Abstract
Description
Technical Field
[0001] This utility model relates to the field of barium silicon inoculants, and more specifically, to an environmentally friendly barium silicon inoculant mixing and stirring device. Background Technology
[0002] Barium silicon inoculant is a composite inoculant commonly used in the foundry industry. It is mainly made by mixing silicon, barium, and other rare earth elements in a certain proportion, followed by melting, cooling, and pulverizing. During its production process, to ensure that the components are fully and uniformly mixed, the raw materials are usually mechanically stirred under certain temperature conditions to achieve a uniform physical distribution of the components, thereby ensuring the quality stability of the inoculant and its final performance.
[0003] However, barium silicate inoculants, after being pulverized, exist primarily in the form of fine particles or powder, characterized by their light weight, ease of floating, and easy adsorption. In actual mixing processes, this powder readily adheres to the inner wall of the mixing drum, causing wall adhesion, and simultaneously bridging and clogging at the bottom of the drum or the discharge port, affecting the smoothness of discharge and the uniformity of mixing. Current technologies typically employ timed or manual mechanical vibration of the mixing drum to dislodge the adhering powder and maintain smooth flow. However, this method is not only inefficient but also requires manual intervention and continuous monitoring, making it unsuitable for the demands of continuous and automated production.
[0004] Therefore, based on the above problems, this application proposes an environmentally friendly silicon-barium inoculant mixing and stirring device. Utility Model Content
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an environmentally friendly silicon barium inoculant mixing and stirring device.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] An environmentally friendly silicon-barium inoculant mixing and stirring device includes a shell assembly, which includes a shell with protrusions on its inner wall. A stirring tank assembly is disposed inside the shell, comprising a tank body for holding the silicon-barium inoculant. A stirring component is inserted through the center of the tank body, and a discharge valve is connected to the bottom of the tank body. The stirring component includes a drive motor, with a stirring rod connected to its bottom output end. Several sets of stirring crossbars are sequentially connected to the stirring rod, and a stirring bottom rod is connected to its bottom. The stirring bottom rod includes two sets of second semi-circular connecting rings, which are clamped onto the outer wall of the bottom of the stirring bottom rod. A connecting rod is connected to each of the second semi-circular connecting rings, and an inclined stirring rod is connected to one end of each connecting rod. The inclined stirring rod is inclined and can cooperate with the stirring crossbars to achieve omnidirectional scraping of the inner wall of the tank.
[0008] The present invention is further configured such that: the stirring crossbar includes two sets of first semicircular connecting rings, the two sets of first semicircular connecting rings are arranged facing each other, several sets of through holes are opened at both ends of the first semicircular connecting rings, bolts are provided through the through holes of the first semicircular connecting rings, and silicone strips are provided at both ends of the stirring crossbar.
[0009] The present invention is further configured such that: a plurality of sets of drainage channels are arranged around the inside of the barrel, and the drainage channels are configured as S-shaped.
[0010] The present invention is further configured such that: a plurality of fixing blocks are connected to the outer wall of the barrel, one end of the fixing block is attached to the outer wall of the barrel, and the other end of the fixing block is attached to the protrusion of the inner wall of the outer shell.
[0011] The present invention is further configured such that: a bucket lid is provided on the top of the bucket body, a fixing member is provided at the center of the top of the bucket lid, and a fixing member is installed inside the fixing member.
[0012] The present invention is further configured such that: two sets of discharge ports are provided on the top of the barrel lid, and the two sets of discharge ports are symmetrically arranged relative to the fixing member.
[0013] The present invention is further configured such that: a set of support columns are respectively provided at the four corners of the bottom of the outer shell, and the support columns are arranged in a vertical direction.
[0014] In summary, this application includes at least one of the following beneficial technical effects:
[0015] 1. This device, through a mixing structure combining multiple sets of stirring crossbars and a bottom inclined stirring rod, can comprehensively agitate and disturb the barium silicate inoculant inside the tank from multiple directions and heights, avoiding any dead zones in the mixing process. Simultaneously, a flexible silicone strip is preferably connected to one end of the stirring crossbars. This silicone strip remains in contact with the inner wall of the tank throughout the mixing process, not only scraping off fine powder adhering to the tank wall but also conforming to the curved surface of the tank to clean deep into the drainage channel, preventing powder blockage and ensuring the uniformity and continuous flow of the material throughout the mixing process, significantly improving the mixing effect.
