Abstract

The utility model discloses an auxiliary aggregate feeding device for the production of high-purity aluminum-magnesium spinel castable, which includes a base, a feeding pipe, a vertical plate, a motor and a rotating drum. A downward spiral track is provided on the side wall of the rotating drum to form a closed loop with a vertical track. A clamping block in the track is connected to a slider on the guide rail through a connecting piece. The bottom of the slider is connected to a compression spring, and the top is connected to a conical top plate through a connecting rod. The top plate is provided with a dial plate. When the motor drives the rotating drum to rotate, the clamping block moves along the track, causing the slider to drive the top plate to perform a reciprocating up-and-down movement of "slow descent and fast ascent". At the same time, the connecting rod cooperates with the internal thread sleeve to make the top plate rotate synchronously.

This device effectively solves the problems of uneven traditional feeding and easy accumulation, realizes the uniform addition of aggregate through compound motion, improves the mixing efficiency of the castable and the product quality, has a compact structure and strong applicability, and is convenient to be integrated into the existing production line.

Description

Technical Field

[0001] This utility model relates to the technical field of high-purity aluminum-magnesium spinel castable production equipment, and in particular to an auxiliary aggregate feeding device. Background Technology

[0002] In the production process of high-purity aluminum-magnesium spinel castables, auxiliary aggregates, such as corundum (Al2O3) and magnesia (MgO), need to be added to the main raw materials to improve the product's wear resistance, high-temperature strength, or resistance to alkaline slag erosion. However, existing feeding devices have the following problems when adding these auxiliary aggregates:

[0003] Auxiliary aggregates tend to accumulate at the feed inlet, leading to uneven feeding and affecting the stability of product quality. The inability to achieve uniform dispersion of auxiliary aggregates results in insufficient mixing of the main raw materials and auxiliary aggregates, requiring extended mixing time and reducing production efficiency. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model proposes an auxiliary aggregate feeding device.

[0005] The present invention proposes an auxiliary aggregate feeding device, characterized in that it includes a base, a feeding pipe, a vertical plate, a motor, and a rotating drum; multiple sets of connecting frames are connected between the side wall of the base and the side wall of the feeding pipe; the vertical plate and the motor are mounted on the base, a guide rail is vertically mounted on the vertical plate, the drive shaft of the motor is connected to the rotating drum, and the axis of the rotating drum is parallel to the guide rail.

[0006] The side wall of the rotating cylinder has a spiral track extending downwards and a vertical track extending upwards. The two ends of the vertical track are connected to the two ends of the spiral track to form a closed track. A locking block is slidably connected inside the track. A slider is slidably connected vertically on the guide rail. The slider and the locking block are located on the same horizontal plane. The slider and the locking block are connected by a connector. A spring is connected between the bottom of the slider and the top side of the base.

[0007] The top of the slider is connected to a connecting rod, and the top of the connecting rod is connected to a top plate, which is located below the feed tube.

[0008] Preferably, an internally threaded sleeve is installed on the top of the guide rail, the connecting rod is vertically rotatably connected to the top of the slider, and a thread is provided in the middle of the outer side wall of the connecting rod, and the thread of the connecting rod is threadedly connected to the internally threaded sleeve.

[0009] Preferably, the top plate is a cone with its tip facing the feed pipe.

[0010] Preferably, the top plate has multiple sets of levers on its conical surface, and the multiple sets of levers are evenly distributed around the circumference of the top plate.

[0011] Preferably, the connecting frame is provided in three sets, and the three sets of connecting frames are evenly distributed around the axis of the material tube below.

[0012] Preferably, the motor's wires are located inside the connecting frame.

[0013] Preferably, the spring is a compression spring. When the block slides downward along the spiral track, the slider overcomes the spring force and slowly descends, and the spring is compressed to store energy. When the block enters the vertical track and slides upward, the spring releases energy to drive the slider to bounce upward quickly.

[0014] Preferably, the surface of the top plate is coated with a ceramic coating.

[0015] The auxiliary aggregate feeding device proposed in this utility model can uniformly disperse and add auxiliary aggregates during the mixing process of high-purity aluminum-magnesium spinel castable raw materials. Through the combined rotation and reciprocating lifting motion of the top plate, the auxiliary aggregates are thrown in all directions under the action of centrifugal force, which significantly improves the mixing uniformity of auxiliary aggregates and raw materials. High-efficiency feeding: the impact motion generated by the spring energy storage and release mechanism effectively prevents aggregates from accumulating at the feed port and ensures continuous feeding. It also enhances the mixing effect and mixing efficiency of aggregate additives.

