Description

Technical Field

[0001] This utility model relates to the field of electrical porcelain processing technology, specifically to a raw material mixing device for electrical porcelain processing. Background Technology

[0002] Electrical porcelain is an insulating ceramic material used in power systems. It is typically made from natural mineral raw materials such as kaolin, feldspar, and quartz through processing. Electrical porcelain possesses excellent insulation properties, mechanical strength, and heat resistance, enabling it to operate stably in harsh environments such as high voltage and strong electric fields, effectively ensuring the safe operation of power equipment. It is widely used in transmission lines, substations, and electrical equipment, such as insulators, bushings, and surge arresters, and is an indispensable key material in power systems.

[0003] In the raw material processing of electrical porcelain, kaolin, feldspar, and quartz need to be crushed before mixing. However, in actual production, due to wear and tear of crushing equipment, excessively fast feeding speed, or insufficient crushing time, some raw materials are not fully crushed. When these incompletely crushed raw materials enter the mixing stage, they will cause uneven particle size of the mixture. In the subsequent molding stage, differences in the density of the green body are likely to occur, resulting in local stress concentration and defects such as cracking and deformation during sintering. Large particles that are not completely crushed may also affect the insulation performance and mechanical strength of electrical porcelain, reducing the product qualification rate. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a raw material mixing device for electrical porcelain processing, which has the advantage of filtering large-particle raw materials to ensure complete mixing, thus solving the problem mentioned in the background technology of uneven mixing caused by the incorporation of insufficiently crushed large-particle raw materials, which affects the quality of electrical porcelain.

[0005] To achieve the goal of filtering large particles and ensuring complete mixing of the raw materials, this utility model provides the following technical solution: A mixing tank is included, with a top plate installed on its top. Three feeding frames are connected and fixedly connected through the top of the top plate. A shaking groove is formed in the inner cavity of one of the feeding frames, penetrating the top of the top plate. A baffle groove is formed on the top side of the top of the shaking groove. An arc-shaped plate is slidably connected to the inner cavity of one of the shaking grooves. Evenly distributed springs are fixedly connected to the top of the arc-shaped plate, with the side of the springs furthest from the arc-shaped plate fixedly connected to the shaking groove. The top of the inner cavity, not the top of the arc-shaped plate, is fixedly connected to an annular baffle on the side away from the spring, and the annular baffle slides in the baffle groove. A filter screen is fixedly connected through and in the middle of the arc-shaped plate. An angled abutment block is fixedly connected to the bottom middle of the filter screen. A motor is installed in the top middle of the top plate. An output rod is fixedly connected through and in the bottom of the motor. Three swing rods are fixedly connected to the upper part of the outer wall of the output rod. An abutment rod is rotatably connected through and in the middle of one of the swing rods, and one side of the abutment rod abuts against the angled abutment block.

[0006] As a further embodiment of this utility model: a connecting rod is fixedly connected to the outer wall of the output rod on the side away from the swing rod, and a scraping rod is fixedly connected to the connecting rod on the side away from the output rod, and the scraping rod is in contact with the inner cavity of the mixing tank.

[0007] As a further improvement of this utility model: L-shaped connecting rods are fixedly connected to the bottom four sides of the output rod, and the L-shaped connecting rods are fixedly connected to one end of the scraping rod in accordance with the principle of the output rod.

[0008] As a further improvement of this utility model: the bottom of the mixing tank is provided with a discharge port, and one side of the outer wall of the mixing tank is provided with a water inlet.

[0009] Compared with the prior art, the beneficial effects of this utility model are: In this invention, when powdered raw materials are fed into the feeding frame, the filter screen intercepts large particles of impurities, ensuring the purity of the raw materials from the source. At the same time, the motor drives the output rod to rotate clockwise, causing the swing rod and the contact rod to form a linkage structure. During the rotation, the contact rod contacts the angled contact block, pushing the filter screen and the arc plate to slide upward along the shaking groove, synchronously compressing the spring to store energy. When the contact rod disengages, the spring releases its elastic potential energy, driving the filter screen to generate high-frequency shaking, ensuring that the fine particles remaining on the surface of the filter screen are thoroughly screened, effectively avoiding screen blockage and improving screening efficiency.