[0016] 2. Several sets of S-shaped flow channels are arranged around the inner wall of the barrel. This structure has a flow-guiding function, and its curved path can effectively disperse the powder accumulated along the wall or bottom. During the stirring process, the synergistic disturbance formed between the flow channels and the stirring device can continuously destroy the bridging structure between the powder particles, thereby effectively suppressing the occurrence of bridging and further avoiding problems such as poor discharge or blockage caused by accumulation, ensuring the smooth and efficient discharge process of the device.

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0027] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.
[0028] Example 1, please refer to Figure 1-8 The present invention provides the following technical solution:
[0029] Specifically, this refers to an environmentally friendly silicon-barium inoculant mixing and stirring device, including a shell assembly 1. The shell assembly 1 includes a shell 11, the inner wall of which has several protrusions to enhance structural stability and limit the positioning of the tank. To enhance overall support, a set of vertical support columns 12 are respectively installed at the four corners of the bottom of the shell 11 to support and stabilize the entire device, ensuring the balance and seismic resistance of the equipment during operation. Inside the shell 11 is a stirring tank assembly 2, which includes a tank 21 for holding the silicon-barium inoculant. A stirring component 3 is inserted through the center of the tank 21, arranged vertically to achieve mixing and stirring of the silicon-barium inoculant. A discharge valve 4 is connected to the center of the bottom of the tank 21 for discharging the material after mixing.
[0030] The barrel 21 is designed as a hollow cylinder with an inclined bottom. The inclined surface can ensure that the barium silicon inoculant slides down smoothly and facilitates discharge. Several sets of fixing blocks 25 are fixedly connected to the outer wall of the barrel 21. One end of the fixing block 25 is fixed to the outer wall of the barrel 21, and the other end abuts against the protrusion on the inner wall of the outer shell 11, so as to realize the anti-rotation and limiting positioning function of the barrel in the outer shell, and improve the overall stability and seismic performance of the structure.
[0031] Specifically, the inner wall of the barrel 21 is provided with several sets of flow channels 26, which extend from the inner wall to the bottom of the barrel to enhance the material guiding capacity of the barrel 21 and prevent bridging at the discharge port. The flow channels 26 are designed with an S-shaped structure and are distributed around the inner wall of the barrel 21. Their curved channel design helps to disperse powder agglomeration and improve flow guiding efficiency.
[0032] The top of the barrel body 21 is provided with a barrel cover 22, and a fixing member 23 is provided in the center of the barrel cover 22 for fixing and supporting the mixing assembly 3. The top of the barrel cover 22 has two sets of symmetrically arranged feeding ports 24, located on both sides of the fixing member 23, for the raw materials to enter during feeding, and to realize the possibility of adding multiple materials simultaneously or in stages.
[0033] The stirring assembly 3 includes a drive motor 31, which is installed at the center of the fixing member 23. The bottom output end of the drive motor 31 is connected to a stirring rod 32, and several sets of stirring crossbars 33 are connected in sequence on the stirring rod 32 to achieve multi-angle tumbling and mixing of the barium silicon inoculant inside the tank.
[0034] The bottom of the stirring rod 32 is further connected to a stirring base rod 34. The stirring base rod 34 is provided with two sets of second semi-circular connecting rings 341. The two sets of connecting rings 341 are fixed to the lower end of the outer wall of the stirring base rod 34 by a clamp. Each set of second semi-circular connecting rings 341 is connected to a connecting rod 342. One end of the connecting rod 342 is further connected to an inclined stirring rod 343. The inclination angle of the inclined stirring rod 343 matches the inclined surface shape of the bottom of the barrel 21, which can fully stir the material at the bottom and guide it towards the discharge port, preventing the material from accumulating in dead corners.
