Description

Technical Field

[0001] This utility model relates to the field of alumina conveying technology, specifically to a disc feeder for transporting alumina carriers. Background Technology

[0002] Disc feeders are widely used in the quantitative conveying of powdered materials in industries such as metallurgy and chemicals. Their core structure typically includes a frame and a disc that rotates within the frame: the material falls into the chamber through the feed inlet at the top of the frame and is pushed to the discharge outlet by the rotating disc, thus achieving continuous feeding.

[0003] During the production and transportation of alumina carriers, alumina powder is prone to secondary kneading due to process characteristics (such as agglomeration after drying and extrusion during transportation) or environmental humidity factors, forming lumpy agglomerates. Existing disc feeders have a hollow chamber structure inside the frame, allowing materials to fall directly onto the disc surface and then be directly conveyed and discharged.

[0004] However, this method carries the risk of clumping and clogging. The clumps may get stuck at the discharge port and may re-agglomerate due to accumulation and compression during the rotation of the disc, indirectly causing blockage. Utility Model Content

[0005] In view of this, the present invention provides a disc feeder for transporting alumina carriers. Through the synergistic action of the crushing bar and the vibrating motor, alumina clumps can be vibrated and crushed, effectively avoiding the problem of clumps blocking the discharge port or accumulating on the disc surface.

[0006] To solve the above technical problems, this utility model provides a disc feeder for transporting alumina carriers, including a frame, a feed inlet at the top of the frame for pouring in the alumina material to be transported, and a disc at the bottom of the frame connected to a reducer at the bottom of the frame to drive the disc to rotate.

[0007] The inner wall of the frame, above the disc, has multiple crushing bars spaced horizontally. When alumina material enters the frame through the feed inlet, the material falls onto the crushing bars first. Because a gap is formed between adjacent crushing bars to allow alumina powder to pass through, the powder in the material falls through the gap between the crushing bars and onto the disc for transport, while the clumps remain temporarily on the surface of the crushing bars.

[0008] A vibration motor is installed outside the frame and mounted on one side of the bottom surface of the frame. When the vibration motor drives the frame and the crushing bar to vibrate, the crushing bar can break up the alumina clumps. The crushed alumina powder falls onto the disc through the material drop gap, thus vibrating and crushing the alumina clumps and preventing the clumps from blocking the discharge port.

[0009] Multiple crushing bars are arranged in an interlaced grid pattern, which improves the crushing and screening effect.

[0010] The shredding bars are detachably installed inside the frame, which facilitates cleaning and maintenance.

[0011] The frame is divided into two detachable parts connected by a flange. The inner wall of the upper part of the frame has multiple fixing blocks evenly distributed along its circumferential surface, and bolts are fixedly installed on the lower surface of the fixing blocks.

[0012] The shredder is fixed by a ring frame. The surface of the ring frame has holes that fit the bolts. During installation, align the holes on the surface of the ring frame with the bolts, insert the bolts into the holes, and finally tighten them with nuts to fix the ring frame. The detachable design makes it easy to clean and maintain the shredder.

[0013] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0014] 1. When this utility model is used, the pulverizing bar and the vibrating motor work together to break up the alumina clumps during the falling process, effectively avoiding the problem of clumps getting stuck at the discharge port or accumulating on the surface of the disc.

[0015] 2. When this utility model is used, the crushing and screening effects can be improved by the mesh-like crushing strips.

[0016] 3. When using this utility model, the detachable shredder strip facilitates cleaning and maintenance.

[0017] 4. When this utility model is in use, it can be detachably connected to the frame through the ring frame and bolt insertion hole structure. When the surface of the crushing bar is worn or has residual material due to long-term vibration, it can be quickly disassembled and cleaned without disassembling the vibration motor and disc components, thus shortening the disassembly time.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the appendices of the embodiments of this utility model. Figure 1-3 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0024] A disc feeder 201 for transporting alumina carriers, such as Figure 1 , Figure 2 and Figure 3 As shown: It includes a frame 100, with a feed inlet 101 at the top of the frame 100 for pouring in the alumina material to be conveyed. A disc 201 is provided at the bottom of the frame 100, which is connected to a reducer 200 at the bottom of the frame 100. The reducer 200 drives the disc 201 to rotate. A baffle is provided on the inner wall of the frame 100. A discharge port 102 is provided on one side of the bottom of the frame 100, corresponding to the position of the baffle. When the disc 201 rotates, it drives the material on the surface of the disc 201 to rotate. The material is blocked by the baffle and slowly discharged from the discharge port 102. However, the alumina powder may clump due to secondary kneading.

[0025] Multiple crushing bars 300 are distributed horizontally along the inner wall of the frame 100 and above the disc 201. When alumina material enters the frame 100 through the feed inlet 101, the material will first fall onto the crushing bars 300. Since a gap is formed between adjacent crushing bars 300 to allow alumina powder to pass through, the powder in the material will first fall from the gap between the crushing bars 300 and onto the disc 201 for transport, while the clumps will temporarily remain on the surface of the crushing bars 300.

[0026] A vibration motor is installed outside the frame 100. The vibration motor is installed on one side of the bottom surface of the frame 100. When the frame 100 and the crushing bar 300 are vibrated by the vibration motor, the crushing bar 300 can crush the alumina clumps. The crushed alumina powder falls onto the disc 201 through the material feeding gap, so as to crush the alumina clumps by vibration and prevent the clumps from blocking the discharge port 102.

[0027] Specifically, multiple crushing bars are arranged in a staggered, grid-like structure, which improves the crushing and screening effect.

[0028] Specifically, the shredder 300 is detachably installed inside the frame 100, which facilitates cleaning and maintenance of the shredder 300.

[0029] Specifically, the frame 100 is divided into two detachable parts by a flange connection. The inner wall of the upper part of the frame 100 has multiple fixing blocks 400 evenly distributed along its circumferential surface, and bolts 401 are fixedly installed on the lower surface of the fixing blocks 400.

[0030] The pulverizing bar 300 is fixed by the ring frame 301. The surface of the ring frame 301 is provided with insertion holes 302 that are compatible with the bolts 401. During installation, the insertion holes 302 on the surface of the ring frame 301 are aligned with the bolts 401, and then the bolts 401 are inserted into the insertion holes 302. Finally, the nut is used to lock the ring frame 301 in place. The detachable design makes it easy to clean and maintain the pulverizing bar 300.

[0031] First, it should be clarified that this utility model involves a disc 201 for feeding, which is mainly used for crushing and screening agglomerates. It should be noted that the reducer 200, disc 201 and baffle are all existing devices. Since they are not the main technical features of this utility model, the model will not be limited here, nor will their structure be described in detail. Only the usage method and installation position of the crushing bar 300 will be described in detail.

[0032] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
