Description

Technical Field

[0001] The present invention belongs to the technical field of nickel alloy production, and specifically relates to a production system for corrosion-resistant nickel alloy. Background Art

[0002] Nickel alloy is an alloy composed of nickel as the base and other elements added. Nickel alloy has excellent corrosion resistance in many corrosive media and is widely used in the fields of aerospace, petrochemical, and electronic and electrical. Since nickel alloy is an alloy composed of nickel and one or more other elements, in order to obtain a nickel alloy with specific properties, various raw materials need to be mixed evenly in precise proportions.

[0003] Chinese Patent with application number 202322820654.6 discloses a raw material mixing device for the production of high-temperature nickel alloy, including a stirring tank. A secondary mixing mechanism is arranged inside the fixed tank, and a raw material scraping mechanism is arranged inside the stirring tank. A vibration anti-bonding mechanism is arranged inside the box body and on the surface of the screening frame. This not only enables the raw material mixing device to scrape off the raw materials sticking to the inner wall of the stirring tank during use, avoiding waste of raw materials and making the use effect of the raw material mixing device better, but also enables the raw material mixing device to mix the raw materials more evenly during use. Through vibration, the raw materials stuck together can be dispersed, and moreover, the mixing effect of the raw material mixing device on the raw materials is better during use, and it can better meet the usage requirements of users.

[0004] However, the above-mentioned raw material mixing device for the production of high-temperature nickel alloy has the following deficiencies in actual use: 1. The device mainly relies on stirring to mix the raw materials, and it is difficult to ensure the uniform distribution of raw materials with different particle sizes and densities during the mixing process; 2. Some additives, such as fluxes and antioxidants, may need to be added during the mixing process to improve the performance and mixing effect of the raw materials. When adding, it is easy to cause the additives to accumulate in the same area, and it takes a long time to stir evenly.

[0005] Therefore, a production system for corrosion-resistant nickel alloy is proposed to solve the above problems. Summary of the Invention

[0031] The screening assembly 2 includes two symmetrically arranged screening plates 201 provided on the mixing tank 1.

The lead screw 204 is provided with symmetrically arranged threads with opposite thread directions. The moving directions of the two symmetrically arranged threaded sleeves 203 are opposite. One end of the lead screw 204 is connected to a first motor 205. The screening plate 201 is arranged in the mixing tank 1 to classify and screen the raw materials and mix them. During the stirring process, the raw materials pass through the screening plate 201, and the large-particle raw materials and small-particle raw materials are mixed in different regions respectively, improving the mixing uniformity.

[0032] Specifically, a discharge port 6 is provided at the bottom of the mixing tank 1, and a feed port 7 is provided on the tank cover 3.

[0033] Furthermore, the stirring assembly 4 includes a second motor 401 provided on the tank cover 3. The second motor 401 is connected to a driving gear 402 through a motor shaft. The driving gear 402 is meshed and connected to a driven gear 403. The driven gear 403 is fixedly connected to a stirring shaft 404. The bottom end of the stirring shaft 404 penetrates through the tank cover 3 and extends into the mixing tank 1. Uniformly distributed stirring rods 405 are fixed on the stirring shaft 404 in the mixing tank 1.

[0034] Still further, the additive injection assembly 5 includes a nozzle 501 provided on the stirring rod 405. The nozzle 501 is communicated with a branch channel 502. The branch channel 502 is opened in the stirring rod 405. The branch channel 502 is communicated with a main channel 503. The main channel 503 is opened in the stirring shaft 404. The top end of the main channel 503 is connected to a rotary joint 504. The rotary joint 504 is provided at the top end of the stirring shaft 404. The rotary joint 504 is connected to an additive inlet pipe 505. The additive can be sprayed to various places in the mixing tank 1 by the nozzle 501, making the addition of the additive more dispersed to promote the rapid mixing of the additive and the raw materials.

[0035] It should be noted that the mixing tank 1 is composed of an upper storage section 101, a middle square section 102, and a lower storage section 103 arranged in sequence from top to bottom. The screening plate 201 slides in contact with the middle square section 102.

[0036] It should be noted that through holes 8 are opened at the positions of the screening plate 201 corresponding to the stirring shaft 404, and the stirring shaft 404 passes through the through holes 8.

[0037] It is worth introducing that support legs 9 are fixedly connected to the positions of the four corners at the bottom of the middle square section 102, and reinforcing rods are fixedly connected between adjacent support legs 9.

At the same time, the present invention also includes a power source, a controller, a switch, etc., which are not the main technical points of this patent and will not be elaborated here.

[0039] Working principle and process: Inject granular raw materials into the mixing tank 1 from the feed port 7, start the second motor 401 of the stirring assembly 4, and then the driving gear 402 drives the driven gear 403 to rotate, and then the stirring shaft 404 drives the stirring rod 405 to rotate, so as to stir the granular raw materials. With the stirring, the small granular raw materials will pass through the screening plate 201 and fall into the lower storage section 103, while the large granular raw materials will remain in the upper storage section 101. The large granular raw materials and the small granular raw materials are mixed in different areas respectively, improving the mixing uniformity. When it is necessary to inject additives, the additives are introduced into the additive inlet pipe 505 through a pump, and then sprayed out by the nozzle 501 after passing through the rotary joint 504, the main flow channel 503, and the branch flow channel 502, so that the additives are more dispersed when added, promoting the rapid mixing of the additives and the raw materials. After the large granular raw materials and the small granular raw materials are stirred for a certain time respectively, start the first motor 205 of the screening assembly 2, and then the lead screw 204 rotates. Under the action of the thread, the threaded sleeve 203 drives the moving bracket 202 and the screening plate 201 to move away from each other until the screening plate 201 disengages from the inner cavity of the mixing tank 1. At this time, the large granular raw materials and the small granular raw materials are mixed, and finally the uniformly mixed raw materials are discharged from the discharge port 6, completing the mixing of the nickel alloy raw materials.
