Aluminum alloy metal mixing tank with a scraping mechanism

Abstract

This utility model discloses an aluminum alloy metal mixing tank with a scraping mechanism, including a mixing barrel, a partition, a mixing mechanism, and a scraping mechanism. Through the mixing mechanism, the drive mechanism rotates the first stirring blade on the rotating rod, simultaneously rotating the auxiliary stirring assembly. This allows for mixing of the metal raw materials in the mixing barrel from different angles and positions, greatly increasing the mixing coverage and intensity, effectively avoiding the uneven mixing problem caused by traditional single-stirring methods, and significantly improving the mixing efficiency and uniformity of the metal raw materials. The scraping mechanism comprehensively scrapes the inner wall. Simultaneously, the four sets of lower scraping plates in the mixing mechanism can promptly scrape away accumulated material at the bottom during the rotation of the rotating rod. This combined upper and lower scraping method ensures that there is no material residue on the inner wall and bottom of the mixing barrel, avoiding the impact of accumulated material on the effective volume of the mixing tank and improving mixing efficiency.

Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy metal mixing technology, specifically to an aluminum alloy metal mixing tank with a scraping mechanism. Background Technology

[0002] In the field of aluminum alloy metal processing, the uniformity of metal raw material mixing plays a crucial role in the quality of the final product. To achieve efficient and uniform metal raw material mixing, mixing tanks are widely used as a key piece of equipment.

[0003] Traditional aluminum alloy metal mixing tanks are mostly simple in structure, usually relying on a single stirring device to mix the metal raw materials inside the tank. However, this single stirring method has many limitations in practical applications. On the one hand, due to the relatively simple layout and movement of the stirring blades, it is difficult to fully stir the metal raw materials in different parts of the tank, resulting in uneven mixing, which in turn affects the performance and quality of aluminum alloy products. On the other hand, during the stirring process, the metal raw materials tend to adhere to the inner wall and bottom of the mixing tank, forming material accumulation. This accumulation not only occupies the space inside the tank, reducing the effective volume of the mixing tank and affecting the mixing efficiency, but also may deteriorate during long-term use, contaminating the raw materials added later. Therefore, we need to propose an aluminum alloy metal mixing tank with a scraping mechanism. Utility Model Content

[0004] The purpose of this utility model is to provide an aluminum alloy metal mixing tank with a scraping mechanism. By setting the mixing mechanism, the metal raw materials can be fully mixed. At the same time, with the effective scraping mechanism, the accumulated material on the tank wall and bottom can be scraped off in time, so as to ensure the normal operation of the mixing tank and the quality of aluminum alloy metal products, thereby solving the problems mentioned in the background art.

The rotating rod 31 is rotatably installed in the center of the partition 2. The top end of the rotating rod 31 is fixedly installed through the mixing tank 1 and the output shaft of the drive motor 32. Four sets of lower scrapers 34 are fixedly installed in a ring array on the bottom outer wall. Three sets of first stirring blades 33 are fixedly installed on the outer wall of the rotating rod 31.

[0028] It should be noted that the mixing tank 1 is made of 6061-T6 aluminum alloy in one piece, and the inner surface is anodized to form a 50μm hard oxide film with a roughness Ra≤0.8μm; the partition 2 is made of 304 stainless steel plate; the output shaft of the drive motor 32 of the mixing mechanism 3 is connected to the rotating rod 31 by a coupling; the drive motor 32 drives the first stirring blade 33 and the lower scraper 34 on the rotating rod 31 to rotate, thereby stirring and scraping the metal raw materials inside the mixing tank 1 and on the bottom surface.

[0029] The rotating rod 31 is made of 40Cr alloy steel with heat treatment (hardness HRC28-32), with an outer diameter of φ60mm and a surface hard chrome plating treatment (plating thickness 0.05mm). The drive motor 32 is a SEW-EURODRIVE brand MDX61 B0075-5A3-4-00 three-phase asynchronous motor with a rated power of 7.5kW, a rated speed of 1450rpm, and a protection level of IP55. The first stirring blade 33 is CNC cut from a 6mm thick 5083 aluminum alloy plate with a blade inclination angle of 45° and a width of 120mm. The lower scraper 34 is made of polyurethane elastomer (Shore hardness 90A) and has an embedded 3mm thick aluminum alloy reinforcing plate.

