Description

Technical Field

[0001] This utility model belongs to the field of silicon steel processing, specifically relating to a raw material preparation and reaction device for silicon steel rolling fluid. Background Technology

[0002] The silicon steel rolling fluid raw material preparation and reaction device is a special equipment used to prepare the rolling fluid, process lubrication and cooling medium required in the production of cold-rolled silicon steel sheets. Its core function is to mix base oil, additives and water in a specific ratio and form a stable emulsion or solution through chemical reaction and physical homogenization treatment.

[0003] In common commercial reactors, the mixing of raw materials for silicon steel rolling slurry typically employs a single stirring structure. The stirring paddle is usually installed in the middle or upper part of the rotating shaft. This layout results in insufficient mixing of raw materials located at the bottom of the device, easily creating dead zones and leading to uneven mixing. This affects the performance and quality of the silicon steel rolling slurry. During the mixing process, due to the viscosity or other properties of the raw materials, some inevitably adhere to the inner wall of the reactor. The long-term accumulation of these adhered materials not only wastes raw materials but may also affect subsequent reactions and even reduce the purity of the reaction products. However, common reactors often lack an effective scraping structure, requiring regular manual cleaning of the inner wall. This not only increases the labor intensity of operators but may also affect the continuity of production due to untimely or incomplete cleaning. Utility Model Content

[0004] To overcome the problems of limited stirring effect of a single stirring paddle and raw material adhesion to the inner wall of the reaction device when using silicon steel rolling slurry raw material preparation and reaction device, a new type of silicon steel rolling slurry raw material preparation and reaction device is proposed.

[0005] The technical solution of this utility model is as follows: a silicon steel rolling liquid raw material preparation and reaction device, including a reaction mechanism and a feeding device. The reaction mechanism includes an inner cylinder. The feeding device is installed at the upper end of the reaction mechanism and includes a fixed cover. The fixed cover is fixedly connected to the upper end of the inner cylinder. The discharge device is installed at the lower end of the reaction mechanism and includes a cover. The cover is fixedly connected to the lower end of the inner cylinder. A stirring mechanism is installed inside the reaction mechanism. The stirring mechanism includes bearings. The lower center of the fixed cover and the upper center of the cover are fixedly connected to corresponding bearings. The inner rings of the bearings are fixedly connected to a rotating shaft. The outer wall of the rotating shaft is fixedly connected to a scraper and a stirring blade distributed vertically. The scraper blade of the scraper blade is in contact with the inner wall of the inner cylinder. The upper and lower ends of the scraper blade are flush with the upper and lower ends of the inner cylinder. A servo motor is installed at the upper end of the fixed cover. The output end of the servo motor is connected to the rotating shaft.

[0006] Furthermore, an outer cylinder is fixed to the outer wall of the inner cylinder, and a spirally wound heating tube is installed between the inner cylinder and the outer cylinder.

[0007] Furthermore, the feeding device also includes feeding pipes, with three equally spaced feeding pipes fixed to the upper end of the fixed cover, and diffusers fixed to the inner walls of each feeding pipe.

[0008] Furthermore, a corrugated pipe is fixedly connected to the upper opening of the feed pipe, and the feed pipe is connected to the discharge port of the raw material barrel through the corrugated pipe.

[0009] Furthermore, the discharge device also includes discharge pipes. Two symmetrically distributed discharge pipes are fixed to the lower end of the cover. Valves are installed on the discharge pipes, and a mesh cover is threaded onto the lower end of the discharge pipe.

[0010] Furthermore, a support device is installed at the lower end of the reaction mechanism. The support device includes a support frame, and a support ring is fixed to the outer wall of the outer cylinder.

[0011] Furthermore, the upper end of the support frame is fixed with the fixed ends of several shock absorbers, the output ends of the shock absorbers are fixed together with the lower end of the support ring, and a rubber ring is fixed at the joint between the support frame and the outer cylinder.

[0012] The beneficial effects of this utility model are as follows: The output end of the servo motor can drive the rotating shaft to rotate, thereby driving the scraper and the stirring paddle to rotate on the inner wall of the inner cylinder. The rotation of the scraper paddle can agitate the raw materials at the edge of the inner cylinder. The scraper blade of the scraper paddle can rotate in contact with the inner wall of the inner cylinder, scraping the material adhering to the inner wall of the inner cylinder into the rolling liquid. Compared with the existing rolling liquid preparation and reaction device, the addition of a stirring mechanism can drive the solution at the edge to rotate by the scraper paddle. The rotation of the stirring paddle can reduce the occurrence of the stirring dead zone and improve the stirring quality. The scraper blade of the scraper paddle can adhere to the inner wall of the inner cylinder to scrape off the material adhering to the inner wall, avoiding the imbalance of the mixing ratio and ensuring the cleanliness of the inner wall.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-7 This utility model provides an embodiment of a silicon steel rolling slurry raw material preparation and reaction device, including a reaction mechanism 1 and a feeding device 2. The reaction mechanism 1 includes an inner cylinder 102. The feeding device 2 is installed at the upper end of the reaction mechanism 1 and includes a fixed cover 201, which is fixedly connected to the upper end of the inner cylinder 102. The lower end of the reaction mechanism 1 is equipped with a discharge device 3, which includes a cover 301, which is fixedly connected to the lower end of the inner cylinder 102. A stirring mechanism 4 is installed inside the reaction mechanism 1, and the stirring mechanism 4 includes a bearing 40. 1. The lower center of the fixed cover 201 and the upper center of the cover 301 are fixedly connected to corresponding bearings 401. The inner rings of the bearings 401 are fixedly connected to a rotating shaft 402. The outer wall of the rotating shaft 402 is fixedly connected to a scraper 404 and a stirring paddle 405 distributed vertically. The scraper of the scraper 404 is in contact with the inner wall of the inner cylinder 102. The upper and lower ends of the scraper of the scraper 404 are flush with the upper and lower ends of the inner cylinder 102. A servo motor 403 is installed at the upper end of the fixed cover 201. The output end of the servo motor 403 is connected to the rotating shaft of the rotating shaft 402.

