling measures to maintain appropriate reaction conditions and prevent overheating that could lead to safety risks or product quality problems. Water or an aqueous solution containing antifreeze is typically used as the cooling medium, and a water pump delivers the coolant to the areas requiring cooling.

[0003] Existing chlorination furnace water cooling circulation systems often face a significant problem when extracting and circulating the cooling liquid from the chlorination furnace: reaction residues generated during processing, or uncleaned deposits on the furnace's inner walls, cause these particulate or flocculent impurities to enter the water cooling circulation system during discharge. This impure coolant not only affects the system's heat exchange efficiency but also easily causes blockages or wear in pipes, pumps, and filters, significantly increasing the workload of the chlorination furnace water cooling circulation system and making it inconvenient to use. Utility Model Content

[0004] The purpose of this invention is to provide a chlorination furnace water cooling circulation device for producing ferric chloride, to solve the problem mentioned in the background art where existing chlorination furnace water cooling circulation devices often have particulate or flocculent impurities carried by the coolant during circulation due to residues inside the chlorination furnace or impurities entering the device. These impurities easily clog pipes, wear down equipment, affect heat exchange efficiency, increase the burden on the device, and are detrimental to stable operation and daily maintenance.

[0009] Furthermore, a motor is fixedly connected to the inner cavity of the fixing block, and the output shaft of the motor is fixedly connected to the bottom end of the threaded rod.

[0010] Furthermore, a fixed plate is fixedly connected to the inner cavity of the running rod, and springs are connected to both the left and right sides of the fixed plate. A guide rod is fixedly connected to one end of the spring, and the surface of the guide rod is slidably connected to the inner cavity of the running rod.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] The present invention will be further described below with reference to the embodiments.

[0027] Example: A chlorination furnace water cooling and circulation device for producing ferric chloride, such as... Figures 1-7As shown, the furnace includes a chlorination furnace body 1. A drainage pipe 2 is connected to the surface of the chlorination furnace body 1, with one end extending to the bottom of the inner cavity of the chlorination furnace body 1 to facilitate faster liquid discharge and cooling. A water cooling circulation device body 3, in contact with the ground, is installed on the left side of the chlorination furnace body 1. Metered iron filings are fed into the furnace from the top of the chlorination furnace body 1, and the furnace cover is sealed. Chlorine gas enters from the bottom of the chlorination furnace body 1 through a chlorine gas inlet pipe. The iron filings and chlorine gas undergo a chlorination reaction at high temperature, releasing heat. The temperature inside the chlorination furnace is controlled at ≤650℃ by a cooling circulation water system. After chlorination, the iron filings generate ferric chloride vapor. The chlorine gas flow rate is adjusted according to the amount of iron filings fed and the change in the outlet temperature of the chlorination furnace body 1 to control the chlorination reaction rate. The reaction time for each batch is approximately 3 hours, varying slightly depending on the amount of iron fed into the furnace and the chlorine gas pressure. Besides maintaining the necessary reaction temperature of 650℃, excess heat released by the reaction is carried away by the cooling water flowing in the jacket of the chlorination furnace body 1. The ferric chloride vapor generated by the reaction is sequentially drawn into two series-connected traps through the herringbone connecting pipe at the outlet of the chlorination furnace. It is indirectly cooled and condensed into solid anhydrous ferric chloride by the cooling water flowing in the jacket of the trap. After the chlorination reaction stops, the solid ferric chloride powder is cleaned and put into the storage hopper for natural cooling. The water inlet end of the water cooling circulation device body 3 and one end of the drainage pipe 2 are jointly provided with an interception component 4. The interception component 4 includes a connecting box 41 and two operating rods 410. The connecting box 41 is connected to the drainage pipe 2 and the water inlet end of the water cooling circulation device body 3 through flanges.

[0028] like Figures 2-7 As shown, a cleaning plate 414 is slidably connected to the surface of the operating rod 410, and the surfaces of the two operating rods 410 are fixedly connected to each other. A filter screen plate 415 is fixedly connected to the inner cavity of the connecting box 41. Fixing blocks 42 are fixedly connected to the left and right sides of the surface of the connecting box 41. A positioning frame 43 is fixedly connected to the top of the fixing block 42. A threaded rod 44 and a sliding rod 45 are respectively connected to the inner cavity of the positioning frame 43. The outer surface of the threaded rod 44 is provided with external threads. A moving plate 46 is movably connected to the surfaces of the threaded rod 44 and the sliding rod 45. The area of ​​the moving plate 46 in contact with the threaded rod 44 is provided with a matching internal thread, and the surface of the moving plate 46 slides against the inner cavity of the positioning frame 43. The moving plate 46 is connected to push rods 48 on both the left and right sides of its bottom. The bottom end of the push rod 48 extends into the inner cavity of the connecting box 41 and is fixedly connected to the surface of the running rod 410. The area where the push rod 48 and the connecting box 41 penetrate through is sealed. The inner cavity of the fixed block 42 is fixedly connected to a motor 47. The output shaft of the motor 47 is fixedly connected to the bottom end of the threaded rod 44. The inner cavity of the running rod 410 is fixedly connected to a fixed plate 411. The left and right sides of the fixed plate 411 are connected to springs 412. One end of the spring 412 is fixedly connected to a guide rod 413, and the surface of the guide rod 413 is slidably connected to the inner cavity of the running rod 410.

[0029] like Figures 3-7 As shown, one end of the guide rod 413 extends through to the outside of the running rod 410 and is fixedly connected to a cleaning plate 414. The surface of the cleaning plate 414 is in contact with the surface of the filter screen plate 415, while the surface of the cleaning plate 414 and the surface of the running rod 410 are slidably connected to each other. The water outlet of the water cooling circulation device body 3 is connected to a water inlet pipe 5. One end of the water inlet pipe 5 extends through to the inner cavity of the chlorination furnace body 1. The surface of the connecting box 41 is connected to a chip discharge pipe 49. A valve is installed on the surface of the chip discharge pipe 49 to facilitate the collection of waste chips after cleaning the filter screen plate 415.

[0030] Specifically, when the cooling liquid in the chlorination furnace body 1 needs to be circulated and cooled, the water cooling circulation device body 3 is activated to draw the liquid into the drain pipe 2, and then the drain pipe 2 transports the liquid to the connection box 41. During this process, when the cooling liquid passes through the filter screen 415, the impurities it carries are effectively intercepted, thereby preventing impurities from entering the water cooling circulation device body 3 and causing blockage or equipment damage.

[0031] When the filter screen 415 has been used for a long time and a lot of impurities have accumulated on its surface, the motor 47 can be started, which drives the threaded rod 44 to rotate. Through the threaded transmission principle, the threaded rod 44 pushes the moving plate 46 to move up and down, and the moving plate 46 drives the push rod 48 and the running rod 410 to move synchronously. The running rod 410 further drives the guide rod 413 and the cleaning plate 414 to move up and down, realizing the automatic cleaning operation of the filter screen 415, preventing impurities from clogging the filter screen, and ensuring smooth liquid flow.

[0032] In addition, during the up-and-down movement of the operating rod 410, the spring 412 drives the guide rod 413 and the cleaning plate 414 to produce lateral displacement, so that they can move closely against the inner wall of the connecting box 41, thereby achieving comprehensive and uniform cleaning of the filter screen plate 415, improving the stability and maintenance efficiency of the device, and facilitating long-term use.

[0033] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