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] Please see Figures 1-4 In this embodiment of the present invention, a raw material mixing device for electrical porcelain processing includes a mixing tank 1. A top plate 2 is installed on the top of the mixing tank 1. Three feeding frames 3 are connected and fixedly connected through the top of the top plate 2. A vibration groove 4 is opened in the inner cavity of the top plate 2 through the feeding frame 3. The feeding frame 3 can slide in the baffle groove 5 through the annular baffle 8 to prevent the raw material from entering the vibration groove 4 and causing an impact. A baffle groove 5 is opened on the top side of the top plate 2 located in the vibration groove 4. The inner cavity of the vibration groove 4 is slidably connected to the top of the top plate 2. An arc-shaped plate 6 is attached, with evenly distributed springs 7 fixedly connected to its top. The side of the springs 7 furthest from the arc-shaped plate 6 is fixedly connected to the top of the inner cavity of the vibration groove 4. Alternatively, an annular baffle 8 is fixedly connected to the side of the arc-shaped plate 6 furthest from the springs 7, and slides within a baffle groove 5. A filter screen 9 is threaded through and fixedly connected to the middle of the arc-shaped plate 6. The filter screen 9 is made of stainless steel and will not be deformed or damaged when the angled contact block 10 moves the filter screen 9 upwards. This ensures that filter screen 9 maintains stable filtration performance when filtering materials with high hardness. An angled contact block 10 is fixedly connected to the bottom center of filter screen 9. A motor 11 is installed at the top center of top plate 2. The bottom of motor 11 penetrates top plate 2 and is fixedly connected to output rod 12. Three swing rods 13 are fixedly connected to the upper part of the outer wall of output rod 12. One side of each swing rod 13 is rotatably connected to a contact rod 14, and one side of the contact rod 14 abuts against the angled contact block 10. 11 Drive output rod 12 to rotate clockwise, causing swing rod 13 and contact rod 14 to form a linkage structure. During rotation, contact rod 14 contacts angled contact block 10, pushing filter screen 9 and arc plate 6 to slide upward along vibration groove 4, synchronously compressing spring 7 to store energy. When contact rod 14 disengages, spring 7 releases elastic potential energy, driving filter screen 9 to generate high-frequency vibration, ensuring that fine particles remaining on the surface of filter screen 9 are thoroughly screened, effectively avoiding screen clogging, and improving screening efficiency by more than 40%. A connecting rod 15 is fixedly connected to the outer wall of the output rod 12 on the side away from the swing rod 13. A scraping rod 16 is fixedly connected to the side of the connecting rod 15 away from the output rod 12, and the scraping rod 16 is in close contact with the inner cavity of the mixing tank 1. At the same time, the output rod 12 drives the connecting rod 15 and the scraping rod 16 to work together. The connecting rod 15 rotates to mix the raw materials evenly, and the scraping rod 16 rotates synchronously against the inner wall of the tank to completely scrape off the raw materials adhering to the tank wall, preventing local raw material agglomeration. During the stirring process, the output rod 1... L-shaped connecting rods 17 are fixedly connected to the bottom four sides of the mixing tank 1, and the L-shaped connecting rods 17 and the output rods 12 are fixedly connected to one end of the scraper rod 16. The L-shaped connecting rods 17 can prevent the scraper rod 16 from blocking the discharge port 18 and affecting the discharge. The bottom of the mixing tank 1 is provided with a discharge port 18. The inner cavity of the discharge port 18 is provided with a solenoid valve, which can control the discharge inside the mixing tank 1. A water inlet 19 is provided through one side of the outer wall of the mixing tank 1, and the water injection volume can be precisely controlled through the water inlet 19.

[0014] The working principle of this utility model is as follows: When the powdered raw material is put into the feeding frame 3, the filter screen 9 intercepts large particles of impurities, ensuring the purity of the raw material from the source. At the same time, the motor 11 drives the output rod 12 to rotate clockwise, which drives the swing rod 13 and the contact rod 14 to form a linkage structure. During the rotation, the contact rod 14 contacts the angled contact block 10, pushing the filter screen 9 and the arc plate 6 to slide upward along the shaking groove 4, and simultaneously compressing the spring 7 to store energy. When the contact rod 14 disengages, the spring 7 releases its elastic potential energy, driving the filter screen 9 to generate high-frequency shaking, ensuring that the fine particles remaining on the surface of the filter screen 9 are thoroughly screened, effectively avoiding screen blockage, and improving the screening efficiency by more than 40%. After the mixing tank 1 is filled with qualified raw materials, the motor 11 is restarted and the output rod 12 is rotated counterclockwise. At this time, the contact rod 14 automatically folds when it comes into contact with the angled contact block 10, and no longer pushes the angled contact block 10 upward, thus avoiding interference with the screening structure. At the same time, the output rod 12 drives the connecting rod 15 and the scraper rod 16 to work together. The connecting rod 15 rotates to mix the raw materials evenly, and the scraper rod 16 rotates synchronously close to the inner wall of the tank to completely scrape off the raw materials attached to the tank wall, preventing local raw material agglomeration. During the stirring process, the water injection volume is precisely controlled through the water inlet 19, and in conjunction with the rotating stirring components, the raw materials and water are fully mixed to form a uniform mud-like material. After the mixing process is completed, the evenly mixed material is stably discharged through the discharge port 18, providing high-quality raw materials for subsequent processes such as electric porcelain blank forming and high-temperature sintering, effectively ensuring the mechanical strength and insulation performance of electric porcelain products.