[0016] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0022] The embodiments of this utility model are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0023] like Figures 1-4 The auxiliary aggregate feeding device shown includes a base 1, a feeding pipe 8, a vertical plate 2, a motor 403, and a rotating drum 4; multiple sets of connecting frames 801 are connected between the side wall of the base 1 and the side wall of the feeding pipe 8; the vertical plate 2 and the motor 403 are mounted on the base 1, a guide rail 3 is vertically mounted on the vertical plate 2, the drive shaft of the motor 403 is connected to the rotating drum 4, and the axis of the rotating drum 4 is parallel to the guide rail 3;

[0024] The rotating cylinder 4 has a spiral track 401 extending downwards and a vertical track 402 extending upwards on its side wall. The two ends of the vertical track 402 are connected to the two ends of the spiral track 401 to form a closed track. A locking block 404 is slidably connected inside the track. A slider 301 is vertically slidably connected on the guide rail 3. The slider 301 and the locking block 404 are located on the same horizontal plane. The slider 301 and the locking block 404 are connected by a connector 302. A spring 303 is connected between the bottom of the slider 301 and the top side of the base 1.

[0025] The top of the slider 301 is connected to a connecting rod 5, and the top of the connecting rod 5 is connected to a top plate 7, which is located below the feed tube 8.

[0026] The top of the guide rail 3 is equipped with an internal threaded sleeve 6. The connecting rod 5 is vertically rotatably connected to the top of the slider 301. The middle part of the outer wall of the connecting rod 5 is threaded. The thread of the connecting rod 5 is threadedly connected to the internal threaded sleeve 6, so that the connecting rod 5 can rotate during the lifting process, thereby driving the top plate 7 to rotate.

[0027] The top plate 7 is a cone with the tip facing the feed pipe 8. This design allows the auxiliary aggregate to be evenly distributed along the cone surface after falling onto the top plate 7.

[0028] The top plate 7 has multiple sets of deflector plates 701 on its conical surface. The multiple sets of deflector plates 701 are evenly distributed around the circumference of the top plate 7. The setting of the deflector plates 701 further enhances the dispersion effect of the auxiliary aggregate.

[0029] The connecting frame 801 is provided in three sets, and the three sets of connecting frames 801 are evenly distributed around the axis of the material tube 8 below, which ensures the stability of the device structure.

[0030] The wires of the motor 403 are located inside the connecting frame 801. This design not only makes the device look neat, but also protects the wires and improves the safety of the device.

[0031] The spring 303 is a compression spring 303. When the locking block 404 slides down along the spiral track 401, the slider 301 slowly descends against the elastic force of the spring 303, and the spring 303 is compressed and stores energy. When the locking block 404 enters the vertical track 402 and slides up, the spring 303 releases energy to drive the slider 301 to bounce up quickly, thereby causing the top plate 7 to vibrate up and down, which helps to assist in the feeding and dispersion of aggregates.

[0032] The top plate 7 is coated with a ceramic coating, which improves its wear resistance and corrosion resistance, allows for the accumulation of auxiliary aggregates, and extends the service life of the device.

[0033] The base 1 is fixed above the raw material mixing device, and the feed pipe 8 is connected to the auxiliary aggregate storage container to ensure that the aggregate can fall smoothly into the top plate 7.

[0034] Operation process:

[0035] When the motor 403 is started, the rotating drum 4 rotates, driving the locking block 404 to move along the track, so that the slider 301 can achieve a reciprocating motion of "slow descent and fast rise";

[0036] During the lifting and lowering process, the connecting rod 5 rotates due to the screw drive, which drives the top plate 7 to rotate synchronously.

[0037] During the mixing process of high-purity aluminum-magnesium spinel castable raw materials, auxiliary aggregates fall from the feed pipe 8 onto the rotating top plate 7, and under the action of centrifugal force and impact force, they are evenly dispersed into the mixing device in a parabolic manner.

[0038] Reciprocating lifting motion: Motor 403 drives the rotating drum 4 to rotate. When the locking block 404 slides down along the spiral track 401, the slider 301 slowly descends against the elastic force of the spring 303, and the spring 303 stores energy. After the locking block 404 enters the vertical track 402, the spring 303 releases energy to drive the slider 301 to rise rapidly, which drives the top plate 7 to generate an upward impact motion.

[0039] Rotational motion: During the lifting and lowering process, the connecting rod 5 generates a synchronous rotational motion due to the cooperation between the thread and the internal thread sleeve 6, causing the top plate 7 to rotate continuously during the lifting process.

[0040] Aggregate dispersion mechanism: Auxiliary aggregates fall from the feed pipe 8 onto the rotating top plate 7 and are dispersed along the conical surface under the action of centrifugal force; the rapid upward movement of the top plate 7 gives the aggregates an initial upward velocity, forming a parabolic trajectory, and they fall evenly into the raw material mixing device below.

[0041] It should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0042] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0044] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.