[0035] The stirring crossbar 33 includes two sets of first semicircular connecting rings 331, which are arranged facing each other and have several sets of through holes at both ends. Bolts 332 are inserted through the through holes to achieve a reliable connection between the stirring crossbar 33 and the stirring rod 32. In actual use, the number and installation position of the stirring crossbar 33 can be flexibly adjusted according to the amount of barium silicate inoculant required for stirring to adapt to different stirring needs. By removing the bolts 332, the first semicircular connecting rings 331 can be loosened, allowing them to slide up and down along the stirring rod 32, thereby achieving precise positioning of the stirring crossbar 33 in height. When the amount of material to be stirred is small, the number of stirring crossbars can be appropriately reduced and adjusted to the lower part of the tank to improve the stirring coverage; while when the amount of material is large, multiple sets of stirring crossbars 33 can be conveniently added and evenly distributed at different heights of the stirring rod 32.
[0036] It should be noted that although each set of stirring crossbars 33 is set horizontally, the angle of the part used for stirring is inclined, so that when stirring barium silicon inoculant, stirring crossbars 33 can stir barium silicon inoculant at different vertical positions, and not only stir barium silicon inoculant at the current horizontal position.
[0037] Preferably, the stirring crossbar 33 further includes a flexible silicone strip 333. The width of the silicone strip 333 is wider than the width of the stirring crossbar 33, and the silicone strip 333 can move closely against the inner wall of the barrel 21 as the stirring crossbar rotates during the stirring process. During the movement, it can maintain continuous contact with the inner wall, effectively scraping off the fine barium silicate inoculant powder adhering to the inner wall through contact friction, preventing material accumulation or residue on the barrel wall, thereby avoiding the phenomenon of wall hanging caused by insufficient stirring, and effectively improving the overall mixing uniformity. At the same time, the silicone strip 333 can also follow the curved structure of the inner wall of the barrel 21 to enter the drainage channel 26 for synchronous scraping, preventing powder from being retained or blocked in the drainage channel, and keeping the drainage channel unobstructed.
[0038] It should be noted that the silicone strip 333 shown in the figure, through a tight fit with the stirring rod 34, achieves an all-around scraping function on the inner wall of the barrel 21. Specifically, the silicone strip 333 is made of a highly flexible material with good adhesion, and can effectively scrape along the inner wall of the barrel 21 under the action of the stirring rod 34, thereby avoiding problems such as material adhesion and deposition, and improving the uniformity of mixing and cleaning efficiency.
[0039] Furthermore, the silicone strip 333 is significantly wider in the horizontal direction than the connecting stirring crossbar 33, resulting in a larger coverage area and ensuring thorough scraping of the barrel wall without leaving any blind spots during the stirring process. Moreover, the stirring crossbar 33 is not arranged in a single layer or coaxially, but rather in a staggered structure. Multiple stirring crossbars are staggered at different heights in the vertical direction, allowing the silicone strip 333 to form multiple scraping paths at different heights when rotating. This effectively improves the cleaning coverage of different height areas on the inner wall of the barrel, ensuring that no material remains inside the entire barrel, further enhancing the stirring and cleaning effect.
[0040] The working principle of the environmentally friendly silicon-barium inoculant mixing and stirring device provided by this utility model is as follows:
[0041] See Figure 1 This environmentally friendly barium silicon inoculant mixing and stirring device uses a drive motor 31 to rotate a stirring rod 32. Multiple sets of stirring crossbars 33 connected sequentially to the stirring rod 32 achieve layered mixing of the barium silicon inoculant within the tank 21. A flexible silicone strip 333 is connected to one end of each stirring crossbar 33. During stirring, the silicone strip 333 rotates close to the inner wall of the tank 21, scraping away powder adhering to the wall surface and improving the mixing effect. The bottom stirring rod 34 is connected to a connecting rod 342 via two sets of second semi-circular connecting rings 341. An inclined stirring rod 343 is installed at its end, matching the inclined surface of the tank bottom to effectively agitate the bottom material and guide it to the discharge valve 4, preventing accumulation in dead corners. An S-shaped drainage groove 26 is arranged around the inner wall of the tank 21. Combined with the stirring motion, this prevents bridging of fine powder materials and improves the flowability of the guided material.
[0042] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