[0030] In an optional embodiment, the mixing mechanism 3 further includes an auxiliary stirring assembly 35, which includes a driving gear 351, a driven gear 352, a rotating shaft 353, and a second stirring blade 354. The driving gear 351 is fixedly sleeved on the top outer wall of the rotating rod 31, and four sets of driven gears 352 are annularly meshed on the outer wall of the driving gear 351. The rotating shaft 353 is fixedly inserted into the interior of each of the four sets of driven gears 352. The bottom of the rotating shaft 353 passes through the partition 2 and two sets of second stirring blades 354 are fixedly installed thereon.

[0031] It should be noted that the driving gear 351 has a module m=4, a number of teeth z=20, and is made of 20CrMnTi carburized and quenched (tooth surface hardness HRC58-62); the driven gear 352 has a module m=4, a number of teeth z=40, and a transmission ratio i=1:2; the rotating shaft 353 is made of φ40mm 42CrMo alloy steel, and the surface is treated with high frequency quenching (hardness HRC50-55); the second stirring blade 354 is made of the same material as the first stirring blade 33.

[0032] In an optional embodiment: the outer walls of the rotating rod 31 and the rotating shaft 353 are rotatably mounted to the partition plate 2 and the mixing tank 1 via bearings, and the first stirring blade 33 on the rotating rod 31 and the second stirring blade 354 on the rotating shaft 353 are staggered and alternately arranged.

[0033] It should be noted that the top of the rotating rod 31 and the rotating shaft 353 uses an SKF6312 deep groove ball bearing (basic rated dynamic load C = 63kN), and the bottom uses a TIMKEN HM88460 / 10 tapered roller bearing (rated dynamic load C = 105kN); the first stirring blade 33 and the second stirring blade 354 are staggered in the height direction.

[0034] In an optional embodiment: the first stirring blade 33 and the second stirring blade 354 are both composed of three blades, and the bottom of the lower scraper 34 slides against the surface of the inner wall of the bottom of the mixing tank 1.

[0035] It should be noted that the drive gear 351 rotates with the rotating rod 31, which in turn drives the four sets of driven gears 352 to rotate, thereby causing the rotating shaft 353 to drive the second stirring blade 354 to rotate. This method of multiple stirring components working together can stir the metal raw materials in the mixing tank 1 from different angles and positions, greatly increasing the stirring coverage and stirring force.

[0036] In an optional embodiment: the scraping mechanism 5 includes an electro-hydraulic rod 51, a connecting block 52 and an annular scraper 53. Two sets of electro-hydraulic rods 51 are fixedly installed on the top of the partition 2, and the tops of the two sets of electro-hydraulic rods 51 pass through the mixing tank 1 and extend out of the mixing tank 1. One end of the telescopic end of the two sets of electro-hydraulic rods 51 passes through the partition 2 and is fixedly installed with a connecting block 52. An annular scraper 53 is fixedly installed on one side of the two sets of connecting blocks 52, and the outer wall of the annular scraper 53 is in contact with the inner wall of the mixing tank 1.

[0037] It should be noted that the electric hydraulic rod 51 is a TOYO brand TLB-100×500 model with a rated thrust of 10kN and a stroke of 500mm. It has a built-in magnetostrictive displacement sensor (model: MTSRH-M-0500-MD601A) with a position accuracy of ±0.05mm. The connecting block 52 is made of cast aluminum ZL101A material with an internal reinforcing rib structure. The annular scraper 53 is made of three 120° arc plates spliced ​​together. The base material is 6063 aluminum alloy with a 3mm thick PTFE coating. The two sets of electric hydraulic rods 51 can drive the connecting block 52 connected to them to move up and down, thereby making the annular scraper 53 slide along the inner wall of the mixing barrel 1 to scrape the inner wall thoroughly.