[0023] The output of the servo motor 403 can drive the rotating shaft 402 to rotate, thereby causing the scraper 404 and the stirring paddle 405 to rotate on the inner wall of the inner cylinder 102. The rotation of the scraper 404 can agitate the raw materials at the edge of the inner cylinder 102. Together with the stirring paddle 405 below, it can effectively improve the mixing quality of the raw materials and reduce the occurrence of dead zones in the mixing. The scraper of the scraper 404 can rotate in close contact with the inner wall of the inner cylinder 102, which can scrape the material adhering to the inner wall of the inner cylinder 102 into the rolling liquid, avoiding the imbalance of the mixing ratio and facilitating the cleaning of the inner cylinder 102.

[0024] Please see Figures 3-4 In this embodiment, an outer cylinder 101 is fixedly connected to the outer wall of the inner cylinder 102, and a spirally wound heating tube 103 is installed between the inner cylinder 102 and the outer cylinder 101. During use, the outer cylinder 101 can protect the inner cylinder 102 and the heating tube 103. The spirally wound heating tube 103 can evenly adjust the temperature inside the inner cylinder 102, thereby improving the reaction efficiency and uniformity. The feeding device 2 also includes a feeding pipe 202. Three equally spaced feeding pipes 202 are fixedly connected to the upper end of the fixed cover 201. A diffuser 203 is fixedly connected to the inner wall of each feeding pipe 202. During use, different raw materials can be introduced into the inner cylinder 102 through the feeding pipe 202. The diffuser 203 can diffuse and fall the raw materials, reducing the accumulation of raw materials.

[0025] Please see Figures 4-5 In this embodiment, the upper opening of the feed pipe 202 is fixedly connected to a corrugated pipe 204. The feed pipe 202 is connected to the discharge port of the raw material barrel through the corrugated pipe 204. In use, the corrugated pipe 204 flexibly connects the raw material barrel, which can reduce the impact of vibration on the raw materials. The discharge device 3 also includes a discharge pipe 302. Two symmetrically distributed discharge pipes 302 are fixedly connected to the lower end of the cover 301. A valve 303 is installed on the discharge pipe 302. A mesh cover 304 is threadedly installed at the lower opening of the discharge pipe 302. In use, the discharge path of the material can be controlled by the valve 303. The threaded mesh cover 304 can be easily disassembled and cleaned. The two discharge pipes 302 can be used alternately to facilitate the cleaning of the pipes and the filter screen.

[0026] Please see Figures 5-7In this embodiment, a support device 5 is also installed at the lower end of the reaction mechanism 1. The support device 5 includes a support frame 501 and a support ring 502 fixed to the outer wall of the outer cylinder 101. During use, the reaction mechanism 1 can be supported by the support frame 501. Several shock absorbers 503 are fixed to the upper end of the support frame 501. The output ends of the shock absorbers 503 are fixed to the lower end of the support ring 502. A rubber ring 504 is fixed to the contact point between the support frame 501 and the outer cylinder 101. During use, the shock absorbers 503 can dampen the vibration generated by the stirring mechanism 4, reducing the impact of vibration on the stirring mechanism 4 and the outside. The rubber ring 504 can improve the stability of the load-bearing and further improve the stability of the reaction mechanism 1 and the stirring mechanism 4 during operation.

[0027] During operation, firstly, the corrugated pipe 204 is connected to the raw material barrel to be mixed, the opening of the raw material barrel is opened, and the corresponding mass of raw material flows into the inner cylinder 102. The heating pipe 103 is then activated to bring the inner cylinder 102 to a suitable temperature. Next, the servo motor 403 is activated, and the output end of the servo motor 403 drives the rotating shaft 402 to rotate, thereby causing the scraper 404 and the stirring paddle 405 to stir the raw material solution. After the stirring is completed, the container storing the rolling liquid can be placed at the lower end of the discharge pipe 302, and the valve 303 on the corresponding discharge pipe 302 is opened, allowing the mixed rolling liquid to flow into the container after being filtered through the mesh cover 304. Finally, the fixed cover 201 can be opened to clean the inner wall of the inner cylinder 102, and the mesh cover 304 can be rotated and removed. After cleaning the mesh cover 304, it is reinstalled back into the opening of the discharge pipe 302.

[0028] Through the above steps, the output end of the servo motor 403 can drive the rotating shaft 402 to rotate, thereby driving the scraper 404 and the stirring paddle 405 to rotate on the inner wall of the inner cylinder 102. The rotation of the scraper 404 can drive the raw materials at the edge of the inner cylinder 102 to be stirred. In conjunction with the stirring paddle 405 on the lower side, the stirring dead zone can be effectively reduced. The scraper of the scraper 404 can rotate in close contact with the inner wall of the inner cylinder 102, which can scrape the material adhering to the inner wall of the inner cylinder 102 into the rolling liquid, avoiding the imbalance of the mixing ratio and facilitating the cleaning of the inner cylinder 102. This solves the problem that the stirring effect of a single stirring blade is limited when using the silicon steel rolling liquid raw material mixing reaction device, and that the raw materials adhering to the inner wall of the reaction device affect the reaction.
