Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of sponge titanium production equipment, and in particular to a storage device for products used in the production of sponge titanium packaging. Background Technology
[0002] In the production of sponge titanium, the temperature of the crushed sponge titanium reaches 200-300℃, and it needs to be cooled to below 80℃ before packaging. Currently, the industry generally uses static storage tanks to temporarily store the materials.
[0003] However, existing static storage tanks have obvious defects: on the one hand, they rely on natural heat dissipation, which is inefficient and takes 15-20 hours to cool down. Moreover, the tanks lack active cooling structures, resulting in poor heat dissipation in the central area and a temperature difference of more than 50°C between the central and peripheral areas. This not only prolongs the cooling time but also exacerbates the oxidation loss of sponge titanium. On the other hand, the uneven particle distribution and static storage cause fine sponge titanium powder to deposit at the bottom and coarse particles to remain at the top, resulting in a fluctuation of more than ±2% in the composition of the packaged finished product, which exceeds the industry standard and further affects the quality of the finished product.
[0004] It is evident that existing static storage tanks can no longer meet the quality requirements for material cooling and storage in the production of sponge titanium packaging, and a new type of storage device is urgently needed to improve the current situation. Utility Model Content
[0005] The purpose of this invention is to overcome the above-mentioned technical deficiencies and propose a material storage device for products in the production of sponge titanium packaging, thereby solving the problems mentioned in the background art.
[0006] To achieve the above technical objectives, the present invention provides a storage device for products used in the production of titanium sponge packaging, comprising: a base and a heat exchange device. A hopper frame is mounted on the base, and a conical unloading section is located at the bottom of the hopper frame. A hopper is located inside the hopper frame, and an anti-overflow ring is located at the bottom of the conical unloading section. The hopper is a cylindrical structure open at both ends, with its lower end rotatably connected to the inner ring surface of the anti-overflow ring. A driving mechanism is mounted on the outer frame, which drives the hopper to rotate within the hopper frame. A water-cooled core, coaxial with the hopper, is located inside the hopper. The lower end of the water-cooled core is fixedly connected to the conical unloading section, and its upper end is connected to the heat exchange device. A paddle is mounted on the inner wall of the hopper, and several heat dissipation fins are mounted on the outer wall.
[0007] Furthermore, the water-cooled core includes a cylindrical section, with conical sections at both ends of the cylindrical section. The diameter of the bottom surface of the conical section is larger than the diameter of the cylindrical section. The paddle is disposed between the two conical sections. A circulating water pipe is provided on the inner wall of the conical and cylindrical sections, with the lower end of the circulating water pipe connected to the outlet of the heat exchange device and the upper end connected to the inlet of the heat exchange device.
[0008] Furthermore, the drive mechanism includes a geared motor and a gear ring. The geared motor is mounted on the outer frame of the hopper, and the gear ring is mounted on the upper end of the hopper. The teeth of the gear ring protrude from the outer frame of the hopper and mesh with the output shaft of the geared motor. A thrust ball bearing is mounted on the top of the outer frame of the hopper. The upper race of the thrust ball bearing is connected to the lower plate surface of the gear ring. A hopper cover is mounted on the upper plate surface of the gear ring, and a guide hopper is mounted on the hopper cover.
[0009] Furthermore, a belt conveyor is installed on the base below the conical unloading section, and a magnetic separation mechanism is installed at the lower end of the conical unloading section.
[0010] Furthermore, the outer side of the hopper frame is wrapped with steel mesh.
[0011] Compared with the prior art, the beneficial effects of this utility model include:
[0012] 1. This utility model significantly improves the cooling efficiency of sponge titanium by setting up a rotating hopper and a water-cooled core inside the hopper. In traditional static storage tanks, sponge titanium particles are piled up together, and heat is difficult to dissipate effectively, resulting in poor cooling effect. However, this utility model uses the rotation of the hopper to make the sponge titanium particles evenly mixed under the agitation of the paddle, while the cooling water in the water-cooled core circulates and removes the heat in the pile, further accelerating the cooling process of sponge titanium.