[0038] Two sets of electro-hydraulic rods 51 use Beckhoff CX5130 motion controllers to synchronously control two Bosch Rexroth IndraDrive servo drives via EtherCAT bus, achieving a synchronization accuracy of ±0.05mm.

[0039] In an optional embodiment, a feed hopper 4 is also included, which is mounted on top of the mixing tank 1 and has its bottom extending into the interior of the mixing tank 1 and penetrating the partition 2.

[0040] It should be noted that the feed hopper 4 is made of 3mm thick 316L stainless steel, with polished inner wall (Ra≤0.4μm), hopper opening diameter φ300mm, cone angle 60°, and a cover plate hinged to the top.

[0041] In an optional embodiment, the system further includes a discharge pipe 6 and a solenoid valve 7. The discharge pipe 6 is installed through the bottom of the mixing tank 1, and the solenoid valve 7 is installed on the outer wall of the discharge pipe 6.

[0042] It should be noted that the discharge pipe 6 is a seamless aluminum alloy pipe (6063-T5) with a diameter of φ80mm, and the inner wall is coated with a ceramic wear-resistant layer (thickness of 0.3mm). The discharge port is connected by a quick-release clamp. The solenoid valve 7 is an ASCO brand 8210G004 direct-acting solenoid valve with a nominal diameter of DN80, applicable medium temperature of -20~+150℃, and response time ≤30ms.

[0043] Working principle: When using this invention, the operator adds the aluminum alloy metal raw material to be mixed into the mixing tank 1 through the feed hopper 4. The drive motor 32 starts working, and its output shaft drives the rotating rod 31 to rotate at the center of the partition 2. The three sets of first stirring blades 33 fixedly installed on the outer wall of the rotating rod 31 move in a circular motion within the mixing tank 1 as the rotating rod 31 rotates, thus stirring and mixing the metal raw material.

[0044] When the rotating rod 31 rotates, the driving gear 351 rotates accordingly, driving the four sets of driven gears 352 to rotate synchronously. The rotation of the driven gears 352 causes the rotating shaft 353 to drive the second stirring blade 354 to rotate. The first stirring blade 33 and the second stirring blade 354 stir the metal raw materials from different angles and positions, which can fully break the relative static state between the metal raw materials, so that the metal raw materials of different components can be mixed together more evenly, greatly improving the mixing efficiency and uniformity. During the rotation of the rotating rod 31, the lower scraper 34 will rotate with the rotating rod 31 to scrape off the metal raw materials adhering to the bottom of the mixing tank 1, preventing the raw materials from accumulating at the bottom and ensuring that the raw materials at the bottom of the mixing tank 1 can also participate in the mixing process.

[0045] When it is necessary to scrape the inner wall of the mixing barrel 1, the electric hydraulic rod 51 starts to work. The telescopic ends of the two sets of electric hydraulic rods 51 move downward, driving the connecting block 52 to move downward. As the connecting block 52 moves downward, the annular scraper 53 slides down along the inner wall of the mixing barrel 1 to scrape off the metal raw materials adhering to the inner wall of the mixing barrel 1, so that these raw materials fall back into the mixing barrel 1 to participate in mixing or prepare for discharge.

[0046] After the metal raw materials are mixed evenly, the operator opens the solenoid valve 7 installed on the outer wall of the discharge pipe 6. The mixed aluminum alloy metal raw materials in the mixing tank 1 flow out of the mixing tank 1 through the discharge pipe 6 under the action of gravity. By controlling the opening degree and time of the solenoid valve 7, the flow rate and speed of the discharge can be precisely controlled, which facilitates the connection with subsequent production processes.

[0047] The control method in this application is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Furthermore, this application is mainly used to protect the structure and shape and their combination, so the control method and circuit connection will not be explained in detail in this application.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