[0013] 2. This utility model uses a conical discharge section design to allow materials to be discharged smoothly and easily lifted to the next process by the belt conveyor below; at the same time, the magnetic separation mechanism effectively removes iron impurities from the materials and improves the purity of the sponge titanium; the guide hopper at the top of the silo facilitates the addition of materials, while the thrust ball bearing support structure ensures the stability and reliability of the silo during rotation.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0018] Reference Figure 1-3 This utility model provides a storage device for products used in the production of titanium sponge packaging, including a base 1 and a heat exchange device. The heat exchange device can be a common water-cooled heat exchanger, which achieves heat exchange through circulating cooling water.
[0019] A hopper frame 2 is mounted on the base 1, and a conical discharge section 3 is located at the bottom of the hopper frame 2. A belt conveyor 7 is mounted on the base 1 below the conical discharge section 3 to lift the discharged material to the next process. A magnetic separator 6 is installed at the lower end of the conical discharge section 3 to remove ferrous impurities from the material. During the unloading process, the material falls from the conical discharge section 3, first passes through the magnetic separator 6 to remove impurities, and then is conveyed to the next process by the belt conveyor 7, achieving coordinated operation of unloading, impurity removal, and material conveying.
[0020] The bottom of the cone-shaped unloading section 3 is equipped with an anti-overflow ring 301. The inner ring surface of the anti-overflow ring 301 is rotatably connected to the lower end of the hopper 4. Its structural design allows the anti-overflow ring 301 to block the material from spreading outward due to centrifugal force during the rotation of the hopper 4, effectively preventing the material from overflowing.
[0021] The outer frame 2 of the silo houses a silo 4, which is a cylindrical shape open at both ends. Its lower end is rotatably connected to the inner ring of an anti-overflow ring 301, and its upper end is equipped with a gear ring 402. A geared motor 8 is mounted on the outer frame 2. The output shaft of the geared motor 8 meshes with the gear ring 402 via gear transmission. When the geared motor 8 operates, the output shaft drives the gear ring 402 to rotate. The gear ring 402 is then supported by a thrust ball bearing 9, which in turn drives the silo 4 to rotate within the outer frame 2. A thrust ball bearing 9 is mounted on the top of the outer frame 2. The upper race of the thrust ball bearing 9 is connected to the lower plate of the gear ring 402 to support the rotation of the silo 4. A silo cover 10 is mounted on the upper plate of the gear ring 402, and a guide hopper 11 is mounted on the silo cover 10 for easy material loading. In practical applications, to improve the safety of the equipment during operation, the outer frame 2 of the silo is wrapped with a steel mesh to prevent operators or foreign objects from being caught in the rotating silo 4.
[0022] A water-cooled core 5, coaxial with the material hopper 4, is installed inside the hopper. The lower end of the water-cooled core 5 is fixedly connected to the conical unloading section 3. The specific structure of the water-cooled core 5 includes a cylindrical section 501 and conical sections 502 located at its upper and lower ends. The bottom diameter of the conical section 502 is larger than the diameter of the cylindrical section 501. This design allows the water-cooled core 5 to form an effective cooling area inside the material hopper 4. A circulating water pipe 503 is installed on the inner wall of the conical section 502 and the cylindrical section 501, and the lower end of the circulating water pipe 503 is connected to the outlet of the heat exchange device, while the upper end is connected to the inlet of the heat exchange device. This arrangement prevents the high-temperature sponge titanium particles that have just entered the material hopper 4 from contacting the cold end of the water-cooled core 5, ensuring the stability of the cooling process.
[0023] To promote uniform mixing and heat dissipation of materials, paddles 401 are installed on the inner wall of the silo 4, and several heat dissipation fins are installed on the outer wall. The paddles 401 are located between two conical sections 502. As the silo 4 rotates, the paddles 401 can agitate the materials, making them more uniform.
[0024] With the material storage device of this utility model, the cooling time of sponge titanium in actual production can be shortened from the original 15-20 hours to about 5-8 hours, and the temperature difference of sponge titanium at different locations in the silo can be controlled within ±5℃, effectively solving the problem of low cooling efficiency in the prior art; at the same time, the composition fluctuation in the packaged finished product can be controlled within ±1%, which is much better than the industry standard of ±2%, solving the problem of uneven particle distribution.
[0025] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
